从红树林真菌拟茎点霉(Phomopsis sp.)HNY 29 - 2 B的代谢产物中分离得到3个新的phomoxanthone类化合物:phomolactonexanthones A(1),B(2)和脱乙酰phomoxanthone C(3),沿着5个已知的phomoxanthone类化合物:dicerandrol A(4),dicerandrol B(5),dicerandrol(6),脱乙酰phomoxanthone B(7)和penexanthone A(8)。化合物1-3的结构经波谱分析确定。所有化合物通过MTT测定针对包括人乳腺MDA-MB-435、人结肠HCT-116、人肺Calu-3和人肝Huh 7的四种人癌细胞系进行评估。化合物4、5、7和8对肿瘤细胞具有一定的细胞毒活性(IC_(50)< 10 μM)。
Three new phomoxanthone compounds, phomolactonexanthones A (1), B (2) and deacetylphomoxanthone C (3), along with five known phomoxanthones, including dicerandrol A (4), dicerandrol B (5), dicerandrol (6), deacetylphomoxanthone B (7) and penexanthone A (8), were isolated in the metabolites of the fungus Phomopsis sp. HNY29-2B, which was isolated from the mangrove plants. The structures of compounds 1–3 were established on the basis of spectroscopic analysis. All compounds were evaluated against four human cancer cell lines including human breast MDA-MB-435, human colon HCT-116, human lung Calu-3 and human liver Huh7 by MTT assay. The compounds 4, 5, 7 and 8 showed cyctotoxic activities against tested cancer cell lines (IC50 < 10 μM).
