4-Aminopiperidine derivatives as a new class of potent cognition enhancing drugs
摘要:
Extrusion of one of the nitrogens of the piperazine ring of potent nootropic drugs previously described gave 4-amino-piperidine analogues that maintained high cognition enhancing activity in the mouse passive avoidance test. One of the new compounds (9. active at 0.01 mg/kg ip) may represent a new lead for the development of cognition enhancers useful to treat the cognitive deficit produced by neurodegenerative pathologies like Alzheimer's disease.
