Definitions
- the present invention relates to a novel compound having a platelet aggregation inhibitory effect and a salt thereof, and more particularly, a novel platelet aggregation inhibitor and an active ingredient which selectively inhibits shear stress-induced platelet aggregation by shear stress. It relates to a pharmaceutical composition and a method for producing the same.
- the human body has a self-healing or defense system to treat wounds and prevent blood loss, which is achieved by controlling and balancing platelet and plasma coagulation, fibrin breakdown, and coagulation inhibition.
- a variety of factors when appropriate control and balance is broken, abnormal platelet aggregation occurs and further develops into thrombotic disease.
- Thrombosis refers to the development of blood clots in the blood vessels, which can lead to disorders in the blood circulation or, in severe cases, blockage of blood flow.
- Thrombosis includes arterial thrombosis, phlebothrombosis, hepatic portal vein thrombosis, pulmonary thromboembolism, chronic limb ischemia, varicose vein (Varicose vein), deep vein It causes deep vein thrombosis diseases, angina pectoris, cerebral infarction, cerebral hemorrhage, and also causes infection or blood vessel damage, postoperative complications, and coagulation disease.
- thrombosis is produced by the interaction of abnormal blood vessel walls with hemodynamic forces, plasma coagulation proteins, and platelets.
- Platelets are activated by a variety of agents (adenosine diphosphate, thromboxane A 2 , thrombin, etc.), and activated glycoprotein IIb / IIIa of platelets can be found in the blood conjugate proteins (fibrinogen; fibrinogen, von Willebrand factor; von Willebrand factor, etc.). ), Causing aggregation reaction.
- shear stress is the most influential factor in the activation of platelets among physical stimuli, which means the force applied to blood vessels such as platelets, erythrocytes, and endothelial cells by blood flow.
- Abnormal changes in shear stress are the leading cause of pathological arterial thrombus in vivo, and percutaneous coronary interventions such as stents, thoracotomy, and balloon angioplasty. due to interventions such as arterial detachment, vascular spasm or hypertension, atherosclerosis, and the like.
- platelets When the shear stress rises abnormally, platelets are activated, and coagulation occurs by directly binding the bone protein urea and glycoprotein IIb / IIIa of activated platelets. This phenomenon accelerates the signaling system in platelets, increases intracellular calcium levels and releases various activators from granules, which in turn promotes platelet aggregation, producing thrombi (Nesbitt et al., Nature Medicine 15). , 665-673 (2009)
- thrombosis diseases include antiplatelet agents (eg, aspirin, clopidogrel, etc.), anticoagulants (eg, heparin, warfarin, etc.) that antagonize chemical agents, and thrombolytic agents to treat formed clots (eg, tissue plasminogen activator). Etc. are used.
- Aspirin is effective but is known to cause side effects such as gastrointestinal bleeding and peptic ulcers.
- most of the drugs used as anticoagulants cannot be orally administered, and have low selectivity for blood clots, and thus have various side effects such as bleeding, hemolysis, immune response, fever, and allergies when taken for a long time.
- the price of a commercially available therapeutic agent is very expensive, which makes it difficult for patients to use it easily.
- the present application is based on the finding that compounds obtained through the structure activity relationship of anti-platelet aggregation inhibition including amide and ester structure are useful for preventing or treating thrombotic diseases while having fewer side effects such as bleeding.
- the present application relates in one embodiment to a compound represented by formula (I) or (II) below, or a pharmaceutically acceptable salt or isomer thereof.
