Abstract
The invention relates to the field of pharmaceuticals for thrombotic diseases, in particular to a PAR-1 antagonist containing a diene tetrazolium and methoxyphenyl structure, a preparation method thereof and application thereof. According to the formula shown in the description, R1 is selected from H, alkyl of C1-C3 or cycloalkyl of C3-C5.
Description
Technical field
The present invention relates to the pharmaceutical field relevant to thrombus disease.Specifically, the present invention relates to the PAR-1 antagonist medicative class of thrombotic diseases being contained to diene tetrazole and methoxyphenyl structure and preparation method thereof, containing their pharmaceutical composition and the purposes on treatment thrombotic diseases.
Background technology
Proteinase activated receptors 1 (Protease Activated Acceptor-1, PAR-1) is the novel targets of the antiplatelet class antithrombotic reagent found recently.Proteinase activated receptors 1 is thrombin receptor again, zymoplasm by coagulation cascade activate after by PAR-1 receptor acting in thrombocyte thus activate thrombocyte, cause platelet aggregation thus cause thrombus and blood coagulation.Being rich in platelet component in the thrombus that PAR-1 causes, is the main reason of arterial thrombus.PAR-1 antagonist can block thrombin activation thrombocyte, thus interruption artery thrombosis, may be used for treatment acute coronary artery disease (Acute Coronary Syndrome).Several PAR-1 inhibitor has been had to be in clinical study (Chackalamannil S., Thrombin Receptor (Protease Activated Receptor-1) Antagonists as Potent Antithrombotic Agents with Strong Antiplatelet Effects, J.Med.Chem., 2006,49 (18), 5389-5403).
Traditional is divided three classes for the medicine preventing and treating thrombotic diseases.The first kind is anticoagulation class, be divided into direct thrombin inhibitor and indirect thrombin inhibitors, such medicine carrys out inhibition thrombosis by the different links acting on coagulation cascade, has and suppresses various thrombotic effect, as vitamin K antagon and Xa factor inhibitor etc.; Equations of The Second Kind is antiplatelet class, and as COX-1 inhibitor and adp receptor antagonist etc., such medicine is mainly used in preventing and treating arterial thrombus; 3rd class is fibrinolytic agent, is mainly used in the scleroproein formed in lysed blood.
Mostly antiplatelet drug is traditional arterial thrombus protective agents, as clopidogrel and acetylsalicylic acid etc.The shortcoming of these medicines is that bleeding risk is larger.And as the PAR-1 antagonist of newfound antiplatelet class antithrombotic reagent, then there is less bleeding risk, therefore this compounds can as the very promising medicine for the treatment of arterial thrombus.
The invention discloses the PAR-1 antagonist that a class contains diene tetrazole and methoxyphenyl structure, they may be used for the medicine preparing anti-arterial thrombus disease.
