| Bioactivity | ABT-724 is a potent and highly selective dopamine D4 receptor agonist with an EC50 of 12.4 nM for human dopamine D4 receptor. ABT-724 is a potent partial agonist at the rat D4 (EC50 of 14.3 nM) and the ferret D4 receptor (EC50 of 23.2 nM). ABT-724 has no effect on dopamine D1, D2, D3, or D5 receptors. ABT-724 could be useful for the treatment of erectile dysfunction and has favorable side-effect profile[1]. |
| Target | EC50: 12.4 nM (Human dopamine D4 receptor), 14.3 nM (Rat dopamine D4 receptor) and 23.2 nM (Ferret dopamine D4 receptor) |
| Invitro | 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]. |
| In Vivo | 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]. Animal Model: |
