1-acyl-2-benzylpyrrolidines were discovered as potent and competitive dual orexin receptor antagonists. Metabolic stability was improved to afford oral exposure, and aqueous solubility was increased by twentyfold, providing compounds suitable for preclinical evaluation. Compound 27 showed insurmountable antagonism at both orexin 1 and orexin 2 receptor subtypes and displayed a comparable sleep-promoting
从在大鼠和人肝微粒体中具有高固有清除率和低水溶性的噻吩并哌啶前导化合物开始,发现了一系列新型的1-酰基-2-苄基吡咯烷酮,它们是有效且具有竞争力的双重orexin受体拮抗剂。改善了代谢稳定性以提供口服暴露,并且水溶性增加了二十倍,从而提供了适合临床前评估的化合物。化合物27对orexin 1和orexin 2受体亚型均显示出不可克服的拮抗作用,并且在大鼠中具有与Almorexant和suvorexant相当的促睡眠作用。
