with 6-membered aryls in the arylidene moiety were obtained predominantly as E-isomers while for some 5-membered aryls, the Z-isomers prevailed. The most active compounds inhibited NQO2 with an IC50 of 0.368 µM. The presence of a double bond in the oxindoles was crucial for NQO2 inhibition activity. There was no correlation between NQO2 inhibition activity of the synthesized compounds and their cytotoxic
NRH:quinone oxidoreductase 2 (NQO2) 酶在神经退行性疾病、疟疾、青光眼、COVID-19 和癌症等各种疾病的发病机制中起着重要作用。已知 NQO2 表达在一些癌细胞系中增加。由于 3-arylidene-2-oxindoles 广泛用于新型抗癌药物的设计,例如激酶抑制剂,因此研究此类结构是否对 NQO2 具有额外活性很有趣。在此,我们报告了 3-亚芳基-2-羟吲哚作为新型 NRH:quinone 氧化还原酶抑制剂的合成和研究。结果表明,在亚芳基部分具有 6 元芳基的羟吲哚主要以 E 异构体形式获得,而对于一些 5 元芳基,Z 异构体占优势。最活跃的化合物抑制 NQO2,IC50 为 0.368 µM。oxindoles 中双键的存在对 NQO2 抑制活性至关重要。合成化合物的 NQO2 抑制活性与其对 A549 细胞系的细胞毒性作用之间没有相关性。
