Seaweed-derived compounds show promise in pharmaceuticals, cosmeceuticals, and sustainable biomaterials.
Abstract
The Portuguese Atlantic coast harbors a remarkably diverse macroalgal flora, shaped by the intersection of Lusitanian, Mediterranean, and boreal biogeographic influences. This diversity is reflected in the rich repertoire of secondary metabolites produced by local seaweeds, including halogenated compounds, terpenoids, phlorotannins, mycosporine like amino acids, sulfated polysaccharides, and unique phenolic structures. These metabolites exhibit a wide range of bioactivities, antioxidant, anti-inflammatory, antimicrobial, antiviral, antifouling, antitumoral, and neuroprotective, positioning Portuguese seaweeds as promising sources of novel bioactive agents. This review synthesizes the current state of knowledge on the chemical diversity and biological properties of metabolites isolated from seaweeds along the Portuguese Atlantic coast. We examine species-specific metabolite profiles,…
