摘要： The present invention relates to novel tocopheryl oligosaccharides, acylated tocopheryl oligosaccharides, sulfated tocopheryl oligosaccharides, and antiviral agents including the sulfated tocopheryl oligosaccharides as active ingredients. In the tocopheryl oligosaccharide, the hydrogen atom of the hydroxy group at the 1-position in the terminal sugar moiety of an oligosaccharide which consists of 3 ∼ 20 of identical or different repeating monosaccharide units selected from the group consisting of glucose, galactose, mannose, talose, idose, altrose, allose, glucose, xylose, arabinose, rhamnose, fucose, and fructose, which are glycoside-linked, is substituted by a tocopherol group. In the acylated tocopheryl oligosaccharides, each of any hydroxy group of the sugar moiety, other than the hydroxy group at the 1-position in the terminal sugar moiety of the oligosaccharide described above, is protected by an acyl group. The antiviral agents including the sulfated tocopheryl oligosaccharides or the biologically acceptable salt of the same as active ingredients have low toxicities and exhibit improved antiviral action, especially against the Human Immunodeficiency Virus.

摘要： A oligosaccharide aromatic glycoside sulfate or a physiologically acceptable salt of the same which is formed from same or different monosaccharides bonded by glycoside bonds, wherein the hydrogen atom in the hydroxyl group at the position-1 carbon atom at the terminal of the oligosaccharide is substituted with a group represented by Formula (I):
        - Y - (O) n - R   (I)
(in the formula, R represents an alkyl group having 1-18 carbon atoms, n is 0 or 1, O represents an oxygen atom, and Y represents an allylene group) and at least 10% of the remaining hydroxyl groups of the sugar subunits have been subjected to sulfated esterification; an anti-viral agent containing this oligosaccharide aromatic glycoside sulfate or physiologically acceptable salt of the same as an active component; and a oligosaccharide aromatic glycoside which functions as a production intermediate are disclosed. The anti-viral agent exhibits low toxicity and superior anti-viral activity, and is especially effective against viruses which are known to cause AIDS.
