30.0mg/ml Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.

生物活性

製品説明 Vildagliptin inhibits DPP−4 with IC50 of 2.3 nM.
in vitro

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. [1]
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. [1] 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. [2] 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. [3]

キナーゼアッセイ DPP-IV Inhibition Measurement
An extract from human colonic carcinoma cells (Caco-2) is used as the source of DPP-IV in the assay. The cells are differentiated to induce DPP-IV expression as described. Cell extract is prepared from cells solubilized in lysis buffer (10 mM Tris-HCl, 0.15 M NaCl, 0.04 T.I.U. (trypsin inhibitor unit) aprotinin, 0.5% nonidet-P40, pH 8.0) then centrifuged at 3.5×4g for 30 min at 4 °C to remove cell debris. The assay is conducted by adding 20 μg of solubilized Caco-2 protein, diluted to a final volume of 125 μL in assay buffer (25 mM Tris-HCl pH 7.4, 140 mM NaCl, 10 mM KCl, 1% bovine serum albumin) to 96-well flat-bottom microtiter plates. The reaction is initiated by adding 25 μL of 1 mM substrate. The reaction is run at room temperature for 10 min, and then 19 μL of 25% glacial acetic acid is added to stop the reaction. Fluorescence is measured using a CytoFluor II fluorometer (excitation 380 nm/ emission 460 nm). Vildagliptin and solvent controls are added as 30 μL additions, and the assay buffer volume is reduced to 95 μL.
