Biological Activity

Description Indomethacin (NSC-77541, Indometacin) is a nonselective COX1 and COX2 inhibitor with IC50 of 0.1 μg/mL and 5 μg/mL, respectively, used to reduce fever, pain, stiffness, and swelling.
Targets
COX1 [6] COX-2 [6]
0.28 μM 14 μM
In vitro

Indomethacin inhibits transcription of a beta-catenin/TCF-responsive reporter gene in a dose dependent manner. Indomethacin also downregulates the beta-catenin/TCF transcriptional target cyclin D1. Indomethacin attenuates the transcription of beta-catenin/TCF-responsive genes, by modulating TCF activity without disrupting beta-catenin/TCF complex formation. [1]

In vivo Indomethacin increases BrdU+ cells of all lineages and reduces microglial/monocyte activation in rats after focal cerebral ischemia. [2] Indomethacin (7.5 mg/kg, one injection) produces acute injury and inflammation in the distal jejunum and proximal ileum that are maximal at three days and completely resolves within one week. Indomethacin (two daily subcutaneous injections) produces a more extensive and chronic inflammation that lasts in an active form in more than 75% of the rats for at least two weeks. [3] Indomethacin (4ppm) reduces tumor yield by 78% in SKH:HR-1-hrBr hairless mice. [4] Indomethacin (20 mg/kg, orally) increases the total area of gastric erosions and concentration of lipid peroxides in the gastric mucosa of rats. Indomethacin increases the alpha-tocopherol:total cholesterol ratio in serum. Indomethacin inhibits the increases in gastric mucosal erosions and lipid peroxides in the gastric mucosa, and the reduction of serum alpha-tocopherol. [5]
