The preparation of novel pyridyl ethers as ligands for the nicotinic acetylcholine receptor (nAChR) is described. Variations of the ring size of the azacycle and substitution on the pyridine had dramatic effects on receptor binding affinity with IC50s at the alpha4beta2 nAChR ranging from 22 to >10,000 nM. The most potent molecule was (R)-2-chloro-3-(4-cyanophenyl)-5-((3-pyrrolidinyl)oxy)pyridine 27f
描述了新型吡啶基醚作为烟碱乙酰胆碱受体(nAChR)配体的制备。氮杂环的环大小的变化和吡啶上的取代对α4beta2nAChR处IC50的受体结合亲和力具有显着影响,范围为22至> 10,000 nM。最有效的分子是(R)-2-氯-3-(4-氰基苯基)-5-((3-吡咯烷基)氧基)吡啶27f,IC50为22 nM。
