Chemical Name: (3S,5Z,8S,9S,11E)-3,4,9,10-tetrahydro-8,9,16-trihydroxy-14-methoxy-3-methyl-1H-2-benzoxacyclotetradecin-1,7(8H)-dione
Biological Activity(5Z)-7-Oxozeaenol is a resorcyclic lactone of fungal origin that acts as a potent and selective transforming growth factor-β-activated kinase 1 (TAK1) mitogen-activated protein kinase kinase kinase (MAPKKK) inhibitor (IC50 = 8 nM). Displays > 33-fold and > 62-fold selectivity over MEKK1 and MEKK4 respectively. Inhibits IL-1-induced activation of NF-κB (IC50 = 83 nM) and JNK/p38. Inhibits production of inflammatory mediators, and sensitizes cells to TRAIL- and TNF-α-induced apoptosis in vitro.

Works great for kinase assay. This was tested in TAK1 in vitro kinase assay.
Primary human small airway epithelial cells were incubated with TAK1 inhibitor prior to the addition of poly(I:C). The supernatant was collected and analyzed for IL-6.
