Inhibitory effect of sulfated galactans from the marine alga Bostrychia montagnei on herpes simplex virus replication in vitro [PDF]
Phytomedicine, 2001 Sulfated polysaccharides exhibit many biological properties such as antiviral and anticoagulant activities. Herein, we report the antiviral activity of sulfated galactans extracted from the red sea-weed Bostrychia montagnei against herpes simplex virus ...

Immunostimulating effects of a sulfated galactan from Codium fragile
Carbohydrate Research, 2010A pyruvylated sulfated galactan from Codium fragile is a highly ramified polysaccharide consisting of 3-linked, 3,6-linked, and non-reducing terminal d-galactose with pyruvate and sulfate groups; the glycan exerts anti-herpes simplex virus type 2 effects in vitro and in vivo.

The discovery of sulfated galactans and sulfated fucans in marine invertebrates with simple and ordered structures opened new perspectives to investigate the biological activity of these molecules and to determine whether different structures confer high affinity for a particular protein. We undertook a conformational analysis of a 2-sulfated, 3-linked

The structure of a galactan sulfate from the red seaweed Bostrychia montagnei
Carbohydrate Research, 2002The sulfated, methylated galactan isolated from the red seaweed Bostrychia montagnei, showed an unusually narrow structural dispersion. This agaran has the defining linear backbone of alternating 3-linked beta-D-galactopyranosyl units and 4-linked alpha-L-galactopyranosyl and 3,6-anhydrogalactopyranosyl residues.

Polysaccharides from the red seaweed Gracilaria fisheri possess many functions, which include antioxidant, antiviral, and antibacterial activities. However, detailed data on their immunomodulatory activities are scarce. Here, we isolated sulfated galactans (SG) from G. fisheri. We found that the predominant SG from G.

Sulfated galactan is a catalyst of antithrombin-mediated inactivation of α-thrombin
Biochimica et Biophysica Acta (BBA) - General Subjects, 2008Novel compounds presenting anticoagulant activity, such as sulfated polysaccharides, open new perspectives in medicine. Elucidation of the molecular mechanism behind this activity is desirable by itself, as well as because it allows for the design of novel compounds.

A precipitation reaction between certain human G immunoglobulins and sulfated galactans
Immunochemistry, 1971Abstract During electrophoresis, some pathological sera are seen to precipitate spontaneously in an agar gel and not in an agarose gel. Such sera come from G myelomas or malignant lymphomatosis cases. A similar precipitation is observed when either agaropectin or other sulfated galactans (but not other sulfated polysaccharides) are added to the same ...

A new sulfated β-galactan from clams with anti-HIV activity
Carbohydrate Research, 1999A new polysaccharide composed of galactan sulfate with a beta-(1-->3)-glycosidic linkage has been isolated from the marine clam species Meretrix petechialis. The polysaccharide was homogeneous in its composition containing D-galactose. The glycosidic linkage was examined by 2D DQF-COSY and 2D NOESY spectroscopy. The coupling constant of anomeric proton

Structural and functional insights into sulfated galactans: a systematic review
Glycoconjugate Journal, 2009Sulfated galactans (SGs) are highly anionic marine galactose-composed homopolysaccharides. Although their structures vary among species, their main features are conserved among phyla. Green algal SGs are quite heterogeneous, although preponderantly composed of 3-beta-D-Galp units.
