Abstract

Two new series of 1,5-diaryl pyrazoline (3a-f) and 1,5-diaryl pyrazole (5a and 5b) were designed as both COX-2 and 15-LOX inhibitors. All the prepared compounds were fully characterized by all spectral and element analysis. Their anti-inflammatory activity and ulcer index were included. Pyrazoline 3f is the most effective with IC50=1.14 and 4.7μM against COX-2 and 15-LOX respectively, and more potent than celecoxib and meclofenamate references. In addition 3a, 3b, 5a, and 5b were safer with low ulcer index than celecoxib. Docking study was performed for the most active compounds such as 2b, 3a, and 3f on COX-2 and 15-LOX enzymes.
