Oxygenated Analogues of 1-[2-(Diphenylmethoxy)ethyl]- and 1-[2-[Bis(4-fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazines (GBR 12935 and GBR 12909) as Potential Extended-Action Cocaine-Abuse Therapeutic Agents

An investigation into the preparation of potential extended-release cocaine-abuse therapeutic agents afforded a series of compounds related to 1-[2-(diphenylmethoxy)ethyl]-4-(3-phenylpropyl)piperazine (1a) and 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazine (1b) (GBR 12935 and GBR 12909, respectively), which were designed, synthesized, and evaluated for their ability to bind to
对潜在的可卡因滥用滥用治疗剂的制备进行了研究,得到了一系列与1- [2-(二苯基甲氧基)乙基] -4-(3-苯基丙基)哌嗪(1a)和1- [2- [双(4-氟苯基)甲氧基]乙基] -4-(3-苯基丙基)哌嗪(分别为GBR 12935和GBR 12909),已设计,合成并评估了其与多巴胺转运蛋白的结合能力(DAT)并抑制[(3)H]标记的多巴胺(DA)的摄取。在1a-1d的苯丙基部分的苯环上加成羟基和甲氧基取代基会产生一系列有效的DAT配体(选择性5-28)。包括羟基以将中链羧酸酯结合到分子中,形成油溶性前药,适合“长效” 注射技术。在丙基侧链上引入含氧官能团后,得到的酮29和30大大降低了对DAT的亲和力,并降低了抑制[(3)H] DA和苯甲醇31-36的吸收能力,它们在结合DAT和抑制[(3)H] DA摄取方面具有很高的效力和选择性。32个对映体(34和36)在生物学测试中几乎相同。化合
