SynonymsH3K27 Methylation Inhibitor, SAH-EZH2, EED-EZH2 Protein-Protein Interaction Inhibitor, SAH-EZH2, Enhancer of Zested Homolog 2 Inhibitor III, HMTase Inhibitor XIV
DescriptionA stabilized a-helical 27-mer peptide (FSSNRXKILXRTQILNQEWKQRRIQPV) with E54Q modification that exhibits robust cellular uptake and nuclear localization and directly binds to embryonic ectoderm development (EED; Kd = 320 nM) and disrupts protein-protein interaction of EED with EZH2 ( Enhancer of zeste homolog 2 ) and EZH1. Selectively inhibits methyltransferase activity of the Polycomb repressive complex 2 (PRC2) and reduces H3K27 methylation in a dose-dependent manner (~1 to 10 µM). Induces growth arrest at the Go/G1 phase (after 6 days of treatment) and monocyte-macrophage differentiation in MLL-AF9 leukemia cells without inducing any apoptosis. Growth arrest is suggested to be associated with an increase in p19ARF levels. Shown to block the proliferation of C1498 and M1 myeloid leukemia cells without affecting non-tumorigenic HPC5 cells.
