From: Enantioselective metabolism of primaquine by human CYP2D6
Semi-quantitation of the human CYP2D6-catalyzed enantio-selective generation of quinone-imine derivative of dihydroxylated primaquine metabolites (A) RT 3.42 min metabolite and (B) RT 4.56 metabolite, identified as quinone-imines ( m/z 290) degradation product. Each point shows mean value ± S.D. (n = 4).
