Özet

Sixteen 1-(2-naphthyloxyacetyl)-4-substituted-3-thiosemicarbazide, 2-(2-naphthyloxymethyl)-5-substitutedamino-1,3,4-oxadiazole, 2-(2-naphthyloxymethyl)-5-substitutedamino-1,3,4-thiadiazole and 5-(2-naphthyloxymethyl)-4-substituted-1,2,4-triazole-3-thione derivatives have been prepared and evaluated as orally active anti-inflammatory agents with reduced side-effects. The structures of the compounds were confirmed by IR and H-1 NMR spectral data and microanalysis. The anti-inflammatory and ulcerogenic activities of the compounds were compared with naproxen, indomethacin and phenylbutazone. In carrageenan-induced foot pad edema assay, 2-(2-naphthyloxymethyl)-5-methylamino-1,3,4-oxadiazole, 5-(2-naphthyloxymethyl)-4-methyl-1,2,4-triazole-3-thione and 5 -(2-naphthyloxymethyl)-4-ethyl-1,2,4-triazole-3-thione showed an interesting anti-inflammatory activity. In the air-pouch test, 1,3,4-oxadiazole and 1,2,4-triazole-3-thione derivatives reduced total number of leukocytes of the exudate that indicates excellent inhibition of prostaglandin production. Side effects of the compounds were examined on gastric mucosa, liver and stomach and none of the compounds showed significant side effects compared with reference nonsteroidal anti-inflammatory drugs (NSAIDs).
