| 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[1].
|
| 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)[1].

| Animal Admin |
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[1].
