Simple separation of anticoagulant sulfated galactan from marine red algae
Journal of Applied Phycology, 2008In this study, hot water extracts of 22 red algal species were evaluated for their potential anticoagulant activities. The extracts from eight species (Grateloupia elliptica, Sinkoraena lancifolia, Halymenia dilatata, Grateloupia lanceolata, Lomentaria catenata, Martensia denticulata, Schizymenia dubyi, Chondrus crispus) showed potent activated partial

Sulfated galactans from the red seaweed Nothogenia fastigiata (Nemaliales, Rhodophyta)
Hydrobiologia, 1990Fractionation of the cetrimide salts of the sulfated polysaccharides of Nothogenia fastigiata led to the isolation of a complex galactan sulfate. This product showed compositional and molecular weight heterodispersion together with composition-, temperature-, time-, and conformation-dependent molecular associations.

The anti-HMPV (human metapneumovirus) activity was determined for sulfated dl-hybrid galactans obtained from the red seaweed Cryptonemia seminervis and their depolymerized products obtained by reductive partial hydrolysis. Structural studies carried out in three homogeneous depolymerized fractions DS-1, DS-2e and DS-3 (Mw of 51.6-63.8 kDa) showed that ...

The sulfated galactans (SG) of mass 16 kDa was purified from S.hypnoides through anion exchange and gel permeation chromatography. The biochemical properties of SG including carbohydrate, 3,6 anhydrogalactose, sulfate, uronic acid, moisture, ash, carbon, hydrogen, nitrogen contents were estimated.

SummaryWe compared sulfated galactans (SGs) from two species of red algae using specific coagulation assays and experimental models of thrombosis.These polysaccharides have an identical saccharide structure and the same size chain, but with slight differences in their sulfation patterns.As a consequence of these differences, the two SGs differ in their

The cell-wall of Botryocladia occidentalis (Rhodophyta) contains sulfated galactans (BoSGs) with anti- and procoagulant properties, but their effects on thrombin generation (TG) were fewer explored. This study evaluated BoSGs by different extraction times (3, 6, 16 or 24 h) on yield, physical-chemical features and in vitro effects on cephalin-induced ...
