Dabigatran (BIBR-1048) etexilate Thrombin inhibitor

Cat.No.S2154

Dabigatran Etexilate (BIBR-1048) is the prodrug of dabigatran, a potent, nonpeptidic small molecule that specifically and reversibly inhibits both free and clot-bound thrombin by binding to the active site of the thrombin molecule.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.

Mechanism of Action

Targets/IC50/Ki
Thrombin [1]
In vitro
Dabigatran selectively and reversibly inhibits human thrombin (Ki: 4.5 nM) as well as thrombin-induced platelet aggregation (IC50: 10 nM), while showing no inhibitory effect on other platelet-stimulating agents. Dabigatran selectively and reversibly inhibits human thrombin (Ki: 4.5 nM) as well as thrombin-induced platelet aggregation (IC50: 10 nM), while showing no inhibitory effect on other platelet-stimulating agents. Dabigatran inhibits thrombin generation in platelet-poor plasma (PPP) with IC50 of 0.56 μM, measured as the endogenous thrombin potential (ETP). Dabigatran demonstrates concentrationdependent anticoagulant effects in various species in vitro, doubling the activated partial thromboplastin time (aPTT), prothrombin time (PT) and ecarin clotting time (ECT) in human PPP at concentrations of 0.23, 0.83 and 0.18 μM, respectively. [1]
In vivo
Dabigatran prolongs the aPTT dose-dependently after intravenous administration in rats (0.3, 1 and 3 mg/kg) and rhesus monkeys (0.15, 0.3 and 0.6 mg/kg). [1] Dabigatran etexilate (20 mg/kg, orally) produces less prolongation of K value and less decreases in angle and maximum amplitude than enoxaparin in swine. [2] Dabigatran (0.01-0.1 mg/kg) reduces thrombus formation dose-dependently, with an ED50 (50% of the effective dose) of 0.033 mg/kg and complete inhibition at 0.1 mg/kg. Dabigatran etexilate (5-30 mg/kg) inhibits thrombus formation in a dose- and time-dependent manner, with maximum inhibition within 30 min of pretreatment, suggesting a rapid onset of action.[3]
