Pharmacological Properties and Phytochemical Profile of Sargassum filipendula Extracts

초록

Sargassum filipendula is a widely distributed, edible brown alga that possesses a rich nutritional profile. Several studies have demonstrated that the components/extracts of S. filipendula (SFE) possess diverse pharmacological potential against both infectious and non-infectious diseases. These include antibacterial and antifungal properties, as well as antioxidant, anti-aging, anti-osteoporosis, antiviral, antiprotozoal, and immunomodulatory effects. Furthermore, SFE has shown significant anticancer activity across various malignant cell lines. The unique phytochemical profile of this species, characterized by the presence of sulfated polysaccharides (primarily fucoidan), carotenoids, phenols, glycolipids, and phlorotannins, serves as the foundation for these wide-ranging pharmacological activities. Studies have demonstrated that SFE can modulate key molecular targets, such as glycogen synthase kinase-3 beta, and activate the mitochondrial-dependent apoptosis pathway, providing a robust mechanistic basis for the observed pharmacological activities. Recent evaluations of nutritional parameters and techno-functional properties confirm the rich nutritional profile of S. filipendula, supporting its application in a diverse range of food products. Despite its diverse bioactive phytochemicals and broad efficacy against infectious and non-infectious diseases, research on S. filipendula remains largely restricted to in vitro preclinical studies. The lack of a comprehensive compilation of its pharmacological activities, phytochemical profiles, and molecular targets hinders its development as a therapeutic agent. This review aims to bridge this gap by compiling the existing knowledge, identifying research deficiencies, particularly the lack of in vivo data and safety assessments for high-dose therapeutic applications, while proposing suggestions for transitioning S. filipendula into a viable therapeutic or functional supplement.
