Ibudilast Chemical Properties,Usage,Production

Chemical Properties
White Solid
a phosphodiesterase inhibitor with anti-inflammatory activity
A leukotriene D4 antagonist. Used as an antiallergic, antiasthmatic, and vasodilator (cerebral)
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]
Biological Activity
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.
