Description

New Xibazin analogues, pharmaceutical compositions thereof and their use in medicine

The present invention relates to the field of organic chemistry and pharmacy, in particular, the present invention relates to a novel cebacin analog having the structure of formula (II) and the stereoisomers, tautomers of the compound of formula (II) A construct, prodrug or pharmaceutically acceptable salt or solvate and pharmaceutical composition containing the same, 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 of 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 not only platelets The initial reaction acts as a signal amplification and maintenance, and causes the platelets in the blood circulation to gradually form a thrombus. The initiation of multiple clotting 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 clotting and hemostasis. 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 initiated by proteolytic hydrolysis, so thrombin receptors are also known as Protease Activated Receptors (PARs). There are four PARs subtypes, widely distributed in tissues, PAR-1, PAR-3 and PAR-4 can be activated by thrombin, and 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 initiation. Murine platelets express both PAR-1 and PAR-3 receptors.

Oral antithrombotic drugs that are currently on the market act by 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 inevitably leads to 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 initiation without affecting thrombin-mediated fibrinogen cleavage, while PAR-1 receptor inhibitors also do not affect platelet adhesion, initiation or aggregation pathways Related factors such as collagen, vWF and 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. In addition, thrombin receptor antagonists can 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.

Since the discovery of thrombin receptors, many pharmaceutical companies have been working on new drug development studies targeting thrombin receptors. A series of patent applications for thrombin receptor antagonists have been disclosed, such as WO03089428, which discloses a class of bisulphonin derivatives; and WO2002085855 discloses a 2-iminopyrrolidine derivative. In the phase III clinical trial, 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. 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.

Biological Test Example 1: Calcium ion transport inhibition assay

The model described below indicates that the compound of the present invention is a PAR-1 receptor inhibitor. In various cell types, activation of the PAR-1 receptor by a selective PAR-1 agonist triggers an intracellular signaling pathway that causes the endoplasmic reticulum to release calcium ions. In the KNRK cell line expressing human PAR1, calcium release from the receptor initiated by SFLLR was measured by fluorescence technique using a calcium ion selective probe. The emission intensity of the fluorescence is directly proportional to the activity and concentration of the PAR-1 antagonist. This method can determine the effect of the compounds of the invention on PAR-1 mediated calcium ion transport.

6. Inhibitor activity in the experimental results is expressed as the percentage of the fluorescence intensity of the inhibitor at different concentrations as a percentage of the blank control haTRAP excitation fluorescence intensity.
