Tyrosine kinase inhibitors (TKI)-resistant mutation in epidermal growth factor receptor’s (EGFR) kinase domain is an important anomaly to look into. Studying the mutations at atomic level using molecular dynamics simulations gave us an insight into the architectural changes happening at the microscopic level. The knowledge was used to design new TKI whose function is devoid of the affect of the mutations in kinase domain. Traditional Chinese medicinal library was used for structure-based drug designing, where virtual screening was followed by ADME/Tox analysis and the shortlisted compounds were docked into the kinase domain of EGFR and simulated there using atomic-level selection of the grid. The shortlisted compounds from molecular docking analysis were subjected to MM-PBSA calculations. The in silico data generated is giving a strong lead compound for further in vitro and in vivo analysis.
