(±)-alpha-[[(tert-butyl)amino]methyl]-7-ethyl-2-benzofuranmethanol hydrochloride

Bufuralol hydrochloride (Ro 3-4787 hydrochloride) is a potent non-selective, orally active β-adrenoreceptor antagonist with partial agonist activity. Bufuralol hydrochloride is a CYP2D6 probe substrate.

A β-Adrenergic blocker with peripheral vasodilating activity. Antianginal; antihypertensive.

CYP2D6 substrate

Bufuralol hydrochloride is known to be a non-specific β-receptor inhibitor that has an affinity for β 1 and β 2 receptors. Furthermore, studies have reported that bufuralol hydrochloride can decrease isoproterenol peripheral resistance.

Bufuralol is widely used in the characterization of CYP2D6 activity, and possesses aromatic rings and a basic nitrogen that are characteristic of CYP2D6 substrates.

Bufuralol metabolism mediated by NADPH exhibits biphasic kinetics and is less efficient than that observed in the presence of cumene hydroperoxide (CuOOH) in and monkey intestines, in agreement with the observations in the livers.
