Edoxaban tosylate (DU-176b) is a selective, potent and orally active factor Xa (FXa) inhibitor with K_is of 0.561 nM and 2.98 nM for free FXa and prothrombinase, respectively. Edoxaban tosylate is an anticoagulant agent and can be used for stroke prevention. Edoxaban tosylate is a also weak inhibitor of thrombin and factor IXaβ (FIXa), with K_is of 6.00 μM and 41.7 μM, respectively, exhibits >10 000-fold selectivity for FXa. Edoxaban tosylate has antithrombotic properties and has potential for thromboembolic diseases treatment^[1][2][3].

Ki: 0.561 nM (Free FXa); 2.98 nM (Prothrombinase); 6.00 μM (Thrombin) and 41.7 μM (Factor IXaβ)^[1]

Edoxaban (DU-176b) also inhibits rat, cynomolgus monkey and rabbit FXa with K_i values of 6.90 nM, 0.715 nM and 0.457 nM, respectively^[1].
Prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of human plasma are prolonged by Edoxaban (DU-176b) in a concentration-dependent manner, doubling PT and APTT at 0.256 and 0.508 μM, respectively. The double clotting time (CT2) for TT, however, was much higher (4.95 μM), reflecting its anti-thrombin activity. Thrombin-induced platelet aggregation is inhibited by a high concentration of Edoxaban (DU-176b) (IC₅₀: 2.90 μM), reflecting its weak anti-thrombin activity^[1].
Edoxaban is minimally metabolized (,4%) by the cytochrome P450 system (CYP3A4) and is a substrate for P-glycoprotein^[2].
