A new preussomerin isomer, 3'-O-demethylpreussomerin I, five known preussomerins E - I, and two known deoxypreussomerins, deoxypreussomerin A and bipendensin (palmarumycin C11), were isolated from a lichenicolous fungus Microsphaeropsis sp. BCC 3050. These structures were elucidated by spectroscopic methods, especially 1D- and 2D-NMR. The preussomerins were evaluated for their antimycobacterial and antiplasmodial activities as well as cytotoxicity against KB, BC-1 and vero cell lines.
从一种地衣内生真菌微小球壳菌属Microsphaeropsis sp. BCC 3050中分离出一种新的前乌斯莫菌素异构体3'-O-去甲基前乌斯莫菌素I、五种已知的前乌斯莫菌素E - I以及两种已知的脱氧前乌斯莫菌素,脱氧前乌斯莫菌素A和双悬菌素(棕榈霉素C11)。这些结构通过光谱方法,尤其是一维和二维核磁共振进行了阐明。对前乌斯莫菌素的抗分枝杆菌和抗疟原虫活性以及对KB、BC-1和vero细胞系的细胞毒性进行了评估。
