Abstract

Objective: To investigate the interactions between select flavonoids (Luteolin, Quercetin, Apigenin, Kaempferol, and Amorphine) and the CXCR3 receptor, evaluating their potential as novel therapeutic agents in cancer immunotherapy.

Methods: Molecular docking simulations were employed to analyze flavonoid-CXCR3 receptor interactions. Comprehensive in silico ADMET analyses were conducted to assess pharmacokinetic properties and toxicity profiles of the compounds.

Results: Flavonoids exhibited high-affinity binding to the CXCR3 receptor, with binding affinities ranging from -8.7 to -13.0 kcal/mol. Amorphine demonstrated the highest binding affinity (-13.0 kcal/mol), indicating superior inhibition potential. Luteolin showed optimal ADME characteristics, including favorable oral bioavailability (62%) and blood-brain barrier permeability (log BB -1.911). Molecular docking analyses identified critical amino acid residues (TYR205, TYR308, TRP109, PHE131, and ASN132) in flavonoid-CXCR3 interactions. In silico toxicity predictions suggested low risk profiles for all examined flavonoids.

Conclusion: This study provides evidence for the potential of flavonoids as CXCR3 receptor antagonists in cancer immunotherapy. The elucidated molecular interactions and favorable ADMET profiles warrant further investigation of these compounds. Future research should focus on optimization of flavonoid-based CXCR3 inhibitors, preclinical and clinical evaluations, and assessment of their immunomodulatory effects within the tumor microenvironment. These findings contribute to the development of novel, flavonoid-derived therapeutic strategies in cancer treatment.
