Cyclic Voltammetry of Auranofin [PDF]

Metal-Based Drugs, 1999
The oxidative behavior of Auranofin, 2,3,4,6‐tetra‐O‐acetyl‐1‐thio‐β ‐D‐glucopyranosato‐ S(triethylphosphine)gold(I), was investigated by using cyclic voltammetry (CV) in 0.1 M Bu4NPF6/CH2Cl2 and 0.1 M Bu4NPF4/CH2Cl2 solutions using Pt working and auxiliary electrodes and a Ag/AgCI reference.
