UNC1999 is an orally active, highly selective inhibitor of both wild-type and mutant EZH1 and EZH2 lysine methyltransferases (IC50 = 45 nM and 2 nM respectively)(ref 1). Inhibition of EZH2 with UNC1999 enhanced the efficacy of gefitinib in suppressing the proliferation of colon cancer cells (ref 2). It suppresses global H3K27 trimethylation/demethylation and inhibits the growth of mixed lineage leukemia (MLL)-rearranged leukemia cells (ref 3).


White powder. May be dissolved in DMSO (10 mg/ml).
