Biological Activity
| ln Vitro | In a dose-dependent manner, parecoxib sodium (0-200 μM; 24-48 hours) suppresses the growth of GBM cells [4]. Parecoxib sodium (200 μM; 24-48 hours) decreased U343 cells' ability to migrate when compared to the PBS-treated group [4]. |
| ln Vivo | In the elevated plus maze test, parecoxib sodium (ip; 2.5, 5.0, or 10 mg/kg; once daily; 21 days) had no effect on locomotor activity, but parecoxib 5 and 10 mg/kg was found to have a percentage greater level of motor activity. duration of open arms[3]. |
| Cell Assay |
Cell Viability Assay [4] Cell Types: GBM Cells: U251 and U343 Cell Tested Concentrations: 0 μM, 20 μM, 50 μM, 100 μM and 200 μM Incubation Duration: 24-48 hrs (hours) Experimental Results: Result in slower BrdU incorporation into GBM Cells include U251 and U343 cells. |
| Animal Protocol |
Animal/Disease Models: Adult male ICR mouse, 15 weeks old, weighing 25-35 grams [3] Doses: 2.5 mg/kg, 5.0 mg/kg or 10 mg/kg Route of Administration: intraperitoneal (ip) injection; 2.5, 5.0 or 10 mg /kg; one time/day; 21 days Experimental Results: Exercised anxiolytic-like effects in the elevated plus maze test. |

| Additional Infomation |
Parecoxib Sodium is a water-soluble, injectable sodium salt form of parecoxib, an amide prodrug of the cyclooxygenase II (COX-2) selective, non-steroidal anti-inflammatory drug (NSAID) valdecoxib, with anti-inflammatory, analgesic, and antipyretic activities. Upon intravenous or intramuscular administration, parecoxib is hydrolyzed by hepatic carboxyesterases to its active form, valdecoxib. Valdecoxib selectively binds to and inhibits COX-2. This prevents the conversion of arachidonic acid into prostaglandins, which are involved in the regulation of pain, inflammation, and fever. This NSAID does not inhibit COX-1 at therapeutic concentrations and, therefore, does not interfere with blood coagulation. Drug Indication For the short-term treatment of postoperative pain in adults. , For the short-term treatment of postoperative pain. The decision to prescribe a selective COX-2 inhibitor should be based on an assessment of theindividual patient's overall risks (see sections 4. 3, 4. 4). |

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (6.37 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 100 mg/mL (254.84 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.  (Please use freshly prepared in vivo formulations for optimal results.) |
