A novel series of GPR40 agonists is designed by introducing nitrogen-containing heterocyclic ring at the terminal phenyl ring of TAK-875 with the aim of decreasing its lipophilicity. Three different β-substituted phenylpropionic acids were investigated as the acidic components. A total of 34 compounds have been synthesized, among which, compound 30 exhibited comparable GPR40 agonistic activity in vitro
通过在TAK-875的末端苯环上引入含氮杂环,以降低其亲脂性,设计了一系列新的GPR40激动剂。研究了三种不同的β-取代苯基丙酸作为酸性组分。总共合成了34种化合物,其中化合物30在体外具有与TAK-875相当的GPR40激动活性,并且通过计算得出相对较低的亲脂性(30,EC 50 = 1.2μM,cLogP = 1.3; TAK-875:EC 50 = 5.1μM,cLogP = 3.4)。此外,化合物30能增强从正常ICR小鼠中分离的原胰岛的胰岛素分泌,并在体外对细胞色素P450没有明显的抑制作用。在体内,化合物30在正常ICR小鼠的口服葡萄糖耐量试验(oGTT)中显示出功效。
