Several groups of structurally-related compounds, comprised of either five or six-membered ring structures with attached lipophilic carbon chains and in some cases possessing halogen atoms, have been isolated from various marine algae and filamentous cyanobacteria. The related compounds considered in the present work include the coibacins, laurenciones,(More)
