THP-1 cells were treated with MI-3 (6.25 μM, 6 days), GSK126 (5 μM, 6 days), or EPZ004777 (5 μM, 6 days), with orwithout PMA (50 ng/mL, 12 h), and surface expression of CD11b was determined by ﬂow cytometric analysis. The data are representedas the mean ± SD, n = 3. THP-1 cells were collected for Wright-Giemsa staining.

|Description||EPZ004777 is a potent, selective DOT1L inhibitor with IC50 of 0.4 nM in a cell-free assay and demonstrates >1,200-fold selectivity for DOT1L over all other tested PMTs.|
EPZ004777 selectively inhibits cellular H3K79 methylation and inhibits expression of key MLL fusion target genes. Following DOT1L inhibition, EPZ004777 selectively inhibits proliferation of MLL-Rearranged cell lines and MLL-AF9-transformed murine hematopoietic cells. In addition, EPZ004777 also induces differentiation and apoptosis in MLL-rearranged cells.  EPZ004777 selectively inhibits proliferation of MLL–AF10 and CALM–AF10-transformed murine bone marrow cells.  DOT1L inhibition by EPZ004777 results in significantly decreased proliferation, decreased expression of MLL-AF6 target genes, and cell cycle arrest of MLL-AF6-transformed cells. 
|In vivo||EPZ004777 produces potent antitumor efficacy, and significantly increases median survival in a mouse xenograft model of MLL leukemia. |
Determination of Inhibitor IC50 Values:EPZ004777 is serially diluted 3-fold in DMSO for a total of ten concentrations, beginning at 1 mM. A 1 μL aliquot of each inhibitor dilution is plated in a 384-well microtiter plate. The 100% inhibition control consisted of 2.5 mM ﬁnal concentration of the product inhibitor S-adenosyl-L-homocysteine, (SAH). Compound is incubated for 30 min with 40 ml per well of 0.25 nM DOT1L(1-416) in assay buffer (20 mM TRIS [pH 8.0] 10 mM NaCl, 0.002% Tween 20, 0.005% Bovine Skin Gelatin, 100 mM KCl, and 0.5 mM DTT). 10 ml per well of substrate mix comprising assay buffer with 200 nM 3H-SAM (American Radiolabeled Chemicals: 80 Ci/mmol), 600 nM unlabeled SAM, and 20 nM nucleosomes are added to initiate the reaction (both substrates are present in the ﬁnal reaction mixture at their respective KM values). Reactions are incubated for 120 min and quenched with 10 ml per well of 800 mM SAM. Incorporation of radioactivity into nucleosome substrate is measured in a ﬂashplate. IC50 values for enzymes in the histone methyltransferase panel are determined under similar balanced assay conditions with both SAM and protein/peptide substrate present at concentrations equal to their respective KM values.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
