Działania biochem./fizjol.
Cytochrome P450 is a heterogeneous family of isozymes whose primary function is to oxidize small molecules, both as a function of intermediary metabolism (e.g., fatty acids) and to detoxify exogenous compounds (drugs or toxins). Some isoforms have narrow substrate specificity, while others are promiscuous. The CYP1A1 isoform catalyzes 7-deethylation of ethoxyresorufin. Cytochrome P450 (CYP) plays an important role in detoxifying xenobiotics, cellular metabolism and homeostasis. One of the main mechanisms of drug-drug interactions is the induction or inhibition of these enzymes. CYP enzymes are transcriptionally activated by a variety of xenobiotics and by endogenous substrates via receptor-dependent pathways. Inhibition of these enzymes is a major factor in metabolism-based drug-drug interactions, and many chemotherapeutic medications can cause drug interactions by either inhibiting or inducing the cytochrome p450 enzyme system.
The CYP4F3B isoform catalyzes the 20-hydroxylation of leukotriene B4.

Cytochrome P450 4F3 (CYP4F3) catalyzes the inactivation of leukotriene B(4) by omega-oxidation in human neutrophils. To understand the regulation of CYP4F3 expression, we analyzed the CYP4F3 gene and cloned a novel isoform (CYP4F3B) that is expressed in fetal and adult

The present study characterized in vitro metabolites of 20(R)-25-methoxyl-dammarane-3β, 12β, 20-triol (20(R)-25-OCH3-PPD) in mouse, rat, dog, monkey and human liver microsomes. 20(R)-25-OCH3-PPD was incubated with liver microsomes in the presence of NADPH. The reaction mixtures and the metabolites were identified
