Background/Objectives: Cancer is one of the world’s leading causes of death. In 2022 alone, 9.74 million people died of cancer. It is estimated that this figure will rise to 10.4 million by 2025. Prostate and breast cancer are the most frequently diagnosed cancers in the world. Methods: Notably, compound 9f displayed the highest activity against both prostate cancer (PC-3) and breast cancer (MCF-7) cell lines. It was seen that substitution on the coumarin ring had a positive effect on anticancer activity (except chlorine substitution at the 6th position of coumarin), while it had a negative effect on the selectivity index (the ratio of IC50 calculated for healthy and cancer cells). Conclusions: The findings are consistent with the results obtained in the Molecular Docking study. Molecular docking studies were performed to investigate the binding affinities of the synthesized compounds towards kinesin-associated motor protein EG5, Human Ribonucleotide Reductase and Human Topoisomerase II, confirming their potent in vitro cytotoxicity against cancer cell lines. In accordance with the findings of experimental studies, compound 9f demonstrated the optimal docking binding scores.
