(ERG2), we previously deduced a basic sigma-1 receptor pharmacophore or chemical backbone composed of a phenyl ring attached to a di-substituted nitrogen atom via an alkyl chain.2 Here, we report the design and synthesis of various N,N-dialkyl or N-alkyl-N-aralkyl derivatives based on this pharmacophore as well as their binding affinities to the sigma-1 receptor. We introduce three high affinity sigma-1
sigma-1 受体是一种独特的非阿片类药物、非 PCP 结合位点,与许多不同的病理生理状况有关,包括精神病、药物成瘾、视网膜变性和癌症。基于芬丙吗啉的结构、高亲和力 ( K i = 0.005 nM) 1 sigma-1 受体配体和酵母甾醇异构酶 (ERG2) 的强抑制剂,我们之前推断出基本的 sigma-1 受体药效团或化学骨架由通过烷基链连接到双取代氮原子的苯环。2在这里,我们报告了各种N,N-二烷基或N-烷基-N的设计和合成-基于该药效团的芳烷基衍生物以及它们与 sigma-1 受体的结合亲和力。我们介绍了三种高亲和性 sigma-1 受体化合物,N,N -dibutyl-3-(4-fluorophenyl)propylamine ( 9 ), N,N -dibutyl-3-(4-nitrophenyl)propylamine ( 3 ), and N -丙基ñ '-4-氨基苯乙
