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

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.

Technical Data

Soluble to 25 mM in DMSO and to 10 mM in ethanol
>99 %
Desiccate at -20°C
