| Name | Teneligliptin |
| Description | Teneligliptin (MP-513) is a novel dipeptidyl peptidase 4 (DPP IV) inhibitor for the treatment of type 2 diabetes mellitus with hypoglycemic activity for the study of obesity and diabetes. |
| Kinase Assay | DPP-4 inhibition assay is carried out using either 5 ng purified recombinant human DPP-4 (rhDPP-4), human plasma (20-fold diluted with assay buffer; phosphate-buffered saline (PBS) containing 0.003% Brij-35 solution), or rat plasma (10-fold diluted with assay buffer) Gly-Pro-MCA as a chromogenic substrate as described previously with slight modifications. DPP-4 inhibitors (Teneligliptin, Sitagliptin, and Vildagliptin) are diluted with assay buffer at several concentrations. Twenty microliters of inhibitor solution, 20 μL of the enzyme source, and 20 μL of Gly-Pro-MCA (final concentration, 25 μM) are mixed with 140 μL or 160 μL of assay buffer to initiate the enzyme reaction. After 20 min (rhDPP-4) or 1 h (plasma) at 37°C, the fluorescence intensity of 7-amino-4-methyl-coumarin (AMC) generated from Gly-Pro-MCA is measured using an automated microplate reader at 360 nm excitation and 465 nm emission. The fluorescence intensity of AMC corresponded to DPP-4 activity[1]. |
| In vitro | Teneligliptin inhibits DPP-4 enzyme in a concentration-dependent manner. The IC50 values of Teneligliptin on human recombinant DPP4 (rhDPP-4), human plasma and rat plasma were 0.889 nM, 1.75 nM and 1.35 nM, respectively. The kinetics of enzyme inhibition by Teneligliptin was investigated using Gly-Pro-MCA as the substrate and rhDPP-4 as the enzyme source, and the Ki, Km and Vmax values were 0.406 nM, 24 μM and 6.06 nmol/min, respectively. Teneligliptin inhibited the degradation of GLP-1(7-36)amide with an IC50 value of 2.92 nM. [1] |
| In vivo | In Wistar rats, oral administration of Teneligliptin effectively inhibited plasma DPP-4 with an ED50 value of 0.41 mg/kg, and the inhibitory effect was sustained up to 24 hours after administration.
Teneligliptin at a dose of 1 mg/kg significantly reduced triglyceride and free fatty acid fluctuations in an oral fat loading assay in Zucker rats. Zucker rats receiving Teneligliptin orally for two consecutive weeks demonstrated a reduction in blood glucose fluctuations in an oral glycemic load test, as well as a reduction in plasma triglyceride and free fatty acid levels in the non-fasting state. [1]
In addition, Teneligliptin improved hepatic histopathological features and reduced intrahepatic triglyceride levels in a mouse model of nonalcoholic fatty liver disease, which was associated with downregulation of hepatic lipid synthesis-related genes induced by AMPK activation. [2] |
