Abstract
Abstract The electrochemical oxidation pathway of 6-thioxanthine was investigated by cyclic voltammetry, coulometry, UV—VIS spectroscopy and mass spectrometry. Experimental results show that the thio group of 6-thioxanthine oxidizes at moderate potentials, forming an unstable product. The evidence obtained indicates that the product is a dimer. At more positive potentials the thio group and the purine ring are oxidized with allantoin as the major final product. The electrochemical oxidation pathway and its biological significance are discussed.
