Description | An inhibitor of p38α (IC50 = 39 nM) and p38β MAP kinases with 82 and 93% inhibition, respectively, in a kinase assay (1 µM); selective for p38α and 38β, lacking activity at p38γ, p38δ, ERK1/2, and JNK1 at 1 µM; inhibits IL-1β, TNF-α, IL-6, IL-8, and IL-10, but not IFN-γ release from human peripheral blood mononuclear cells (IC50s = 30, 5, 17, 4, 10, and >1,000 nM, respectively); decreases ear swelling in mouse models of allergic and chronic irritative contact dermatitis (0.5 mg/ear, topical) |
