Diphylline 是一种A1/A2腺苷受体拮抗剂，也是环状核苷酸磷酸二酯酶抑制剂。它是一种黄嘌呤衍生物，具有支气管扩张和血管扩张作用，有用于治疗慢性支气管炎和肺气肿的潜力。

Dyphylline is a xanthine derivative. Dyphilline exerts bronchodilator effects and to a lesser extent vasodilator and diuretic properties. Dyphilline probably acts as a competitive inhibitor of phosphodiesterase which leads to an increase in intracellular cAMP. This results in relaxation of bronchial smooth muscle and other smooth muscles. Dyphylline may also antagonize adenosinereceptors. Dyphylline is used in the treatment of acute bronchial asthma, chronic bronchitis and emphysema.
