Convergent synthesis of fluorescein-labelled lysine-based cluster glycosides
摘要:
The synthesis of fluorescein-labelled lysinyl trees, containing 2, 4 or 8 manno- or galactoside residues, is reported. These lysine-based cluster glycosides have been readily assembled by coupling amino-functionalized, N-chloroacetylated-L-lysinyl trees with fluorescein-isothiocyanate (FITC) and performing a thioether chemoselective ligation with fully deprotected glycoside derivatives. The reaction order is governed by the size of the lysinyl trees; the labelling/thioetherification steps can be performed in an one pot procedure, thus allowing an easy access to glycodendrimers designed to study the dendritic cells' mannose receptor.

histocompatibility class II antigens have been bound to clustered glycosides for selective targeting of the dendritic cell mannose receptor. Di-, tetra-, and octavalent glycoside-antigen conjugates have been obtained after two, orthogonal, hydrazone/thioether ligations, performed by using thio derivatives of D-mannose, D-galactose, or D(-)-quinic acid, glyoxylyl (or hydrazino)-N-chloroacetylated lysinyl
