Sulfated Seaweed Polysaccharides
2021Mankind has used natural resources for many different applications, from food and clothes to drugs, but only recently is giving the due attention to the need for a responsible management of these resources toward sustainability. One of the approaches is to take the most out of its resources, addressing the several components of natural resources, which

Sulfation of Polysaccharides using Monomethyl Sulfate
Journal of Carbohydrate Chemistry, 2000ABSTRACT The polysaccharides, curdlan, starch and dextran were sulfated when heated in DMSO with sodium methyl sulfate and a catalytic amount of H2SO4 or with pyridinium methyl sulfate. Use of diminished pressure and anhydrous CaSO4 as a desiccant improved the degree of sulfation and recovery.

Secretion of Sulfated Polysaccharides by the Gastric Mucosa
Digestion, 2009Presence of chondroitin-4-sulfate has been demonstrated in the gastric fundic juice of the dog. It is secreted by the chief peptic cells. Chondroitin sulfate-like material was also observed in the pyloric cells of the same animal. In the dog, chondroitin-4- sulfate secretion by the fundus is increased during cholinergic stimulation but not during ...

A Sulfated Polysaccharide Produced by an Arthrobacter Species
The Journal of Biochemistry, 1982A new sulfated polysaccharide was isolated from the culture supernatant of a strain of Arthrobacter sp. The polysaccharide purified with quaternary ammonium salts consists of D-galactose, D-glucose, sulfate, phosphorus, glucosamine, muramic acid, alanine, glutamic acid, glycine, and LL-diaminopimelic acid in a molar ratio of 56 : 9.0 : 68 : 6.4 : 2.0 :

Sulfated polysaccharides and their anticoagulant activity: A review
Applied Biochemistry and Microbiology, 2010Published data on the sulfated polysaccharides of various origins that display an anticoagulant activity are summarized and analyzed. The methods used for producing semisynthetic derivatives are considered. A key role of the polysaccharide structure in the mechanisms of specific interaction with various blood plasma proteinases is discussed.

Anticoagulant properties of semisynthetic polysaccharide sulfates
Thrombosis Research, 1991Several naturally occurring polysaccharides were purified and subsequently sulfated by chlorosulfonic acid-pyridine complex. These were isolated as the sodium salt and further purified by ECTEOLA cellulose chromatography. Anticoagulant properties of the sulfated polysaccharides were compared with commercial heparin by measuring their in vitro effects ...

Modification of lymphocyte migration by sulfated polysaccharides
European Journal of Immunology, 1986AbstractThe role of sulfated polysaccharides in lymphocyte migration has been analyzed in vivo using lymphocytes labeled with an intracellular DNA‐binding fluorochrome Hoechst 33342. The influence of a panel of sulfated polysaccharides on entry (by injecting the sulfated polysaccharide prior to the labeled cells) and displacement from lymphoid organs ...

Anti-inflammatory action of sulfated polysaccharides
Biochemical Pharmacology, 1969Abstract A number of sulfated polymers: pentosan polysulfate, polyvinyl sulfate, polyethylene sulfonate, cellulose sulfate, dextran sulfate, sulfate amylopectin, in the same way as carragenin, degraded carragenin and dextran, produce edema in the rat's paw by local injection, to release kinins from fresh guinea pig and rat's plasma (in vitro) and to ...

Sulfated Seaweed Polysaccharides as Antiviral Agents
Current Medicinal Chemistry, 2004Several sulfated seaweed polysaccharides show high antiviral activity against enveloped viruses, including important human pathogens such as human immunodeficiency virus, herpes simplex virus, human cytomegalovirus, dengue virus and respiratory syncytial virus. They can be obtained in major amounts and at low costs, have low toxicity and in some cases,

Determination of the positions of the sulfate groups in sulfated polysaccharides
Chemistry of Natural Compounds, 19761. The possibility has been shown of using a method proposed by us previously to determine the positions of the sulfate groups in sulfated polysaccharides. 2. The positions of the sulfate groups in the following sulfated polysaccharides have been determined: fucan and pelvecyan fromPelvetia wrightii and sargassan fromSargassum pallidum.
