Sulfated galactans

Marine sulfated polysaccharides (MSPs), such as sulfated fucans (SFs), sulfated galactans (SGs), and glycosaminoglycans (GAGs) isolated from invertebrate animals, are highly anionic polysaccharides capable of interacting with certain cationic proteins, such as... [Pg.195]

In addition to valuable physicochemical properties, sulfated polysaccharides of the red algae are promising biologically active polymers, and many structural works already cited aimed at isolation and characterization of new compounds having potential medical application. The most important types of biological activity of sulfated galactans are listed briefly in this section. [Pg.169]

Sulfated galactans may interact with numerous regulatory proteins affording inhibition of complement activation, of tumor cell adhesion to P-selectin, of several matrix-degrading enzymes, and so on.668-670 These features depend strongly on the... [Pg.170]

Some sulfated galactans, or products of their partial depolymerization, exhibit antioxidant activity.684,685 The chemistry of radical scavenging effects is not very clear, especially taking into account the fact that several products of chemical modifications of natural polysaccharides, such as oversulfated, phosphorylated, acety-lated and phthaloylated derivatives, may demonstrate stronger antioxidant activity than the raw material.685-688...
