Five new (⁻) and two known xanthones ( and ), one of the latter () obtained for the first time as a natural product, together with three known anthraquinones, questin, penipurdin A, and questinol, were isolated from the coastal saline soil-derived by application of an OSMAC (one strain many compounds) approach. Their structures were determined by interpretation of nuclear magnetic resonance (NMR) and high-resolution electrospray ionization mass spectroscopy (HRESIMS) data, as well as comparison of these data with those of related known compounds. Antiviral activity of xanthones - was evaluated through the cytopathic effect (CPE) inhibition assay, and compound exhibited distinctly strong activity towards influenza virus (H1N1), herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) with IC values of 44.6, 21.4, and 76.7 μM, respectively, which indicated that it was worth to further investigate it as a potential lead compound. The preliminary structure-activity relationship of the xanthones is discussed.
从沿海盐土来源的 中，通过应用 OSMAC（一种菌株多种化合物）方法分离得到了五个新的（⁻）和两个已知的黄烷酮（和），其中一个是首次作为天然产物获得的，以及三种已知的蒽醌，questin、penipurdin A 和 questinol。通过核磁共振（NMR）和高分辨率电喷雾电离质谱（HRESIMS）数据的解释以及与相关已知化合物的数据比较，确定了它们的结构。通过细胞病变效应（CPE）抑制试验评估了黄烷酮 - 的抗病毒活性，化合物 对流感病毒（H1N1）、单纯疱疹病毒 1 型（HSV-1）和 2 型（HSV-2）表现出明显的强活性，IC 值分别为 44.6、21.4 和 76.7 μM，这表明它值得进一步研究作为一种有潜力的先导化合物。讨论了黄烷酮的初步结构-活性关系。
