Abstract

The present invention relates to the drug field related to angiocardiopathy.Specifically, P2Y12 receptor antagonists, its preparation method and its application in preparation treatment angiocardiopathy especially thrombotic disease medicine of the aryl oxidized phosphine structure of alcoxyl thiophene are contained the present invention relates to a class.Wherein, R is selected from H, C1‑C6Alkyl.

Description

One aryl oxidized phosphine P2Y12 receptor antagonists of class alcoxyl thiophene and application thereof
Technical field
The present invention relates to the drug field for the treatment of cardiovascular disease.In particular it relates to outstanding to angiocardiopathy It is the P2Y12 receptor antagonists that thrombotic disease has the aryl oxidized phosphine structure of medicative class thiophene containing alcoxyl Agent, Preparation Method And The Use.
Background technology
The medical complication relevant with there is thrombosis represents a kind of main cause of death.Some and development thrombus shape Include that acute myocardial infarction, unstable angina pectoris and chronic stable angina pectoris, transience lack into relevant pathology example Blood breaking-out, cerebrovas-cularaccident, peripheral vascular disease, pre-eclampsia and eclampsia, dvt formed, embolism (cerebral embolism, Pulmonary embolism, coronary embolism, renal embolism etc.), disseminated intravascular coagulation or thrombotic thrombocytopenic purpura.Invading Still there are the danger that thrombosis and ISR complication occur, the invasive surgical operation during and after entering property surgical operation Such as angioplasty, carotid endarterectomy, aortocoronary by-pass grafting or support or the peace of vascular endoprostheses Put.
Arterial thrombosis can occur after vascular damaged or atheromatous plaque rupture.Blood platelet is in these thrombus Necessary effect is played in formation.Blood platelet can be by following substance activating:In blood flow circulating cells or along vascular wall present The amboceptor that is discharged of damaging endothelial cell, or during injury of blood vessel exposed sub-endothelial matrix (such as collagen) blood Bolt forms molecule.Additionally, blood platelet can also be observed such as in narrow blood vessel under the blood flow conditions with shearing force As activate.After activation, the circulation platelet adhesion reaction is simultaneously accumulated at injury of blood vessel, forms thrombus.In this process, blood Produced thrombus is sufficiently large volume to blood flow in pipe, so that it is partially or completely blocked.
In vein, thrombus can also be located to be formed slowly in obstruction or blood flow.Due to the property of these phlebothrombosises, it can be produced The embolus moved in vascular system.These emboluses can thus block the blood flow in more remote blood vessel, the blood vessel such as lung Artery or coronary artery.
Verified 5'- adenosine diphosphate (ADP)s (ADP) are platelet activation and the principal mediator assembled for many researchs, in thrombus Played in the startup of formation and progress decisive role (Maffrand et al., Thromb.Haemostas., 1988,59, 225-230).ADP is discharged into circulation by the red blood cell and the endothelial cell of atherosclerosis wall for damaging, it is more specific and Speech, as secreted by the activation blood platelet with compacted grains in place of very high concentration storage ADP.The platelet aggregation of ADP- inductions The combination of two species specificity the purinergic receptor P2Y1 and P2Y12 by it and in the endoglin expression of human blood platelets is triggered.Institute P2Y1 acceptors are stated, combine with stimulating through the PLC β of G α q, be responsible for mobilization, the change of platelet shape and in ADP that internal calcium is stored On moment aggregation.The P2Y12, the activation of suppression and PI-3 kinases with the adenyl cyclase through G α i2 is combined, and is responsible for The amplification of response and the stabilisation of aggregation.P2Y1-/- transgenic mice (Gachet et al., J.Clin.Invest., 1999, 104,1731-1737) proved with using for P2Y12-/- mouse (Conley et al., Nature, 2001,409,202-207) Described two acceptors thrombus developing importance in vivo.In the mankind, P2Y12 gene defects and bleeding table are had been described above Type is relevant with the notable decline of the platelet aggregation that ADP- is induced.Human clinical put into practice in use clopidogrel it has been proved that The critical therapeutic strategy for the treatment of angiocardiopathy is represent by Antagonist block P2Y12 acceptors.Clopidogrel is thienopyridine The prodrug of family, its active metabolite is covalently bond to P2Y12 acceptors, and cause internal biologically active pdgf can not retroactive inhibition (Savi et al., Biochem.Biophys.Res.Commun., 2001,283,379-383), the medicine is in some clinical examinations Middle its efficiency of display is tested, that is, is reduced dangerous patient and cardiovascular unexpected danger is occurred.
The invention discloses the P2Y12 receptor antagonists of the aryl oxidized phosphine structure of a class thiophene containing alcoxyl, these compounds Can be used to prepare the medicine for the treatment of angiocardiopathy especially thrombotic disease.
