ABSTRACT:
Peptide inhibitors of dipeptidyl-aminopeptidase type IV (DP-IV) are provided. The peptide inhibitors have an isomeric purity of about 96–99 percent. The peptide inhibitors include one or more amino acids covalently coupled to boroproline moiety. The compounds are useful as DP-IV inhibitors, in vivo and in vitro.
