and MN19, characterized by rings with different size, have been prepared and evaluated for their nootropic activity in the mouse passive-avoidance test. It was found that the optimal ring size for the analogs of DM235, showing endocyclic both amidic groups, is 6 or 7 atoms. For the compounds structurally related to MN19, carrying an exocyclic amide group, the piperidine ring is the moiety which gives
已制备了一系列DM235和MN19的类似物,其特征是具有不同大小的环,并在小鼠被动回避测试中评估了它们的促智活性。已经发现,DM235类似物的最佳环尺寸为6或7个原子,显示环内两个酰胺基。对于结构上与MN19相关,带有环外酰胺基的化合物,哌啶环是产生最有趣化合物的部分。
