  α-Galactose based neoglycopeptides. Inhibition of verotoxin binding to globotriosylceramide

  摘要：

  Solution and solid phase strategies for the synthesis of a-galactose based neoglycopeptide derivatives 2-13 were developed. Neoglycopeptides generated were tested for the inhibition of verotoxin binding to globotriosylceramide (Gb3) using ELISA. Among all of the compounds tested, only the lipid derivatives of neoglycopeptides, 11, 12 and 13 were found to be inhibitors, IC50 = 2.0 mM (11b and 12c) and 0.2 mM (11c and 13c). All of the inhibitors (11b, 11c, 12c and 13c) have a similar branching of the two alpha-galactosyl units at the N-terminal glycine residue of a short peptide and a lipid moiety attached at the C-terminal site. Both of these factors seem to be crucial for the inhibition. It is interesting to note that the inhibitors have only a portion of the natural trisaccharide ligand. The secondary groups either may contribute in sub-site oriented interactions with the protein receptors or may mimic the internal sugar units of the cell-surface ligand, Gb3.

  Stereoselective synthesis of neo-C-glycopeptide building blocks: Towards a flexible and control-oriented design as probes for carbohydrate-protein interactions

  摘要：

  Neo-C-glycopeptides (1-4) have been synthesized as building blocks to obtain higher neo-C-glycopeptides as probes for studying carbohydrate-protein interactions. A convergent approach for the synthesis of 4 has been developed, in which two galactose units are attached to a glycine derivative in a stepwise procedure (reductive amination followed by amide coupling) and finally coupling to the protected dipeptide having a free amino group on the side chain.
