Cat.No.S3031

Linagliptin (GSK2118436) is a highly potent, selective DPP-4 inhibitor with IC50 of 1 nM and exhibits a 10,000-fold higher selectivity for DPP-4 than for other dipeptidyl peptidases such as DPP-2, DPP-8, and DPP-9. This compound activates glomerular autophagy in a model of type 2 diabetes and mediates ferroptosis in TP53-deficient CRC cells via DPP4.

Mechanism of Action

Targets/IC₅₀/Ki	Ferroptosis ^[4] DPP-4 ^[1] (cell-free assay) 1 nM
In vitro	Linagliptin (GSK2118436) shows a potent inhibition effect against DPP-4 in vitro and a low affinity for hERG channel and M1 receptor (IC50 295 nM). ^[1] It acts as a competitive inhibitor with a K_i of 1 nM, and also shows 10,000-fold more selectivity for DPP-4 than DPP-8, DPP-9, amino-peptidases N and P, prolyloligopeptidase, trypsin, plasmin, and thrombin, and 90-fold more selectivity than fibroblast activation protein in vitro. ^[2]
In vivo	Linagliptin (GSK2118436) shows a highly efficacious, long-lasting, and potent inhibitory activity against DPP-4 in male Wistar rats, Beagle dogs, and Rhesus monkeys, with more than 70% inhibition for all three species after oral administration of 1 mg/kg. When administered orally to db/db mice 45 min before an oral glucose tolerance test, it reduces plasma glucose excursion in a dose-dependent manner from 0.1 mg/kg (15% inhibition) to 1 mg/kg (66% inhibition). ^[1] By inhibiting DPP-4 activity, this compound reduces the expression of the proinflammatory markers cyclooxygenase-2 and macrophage inflammatory protein-2, and enhances the formation of myofibroblasts in healing wounds from ob/ob mice. ^[3]
