生物活性

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[1].

DNMT-IN-6 (1 μM; 24 h) 可降低 TMS1 启动子甲基化水平,上调 TMS1 的表达,并下调 SUDHL-4 和 SUDHL-6 弥漫性大 B 细胞淋巴瘤 (DLBCL) 细胞中 DNMT1、DNMT3A 及 DNMT3B 的表达[1]
DNMT-IN-6 (1 μM; 24 h) 可抑制 DNMT3A 与 SUDHL-4 弥漫性大 B 细胞淋巴瘤 (DLBCL) 细胞中 TMS1 启动子的结合,进而促进 TMS1 启动子去甲基化[1]

Cell Proliferation Assay[1]

Cell Line: diffuse large B-cell lymphoma (DLBCL) cell lines SUDHL-4, SUDHL-6, DB; normal human cell lines HK-2, MIN-6
Concentration: 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4 μM
Incubation Time: 24, 36. 48 h
Result: Inhibited proliferation of DLBCL cells in a dose- and time-dependent manner.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
