Fig. (3) The ligand-protein interactions of compound 2a with the active site of α-amylase generated by using Discovery Studio 4.0. The (A) shows the two-dimensional interaction patterns. The legend inset represents the type of interaction between the ligand atoms and the amino acid residues of the protein. The (B) show the three-dimensional docking of the compound in the binding pocket. Dashed lines indicate the interactions between the ligand and the amino acids of the receptor.
