已知硝酰基自由基电化学氧化硫醇以及醇和胺。本文对巯基与具有双环结构的高活性化合物9-氮杂双环[3.3.1]壬烷N-氧基(ABNO)、2-氮杂金刚烷N-氧基(AZADO)和降托品N-氧基(NNO)的电化学反应进行了初步研究,并与典型的硝酰基自由基化合物2,2,6,6-四甲基哌啶N-氧基(克里思)。以巯基丙磺酸(MPS)为模型化合物,研究了其在水溶液中的电化学响应。此外,还对生物巯基分子谷胱甘肽进行了电化学检测。图形摘要
Nitroxyl radicals are known to electrochemically oxidize thiols as well as alcohols and amines. In this study, a preliminary investigation of the electrochemical reaction of thiols with 9-azabicyclo[3.3.1]nonaneN-oxyl (ABNO), 2-azaadamantaneN-oxyl (AZADO), and nortropineN-oxyl (NNO), which are highly active due to their bicyclo structures, for use in electrochemical analysis was performed and the results were compared with those for a typical nitroxyl radical compound, 2,2,6,6-tetramethylpiperidineN-oxyl (TEMPO). Mercaptopropane sulfonic acid (MPS) was used as a model compound to investigate the electrochemical response in aqueous solution. In addition, electrochemical detection of glutathione, a biological thiol molecule, was performed.Graphical Abstract
