<p>The invention involves a kind of oligosaccharides and their sulfates. The backbone of the oligosaccharides is consisting of 3 to 14 sugar residues, and the side chains are consisting of 0 to 4 sugar residues. There is at least one 1 →α linkage in the backbone. This invention also involves the dendrimers that are combined by polyhydroxyl compounds. These oligosaccharides, their sulfates and dendrimers have immune enhancing, antitumor, and antiviral activities. They can be used in the preparation of immune enhancing, antitumor, and antiviral medicine.</p> |
