General description

A cell-permeable benzamide compound that acts as a non-competitive, highly potent, selective MEK/MAPKK/MKK inhibitor and effectively blocks cellular Erk1/2 phosphorylation (by >90% in serum-starved HeLa after serum-stimulation and 50% in C26 with 25 and 0.33 nM inhibitor, respectively), while exhibiting little or no effect against the activity of Erk1/2 or a panel of 66 other kinases even at concentrations as high as 10 µM in cell-free kinase assays. Shown to be orally available in mice and suppress both the growth of and Erk phosphorylation in BRAF(V600E)-expressing SKMEL28 cell-derived tumor in vivo.

The Polycomb repressive complex 2 (PRC2) is an essential epigenetic regulator that deposits repressive H3K27me3. PRC2 subunits form two holocomplexes-PRC2.1 and PRC2.2-but the roles of these two PRC2 assemblies during differentiation are unclear. We employed auxin-inducible degradation to deplete PRC2.1
