A new β-resorcylic macrolide, 5′-hydroxyzearalenone (1), and six known β-resorcylic macrolides were isolated from the seagrass-derived fungus Fusarium sp. PSU-ES73. Their structures were established by analysis of spectral data. All of the isolated compounds were evaluated for their antibacterial activity against Staphylococcus aureus, both standard and methicillin-resistant strains, as well as their antifungal activity against Cryptococcus neoformans. Only the known compound zearalenone (2) displayed weak antibacterial and antifungal activities.
从海草源真菌 Fusarium sp. PSU-ES73 中分离出了一种新的β-残基大环内酯--5′-羟基玉米赤霉烯酮(1)和六种已知的β-残基大环内酯。通过分析光谱数据,确定了它们的结构。评估了所有分离化合物对金黄色葡萄球菌(包括标准菌株和耐甲氧西林菌株)的抗菌活性,以及对新型隐球菌的抗真菌活性。只有已知化合物玉米赤霉烯酮(2)显示出微弱的抗菌和抗真菌活性。
