  摘要：

  In contrast to tropane-based compounds such as benztropine and cocaine, non-tropane-based photo-affinity ligands for the dopamine transporter (DAT) are relatively unexplored. Towards addressing this knowledge gap, ligands were synthesized in which the piperidine nitrogen of 3- and 4-iodomethylphenidate was substituted with a benzyl group bearing a photoreactive azide. Analog (+/-)-3a demonstrated modest DAT affinity and a radioiodinated version was shown to bind covalently to rat striatal DAT and hDAT expressed in cultured cells. Co-incubation of (+/-)-3a with nonradioactive D-(+)-methylphenidate or (-)-2-beta-carbomethoxy-3-beta-(4-fluorophenyl) tropane (beta-CFT, WIN-35,428, a cocaine analog) blocked DAT labeling. Compound (+/-)-3a represents the first successful example of a DAT photoaffinity ligand based on the methylphenidate scaffold. Such ligands are expected to assist in mapping non-tropane ligand-binding pockets within plasma membrane monoamine transporters. (C) 2010 Elsevier Ltd. All rights reserved.
