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.
This probe is supplied in conjunction with the Structural Genomics Consortium. For further characterization details, please visit the SGC 0946 probe summary on the SGC website.
