Background

(5Z)-7-Oxozeaenol (CAS: 253863-19-3) is a naturally occurring resorcylic lactone obtained from fungal sources. It functions as a selective inhibitor of transforming growth factor β-activated kinase 1 (TAK-1), a member of the mitogen-activated protein kinase kinase kinase (MAPKKK) family. In biochemical assays, (5Z)-7-Oxozeaenol inhibits purified TAK-1 with an IC50 of approximately 8.1 nM, exhibiting minimal activity against related MAPKKKs. Cellular studies indicate irreversible blockade of IL-1-stimulated TAK-1, NF-κB, and JNK/p38 signaling pathways. This molecule is useful in inflammation research, as demonstrated by its suppression of IL-1-induced COX-2 production and attenuation of inflammatory responses in mouse models.

Protocol

Cell experiment:[1]

Cell lines

Mouse embryonic fibroblast cells

Reaction Conditions

500 nM (5Z)-7-oxozeaenol for 17.5 h incubation

Applications

In cell culture, (5Z)-7-oxozeaenol blocked interleukin-1-induced activation of TAK1, JNK/p38 MAPK, IκB kinases, and NF-κB, resulting in inhibition of cyclooxgenase-2 production.

Animal experiment:[1]

Animal models

Mice repeatedly sensitized by picryl chloride (PC) and subsequently challenged with PC

Dosage form

10 μl of (5Z)-7-oxozeaenol (1 mg/ml)

Painted on each ear 2 h before and 4 h after the second PC challenge (total of twice) or every hour three times before and 4 h after the second PC challenge (total of four times)

Applications

When (5Z)-7-oxozeaenol was administrated to the PC-challenged ear, ear swelling was reduced by up to 50% of that of the control ear treated with vehicle. Thus, (5Z)-7-oxozeaenol was able to prevent inflammation by inhibiting the catalytic activity of TAK1 MAPKKK.
