19904008 Wojcikowski J, Daniel WA: Perazine at therapeutic drug concentrations inhibits human cytochrome P450 isoenzyme 1A2 (CYP1A2) and caffeine metabolism--an in vitro study. Pharmacol Rep. 2009 Sep-Oct;61(5):851-8.

The aim of the present study was to estimate the inhibitory effect of perazine, a phenothiazine neuroleptic with piperazine structure in a side chain, on human CYP1A2 activity measured as a rate of caffeine 3-N- and 1-N-demethylation.

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.

In human liver microsomes, the formation of perazine metabolites correlated significantly with the level of CYP1A2 and ethoxyrezorufin O-deethylase activity, as well as with the level of CYP3A4 and cyclosporin A oxidase activity.

Studies using human CYPs showed that CYP1A2, CYP2D6 and CYP3A4 catalyzed TFMPP hydroxylation, with CYP2D6 being the most important enzyme accounting for about 81% of the net intrinsic clearance, calculated using the relative activity factor approach.

Inhibition experiments using anti-rat CYP1A1, CYP1A2, CYP2B1, CYP2C11, CYP2E1, CYP3A2, and CYP4A1 antisera indicated that CYP3A2 played the predominant role in the metabolism of YIC-C8-434 in rats.

Their metabolism involves the hepatic P450 enzymes CYP2D6, CYP1A2 and CYP3A4 resulting in inhibited metabolism of other drugs and medicines, as well as compromised metabolism in poor metabolisers for CYP2D6.
