and 4'-position were also introduced. Novel compounds were tested for their binding affinity at the dopamine, serotonin, and norepinephrine transporter systems in the brain by competing for [(3)H]WIN 35 428, [(3)H]citalopram, and [(3)H]nisoxetine, respectively. Selected compounds were also evaluated for their activity in inhibiting the uptake of [(3)H]dopamine. Binding results demonstrated that alkenyl
合成了多巴胺转运蛋白(DAT)特异性化合物的一系列取代的N-苄基类似物4- [2-(2-(二苯基甲氧基)乙基] -1-苄基哌啶。将不同的4'-烷基,4'-烯基和4'-炔基取代基引入到苄基部分的苯环中,同时用相同的苯环用异构的α-和β-萘基取代。还介绍了3'和4'位置的不同极性取代基。通过竞争[(3)H] WIN 35428,[(3)H]西酞普兰和[(3)H]尼西西汀,对新型化合物在脑中多巴胺,5-羟色胺和去甲肾上腺素转运蛋白系统上的结合亲和力进行了测试, 分别。还评估了所选化合物在抑制[(3)H]多巴胺摄取中的活性。结合结果表明,在4'-位上的烯基和炔基取代产生了有效的化合物,其中具有乙烯基取代的化合物6是最有效的。对三种选定化合物的体内评估表明,尽管在DAT上具有很高的效力,但在相似的剂量范围内进行测试时,这些化合物刺激的运动活性(LMA)小于可卡因。在药物辨别研究程序中,这三种化合物均未从可卡因推广到可从媒介物中辨别10
