been investigated. Several N-(3-pyridinyl) derivatives of bridged bicyclic diamines exhibit double-digit-picomolar binding affinities for the alpha 4 beta 2 subtype, placing them with epibatidine among the most potent nAChR ligands described to date. Structure-activity studies have revealed that substitutions, particularly hydrophilic groups in the pyridine 5-position, differentially modulate the agonist
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,
