most significantly agonistic activity against farnesoid X receptor (FXR) with an EC50 value of 7.18 μM, and its agonistic effect was verified through the investigation of FXR downstream target genes including small heterodimer partner 1 (SHP1), bile salt export pump (BSEP), and organic solute transporter subunit alpha and beta (OSTα and OSTβ). The potential interaction of compound 6 with FXR was analyzed
对巴戟天的研究导致分离出十二种化合物(1-12),包括三种新的鸢尾花苷morindalins A-C(1-3)和九种已知化合物(4-12)。使用HRMS,1D和2D NMR,电子圆二色性(ECD)光谱以及量子化学计算进行了结构鉴定。化合物6以EC 50对法呢类X受体(FXR)表现出最显着的激动活性FXR的目标值为7.18μM,并通过研究FXR下游靶基因(包括小异二聚体伴侣1(SHP1),胆汁盐输出泵(BSEP)以及有机溶质转运子亚基α和β(OSTα和OSTβ))证实了其激动作用。通过分子对接和分子动力学刺激分析了化合物6与FXR的潜在相互作用,发现氨基酸残基Leu287,Thr288和Ser332在化合物6向FXR的激活中起关键作用。这些发现表明化合物6可以被认为是FXR激动剂发展的潜在候选者。
