Oxaprozin
Based on 1 Customer Validation
Oxaprozin is an orally active and potent COX inhibitor, with IC50 values of 2.2 μM for human platelet COX-1 and and 36 μM for IL-1-stimulated human synovial cell COX-2, respectively. Oxaprozin also inhibits the activation of NF-κB. Oxaprozin induces cell apoptosis. Oxaprozin shows anti-inflammatory activity. Oxaprozin-mediated inhibition of the Akt/IKK/NF-κB pathway contributes to its anti-inflammatory properties.

IKK |
Oxaprozin induces apoptosis in a dose-dependent manner. Oxaprozin increases caspase-3 activity in the activated but not in the resting condition. NF-κB activation is inhibited by Oxaprozin (50 μM). Oxaprozin inhibits activation of the IKK system induced by the reagent IκBα[1].
Oxaprozin (100 μM) induces the strongest proapoptotic effect and significantly increases CD40L-treated monocyte apoptosis. Oxaprozin treatment inhibits CD40L-induced Akt and NF-κB (p65) phosphorylation[2].

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: ≥ 2.5 mg/mL (8.52 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (8.52 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocole
Caspase 3 activity in the presence or absence of 200 ng/mL CD40L plus 1 μg/mL CD40L enhancer and 100 μM Oxaprozin is performed. The enzymatic activity is spectrophotometrically determined for 60 minutes at 405 nm assuming an extinction coefficient of 8.8×103 M1/cm[2].

Purified monocytes are resuspended at 106/mL and cultured for 48 hours. In selective experiments, cells are cultured in the presence or absence of 50 μM PD98059, 1 μM SB203580, 50 μM LY294002, 20 μM SN-50, 50 μM Ac-DEVD-CHO, different doses (5, 10, 50, 100 μM) of Oxaprozin, 100 μM ibuprofen,100 μM indomethacin, or 100 μM naproxene. Percentages of apoptotic cells are measured by both fluorescence microscope and flow cytometer[2].
