  • 1. CYP1A2 is a highly polymorphic gene and CYP1A2 enzyme results in broad inter-individual variability in response to certain pharmacotherapies, while little is known about the genetic variation of CYP1A2 in Uyghur Chinese population. The aim of the present study was to screen Uyghur volunteers fo

  • 1. The aim of this study was to investigate the inhibitory effect of morusin on Glucuronosyltransferase (UGT) isoforms and cytochrome P450 enzymes (CYP450s). We also investigated the metabolism of morusin in human, rat, dog, monkey, and minipig liver microsomes. 2. 100 μM of morusin exhibited

  • RATIONALE: Menthofuran is a hepatotoxin and a major metabolite of pulegone, a monoterpene found in the essential oils of many mint species. It is bioactivated by cytochrome P450 (CYP) enzymes to reactive metabolites, which may further react with glutathione to form S-linked and N-linked conjugates.
