电压门控钠通道 (VGSC) 在可兴奋神经元和其他细胞中动作电位的产生和传播中发挥着核心作用,是常用局部麻醉药、抗心律失常药和抗惊厥药的靶点。它们也是神经毒素(包括贝类毒素)的常见目标。贝类毒素是海洋和淡水系统中原核蓝藻和真核甲藻产生的多种有毒次级代谢产物,可通过食物链在海洋动物体内积累。食用受贝类毒素污染的海鲜可能会导致人类贝类中毒,可能致命。本文概述了作用于 VGSC 的贝类毒素的结构、生物活性和药理学,并简要讨论了其治疗疼痛的药物潜力。
Voltage-gated sodium channels (VGSCs) play a central role in the generation and propagation of action potentials in excitable neurons and other cells and are targeted by commonly used local anesthetics, antiarrhythmics, and anticonvulsants. They are also common targets of neurotoxins including shellfish toxins. Shellfish toxins are a variety of toxic secondary metabolites produced by prokaryotic cyanobacteria and eukaryotic dinoflagellates in both marine and fresh water systems, which can accumulate in marine animals via the food chain. Consumption of shellfish toxin-contaminated seafood may result in potentially fatal human shellfish poisoning. This article provides an overview of the structure, bioactivity, and pharmacology of shellfish toxins that act on VGSCs, along with a brief discussion on their pharmaceutical potential for pain management.
