Based on the One Strain-Many Compounds (OSMAC) strategy, the secondary metabolites of FS508 were investigated. As a result, a new secondary metabolite, 4-methoxy-3-[4-(acetyloxy)-3-methyl-2-butenyl]benzoic acid () as well as eleven known compounds were isolated from the fermentation product of the strain FS508. Their structures were determined by NMR, IR, UV, and MS spectroscopic data analyses. All the isolated compounds were evaluated for cytotoxic and anti-inflammatory activities. Among them, compounds and displayed potent cytotoxicity against HepG-2 cell line, and compounds , and showed significant anti-inflammatory activities.
基于“一菌多物”（OSMAC）策略，对 FS508 的次级代谢产物进行了研究。结果，从 FS508 菌株的发酵产物中分离得到了一种新的次级代谢产物 4-甲氧基-3-[4-(乙酰氧基)-3-甲基-2-丁烯基]苯甲酸（）以及十一种已知化合物。通过 NMR、IR、UV 和 MS 光谱数据分析确定了它们的结构。所有分离得到的化合物均进行了细胞毒性和抗炎活性评价。其中，化合物和对 HepG-2 细胞系表现出较强的细胞毒性，化合物、和具有显著的抗炎活性。
