O-Allyloxy chalcone derivatives: design, synthesis, anticancer activity, network pharmacology and molecular docking

A series of (2E)-3-[2,4-bis(2-propen-1-yloxy)phenyl]-1-phenyl]-2-propen-1-ones-chalcone derivatives with O-allyloxy groups-were synthesized in good yields and characterized by different analytical techniques. Their anticancer activity was evaluated against the A549 (lung cancer) cell line. The most active compounds of this series were the 1-(4-fluorophenyl derivative 9c (IC50 = 0.48 +/- 0.07 mu M) and the 1-(4-octyloxy)phenyl derivative 9f (IC50 = 0.04 +/- 0.01 mu M). Network pharmacology analysis using the SwissTarget and DisGeNet databases identified potential targets for 9c in the Non-Small Cell Lung Carcinoma (NSCLC) cell line. Protein-Protein Interaction (PPI) network analysis revealed seven hub genes: MAPK14, PTGS2, HSP90AA1, MAPK8, NOS2, SYK, and NR3C1. Gene ontology analysis highlighted diverse biological functions. KEGG pathway analysis implicated pathways in cancer and immunoregulation. Molecular docking analysis suggested a strong interaction between 9c with MAPK14 (calculated docking score of -8.4 kcal mol(-1)). Compound 9c's potent activity warrants further preclinical and clinical evaluation as a potential NSCLC therapy Based on this results, study of heterocyclic compounds with O-allyloxy groups will help to explore their impact on anticancer activity and mechanistic pathway.
