optimization of orexin 2 receptor (OX2R) antagonistic activity, stability in liver microsomes, time dependent CYP3A4 inhibition, and aqueous solubility. Compounds were assessed for their brain-penetrating potential in in vivo experiments to select the most promising compounds for our in vivo sleep model. Our lead optimization efforts led to the discovery of the potent, brain penetrating and orally active,
选择性食欲素 2 受体拮抗剂 (2-SORA),如 seltorexant (15),正在临床开发中,用于治疗失眠和其他疾病,如抑郁症。在此,我们报告了我们的结构-活性-关系 (SAR) 优化工作,从 HTS 命中 (1) (N-(1-((5-乙酰呋喃-2-基)甲基)-1H-吡唑-4-基)-5-(间甲苯基)噁唑-4-甲酰胺)开始,该化合物源自一个不相关的内部 GPCR-激动剂程序。药物化学工作侧重于优化食欲素 2 受体 (OX2R) 拮抗活性、肝微粒体的稳定性、时间依赖性 CYP3A4 抑制和水溶性。在体内实验中评估了化合物的大脑穿透潜力,以便为我们的体内睡眠模型选择最有前途的化合物。我们的先导优化工作导致发现了有效的、可穿透大脑且具有口服活性的 2-SORA(N-(1-(2-(5-甲氧基-1H-吡咯并[3,2-b]吡啶-3-基)乙基)-1H-吡唑-4-基)-5-(间甲苯基)噁唑-4-甲酰胺)43,在大鼠睡眠模型中的疗效与
