assay. Compound 1g showed desirable luciferase activity in HepG2 cells without cell toxicity. mRNA and protein expression of Nrf2/ARE target genes such as NAD(P)H quinone oxidoreductase 1, hemeoxygenase-1, and glutamate-cysteine ligase catalytic subunit (GCLC) were upregulated by compound 1g in a concentration-dependent manner. Treatment with 1g resulted in increased endogenous antioxidant glutathione
设计并合成了取代的N-苯基肉桂酰胺衍生物,通过引入R 1和R 2基团,通过对迈克尔受体β位置的电子作用来确认核因子(类胡萝卜素衍生的2)样2(Nrf2)途径的活化。。使用Nrf2 /抗氧化反应元件(ARE)驱动的萤光素酶报告基因分析筛选化合物。化合物1g在HepG2细胞中显示出理想的荧光素酶活性,而没有细胞毒性。Nrf2 / ARE靶基因(如NAD(P)H醌氧化还原酶1,血红素加氧酶-1和谷氨酸半胱氨酸连接酶催化亚基(GCLC))的mRNA和蛋白表达受化合物1g浓度依赖性上调。治疗用1g导致内源性抗氧化剂谷胱甘肽增加,与谷胱甘肽合成的GCLC表达增强密切相关。此外,叔丁基过氧化氢(吨-BHP)产生的反应性氧物种显著通过除去1克,并且在细胞存活测定法的结果吨-BHP诱导的氧化细胞损伤模型显示的细胞保护作用1克在浓度依赖性方式。总之,新型化合物1g可用作抗氧化治疗中的Nrf2 / ARE活化剂。
