title: Effect of di-n-propylacetate on the 'binding of GABA to synaptosome-enriched fraction of rat cerebral cortex.
abstract: The effect of di-n-propylacetate (DPA) on the 'binding' of gamma-aminobutyric acid (GABA) to a synaptosome-enriched fraction of rat cerebral cortex has been examined using differential centrifugation and double-isotope liquid scintillation spectrometry. DPA at 10(-4) M caused a slight decrease in GABA binding. This effect could explain in part the in vivo anticonvulsant and behavioral effects of this drug when administered to animals in high systemic doses.
