摘要
为了研究红树老鼠簕Acanthus ilicifolius L.来源内生青霉Penicillium sp.GXIMD 03101的次级代谢产物,采用硅胶柱层析、凝胶柱层析及半制备高效液相色谱对大米发酵产物进行分离纯化,利用核磁共振方法鉴定化合物的结构,并对化合物1-4进行抗胰腺癌活性筛选。结果显示,从内生青霉Penicillium sp.GXIMD 03101中分离鉴定出13个化合物,分别为(+)-rugulosin A(1)、(+)-rugulosin B(2)、1,1′,3,3′,5,5′-hexahydroxy-7,7′-dimethyl[2,2′-bianthracene]-9,9′,10,10′-tetraone(3)、questin(4)、emodin(5)、questinol(6)、uridine(7)、2′-deoxythymidine(8)、5′-O-acetyl uridine(9)、ergosta-5,7,22-triene-3β-ol(10)、(3 R)-6-hydroxymellein(11)、6-hydroxy-8-methoxy-3,4-dimethylisocoumarin(12)和indole-3-acetic acid(13)。其中,化合物1对胰腺癌细胞表现出较好的细胞毒活性,其浓度为10μmol/L时对胰腺癌细胞的抑制率为75.6%。以上结果为进一步研究开发红树内生青霉来源的天然抗胰腺癌药物提供了物质基础。
In order to investigate the secondary metabolites of an endophytic fungus Penicillium sp.GXIMD 03101 from mangrove Acanthus ilicifolius L.,the rice fermentation products were isolated and purified by silica gel column chromatography,gel column chromatography and semi-preparative High Performance Liquid Chromatography(HPLC).The structures of the compounds were identified by Nuclear Magnetic Resonance(NMR).And compounds 1-4 were screened for anti-pancreatic cancer activity.The results showed that 13 compounds were isolated and identified from Penicillium sp.GXIMD 03101,which were(+)-rugulosin A(1),(+)-rugulosin B(2),1,1′,3,3′,5,5′-hexahydroxy-7,7′-dimethyl[2,2′-bianthracene]-9,9′,10,10′-tetraone(3),questin(4),emodin(5),questinol(6),uridine(7),2′-deoxythymidine(8),5′-O-acetyl uridine(9),ergosta-5,7,22-triene-3-β-ol(10),(3 R)-6-hydroxymellein(11),6-hydroxy-8-methoxy-3,4-dimethylisocoumarin(12)and indole-3-acetic acid(13).Among them,compound 1 showed good cytotoxic activity against pancreatic cancer cells,and the inhibition rate was 75.6%at the concentration of 10μmol/L.The above results provide a material basis for further research and development of natural anti-pancreatic cancer drugs derived from mangrove endophytic Penicillium.
