Abstract

The Ocean, which is called the ?mother of origin of life?, is also the source of structurally unique natural products that are mainly accumulated in living organisms. Modern technologies have opened vast areas of research for the extraction of biomedical compounds from oceans and seas. Several of these compounds show pharmacological activities and are helpful for the invention and discovery of bioactive compounds, primarily for deadly diseases like cancer, acquired immuno-deficiency syndrome (AIDS), arthritis, etc., while other compounds have been developed as analgesics or to treat inflammation, etc. The lifesaving drugs are mainly found abundantly in sponges (37%), coelenterates (21%) and microorganisms (18%) followed by algae (9%), echinoderms (6%), tunicates (6%), molluscs (2%) bryozoans (1%), etc. The famous proverb ?Poison kills the Poison? is the basis for the researchers in finding the biomedical metabolites from the living organisms.
