New carboxamides bearing benzenesulphonamides: Synthesis, molecular docking and pharmacological properties.

Ten new derivatives of benzenesulphonamide bearing carboxamide functionality were synthesized and investigated for their in vitro antimicrobial, antioxidant and in vivo anti-inflammatory activities. Compound 9d inhibited carrageenan induced rat-paw oedema at 93.81, 88.79 and 86.09% at 1 h, 2 h and 3 h administration respectively. In the antimicrobial activity, compound 9a (6.54, 6.69 and 6.64 mg/mL) was most potent against S. aureus, B. subtilis and C. albicans respectively, compound 9e (6.45 and 6.46 mg/mL) was most active against P. aeruginosa and A. niger respectively while compound 9i (6.24 mg/mL) was most active against E. coli. Only compound 9a (IC 0.3052 mg/mL) had comparable activity with Vitamin C (IC 0.2090 mg/mL) in the antioxidant assay.
