reported a series of isoflavone derivatives with antidyslipidemic activity. With this background, a series of isoflavone analogs of GW4064 were designed, synthesized and evaluated the lipid-lowering activity of analogs. As a result, most of compounds significantly reduced the lipid accumulation in 3T3-L1 adipocytes and four of them (10a, 11, 15c and 15d) showed stronger inhibitory than GW4064. The most
我们的小组先前已经报道了一系列具有抗血脂异常活性的异黄酮衍生物。在此背景下,设计,合成并评估了一系列GW4064的异黄酮类似物。其结果是,大多数化合物的显著降低脂质积聚在3T3-L1脂肪细胞和它们(四个10A,11,15C和15D)显示出比GW4064抑制更强。最有效的化合物15d在基于细胞的萤光素酶报告基因检测中表现出对FXR的有希望的激动活性。同时15d上调FXR,SHP和BSEP基因表达,下调脂肪生成基因SREBP-1c的mRNA表达。此外,与GW4064相比,在HepG2细胞毒性试验中还观察到了15d的改进安全性。分子对接研究进一步证实了获得的生物学结果,结果表明15d很好地适合FXR的结合口袋,并同时与一些关键残基相互作用。
