生物活性:
Ropinirole (SKF 101468) is an orally active, potent D3/D2 receptor agonist with a Ki of 29 nM for D2 receptor. Ropinirole has pEC50s of 7.4, 8.4 and 6.8 for hD2, hD3 and hD4 receptors, respectively. Ropinirole has no affinity for the D1 receptors. Ropinirole has the potential for Parkinson's disease.

体内研究:
Ropinirole (0.1-10 mg/kg; i.p.) decreases intracranial self-stimulation (ICSS) thresholds and induces anxiolytic- and antidepressive-like effects without affecting motor activity or spatial memory.

体外研究:
Ropinirole has affinity for D3 receptors of 10-20 fold higher than the D2 and D4 receptors. Ropinirole is weakly active at alpha 2-adrenoceptors and 5-HT2 receptors but inactive at 5-HT1, benzodiazepine and gamma-aminobutyric acid receptors or alpha 1 and beta-adrenoceptors.
