    Product Description

    CPI-1205 is a potent and orally bioavailable inhibitor of the lysine methyltransferase EZH2 (IC50s = 2 and 3 nM for wild-type and the constitutively active EZH2 Y641N catalytic mutant, respectively).1 It is selective for EZH2 over a panel of 30 histone and DNA methyltransferases and 54 receptors, transporters, and ion channels at a concentration of 10 μM. However, CPI-1205 does inhibit EZH1 (IC50 = 52 nM). CPI-1205 decreases levels of H2K27me3 in HeLa cells (EC50 = 32 nM). In vivo, CPI-1205 (160 mg/kg) reduces tumor size and H3K27me3 levels in a KARPAS-422 B cell lymphoma xenograft mouse model.
