The interactions of the "antidementia drug" pantoyl-gamma-aminobutyric acid (pantoyl-GABA) with gamma-aminobutyric acid (GABA) receptors were investigated by studies on bindings of radiolabelled ligands in rat brain. Pantoyl-GABA inhibited the binding of [3H]GABA to GABAA receptors and those of [3H]baclofen and [3H]GABA to GABAB receptors in the rat cerebral cortex. These data suggest that pantoyl-GABA interacts with both types of GABA-receptors in the rat brain.
