용도Hypothemycin is a potent and selective inhibitor of threonine/tyrosine-specific kinase, MEK, and other protein kinases that contain a conserved cysteine residue in the ATP-binding site in in vitro studies.

일반 설명A cell-permeable cis-enone resorlic acid lactone (RAL) and (5Z)-7-Oxozeaenol (Cat. No. 499610) analog that inhibits several kinases via an initial affinity binding to the ATP pocket, followed by a covalent adduct formation with a conserved ATP site cysteine residue of the targeted enzymes, including, but not limited to, Flt1/VEGFR-1, Flt3, cKit(D816V), MAPK1, MAPK2, MEK1, MKK6, PKCμ, PKD2, PRAK, and Tak1 (≥90% inhibition at 2 μM). Hypothemycin is also reported to inhibit two non-RAL targets (99% and 82% inhibition of TrkA and TrkB, respectively, at 2 μM), while one of the 46 putative cis-enone RALs targets, namely GSK-3α, is shown not to be affected. Hypothemycin inhibits multiple kinases involved in MAP kinase pathways and is therefore particularly effective in inhibiting BRAF(V600E)-dependent tumor growth. (5Z)-Zeaenol (Cat. No. 499609) may serve as a negative control.
