“A sulfated polysaccharide from Monostroma nitidum Wittrock (Ulvophyceae)” was purified by anion-exchange and gel filtration column chromatographies. The isolated polysaccharide consisted of large amount of l-rhamnose with small amount of d-glucose, and it was regarded to be a rhamnan sulfate ...detailed
Rhamnan sulfate from cell walls of Monostroma latissimum was purified through subsequent chromatographic systems. The purified polysaccharide consisted of large amounts of rhamnose residues and appeared to be an entire homopolysaccharide. Antithrombin activity was lower than rhamnan sulfate prev...detailed
A low molecular weight fraction, designated LMWP, was prepared by mild acid hydrolysis of sulfated rhamnan from Monostroma latissimum and purified by anion-exchange and gel-permeation chromatography. Chemical and spectroscopic analyses showed that LMWP was mainly composed of rhamnose, and its mo...detailed
Polysaccharide from Monostroma latissimum PML is a sulfated rhamnan, which consists of →3)-α-L-Rhap-(1→ and →2)-α-L-Rhap-(1→ residues with partial branches and sulfate groups at C-2 of →3)-α-L-Rhap-(1→ and/or C-3 of →2)-α-L-Rhap-(1→. The anti-enterovirus 71 (EV71) activity in vitro o...detailed
A concise synthetic route to rhamnan oligosaccharides with alternating α-(1→2)/(1→3)-linkages and repeating α-(1→3)-linkages is reported. This synthesis was achieved by iterative α-glycosylation using disaccharide building blocks and through orthogonal coupling between thioglycosides of L-...detailed
