Non-tropane-based photoaffinity ligands for the dopamine transporter (DAT) are relatively unexplored in contrast to tropane-based compounds such as cocaine. In order to fill this knowledge gap, a ligand was synthesized in which the aromatic ring of pyrovalerone was substituted with a photoreactive azido group. The analog 1-(4-azido-3-iodophenyl)-2-pyrrolidin-1-yl-pentan-1-one demonstrated appreciable binding affinity for the DAT (K(i)=78+/-18 nM), suggesting the potential utility of a radioiodinated version in structure-function studies of this protein.
与可卡因等基于托烷的化合物相比,用于多巴胺转运体(DAT)的非托烷类光亲和配体相对较少被研究。为了填补这一知识空白,合成了一种配体,其中吡咯戊酮的芳香环被光反应性叠氮基取代。类似物1-(4-叠氮基-3-碘苯基)-2-吡咯烷-1-基-戊-1-酮对DAT表现出可观的结合亲和力(K(i)=78±18 nM),这表明放射性碘化版本在该蛋白质的结构-功能研究中具有潜在用途。
