摘要:

利用溶剂分步萃取、Sephadex LH-20凝胶柱层析、硅胶柱层析、HPLC等多种柱色谱手段对中国南海杯叶海绵Phyllospongia sp.化学成分分离;通过多种现代波谱学手段结合文献对照,鉴定所分离化合物的结构。从其石油醚和二氯甲烷萃取部位分离鉴定了8个甾体类化合物:cholesta-5,7-dien-3β-ol(1)、ergosta-5,7,24(28)-trien-3β-ol(2)、ergosta-5,7-dien-3β-ol(3)、(24E)-stigmasta-5,7,24(28)-trien-3β-ol(4)、stigmasta-5,7-dien-3β-ol(5)、5α,6α-epoxystigmasta-7,22-dien-3β-ol(6)、5α,6α-epoxycholest-7,22-dien-3β-ol(7)、5α,6α-epoxycholest-7-en-3β-ol(8),化合物1~8为首次从该属海绵分离。测试了所有化合物对人乳腺癌细胞MCF-7、人结肠癌细胞HT-29和人喉癌上皮细胞Hep-2的细胞毒活性,其中化合物127对MCF-7人乳腺癌细胞的细胞毒活性显著,IC50分别为8.8、10.3和3.9 μmol/L。

Abstract:

A series of column chromatography methods including solvent extraction,Sephadex LH-20 column chromatography,silica column chromatography and HPLC methods were used to isolate and refine compounds from sponge Phyllospongia sp. from the South China Sea.The structures were identified by spectroscopic analysis and comparison with the literature.From the petroleum ether and dichloromethane soluble extract of Phyllospongia sp.,eight steroids were isolated for the first time and their structures were determined as cholesta-5,7-dien-3β-ol(1),ergosta-5,7,24(28)-trien-3β-ol(2),ergosta-5,7-dien-3β-ol(3),(24E)-stigmasta-5,7,24(28)-trien-3β-ol(4),stigmasta-5,7-dien-3β-ol(5),5α,6α-epoxystigmasta-7,22-dien-3β-ol(6),5α,6α-epoxycholest-7,22-dien-3β-ol(7),5α,6α-epoxycholest-7-en-3β-ol(8.The cytotoxic activity of all compounds against MCF-7 human breast cancer cells,HT-29 human colon cancer cells and HEP-2 human laryngeal cancer cells were tested.Compounds 1,2,7 and 8 showed significant cytotoxic activity against MCF-7 human breast cancer cells with IC50 values of 8.8,10.3,and 3.9 μmol/L respectively.
