DI-87

SKU: orb1691229

Description

DI-87 (TRE-515) is a potent, orally bioavailable small molecule inhibitor of deoxycytidine kinase (dCK). By blocking dCK-mediated phosphorylation, it reduces dNTP pools, induces S-phase arrest, and demonstrates synergistic antitumor activity with thymidine in preclinical models. This inhibitor is a valuable research tool for investigating nucleotide metabolism and combination therapies in oncology.

Bioactivity

• Target IC50:
  DCK:10.2 nM (EC50)
• In Vivo:
  Methods: Female NSG mice bearing CEM tumors were treated with DI-87 (10, 25, or 50 mg/kg, orally) and DI-87 plasma and tumor concentrations were assessed. Results: Plasma DI-87 concentrations peaked between 1 and 3 hours; tumor concentrations were lower than plasma and had a later, more sustained peak at 3-9 hours.
• In Vitro:
  Methods: CEM cells were seeded at 1 × 10 3 cells/well in white opaque 384-well plates at 50 μl/well and treated as indicated. After incubation with increasing concentrations (2 nM-10 μM) of gemcitabine and 1 μM DI-87 for 72 h, 50 μl of CellTiter-Glo reagent (diluted 1:5 in dH2O) was added to each well, the plates were incubated at room temperature for 5 m, and luminescence was measured using a BioTek microplate luminometer. Results: The cytotoxic effect of gemcitabine requires dCK, and administration of DI-87 completely blocked cytotoxicity after gemcitabine treatment, demonstrating dCK inhibition by DI-87.
