Researchers are exploring brown algae as a source of potential treatments for Oral Squamous Cell Carcinoma (OSCC), a prevalent and aggressive form of oral cancer. Brown algae are rich in bioactive compounds, including polyphenols, carotenoids, fatty acids, and polysaccharides, which show promise in inhibiting cancer cell growth and inducing apoptosis. These compounds work through various mechanisms such as cell cycle arrest, apoptotic cell death, and inhibition of angiogenesis. Fucoxanthin and fucoidan, found in brown algae, have shown significant anti-OSCC properties by targeting specific pathways involved in cancer progression. Additionally, celecoxibloaded chitosan-fucoidan nanoparticles demonstrate potential in multiple pathways for OSCC treatment. Challenges in translating these findings into clinical applications include the need for further preclinical studies, efficient extraction methods, and clinical trials for safety and efficacy assessment. Despite challenges, brown algal compounds offer a promising avenue for developing novel and effective OSCC therapies, drawing from the ancient wisdom of the sea.
