Betrixaban Usage And Synthesis

Uses

Betrixaban is a novel anticoagulant, an oral direct inhibitor of factor Xa (FXa) for use in the prevention of venous thromboembolism (VTE).

Definition

ChEBI: Betrixaban is a secondary carboxamide obtained by formal condensation of the carboxy group of 4-(N,N-dimethylcarbamimidoyl)benzoic acid with the amino group of 2-amino-N-(5-chloropyridin-2-yl)-5-methoxybenzamide. A synthetic anticoagulant compound that targets activated factor Xa in the coagulation cascade. It has a role as an anticoagulant and an EC 3.4.21.6 (coagulation factor Xa) inhibitor. It is a member of guanidines, a member of benzamides, a secondary carboxamide, a monochloropyridine and a monomethoxybenzene.

Biological Activity

betrixaban is a highly potent, selective, and orally efficacious inhibitor of factor xa with ic50 value of 1.5nm [1].betrixaban shows excellent anticoagulant potency in vitro. in the rabbit deep vein thrombosis model, the concentration of betrixaban required to double the rabbit prothrombin time is below 2μm. betrixaban is selective for fxa and has poor activity for thrombin, trypsin, t-pa and apc. the patch clamp herg assay shows that betrixaban has low affinity with herg suggesting it is safer than other candidate compounds. in addition, betrixaban displays a profile of good oral bioavailability and oral exposure, long half-life in animal models. it has bioavailability of 51.6% at dose of 0.5 mg/kg iv and 2.5 mg/kg po. furthermore, the phase ii study has proved betrixaban as an oral fxa inhibitor for prevention of venous thromboembolic events [1].
