A series of analogues related to 1-[2-(diphenylmethoxy)ethyl]-4-(3-phenylpropyl)piperazine (2) and 1-¿2-[bis(4-fluorophenyl)methoxy]ethyl¿-4-(3-phenylpropyl)piperazine (3) (GBR 12935 and GBR 12909, respectively), in which the piperazine moiety was replaced by bridged piperazines for structural rigidity, has been designed, synthesized, and evaluated for their ability to bind to the dopamine transporter
与1- [2-(二苯基甲氧基)乙基] -4-(3-苯基丙基)哌嗪(2)和1- [2- [双(4-氟苯基)甲氧基]乙基] -4-(3)有关的一系列类似物-苯基丙基)哌嗪(3)(分别为GBR 12935和GBR 12909),其中哌嗪部分被桥连哌嗪取代以提高结构刚性,已经设计,合成并评估了它们与多巴胺转运蛋白(DAT)结合的能力)并抑制(3)H标记的多巴胺(DA)的摄取。结合数据表明,化合物7和11为N-甲基苯基和N-丙基苯基-3,8-二氮杂[3.2。1] 3的双环辛烷类似物,对DAT的亲和力高(分别为IC(50)= 8.0和8.2 nM),相对于血清素转运蛋白(SERT),7对DAT的选择性高(88和93倍)分别用于结合和再摄取)。他们还在DA摄取抑制中显示线性活性,具有与3相似的结合和重摄取抑制曲线。N-吲哚甲基类似物16显示了该系列中最高的亲和力(IC(50)= 1.4 nM),增加了6
