Notes: 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).{27926,33858,29142} 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.{33856,33857,33858}
