[C][C][N][C][C][Branch1][N][C][=C][C][=Branch1][=Branch1][=C][C][=C][Ring1][=Branch1][O][O]"}, {"from": "gpt", "value": "The molecule is an adrenergic agonist with vasoconstrictive activity. Etilefrine selectively binds to and activates alpha-1-adrenergic receptors of the arteriolar and venous vasculature. This causes smooth muscle contraction and leads to a decrease in venous pooling and increase in blood pressure. This agent may also stimulate beta-1 adrenergic receptors, leading to positive chronotropic and inotropic effects."}]
