, 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 are described. Also described are methods for preparing the compounds of Formula L 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.
本发明涉及氨基胍和烷氧基胍化合物,包括以下式子的化合物:1其中X为O或NR9,R1-R4、R6-R9、R11、R12、Ra、Rb、Rc、Y、Z、n和m在说明书中给出,以及其水合物、溶剂合物或药学上可接受的盐,其抑制蛋白酶如凝血酶。还描述了制备式L化合物的方法。本发明的新化合物是蛋白酶的强力抑制剂,尤其是类胰蛋白酶,如胰蛋白酶、凝血酶、纤溶酶和Xa因子。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,或者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体内血小板丧失、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,其中包括本发明中的化合物和药学上可接受的载体。本发明化合物的其他用途是作为抗凝剂,嵌入或物理链接到用于血液收集、血液循环和血液储存的设备制造中使用的材料中,如导管、血液透析机、血液采集注射器和管道、血液输送管和支架等。
