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。
