degradation product

Orlistat degradation product is a degradation product of the digestive lipase inhibitor orlistat . It is formed via hydrolytic and thermal degradation as well as digestion by human carboxyl ester lipase.

Penicillamine (Artamine), possessing antineoplastic properties, induces apoptosis by a p53-mediated mechanism and inhibits angiogenesis by chelating with copper, a cofactor for angiogenesis. Artamine is a beta dimethyl analog of the amino acid cysteine. As a degradation product of penicillin antibiotics, Artamine chelates with heavy metals and increases their urinary excretion.

Erythromycin A enol ether is a degradation product of Erythromycin A which is a macrolide antibiotic.

DP-1 hydrochloride is a degradation product of SDC-TRAP-0063, a fragment of Ganetespib, a heat shock protein 90 (HSP90) inhibitor with antitumor activity.

Xanthine (Isoxanthine) is a product on the pathway of purine degradation. Xanthine is subsequently converted to uric acid by the action of the Xanthine oxidase enzyme. Xanthine is found in most body tissues and fluids in various organisms. Biologically Xanthine is produced from guanine by cypin (guanine deaminase). Furthermore, Xanthines act as antagonists for adenosine receptors, with selectivity depending on whether there are substitution of alkyl groups.

DL-Penicillamine (3-Sulfanylvaline) is a chelating agent recommended for the removal of excess copper in patients with Wilson's disease. DL-Penicillamine is only found in individuals that have used or taken this drug. It is the most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilson's disease. From in vitro studies which indicate that one atom of copper combines with two molecules of DL-penicillamine. DL-Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between DL-penicillamine and cystine, resulting in the formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cysteine and is excreted readily. DL-Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of DL-penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, DL-penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, DL-penicillamine in vitro depresses T-cell activity but not B-cell activity.

Bromelain is an anti-inflammatory drug derived from pineapple stem. It acts through down-regulation of plasma kininogen, degradation of advanced glycation end-product receptors, inhibition of Prostaglandin E2 expression, and regulation of angiogenic bioma

3-Formyl rifamycin is a degradation product of Rifampicin, with antibacterial activity.

Ketoisophorone (2,6,6-Trimethyl-2-cyclohexene-1,4-dione) is the major ingredients of saffron spice. It is a cyclic olefin and was reported as a product of the thermal degradation of β-carotene in aqueous suspension.

N4-Acetylcytidine (N-Acetylcytidine) is a modified nucleoside. N4-acetylcytidine is an endogenous urinary nucleoside product of the degradation of transfer ribonucleic acid (tRNA); urinary nucleosides are biological markers for patients with colorectal cancer.

Pyrrole-2-carboxylic acid (Minaline) was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A'-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) ' was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

Indole has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. It can be produced by bacteria as a degradation product of the amino acid tryptophan. It occurs naturally in human feces and has an intense fecal smell. At very low concentrations, however, it has a flowery smell, and is a constituent of many flower scents (such as orange blossoms) and perfumes.

N-Methylhydantoin (1-Methyl-hydantoin) is a small molecular weight polar substance, the product of degradation of creatinine by bacteria. In mammals, the Metabolism of N-Methylhydantoin occurs via 5-hydroxy-1-methylhydantoin. In a reported human case,N-Methylhydantoin was found as an unexpected metabolite of the intelligence-affecting substance dupracetam.

3-hydroxybutyric acid is involved in the synthesis and degradation of ketone bodies. Like the other ketone bodies (acetoacetate and acetone), levels of beta-hydroxybutyrate are raised in the blood and urine in ketosis. Beta-hydroxybutyrate is a typical pa

Raspberry ketone glucoside, a natural compound found in raspberry fruit, exhibits prolonged inhibition of melanogenesis and various melanogenic factors following its degradation in the skin.

N6-Methyladenosine is a methylated adenine residue, glycoside is an endogenous uridine product of transfer RNA degradation. It is the most prevalent internal modification of messenger RNA present in all higher eukaryotes and can modify viral RNA with antiviral activity.

3-Amino-2-methylpropanoic acid (α-Methyl-β-alanine) is the product from the conversion of N-carbamyl-beta-aminoisobutyric acid by the enzyme Beta-ureidopropionase (EC 3.5.1.6), the last step in pyrimidine degradation. Beta-ureidopropionase deficiency is an inborn error of pyrimidine degradation associated with neurological abnormalities.

p,p'-DDE (p,p'-dichlorodiphenyldichloroethylene) is a metabolite and degradation product of the organochlorine pesticide DDT

Atorvastatin Epoxy Tetrahydrofuran Impurity is an isolated oxidative degradation product of Atorvastatin, an orally active HMG-CoA reductase inhibitor.
