3-aryl-indazole derivatives were identified as potent and selective Nav1.7 inhibitors. Compound 29 was shown to be efficacious in the mouse formalin assay and also reduced complete Freund’s adjuvant (CFA)-induced thermal hyperalgesia and chronic constriction injury (CCI) induced cold allodynia and models of inflammatory and neuropathic pain, respectively, following intraperitoneal (IP) doses of 30 mg/kg
3-芳基吲哚和3-芳基吲唑衍生物被确定为有效的和选择性的Na v 1.7抑制剂。化合物29在小鼠福尔马林测定中显示有效,并且在腹膜内(IP)后分别降低了完全弗氏佐剂(CFA)引起的热痛觉过敏和慢性收缩损伤(CCI)引起的冷痛觉过敏以及炎性和神经性疼痛模型剂量为30 mg / kg。观察到的功效可能与小鼠背根神经节暴露和Na V 1.7效价与29相关。
