Biological Activity

Description EBI-2511 is a highly potent and orally active EZH2 inhibitor with an IC50 of 4 nM for EZH2(A667G).
EZH2(A667G) [1]
(Cell-free assay)
4 nM
In vivo

In in vivo experiments, rats are administrated with dosages of 5 mg/kg EBI-2511 (p.o.) and 0.5 mg/kg EBI-2511 (i.v.). Mice are administrated with dosages of 10 mg/kg p.o. and 1.0 mg/kg i.v. For i.v. administration, the clearance of EBI-2511 is modest with CLz/F of 26 and 32 mL/min/kg in rats and mice, respectively. After a single 5 and 10 mg/kg oral dose of a CMC-Na suspension of EBI-2511 to rats and mice, its AUC0‑t reaches 239 and 774 ng/mL·h with oral bioavailability of 9% and 16%, respectively. plasma protein binding of EBI-2511 in human, rat, and mouse are 93.9%, 94.0%, and 92.7%, respectively[1].

Protocol (from reference)

Cell Research:


  • Cell lines: Pfeiffer cells
  • Concentrations: --
  • Incubation Time: 5 days
  • Method:

    Cells are seeded in 96 well plates at a density of 1,000 to 8,000 cells per well and cultured overnight at 37 ℃ incubator in medium supplemented with 10% FBS. On the next day, the test compounds at various concentrations or vehicle control (0.5% DMSO) are added into cell culture. After 5 day treatment, the growth of cells is evaluated.

Animal Research:


  • Animal Models: Sprague Dawley rats and ICR mice
  • Dosages: In rats: 5 mg/kg (p.o.), 0.5 mg/kg (i.v.); In mice, 10 mg/kg (p.o.), 1 mg/kg (i.v.)
  • Administration: i.v. or p.o.

Working concentration: mg/ml;

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.
