Chalcones are organic compounds with numerous biotic activities such as anticancer, antibacterial, and antifungal. Using the Claisen-Schmidt condensation reaction, three methoxy substituted chalcone derivatives were synthesized and crystallized using the slow evaporation method. Cytotoxicity evaluation showed that all three compounds were almost inoffensive to VERO cell lines and exhibited excellent anticancer activity on breast cancer (MCF-7) cell lines. Molecular docking analysis confirmed that all three molecules fit well at the active site of the target protein with PDB ID: 1M17. In silico pharmacokinetic analysis reveals that the compounds satisfied Lipinski’s rule of five and can be recommended as oral drug candidates. ADMET properties of the organic synthesized compounds revealed the efficacy of the compounds to be considered as drug candidates for treating breast cancer after in-vivo experiments and clinical authentication.
