A series of 2-(3,5-dimethylpyrazol-1-yl)ethylseleno derivatives has been synthesized. The glutathione peroxidase like catalytic activity of these compounds has been studied in a model system, in which reduction of hydrogen peroxide with dithiothreitol (DTTred), in the presence of an organoselenium compound was investigated by 1H NMR spectroscopy. All these compounds exhibit GPx like catalytic activities and the catalytic reaction proceeds through a selenoxide intermediate, identified by 77Se1H} NMR spectroscopy.
合成了一系列2-(3,5-二甲基吡唑-1-基)乙基硒衍生物。研究了这些化合物在模型系统中的谷胱甘肽过氧化物酶样催化活性,其中利用有机硒化合物存在下,用二硫苏糖醇(DTTred)还原过氧化氢,通过1H NMR光谱进行研究。所有这些化合物均表现出GPx样催化活性,催化反应通过一种硒氧化物中间体进行,该中间体由77Se1H} NMR光谱鉴定。
