Biochem/physiol Actions

Sitagliptin is an orally active, potent and selective dipeptidyl peptidase IV (DPP4; DPP-IV) inhibitor (IC50 = 18 nM) with excellent selectivity over other proline-selective peptidases (IC50 = 48 μM/DPP8, >100 μM/DPP9 & QPP). Sitagliptin improves glucose tolerance in lean mice (23% and 55% reduction of blood glucose post 5 g dextrose/kg with 0.1 or 3 mg Sitagliptin/kg p.o. 60 min prior to dextrose challenge) and in DIO mice (68% and 90% reduction of blood glucose post 2 g dextrose/kg with 0.3 or 3 mg Sitagliptin/kg p.o.) as a result of DPP-IV inhibition and upregulated GLP-1 level in blood in vivo.

Diabetic nephropathy, a major threat to diabetic patients, is considered as the main reason for end-stage renal disease. Fortunately, incretin-based therapy has been aroused as considerable source to attenuate diabetic renal damage. This study aimed to investigate whether superior protective

Tyrosine kinase inhibitors (TKIs) are used as targeted drugs for advanced renal cell carcinoma (RCC), although most cases eventually progress by acquiring resistance. Cancer stemness plays critical roles in tumor aggressiveness and therapeutic resistance, and dipeptidyl peptidase IV (DPP4) has

A novel series of beta-amino amides incorporating fused heterocycles, i.e., triazolopiperazines, were synthesized and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-IV) for the treatment of type 2 diabetes.

We previously tested two angiotensin-converting enzyme (ACE) inhibitors and two dipeptidyl peptidase-4 (DPP-4) inhibitors for dual enzyme inhibitory effect. Only two DPP-4 inhibitors, linagliptin and sitagliptin, were able to inhibit ACE. In the present study, we investigated if other inhibitors

Cancer has been as one of common comorbidities of diabetes. Long-term antidiabetic treatment may potentially exert uncertain impacts on diabetic patients with cancer including breast cancer (BC). Dipeptidyl peptidase-4 inhibitors (DPP-4i) are currently recommended by the AACE as first-line hypoglycemic
