Identification of a reactive metabolite of the mutagen, 2-amino-3-methylimidazolo(4,5-f)quinoline.

A reactive major metabolite of the mutagen, 2-amino-3-methylimidazolo [4, 5-f]-quinoline (IQ), by rat liver microsomes was 2-hydroxyamino-3-methylimidazolo [4, 5-f]-quinoline (N-OH-IQ). The synthesis and reaction with DNA of N-OH-IQ were discussed.
