中文摘要: 肿瘤转移是恶性肿瘤的主要特征,是引起癌症患者死亡的首要因素。基质金属蛋白酶参与了肿瘤细胞转移过程中的侵袭、血管发生以及细胞凋亡的调节,是研究抗肿瘤转移药物的重要靶点。经抗肿瘤活性筛选发现,维吾尔民族药新疆阿魏种子脂溶性部分对肿瘤细胞具有明显的抑制作用,所含的倍半萜-香豆精类成分具有抑制基质金属蛋白酶及血管内皮生长因子的活性,有抗肿瘤转移的作用。本研究拟在活性跟踪的基础上,采用现代层析技术和光谱技术对阿魏种子具有抗肿瘤活性的部位进行分离签定,以期能够阐明阿魏种子抗肿瘤的物质基础,发现具有高效抗肿瘤转移活性的新化合物或先导化合物。寻找其发挥抗肿瘤作用的酶或靶细胞,从分子水平研究其抗肿瘤转移作用机制,为开发研究抗肿瘤新药打下基础

英文摘要: Historically, plants were a folkloric source of medicinal agents, and as modern medicine developed, numerous useful drugs were developed from lead compounds discovered from medicinal plants. Today, this strategy remains an essential route to new pharmaceuticals. During the course of a cytotoxicity screening program on natural products, it was found that a petroleum extract of seed of Ferula sinkiangensis was active against various human cancer cell lines. Bioassay-directed fraction of the active extract of seed of F. sinkiangensis led to the isolation of active compounds, whose structures were established from spectral evidence. We anticipate to get some leading compounds and conduct a study on their antitumor mechanism of action.
