采用色谱技术对红树林内生真菌Phomopsis sp. ZZF08代谢产物进行分离纯化,MS、NMR、X-单晶衍射及与文献数据比对等方法确定其结构,MTT法考察其对体外人鼻咽癌细胞KB和KBv200的毒性作用。结果表明,由红树林内生真菌Phomopsis sp.ZZF08培养液中分离得到12个酰胺类化合物,经鉴定,分别为viridicatol (1)、cytochalasin H (2)、cytochalasin IV (3)、葡萄糖神经酰胺 (4)、△
The amide metabolites ofPhomopsis sp. ZZF08 from the South China Sea were isolated and purified by chromatography. Their structures were determined by MS
NMR
X-ray diffraction data and comparison with the literature data. Cytotoxicity in vitro was performed by tetrazolium (MTT) assay. Twelve amide compounds were isolated
which were viridicatol (1)
cytochalasin H (2)
cytochalasin IV (3)
glucosylceramide (4)
ceramide (5)
allantoin (6)
thymine (7)
pyridine (8)
cyclo-(Leu-Gly) (9)
cyclo- (Leu Ala) (10)
cyclo- (Phe Gly) (11)
and cyclo- (Phe-Ala) (12). Compounds 1,2,3,4 and 5 were isolated firstly from Phomopsis sp. collected from the mangrove bark of the Zhanjiang. In our cytotoxicity assays
compounds 2 and 3 exhibited strong cytotoxicity toward KB cells and KBv200 cells.
