CYP2A6 is the primary enzyme responsible for the oxidation of nicotine and cotinine. It is also involved in the metabolism of several pharmaceuticals, carcinogens, and a number of coumarin-type alkaloids.

2024年12月24日 · CYP2A6 (Cytochrome P450 Family 2 Subfamily A Member 6) is a Protein Coding gene. Diseases associated with CYP2A6 include Tobacco Addiction and Coumarin Resistance. Among its related pathways are Oxidation by cytochrome P450 and Metapathway biotransformation Phase I and II.

The CYP2A6 genetic variants impact people's smoking habits, making it easier for some to quit smoking. Check your 23andMe or AncestryDNA genetic data.

As variation in CYP2A6 activity is associated with smoking behavior, smoking cessation, tobacco-related lung cancer risk, and with altered metabolism and resulting clinical responses for several therapeutics, CYP2A6 expression and enzyme activity is an important clinical consideration.

CYP2A6 is an hepatic enzyme predominantly with some expression in specialized extrahepatic cell types. The CYP2A6 enzyme has a somewhat restricted active site, accepting only a few xenobiotics as substrates.

Gene ID: 1548, updated on 8-Feb-2025. This gene, CYP2A6, encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids.

2012年5月5日 · CYP2A6 differs from other human liver CYP forms in that it participates in the metabolism of very few currently used drugs. The two most relevant substrates for CYP2A6 are coumarin and nicotine. Coumarin is the marker substance for determining CYP2A6 activity both in vitro and in vivo.

2012年6月1日 · CYP2A6 differs from other human liver CYP forms in that it participates in the metabolism of very few currently used drugs. The two most relevant substrates for CYP2A6 are coumarin and nicotine. Coumarin is the marker substance for determining CYP2A6 activity both in vitro and in vivo.

CYP2A6, a phase I drug metabolizing enzyme (DME) which metabolizes about 3% of pharmaceutical agents including letrozole, tegafur, coumarin, valproic acid, methoxyflurane, artesunate, disulfiram, halothane and fadrozole. Additionally, it also metabolizes nicotine, retinoic acids, environmental toxins, procarcinogens and steroids.
