Definitions
- the present invention relates to the field of medicinal chemistry and antithrombotic diseases, in particular to a 3-cyanopyridine compound, its enantiomers, diastereomers, racemates and mixtures thereof, and pharmaceuticals An acceptable salt or a pharmaceutical composition containing the above compound, a method for preparing the same, and use for preparing an anti-thrombotic drug.
- Thromboembolic diseases include acute coronary syndrome (ACS), stroke, deep vein thrombosis, pulmonary embolism, ischemic stroke, and myocardial infarction. According to statistics, about 12 million people worldwide die from thromboembolic diseases every year. Thrombotic diseases have occupied the first place in the global total mortality rate of diseases. Current treatment strategies include antiplatelet, anticoagulant, and thrombolytic, of which antiplatelet drugs account for about 70% of the market share of antithrombotic drugs.
- the rupture of atherosclerotic plaques or the implantation of artificial materials in the patient’s coronary arteries can cause platelet activation, and the activated platelets can release organisms such as hemoglobin A 2 (TXA 2 ) and adenosine diphosphate (ADP).
- ADP adenosine diphosphate
- glycoproteins (GPII b /III a ) on the surface of platelet membranes bind to fibrinogen, so that adjacent platelets adhere to each other to form a thrombus.
- ADP is an important platelet agonist in vivo, which mainly exerts its physiological activity by binding to two G-protein coupled receptors P2Y 1 and P2Y 12 on the surface of platelets.
- P2Y 1 receptor participates in platelet deformation and is widely distributed, while P2Y 12 receptor plays an important role in enhancing the release of platelet particles, the production of thromboxane A2, maintaining GPII b /IIIa activation and stabilizing platelet aggregation, and is mainly distributed in platelets On the membrane, therefore, P2Y 12 receptor antagonists are the most important area for the development of anti-platelet aggregation drugs (Thrombosis Research, 2014 (134), 693–703).
- the clinically used P2Y 12 antagonists include clopidogrel, prasugrel, ticagrelor and cangrelor.
- Clopidogrel is an irreversible oral prodrug of P2Y 12 antagonists and requires the metabolic activation of CYP450 to function.
- Clopidogrel and aspirin combination therapy has become the standard antiplatelet therapy.
- Prasugrel is a third-generation irreversible P2Y 12 antagonist and does not require CYP450 enzyme metabolic activation, so it has a faster onset of action.
- prasugrel Compared with clopidogrel, prasugrel has higher anti-platelet activity and is more effective in different populations. The response difference is lower, but high activity brings its higher risk of bleeding (Thrombosis Research 134 (2014) 693–703).
- Clopidogrel and prasugrel are potent and irreversible inhibitors of platelets. Platelets can recover function about seven days after drug withdrawal (platelet regeneration cycle is about 7-14 days).
- Tigrelo developed by AstraZeneca, is the first reversible direct P2Y 12 receptor antagonist. It does not require metabolic activation to function. Its effectiveness is not affected by genetic polymorphisms, compared with clopidogrel The clinical effect is better.
- ticagrelor after clinical administration of ticagrelor, patients had a black frame warning of increased mortality caused by stroke, and side effects such as dyspnea and ventricular pause.
- the above side effects may be caused by ticagrelor having an ADP structure and inhibiting the off-target effect caused by the equilibrative nucleoside transporter 1 (ENT1).
- ENT1 equilibrative nucleoside transporter 1
- AZD1283 is a new generation of reversible non-nuclear glycoside P2Y 12 receptor antagonist developed by AstraZeneca. It has entered phase II clinical research, but because the ester structure in the molecular structure is easily hydrolyzed into an ineffective carboxyl group, it is in the human body. Absorption and metabolic properties are extremely poor, which in turn leads to insignificant efficacy and stops at Clinical II (Bioorg. Med. Chem. Lett. 26 (2016) 2739-2754).
- prasugrel and ticagrelor were marketed in 2009 and 2011, respectively, the two have been recommended for first-line treatment of ACS, and clopidogrel (formerly the first-line treatment drug) is only recommended for the first two intolerance Of ACS patients.
- the prasugrel and ticagrelor treatment guidelines stipulate a course of treatment of at least 12 months, but in clinical practice, these powerful antiplatelet drugs have long-term treatment because of side effects, especially the higher risk of bleeding compared to clopidogrel It's very difficult.
- Highly activated platelets will be completely replaced by new platelets within 1-2 weeks after the onset of ACS. Patients with high levels of platelet antagonism may be necessary only a few days or weeks after the acute attack of ACS. After the condition stabilizes, treatment needs The conversion from high-level platelet inhibitors (prasugrel, ticagrelor) to medium-strength, safer inhibitors helps to reduce the risk of bleeding from long-term antiplatelet therapy. Therefore, finding an oral, safe, effective, and reversible P2Y 12 receptor antagonist is still an urgent clinical need and has important significance.
- the inventors designed and synthesized a series of compounds using AZD1283 as the lead compound, conducted a systematic structure-activity relationship study, and structured all new compounds Confirm and evaluate their in vitro anti-platelet aggregation activity, pharmacokinetic properties, CYP (cytochrome) enzyme inhibitory activity, in vivo anti-thrombotic activity, a new class of 3-cyanopyridine compounds were discovered for the first time Platelet activity, in vivo antithrombotic activity and metabolic properties are significantly better than AZD1283, and safety is better than clopidogrel.
- the new compound of the invention overcomes all the defects of AZD-1238, has better medicine forming property, and is suitable as a novel oral antiplatelet drug for the treatment of thrombotic diseases. On this basis, the inventor completed the present invention.
