Product Description:

EPZ-5676 is an S-adenosyl methionine (SAM) competitive inhibitor of protein methyltransferase DOT1L with Ki of 80 pM in a cell-free assay, demonstrating >37,000-fold selectivity against all other PMTs tested, inhibits H3K79 methylation in tumor. Phase 1.


In vitro :

EPZ-5676 reduces H3K79 dimethylation with a cellular IC50 of 2.6 nM in MV4-11 cells. EPZ-5676 treatment results in concentration- and time-dependent reduction of H3K79 methylation without effect on the methylation status of other histone sites, which leads to inhibition of key MLL target genes and selective, apoptotic cell killing in MLL-rearranged leukemia cells. EPZ-5676 inhibits proliferation of MLL-AF4 rearranged cell line MV4-11 with an IC50 of 9 nM.


In vivo :

EPZ-5676 continuously intravenous infusion for 21 days to xenograft model of MLL-rearranged leukemia, leads to dose-dependent anti-tumor activity. At the highest dose of 70.5 mg/kg/day, complete tumor regressions are achieved with no regrowth for up to 32 days after the cessation of treatment. No significant weight loss or obvious toxicity is observed in rats treated with EPZ-5676 during efficacy study.
