  • 生物活性

    Guggulsterone, a plant sterol that lowers serum cholesterol, has been shown to antagonize FXR activated genes. Transient transfection assay of a human BSEP/luciferase reporter in HepG2 cells transfected with FXR reveals that guggulsterone strongly antagonizes bile acid induction of the BSEP gene. On the other hand, guggulsterone has no effect on FXR inhibition of the CYP7A1 gene, but strongly inhibits the human CYP7A1 gene by activation of pregnane X receptor (PXR).

  • 不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

    动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 AKm系数


    例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
