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.
This probe is supplied in conjunction with the Structural Genomics Consortium. For further characterization details, please visit the UNC 1999 probe summary on the SGC website.

Cancer Metabolism Poster
Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the main targets for cancer metabolism researchers. Genetic changes and epigenetic modifications in cancer cells alter the regulation of cellular metabolic pathways. These distinct metabolic circuits could provide viable cancer therapeutic targets.
Epigenetics in Cancer Poster
Adapted from the 2015 Cancer Product Guide Edition 3, this poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.
