  The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of

  游离脂肪酸受体1（FFA1 / GPR40）作为治疗2型糖尿病的新靶标已引起人们的关注。相对较高的分子量和亲脂性阻碍了包括FAK1激动剂在内的数个系列的FFA1激动剂（由于对肝毒性的担忧而在III期研究中终止的最先进的化合物）。为了通过降低亲脂性来开发具有低肝毒性风险的有效FFA1激动剂，TAK-875的中间苯基被11个极性五元杂芳族化合物所取代。随后，对SAR的系统探索和分子建模的应用导致了化合物44的鉴定，它是一种出色的FFA1激动剂，在正常和2型糖尿病小鼠中均具有强大的降血糖作用，即使在两倍摩尔的TAK-875剂量下也具有低血糖风险和肝毒性。同时，指出了两个重要发现。首先，我们的噻唑系列中的甲基占据了一个小的疏水亚口袋，与TAK-875没有相互作用。此外，激动活性显示与噻唑核心和末端苯环之间的二面角具有良好的相关性。这些结果促进了对配体结合口袋的了解，并可能有助于设计更有希望的FFA1激动剂。
