摘要:

为探究东京银背藤(Argyreia pierreana)的化学成分及其细胞毒活性,该研究采用硅胶、Sephadex LH-20、C₁₈中低压等柱色谱和半制备高效液相色谱等色谱分离手段进行分离纯化,通过理化性质、波谱数据结合参考文献鉴定化合物结构,并采用MTS法测定单体化合物对肿瘤细胞增殖的抑制活性。结果表明:(1)分离得到12个化合物,分别鉴定为argypierin A(1)、4'-羟基-5,7-二甲氧基-6-(3-甲基-丁烯基)-异黄酮(2)、2-羟基-3-甲基蒽醌(3)、rubiadin(4)、rubiadin-1-methyl ether(5)、克罗酰胺(6)、methyl 1,4-di-O-caffeoylquinate(7)、3,4-二-O-咖啡酰基奎宁酸甲酯(8)、3,5-二-O-咖啡酰基奎宁酸甲酯(9)、3,5-二-O-咖啡酰基奎宁酸乙酯(10)、ω-hydroxypropioguaiacone(11)、C-藜芦酰乙二醇(12)。其中,化合物1为新化合物,化合物2-7、10-12为首次从该植物中分离得到,化合物2-7、11、12为首次从银背藤属植物中分离得到。(2)细胞毒活性评价结果显示,化合物6对白血病HL-60、乳腺癌MDA-MB-231、结肠癌SW480肿瘤细胞株具有较好的增殖抑制活性,其IC₅₀值分别为(10.89±0.37)、(16.37±1.13)、(17.35±0.44)μmol·L^-1。

Abstract:

To study the chemical constituents from Argyreia pierreana and their cytotoxic activities, the compounds were isolated and purified using methods including silica gel, Sephadex LH-20, C₁₈ medium and low pressure column chromatography and semi-preparative HPLC. The structures of the compounds were identified through a combination method of physicochemical properties, spectral data and compared with literature references. The isolated compounds were tested for their proliferation inhibition effects on tumour cells using MTS method. The results were as follows:(1)Twelve compounds were isolated from the A. pierreana and identified as argypierin A(1), 4'-hydroxy-5,7-dimethoxy-6-(3-methyl-butenyl)-isoflavone(2), 2-hydroxy-3-methyl anthraquinone(3), rubiadin(4), rubiadin-1-methyl ether(5), grossamide(6), methyl 1,4-di-O-caffeoylquinate(7), 3,4-di-O-caffeoyl quinic acid methyl ester(8), 3,5-di-O-caffeoyl quinic acid methyl ester(9), 3,5-di-O-caffeoyl quinic ethyl ester(10), ω-hydroxypropioguaiacone(11), C-veratrylglycol(12). Among them, Compound 1 was a new compound. Compounds 2-7, 10-12 were isolated from A. pierreana for the first time. Compounds 2-7, 11, 12 were isolated from the genus of Argyreia for the first time.(2)The results of cytotoxic activity evaluation showed Compound 6 had good cytotoxic activities against leukemia HL-60, breast cancer MDA-MB-231 and colon cancer SW480 tumor cell lines with IC₅₀ values of(10.89±0.37),(16.37±1.13),(17.35±0.44)μmol·L^-1, respectively.
