RS/SR diastereomers showed substantial activity when the phenyl substituent was 3,4-dichloro. On a locomotor assay, one compound was found to have a slow onset and a long duration of action. The activity of these compounds provides additional evidence for a conformational/superposition model of methylphenidate with cocaine-like structures. A ketone analogue, obtained by hydrogenating a previously described
已合成并通过单胺转运蛋白测定法测试了哌甲酯甲酯类似物,其中的甲氧羰基被烷基取代,并具有不同的苯基取代基。如从药效基团模型预测的那样,大多数RR / SS非对映异构体均显示出作为多巴胺重摄取抑制剂的高效力。具有4-氯苯基基团和未分支的初始烷基原子的类似物始终增强了对多巴胺转运蛋白的选择性。最有效的化合物是具有三或四碳链的化合物。当苯基取代基为3,4-二氯时,“非活性” RS / SR非对映异构体显示出明显的活性。在运动测定中,发现一种化合物起效缓慢且作用时间长。这些化合物的活性为具有可卡因样结构的哌醋甲酯的构象/叠加模型提供了额外的证据。通过氢化前述的乙烯基酰胺获得的酮类似物具有与哌醋甲酯相似的活性。
