Marine animals novel natural products from

Screening of extracts obtained from terrestrial plants and animals has yielded a large number of novel natural products. Many of diese have been developed into useful medicinal agents either directly as the natural product or through synthetic modification. It has been estimated that for the period 1983-1994, 78% of the antibacterial agents and 61% of the 31 anticancer agents approved for use, were derived from terrestrial natural products. By comparison the marine environment remains relatively unexplored.
