3-Propylxanthine is a xanthine derivative that antagonizes adenosine receptors (Kis = 44, 32, and 6.3 μM for A1, A2A, and A2B, respectively) and cAMP phosphodiesterase (Ki = 42 μM). Through these actions, 3-propylxanthine induces smooth muscle relaxation, blocks smooth muscle contraction and VEGF secretion driven by adenosine receptor agonists, and reduces bronchial hyperresponsiveness.
ChEBI: Xanthine bearing a propyl substituent at position 3. A bronchodilator, it is used for the symptomatic treatment of asthma and chronic obstructive pulmonary disease, and in the management of cerebrovascular insufficiency, sickle cell disease, and diabetic n
uropathy.
