as exists in cocaine and methylphenidate, is essential for interaction with monoamine transporters. We previously demonstrated that an amine nitrogen in phenyltropane analogues of cocaine is not necessary for conferring high DAT binding affinity. We now report the synthesis of oxacyclic and carbacyclic analogues of methylphenidate, including the four enantiomerically pure isomers of 2-(3,4-dichlorop
哌醋甲酯(利他林)与多巴胺转运蛋白(DAT)立体选择性和对映选择性结合,并在体外和体内的效价类似于可卡因,抑制多巴胺的再摄取。与可卡因不同,它几乎没有表现出容忍或成瘾的责任。由于该化合物具有丰富的临床历史,因此可提供出色的模板,从中可以设计可卡因滥用的潜在药物。长期以来,人们一直认为氮(例如可卡因和哌醋甲酯中存在的氮)对于与单胺转运蛋白的相互作用必不可少。我们先前证明,可卡因的苯tropane类似物中的胺氮对于赋予高DAT结合亲和力不是必需的。现在,我们报告了哌醋甲酯的氧环和碳环类似物的合成,包括2-(3,4-二氯苯基)-2-(四氢吡喃-2-基)乙酸甲酯的四个对映体纯的异构体。苏式异构体是DAT的有效和选择性抑制剂。这是氮的存在对DAT抑制不是必需的原理的第一个概括。
