[Neuroprotective effects of sulfated polysaccharides from seaweed].
Currently, neurodegenerative diseases (NDD) occupy a significant place in the structure of disease of the elderly, which dictates the need to find new and effective treatment and prevention of this pathology. At the heart of NDD development is a violation of the metabolism and the conformational change of cellular proteins with subsequent accumulation and aggregation of their in certain groups ...
متن کاملSulfated xylomannans from the red seaweed Sebdenia polydactyla: structural features, chemical modification and antiviral activity.
BACKGROUND Many viruses display affinity for cell surface heparan sulfate proteoglycans with biological relevance in virus entry. This raises the possibility of the application of sulfated polysaccharides in antiviral therapy. METHODS In this study, we analysed polysaccharide fractions isolated from Sebdenia polydactyla. RESULTS The purified xylomannan sulfate and its further sulfated deriv...
متن کاملChemical structure and antiviral activity of the sulfated heterorhamnan isolated from the green seaweed Gayralia oxysperma.
A homogeneous sulfated heterorhamnan was obtained by aqueous extraction, then by ultrafiltration from the green seaweed Gayralia oxysperma. Besides alpha-L-rhamnose it contains glucuronic and galacturonic acids, xylose and glucose. The structure was established by methylation analyses of the carboxyl-reduced, carboxyl-reduced/desulfated, carboxyl-reduced/Smith-degraded, and carboxyl-reduced/Smi...
متن کاملSulfated Seaweed Polysaccharides as Multifunctional Materials in Drug Delivery Applications.
In the last decades, the discovery of metabolites from marine resources showing biological activity has increased significantly. Among marine resources, seaweed is a valuable source of structurally diverse bioactive compounds. The cell walls of marine algae are rich in sulfated polysaccharides, including carrageenan in red algae, ulvan in green algae and fucoidan in brown algae. Sulfated polysa...
متن کاملAntiangiogenic activity and direct antitumor effect from a sulfated polysaccharide isolated from seaweed.
Angiogenesis is a dynamic proliferation and differentiation process. It requires endothelial proliferation, migration and tube formation. In this context, endothelial cells are a preferred target for several studies and therapies. Anionic polysaccharides (SV1 and PSV1) from brown seaweed Sargassum vulgare were fractionated (SV1), purified (PSV1) and displayed with high total sugars, sulfate con...
