  • 生物活性


    Obeticholic Acid (6alpha-ethyl-chenodeoxycholic acid, 6-ECDCA, INT-747) 是一种有效的和选择性的FXR激动剂,EC50值为99 nM[1]。

    法尼醇X 受体(farnesoid X receptor,FXR)是一个核受体,参与胆汁酸的动态平衡,肝纤维化,肝脏和肠道炎症以及心血管疾病[2]。

    Obeticholic Acid是一种有效的和选择性的FXR激动剂,具有抗胆汁淤积活性[1]。Obeticholic Acid是半合成胆汁酸衍生物和有效的FXR配体。在雌激素诱导的胆汁淤积大鼠中,6-ECDCA防止17α-乙炔雌二醇(E217α)诱导的胆汁淤积[2]。在肝硬化门脉高压(PHT)大鼠模型中,INT-747 (30 mg/kg)重新激活FXR下游的信号通路,通过降低肝内总血管阻力(IHVR)从而降低门静脉压力,不会产生有害的全身性低血压。这种效应与增加的eNOS活性相关联[3]。在盐敏感高血压和胰岛素抗性(IR)Dahl大鼠模型中,高盐(HS)饮食显著增加全身血压和下调组织DDAH的表达。INT-747增强胰岛素的敏感性,抑制DDAH表达的下降[4]。

  • 动物实验

    生理盐水使用 PE-50 聚乙烯管在右颈动脉进行注射

  • 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。
