摘要
东亚钳蝎(Buthus martensii Karsch,BmK)是治疗癫痫的经典中药之一,已有上千年的历史。从BmK毒液中分离纯化的神经毒素被认为是作用于膜离子通道的主要活性成分。电压门控钠通道(voltage-gated sodium channels,VGSCs)在癫痫发生中起着重要的作用,使其成为重要的癫痫药物靶点。BmK的长链毒素由60~70个氨基酸残基组成,能特异性识别VGSCs,其中用于建立癫痫模型的α-样神经毒素与VGSC受体位点3结合,可诱发鼠类癫痫。而β或β-样神经毒素则与VGSC受体位点4结合,对癫痫模型有显著的抗惊厥作用。本综述旨在阐明BmK多肽作用于VGSCs的抗惊厥或惊厥作用,同时也为抗癫痫药物设计提供潜在的框架。
The East Asian scorpion Buthus martensii Karsch(BmK)is one of the classical traditional Chinese medicines for treating epilepsy for over a thousand years.Neurotoxins purified from BmK venom are considered as the main active ingredients,acting on membrane ion channels.Voltage-gated sodium channels(VGSCs)play a crucial role in the occurrence of epilepsy,which make them become important drug targets for epilepsy.Long chain toxins of BmK,composed of 60–70 amino acid residues,could specifically recognize VGSCs.Among them,α-like neurotoxins,binding to the receptor site-3 of VGSC,induce epilepsy in rodents and can be used to establish seizure models.Theβorβ-like neurotoxins,binding to the receptor site-4 of VGSC,have significant anticonvulsant effects in epileptic models.This review aims to illuminate the anticonvulsant/convulsant effects of BmK polypeptides by acting on VGSCs,and provide potential frameworks for the anti-epileptic drug-design.
