The metabolism of dibenzylamine: identification of NN-dibenzylhydroxylamine as the major in vitro metabolic product from rabbit fortified hepatic homogenates.

A study of the in vitro metabolism of dibenzylamine with fortified rabbit liver 9000 g supernatant fractions has shown that N-oxidation is the major metabolic process. Of the total amount of dibenzylamine metabolized, 90% is converted to NN-dibenzylhydroxylamine. The primary amine, benzylamine, is formed to the extent of only 6% of total substrate metabolized. The identity of the major metabolite, NN-dibenzylhydroxylamine has been established by thin-layer chromatography, gas-liquid chromatography and combined gas-liquid chromatography-mass spectrometry.
