EED226 is a polycomb repressive complex 2 (PRC2) inhibitor, which binds to the K27me3-pocket on embryonic ectoderm development (EED) and shows strong antitumor activity in xenograft mice model[1]. EED226 is a potent, selective, and orally bioavailable EED inhibitor[2]. EED226 inhibits PRC2 with an IC50 of 23.4 nM when the H3K27me0 peptide is used as a substrate in the in vitro enzymatic assays[3].
IC50 & Target
IC50: 23.4 nM (PRC2)[3]
In Vitro
EED226 is a highly potent, efficient and selective inhibitor of EZH2 and EZH1 evaluated against a broad range of epigenetic and non-epigenetic targets. It potently reduces global H3K27Me3 mark in cells and demonstrates selectively cell killing effects in cells carrying a heterozygous Y641N mutation. EED226 has moderate permeability as the measured in Caco-2 cells at A→B=3.0x10-6 cm/s, with an efflux ratio at 7.6[2]. In the in vitro enzymatic assays, EED226 inhibited PRC2 with an IC50 of 53.5 nM when the mononucleosome is used as the substrate, with the stimulatory H3K27me3 added at 1× Kact (1.0 μM)[3].

In Vivo
EED226 induces robust and sustained tumor regression in EZH2MUT pre-clinical DLBCL model. In CD-1 mice, dosing of EED226 for 14 days at 300 mg/kg bid is well tolerated with no apparent adverse effects. It has very low in vivo clearance, and approximately 100% oral bioavailability. EED226 has low volume of distribution (0.8 L/kg), reasonable terminal t1/2 (2.2 h), and moderate plasma protein binding (PPB)[2].

*Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles. Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Protocol 1
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.77 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3
Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (6.77 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

For the following dissolution methods, please prepare the working solution directly.
It is recommended to prepare fresh solutions and use them promptly within a short period of time. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution.
If precipitation or phase separation occurs during preparation,
heat and/or sonication can be used to aid dissolution.

Administraciòn de animales
[2]
Mice: EED226 is formulated as a suspension in 0.5% PHMC+0.5% Tween 80 in water and administered orally by gavage at a dose volume of 10 mL/kg to the tumor bearing mice. At the end point, the animals is given the first dose administration. For PK analysis 100 μL of blood samples are collected from each animal by orbital sinus bleeding. For analysis of compound levels and PD in tissues, tumors are collected 4 hr post treatment and frozen immediately in liquid nitrogen. Tumor and body weight change data are analyzed statistically[2].

Help & FAQs
Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
