Description

[0001] The present invention relates to a pharmaceutical composition and a functional food composition for preventing or treating thrombosis,

The present invention relates to a pharmaceutical composition or a health functional food composition for preventing or treating thrombosis comprising, as an active ingredient, a compound represented by the formula (1) or a pharmaceutically acceptable salt thereof,

Thrombus is a phenomenon that occurs due to inadequate occurrence of normal blood coagulation function, that is, the thrombus formation system mainly composed of fibrin is overcome the activity of thrombolytic system acting on fibrin removal. As a result, various types of diseases appear. Among them, stroke and cardiovascular diseases are the most common diseases. These are the three diseases that we often encounter with cancer. Cardiovascular disease is a disease that involves heart-related diseases (myocardial infarction, hypertension, heart failure, arrhythmia, arteriosclerosis) and vascular disease (stroke, peripheral vascular disease). According to statistics of the World Health Organization (WHO) Despite the remarkable progress, it has been reported that the incidence and prevalence increased steadily over the past 30 years, and it is a kind of fatal disease that accounts for a very high rate of mortality due to cardiovascular system diseases in Korea and worldwide, accounting for about 30% .

These cardiovascular diseases are most closely related to blood cholesterol, changes in blood components due to changes in lipid composition, and excessive mental tension, which are closely related to blood. Under normal conditions, the blood does not coagulate in the blood vessels, but when bleeding occurs, blood coagulation occurs as one of the body defense functions. However, when blood vessels are damaged due to changes in blood components, or if the blood flow is not smooth due to narrowing of the inner diameter of the blood vessels due to atherosclerosis, thrombus is formed to prevent the coronary artery or fine blood vessels supplying blood to the heart through the bloodstream Resulting in brain or cardiovascular disease. In addition, since the risk of recurrence is high in view of disease progression, lifelong treatment is often required.

Platelets, which play an important role in thrombus formation, are blood cells involved in hemostasis. They are made from bone marrow, have no nucleus, and have a disk shape with a radius of 3 ㎛ to 4 ㎛. When the blood vessels are damaged, the platelets adhere to the basement membrane and the collagen. At this time, platelets are said to be 'activated' and secrete substances that directly or indirectly induce platelet aggregation. Through this step, thrombin is produced with activation of endogenous coagulation cascade, thrombin converts fibrinogen to fibrin, and fibrin is stabilized by thrombin-activated coagulation factor. Under normal conditions, the thrombus produced by this fibrin is dissolved and restored to normal blood vessels, but in abnormal conditions, it causes thrombosis.

Thrombosis may be caused by atherothrombotic diseases, phlebothbombosis, hepatic protal vein thrombitis, pulmonary thromboembolism, chronic limbischemia, varicose vein, deep vein thrombosis deep vein thrombosis diseases, anginapectoris, cerebral infarction, cerebral hemorrhage, and also causes infection or vascular injury, postoperative complications, and coagulative diseases.

On the other hand, arteriosclerosis is a disease in which hypertrophy or tissue degeneration arises in the arterial wall and hardens (hardens). As the inner diameter of the artery becomes thicker and the inner diameter becomes narrower, the coronary artery supplying oxygen and various nutrients, , Which causes blood flow disorder, which is one of the major diseases associated with aging. Atherosclerosis is atherosclerosis, which is caused by fibrosis around the atheroma caused by excessive cell proliferation in the inner lining of the artery, and the vessel becomes harder. The term atherosclerosis is sometimes called arteriosclerosis.

Arteriosclerosis begins around the age of 10 years, and blood flow disorder occurs in the late 40s. In some cases, the fibrous membrane ruptures, resulting in blood clots in the blood vessels. Hemorrhage occurs in the atheroma and the blood vessel diameter rapidly narrows and causes various diseases. Atherosclerosis is apt to occur in the cerebral artery or coronary artery. In the case of cerebral artery sclerosis, it causes headache, dizziness, mental disorder and causes the cerebral palsy. In the case of coronary atherosclerosis, it causes pain and arrhythmia in the heart part and causes angina and myocardial infarction Is known to be. In addition, this causes heart disease, cerebral hemorrhage, and the like, and diseases caused by arteriosclerosis are becoming a major cause of death in modern society. In addition, arteriosclerosis is closely related to the development and progression of diseases such as obesity (overweight), thrombosis, hypercoagulability and thrombotic conditions (arterial and venous), metabolic syndrome such as obesity, Causes or aggravates chronic complications.

Arteries are divided into aorta, middle artery, and small artery, and are composed of three layers of intima, middle membrane and outer membrane. Especially, atherosclerosis is mainly developed in elasticity and muscular artery. Vascular smooth muscle cells that contract vasoconstriction and enlargement can migrate to the inner membrane after stimulation and have receptors for LDL. Under normal conditions, the proliferation is regulated by a very strict mechanism, but abnormally hyperplasia may cause vascular disease. In addition, vascular smooth muscle cells induce vascular restenosis in the treatment of ischemic heart disease represented by angina pectoris and myocardial infarction. In order to prevent this, anti-hypertrophy agents, Etc. have been administered, but they have not shown sufficient clinical effects.

Thrombosis therapy is classified into prevention of platelet aggregation, prevention of blood clotting, and dissolution of thrombus, and anticoagulation is the most effective method for prevention of double thrombosis.

Among the drugs that inhibit platelet coagulation function are non-steroidal anti-inflammatory drugs such as aspirin and indomethacin, which inhibit the metabolism of prostaglandin and reduce the generation of thromboxane or reduce the amount of cAMP in platelets . In particular, aspirin inhibits the synthesis of thromboxane A ₂ by irreversibly acetylating cyclooxygenase, which synthesizes prostaglandins, a platelet aggregation inducer, from arachidonic acid in cell membranes, Since there is no synthetic ability, the platelet aggregation inhibition effect is maintained until the platelets having a new enzyme appear, and the period of time is about 10 days.

However, nonsteroidal antiinflammatory drugs such as aspirin have excellent effects but have low selectivity and increase the risk of hemorrhage due to frequent gastrointestinal disorders, fatal side effects such as gastric perforation, agranulocytosis and aplastic anemia in the blood system, liver toxicity induction, There are disadvantages that cause side effects. To solve these problems, attempts have been made to develop medicines to interfere with gastric absorption, to administer medicines using injections, and to develop prodrugs that are metabolized and then activated in the liver. But did not have a significant effect on reducing the incidence of side effects.

Therefore, studies have been actively made to obtain platelet aggregation inhibiting components having excellent effects, which have no side effects as described above, from natural materials. Until now, antiplatelet clotting effect has been reported in natural products such as catechin, garlic, ginger, ginkgo extract, and ginseng of green tea. However, there is no antiplatelet clotting material showing good commercialization level. Therefore, it is necessary to study for the better detection of antiplatelet clotting material from natural products.

Under the circumstances described above, the present inventors studied a safe substance which is not harmful to the human body, which can be effectively used for prevention or treatment of thrombosis by inhibiting the platelet aggregation phenomenon. The compound represented by the formula (1) And exhibits an excellent inhibitory effect on platelet aggregation, thereby completing the present invention.
