Synthesis and immunological evaluation of MUC1 glycopeptide conjugates bearing: N -acetyl modified STn derivatives as anticancer vaccines

Glycoprotein MUC1 is an attractive target for anti-tumor vaccine development. However, the weak immunogenicity of MUC1 remains a significant problem. To solve this problem, several STn derivatives with N-acetyl modifications were synthesized and incorporated into a 20-amino acid MUC1 tandem repeat sequence. The modified STn-MUC1 glycopeptides were further connected to a carrier protein keyhole limpet hemocyanin (KLH). The immunological effects of these synthetic vaccine conjugates were evaluated using the BALB/c mouse model. The results showed that vaccine V2 elicited higher titers of antibodies which cross-reacted with the native STn-MUC1 antigen. Moreover, the elicited antisera reacted with the STn-MUC1 antigen-positive tumor cells, indicating that the carbohydrate antigen modification strategy may hold potential to overcome the weak immunogenicity of natural MUC1 glycopeptides.

Synthetic Glycopeptides of the Tandem Repeat Sequence of the Epithelial Mucin MUC4 with Tumour-associated Carbohydrate Antigens

Glycohexadecapeptides representing the tandem repeat sequence of the epithelial mucin MUC4 were prepared by applying a solid-phase methodology. The required glycosyl amino acid building blocks containing the tumour-associated saccharide antigens TN/

The (2-Phenyl-2-trimethylsilyl)ethyl-(PTMSEL)-Linker in the Synthesis of Glycopeptide Partial Structures of Complex Cell Surface Glycoproteins

The (2-phenyl-2-trimethylsilyl)ethyl-(PTMSEL) linker represents a novel fluoride-sensitive anchor for the solid-phase synthesis of protected peptides and glycopeptides. Its cleavage is achieved under almost neutral conditions using tetrabutylammonium fluo
