Design and synthesis of new chacones substituted with azide/triazole groups and analysis of their cytotoxicity towards HeLa cells.

A series of new chalcones substituted with azide/triazole groups were designed and synthesized, and their cytotoxic activity was evaluated in vitro against the HeLa cell line. O-Alkylation, Claisen-Schmidt condensation and Cu(I)-catalyzed cycloaddition of azides with terminal alkynes were applied in key steps. Fifteen compounds were tested against HeLa cells. Compound 8c was the most active molecule, with an IC₅₀ value of 13.03 μM, similar to the value of cisplatin (7.37 μM).
