• Antioxidative Properties of Probucol Estimated by the Reactivity with Superoxide and by Electrochemical Oxidation.
  作者：Tetsuya ARAKI、Hiroaki KITAOKA

  DOI：10.1248/cpb.49.943

  日期：——

  superoxide (O2(*-)) was investigated in acetonitrile using both electron spin resonance (ESR) and electrochemical techniques. The formation of phenoxyl radical was observed during the reaction of probucol with O2(*-) by ESR spectroscopy. The reaction of probucol with O2(*-) in acetonitrile was followed by cyclic voltammetry. With the addition of probucol, the oxidation peak current of O2(*-) decreased concentration

  使用电子自旋共振（ESR）和电化学技术研究了丙丁酚与超氧化物（O2（*-））在乙腈中的反应。通过ESR光谱观察到普罗布考与O2（*-）反应过程中苯氧基自由基的形成。普罗布考尔与O2（*-）在乙腈中的反应通过循环伏安法进行。随着普罗布考的加入，O2（*-）的氧化峰值电流依赖地降低浓度。这表明普罗布考与O2（*-）反应，即普罗布考清除乙腈中的O2（*-）。2,6-二叔丁基对苯醌被认为是普罗布考尔与乙腈中O2（*-）反应的主要产物。还进行了普罗布考的电化学氧化。普罗布考在ca给出一个不可逆的氧化峰。+1.4 V相对于 循环伏安图中的饱和甘汞电极。在分隔的电池中，在+1.2 V进行控制电位的电解。2,6-二叔丁基对苯醌，4,4'-二硫代双（2,6-二叔丁基苯酚）和4,4'-三硫代双（2,6-二叔丁基苯酚）被鉴定为阳极氧化的产物。普罗布考的这些氧化还原特性可能与生理活性相关。
