[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a lipophilic, nonselective beta-adrenergic receptor antagonist with anti-arrhythmic, anti-anginal and antihypertensive activities. Oxprenolol competitively binds to and blocks beta-1 adrenergic receptors in the heart, thereby decreasing cardiac contractility and rate. This leads to a reduction in cardiac output and lowers blood pressure. In addition, oxprenolol prevents the release of renin, a hormone secreted by the kidneys that causes constriction of blood vessels."}, {"from": "gpt", "value": "[C][C][Branch1][C][C][N][C][C][Branch1][#C][C][O][C][=C][C][=C][C][=C][Ring1][=Branch1][O][C][C][=C][O]"}]
