Lineweaver-Burk plot analysis indicated that apigenin and its dimer amentoflavone and imperatorin displayed a mixed type of inhibition on CYP3A4 or CYP2C9. Among the inhibitors, amentoflavone was the most potent inhibitor of CYP3A4 and CYP2C9 activities with IC50 values of 0.07 and 0.03 micromolar, respectively. The Ki value of amentoflavone was significantly lower than that of the CYP2C9 inhibition positive control sulfaphenazole.
