摘要:目的从三列凹硬藻Laurenciatristicha中寻找具有多样性结构的倍半萜化学成分,供药理活性筛选。方法
采用凝胶柱色谱、硅胶柱色谱、重结晶和高效液相色谱等方法进行分离;借助包括一维和二维NMR等波谱方法和
x一单晶衍射鉴定化合物的结构;用MTT法对得到的化合物进行细胞毒活性评价。结果分离得到5十倍半萜类
化合物,分别鉴定为海兔阿普里素(aplysin,I)、海兔阿普里醇(aplysinol,Ⅱ)、去滨海兔阿普里醇(debro—
moaplysinol,Ⅱ)、凹顶藻联苯(1aurebiphenyl,IV)、约翰斯顿醇(johnstonol,V);在人肿瘤细胞株HCT8、Bel一7402、
BGc一823、A549和HeLa模型上.化合物Ⅳ对所有细胞株均显示毒性,化合物Ⅲ对HeLa细胞显示中等强度的细胞
毒活性,其他化合物对所有细胞株均无明显毒性,IC”均大于10.0pg/mL。结论化合物I~V均为首次从三列凹
顶藻中得到,化台物Ⅲ对HeLa细胞具有中等强度的选择性细胞毒活性,化合物N对所有细胞株均显示毒性。
