Celecoxib

Protocol

Kinase experiment [1]:

COX enzyme assay in vitro

Expression of COX protein in insect cells was 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 were homogenized and incubated with arachidonic acid (10 μM). COX activity was determined by monitoring PG production. No COX activity was detected in mock-infected Sf9 cells. Celecoxib were preincubated with crude 1% CHAPS homogenates (2 ~ 10 μg of protein) for 10 mins before addition of arachidonic acid. PGE2 formed was detected by ELISA after 10 min incubation.

Cell experiment [2]:

Cell lines

A549 cells

Preparation method

The solubility of this compound in DMSO is > 19.1 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

0 ~ 10 μM

Applications

In A549 cells, Celecoxib (≤ 10 μM) and PGE2 (≤ 12.5 μM) showed no effect on cell viability. However, Celecoxib reversed PGE2 (10 μM) increased migration and invasion of A549 cells.

Animal experiment [2]:

Animal models

Mice received unilateral pneumonectomy

Dosage form

100 mg/kg; p.o.; q.d.

Applications

In mice received unilateral pneumonectomy, Celecoxib inhibited increased metastasis of A549 cells. Moreover, Celecoxib significantly inhibited the increase in PGE2 plasma level as well.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Celecoxib is a highly selective inhibitor of cyclooxygenase-2 (COX-2) with IC50 value of 40nM [1].

In vitro, celecoxib not only reduced the production of PGE2 but also inhibited the downstream effects of PGE2. Celecoxib blocked migration and invasion of A549 cells increased by PGE2 in the wound healing and transwell assays.  Additionally, celecoxib reduced MMP9 mRNA expression which was increased by PGE2. Moreover, celecoxib enhanced E-cadherin mRNA expression which was inhibited by PGE2 [2].

In vivo, celecoxib inhibited the increase in metastases of A549 cells and significantly reduced the increase in PGE2 plasma level in mice receiving unilateral pneumonectomy [2].
