Özet

Sixteen 1-(1-naphthyloxy)acetyl-4-substituted-3-thiosemicarbazides, 2-substituted amino-5-(1-naphthyloxy)methyl-1,3,4-oxadiazoles, 2- substitutedamino-5-(1-naphthyloxy) methyl-1,3,4-thiadiazoles and 3-(1-naphthyloxy)methyl-4-substituted-1,2,4-triazole-5-thiones were synthesized. The structures of the compounds have been elucidated by UV, IR, 1H-NMR, 13C-NMR spectra and elemental analysis. The anti-inflammatory activities of the compounds were evaluated by carregeenan induced hind paw edema and air-pouch inflammation tests in mice. In carrageenan induced hind paw edema test, compounds 1a, 1d, 3d, 4a showed equivalent or higher activity compared to naproxen and phenylbutazone. In the air-pouch inflammatory model, compounds 1a, 1b, 1d, 2c, 3c, 3d, 4a and 4d showed marked anti-inflammatory activity. The ED50 values of these compounds ranged between 24-36 mg/kg. Side effects of the compounds on gastrointestinal system and kidneys were examined and none of the compound showed significant side effects.
