The psycho- and neurotropic profiling of novel 3-(N-R,R′-aminomethyl)-2-methyl-1H-quinolin-4-ones in vivo

The article presents the study of psycho- and neurotropic properties of novel 3-(N-R,R′-aminomethyl)-2-methyl-1H-quinolin-4-ones in vivo. The research was carried out using the open field test, elevated plus maze, rotarod test, tail suspension test, passive avoidance test after scopolamine-induced amnesia and acute normobaric hypoxia with hypercapnia. As a result, two promising substances have been found. According to our results 3-[[(4-methoxyphenyl)amino]methyl]-2-methyl-1H-quinolin-4-one in the dose of 10 mg/kg shows a specific sedative effect and a considerable anti-amnesic activity. The most interesting N-[(2-methyl-4-oxo-1H-quinolin-3-yl)methyl]-N-phenylbenzamide (100 mg/kg) combines a potent anti-anxiety action, the anti-amnesic activity and a considerable antihypoxic effect. They are of interest for further profound studies as promising psychoactive compounds.
