Synthesis and characterisation of novel glycoclusters based on cell penetrating heptakis(6-aminoethylamino-6-deoxy)-β-cyclodextrin

Original article

Abstract

The modification of a polyamino βCD, heptakis(6-aminoethylamino-6-deoxy)-βCD (bpen) with several monosaccharides (Man, GlcNAc, Gal, Glc), specific for bacterial lectin targeting is described. The first synthetic approach, based on disuccinimidyl carbonate-substituted monosaccharides had moderate success, whereas the second approach, based on thiopropanoic acid-linked monosaccharides, was more efficient. Each method gave the best result with a different monosaccharide. Given that bpen is known to penetrate cells, the new products are expected to possess both lectin recognition ability and membrane crossing properties.
