aryl and acyl sulfonamides have been reported as potent inhibitors of NaV1.7, with high selectivity over the cardiac isoform NaV1.5. Herein, we report on the discovery of a novel series of N-([1,2,4]triazolo[4,3-a]pyridin-3-yl)methanesulfonamides as selective NaV1.7 inhibitors. Starting with the crystal structure of an acyl sulfonamide, we rationalized that cyclization to form a fused heterocycle would
钠通道Na V 1.7已经成为治疗疼痛的有前途的靶点,这是基于其在伤害感受中作用的强大遗传学验证。近年来,已经报道了许多芳基和酰基磺酰胺作为Na V 1.7的有效抑制剂,与心脏同工型Na V 1.5相比具有很高的选择性。在此,我们报道了一系列新的N -([1,2,4]三唑并[4,3 - a ]吡啶-3-基)甲磺酰胺作为选择性Na V的发现。1.7抑制剂。从酰基磺酰胺的晶体结构开始,我们合理地认为,形成稠合杂环的环化将改善物理化学性质,特别是亲脂性。我们的设计策略集中于优化Na V 1.7的效价和人体代谢稳定性。铅化合物10,13(GNE-131),和25显示出优异的效力,良好的体外代谢稳定性,和低体内在小鼠,大鼠,和狗的间隙。化合物13在诱导性疼痛的转基因小鼠模型中也显示出优异的功效。
