PD 168568 dihydrochloride is a orally active and potent dopamine receptor D4 (DRD4) antagonist. PD 168568 dihydrochloride contains an isoindolinone and is selective for the D4 receptor versus D2 and D3, with Ki values of 8.8, 1842, and 2682 nM, respectively. PD 168568 dihydrochloride can be used for glioblastoma (GBM) research[1][2].

PD 168568 is a dopamine D4 receptor antagonist (Ki = 8.8 nM).1 It is selective for dopamine D4 over D2 receptors (Ki = 1,842 nM). PD 168568 (3 mg/kg) reverses amphetamine-induced hyperlocomotion in rats. It also inhibits the growth of glioblastoma neural stem cells when used at concentrations of 25 and 50 μM.2

D₄ Receptor: 8.8 nM (Ki); D₂ Receptor: 1842 nM (Ki); D₃ Receptor: 2682 nM (Ki)
