Graphical Abstract:


Background: Aurones, (Z)-2-benzylidenebenzofuran-3-one derivatives, are naturallyoccurring structural isomers of flavones, with promising pharmacological potential.

Methods: In this study, the structural requirements for the inhibition of porcine pancreatic α- amylase by hydroxylated or methoxylated aurone derivatives were investigated by assessing their in vitro biological activities against porcine pancreatic α-amylase.

Results: The structure-activity relationship of these inhibitors based on both in vitro and in silico findings showed that the hydrogen bonds between the OH groups of the A or B ring of (Z)- benzylidenebenzofuran-3-one derivatives and the catalytic residues of the binding site are crucial for their inhibitory activities.

Conclusion: It seems that the OH groups in aurones inhibit α-amylase in a manner similar to that of OH groups in flavones and flavonols.

Keywords: α-amylase, aurones, (Z)-2-arylidenebenzofuran-3-ones, isomers, methoxylated, flavonols.
