Rational Design and Synthesis of Isatin‐Chalcone Hybrids Integrated with 1H‐1,2,3‐Triazole: Anti‐Proliferative Profiling and Molecular Docking Insights

Abstract

AbstractIn this study, a series of isatin‐chalcone linked triazoles were synthesized using Cu‐promoted Azide‐Alkyne Cycloaddition (CuAAC) reaction and evaluated for their cytotoxicity against various cancer cell lines. The most potent compound displayed approximately 2.5 times greater activity compared to both reference compounds against ovarian cancer cell lines. These findings were supported by caspase‐mediated apoptosis and molecular docking analyses. Docking revealed comparable VEGFR‐2 affinities for 5 b and 5‐FU but highlighted stronger interaction of 5 b with EGFR, evident from its lower docking score. Overall, these results signify the notable anti‐proliferative potential of most synthesized hybrids, notably emphasizing the efficacy of compound 5 b in suppressing cancer cell growth.
