利用药物设计中的生物活性基团拼接原理,设计合成了13个含吲哚的吡唑并[3,4-d]嘧啶衍生物.目标化合物均经核磁共振氢谱(1H NMR)、核磁共振碳谱(13C NMR)和高分辨质谱仪(HRMS)进行了结构确证.对4株肿瘤细胞(HeLa、MGC-803、MCF-7、BEL-7404)的体外抗增殖活性实验结果表明,目标化合物均表现出一定的抗肿瘤活性,MCF-7、MGC-803肿瘤细胞株敏感度高于HeLa和BEL-7404.其中,6-[(6-甲氧羰基吲哚-3-基)硫基]-1-苯基-吡唑并[3,4-d]嘧啶-4-酮(5m)表现出较好的体外肿瘤抑制活性,对MCF-7、MGC-80和HeLa细胞的IC50均小于30 μmol·L-1,对MCF-7的IC50值为(4.02±0.92)μmol·L-1,优于对照药物依托泊苷(10.1±0.62 μmol·L-1)和羟喜树碱(5.93±0.56 μmol·L-1).拓扑异构酶抑制实验结果表明,此类化合物对TopoII有选择性抑制活性,所有化合物对Topo II表现出不同程度抑制活性,对Topo I未表现出抑制活性.

Based on the combination principle in drug design, thirteen pyrazolo[3,4-d]pyrimidine derivatives containing indole moiety were designed and synthesized. The target compounds were confirmed by 1H NMR, 13C NMR and HRMS. Their in vitro cytotoxicity against four human cancer cell lines (HeLa、MGC-803、MCF-7、BEL-7404) has been investigated and most of the tested compounds displayed moderate antiproliferative activity. Especially, compound 5m exhibited the highest level of antiproliferative activity with an IC50 value <30 μmol·L-1 for HeLa, MGC-803 and MCF-7. IC50 value of methyl 3-((4-oxo-1-phenyl-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-yl)thio)-1H-indole-6-carboxylate (5m) to MCF-7 was (4.02±0.92) μmol·L-1, which was better than etoposide (10.1±0.62 μmol·L-1) and camptothecin (5.93±0.56 μmol·L-1). Further biological evaluation of these compounds suggested that these compounds showed selective inhibitory activity against Topo II as a possible intracellular target, and all compounds didn't show inhibitory activity against Topo I.
