Sodium channel blockers are important antiseizure drugs. Since the launch of phenobarbital in 1912, it has a development history of nearly 100 years. However, because of the confounding symptoms, complications, and complex intrinsic pathogenesis of epilepsy, the design and development of blockers specifically targeting sodium channels as antiseizure drugs are difficult and rarely reported. In this
钠通道阻滞剂是重要的抗癫痫药物。苯巴比妥自1912年问世以来,已有近100年的发展历史。然而,由于癫痫的混杂症状、并发症和复杂的内在发病机制,设计和开发专门针对钠通道作为抗癫痫药物的阻滞剂是困难的,并且很少报道。在这项研究中,我们设计并合成了一系列新型苯并[ d ]异恶唑衍生物作为抗惊厥药。其中,最有效的Z-6b对 MES 诱发的癫痫发作具有高保护作用,其 ED 50值为 20.5 mg/kg,高保护指数 (TD 50 /ED 50 ) 为 10.3。此外,Z-6b在膜片钳实验中显着抑制 Na V 1.1 通道,但几乎不抑制 Na V 1.2、Na V 1.3 和 Na V 1.6 通道。这些发现有力地支持了新的苯并[ d ]异恶唑衍生物通过选择性阻断电压门控钠通道 Na V 1.1 显示抗惊厥活性的假设,这为未来开发选择性 Na V 1.1 通道阻断剂作为抗癫痫药物提供了良好的替代方案。
