An Overview of Synthesis of Indole Alkaloids and Biological Activities of Secondary metabolites Isolated from Hyrtios Species.

This review article is focused on the importance of marine sponges in pharmaceutical field by explaining the possible biological activities exhibited by the secondary metabolites, which were extracted from, one of the important class of marines sponges, Hyrtios sp. Marine sponges are the source for more than 50% of marine natural compounds have been isolated from marine organisms. Also, the review dealt with some of the reported synthetic routes to the indole alkaloids which are extracted from the marine sponge Hyrtios sp.
