sec‐ and tert‐amide substituted diselenides have been synthesised as synthetic mimics of glutathioneperoxidase (GPx), characterized, and studied for their antioxidantactivities using H2O2, Cum‐OOH, and tBuOOH as substrates and PhSH as thiol co‐substrate. The substitution at the free NH group of the amide moiety in the sec‐amide based diselenides is shown to enhance the GPx activity.
Sec 或 terts:已合成了一系列sec和tert酰胺取代的二硒化物作为谷胱甘肽过氧化物酶 (GPx) 的合成模拟物,使用 H 2 O 2、Cum-OOH 和t BuOOH 作为合成模拟物,对其抗氧化活性进行了表征和研究底物和PhSH作为硫醇共底物。显示基于仲酰胺的二硒化物中酰胺部分的游离 NH 基团的取代可增强 GPx 活性。
