Natural products as antifouling compounds: recent progress and future perspectives

Area of Science:

• Marine biology
• Environmental science
• Materials science

Background:

• International treaties since 2008 have banned organotin compounds (e.g., tributyltin (TBT)) in antifouling (AF) coatings.
• Existing AF coatings using Cu2O and other biocides pose environmental risks.
• There is an urgent need for effective, non-toxic, and environmentally friendly green AF agents.

Purpose of the Study:

• To review important AF compounds discovered from natural organisms between 2004 and mid-2009.
• To discuss current trends in the discovery of novel AF compounds.
• To provide a perspective on the future development of AF compounds.

Main Methods:

• Literature review of scientific publications from 2004 to mid-2009.
• Analysis of identified natural AF compounds and their sources.
• Discussion of general trends and challenges in AF research.

Main Results:

• Several AF compounds from diverse marine organisms have been identified.
• Trends indicate a shift towards naturally derived, low-toxicity AF agents.
• The review synthesizes findings on efficacy and environmental impact.

Conclusions:

• The development of green AF compounds is crucial for sustainable marine industries.
• Continued research into natural products is essential for discovering next-generation AF solutions.
• Addressing environmental concerns requires innovative and eco-friendly AF technologies.
