therapeutic potential for the treatment of diabetes, but few selective agonists have been reported. We identified an indazole-6-phenylcyclopropylcarboxylic acid series of GPR120 agonists and conducted SAR studies to optimize GPR120 potency. Furthermore, we identified a (S,S)-cyclopropylcarboxylic acid structural motif which gave selectivity against GPR40. Good oral exposure was obtained with some compounds
GPR120激动剂具有治疗糖尿病的潜力,但很少有选择性激动剂的报道。我们确定了GPR120激动剂的吲唑-6-苯基环丙基羧酸系列,并进行了SAR研究,以优化GPR120的效力。此外,我们确定了(S,S)-环丙基羧酸结构基序,该结构基序对GPR40具有选择性。一些化合物显示出意外的高CNS渗透性,获得了良好的口服暴露。增加的MDCK外排用于鉴定化合物,例如33具有较低的中枢神经系统渗透性,并且在口服葡萄糖耐量研究中具有活性。在GPR120 null和野生型小鼠中观察到差异活性,表明该作用是通过涉及GPR120激动的机制起作用的。
