Molecular docking,PKPD, and assessment of toxicity of few chalcone analogues as EGFR inhibitor in search of anticancer agents

In the present work, molecular docking of the chalcone analogues with receptor EGFR carried out using erlotinib as reference drug is reported. About 15 chalcone analogues were analyzed CHL(1–15). Molecules CHL2, CHL3, CHL9, CHL11, and CHL15 found strong affinity for receptor EGFR exhibiting binding energies ??7.7 kcal/mol, ??7.5 kcal/mol, ??7.6 kcal/mol, ??7.9 kcal/mol, and ??8.1 kcal/mol, respectively, when erlotinib a reference drug exhibits binding energy ??7.6 kcal/mol. Toxicity for molecules was assessed against the cytochromes P450 (CYP) and P-gp using Swiss ADMET. Molecule CHL9 could be a suitable lead compound inhibitor to CYP1A2 followed by CHL2 inhibitor of CYP1A2 and CYP2C9 and CHL15 with a most stable binding affinity of ??8.1 kcal/mol, inhibiting CYP1A2, CYP2C19, and CYP2D6. CHL3 has a binding affinity of ??7.5 kcal/mol, inhibiting all the 05 CYP enzymes (CYP1A2, CYP2C19, CYP2C9, CYP2D6, and CYP3A4). CHL11 has a binding affinity of ??7.9 kcal/mol, inhibiting CYP1A2, CYP2C19, and CYP2C9. Considering inhibition of CYP family enzymes by molecules, further here we have perform the enrichment analysis to these CYP family enzymes and reported the metabolic pathways which were probably affected by inhibition of these enzymes using EnrichR online enrichment analysis server. The current predictions over these 15 chalcone derivatives will be needed to further investigate in vivo and in vitro conditions to identify the optimum therapeutic efficacy and least toxicity.
