Beschreibung

Allgemeine Beschreibung

Ezh2 Inhibitor III, SAH-EZH2 is a stabilizeda-helical 27-mer peptide (FSSNRXKILXRTQILNQEWKQRRIQPV )with E54Q modification. It shows strong cellular uptake and nuclearlocalization and directly forms a complex during embryonic ectodermdevelopment. It blocks the protein-protein interaction of embryonic ectoderm development(EED) with enhancer of zeste homolog (EZH) 1 and 2. Selectively inhibits methyltransferase activity of the Polycombrepressive complex 2 (PRC2) and reduces H3K27 methylation in a dose-dependentmanner (~1 to 10 µM). This inhibitor induces growth arrest after six days oftreatment at the G0/G1 phase and monocyte-macrophage differentiation in MLL-AF9leukemia cells without inducing any apoptosis. The growth arrest is suggestedto be associated with an increase in p19ARF levels. It blocks the proliferationof M1 myeloid leukemia cells and C1498 without having any effect onthe non-tumorigenic HPC5 cells.
