Piperidine Analogues of 1-[2-[Bis(4-fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazine (GBR 12909): High Affinity Ligands for the Dopamine Transporter
摘要:
A series of 4-[2-[bis(4-fluorophenyl)methoxy]ethylpiperidines were examined for their ability to bind to the dopamine transporter (DAT), the norepinephrine transporter, and the serotonin transporter (SERT). In particular, the role of the N-substituent on affinity and selectivity for the DAT was probed. 4-[2-[Bis(4-fluorophenyl)methoxy]ethyl-1-(2-naphthylmethyl)piperidine was found to possess subnanomolar affinity (K-i = 0.7 nM) and good selectivity for the DAT (SERT/DAT = 323).

Molecular structural modifications of 4-[2-(diphenylmethoxy)ethyl]-1-(3-phenylpropyl)piperidine (1a), a dopaminetransporter (DAT)-specific ligand, generated several novel analogues. Biological activities of these new molecules for their binding to the DAT and serotonintransporter (SERT) were evaluated in rat striatal membranes. Some of these new analogues were more potent and selective than GBR 12909
多巴胺转运蛋白(DAT)特异性配体4- [2-(二苯基甲氧基)乙基] -1-(3-苯基丙基)哌啶(1a)的分子结构修饰产生了几种新的类似物。在大鼠纹状体膜中评估了这些新分子与DAT和血清素转运蛋白(SERT)结合的生物学活性。当比较它们相对于SERT与DAT的结合时,其中一些新的类似物比GBR 12909更有效和更具选择性。因此,化合物9和19a是该系列中最有效的化合物(分别为IC50 = 6.6和6.0 nM)和选择性化合物(DAT / SERT = 33.8和30.0),它们的活性比GBR 12909(IC50 = 14)高nM,DAT / SERT = 6.1)。在这些分子的N-丙基侧链中引入双键不会在很大程度上影响其活性。
