Abstract
Description
[Technical field]
[0001] The present invention relates to the field of medicine, specifically to polysubstituted uracil derivatives, and their preparation methods and applications. [Background technology]
[0002] Thrombosis can occur at any age and at any time, and has a high disability and mortality rate, seriously threatening human life and health. According to statistics, about 18 million people die from various thrombotic diseases around the world every year, and deaths from thrombotic diseases account for 51% of the total number of deaths in the world, ranking first in the total mortality rate in the world. In China, there are 1.5 million new thrombosis patients every year, and 2.5 million people suffer from thrombotic diseases every year, of which 70% of patients suffer from sequelae.
[0003] Currently, drugs commonly used in the prevention and treatment of thrombosis can achieve the purpose of inhibiting or reversing the formation of thrombus by intervening in various stages of the blood coagulation process (e.g., inhibiting the activity of blood coagulation factors, inhibiting platelet aggregation, etc.). For a long time, antithrombotic drugs have made great progress in terms of efficacy, etc. However, all antithrombotic drugs in clinical practice, whether they are old drugs that have been used for decades or new antithrombotic drugs released in recent years, are accompanied by various degrees of side effects, among which the risk of bleeding is a common drawback of all kinds of antithrombotic drugs, and may even become a life-threatening malignant risk. This defect limits the clinical application of such drugs and seriously threatens the drug safety of patients. There is currently no satisfactory clinical solution to this defect. Currently, most drugs (e.g., clopidogrel) do not have specific rescue drugs, and when severe bleeding occurs, only platelet replacement, fresh blood coagulation factors, etc. can be used as first aid. Therefore, clinically, there is an increasing market demand for mild antithrombotic drugs, and they are expected to be widely applied to the prevention and treatment of heart, brain and other arterial circulatory disorders caused by high platelet aggregation, such as recently diagnosed cerebral stroke, myocardial infarction, and confirmed peripheral arterial disease.

[0056] The present invention provides a polysubstituted uracil derivative as shown in formula I, and its preparation method and application.

[0057] The series of target pharmaceutical compounds synthesized by the above reactions are all novel compounds, and their structures are as follows: 1 Characterized by H NMR and ESI-MS. Through animal model testing, the results strongly demonstrate that the polysubstituted uracil derivatives have a certain antiplatelet aggregation activity, and the activity is equivalent to or superior to the corresponding positive control clopidogrel.

Finally, 1 hour after administration, the blank group was given 0.1mL / 10g of saline, and the remaining groups were given 0.15mL / 10g of 0.3% ellagic acid solution by tail vein injection. After 5 minutes, blood was collected from the glass capillary through the retroorbital venous plexus, and blood was collected through the glass tube every 10 seconds, and the time when blood coagulation filaments appeared was recorded. The experimental results are shown in Table 1. Calculation formula for blood clotting time prolongation: Blood clotting time prolongation rate (%) = [(mean blood clotting time of blank group or administration group / mean blood clotting time of model group) - 1] x 100%

The animals in each group were administered 0.1ml / 10g body weight of drug solution by gavage (ig), and the blank control group was administered distilled water once a day for 4 consecutive days. On the 4th day, 1 hour after administration, the animals were anesthetized by intraperitoneal injection of sodium barbiturate at a dose of approximately 50mg / kg, and after 20 minutes, the tails of the mice were cut 3mm from the tip of the tail, and the blood of the cut tail was periodically collected with absorbent paper until no blood leaked out, and the bleeding time was recorded, and the experimental results are shown in Table 2.

Effects of prophylactic administration of compounds on cerebral ischemia-reperfusion injury in rats Experimental method: SD rats were randomly divided into 6 groups, including a sham operation group, a model control group, a positive control drug ozagrel (6 mg / kg) group, and groups receiving high (9 mg / kg), medium (3 mg / kg), and low (1 mg / kg) doses of the test compound 1-1. The treatment group was administered in advance by tail vein injection, and the sham operation group and model control group were administered an equal amount of saline once a day for three consecutive days. 10 minutes after the last administration, a rat MCAO / R model was established, and reperfusion was performed after 2 hours of ischemia. 24 hours after MCAO reperfusion, neurobehavioral scores were performed to measure the neurological function of the rats, and the cerebral infarction rate and brain water content of the rats were measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining method.
[0132] The results are as follows: [Table 3] As can be seen from Table 3, the cerebral infarction rate of rats in the model group reached 33.61±3.56%, indicating that the modeling was successful. Compared with the model group, the white infarction area of the surgical side of rats in each administration group was reduced to various degrees, where the positive drug ozagrel (6mg / kg) group and the test drug compound 1-1 high dose (9mg / kg) group can significantly reduce the cerebral infarction rate of rats with focal cerebral ischemia-reperfusion injury (P<0.01).
[0133] [Table 4] As can be seen from Table 4, compared with the sham operation group, the brain water content of rats with focal cerebral ischemia-reperfusion in the model group was significantly higher than that in the sham operation group, indicating that the modeling was successful; compared with the model group, the positive drug ozagrel (6 mg / kg) group and the test drug compound 1-1 high dose (9 mg / kg) group can significantly reduce the brain water content of rats with focal cerebral ischemia-reperfusion injury (P<0.01).
[0134] [Table 5] As can be seen from Table 5, after MCAO / R, the rats in the model group have higher neurobehavioral scores, which indicates that the rats in the model group have severe neurological dysfunction.Compared with the model group, the positive drug ozagrel (6mg / kg) group and the test compound 1-1 high dose (9mg / kg) group can significantly reduce the neurological function score of rats with focal cerebral ischemia-reperfusion injury (P<0.01).

Inhibitory effect of compounds on myocardial ischemia-reperfusion injury induced by coronary artery ligation in rats Experimental method: Establish a myocardial ischemia-reperfusion (MI / R) injury model by coronary artery ligation in rats, and group the animals into high dose (20mg / kg), medium dose (10mg / kg), low dose (5mg / kg), clopidogrel (7.5mg / kg), sham operation, and model groups. The sham operation and model groups are administered with equal amounts of 0.5% CMC-Na, with the dose being 0.5ml / 100g body weight. The rats are given by gavage (ig) once a day for 5 consecutive days. Modeling is performed 30 minutes after the last administration, and 8 rats that have been successfully modeled after modeling are selected from each group for the next experiment. The sham operation group is left without ligation of the left anterior descending coronary artery according to the model preparation method, and the other groups are modeled according to the model preparation method. The effects of the test drugs on the myocardial infarction rate of rats and the biochemical indicators in plasma, such as creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA), and superoxide dismutase (SOD), were detected, and cardiac TTC staining was performed to detect the effects of the test drugs on the myocardial infarction area in MI / R rats.
[0136] The results are as follows: [Table 6]
[0137] [Table 7]
[0138] [Table 8] Conclusion: Compound 1-1 can affect the plasma biochemical indicators of rats with myocardial ischemia-reperfusion injury induced by coronary artery ligation, improve the degree of myocardial lesions, and inhibit the myocardial infarction rate, where the overall effect of the high-dose compound 1-1 group is slightly better than that of the positive drug clopidogrel group.
[0139] Example 60. Effect of combined administration of compound and urokinase (iv) on autologous thrombus and thrombin-induced ischemic brain injury in rats Experimental method: Prepare SD rat cerebral ischemia injury model by injecting autologous thrombus and thrombin from external carotid artery to internal carotid artery to embolize cerebral artery in rats. According to behavioral score, randomly divide into 5 groups, including sham operation group (only external carotid artery is isolated), model control group (two groups are given equal amount of saline), urokinase (5000U / kg) group, compound 1-1 (22.5mg / kg) group, etc. Each group has 20 rats (10 rats are used for detecting cerebral infarction rate, and 10 rats are referred to pathological detection). After 2 hours of modeling, administer once slowly into tail vein (1mL every minute), and monitor the reduction of blood flow after 120 minutes of administration after thrombin injection. After 24 hours, perform neurobehavioral scores on the rats to measure the neurological functions of the rats, measure the cerebral infarction rate and cerebral water content of the rats by 2,3,5-triphenyltetrazolium chloride (TTC) staining method, and use hematoxylin-eosin (HE) staining method to observe the cerebral pathological damage of the administered rats 2 hours after cerebral ischemia.
[0140] [Table 9]
[0141] [Table 10]

[0143] [Table 12]
[0144] Experimental results: Intravenous administration of compound 1-1, urokinase and compound 1-1 + urokinase after cerebral ischemic injury model caused by autologous thrombosis and thrombin can significantly reduce the reduction rate of cerebral blood flow in the model rats, the cerebral infarction area and cerebral water content in rats, and improve pathological damage and behavioral changes, where compound 1-1 + urokinase has the most obvious improvement level on cerebral ischemic injury caused by autologous thrombosis and thrombin. Experimental conclusion: Compound 1-1(iv) and the combined administration of compound 1-1(iv) with urokinase can reduce the cerebral infarction rate, cerebral water content and pathological damage in rats with autologous thrombus and thrombin-induced ischemic brain injury, and improve the neuromotor function of rats, indicating an excellent anti-ischemic brain injury effect.
[0145] Example 61. Improvement of focal permanent cerebral ischemic damage by administration 3 hours after ischemia Experimental method: Using the internal carotid artery suture embolization method, a cerebral artery occlusion (MCAO) model in rats was created. Forty-eight clean grade male SD rats weighing 250-300g were randomly divided into six groups according to body weight and sex, with eight rats in each group, which were the high dose group of compound 1-1, the medium dose group of compound 1-1, the low dose group of compound 1-1, the positive control butyrolide soft capsule group 60mg / kg, the sham operation group, and the ischemia model control group (all administered with an equal amount of 0.5% CMC-Na). Administration began 3 hours after MCAO surgery, and was given orally once a day by force, with a dose of 0.5ml / 100g body weight, for 14 consecutive days. One hour after the last administration, the animals were scored for neurological dysfunction according to the Bederson method, and then the rats were killed by decapitation, the whole brains were removed and weighed, the sections were stained with ttc, and photographed to calculate the infarction rate and water content of the brain tissue.
[0146] 48 clean grade male SD rats weighing 250-300g (100 rats are actually needed because the molding rate is about 50%) were randomly divided into 6 groups according to body weight, with 8 rats in each group. The grouping, administration and operation methods were the same as before. One hour after the last administration, the rats were killed by decapitation, the whole brain was removed and fixed in 10% formaldehyde solution, and coronal sections of the brain were taken, dehydrated, embedded in paraffin, and after sectioning and HE staining, the histopathological changes were observed under a light microscope, and the degree of pathological damage was scored.
[0147] Test Results: [Table 13] Results: Compound 1-1 in the medium and high dose groups can obviously reduce the mortality rate of rats.
[0148] [Table 14] Results: The body weight of rats in the sham operation group increased steadily for 15 days, while the body weight of rats in the model group showed an overall decreasing trend within 15 days. All the treatment groups had different degrees of effect on the weight maintenance of rats, which indicates that the average body weight within the group was significantly higher than that of the model group after 15 days. Here, the weight gain of the high dose group of compound 1-1 was significantly superior to that of the other treatment groups.
[0149] [Table 15] Results: The treatment group can significantly reduce the neurological function score of rats after 15 days, which appears as mild hooking and limb asymmetry, some rats fully recover and the neurological function score is 0, but the neurological function score of the model group is significantly higher than that of the treatment group, and in severe cases, it can reach 3 points, which appears as unable to walk straight and walking in circles all the time.
[0150] Conclusion: Compound 1-1 has the effect of improving brain nerve function. Furthermore, TTC staining revealed that the infarction rate and water content of the medium and high dose groups of Compound 1-1 were significantly reduced compared with the model group. Pathological examination showed that compared with the normal control group, the brain tissue of the model group showed obvious neuronal degeneration, necrosis, microglial proliferation, neuronal and interstitial edema, interstitial congestion, hemorrhage and other pathological changes. Compared with the model group, the pathological changes of each test group were alleviated, where the high dose group was most obviously reduced, and the pathological changes of the positive control group, especially the degeneration and necrosis of cortical neurons, were aggravated. This indicates that the test product has a certain improving effect on the pathological damage of permanent cerebral ischemia.
