Abstract

Spectroscopic technique coupled with electrochemical oxidation has been used to study the redox-mechanism of 6-mercaptopurine. Electrochemical oxidation of 6-mercaptopurine has been studied in the pH range 2.0-10.0 by linear and cyclic sweep voltammetry, coulometry and constant potential electrolysis. Spectroscopic technique has been used to monitor the clevage of the S-S bond in the UV-absorbing intermediate generated during electrooxidation. The decay has been observed in a pseudo first order reaction. The ultimate products of oxidation in controlled potential electrolysis have been found as 6-mercaptopurine and purine-6-sulfinic acid. Tentative mechanisms for the formation of the products have also been suggested. It is concluded that spectroscopic studiescoupled with electrochemical studies provide a uniquely invaluable insight into the redox mechanism of biologically significant molecules.
