      Ibudilast(KC-404;AV-411;MN-166) is a relatively nonselective phosphodiesterase inhibitor which has been marketed for treating asthma.;Target: PDE;Ibudilast (3-isobutyryl-2-isopropylpyrazolo[1,5-a]pyridine) is a nonselective inhibitor of cyclic nucleotide phosphodiesterase (PDE). The inhibition of platelet aggregation and vasodilatation by ibudilast may be due to synergistic elevation of intracellular cyclic nucleotides and release of nitric oxide (NO) or prostacyclin from endothelium, rather than direct inhibition of PDE5 or PDE3. Another important property of ibudilast is its antiinflammatory activity possibly associated with potent inhibition of PDE4. Combined with its relaxing effects on bronchial smooth muscle, antiinflammatory actvity of ibudilast could favorably influence pathophysiology of asthma by antagonizing chemical mediators triggering asthmatic attacks [1, 2]. Ibudilast (AV-411) is a non-selective phosphodiesterase inhibitor that is also known to suppress glial cell ac MedChem Express HY-B0763
