Type 2 diabetes (T2D) is characterized by impaired insulin secretion and peripheral insulin resistance. Despite many classes of drugs available, T2D is still projected to increase by 55% in 2035. Citrus fruit-derived flavonoid, naringenin has been reported to have antidyslipidemic, anti-oxidant and more recently metformin-like antidiabetic effects. Metformin, the most commonly used drug for T2D management acts by activating adenosine monophosphate activated protein kinase (AMPK). Naringeninâ??s anti-diabetic effects could be mediated by AMPK activation. Although naringenin has been shown to have anti-diabetic properties, it is less lipophilic and has poor water solubility hence chalco-naringenin analogs with enhanced pharmacological activities were synthesized. A series of 11 compounds of 4-[(cyclopropylcarbonyl) amino] chalco-naringenin analogues were synthesized using Claisen-Schmidt and characterized by IR, 1H-NMR and 13 C-NMR. An intermediate compound, N-(3-acetylphenyl) cyclopropanecarboxamide synthesized was reacted with commercially available aldehydes to yield the final amino-chalco-naringenin series. The synthesized compounds showed characteristic peaks on IR, 1H-NMR and 13 C-NMR and fit very well in the hydrophobic binding pockets of AMPK. They also presented good binding affinity to the enzyme as shown by computer simulation suggesting potential metforminlike antidiabetic effects. Further, in vitro and in vivo antidiabetic studies are suggested to elucidate the molecular mechanisms of these compounds.
