A fucan specific lectin on teratocarcinoma stem cells
Biochemical and Biophysical Research Communications, 1981Summary Teratocarcinoma stem cells have a cell surface carbohydrate-binding component detected by rosetting of intact stem cells with erythrocytes. We now report a soluble hemagglutination activity in stem cell extracts with a carbohydrate- and erythrocyte-binding specificity almost identical to that of the cell surface rosette-mediating factor.

Reversible disruption of cultured endothelial monolayers by sulphated fucans
Journal of Cell Science, 1983ABSTRACT We have examined the effects of a variety of polysaccharides and glycoconjugates on the organization and morphology of cultured AI4CL-I endothelial monolayers. The sulphated fucose-containing polysaccharides, fucoidin and sea-urchin egg jelly fucan, induce a dramatic disruption of the organization of the monolayers ...

Relationship between Sulfate Groups and Biological Activities of Fucans
Thrombosis Research, 2000The anticoagulant and antiproliferative effects of low molecular weight fucans with different sulfate content were examined. The anticoagulant activity was determined by activated partial thromboplastin time and the antiproliferative one was achieved in vitro on CCL39 fibroblast cell line.

A highly regular fucan sulfate from the sea cucumber Stichopus horrens
Carbohydrate Research, 2018A highly regular fucan sulfate SHFS was isolated from the sea cucumber Stichopus horrens by extraction of the body walls in the presence of papain followed by ion-exchange and gel permeation chromatography. SHFS had MW of about 140 kDa and contained fucose and sulfate in the molar ratio of about 1:1.

Antiproliferative effect and interaction of fucans with cells
Colloids and Surfaces B: Biointerfaces, 1994Abstract Fucans were extracted from the brown seaweed Ascophyllum nodosum , degraded by acidic hydrolysis, fractionated by gel nitration and characterized by high performance steric exclusion chromatography. Different fucan fractions of average molecular weight 6000–150000 g mol −1 were thus obtained. The effects of these low molecular weight (LMW)

Searching for Alternatives to Heparin Sulfated Fucans from Marine Invertebrates
Trends in Cardiovascular Medicine, 1999We describe a variety of sulfated polysaccharides with regular and well-defined structures which are useful tools for elucidating structure/biological function relationship. Several of these compounds have anticoagulant and antithrombotic activities.

Fractionation and analysis of fucans from brown algae
Phytochemistry, 1990Abstract Cell walls were isolated from the brown algae Pelvetia canaliculata, Fucus vesiculosus, Sargassum muticum (Fucales) and Laminaria digitata (Laminariales) and then submitted to sequential chemical extraction. Various fucans were isolated, i.e.

Water soluble sulfated-fucans with immune-enhancing properties from Ecklonia cava
International Journal of Biological Macromolecules, 2014Water-soluble sulfated fucans isolated from Ecklonia cava were fractionated using an anion-exchange chromatography to investigate their molecular characteristics and immunomodulating activities. The crude fucoidan extract and purified fractions (EF1, EF2, and EF3) consisted mostly of different ratios of neutral sugars, proteins, sulfates, uronic acids,

Molecular characterization and immunomodulatory activity of sulfated fucans from Agarum cribrosum
Carbohydrate Polymers, 2014The sulfated-fucans, known as fucoidans, were isolated from Agarum cribrosum and fractionated using ion-exchange chromatography to determine their molecular characteristics and in vitro immunomodulatory activity. The crude and fractionated fucoidans (F1 and F2) consisted mostly of carbohydrates (52.4-56.0%), sulfates (12.7-23.0%) and uronic acid (14.1 ...

Synthesis and Characterization of Fucan-Coated Cobalt Ferrite Nanoparticles
Journal of Superconductivity and Novel Magnetism, 2012This work presents some results of the synthesis and structural, microstructural, and magnetic characterization of fucan coated cobalt ferrite nanoparticles prepared by using a modified coprecipitation method. Aqueous suspensions of magnetic particles were prepared by coprecipitation of Fe(III) and Co(II) in the presence of NaOH, acid oleic and fucan ...
