Information
Omarigliptin (MK-3102) 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).
Targets
DPP-4 (Cell-free assay) 1.6 nM
In vitro
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 Glukagon 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 %.
