A 3-pyridyl ether scaffold bearing a cyclopropane-containing side chain was recently identified in our efforts to create novel antidepressants that act as partial agonists at α4β2-nicotinic acetylcholine receptors. In this study, a systematic structure–activity relationship investigation was carried out on both the azetidine moiety present in compound 3 and its right-hand side chain, thereby discovering
最近在我们努力创造新型抗抑郁药时发现了一种带有含环丙烷侧链的 3-吡啶基醚支架,这些抗抑郁药可作为 α4β2-烟碱型乙酰胆碱受体的部分激动剂。在这项研究中,对化合物3 中的氮杂环丁烷部分及其右侧链进行了系统的构效关系研究,从而发现了多种保留生物活性并具有改善的化学稳定性的新型烟碱配体。与母体化合物4和N-甲基吡咯烷类似物相比,最有希望的化合物24、26和30表现出可比或增强的药理学特征26在小鼠强迫游泳试验中也表现出强大的抗抑郁药样功效。有利的 ADMET 特征和26 的化学稳定性进一步表明,该化合物作为候选药物是有希望的,保证了药物发现管道的进一步发展。
