Product Description

Biological Activity

Description Alogliptin is a potent, selective inhibitor of DPP-4 with IC50 of <10 nM, exhibits greater than 10,000-fold selectivity over DPP-8 and DPP-9. Phase 4.
Targets DPP-4
IC50 < 10 nM [1]
In vitro Alogliptin(SYR-322) is a potent inhibitor of DPP-4 and exhibits greater than 10,000 fold selectivity over the closely related serine proteases DPP-8 and DPP-9. Alogliptin is not an inhibitor of CYP-450 enzymes and does not block the hERG channel at concentrations up to 30 μM. [1]
In vivo Alogliptin(SYR-322) produces dose-dependent improvements in glucose tolerance and increases plasma insulin levels in female Wistar fatty rats. [1] Acute administration of alogliptin results in a significant decrease in plasma DPP-4 activity, and increases plasma active GLP-1. Alogliptin improves glucose tolerance at a dose of 0.3 mg/kg and higher, with a dose-dependent increase in plasma IRI, suggesting that improved glucose tolerance results from the ability of alogliptin to enhance insulin secretion.

Protocol(Only for Reference)

Kinase Assay: [1]

DPP-4 Assay Solutions of test compounds in varying concentrations (≤10 mM final concentration) are prepared in DMSO and then diluted into assay buffer comprising: 20 mM Tris, pH 7.4; 20 mM KCl and 0.1 mg/mL BSA. Human DPP-4 (0.1 nM final concentration) is added to the dilutions and pre-incubats for 10 minutes at ambient temperature before the reaction is initiated with A-P-7-amido-4-trifluoromethylcoumarin (AP-AFC; 10 μM final concentration). The total volume of the reaction mixture is 10-100 μL depending on assay formats used (384 or 96 well plates). The reaction is followed kinetically (excitation λ= 400 nm; emission λ= 505 nm) for 5 - 10 minutes or an end-point is measured after 10 minutes. Inhibition constants (IC50) are calculated from the enzyme progress curves using standard mathematical models.
