Biochem/physiol Actions

The polycomb repressive complex 2 (PRC2), which represses gene expression through methylation of histone H3 on lysine 27 (H3K27), contains either EZH1 or EZH2 as its catalytic subunit, with EZH1 being found in both dividing and non-dividing cells, whereas EZH2 is only found in actively dividing cells. UNC1999 is an orally bioavaliable selective inhibitor of both EZH2 and EZH1 lysine methyltransferases with IC50 < 10 nM for EZH2 and 45 nM for EZH1. UNC1999 potently inhibited both wild-type and mutant Y641N EZH2 methyltransferase activity with less than a 5-fold difference in potency, and selectively killed diffused large B cell lymphoma (DLBCL) cells bearing Y641 point mutations. It was selective for EZH2 and EZH1 over 15 other lysine, arginine and DNA methyltransferases. UNC1999 is competitive with the cofactor S-adenosylmethionine (SAM) and non-competitive with the peptide substrate. Because it inhibits both EZH2 and EZH1, UNC1999 has potential advantages over EZH2 selective inhibitors in the disease settings where both PRC2 – EZH2 and PRC2 – EZH1 contribute to the methylation of H3K27.
