Sulfated 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 کاملBifunctional inhibitors of pepsin.
Two bifunctional reagents designed to probe the active site of pepsin and other acid proteinases are described. One of these, the bisdiazoketone 1,1-bis(diazoacetyl)-2-phenylethane inactivates pepsin at pH 5.0 much more rapidly than the corresponding monodiazoketon 1-diazoacetyl-2-phenylethane, whereas the other, the bromodiazoketone dl-1-diazoacetyl-1-bromo-2-phenylethane is less effective in ...
متن کاملSulfated polysaccharides fucoidans from brown algae
The immunotropic activity of structurally different fucoidans and their derivatives towards isolated immune blood cells, effectors of innate immune system, was studied. The most potent effect was observed for high molecular weight fucoidan CF from the alga Chordaria flagelliformis, whose backbone is built of (1→3)-linked units of α-L-fucopyranose, and branches included residues of α-D-glucuroni...
متن کاملEffects of sulfated polysaccharides on tumour biology.
Sulfated polysaccharides can act not only as anticoagulants but also as tumour inhibitors. Recent studies suggest that sulfated polysaccharides could affect tumour cells directly. Sulfated polysaccharides could inhibit the metastasis and proliferation of tumour cells by binding to growth factors and cell adhesion molecules. Moreover, sulfated polysaccharides could inhibit heparanase, which clea...
متن کامل[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 ...
