(a) Three-dimensional (3-D) docking model of the superimposed structures of the most active compound 3e with the (9Z,11E)-13(R)-hydroperoxy-9,11-octadecadienoic acid (13-HPOD) as LOX substrate. The grey color represents compound 3e, while yellow sticks represents 13-HPOD, with distance indicated in angstroms (Å); (b) Two-dimensional (2-D) diagram of binding interaction between the most active compound 3e with amino acid residues of soybean 15-LOX; (c) Two-dimensional (2-D) diagram of binding interaction between 13-HPOD with amino acid residues of soybean 15-LOX. The green color line
indicates the hydrogen bonding.
