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Formula I的二氮基哌啶化合物,其中X是乙烯链或1,2-苯环;Y是羰基或亚甲基;R.sup.1是氢或较低的烷基;Z是选择自吡啶嗪、嘧啶和吡嗪环系统的R.sup.2,R.sup.3-二取代的二氮基环。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大脑功能,特别是在正常大脑功能存在缺陷时。具体的药理学测试结果表明,Formula I的化合物具有认知和记忆增强活性。
