A novel cyclic tripeptide, sclerotiotide M (), was isolated from the culture of a marine derived fungus DSW-2, together with four known compounds (-). The planar structure of was established by 1 D and 2 D NMR data, supported by mass spectrometry, and the relative configuration was established by calculated NMR chemical shifts coupled with a statistical method (DP4+). All the compounds (-) displayed weak cytotoxic activities against cancer cell lines HPAC and BXPC3, with IC values over 20 μM.
一种新型环三肽 sclerotiotide M () 从海洋来源真菌 DSW-2 的培养物中分离得到，同时还分离得到了四个已知化合物 (-)。化合物 的平面结构通过 1D 和 2D NMR 数据、质谱以及计算 NMR 化学位移与统计方法 (DP4+) 确定的相对构型来建立。所有化合物 (-) 对 HPAC 和 BXPC3 癌细胞系表现出较弱的细胞毒性，IC 值均超过 20 μM。
