| In Vitro | In vitro activity: 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. Kinase Assay: The enzyme inhibition constant (Ki) value for EPZ5676 was determined by fitting inhibition data to the Morrison quadratic equation. Residence time for EPZ5676 was calculated as the reciprocal of the enzymatic-ligand dissociation rate, determined by surface plasmon resonance. Cell Assay: EPZ5676 potently inhibited MV4-11 cell proliferation with an IC50 value of 3.5 nM. Antiproliferative activity was realized after 4 days and was most clear after 7 days of EPZ-5676 treatment. |
