isoxazolylpyridine ether scaffolds to be versatile building blocks for creating potent α4β2 nicotinic acetylcholine receptor (nAChR) partial agonists with excellent selectivity over the α3β4 subtype. In our continued efforts to develop therapeutic nicotinic ligands, seven novel hybrid compounds were rationally designed, synthesized, and evaluated in [3H]epibatidine binding competition studies.

我们先前曾报道过环丙基吡啶和异恶唑基吡啶醚支架是通用的构建基块,可用于创建有效的α4β2烟碱型乙酰胆碱受体(nAChR)部分激动剂,其选择性优于α3β4亚型。在我们不断努力开发治疗性烟碱配体的过程中,合理设计,合成和评估了[ 3 H] epibatidine结合竞争研究中的7种新型杂化化合物。将含环丙烷或异恶唑的侧链并入1-(吡啶-3-基)-1,4-二氮杂苯或2-(吡啶-3-基)-2,5-二氮杂双环[2.2]的5位上.1]庚烷导致K i高度有效和选择性的α4β2* nAChR部分激动剂α4β2的值为0.5-51.4 nM,α3β4和α7的亲和力可忽略不计。此外,化合物21,25和30保持的功能简(EC 50和IC 50个的父含氮杂环丁烷化合物的15-50纳米的值)3和4在86 RB +离子通量测定法。体内最有前途的化合物的功效21证实在小鼠SmartCube ®平台和古典强迫游泳测试中,支
