Catalog Number: 4904
Chemical Name: N-[(1,2-Dihydro-6-methyl-2-oxo-4-propyl-3-pyridinyl)methyl]-1-(1-methylethyl)-6-[6-[4-(1-methylethyl)-1-piperazinyl]-3-pyridinyl]-1H-indazole-4-carboxamide
Biological Activity
Potent and SAM-competitive EZH2/EZH1 lysine methyltransferase inhibitor (IC50 values are 2 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.
