This table presents the predicted binding free energy (ΔG, kcal/mol) obtained from molecular docking simulations between five shortlisted IGs proteins and six commonly used CRC chemotherapies, including Irinotecan (IRN), oxaliplatin (OXA), 5-fluorouracil (5-FU), lonsurf (trifluridine-tipiracil) (FTD-TPI), capecitabine (CAP), and leucovorin (LEU). More negative ΔG values indicate stronger predicted binding affinity. Docking results were used to comparatively rank IGs for their feasibility as potential drug carrier scaffolds and do not imply pharmacological activity or therapeutic efficacy.
