Figure 5a.

Molecular docking (two-dimensional images) of cyclin D1/Cdk4 inhibitor and polyphenols (identified by high-performance liquid chromatography) of methanol extract of wheatgrass with cyclin D1 (Protein Data Bank ID (PDB ID): 2W96). Docking pose of (a) cyclin D1/Cdk4 inhibitor (2-Bromo-12, 13-dihydro-5H-indolo[2, 3-a] pyrrolo[3, 4-c] carbazole-5, 7 (6H)-dione) (b) Rutin (c) Quercetin (d) Gallic acid (e) Caffeic acid and (f) Ferulic acid. Green lines show π-π interactions and pink lines show H-bond interactions with the arrow head pointing the acceptor atom
