secretion by Takeda G-protein-coupled receptor 5 (TGR5) agonists might be a superior alternative for the treatment of type 2 diabetes mellitus. A series of 4-phenoxythiazol-5-carboxamides were developed as highly potent TGR5 agonists using a bioisosteric replacement strategy based on the scaffold of 4-phenoxynicotinamides. The structure-activity relationship on the bottom phenyl ring and the thiazole ring
一种由武田G蛋白偶联受体5(TGR5)激动剂刺激内源性胰高血糖素样肽1(GLP-1)分泌的新疗法可能是治疗2型糖尿病的更好选择。一系列的4-苯氧基噻唑-5-羧酰胺被开发为高效的TGR5激动剂,使用了基于4-苯氧基烟酰胺骨架的生物等位取代策略。广泛研究了底部苯环和噻唑环上的结构-活性关系,并且2-甲基-噻唑衍生物30c和30e在体外对人TGR5表现出最佳的效价,EC50值约为1 nM。虽然具有出色的体外效能,但2-甲基噻唑在高微粒体清除率方面存在缺陷。
