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。

genetic evidence has identified the voltage-gated sodium channel NaV1.7 as an attractive target for the treatment of pain. We initially identified naphthalene sulfonamide 3 as a potent and selective inhibitor of NaV1.7. Optimization to reduce biliary clearance by balancing hydrophilicity and hydrophobicity (Log D) while maintaining NaV1.7 potency led to the identification of quinazoline 16 (AM-2099).
人类遗传证据已将电压门控钠通道Na V 1.7确定为治疗疼痛的引人注目的靶标。我们最初确定萘磺酰胺3是Na V 1.7的有效和选择性抑制剂。通过在保持Na V 1.7效力的同时平衡亲水性和疏水性(Log D)来降低胆汁清除率的优化导致了对喹唑啉16(AM-2099)的鉴定。化合物16在大鼠和狗中显示出良好的药代动力学特征,并在口服给药后在小鼠行为模型中证明了组胺诱导的scratch痒的剂量依赖性降低。
