Taking as models the polyamine toxin fraction FTX from the funnel-web spider venom, and the guanidinium moiety of guanethidine, a series of azaalkane-1, omega-diguanidinium salts were obtained. Some of them blocked ion fluxes through the neuronal nicotinic receptors for acetylcholine (nAChR). The blockade was exerted at submicromolar concentrations, suggesting a highly selective interaction with the
以来自漏斗网蜘蛛毒液的多胺毒素级分FTX和胍乙啶的胍基部分为模型,获得了一系列的氮杂烷-1,ω-双胍盐。其中一些阻滞了通过乙酰胆碱(nAChR)神经元烟碱受体的离子通量。阻断作用发生在亚微摩尔浓度,表明与nAChR具有高度选择性的相互作用。实际上,nAChR离子通道上的活性化合物无法识别牛肾上腺嗜铬细胞的电压依赖性Na +或Ca2 +通道。因此,这些化合物可能是阐明nAChR受体在中枢神经系统和外周神经系统中的功能的有用工具。
