DETAILS

DrugBank - DB00482

• Drug Groups: approved; investigational
• Description: Celecoxib is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of osteoarthritis, rheumatoid arthritis, acute pain, painful menstruation and menstrual symptoms, and to reduce numbers of colon and rectum polyps in patients with familial adenomatous polyposis. It is marketed by Pfizer under the brand name Celebrex. In some countries, it is branded Celebra. Celecoxib is available by prescription in capsule form.
• Indication: For relief and management of osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis, acute pain, primary dysmenorrhea and oral adjunct to usual care for patients with familial adenomatous polyposis
• Pharmacology: Celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Celecoxib is used to treat rheumatoid arthritis, osteoarthritis, and familial adenomatous polyposis (FAP). Because of its lack of platelet effects, celecoxib is not a substitute for aspirin for cardiovascular prophylaxis. It is not known if there are any effects of celecoxib on platelets that may contribute to the increased risk of serious cardiovascular thrombotic adverse events associated with the use of celecoxib. Inhibition of PGE2 synthesis may lead to sodium and water retention through increased reabsorption in the renal medullary thick ascending loop of Henle and perhaps other segments of the distal nephron. In the collecting ducts, PGE2 appears to inhibit water reabsorption by counteracting the action of antidiuretic hormone.
• Toxicity: Symptoms of overdose include breathing difficulties, coma, drowsiness, gastrointestinal bleeding, high blood pressure, kidney failure, nausea, sluggishness, stomach pain, and vomiting.
• Affected Organisms: Humans and other mammals
• Biotransformation: Hepatic. Celecoxib metabolism is primarily mediated via cytochrome P450 2C9. Three metabolites, a primary alcohol, the corresponding carboxylic acid and its glucuronide conjugate, have been identified in human plasma. These metabolites are inactive as COX-1 or COX-2 inhibitors.
• Absorption: Well absorbed in the gastrointestinal tract. When taken with a high fat meal, peak plasma levels are delayed for about 1 to 2 hours with an increase in total absorption (AUC) of 10% to 20%.
• Half Life: Approximately 11 hours.
• Protein Binding: 97%, primarily to albumin and, to a lesser extent, a₁-acid glycoprotein.
• Elimination: Celecoxib is eliminated predominantly by hepatic metabolism with little (<3%) unchanged drug recovered in the urine and feces.
• Distribution: * 400 L
• Clearance: * 500 mL/min

Research Area

• Description: Prostate cancer

Biological Activity

• Description: Celecoxib is a selective COX-2 inhibitor with IC50 of 40 nM.
• Targets: COX-2
• IC50: 40 nM ^[1]
• 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). ^[3]
• Clinical Trials: Celecoxib is currently in Phase II clinical trials in patients with recurrent respiratory papillomatosis.

Combination Therapy

• Description: Combination treatment of Celecoxib and dehydroxymethyl-epoxyquinomicin (DHMEQ), an inhibitor of NF-κB produces the synergistic inhibitory effects on cell growth, NF-κB p65 DNA-binding capacity, and cell proliferation in HA22T/VGH and Huh-6 cell lines. ^[4] Combination of SC-560 and Celecoxib shows better antitumor activity with about 35.54% inhibition of tumor growth on human ovarian SKOV-3 carcinoma cells xenograft-bearing mice, while SC-560 and Celecoxib alone only results in inhibition of tumor growth by 13.57% and 15.16%, respectively. ^[5] Combination therapy of Celecoxib and cyclophosphamide is currently in Phase II clinical trials in patients with recurrent or persistent ovarian epithelial, fallopian tube, or primary peritoneal cancer.

Protocol

• Protocol: 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.
• Protocol: Cell Assay ^[2]
• Cell Lines: HNE1 and CNE1-LMP1
• Concentrations: 0-75 μM
• Incubation Time: 48 hours
• Methods: 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.
• Protocol: 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.
• Doses: ≤200 mg/kg
• Administration: Administered via p.o.
