ABT-724 is an agonist of dopamine D4 receptor(EC50: 12.4 nM)

D4:12.4 nM(EC50), D4 receptor:12.4 nM(EC50)

ABT-724 (maleate salt) was freshly prepared and administered to rats via s.c. injection into the back neck area (1 ml/kg injection volume). For intracerebroventricular (ICV) or intrathecal administrations, rats were allowed at least 1 week of recovery from surgery before behavioral testing. The compounds of interest were infused ICV (left lateral ventricle) in a 5-μl volume or 10 μl intrathecally. After the experiment was completed, infusion of 0.5% fast-green dye in saline solution and subsequent dissection were carried out to confirm the diffusion of the injection solution[1].
