A-395 associates tightly to EED in a 1:1 binding model with a KD value of 1.5 nM (shown by SPR). A-395 inhibits the trimeric PRC2 complex (EZH2–EED–SUZ12) with an IC50 of 18 nM using a radioactivity-based...

This compound closely phenocopies EZH2 enzyme inhibitors, which are better-characterized and have greater in vivo utility. Therefore, this would be an alternative choice for EZH2 inhibitor-resistant...
