Abstract
Background: Infection is a global threat to human health, and there is an urgent need to develop new effective antibacterial drugs to treat bacterial infections.
Objective: To study the antibacterial activity of piperazine substituted chalcone sulphonamides.
Materials and Methods: A series of novel piperazine substituted chalcone sulphonamides have been prepared, and in vitro antibacterial activity against Staphylococcus aureus, Bacillus subtilis and Escherichia coli strains were evaluated.
Results: The results showed that derivatives 6a, 6c and 6h displayed good antibacterial activity against Bacillus subtilis with MIC values of 4.0-8.0 mg/mL.
Conclusion: Piperazine substituted chalcone sulphonamides may be used as potential antibacterial agents.
Keywords: Chalcone, sulphonamide, antibacterial activity, MIC, piperazine, Staphylococcus aureus.
