    摘要： A series of nootropic compounds of the following formula: ##STR1## and its pharmaceutically acceptable acid addition salts, wherein: R.sup.2 is hydrogen, lower alkyl, aryl which is optimally substituted, or hetaryl;R.sup.7 is hydrogen or is combined with R.sup.9 as a fused benzo-ring;R.sup.8 is hydrogen or lower alkyl; andR.sup.9 is lower alkyl, or R.sup.9 can be combined with R.sup.8 to give a 2-pyrrolidinone, a phthalimide, or isoindolone ring system.Pharmacological testing demonstrates that the series possesses cognition and memory enhancing actions and/or mild CNS simulation.

    摘要： 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.
