Abstract

In order to develop spin traps with an optimal ratio between hydrophilic and lipophilic properties, low toxicity, and high stability of spin adducts (especially with superoxide radicals), several EMPO-derived spin traps have recently been synthesized forming more stable superoxide adducts (t1/2> 20min) than DMPO or DEPMPO. In this study, ESR-, 1H-, and 13C-NMR data of several phenyl-or n-pentyl-substituted EMPO derivatives are ...
