  • Title: Role of mixed-function amine oxidases in N-hydroxylation of 2-acetamidofluorene by hamster liver microsomal preparations.
    Author: Lotlikar PD, Wertman K, Luha L.
    Journal: Biochem J; 1973 Dec; 136(4):1137-40. PubMed ID: 4150650.
    Abstract:
    Pretreatment of hamsters with 3-methylcholanthrene (100mg/kg body wt.) 24h before death did not appreciably change the extent of N-oxide formation when hepatic microsomal preparations were incubated with NN-dimethylaniline as substrate. In contrast, the N-hydroxylation of 2-acetamidofluorene was increased severalfold in hepatic microsomal preparations from pretreated animals. Under these conditions there were no appreciable changes in cytochrome P-450 content and NADPH-cytochrome c reductase activity. On the basis of these comparative data, it is suggested that amine oxidase is not involved in N-hydroxylation of 2-acetamidofluorene.
