Abstract

The invention relates to the medicinal chemistry field, and discloses a nitric oxide donor with a thrombin inhibition effect, as well as a preparation method and medical application thereof, and particularly relates to a kind of pseudo-peptide antithrombase inhibitor (I), as well as a preparation method and an inhibition effect and an antithrombotic effect thereof on thrombin. Pharmacological experiment proves that the compound can be used for treating and preventing various diseases related to thrombosis, and the diseases comprise arterial thromboembolic diseases, venous thromboembolic diseases and other thrombotic cardiovascular diseases.

Description

One class has the inhibiting nitric oxide donors of zymoplasm, its method for making and medicinal use
Technical field
The present invention relates to pharmaceutical chemistry field, be specifically related to the non-peptide class of a class antithrombin inhibitor, they preparation method and to the restraining effect of zymoplasm and anti thrombotic action.
Technical background
Now, thrombotic cardiovascular and cerebrovascular diseases has become the formidable enemy who threatens human health, and arterial thromboembolism disease and venous thromboembolism disease are frequently-occurring diseases clinically.Since 1914 find heparin, anticoagulation medicine is being obtained considerable progress aspect prevention and treatment thrombus disease.Along with increasing and cardiovascular disorder multiple of world's elderly population, anticoagulation medicine will have vast potential for future development.
Dabigatran etcxilate (Dabigatran Etexilate) is developed by German Boehringer Ingelheim company, in April, 2008, in Germany and Britain, takes the lead in going on the market, and this is the first new classification oral anticoagulant thing going on the market over 50 years after warfarin.The listing of this product, is a major progress in anticoagulation therapy field and potential lethality thrombus prevention field, has milestone significance.Dabigatran etcxilate is a kind of novel, non-peptide class, competitiveness, reversible thrombin inhibitors, it is the prodrug of dabigatran (Dabigatran), orally after stomach and intestine absorb, be converted in vivo active part dabigatran, produce zymoplasm restraining effect.Dabigatran is incorporated into the scleroproein specific combination site of zymoplasm, stops Fibrinogen to be cracked into scleroproein, thereby has blocked final step and the thrombosis of blood coagulation waterfall network.Dabigatran can dissociate from scleroproein-zymoplasm combination, brings into play reversible anticoagulation.
