Ki: 0.19 nM (Factor Xa); 540 nM (Thrombin)
Razaxaban (compound 11d) shows good Caco-2 permeability.
The anticoagulant activity of Razaxaban (compound 11d) is evaluated in the in vitro human plasma activated partial thromboplastin time (aPTT) and human prothrombin time (PT) assays. Razaxaban shows a doubling of aPTT and PT at 6.1 μM and 2.1 μM, respectively. The human and rabbit plasma protein binding are found to be 90.5% and 93.4%, respectively, using equilibrium dialysis. Razaxaban is found to have similar affinity in the rabbit factor Xa assay with a K

of 0.16 nM.
Razaxaban (Compound 11d; 0.21-9.4 mg/kg/hour; intravenous injection) inhibits thrombus formation in a dose-dependent manner with an ID 50 of 1.6 μmol/kg/h in the rabbit arterio-venous shunt thrombosis model.
