Synthesis, Characterization and Biological Evaluation of Chalcones and Its Derivatives for Antibacterial and Anti Inflammatory Activity

Chemistry or Medicinal chemistry is a discipline at the Interchange ofchemistry and pharmacology engaged with designing, methodize andcreating drug chalcones is a conventional term given tointensifies bearing the (E)- 1,3-diphenylprop-2-en-1-one, which can befunctionlized in the propane chain by the presence of olefinic, keto as well ashydroxyl group.Chalcones are a significant class of regular items and are considered as the forerunners of flavonoids and isoflavonoids. Synthetically, is (E)-1,3-diphenylprop-2-en-1-one in which two aromatic ring rings are joined by a three carbon bond having a carbonyl moiety and and α, β unsaturation. The compounds with the backbone of chalcones have been accounted for to have different pharmacological activities for example, antimicrobial, anti- inflammatory, analgesic, anti-platelet, anti-ulcerative, antimalarial, anticancer, antiviral, anti-leishmanial, antioxidant, antitubercular, anti-hyperglycemic, immunomodulatory, inhibition of chemical mediators release, inhibition of leukotriene B4, inhibition of tyrosinase and inhibition of aldose reductase activities. This paper mainly focuses on chalcones synthesized by Claisen Schmidt condensation which involves the condensation between an aromatic aldehyde or ketone with an aliphatic ketone or aldehyde catalysed by the presence of dilute alkali or acid to form alpha beta unsaturated compound. through reviewing different biological significance of chalcones andtheir derivatives have been reported along with their antibacterial movement against, Bacillus pumilis, Bacillus subtilis (gram-positive) and Escherichia coli, Proteus vulgaris (gram-negative). The antiinflammatory action of the sixteen chalcones has been assessed byutilizing carrageenan-actuated rodent paw oedema strategy.
