Ritobegron (also known as KUC-7483) is a potent and selective β3-adrenergic receptor agonist. In studies involving transfected human β-AR, Ritobegron exhibits significant and selective agonistic activity towards β(3)-AR. In rats, it shows high selectivity for the bladder over other organs. In anesthetized rats, Ritobegron effectively reduces bladder pressure with minimal impact on the cardiovascular system. It holds potential as a compound for treating overactive bladder.
