W. Zou et al., Construction of multivalent sialyl Le(x) from the type Ia group B Streptococcus capsular polysaccharide, CARBOHY RES, 332(3), 2001, pp. 249-255
The type Ia group B Streptococcus (GBSIa) capsular polysaccharide was speci
fically degraded by partial Smith oxidation of 2,3-diol of the Glc in the b
ackbone to fragments representing asialo core repeating units. Sialylation
of these oligomers furnished GBSIa multiple repeating units. One, two and t
hree repeating units of GBSIa were obtained pure, and the higher oligomers
were obtained as mixtures. After enzymatic fucosylation oligosaccharides ca
rrying bivalent, trivalent and other multivalent sialyl Le(x) epitopes pres
ented as appendages on an oligolactoside scaffold were obtained. (C) 2001 E
