The effects of opioids in the central nervous system (CNS) provide significant benefit in the treatment of pain but can also lead to physical dependence and addiction, which has contributed to a growing opioid epidemic in the United States. Gastrointestinal dysfunction is an additional serious consequence of opioid use, and this can be treated with a localized drug distribution of a non-CNS penetrant, peripherally restricted opioid receptor antagonist. Herein, we describe the application of Theravance's multivalent approach to drug discovery coupled with a physicochemical property design strategy by which the N-substituted-endo-3-(8-aza-bicyclo[3.2.1]oct-3-yl)-phenyl carboxamide series of μ-opioid receptor antagonists was optimized to afford the orally absorbed, non-CNS penetrant, Phase 3 ready clinical compound axelopran (TD-1211) 19i as a potential treatment for opioid-induced constipation.

Axelopran(TD-1211)的发现:外围受限制的μ阿片受体拮抗剂。

阿片类药物在中枢神经系统(CNS)中的作用在治疗疼痛方面提供了显着的益处,但也可能导致身体上的依赖性和成瘾性,这在美国加剧了阿片类药物的流行。胃肠功能障碍是使用阿片类药物的另一个严重后果,可以通过非CNS渗透剂,外周限制性阿片受体拮抗剂的局部药物分布来治疗。在这里,我们描述了Theravance的多价方法在药物发现中的应用以及理化性质设计策略,该策略通过N-取代的-endo-3-(8-氮杂-双环[3.2.1] oct-3-yl)-苯基对羧酰胺系列的μ阿片受体拮抗剂进行了优化,以提供口服吸收的非CNS渗透剂,
