    EZH2, Ki:24 nM
描述 EZH2 is the enzymatically active core subunit of the PRC2 complex, which methylates H3K27 and facilitates chromatin compaction and gene silencing. EPZ005687 is a potent inhibitor of PRC2 with IC50 value of 54±5nM (measured by PRC2 enzymatic activity), with selectivity >500-fold over other HMTs, ~50-fold over EZH1. EPZ005687 can specifically inhibit H3K27 methylation. Treatment with EPZ005687 (0.044-5.6uM) for 96h shows a dose-dependent decrease in H3K27me3 in wild-type EZH2 lymphoma cell line OCI-lY19. EPZ005687 can decrease proliferation in a dose (<8.3uM) and time (<11 days) dependent manner in mutant EZH2 lymphoma cells, WSU-DLCL2 (Y641F) and pfeiffer (A677G), but not wild-type cells, OCI-lY19 cell line. Treatment in mutant EZH2 lymphoma cells, WSU-DLCL2 (Y641F), with EPZ005687 (0.2-6uM) for 4 days resulted in a dose-dependent increase of accumulation in G1[1]. Recently, it was found that EPZ005687 (10mg/kg, injected peritoneally, once a week for 4 weeks) can significantly inhibit the development of TAC (Transverse Aortic Constriction) -induced PAH (pulmonary artery hypertension) in an EZH2-SOD1-ROS dependent manner in male balb/c mice (6–8 weeks old) [2].
作用机制 EPZ005687 is a SAM-competitive inhibitor of PRC2, which binds in the SAM pocket of the EZH2 SET domain.[1]
