Biological Activity

ABT 724 is a potent dopamine D4 receptor partial agonist (EC50 = 12.4 nM; 61% efficacy vs. dopamine), which displays no agonist activity at D2 receptors (EC50 > 10 μM). ABT 724 is selective in rats in vivo and produces penile erection following i.c.v. administration, and increases intracavernosal pressure and potentiates the proerectile effects of sildenafil following s.c. administration. This compound displays minimal side effects.
