Bioassay-guided isolation of antiviral compounds from the cultured cyanobacterium Microcystis ichthyoblabe provided two novel cyclic depsipeptides, ichthyopeptins A (1) and B (2). Their structures were determined by 1D (1H and 13C) and 2D (COSY, TOCSY, ROESY, HMQC, and HMBC) NMR spectra, ESIMS-MS, and amino acid analysis. The fraction containing both cyclic depsipeptides exhibited antiviral activity against influenza
从培养的蓝藻微囊藻鱼腥藻中生物测定指导的抗病毒化合物分离提供了两种新的环状双缩肽,鱼鳞肽A(1)和B(2)。它们的结构由1D(1H和13C)和2D(COSY,TOCSY,ROESY,HMQC和HMBC)NMR光谱,ESIMS-MS和氨基酸分析确定。包含两种环二倍肽的组分均表现出针对A型流感病毒的抗病毒活性,IC50值为12.5 microg / mL。
