In this regard, chalcones have frequently been targeted by many researchers owing to their diverse biological activities.Methods: Here, the Claisen–Schmidt condensation reaction was applied to synthesize five chalcone derivatives. The chalcone derivatives were evaluated for their relative antidiabetic activities in vivo using streptozotocin (STZ)-induced diabetic mice. Besides, the compounds were assessed for their reduction in postprandial hyperglycemia at 50 and 100 mg/kg dose levels against a standard drug, glibenclamide. In addition, the structure–activity relationship (SAR) was analyzed to determine the effect of structural modification in chalcones activity.Results: A dose-dependent reduction in postprandial hyperglycemia was observed. The highest reduction in blood glucose level (BGL) was achieved by compound 3 at a dose of 100 mg/kg (39%). This was found to be even higher than glibenclamide (34.5%). In the STZ-induced diabetic animal model, all test compounds showed comparable efficacy with glibenclamide. The SAR analysis revealed that the incorporation of electron-donating groups at position 5 of the benzaldehyde ring and position 2 of the acetophenone ring is promising to increase the antihyperglycemic activities of chalcones.Conclusion: The chalcone derivatives considered in this study could be used as potential lead compounds in the discovery of effective drugs to treat diabetes mellitus.Keywords: antidiabetic, chalcone, diabetes mellitus, structure–activity relationship, streptozotocin, characterization, in vivo
