General description

A naturally isolated cell-permeable fungal resorcylic lactone that acts as a selective and highly potent inhibitor against the MAPKKK TAK1 activity (IC50 = 8 nM) in an ATP-competitive and irreversible manner, while inhibiting MEK1 (IC50 = 411 nM) and three other MAPKKKs (IC50 ≥268 nM against MEKK1, ASK1, and MEKK4) only 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. (5Z)-Zeaenol, Curvularia sp. (Cat. No. 499609) may serve as a negative control.

Preparation Note

Pathways and Biomarkers of Toll-like Receptor (TLR) Signaling

"Toll-like Receptors (TLRs) are transmembrane proteins that are expressed on various immune cells. The extracellular N-terminal region of TLRs recognizes specific pathogen components. At least 13 different members of TLR family have been identified that detect different pathogen associated molecular patterns (PAMPs), including lipopolysaccharides, flagellin, bacterial CpG DNA, and viral RNA and DNA. Recognition of PAMPs by TLRs is considered as a key process for the induction of an inflammatory response."
