Antioxidant activities of sulfated pumpkin polysaccharides

International Journal of Biological Macromolecules, 2019
Pumpkin polysaccharide was extracted by hot water extraction method. It was modified with chlorosulfonic acid-pyridine to obtain sulfated pumpkin polysaccharides (SP1, SP2) with different degrees of substitution, which was 0.35 and 0.65, respectively.

A Sulfated Polysaccharide Produced by an Arthrobacter Species

The Journal of Biochemistry, 1982
A 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, 2010
Published 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, 1991
Several 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, 1986
AbstractThe 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, 1969
Abstract 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, 2004
Several 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, 1976
1. 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.

Astragalus polysaccharide and sulfated epimedium polysaccharide synergistically resist the immunosuppression

Carbohydrate Polymers, 2012
The immunoenhancement of compound polysaccharides, APS-sEPS composed with astragalus polysaccharide (APS) and sulfated epimedium polysaccharide (sEPS), was observed in immunosuppressed model chicken induced by cyclophosphamide (Cy). 11-day-old chickens were injected with Cy once a day for three successive days except vaccine control group.

Complexation of β-Lactoglobulin Fibrils and Sulfated Polysaccharides

Biomacromolecules, 2011
Fibrils of β-lactoglobulin, formed by heating at pH 2, were titrated with a sulfated polysaccharide (κ-carrageenan) to determine the morphology and mechanism of complex formation at low pH. Structural information on the resultant complexes was gathered using transmission electron microscopy, atomic force microscopy, Doppler electrophoresis, and small ...
