3-hydroxy-3-methylglutarate

beta-Hydroxy-beta-methylglutaric acid

C6H10O5 (162.0528)


3-Hydroxymethylglutaric acid is an "off-product" intermediate in the leucine degradation process. It is produced by defective or inefficient versions of 3-hydroxy-3-methylglutaryl-CoA lyase, an enzyme that normally catalyzes the conversion of 3-hydroxy-3-methylglutaryl-CoA to acetyl-CoA and acetoacetate. If this enzyme is defective, 3-hydroxy-3-methylglutaryl-CoA will accumulate in the mitochondria. Increased concentrations of 3-hydroxy-3-methylglutaryl-CoA can lead to a disruption of the esterified CoA:free CoA ratio and ultimately to mitochondrial toxicity. Detoxification of these CoA end products occurs via the transfer of the 3-hydroxymethylglutaryl moiety to carnitine, forming 3-hydroxymethylglutaric-carnitine, which is then transferred across the inner mitochondrial membrane where 3-hydroxymethylglutaric acid is released as the free acid. 3-Hydroxymethylglutaric acid has been found to accumulate in the urine of patients affected by 3-Hydroxy-3-methylglutaric aciduria, a rare inborn error of metabolism (OMIM: 246450). 3-Hydroxy-3-methylglutaric aciduria is caused by significantly reduced enzyme activity of the intramitochondrial 3-hydroxy-3-methylglutaryl-CoA lyase (EC 4.1.3.4), the enzyme that catalyzes the final step of leucine degradation. This enzyme also plays a key role in ketone body formation. The profile of urinary organic acids for individuals with 3-hydroxy-3-methylglutaric aciduria is different from that of the other identified defects of leucine degradation, such as maple syrup urine disease (OMIM: 248600), isovaleric acidemia (OMIM: 243500), and methylcrotonylglycinemia (OMIM: 210200). The urinary organic acid profile of 3-hydroxy-3-methylglutaric aciduria includes elevated concentrations of 3-hydroxy-3-isovaleric, 3-hydroxy-3-methylglutaric, 3-methylglutaconic, and 3-methylglutaric acids (PMID: 10916782, 9658458, 3063529). Clinical manifestations of 3-hydroxy-3-methylglutaric aciduria include hepatomegaly, lethargy, coma, and apnea. Biochemically, there is a characteristic absence of ketosis with hypoglycemia, acidosis, hypertransaminasemia, and variable hyperammonemia. Therefore, when present in sufficiently high concentrations, 3-hydroxymethylglutaric 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. As noted above, chronically high levels of 3-hydroxymethylglutaric acid are associated with the inborn error of metabolism 3-hydroxy-3-methylglutaryl-CoA lyase deficiency. 3-Hydroxymethylglutaric 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-hydroxymethylglutaric acid, also known as meglutol or dicrotalic acid, is a member of the class of compounds known as hydroxy fatty acids. Hydroxy fatty acids are fatty acids in which the chain bears a hydroxyl group. 3-hydroxymethylglutaric acid is soluble (in water) and a weakly acidic compound (based on its pKa). 3-hydroxymethylglutaric acid can be synthesized from glutaric acid. 3-hydroxymethylglutaric acid is also a parent compound for other transformation products, including but not limited to, viscumneoside VII, viscumneoside IV, and yanuthone D. 3-hydroxymethylglutaric acid can be found in flaxseed, which makes 3-hydroxymethylglutaric acid a potential biomarker for the consumption of this food product. 3-hydroxymethylglutaric acid can be found primarily in saliva and urine. 3-hydroxymethylglutaric acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Chronically high levels of 3-hydroxymethylglutaric acid are associated with the inborn error of metabolism: 3-Hydroxy-3-Methylglutaryl-CoA Lyase Deficiency (T3DB). Meglutol is an antilipidemic agent that lowers cholesterol, triglycerides, and serum beta-lipoproteins and phospholipids, and inhibits hydroxymethylglutaryl-CoA reductase activity, which is the rate-limiting enzyme in cholesterol biosynthesis.

Temazepam

7-chloro-3-hydroxy-1-methyl-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one

C16H13ClN2O2 (300.0666)


Temazepam is only found in individuals that have used or taken this drug. It is a benzodiazepine that acts as a gamma-aminobutyric acid modulator and anti-anxiety agent. [PubChem]Benzodiazepines bind nonspecifically to benzodiazepine receptors, which affects muscle relaxation, anticonvulsant activity, motor coordination, and memory. As benzodiazepine receptors are thought to be coupled to gamma-aminobutyric acid-A (GABAA) receptors, this enhances the effects of GABA by increasing GABA affinity for the GABA receptor. Binding of the inhibitory neurotransmitter GABA to the site opens the chloride channel, resulting in a hyperpolarized cell membrane that prevents further excitation of the cell.

Josamycin is only found in individuals that have used or taken this drug. It is a macrolide antibiotic from Streptomyces narbonensis. The drug has antimicrobial activity against a wide spectrum of pathogens. [PubChem]The mechanism of action of macrolides such as Josamycin is via inhibition of bacterial protein biosynthesis by binding reversibly to the subunit 50S of the bacterial ribosome, thereby inhibiting translocation of peptidyl tRNA. This action is mainly bacteriostatic, but can also be bactericidal in high concentrations. Macrolides tend to accumulate within leukocytes, and are therefore actually transported into the site of infection.

Proline betaine is an osmoprotective compound found in urine. It is thought to serve an osmoprotective role for the kidney. Proline betaine is a glycine betaine analogue found in many citrus foods. Elevated levels of proline betaine in human urine are found after the consumption of citrus fruits and juices (PMID: 18060588). Proline betaine is a biomarker for the consumption of citrus fruits. Alkaloid from Citrus spp Medicago sativa and Stachys subspecies(alfalfa). L-Stachydrine or also called proline betaine is a biomarker for the consumption of citrus fruits. L-Stachydrine is found in many foods, some of which are capers, pulses, lemon, and alfalfa. Proline betaine, also known as stachydrine, belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Proline betaine exists in all living organisms, ranging from bacteria to humans. Proline betaine is found, on average, in the highest concentration within capers (Capparis spinosa). Proline betaine has also been detected, but not quantified in, several different foods, such as soy beans (Glycine max), crosnes (Stachys affinis), domestic pigs (Sus scrofa domestica), limes (Citrus aurantiifolia), and triticales (X Triticosecale rimpaui). This could make proline betaine a potential biomarker for the consumption of these foods. Proline betaine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Proline betaine. Stachydrine is a major constituent of Chinese herb leonurus heterophyllus sweet used to promote blood circulation and dispel blood stasis. Stachydrine can inhibit the NF-κB signal pathway.

Leukotriene E4

(5S-(5R*,6S*(s*),7E,9E,11Z,14Z))-6-((2-amino-2-carboxyethyl)thio)-5-hydroxy-7,9,11,14-eicosatetraenoic acid

C23H37NO5S (439.2392)


Leukotriene E4 (LTE4) is a cysteinyl leukotriene. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis. Nasal blockage induced by CysLTs is mainly due to dilatation of nasal blood vessels, which can be induced by the nitric oxide produced through CysLT1 receptor activation. LTE4 activates contractile and inflammatory processes via specific interaction with putative seven transmembrane-spanning receptors that couple to G proteins and subsequent intracellular signaling pathways. LTE4 is metabolized from leukotriene C4 in a reaction catalyzed by gamma-glutamyl transpeptidase and a particulate dipeptidase from kidney (PMID: 12607939, 12432945, 6311078). Leukotrienes 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 signaling pathways. Leukotriene E4 (LTE4) is a cysteinyl leukotriene.

Nedocromil

9-Ethyl-6,9-dihydro-4,6-dioxo-10-propyl-4H-pyrano(3,2-g)quinoline-2,8-dicarboxylic acid

C19H17NO7 (371.1005)


Nedocromil is only found in individuals that have used or taken this drug. It is a pyranoquinolone derivative that inhibits activation of inflammatory cells which are associated with asthma, including eosinophils, neutrophils, macrophages, mast cells, monocytes, and platelets. [PubChem]Nedocromil has been shown to inhibit the in vitro activation of, and mediator release from, a variety of inflammatory cell types associated with asthma, including eosinophils, neutrophils, macrophages, mast cells, monocytes, and platelets. Nedocromil inhibits activation and release of inflammatory mediators such as histamine, prostaglandin D2 and leukotrienes c4 from different types of cells in the lumen and mucosa of the bronchial tree. These mediators are derived from arachidonic acid metabolism through the lipoxygenase and cyclo-oxygenase pathways. The mechanism of action of nedocromil may be due partly to inhibition of axon reflexes and release of sensory neuropeptides, such as substance P, neurokinin A, and calcitonin-geneñrelated peptides. The result is inhibition of bradykinin-induced bronchoconstriction. Nedocromil does not posess any bronchodilator, antihistamine, or corticosteroid activity.

Dibromochloromethane belongs to the family of Organochlorides. These are organic compounds containing a chlorine atom

   

Bromoform

Methyl tribromide

CHBr3 (249.7628)


Bromoform, also known as Tribromomethane or Methyl tribromide, is classified as a member of the Trihalomethanes. Trihalomethanes are organic compounds in which exactly three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Trace amounts of 1,2-dibromoethane occur naturally in the ocean, where it is formed probably by algae and kelp. Bromoform is formally rated as an unfounded non-carcinogenic (IARC 3) potentially toxic compound. Exposure to bromoform may occur from the consumption of chlorinated drinking water. The acute (short-term) effects from inhalation or ingestion of high levels of bromoform in humans and animals consist of nervous system effects such as the slowing down of brain functions, and injury to the liver and kidney. Chronic (long-term) animal studies indicate effects on the liver, kidney, and central nervous system (CNS) from oral exposure to bromoform. Human data are considered inadequate in providing evidence of cancer by exposure to bromoform, while animal data indicate that long-term oral exposure can cause liver and intestinal tumors. Bromoform has been classified as a Group B2, probable human carcinogen. Most of the bromoform that enters the environment is formed as disinfection byproducts known as the trihalomethanes when chlorine is added to drinking water or swimming pools to kill bacteria. In the past, it was used as a solvent, sedative and flame retardant, but now it is mainly used as a laboratory reagent. Bromine is a halogen element with the symbol Br and atomic number 35. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock. Bromoform is a pale yellow liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform.

Bromodichloromethane

Bromodichloromethane, 14C-labeled

CHBrCl2 (161.8639)


Bromodichloromethane, also known as dichlorobromomethane or monobromodichloromethane, is classified as a member of the trihalomethanes. Trihalomethanes are organic compounds in which exactly three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Bromodichloromethane is a colorless, nonflammable liquid. Small amounts are formed naturally by algae in the oceans. Some of it will dissolve in water, but it readily evaporates into air. Only small quantities of bromodichloromethane are produced in the United States. The small quantities that are produced are used in laboratories or to make other chemicals. However, most bromodichloromethane is formed as a by-product when chlorine is added to drinking water to kill bacteria. Bromodichloromethane has been formerly used as a flame retardant, and a solvent for fats and waxes and because of its high density for mineral separation. Now it is only used as a reagent or intermediate in organic chemistry. Bromodichloromethane can also occur in municipally-treated drinking water as a by-product of the chlorine disinfection process.
