Abstract
The invention relates to a substituted oxazolidinone compound and a preparation method and application thereof, and belongs to the field of medicinal chemistry. Particularly, the invention relates to the substituted oxazolidinone compound shown as a general formula I, wherein R1 expresses chlorine, bromine, methyl or trifluoromethyl; and R2 and R3 respectively express hydrogen or C1-10 alkyl. The compound or a medicinal salt thereof is used as a direct Xa factor inhibitor, used as an antithrombotic agent and used for treating cardiovascnlar and cerebrovascular diseases and thromboembolism disease.
Description
Technical field
The present invention relates to the pharmaceutical chemistry field, be specifically related to Qu Dai De oxazolidone compound, and their preparation method and as the purposes of pharmaceutical preparations having antithrombotic activity.
Background technology
Thrombus is meant blood ingredient in the blood flow process, at a kind of half grumeleuse shape material of blood vessel or the formation of cardiac intima surface.Thrombosis and cardiovascular disorder are closely related, are to threaten one of healthy important diseases of the elderly.According to position, reason, structure and the character of its formation, can it be divided into white thrombus, red thrombus and mixed thrombus etc.Impel thrombotic factor a lot, mainly contain the unusual and abnormal hemodynamics of blood vessel endothelium injury, inside and outside blood coagulation system etc.
Along with further illustrating of thrombosis mechanism, to thrombotic characteristics and reason, researched and developed a lot of antithrombotic new drugs, the medicine of existing inhibition thrombosis (anticoagulation) and anticoagulant has thrombolytic medicine again.The former mainly is to the formation of thrombus and increases inhibitedly that the latter is dissolved established thrombus, thereby eliminates the harm that thrombotic diseases causes the mankind.
(FXa inhibitor, FXaI), Xa factor is the thrombin that a kind of formation to zymoplasm has vital role to the Xa factor suppressor factor.The alternative Xa factor that suppresses of FXaI prolongs the clotting time, reduces zymoplasm and generates and reach anti thrombotic action.Interaction between FXaI and common drug and food is very little, need not to adjust dosage and medication monitoring.The Xa factor suppressor factor that acts on Xa factor can be divided into indirect Xa factor suppressor factor and direct Xa factor suppressor factor.
Along with the aging of population, the increase of cardiovascular disease incidence rate, estimate that the market structure of anticoagulant will change, warfarin and the heparin of monopolization over half a century will be substituted by direct thrombin inhibitors of a new generation and Xa factor suppressor factor gradually.
Summary of the invention
