A cell-permeable dihydropyridopyrimidine-carboxamide compound that acts as a potent and reversible inhibitor of Mirk/Dyrk1B and Dyrk1A kinases (IC50 = 68 and 22nM). Exhibits very high selectivity for Mirk/Dyrk1B compared to Abl, Flt3, and MARK1 (64, 56 and 73% inhibition at 10uM, respectively) and a panel of 46 other kinases. Shown to induce activation of caspase-3 and sensitize tumor cells to the action of gemcitabine and cisplatin, possibly by de-stabilizing p27. Preferentially increases cycling in Mirk-elevated quiescent pancreatic cancer cells (SU86.86, Panc1, AsPc1, and SW620 at ~1uM). Also, shown to increase level of superoxides in quiescent pancreatic tumor cells (Panc1, SU86.86, and AsPc1) by blocking SOD2 and SOD3 activities.
