Curcumin analogs are synthesized with solid support under the concept of green chemistry, i.e. in the absence of organic solvents or hazardous chemicals using silica-sulfuric acid under solvent free conditions. Their structures are established through infrared, NMR, and mass spectroscopy and elemental analysis. The antibacterial activities of the synthesized curcumin analogs are evaluated against three human pathogenic Gram negative bacteria, taking ciprofloxacin as standard compound. Most compounds exhibit some antibacterial activity, with an efficacy depending upon nature and position of the phenyl substituents.
