Synthesis, α-glucosidase inhibitory and molecular docking studies of prenylated and geranylated flavones, isoflavones and chalcones

Bioorg Med Chem Lett. 2015 Oct 15;25(20):4567-71. doi: 10.1016/j.bmcl.2015.08.059. Epub 2015 Aug 21.

Abstract

Three series of prenylated and/or geranylated flavonoids were synthesized and evaluated for their α-glucosidase inhibitory activity. The 3',5'-digeranylated chalcone (16) was identified as a new α-glucosidase inhibitor whose activity (IC50=0.90 μM) was 50-fold more than that of acarbose (IC50=51.32 μM). Molecular docking studies revealed the existence of strong hydrophobic interaction and H-bonding between compound 16 and α-glucosidase's active site. The inhibitory mode analysis showed that 16 exhibited a competitive inhibitory mode.

Keywords: Docking study; Flavonoid; Geranyl; Prenyl; α-Glucosidase inhibitors.
