Abstract
The development of new cleavable linkers increases the diversity of compatible conditions for peptide discovery platforms. Potential applications for these linkers include high-throughput pharmaceutical candidate screening when utilized in Peptide Encoded Libraries (PELs). This thesis describes the development of a bifunctional diaryl oxazole-based cleavable linker that may be incorporated into compounds through Solid-Phase Peptide Synthesis (SPPS). This oxazole-based linker may be rapidly cleaved by cerium ammonium nitrate in aqueous conditions and is compatible with most natural amino acids and a variety of unnatural amino acids. This linker represents the first single-electron oxidant labile linker described to our knowledge and it demonstrates orthogonal cleavage to traditional oxidatively cleaved linkers. A greater diversity of cleavable linkers increases the versatility of various peptide discovery platforms and oxazole-based linkers demonstrate novel mechanisms for the mild oxidative release of attached compounds.
