Three new fusarielins, 3-epi-fusarielin H (1), 3-O-methyl-fusarielin H (2), and 3-O-methyl-epi-fusarielin H (3), were isolated from the fungus Fusarium sp. together with the known analogues, fusarielins F (4) and G (5). The structures of these compounds were elucidated by analysis of their ESI-HRTOFMS, 1D and 2D NMR spectroscopic data. The new compounds exhibited weak antibacterial effect against Staphylococcus aureus.
从镰刀菌属真菌中分离出三种新的镰孢菌素,即3-表镰孢菌素H(1)、3-O-甲基镰孢菌素H(2)和3-O-甲基-表镰孢菌素H(3),以及已知类似物镰孢菌素F(4)和G(5)。通过对它们的电喷雾高分辨飞行时间质谱(ESI-HRTOFMS)、一维和二维核磁共振光谱数据的分析,阐明了这些化合物的结构。这些新化合物对金黄色葡萄球菌表现出微弱的抗菌作用。
