Heterofucan from Sargassum filipendula Induces Apoptosis in HeLa Cells
Marine Drugs, 2011 Fucan is a term used to denominate a family of sulfated polysaccharides rich in sulfated L-fucose. Heterofucan SF-1.5v was extracted from the brown seaweed Sargassum filipendula by proteolytic digestion followed by sequential acetone precipitation.

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 ...

Sulfated fucans extracted from algae Padina gymnospora have anti-inflammatory effect [PDF]
Revista Brasileira de Farmacognosia, 2012 Sulfated polysaccharides were extracted with acetone from brown algae Padina gymnospora. The fraction precipitated with 1.5 volumes of acetone (F1.5) purified in Sephadex G-75 was characterized by infrared and nuclear magnetic resonance of 13C and 1H, through which the presence of sulfate groups on the C4 of α-L-fucose could be observed.

Heterofucans from Dictyota menstrualis have anticoagulant activity
Brazilian Journal of Medical and Biological Research, 2004 Fucan is a term used to denote a family of sulfated L-fucose-rich polysaccharides which are present in the extracellular matrix of brown seaweed and in the egg jelly coat of sea urchins.

Structure and antiviral activity of sulfated fucans from Stoechospermum marginatum
Phytochemistry, 2006 A sulfated fucan containing fraction (SmWE) was isolated from water extract of the brown seaweed Stoechospermum marginatum collected from the Arabian Sea. Anion exchange chromatography of the crude fraction results in the production of a sulfated fucan (F3) having a molecular mass of 40 kDa and specific rotation [alpha]D(30) - 124 degrees (c 0.5, H2O).

Is there a correlation between structure and anticoagulant action of sulfated galactans and sulfated fucans? [PDF]
Glycobiology, 2002 We attempted to identify the specific structural features in sulfated galactans and sulfated fucans that confer anticoagulant activity. For this study we employed a variety of invertebrate polysaccharides with simple structures composed of well-defined units of oligosaccharides.
