As part of our search for new cytotoxic and antimicrobial natural products from endolichenic fungi, 19 compounds including 1 new 10-member lactone (2: ), 1 new polyacetylene glycoside (3: ), 1 new brasilane-type sesquiterpenoid glycoside (4: ), and 2 isobenzofuran-1(3H)-one derivatives (5: and 6: ) were isolated from the solid culture of the endolichenic fungus Hypoxylon fuscum. Their structures were
我们从内分泌真菌中寻找新的细胞毒性和抗菌天然产物的一部分,其中包括19种化合物,包括1种新的10元内酯(2:),1种新的聚乙炔糖苷(3:),1种新的Brasil型倍半萜糖苷(4:)。 ,和2异苯并呋喃-1(3H)-一衍生物(5:和6:)从内胚层真菌Hypoxylon fuscum的固体培养物中分离得到。NMR光谱数据,MS,ECD(电子圆二色性)计算和化学方法清楚地阐明了它们的结构。评估了对K562,SW480和HEPG2细胞系的细胞毒性作用以及对枯草芽孢杆菌,金黄色葡萄球菌,大肠杆菌和白色念珠菌的抗菌活性。化合物1:2和5:对K562,SW480和HEPG2细胞系具有中等的细胞毒性,而化合物1、9和11:
