Zeaenol

LL Z1640-4 is a cis-enol resorcylic acid lactone first reported in 1978 exhibiting both antiviral and antiprotozoan activity. More recently, LL Z1640-2, containing the essential cis-enone system that selectively inhibits TAK 1, has gained literature focus. With its "inactive" cis-enol, LL Z1640-4 is an ideal negative control to help dissect the selectivity of the MAP kinases.

A cell-permeable resorcylic acid lactone compound that may serve as a negative control for TAK1 (TGF-β-Activated Kinase-1) inhibition studies. The active TAK1 inhibitor is also available, (5Z)-7-Oxozeaenol, Curvularia sp. (Cat. No. 499610).
