  芋螺毒素(conotoxin,conopeptide,CTX)是热带海洋软体动物芋螺分泌的一类用于麻醉猎物的神经毒素肽,是当今国际生物药物研究的热点,被誉为海洋药物宝库,已跃居动物神经毒素研究的首位。其结构新颖,多样性高,活性强,选择性高,能区分各种离子通道的不同亚型,广泛应用于神经药理学的研究、及作为诊断试剂与治疗药物。不同芋螺种类的毒素互不相同,且同一种类不同个体之间的毒素成份及其活性也差异很大,特别是对神经系统疾病有非常重要的研究与诊断治疗作用。在我国,芋螺是海南特有的药用海洋生物资源,其毒素具有特异结合动物体内各种离子通道受体的特殊功能,在镇痛和戒烟戒毒,以及治疗帕金森症、精神病等重大疾病方面具有极好的应用前景。
