Natural Products as Potential Antiviral Drugs: The Specific Case of Marine Biotoxins.

To fight against various viral infections researchers turned to new chemical structures resulting from natural medicinal plants and more recently from "marine origin" as sources of active molecules against viral infections. The present manuscript describes complex marine origin drugs, their chemical complex structure, their therapeutic use, and their antiviral properties. Emphasis is placed more particularly on the properties of ionic channels (Na, K, Ca) blockers compounds from marine origin, named , derived from "dinoflagellates microalgae".
