Abstract

Oligosaccharides including those usable as anti-inflammatory agent or anti-allergy agent, represented by the following general formula (3): wherein R10 and R11 each independently represent a hydrogen atom or —SO3M where M represents a proton or a monovalent cation, Ac represents an acetyl group, R12 represents a hydrogen atom or an anomeric substituent (a 6-O-sulfated N-acetylglucosamine residue, an alkyl group, a glycerol residue, an O-alkylglycerol residue, a cholesterol residue, a cholestanyl group, a ceramide residue, a phospholipid residue, a biotin residue, or a peptide residue), and Z represents an oxygen atom or —NHCO—.
