Applications of Electrochemistry at the ITIES in Drug Discovery and Development - A Review

The field of electrochemistry at the interface between two immiscible electrolyte solutions (ITIES) has been continuously expanding over the years due to their vast number of applications, including to investigate the partitioning of ionizable drugs at liquid-liquid systems. The aim of this Review is to highlight the great potential of ITIES as simple model of biological membranes to gather information on drug partition, lipophilicity, and pharmacokinetics that can be very useful for researchers in the field of drug discovery for development of new drugs with enhanced permeability. Relevant contributions and perspectives to improve the applicability of ITIES in partition studies were highlighted and discussed. The second part of this Review pretends to highlight the application of electrochemistry at the ITIES as experimental technique to investigate interactions between small ligands, including drugs, and DNA, a topic of high research interest in pharmaceutical and biological sciences, which remains with lots of opportunities to explore. Voltammetry at Liquid-Liquid Interfaces can be a versatile tool in the field of Drug Discovery as simple model for mimicking drug permeation through biological membranes helping to understand the partition of ionizable drugs between the aqueous and organic phases while providing fundamental information on its lipophilicity that can contribute to the design of new drugs with improved biological activity. image
