ABT-724 trihydrochloride is a potent and highly selective dopamine D4 receptor agonist with an EC50 of 12.4 nM for human dopamine D4 receptor. ABT-724 trihydrochloride is a potent partial agonist at the rat D4 (EC50 of 14.3 nM) and the ferret D4 receptor (EC50 of 23.2 nM), and has no effect on dopamine D1, D2, D3, or D5 receptors. ABT-724 trihydrochloride could be useful for the treatment of erectile dysfunction and has favorable side-effect profile[1].
ABT-724 exhibits a selective biochemical profile, as indicates by a lack of binding affinity for >70 neurotransmitter/uptake/ion channels including D2, D3, or D5 receptors up to a 10 μM concentration. A weak affinity to 5-HT1A receptors (Ki = 2780 nM) is observed. ABT-724 does not inhibit the PDE activity of PDE1, PDE5, or PDE6 at 10 μM concentrations[1].
ABT-724 (8.8 μg/kg; subcutaneous injection; daily; for 5 days; male adult Wistar rats) treatment dose-dependently facilitates penile erection when given s.c. to conscious rats[1].
