Electrochemically Activated Chemotherapy
Electrochemically activated chemotherapy (EAC) is two things:
-
A natural philosophy school of biomimetic pharmaceutical design; and or,
-
A type of patented medical treatment that uses a chemotherapeutic galvanostat/potentiostat (CGP) to activate prodrugs and or precursor molecules.
EAC is biomimetic and the only technique that uses electrochemistry as a mechanism of prodrug activation.
EAC is sometimes also referred to as electroactivated chemotherapy, artificial bioactivation, or electrodrugs.
​
EAC can use any type of redox reactive precursor molecule including antibodies, proteins, small molecules, inorganic molecules and ions, and DNA and RNA.
​​
The proof-of-concept work for EAC was first performed experimentally in July 2011 using acetaminophen, a graphite anode, a flow-through electrochemical cell (Figure 1), and a mouse mammary epithelial-mesenchymal transition 6 (EMT-6) ductal adenocarcinoma cell line by Jordache Boudreau at The University Of Guelph, Guelph, Ontario, Canada.

​
Using a CGP, individuals and teams are able to develop and test redox sensitive drugs for further market development, going so far as to design electro-reactive chaperone leaving groups to active molecules, as with the case of cyclophosphamide, a World Health Organization anti-cancer molecule in-use since the 1960s.
