Incubation of the tricyclic antidepressant desmethylimpramine (DMI) with rat liver or brain microsomes in the presence of NADPH or t-butyl-hydroperoxide (TBH) revealed different regiospecificities in the hydroxylation reactions between the tissues. In brain preparations 10-OH-DMI was formed in reactions supported by NADPH or TBH, whereas in the latter case also an unidentified metabolite could be detected. Inclusion of exogenous NADPH-cytochrome P450 reductase in the brain preparations caused a 10-fold higher rate of 10-hydroxylation but no 2-OH-DMI could be detected. By contrast, liver microsomal preparations in the presence of NADPH catalyzed formation of both 2- and 10-OH-DMI, whereas only 10-OH-DMI was formed in TBH-supported reactions. The results indicate that antidepressant drugs can be metabolized in brain with different stereospecificity as compared to liver.
