title: Formation of N-nitrosodiphenylamine from 1,1-diphenylhydrazine by rat liver microsomal preparations.
abstract: The present study provides the first evidence for in vitro metabolic conversion of a 1,1-disubstituted hydrazine to the corresponding nitrosamine. The study shows that superoxide radical which is generated by NADPH-cytochrome c reductase is involved in the oxidation of 1,1-diphenylhydrazine to N-nitrosodiphenylamine catalyzed by rat liver microsomes.
