3,4-Dihydroxybenzeneacetic acid

3,4-Dihydroxyphenylacetic Acid, Monosodium Salt

C8H8O4 (168.0423)


3,4-Dihydroxyphenylacetic acid (DOPAC) is a phenolic acid. DOPAC is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily into DOPAC via aldehyde dehydrogenase (ALDH2). The biotransformation of DOPAL is critical as previous studies have demonstrated this DA-derived aldehyde to be a reactive electrophile and toxic to dopaminergic cells. Known inhibitors of mitochondrial ALDH2, such as 4-hydroxy-2-nonenal (4HNE) inhibit ALDH2-mediated oxidation of the endogenous neurotoxin DOPAL. 4HNE is one of the resulting products of oxidative stress, thus linking oxidative stress to the uncontrolled production of an endogenous neurotoxin relevant to Parkinsons disease. In early-onset Parkinson disease, there is markedly reduced activities of both monoamine oxidase (MAO) A and B. The amount of DOPAC, which is produced during dopamine oxidation by MAO, is greatly reduced as a result of increased parkin overexpression. Administration of methamphetamine to animals causes loss of DA terminals in the brain and significant decreases in dopamine and dihydroxyphenylacetic acid (DOPAC) in the striatum. Renal dopamine produced in the residual tubular units may be enhanced during a sodium challenge, thus behaving appropriately as a compensatory natriuretic hormone; however, the renal dopaminergic system in patients afflicted with renal parenchymal disorders should address parameters other than free urinary dopamine, namely the urinary excretion of L-DOPA and metabolites. DOPAC is one of the major phenolic acids formed during human microbial fermentation of tea, citrus, and soy flavonoid supplements. DOPAC exhibits a considerable antiproliferative effect in LNCaP prostate cancer and HCT116 colon cancer cells. The antiproliferative activity of DOPAC may be due to its catechol structure. A similar association of the catechol moiety in the B-ring with antiproliferative activity was demonstrated for flavanones (PMID:16956664, 16455660, 8561959, 11369822, 10443478, 16365058). DOPAC can be found in Gram-positive bacteria (PMID:24752840). 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. 3,4-Dihydroxyphenylacetic acid is found in many foods, some of which are alaska blueberry, cauliflower, ucuhuba, and fox grape. 3,4-Dihydroxybenzeneacetic acid is the main neuronal metabolite of dopamine.

Xanthosine

9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-9H-purine-2,6-diol

C10H12N4O6 (284.0757)


Xanthosine, also known as xanthine riboside, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Xanthosine is a nucleoside derived from xanthine and ribose. Xanthosine exists in all living species, ranging from bacteria to plants to humans. In plants xanthosine is the biosynthetic precursor to 7-methylxanthosine which is produced by the action of the enzyme known as 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (the active alkaloid in chocolate), which in turn is the precursor to caffeine, the active alkaloid in coffee and tea. Within humans, xanthosine participates in a number of enzymatic reactions. In particular, xanthosine can be biosynthesized from xanthylic acid; which is catalyzed by the enzyme cytosolic purine 5-nucleotidase. In addition, xanthosine can be converted into xanthine and ribose 1-phosphate; which is mediated by the enzyme purine nucleoside phosphorylase. Xanthosine monophosphate (XMP) is an intermediate in purine metabolism, formed from IMP (inosine monophosphate).

Phentermine

(alpha,alpha)-Dimethylphenethylamine

C10H15N (149.1204)


Phentermine is only found in individuals that have used or taken this drug. It is a central nervous system stimulant and sympathomimetic with actions and uses similar to those of dextroamphetamine. It has been used most frequently in the treatment of obesity. [PubChem]Phentermine is an amphetamine that stimulates neurons to release or maintain high levels of a particular group of neurotransmitters known as catecholamines; these include dopamine and norepinephrine. High levels of these catecholamines tend to suppress hunger signals and appetite. The drug seems to inhibit reuptake of noradrenaline, dopamine, and seratonin through inhibition or reversal of the reuptake transporters. It may also inhibit MAO enzymes leaving more neurotransmitter available at the synapse.Phentermine (through catecholamine elevation) may also indirectly affect leptin levels in the brain. It is theorized that phentermine can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This peptide initiates eating, decreases energy expenditure, and increases fat storage.

Geranial

trans-3,7-Dimethyl-2,6-octadien-1-al

C10H16O (152.1201)


Geranial, also known as 3,7-dimethyl-2,6-octadienal, citral or lemonal, belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Thus, citral is considered to be an isoprenoid lipid. Two different isomers of 3,7-dimethyl-2,6-octadienal exist. The E-isomer or trans-isomer is known as geranial or citral A. The Z-isomer or cis-isomer is known as neral or citral B. 3,7-dimethyl-2,6-octadienal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Citral is present in the oils of several plants, including lemon myrtle (90-98\\\\%), Litsea citrata (90\\\\%), Litsea cubeba, lemongrass (65-80\\\\%), lemon tea-tree (70-80\\\\%), Ocimum gratissimum, Lindera citriodora, Calypranthes parriculata, petitgrain, lemon verbena, lemon ironbark, lemon balm, lime, lemon and orange. Citral has also been reported to be found in Cannabis sativa (PMID:6991645 , 26657499 ). Citral has a strong lemon (citrus) odor. Nerals lemon odor is less intense, but sweeter. Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It has strong antimicrobial qualities (PMID:28974979 ) and pheromonal effects in nematodes and insects (PMID:26973536 ). Citral is used in the synthesis of vitamin A, lycopene, ionone, and methylionone (a compound used to mask the smell of smoke). Occurs in lemon grass oil (Cymbopogon citratus), lemon, orange and many other essential oils; flavouring ingredient. Geranial is found in many foods, some of which are watermelon, nutmeg, cloud ear fungus, and yellow wax bean. Citral is a monoterpene found in Cymbopogon citratus essential oil, with antihyperalgesic, anti-nociceptive and anti-inflammatory effects[1].

C25H36O8 (464.241)


Testosterone glucuronide is a natural human metabolite of testosterone. Testosterone is a steroid hormone from the androgen group. testosterone is primarily secreted in the testes of males and the ovaries of females although small amounts are secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. In both males and females, it plays key roles in health and well-being. There is a sex difference in the median values of testosterone glucuronide in the amniotic fluid specimens 15-19 wk gestation between female (median 160 pM, range 64-465 pM) and male (median 817 pM, range 68-3707 pM). This difference, when used in conjunction with amniotic fluid unconjugated testosterone values, increase the predictive accuracy of fetal sexing from 95.4 to 98.9\\\%. In human newborns and young infants, urinary testosterone sulfate is higher than glucuronide. The high sulfokinase activity in fetal and neonatal testes is more likely responsible for this phenomenon than an impaired glucuronizing capacity of the liver. Urinary excretion of testosterone glucuronide increases significantly during puberty. The level of testosterone glucuronide exceeds the level of unconjugated testosterone in human seminal plasma. Urinary testosterone glucuronide excretion is increased in women with virilizing adrenocortical tumors. Concentration of testosterone glucuronide in urine from women with breast tumor in urine samples is not different from patients with benign or malignant breast disease, either before or after the menopause.

C23H23N3O5 (421.1638)


Topotecan is only found in individuals that have used or taken this drug. It is an antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. [PubChem]Topotecan has the same mechanism of action as irinotecan and is believed to exert its cytotoxic effects during the S-phase of DNA synthesis. Topoisomerase I relieves torsional strain in DNA by inducing reversible single strand breaks. Topotecan binds to the topoisomerase I-DNA complex and prevents religation of these single strand breaks. This ternary complex interferes with the moving replication fork, which leads to the induction of replication arrest and lethal double-stranded breaks in DNA. As mammalian cells cannot efficiently repair these double strand breaks, the formation of this ternary complex eventually leads to apoptosis (programmed cell death).Topotecan mimics a DNA base pair and binds at the site of DNA cleavage by intercalating between the upstream (−1) and downstream (+1) base pairs. Intercalation displaces the downstream DNA, thus preventing religation of the cleaved strand. By specifically binding to the enzyme–substrate complex, Topotecan acts as an uncompetitive inhibitor. Topotecan is a pyranoindolizinoquinoline used as an antineoplastic agent. It is a derivative of camptothecin and works by binding to the topoisomerase I-DNA complex and preventing religation of these 328 single strand breaks. It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor and an antineoplastic agent. An antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. Topotecan is a Topoisomerase Inhibitor. The mechanism of action of topotecan is as a Topoisomerase Inhibitor. Topotecan is a semisynthetic derivative of camptothecin, a cytotoxic, quinoline-based alkaloid extracted from the Asian tree Camptotheca acuminata. Topotecan inhibits topoisomerase I activity by stabilizing the topoisomerase I-DNA covalent complexes during S phase of cell cycle, thereby inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when encountered by the DNA replication machinery.

Benzaldehyde

benzaldehyde

C7H6O (106.0419)


Benzaldehyde is occasionally found as a volatile component of urine. Benzaldehyde is an aromatic aldehyde used in cosmetics as a denaturant, a flavoring agent, and as a fragrance. Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5\\\% in perfumes. Benzaldehyde is a generally regarded as safe (GRAS) food additive in the United States and is accepted as a flavoring substance in the European Union. Because Benzaldehyde rapidly metabolizes to Benzoic Acid in the skin, the available dermal irritation and sensitization data demonstrating no adverse reactions to Benzoic Acid were considered supportive of the safety of Benzaldehyde. Benzaldehyde is absorbed through skin and by the lungs, distributes to all well-perfused organs, but does not accumulate in any specific tissue type. After being metabolized to benzoic acid, conjugates are formed with glycine or glucuronic acid, and excreted in the urine. Several studies have suggested that Benzaldehyde can have carcinostatic or antitumor properties. Overall, at the concentrations used in cosmetics, Benzaldehyde was not considered a carcinogenic risk to humans. Although there are limited irritation and sensitization data available for Benzaldehyde, the available dermal irritation and sensitization data and ultraviolet (UV) absorption and phototoxicity data demonstrating no adverse reactions to Benzoic Acid support the safety of Benzaldehyde as currently used in cosmetic products. (PMID:16835129, Int J Toxicol. 2006;25 Suppl 1:11-27.). Benzaldehyde, a volatile organic compound, is naturally present in a variety of plants, particularly in certain fruits, nuts, and flowers. It plays a significant role in the aromatic profiles of these plants. For instance, benzaldehyde is a primary component of bitter almond oil, which was one of its earliest known natural sources. Besides bitter almonds, it is also found in fruits like cherries, peaches, and plums, as well as in flowers such as jasmine. In the food industry, benzaldehyde is occasionally used as a food additive to impart specific flavors. This prevalence in plants highlights that benzaldehyde is not only an industrial chemical but also a naturally occurring compound in the plant kingdom. Its presence in these natural sources underscores its significance in both nature and industry. Found in plants, especies in almond kernelsand is) also present in strawberry jam, leek, crispbread, cheese, black tea and several essential oils. Parent and derivs. (e.g. glyceryl acetal) are used as flavourings

   

Retinol(Vitamin A)

3,7-Dimethyl-9-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4,6,8-nonatetraen-1-ol, (all-e)-isomer

C20H30O (286.2297)


Vitamin A (retinol) is a yellow fat-soluble, antioxidant vitamin important in vision and bone growth. It belongs to the family of chemical compounds known as retinoids. Retinol is ingested in a precursor form; animal sources (milk and eggs) contain retinyl esters, whereas plants (carrots, spinach) contain pro-vitamin A carotenoids. Hydrolysis of retinyl esters results in retinol while pro-vitamin A carotenoids can be cleaved to produce retinal. Retinal, also known as retinaldehyde, can be reversibly reduced to produce retinol or it can be irreversibly oxidized to produce retinoic acid. Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of carotenoids found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products. Retinyl esters from animal-sourced foods (or synthesized for dietary supplements for humans and domesticated animals) are acted upon by retinyl ester hydrolases in the lumen of the small intestine to release free retinol. Retinol enters intestinal absorptive cells by passive diffusion. Absorption efficiency is in the range of 70 to 90\%. Humans are at risk for acute or chronic vitamin A toxicity because there are no mechanisms to suppress absorption or excrete the excess in urine.[5] Within the cell, retinol is there bound to retinol binding protein 2 (RBP2). It is then enzymatically re-esterified by the action of lecithin retinol acyltransferase and incorporated into chylomicrons that are secreted into the lymphatic system. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1). The protein is upregulated in times of vitamin A deficiency. If vitamin A status is in the normal range, SCARB1 is downregulated, reducing absorption.[6] Also downregulated is the enzyme beta-carotene 15,15'-dioxygenase (formerly known as beta-carotene 15,15'-monooxygenase) coded for by the BCMO1 gene, responsible for symmetrically cleaving β-carotene into retinal.[8] Absorbed β-carotene is either incorporated as such into chylomicrons or first converted to retinal and then retinol, bound to RBP2. After a meal, roughly two-thirds of the chylomicrons are taken up by the liver with the remainder delivered to peripheral tissues. Peripheral tissues also can convert chylomicron β-carotene to retinol.[6][15] The capacity to store retinol in the liver means that well-nourished humans can go months on a vitamin A deficient diet without manifesting signs and symptoms of deficiency. Two liver cell types are responsible for storage and release: hepatocytes and hepatic stellate cells (HSCs). Hepatocytes take up the lipid-rich chylomicrons, bind retinol to retinol-binding protein 4 (RBP4), and transfer the retinol-RBP4 to HSCs for storage in lipid droplets as retinyl esters. Mobilization reverses the process: retinyl ester hydrolase releases free retinol which is transferred to hepatocytes, bound to RBP4, and put into blood circulation. Other than either after a meal or when consumption of large amounts exceeds liver storage capacity, more than 95\% of retinol in circulation is bound to RBP4.[15] Vitamin A is a fat-soluble vitamin, hence an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinal (also known as retinaldehyde), retinoic acid, and several provitamin (precursor) carotenoids, most notably beta-carotene.[3][4][5][6] Vitamin A has multiple functions: essential in embryo development for growth, maintaining the immune system, and healthy vision, where it combines with the protein opsin to form rhodopsin – the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision.[7] Vitamin A occurs as two principal forms in foods: A) retinol, found in animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids alpha-carotene, β-carotene, gamma-carotene, and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that function as provitamin A in herbivore and omnivore animals which possess the enzymes that cleave and convert provitamin carotenoids to retinal and then to retinol.[8] Some carnivore species lack this enzyme. The other carotenoids have no vitamin activity.[6] Dietary retinol is absorbed from the digestive tract via passive diffusion. Unlike retinol, β-carotene is taken up by enterocytes by the membrane transporter protein scavenger receptor B1 (SCARB1), which is upregulated in times of vitamin A deficiency.[6] Storage of retinol is in lipid droplets in the liver. A high capacity for long-term storage of retinol means that well-nourished humans can go months on a vitamin A- and β-carotene-deficient diet, while maintaining blood levels in the normal range.[4] Only when the liver stores are nearly depleted will signs and symptoms of deficiency show.[4] Retinol is reversibly converted to retinal, then irreversibly to retinoic acid, which activates hundreds of genes.[9] Vitamin A deficiency is common in developing countries, especially in Sub-Saharan Africa and Southeast Asia. Deficiency can occur at any age but is most common in pre-school age children and pregnant women, the latter due to a need to transfer retinol to the fetus. Vitamin A deficiency is estimated to affect approximately one-third of children under the age of five around the world, resulting in hundreds of thousands of cases of blindness and deaths from childhood diseases because of immune system failure.[10] Reversible night blindness is an early indicator of low vitamin A status. Plasma retinol is used as a biomarker to confirm vitamin A deficiency. Breast milk retinol can indicate a deficiency in nursing mothers. Neither of these measures indicates the status of liver reserves.[6] The European Union and various countries have set recommendations for dietary intake, and upper limits for safe intake. Vitamin A toxicity also referred to as hypervitaminosis A, occurs when there is too much vitamin A accumulating in the body. Symptoms may include nervous system effects, liver abnormalities, fatigue, muscle weakness, bone and skin changes, and others. The adverse effects of both acute and chronic toxicity are reversed after consumption of high dose supplements is stopped.[6]

Acetaldehyde

Acetic aldehyde

C2H4O (44.0262)


Acetaldehyde, also known as ethanal, belongs to the class of organic compounds known as short-chain aldehydes. These are an aldehyde with a chain length containing between 2 and 5 carbon atoms. Acetaldehyde exists in all living species, ranging from bacteria to humans. Within humans, acetaldehyde participates in a number of enzymatic reactions. In particular, acetaldehyde can be biosynthesized from ethanol which is mediated by the enzyme alcohol dehydrogenase 1B. Acetaldehyde can also be converted to acetic acid by the enzyme aldehyde dehydrogenase (mitochondrial) and aldehyde dehydrogenase X (mitochondrial). The main method of production is the oxidation of ethylene by the Wacker process, which involves oxidation of ethylene using a homogeneous palladium/copper system: 2 CH2CH2 + O2 → 2 CH3CHO. In the 1970s, the world capacity of the Wacker-Hoechst direct oxidation process exceeded 2 million tonnes annually. In humans, acetaldehyde is involved in disulfiram action pathway. Acetaldehyde is an aldehydic, ethereal, and fruity tasting compound. Outside of the human body, acetaldehyde is found, on average, in the highest concentration in a few different foods, such as sweet oranges, pineapples, and mandarin orange (clementine, tangerine) and in a lower concentration in . acetaldehyde has also been detected, but not quantified in several different foods, such as malabar plums, malus (crab apple), rose hips, natal plums, and medlars. This could make acetaldehyde a potential biomarker for the consumption of these foods. In condensation reactions, acetaldehyde is prochiral. Acetaldehyde is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Acetaldehyde has been found to be associated with several diseases such as alcoholism, ulcerative colitis, nonalcoholic fatty liver disease, and crohns disease; also acetaldehyde has been linked to the inborn metabolic disorders including aldehyde dehydrogenase deficiency (III) sulfate is used to reoxidize the mercury back to the mercury. Acetaldehyde was first observed by the Swedish pharmacist/chemist Carl Wilhelm Scheele (1774); it was then investigated by the French chemists Antoine François, comte de Fourcroy and Louis Nicolas Vauquelin (1800), and the German chemists Johann Wolfgang Döbereiner (1821, 1822, 1832) and Justus von Liebig (1835). At room temperature, acetaldehyde (CH3CHO) is more stable than vinyl alcohol (CH2CHOH) by 42.7 kJ/mol: Overall the keto-enol tautomerization occurs slowly but is catalyzed by acids. The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke. Acetaldehyde is also created by thermal degradation or ultraviolet photo-degradation of some thermoplastic polymers during or after manufacture. The water industry generally recognizes 20–40 ppb as the taste/odor threshold for acetaldehyde. The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity.

Acrolein

trans-Acrolein formylethylene

C3H4O (56.0262)


Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colourless liquid with a piercing, disagreeable, acrid smell. The smell of burnt fat (i.e. when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine. Acrolein is used as an etherification agent in the preparation of modified food starches. Acrolein is an herbicide and algicide used in water treatment. It is produced by microorganisms, e.g. Clostridium perfringens. Acrolein is a relatively electrophilic compound and a reactive one, hence its high toxicity. It is a good Michael acceptor, hence its useful reaction with thiols. It forms acetals readily, a prominent one being the spirocycle derived from pentaerythritol, diallylidene pentaerythritol. Acrolein participates in many Diels-Alder reactions, even with itself. Via Diels-Alder reactions, it is a precursor to some commercial fragrances, including lyral, norbornene-2-carboxaldehyde, and myrac aldehyde. Acrolein is toxic and is a strong irritant for the skin, eyes, and nasal passages. The main metabolic pathway for acrolein is the alkylation of glutathione. The WHO suggests a tolerable oral acrolein intake of 7.5 µg/day per kilogram of body weight. Although acrolein occurs in French fries, the levels are only a few micrograms per kilogram. Acrolein has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Present in fruit aromas, black tea, carrot, cooked potato, cheeses, white wine, hydrolyzed soy protein, turkey, pork, beef fat and other foods. It is used as an etherification agent in the preparation of modified food starches. Herbicide and algicide used in water treatment. Production by microorganisms, e.g. Clostridium perfringens. 2-Propenal is found in many foods, some of which are napa cabbage, sacred lotus, devilfish, and garlic.

Hexanal

N-Caproic aldehyde

C6H12O (100.0888)


Hexanal is an alkyl aldehyde found in human biofluids. Human milk samples collected from women contains hexanal. Among mediators of oxidative stress, highly reactive secondary aldehydic lipid peroxidation products can initiate the processes of spontaneous mutagenesis and carcinogenesis and can also act as a growth-regulating factors and signaling molecules. In specimens obtained from adult patients with brain astrocytomas, lower levels of n-hexanal are associated with poorer patient prognosis. Hexanal has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Hexanal is a volatile compound that has been associated with the development of undesirable flavours. The content of hexanal, which is a major breakdown product of linoleic acid (LA, n - 6 PUFA) oxidation, has been used to follow the course of lipid oxidation and off-flavour development in foods, and have been proposed as one potential marker of milk quality. A "cardboard-like" off-flavour is frequently associated with dehydrated milk products. This effect is highly correlated with the headspace concentration of hexanal. (Food Chemistry. Volume 107, Issue 1, 1 March 2008, Pages 558-569, PMID:17934948, 17487452). Constituent of many foodstuffs. A production of aerobic enzymatic transformations of plant constits.

3,4-Dihydroxyphenylacetaldehyde

Dopal (3,4-Dihydroxyphenyl)acetaldehyde)

C8H8O3 (152.0473)


3,4-Dihydroxyphenylacetaldehyde (DOPAL) is a metabolite of the monoamine oxidase-catalyzed oxidative deamination of dopamine. Aldehydes are highly reactive molecules formed during the biotransformation of numerous endogenous and exogenous compounds, including biogenic amines. DOPAL generates a free radical and activates mitochondrial permeability transition, a mechanism implicated in neuron death. There is an increasing body of evidence suggesting that these compounds are neurotoxic, and it has been recently hypothesized that neurodegenerative disorders may be associated with increased levels of this biogenic aldehyde. It is possible to speculate that reduced detoxification of 3,4- dihydroxymandelaldehyde from impaired or deficient aldehyde dehydrogenase function may be a contributing factor in the suggested neurotoxicity of these compounds. Aldehyde dehydrogenases are a group of NAD(P)+ -dependent enzymes that catalyze the oxidation of aldehydes, such as those derived from catecholamines, to their corresponding carboxylic acids. To date, 19 aldehyde dehydrogenase genes have been identified in the human genome. Mutations in these genes and subsequent inborn errors in aldehyde metabolism are the molecular basis of several diseases. Several pharmaceutical agents and environmental toxins (i.e.: 4-hydroxy-2-nonenal) are also known to disrupt or inhibit aldehyde dehydrogenase function. (PMID: 17379813, 14697885, 11164826, 16956664 [HMDB]. 3,4-Dihydroxyphenylacetaldehyde is found in many foods, some of which are asian pear, pak choy, papaya, and abiyuch. 3,4-Dihydroxyphenylacetaldehyde (DOPAL) is a metabolite of the monoamine oxidase-catalyzed oxidative deamination of dopamine.

Chloroacetaldehyde

Chloroacetaldehyde hydrate

C2H3ClO (77.9872)


Being bifunctional, chloroacetaldehyde is a versatile precursor to many heterocyclic compounds. It condenses with thiourea derivatives to give aminothiazoles. This reaction was once important as a precursor to sulfathiazole, one of the first sulfa drugs. Chloroacetaldehyde is the organic compound with the formula ClCH2CHO. Like some related compounds, it is highly electrophilic reagent and a potentially dangerous alkylating agent. The compound is not normally encountered in the anhydrous form, but rather as the hydrate (acetal), ClCH2CH(OH)2. Chloroacetaldehyde is a useful intermediate in the synthesis, e.g. of 2-aminothiazole or many pharmaceutical compounds. Another use is to facilitate bark removal from tree trunks.

   

Isosorbide Dinitrate

(3S,3aS,6R,6aS)-6-(nitrooxy)-hexahydrofuro[3,2-b]furan-3-yl nitrate

C6H8N2O8 (236.0281)


Isosorbide Dinitrate is only found in individuals that have used or taken this drug. It is a vasodilator used in the treatment of angina pectoris. Its actions are similar to nitroglycerin but with a slower onset of action. [PubChem]Similar to other nitrites and organic nitrates, isosorbide dinitrate is converted to nitric oxide (NO), an active intermediate compound which activates the enzyme guanylate cyclase (atrial natriuretic peptide receptor A). This stimulates the synthesis of cyclic guanosine 3,5-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation.

4-Hydroxycyclophosphamide

Tetrahydro-2-(bis(2-chloroethyl)amino)-2H-1,3,2-oxazaphosphorin-4-ol 2-oxide

C7H15Cl2N2O3P (276.0197)


4-Hydroxycyclophosphamide is a primary activation metabolite of cyclophosphamide and of mafosfamide (an experimental drug) after they partially metabolized by cytochrome P450 (PMID: 12021633). Cyclophosphamide is a chemotherapeutic used to suppress the immune system and to treat several cancers including lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer and small cell lung cancer. After cyclphosphamide is converted to 4-hydroxycyclophosphamide it is then partially tautomerized into aldophosphamide, which easily enters live cells whereupon it is partially detoxified into inactive carboxycyclophosphamide by the enzyme ALDH. 4-Hydroxycyclophosphamide is also an intermediate metabolite in the formation of phosphoramide mustard, the active metabolite, and acrolein, the metabolite responsible for much of the toxicity associated with cyclophosphamides (PMID: 7059981). 4-Hydroxycyclophosphamide is not cytotoxic at physiologic pH, readily diffuses into cells and spontaneously decomposes into the active phosphoramide mustard. In human liver microsomes, 4-Hydroxycyclophosphamide formation correlates with known phenotypic markers of CYP2B6 activity, specifically formation of (S)-2-ethyl-1,5-dimethyl-3,3-diphenyl pyrrolidine and hydroxybupropion. In addition, it is reported that the CYP2B6 genotype is not consistently related to 4-Hydroxycyclophosphamide formation in vitro or in vivo (PMID: 21976622). 4-Hydroxycyclophosphamide is only found in individuals who have consumed the drug cyclophosphamide.

In contrast to previous adult studies on urinary metabolites, plasma carboxyphosphamide concentrations did not support the existence of polymorphic metabolism. Plasma concentrations of dechlorethylcyclophosphamide and carboxyphosphamide were correlated in individual patients, suggesting that the activity of both aldehyde dehydrogenase and cytochrome P450 enzyme(s) determine carboxyphosphamide production in vivo. (PMID: 7850793) Detoxification of cyclophosphamide is effected, in part, by hepatic class 1 aldehyde dehydrogenase (ALDH-1)-catalyzed oxidation of aldophosphamide, a pivotal aldehyde intermediate, to the nontoxic metabolite, carboxyphosphamide. (PMID: 9394035) A key finding was the detection of a metabolite, most likely carboxyphosphamide, that is formed only by cytosols from cells expressing either class 3 or class 1 ALDH.

Phosphoramide mustard is a metabolite of cyclophosphamide. Cyclophosphamide (trade names Endoxan, Cytoxan, Neosar, Procytox, Revimmune), also known as cytophosphane, is a nitrogen mustard alkylating agent, from the oxazophorines group. An alkylating agent adds an alkyl group (CnH2n+1) to DNA. It attaches the alkyl group to the guanine base of DNA, at the number 7 nitrogen atom of the imidazole ring. It is used to treat various types of cancer and some autoimmune disorders.

Isosorbide Mononitrate

(3R,3aS,6S,6aR)-6-hydroxy-hexahydrofuro[3,2-b]furan-3-yl nitrate

C6H9NO6 (191.043)


Isosorbide mononitrate (ISMN), sold under the names Imdur and Monoket, among others, is an organic nitrate used principally in the prophylactic treatment of angina pectoris (ischemic chest pain). ISMN is an active metabolite of isosorbide dinitrate and exerts qualitatively similar effects. Like other organic nitrates, ISMN acts as a prodrug for its active metabolite, nitric oxide, which mediates the therapeutic action of ISMN. Nitric oxide works on both arteries and veins, but predominantly veins. Nitric oxide functions by relaxing veins and reducing the central venous pressure, thereby causing venous pooling and a decrease in the venous return to the heart, thus decreasing cardiac preload (PMID: 31643263). The net effect when administering ISMN is therefore a reduced workload for the heart and an improvement in the oxygen supply/demand balance of the myocardium. ISMN is not subject to first pass metabolism in the human liver. Detectable metabolites include isosorbide, sorbitol, and 2-glucuronide of mononitrate, which are pharmacologically inactive (PMID: 1449102). Research on ISMN as a cervical ripener to reduce time at hospital to birth is supportive (PMID: 23983763). Isosorbide mononitrate is only found in individuals who have consumed or used this drug.

C20H28O2 (300.2089)


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).

C8H8O4 (168.0423)


3,4-Dihydroxyphenylacetic acid (DOPAC) is a phenolic acid. DOPAC is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily into DOPAC via aldehyde dehydrogenase (ALDH2). The biotransformation of DOPAL is critical as previous studies have demonstrated this DA-derived aldehyde to be a reactive electrophile and toxic to dopaminergic cells. Known inhibitors of mitochondrial ALDH2, such as 4-hydroxy-2-nonenal (4HNE) inhibit ALDH2-mediated oxidation of the endogenous neurotoxin DOPAL. 4HNE is one of the resulting products of oxidative stress, thus linking oxidative stress to the uncontrolled production of an endogenous neurotoxin relevant to Parkinsons disease. In early-onset Parkinson disease, there is markedly reduced activities of both monoamine oxidase (MAO) A and B. The amount of DOPAC, which is produced during dopamine oxidation by MAO, is greatly reduced as a result of increased parkin overexpression. Administration of methamphetamine to animals causes loss of DA terminals in the brain and significant decreases in dopamine and dihydroxyphenylacetic acid (DOPAC) in the striatum. Renal dopamine produced in the residual tubular units may be enhanced during a sodium challenge, thus behaving appropriately as a compensatory natriuretic hormone; however, the renal dopaminergic system in patients afflicted with renal parenchymal disorders should address parameters other than free urinary dopamine, namely the urinary excretion of L-DOPA and metabolites. DOPAC is one of the major phenolic acids formed during human microbial fermentation of tea, citrus, and soy flavonoid supplements. DOPAC exhibits a considerable antiproliferative effect in LNCaP prostate cancer and HCT116 colon cancer cells. The antiproliferative activity of DOPAC may be due to its catechol structure. A similar association of the catechol moiety in the B-ring with antiproliferative activity was demonstrated for flavanones (PMID:16956664, 16455660, 8561959, 11369822, 10443478, 16365058). DOPAC can be found in Gram-positive bacteria (PMID:24752840). (3,4-dihydroxyphenyl)acetic acid is a dihydroxyphenylacetic acid having the two hydroxy substituents located at the 3- and 4-positions. It is a metabolite of dopamine. It has a role as a human metabolite. It is a dihydroxyphenylacetic acid and a member of catechols. It is functionally related to a phenylacetic acid. It is a conjugate acid of a (3,4-dihydroxyphenyl)acetate. 3,4-Dihydroxyphenylacetic acid is a natural product found in Liatris elegans, Tragopogon orientalis, and other organisms with data available. A deaminated metabolite of LEVODOPA. 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. 3,4-Dihydroxyphenylacetic acid is found in many foods, some of which are alaska blueberry, cauliflower, ucuhuba, and fox grape. 3,4-Dihydroxybenzeneacetic acid is the main neuronal metabolite of dopamine.
