CH7233163

Docking outcomes revealed that five compounds showed better binding affinity (- 9.074 to - 9.3 kcal/mol) than both reference drug CH7233163 (- 6.11 kcal/mol) and co-crystallized ligand Osimertinib (- 8.07 kcal/mol). Compared to the reference ligand, it also demonstrated conserved H-bond interactions with the residues MET_793 and GLN_791 with strong interaction probability. In conclusion, we have found a potential drug with no violation of the rule of three, Lipinski's rule of five, and 26 other vital parameters having great potential in medicinal and pharmaceutical industries applications and can overcome synthetic drug issues.

Furthermore, crystal structure analysis suggested that CH7233163 is a non-covalent ATP competitive inhibitor for EGFR-Del19/T790M/C797S that utilizes multiple interactions with the EGFR's αC-helix-in conformation to achieve potent inhibitory activity and mutant selectivity. Therefore, we conclude that CH7233163 is a potentially effective therapy for osimertinib resistant patients, especially in cases of EGFR-Del19/T790M/C797S.
