Abstract

A series of tertiary amine analogs derived from lead azaaromatic quaternary ammonium salts has been designed and synthesized. The preliminary structure-activity relationships of these new analogs suggest that such tertiary amine analogs, which potently inhibit nicotine-evoked dopamine release from rat striatum, represent drug-like inhibitors of α6-containing nicotinic acetylcholine receptors. The bis-tertiary amine analog 7 exhibited an IC(50) of 0.95 nM, while the tris-tertiary amine analog 19 had an IC(50) of 0.35 nM at nAChRs mediating nicotine-evoked dopamine release.

摘要

设计并合成了一系列衍生自先导氮杂芳基季铵盐的三级胺类似物。这些新类似物的初步结构-活性关系表明，这些强效抑制大鼠纹状体烟碱诱发多巴胺释放的三级胺类似物，是含有α6 的烟碱型乙酰胆碱受体的类药性抑制剂。双三级胺类似物 7 的 IC50 为 0.95 nM，而三三级胺类似物 19 在介导烟碱诱发多巴胺释放的 nAChRs 上的 IC50 为 0.35 nM。
