PPIF

(redirected from CYP3)

PPIF

A gene on chromosome 10q22-q23 that encodes peptidylprolyl cis-trans isomerase F (cyclophilin F), which, as with other PPIs, accelerates protein folding. It catalyses the cis-trans isomerisation of proline-imidic peptide bonds in oligopeptides.

Of these the most important for drug clearance belong to the CYP1, CYP2, and CYP3 families (31).

There are three major CYP families that encode enzymes that play an important role in phase I metabolism: CYP1, CYP2, and CYP3. (3) The CYP3A subfamily is the most abundant CYP enzyme and represents about 30% of the total CYP in the human liver.

In animal studies, it has been found that IH-induced liver damage affects the rate of drug metabolism, such as that of theophylline, which is widely used for treating respiratory system diseases.[24] In humans, the CYP1, CYP2, and CYP3 families are involved in hepatic drug metabolism.

On the other hand, apixaban and phenytoin share the hepatic enzyme CYP3 A4, and their concurrent use will lower its effectiveness (Lehne, 2013).

Oral anticoagulants: the move beyond warfarin

In addition to P-gp, Caco-2 cells express the metabolizing enzyme CYP3A and nuclear receptors such as pregnane X receptor (PXR), which regulate the expression of ABCB1 and CYP3. P-gp and CYP3A interact co-ordinately at the intestinal barrier and limit drug absorption.

Over 70 CYP gene families have been described so far and are further divided into families and subfamilies of which CYP1, CPY2 and CYP3, are involved in hepatic drug metabolism.

Those most important in drug metabolism are CYP1, CYP2 and CYP3; out of these, six enzymes are responsible for the biotransformation of more than 90 percent of drugs undergoing phase I metabolism (see table 1, p22).

Metabolism and excretion: eliminating drugs from the body

Coadministering a cytochrome P450 isoenzyme 3A4 (CYP3A4)inhibiting macrolide antibiotic, such as clarithromycin or erythromycin) (but not azithromycin) with atorvastatin (Lipitor[R]), simvastatin (Zocor[R]), or lovastatin (Mevacor[R]), which are metabolized by CYP3 A4, is associated with a fourfold to 10-fold increase in statin concentrations.
