[0002] The present application relates to an aromatic compound, a preparation method and application thereof. BACKGROUND
[0003] ATP receptors are classified into two major families, P2Y- and P2X-purinergic receptors, based on molecular structure, transduction mechanism and pharmacological properties. P2X-purinergic receptors are a family of ATP-gated cation channels, several subtypes have been cloned, including: six homomeric receptors, P2X1; P2X2; P2X3; P2X4; P2X5; and P2X7; and three heteromeric receptors P2X2 / 3, P2X4 / 6, P2X1 / 5. P2X4 receptor is the only subtype of P2X family whose crystal structure has been solved, and its resolution is as high as And researches have found that P2X4 is the P2X subtype with the strongest permeability. 2+
[0004] Cough is the main symptom of respiratory diseases, and 70% to 80% of patients in the respiratory clinic have cough symptoms. With the increasing prevalence of COPD, IPF, and other diseases, the demand for cough as the main symptom of most expiratory tract diseases is also increasing. As a defensive reflex of the body, cough is beneficial to the removal of respiratory secretions and harmful factors, but frequent and severe cough can have a serious impact on the patient's work, life and social activities.
[0005] Currently, the indications of the drugs under research related to the P2X4 target are mostly neuropathic pain or inflammation, and there is no information on the research of drugs for cough indications. And there is no drug on the market for treating many diseases including chronic cough through P2X4 inhibition pathway. Therefore, the development of new compounds that can inhibit the activity of P2X4 has positive significance for the treatment of diseases. SUMMARY
[0006] The application provides an aromatic compound, a preparation method and application thereof. The compound has high P2X4 antagonistic activity, good safety and pharmacokinetic properties.
[0007] The application provides a compound as shown in Formula I, a pharmaceutically acceptable salt thereof, a stereoisomer thereof, a tautomer thereof, an isotopic compound thereof, a crystal form thereof, a nitroxide thereof, a solvate thereof or a solvate of a pharmaceutically acceptable salt thereof.

[1308] Biological experiments
[1309] Example A: In vitro bioactivity evaluation
[1310] The antagonistic properties of the compounds of the present application were determined using the FLIPR (fluorometric imaging plate reader) method as inhibitors of intracellular calcium elevation induced by activation of hP2X4 (human purinergic P2X receptor subtype 4, Accession Number NM_001256796.2) expressed in HEK293 cells (human embryonic kidney 293 cell line, ATCC).
[1311] HEK293 cells stably expressing hP2X4 were maintained in a cell incubator at 37°C, 5% humidity, in DMEM high glucose medium containing 10% FBS (fetal bovine serum, Biosera, FB-1058 / 500), 1% penicillin-streptomycin (Gibco, 15140-122), and 1 mg / mL G418 (CABIOCHE, 345810). 18-24 hours prior to the FLIPR experiment, cells were seeded at a density of 400,000 cells / mL into 384-well plates (10,000 cells / well) and incubated overnight in the cell incubator. On the day of the experiment, the medium was removed and the cells were washed in FLIPR buffer (0.3 mL probenecid (Thermo, P36400), 0.6 mL 1 M HEPES (Invitrogen, 15630080), and 29.1 mL HBSS (Invitrogen, 14065056) per 30 mL of buffer). 20 μL of 0.5x Calcium 6 fluorescent dye (Molecular Devices, R8190) was added to each well and the dye loading incubation was performed at 37°C for 1.5 hours. Subsequently, 10 μL of test compound (dissolved at a concentration of 10 mM in DMSO and serially diluted with buffer) or vehicle was added to each well and allowed to pre-incubate at 37°C for 30 min. The cell plate was then placed in the FLIPR and baseline fluorescence measurements were taken (excitation wavelength 485 nm, emission wavelength 525-535 nm). Agonist (BZ-ATP (Sigma, B6396) at a final concentration of 5 μM) or vehicle (ultrapure water) was then added at 10 μL / well and fluorescence values were measured for 2 minutes at 1 second intervals, and the output fluorescence counts were finally analyzed.
[1312] IC50values obtained using the above method 50 are shown in Table 1.

[1315] wherein A: IC 50 ≤ 10 nM, B: 10 < IC 50≤ 50 nM, C: 50 < IC 50 ≤ 200 nM.
[1316] From the data in Table 1, it can be seen that the compounds of the present application have good P2X4 inhibitory activity, and we particularly prefer compounds having IC 50 ≤ 200 nM, more preferably IC 50 ≤ 50 nM.
[1317] Example B: In vitro cytotoxicity test
[1318] The in vitro cytotoxicity test of the compounds in the present application was determined in HepG2 cells using the CCK-8 method. Logarithmic phase HepG2 cells (Beina Biological Technology Co., Ltd.) were collected, the cell suspension concentration was adjusted, and 50,000 cells / well were plated in a 96-well cell culture plate. The cells were incubated in a 5% cell incubator at 37°C overnight, and when the cell confluence in the plate reached 80-90%, the medium was replaced with various concentrations of test compounds or solvent (DMSO), and incubated in a 5% cell incubator at 37°C for 48 hours. After the treatment was completed, the medium in the plate was discarded, and the cells were washed twice with PBS. 100 μL of CCK-8 working solution (Bi Yun Tian Biological Technology Co., Ltd.) was added to each well, and incubated at 37°C for 1.5 hours in the dark. The OD 450nm value of each well was detected on an enzyme marker, and the CC 50 of each compound was calculated.
[1319] The CC 50 obtained using the above method is shown in Table 2.
[1320] Table 2. CC 50
[1321] Compound HepG2 CC 50 (μM)]]> Compound Compound HepG2 CC 50 (μM)]]> 1 >100 54 >100 2 >100 55 54.3 3 53.6 57 >100 6 >100 60 >100 9 94.92 61 >100 10 >100 62 >100 20 41.62 63 51.72 21 >100 64 >100 22 >100 65 >100 23 >100 66 >100 44 >100 67 >100 46 54.8 72 >100 47 55.5 73 51.23 48 67.9 74 99.78 49 >100 75 54.42
[1322] From the data in Table 2, it can be seen that most of the compounds of the present application have good safety, and the CC 50 range is > 40 μM, which meets the general requirements of in vitro cytotoxicity of compounds, and we prefer compounds having CC 50 > 40 μM, more preferably CC 50 > 100 μM.
[1323] Example C: In vitro metabolic stability test
[1324] The in-vitro metabolic stability of the compounds in the present application is determined by using various in-vitro incubation methods of liver microsomes. In the liver microsomal reaction system (1 mg / mL liver microsomal protein, 25 U / mL 6-phosphoglucose dehydrogenase, 1 mM NADP, 6 mM D-6-phosphoglucose, 5 mM MgCl2), an appropriate amount of the test compound is added, and the reaction is started by incubation in a 37°C water bath. At each time point, 100 μL of the reaction solution is added to a centrifuge tube containing 400 μL of 0°C pre-cooled internal standard working solution (containing 200 ng / mL dexamethasone, diclofenac, tolbutamide, labetalol in acetonitrile) to terminate the reaction. The mixture is centrifuged at 10000 rpm for 10 min at 4°C, and the supernatant is analyzed by LC-MS to obtain the in-vitro metabolic half-life of the test compound in various liver microsomes.
