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). |

從一種order Verongida夏威夷海綿中鑒定了一系列新的叫mololipid 的脂類。通過(guò)脂類混合物的光譜數(shù)據(jù)再結(jié)合氣質(zhì)分析推導(dǎo)出了這些脂類的結(jié)構(gòu)。 這個(gè)新系列脂的核心是從已知的Moloka’iamine衍生出的一個(gè)溴酪胺高絲氨酸 (1),在很多Verongid海綿代謝物中都發(fā)現(xiàn)這種高絲氨酸(或者是moloka胺,要看文章的context來(lái)定到底哪個(gè)指代詞) . Moloka’iamine 和多種系列的脂肪酸形成了雙酰胺,molol脂混合物 (2)有抗HIV-1活性,其 EC50 為 52.2μM,在人淋巴細(xì)胞內(nèi)沒(méi)有細(xì)胞毒性(IC50 >100μ M). ![]() ![]() |
