Abstract excerpt
In human liver microsomes the oxidations of benzene, chlorzoxazone, aniline, dimethylformamide, and 4-nitrophenol were significantly correlated with each other and with the level of cytochrome P450 (CYP) 2E1 estimated by immunoblotting. Moreover, benzene oxidation to water-soluble metabolites was suppressed by 0.1 mM diethyldithiocarbamate, supposedly a specific inhibitor of CYP2E1 at this level. None of these...
