A number of N-substituted 4-hydroxy-, 4-acyloxy- and 4-alkoxy-2-pyrrolidinones were examined by a screening method predictive of their activity on cognitive processes. The 1-aminocarbonylmethyl-substituted compounds showed a favorable effect on learning and memory, and among them the most active was the

The cardiovascular effects of i.v. gamma-amino-beta-hydroxybutyric acid (GABOB) were investigated in rats anaesthetized with urethane. GABOB produced a dose-dependent hypotensive response. Treatment with GABA-A receptor antagonists prevented the GABOB response while the GABA stimulation by diazepam enhanced this response. The
