group exhibited the strongest ARE inductive activity in the first round structure–activity relationship (SAR) study. Biological studies showed the compound induced nuclear translocation of Nrf2 preceded by phosphorylation of ERK1/2. The data encouraged us to use 2 as lead and 20 derivatives were synthesized to discuss a more detailed SAR, leading to a more potent compound 9, which can be the starting
当暴露于亲电子试剂中时,人结肠直肠癌细胞(HCT116)通过激活NF-E2相关因子2(Nrf2)/抗氧化反应元件(ARE)途径来抵消氧化应激。为了鉴定新的激活剂,荧光素酶报告基因检测被用于筛选我们实验室的内部数据库,从而导致了新型α-吡喃酮化合物1的成功。2与2-氟苯基组表现出在第一轮的结构-活性关系(SAR)研究最强是感性的活性。生物学研究表明,化合物诱导的Nrf2核易位,然后ERK1 / 2磷酸化。数据鼓励我们使用2作为前导物,并合成20个衍生物以讨论更详细的SAR,从而得到更有效的化合物9,可以作为进一步修饰的起始化合物。
