Ouhanamide (), a new linear lipopeptide consisting of a long-chain fatty acid with a β-branched methyl group, was isolated from a marine sp. cyanobacterium. The overall structure was elucidated by a combination of various spectroscopic analyses, degradation reactions, and derivatizations. Ouhanamide () showed selective antiparasitic activity (IC = 1.2 ± 0.1 μM against and IC = 4.2 ± 0.9 μM against ) without cytotoxicity at 10 μM against HeLa cells.
欧哈酰胺（）是一种新的线性脂肽，由带有β-分支甲基的长链脂肪酸组成，从一种海洋蓝藻中分离得到。通过各种光谱分析、降解反应和衍生化反应相结合的方法阐明了其整体结构。欧哈酰胺（）表现出选择性抗寄生虫活性（对的IC = 1.2 ± 0.1 μM，对的IC = 4.2 ± 0.9 μM），在10 μM浓度下对HeLa细胞无细胞毒性。
