  N-（3-吡啶基）-桥联的双环二胺的结构活性研究和镇痛效果，对烟碱乙酰胆碱受体的异常激动剂。

  摘要：

  已经研究了一系列针对神经元烟碱乙酰胆碱受体（nAChRs）的激动剂。桥接的双环二胺的几种N-（3-吡啶基）衍生物对α4β2亚型表现出两位数皮摩尔的结合亲和力，使它们与Epibatidine成为迄今为止描述的最有效的nAChR配体之一。结构活性研究表明，取代基（尤其是吡啶5位上的亲水基团）在神经节和中心nAChR亚型上差异调节激动剂活性，因此可以在体外证明改进的亚型选择性。在广泛的疼痛状态（包括急性热伤害感受，持续性疼痛和神经性异常性疼痛的啮齿动物模型）中已经实现了镇痛效果。很遗憾，
