Ordering Information

Biological Activity

Asundexian is an orally active coagulation factor XIa (FXIa) inhibitor that directly targets human FXIa with an ICof 1 nM. By reversibly binding to the active site of FXIa, it blocks enzymatic function within the intrinsic coagulation pathway. This inhibition attenuates contact-activation-triggered thrombin generation, prolongs activated partial thromboplastin time, and reduces vascular thrombus formation. [1]
