Piroxicam (CP-16171) is a non-steroidal anti-inflammatory drugs, acts as a COX inhibitor, with IC50s of 47, 25 μM for human monocyte COX-1 and COX-2, respectively[1]. Piroxicam (CP-16171) (167, 333, 500 μM) decreases cell population of T24 and the 5637 cells. Piroxicam (CP-16171) (500 μM) also reduces the cell viability of T24 and 5637 cell, and is significantly effective when combined with 0.05 μM carboplatin. The combination also inhibits Ki-67 expression in booth cells[3].

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 (7.54 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 (7.54 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.

Protocole
Urinary bladder cancer cell lines are treated with graded concentrations of carboplatin (0.05, 0.5 and 1 μM) and Piroxicam (CP-16171) (167, 333 and 500 μM) for 72 h to assess dose-response profiles. For the combination approach, 0.05 μM of carboplatin is used with 333 μM Piroxicam. Both drugs are freshly prepared before each experiment. An untreated control group (cells not exposed to carboplatin and Piroxicam) is used for all assays[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Dogs[2]
Dogs undergo tumor staging, including thoracic and abdominal radiography, cystography, ultrasonography, and cystoscopy (with collection of tissue samples) before treatment and after 4 weeks of Piroxicam (CP-16171) (0.3 mg/kg qd 24-h p. o.) treatment. Dogs receive no other cancer treatment during the 4 weeks of Piroxicam (CP-16171) treatment. Tissue samples are immediately frozen in liquid nitrogen for PGE2 analysis or fixed in 10% neutral buffered formalin for immunohistochemical examination. Urine is also collected before and after Piroxicam treatment, aliquoted, and then stored at −80°C until analyzed[2].
