Catalog Number: 4541
Chemical Name: 1-[3-[[[(2R,3S,4R,5R)-5-(4-Amino-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl](isopropyl)amino]propyl]-3-[4-(2,2-dimethylethyl)phenyl]urea
Biological Activity
Highly potent DOT1L methyltransferase inhibitor (Kd = 0.06 nM, IC50 = 0.3 nM in a radioactive assay); blocks H3K79 methylation in A431 cells and MCF10A cells. Inactive at 12 histone methyltransferases and DNMT1. Selectively kills cells transformed with the MLL-AF9 fusion oncogene in an in vitro model of leukemia; lowers levels of MLL target genes HOXA9 and Meis1.
