Definitions
- This invention relates to compounds useful for the treatment of thrombotic disorders, and more particularly to novel heterocyclic inhibitors of the enzyme thrombin.
- Plasma proteins such as fibrinogen, proteases and cellular receptors participating in hemostasis have emerged as important factors that play a role in acute and chronic coronary disease as well as cerebral artery disease by contributing to the formation of thrombus or blood clots that effectively diminish normal blood flow and supply.
- Vascular aberrations stemming from primary pathologic states such as hypertension, rupture of
- Thrombin is a key regulatory enzyme in the coagulation cascade. It serves a pluralistic role as both a positive and negative feedback regulator. However, in pathologic conditions the former is amplified through catalytic activation of cofactors required for thrombin generation as well as activation of factor XIII necessary for fibrin cross-linking and stabilization.
- thrombin In addition to its direct effect on hemostasis, thrombin exerts direct effects on diverse cell types that support and amplify pathogenesis of arterial thrombus disease.
- the enzyme is the strongest activator of platelets causing them to aggregate and release substances (e.g. ADP TXA 2 NE) that further propagate the thrombotic cycle.
- Platelets in a fibrin mesh comprise the principal framework of a white thrombus.
- Thrombin also exerts direct effects on
- thrombin activity constitutes a viable therapeutic approach towards the attenuation of proliferative events associated with thrombosis.
- ATIII antithrombin III
- Heparin exerts clinical efficacy in venous thrombosis by enhancing ATIII/thrombin binding through catalysis. However, heparin also catalyzes inhibition of other proteases in the coagulation cascade and its
- Hirudin derived from the glandular secretions of the leech Hirudo medicinalis is one of the high molecular weight natural anticoagulant protein inhibitors of
- hirudin as a therapeutic agent is its weak antigenicity and lack of an effective method of neutralization, especially in view of its extremely tight binding characteristics toward thrombin.
- the exceedingly high affinity for thrombin is unique and is attributed to a simultaneous interaction with the catalytic site as well as a distal "anion binding exosite" on the enzyme.
- Thrombin activity can also be abrogated by hirudin-like molecules such as hirulog (Maraganore, J.M. et al.,
- Thrombin activity can also be inhibited by low molecular weight compounds that compete with fibrinogen for
- thrombin' s catalytic site thereby inhibiting proteolysis of that protein or other protein substrates such as the thrombin receptor.
- a common strategy for designing enzyme inhibitory compounds relies on mimicking the specificity inherent in the primary and secondary structure of the enzyme's natural substrate.
- Blomback et al. first designed a thrombin inhibitor that was modeled upon the partial sequence of the fibrinogen A ⁇ chain comprising its proteolytically susceptible region (Blomback, et al., J. Clin. Lab. Invest., 24, 59, 1969). This region of
- fibrinogen minimally includes the residues commencing with phenylalanine:
- aldehyde group is presumed to contribute strongly to inhibitory activity in view of its chemical reactivity toward thrombin's catalytic Ser 195 residue, generating a hemiacetal intermediate.
- Maraganore et al. disclose a series of thrombin inhibitors that incorporate the D-Phe-Pro- moiety and hypothesize that this preferred structure fits well within the groove adjacent to the active site of thrombin. Variations on these inhibitors are essentially linear or cyclic peptides built upon the D-Phe-Pro moiety.
- hydrophobic groups provide additional binding through favorable Van der Waals interactions within a contiguous hydrophobic cleft on the enzyme surface designated the P 3 -P, site.
