Dopamine D3 receptor biased agonist. Preferentially signals via the G protein-dependent pathway (EC50 values for G protein and β-arrestin-dependent signaling are 1.1 and 50.2 μM, respectively). Exhibits selectivity for D3 over D2 receptors. Improves motor deficits in rodent Parkinson's disease models and ameliorates L-DOPA induced abnormal involuntary movements.
