  • Title: Isolation and structure determination of the biologically active sphingolipids from marine sponge Haliclona species.
    Author: Ayyad SE, Bahaffi SO, Hashish NE.
    Journal: Nat Prod Res; 2009; 23(1):44-50. PubMed ID: 18989826.
    Abstract:
    In a continuation to our study on the marine sponge Haliclona species we have isolated three new cytotoxic components of sphingolipids (1-3). Methanolysis of the sphingolipid 1a-d in methanol produces fatty acid methyl ester. GC/MS was used to determine the length. The structure of each isolated compound has been determined on the basis of spectroscopic data and chemical evidence.
