  • [Show abstract] [Hide abstract] ABSTRACT: A series of 1,2,5-trisubstituted 4(1H)-pyridinone derivatives (7-14) were synthesised by using 4-pyrone derivatives with primary amines in ethanol. The structures of the synthesised compounds were confirmed by analytical and spectral data (UV, IR and 1H-NMR and microanalysis). Analgesic and antiinflammatory activities of the synthesised compounds were investigated by acetic acid-induced writhing syndrome and carrageenan rat paw edema tests. All of the test compounds exhibited higher analgesic activities than acetyl salicylic acid and showed higher antiinflammatory activities than indomethacin. The anti-inflammatory activity and gastric ulceration potential of the compounds were tested using indomethacin as reference drug.

  • [Show abstract] [Hide abstract] ABSTRACT: This paper describes recent results of a research program aimed at the synthesis and pharmacological evaluation of new 4(1H)-pyridinone derivatives belonging to the 1,3-disubstituted series (4-11). These compounds were structurally planned by applying the molecular hybridization strategy on previously described 1,2-disubstituted-4(1H)-pyridinone derivatives, considered as lead compounds, which present potent analgesic properties (M.D. Aytemir, T. Uzbay, D.D. Erol, Arzneim. Forsch. (Drug Res.) 49 (1999) 250). Their chemical structures have been proved by means of their IR and 1H NMR data and by elemental analysis. The analgesic profile of the title compounds (4-11), evaluated by the model of abdominal constrictions induced by acetic acid, showed that all the 4(1H)-pyridinone derivatives were active, exhibiting an analgesic activity comparable with that of aspirin (acetyl salicylic acid) used as a standard. The antiinflammatory profile of the synthesized compounds, evaluated by the model of carrageenan rat paw edema, showed that all compounds were active and were comparable with indomethacin used as a standard.
