Abstract

A new series of co-drugs was designed based on hybridising the dihydropteroate synthase (DHPS) inhibitor sulphonamide scaffold with the COX-2 inhibitor salicylamide pharmacophore through biodegradable linkage to achieve compounds with synergistic dual inhibition of COX-2/PGE2 axis and DHPS enzyme to enhance antibacterial activity for treatment of septicaemia. Compounds and demonstrated potent COX-2 inhibitory activity comparable to celecoxib. and exhibited ED lower than celecoxib in carrageenan-induced paw edoema test with % PGE2 inhibition higher than celecoxib. Furthermore, , and showed gastric safety profile like celecoxib. Moreover, antibacterial screening revealed that, showed activity against higher than sulfasalazine. While, revealed activity against higher than sulfasalazine and against comparable to sulfasalazine. Compound achieved the target goal as potent inhibitor of COX-2/PGE2 axis and broad-spectrum antibacterial activity against induced septicaemia in mice.
