Using structure- and ligand-based design principles, a novel series of piperidyl chromane arylsulfonamide Nav1.7 inhibitors was discovered. Early optimization focused on improvement of potency through refinement of the low energy ligand conformation and mitigation of high in vivo clearance. An in vitro hepatotoxicity hazard was identified and resolved through optimization of lipophilicity and lipophilic
使用基于结构和配体的设计原理,发现了一系列新的哌啶基苯并吡喃基苯并二氢呋喃基氨基磺酰胺Nav1.7抑制剂。早期优化的重点是通过优化低能配体构象和减轻体内清除率来提高效能。通过优化亲脂性和亲脂性配体效率,确定并解决了体外肝毒性危害,从而达到GNE-616(24),这是一种高效,代谢稳定的Nav1.7亚型选择性抑制剂。化合物24在依赖Nav1.7的小鼠模型中显示出强大的PK / PD反应,并且使用定点诱变来鉴定对24的同工型选择性谱至关重要的残基。
