The molecule is the hydrochloride form of propranolol, a synthetic beta-adrenergic receptor blocker with antianginal, antiarrhythmic, and antihypertensive properties. Propranolol competitively antagonizes beta-adrenergic receptors, thereby inhibiting beta-adrenergic reactions, such as vasodilation, and negative chronotropic and inotropic effects."}, {"from": "gpt", "value": "[C][C][Branch1][C][C][N][C][C][Branch1][P][C][O][C][=C][C][=C][C][=C][C][=C][C][=C][Ring1][=Branch1][Ring1][#Branch2][O].[Cl]"}]
