Description
InformationCM272 CM-272 is a novel first-in-class dual reversible inhibitor of G9a (GLP) and DNMTs with IC50 of 8 nM, 382 nM, 85 nM, 1200 nM, 2 nM for G9a, DNMT1, DNMT3A, DNMT3B, GLP, respectively. CM-272 prolongs survival in in vivo models of haematological malignancies by at least in part inducing immunogenic cell death.TargetsG9a (Cell-free assay); DNMT3A (Cell-free assay); DNMT1 (Cell-free assay); DNMT3B (Cell-free assay) 8 nM ;85 nM; 382 nM; 1200 nMIn vitroThe GI50 for CM-272 after 48\u2009h of treatment in ALL, AML and DLBCL-derived cell lines is in the nM range and is associated with a decrease in global levels of H3K9me2 and 5mC. CM-272 inhibits cell proliferation, blocks cell cycle progression and induces apoptosis in ALL, AML and DLBCL cell lines in a dose-dependent manner. CM-272 induces IFN response and immunogenic cell death. In vivoCM272 therapy induces a statistically significant increase in overall survival (OS) in mice in comparison with control animals. Global H3K9me2 and 5mC levels are reduced in leukaemic cells obtained from mice engrafted with ALL-derived CEMO-1 cells after 1\u2009week of treatment and no significant weight loss is observed in treated animals. CM272 shows dose-dependent efficacy and a dose of 2.5\u2009mg/kg of CM272 is adequate to demonstrate the positive anti-tumour efficacy in mice engrafted with ALL-derived CEMO-1 cells.
