Embodiment 1

[0021]

[0022] 2.43g (10mmol) compound II and 2.62g (10mmol) PPh 3 Dissolve in 20 mL of dry THF and reflux overnight under nitrogen protection. After the reaction mixture was cooled to room temperature, a white cloudy solution was obtained. Cooled to -78°C under nitrogen protection, slowly added 6.25mL (10mmol, 1.6M) n-BuLi n-hexane solution dropwise. After the dropwise addition was completed, stirring was continued for one hour, and a solution prepared by dissolving compound 1.28g (10mmol) III in 2mL of THF was added dropwise. After the dropwise addition was complete, the reaction mixture was slowly warmed to room temperature and then refluxed for 1 hour. The reaction mixture was poured into ice water, stirred, extracted with 50 mL×3 dichloromethane, the combined extracts were washed with brine, and dried over anhydrous sodium sulfate. The desiccant was removed by suction filtration, 0.50 g of iodine was added to the filtrate, and stirred overnight at room temperature....

Embodiment 7

[0033] Example 7 In vitro platelet aggregation inhibition test

[0034]Pharmacological tests of substances were performed in TRAP (thrombin receptor activating peptide)-induced platelet aggregation in 96-well plates. A 3.13% sodium citrate solution was pre-added into the syringe, and then 20 mL of blood from healthy volunteers was drawn in, centrifuged at 1500 g for 20 minutes, and the platelet-rich plasma (PRP) was separated and mixed with 1 μL of PGE1 solution (500 μg / mL ethanol solution) / mL PRP for treatment. After incubation at room temperature for 5 minutes, they were centrifuged at 1200 g for 20 minutes to remove leukocytes. Transfer the leukocyte-free PRP to 15 mL PP tubes in batches at 5 mL / portion, and centrifuge at 3600 g to pellet the platelets. Then, decant the upper plasma layer and resuspend the platelet pellet from 5 mL of PRP in 1 mL of Tyrode (120 mM NaCl, 2.6 mM KCl, 12 mM NaHCO 3 , 0.39mM NaH 2 PO 4 , 10 mM HEPES, 0.35% BSA, 5.5 mM glucose, pH=7.4), and...

Abstract

The invention relates to the field of medicine related to thrombotic diseases, in particular to a PAR-1 antagonist shown in the specification and containing a nitrobenzene and diene adamantine structure and a preparation method and application of the PAR-1 antagonist.

Description

Technical field [0001] The present invention relates to the field of medicine related to thrombotic diseases. Specifically, the present invention relates to a PAR-1 antagonist containing nitrobenzene and diene adamantane structures that has a therapeutic effect on thrombotic diseases and its preparation method, pharmaceutical compositions containing them and their use in the treatment of thrombotic diseases. purpose on. Background technique [0002] Protease Activated Acceptor-1 (PAR-1) is a recently discovered new target of antiplatelet and antithrombotic drugs. Protease-activated receptor 1 is also called thrombin receptor. Thrombin is activated by the coagulation chain and acts on platelets through the PAR-1 receptor to activate platelets, causing platelet aggregation and thus thrombosis and coagulation. Thrombus caused by PAR-1 is rich in platelet components and is the main cause of arterial thrombosis. PAR-1 antagonists can block thrombin from activating platelets, t...
