The antimicrobial peptide tachyplesin I was used as a model to apply the title strategy, which was developed for the preparation of peptidic macrocycles with double disulfide surrogates. The folding and activity of the tachyplesin I analogues were found to be sensitive to the structure of the disulfide surrogates, thus underlining the necessity of a flexible synthetic route for generating disulfide

Solid-phase incorporation of diaminodiacids is one of the most effective approaches for synthesis of peptidedisulfidebondmimics. One of a limitation of current diaminodiacid toolbox is that only four-atom linkage mimics are available that may not fully meet the activity optimization requirement. In this work, we developed a new diaminodiacid that contains a five-atom thioether (C–C–S–C–C) bridge

essential for the structural stability and biological activity of many bioactive peptides. However, these bonds are labile to reducing agents, which can limit the therapeutic utility of such peptides. Substitution of a disulfide bond with a reduction-resistant cystathionine bridge is an attractive means of improving stability while imposing minimal structural perturbation to the peptide. We have applied

The synthesis of N-Fmoc-O-(N'-Boc-N'-methyl)-aminohomoserine in 35% overall yield from L-homoserine is described. This amino acid can be efficiently incorporated into peptides using Fmoc-chemistry-based solid-phase peptide synthesis, and the resulting peptides can be chemoselectively glycosylated at the aminooxy side chains to generate neoglycopeptides. The synthesis of this derivative greatly expands the availability of a previously developed neoglycopeptide synthesis strategy.
