NO-Indomethacin

NO-indomethacin is a hybrid molecule of indomethacin and a nitric oxide (NO) donor. This drug design combines the anti-inflammatory properties of a non-steroidal anti-inflammatory drug (NSAID) with the gastrointestinal protective effects of NO. Compounds of this class retain their anti-inflammatory and analgesic activity, but have reduced gastrointestinal and kidney toxicity compared to the NSAID alone. NO-indomethacin also enhances the cancer chemopreventative activity of indomethacin. NO-indomethacin exhibits an IC50 of 82 μM, compared to >1, 000 μM for indomethacin alone, for the inhibition of pancreatic cancer cell (PaCa-2) growth after 24 hours in culture.
