EED226 induces a conformational change upon binding EED, leading to loss of PRC2 activity. This compound also effectively inhibits PRC2 containing a mutant EZH2 protein resistant to SAM-competitive inhibitors. It regulates histone H3K27 methylation and PRC2 target gene expression in cells. In the in vitro enzymatic assays, this chemical inhibits PRC2 with an IC50 (half-maximal inhibitory concentration) of 23.4 nM when the H3K27me0 peptide is used as substrate and 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). It is noncompetitive with both SAM and peptide substrate. This compound bound to EED and PRC2 complex with a 1:1 stoichiometry and Kd of 82 nM and 114 nM, respectively. It does not disrupt the PRC2 complex and could still occupy its binding pocket with a SAM-competitive EZH2 inhibitor bound to PRC2. This chemical shows remarkable selectivity for PRC2 complex over 21 other protein methyltransferases, kinases and other protein classes, The only other histone methyltransferase that can be inhibited by it is the EZH1-PRC2 complex. It with moderate permeability leads to a dose-dependent decrease of both global H3K27me3 and H3K27me2 markers in G401 cell.

| In vivo |
This compound effectively induces tumor regression in a mouse xenograft model. It in a solid dispersion formulation are well tolerated in animals. This chemical clearly demonstrates a dose-dependent efficacy in the mouse xenograph study. It inhibits the growth of diffuse large B-cell lymphoma (DLBCL) xenografts and reduces H3K27me3 levels to a similar extent as an EZH2 inhibitor. It has very low in vivo and in vitro clearance and approximately 100% oral bioavailability, low volume of distribution (0.8 L/kg), reasonable terminal t1/2 (2.2 h), and moderate plasma protein binding (PPB)(14.4%). Its solubility is relatively low and with little dependency on the pH of the medium.
