Özet

In this study, a series of (7-acyl-5-chloro-2-oxo-3H-benzoxazol-3-yl)alkanoic acid derivatives were synthesized and evaluated for their analgesic and anti-inflammatory activities by using the p-benzoquinone-induced writhing test and the carrageenan hind paw edema model, respectively. Acetic acid-induced peritoneal capillary permeability test and serotonin-induced hind paw edema test were also employed for the most active compounds. The test results indicated that (7-acyl-2-oxo-3H-benzoxazol-3-yl)alkanoic acids (Compounds 6 a-c, 8 a-c, 10 a-c) were equally or more potent analgesic and anti-inflammatory agents than aspirin and indomethacin respectively. The compounds 8 a and 8 c, but not 8 b which have the longest carbon chain on alkanoic acid moiety did not induce gastric lesion in mice.
