methylene compounds bearing a cyano group to construct biologically active pyrano[3,2-c]carbazoles. Further, all the synthesized Mannich bases were tested for their in vitro antiproliferative activity against three cancer cell lines (Hela, MDA-MB-231, and HepG2). The results indicated that these compounds showed selective cytotoxicity against Hela cells. In addition, the synthesized carbazole Mannich bases
在温和的反应条件下,由4-羟基咔唑与芳族醛和环胺反应,合成了一种新型的咔唑曼尼希碱。该方法不需要柱色谱纯化即可分离出产物。这些咔唑曼尼希碱的合成潜力可通过邻醌甲基化物的形成以及随后用具有氰基的活性亚甲基化合物进行原位捕获来构建具有生物活性的吡喃[3,2- c]来举例说明。]咔唑。此外,测试了所有合成的曼尼希碱对三种癌细胞系(Hela,MDA-MB-231和HepG2)的体外抗增殖活性。结果表明这些化合物显示出对Hela细胞的选择性细胞毒性。另外,还对合成的咔唑曼尼希碱的2,2-二苯基-1-吡啶并肼基自由基清除活性进行了筛选,大多数化合物显示出非常好的抗氧化活性。在计算机上对合成的咔唑曼尼希碱对微管蛋白聚合物的秋水仙碱结合位点进行分子对接研究。
