rimcazole, binds with moderate affinity (K(i)=224nM) to the DAT. The results from previous SAR studies suggested that substitution of the carbazole ring system of rimcazole with bis-(4'-fluorophenyl)amine might improve binding affinity and selectivity for the DAT. Thus, a novel series of [3-cis-3,5-dimethyl-(1-piperazinyl)alkyl]bis-(4'-fluorophenyl)amines were synthesized. The most potent compound in this
在不断努力确定用于研究
多巴胺转运蛋白(
DAT)的新型探针中,我们发现sigma受体拮抗剂rimcazole以中等亲和力(K(i)= 224nM)与
DAT结合。先前
SAR研究的结果表明,用双-(4'-
氟苯基)胺取代rimcazole的
咔唑环系统可能会改善
DAT的结合亲和力和选择性。因此,合成了一系列新的[3-顺式-3,5-二甲基-(1-
哌嗪基)烷基]双-(4′-
氟苯基)胺。该系列中最有效的化合物(9b)取代了大鼠尾状-丘脑(K(i)= 17.6nM)中的[3H] WIN 35,428结合,具有与GBR 12909相当的亲和力。尽管在
DAT上具有高亲和力结合,并且与GBR 12909,
