(Thummel et al., 1996). It is estimated that up to 50% of all drugs are metabolized by CYP3A4 and that substrate drugs can be found in almost all therapeutic drug classes (Wilkinson, 2005). Variation in CYP3A4 activity is unimodal (Wilkinson, 2005) and despite a significant ...
Synthetic cannabinoid designer drugs have emerged as drugs of abuse during the last decade, and acute intoxication cases are documented in the scientific literature. Synthetic cannabinoids are extensively metabolized, but our knowledge of the involved enzymes is limited. Here, we investigated the metaboli...
John's wort can activate CYP3A4, causing a decrease in the activity of many drugs. Quercetin, echinacea, and ginseng may have similar effects. To see a list of medications that are metabolized by CYP3A4, sign in >> Join today to unlock all member benefits including full access to all ...
【摘要】Objective To investigate the in vitro inhibition of kudiezi injection (KDZi) on liver microsomal CYP3A4 in rats and the potential herb-drug interaction with drugs metabolized by CYP3A4 enzyme in clinical ap-plication. Methods The test groups included a negative control group, an inhibito...

These compounds are predominantly metabolized by CYP3A4, unaffected by p-glycoprotein and have abundant clinical studies which can be used for validation purposes. Simulated apparent clearance, obtained by use of the Simcyp Population-based Simulator and in vitro in vivo extrapolation (IVIVE) ...
where it catalyzes oxidation of an extraordinarily wide variety of structurally distinct ligands. More than half of all small molecule drugs commonly used by humans are metabolized by CYP3A4. BioVision’s EZCypTM 3A4 is a permeabilized and stabilized dried yeast powder preparation containing recombin...
