Cyanobacterial metabolites have proven to be invaluable as tools in thedissection of signal transduction pathways in mammalian cells and some arecurrently under clinical evaluation as drug candidates. It is now also realizedthat cyanobacteria are the true biosynthetic origin of many bioactive moleculesisolated from marine invertebrates; marine invertebrates may sequestercyanobacteria through diet or by symbiosis. This review discusses thedietary-derived cyanobacterial origin of the dolastatins, potent cytotoxiccompounds, originally isolated from the Indian Ocean sea hare,Dolabella auricularia. A discussion on the dietarydissemination of cyanobacterial metabolites through the marine food chain isalso presented. Reference to the metabolites isolated fromDysidea sponges is given to illustrate their origin fromsymbiotic cyanobacteria associated with this organism.
