Description

A fused heterocyclic derivative and its pharmaceutical applications Technical Field

[0001] This invention relates to a compound of general formula (I) or its racemic, stereoisomer, tautomer, pharmaceutically acceptable salt, intermediates and preparation methods thereof, and its use in the preparation of medicaments for treating autoimmune or inflammatory diseases. Background Technology

[0002] Tumor necrosis factor (TNFα), a member of the tumor necrosis factor superfamily, is a cytokine involved in systemic inflammation. It plays a crucial role in the immune response by regulating multiple signaling pathways, including direct inflammatory responses involving immune cells and subsequent immune cell proliferation, as well as programmed cell death or apoptosis. It is a type II transmembrane protein; its precursor consists of 233 amino acids, including a 76-amino acid signal peptide that binds to the cell membrane as a trimer (tmTNFα). Under the action of TNFα convertase (TACE), the membrane-bound TNFα signal peptide is cleaved to form soluble mature TNFα (sTNFα) containing 157 amino acid residues, which is then secreted extracellularly and exerts its biological effects by binding to the tumor necrosis factor receptor (TNFR). TNFα is primarily produced by activated monocytes / macrophages in vivo, but other immune cells such as T cells, B cells, NK cells, and neutrophils also produce TNFα. Its biological functions are diverse. In summary, TNF-α interacts with transmembrane TNFR, controlling cell survival or inducing apoptosis through a unique and complex signaling pathway, thus providing resistance to certain types of infection. Summary of the Invention

[0963] 6. hERG potassium ion channel function test

[0964] Experimental platform: Electrophysiological manual patch-clamp system

[0965] Cell line: Chinese hamster ovary (CHO) cell line stably expressing hERG potassium channels

[0966] Experimental Methods: CHO (Chinese Hamster Ovary) cells stably expressing the hERG potassium channel were used to record hERG potassium channel currents at room temperature using whole-cell patch-clamp technique. Glass microelectrodes were fabricated from glass electrode blanks (BF150-86-10, Sutter) using a stretching device. The tip resistance after perfusion with electrode fluid was approximately 2-5 MΩ. The glass microelectrodes were inserted into the amplifier probe to connect to the patch-clamp amplifier. Clamping voltage and data recording were controlled and recorded using pClamp 10 software via computer, with a sampling frequency of 10 kHz and a filtering frequency of 2 kHz. After obtaining whole-cell recordings, the cells were clamped at -80 mV. The step voltage to induce hERG potassium current (IhERG) was applied from -80 mV with a 2-second depolarization voltage to +20 mV, then repolarized to -50 mV, held for 1 second, and then returned to -80 mV. This voltage stimulation was applied every 10 seconds. After confirming that the hERG potassium current was stable (at least 1 minute), the drug delivery process began. Each compound was administered for at least 1 minute at each test concentration, and at least 2 cells were tested for each concentration (n≥2).

[0967] Data processing: Data analysis and processing were performed using pClamp 10, GraphPad Prism 5, and Excel software. The degree of inhibition of hERG potassium current (the peak hERG tail current induced at -50mV) by different compound concentrations was calculated using the following formula:

[0968] Inhibition%=[1–(I / Io)]×100%

[0969] Where Inhibition% represents the percentage of inhibition of hERG potassium current by the compound, and I and Io represent the amplitude of hERG potassium current before and after drug administration, respectively.

[0970] Compound IC 50 The following equations were fitted and calculated using GraphPad Prism 5 software:

[0971] Y=Bottom+(Top-Bottom) / (1+10^((LogIC 50 -X)×HillSlope))

[0972] Where X is the Log value of the detected concentration of the test sample, Y is the inhibition percentage at the corresponding concentration, and Bottom and Top are the minimum and maximum inhibition percentages, respectively.

[0973] Conclusion: The compounds of the present invention, such as the compounds in the examples, do not exhibit significant hERG inhibitory activity.

[0974] 7. Caco2 Permeability Test

[0975] The experiment used monolayers of Caco-2 cells, incubated in triple parallel in 96-well Transwell plates. A transport buffer solution (HBSS, 10 mM HEPES, pH 7.4±0.05) containing either the compound of the present invention (2 μM) or the control compounds digoxin (10 μM), naldolol (2 μM), and metoprolol (2 μM) was added to the dosing well on the apical or basal side. A transport buffer solution containing DMSO was added to the corresponding receiving well. After incubation at 37±1 °C for 2 hours, the cell plate was removed, and appropriate amounts of sample were transferred from both the apical and basal sides to new 96-well plates. Acetonitrile containing an internal standard was then added to precipitate the protein. The samples were analyzed using LC MS / MS to determine the concentrations of the compound of the present invention and the control compounds. The concentration data were used to calculate the apparent permeability coefficients for transport from the apical to the basal side of the monolayer cells, and from the basal side to the apical side, thereby calculating the efflux rate. Leakage of fluorescein was used to evaluate the integrity of the monolayer cells after 2 hours of incubation.

[0977] Conclusion: The compounds of the present invention, such as the compounds in the examples, have good permeability.

[0978] 8. Experiment on recombinant human TNFα-induced apoptosis in L929 cells:

[0979] First, recombinant human TNFα was dissolved in PBS containing 0.1% BSA to prepare a stock solution of 100 μg / mL, aliquoted, and stored at -80°C. 100 mg of actinomycin D was dissolved in 1 mL of DMSO (Sigma, D2650) to prepare a stock solution of 100 mg / mL, aliquoted, and stored at -20°C. Next, L929 cells were incubated at 225 cm⁻¹. 2 After culturing in culture flasks until confluence reaches 70%–80%, gently wash the cells twice with pre-chilled PBS. Add 5 mL of pre-warmed trypsin-EDTA solution (Solarbio, T1300) and incubate at 37°C for approximately 1 minute. Then, add 10 mL of culture medium (DMEM + 10% FBS, DMEM provided by Hyclone, SH3002201) to neutralize the trypsin. Transfer the cell suspension to a 50 mL centrifuge tube (Biofil, CFT011500), centrifuge at 300–400 x g for 5 minutes, remove the supernatant, and resuspend the cells in 10 mL of pre-warmed culture medium (DMEM + 2% FBS). Mix 20 μL of the cell suspension with 20 μL of 0.2% trypan blue solution (Invitrogen, T10282) for cell counting. Dilute the cells to 2 × 10⁶ cells / mL. 5Cells / mL were added to each well of a 384-well culture plate (Corning, 3570). Then, 100 mg / mL actinomycin D was diluted to 32 μg / mL in culture medium (DMEM + 2% FBS), and 5 μL of this 32 μg / mL actinomycin D was added to each well of the cell culture plate. The culture plate was incubated at 37°C for 1 hour in a 5% CO2 incubator. Next, the test compound was dissolved in DMSO to prepare a 10 mM stock solution, and transferred to a 384-LDV plate at the highest concentration of 10 mM. 4 μL of the solution was transferred to the next well containing 8 μL of DMSO for a 3-fold dilution. The dilution steps were repeated for 10 concentration points from 10 mM to 0.5 mM. Using an Echo 655 (Labcyte), the diluted test compound was transferred to a 384-well plate (Corning, 3764) at a volume of 160 nL per well. DMSO was added to the control wells without the compound. This plate served as the experimental preparation plate. Next, thaw 2.5 μL of recombinant human TNFα and transfer 2 μL to a 1.5 mL centrifuge tube (Axygen, MCT-150-C) containing 198 μL of culture medium (DMEM + 2% FBS) to obtain a 1 μg / mL TNFα solution. Then, take 60 μL of the 1 μg / mL TNFα solution and add it to 15 mL of culture medium (DMEM + 2% FBS) to obtain a 4 ng / mL TNFα working solution (4 times the final concentration). Add 40 μL of 4 ng / mL TNFα working solution to each well of the experimental preparation plate, which contains 160 nmL of the test compound solution or DMSO.
