In Vivo S 18986 is robust memory-enhancing effects in middle-aged animals compared with aged ones. S 18986 shows antiamnesic properties in middle-aged rodents in spatial memory models [1]. S 18986 (5-50 mg/kg; i.p.) significantly increases both the induction and the maintenance of 4 and 20 bursts tetanus-evoked potentiation[1]. Animal Model: Middle-aged (14-15-months-old) mice[1] Dosage: 0.3, 1, and 10 mg/kg Administration: p.o. Result: Showed antiamnesic properties in middle-aged rodents.
