Starting from a known non-specific agonist (1) of nicotinic acetylcholine receptors (nAChRs), rationally guided structural-based design resulted in the discovery of a small series of 5′-phenyl-1,2,5,6-tetrahydro-3,3′-bipyridines (3a–3e) incorporating a phenyl ring off the pyridine core of 1. The compounds were synthesized via successive Suzuki couplings on a suitably functionalized pyridine starting
从已知的烟碱乙酰胆碱受体(nAChRs)的非特异性激动剂(1)开始,合理指导的基于结构的设计导致发现了一系列小分子5'-苯基-1,2,5,6-tetrahydro-3 ,3'-联吡啶(3a - 3e)在1的吡啶核上掺入苯环。通过在适当官能化的吡啶起始单体4上的连续Suzuki偶合来合成化合物,以分别在3-和5-位上附加苯基和吡啶基取代基,然后在侧翼的吡啶基环上进行随后的修饰以提供目标化合物。化合物3a是一种新型拮抗剂,对α3β4nAChR(K i = 123 nM)的选择性比α4β2和α7受体高。
