Kinase experiment:

To measure the effects of DC-05 on mouse DNMT1 activity, 200 nM purified DNMT1 is incubated with 200 μM of DC-05 and S-adenosylmethionine (AdoMet) in the DNMT assay buffer in the assay plate at 37℃ for 2 h. Next, every sample is incubated with the capture and detection antibody, followed by incubation with developer solution for 10 min at room temperature. The absorbance is measured at 450 nm using a microplate reader. S-Adenosylhomocysteine (AdoHcy) is used as a positive control[1].

DC-05 is a DNA methyltransferase 1 (DNMT1) inhibitor, with an IC50 and a Kd of 10.3 μM and 1.09 μM, respectively.

DC-05 is a DNA methyltransferase 1 (DNMT1) inhibitor, with an IC50 and a Kd of 10.3 μM and 1.09 μM, respectively. DC-05 shows less potent activities against DNMT3A, DNMT3B, G9a, SUV39H1, MLL1, SET7/9, and PRMT1 (IC50: >200, >200, >150, >150, >150, >150, 37.1 μM). DC-05 (1.25, 2.5, 5, and 10 μM) potently inhibits the proliferation of HCT116 (human colon cancer) and Capan-1 (human pancreatic adenocarcinoma cells) after treatment for 24, 48, and 72 h[1].
