A series of diazinylpiperidine compounds of Formula I ##STR1## wherein X is an ethylene chain or a 1,2-benzo ring; Y is carbonyl or methylene; R.sup.1 is hydrogen or lower alkyl; and Z is an R.sup.2, R.sup.3 -disubstituted diazinyl ring selected from pyridazine, pyrimidine, and pyrazine ring systems. Pharmacologic and neuroanatomical testing demonstrates that compounds of the series act to enhance cerebral function in mammals, particularly when there is a deficit in normal cerebral functioning. Specific pharmacologic test results indicate that compounds of Formula I possess cognition and memory enhancing activity.
一系列的二氮杂环哌啶化合物,其化学式为I式:##STR1## 其中,X为乙烯链或1,2-苯环;Y为羰基或亚甲基;R1为氢或较低的烷基;Z为从吡啶并、嘧啶并和吡嗪并系统中选择的R2,R3-二取代的二氮杂环环。药理学和神经解剖学测试表明,该系列化合物可增强哺乳动物的脑功能,特别是在正常脑功能有缺陷时。具体的药理学测试结果表明,I式化合物具有增强认知和记忆的活性。
