A series of tetrakis-azaaromatic quaternary ammonium salts was synthesized to identify compounds with higher affinity and selectivity as antagonists at neuronal nicotinic receptor subtypes (nAChR) that mediate nicotine-evoked DA release. A high hit rate was achieved in identifying potent analogs that inhibit these nAChRs. Three tetrakis analogs, 11j, 11f, and 11g, were identified as potent (IC(50)=3, 28 and 56nM, respectively) antagonists at these receptors. These compounds represent a novel structural class of nicotinic receptor antagonists.
合成了一系列四氮杂芳族季铵盐,以鉴定对介导尼古丁诱发多巴胺释放的神经元烟碱样受体亚型(nAChR)具有更高亲和力和选择性的拮抗剂化合物。在鉴定抑制这些nAChR的有效类似物方面取得了很高的命中率。三种四氮类似物11j、11f和11g被鉴定为这些受体的强效拮抗剂(IC(50)分别为3、28和56 nM)。这些化合物代表了一类新型的烟碱样受体拮抗剂结构。
