Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti-Inflammatory and Anti-Ulcer Effects. [PDF]

Chem Biodivers
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Sulfated fucan as support for antibiotic immobilization [PDF]

Brazilian Journal of Medical and Biological Research, 2004
Xylofucoglucuronan from Spatoglossum schröederi algae was tested as a support for antibiotic immobilization. The polysaccharide (20 mg in 6 ml) was first activated using carbodiimide, 1-ethyl-3-(3-dimethylamino-propyl)carbodiimide methiodide (20 mg in 2 ml), under stirring for 1 h at 25 masculine C and pH from 4.5 to 5.0. After adjusting the pH to 8.0,

Antiviral activity of marine sulfated glycans against pathogenic human coronaviruses

Scientific Reports, 2023
Great interest exists towards the discovery and development of broad-spectrum antivirals. This occurs due to the frequent emergence of new viruses which can also eventually lead to pandemics.

SPR Sensor-Based Analysis of the Inhibition of Marine Sulfated Glycans on Interactions between Monkeypox Virus Proteins and Glycosaminoglycans

Marine Drugs, 2023
Sulfated glycans from marine organisms are excellent sources of naturally occurring glycosaminoglycan (GAG) mimetics that demonstrate therapeutic activities, such as antiviral/microbial infection, anticoagulant, anticancer, and anti-inflammation ...

Presence of Exogenous Sulfate Is Mandatory for Tip Growth in the Brown Alga Ectocarpus subulatus

Frontiers in Plant Science, 2020
Brown algae (Phaeophyceae) are multicellular photoautrophic organisms and the largest biomass producers in coastal regions. A variety of observations indicate that their extracellular matrix (ECM) is involved with screening of salts, development, cell ...

Monoclonal antibodies directed to fucoidan preparations from brown algae [PDF]

, 2015
Cell walls of the brown algae contain a diverse range of polysaccharides with useful bioactivities. The precise structures of the sulfated fucan/fucoidan group of polysaccharides and their roles in generating cell wall architectures and cell properties ...

The structure of a family 168 glycoside hydrolase from the marine bacterium Muricauda eckloniae. [PDF]

Acta Crystallogr F Struct Biol Commun
The structure of a putative fucoidan‐degrading glycoside hydrolase assigned to glycoside hydrolase family 168 reveals a (β/α)8 fold. The catalytic machinery and potential substrate specificity were investigated through a structural comparison with a Fun168A oligosaccharide complex.The genome of the marine bacterium Muricauda eckloniae sp.

Secretion of sulfated fucans by diatoms may contribute to marine aggregate formation [PDF]

Limnology and Oceanography, 2021
AbstractMicroalgae produce copious amounts of structurally diverse polysaccharides, some are bound within cells and cell walls, while others are secreted into the surrounding seawater. A fraction of the secreted polysaccharides assembles into particles promoting aggregation and in turn formation of aggregates increases the export of carbon into the ...

Structure, biology, evolution, and medical importance of sulfated fucans and galactans [PDF]

Glycobiology, 2008
Sulfated fucans and galactans are strongly anionic polysaccharides found in marine organisms. Their structures vary among species, but their major features are conserved among phyla. Sulfated fucans are found in marine brown algae and echinoderms, whereas sulfated galactans occur in red and green algae, marine angiosperms, tunicates (ascidians), and ...
