Herein we describe the design, synthesis, and structure–activity relationships (SARs) of a novel phenylcyclopropane series represented by 7 and 33b as antagonists of orexin 1 and orexin 2 receptors. With 4 serving as the initial lead for the development of orexin antagonists, exploration of SAR resulted in improved binding affinity for orexin 1 and orexin 2 receptors. Among the synthesized compounds
在本文中,我们描述了由7和33b代表的作为orexin 1和orexin 2受体拮抗剂的新型苯基环丙烷系列的设计,合成和结构-活性关系(SAR)。以4作为开发orexin拮抗剂的最初线索,对SAR的探索提高了对orexin 1和orexin 2受体的结合亲和力。在合成的化合物中,33b((-)- N-(5-氰基吡啶-2-基)-2-[((3,4-二甲氧基苯基)氧甲基] -2-苯基环丙烷甲酰胺)在动物中表现出有效的体外活性和口服功效睡眠测量实验。我们的研究结果表明,化合物33b 可以作为开发新的orexin受体拮抗剂的有价值的模板。
