基于药效团拼合的设计原理,以4-羟基苯乙酮为原料,通过加成、环化、取代、肼解和缩合等多步反应构建了两类含有靛红结构的吡唑衍生物,共计12个目标产物,其结构经1H NMR,13C NMR和HRMS确证.采用细胞计数试剂盒-8(CCK-8)法测试目标产物对人非小细胞肺癌细胞A549的体外抑制作用,部分化合物显示出一定的抗增殖活性,其中N'-(3-亚氨基-6-氯吲哚-2-酮)-1-苯甲基-3-(4-甲氧基苯基)-1H-吡唑-5-甲酰肼(7e)和N'-(3-亚氨基-6-溴吲哚-2-酮)-1-苯甲基-3-(4-甲氧基苯基)-1H-吡唑-5-甲酰肼(7f)的IC50值分别为30.41和29.69 μmol/L.流式细胞术检测表明,化合物7f能够剂量依赖性地诱导A549细胞凋亡,并降低线粒体膜电位,但对细胞周期没有影响.上述研究证明,目标产物7f能够通过线粒体途径诱导A549细胞凋亡,从而发挥抗肿瘤活性.

Two kinds of novel pyrazole derivatives containing isatins, total of 12 target compounds, were prepared from 4-hydroxyacetophenone via addition, cyclization, substitution, hydrazinolysis and condensation, which were characterized by 1H NMR, 13C NMR and HRMS. The anti-neoplastic activity of target molecules was evaluated against human non-small cell lung cancer cell line A549 using cell counting Kit-8 (CCK-8) assay. The data showed that several compounds possessed potential anticancer effect. Among them, N'-(3-imino-6-chloroindole-2-one)-1-benzyl-3-(4-methoxyphenyl)-1H-pyrazole-5-carbohydrazide (7e) and N'-(3-imino-6-bromoindole-2-one)-1-benzyl-3-(4-methoxyphenyl)-1H-pyrazole-5-carbohydrazide (7f) exhibited IC50 values of 30.41 and 29.69 μmol/L, respectively. Flow cytometry showed that compound 7f could induce apoptosis of A549 cells, reduce the mitochondrial membrane potential, but have no effect on the cell cycle. Those data indicated that the anti-proliferative activity of molecule 7f was mediated by apoptosis-dependent mechanism involving the mitochondrial pathway in A549 cells.
