Garlic and Natto K2 were classified as non-inhibitors. Although Agaricus, noni juice, mistletoe and green tea inhibited CYP3A4 metabolism in vitro, clinically relevant systemic or intestinal interactions with CYP3A4 were considered unlikely, except for a probable inhibition of intestinal CYP3A4 by the green tea product.Note : Testosterone was used as a substrate and ketoconazole as a positive quantitative inhibition control.
Part Used : -Activity : CYP3A4 INHIBITIONSolvent/Active Compound : KaempferolType of experiment : in vitroType of animal : -Type of study : -N(Total) : -N(Treatment) : -Sex : -Age : -Route : -Dose/Conc.(herb) : -Duration : -Type of interaction : PharmacokineticsInteraction with drug : -Dose/Conc.(drug) : -Result : PositiveRemark :Note : Three coumarins and 12 flavonoids significantly suppressed CYP3A4 or CYP2C9 activities. 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.
