A new series of lipids called mololipids have been identified from an Hawaiian sponge of the order Verongida. The structures of these lipids was deduced from spectroscopic data of the lipid mixture combined with GC-MS analysis. The core of this novel series of lipids is a bromotyramine homoserinederived moiety known as moloka’iamine (1) which is found in many Verongid sponge metabolites. Moloka’iamine forms bisamides with a diverse series of fatty acids and the mololipids mixture (2) was active against HIV-1 with an EC50 of 52.2μM without cytotoxicity in human lymphocytes (IC50 > 100μ M). |

从一种order Verongida夏威夷海绵中鉴定了一系列新的叫mololipid 的脂类。通过脂类混合物的光谱数据再结合气质分析推导出了这些脂类的结构。 这个新系列脂的核心是从已知的Moloka’iamine衍生出的一个溴酪胺高丝氨酸 (1),在很多Verongid海绵代谢物中都发现这种高丝氨酸(或者是moloka胺,要看文章的context来定到底哪个指代词) . Moloka’iamine 和多种系列的脂肪酸形成了双酰胺,molol脂混合物 (2)有抗HIV-1活性,其 EC50 为 52.2μM,在人淋巴细胞内没有细胞毒性(IC50 >100μ M). ![]() ![]() |
