Department of Pharmacology, Kurume University School of Medicine, Japan.

The effects of the benzamide derivatives, (-)-sulpiride, sultopride and nemonapride, on spontaneous and electrically evoked dopamine (DA) release from striatal slices of rats were investigated. Nemonapride at concentrations of 100 nM or higher caused a dose-dependent increase in spontaneous DA release from the slices. (-)-Sulpiride and sultopride had little effect on spontaneous DA release. The electrically evoked DA release was enhanced by (-)-sulpiride at concentrations of 100 nM or higher in the superfusate and reduced by nemonapride at 100 nM or higher. Sultopride caused a small increase in the evoked release of DA. The different activities of these drugs on DA release may account for the different clinical results they produce.

D003342	Corpus Striatum	Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
