The synthesis and pharmacological characterization of a novel furan-based class of voltage-gated sodium channel blockers is reported. Compounds were evaluated for their ability to block the tetrodotoxin-resistant sodium channel Na(v)1.8 (PN3) as well as the Na(v)1.2 and Na(v)1.5 subtypes. Benchmark compounds from this series possessed enhanced potency, oral bioavailability, and robust efficacy in a
报道了一种新型的呋喃基电压门控钠通道阻滞剂的合成和药理学表征。评价了化合物阻断抗河豚毒素的钠通道Na(v)1.8(PN3)以及Na(v)1.2和Na(v)1.5亚型的能力。与临床使用的钠通道阻滞剂美西律和拉莫三嗪相比,该系列的基准化合物在神经性疼痛的啮齿动物模型中具有增强的效力,口服生物利用度和强大的功效,并具有改善的中枢神经系统和心血管安全性。
