  • Patent number: 6635637
    Abstract: Cyclic oxyguanidine compounds, including compounds of Formulae I and II: wherein R1, R3-R6, R21-R26, L, Y, Z, and A are set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof, that inhibit proteolytic enzymes such as thrombin are described. Also described are methods for preparing the compounds of Formulae I and II. The novel compounds of the present invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as chymotrypsin, trypsin, thrombin, plasmin and factor Xa. Certain of the compounds exhibit antithrombotic activity via direct, selective inhibition of thrombin, or are intermediates useful for forming compounds having antithrombotic activity.

  • Patent number: 6476016
    Abstract: Cyclic oxyguanidine pyrazinone compounds are described, including compounds of the Formula I: wherein R3, R4, R5, W, and A are as set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof. The compounds of the invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as chymotrypsin, trypsin, thrombin, plasmin and factor Xa. Certain of the compounds exhibit antithrombotic activity via direct, selective inhibition of thrombin. Compositions for inhibiting loss of blood platelets, inhibiting formation of blood platelet aggregates, inhibiting formation of fibrin, inhibiting thrombus formation, and inhibiting embolus formation are described.
