MedKoo CAT#: 407490

CAS#: 2089148-72-9 (free base)

Description: A-395 is a potent and selective EED inhibitor. A-395 includes potent binding to EED with Ki = 0.4 nM, inhibits the PRC2 complex with IC50 = 34 nM for methylation of H3K27 and greater than 100-fold selectivity over other histone methyltransferases and non-epigenetic targets. In cellular assays, A-395 inhibits the PRC2 complex (thus inhibiting the formation of H3K27me3) with IC50 = 90 nM (RD rhabdoid tumor cell line; 3 days). A-395 represents a first-in-class antagonist of PRC2 protein-protein interactions (PPI) for use as a chemical probe to investigate the roles of EED-containing protein complexes.
