A series of 1-aroyl-3-aryl thioureas derivatives were synthesized and evaluated for antibacterial activity. The results indicated that the compounds possessed higher activity against gram-negative bacteria than gram-positive bacteria. Amongst all these compounds, C18 (89.4%) exhibited the greatest antibacterial activity against gram-negative bacteria while C5 (85.6%) displayed maximum antibacterial activity against gram-positive bacteria. Preliminary study of the structure-activity relationship revealed that an electronic factor on aryl rings had a great effect on the antibacterial activity of these compounds.
