Definition

A synthetic oligosaccharide derivative in which three beta-D-Gal-(1->4)-beta-D-Glc-(1->6)-[beta-D-Gal-(1->4)]-beta-D-GlcNAc tetrasaccharide units are linked through N-pentylpentanamide linkers, with a 5-aminopentyl spacer group attached to the GlcNAc residue within the terminal unit. Synthesised as a spacer-bridged oligosaccharide mimic of the capsular polysaccharide of Streptococcus pneumoniae serotype 14, the 5-aminopentyl spacer group affords a method of linking to the CRM197 carrier protein, a genetically detoxified form of diphtheria toxin.
