| Summary: | We have recently reported SAR data describing the pharmacological activity of a series of phenyl alkyl selenides and tellurides which catalyse the oxidation of thiols by hydrogen peroxide (H2O2), “The design of redox active thiol peroxidase mimics: dihydrolipoic acid recognition correlates with cytotoxicity and prooxidant action” B. Zadehvakili, S.M. McNeill, J.P. Fawcett, G.I. Giles (2016) [1]. This thiol peroxidase (TPx) activity is potentially useful for a number of therapeutic applications, as it can alter the outcome of oxidative stress related pathologies and modify redox signalling. This article presents data describing the molecular changes that occur to a TPx mimic upon exposure to H2O2, and then the thiol mercaptoethanol, as characterised by UV–vis spectroscopy and HPLC retention time.
