摘  要:目的:对采自南中国海海域的群海绵(A gelas mauritiana)的化学成分进行研究。方法采用硅胶色谱柱、Sephadex L H-20凝胶色谱柱、高效液相色谱等色谱方法,对 A gelas mauritiana正丁醇萃取物进行分离纯化;应用现代波谱技术对化合物进行化学结构鉴定;用M T T法对化合物进行体外人肺癌细胞株A549细胞生长抑制活性测试。结果共分离得到8个化合物,分别鉴定为:agelasine A (1)、agelasine B (2)、epi-agelasine C (3)、(-)agelasine D (4)、agelasine E (5)、agelasine F (6)、(-)ageloxime D (7)、aurantiamide acetate (8)。体外活性筛选中,这些化合物对A549显示出不同程度的生长抑制活性,化合物1∽3的活性与阳性对照阿霉素相近。结论化合物1、2、4、5、6、8为首次从该种海绵中分离得到。首次选用A549对化合物1~7的活性进行评价,化合物2、3的显著生长抑制活性为进一步深入研究提供了依据。Objective To investigate the chemical constituents of marine sponge A gelas mauritiana collected from the South China Sea .Methods The n-butanol extract of marine sponge A gelas mauritiana was separated and purified by repeated column chromatography on silica gel ,Sephadex LH-20 ,and reversed-phase high-performance liquid chromatography (RP-HPLC) .The chemical structures of those obtained compounds were determined on the basis of spectroscopic analysis and com-parison with reported data .The tumor cell growth inhibitory activity of these compounds towards human lung carcinoma cells A549 was tested .Results Eight compounds were isolated ,including agelasine A (1) ,agelasine B (2) ,epi-agelasine C (3) , (-)agelasine D (4) ,agelasine E (5) ,agelasine F (6) ,(-)ageloxime D (7) and aurantiamide acetate (8) .These compounds dis-played different level of tumor cell growth inhibitory activity towards cell A 549 in vitro .Compounds 1-3 showed significant ac-tivity towards cell A549 ,being similar to that of the positive control of adriamycin .Conclusion Compounds 1 ,2 ,4 ,5 ,6 ,8 were isolated for the first time from the sponge A gelas mauritiana .Cell A549 was selected for the first time for the activity evalua-tion of compounds 1∽7 .Significant inhibition activity of compounds 2、3 may hold as a basis for further research .
