Description: Mefenamic Acid (CI-473; CN-35355; CI 473; CN 35355; Mefenamic Acid; Ponstel; Parkemed; Coslan), a nonsteroidal anti-inflammatory drug (NSAID), is potent, nonselective, competitive inhibitor of the enzymes COX-1 and COX-2 with anti-inflammatory activity. Mefenamic acid displays a wide range of biological acitivity such as anti-inflammatory, analgesic, and antipyretic properties. It also demonstrated potent anti-proliferative activity in vitro against colorectal cancer cells.

In vitro activity: Mefenamic acid is a non-steroidal anti-inflammatory agent, acting as a competitive inhibitor of hCOX-1, with IC50s of 40 nM and 3 μM for hCOX-1 and hCOX-2, respectively. Mefenamic acid (0-100 μM) has cytotoxic effects on KB, Saos-2, and 1321N cells, however, U-87MG cells are resistant to Mefenamic acid.
Cell Assay: Powder forms of Mefenamic acid, indometacin, aspirin, and celecoxib are dissolved in 0.1% dimethyl sulfoxide (DMSO) to achieve a concentration of 100 μM of stock solution, which is sterilized by filtration through a 0.22-µm filter and then stored at 4°C. Different concentrations (100, 50, 25, 10, and 5 μM) of the drugs (Mefenamic acid, etc.) are prepared by serial dilutions with the FCS-free medium or the medium containing 10% FCS in sterile plastic centrifuge tubes
