selectivity for the Dopamine transporter. In order to evaluate the potential of such a compound as an imaging tool for studying the dopaminergic system by Positron Emission Tomography (PET) the cold fluoroethyl BTCP piperazine 6 was synthesized. After checking the biological activity of the cold compound 6, the [ 18 F] analogue 7 was synthesized. The radiosynthesis was carried out by the nucleophilic substitution
BTCP 衍生物 1-11-(2-benzo[b] thiophenyl) cyclohexyl]-4-(2-hydroxyethyl) piperazine 2 在体外对多巴胺转运蛋白显示出高亲和力和选择性。为了评估这种化合物作为通过正电子发射断层扫描 (PET) 研究多巴胺能系统的成像工具的潜力,合成了冷氟乙基 BTCP 哌嗪 6。检测冷化合物6的生物活性后,合成了[ 18 F]类似物7。放射合成是通过 1-[1-(2-苯并[b] 噻吩) 环己基]-4-(2-氯乙基)哌嗪 5 与回旋加速器产生的 nca 18 F - 亲核取代来进行的,由 (p ,n) 在富含 18 O 的水中反应。
