It has a role as an antibacterial agent, an antineoplastic agent, a dermatologic drug and a plant metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of an azelaate(2-) and an azelaate. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is also produced by Malassezia furfur, also known as Pityrosporum ovale, which is a species of fungus that is normally found on human skin. Azelaic acid is effective against a number of skin conditions, such as mild to moderate acne, when applied topically in a cream formulation of 20\\\\\%. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear. Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. Azelaic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). The physiologic effect of azelaic acid is by means of Decreased Protein Synthesis, and Decreased Sebaceous Gland Activity. Azelaic Acid is a naturally occurring dicarboxylic acid produced by Malassezia furfur and found in whole grain cereals, rye, barley and animal products. Azelaic acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant activity. Azelaic acid is bactericidal against Proprionibacterium acnes and Staphylococcus epidermidis due to its inhibitory effect on the synthesis of microbial cellular proteins. Azelaic acid exerts its keratolytic and comedolytic effects by reducing the thickness of the stratum corneum and decreasing the number of keratohyalin granules by reducing the amount and distribution of filaggrin in epidermal layers. Azelaic acid also possesses a direct anti-inflammatory effect due to its scavenger activity of free oxygen radical. This drug is used topically to reduce inflammation associated with acne and rosacea. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley.

Azelaic acid (AZA) is a naturally occurring saturated nine-carbon dicarboxylic acid (COOH (CH2)7-COOH). It possesses a variety of biological actions both in vitro and in vivo. Interest in the biological activity of AZA arose originally out of studies of skin surface lipids and the pathogenesis of hypochromia in pityriasis versicolor infection. Later, it was shown that Pityrosporum can oxidize unsaturated fatty acids to C8-C12 dicarboxylic acids that are cornpetitive inhibitors of tyrosinase in vitro. Azelaic acid was chosen for further investigation and development of a new topical drug for treating hyperpigmentary disorders for the following reasons: it possesses a middle-range of antityrosinase activity, is inexpensive, and more soluble to be incorporated into a base cream than other dicarboxylic acids. Azelaic acid is another option for the topical treatment of mild to moderate inflammatory acne vulgaris. It offers effectiveness similar to that of other agents without the systemic side effects of oral antibiotics or the allergic sensitization of topical benzoyl peroxide and with less irritation than tretinoin. Azelaic acid is less expensive than certain other prescription acne preparations, but it is much more expensive than nonprescription benzoyl peroxide preparations. Whether it is safe and effective when used in combination with other agents is not known. (PMID: 7737781, 8961845). An alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. Plants biology In plants, azelaic acid serves as a "distress flare" involved in defense responses after infection.[7] It serves as a signal that induces the accumulation of salicylic acid, an important component of a plant's defensive response.[8] Human biology The mechanism of action in humans is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37.[9] Polymers and related materials Esters of this dicarboxylic acid find applications in lubrication and plasticizers. In lubricant industries it is used as a thickening agent in lithium complex grease. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which finds specialized uses as a plastic.[4] Medical Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.[10][11] It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth[clarification needed] of acne bacteria.[12] Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation.[11] It clears the bumps and swelling caused by rosacea. In topical pharmaceutical preparations and scientific research AzA is typically used in concentrations between 15\\\% and 20\\\% but some research demonstrates that in certain vehicle formulations the pharmaceutical effects of 10\\\% Azelaic acid has the potential to be fully comparable to that of some 20\\\% creams.[13] Acne treatment Azelaic acid is effective for mild to moderate acne when applied topically at a 15\\\%-20\\\% concentration.[14][15][16][17] In patients with moderate acne, twice daily application over 3 months of 20\\\% AzA significantly reduced the number of comedones, papules, and pustules;[18][19] at this strength, it’s considered to be as effective as benzoyl peroxide 5\\\%, tretinoin 0.05\\\%, erythromycin 2\\\%, and oral tetracycline at 500 mg-1000 mg.[20][21] In a comparative review of effects of topical AzA, Salicylic acid, Nicotinamide, Sulfur, Zinc, and alpha-hydroxy acid, AzA had more high-quality evidence of effectiveness than the rest.[22] Results can be expected after 4 weeks of twice-daily treatment. The effectiveness of long term use is unclear, but it’s been recommended that AzA be used for at least 6 months continuously for maintenance.[20] Whitening agent Azelaic acid is used for treatment of skin pigmentation, including melasma and postinflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone.[23] As a tyrosinase inhibitor,[5] azelaic acid reduces synthesis of melanin.[24] According to one report in 1988, azelaic acid in combination with zinc sulfate in vitro was found to be a potent (90\\\% inhibition) 5α-reductase inhibitor, similar to the hair loss drugs finasteride and dutasteride.[25] In vitro research during mid-1980s evaluating azelaic acid's depigmenting (whitening) capability concluded it is effective (cytotoxic to melanocytes) at only high concentrations.[26] A 1996 review claimed 20\\\% AzA is as potent as 4\\\% hydroquinone after a period of application of three months without the latter's adverse effects and even more effective if applied along with tretinoin for the same period of time.[27][19] Azelaic acid is a nine-carbon dicarboxylic acid. Azelaic acid has antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis through inhibition of microbial cellular prorein synthesis. Azelaic acid has hypopigmentation action resulting from its ability to scavenge free radicals[1][2]. Azelaic acid is a nine-carbon dicarboxylic acid.

Salicylic acid is a monohydroxybenzoic acid that is benzoic acid with a hydroxy group at the ortho position. It is obtained from the bark of the white willow and wintergreen leaves. It has a role as an antiinfective agent, an antifungal agent, a keratolytic drug, an EC 1.11.1.11 (L-ascorbate peroxidase) inhibitor, a plant metabolite, an algal metabolite and a plant hormone. It is a conjugate acid of a salicylate. It is a colorless solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid). It is a plant hormone. The name is from Latin salix for willow tree. It is an ingredient in some anti-acne products. Salts and esters of salicylic acid are known as salicylates. Salicylic acid modulates COX1 enzymatic activity to decrease the formation of pro-inflammatory prostaglandins. Salicylate may competitively inhibit prostaglandin formation. Salicylates antirheumatic (nonsteroidal anti-inflammatory) actions are a result of its analgesic and anti-inflammatory mechanisms. Salicylic acid works by causing the cells of the epidermis to slough off more readily, preventing pores from clogging up, and allowing room for new cell growth. Salicylic acid inhibits the oxidation of uridine-5-diphosphoglucose (UDPG) competitively with nicotinamide adenosine dinucleotide and noncompetitively with UDPG. It also competitively inhibits the transferring of glucuronyl group of uridine-5-phosphoglucuronic acid to the phenolic acceptor. The wound-healing retardation action of salicylates is probably due mainly to its inhibitory action on mucopolysaccharide synthesis. Salicylic acid is biosynthesized from the amino acid phenylalanine. In Arabidopsis thaliana, it can be synthesized via a phenylalanine-independent pathway. Salicylic acid is an odorless white to light tan solid. Sinks and mixes slowly with water.

Glycerate

C3H6O4 (106.0266)

Glyceric acid is a colourless syrupy acid, obtained from oxidation of glycerol. It is a compound that is secreted excessively in the urine by patients suffering from D-glyceric aciduria, an inborn error of metabolism, and D-glycerate anemia. Deficiency of human glycerate kinase leads to D-glycerate acidemia/D-glyceric aciduria. Symptoms of the disease include progressive neurological impairment, hypotonia, seizures, failure to thrive, and metabolic acidosis. At sufficiently high levels, glyceric 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. Glyceric 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 abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of untreated glyceric aciduria. 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. Elevated values may also be due to microbial sources such as yeast (Aspergillus, Penicillium, probably Candida) or due to dietary sources containing glycerol (glycerine). Glyceric acid is isolated from various plants (e.g. brassicas, pulses, and Vicia faba). A colorless syrupy acid, obtained from oxidation of glycerol. It is a compound that is secreted excessively in the urine by patients suffering from D-glyceric aciduria and D-glycerate anemia. Deficiency of human glycerate kinase leads to D-glycerate acidemia/D-glyceric aciduria. Symptoms of the disease include progressive neurological impairment, hypotonia, seizures, failure to thrive and metabolic acidosis.; Glyceric acid is a natural three-carbon sugar acid. Salts and esters of glyceric acid are known as glycerates. Glyceric acid is found in many foods, some of which are peanut, common grape, garden tomato (variety), and french plantain. Glyceric acid.

Glutathione

C10H17N3O6S (307.0838)

Glutathione is a compound synthesized from cysteine, perhaps the most important member of the bodys toxic waste disposal team. Like cysteine, glutathione contains the crucial thiol (-SH) group that makes it an effective antioxidant. There are virtually no living organisms on this planet-animal or plant whose cells dont contain some glutathione. Scientists have speculated that glutathione was essential to the very development of life on earth. glutathione has many roles; in none does it act alone. It is a coenzyme in various enzymatic reactions. The most important of these are redox reactions, in which the thiol grouping on the cysteine portion of cell membranes protects against peroxidation; and conjugation reactions, in which glutathione (especially in the liver) binds with toxic chemicals in order to detoxify them. glutathione is also important in red and white blood cell formation and throughout the immune system. glutathiones clinical uses include the prevention of oxygen toxicity in hyperbaric oxygen therapy, treatment of lead and other heavy metal poisoning, lowering of the toxicity of chemotherapy and radiation in cancer treatments, and reversal of cataracts. (http://www.dcnutrition.com/AminoAcids/) glutathione participates in leukotriene synthesis and is a cofactor for the enzyme glutathione peroxidase. It is also important as a hydrophilic molecule that is added to lipophilic toxins and waste in the liver during biotransformation before they can become part of the bile. glutathione is also needed for the detoxification of methylglyoxal, a toxin produced as a by-product of metabolism. This detoxification reaction is carried out by the glyoxalase system. Glyoxalase I (EC 4.4.1.5) catalyzes the conversion of methylglyoxal and reduced glutathione to S-D-Lactoyl-glutathione. Glyoxalase II (EC 3.1.2.6) catalyzes the hydrolysis of S-D-Lactoyl-glutathione to glutathione and D-lactate. GSH is known as a substrate in both conjugation reactions and reduction reactions, catalyzed by glutathione S-transferase enzymes in cytosol, microsomes, and mitochondria. However, it is also capable of participating in non-enzymatic conjugation with some chemicals, as in the case of n-acetyl-p-benzoquinone imine (NAPQI), the reactive cytochrome P450-reactive metabolite formed by acetaminophen, that becomes toxic when GSH is depleted by an overdose (of acetaminophen). glutathione in this capacity binds to NAPQI as a suicide substrate and in the process detoxifies it, taking the place of cellular protein thiol groups which would otherwise be covalently modified; when all GSH has been spent, NAPQI begins to react with the cellular proteins, killing the cells in the process. The preferred treatment for an overdose of this painkiller is the administration (usually in atomized form) of N-acetylcysteine, which is used by cells to replace spent GSSG and renew the usable GSH pool. (http://en.wikipedia.org/wiki/glutathione). Glutathione (GSH) - reduced glutathione - is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. [Wikipedia]. Glutathione is found in many foods, some of which are cashew nut, epazote, ucuhuba, and canada blueberry. Glutathione. CAS Common Chemistry.

It is also one of the degradation products of threonine. It can be converted into propionyl-CoA (and subsequently methylmalonyl CoA, which can be converted into succinyl CoA, a citric acid cycle intermediate), and thus enter the citric acid cycle. More specifically, 2-ketobutyric acid is a product of the lysis of cystathionine. 2-Oxobutanoic acid is a product in the enzymatic cleavage of cystathionine.

1,4-Dihydronicotinamide adenine dinucleotide

C21H29N7O14P2 (665.1248)

Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD+ and NADH (H for hydrogen) respectively. NADH is the reduced form of NAD+, and NAD+ is the oxidized form of NADH. NAD (or nicotinamide adenine dinucleotide) is used extensively in glycolysis and the citric acid cycle of cellular respiration. The reducing potential stored in NADH can be either converted into ATP through the electron transport chain or used for anabolic metabolism. ATP "energy" is necessary for an organism to live. Green plants obtain ATP through photosynthesis, while other organisms obtain it via cellular respiration. NAD is a coenzyme composed of ribosylnicotinamide 5-diphosphate coupled to adenosine 5-phosphate by a pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). NADP is formed through the addition of a phosphate group to the 2 position of the adenosyl nucleotide through an ester linkage. NADH is the reduced form of NAD+, and NAD+ is the oxidized form of NADH, A coenzyme composed of ribosylnicotinamide 5-diphosphate coupled to adenosine 5-phosphate by pyrophosphate linkage.

Butanal

C4H8O (72.0575)

Butanal, also known as butyral or butyl aldehyde, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. It is miscible with most organic solvents. Butanal exists in all living organisms, ranging from bacteria to humans. Upon prolonged exposure to air, butyraldehyde oxidizes to form butyric acid. Butanal is an apple, bready, and chocolate tasting compound. Outside of the human body, Butanal is found, on average, in the highest concentration within cow milk and carrots. Butanal has also been detected, but not quantified in several different foods, such as hard wheats, borages, ostrich ferns, skunk currants, and fennels. This could make butanal a potential biomarker for the consumption of these foods. The dominant technology involves the use of rhodium catalysts derived from the water-soluble ligand Tppts. Butyraldehyde is produced almost exclusively by the hydroformylation of propylene:CH3CHCH2 + H2 + CO → CH3CH2CH2CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl and later rhodium complexes of triphenylphosphine. At one time, it was produced industrially by the catalytic hydrogenation of crotonaldehyde, which is derived from acetaldehyde. Butyraldehyde can be produced by the catalytic dehydrogenation of n-butanol. This compound is the aldehyde derivative of butane. An aqueous solution of the rhodium catalyst converts the propylene to the aldehyde, which forms a lighter immiscible phase. About 6 billion kilograms are produced annually by hydroformylation. It is a colourless flammable liquid with an unpleasant smell. Occurs in essential oils, e.g. lavender, hopand is also present in apple, banana, blackberry, hog plum, wheat bread, malt whiskey, red or white wine, tea, toasted oat flakes and other foodstuffs.

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

Alpha ketoaldehydes are organic compounds containing an aldehyde substituted with a keto group on the adjacent carbon. Methylglyoxal is soluble (in water) and an extremely weak acidic compound (based on its pKa). Methylglyoxal can be found in a number of food items such as shiitake, yellow zucchini, roman camomile, and carob, which makes methylglyoxal a potential biomarker for the consumption of these food products. Methylglyoxal can be found primarily in blood and urine, as well as throughout most human tissues. Methylglyoxal exists in all living species, ranging from bacteria to humans. In humans, methylglyoxal is involved in few metabolic pathways, which include glycine and serine metabolism, pyruvaldehyde degradation, pyruvate metabolism, and spermidine and spermine biosynthesis. Methylglyoxal is also involved in several metabolic disorders, some of which include hyperglycinemia, non-ketotic, pyruvate kinase deficiency, non ketotic hyperglycinemia, and pyruvate decarboxylase E1 component deficiency (PDHE1 deficiency). Moreover, methylglyoxal is found to be associated with diabetes mellitus type 2. Methylglyoxal, also called pyruvaldehyde or 2-oxopropanal, is the organic compound with the formula CH3C(O)CHO. Gaseous methylglyoxal has two carbonyl groups, an aldehyde and a ketone but in the presence of water, it exists as hydrates and oligomers. It is a reduced derivative of pyruvic acid . Pyruvaldehyde is an organic compound used often as a reagent in organic synthesis, as a flavoring agent, and in tanning. It has been demonstrated as an intermediate in the metabolism of acetone and its derivatives in isolated cell preparations, in various culture media, and in vivo in certain animals.

Carbon dioxide

CO2 (43.9898)

Carbon dioxide is a colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. Carbon dioxide is produced during respiration by all animals, fungi and microorganisms that depend on living and decaying plants for food, either directly or indirectly. It is, therefore, a major component of the carbon cycle. Additionally, carbon dioxide is used by plants during photosynthesis to make sugars which may either be consumed again in respiration or used as the raw material to produce polysaccharides such as starch and cellulose, proteins and the wide variety of other organic compounds required for plant growth and development. When inhaled at concentrations much higher than usual atmospheric levels, it can produce a sour taste in the mouth and a stinging sensation in the nose and throat. These effects result from the gas dissolving in the mucous membranes and saliva, forming a weak solution of carbonic acid. Carbon dioxide is used by the food industry, the oil industry, and the chemical industry. Carbon dioxide is used to produce carbonated soft drinks and soda water. Traditionally, the carbonation in beer and sparkling wine comes about through natural fermentation, but some manufacturers carbonate these drinks artificially. Leavening agent, propellant, aerating agent, preservative. Solvent for supercritical extraction e.g. of caffeine in manufacture of caffeine-free instant coffee. It is used in carbonation of beverages, in the frozen food industry and as a component of controlled atmosphere packaging (CAD) to inhibit bacterial growth.

Formic acid

CH2O2 (46.0055)

Formic acid is the simplest carboxylic acid. Formate is an intermediate in normal metabolism. It takes part in the metabolism of one-carbon compounds and its carbon may appear in methyl groups undergoing transmethylation. It is eventually oxidized to carbon dioxide. Formate is typically produced as a byproduct in the production of acetate. It is responsible for both metabolic acidosis and disrupting mitochondrial electron transport and energy production by inhibiting cytochrome oxidase activity, the terminal electron acceptor of the electron transport chain. Cell death from cytochrome oxidase inhibition by formate is believed to result partly from depletion of ATP, reducing energy concentrations so that essential cell functions cannot be maintained. Furthermore, inhibition of cytochrome oxidase by formate may also cause cell death by increased production of cytotoxic reactive oxygen species (ROS) secondary to the blockade of the electron transport chain. In nature, formic acid is found in the stings and bites of many insects of the order Hymenoptera, including bees and ants. The principal use of formic acid is as a preservative and antibacterial agent in livestock feed. When sprayed on fresh hay or other silage, it arrests certain decay processes and causes the feed to retain its nutritive value longer. Urinary formate is produced by Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterobacter, Acinetobacter, Proteus mirabilis, Citrobacter frundii, Enterococcus faecalis, Streptococcus group B, Staphylococcus saprophyticus (PMID: 22292465). It is used as a flavouring adjunct, an animal feed additive, a brewing antiseptic and as a food preservative

Formaldehyde

CH2O (30.0106)

Formaldehyde is a highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717) -- Pubchem; The chemical compound formaldehyde (also known as methanal), is a gas with a pungent smell. It is the simplest aldehyde. Its chemical formula is H2CO. Formaldehyde was first synthesized by the Russian chemist Aleksandr Butlerov in 1859 but was conclusively identified by August Wilhelm van Hofmann in 1867. Although formaldehyde is a gas at room temperature, it is readily soluble in water, and it is most commonly sold as a 37\\% solution in water called by trade names such as formalin or formol. In water, formaldehyde polymerizes, and formalin actually contains very little formaldehyde in the form of H2CO monomer. Usually, these solutions contain a few percent methanol to limit the extent of polymerization. Formaldehyde exhibits most of the general chemical properties of the aldehydes, except that is generally more reactive than other aldehydes. Formaldehyde is a potent electrophile. It can participate in electrophilic aromatic substitution reactions with aromatic compounds and can undergo electrophilic addition reactions with alkenes. In the presence of basic catalysts, formaldehyde undergoes a Cannizaro reaction to produce formic acid and methanol. Because formaldehyde resins are used in many construction materials, including plywood, carpet, and spray-on insulating foams, and because these resins slowly give off formaldehyde over time, formaldehyde is one of the more common indoor air pollutants. At concentrations above 0.1 mg/kg in air, inhaled formaldehyde can irritate the eyes and mucous membranes, resulting in watery eyes, headache, a burning sensation in the throat, and difficulty breathing. -- Wikipedia. A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. Formaldehyde is found in many foods, some of which are ginseng, lentils, coriander, and allspice.

Acetaldehyde

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. Flavouring agent and adjuvant used to impart orange, apple and butter flavours; component of food flavourings added to milk products, baked goods, fruit juices, candy, desserts and soft drinks [DFC]

Tetrahydrofolic acid

C19H23N7O6 (445.171)

Tetrahydrofolate is a soluble coenzyme (vitamin B9) that is synthesized de novo by plants and microorganisms, and absorbed from the diet by animals. It is composed of three distinct parts: a pterin ring, a p-ABA (p-aminobenzoic acid) and a polyglutamate chain with a number of residues varying between 1 and 8. Only the tetra-reduced form of the molecule serves as a coenzyme for C1 transfer reactions. In biological systems, the C1-units exist under various oxidation states and the different tetrahydrofolate derivatives constitute a family of related molecules named indistinctly under the generic term folate. (PMID 16042593). Folate is important for cells and tissues that rapidly divide. Cancer cells divide rapidly, and drugs that interfere with folate metabolism are used to treat cancer. Methotrexate is a drug often used to treat cancer because it inhibits the production of the active form, tetrahydrofolate. Unfortunately, methotrexate can be toxic, producing side effects such as inflammation in the digestive tract that make it difficult to eat normally. -- Wikipedia; Signs of folic acid deficiency are often subtle. Diarrhea, loss of appetite, and weight loss can occur. Additional signs are weakness, sore tongue, headaches, heart palpitations, irritability, and behavioral disorders. Women with folate deficiency who become pregnant are more likely to give birth to low birth weight and premature infants, and infants with neural tube defects. In adults, anemia is a sign of advanced folate deficiency. In infants and children, folate deficiency can slow growth rate. Some of these symptoms can also result from a variety of medical conditions other than folate deficiency. It is important to have a physician evaluate these symptoms so that appropriate medical care can be given. -- Wikipedia; Folinic acid is a form of folate that can help rescue or reverse the toxic effects of methotrexate. Folinic acid is not the same as folic acid. Folic acid supplements have little established role in cancer chemotherapy. There have been cases of severe adverse effects of accidental substitution of folic acid for folinic acid in patients receiving methotrexate cancer chemotherapy. It is important for anyone receiving methotrexate to follow medical advice on the use of folic or folinic acid supplements. -- Wikipedia. Low concentrations of folate, vitamin B12, or vitamin B6 may increase the level of homocysteine, an amino acid normally found in blood. There is evidence that an elevated homocysteine level is an independent risk factor for heart disease and stroke. The evidence suggests that high levels of homocysteine may damage coronary arteries or make it easier for blood clotting cells called platelets to clump together and form a clot. However, there is currently no evidence available to suggest that lowering homocysteine with vitamins will reduce your risk of heart disease. Clinical intervention trials are needed to determine whether supplementation with folic acid, vitamin B12 or vitamin B6 can lower your risk of developing coronary heart disease. -- Wikipedia.

Pyrroloquinoline quinone

C14H6N2O8 (330.0124)

Enzymes containing PQQ are called quinoproteins. PQQ and quinoproteins play a role in the redox metabolism and structural integrity of cells and tissues [PMID:2558842]. It was reported that aminoadipate semialdehyde dehydrogenase (AASDH) might also use PQQ as a cofactor, suggesting a possibility that PQQ is a vitamin in mammals. [PMID:12712191]. Believed to be a mammalian redox-cofactor vitamin (B group). Widely distributed in various foods such as vegetables and meat. Methoxatin is found in animal foods and green vegetables. Pyrroloquinoline quinone (PQQ), a redox co-factor, is an anionic, redox-cycling orthoquinone. Pyrroloquinoline quinone is isolated from cultures of methylotropic bacteria and tissues of mammals. Pyrroloquinoline quinone is an essential nutrient for mammals and is important for immune function[1][2].

Methanol

CH4O (32.0262)

Methanol, also known as columbian spirit or CH3OH, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds comprising the primary alcohol functional group, with the general structure RCOH (R=alkyl, aryl). The target of methanol in the eye is the retina, specifically the optic disk and optic nerve. Toxicity is due to the metabolic products of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase. Methanol exists in all living organisms, ranging from bacteria to humans. Methanol is an alcoholic tasting compound. Outside of the human body, Methanol is found, on average, in the highest concentration within cow milk and sweet oranges. Methanol has also been detected, but not quantified in several different foods, such as prairie turnips, mountain yams, mentha (mint), watermelons, and pasta. Methanol is responsible for accidental, suicidal, and epidemic poisonings, resulting in death or permanent sequelae. Methanol is a potentially toxic compound. Visual disturbances develop between 18h to 48h after ingestion and range from mild photophobia and blurred vision to markedly reduced visual acuity and complete blindness. Methanol is metabolized to formaldehyde by alcohol dehydrogenase, then from that to formate by formaldehyde dehydrogenase, and then to carbon dioxide by limited H4 folate. It is the simplest alcohol, and is a light, volatile, colourless, flammable, poisonous liquid with a distinctive odor that is somewhat milder and sweeter than ethanol. Present in various wines and spirits. It is used as a solvent for the preparation of modified hop extracts and spice oleoresins D012997 - Solvents

C3H6O3 (90.0317)

Dihydroxyacetone, also known as 1,3-dihydroxy-2-propanone or glycerone, is a member of the class of compounds known as monosaccharides. Monosaccharides are compounds containing one carbohydrate unit not glycosidically linked to another such unit, and no set of two or more glycosidically linked carbohydrate units. Monosaccharides have the general formula CnH2nOn. Dihydroxyacetone is soluble (in water) and a very weakly acidic compound (based on its pKa). Dihydroxyacetone can be found in a number of food items such as cauliflower, green bell pepper, black cabbage, and sweet basil, which makes dihydroxyacetone a potential biomarker for the consumption of these food products. Dihydroxyacetone can be found primarily in urine, as well as in human muscle and stratum corneum tissues. Dihydroxyacetone exists in all living species, ranging from bacteria to humans. Dihydroxyacetone is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin . Dihydroxyacetone (also known as DHA) is a ketotriose compound. Its addition to blood preservation solutions results in better maintenance of 2,3-diphosphoglycerate levels during storage. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones, it acts as a sunscreening agent. Dihydroxyacetone is the simplest of all ketoses and, having no chiral centre, is the only one that has no optical activity. Dihydroxyacetone is a simple non-toxic sugar. It is often derived from plant sources such as sugar beets and sugar cane, by the fermentation of glycerin. Dihydroxyacetone is a white crystalline powder which is water soluble. 1,3-Dihydroxyacetone (DHA), the main active ingredient in sunless tanning skin-care preparations and an important precursor for the synthesis of various fine chemicals, is produced on an industrial scale by microbial fermentation of glycerol over Gluconobacter oxydans[1]. 1,3-Dihydroxyacetone (DHA), the main active ingredient in sunless tanning skin-care preparations and an important precursor for the synthesis of various fine chemicals, is produced on an industrial scale by microbial fermentation of glycerol over Gluconobacter oxydans[1].

Methylamine

CH5N (31.0422)

Methylamine occurs endogenously from amine catabolism and its tissue levels increase in some pathological conditions, including diabetes. Interestingly, methylamine and ammonia levels are reciprocally controlled by a semicarbazide-sensitive amine oxidase activity that deaminates methylamine to formaldehyde with the production of ammonia and hydrogen peroxide. Methylamine also targets the voltage-operated neuronal potassium channels, probably inducing release of neurotransmitter(s). Semicarbazide-sensitive amine oxidase (SSAO) catalyzes the deamination of primary amines. Such deamination has been shown capable of regulating glucose transport in adipose cells. It has been independently discovered that the primary structure of vascular adhesion protein-1 (VAP-1) is identical to SSAO. Increased serum SSAO activities have been found in patients with diabetic mellitus, vascular disorders, and Alzheimers disease. The SSAO-catalyzed deamination of endogenous substrates like methylamine led to production of toxic formaldehyde. Chronic elevated methylamine increases the excretion of malondialdehyde and microalbuminuria. Amine oxidase substrates such as methylamine have been shown to stimulate glucose uptake by increasing the recruitment of the glucose transporter GLUT4 from vesicles within the cell to the cell surface. Inhibition of this effect by the presence of semicarbazide and catalase led to the suggestion that the process is mediated by the hydrogen peroxide produced in the oxidation of these amines (PMID: 16049393 , 12686132 , 17406961). Methylamine has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Methylamine is a colourless gas derivative of ammonia, but with one H atom replaced by a methyl group. It is the simplest primary amine. It has a strong odor similar to fish. Methylamine is used as a building block for the synthesis of many other commercially available compounds. Hundreds of millions of kilograms are produced annually. Methylamine is found in many foods, some of which are french plantain, tea, barley, and wild celery.

Cyclohexanone

C6H10O (98.0732)

Cyclohexanone is a food flavourant. Present in various plant spp. e.g. Cistus ladaniferus (labdanum). Cyclohexanone is a colorless oily liquid with an odor resembling acetone and peppermint. Cyclohexanone is occasionally found as a volatile component of human urine. Biological fluids such as blood and urine have been shown to contain a large number of components, some of them volatiles (low boiling point) apparently present in all individuals, while others such are much more variable. In some cases differences up to an order of magnitude are observed. Although some of these changes may have dietary origins, others seem to be characteristic of the individual. Cyclohexanone is obtained through oxidation of cyclohexane or dehydrogenation of phenol. Approx. 95\\% of its manuf. is used for the production of nylon. Information on toxicity to human beings is fragmentary. Acute exposure is characterized by irritation of the eyes, nose, and throat. In two persons, drowsiness and renal impairment were found; Like cyclohexanol, cyclohexanone is not carcinogenic and is only moderately toxic, with a TLV of 25 ppm for the vapor. It is an irritant.; The great majority of cyclohexanone is consumed in the production of precursors to Nylon 66 and Nylon 6. About half of the worlds supply is converted to adipic acid, one of two precursors for nylon 66. For this application, the KA oil (see above) is oxidized with nitric acid. The other half of the cyclohexanone supply is converted to the oxime. In the presence of sulfuric acid catalyst, the oxime rearranges to caprolactam, a precursor to nylon 6:; however, there were embryotoxic effects and influence on reproduction Cyclohexanone is well absorbed through the skin, respiratory tract, and alimentary tract. The main metabolic pathway leads to cyclohexanol, which is excreted in urine coupled with glucuronic acid. A high correlation was found between the concentration of cyclohexanone in the working environment and its concentration in urine. Cyclohexanone is formed from the hydrocarbons cyclohexane and 1-, 2-, and 3-hexanol. A patients case report documents the development of anosmia (an olfactory disorder) and rhinitis caused by occupational exposure to organic solvents, including cyclohexanone (PMID: 10476412, 16925936, 16477465); however, these workers were also exposed to other compounds. Hepatic disorders were found in a group of workers exposed for over five years. In animals, cyclohexanone is characterized by relatively low acute toxicity (DL50 by intragastric administration is approx. 2 g/kg body wt.). Effects on the central nervous system (CNS) were found (narcosis), as well as irritation of the eyes and skin. Following multiple administration, effects were found in the CNS, liver, and kidneys as well as irritation of the conjunctiva.

C11H17N3O7S (335.0787)

S-Formylglutathione, also known as L-gamma-glutamyl-S-formyl-L-cysteinylglycine, belongs to the class of organic compounds known as oligopeptides. These are organic compounds containing a sequence of three to ten alpha-amino acids joined by peptide bonds. S-Formylglutathione is a very strong basic compound (based on its pKa). S-Formylglutathione exists in all living species, ranging from bacteria to humans. Outside of the human body, S-formylglutathione has been detected, but not quantified in, several different foods, such as sweet marjorams, muscadine grapes, amaranths, lemon verbena, and garden tomato. This could make S-formylglutathione a potential biomarker for the consumption of these foods. S-Formylglutathione is formed from the oxidation of S-hydroxymethylglutathione by the enzyme formaldehyde dehydrogenase (FDH; EC 1.2.1.1) in the presence of NAD (PMID: 2806555). S-Formylglutathione is formed from the oxidation of S-hydroxymethylglutathione by the enzyme formaldehyde dehydrogenase (FDH; EC 1.2.1.1) in the presence of NAD (PubMed ID 2806555) [HMDB]. S-Formylglutathione is found in many foods, some of which are horseradish tree, wild carrot, japanese walnut, and red beetroot.

Hexanal

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.

Tetradecanoyl-CoA

C35H62N7O17P3S (977.3136)

Tetradecanoyl-CoA (or myristoyl-CoA) is an intermediate in fatty acid biosynthesis, fatty acid elongation and the beta oxidation of fatty acids. It is also used in the myristoylation of proteins. The first pass through the beta-oxidation process starts with the saturated fatty acid palmitoyl-CoA and produces myristoyl-CoA. A total of four enzymatic steps are required, starting with VLCAD CoA dehydrogenase (Very Long Chain) activity, followed by three enzymatic steps catalyzed by enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and ketoacyl-CoA thiolase, all present in the mitochondria. Myristoylation of proteins is also catalyzed by the presence of myristoyl-CoA along with Myristoyl-CoA:protein N-myristoyltransferase (NMT). Myristoylation is an irreversible, co-translational (during translation) protein modification found in animals, plants, fungi and viruses. In this protein modification a myristoyl group (derived from myristioyl CoA) is covalently attached via an amide bond to the alpha-amino group of an N-terminal amino acid of a nascent polypeptide. It is more common on glycine residues but also occurs on other amino acids. Myristoylation also occurs post-translationally, for example when previously internal glycine residues become exposed by caspase cleavage during apoptosis. Myristoylation plays a vital role in membrane targeting and signal transduction in plant responses to environmental stress. Compared to other species that possess a single functional myristoyl-CoA: protein N-myristoyltransferase (NMT) gene copy, human, mouse and cow possess 2 NMT genes, and more than 2 protein isoforms. Myristoyl-coa, also known as S-tetradecanoyl-coenzyme a or myristoyl-coenzyme a, is a member of the class of compounds known as long-chain fatty acyl coas. Long-chain fatty acyl coas are acyl CoAs where the group acylated to the coenzyme A moiety is a long aliphatic chain of 13 to 21 carbon atoms. Myristoyl-coa is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Myristoyl-coa can be found in a number of food items such as sea-buckthornberry, anise, chicory, and cassava, which makes myristoyl-coa a potential biomarker for the consumption of these food products. Myristoyl-coa can be found primarily in human fibroblasts tissue. Myristoyl-coa exists in all eukaryotes, ranging from yeast to humans. In humans, myristoyl-coa is involved in few metabolic pathways, which include adrenoleukodystrophy, x-linked, beta oxidation of very long chain fatty acids, and fatty acid metabolism. Myristoyl-coa is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis TG(18:0/14:0/22:0), de novo triacylglycerol biosynthesis tg(i-21:0/12:0/14:0), de novo triacylglycerol biosynthesis TG(18:1(9Z)/14:0/22:2(13Z,16Z)), and de novo triacylglycerol biosynthesis TG(14:0/16:1(9Z)/22:5(4Z,7Z,10Z,13Z,16Z)).

3,4-Dihydroxyphenylacetaldehyde

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.

Selenocystine

C6H12N2O4Se2 (335.9127)

Selenocystine, also known as 3,3-diselenodialanine, belongs to the class of organic compounds known as alpha-amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxyl group (alpha carbon). More specifically, selenocystine is a diselenide consisting of two selenoamino acids that are attached together at their selenium atoms. This particular selenoamino acid is selenocysteine, the selenium analogue to cysteine (selenium being the element directly beneath sulphur in the periodic table); likewise, selenocystine is the selenium analogue to cystine. Since each constituent amino acid has a stereocentre, there are three different stereoisomers of selenocystine: D-selenocystine, L-selenocystine, and meso-selenocystine, the first two of which are optically active. Like other amino acids, L-selenocystine is the most common form within organisms; however, the D- and meso- forms have also been found (PMID: 30920149). Selenocystine is a solid that is moderately soluble in water. Due to the reactivity of selenocysteine, it is rarely encountered; rather, cells store selenium in the less reactive oxidized form of selenocystine or in a methylated form, such as selenomethionine (DOI: 10.1007/978-3-319-92405-2_3). When cells are grown in the absence of selenium, translation of selenoproteins terminates at the UGA codon, resulting in a truncated, non-functional enzyme. Unlike other amino acids present in biological proteins, selenocysteine is not coded for directly in the genetic code. Rather, the tRNA-bound seryl residue is converted to a selenocysteine residue by the pyridoxal phosphate-containing enzyme selenocysteine synthase (PMID: 17194211). Kurt Franke et al. indicated that there was evidence that selenium was in a form similar to that of cysteine, predating Thressa Stadtman’s discovery of the 21st amino acid by four decades (PMID: 26949981; J. Biol. Chem. 111:643). Selenocysteine may be denoted by the short forms Sec, U, or SeCys (Cys is used for cysteine), whereas selenocystine may be denoted by SeCys2. However, the literature sometimes uses SeCys for selenocystine and may cause confusion. Selenocystine has been found in animals, plants, and bacteria. It is being researched as treatment for cancer and for its antioxidant properties (PMID: 24763048, 24030774). Selenium, in its various forms such as selenocystine, is essential for many species, including humans, yet it is also toxic to all organisms; hence, it has come to be referred to as the “essential poison” (PMID: 26949981; 6679541). Selenocystine is a substrate for glutathione peroxidase 1. [HMDB] D000890 - Anti-Infective Agents > D000998 - Antiviral Agents L-Selenocystine is a diselenide-bridged amino acid. L-Selenocystine is a redox-active selenium compound that has both anti- and pro-oxidant actions. L-Selenocystine induces an unfolded protein response, ER stress, and large cytoplasmic vacuolization in HeLa cells and has cytostatic effects in a range of cancer cell types[1].

Chloroacetaldehyde

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.

4-Hydroxycyclophosphamide

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.

Bromodichloromethane

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.
