Embodiment 1

[0018] The preparation of embodiment 1 compound I of the present invention

[0019]

[0020] In a 100mL round-bottomed flask, add 1.84g (10mmol) compound II, 1.62g (10mmol) compound III and 20mL dry THF, the resulting mixture is stirred under ice-water bath cooling, after adding 2.48g (12mmol) DCC, continue to Stir overnight at room temperature. TLC showed the reaction was complete.

[0021] The reaction mixture was poured into ice water, stirred, extracted with 50mL×3 dichloromethane, combined and extracted organic phases were washed with saturated brine, dried over anhydrous sodium sulfate, and the solvent was evaporated on a rotary evaporator, and the obtained residue column Chromatographic purification afforded product I as a white solid, ESI-MS, m / z=330 ([M+H] + ).

Embodiment 2

[0022] The preparation of embodiment 2 comparative compound 1-2

[0023] In order to further compare the drug efficacy of this compound, the present invention records the following formula comparative compound I-2 (new compound, not yet disclosed) and its preparation method and pharmacological data:

[0024]

[0025]

[0026] Its preparation method is as follows:

[0027]

[0028] In a 100mL round bottom flask, add 1.84g (10mmol) compound II, 1.26g (10mmol) compound III-2 and 20mL dry THF, the resulting mixture was stirred under ice-water bath cooling, after adding 2.48g (12mmol) DCC, Stirring was continued overnight at room temperature. TLC showed the reaction was complete.

[0029] The reaction mixture was poured into ice water, stirred, extracted with 50mL×3 dichloromethane, combined and extracted organic phases were washed with saturated brine, dried over anhydrous sodium sulfate, and the solvent was evaporated on a rotary evaporator, and the obtained residue co...

Embodiment 3

[0030] Example 3 In vitro Platelet Aggregation Inhibition Test

[0031] Pharmacological tests of substances were performed in TRAP (thrombin receptor activating peptide)-induced platelet aggregation in 96-well plates. 3.13% sodium citrate solution was added to the syringe in advance, and then 20 mL of blood from healthy volunteers was drawn in, centrifuged at 1500 g for 20 minutes, 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 adj...

Abstract

The invention relates to the field of thrombotic disease related medicines. Specifically, the invention relates to a formula (I) (shown in specifications) structured 2-pyridyl trans-cyclohexane amide structure-containing PAR-1 antagonist and application of the antagonist in preparation of medicines for treating thrombotic diseases.

Description

technical field [0001] The invention relates to the field of drugs related to thrombosis diseases. Specifically, the present invention relates to a PAR-1 antagonist containing a 2-pyridyl trans-cyclohexane amide structure that has a therapeutic effect on thrombotic diseases, and its application in the preparation of drugs for treating thrombotic diseases. 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, thereby blocking arterial thrombosis, and can be used to trea...
