Seven new phenol derivatives named coleophomones E and F (, ), diorcinols L and M (, ), 1-hydroxy-6-methyl-11-methoxy-8-hydroxymethylxanthone (), porric acid E (), and 7-(2-hydroxyphenyl) butane-7,8,9-triol (), were isolated from the EtOAc extract of the marine sponge-derived fungus sp. SCSIO F46, together with 10 known compounds. Their structures were determined by spectroscopic analyses, including NMR, MS, X-ray diffraction, and theoretical calculations. Each of and contains an unusual spiro [cyclohexane-1,2'-inden] moiety, which is relatively seldom in nature products. Cytotoxic and COX-2 inhibitory activities of all purified compounds were tested and evaluated. Compound displayed obvious cytotoxicities against Huh-7, HeLa, DU145 and HL60 cells (IC values 5.7-9.6 μM) and weak activities against other five cell lines, while showed weak cytotoxicities against HeLa and HL7702 cells. Compound displayed COX-2 inhibitory activity with IC value of 3.3 μM.
从海洋海绵来源的真菌SCSIO F46的乙酸乙酯提取物中分离出七种新的酚类衍生物，分别命名为鞘脂菌素E和F（，）、二间苯二酚L和M（，）、1-羟基-6-甲基-11-甲氧基-8-羟甲基呫吨酮（）、多孔酸E（）和7-（2-羟基苯基）丁烷-7,8,9-三醇（），同时还分离出10种已知化合物。通过包括核磁共振（NMR）、质谱（MS）、X射线衍射和理论计算在内的光谱分析确定了它们的结构。和中的每一个都含有一个不寻常的螺[环己烷-1,2'-茚]部分，这在天然产物中相对较少见。对所有纯化化合物的细胞毒性和COX-2抑制活性进行了测试和评估。化合物对Huh-7、HeLa、DU1（此处原文有误，推测为DU145）和HL60细胞表现出明显的细胞毒性（IC值为5.7 - 9.6 μM），对其他五种细胞系表现出较弱的活性，而对HeLa和HL7702细胞表现出较弱的细胞毒性。化合物表现出COX-2抑制活性，IC值为3.3 μM。
