disorders as well as the diversity of brain neuronal nicotine acetylcholine receptors (nAChRs) have suggested an opportunity to develop subtype-selective nAChR ligands for the treatment of specific CNS disorders with reduced side effect liabilities. We report a novel series of 3-pyridyl ether compounds which possess subnanomolar affinity for brain nAChRs and differentially activate subtypes of neuronal nAChRs
最近的证据表明胆碱能通道调节剂具有治疗中枢神经系统(CNS)疾病的治疗潜力以及脑神经元烟碱乙酰胆碱受体(nAChRs)的多样性,这表明有机会开发亚型选择性nAChR配体来治疗中枢神经系统疾病。减少副作用的特定中枢神经系统疾病。我们报告了一系列新型的3-吡啶醚化合物,对大脑nAChRs具有亚纳摩尔的亲和力,并差异性激活神经元nAChRs的亚型。描述了该系列主要成员的合成与构效关系,包括A-85380(4a),它对大鼠脑[(3)H]-(-)-胱氨酸结合位点和与尼古丁相比,对人alpha4beta2 nAChR亚型刺激离子通量的功效为163%,和A-84543(2a),与人类神经节型nAChRs相比,在刺激人alpha4beta2 nAchR亚型的离子通量方面显示出84倍的选择性。计算研究表明,可以实现4A的低能量构象异构体与(S)-尼古丁和(-)-依巴替丁的合理叠加。
