Metabolites of Seaweeds as Potential Agents for the Prevention and Therapy of Influenza Infection.

Context: Seaweed metabolites (fucoidans, carrageenans, ulvans, lectins, and polyphenols) are biologically active compounds that target proteins or genes of the influenza virus and host components that are necessary for replication and reproduction of the virus.

Objective: This review gathers the information available in the literature regarding to the useful properties of seaweeds metabolites as potential agents for the prevention and therapy of influenza infection.

Materials And Methods: The sources of scientific literature were found in various electronic databases (i.

Radioprotective properties of Cumaside, a complex of triterpene glycosides from the sea cucumber Cucumaria japonica and cholesterol.

The radioprotective activity has been studied of a new immunomodulatory lead material, Cumaside, which is a complex of monosulfated triterpene glycosides from the edible sea cucumber Cucumaria japonica and cholesterol. Female CD-1 strain mice administered with prophylactic doses of Cumaside were irradiated using a Gamma-therapeutic device with a 60Co source (exposure dose 6.5 Gy, dose rate 1.

Molecular characterization and therapeutic potential of a marine bacterium Pseudoalteromonas sp. KMM 701 alpha-galactosidase.

An alpha-galactosidase capable of converting B red blood cells into the universal blood type cells at the neutral pH was produced by a novel obligate marine bacterium strain KMM 701 (VKM B-2135 D). The organism is heterotrophic, aerobic, and halophilic and requires Na+ ions and temperature up to 34 degrees C for its growth. The strain has a unique combination of polysaccharide-degrading enzymes.
