Abstrakt: We presented the structure of the polysaccharide moiety and anticancer activity in vitro of the sulfated lipopolysaccharide isolated from the marine bacterium Cobetia litoralis KMM 3880(T). The structure of O-polysaccharide was investigated by chemical methods along with (1)H and (13)C NMR spectroscopy. The O-polysaccharide was built up of branched trisaccharide repeating units consist of D-glucose (D-Glcр), D-mannose (D-Manр) and sulfated 3-deoxy-d-manno-oct-2-ulosonic acid (Kdo5S): →7-β-Kdoр4Ac5S-(2→4)-[β-d-Glcp-(1→2)-]-β-d-Manр6Ac-1→. We demonstrated that the lipopolysaccharide and О-deacetylated O-polysaccharide from Cobetia litoralis KMM 3880(T) inhibited a colony formation of human melanoma SK-MEL-28 and colorectal carcinoma HTC-116 cells.
