Chalcones are ubiquitous in nature and they are precursors to the flavonoids family. Natural occurring chalcones as well as synthetic chalcone analogues have demonstrated many pharmaceutical effects, including anti-inflammatory, anti-oxidant, anti-parasite, and anti-tumor activities . The synthesis of some substituted chalcones was carried out in alcoholic potassium hydroxide at room temperature by Claisen-Schmidt condensation reaction. The compounds were obtained in good yield and were characterized using the combination of IR and NMR spectroscopy. The antibacterial activity of the synthesized compounds was carried out and they were found to be inactive against the tested strains of micro-organisms. Contrary to the popular belief that most chalcones do exhibit antimicrobial activity, these substituted chalcones lack such activity.
