GO289

GO289 (GO-289, GO 289) is a potent and selective inhibitor of casein kinase 2 (CK2) with IC50 of 7 nM in in vitro kinase assays, shows minor effects on CKIδ and CKIα activity in vitro; GO289 showed only a moderate or minor effect on the activity of 59 kinases from a variety of classes, the second most affected kinase was PIM2 with an IC50 of 13 nM; caused dose-dependent lengthening of circadian period not only in Bmal1-dLuc reporter cells but also in Per2-dLuc reporter cells with a phase opposite to that of Bmal1-dLuc, inhibits phosphorylation of clock protein PER2 S693 in cells; strongly inhibits Caki-2, A498, and 769-P cancer cells, significantly reduces growth of mouse MLL-AF9 leukemia cells without effect on hematopoietic progenitor cells; shows effectivity on circadian period and reporter signal intensity in spleen explants of MLL-AF9 mice.
