Biological Activity

Description EPZ011989 is a potent, selective, orally bioavailable EZH2 inhibitor with Ki of <3 nM.
EZH2 [1]
(Cell-free assay)
EZH1 [1]
(Cell-free assay)
<3 nM(Ki) 103 nM
In vitro

EPZ011989 equipotently inhibits mutant and wild-type EZH2 with an inhibition constant (Ki) of <3 nM. EPZ011989 is also a specific EZH2 inhibitor with a >15-fold selectivity over EZH1 and >3000-fold selectivity relative to the Ki of 20 other histone methyltransferases (HMTs) tested. As evidenced by the human and rat liver microsomal turnover, EPZ011989 also exhibits metabolic stability. EPZ011989 reduces cellular H3K27 methylation in the Y641F, mutant-bearing human lymphoma cell line, WSU-DLCL2, with an IC50 below 100 nM[1]. EPZ011989 inhibits H3K27me3 in wild-type EZH2 AML cell lines (Kasumi-1, MOLM-13, and MV4-11) at a concentration of 0.625 μM after only four days of treatment. At these concentrations and this time point, no change in viability among these three cell lines is observed and only minimal proliferation inhibition in MV4-11 and MOLM-13 cells[2].

In vivo EPZ011989 demonstrates significant tumor growth inhibition in a mouse xenograft model of human B cell lymphoma. EPZ011989 is able to elicit robust methyl mark inhibition and antitumor activity[1].

Protocol (from reference)

Cell Research:


  • Cell lines: WSU-DLCL2 cells
  • Concentrations: 0-10 μM
  • Incubation Time: 0-11 days
  • Method:

    For assessment of cell proliferation and viability, exponentially growing cells are plated, in triplicate, in 96-well plates. Cells are incubated with increasing concentrations of EPZ011989. Viable cell number is determined every 3-4 days for up to 11 days using the Guava Viacount assay.

Animal Research:


  • Animal Models: SCID mice
  • Dosages: 250 and 500 mg/kg
  • Administration: p.o.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
