Cơ Chế Tác Dụng :
ART-123 is a novel, recombinant and soluble thrombomodulin (ART-123). It is a human protein with both thrombin inhibiting and protein C stimulating activities, for the potential treatment of thromboembolism and blood clotting disorders, such as disseminated intravascular thromboembolism. (PMID: 12211414)
ART-123 is a soluble form of recombinant human thrombomodulin comprising all extracellular domains of thrombomodulin. Bound to thrombin, ART-123 inhibits its procoagulant activity and promotes activation of protein C. ART-123 inhibits thrombin generation by the activation of protein C and the subsequent inactivation of factor Va in the presence of protein S. ART-123 attenuates the extension of the clot by inhibiting further thrombin generation on clots, while other anticoagulants inhibit the initiation of clot formation. A higher concentration of ART-123 is needed to affect clotting time and platelet aggregation than thrombin generation.
