我们报告了一系列新型的芳基磺酰胺类化合物,它们可作为人类钠通道hNa V 1.7的纳摩尔强效,亚型选择性抑制剂。描述了这些抑制剂的优化。我们旨在提高针对hNa V 1.7的效力,同时将脱靶安全隐患降至最低,并生成化合物3。该剂在急性和炎性疼痛的啮齿动物模型中表现出显着的镇痛作用,并证明与Na V 1.7的电压传感器结构域4的结合导致体内的镇痛作用。我们的发现证实了hNa V 1.7作为治疗疼痛的药物靶标的重要性。

In this article, we describe the discovery of an aryl etherseries of potent and selective Nav1.3 inhibitors. Based on structural analogy to a similar series of compounds we have previously shown bind to the domain IV voltage sensor region of Nav channels, we propose this series binds in the same location. We describe the development of this series from a published starting point, highlighting key selectivity
在本文中,我们描述了一种有效的和选择性的Na v 1.3抑制剂的芳基醚系列的发现。基于与先前显示的类似系列化合物的结构相似性,我们结合至Na v通道的IV域电压传感器区域,我们建议该系列结合在同一位置。我们从已公开的出发点描述该系列的开发,重点介绍关键的选择性和效能数据,以及旨在验证Na v 1.3作为疼痛目标的多项研究。
