Product Description

Biological Activity

Description Celecoxib is a selective COX-2 inhibitor with IC50 of 40 nM in Sf9 cells.
Targets COX-2 [1]
(Sf9 cells)
IC50 40 nM
In vitro Celecoxib shows low sensitivity against COX-1 with IC50 of 15 μM. [1] 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. [2]
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. [1] 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).

Protocol(Only for Reference)

Kinase Assay: [1]

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.

Cell Assay: [2]

Cell lines HNE1 and CNE1-LMP1
Concentrations 0-75 μM
Incubation Time 48 hours
Method The antiproliferative effect of Celecoxib on NPC cells is assessed using an MTT assay. Cells are seeded into 96-well plates and allowed to attach for 24 hours. The cells are then treated with increasing concentrations of Celecoxib (0 to 75 μM) dissolved in DMSO (final concentration ≤0.1%) and incubated for up to 48 hours. After the incubation, 20 μL of MTT dye (5 mg/mL) are added to each well and cells are incubated at 37 °C for 4 hours. After removing the supernatants, the crystals are dissolved in DMSO and the absorbance is measured at 490 nm. The half-maximal inhibitory concentration (IC50) values and the 95% confidence intervals are calculated using probit regression using SPSS 15.0 software. The experiment is performed in triplicate and repeated at least three times.

Animal Study: [1]

Animal Models A 0.1 mL aliquot of a 1% solution of carrageenan in 0.9% sterile saline or 1 mg of Mycobacterium butyricum in 50 μL of mineral oil is administered to the right hind foot pad of male Sprague−Dawley rats.
Formulation Celecoxib is dissolved in 0.5% methyl cellulose and 0.025% Tween-20.
Dosages ≤200 mg/kg
Administration Administered via p.o.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results Initial studies examined whether there was a toxic interaction between the PDE5 inhibitor sildenafil and the non-steroidal anti-inflammatory drug celecoxib. In mammary carcinoma cell lines growing in 10% fetal calf serum sildenafil and celecoxib interacted in a greater than additive fashion to kill parental wild type tumor cells as well as anoikis resistant variants of these cells.
