R wherein
1As above-mentioned definition;
Esterification process is: with formula (II) with through the amino acid (as: Boc amino acid, Fmoc amino acid) of overprotection amino, carry out the O-acylation, the preparation intermediate, again intermediate deprotection base is got formula I compound, or formula (II) and acyl chloride reaction prepared intermediate, again the hydrolysis of intermediate water can be got formula I compound, formula I compound is necessary to become acceptable addition salt on the medicine, comprises its subsalt or acid salt; Also can carry out esterification or acylation reaction with hydroxyl, amino, the carboxylic acid of the method for routine and formula I compound generates new derivative the present invention and comprises these derivatives.
Compound of the present invention is useful, because they have pharmacologically active in comprising human animal.Particularly this compound is useful aspect treatment or prevention vascular disease, be applicable to the apoplexy of outbreak in the recent period, myocardial infarction and the patient who makes a definite diagnosis peripheral arterial disease, the generation that can reduce artery congee ocean sclerosis incident is (as myocardium infarct, apoplexy and vascular death), with the acetylsalicylic acid associating, be used for non-ST section and raise impatient property coronary syndrome (unstable angina pectoris or non-Q wave myocardial infarction) patient; The example of the vascular disease that the present invention is contained comprises coronary occlusion, restenosis, acute coronary syndrome, high-risk vascular disease, cerebrovascular aneurysma, congestive heart failure, cardiac alternation, ventricular aneurysm, mural aneurysm, myocardial infarction, asystole, irregular pulse, cardiac edema, cardiac dyspnea, in heart failure, tachycardia, apoplexy, transient ischemic attack, cardiac hemoptysis, incompetence of cardiac valves, heart murmur, disposition is fainted, cardiac tamponade, cerebrovascular disease and/or peripheral arterial disease.
The compounds of this invention can the unit dosage form administration, and route of administration can be enteron aisle or non-enteron aisle, as oral, muscle, subcutaneous, nasal cavity etc.
The The compounds of this invention route of administration can be intravenously administrable.Injection comprises intravenous injection, intramuscular injection, subcutaneous injection and acupoint injection therapy etc.
Form of administration can be pharmaceutically acceptable preparations such as tablet, capsule, dispersible tablet, oral liquid, infusion solutions, little pin, freeze-dried powder.
The compounds of this invention is by the gross weight administration, and its amount is every kg body weight 0.01-40mg, and preferably the consumption of 24h is every kg body weight 0.1-20mg, also can adopt medication several times.
Preferred plan is that the amount that gives one or more active compounds of the present invention once a day is the 0.1-20mg/kg body weight, and preferred dose is the 0.1-5mg/kg body weight.In order to meet people or ideal occlusion regimen for animals, the difference of the visual state of an illness weight of this dosage, treatment difficulty or ease and compound used therefor fluctuates up and down, or follows the doctor's advice.
