can block the binding of cocaine to the dopamine transporter, yet spare dopamine uptake, a series of aromatic ring-substituted methylphenidate derivatives was synthesized and tested for inhibitory potency in [3H]WIN 35,428 binding and [3H]dopamine uptake assays using rat striatal tissue. Synthesis was accomplished by alkylation of 2-bromopyridine with anions derived from various substituted phenylacetonitriles
作为开发可阻断可卡因与多巴胺转运蛋白结合而又不吸收多巴胺的药物的计划的一部分,合成了一系列芳香环取代的哌醋甲酯衍生物,并测试了其对[3H] WIN 35,428结合和[使用大鼠纹状体组织的3H]多巴胺摄取测定。通过将2-溴吡啶与衍生自各种取代的苯基乙腈的阴离子进行烷基化来完成合成。在大多数情况下,赤型化合物的效力明显低于相应的(+/-)-苏式-甲基-哌醋甲酯(TMP;利他林)衍生物。邻位取代的化合物的效力远低于相应的间位和/或对位取代的衍生物。对抗[3H] WIN 35,428结合的最有效化合物,m-bromo-TMP,比母体化合物的效力高20倍,而对[3H]多巴胺摄取最有效的化合物m,p-dichloro-TMP则强32倍。具有m-或p-卤代取代基的Threo衍生物比TMP更有力,而给电子的取代基引起的变化很小或失去的效力很小。除m,p-dichloro-TMP(nH为2.0)外,所有导
