DNMT-IN-6
DNMT-IN-6 is a DNA methyltransferase inhibitor with activity against DNMT1, DNMT3A, and DNMT3B. DNMT-IN-6 drives demethylation, and restores TMS1 tumor suppressor gene expression. DNMT-IN-6 induces apoptosis, causes G2/M phase arrest, disrupts mitochondrial integrity, and activates the intrinsic caspase cascade (3/7/9). DNMT-IN-6 inhibits tumor growth, and improves survival in xenograft models. DNMT-IN-6 can be used for the research of cancer, such as diffuse large B-cell lymphoma.

In Vitro
DNMT-IN-6 (Compound CZ2) (0.2-1.4 μM; 24-48 h) potently inhibits proliferation of SUDHL-4, SUDHL-6, and DB DLBCL cell lines in a dose- and time-dependent manner, with 24 h IC50 values of 0.67 μM, 0.72 μM, and ~0.90 μM respectively, and exhibits minimal cytotoxicity to normal HK-2 and MIN-6 cells[1].
DNMT-IN-6 (1 μM; 24 h) induces mitochondrial membrane depolarization in SUDHL-4 and SUDHL-6 DLBCL cells[1].
DNMT-IN-6 (1 μM; 24 h) significantly induces apoptosis in SUDHL-4 and SUDHL-6 DLBCL cells, and activates caspase-3 and caspase-9[1].
DNMT-IN-6 (1 μM; 24 h) reduces intracellular ATP levels in SUDHL-4 and SUDHL-6 DLBCL cells[1].
DNMT-IN-6 (1 μM; 24 h) induces G2/M cell cycle arrest in SUDHL-6 DLBCL cells[1].
DNMT-IN-6 (1 μM; 24 h) reduces TMS1 promoter methylation, increases TMS1 expression, and decreases DNMT1, DNMT3A, and DNMT3B expression in SUDHL-4 and SUDHL-6 DLBCL cells[1].
DNMT-IN-6 (1 μM; 24 h) inhibits the binding of DNMT3A to the TMS1 promoter in SUDHL-4 DLBCL cells, contributing to TMS1 promoter demethylation[1].
