Definitions

  • This invention relates to novel heterocyclic compounds which are potent and highly selective inhibitors of factor Xa or factor Xa when assembled in the prothrombinase complex. These compounds show selectivity for factor Xa versus other proteases of the coagulation (e.g. thrombin, fVIIa, fIXa) or the fibrinolytic cascades (e.g. plasminogen activators, plasmin).
  • Blood coagulation protects mammalian species when the integrity of the blood vessel wall is damaged and uncontrolled loss of blood threatens survival. Coagulation, resulting in the clotting of blood is an important component of hemostasis. Under normal hemostatic circumstances, there is maintained an acute balance of clot formation and clot removal (fibrinolysis).
  • the blood coagulation cascade involves the conversion of a variety of inactive enzymes (zymogens) into active enzymes which ultimately convert the soluble plasma protein fibrinogen into an insoluble matrix of highly cross-linked fibrin.
  • thrombin A key enzyme in the coagulation cascade as well as in hemostasis, is thrombin.
  • Thrombin is intimately involved in the process of thrombus formation, but under normal circumstances can also play an anticoagulant role in hemostasis through its ability to convert protein C into activated protein C in a thrombomodulin-dependent manner.
  • Thrombin plays a central role in thrombosis through its ability to catalyze the penultimate conversion of fibrinogen into fibrin and through its potent platelet activation activity.
  • thrombin activity has been the focus of a variety of recent anticoagulant strategies as reviewed by Claeson "Synthetic Peptides and Peptidomimetics as Substrates and Inhibitors of Thrombin and Other Proteases in the Blood Coagulation System", Blood Coag. Fibrinol. 5:41 1-436 (1994).
  • the major classes of anticoagulants currently used in the clinic directly or indirectly affect thrombin (i.e. heparins, low-molecular weight heparins and coumarins).
  • thrombin i.e. heparins, low-molecular weight heparins and coumarins.
  • Thrombin is generated at the convergence of the intrinsic and extrinsic coagulation pathways by the prothrombinase complex.
  • the prothrombinase complex is formed when activated Factor X (factor Xa) and its non-enzymatic cofactor, factor Va assemble on phospholipid surfaces in a Ca +2 - dependent fashion as reviewed by Mann, et al, "Surface-Dependent Reactions of the Vitamin K-Dependent Enzymes", Blood 76:1-16 (1990).
  • Factor Xa Factor X
  • factor Va Factor Xa
  • the prothrombinase complex converts the zymogen prothrombin into the active procoagulant thrombin.
  • prothrombinase complex The location of the prothrombinase complex at the convergence of the intrinsic and extrinsic coagulation pathways, and the significant amplification of thrombin generation (393,000-fold over uncomplexed factor Xa) mediated by the complex at a limited number of targeted catalytic units present at vascular lesion sites, suggests that inhibition of thrombin generation is an ideal method to block uncontrolled procoagulant activity.
  • factor Xa appears to have a single physiologic substrate, namely prothrombin.
  • Plasma contains an endogenous inhibitor of both the factor Vila-tissue factor (TF) complex and factor Xa called tissue factor pathway inhibitor (TFPI).
  • TFPI is a Kunitz- type protease inhibitor with three tandem Kunitz domains.
  • TFPI inhibits the TF/fVIIa complex in a two-step mechanism which includes the initial interaction of the second Kunitz domain of TFPI with the active site of factor Xa, thereby inhibiting the proteolytic activity of factor Xa.
  • the second step involves the inhibition of the TF/fVIIa complex by formation of a quaternary complex TF/fVIIa/TFPI/fXa as described by Girard, et al, "Functional Significance of the Kunitz-type Inhibitory Domains of Lipoprotein-associated Coagulation Inhibitor", Nature 338:518-520 (1989).
