Stimuli-Responsive Cycloaurated "OFF-ON" Switchable Anion Transporters

Angew Chem Int Ed Engl. 2020 Sep 28;59(40):17614-17621. doi: 10.1002/anie.202006392. Epub 2020 Aug 11.

Abstract

Anion transporters have shown potential application as anti-cancer agents that function by disrupting homeostasis and triggering cell death. In this research article we report switchable anion transport by gold complexes of anion transporters that are "switched on" in situ in the presence of the reducing agent GSH by decomplexation of gold. GSH is found in higher concentrations in tumors than in healthy tissue and hence this approach offers a strategy to target these systems to tumors.

Keywords: anion transport; gold complexes; molecular switch; reduction kinetics; supramolecular chemistry.
