Pricing Availability Delivery Time Qty
Cat.No. 2214 - ABT 724 trihydrochloride | C17H19N5.3HCl | CAS No. 587870-77-7
Description: Potent, selective D4 partial agonist; proerectile
Chemical Name: 2-[[4-(2-Pyridinyl)-1-piperazinyl]methyl]-1H-benzimidazole trihydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Potent dopamine D4 receptor partial agonist (EC50 = 12.4 nM; 61% efficacy vs. dopamine). Has no agonist activity at D2 receptors (EC50 > 10 μM). Selective in rats in vivo; produces penile erection following i.c.v. administration; increases intracavernosal pressure and potentiates the proerectile effects of sildenafil following s.c. administration. Displays minimal side effects.
