Cancer vaccines are based on a vaccinology strategy whereby the patient's immune system is harnessed to induce a specific immune response to kill cancer cells and comprises two categories: prophylactic and therapeutic. Glycoprotein mucin 1 (MUC1), which is overexpressed and poorly glycosylated on cancer cells, is one of the most promising candidates for the development of new cancer vaccines. However, it should be noted that mucin-like glycopeptides are poorly immunogenic and unable to elicit effective and long-lasting immune responses. Therefore, MUC1-derived tumor antigens need to be conjugated with immune activators. This review focuses on the synthesis of MUC1 glycopeptides, provides an overview of recently advanced designs of vaccines based on MUC1, and compares the advantages and disadvantages of the various strategies devised to date.
Keywords: Glycopeptide synthesis; MUC1; cancer vaccine; multicomponent; multivalent.
