摘要(Abstract):

为了研究广藿香内生真菌Cerrena sp.A593的次级代谢产物及其细胞毒活性,采用正、反相硅胶柱、Sephadex LH-20凝胶柱、HPLC等色谱方法从菌株A593发酵液中分离得到8个倍半萜类化合物,经波谱数据分析,分别鉴定为chloriolin B(1),chloriolin C(2),pleurocybellone A(3),dihydrohypnophilin(4),cucumin F(5),antrodin A(6),10α-hydroxyamorphan-4-en-3-one(7),connatusin A(8),所有化合物均为首次从Cerrena属真菌中分离得到。体外细胞毒活性结果显示:化合物1~3对Hep G-2,SF-268,MCF-7,NCI-H460 4种肿瘤细胞株具有抑制活性,其IC50在20.33~63.13μmol·L~(-1)。
The secondary metabolites of endophytic fungus Cerrena sp. A593 from Pogostemon cablin and their cytotoxic activities were investigated. Eight sesquiterpenoids were isolated from the fermentation broth of the strain A593 by silica gel,reverse phase silica gel,Sephadex LH-20,HPLC and so on. Their structures were identified as chloriolin B(1),chloriolin C(2),pleurocybellone A(3),dihydrohypnophilin(4),cucumin F(5),antrodin A(6),10α-hydroxyamorphan-4-en-3-one(7),and connatusin A(8). Compounds1-8 were firstly found from the genus Cerrena. All isolated sesquiterpenoids were evaluated for in vitro cytotoxic activities against Hep G-2,SF-268,MCF-7 and NCI-H460 tumor cell lines. Compounds 1-3 showed inhibitory activities against the four tumor cell lines with IC50 values ranging from 20. 33 to 63. 13 μmol·L~(-1).
