Syntheses and evaluation of anti-inflammatory, analgesic and ulcerogenic activities of 1,3,4-oxadiazole and 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole derivatives

Abstract

Several 2,5-disubstituted-1,3,4-oxadiazoles (4a–f) and 3,6-disubstituted-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles (7a–f) were synthesized and characterized by elemental analyses and spectral data. These compounds were screened for their anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation activities. Compound 7c showed excellent anti-inflammatory and remarkable analgesic activity with reduced ulcerogenic and lipid peroxidation activity when compared with ibuprofen.

Keywords::

• Anti-inflammatory
• analgesic
