Mechanism of one-electron oxidation of metformin in aqueous solution.

Abstract : Hydroxyl free radical-induced oxidation of metformin was studied in aqueous solution as a function of the pH. Hydroxyl free radicals were generated by gamma radiolysis of water and the oxidation end-products were quantified by high-performance liquid chromatography coupled to mass spectrometry (HPLC/MS), as a function of the radiation dose. This work is a joint experimental and theoretical (DFT) approach that has paved the way towards a comprehensive rationalization of the one-electron mechanisms of MTF oxidation, as a function of the pH.
