  An electrochemical protocol for the construction of substituted isoindolinones via reduction/amidation of 2-carboxybenzaldehydes and amines has been realized. Under metal-free and external-reductant-free electrolytic conditions, the reaction achieves the cascade formation of intermolecular C–N bonds and provides a series of isoindolinones in moderate to good yields.

  Enterovirus 71 (EV-A71) is the main causative pathogen of childhood hand, foot and mouth disease. Effective medicine is currently unavailable for the treatment of this viral disease. Using the fragment-hopping strategy, a series of 2-aryl-isoindolin-1-one compounds were designed, synthesized and investigated for their in vitro antiviral activity towards multiple EV-A71 clinical isolates (H, BrCr, Shenzhen98, Jiangsu52) in Vero cell culture in this study. The structure–activity relationship (SAR) studies identified 2-phenyl-isoindolin-1-ones as a new potent chemotype with potent antiviral activity against EV-A71. Ten out of the 24 tested compounds showed significant antiviral activity (EC50 < 10 µM) towards four EV-A71 strains. Compounds A3 and A4 exhibited broad and potent antiviral activity with the 50% effective concentration (EC50) values in the range of 1.23–1.76 μM. Moreover, the selectivity indices of A3 and A4 were significantly higher than those of the reference compound, pirodavir. The western blotting experiment indicated that the viral VP1 was significantly decreased at both the protein and RNA level in a dose-dependent manner following treatment with compound A3. Moreover, compound A3 inhibited the viral replication by acting on the virus entry stage. In summary, this study led to the discovery of 2-aryl-isoindolin-1-ones as a promising scaffold with potent anti-EV-A71 activities, which deserves further in-depth studies.

  肠道病毒71型(EV-A71)是儿童手足口病的主要病原体。目前还没有有效的药物治疗这种病毒性疾病。在本研究中，我们采用片段跳跃策略，设计、合成了一系列2-芳基-异吲哚啉-1-酮化合物，并研究了它们在Vero细胞培养中对多个EV-A71临床分离株(H、BrCr、深圳98、江苏52)的体外抗病毒活性。结构-活性关系(SAR)研究确定2-苯基-异吲哚啉-1-酮是一种对EV-A71具有强大抗病毒活性的新型有效化学型。在24个测试化合物中，有10个化合物对四种EV-A71毒株显示出显著的抗病毒活性(EC50<10µM)。化合物A3和A4表现出广泛而强大的抗病毒活性，50%有效浓度(EC50)值在1.23-1.76μM范围内。此外，A3和A4的选择性指数显著高于参照化合物皮罗达韦。western印迹实验表明，经化合物A3处理后，病毒的VP1在蛋白质和RNA水平上均显著降低，并呈剂量依赖性。此外，化合物A3通过作用于病毒进入阶段来抑制病毒复制。总的来说，本研究发现了2-芳基-异吲哚啉-1-酮作为一种具有强大抗EV-A71活性的有希望的结构，值得进一步深入研究。
