Antifouling Compounds from Marine Invertebrates.

Area of Science:

• Marine Biology
• Natural Products Chemistry
• Biotechnology

Background:

• Biofouling poses significant challenges in marine environments, impacting industries like shipping and aquaculture.
• Natural products from marine organisms offer a sustainable source of novel antifouling solutions.
• Marine invertebrates, including sponges and corals, are known for producing bioactive secondary metabolites.

Purpose of the Study:

• To provide a comprehensive review of antifouling compounds isolated from marine invertebrates.
• To catalog the diversity and chemical structures of identified antifouling agents.
• To highlight the potential of marine invertebrates as a source for developing eco-friendly antifouling strategies.

Main Methods:

• Literature review of scientific databases (e.g., PubMed, Scopus, Web of Science).
• Systematic search for studies reporting isolation and characterization of antifouling compounds from marine invertebrates.
• Data extraction and synthesis of information on compound sources, chemical classes, and reported antifouling activity.

Main Results:

• Over 198 distinct antifouling compounds have been identified from marine invertebrates.
• Key invertebrate phyla investigated include Porifera (sponges) and Cnidaria (gorgonian and soft corals).
• Compounds span various chemical classes, including terpenoids, alkaloids, and macrolides, exhibiting diverse antifouling mechanisms.

Conclusions:

• Marine invertebrates are a rich reservoir of structurally diverse antifouling compounds.
• Further research into these natural products could lead to the development of effective and environmentally benign antifouling technologies.
• Continued exploration of marine invertebrate chemical defenses is crucial for discovering novel bioactive molecules.
