目的對采自南中國海海域的群海綿(Agelasmauritiana)的化學(xué)成分進(jìn)行研究。方法采用硅膠色譜柱、Sephadex LH-20凝膠色譜柱、高效液相色譜等色譜方法,對Agelasmauritiana正丁醇萃取物進(jìn)行分離純化;應(yīng)用現(xiàn)代波譜技術(shù)對化合物進(jìn)行化學(xué)結(jié)構(gòu)鑒定;用M TT法對化合物進(jìn)行體外人肺癌細(xì)胞株A549細(xì)胞生長抑制活性測試。結(jié)果共分離得到8個化合物,分別鑒定為: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)。體外活性篩選中,這些化合物對A549顯示出不同程度的生長抑制活性,化合物1~3的活性與陽性對照阿霉素相近。結(jié)論化合物1、2、4、5、6、8為首次從該種海綿中分離得到。首次選用A549對化合物1~7的活性進(jìn)行評價,化合物2、3的顯著生長抑制活性為進(jìn)一步深入研究提供了依據(jù)。

群海綿(Agelasmauritiana)的化學(xué)成分研究起始于20世紀(jì)70年代,代謝產(chǎn)物主要包括二萜類生物堿、溴吡咯類生物堿、類胡蘿卜素等,這些化合物在體外篩選中表現(xiàn)出抗污損、細(xì)胞毒性及抗微生物等活性[1,5,7,9]。本研究采用體外細(xì)胞毒活性追蹤分離方法,對采自中國西沙群海綿A.mauritiana的正丁醇萃取部分的化學(xué)成分進(jìn)行了研究,分離得到8個化合物,包括7個二萜生物堿(1~7)及一個二肽化合物aurantiamide acetate(8);并運用核磁共振、質(zhì)譜等現(xiàn)代波譜技術(shù)結(jié)合文獻(xiàn)報道對這些化合物的結(jié)構(gòu)進(jìn)行了化學(xué)結(jié)構(gòu)鑒定(圖1)。

4 討論

從群海綿中共分離得到兩類化合物,包括7個二萜生物堿(1~7)及一個二肽aurantiam ide acetate(8)。除化合物3和7以外,其余化合物均為首次從該種海綿中分離得到。二肽aurantiamide acetate(8)曾從多種中草藥植物中分離得到,在海綿中,僅在Sigmadocia cym iform ls Esper中曾有報道[12,13,15]。本次報道是第二次從海綿中發(fā)現(xiàn)該化合物。有意思的是化合物(-)ageloxime D(7)在氘代甲醇中由于次黃嘌呤上肟基與鄰位氮原子間質(zhì)子轉(zhuǎn)移產(chǎn)生的結(jié)構(gòu)互變,導(dǎo)致其13C NMR譜圖中部分碳信號會裂分成兩組不同的信號[16]。

在體外細(xì)胞毒性測試中,這些化合物對人肺腺癌細(xì)胞株A549顯示出不同程度的生長抑制活性,化合物2、3的活性與陽性對照阿霉素相近(表1)。這是首次選用A549細(xì)胞株對化合物1~7進(jìn)行生物活性測試。這些化合物對腫瘤細(xì)胞株A549顯著的生長抑制活性為其進(jìn)一步深入研究提供了依據(jù)?!緟⒖嘉墨I(xiàn)】

ObjectiveTo investigate the chem ical constituents of marine sponge Agelasmauritiana collected from the South China Sea.MethodsThe n-butanol extract ofmarine sponge Agelasmauritiana was separated and purified by repeated column chromatography on silica gel,Sephadex LH-20,and reversed-phase high-performance liquid chromatography(RPHPLC).The chemical structures of those obtained compoundswere determined on the basis of spectroscopic analysis and comparison with reported data.The tumor cell grow th inhibitory activity of these compounds towards human lung carcinoma cells A549 was tested.ResultsEight 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 aurantiam ide acetate(8).These compounds displayed different level of tumor cell grow th inhibitory activity towards cell A 549 in vitro.Compounds1-3 showed significantactivity towards cell A 549,being similar to thatof the positive controlof adriamycin.ConclusionCompounds1,2,4,5,6,8 were isolated for the first time from the sponge Agelasmauritiana.Cell A549 was selected for the first time for the activity evaluation of compounds 1~7.Significant inhibition activity of compounds 2、3may hold as a basis for further research.
