Novel multitargeted antioxidants 3−6 were designed by combining the antioxidant features, namely, a benzoquinone fragment and a lipoyl function, of two multifunctional lead candidates. They were then evaluated to determine their profile against Alzheimer’s disease. They showed antioxidant activity, improved following enzymatic reduction, in mitochondria and T67 cell line. They also displayed a balanced
新颖多靶点抗氧化剂3 - 6通过组合作为抗氧化剂的功能设计,即,二多功能先导候选的苯醌片段和硫辛酰功能。然后对它们进行评估,以确定其抗阿尔茨海默氏病的特征。他们在线粒体和T67细胞系中显示出抗氧化活性,经过酶促还原后得到改善。他们还显示出对淀粉样β-聚集和乙酰胆碱酯酶的平衡抑制特性,是神经保护剂铅发现的有前途的分子。
