This study used an in-silico approach to evaluate Cannabis sativa compounds as inhibitors of the EGFR kinase domain. Among the compounds investigated, Luteolin-7 -O- glucoside, grossamide, and quercetin were the leading ATP-competitive inhibitors, with binding affinities of -10.878, -10.091, and - 10.000 kcal/mol, respectively. A four-feature pharmacophore model was generated from the lead compounds, which also showed favourable predicted pharmacokinetic profiles. During 100-ns molecular dynamics simulations (MDS), the EGFR-quercetin complex exhibited the lowest root mean square deviation of 0.9-1.5 Å, while fluctuation profiles revealed a relatively stable ligand-bound complex compared with the apo-EGFR. The MDS trajectory Molecular Mechanics/Generalized Born Surface Area analysis yielded binding free energies of -75.59 kcal/mol for grossamide, -56.90 kcal/mol for isovitexin, -49.11 kcal/mol for luteolin-7 -O- glucoside, and - 43.27 kcal/mol for quercetin, compared with - 47.41 kcal/mol for gefitinib. Electronic profiling revealed favourable orbital overlap and softness for quercetin and flavone glycosides within EGFR, while isovitexin showed superior kinetic stability and balanced solvation, supporting strong binding and active-site entry. These findings identify luteolin-7 -O- glucoside, grossamide, and quercetin as promising EGFR inhibitors and provide a baseline hypothesis for experimental validation.PMID:42999331 | PMC:PMC13742794 | DOI:10.21203/rs.3.rs-11024152/v1
