(S)-(-)-Propranolol hydrochloride

Description

(S)-(-)-Propranolol is the active enantiomer of propranolol, a β-adrenergic receptor antagonist with log K_d values of -8.16, -9.08, and -6.93 for β₁, β₂, and β₃, respectively. It is also a non-specific serotonin receptor antagonist. Propanolol was one of the first β-adrenergic receptor blockers to be widely used in clinical practice for the treatment of hypertension, angina pectoris, and cardiac ischemia.
