Ropinirole (SKF 101468) is an orally active, potent D₃/D₂ receptor agonist with a K_i 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.

In Vitro

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^[1]^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

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^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
