Summary: | Synthesis, characterization (HRMS, NMR, EPR, XANES, UV-Vis spectroscopy, and electrochemistry), DNA and BSA binding and
in vitro
biological screening of two new ferrocene-incorporated thiohydantoin derivatives (
5
and
6
) and their copper coordination compounds are reported. The ferrocene-based thiohydantoin derivatives were prepared by copper-catalyzed azide alkyne cycloaddition reactions between alkynyl ferrocenes and 5-(

-one. Alkynyl ferrocenes necessary for these syntheses were prepared by new procedures. Intermolecular redox reactions between the ferrocene fragment and copper(+2) coordinated ions were studied by different methods to determine the mechanism and kinetic constants of redox processes. Ferrocene-containing imidazolones (
5
and
6
) and their copper complexes were also tested for their
in vitro
cytotoxic activity against MCF-7 and A-549 carcinoma cells, and also against the noncancerous cell line Hek-293. The results showed modest cytotoxicity against the subjected cancer cell line compared with cisplatin. The ability of the obtained compounds to cause DNA degradation and cell apoptosis was investigated, and the distribution of cytosol/pellets was studied by AAS.
