Nine new compounds, including five natural rarely-occurring 2, 3-dihydro-1H-indene derivatives named diaporindenes E-I (1-5), and four new benzophenone analogues named tenellones J-M (6-9) were isolated from the deep-sea sediment-derived fungus Phomopsis lithocarpus FS508. All the structures for these new compounds were fully characterized on the basis of spectroscopic data, NMR spectra, and ECD calculation and single-crystal X-ray diffraction analysis. The potential anti-tumor activities of compounds 1-9 against four tumor cell lines SF-268, MCF-7, HepG-2, and A549 were evaluated using the SRB method. Compound 7 exhibited cytotoxic activity against the SF-268 cell line with an IC value of 11.36 μmol·L.
从深海沉积物来源的真菌 Phomopsis lithocarpus FS508 中分离得到了九个新化合物，包括五个天然罕见的 2,3-二氢-1H-茚衍生物，命名为 diaporindenes E-I（1-5），以及四个新的二苯甲酮类似物，命名为 tenellones J-M（6-9）。基于光谱数据、NMR 谱、ECD 计算和单晶 X 射线衍射分析，对所有这些新化合物的结构进行了全面表征。采用 SRB 法评价了化合物 1-9 对 SF-268、MCF-7、HepG-2 和 A549 四种肿瘤细胞系的潜在抗肿瘤活性。化合物 7 对 SF-268 细胞系表现出细胞毒性，IC 值为 11.36 μmol·L。
