either with alkyl or cycloalkyl substituents give compounds (1a-6a) with high affinity and selectivity for sigma1 binding sites. Compounds 1a-5a were further characterized in vivo, and their agonist/antagonist activity was evaluated. In mouse, compound 1a and 2a as well as haloperidol suppressed in a dose-related manner the stereotyped behavior induced by (+)-SKF 10,047. Compounds 3a-5a and (+)-pentazocine
已经描述了一系列(+)-顺-N-去甲甲唑嗪衍生物及其对sigma1,sigma2和苯环利定(PCP)位以及阿片样物质,毒蕈碱(M2),多巴胺(D2)和5-羟色胺(5-HT2)的亲和力)受体进行了评估。研究了用取代的乙氨基间隔基进行N取代的效果。化合物8c-11c对sigma1位点和阿片样物质受体表现出高亲和力。第二个碱性氮被烷基或环烷基取代基取代后,化合物(1a-6a)对sigma1的结合位点具有很高的亲和力和选择性。在体内进一步表征化合物1a-5a,并评估其激动剂/拮抗剂活性。在小鼠中,化合物1a和2a以及氟哌啶醇以剂量相关的方式抑制了由(+)-SKF 10047诱导的刻板行为。化合物3a-5a和(+)-戊唑嗪不影响通过腹膜内注射(+)-SKF 10047诱导的定型行为。因此,从这一系列化合物中,我们确定了有效的和选择性的sigma1配体,这些配体可能被证明对揭示sigma1位点的功能起作用。
