Synthesis, characterization and antinociceptive activities of Novel 2-[2,4-dichlorophenyl]-4H-chromen-4-one

A novel flavone derivative has been synthesized in good yield from ketone and aldehyde. The structure has been established by different spectroscopic techniques like H NMR, C NMR, IR and elemental analysis. The compound was then screened for its acute toxicity and antinociceptive activity studies on animal model. The novel compound was safe upto a maximum dose of 500mg/kg body weight oral dose in mice and showed 65.92 and 82.18% pheriperal analgesic activity at 15 and 30mg/kg body weight doses. Central antinociceptive activity of the compound was 53.13 and 64.44% at 15 and 30mg/kg body weight respectively
