CM-272 is a first-in-class, potent, selective, substrate-competitive and reversible dual G9a/DNA methyltransferases (DNMTs) inhibitor with antitumor activities. CM-272 inhibits G9a, DNMT1, DNMT3A, DNMT3B and GLP with IC50s of 8 nM, 382 nM, 85 nM, 1200 nM and 2 nM, respectively. CM-272 inhibits cell proliferation and promotes apoptosis, inducing IFN-stimulated genes and immunogenic cell death.

CM-272 (100-1000 nM; 12-72 hours; CEMO-1, MV4-11 and OCI-Ly10 cell lines) treatment inhibits cell proliferation in a dose- and time-dependent manner.
CM-272 (100-1000 nM; 24 hours; CEMO-1, MV4-11 and OCI-Ly10 cell lines) treatment blocks cell cycle progression.
CM-272 (100-1000 nM; 12-72 hours; CEMO-1, MV4-11 and OCI-Ly10 cell lines) treatment induces apoptosis in ALL, AML and DLBCL cell lines in a dose- and time-dependent manner.
CM-272 after 48 h of treatment CEMO-1 acute lymphoblastic leukaemia (ALL) cell line, MV4-11 acute myeloid leukaemia (AML) cell line and OCI-Ly10 diffuse large B-cell lymphoma (DLBCL) cell line, the GI50 values of 218 nM, 269 nM and 455 nM, respectively, and is associated with a decrease in global levels of H3K9me2 and 5mC.
The therapeutic activity of CM-272 relies on the early activation of the type I IFN response in tumour cells, potentially leading to the induction of cell autonomous immunogenic death in tumour cells.
