DC_517 is a DNA methyltransferase 1 (DNMT1) inhibitor, with an IC50 and a Kd of 1.7 μM and 0.91 μM, respectively. DC_517 (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. DC_517 (0, 0.75, 1.5, and 3 μM) also dose-dependently induces apoptotic cell death in HCT116 cells[1].

To measure the effects of DC_517 on mouse DNMT1 activity, 200 nM purified DNMT1 is incubated with 200 μM of DC_517 and S-adenosylmethionine (AdoMet) in the DNMT assay buffer in the assay plate at 37°C 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].
