Biological Activity for UNC 1999

UNC 1999 is a potent and SAM-competitive EZH2/EZH1 lysine methyltransferase inhibitor (IC₅₀ values are 10 and 45 nM, respectively). Selective for EZH2/EZH1 over a panel of other methyltransferases and non-epigenetic targets. Reduces H3K27me3 levels in vitro. Prolongs survival of MLL-AF9 bearing mice. Orally bioavailable.

Negative Control also available.
