Here, we report wajeepeptin (), a new cyclic depsipeptide isolated from a marine sp. cyanobacterium. The structure was elucidated by a combination of spectroscopic analyses, X-ray diffraction analysis, and degradation reactions. Wajeepeptin () showed moderate cytotoxicity (IC = 3.7 μM against HeLa cells) and potent antitrypanosomal activity (IC = 0.73 ± 0.14 μM against ).
在这里，我们报告了一种从海洋 蓝藻中分离得到的新型环二肽wajeepeptin()。通过光谱分析、X 射线衍射分析和降解反应的组合，确定了其结构。Wajeepeptin()表现出中等的细胞毒性（对 HeLa 细胞的 IC = 3.7 μM）和强大的抗锥虫活性（对 的 IC = 0.73 ± 0.14 μM）。
