Information
Apixaban (BMS 562247-01) Apixaban (BMS 562247-01) is a highly selective, reversible inhibitor of Factor Xa with K i of 0.08 nM and 0.17 nM in human and rabbit, respectively.
In vitro
Apixaban exhibits a high degree of potency, selectivity, and efficacy on Factor Xa with Ki of 0.08 nM and 0.17 nM for Human Factor Xa and Rabbit Factor Xa, respectively. In vitro, Apixaban prolongs the clotting times of normal human plasma with the concentrations (EC2x) of 3.6 μM, 0.37 μM, 7.4 μM, and 0.4 μM, which are required respectively to double the prothrombin time (PT), modified prothrombin time (mPT), activated partial thromboplastin time (APTT) and HepTest. Besides, Apixaban shows the highest potency in human and rabbit plasma, but less potency in rat and dog plasma in both the PT and APTT assays.
In vivo
In the dog, Apixaban shows the excellent pharmacokinetics with very low clearance (Cl: 0.02 L kg-1 h-1), and low volume of distribution (Vdss: 0.2 L kg-1). Besides, Apixaban also exhibits a moderate half-life (T1/2: 5.8 hours) and good oral bioavailability (F: 58%). In the arteriovenous-shunt thrombosis (AVST), venous thrombosis (VT) and electrically mediated carotid arterial thrombosis (ECAT) rabbit models, Apixaban produces dose-dependent antithrombotic effects with EC50 of 270 nM, 110 nM and 70 nM, respectively. Apixaban significantly inhibits factor Xa activity with IC50 of 0.22 μM in rabbit ex vivo. In chimpanzee, Apixaban also shows small volume of distribution (Vdss: 0.17 L kg-1), low systemic clearance (Cl: 0.018 L kg-1 h-1), and good oral bioavailability (F: 59%).
