[Effect of psychotropic substances and gamma-aminobutyric acid analogs and derivatives on the release of 3H-D-aspartic acid from perfused synaptosomes of the rat cerebral cortex].

It was shown in experiments in vitro that neuroleptics haloperidol and sulpiride, antidepressants desipramine and amitriptyline, nootropic agent piracetam, benzodiazepine tranquillizer phenazepam, psychostimulant phenamine and agonist of GABA A-receptors tetrahydroisoxazolopyridinol depending on the concentration in the micromolar range decrease K+-stimulated release of 3H-D-aspartic acid from rat brain cortex synaptosomes. Agonists of GABA B-receptors phenibut and baclofen as well as valproate and sodium oxybutyrate failed to exert a noticeable effect on the process under study.
