Abstract

Branched polysaccharides having D-mannopyranose, D-arabinofuranose, or oligo-D-arabinofuranose side-chains were synthesized by the reaction of 3,4,6-tri-O-acetyl-(1,2-O-ethylorthoacetyl)-beta-D-mannopyranose, 3,5-di-O-benzoyl-(1,2-O-ethylorthobenzoyl)-beta-D-arabinofuranose, or 3-O-benzoyl-(1,2,5-O-orthobenzoyl)-beta-D-arabinofuranose with cellulose acetate or curdlan acetate, followed by desterification. The structure and antitumor activity of the water-soluble portion of the polysaccharides thus obtained were investigated. Polysaccharides synthesized from (1----3)-beta-D-glucan as the main chain with oligo-D-arabinofuranose side-chains exhibited high antitumor activity.
