    • The present invention provides compounds, pharmaceutical compositions and methods that are useful in modulating the farnesoid X receptor (FXR). As FXR is involved in negatively controlling the expression level of cholesterol 7 alpha -hydroxylase (cyp7a), the rate-limiting enzyme involved in the oxidative metabolism of cholesterol into bile acids, the compounds described herein find utility in treating diseases associated with abnormally high or low cholesterol levels. In certain aspects, the FXR modulators (e.g., antagonists) described herein block the negative feed-back downregulation of cyp7a expression produced by certain cholic acids, the endogenous ligands for FXR. Moreover, as FXR forms heterodimers with the retinoid X receptor (RXR) in some cell types, modulation of the level of FXR activity in cells has a wide range of effects on a variety of biological processes which are mediated by RXR or other RXR-interacting proteins such as PPAR gamma and PPAR alpha . Thus, compounds described herein are useful in treating other biological activities such as obesity, diabetes, lipid associated disorders, cancer, inflammatory disorders, disorders involving a disrupted or dysfunctional epidermal barrier, and various other metabolic disorders.
    • 本发明提供了可用于调节法呢酯X受体(FXR)的化合物,药物组合物和方法。 由于FXR涉及负调控胆固醇7α-羟化酶(cyp7a)的表达水平,涉及胆固醇胆固醇氧化代谢的限速酶,本文所述的化合物可用于治疗与异常高相关的疾病或 低胆固醇水平 在某些方面,本文所述的FXR调节剂(例如拮抗剂)阻断某些胆酸(FXR的内源性配体)产生的cyp7a表达的负反馈下调。 此外,由于FXR在一些细胞类型中与类视黄醇X受体(RXR)形成异源二聚体,因此细胞中FXR活性水平的调节对由RXR或其他RXR相互作用介导的各种生物过程具有广泛的影响 蛋白质如PPARγ和PPARα。 因此,本文所述的化合物可用于治疗其它生物活性,例如肥胖症,糖尿病,脂质相关疾病,癌症,炎性疾病,涉及破坏性或功能失调的表皮屏障的疾病以及各种其它代谢紊乱。
