HIDE SMILES / InChI
Z-N-desmethyldoxepin is an active metabolite of doxepin, a tricyclic antidepressant. Z-N-desmethyldoxepin appeared to be a terminal oxidative metabolite, in comparison with isomeric form E-N-desmethyl-doxepin, which is undergone further oxidation under the action of CYP2D6 activity.

In 'metabolic consumption' experiments with liver microsomes (having measurable CYP2D6 activity) and initial substrate concentration of 1 microM, the consumption of E-doxepin was greater than that of Z-doxepin. With N-desmethyldoxepin, quinidine inhibited the consumption of E-N-desmethyl-doxepin whereas Z-N-desmethyldoxepin appeared to be a terminal oxidative metabolite. CYP2D6 is a major oxidative enzyme in doxepin metabolism; predominantly catalysing hydroxylation with an exclusive preference for the E-isomers. The relatively more rapid metabolism of E-isomeric forms, and the limited metabolic pathways for the Z-isomers explained the apparent enrichment of Z-N-desmethyldoxepin.
