Abstract
The binding of the D1 antagonist SCH23390 to membrane preparations from rat cerebral cortex was examined using enantiomers of dopamine agonists and antagonists to compete with the bound [3H]SCH23390 at its Kd value. The competition curves were compared with those obtained with preparations from the neostriatum. The results demonstrate that specific [3H]SCH23390 binding in the cerebral cortex has the same pharmacological profile as in the neostriatum, so that this radioligand can be used to label dopamine D1 receptors in brain regions with a sparse dopaminergic innervation.
