Embodiment 1

[0027]

[0028] 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....

Abstract

The invention relates to the field of medicine relevant to thrombotic diseases, in particular to a PAR-1 antagonist containing an alcoxyl phenyl group and a diene adamantane structure and a preparation method and application of the PAR-1 antagonist. According to the general formula (please see the specification), R is selected from an alkyl group of H, an alkyl group of C1-C5 and an alkyl group of C3-C8.

Description

technical field [0001] The invention relates to the field of drugs related to thrombosis diseases. Specifically, the present invention relates to a class of PAR-1 antagonists containing alkoxyphenyl and diene adamantane structures that have a therapeutic effect on thrombotic diseases, their preparation methods, pharmaceutical compositions containing them, and therapeutic effects on thrombotic diseases. Disease use. Background technique [0002] Protease Activated Acceptor-1 (PAR-1) is a new target of anti-platelet antithrombotic drugs discovered recently. Protease-activated receptor 1 is also called thrombin receptor. After thrombin is activated by the coagulation chain, it acts on platelets through PAR-1 receptors to activate platelets, causing platelet aggregation and causing thrombus and coagulation. The thrombus induced by PAR-1 is rich in platelet components, which is the main cause of arterial thrombus. PAR-1 antagonists can block thrombin from activating platelets,...
