Tumors were resected from mice 10 days after orthotopic inoculation of 4T1-Luc2 cells, and hydrogels loaded with the following payloads were evaluated: anti–PD-1, anti-CTLA-4, IL-15sa, lenalidomide, celecoxib, STING-RR, or R848. Mice that did not receive a hydrogel were examined as a negative control. (A) IVIS imaging of 4T1-Luc2 cells is shown for all groups described and illustrates tumor burden.

Reduced hepatic lipid contents and alleviated liver injury in EC-AMPK mice treated with selective COX-2 inhibitors. Wild-type and EC-AMPK mice given a high fat diet were treated with vehicle, celecoxib or nimesulide for a period of 4 weeks. At the end of treatment, parameters including body weight and circulating glucose (A), serum triglyceride and cholesterol levels (B were measured and presented as percentage comparisons against those from vehicle-treated wild-type mice. *P < 0.05 versus wild-type mice treated with vehicle; #P < 0.05 versus EC-AMPK mice treated with vehicle, n = 3-5.

Breast cancer cells, wild type (WT) or anoikis resistant (AR) variants, were treated with celecoxib (CEL 5.0 uM) and/or sildenafil (SIL, 2.0 uM). Cells were isolated after 24h and viability determined by trypan blue exclusion (n = 3, +/- SEM) * p < 0.05 greater than corresponding value in vehicle control. Upper inset pictures: HCC38 cells in 96 well plates were treated with celecoxib (CEL 5.0 uM) and/or sildenafil (SIL, 2.0 uM). Cells were isolated after 24h and viability determined using a live-dead assay (red cells = dead; green cells = alive) (n = 3, +/- SEM) * p < 0.05 greater than corresponding value in vehicle control.

Effect of celecoxib on the in vitro proliferation of BRAFV600E and NRASQ61R melanoma cell lines. a BRAFV600E A375 and NRASQ61R SK-MEL-2 melanoma cells were seeded at the density of 3 × 103 per well in a 96-well plate and incubated with the indicated concentrations of celecoxib. Untreated cells were used as a control. DMSO (vehicle of celecoxib) concentration was maintained at 0.02% in all wells. Following a 24 h incubation at 37℃ in a 5% CO2 atmosphere, growth inhibition was determined by MTT assay. Data are expressed as mean percent of proliferation ± SD of treated cells as compared to untreated control cells. Mean percent of proliferation and SD were calculated from three independent experiments performed in triplicate. Difference between doses of celecoxib was calculated using unpaired t-test. *** indicate P < 0.001. b BRAFV600E A375 and NRASQ61R SK-MEL-2 melanoma cells were seeded at the density of 4 × 105 per well in a 75 cm2 tissue culture flask and incubated with celecoxib (60 μM). Untreated cells were used as a control. DMSO (vehicle of celecoxib) concentration was maintained at 0.02% in all wells. Following a 24 h incubation at 37℃ in a 5% CO2 atmosphere, viability of cells was determined by trypan blue assay. Data are expressed as mean percentage of viable (negative) and death cells (positive) of treated cells as compared to untreated control cells. *** indicate P < 0.001

|Description||Celecoxib is a selective COX-2 inhibitor with IC50 of 40 nM in Sf9 cells.|
Celecoxib shows low sensitivity against COX-1 with IC50 of 15 μM.  Celecoxib shows an anti-proliferative effect on nasopharyngeal carcinoma (NPC) cell lines including HNE1 and CNE1-LMP1 with IC50 of 32.86 μM and 61.31 μM, respectively. 
|In vivo||Celecoxib exhibits a potent, oral anti-inflammatory activity. Celecoxib reduces acute inflammation in the carrageenan edema assay and chronic inflammation in the adjuvant arthritis model with ED50 of 7.1 mg/kg and 0.37 mg/kg/day, respectively. In addition, Celecoxib also exhibits analgesic activity in the Hargreaves hyperalgesia model with ED50 of 34.5 mg/kg. Besides, Celecoxib produces no acute GI toxicity in rats at doses up to 200 mg/kg and no chronic GI toxicity in rats at doses up to 600 mg/kg/day over 10 days.  In a C3Hf/KamLaw female mouse model, Celecoxib increases median survival time of 105 days (range, 79-145 days) after 13.5 Gy local thoracic irradiation (LTI) alone to 142 days (range, 94-155 days). |
COX enzyme assay in vitro:Expression of COX protein in insect cells is determined by assessing PG-synthetic capability in homogenates from cells incubated for 3 days with COX-1 or COX-2 baculovirus. Cells expressing COX-1 or COX-2 are homogenized and incubated with arachidonic acid (10 μM). COX activity is determined by monitoring PG production. No COX activity is detected in mock-infected Sf9 cells. Celecoxib are preincubated with crude 1% CHAPS homogenates (2-10 μg of protein) for 10 minutes before addition of arachidonic acid. PGE2 formed is detected by ELISA after 10 minute incubation.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
