Biological Activity for GSK 126

GSK 126 is a very high affinity and selective EZH2 inhibitor (Ki = 0.5 - 3 nM). Exhibits >150-fold selectivity for EZH2 over EZH1 and >1000-fold selectivity over 20 other human methyltransferases. Inhibits proliferation of B-cell lymphoma cell lines in vitro. Also inhibits H3K27Me3 and tumor growth in mice bearing BCL xenografts. Targeting p53 and histone methyltransferases restores exhausted CD8+ T cells in HCV infection. Promotes the transition of ESCs to feeder-free extended pluripotent stem (EPS) cells in combination with LCDM cocktail.
