Abstract

Eighteen new 1-N-substituted-3,5-diphenyl-2-pyrazoline derivatives have been synthesized and cyclooxygenase (COX-1 and COX-2) inhibitory activities have been evaluated. The results of these biological assays showed that all of new derivatives are not endowed with improved anti-inflammatory activity against COX-1, but some of them showed a good activity against COX-2. To evaluate the binding mode of the most significative compounds ( 2d, 2f, 2g and 2k) docking studies were carried out. These studies confirmed biological data, in fact these compounds were able to fit into the active site of COX-2.
