The piperazine ring of the potent nootropic drug DM235 has been decorated with H-bond donor and acceptor groups (CH2OH, CH2OMe, CH2OCOMe, COOEt); the aim was to insert new functional groups, suitable for further chemical manipulation. The influence of these modifications on nootropic activity was assessed by means of the mouse passive avoidance test; some of the newly synthesized molecules (alcohol
促智药物DM235的哌嗪环已用H键供体和受体基团(CH2OH,CH2OMe,CH2OCOMe,COOEt)装饰;目的是插入适合进一步化学操作的新官能团。通过小鼠被动回避试验评估了这些修饰对促智活性的影响。一些新合成的分子(酒精7b,乙酸8b和酯10d)显示出有趣的体内功效。这使得可以使用这些官能团来添加其他残基,以增加分子多样性,或用于锚定生物素基团,从而获得可用于捕获生物靶标的化合物。而且,新化合物将改善我们对该药物家族的结构活性关系的了解。
