Xylomannan

Structural description

The red seaweed Nothogenia fastigiata synthesizes a complex system of polysaccharides comprising neutral xylans of the β-D-(1-3), β-D-(1-4)-mixed linkage type, sulfated xylo-galactans of the agaroid type and a family of sulfated xylomannans. These polysaccharides are α(1-3)-linked O-mannans with position 2- and 6-sulfated. The main mannose backbone has β-D-(1-2)-linked O-xylose side chains.

Activities and Uses

Antiviral activity, Herpes simplex virus type 1 and 2 in vitro activity: inhibits replication of Herpes simplex (HVS) 1 and 2, human cyclomegalovirus (HCLV), respiratory syncytial virus (RSV), Influenza A & B, Junin virus, Tacaribe, Simian virus (P. Mandal et al., 2008. Phytochem., vol. 69, 2193–2199).

Xylomannan is a newly discovered antifreeze molecule, found in the freeze-tolerant Alaskan beetle Upis ceramboides (Walters KR Jr et al., 2009. PNAS; 106 (48):20210-5).
