摘要
Superoxide radical is involved in numerous physiological and pathophysiological processes. Tetrathiatriarylmethyl (TAM) radicals are known to react with superoxide allowing measurement of superoxide production in biological media. We report the synthesis of a Nitro conjugated TAM radical showing a rate constant of 7 × 105 M−1 s−1 which is two order of magnitude higher than other TAMs, allowing high sensitivity measurement of superoxide.
