Description
A PDE4 inhibitor (IC50 = 0.31 nM); selective for PDE4 over PDE1, PDE2, PDE3, PDE5, and PDE7A in cell-free assays (IC50s = >100, 40, >100, 14, and >10 μM, respectively); inhibits superoxide production by guinea pig eosinophils and histamine-induced contraction in isolated guinea pig trachea (IC50s = 24 and 2 nM, respectively); inhibits eosinophil, neutrophil, lymphocyte, and TNF-α accumulation in bronchoalveolar lavage fluid (BALF) from ovalbumin-sensitized rats (ED50s = 23.8, 14.1, 19.5, and 14.4 μmol/kg, respectively); nhibits eosinophil, neutrophil, lymphocyte, and TNF-α accumulation in BALF from ovalbumin-sensitized rats (ED50s = 23.8, 14.1, 19.5, and 14.4 μmol/kg, respectively); inhibits ovalbumin-induced bronchoconstriction in a guinea pig model of asthma (ED50 = 0.033 mg/kg)
