A series of novel fluoroalkyl-containing tropane derivatives (6-8, 10-14, 17, and 18) were synthesized from cocaine. Novel compounds were evaluated for affinity and selectivity in competitive radioligand binding assays selective for cerebral serotonin (5-HT), dopamine (DA), and norepinephrine (NE) transporters (SERT, DAT, and NET). The nortropane-fluoroalkyl esters (7, 10, 11) were most potent for
从可卡因合成了一系列新颖的含氟烷基的托烷衍生物(6-8、10-14、17和18)。在竞争性放射性配体结合测定法中对脑5-羟色胺(5-HT),多巴胺(DA)和去甲肾上腺素(NE)转运蛋白(SERT,DAT和NET)有选择性,对新型化合物的亲和力和选择性进行了评估。降冰片烷-氟代烷基酯(7、10、11)对SERT最有效(K(i):分别为0.18、0.24和0.30 nM)。甲苯磺酸酯17和18,合成为[(18)F]标记的正电子发射断层扫描(PET)成像剂的前体,也显示出对DAT的高亲和力。
