SCH 23390, an apparently selective antagonist of central D 1 dopamine receptors, produced profound catalepsy at low doses (0.1 mg/kg, sc). Pretreatment with the selective D 2 receptor agonists LY 141865, RU 24213 or LY 171555, the active (−) enantiomer of LY 141865, elicited a dose-dependent inhibition of the cataleptic response. Pergolide and apomorphine were also effective. This effect was not due to altered disposition or penetration of SCH 23390 into the brain since pretreatment with a dose of LY 171555 which completely blocked catalepsy had no effect on the ID 50 of SCH 23390 to inhibit 3 H-cis-piflutixol binding to D 1 receptors measured ex vivo. Alternative mechanisms are considered to explain the results, which offer new insights into striatal dopaminergic regulation of motor activity.
