protein-coupled receptor 119 (GPR119) agonist. To occupy a presumed hydrophobic space between the pyrimidine and piperidine rings in interaction with GPR119, we replaced the linker oxygen with nitrogen. Subsequently, the introduction of a substituent at the bridging nitrogen atom was explored. We found that the installation of N-trifluoromethyl group 10 not only enhanced GPR119 agonist activity but also considerably
我们进行了涉及 propan-2-yl 4-(6-[5-(methanesulfonyl)-2,3-dihydro-1 H -indol-1-yl]pyrimidin-4-yl}oxy)piperidine-1 的优化工作-羧酸盐1,我们之前发现它是一种新型 G 蛋白偶联受体 119 (GPR119) 激动剂。为了在与 GPR119 相互作用的嘧啶和哌啶环之间占据一个假定的疏水空间,我们用氮替换了接头氧。随后,探索了在桥连氮原子上引入取代基。我们发现安装了N-三氟甲基10不仅增强了 GPR119 激动剂的活性,而且显着改善了人类 ether-à-go-go 相关基因 (hERG) 的抑制特性。对于非氟化取代基,例如乙基类似物8b,未观察到这些改进。下一个优化工作的重点是探索二氢吲哚环的新替代结构和哌啶N- Boc 基团的等排置换,以提高溶解度、代谢稳定性和口服生物利用度。结果,N -1
