The synthesis, SAR and preclinical characterization of a series of 6-chloro-N-(2-(4,4-difluoropiperidin-1-yl)-2-(2-(trifluoromethyl)pyrimidin-5-yl)ethyl)quinoline-5-carboxamide based P2X7 antagonists is described herein. The lead compounds are potent inhibitors in Ca(2+) flux and whole blood IL-1β P2X7 release assays at both human and mouse isoforms. Compound 1e showed a robust reduction of IL-1β release
一系列6-氯-N-(2-(4,4-二氟哌啶-1-基)-2-(2-(三氟甲基)嘧啶-5-基)乙基)喹啉-的合成,SAR和临床前表征本文描述了基于5-羧酰胺的P2X7拮抗剂。铅化合物是Ca(2+)通量和全血IL-1βP2X7人体和小鼠同种型释放试验的有效抑制剂。化合物1e在口服剂量为50mg / kg的小鼠离体模型中显示出IL-1β释放的强烈降低。在小鼠SNI触觉性异常性疼痛,角叉菜胶诱发的爪水肿或CIA模型中评估化合物1e不会产生镇痛或抗炎作用。
