Ritobegron HCl

    WARNING: This product is for research use only, not for human or veterinary use.

Hodoodo CAT#: H319598

CAS#: 476333-91-2 (HCl)

Description: Ritobegron, also known as KUC-7483, is a potent and selective β3-adrenoceptor agonist. Ritobegron displayed potent and selective β(3)-AR agonistic activity toward transfected human β-AR and exhibited a high selectivity for the bladder versus other organs in rats. Ritobegron decreased intravesical pressure with minimal effects on the cardiovascular system in anesthetized rats. Ritobegron shows promise as a potential agent for the treatment of overactive bladder.
