Biological Activity
IC50: 0.25 nM (CD73)[1]
OP-5244 inhibits the production of adenosine (ADO), with an EC50 of 0.79±0.38 nM in H1568 (NSCLC) cells[1].
OP-5244 inhibits AMP hydrolysis to ADO in peripheral blood derived CD8+ T cells with an EC50 of 0.22 nM[1].
OP-5244 (4.1-1000 nM; 96 h) rescues AMP-suppressed CD8+ T cells proliferation and cytokine production[1].
OP-5244 (0.01 nM-10 μM) inhibits ADO production completely in human and murine cancer cell lines (H1568 and EMT6, respectively)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
OP-5244 (150 mg/kg; p.o. twice daily for 16 d) increases CD8+ T cells infiltration and reverses immunosuppression in mice[1].
OP-5244 (0.2 mg/kg; i.v.) exhibits terminal elimination half-lives (rat 8.5, dog 0.82, cyno 4.6 h) due to moderate plasma clearance (rat 0.18, dog 1.22, cyno 0.05 L/kg/h) and low steady-state volume of distribution (rat 0.22, dog 0.29, cyno 0.10 L/kg/h)[1].
OP-5244 (10 mg/kg; p.o.) exhibits Cmax (rat 0.82, dog 1.25, cyno 1.72 μM) and AUC (rat 1.96, dog 1.75, cyno 14.2 μM h) [1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 6.5 mg/mL (12.08 mM); Clear solution
This protocol yields a clear solution of ≥ 6.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (65.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 6.5 mg/mL (12.08 mM); Clear solution
This protocol yields a clear solution of ≥ 6.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (65.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
