生物活性

描述
Betrixaban is a new, long-acting, oral and selectiveFactor Xainhibitor that decreases prothrombinase activity and thrombin generation.

IC50& Target

Factor Xa (Cell-free assay):1.5 nM

体外

In patch clamp hERG assays, Betrixaban has IC50of 8.9 μM. The plasma kallikrein IC50and Kivalues for Betrixaban are 6.3 μM and 3.5 μM respectively. Betrixaban (hERG Ki1.8 μM) exhibits significantly lower hERG activity than all the others (hERG Ki⩽0.5 μM).

体内

Dosed at 0.5 mg/kg IV and 2.5 mg/kg PO, Betrixaban has bioavailability of 51.6% in dog; dosed at 0.75 mg/kg IV and 7.5 mg/kg PO, Betrixaban has bioavailability of 58.7% in monkey. Both Betrixaban and Apixa-ban-mediated whole-blood INR increases are similarly reversed by r-Antidote. After i.v. infusion of the three fXa inhibitors (each admin¬istered individually) for 30 min, the total plasma concentrations of rivaroxaban, Betrixaban and apixaban are 1.4±0.4 μM (mean±s.d.), 0.2±0.01 μM and 1.4±0.3 μM, respectively, and the percentages of unbound inhibitor are 2.2%±0.8% (mean±s.d.), 40%±7.2% and 1.5%±0.3%, respectively. After administration of r-Antidote, the total plasma concentrations of the inhibitors increased to 1.9±0.09 μM, 2.0±0.4 μM and 4.2±0.7 μM, respectively, and the percentage of unbound inhibitor declined to 0%, 0.3%±0.1% and 0.05%±0.02%, respectively. Thus, for each of the three inhibitors, correction of prothrombin time by r-Antidote to near-normal values is associated with a reduction in the free fraction of the inhibitor.
