BergaptolA hydroxylated psoralen that acts as a potent inhibitors of debenzylation activity of CYP3A4 enzyme with an IC50 value of 24.92 uM. Recent studies suggest that it may have antiproliferative and anticancer properties.target: CYP3A4 [1]IC50: 24.92 [1]For in vivo enzyme activity analysis, 100 μM bergaptol was added to the cultures for an additional 24 h at 37°C. After centrifugation, the supernatant was used to measure the bergapten yield by high performance liquid chromatography (HPLC).[2]
