Pardoprunox hydrochloride

Pardoprunox hydrochloride is a novel partial dopamine D2 and D3 receptor agonist and serotonin 5-HT1A receptor agonist, D2 (pKi = 8.1) and D3 receptor (pKi = 8.6) partial agonist and 5-HT1A receptor (pKi = 8.5) full agonist. (In Vitro) :Pardoprunox (SLV-308) hydrochloride acts as a potent but partial D2 receptor agonist (pEC50= 8.0 and pA2=8.4) with an efficacy of 50% on forskolin stimulated cAMP accumulation. At human recombinant dopamine D3 receptors, Pardoprunox hydrochloride acts as a partial agonist in the induction of [ (35) S]GTPgammaS binding (intrinsic activity of 67%; pEC50=9.2) and antagonized the dopamine induction of [ (35) S]GTPgammaS binding (pA2=9.0) . Pardoprunox hydrochloride acts as a full 5-HT1A receptor agonist on forskolin induced cAMP accumulation at cloned human 5-HT1A receptors but with low potency (pEC50=6.3) .
