Abstract

The present invention relates to the pharmaceutical field relevant to phlebothrombosis disease. Specifically, the present invention relates to a class containing the FXa inhibitor of two ring hydrazide structure, its preparation method and the application in preparation phlebothrombosis disease medicament.Wherein, R is selected from C1-C3Alkyl.

Description

One class contains coagulation factor xa inhibitors and the purposes thereof of bicyclic amide structure
Technical field
The present invention relates to the pharmaceutical field of phlebothrombosis disease treatment. More particularly, the present invention relates to the class that phlebothrombosis disease is had therapeutic action containing the FXa inhibitor of bicyclic amide structure, its preparation method, and the purposes in pharmacy.
Background technology
The deterioration of clotting ability is the important factor of unstable angina pectoris, brain osmanthus plug, cerebral embolism, cardiac muscle thrombosis when proposing the inaccessible again or extracorporeal circulation after the thrombosis after plug, lung infraction, pulmonary infarction, thromboangiitis obliterans, venous thrombosis, disseminated intravascular coagulation, replacing valve, revascularization. In Arterial system, abnormal thrombus is formed main relevant with coronary artery, the cerebrovascular and peripheral blood vessel, close that relevant disease mainly comprises that Acute Myocardial Infarction (AMI), instability stenocardia, thromboembolism and the thromboembolism treatment acute vascular relevant with percutaneous coronary artery angiography intracavity forming operation (PTCA) closes with the thrombosis of these blood vessels, transient ischemic attack, apoplexy, intermittent claudication and coronary artery bypass graft surgery (CABG) or peripheral arterial bypass graft. For vein blood vessel, pathologic thrombosis often occurs in the veins of lower extremity after belly, knee joint and Hip operation (venous thrombosis, DVT). DVT also makes patient be among the highly dangerous easily suffering from pulmonary thromboembolism. So, it is necessary to developing excellent anti-coagulant, this kind of anti-coagulant has excellent dose response, time length length, hemorrhage dangerous little, is almost free from side effects, and namely uses and oral also can reach abundant effect very soon.
Research according to the mechanism of action to various anti-coagulant, coagulation factor xa inhibitors (FXa inhibitor) is considered as good anti-coagulant. Factor Xa is second from the bottom kind of enzyme in blood coagulation chain. The restraining effect of factor Xa obtains by directly forming complex body between this inhibitor and enzyme, and therefore this enzyme is unrelated with blood plasma cofactor Antithrombin III. Effective factor Xa restraining effect is used this compound by oral administration, venoclysis continuously, quick dense note intravenously administrable or any other parenteral route approach and is realized, and thus can obtain the required effect stoping factor Xa to bring out thrombogen formation zymoplasm. Another advantage of FXa inhibitor be the effective dose in thrombotic model and in experimental hemorrhage model the dosage of time expand have very big difference. By this this test-results, it is possible to think that FXa inhibitor is the anti-coagulant that hemorrhage risk is less. Report the multiple compound being used as FXa inhibitor, and had and many ratify clinically, such as razaxaban etc.
The present invention discloses the FXa inhibitor containing two ring hydrazide structure of a class formation novelty, and these compounds can be used for preparing the medicine for the treatment of phlebothrombosis disease.
