冲绳海洋蓝藻 Okeania sp 的生物测定引导分离。导致分离出 26 元环缩肽 odoamide (1)。 1 的总体结构通过 1D 和 2D NMR 分析确定,而其绝对立体化学则使用各种不同的方法确定,包括合成和化学降解,然后进行手性 HPLC 分析。值得注意的是,odoamide (1) 对 HeLa S3 人宫颈癌细胞表现出有效的细胞毒性,IC50 值为 263 nM。 (C) 2016 Elsevier Ltd. 保留所有权利。
The bioassay-guided fractionation of the Okinawan marine cyanobacterium Okeania sp. led to the isolation of the 26-membered cyclodepsipeptide odoamide (1). The gross structure of 1 was determined by 1D and 2D NMR analyses, whereas its absolute stereochemistry was determined using a variety of different methods, including synthesis and chemical degradation followed by chiral HPLC analysis. Notably, odoamide (1) showed potent cytotoxicity against HeLa S3 human cervical cancer cells with an IC50 value of 263 nM. (C) 2016 Elsevier Ltd. All rights reserved.
