[Neurotropic activity of phenylpyrrolidones-2].
Experiments were conducted on mice and rats; a study was made of the pharmacological activity of three isomers of phenyl derivatives of pyrrolidone-2 (P-2). The latter represented a cylic form of gamma-aminobutyric acid (GABA). All the three preparations suppressed the motor activity, decreased the muscle tone and the body temperature, potentiated the action of hexenal, possessed the antispasmodic and hypnotic activity. 4-phenyl-pyrrolidone-2 (phepyron) proved to be most active. In comparing the pharmacological activity of phenyl P-2 derivatives and analogous GABA derivatives the latter were found to possess no antispasmodic or hypnotic activity, and were less toxic. It is supposed that no transformation of phenyl P-2 derivatives into analogous GABA derivatives occurred in the organism.
