  genetic validation, NaV1.7 has attracted significant interest as a target for the treatment of pain. We have previously reported on a number of structurally distinct bicyclic heteroarylsulfonamides as NaV1.7 inhibitors that demonstrate high levels of selectivity over other NaV isoforms. Herein, we report the discovery and optimization of a series of atropisomeric quinolinone sulfonamide inhibitors [Bicyclic

  由于其强大的遗传学验证，Na V 1.7作为治疗疼痛的靶标引起了人们的极大兴趣。我们以前曾报道过许多结构上不同的双环杂芳基磺酰胺盐，它们是Na V 1.7抑制剂，与其他Na V同工型相比，具有较高的选择性。在此，我们报告了一系列阻转异构的喹啉酮磺酰胺抑制剂[双环磺酰胺化合物作为钠通道抑制剂]的发现和优化及其制备方法。WO 2014201206， 2014]的Na V 1.7，这表明的Na纳摩尔抑制V 1.7和比其他钠通道亚型表现出高水平的选择性。在优化了包括PXR活化，CYP2C9抑制和CYP3A4 TDI在内的代谢和药代动力学特性后，将几种化合物推入了体内靶标参与和功效模型。在小鼠中进行测试时，化合物39（AM-0466）在组胺诱导的瘙痒性Na V 1.7依赖性模型（瘙痒）中以及在辣椒素诱导的痛觉伤害模型中均表现出强大的药效学活性，而在开腹中没有任何混淆作用现场活动。
