Three new compounds, including 6-methoxy-3,4,5,7-tetramethylisochromane-3,8-diol (), 3,4,5,7-tetramethylisochromane-3,6,8-triol (), streptimidone derivative (), along with ten known compounds (-) were isolated from the strain Sm4-1986. Their chemical structures were established based on the information from UV, IR, NMR (H NMR, C NMR, H-H COSY, HSQC, HMBC, NOESY), and mass spectroscopic. Moreover, all the isolated new compounds were evaluated for antibacterial activities (. , and methicillin-resistant ) and their cytotoxicities against MCF-7, A549, Hela tumor cell lines and Marc-145 normal cell line.
从菌株 Sm4-1986 中分离得到了三个新化合物,包括 6-甲氧基-3,4,5,7-四甲基异苯并二氢吡喃-3,8-二醇 ()、3,4,5,7-四甲基异苯并二氢吡喃-3,6,8-三醇 ()、链霉菌素衍生物 (),以及十个已知化合物 (-)。根据 UV、IR、NMR (H NMR、C NMR、H-H COSY、HSQC、HMBC、NOESY) 和质谱等信息确定了它们的化学结构。此外,还评估了所有分离得到的新化合物的抗菌活性(对 、 和耐甲氧西林金黄色葡萄球菌)以及对 MCF-7、A549、Hela 肿瘤细胞系和 Marc-145 正常细胞系的细胞毒性。
