Pardoprunox (INN) (code name SLV-308) is an antiparkinsonian drug currently that was under development by Solvay for the treatment of Parkinson's disease that reached phase III clinical trials before being discontinued.[1][2][3][1] It was also being investigated for the treatment of depression and anxiety but these indications appear to have been abandoned as well.[1]

Pardoprunox acts as a D2 (pKi = 8.1) and D3 receptor (pKi = 8.6) partial agonist (IA = 50% and 67%, respectively) and 5-HT1A receptor (pKi = 8.5) full agonist (IA = 100%).[1][4] It also binds to D4 (pKi = 7.8), α1-adrenergic (pKi = 7.8), α2-adrenergic (pKi = 7.4), and 5-HT7 receptors (pKi = 7.2) with lower affinity.[1][4] Relative to other dopaminergic antiparkinsonian agents, pardoprunox is thought to have significantly less of a propensity for inducing certain side effects like dyskinesia and psychosis.[4][5]
