This study evaluated and compares the antioxidant activity of six resveratrol analogues. The analogues 4’-
Hydroxyphenyl-benzo[d]thiazole (A), p-(N,N-dimethyl)aminobenzylidene-2-aminothiophenol (B) and p-Nitrobenzylidene-
2-aminothiophenol (C) were synthesized and the antioxidant activity was evaluated using the DPPH method. A descriptive
statistical analysis and ANOVA followed by the Tukey test, with the aid of software. The best antioxidant activity
was demonstrated by compound C (half maximal inhibitory concentration (IC50) = 18.45µM), this compound is two times
more active than resveratrol (IC50= 37.28µM). Taken together, the data presented herein suggest that these molecules
might serve as potential antioxidant considering that molecular modification is an effective strategy. As such, the compounds
described herein can serve as prototypes for further research and the development of novel antioxidant agents.
本研究评估并比较了六种白藜芦醇类似物的抗氧化活性。研究人员合成了 4'- 羟基苯基-苯并[d]噻唑(A)、对-(N,N-二甲基)氨基亚苄基-2-氨基苯硫酚(B)和对-硝基亚苄基-2-氨基苯硫酚(C)等类似物,并采用 DPPH 法评估了它们的抗氧化活性。借助软件进行了描述性统计分析和方差分析,然后进行了 Tukey 检验。化合物 C 的抗氧化活性最佳(半最大抑制浓度 (IC50) = 18.45µM),该化合物的活性是白藜芦醇(IC50= 37.28µM)的两倍。综上所述,本文提供的数据表明,考虑到分子修饰是一种有效的策略,这些分子可作为潜在的抗氧化剂。因此,本文所述化合物可作为进一步研究和开发新型抗氧化剂的原型。
