The free fatty acid receptor 1 (FFA1/GPR40) has attracted extensive attention as a novel antidiabetic target. Aiming to explore the chemical space of FFA1 agonists, a new series of lead compounds with amide linker were designed and synthesized by combining the scaffolds of NIH screened lead compound 1 and GW9508. Among them, the optimal lead compound 17 exhibited a considerable agonistic activity (45
游离
脂肪酸受体1(FFA1 / GPR40)作为新型的抗糖尿病靶标已引起广泛关注。为了探索FFA1激动剂的
化学空间,通过结合NIH筛选的
铅化合物1和GW9508的支架,设计并合成了一系列新的具有酰胺连接基的
铅化合物。其中,最佳的先导化合物17与NIH筛选的化合物1(15.32%)相比,显示出显着的激动活性(45.78%)。在正常小鼠的OG
TT期间,化合物17在50mg / kg的剂量下显示出显着的降糖作用(-23.7%),接近
二甲双胍(200mg / kg)的降血糖作用(-27.8%)。另外,化合物17(100mg / kg)在2型糖尿病小鼠中还表现出
葡萄糖耐量的显着改善,其中
葡萄糖AUC0-2h减少了29.1%。
