Proposed binding site in the SET domain of EZH2. (A) Close view on the pyridone moiety of compound 5 from its docked pose in human PRC2 complex. Substitution at 4-position of the pyridone ring allows the compound to make more van der Waals contacts with F665, R685 and F686. (B) Close view on the pyridone moiety of compound 31 from its docked pose in human PRC2 complex. White surface, EZH2 binding pocket; purple, van der Waals surface of the ligand.
