A series of novel diamine, amine-amide, and piperazinone analogues of N-[2-(bisarylmethoxy)ethyl]-N'-(phenylpropyl)piperazines, GBR 12909 and 12935, were synthesized and evaluated as inhibitors of presynaptic monoamine neurotransmitter transporters. The primary objective of the study was to determine the structural requirements for selectivity of ligand binding and potency for neurotransmitter reuptake
合成了一系列新型的N- [2-(双芳基甲氧基)乙基] -N'-(苯丙基)哌嗪二胺,胺-酰胺和哌嗪酮类似物GBR 12909和12935,并将其评估为突触前单胺神经递质转运蛋白的抑制剂。该研究的主要目的是确定配体结合的选择性和抑制神经递质再摄取的能力的结构要求。通常,目标化合物保留了转运蛋白的亲和力。然而,结构变化对再摄取抑制和转运蛋白选择性产生了显着影响。例如,通过用N,N'-二甲基丙基二胺部分代替GBR结构中的哌嗪环而制备的类似物在去甲肾上腺素(NE)转运蛋白位点(例如4和5)显示出增强的结合和再摄取抑制选择性。其中酰胺氮原子连接到GBR分子的芳烷基部分的同类物显示出中等的亲和力(K(i)= 51-61 nM)和对多巴胺转运蛋白(DAT)位点的选择性。相反,与哌嗪环的任一氮原子(例如25和27)相邻的羰基的引入不能很好地耐受。从制备的化合物中,选择类似物16用于进一步评估。使用该同类物,可卡因以20
