    • 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. The invention includes a composition for inhibiting loss of blood platelets, inhibiting formation of blood platelet aggregates, inhibiting formation of fibrin, inhibiting thrombus formation, and inhibiting embolus formation in a mammal, comprising a compound of the invention in a pharmaceutically acceptable carrier. Other uses of compounds of the invention are as anticoagulants either embedded in or physically linked to materials used in the manufacture of devices used in blood collection, blood circulation, and blood storage, such as catheters, blood dialysis machines, blood collection syringes and tubes, blood lines and stents.
    • 包括式I和II化合物的环状氧基胍化合物:其中R 1,R 3 -R 6,R 21 -R 26,L,Y,Z和A列于 描述了抑制蛋白水解酶如凝血酶的说明书以及其水合物,溶剂合物或其药学上可接受的盐。 还描述了制备式I和II化合物的方法。 本发明的新型化合物是蛋白酶,特别是胰蛋白酶样丝氨酸蛋白酶的有效抑制剂,例如胰凝乳蛋白酶,胰蛋白酶,凝血酶,纤溶酶和因子Xa。 某些化合物通过直接,选择性抑制凝血酶表现出抗血栓形成活性,或者是用于形成具有抗血栓形成活性的化合物的中间体。 本发明包括用于抑制血小板损失,抑制血小板聚集体形成,抑制纤维蛋白形成,抑制血栓形成和抑制哺乳动物栓塞形成的组合物,其包含本发明化合物在药学上可接受的载体中。 本发明化合物的其它用途是作为凝血剂或者物理上连接于用于血液收集,血液循环和血液储存(例如导管,血液透析机,采血注射器和管)中使用的装置的制造中使用的材料的抗凝剂, 血线和支架。
