Polyamine toxins from orb weaver spiders are attractive pharmacological tools particularly for studies of ionotropic glutamate (iGlu) receptors in the brain. These polyamine toxins are biosynthesized in a combinatorial manner, providing a plethora of related, but structurally complex toxins to be exploited in biological studies. Here, we have used solid-phase synthetic methodology for the efficient
来自天体织布工蜘蛛的多胺毒素是有吸引力的药理工具,尤其是用于研究大脑中离子型谷氨酸(iGlu)受体的药物。这些多胺毒素以组合方式生物合成,提供了大量相关但结构复杂的毒素,可用于生物学研究。在这里,我们已使用固相合成方法从Nephila clavata有效合成Joro蜘蛛毒素4(JSTX-4)(1),为使用电生理学对iGlu受体亚型进行生物学评估提供了足够量的毒素。生物学评估表明,JSTX-4仅在高μM浓度下抑制iGlu受体,因此其效力远低于结构相关的多胺毒素。
