Gemigliptin (LC15-0444)

Gemigliptin (Zemiglo, LC15-0444) is a potent, selective and long-acting dipeptidyl peptidase 4 (DPP 4) inhibitor with a Ki of 7.25 nM. Gemigliptin shows at least >23,000-fold selectivity for DPP-4 over various proteases and peptidases, including DPP-8, DP

Background

[1] Sung-Ho Kim, et al. Eur J Pharmacol. 2016 Oct 5;788:54-64. [2] Sung-Ho Kim, et al. Arch Pharm Res. 2013 Oct;36(10):1185-8.

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/t, 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].
