| Research Abstract |
We have given attention to oligosaccharide chains as the key parti,cipants in cell-cell recognitions of various biological events. Well-defined polymers having oligossaccharide chains should serve as cellーspecific biomedical materials. Following six types of polymers having galactose, mannose, N-aceylglucosamine, and glucose residues as recognition markers have been synthesized.
(1) Oligomers of lactose-substituted styrene monomer. Via radical telomerization.
(2) Homopolymer of N-acetylchito-oligosaccharide substituted styrene. Via redical polymerizaton of macromonomer.
(3) Star-type graft copolymers. Via radical polymerization of macromer from sugar-carrying methyl=methacrylate monomer.
(4) Comb-shaped branched polysaccharides, 4-O-(alpha-D-mannopyranosyl)-(1->6)-alpha-D-mannopyranan. Via ring-opening polymerization of anhydro disaccharide derivatives.
(5) (1->6)-beta-D-Galactopyranan. Via steric control by neighboring-group participation in ring-opening polymerization.
(6) Oligosaccharide-carrying polypeptides. Via polymeric reaction of poly (L-glutamic acid).
