Originální abstrakt

Four ferrocene derivatives - ferrocenecarboxylic acid, ferrocenium salt, ferroceneboronic acid, and amino-ferrocene - were characterized electrochemically, and their cytotoxicity was probed using cancer cells (line MG -63). We related the observed cytotoxicity with the determined redox potentials of these four ferrocenes - ami-noferrocene with its lowest redox potential exhibited the highest cytotoxicity. Thus, we synthesized four de-rivatives consisting of aminoferrocene and phenylboronic acid residue with the intent to employ them as ROS-activated prodrugs (ROS - reactive oxygen species). We characterized them and studied their time-dependent stability in aqueous environments. Then, we performed electrochemical measurements at oxidative conditions to confirm ROS-responsivity of the synthesized molecules. Finally, the cytotoxicity of the synthesized molecules was tested using cancer MG-63 cells and noncancerous NIH-3T3 cells. The experiments revealed sought behaviour, especially for para-regioisomers of synthesized ferrocenyliminoboronates.
