英文摘要
A dietary methoxyflavonoid, chrysoeriol, inhibited DNA damage induced by the carcinogenic endogenous estrogen metabolite, 4-OHE2.In a molecular docking analysis, chrysoeriol was found to fit well into the active site of CYP1B1, but not into the active site of CYP1A2 and 1A1 because of steric collisions between the methoxy substituent of this methoxyflavonoid. This indicates that such methoxyflavonoids may be a chemopreventive modulator involved in carcinogenesis such as in breast cancer.
