Neritaloside is primarily investigated for its potential bioactive properties, particularly in marine-derived natural product research. It has shown preliminary antifouling activity, meaning it may help prevent the attachment of microorganisms, algae, and small invertebrates to submerged surfaces such as ship hulls or aquaculture equipment. This application is valuable in reducing the need for toxic antifouling coatings and minimizing ecological impact. Additionally, due to its structural complexity and origin from marine organisms, it serves as a lead compound in the development of new pharmaceuticals, with ongoing studies exploring possible antimicrobial or cytotoxic effects. Its role in chemical defense mechanisms in marine life also makes it a subject of interest in ecological and chemical signaling studies.
