摘　　要：为了寻找高效低毒的新型抗肿瘤化合物,设计并合成了一系列新型的苦参碱缩氨基脲类化合物.采用噻唑蓝(MTT)法测定目标化合物对人肺癌细胞(A549)、人肝癌细胞(HepG2)、人宫颈癌细胞(Hela)、人胃癌细胞(MGC803)细胞株及人正常肝细胞株(L-O2)的细胞毒活性.结果表明,大多数衍生物对肿瘤细胞的细胞毒性明显高于母体化合物.其中14-甲酰基-15-氯-苦参碱缩N-(3-氯苯基)氨基脲(6c)和14-甲酰基-15-氯-苦参碱缩N-(3-硝基苯基)氨基脲(6f)对人肺癌A549细胞株表现出良好的抑制活性,IC_(50)值分别为(11.70±0.25)和(15.61±0.07)μmol/L,活性优于阳性对照药喜树碱.同时,对人胃癌MGC803细胞株IC_(50)值分别为(11.32±1.07)和(9.27±2.03)μmol/L,并且对人正常肝细胞株(L-O2)表现出较低的细胞毒性.流式细胞术及线粒体膜电位检测表明,化合物6f能够剂量依赖性地诱导MGC803细胞凋亡,并降低线粒体膜电位.上述研究为苦参碱的结构修饰提供了思路.In order to search for novel antitumor drugs with high efficiency and low toxicity,matrine semicarbazide derivatives were designed and synthesized.The antiproliferative activities of target compounds in four human cancer cell lines of A549(lung),HepG2(liver),Hela(epithelial cervical),MGC-803(gastric) and a human normal cell of L-O2(liver) were evaluated by methyl thiazolyl tetrazolium(MTT) assay.Biological screening results demonstrated that most of the derivatives exhibited more potent cytotoxicity against tumor cell lines superior to parent compound matrine.Among them,compounds of 14-formyl-15-chloro-matrine N-(3-chlorophenyl) semicarbazide(6c) and 14-formyl-15-chloro-matrine N-(3-nitrophenyl)semicarbazide(6f) displayed better antiproliferative activity with IC_(50) values of(11.70±0.25) and(15.61±0.07) μmol/L toward A549 cells compared with camptothecin,and with IC_(50) values of(11.32±1.07) and(9.27±2.03) μmol/L against MGC-803 cells.Moreover,they exhibited lower cytotoxicity against human normal liver cell line L-O2.Flow cytometry and JC-1 mitochondrial membrane potential detection showed that compound 6f could induce apoptosis of MGC803 cells and reduce the mitochondrial membrane potential.It would provide a new idea for the structural modification of matrine.
