Definitions

  • the present invention relates to the field of organic chemistry and pharmacy, in particular, the present invention relates to a novel cebacin analog having a structure of formula (II), and stereoisomers of the compound of formula (II), Isomers, prodrugs or pharmaceutically acceptable salts or solvates and pharmaceutical compositions containing them, and uses thereof.
  • Cardiovascular and cerebrovascular events include acute coronary syndrome (ACS), myocardial infarction, cerebral thrombosis, etc., with high morbidity and high mortality.
  • the World Health Organization also pointed out that ischemic cardiovascular and cerebrovascular events are the leading cause of death. At present, more than 3 million people die from cardiovascular and cerebrovascular diseases every year in China, accounting for 40.3% of all deaths. The pathological cause of such diseases is due to the accumulation of thrombus after platelet activation, which leads to ischemia of the body tissues. Therefore, antithrombotic therapy is the main way to prevent cardiovascular and cerebrovascular events.
  • Platelet adhesion is the activation process of platelets, including the release of a variety of autocrine and paracrine factors, including adenosine diphosphate (ADP), thrombin, adrenaline, thromboxane A2, which are not only
  • ADP adenosine diphosphate
  • thrombin thrombin
  • adrenaline thromboxane A2
  • thromboxane A2 thrombin
  • the initial reaction of platelets acts as a signal amplification and maintenance, and causes platelets in the blood circulation to gradually form a thrombus.
  • Activation of various coagulation factors on the surface of platelets promotes the conversion of prothrombin to thrombin, which promotes platelet aggregation and promotes the conversion of fibrinogen to fibrin, which is the main cause of coagulation and hemostasis.
  • thrombin receptor The response of platelets to thrombin is mediated by platelet surface G-protein coupled receptors, the thrombin receptor. Further studies have found that thrombin receptors can be activated by proteolytic hydrolysis, so thrombin receptors are also known as Protease Activated Receptors (PARs).
  • PARs Protease Activated Receptors
  • PAR-1, PAR-3, PAR-4 can be activated by thrombin
  • PAR-2 is activated by trypsin or tryptase.
  • Human platelets express only two receptors, PAR-1 and PAR-4, of which PAR-1 plays a major role in thrombin-mediated platelet activation.
  • Murine platelets express both PAR-1 and PAR-3 receptors.
  • cyclooxygenase inhibitors that are currently on the market all play a role in inhibiting the platelet activation pathway.
  • the cyclooxygenase inhibitor aspirin inhibits the production of thromboxane A2.
  • Thiophene pyridines (such as clopidogrel) can irreversibly bind to the ADP receptor P2Y12 on the surface of platelets, thereby inhibiting platelet activation of ADP.
  • the platelet activation pathway induced by ADP and thromboxane A2 is a critical step for conventional pathological thrombosis and hemostasis. Therefore, the combination of cyclooxygenase inhibitors and thienopyridines is inevitable in exerting antithrombotic effects. The risk of bleeding complications increases. Therefore, although antiplatelet therapy has achieved good results in clinical practice, the risk of bleeding is still worthy of attention.
  • the PAR-1 mediated platelet activation pathway is primarily responsible for pathological thrombosis.
  • PAR-1 receptor inhibitors block thrombin-mediated platelet activation without affecting thrombin-mediated fibrinogen cleavage, while PAR-1 receptor inhibitors also do not affect platelet adhesion, activation, or aggregation pathways.
  • Related factors such as collagen, vWF, ADP and procoagulant (see Coughlin SR.; J Thromb Haemost., 2005, 3: 1800-1814), so PAR-1 receptor inhibitors have both antithrombotic effects and possible It does not increase the risk of bleeding and is an ideal antiplatelet drug.
  • thrombin receptor antagonists can also be combined with aspirin, clopidogrel, etc. to increase antithrombotic effects.
  • Thrombin receptor antagonists are also expected to be developed as new drugs against arteriosclerosis and cancer.
  • thrombin receptor antagonists have been disclosed, such as WO03089428, which discloses a class of bisulphonin derivatives; and WO2002085855 discloses a 2-iminopyrrolidine derivative.

  • the thrombin receptor antagonist SCH530348 developed by Merck showed that SCH530348 significantly reduced the incidence of cardiovascular diseases such as myocardial infarction or cerebral thrombosis, but also found adverse reactions to bleeding, especially stroke and transient.
  • thrombin receptor antagonists In patients with cerebral ischemia and cerebral hemorrhage, the risk of intracranial hemorrhage increases, which greatly reduces the current population of thrombin receptor antagonists. The development of new thrombin receptor antagonists with fewer bleeding side effects and better efficacy remains a major challenge.
