|Description||Vildagliptin (LAF-237) inhibits DPP−4 with IC50 of 2.3 nM.|
Vildagliptin is the most stable DPP-IV inhibitor, binding in the S1- and S2-catalytic sites of DPP-IV, possessing a P-1 site transition-state mimetic. 
|In vivo||Vildagliptin(orally dosed with 10 μmol/kg) is a potent, orally active inhibitor of plasma DPP-IV activity that provides increased levels of GLP-1 in an oral glucose tolerance test (OGTT) with Obese male Zucker rats. Vildagliptin orally dosed with 10 μmol/kg both significantly decreases glucose excursions and stimulates insulin secretion in Obese male Zucker rats. Maximum inhibition of plasma DPP-IV activity (95%) is observed approximately 2 hours postdose of Vildagliptin (1 μmol/kg, po) while >50% inhibition of DPP-IV is observed within 30 min postdose and persisted for >10 hours in normal Cynomolgus monkeys.  Vildagliptin(60 mg/kg) increases pancreatic beta cell mass through enhanced beta cell replication and reduced apoptosis, and the increased beta cell mass is sustained for 12 days after vildagliptin washout.  Vildagliptin administrated at doses of 10 mg/kg for 32 weeks protects nerve fiber loss in streptozotocin (STZ)-induced diabetic adult male Sprague Dawley rats. |

|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
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.

1.Please make sure the liquid is clear before adding the next solvent.
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.
