New tilomisole-based benzimidazothiazole derivatives were designed and synthesized in this work. Their anti-inflammatory activity was assessed through the in vivo carrageenan rat paw edema model, and the in vitro COX inhibition assay. Compounds 13, 20, 30, 40, 43, and 46 demonstrated values of inhibition of induced edema in the in vivo assay comparable to celecoxib. All the synthesized compounds expressed their activity on COX-2 enzyme more than COX-1, proving their advantageous selectivity. In addition, compounds 13, 16, 20, 25, and 46 displayed lower IC50 values than celecoxib as a reference drug against COX-2 enzyme; having values of 0.09, 13.87, 32.28, 33.01, and 5.18 nM resp. vs 40.00 nM for celecoxib. Particularly, the most active compound (13) with its extreme potency (400 folds more potent than celecoxib) exhibited a notable high selectivity index (SI = 159.5). In silico studies, including ADMET prediction, compliance to Lipinski′s rule of five, and mol. docking into the active site of both COX isoenzymes were conducted for the synthesized compounds The results suggested that these compounds are good candidates for orally active drugs, and docking revealed higher number of interactions with COX-2 for 13 as the most active compound compared with COX-1 reflecting its advantageous selectivity and explaining its extreme potency.
