Genetic Variants of Flavin-containing Monooxygenases : Consequences for Drug Metabolism


The metabolism of the anti-tubercular drug, thiacetazone (TAZ) by human FMOs in vitro and the disposition of TAZ in vivo in mice were studied. Reverse phase chromatography confirmed TAZ to be a substrate for human FMO1, FMO2.1 and FMO3 with the formation of TAZ-sulphinic acid and TAZ-carbodiimide via a TAZsulphenic acid intermediate. The products are the… (More)
