, Z, and n 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 such compounds. 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. 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. Additionally, the compounds can be detectably labeled and employed for in vivo imaging of thrombi.
本文描述了氨基胍和烷氧基胍化合物,包括公式VII:其中X为O或NR9,Het,R1,R7,R8,R12-R15,Ra,Rb,Rc,Z和n在规范中列出,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。还描述了制备这种化合物的方法。本发明的化合物是蛋白酶的强效抑制剂,特别是胰蛋白酶样丝氨酸蛋白酶,如胰蛋白酶,凝血酶,纤溶酶和Xa因子。其中一些化合物通过直接、选择性地抑制凝血酶表现出抗血栓活性。本发明包括一种用于抑制哺乳动物中血小板丢失、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,其中包含本发明的化合物和药学上可接受的载体。本发明的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收集、血液循环和血液储存的器械制造中使用的材料中,例如导管、血液透析机、血液采集注射器和管、血液管路和支架。此外,这些化合物可以被检测标记并用于体内血栓的成像。
