Abstract
A new series of coupled benzofuran derivatives that contain the trifluoromethyl group and pyrazole moiety is synthesized for evaluation of their anti-inflammatory and analgesic activities. Their synthesis proceeds via cyclocondensation of 2-hydroxy-4-(trifluoromethyl)benzaldehyde with chloroacetone with formation of 2-acetylbenzofuran, which upon treatment with different aldehydes via the Claisen-Schmidt condensation gives the corresponding chalcones. Cyclization of chalcones with hydrazine hydrate leads to pyrazoline derivatives, that exhibit significant anti-inflammatory and analgesic activities. Docking modelling of selected active compounds are correlated well with their anti-inflammatory tests data.
