protect the organism against cellular damage caused by oxidative stress. In this context, organotellurides have been described as promising antioxidant agents for decades. Herein, a series of N-functionalized organotellurium compounds has been tested as antioxidant and presented remarkable activities by three different in vitro chemical assays. They were able to reduce DPPH radical with IC50 values
抗氧化剂的使用是保护有机体免受氧化应激引起的细胞损害的最有效手段。在这种情况下,有机碲化物已被描述为有前途的抗氧化剂数十年。在本文中,一系列的N-官能化有机碲化合物已作为抗氧化剂进行了测试,并通过三种不同的体外化学分析方法显示出显着的活性。他们能够减少DPPH自由基与IC 50个值范围为5.08至19.20微克毫升-1,和它们中的一些也减少ABTS +自由基和TPTZ -铁3+在ABTS复杂+和FRAP测定法,分别。初始结构-活性关系揭示了N-取代基强烈影响所研究化合物的活性和细胞毒性。此外,已经将N-官能化有机碲化物的自由基清除活性与其硒化同类物的自由基清除活性进行了比较,表明碲原子的存在在抗氧化活性中具有重要作用。
