We are synthetic chemists developing vaccines and adjuvants to treat viral infection and cancer. Our research is focused on creating experimental methods for the efficient conjugation of site-specific functionalized peptides as vaccine candidates. In an effort to improve avidity and bioavailability, peptides directed against neutralizing antibodies have been successfully multimerized using a 1-3 dipolar cyclization strategy. Our central contributions involve introduction of a trialkyne functionality onto rigid scaffolds that promote the cyclization process. The synthesis of glycolipid natural products complements the vaccine design program. One-pot synthetic routes for large quantity production of alpha-galactosyl ceramides, cholesteryl glycosides and glycerol containing glycolipds using glycosyl iodide chemistry have been established. This synthetic chemistry platform exploits the unique reactivity of glycosyl iodides providing highly efficient routes to immunostimulatory glycolipids for adjuvant therapy. Further developments in step-economy synthesis of tumor associated carbohydrate antigens (TACAs) have been achieved using Regioselective Silyl Exchange Technology (ReSET); a synthetic process, which minimizes the need for elaborate protecting group strategies to build complex oligosaccharides. Instead, per-O-silylated sugars undergo selective exchange of silicon protecting groups giving orthogonally protected carbohydrate building blocks in as few as two steps. Integration of the ReSET strategy with the unique reactivity of glycosyl iodides provides a powerful platform for glycolipidomic profiling.
