Protocol

Kinase experiment:

The enzyme kinetic analysis of gemigliptin on DPP-4 is performed using a continuous spectrophotometric assay with the substrate Gly-Pro-pNA. Briefly, inhibition of DPP-4 activity is determined by measuring the absorbance (at 390 nm) resulting from the cleavage of the substrate Gly-Pro-pNA by the DPP-4 enzyme under steady-state conditions. Enzyme activity is defined as the slope (in mOD/ min) from 5 to 15 min. The inhibition pattern is evaluated using a Lineweaver-Burk plot, and the Ki is determined using a curve- fitting program[2].

Animal experiment:

Mice[1]Seven week-old male C57BL/KsJ-db/db mice and their lean littermates (db/þ, normal) are randomly assigned to three (n=10) groups. One group of db/db mice is orally administered gemigliptin (100 mg/kg body weight) and another group is administered the same amount of vehicle via oral gavage for 12 weeks. Non-diabetic littermates receive the same vehicle treatment. Blood glucose level and body weight are measured weekly[1].

Background

Gemigliptin is a highly selective dipeptidyl peptidase 4 (DPP4) inhibitor with a KD of 7.25 nM.

In in vitro assay, gemigliptin dose-dependently inhibits methylglyoxal-modified AGE-bovine serum albumin (BSA) formation (IC50=11.69 mM). AGE-collagen cross-linking assays shows that gemigliptin has a potent inhibitory effect (IC50=1.39 mM) on AGE-BSA cross-links to rat tail tendon collagen. In addition, gemigliptin directly traps methylglyoxal in a concentration-dependent manner[1]. Gemigliptin is a reversible and competitive inhibitor with a Ki value of 7.25±0.67 nM. Gemigliptin shows at least >23,000-fold selectivity for DPP-4 over various proteases and peptidases, including DPP-8, DPP-9, and fibroblast activation protein (FAP)-α[2].

Administration of gemigliptin supressed elevated serum levels of advanced glycation end products (AGE) in type 2 diabetic db/db mice. In mice and dogs, gemigliptin prevents the degradation of active glucagon-like peptide-1 by DPP-4 inhibition, which improves glucose tolerance by increasing insulin secretion and reducing glucagon secretion during an oral glucose tolerance test[2].
