OBJECTIVE: This study examined the binding affinities and therapeutic potential of natural products targeting pain-related receptors using molecular docking and molecular dynamics (MD) simulations. Drug-like properties and absorption, distribution, metabolism, excretion, and toxicity (ADMET) analyses were also conducted. METHODS: AutoDock Vina (The Scripps Research Institute, La Jolla, CA, USA) was used for docking against pain-related receptors, including transient receptor potential vanilloid 1 (TRPV1), cyclooxygenase-2 (COX-2), cannabinoid receptor 1 (CB1), mu-opioid receptor, and nicotinic acetylcholine receptors. Celecoxib was included as a reference drug for docking score comparison. Protein-ligand complex stability was assessed via 100-nanosecond (ns) MD simulations using GROMACS (GROningen MAchine for Chemical Simulations; the University of Groningen, Netherlands), analyzing root mean square deviation (RMSD) and radius of gyration (Rg). Drug-likeness was evaluated by Lipinski's rule of five, and ADMET analysis was performed for pharmacokinetics and toxicity profiling. RESULTS: Ginsenoside Rb1 exhibited a strong affinity for TRPV1 (-9.5 kcal/mol) and mu-opioid (-9.0 kcal/mol) receptors, suggesting its potential as a non-opioid analgesic candidate. Cyanidin 3-O-rutinoside demonstrated high binding to TRPV1 (-9.35 kcal/mol), COX-2 (-9.65 kcal/mol), and CB1 (-9.18 kcal/mol), surpassing the reference drug celecoxib (-7.22 kcal/mol) in COX-2 binding. MD simulations confirmed complex stability, with RMSD (3.0 Å) and Rg (3.0 nm) values lower than unbound proteins. Most compounds met Lipinski's criteria, indicating good oral bioavailability. ADMET analysis revealed favorable absorption and distribution with low toxicity. CONCLUSION: Ginsenoside Rb1 and cyanidin 3-O-rutinoside exhibit high binding affinity, stability, and favorable pharmacokinetic properties, supporting their potential as non-opioid analgesic candidates. Their ability to modulate pain pathways in vitro and in vivo warrants further investigation.
