We describe here a novel GPR119 agonist 24, which showed a potent and long-acting hypoglycemic effect in rats via oral dosing. For the discovery of 24, we chose compound 5, which possessed an oxadiazole linker, as a lead compound among our spirocyclic cyclohexane GPR119 agonist series, taking into account its lower plasma protein binding nature. 3,5-Difluoro and 4-methylsulfonylmethy groups on the
我们在这里描述了一种新型的GPR119激动剂24,它通过口服给药在大鼠中显示出强效且长效的降血糖作用。对于24的发现,考虑到其较低的血浆蛋白结合特性,我们在螺环式环己烷GPR119激动剂系列中选择了具有恶二唑接头的化合物5作为先导化合物。3,5-二氟和4- methylsulfonylmethy左侧苯基团,以及宝石二氟上的右侧组24分别对于其激动剂效力和代谢稳定性重要。
