Herein, we detail several specific challenges that hinder the effective synthesis of glutamyl hydrazide containing peptides, and we describe a synthetic strategy to work around these challenges. Glutamyl hydrazide is an unnatural amino acid residue that bears an acyl hydrazide functional group on its side chain. This family of compounds has the potential to provide potent and selective inhibitor molecules

human and bovine serum. When the amino group is present on a pyrimidine or purine ring, the dipeptide derivatives are chemically unstable, whereas the tetrapeptide derivatives (i.e., ValProValPro or ValAlaValPro) were much more stable in solution and efficiently converted to the parent drug by the action of DPPIV/CD26. This DPPIV/CD26-directed prodrug technology can be useful to increase solubility of
