Microsomal epoxide hydrolase polymorphisms.
Microsomal epoxide hydrolase plays a dual role in the activation and detoxification of carcinogenic compounds. Two polymorphic sites have been described in exons 3 and 4 of the microsomal epoxide hydrolase gene that change tyrosine residue 113 to histidine (Tyr113His) and histidine 139 to arginine (His139Arg), respectively. The exon 3 polymorphism reduces enzyme activity by approximately 50%, w...
متن کاملOxetane Substrates of Human Microsomal Epoxide Hydrolase.
Oxetanyl building blocks are increasingly used in drug discovery because of the improved drug-like properties they confer on drug candidates, yet little is currently known about their biotransformation. A series of oxetane-containing analogs was studied and we provide the first direct evidence of oxetane hydrolysis by human recombinant microsomal epoxide hydrolase (mEH). Incubations with human ...
متن کاملDevelopment of metabolically stable inhibitors of Mammalian microsomal epoxide hydrolase.
The microsomal epoxide hydrolase (mEH) plays a significant role in the metabolism of xenobiotics such as polyaromatic toxicants. Additionally, polymorphism studies have underlined a potential role of this enzyme in relation to a number of diseases, such as emphysema, spontaneous abortion, eclampsia, and several forms of cancer. We recently demonstrated that fatty amides, such as elaidamide, rep...
متن کاملFunctional analysis of human microsomal epoxide hydrolase genetic variants.
Human microsomal epoxide hydrolase (EPHX1) is active in the metabolism of many potentially carcinogenic or otherwise genotoxic epoxides, such as those derived from the oxidation of polyaromatic hydrocarbons. EPHX1 is polymorphic and encodes allelic variation at least two amino acid positions, Y113H and H139R. In a number of recent molecular epidemiological investigations, EPHX1 polymorphism has...
متن کاملHuman microsomal epoxide hydrolase: 5'-flanking region genetic polymorphisms.
Microsomal epoxide hydrolase (mEH) catalyses the hydrolysis of xenobiotic epoxides, including various epoxide derivatives of the procarcinogenic polyaromatic hydrocarbons. Levels of mEH enzymatic activity among different cell types and between individuals within the population vary considerably. Genetic polymorphisms within the structural region of the human mEH gene exist and appear to contrib...
