GSK598809 is a potent and selective dopamine D3 Receptor (DRD3) antagonist, with a pKi of 8.9.

IC50 & Target

pKi: DRD3[1][2].

In Vivo

Cocaine and GSK598809 each increases peak mean arterial blood pressure. Least square mean differences are significant for both doses of cocaine compared with its vehicle. Likewise, least square mean differences are significant for both doses of GSK598809 as compared with its vehicle. The experimental question of interest, that is, whether GSK598809 significantly increases cocaine effects on peak mean arterial blood pressure, is probed by a prior it tests on the means of the fitted regression model. The dose of 3 mg/kg GSK598809 significantly increases the pressor effects of 5.6 mg/kg cocaine and of 1.7 mg/kg cocaine[1].

Animal Administration

Male beagle dogs are used throughout the study. The experiment is conducted in phases. In the first (hemodynamics) phase, the dogs are dosed at weekly intervals over a period of 9 weeks with combinations of either GSK598809 or vehicle, followed by either cocaine or vehicle. After the baseline measurements are recorded, technical staff briefly returns to the animal room to administer GSK598809 (or vehicle) to all the dogs via oral gavage and activate the timers on the preloaded and preprogrammed infusion pumps[1].
