Electrochemically Driven Supramolecular Interaction of Quinones and Ferrocifens: An Example of Redox Activation of Bioactive Compounds.

This review discusses the state of the art, challenges and perspectives in recent applications of electrochemistry in the life sciences. It deals mainly with the elucidation of molecular mechanisms of drug action, drug design and development, involving electron transfer, pharmaco-electrochemistry (the combination of electrochemical and pharmacological assays), and electrochemical studies of membrane models and drug delivery. It aims to shed light on the question: does electrochemistry really contribute to this area? It includes a general introduction for the use of electrochemistry in the life sciences, with a focus on how electrochemistry can uniquely provide both kinetic and thermodynamic information.

Molecular mechanism of action of 2-ferrocenyl-1,1-diphenylbut-1-ene on HL-60 leukemia cells.

The aim of this work was to investigate the mechanism of action of 2-ferrocenyl-1,1-diphenylbut-1-ene (1) on HL-60 human leukemia cells. While inactive against noncancerous cells, 1 provoked a concentration-dependent decrease in viable tumor cells, primarily via apoptosis, as evidenced by analysis of cell morphology, activation of caspases 3 and 7, increased DNA fragmentation, and externalization of phosphatidylserine. Necrosis was observed only at the highest tested concentration (4 μM).
