ABSTRACT
Aim: To synthesize new hybrid cinnamic acids (10a, 10b and 11) and ester derivatives (7, 8 and 9) and investigate their anti-breast cancer activities. Materials & methods: Compounds 7-11 were evaluated (in vitro) for their cytotoxic activities against the MCF-7 cell line. A flow cytometry examination was performed. Protein levels of nuclear factor erythroid 2-related factor 2 (Nrf2), topoisomerase II and caspase-9 were measured by qRT-PCR. Molecular docking studies were conducted. Results: Several components were discovered to be active, mainly component 11, which induced arrest in the cell cycle at phase S, greatly decreased the expression of Nrf2 and topoisomerase II; and upregulated the expression of caspase-9. Conclusion: The newly thiohydantoin-cinnamic acid hybrids can contribute to creating promising candidates for cancer drugs.
