N-[(tetralin-1-yl)alkyl]piperidines and a number of related N-di-n-propyl-[(tetralin-1-yl)alkyl]amines were prepared. Structural modifications such as piperidine substitutions, intermediate chain lengthening, and the nature of the aromatic ring were explored in order to identify structural requirements for selective sigma 1 affinity. They were tested in radioligand binding assays on sigma 1, 5-HT1A and 5-HT2
制备了一系列取代的N-[(四氢-1-基)烷基]哌啶和许多相关的N-二-正丙基-[(四氢-1-基)烷基]胺。为了确定选择性sigma 1亲和力的结构要求,对诸如哌啶取代,中间链加长和芳环性质等结构修饰进行了研究。在放射性配体结合测定中对它们进行了测试,其中包括sigma 1、5-HT1A和5-HT2血清素能,PCP(苯环利定)和D-2多巴胺能受体。此处报道的几乎所有化合物均显示出高至超强的sigma 1亲和力,并且某些化合物还表现出比其他受体广泛的选择性。在[3H]-(+)-戊唑啉结合中,3,3-二甲基-1- [3-(5-甲氧基-1,2,3,4-四氢萘-1-基)-正丙基]哌啶(24 )和3,3-二甲基-1- [4-(1,2,3,4-四氢萘-1-基)正丁基哌啶(26)达到最低的Ki值(分别为0.4和0.8 nM)。化合物24还表现出相当大的PCP亲和力(Ki = 34.2 nM),而化合物26
