Metabolic N-oxidation and ring-oxidation of carcinogenic arylamines by hepatic cytochromes P-450 are generally regarded as critical activation and detoxification pathways, respectively. Two arylamines with known human exposure, 4-aminobiphenyl (ABP) and 4,4'-methylene-bis(2-chloroaniline) (MOCA), have been examined as substrates for 10 different purified rat hepatic cytochromes P-450 and for human liver microsomal preparations from 22 individuals. Metabolites were analyzed by high-performance… CONTINUE READING
