previously developed dopamine transporter (DAT)-specific ligands 4-[2-(diphenylmethoxy)ethyl]-1-[(4-fluorophenyl)methyl]piperidine, 1a, and 4-[2-(bis(4-fluorophenyl)methoxy)ethyl]-1-benzylpiperidine, 1b, by a nitrogen atom resulted in the development of the N-analogues 4-[2-((diphenylmethyl)amino)ethyl]-1-[(4-fluorophenyl)methyl]pi peridi ne, 4a, and 4-[2-((bis(4-fluorophenyl)methyl)amino)ethyl]-1-benzylpiperidine
我们先前开发的多巴胺转运蛋白(DAT)特异性配体4- [2-(二苯基甲氧基)乙基] -1-[(4-氟苯基)甲基]哌啶,1a和4- [2- (双(4-氟苯基)甲氧基)乙基] -1-苄基哌啶,1b通过氮原子导致N-类似物4- [2-(((二苯基甲基)氨基)乙基] -1-[(4 -氟苯基)甲基]哌啶4a和4- [2-((双(4-氟苯基)甲基)氨基)乙基] -1-苄基哌啶4b。在大鼠纹状体组织和表达克隆的人类转运蛋白的HEK-293细胞中对这些化合物的生物学评估表明,这些化合物对DAT具有很高的效力和选择性。因此,化合物4a对DAT的作用在大鼠纹状体组织和克隆的转运细胞中分别为9.4和30 nM,与这两种系统的血清素转运蛋白(SERT)相比,其对DAT的结合选择性分别为62和195。化合物4b同样显示出对DAT的高效力和选择性。因此,用4a,b中的N原子代替1a,b中的O原子对效价和选择性的影响很小。与GBR
