Ibudilast is a leukomene antagonist and phosphodiesterase inhibitor useful in the
treatment of bronchial asthma. It antagonizes leukotriene D4-induced contractions of
guinea pig ileum and tracheal muscles in virro, and inhibits eosinophil accumulation in
vivo.

용도
Inhibitors of phosphodiesterase 4 (PDE4), which catalyzes the hydrolysis of cAMP, have potential applications in a variety of diseases, including asthma. Ibudilast is an inhibitor of PDE4 (IC50 = 54-239 nM) that, at higher doses, also inhibits PDE3 and PDE5 (IC50 = 1,600-3,510 nM). Through this action, it suppresses the elaboration of mediators involved in asthma and inflammation.[Cayman Chemical]
생물학적 활성
Phosphodiesterase inhibitor (IC 50 values are 53, 35, 48, 12 and 10 mM for PDE Ia, II, III, IV and V respectively). Inhibits platelet aggregation and is an orally-active cerebral vasodilator, bronchodilator and antiallergic agent.
