Bioactivity

• Target IC50:
  DOT1L:0.4 nM
• In Vivo:
  After inhibition of DOT1L, EPZ004777 selectively inhibited the proliferation of MLL-rearranged cell lines and MLL-AF9-transformed murine hematopoietic cells.EPZ004777 also induced differentiation and apoptosis in MLL-rearranged cell lines. EPZ004777 selectively inhibited cellular H3K79 methylation and suppressed the expression of key MLL fusion target genes.EPZ004777 selectively inhibited the proliferation of hematopoietic cells in mice transformed with MLL-AF10 and CalM-AF10.EPZ004777 inhibition of DOT1L resulted in a significant decrease in the proliferation of hematopoietic cells in mice transformed with MLL-AF6. MLL-AF6 target gene expression was reduced and cell cycle arrest was observed.

• Cell Research:
  For assessment of cell proliferation and viability in human cell lines, exponentially growing cells are plated, in triplicate, in 96-well plates in a nal volume of 150 ml. Cells are incubated in the presence of 3 μM (proliferation curve), or increasing concentrations (IC50 determination) of EPZ004777 up to 50 μM. Viable cell number is determined every 3–4 days for up to 18 days using the Guava Viacount assay and analyzed on a Guava EasyCyte Plus instrument according to the manufacturer’s protocol. On days of cell counts, growth media and EPZ004777 are replaced and cells split back to a density of 5×104 cells/well. Total cell number is expressed as split-adjusted viable cells per well. For each cell line, IC50 values are determined from concentration-dependence curves at each time point using Graphpad Prism software. Experiments to determine IC50 values continues until IC50 values stabilized (day 18 for THP-1 cells, day 14 for all other cell lines). For assessment of the effect of EPZ004777 treatment on transformed murine hematopoietic progenitors, cells from two independent transductions for each virus are plated in 24-well plates at a density of 0.5–1×105 cell/well in 1 ml media in 24-well plates and exposed to increasing concentrations of EPZ004777 up to 30 mM. Cells are counted and replated at equal cell numbers in fresh media with fresh compound every 3–4 days. For MTT assays, cells from serial replatings are harvested on day 10 and plated, in triplicate at 2×104 cells/well in 100 ml media with the appropriate concentration of EPZ004777. Cells are incubated for 2.5 days, the exposed to 10 ml MTT reagent for 3 hr, and lysed over night in 100 ml MTT- solubilization buffer (both from Cell Proliferation Kit I [MTT]).
