3D docking view of β-sitosterol (A), β-sitosterol-3-O-β-D-glucopyranoside (B), 20-hydroxy-ocdysone (C), and luteolin (D) in the active site of COX-2. Labeled residues that constitute the proximal (yellow), central (magenta), and distal (cyan) binding pockets and other interacting residues in the active site (gray) are depicted in line models. Ligands are represented by green stick model. Hydrogen bond (blue), π-π stacking (pink), alkyl (yellow), and carbon-hydrogen bond (green) interactions are depicted in dashed lines
