sulfonamides as potent Nav1.7 inhibitors with excellent selectivity against the Nav1.5 isoform, which is expressed in the heart muscle. Elaboration of initial lead compound 3d afforded exemplar 13, which featured attractive physicochemical properties, outstanding lipophilic ligand efficiency and pharmacological selectivity against Nav1.5 exceeding 1000-fold. Key structure-activity relationships associated
对人类遗传学的研究表明,Nav1.7电压门控钠通道的抑制剂作为治疗慢性疼痛综合症的疗法具有广阔的前景。在本文中,我们报道了新型的,周边受限制的苯并恶唑啉酮芳基磺酰胺类药物,作为有效的Nav1.7抑制剂,对Nav1.5亚型具有很好的选择性,后者在心肌中表达。最初的铅化合物3d的精制提供了示例13,其特征在于诱人的理化性质,出色的亲脂性配体效率和针对Nav1.5的药理选择性超过1000倍。与口服生物利用度相关的关键结构-活性关系被用于发现化合物17
