isoform-selective inhibitors of the human sodium channel hNaV1.7. The optimization of these inhibitors is described. We aimed to improve potency against hNaV1.7 while minimizing off-target safety concerns and generated compound 3. This agent displayed significant analgesic effects in rodent models of acute and inflammatory pain and demonstrated that binding to the voltage sensor domain 4 site of NaV1.7 leads to
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。
