Omarigliptin (MK-3102) is a competitive, reversible inhibitor of DPP-4 (IC50 = 1.6 nM, Ki = 0.8 nM). It is highly selective over all proteases tested (IC50 > 67 μM), including QPP, FAP, PEP, DPP8, and DPP9 and has weak ion channel activity (IC50 > 30 μM at IKr, Caγ1.2, and Naγ1.5).

|Description||Omarigliptin (MK-3102) is a competitive, reversible inhibitor of DPP-4 (IC50 = 1.6 nM, Ki = 0.8 nM). It is highly selective over all proteases tested (IC50 > 67 μM), including QPP, FAP, PEP, DPP8, and DPP9 and has weak ion channel activity (IC50 > 30 μM at IKr, Caγ1.2, and Naγ1.5).|
Omarigliptin is a potent inhibitor of DPP-4 and is highly selective over other proteases tested (IC50 > 67 μmol/L) and has weak ion channel activity (IC50 > 30 μmol/L at IKr, Caγ1.2, and Naγ1.5). Additionally, an IC50 > 10 μmol/L was obtained in all assays in an expansive selectivity counterscreen (168 radioligand binding or enzymatic assays). Omarigliptin binds rapidly and competitively to the active site of DPP-4, a process that is reversible and highly selective, and thus leads to increased levels of insulin and decreased levels of glucagon under hyperglycaemic conditions.
|In vivo||In lean mice, when orally administered 1 h prior to dextrose challenge in an oral glucose tolerance test (OGTT), it significantly reduced blood glucose excursion in a dose-dependent manner from 0.01 mg/kg (7% reduction in glucose AUC) to 0.3 mg/kg (51% reduction). the administration of omarigliptin dose-dependently increases plasma concentrations of active GLP-1. The pharmacokinetics of omarigliptin in male Sprague−Dawley rat and beagle dog are characterized by a low plasma clearance (0.9−1.1 mL/min/kg), a volume of distribution at steady state of 0.8−1.3 L/kg, and a long terminal half-life (∼11−22 h). The oral bioavailability of omarigliptin is good in both dogs and rats (∼100%). Omarigliptin is well-tolerated over the duration of the study, with no mortality or physical signs noted. Following the administration of a single oral dose of 25 mg in volunteers, omarigliptin was rapidly absorbed, with peak concentrations (Cmax) of 750 nmol/L reached within 1 h (Tmax). Bioavailability was estimated to be ≥74 %.|

* 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.
