A new class of diterpene-pentosides, the seco-pseudopterosins (1–4), has been isolated from a Caribbean sea whip of the genus Pseudopterogorgia. The new compounds are arabinose glycosides possessing aglycones of the serrulatane class, the compounds in the series are mono-acetate positional isomers, and they are related to the recently described pseudopterosins by bond cleavage at the C5 – C13 positions
一类新的二萜-戊糖苷,seco-pseudopterosins (1-4),是从Pseudopterogorgia属的加勒比海鞭中分离得到的。新化合物是具有Serrulatane类糖苷配基的阿拉伯糖苷,该系列化合物是单乙酸酯位置异构体,它们通过C5-C13位置的键断裂与最近描述的拟蝶呤相关。脂多糖-维骨脂蛋白具有与市售抗炎药相当的有效抗炎和止痛活性。这些新化合物的结构是在综合光谱分析和化学转化的基础上提出的。
