Biological target:
Mefenamic acid is a non-steroidal anti-inflammatory agent, acting as a competitive inhibitor of hCOX-1 and hCOX-2, with IC50s of 40 nM and 3 μM for hCOX-1 and hCOX-2, respectively.
In vitro activity:
Mefenamic acid exerted cytotoxic effects on KB, Saos-2, and 1321N cells, where the viability was approximately 75%. U-87MG cells were resistant to mefenamic acid. Reference: J Dent (Shiraz). 2016 Sep;17(3):219-25. https://pubmed.ncbi.nlm.nih.gov/27602398/
In vivo activity:
Tumor-bearing mice were received MEF (mefenamic acid) at a dose of 25 mg/kg for 6 successive days. MEF treatment in IR exposure mice showed a significant increase in the immunoreactivity of caspase-3 in the colon tumor tissue. MEF has an anti-tumor effect in colon tumor-bearing mice.
