The marine environment provides a rich source of natural products with potential therapeutic application.This has resulted in an increased rate of pharmaceutical agents being discovered in marine animals,particularly invertebrates.Our objective is to summarize the most promising compounds which have the best potential and may lead to use in clinical practice,show their biological activities and highlight the compounds currently being tested in clinical trials.In this paper,we focused on Bryozoa,Mollusca,Echinodermata and Urochordata.
