Description

A compound and uses thereof

[0001] This application claims priority to Chinese patent application PCT / CN2024 / 101586 with a filing date of 2024 / 6 / 26, and Chinese patent application PCT / CN2024 / 136275 with a filing date of 2024 / 12 / 3. This application incorporates the full text of the above-mentioned Chinese patent applications. TECHNICAL FIELD

[0002] The present application belongs to the field of medicinal chemistry, and relates to a compound and uses thereof. BACKGROUND

[0003] Toll-like receptors (TLRs) are a conserved class of type I transmembrane proteins in the immune system that recognize conserved molecular patterns (pathogen-associated molecular patterns, PAMPs) present in pathogen proteins, lipids, and nucleic acids. Activation of TLRs can trigger host defense mechanisms, such as secretion of inflammatory cytokines, induction of interferon pathways, and activation of B cells and neutrophils. Endosomal TLRs, including TLR3, TLR7 / 8, and TLR9, can recognize double-stranded RNA (dsRNA), GU-rich single-stranded RNA (ssRNA), and non-methylated single-stranded DNA (ssDNA), respectively. Abnormal activation of these nucleic acid-sensing endosomal TLRs is believed to be a potential driving factor for autoimmune diseases such as systemic lupus erythematosus (SLE) and Sjogren's syndrome (SjS).

[0004] Genetic and functional evidence suggests that chronic over-activation of TLR7 / 8 by endogenous single-stranded RNA is a driving factor for several systemic autoimmune diseases. For example, gain-of-function mutations in TLR7 were found to exist in children with severe autoimmune disease, and expression of this mutation in mice led to a fatal lupus-like disease. Overexpression of TLR7 or TLR8 also triggered similar lupus-like diseases.

[0005] ​Enhanced activation of TLR7 and TLR8 contributes to the cellular mechanisms of multiple systemic autoimmune diseases. For example, patient autoantibodies form RNA-containing immune complexes (ICs) with ribonucleoproteins (RNPs) that drive type I interferon (IFN) release from plasmacytoid dendritic cells (pDCs) in a TLR7-dependent manner. IFNs, as well as an elevated IFN-stimulated gene signature, are characteristic features of SLE patients. Neutrophils are activated through TLR8, autoreactive B cells internalize RNA-containing autoantigens to activate TLR7, and autoantigens containing complex RNA are phagocytosed by monocytes / dendritic cells (DCs) to activate TLR8. In summary, enhanced activation of TLR7 / 8 increases the secretion of antinuclear antibodies (ANAs) by autoreactive B cells, pDCs, and monocytes / DCs and sustains a self-sustaining feedback loop of inflammation and tissue damage.

[0006] Accordingly, TLR7 / 8 antagonists can help break this vicious cycle in patients, and the development of small molecule inhibitors is an attractive approach to treat such autoimmune diseases. SUMMARY

Because of their ease in administration, tablets and capsules are the preferred oral dosage unit form, and the use of solid pharmaceutical carriers is preferred for the creation of these dosage forms. Alternatively, the tablets can be coated by standard aqueous or nonaqueous techniques.

[0087] Tablets containing the compositions of the present application can be prepared by compression or molding, optionally with one or more accessory ingredients or adjuvants. Compressed tablets can be prepared by compressing, in a suitable machine, the active ingredient in a free-flowing form, such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent.

Furthermore, the compositions can be in the form of sterile powders for the extemporaneous preparation of such sterile injectable solutions or dispersions. In all cases, the final injectable form must be sterile and must be effectively fluid for easy syringability. The pharmaceutical compositions must be stable under the conditions of manufacture and storage; thus, preferably should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyols (such as glycerol, propylene glycol and liquid polyethylene glycols), vegetable oils, and

[0090] The pharmaceutical compositions of the present application can be in a form suitable for local use, such as an aerosol, cream, ointment, lotion, dusting powder, or the like.

[0091] The pharmaceutical compositions of this application can be in a form suitable for rectal administration wherein the carrier is a solid. Preferably, the composition takes the form of suppositories for rectal administration of the drug. Suitable carriers include cocoa butter, other materials often used for making suppositories, and the like. Suppositories forms can be conveniently prepared by first forming a mixture of the composition with a soft, malleable, easily deformed carrier consisting of, for example, cocoa butter and / or other materials often used for making suppositories and then shaping the mixture into the desired shape and size.

[0092] In addition to the carrier ingredients, the pharmaceutical formulations described above can include one or more additional ingredients such as diluents, buffers, flavoring agents, binders, surface active agents, thickeners, lubricants, preservatives (including antioxidants), and the like. Further, other adjuvants can be included to render the formulation isotonic with the blood of the intended recipient.

[0218] I. TLR7 inhibitory activity screening test - HEK-Blue-TLR7 reporter assay

[0219] HEK-Blue TM hTLR7 cells are engineered from the HEK293 cell line for the study of the TLR7-dependent NF-κΒ pathway. These cells express the human TLR7 gene and an NF-κΒ / AP-1 inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene. HEK-Blue TM hTLR7 cells are able to respond strongly and stably to TLR7-specific ligands, allowing the screening of TLR7-specific agonists or inhibitors.

[0220] 1. Cell preparation: HEK-Blue TM hTLR7 cells were collected and resuspended in DMEM (11995065, Gibco) cell culture medium containing 10% FBS (#76294-180, Avantar). Cell density was determined using a cell counter. An appropriate amount of cell suspension was removed from the centrifuge tube to be sufficient to prepare 10000 cells / 40 μL of system. 40 μL of HEK-Blue™-TLR7 cell suspension was plated in each well of a 384-well plate (#3764, Corning).

[0221] 2. Compound preparation and addition: Compound powder was prepared into a 10 mM stock using DMSO, 3 ul of the stock was added to 6 ul of DMSO for a 3-fold dilution, test compounds were dispensed onto the cell plate using an Echo 650 Series acoustic liquid handler (Echo 650, Beckman Coulter), final test compound concentrations were: 10000 nM, 3333.33 nM, 1111.11 nM, 370.37 nM, 123.46 nM, 41.15 nM, 13.72 nM, 4.57 nM and 1.52 nM. After 0.5 hours R848 (tlrl-r848, invivogen) was added to the well plate using an Echo 650 Series acoustic liquid handler. The well plate was incubated in a humidified tissue culture incubator (CLM-240B-8-TC, ESCO) for 24 hours.

[0222] 3. Detection and readout: To each well of a new 384 well plate 18 μΙ_ of prepared Quanti-Blue™ solution (rep-qbs3, InvivoGen) was added. 2 μΙ_ of supernatant was transferred to the Quanti-Blue™ solution and incubated for 60 minutes at room temperature. Data on the plate was read using a microplate reader in 384 well absorbance 620-655 mode (PHERAstar FSX, BMG).

[0223] 4. Data analysis: Data analysis, curve fitting and reporting was performed using the Dose-response one-site 205 model of IDBS XLfit.

[0224] Calculation formula Inhibition% = (Ave_H-Sample) / (Ave_H-Ave_L) (H = Ave(DMSO), L = Ave(Unstin))

[0225] IC50 fitting formula: IC50 values of compounds were fitted using a non-linear regression equation, formula: Y = Bottom + (Top-Bottom) / (1 + 10^((LogIC50-X)*HillSlope))

[0229] II. Assessment of hERG potassium ion channel safety by automated patch clamp technology

[0230] This method is to apply SyncroPatch 384i automated patch clamp test system produced by Nanion Company to evaluate the inhibitory effect of the test compound on potassium ion voltage-gated channel hERG.

[0231] 1. Preparation of test compound solution: The test compound powder is dissolved in DMSO and prepared into a stock solution with a final concentration of 10 mM. The stock solution is diluted into other concentration solutions with a gradient of 1:3 ratio using DMSO as the solvent. Before the experiment, the test compound gradient solution is diluted into working solutions with corresponding concentrations by 1:500 ratio using extracellular fluid, and the final concentration is 20 μM, while the 60 μM working solution is diluted by 3:500 ratio from the 10 mM stock solution. Note: when dosing, the working solution will be added into the chip well containing the same volume of extracellular fluid with a volume ratio of 1:1, so the actual final gradient concentration of dosing should be: 30 μM, 10 μM.

[0232] 2. Cell culture and treatment: CHO cell strain stably expressing hERG ion channel is purchased from B'SYS GmbH Company in Switzerland. The cell strain is cultured in F-12 (HAM) medium containing 10% FBS buffer, 100 U / mL Penicillin-Streptomycin, 100 μg / mL Hygronycin and 100 μg / mL G418. The cells are digested and prepared into a final density of (5-7.5)*10 5 cells / mL into a 10 cm low adsorption cell culture dish, and incubated at 4-10°C for 10 minutes. Then the cells are transferred into a Teflon plate specially designed for SyncroPatch 384i system, and placed into the cell incubation tank of the automated patch clamp system, and incubated at 15°C, 200 rpm for 30 minutes before starting the experiment.

[0233] 3. Test of inhibitory effect of test compound on hERG current: First, the cells are perfused with extracellular fluid containing 0.1% DMSO for 6 times to determine the stable hERG current as the detection baseline, and the baseline current value is the average of 5 stable sampling points. After the hERG current remains stable, the solution containing the test compound is perfused around the cells, and 10 minutes are waited for the compound to fully act on the cells and record the hERG current synchronously. After the current tends to be stable, 5 stable hERG current values are read, and their average is taken as the final current value at a specific concentration.

[0234] 4. Data reading and analysis: Data were exported by Data control 384 software.

[0235] 1) After perfusion of blank solvent or compound gradient solution, the average of 5 consecutive current values was obtained as "tail current size 空白 " and "tail current size 化合物 ", respectively.

[0236] 2) The percentage of current inhibition was calculated by the following formula: tail current inhibition rate = (1 - tail current size 化合物 - tail current size 阳性对照 / tail current size 空白 - tail current size 阳性对照 ) x 100%
