CAS:O-Desmethyl metoprolol, a metabolite of metoprolol, acts as a β1-adrenergic receptor (β1-AR) antagonist. This compound is produced through the metabolism of metoprolol by the cytochrome P450 (CYP) isoform CYP2D6.Formula:C14H23NO3Color and Shape:SolidMolecular weight:253.342O-Desmethyl metoprolol
CAS:O-Desmethyl metoprolol is an active metabolite of metoprolol. It has an inhibitory effect on beta-adrenergic receptors and acts as a vasodilator. O-Desmethyl metoprolol is formed by the action of cytochrome P450 on the parent drug, which has a strong acidic nature and is easily soluble in water. This metabolite can be detected in urine samples using a chromatographic method with detection sensitivity of 1 ng/mL. The stereoselectivity of the parent drug and its active metabolite is different, with the former being more selective for beta1 receptors while the latter is more selective for beta2 receptors. O-Desmethyl metoprolol may have clinical relevance because it was found to decrease blood pressure in hypertensive patients when given at doses that are much lower than those needed for its parent drug. The concentration of this metabolite in plasma was found to be proportional to dosage level and kinetic data suggest
