Description

A cell permeable diketone analog of curcumin that acts as a specific inhibitor of JAK2 (~ 5 µ,M) and blocks STAT3 phosphorylation in MDA-MB-231 breast and PANC-1 pancreatic cancer cells. However, it does not affect STAT3 phosphorylation in normal human mammary epithelial cells or human pancreatic duct epithelial cells. Does not block the activity of tyrosine kinases containing SH2 and SH2-SH3 domains and several other kinases, such as Akt2, Cdk2-cyclin D1, EGFR kinase, Met, and EbrB2/Her2 kinase (IC50 >100 µ,M). Also shown to block DNA binding activity of STAT3. Significantly reduces the viability and invasion capacity of various cancer cells (IC50 = 640 nM, 110 nM, 140 nM, 600 nM, 400 nM in PANC-1, HPAC, MDA-MB-231, SK-BR3, and SUM-159 cells, respectively) and induces apoptosis. Shown to significantly reduce tumor burdens in the MDA-MB-231 xenografted mice., A cell permeable diketone analog of curcumin that acts as a specific inhibitor of JAK2 (~ 5 µ,M) and blocks STAT3 phosphorylation in MDA-MB-231 breast and PANC-1 pancreatic cancer cells.
