BIX 01294

BIX-01294 is a G9a-like protein and G9a histone lysine methyltransferase inhibitor with IC50 values of 0.7 and 1.7 μM respectively. BIX-01294 inhibits the G9aHMTase dependent levels of histone-3 lysine (9) methylation (H3K9me). BIX-01294 can also inhibit H3K9 Jumonji demethylase KIAA1718 with half-maximal inhibitory concentrations in low micromolar range. In its inhibition of the histone lysine methyltransferases, BIX 01294 does not compete with cofactor S-adenosyl-methionine. The target enzyme is G9a, and it selectively impairs G9a HMTase and the generation of H3K9me2 in vitro. BIX-01294 (4.1 μM) reduces H3K9me2 Levels in bulk histone preparations from wt ES cells, mouse embryonic fibroblasts and HeLa cells. BIX-01294 reduces H3K9me2 at Several G9a Target Genes including Bim1 and Serac1.
