A convenient method is proposed for the synthesis of N-unsubstituted spiroxindoles with different heterocyclic moieties (2-thiohydantoin, hydantoin, and thiazolidine) by the regio-selective 1,3-dipolar cycloaddition of azomethine ylides, generated from isatins and sarcosine, to arylidene derivatives of corresponding heterocycles. The cytotoxicity of compounds was tested by the MTT method against MCF7
提出了一种方便的方法来合成具有不同杂环部分(2-硫代乙内酰脲、乙内酰脲和噻唑烷)的 N-未取代的螺吲哚,通过由靛红和肌氨酸生成的偶氮甲碱叶立德的区域选择性 1,3-偶极环加成与亚芳基相应杂环的衍生物。化合物的细胞毒性通过 MTT 法对 MCF7、A549、HEK 和 VA13 细胞系进行测试,并与抗癌药物 Nutlin-3a 进行比较。观察到基于乙内酰脲的二螺吲哚啉酮的最佳生物活性,最具细胞毒性的化合物对 A549 肺癌细胞具有选择性,IC50 值为 6.6±1.6 μmol L-1。
