CONCLUSIONS: Fluorophenylpiperazine, methoxyphenylpiperazine, chlorophenylpiperazine, methylbenzylpiperazine and methylenedioxybenzylpiperazine had significant inhibitory effects on CYP2D6, CYP1A2, CYP3A4, CYP2C19 and CYP2C9 isoenzymes but each piperazine had a different inhibitory profile.

Moreover, the formation of N-desmethylperazine also correlated well with S-mephenytoin 4'-hydroxylase activity (CYP2C19). alpha-Naphthoflavone (a CYP1A2 inhibitor) and ketoconazole (a CYP3A4 inhibitor) significantly decreased the rate of perazine 5-sulphoxidation, while ticlopidine (a CYP2C19 inhibitor) strongly reduced the rate of perazine N-demethylation in human liver microsomes.

The role of specific isoforms in the conversion of SIL to its primary circulating metabolite, UK-103,320 (piperazine N-desmethyl sildenafil) in the mouse was also investigated using immunoinhibitory antibodies.
CYP2C expression was assessed by Western blot analysis in rat and mouse livers.
