CYP3A4 and CYP2D6 inhibitory activities of Indonesian medicinal plants.
Thirty samples of Indonesian medicinal plants were analyzed for their capacity to inhibit in vitro metabolism by human cytochrome P450 3A4 (CYP3A4) and CYP2D6 with a radiometric assay. The MeOH-soluble fractions of 25 samples, prepared from water extracts, demonstrated inhibitory activity more than 50% on the metabolism mediated by CYP3A4, and 21 samples on the metabolism mediated by CYP2D6. Am...
متن کاملExploration of catalytic properties of CYP2D6 and CYP3A4 through metabolic studies of levorphanol and levallorphan.
CYP2D6 and CYP3A4, two members of the cytochrome P450 superfamily of monooxygenases, mediate the biotransformation of a variety of xenobiotics. The two enzymes differ in substrate specificity and size and characteristics of the active site cavity. The aim of this study was to determine whether the catalytic properties of these isoforms, reflected by the differences observed from crystal structu...
متن کاملSesquiterpenes and flavonol glycosides from Zingiber aromaticum and their CYP3A4 and CYP2D6 inhibitory activities.
Three new sesquiterpenes, (2R,3S,5R)-2,3-epoxy-6,9-humuladien-5-ol-8-one (1), (2R,3R,5R)-2,3-epoxy-6,9-humuladien-5-ol-8-one (2), and (5R)-2,6,9-humulatrien-5-ol-8-one (3), and two new flavonol glycosides, kaempferol-3-O-(2,3-di-O-acetyl-alpha-l-rhamnopyranoside) (4) and kaempferol-3-O-(2,3,4-tri-O-acetyl-alpha-l-rhamnopyranoside) (5), were isolated from the EtOAc-soluble fraction of the water ...
متن کاملHemodialysis does not alter in vitro hepatic CYP3A4 and CYP2D6 metabolic activity in uremic serum
There is a paucity of studies evaluating the change in liver metabolism in subjects receiving hemodialysis. The purpose of this study was to compare the effect of uremic toxins on hepatic cytochrome P450 (CYP)3A4 and CYP2D6 metabolism before and after a 4-hour hemodialysis session. Midazolam and dextromethorphan were incubated with uremic serum collected from subjects before and after the 4-hou...
متن کاملMetabolic activation of benzodiazepines by CYP3A4.
Cytochrome P450 3A4 is the predominant isoform in liver, and it metabolizes more than 50% of the clinical drugs commonly used. However, CYP3A4 is also responsible for metabolic activation of drugs, leading to liver injury. Benzodiazepines are widely used as hypnotics and sedatives for anxiety, but some of them induce liver injury in humans. To clarify whether benzodiazepines are metabolically a...
