, Y, Z, n and m are set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof, that inhibit proteolytic enzymes such as thrombin. Also described are methods for preparing the compounds of Formula I. 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. 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.
本发明涉及氨基胍和烷氧基胍化合物,包括公式I的化合物:其中X为O或NH,L为—O—或—SO2—,R1-R4,R9-R19,Ra,Rb,Rc,Y,Z,n和m在规范中设置,以及其水合物,溶剂化物或药学上可接受的盐,可抑制蛋白酶酶如凝血酶。还描述了制备公式I化合物的方法。其中某些化合物通过直接选择性抑制凝血酶表现出抗血栓活性,或是用于形成具有抗血栓活性的化合物的中间体。本发明包括一种用于抑制哺乳动物中的血小板丢失、抑制血小板聚集、抑制纤维蛋白形成、抑制血栓形成和抑制栓塞形成的组合物。本发明化合物的其他用途是作为抗凝剂,嵌入或物理连接到用于血液采集、血液循环和血液储存的设备制造材料中。
