Résumé In this study, a series of 3-ethyl-3-hydroxy-indole-2-ones were synthesized through the addition reaction of Et2Zn and N-substituted isatin by an autocatalytic process. The synthesized compounds were characterized by NMR spectroscopy and mass spectrometry, and the reaction mechanism was discussed. The antitumor and neuroprotection activities of these compounds were evaluated. The results showed that several compounds display protection activity on H2O2-induced apoptosis of PC12 cells, which are more effective than that of (±)-α-tocopherol Vitamin E (VE). Moreover, these compounds also show antitumor activity against A549 and P388 cell lines.
摘要 本研究通过Et2Zn与N-取代靛红的加成反应,在自催化过程中合成了一系列3-乙基-3-羟基-吲哚-2-酮。通过核磁共振波谱和质谱对合成的化合物进行了表征,并讨论了反应机理。对这些化合物的抗肿瘤和神经保护活性进行了评估。结果表明,几种化合物对 H2O2 诱导的 PC12 细胞凋亡具有保护活性,其效果优于(±)-α-生育酚维生素 E(VE)。此外,这些化合物还显示出对 A549 和 P388 细胞株的抗肿瘤活性。
