A Docking Solution of the compound 3a (left) and 4f (right) inside the binding pocket of alpha-amylase (pdb code: 4w93) forming hydrogen bonds with the residues I235 and E233; while making and charge-π interactions with H201. Other residue like Y151 is also able to make hydrogen bonds or hydrophobic interactions. B The interaction map of the compound 3a (left) and 4f (right) inside the binding pocket of human pancreatic alpha-amylase (pdb code: 4w93) forming hydrogen bonds with the residue I235; while making and charge-π interactions with H201, and other possible HB and hydrophobic interactions with the surrounding residues
