(2E)-5-[3-(Phenylsulfonylamino)phenyl]pent-2-en-4-ynohydroxamic Acid Solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. A cell-permeable, aromatic sulfonamide derivative with a hydroxamic acid group that potently inhibits mammalian histone deacetylase (IC50 = 15.7 nM) by binding to the active site Zinc. Augmented the expression of transcription factor JunD and causes an inhibition of transformation in K-ras-transformed NIH3T3 cells (MIC ~40 nM). Upregulates plasminogen activator inhibitor type 2 (PAI-2) expression with concomitant inhibition of urokinase (u-PA) gene and protein expression in HT-1080 and U-937 cells. Elevates the expression of extracellular matrix proteins fibronectin and gelsolin. Purity: ≥95% by HPLC. Ref.: Lavoie, R., et al. 2001. Bioorg. Med. Chem. Lett. 11, 2847.
