| Bioactivity |
Apixaban (BMS-562247-01) is a highly selective, reversible and orally active inhibitor of Factor Xa with Ki of 0.08 nM and 0.17 nM in human and rabbit, respectively[1]. Apixaban is in development for the prevention and treatment of various thromboembolic diseases[2]. |
| Target |
IC50: 0.08 nM (Human Factor Xa), 0.17 nM (Rabbit Factor Xa) |
| Invitro |
Apixaban (BMS-562247-01) 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[2]. |
| In Vivo |
Apixaban (BMS-562247-01) shows the excellent pharmacokinetics with very low clearance (Cl: 0.02 L/kg/h), and low volume of distribution (Vdss: 0.2 L/kg) in the dogs. Besides, Apixaban also exhibits a moderate half-life (T1/2: 5.8 hours) and good oral bioavailability (F: 58%)[1]. 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[2]. Apixaban significantly inhibits factor Xa activity with IC50 of 0.22 μM in rabbit ex vivo[3].In chimpanzee, Apixaban also shows small volume of distribution (Vdss: 0.17 L/kg), low systemic clearance (Cl: 0.018 L/kg/h), and good oral bioavailability (F: 59%)[4]. |
