Inhibitor of the JNK/p38 pathways. Inhibits anisomycin-induced but not TNF-induced JNK/p38 activation. Potent protein kinase inhibitor.
A naturally isolated cell-permeable fungal resorcylic lactone that acts as a selective and highly potent inhibitor against the MAPKKK TAK1 activity (IC50 = 8nM) in an ATP-competitive and irreversible manner; also inhibits MEK1 (IC50 = 411nM) and three other MAPKKKs (IC50 ≥268 nM against MEKK1, ASK1, and MEKK4) but at much higher concentrations. Shown to inhibit IL-1-induced/TAK1-mediated, but not H2O2-induced/TAK1-independent, JNK and p38 phosphorylation in 293 cells.
