Catalog No.S3031 Synonyms: BI-1356
CAS No. 668270-12-0
Linagliptin (BI-1356) 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. Linagliptin activates glomerular autophagy in a model of type 2 diabetes. DPP4 mediates ferroptosis in TP53-deficient CRC cells.

Effect of linagliptin on oxidative stress in rat hearts suffered from 9 h of hypothermic preservation followed by 60 min of reperfusion. (A) Representative image of NOX2 detected by western blotting. (B). Densitometric analysis showing the expression of NOX2 using β‑actin for normalization. Data are mean ± S.E.M. (n = 3) and expressed as fold increase relative to the value of control group. (C-E) Measurement of MnSOD activity, ROS and MDA content. Data are expressed as mean ± S.E.M., n = 8. *P < 0.05, **P < 0.01 vs control group; #P < 0.05, ##P < 0.01 vs Celsior group. NOX2: NADPH oxidase 2; MnSOD: manganese superoxide dismutase; ROS: reactive oxygen species; MDA: malondialdehyde.

Linagliptin shows a potent inhibition effect against DPP-4 in vitro and a low affinity for hERG channel and M1 receptor (IC50 295 nM).  Linagliptin acts as a competitive inhibitor with a Ki 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. 
In male Wistar rats, Beagle dogs, and Rhesus monkeys, Linagliptin shows a highly efficacious, long-lasting, and potent inhibitory activity against DPP-4 by more than 70% inhibition for all three species after oral administration of 1 mg/kg. Oral administration of Linagliptin to db/db mice 45 min before an oral glucose tolerance test reduces plasma glucose excursion in a dose-dependent manner from 0.1 mg/kg (15% inhibition) to 1 mg/kg (66% inhibition).  By inhibiting DPP-4 activity, Linagliptin 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. 
|In vitro||DMSO||17 mg/mL (35.97 mM)|
|Ethanol||1 mg/mL (2.11 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
0.5% hydroxyethyl cellulose
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
