derivative of compound 14 and a Mannich base derivative of compound 12 were synthesized from the reactions of these precursors with methyl iodide and methyl piperazine, respectively. All newly synthesized compounds were screened for their antimicrobial activities. The antimicrobial activity study revealed that all the compounds screened showed good or moderate activity except compounds 3, 5c, 7, 9c

possessing N-2 Mannich bases or S-alkyl substituents, is reported. Several of them exhibited a low nanomolar COX enzyme inhibition activity. Most of the compounds showed inhibition of edema was similar to that evoked by celocoxib in animal model. Molecular docking studies of the compounds into the binding sites of COX-1 and COX-2 allowed us to shed light on the binding mode of these novel COX inhibitors
