Figure Lengend Snippet: Schematic representation of the virtual screening (VS) protocol used in this study to select novel potential h15-LOX-2 inhibitors from the ZINC-Curated database. (A) Representation of the sequence of selection filters applied to the ZINC-Curated database in each VS step. (B) Schematic representation of the steps to generate the shape-based model that was used as the first filter in the VS protocol: 1. Alignment of low energy conformation structures of two known h15-LOX-2 inhibitors ( LIT-04 and LIT-05 ), using LigandScout’s alignment algorithm, and 2. Shape-based model generation using ROCS. The molecular shape surface is represented in gray. The figure was prepared by using LigandScout and ROCS.

Figure Lengend Snippet: Score frequency distributions of the best-ranked docking poses for the compounds selected from the ZINC-Curated database after applying the docking filter. (A) ChemPLP score values distribution. (B) Goldscore score values distribution. The figure was prepared using GraphPad Prism. The ChemPLP and Goldscore score values of two h15-LOX-2 known inhibitors ( LIT-01 and LIT-05 ) are represented for comparison.

Figure Lengend Snippet: Schematic representations of the predicted binding modes (best-scored docking solutions) of the h15-LOX-2 inhibitors selected by the VS protocol proposed in this study: (A) Compound 07 ; (B) compound 10 ; (C) compound 11 ; (D) compound 12 ; (E) compound 13 ; and (F) compound 14 . The crystal structure of h15-LOX-2 (PDB code: 4NRE ; resolution: 2.63 Å) was used for all docking calculations. Left panels : Schematic representations of the best-scored docking solutions for each inhibitor inside the h15-LOX-2 active site’s cavity. For clarity, only the active site residues that interact with each inhibitor are highlighted (shown as sticks). Catalytic iron is shown as a brown sphere. A water molecule that coordinates iron and makes a hydrogen-bond interaction with compounds 10 and 12 is shown as a red sphere in panels (B, D). Central panels : Schematic representations of the best-scored docking solutions for each compound, with h15-LOX-2 active site’s cavity represented as a surface to highlight its U-shaped format. The inhibitors occupy the more solvent-exposed arm of the cavity, which corresponds to the cavity’s right arm in the protein’s orientation captured to prepare this figure. Right panels : 2D Schematic representations of the protein–ligand interactions identified using the LigandScout program. Yellow: hydrophobic interactions; blue circle/arrow: pi-cation interactions; blue cones: ionic interactions; red arrows: hydrogen-bond acceptor interactions; pink arrow: halogen bond interaction. The figure was prepared using PyMOL.
