Quercetagetin

Quercetagetin is a cell-permeable flavanol compound that acts a potent, ATP-competitive, and reversible inhibitor of PIM1 kinase (IC50 = 340 nM). Exhibits ≥7-fold selectivity over 8 other kinases tested, including PIM2 (IC50 = 3.45 µM), and little activity toward c-Abl even at concentrations as high as 200 µM. Inhibits cellular BAD phosphorylation (IC50 = 5.5 µM) and induces growth arrest (ED50 = 3.8 µM) in PIM1-expressing RWPE2 cells.
