Book excerpt: The first of its kind, this dictionary defines more than 25,000 marine- natural products. It indexes each by chemical name, organism type, and compound type. Following a similar format to the Chapman & Hall Chemical Database, each entry includes biological source, chemical structure, physical properties, biological activity, and literature references. With an accompanying CD, this invaluable tool offers immediate access to information essential to the development of novel pharmaceuticals, pesticides, and marine anti-fouling agents derived from unique molecular structures of marine natural products.
