Ergocalciferol
Ergocalciferol appears as odorless white crystals. Used as a dietary supplement and food additive. (EPA, 1998) Vitamin D2 is a vitamin D supplement and has been isolated from alfalfa. It has a role as a nutraceutical, a bone density conservation agent, a rodenticide and a plant metabolite. It is a seco-ergostane, a hydroxy seco-steroid and a vitamin D. Ergocalciferol is an inactivated vitamin D analog. It is synthesized by some plants in the presence of UVB light. The production of ergocalciferol was prompted by the identification of dietary deficiency, more specifically vitamin D, as the main causative factor for the development of rickets. Ergocalciferol was isolated for the first time from yeast in 1931 and its structure was elucidated in 1932. Ergocalciferol is considered the first vitamin D analog and is differentiated from [cholecalciferol] by the presence of a double bond between C22 and C23 and the presence of a methyl group at C24. These modifications reduce the affinity of ergocalciferol for the vitamin D binding protein resulting in faster clearance, limits its activation, and alters its catabolism. The first approved product containing ergocalciferol under the FDA records was developed by US Pharm Holdings and was FDA approved in 1941. Ergocalciferol is a Provitamin D2 Compound. Ergocalciferol is a natural product found in Pseudo-nitzschia multistriata, Humulus lupulus, and other organisms with data available. Ergocalciferol is vitamin D2, a fat-soluble vitamin important for many biochemical processes including the absorption and metabolism of calcium and phosphorus. In vivo, ergocalciferol is formed after sun (ultraviolet) irradiation of plant-derived ergosterol, another form of vitamin D. Ergocalciferol is the form of vitamin D usually found in vitamin supplements. (NCI04) Ergocalciferol is a form of Vitamin D, also called vitamin D2. It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol. Ergocalciferol is used in the treatment of hypcalcemia and in dialysis-dependent renal failure. Ergoalcifediol is a fat soluble steroid hormone precursor of vitamin D that contributes to the maintenance of normal levels of calcium and phosphorus in the bloodstream. Vitamin D2 is the form of vitamin D most commonly added to foods and nutritional supplements. Vitamin D2 must be transformed (hydroxylated) into one of two active forms via the liver or kidney.

Vitamin D3
Vitamin d3 appears as fine colorless crystals. Water insoluble. (NTP, 1992) Calciol is a hydroxy seco-steroid that is (5Z,7E)-9,10-secocholesta-5,7,10(19)-triene in which the pro-S hydrogen at position 3 has been replaced by a hydroxy group. It is the inactive form of vitamin D3, being hydroxylated in the liver to calcidiol (25-hydroxyvitamin D3), which is then further hydroxylated in the kidney to give calcitriol (1,25-dihydroxyvitamin D3), the active hormone. It has a role as a human metabolite and a geroprotector. It is a seco-cholestane, a hydroxy seco-steroid, a member of D3 vitamins, a secondary alcohol and a steroid hormone. Vitamin D, in general, is a secosteroid generated in the skin when 7-dehydrocholesterol located there interacts with ultraviolet irradiation - like that commonly found in sunlight. Both the endogenous form of vitamin D (that results from 7-dehydrocholesterol transformation), vitamin D3 (cholecalciferol), and the plant-derived form, vitamin D2 (ergocalciferol), are considered the main forms of vitamin d and are found in various types of food for daily intake. Structurally, ergocalciferol differs from cholecalciferol in that it possesses a double bond between C22 and C23 and has an additional methyl group at C24. Finally, ergocalciferol is pharmacologically less potent than cholecalciferol, which makes vitamin D3 the preferred agent for medical use. Appropriate levels of vitamin D must be upheld in the body in order to maintain calcium and phosphorus levels in a healthy physiologic range to sustain a variety of metabolic functions, transcription regulation, and bone metabolism. However, studies are also ongoing to determine whether or not cholecalciferol may also play certain roles in cancer, autoimmune disorders, cardiovascular disease, and other medical conditions that may be associated with vitamin D deficiency. Cholecalciferol is a Vitamin D. Cholecalciferol is a natural product found in Taiwanofungus camphoratus, Theobroma cacao, and other organisms with data available. Cholecalciferol is a steroid hormone produced in the skin when exposed to ultraviolet light or obtained from dietary sources. The active form of cholecalciferol, 1,25-dihydroxycholecalciferol (calcitriol) plays an important role in maintaining blood calcium and phosphorus levels and mineralization of bone. The activated form of cholecalciferol binds to vitamin D receptors and modulates gene expression. This leads to an increase in serum calcium concentrations by increasing intestinal absorption of phosphorus and calcium, promoting distal renal tubular reabsorption of calcium and increasing osteoclastic resorption. Cholecalciferol is only found in individuals that have used or taken this drug. It is a derivative of 7-dehydroxycholesterol formed by ultraviolet rays breaking of the C9-C10 bond. It differs from ergocalciferol in having a single bond between C22 and C23 and lacking a methyl group at C24. [PubChem]The first step involved in the activation of vitamin D3 is a 25-hydroxylation which is catalysed by the 25-hydroxylase in the liver and then by other enzymes. The mitochondrial sterol 27-hydroxylase catalyses the first reaction in the oxidation of the side chain of sterol intermediates. The active form of vitamin D3 (calcitriol) binds to intracellular receptors that then function as transcription factors to modulate gene expression. Like the receptors for other steroid hormones and thyroid hormones, the vitamin D receptor has hormone-binding and DNA-binding domains. The vitamin D receptor forms a complex with another intracellular receptor, the retinoid-X receptor, and that heterodimer is what binds to DNA. In most cases studied, the effect is to activate transcription, but situations are also known in which vitamin D suppresses transcription. Calcitriol increases the serum calcium concentrations by: increasing GI absorption of phosphorus and calcium, increasing osteoclastic resorption, and increasing distal renal tubula... Vitamin D3, also called cholecalciferol, is one of the forms of vitamin D. Vitamin D3 is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus, in mineralization of bone, and for the assimilation of Vitamin A. It is structurally similar to steroids such as testosterone, cholesterol, and cortisol (although vitamin D3, itself, is a secosteroid). Vitamin D3 is a derivative of 7-dehydroxycholesterol formed by ultraviolet rays breaking the C9-C10 bond. It differs from ergocalciferol in having a single bond between C22 and C23 and lacking a methyl group at C24. Vitamin D3 can also come from dietary sources, such as beef liver, cheese, egg yolks, and fatty fish (PubChem). The first step involved in the activation of vitamin D3 is a 25-hydroxylation catalyzed by 25-hydroxylase in the liver and then by other enzymes. The mitochondrial sterol 27-hydroxylase catalyzes the first reaction in the oxidation of the side chain of sterol intermediates. The active form of vitamin D3 (calcitriol) binds to intracellular receptors that then function as transcription factors to modulate gene expression. Like the receptors for other steroid hormones and thyroid hormones, the vitamin D receptor has hormone-binding and DNA-binding domains. The vitamin D receptor forms a complex with another intracellular receptor, the retinoid-X receptor, and that heterodimer is what binds to DNA. In most cases studied, the effect is to activate transcription, but situations are also known in which vitamin D suppresses transcription. Calcitriol increases the serum calcium concentrations by (1) increasing GI absorption of phosphorus and calcium, (2) increasing osteoclastic resorption, and (3) increasing distal renal tubular reabsorption of calcium. Calcitriol appears to promote intestinal absorption of calcium through binding to the vitamin D receptor in the mucosal cytoplasm of the intestine. Subsequently, calcium is absorbed through the formation of a calcium-binding protein. Vitamin d, also known as colecalciferol or calciol, belongs to vitamin d and derivatives class of compounds. Those are compounds containing a secosteroid backbone, usually secoergostane or secocholestane. Thus, vitamin d is considered to be a secosteroid lipid molecule. Vitamin d is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Vitamin d can be found in a number of food items such as dumpling, vinegar, chocolate, and margarine, which makes vitamin d a potential biomarker for the consumption of these food products. Vitamin d can be found primarily in blood and urine. Vitamin d is a non-carcinogenic (not listed by IARC) potentially toxic compound. Vitamin d is a drug which is used for the treatment of vitamin d deficiency or insufficiency, refractory rickets (vitamin d resistant rickets), familial hypophosphatemia and hypoparathyroidism, and in the management of hypocalcemia and renal osteodystrophy in patients with chronic renal failure undergoing dialysis. also used in conjunction with calcium in the management and prevention of primary or corticosteroid-induced osteoporosis.

Cytidine
Cytidine is a nucleoside that is composed of the base cytosine linked to the five-carbon sugar D-ribose. Cytidine is a pyrimidine that besides being incorporated into nucleic acids, can serve as a substrate for the salvage pathway of pyrimidine nucleotide synthesis. It is a precursor of cytidine triphosphate (CTP) needed in the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) biosynthetic pathways. These variations probably reflect the species differences in cytidine deaminase, the enzyme that converts cytidine to uridine in the body. The transport of cytidine into the brains extracellular fluid, and then into neurons and glia, are essential prerequisites for cytidine to be utilized in the brain. An efficient mechanism mediating the brain uptake of circulating cytidine has not yet been demonstrated. The biosynthesis of PC, the most abundant phosphatide in the brain, via the Kennedy pathway requires phosphocholine and cytidine triphosphate (CTP), a cytidine nucleotide involved in the rate-limiting step. The enzyme that converts CTP to endogenous CDP-choline (CTP:phosphocholine cytidylyltransferase) is unsaturated at physiological brain CTP levels. APOBEC is a family of enzymes that has been discovered with the ability to deaminate cytidines on RNA or DNA. The human apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G protein (APOBEC3G, or hA3G), provides cells with an intracellular antiretroviral activity that is associated with the hypermutation of viral DNA through cytidine deamination. Indeed, hA3G belongs to a family of vertebrate proteins that contains one or two copies of a signature sequence motif unique to cytidine deaminases (CTDAs) (PMID: 16769123, 15780864, 16720547).

Nervonic acid
Nervonic acid is a long chain unsaturated fatty acid that is enriched in sphingomyelin. It consists of choline, sphingosine, phosphoric acid, and fatty acid. Nervonic acid may enhance the brain functions and prevent demyelination (Chemical Land21). Research shows that there is negative relationship between nervonic acid and obesity-related risk factors (PMID:16394593). Demyelination in adrenoleukodystrophy (ALD) is associated with an accumulation of very long chain saturated fatty acids stemming from a genetic defect in the peroxisomal beta oxidation system responsible for the chain shortening of these fatty acids. Sphingolipids from post mortem ALD brain have decreased levels of nervonic acid, 24:1(n-9), and increased levels of stearic acid, 18:0. (PMID:8072429).

3-Hydroxyisovaleric acid
3-Hydroxyisovaleric acid is a normal human metabolite excreted in the urine. It is a byproduct of the leucine degradation pathway. Production of 3-hydroxyisovaleric acid begins with the conversion of 3-methylcrotonyl-CoA into 3-methylglutaconyl-CoA in the mitochondria by the biotin-dependent enzyme methylcrotonyl-CoA carboxylase. Biotin deficiencies, certain lifestyle habits (smoking), or specific genetic conditions can reduce methylcrotonyl-CoA carboxylase activity. This reduction can lead to a buildup of 3-methylcrotonyl-CoA, which is converted into 3-hydroxyisovaleryl-CoA by the enzyme enoyl-CoA hydratase. Increased concentrations of 3-methylcrotonyl-CoA and 3-hydroxyisovaleryl-CoA can lead to a disruption of the esterified CoA:free CoA ratio, and ultimately to mitochondrial toxicity. Detoxification of these metabolic end products occur via the transfer of the 3-hydroxyisovaleryl moiety to carnitine forming 3-hydroxyisovaleric acid-carnitine or 3HIA-carnitine, which is then transferred across the inner mitochondrial membrane where 3-hydroxyisovaleric acid is released as the free acid (PMID: 21918059). 3-Hydroxyisovaleric acid has been found to be elevated in smokers and in subjects undergoing long-term anticonvulsant therapy with carbamazepine and/or phenytoin. These levels are elevated due to impairment of renal reclamation of biotin. Levels may also be increased from prolonged consumption of raw egg-whites (PMID: 16895887, 9523856, 15447901, 9176832) (OMIM: 210210, 253270, 600529, 253260, 246450, 210200, 238331). When present in sufficiently high levels, 3-hydroxyisovaleric acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of 3-hydroxyisovaleric acid are associated with at least a dozen inborn errors of metabolism, including 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, 3-methylglutaconic aciduria type I, biotinidase deficiency and isovaleric aciduria, dihydrolipoamide dehydrogenase deficiency, 3-methylcrotonyl-CoA carboxylase 1 deficiency, 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, late-onset multiple carboxylase deficiency, holocarboxylase synthetase deficiency, and 3-methylcrotonyl-CoA carboxylase 2 deficiency. 3-Hydroxyisovaleric acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. 3-Hydroxyisovaleric acid is a normal human metabolite excreted in the urine. Elevated levels of this compound are found in several inherited disorders such as Dihydrolipoamide dehydrogenase Deficiency, 3-Methylcrotonyl-CoA carboxylase 1 deficiency, 3-Hydroxy-3-methylglutaryl-CoA lyase deficiency (3-hydroxy-3-methylglutaryl -CoA lyase Deficiency, Biotinidase deficiency multiple carboxylase deficiency late-onset , Late onset multiple carboxylase deficiency, HolMcarboxylase synthetase deficiency, 3-Methylcrotonyl-CoA carboxylase 2 deficiency. 3-Hydroxyisovaleric acid is also elevated in smokers, in subjects undergoing long-term anticonvulsant therapy with carbamazepine and/or phenytoin.

The urinary excretion of 3-hydroxyisovaleric acid is early and sensitive indicator of biotin deficiency[1][2]. 3-Hydroxyisovaleric acid is a normal endogenous metabolite excreted in the urine.

Cysteinylglycine
Cysteinylglycine is a naturally occurring dipeptide. It is derived from the breakdown of glutathione (a tripeptide). In plasma, cysteinylglycine is in a reduced, oxidized and protein-bound form (aminothiol) and interact via redox and disulphide exchange reactions, in a dynamic system referred to as redox thiol status. (PMID 8642471) Spermatozoa of sub fertile men contain significantly higher thiol concentrations as compared with those of fertile men. The detrimental effect on embryo quality of a high homocysteine (Hcy, another member of the thiol group) concentration in the ejaculate and in follicular fluid is intriguing and may suggest that Hcy is inversely associated with fertility outcome. (PMID 16556671) Rheumatoid arthritis (RA) is a chronic inflammatory disease which involves the synovial membrane of multiple diarthroidal joints causing damage to cartilage and bones. The damage process seems to be related to an overproduction of oxygen reactive species inducing an oxidative perturbation with an increase in some oxidized forms (disulfides and protein mixed disulfides) and a decrease in free thiols. (PMID 15895891) Imipenem (thienamycin formamidine), is a broad-spectrum beta-lactam antibiotic, always used in combination with cilastatin in order to avoid the premature breakdown of imipenem by renal tubular dipeptidase. As this dipeptidase also hydrolyzes the glutathione metabolite cysteinylglycine, the therapeutic association of imipenem and cilastatin causes plasma levels of cysteinylglycine to increase significantly, while cysteine levels are decreased and homocysteine levels are unaffected. Therefore, antibiotic treatment using imipenem-cilastatin induces important metabolic changes that should not remain unrecognized. (PMID 15843241) [HMDB].

Guanidinosuccinic acid
Guanidinosuccinic acid (GSA) has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). It is one of the earliest uremic toxins isolated and its toxicity identified. Its metabolic origins show that it arose from the oxidation of argininosuccinic acid (ASA) by free radicals. The stimulus for this oxidation, occurring optimally in the presence of the failed kidney, is the rising level of urea which, through enzyme inhibition, results in a decline in hepatic levels of the semi-essential amino acid, arginine. It is further noted that concentrations of GSA in both serum and urine decline sharply in animals and humans exposed to the essential amino acid, methionine. Uremic patients suffer from a defective ability to generate methyl groups due to anorexia, dietary restrictions and renal protein leakage. This leads to the accumulation of homocysteine, a substance known to produce vascular damage. Even in healthy subjects intake of choline together with methionine is insufficient to satisfy total metabolic requirements for methyl groups. In end-stage renal disease, therefore, protein restriction contributes to the build-up of toxins in uremia. Replacement using specific amino acid mixtures should be directed toward identified deficiencies and adequacy monitored by following serum levels of the related toxins, in this case GSA and homocysteine.

Tolmetin
Tolmetin is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory agent (anti-inflammatory agents, NON-steroidal) similar in mode of action to indomethacin. [PubChem]The mode of action of tolmetin is not known. However, studies in laboratory animals and man have demonstrated that the anti-inflammatory action of tolmetin is not due to pituitary-adrenal stimulation. Tolmetin inhibits prostaglandin synthetase in vitro and lowers the plasma level of prostaglandin E in man. This reduction in prostaglandin synthesis may be responsible for the anti-inflammatory action. Tolmetin does not appear to alter the course of the underlying disease in man.

all-trans-Retinoic acid
all-trans-Retinoic acid is an isomer of retinoic acid, the oxidized form of vitamin A. Retinoic acid functions in determining position along embryonic anterior/posterior axis in chordates. It acts through Hox genes, which ultimately controls anterior/posterior patterning in early developmental stages (PMID:17495912). It is an important regulator of gene expression during growth and development, and in neoplasms. As a drug, all-trans-retinoic acid is known as tretinoin. Tretinoin is derived from maternal vitamin A and is essential for normal growth and embryonic development. An excess of tretinoin can be teratogenic. Tretinoin is used in the treatment of psoriasis, acne vulgaris, and several other skin diseases. It has also been approved for use in promyelocytic leukemia (leukemia, promyelocytic, acute).

Diaminopimelic acid
Diaminopimelic acid or DAPA is a lysine-like amino acid derivative that is a key component of the bacterial cell wall. DAPA is incorporated or integrated into peptidoglycan of gram negative bacteria and is the attachment point for Brauns lipoprotein (BLP or Murein Lipoprotein). BLP is found in gram-negative cell walls and is one of the most abundant membrane proteins. BLP is bound at its C-terminal end (a lysine) by a covalent bond to the peptidoglycan layer (specifically to diaminopimelic acid molecules) and is embedded in the outer membrane by its hydrophobic head (a cysteine with lipids attached). BLP tightly links the two layers and provides structural integrity to the bacterial outer membrane. Diaminopimelic acid can be found in human urine or feces due to the lysis or enzymatic breakdown of gram negative gut microbes. Acquisition and generation of the data is financially supported in part by CREST/JST. 2,6-Diaminoheptanedioic acid is an endogenous metabolite.
D-Tartaric acid
DL-Tartaric acid is a non-racemic mixture of L- and D-tartaric acids with antioxidant activities[1][2].
Prostaglandin E2
The naturally occurring prostaglandin E2 (PGE2) is known in medicine as dinoprostone, and it is the most common and most biologically active of the mammalian prostaglandins. It has important effects during labour and also stimulates osteoblasts to release factors which stimulate bone resorption by osteoclasts (a type of bone cell that removes bone tissue by removing the bones mineralized matrix). PGE2 is also the prostaglandin that ultimately induces fever. PGE2 has been shown to increase vasodilation and cAMP production, enhance the effects of bradykinin and histamine, and induce uterine contractions and platelet aggregation. PGE2 is also responsible for maintaining the open passageway of the fetal ductus arteriosus, decreasing T-cell proliferation and lymphocyte migration, and activating the secretion of IL-1α and IL-2. PGE2 exhibits both pro- and anti-inflammatory effects, particularly on dendritic cells (DC). Depending on the nature of maturation signals, PGE2 has different and sometimes opposite effects on DC biology. PGE2 exerts an inhibitory action, reducing the maturation of DC and their ability to present antigen. PGE2 has also been shown to stimulate DC and promote IL-12 production when given in combination with TNF-alpha. PGE2 is an environmentally bioactive substance. Its action is prolonged and sustained by other factors especially IL-10. It modulates the activities of professional DC by acting on their differentiation, maturation, and their ability to secrete cytokines. PGE2 is a potent inducer of IL-10 in bone marrow-derived DC (BM-DC). PGE2-induced IL-10 is a key regulator of the BM-DC pro-inflammatory phenotype (PMID:16978535). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent and are able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis through receptor-mediated G-protein linked signalling pathways. Dinoprostone is a naturally occurring prostaglandin E2 (PGE2) and the most common and most biologically active of the mammalian prostaglandins.

Calcitriol
The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (calcifediol). Its production is stimulated by low blood calcium levels and parathyroid hormone.

Etodolac
Etodolac is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties. Its therapeutic effects are due to its ability to inhibit prostaglandin synthesis. It is indicated for relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. Similar to other NSAIDs, the anti-inflammatory effects of etodolac result from inhibition of the enzyme cycooxygenase (COX). This decreases the synthesis of peripheral prostaglandins involved in mediating inflammation. Etodolac binds to the upper portion of the COX enzyme active site and prevents its substrate, arachidonic acid, from entering the active site. Etodolac was previously thought to be a non-selective COX inhibitor, but it is now known to be 5 – 50 times more selective for COX-2 than COX-1. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.

Arachidonic acid
Arachidonic acid is a polyunsaturated, essential fatty acid that has a 20-carbon chain as a backbone and four cis-double bonds at the C5, C8, C11, and C14 positions. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is synthesized from dietary linoleic acid. Arachidonic acid mediates inflammation and the functioning of several organs and systems either directly or upon its conversion into eicosanoids. Arachidonic acid in cell membrane phospholipids is the substrate for the synthesis of a range of biologically active compounds (eicosanoids) including prostaglandins, thromboxanes, and leukotrienes. These compounds can act as mediators in their own right and can also act as regulators of other processes, such as platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function. Arachidonic acid can be metabolized by cytochrome p450 (CYP450) enzymes into 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acids (EETs), their corresponding dihydroxyeicosatrienoic acids (DHETs), and 20-hydroxyeicosatetraenoic acid (20-HETE). The production of kidney CYP450 arachidonic acid metabolites is altered in diabetes, pregnancy, hepatorenal syndrome, and in various models of hypertension, and it is likely that changes in this system contribute to the abnormalities in renal function that are associated with many of these conditions. Phospholipase A2 (PLA2) catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (PMID: 12736897, 12736897, 12700820, 12570747, 12432908). The beneficial effects of omega-3 fatty acids are believed to be due in part to selective alteration of arachidonate metabolism that involves cyclooxygenase (COX) enzymes (PMID: 23371504). 9-Oxononanoic acid (9-ONA), one of the major products of peroxidized fatty acids, was found to stimulate the activity of phospholipase A2 (PLA2), the key enzyme to initiate the arachidonate cascade and eicosanoid production (PMID: 23704812). Arachidonate lipoxygenase (ALOX) enzymes metabolize arachidonic acid to generate potent inflammatory mediators and play an important role in inflammation-associated diseases (PMID: 23404351).

4,4'-Methylenedianiline
4,4’-Methylenedianiline (MDA) is an industrial chemical that is produced and used industrially as a precursor to polyamides, epoxy resins, and polyurethane foams (PMID: 20621954). It is a primary aromatic amine, belonging to the family of compounds known as Diphenylmethanes. Diphenylmethanes are compounds consisting of methane with two of the hydrogen atoms replaced by phenyl groups. MDA is used mainly as a precursor to 4,4 ́-methylene diphenyl diisocyanate (MDI), which is a precursor to many polyurethane foams. To generate MDI, which is a highly reactive isocyanate, MDA is treated with phosgene. Workers exposed to MDI may develop sensitization, leading to occupational asthma. MDI is metabolized in the body and secreted in the urine as MDA, Therefore MDA is a urinary biomarker of MDI exposure. On its own, MDA is a known animal carcinogen, and human hepatotoxin. MDA produces genotoxic effects by forming DNA adducts in the liver and inducing DNA damage to hepatocytes (PMID: 32038824). The Occupational Safety and Health Administration has set a permissible exposure limit at 0.01 ppm over an eight-hour time-weighted average, and a short-term exposure limit at 0.10 ppm.

Rivastigmine
Rivastigmine is only found in individuals that have used or taken this drug. It is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimers type. Rivastigmine is a cholinesterase inhibitor that inhibits both butyrylcholinesterase and acetylcholinesterase.Rivastigmine is a carbamate derivative that is structurally related to physostigmine, but not to donepezil and tacrine. The precise mechanism of rivastigmine has not been fully determined, but it is suggested that rivastigmine binds reversibly with and inactivates chlolinesterase (eg. acetylcholinesterase, butyrylcholinesterase), preventing the hydrolysis of acetycholine, and thus leading to an increased concentration of acetylcholine at cholinergic synapses. The anticholinesterase activity of rivastigmine is relatively specific for brain acetylcholinesterase and butyrylcholinesterase compared with those in peripheral tissues.

Tenofovir
Tenofovir is only found in individuals that have used or taken this drug. Tenofovir, marketed by Gilead Sciences under the trade name Viread®, belongs to a class of antiretroviral drugs known as nucleotide analogue reverse transcriptase inhibitors (nRTIs), which block reverse transcriptase, an enzyme crucial to viral production in HIV-infected people. [Wikipedia]Tenofovir inhibits the activity of HIV reverse transcriptase by competing with the natural substrate deoxyadenosine 5’-triphosphate and, after incorporation into DNA, by DNA chain termination. Specifically, the drugs are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain. However, unlike the natural deoxynucleotides substrates, NRTIs and NtRTIs (nucleoside/tide reverse transcriptase inhibitors) lack a 3-hydroxyl group on the deoxyribose moiety. As a result, following incorporation of an NRTI or an NtRTI, the next incoming deoxynucleotide cannot form the next 5-3 phosphodiester bond needed to extend the DNA chain. Thus, when an NRTI or NtRTI is incorporated, viral DNA synthesis is halted, a process known as chain termination. All NRTIs and NtRTIs are classified as competitive substrate inhibitors.

Pentoxifylline
Pentoxifylline is only found in individuals that have used or taken this drug. It is a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. It improves blood flow by increasing erythrocyte and leukocyte flexibility. It also inhibits platelet aggregation. Pentoxifylline modulates immunologic activity by stimulating cytokine production. [PubChem]Pentoxifylline inhibits erythrocyte phosphodiesterase, resulting in an increase in erythrocyte cAMP activity. Subsequently, the erythrocyte membrane becomes more resistant to deformity. Along with erythrocyte activity, pentoxifylline also decreases blood viscosity by reducing plasma fibrinogen concentrations and increasing fibrinolytic activity. It is also a non selective adenosine receptor antagonist.

Dimethylarsinic acid
Dimethylarsinic acid, also known as cacodylic acid, is formally rated as possibly a carcinogenic (IARC 2B), potentially toxic compound. Derivatives of cacodylic acid, cacodylates, were frequently used as herbicides. For example, Agent Blue, one of the chemicals used during the Vietnam War, is a mixture of cacodylic acid and sodium cacodylate. Sodium cacodylate is frequently used as a buffering agent in the preparation and fixation of biological samples for transmission electron microscopy. Dimethylarsinic acid is highly toxic by ingestion, inhalation, or skin contact. Once thought to be a byproduct of inorganic arsenic detoxification, it is now believed to have serious health consequences of its own. It has been shown to be teratogenic in rodents, most often causing cleft palate but also fetal fatality at high doses. It has been shown to be genotoxic in human cells, causing apoptosis and also decreased DNA production and shorter DNA strands. While not itself a strong carcinogen, dimethylarsinic acid does promote tumours in the presence of carcinogens in organs such as the kidneys and liver (Wikipedia). Cacodylic acid is the chemical compound with the formula (CH3)2AsO2H. Derivatives of cacodylic acid, cacodylates, were frequently used as herbicides. For example, "Agent Blue," one of the chemicals used during the Vietnam War, is a mixture of cacodylic acid and sodium cacodylate. Sodium cacodylate is frequently used as a buffering agent in the preparation and fixation of biological samples for transmission electron microscopy.

p-Cresol
para-Cresol, also 4-methylphenol, is an organic compound with the formula CH3C6H4(OH). P-cresol is a cresol that consists of toluene substituted by a hydroxy group at position 4. It is a metabolite of aromatic amino acid metabolism produced by intestinal microflora in humans and animals. It has a role as a uremic toxin, a human metabolite and an Escherichia coli metabolite. It is a colourless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of o-cresol and m-cresol. It is a partially lipophilic moiety which strongly binds to plasma protein (close to 100\\%) under normal conditions. p-Cresol is metabolized through conjugation, mainly sulphation and glucuronization, but removal of the unconjugated p-cresol is, at least in part, via the urine. Therefore it is not surprising that this compound, together with several other phenoles, is retained when the kidneys fail. P-Cresol is an end-product of protein breakdown, and an increase of the nutritional protein load in healthy individuals results in enhanced generation and urinary excretion. The serum p-cresol concentration in uremic patients can be decreased by changing to a low-protein diet. p-Cresol is one of the metabolites of the amino acid tyrosine, and to a certain extent also of phenylalanine, which are converted to 4-hydroxyphenylacetic acid by intestinal bacteria, before being decarboxylated to p-cresol (putrefaction). The main contributing bacteria are aerobes (mainly enterobacteria), but to a certain extent also anaerobes play a role (mainly Clostridium perfringens). In uremia, modifications in the intestinal flora result in the specific overgrowth of bacteria that are specific p-cresol producers. The administration of antibiotics reduces urinary excretion of p-cresol, as a result of the liquidation of the producing bacteria. Environmental factors might also contribute. The liver cytochrome P450 metabolizes toluene to benzyl alcohol, but also to o-cresol and p-cresol. Toluene is not only used industrially, but it is also the most widely abusively inhaled solvent. Furthermore, p-cresol is a metabolite of menthofuran, one of the metabolites of R-(+)-pulegone, which is found in extracts from the plants Mentha pulegium and Hedeoma pulegioides, commonly known as pennyroyal oil and pennyroyal tea. These extracts are popular as unconventional herbal therapeutic agents and are applied as abortiva, diaphoretics, emmenagogues, and psychedelic drugs. Pennyroyal oil is extensively used for its pleasant mint-like smell in the flavoring industry. The toxicity of pennyroyal oil and menthofuran is well known. Another compound used in traditional medicine, especially in Japan, which is a precursor of p-cresol is wood tar creosote. p-Cresol has been reported to affect several biochemical, biological and physiological functions: (i) it diminishes the oxygen uptake of rat cerebral cortex slices; (ii) it increases the free active drug concentration of warfarin and diazepam; (iii) it has been related to growth retardation in the weanling pig; (iv) it alters cell membrane permeability, at least in bacteria; (v) it induces LDH leakage from rat liver slices; (vi) it induces susceptibility to auditive epileptic crises; and (vii) it blocks cell K+ channels. (PMID:10570076). p-Cresol is a uremic toxin that is at least partially removed by peritoneal dialysis in haemodialysis patients, and has been involved in the progression of renal failure (PMID:11169029). At concentrations encountered during uremia, p-cresol inhibits phagocyte function and decreases leukocyte adhesion to cytokine-stimulated endothelial cells. (PMID:14681860). p-Cresol can be found in Bacteroides, Bifidobacterium, Clostridium, Enterobacter and Lactobacillus (PMID:2394806; PMID:30208103). As a volatile organic compound, it has been identified as a fecal biomarker of Clostridium difficile infection (PMID:30986230). Present in blackcurrant buds, asparagus, cooked cured pork, black tea, fermented tea, yellow passion fruit juice, malt, peated malt, kumazasa (Sasa albo-marginata), lambs lettuce, squid and cuttlefish. Flavouring ingredient. 4-Methylphenol is found in many foods, some of which are animal foods, cereals and cereal products, tamarind, and tarragon.
Phenylacetylglutamine
Phenylacetylglutamine is a product formed from the conjugation of phenylacetate and glutamine. Technically, it is the amino acid acetylation product of phenylacetate (or phenylbutyrate after beta-oxidation). Phenylacetylglutamine is a normal constituent of human urine, but other mammals such as the dog, cat, rat, monkey, sheep, and horse do not excrete this compound. Phenylacetyl-CoA and L-glutamine react to form phenylacetylglutamine and coenzyme A. The enzyme (glutamine N-acetyl transferase) that catalyzes this reaction has been purified from human liver mitochondria and shown to be a polypeptide species distinct from glycine-N-acyltransferase. Phenylacetylglutamine is a major nitrogenous metabolite that accumulates in uremia (PMID: 2791363, 8972626). It has been shown that over 50\\\% of urine phenylacetylglutamine may be derived from kidney conjugation of free plasma phenylacetic acid and/or from the kidneys preferential filtration of conjugated phenylacetic acid (PMID: 6420430). Phenylacetylglutamine is a microbial metabolite found in Christensenellaceae, Lachnospiraceae and Ruminococcaceae (PMID: 26241311). Phenylacetylglutamine is a product formed by the conjugation of phenylacetate and glutamine. Technically it is the amino acid acetylation product of phenylacetate (or phenylbutyrate after beta-oxidation). Phenylacetylglutamine is a normal constituent of human urine, but other mammals including the dog, cat, rat, monkey, sheep and horse do not excrete this compound. Phenylacetyl CoA and glutamine react to form phenylacetyl glutamine and Coenzyme A. The enzyme (Glutamine N-acetyl transferase) that catalyzes this reaction has been purified from human liver mitochondria and shown to be a distinct polypeptide species from glycine-N-acyltransferase. Phenylacetylglutamine is a major nitrogenous metabolite that accumulates in uremia. (PMID: 2791363; PMID: 8972626).

Emtricitabine
Emtricitabine is only found in individuals that have used or taken this drug. It is a nucleoside reverse transcriptase inhibitor (NRTI) for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults. Emtricitabine works by inhibiting reverse transcriptase (RT), an enzyme that allows the virus to multiply by copying HIV RNA into new viral DNA. The drug competes with the reverse transcriptases natural substrate deoxycytidine 5-triphosphate and also becomes incorporated into viral DNA. This is a result of emtricitabine being a synthetic nucleoside analogue of cytidine. It is phosphorylated by cellular enzymes to form emtricitabine 5-triphosphate which competes with the natural substrate deoxycytidine 5-triphosphate and becomes incorporated into nascent viral DNA, resulting in early chain termination. By inhibiting HIV-1 reverse transcriptase, emtricitabine can help to lower the amount of HIV (viral load) in a patients body and can indirectly increase the number of immune system cells (T cells or CD4+ T-cells). Both of these changes are associated with healthier immune systems and a decreased likelihood of serious illness. Emtricitabine is always used in conjunction with other HIV medicine to treat people with HIV infection.

Norvaline
Norvaline is a non-proteinogenic branched-chain amino acid with the chemical formula C5H11NO2, isomeric with valine. It has previously been reported to be a natural component of an antifungal peptide of Bacillus subtilis. Norvaline and other modified branched chain amino acids have received attention in recent studies, as they appear to be incorporated in some recombinant proteins found in E. coli. This amino acid is often made synthetically. DL-Norvaline, a derivative of L-norvaline, L-norvaline is a non-competitive inhibitor of arginase. DL-Norvaline, a derivative of L-norvaline, L-norvaline is a non-competitive inhibitor of arginase.
Toremifene
Toremifene is only found in individuals that have used or taken this drug. It is a first generation nonsteroidal selective estrogen receptor modulator (SERM) that is structurally related to tamoxifen. Like tamoxifen, it is an estrogen agonist for bone tissue and cholesterol metabolism but is antagonistic on mammary and uterine tissue. [PubChem]Toremifene is a nonsteroidal triphenylethylene derivative. Toremifene binds to estrogen receptors and may exert estrogenic, antiestrogenic, or both activities, depending upon the duration of treatment, animal species, gender, target organ, or endpoint selected. The antitumor effect of toremifene in breast cancer is believed to be mainly due to its antiestrogenic effects, in other words, its ability to compete with estrogen for binding sites in the cancer, blocking the growth-stimulating effects of estrogen in the tumor. Toremifene may also inhibit tumor growth through other mechanisms, such as induction of apoptosis, regulation of oncogene expression, and growth factors.

Laricitrin
Laricitrin, also known as 3-O-methylmyricetin or 3,4,5,5,7-pentahydroxy-3-methoxyflavone, belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, laricitrin is considered to be a flavonoid lipid molecule. Laricitrin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. BioTransformer predicts that laricitrin is a product of isorhamnetin metabolism via a hydroxylation-of-benzene-ortho-to-edg reaction catalyzed by the CYP1A2, CYP2C8, CYP2C9, and CYP3A4 enzymes (PMID: 30612223).

Decanoylcarnitine (C10)
Decanoylcarnitine is a member of the class of compounds known as acylcarnitines. More specifically, it is a decanoic acid ester of carnitine. Acylcarnitines were first discovered in the 1940s (PMID: 13825279 ). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Decanoylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine decanoylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494 ). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. In particular decanoylcarnitine is elevated in the blood or plasma of individuals with obesity in adolescence (PMID: 26910390 ). It is also decreased in the blood or plasma of individuals with adolescent idiopathic scoliosis (PMID: 26928931 ). Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279 ). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews]. Acylcarnitine useful in the diagnosis of fatty acid oxidation disorders and differentiation between biochemical phenotypes of medium-chain acyl-CoA dehydrogenase (MCAD) deficiency deficiencyoxidation disorders.(PMID: 12385891) [HMDB]

Glycolaldehyde
Glycolaldehyde, also known as hydroxyacetaldehyde or methylol formaldehyde, is a member of the class of compounds known as short-chain aldehydes. Short-chain aldehydes are an aldehyde with a chain length containing between 2 and 5 carbon atoms. Glycolaldehyde is soluble (in water) and a very weakly acidic compound (based on its pKa). Glycolaldehyde can be found in a number of food items such as acorn, elderberry, dandelion, and conch, which makes glycolaldehyde a potential biomarker for the consumption of these food products. Glycolaldehyde can be found primarily in human neuron tissue. Glycolaldehyde exists in all living organisms, ranging from bacteria to humans. In humans, glycolaldehyde is involved in the vitamin B6 metabolism. Glycolaldehyde is also involved in hypophosphatasia, which is a metabolic disorder. Glycolaldehyde is the organic compound with the formula HOCH2-CHO. It is the smallest possible molecule that contains both an aldehyde group and a hydroxyl group. It is a highly reactive molecule that occurs both in the biosphere and in the interstellar medium. It is normally supplied as a white solid. Although it conforms to the general formula for carbohydrates, Cn(H2O)n, it is not generally considered to be a saccharide . Glycolaldehyde (HOCH2-CH=O, IUPAC name 2-hydroxyethanal) is a type of diose (2-carbon monosaccharide). Glycolaldehyde is readily converted to acetyl coenzyme A. It has an aldehyde and a hydroxyl group. However, it is not actually a sugar, because there is only one hydroxyl group. Glycolaldehyde is formed from many sources, including the amino acid glycine and from purone catabolism. It can form by action of ketolase on fructose 1,6-bisphosphate in an alternate glycolysis pathway. This compound is transferred by thiamin pyrophosphate during the pentose phosphate shunt.
Glycolithocholate
Lithocholic acid glycine conjugate is an acyl glycine and a bile acid-glycine conjugate. is an acyl glycine and a bile acid-glycine conjugate. It is a secondary bile acid produced by the action of enzymes existing in the microbial flora of the colonic environment. In hepatocytes, both primary and secondary bile acids undergo amino acid conjugation at the C-24 carboxylic acid on the side chain, and almost all bile acids in the bile duct therefore exist in a glycine conjugated form (PMID: 16949895). Bile acids are steroid acids found predominantly in the bile of mammals. The distinction between different bile acids is minute, depending only on the presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g. membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135).

PG(16:0/18:1(9Z))
PG(16:0/18:1(9Z)) is a phosphatidylglycerol or glycerophospholipid (PG or GP). It is a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PG(16:0/18:1(9Z)), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of oleic acid at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Phosphatidylglycerol is present at a level of 1-2\\% in most animal tissues, but it can be the second most abundant phospholipid in lung surfactant at up to 11\\% of the total. It is well established that the concentration of phosphatidylglycerol increases during fetal development. Phosphatidylglycerol may be present in animal tissues merely as a precursor for diphosphatidylglycerol (cardiolipin). Phosphatidylglycerol is formed from phosphatidic acid by a sequence of enzymatic reactions that proceeds via the intermediate, cytidine diphosphate diacylglycerol (CDP-diacylglycerol). Bioynthesis proceeds by condensation of phosphatidic acid and cytidine triphosphate with elimination of pyrophosphate via the action of phosphatidate cytidyltransferase (or CDP-synthase). CDP-diacylglycerol then reacts with glycerol-3-phosphate via phosphatidylglycerophosphate synthase to form 3-sn-phosphatidyl-1-sn-glycerol 3-phosphoric acid, with the release of cytidine monophosphate (CMP). Finally, phosphatidylglycerol is formed by the action of specific phosphatases. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PGs have a net charge of -1 at physiological pH and are found in high concentration in mitochondrial membranes and as components of pulmonary surfactant. PG also serves as a precursor for the synthesis of cardiolipin. PG is synthesized from CDP-diacylglycerol and glycerol-3-phosphate. PG(16:0/18:1(9Z)) is a phosphatidylglycerol. Phosphatidylglycerols consist of a glycerol 3-phosphate backbone esterified to either saturated or unsaturated fatty acids on carbons 1 and 2. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PG(16:0/18:1(9Z)), in particular, consists of one hexadecanoyl chain to the C-1 atom, and one 9Z-octadecenoyl to the C-2 atom. In E. coli glycerophospholipid metabolism, phosphatidylglycerol is formed from phosphatidic acid (1,2-diacyl-sn-glycerol 3-phosphate) by a sequence of enzymatic reactions that proceeds via two intermediates, cytidine diphosphate diacylglycerol (CDP-diacylglycerol) and phosphatidylglycerophosphate (PGP, a phosphorylated phosphatidylglycerol). Phosphatidylglycerols, along with CDP-diacylglycerol, also serve as precursor molecules for the synthesis of cardiolipin, a phospholipid found in membranes.
Nicotinic acid adenine dinucleotide
Nicotinic acid adenine dinucleotide, also known as deamido-NAD or NAAD, belongs to the class of organic compounds known as (5->5)-dinucleotides. These are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. NAAD is possibly soluble (in water) and a strong basic compound (based on its pKa). NAAD exists in all living species, ranging from bacteria to humans. L-Glutamine and NAAD can be converted into L-glutamic acid and NAD; which is catalyzed by the enzyme glutamine-dependent nad(+) synthetase. In humans, NAAD is involved in the nicotinate and nicotinamide metabolism pathway. NAAD is also involved in the metabolic disorder called succinic semialdehyde dehydrogenase deficiency. Outside of the human body, NAAD has been detected, but not quantified in, several different foods, such as japanese walnuts, cauliflowers, sparkleberries, komatsuna, and macadamia nut (m. tetraphylla). This could make NAAD a potential biomarker for the consumption of these foods. NAAD is the product of the degradation of Nicotinic acid adenine dinucleotide phosphate (NAADP) by a Ca2+-sensitive phosphatase. NAADP is a Ca2+-mobilizing second messenger which is synthesized, in response to extracellular stimuli, via the base-exchange reaction by an ADP-ribosyl cyclase (ARC) family members (such as CD38). NAADP binds to and opens Ca2+ channels on intracellular organelles, thereby increasing the intracellular Ca2+ concentration which, in turn, modulates a variety of cellular processes. Structurally, NAADP it is a dinucleotide that only differs from the house-keeping enzyme cofactor, NADP, by a hydroxyl group (replacing the nicotinamide amino group) and yet this minor modification converts it into the most potent Ca2+-mobilizing second messenger yet described. NAADP may also be broken down to 2-phosphoadenosine diphosphoribose (ADPRP) by CD38 or reduced to NAADPH. Deamido-nad(+), also known as deamidonicotinamide adenine dinucleoetide, is a member of the class of compounds known as (5->5)-dinucleotides (5->5)-dinucleotides are dinucleotides where the two bases are connected via a (5->5)-phosphodiester linkage. Deamido-nad(+) is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Deamido-nad(+) can be found in a number of food items such as garden tomato, sea-buckthornberry, pitanga, and japanese walnut, which makes deamido-nad(+) a potential biomarker for the consumption of these food products. Deamido-nad(+) exists in all living species, ranging from bacteria to humans. In humans, deamido-nad(+) is involved in few metabolic pathways, which include glutamate metabolism, homocarnosinosis, and nicotinate and nicotinamide metabolism. Deamido-nad(+) is also involved in few metabolic disorders, which include 2-hydroxyglutric aciduria (D and L form), 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency, hyperinsulinism-hyperammonemia syndrome, and succinic semialdehyde dehydrogenase deficiency.

N-Carbamoylsarcosine
N-Carbamoylsarcosine is an intermediate in arginine and proline metabolism. It is also involved in a metabolic pathway for the degradation of creatinine. In this pathway, creatinine is not hydrolyzed back to creatine. Instead, it is deaminated to N-methylhydantoin, releasing an amonia molecule, by the action of creatinine deaminase (also known as creatinine iminohydrolase). N-methylhydantoin is then hydrolyzed to N-carbamoylsarcosine, by the action of N-methylhydantoin amidohydrolase, at the expense of one ATP molecule. N-carbamoylsarcosine is deaminated further to sarcosine by N-carbamoylsarcosine amidohydrolase, releasing a second ammonia molecule. In the last step of this pathway, sarcosine is hydrolyzed to glycine and formaldehyde, by either sarcosine dehydrogenase or sarcosine oxidase.

Calcidiol
Calfcifediol is a prehormone that is produced in the liver by hydroxylation of vitamin D3 (cholecalciferol) by the enzyme cholecalciferol 25-hydroxylase. Calcifediol is then converted in the kidneys into calcitriol (1,25-(OH)2D3), a secosteroid hormone that is the active form of vitamin D. It can also be converted into 24-hydroxycalcidiol in the kidneys via 24-hydroxylation. [Wikipedia]. 25-Hydroxycholecalciferol is found in many foods, some of which are green zucchini, green bell pepper, red bell pepper, and other animal fat. The major circulating metabolite of vitamin D3 (calciferon). It is produced in the liver and is the best indicator of the bodys vitamin D stores.

Coproporphyrin I
Coproporphyrin I is a porphyrin metabolite arising from heme synthesis. Porphyrins are pigments found in both animal and plant life. Coproporphyrin I is a tetrapyrrole dead-end product from the spontaneous oxidation of the methylene bridges of coproporphynogen, arising from heme synthesis and secreted in feces and urine. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Porphyria is a pathological state characterised by abnormalities of porphyrin metabolism and results in the excretion of large quantities of porphyrins in the urine and in extreme sensitivity to light. A large number of factors are capable of increasing porphyrin excretion, owing to different and multiple causes and etiologies: 1) the main site of the chronic hepatic porphyria disease process concentrates on the liver, 2) a functional and morphologic liver injury is almost regularly associated with this chronic porphyria, 3) the toxic form due to occupational and environmental exposure takes mainly a subclinical course. Hepatic factors includes disturbance in coproporphyrinogen metabolism, which results from inhibition of coproporphyrinogen oxidase as well as from the rapid loss from, and diminished utilization of coproporphyrinogen in the hepatocytes, which may also explain why coproporphyrin, its autoxidation product, predominates physiologically in the urine; decreased biliary excretion of coproporphyrin leading to a compensatory urinary excretion, so that the coproporphyrin ring isomer ratio (1:III) becomes a sensitive index for impaired liver function and intrahepatic cholestasis; and disturbed activity of hepatic uroporphyrinogen decarboxylase. In itself, secondary coproporphyrinuria is not associated with porphyria symptoms of a hepatologic-gastroenterologic, neurologic, or dermatologic order, even though coproporphyrinuria can occur with such symptoms. (PMID: 3327428). Coproporhyrin I is a porphyrin metabolite arising from heme synthesis. Porphyrins are pigments found in both animal and plant life.
Lipoxin B4
Lipoxins (LXs) and aspirin-triggered lipoxin (ATL) are trihydroxytetraene-containing eicosanoids generated from arachidonic acid that are distinct in structure, formation, and function from the many other proinflammatory lipid-derived mediators. These endogenous eicosanoids have now emerged as founding members of the first class of lipid/chemical mediators involved in the resolution of the inflammatory response. Lipoxin A4 (LXA4), ATL, and their metabolic stable analogs elicit cellular responses and regulate leukocyte trafficking in vivo by activating the specific receptor, ALX. Many of the eicosanoids derived from arachidonic acid (AA2), including prostaglandins (PGs) and leukotrienes (LTs), play important roles as local mediators exerting a wide range of actions relevant in immune hypersensitivity and inflammation. However, recent observations indicate that other agents derived from the lipoxygenase (LO) pathways are formed and play a key role in initiating the resolution of acute inflammation. This phenomenon is an active process that is governed by specific lipid mediators and involves a series of well-orchestrated temporal events. Thus, potent locally released mediators serve as checkpoint controllers of inflammation. In addition to the well-appreciated ability of aspirin to inhibit PGs, aspirin also acetylates cyclooxygenase (COX)-2, triggering the formation of a 15-epimeric form of lipoxins, termed aspirin-triggered LXA4 (ATL). These eicosanoids (i.e. LXA4 and ATL) with a unique trihydroxytetraene structure function as stop signals in inflammation and actively participate in dampening host responses to bring the inflammation to a close, namely, resolution. LXA4 and ATL elicit the multicellular responses via a specific G protein-coupled receptor (GPCR) termed ALX that has been identified in human (PMID: 16968948, 11478982).

Methylarsonate
Methylarsonate is used as a contact herbicide in either the monosodium or disodium salt form. It goes by the trade names Weed-E-Rad, Ansar 170 H.C., Ansar 529 H.C., DiTac and others. Methylarsonate is considered only slightly toxic, having an oral LD50 of 2200 mg/Kg for rats. The inhalation risk is greater with LD50 Rats >20 mg. Long term studies with people exposed to organoarsenicals has shown an increased risk of skin cancer (Spiewak, 2001), lung cancer and some liver cancers, although some recent studies have shown some arsenic containing compounds (specifically Arsine trioxide) may have anticarcinogenic properties (Wang, 2001). In mammals, Methylarsonate is also an intermediate in the detoxification of inorganic arsenic. In the arsenate detoxification I pathway, arsenite reacts with S-adenosyl-L-methionine to produce methylarsonate and S-adenosyl-L-homocysteine. Arsenite methyltransferase catalyzes this reaction. Methylarsonate then reacts with 2 glutathione molecules to produce glutathione disulfide and methylarsonite. This reaction is catalyzed by methylarsonate reductase. Methylarsonate is an organic arsenic compound with adverse effects similar to those of arsenic trioxide. Arsenic is found in the environment primarily as arsenate and arsenite species. Arsenate is reduced to arsenite by arsenate reductase and can be subsequently methylated to Methylarsonate. This is then reduced and methylated to Dimethylarsinate, which can excreted and is considerably less toxic to the organism than any of the previous intermediate compounds. Methylarsonate was formerly included in some vitamin and mineral preparations. It was once used to treat tuberculosis, chorea, and other affections in which the cacodylates were used.

Pamidronate
Pamidronate is only found in individuals that have used or taken this drug.Pamidronate, marketed as pamidronate disodium pentahydrate under the brand name Aredia, is a bisphosphonate. [Wikipedia]The mechanism of action of pamidronate is inhibition of bone resorption. Pamidronate adsorbs to calcium phosphate (hydroxyapatite) crystals in bone and may directly block dissolution of this mineral component of bone. In vitro studies also suggest that inhibition of osteoclast activity contributes to inhibition of bone resorption. Pamidronate also targets farnesyl pyrophosphate (FPP) synthase. Nitrogen-containing bisphosphonates (such as pamidronate, alendronate, risedronate, ibandronate and zoledronate) appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting FPP synthase, an enzyme in the mevalonate pathway. Inhibition of this enzyme in osteoclasts prevents the biosynthesis of isoprenoid lipids (FPP and GGPP) that are essential for the post-translational farnesylation and geranylgeranylation of small GTPase signalling proteins. This activity inhibits osteoclast activity and reduces bone resorption and turnover. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass.

24,25-Dihydroxyvitamin D
24,25-Dihydroxyvitamin D (24R,25(OH)2D3) circulates in blood at concentrations about 1000 times higher than 1alpha,25(OH)2D3. 24-Hydroxylase is present in the proximal convoluted tubule cells of the kidney and in virtual all target cells of 1alpha,25(OH)2D3. Interestingly, 1alpha,25(OH)2D3 is a very strong inducer of 24-hydroxylase activity and 24R,25(OH)2D3 formation. Also parathyroid hormone (PTH) regulates 24-hydroxylase activity but in a tissue specific manner, i.e. inhibitory in the kidney while a synergistic effect together with 1alpha,25(OH)2D3 is observed in osteoblasts. Generally, 24-hydroxylation has been considered the first step in the degradation pathway of 1alpha,25(OH)2D3 and 25-(OH)D3. However, through the past decades data have accumulated that 24R,25(OH)2D3 is not merely a degradation product but has effects on its own. Classic studies have demonstrated the significance of 24R,25(OH)2D3 for normal chicken egg hatchability and calcium and phosphorus homeostasis. More recently it became apparent that 24R,25(OH)2D3 also has distinct effects on cartilage in particular the resting zone cells. 24R,25(OH)2D3 stimulates osteocalcin synthesis in human osteoblasts. 24R,25(OH)2D3 plays a role in bone metabolism but that it acts in concert with 1alpha,25(OH)2D3 to obtain an optimal effect.

Risedronate
Risedronate is only found in individuals that have used or taken this drug. It is a bisphosphonate used to strengthen bone, treat or prevent osteoporosis, and treat Pagets disease of bone.The action of risedronate on bone tissue is based partly on its affinity for hydroxyapatite, which is part of the mineral matrix of bone.

Lipid A
Lipid A is a lipid component of an endotoxin held responsible for toxicity of Gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide (LPS, also called endotoxin) molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane. While its toxic effects can be damaging, the sensing of lipid A by the human immune system may also be critical for the onset of immune responses to Gram-negative infection, and for the subsequent successful fight against the infection. Many of the immune activating abilities of LPS can be attributed to the lipid A unit. It is a very potent stimulant of the immune system, activating cells (for example, monocytes or macrophages) at picogram per milliliter quantities. Lipid A has been found in Escherichia, Pseudomonas, Salmonella and meningococcus (PMID: 11948150; PMID: 12045108).

Beryllium
Beryllium is a light-weight metallic element, which was first recognized as a lung hazard in Europe in the 1930s, shortly after its first production in modern industry. People exposed to beryllium compounds are at increased risk of developing beryllium sensitization and chronic beryllium disease (CBD). The chronic lung disease was first described among workers exposed to beryllium-containing materials used in the manufacture of fluorescent lamps. In primary production of beryllium metal, which was used in nuclear weapons components, physicians recognized severe dermatitis, reversible pneumonitis, and chronic granulomatous lung disease. Physiologically, this metal/element exists as an ion in the body. It is now recognized that the physicochemical properties of beryllium compounds may account for the differing clinical presentations in different industries. In primary production of beryllium metal, soluble salts are present and cause rashes in approximately one fourth of exposed workers and reversible acute pneumonitis in a smaller portion of the workforce. After heavy inhalation exposures, radiographic abnormalities evolve at approximately three weeks; resolution of symptoms and radiologic abnormalities away from exposure occur only after months, but symptoms recur immediately upon reexposure. The granulomatous nature of chronic beryllium disease is now known to be caused by cell-mediated sensitization to beryllium. Chronic beryllium disease (CBD) is a granulomatous lung disorder characterized by the accumulation of beryllium-specific CD4(+) T cells. Depending on genetic susceptibility and the nature of the exposure, CBD occurs in up to 20\\% of exposed workers. Genetic susceptibility has been associated with particular HLA-DP alleles, especially those possessing a negatively charged glutamic acid residue at the 69th position of the beta-chain. The mechanism for this association lies in the ability of these HLA-DP molecules to bind and present beryllium to pathogenic CD4(+) T cells. Large numbers of effector memory, beryllium-specific CD4(+) T cells are recruited to the lung of these subjects and secrete Th1-type cytokines upon beryllium recognition. The presence of circulating beryllium-specific CD4(+) T cells directly correlates with the severity of lymphocytic alveolitis. Since 1987, this biomarker of sensitization has enabled medical surveillance of beryllium-exposed workforces. Beryllium lymphocyte proliferation tests have been used to screen workers to detect sensitization, to characterize epidemiologically workplace risks for beryllium sensitization, and to evaluate the effectiveness of interventions intended to prevent sensitization. The most compelling real-world example of genetic testing for susceptibility to a workplace exposure involves those industries that process or fabricate beryllium. Under reasonable assumptions, the longitudinal positive predictive value of the HLA-DPB1-Glu69 marker of susceptibility to beryllium disease is 12\\%. Interpretive challenges further limit the utility of the test and may inadvertently suggest a false sense of safety among workers. Reduction in inhalation exposure to beryllium has not resulted in a concomitant reduction in the occurrence of beryllium sensitization or CBD, suggesting that continued prevalence may be due, in part, to unchecked skin exposure to beryllium-containing particles. (PMID: 17094767, 16697706, 16231190) [HMDB]. Beryllium is found in spinach.

In primary production of beryllium metal, soluble salts are present and cause rashes in approximately one fourth of exposed workers and reversible acute pneumonitis in a smaller portion of the workforce. After heavy inhalation exposures, radiographic abnormalities evolve at approximately three weeks; resolution of symptoms and radiologic abnormalities away from exposure occur only after months, but symptoms recur immediately upon reexposure. The granulomatous nature of chronic beryllium disease is now known to be caused by cell-mediated sensitization to beryllium. Chronic beryllium disease (CBD) is a granulomatous lung disorder characterized by the accumulation of beryllium-specific CD4(+) T cells. Depending on genetic susceptibility and the nature of the exposure, CBD occurs in up to 20\\% of exposed workers. Genetic susceptibility has been associated with particular HLA-DP alleles, especially those possessing a negatively charged glutamic acid residue at the 69th position of the beta-chain. The mechanism for this association lies in the ability of these HLA-DP molecules to bind and present beryllium to pathogenic CD4(+) T cells. Large numbers of effector memory, beryllium-specific CD4(+) T cells are recruited to the lung of these subjects and secrete Th1-type cytokines upon beryllium recognition. The presence of circulating beryllium-specific CD4(+) T cells directly correlates with the severity of lymphocytic alveolitis. Since 1987, this biomarker of sensitization has enabled medical surveillance of beryllium-exposed workforces. Beryllium lymphocyte proliferation tests have been used to screen workers to detect sensitization, to characterize epidemiologically workplace risks for beryllium sensitization, and to evaluate the effectiveness of interventions intended to prevent sensitization. The most compelling real-world example of genetic testing for susceptibility to a workplace exposure involves those industries that process or fabricate beryllium. Under reasonable assumptions, the longitudinal positive predictive value of the HLA-DPB1-Glu69 marker of susceptibility to beryllium disease is 12\\%. Interpretive challenges further limit the utility of the test and may inadvertently suggest a false sense of safety among workers. Reduction in inhalation exposure to beryllium has not resulted in a concomitant reduction in the occurrence of beryllium sensitization or CBD, suggesting that continued prevalence may be due, in part, to unchecked skin exposure to beryllium-containing particles.

Leukotriene B4
Leukotriene B4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region, and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by omega-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the omega-carboxy position and after CoA ester formation. Other specific pathways of leukotriene metabolism include the 12-hydroxydehydrogenase/15-oxo-prostaglandin-13-reductase that form a series of conjugated diene metabolites that have been observed to be excreted in human urine. Metabolism of LTC4 occurs by sequential peptide cleavage reactions involving a gamma-glutamyl transpeptidase that forms LTD4 (leukotriene D4) and a membrane-bound dipeptidase that converts LTD4 into LTE4 (leukotriene E4) before omega-oxidation. These metabolic transformations of the primary leukotrienes are critical for termination of their biological activity, and defects in expression of participating enzymes may be involved in specific genetic disease. The term leukotriene was coined to indicate the presence of three conjugated double bonds within the 20-carbon structure of arachidonic acid as well as the fact that these compounds were derived from leucocytes such as PMNNs or transformed mast cells. Interestingly, most of the cells known to express 5-LO are of myeloid origin, which includes neutrophils, eosinophils, mast cells, macrophages, basophils, and monocytes. Leukotriene biosynthesis begins with the specific oxidation of arachidonic acid by a free radical mechanism as a consequence of interaction with 5-LO. The first enzymatic step involves the abstraction of a hydrogen atom from C-7 of arachidonate followed by the addition of molecular oxygen to form 5-HpETE (5-hydroperoxyeicosatetraenoic acid). A second enzymatic step is also catalyzed by 5-LO and involves removal of a hydrogen atom from C-10, resulting in the formation of the conjugated triene epoxide LTA4. LTA4 must then be released by 5-LO and encounter either LTA4-H (LTA4 hydrolase) or LTC4-S [LTC4 (leukotriene C4) synthase]. LTA4-H can stereospecifically add water to C-12 while retaining a specific double-bond geometry, leading to LTB4 [leukotriene B4, 5(S),12(R)-dihydroxy-6,8,10,14-(Z,E,E,Z)-eicosatetraenoic acid]. If LTA4 encounters LTC4-S, then the reactive epoxide is opened at C-6 by the thiol anion of glutathione to form the product LTC4 [5(S)-hydroxy-6(R)-S-glutathyionyl-7,9,11,14- (E,E,Z,Z)-eicosatetraenoic acid], essentially a glutathionyl adduct of oxidized arachidonic acid. Both of these terminal leukotrienes are biologically active in that specific GPCRs recognize these chemical structures and receptor recognition initiates complex intracellular signalling cascades. In order for these molecules to serve as lipid mediators, however, they must be released from the biosynthetic cell into the extracellular milieu so that they can encounter the corresponding GPCRs. Surprising features of this cascade include the recognition of the assembly of critical enzymes at the perinuclear region of the cell and even localization of 5-LO within the nucleus of some cells. Under some situations, the budding phagosome has been found to assemble these proteins. Non-enzymatic proteins such as FLAP are now known as critical partners of this protein-machine assembly. An unexpected pathway of leukotriene biosynthesis involves the transfer of the chemically reactive intermediate, LTA4, from the biosynthetic cell followed by conversion into LTB4 or LTC4 by other cells that do not express ...
13,14-Dihydro-15-keto-PGE2
13,14-dihydro-15-keto-PGE2 is one of the prostaglandin E2 metabolites. (PMID 7190512) Human fetal lung in vitro has the competence to self-differentiate, as early as 12 weeks gestation and presence of high levels in fetal lung of the inactive metabolite 13,14-dihydro-15-keto-PGE2 relative to PGE2 suggests that active prostaglandin catabolism may be one of the mechanisms to retard this stage of maturation in vivo by limiting PGE2 availability. (PMID 8835315)Dinoprostone is a naturally occurring prostaglandin E2 (PGE2) and the most common and most biologically active of the mammalian prostaglandins. It has important effects in labour and also stimulates osteoblasts to release factors which stimulate bone resorption by osteoclasts (a type of bone cell that removes bone tissue by removing the bones mineralized matrix). PGE2 has been shown to increase vasodilation and cAMP production, to enhance the effects of bradykinin and histamine, to induce uterine contractions and to activate platelet aggregation. PGE2 is also responsible for maintaining the open passageway of the fetal ductus arteriosus; decreasing T-cell proliferation and lymphocyte migration and activating the secretion of IL-1alpha and IL-2. PGE2 exhibits both pro- and anti-inflammatory effects, particularly on dendritic cells (DC). Depending on the nature of maturation signals, PGE2 has different and sometimes opposite effects on DC biology. PGE2 exerts an inhibitory action, reducing the maturation of DC and their ability to present antigen. PGE2 has also been shown to stimulate DC and promote IL-12 production when given in combination with TNF-alpha. PGE2 is an environmentally bioactive substance. Its action is prolonged and sustained by other factors especially IL-10. It modulates the activities of professional DC by acting on their differentiation, maturation and their ability to secrete cytokines. PGE2 is a potent inducer of IL-10 in bone marrow-derived DC (BM-DC), and PGE2-induced IL-10 is a key regulator of the BM-DC pro-inflammatory phenotype. (PMID: 16978535)Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. 13,14-dihydro-15-keto-PGE2 is one of the prostaglandin E2 metabolites.

Neopterin
Neopterin, also known as monapterin, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative and are mainly synthesized in several parts of the body, including the pineal gland. Neopterin is a solid that is soluble in water. Neopterin is a catabolic product of guanosine triphosphate (GTP). In humans, it is involved in pterine biosynthesis and it also serves as a precursor in the biosynthesis of biopterin, which is an essential cofactor in neurotransmitter synthesis. Neopterin has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Most uremic toxins are metabolic waste products and are normally excreted in the urine or feces. Uremic toxins can cause kidney, liver and heart damage. They can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Uremic toxins such as neopterin are actively transported into the kidneys via organic ion transporters (especially OAT3). Elevated levels of neopterin result from immune system activation, including from malignant cancer, allograft rejection, viral infection, and autoimmune disorders (PMID: 19500901). Measurement of neopterin concentration allows estimation of the extent of oxidative stress elicited by the immune system. Neopterin concentrations usually correlate with the extent and activity of a given disease, and are also used to monitor the course of the disease. Elevated neopterin concentrations are among the best predictors of adverse outcome in patients with HIV infection, in cardiovascular disease, and in various types of cancer. Neopterin (D-(+)-Neopterin), a catabolic product of guanosine triphosphate (GTM), serves as a marker of cellular immune system activation.
24R,25-Dihydroxyvitamin D3
24R,25-Dihydroxyvitamin D3, also known as 24(R),25(OH)2D3, is a vitamin D metabolite; a dihydroxylated form of the seco-steroid. With the identification of a target cell, the growth plate resting zone (RC) chondrocyte, studies indicate that there are specific membrane-associated signal transduction pathways that mediate both rapid, nongenomic, and genomic responses of RC cells to 24(R),25(OH)2D3. These studies indicate that 24(R),25(OH)2D3 plays an important role in endochondral ossification by regulating less mature chondrocytes and promoting their maturation in the endochondral lineage. 24(R),25(OH)2D3 binds RC chondrocyte membranes with high specificity, increasing protein kinase C (PKC) activity. The effect is stereospecific; 24R,25(OH)2D3, but not 24S,25(OH)2D3, causes the increase, indicating a receptor-mediated response. Phospholipase D-2 (PLD2) activity is increased, resulting in increased production of diacylglycerol (DAG), which in turn activates PKC. 24(R),25(OH)2D3 does not cause translocation of PKC to the plasma membrane but activates existing PKCα. There is a rapid decrease in Ca2+ efflux, and the influx is stimulated. 24(R),25(OH)2D3 also reduces arachidonic acid release by decreasing phospholipase A2 (PLA2) activity, thereby decreasing the available substrate for prostaglandin production via the action of cyclooxygenase-1. PGE2 that is produced acts on the EP1 and EP2 receptors expressed by RC cells to downregulate PKC via protein kinase A, but the reduction in PGE2 decreases this negative feedback mechanism. Both pathways converge on MAP kinase, leading to new gene expression. One consequence of this is the production of new matrix vesicles containing PKCα and PKCγ, and an increase in PKC activity. The chondrocytes also produce 24(R),25(OH)2D3, and the secreted metabolite acts directly on the matrix vesicle membrane. Only PKCγ is directly affected by 24(R),25(OH)2D3 in the matrix vesicles, and activity of this isoform is inhibited. This effect may be involved in the control of matrix maturation and turnover. 24(R),25(OH)2D3 causes RC cells to mature along the endochondral developmental pathway, where they become responsive to 1α,25(OH)2D3 and lose responsiveness to 24(R),25(OH)2D3, a characteristic of more mature growth zone (GC) chondrocytes. 1α,25(OH)2D3 elicits its effects on GC through different signal transduction pathways than those used by 24(R),25(OH)2D3 (PMID: 11179745). 24R,25-Dihydroxyvitamin D3 (24(R),25(OH)2D3 ) is a vitamin D metabolite, a dihydroxylated form of the seco-steroid.

9,13-cis-Retinoic acid
9,13-cis-Retinoic acid belongs to the class of organic compounds known as retinoids. These are oxygenated derivatives of 3,7-dimethyl-1-(2,6,6-trimethylcyclohex-1-enyl)nona-1,3,5,7-tetraene and derivatives thereof. Retinoids (vitamin A and its analogs) are essential dietary substances that are needed by mammals for reproduction, normal embryogenesis, growth, vision, and maintaining normal cellular differentiation and the integrity of the immune system. Within cells, retinoids regulate gene transcription acting through ligand-dependent transcription factors, the retinoic acid receptors (RARs), and the retinoid X receptors (RXRs). Tretinoin, also known as all-trans-retinoic acid (ATRA), is a naturally occurring derivative of vitamin A (retinol). Retinoids such as tretinoin are important regulators of cell reproduction, proliferation, and differentiation and are used to treat acne and photodamaged skin and to manage keratinization disorders such as ichthyosis and keratosis follicularis. Tretinoin also represents the class of anticancer drugs called differentiating agents and is used in the treatment of acute promyelocytic leukemia (APL).

Arabinofuranosylcytosine
Isolated from the mushroom Xerocomus nigromaculatus of unknown palatability This compound has been identified in human blood as reported by (PMID: 31557052 ). Arabinofuranosylcytosine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Arabinofuranosylcytosine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. Arabinofuranosylcytosine (Ara-C), also known as cytarabine, is a chemotherapeutic agent that is widely used in the treatment of various types of cancer, particularly hematological malignancies such as acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). The biological functions of Ara-C are primarily related to its antineoplastic properties, which are derived from its mechanism of action within the cell. Here is a detailed description of its biological functions: 1. **Inhibition of DNA Synthesis**: Ara-C functions as a nucleoside analog, which means it resembles the natural building blocks of DNA. Once inside the cell, Ara-C is converted to its active metabolite, araCTP (arabinofuranosylcytosine triphosphate). AraCTP competes with the natural deoxycytidine triphosphate (dCTP) for incorporation into the growing DNA chain during the S phase of the cell cycle. Because Ara-C lacks a 3'-hydroxyl group, its incorporation into DNA leads to chain termination, effectively stopping DNA synthesis. 2. **Cell Cycle Specificity**: Ara-C is most effective against cells that are actively dividing. Since it targets cells in the S phase of the cell cycle, it is particularly harmful to rapidly dividing cancer cells, which often spend a significant portion of their cycle in this phase. 3. **Inhibition of DNA Repair**: Beyond its direct effect on DNA synthesis, Ara-C can also interfere with DNA repair mechanisms. This is because the incorporation of Ara-C into DNA can cause mispairing and induce DNA damage, which the cell may be unable to repair properly. 4. **Cell Death Induction**: The inhibition of DNA synthesis and the induction of DNA damage can lead to cell death through apoptosis or necrosis. Cells that cannot replicate their DNA or repair the damage caused by Ara-C activation are programmed to die, which is a desirable outcome in the context of cancer treatment. 5. **Immune System Modulation**: In some cases, Ara-C can also modulate the immune system, although this is not its primary function. It can affect the function and proliferation of immune cells, which can have implications for both its therapeutic effects and side effects. 6. **Enzymatic Conversion**: Ara-C must be activated within the cell by the enzyme deoxycytidine kinase (dCK), which phosphorylates it to Ara-CMP (monophosphate), then to Ara-CDP (diphosphate), and finally to Ara-CTP. The efficiency of this conversion can vary between different types of cancer cells and normal cells, contributing to the selectivity of Ara-C's action. 7. **Cross-Linking Potential**: Although less common, Ara-C can also form cross-links with DNA, further complicating DNA structure and function, which can contribute to its cytotoxic effects. The biological functions of Ara-C are complex and can vary depending on the dose, the specific cancer type, and the individual patient's metabolism. Its use is carefully monitored in clinical settings due to its potential for significant side effects, including myelosuppression (decreased production of blood cells), gastrointestinal toxicity, and central nervous system toxicity.

24 25-Dihydroxy VD3
24,25-Dihydroxyvitamin D (24R,25(OH)2D3) circulates in blood at concentrations about 1000 times higher than 1alpha,25(OH)2D3. 24-Hydroxylase is present in the proximal convoluted tubule cells of the kidney and in virtual all target cells of 1alpha,25(OH)2D3. Interestingly, 1alpha,25(OH)2D3 is a very strong inducer of 24-hydroxylase activity and 24R,25(OH)2D3 formationand is) also parathyroid hormone (PTH) regulates 24-hydroxylase activity but in a tissue specific manner, i.e. inhibitory in the kidney while a synergistic effect together with 1alpha,25(OH)2D3 is observed in osteoblasts. Generally, 24-hydroxylation has been considered the first step in the degradation pathway of 1alpha,25(OH)2D3 and 25-(OH)D3. However, through the past decades data have accumulated that 24R,25(OH)2D3 is not merely a degradation product but has effects on its own. Classic studies have demonstrated the significance of 24R,25(OH)2D3 for normal chicken egg hatchability and calcium and phosphorus homeostasis. More recently it became apparent that 24R,25(OH)2D3 also has distinct effects on cartilage in particular the resting zone cells. 24R,25(OH)2D3 stimulates osteocalcin synthesis in human osteoblasts. 24R,25(OH)2D3 plays a role in bone metabolism but that it acts in concert with 1alpha,25(OH)2D3 to obtain an optimal effect.
