A new strategy was developed for the synthesis of peptide disulfide-bond mimics using fully orthogonally protected diaminodiacids. This method overcomes the previous problems of heavy-metal contamination and poor compatibility with Fmoc chemistry and provides a practical avenue for the efficient preparation of peptide disulfide-bond mimics.

N′-methyl-aminooxy aminoacid has been designed, synthesized, and successfully incorporated into peptides using standard solid-phase peptidesynthesis procedures. Reaction of these peptides with native reducing sugars yields neoglycopeptides via a chemoselective reaction with the aminooxy side chains. The key feature of the new aminoacid is that it maintains attached sugars in their cyclicconformations and close

-based glyoxalaseIinhibitors culminated in the discovery of the first single-digit nanomolar inhibitor. This study makes available key information about possible means to address the issues of metabolic instability, low potency, and synthetic complexicity that have plagued the area of glyoxalaseI inhibition. Knowledge garnered from this study has implications in the design of inhibitors with higher

N-alkylaminooxy amino acids have been synthesized in 22-56% overall yield from readily available amino acid precursors. Each amino acid can be efficiently incorporated into peptides using Boc-chemistry-based solid-phasepeptidesynthesis, and in three of the four cases the resulting peptides can be chemoselectively glycosylated at the aminooxy side chains to generate neoglycopeptides. The range of N-alkylaminooxy
