电压门控钠通道Na V 1.7是经遗传验证的疼痛靶标。鉴定具有所有所需特性的Na V 1.7抑制剂以开发为口服疼痛治疗剂一直是一项重大挑战。在这里,我们报告进行系统的结构-活性关系(SAR)研究,以鉴定新型磺酰胺衍生物作为强效,选择性和状态依赖性Na V 1.7疼痛抑制剂。从苯并恶嗪跃迁至苯并二氢吡喃和茚满双环体系,然后在磺酰胺上用噻唑置换,导致铅分子的溶解度,对Na V 1.5的选择性和对CYP2C9的抑制均得到显着改善。引线分子13,29,32,43,和51显示出在不同的物种和藜芦健壮功效和在小鼠福尔马林诱导的炎性疼痛模型的有利的药代动力学(PK)曲线。化合物51还显示出对CCI诱导的神经性疼痛模型的显着影响。51的图谱表明它有潜力进一步评估其作为疼痛的治疗剂。
