Nitric oxide-donating non-steroidal anti-inflammatory drugs: the case of nitroderivatives of aspirin
摘要:
Nitric oxide (NO) acts as a key signalling mechanism in a number of cells and tissues in the mammalian organism. Modulation of the biosynthesis of NO has emerged to be relevant to the treatment of a variety of human diseases. In the attempt to reduce the serious side effects of non-steroidal anti-inflammatory drugs (NSAIDs), especially in the gastrointestinal tract, a NO-releasing moiety has been linked to conventional NSAIDs. A prototypical example is that of NO-releasing derivatives of aspirin. Thanks to the cytoprotective action of NO such compounds do not produce gastric damage and are emerging as an interesting novel group of drugs for their unique pharmacological properties.

The synthesis and study of a novel series of potential prodrugs of indomethacin, ketoprofen, ibuprofen and aspirin are reported. 2-Formylphenyl esters of the NSAIDs, together with two 6-substituted 2-formyl and two 2-acylphenyl aspirins and 4-formylphenylindomethacin, have been prepared. A study of their alkaline and neutral hydrolysis shows that these compounds, with the exception of 2-acetylphenyl aspirin, act as true prodrugs of the NSAIDs, giving the NSAID and acylphenol. The rates of hydrolysis and activation parameters indicate that the 2-acylphenyl esters employ an intramolecular catalytic route. The 2-formylphenyl testers were more potent as anti-inflammatory agents than the parent compounds in the carragheenan-induced paw oedema test. (C) 1998 Elsevier Science S.A. All rights reserved.
