Glycolipids from Sponges. Part 17. Clathrosides and Isoclathrosides, Unique Glycolipids from the Caribbean Sponge <i>Agelas </i><i>c</i><i>lathrodes</i>
unique glycolipids, clathrosides A-C (2a-4a) and isoclathrosides A-C (5a-7a) were isolated from the Caribbean sponge Agelas clathrodes. Clathrosides and isoclathrosides are glycosides of a very-long-chain alcohol derived from fatty acids, a newclass of glycolipids that appears to be characteristic of marinesponges. The six compounds differ in configuration and in the branching of alkyl chains. Stereostructures
