FE-β-CIT (8-(2-fluoroethyl)-3-(4-iodophenyl)-8-azabicyclo[3.2.1]octane-2-carboxylic acid methyl ester) (1) and PR04.MZ(8-(4-fluorobut-2-ynyl)-3-p-tolyl-8-azabicyclo[3.2.1]octane-2-carboxylic acid methyl ester) (2) were labelled with (18)F-fluorine using a two-step route. 2-[(18)F]Fluoroethyltosylate and 4-[(18)F]fluorobut-2-yne-1-yl tosylate were used as labelling reagents, respectively. Radiochemically
可卡因衍生的多巴胺再摄取抑制剂 FE-β-CIT(8-(2-氟乙基)-3-(4-碘苯基)-8-氮杂双环 [3.2.1] 辛烷-2-羧酸甲酯)(1)和PR04.MZ(8-(4-fluorobut-2-ynyl)-3-p-tolyl-8-azabicyclo[3.2.1]octane-2-羧酸甲酯)(2)用(18)F-标记氟使用两步法。2-[(18)F] Fluoroethyltosylate 和 4-[(18)F]fluorobut-2-yne-1-yl tosylate 分别用作标记试剂。在约 25% 的非化学物质中合成 100 分钟后获得放射化学纯 (>98%) [(18)F]FE-β-CIT 和 [(18)F]PRD04.MZ (32-86 GBq/µmol) - 衰减校正的总产量。
