Several N-alkyl- and N-arylacetoamides have been self-condensed to form pyridones.N-Alkylacetoacetamides give 2-pyridones, while N-arylacetoamides give 4-pyridones.In an attempt to develop nonacidic, nonsteroidal antiinflammatory agents, the pyridones were tested in a carrageenan-induced pedal edema assay in rats.While the 2-pyridones were not active, 9 of 17 4-pyridones tested were active, and one compound (4g) had antiinflammatory efficacy in a dose-response assay (ED50 values).Most compounds were considered nontoxic by determination of approximate LD50 values in mice by a standard multidimensional observational assay.
