Typification of chemical compounds of marine sponge metabolites

Abstract

Sponges are the storehouse of extraneous marine biota paving way for the formation of unique structured organic compounds with interesting biological activities either by themselves or by their symbionts in the form of secondary metabolites for their defense from their enemies. Some compounds are specific to the genus and some are dependent on the location. The range of compounds includes major classes viz., terpenoids, alkaloids, heterocycles, steroids, polyacetylenes, peptides, polyethers, polyketides, macrolides, glycosides, and nucleosides. Major compounds under each class with reported biological activities are discussed. Compounds with unique structural features and chemical interest are taken into account.
