Several N-pyridin-3-yl spirobicyclic diamines, designed as conformationally restricted analogs of tebanicline (ABT-594), were synthesized as novel ligands for nicotinic acetylcholine receptors (nAChR). The spirocyclic compounds exhibited weaker binding affinity, than other constrained analogs in accord with a pharmacophore model. Nevertheless, some (1a, 1b) possessed (partial) agonist potencies comparable
合成了几种N-吡啶-3-基螺双环二胺,它们被设计为替班尼克的构象受限类似物(ABT-594),作为烟碱乙酰胆碱受体(nAChR)的新型配体。根据药效团模型,螺环化合物比其他约束类似物表现出更弱的结合亲和力。然而,在α4β2亚型中,一些(1a,1b)具有与尼古丁相当的(部分)激动剂效能,但相对于α3β4* nAChR具有极大的选择性。
