Biological Activity

COX-2 0.1 μg/mL (IC50) |
carbonic anhydrase |
Polmacoxib (CG100649) (0-1 μg/ml; 24 hours; HCA-7 and HT-29 cells) can inhibit COX-2 activity and PGE2 production in human colon cancer cells, at lower concentrations compared to Celecoxib[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Polmacoxib (7-15 mg/kg; p.o.; daily from day 27 post-injection to day 111; athymic nude mice; subcutaneous xenograft mouse model) reduces tumor volume and tumor weight by 58% and 48%, respectively, compared to a 48% and 36% reduction following treatment with Celecoxib[2].
Polmacoxib (7-15 mg/kg; p.o.; began on day 14 and continued for 8 weeks; athymic nu/nu mice; orthotopic xenograft mouse model) inhibits CRC growth in an orthotopic xenograft mouse model, reducing tumor weight by 70% using 7 mg/kg or by 83% using 15 mg/kg, compared to a similar 70% reduction following treatment with 500 mg/kg of Celecoxib[2].

Solvent & Solubility
DMSO : 250 mg/mL (691.77 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (5.76 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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 enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
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.
