On the other hand, DPPIV mediated cleavage of the N-terminal His-Ala or Tyr-Ala dipeptides from circulating incretin hormones like, glucagon-like peptides (GLP)-1 and -2, gastric inhibitory polypeptide (GIP), all members of the enteroglucagon/GRF superfamily, results in their biological inactivation in vitro and in vivo.

In this study, we explored whether DPP-4 inhibition by valine-pyrrolidide (val-pyr; 100 micromol/kg administered through gastric gavage at t = -30 min) affects the insulin and glucose responses to iv glucose (1 g/kg) together with GLP-1 (10 nmol/kg), glucose-dependent insulinotropic polypeptide (GIP; 10 nmol/kg), pituitary adenylate cyclase-activating polypeptide 38 (PACAP38; 1.3 nmol/kg), or gastrin-releasing peptide (GRP; 20 nmol/kg) given at t = 0 in anesthetized C57BL/6J mice.

The results reveal that glycation of the N-terminus of GLP-1 or GIP stabilized both peptides against DPP-IV degradation.

Dipeptidyl peptidase-IV (DPP-IV) is an enzyme responsible for the inactivation of the glucoregulatory incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).

In addition to their insulinotropic actions, GLP-1 and GIP also promote beta-cell proliferation and survival, and DPP-IV inhibitors exert similar effects in rodent type 2 diabetes models.

This study evaluated the effects of nateglinide on dipeptidyl peptidase-IV (DPP-IV) activity and glucose-dependent insulinotropic polypeptide (GIP) degradation.

Two drug classes-namely, the injectable glucagon-like peptide 1 (GLP-1) receptor agonists, which produce pharmacological GLP receptor activity, and the oral dipeptidyl peptidase-4 (DPP-4) inhibitors, which raise levels of endogenously produced GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) by preventing enzymatic degradation--have been available for several years.

Dipeptidyl peptidase-4 (DPP-4) inhibitors, such as sitagliptin, increase active GLP-1 and GIP levels and improve hyperglycemia in a glucose-dependent fashion.

Since the launch of sitagliptin in 2006, a compelling body of evidence has accumulated showing that dipeptidyl peptidase-4 (DPP-4) inhibitors, which augment endogenous GLP-1 and GIP levels, represent an important advance in the management of T2DM.

Two new drug classes based on the actions of the incretin hormones have been approved for therapy of type 2 diabetes: injectable long-acting stable analogs of GLP-1, incretin mimetics, and orally available inhibitors of dipeptidyl peptidase 4 (DPP4; the enzyme responsible for the rapid degradation of GLP-1 and GIP), the so-called incretin enhancers.

The increased peak glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) response to oral glucose after GBP did not correlate with DPP-4 activity.

GLP-1, GIP, Liraglutide, N-AcGIP(Lys(37)Myr) (N-acetylGIP with myristic acid conjugated at Lys(37)), a simple combination of both peptides and a Lira-AcGIP preparation [overnight preparation of Liraglutide and N-AcGIP(Lys(37)Myr)] were incubated with DPP-IV (dipeptidyl peptidase-IV) to assess peptide stability, and BRIN-BD11 cells were used to evaluate cAMP production and insulin secretion.
