Description

Technical Field

[0001] This disclosure pertains to the pharmaceutical field and relates to a quinolinamine compound, its preparation method, and its pharmaceutical application. In particular, this disclosure relates to quinolinamine compounds of general formula (I), their preparation methods, pharmaceutical compositions containing such compounds, and their use as therapeutic agents, especially as miRNA modulators and in the preparation of medicaments for treating diseases or conditions improved by regulating miRNA levels. Background Technology

[0002] MicroRNAs (miRNAs) are a class of non-coding single-stranded RNA molecules, approximately 22 nucleotides in length, encoded by endogenous genes. They participate in post-transcriptional gene expression regulation in animals and plants. Each miRNA can have multiple target genes, and several miRNAs can regulate the same gene. This complex network allows for precise regulation of target genes. miR-124 is widely expressed in various tissues throughout the body, especially in brain tissue. Studies have shown that overexpression of miR-124 can promote the transition of activated macrophages to microglia, thereby inhibiting the autoimmune disease encephalomyelitis (Ponomarev ED et al., Nat Med, 2011; 17:67-70). In addition, miR-124 can promote the transformation of macrophages to the M2 type, thereby exerting an anti-inflammatory effect (Veremeyko T, et al., Plos One, 2013; 8:e81774). miR-124 also affects T cell differentiation; the levels of IFN-γ and TNFα in T cells treated with miR-124 are decreased. Overexpression of miR-124 exerts its anti-inflammatory effect by downregulating STAT3 protein, thereby reducing the expression of the inflammatory cytokine IL-17 and inhibiting Th17 cell differentiation (Wei J et al., Cancer Res, 2013; 73:3913-3926). Statistical studies have reported that miR-124 levels in children with ulcerative colitis are significantly lower than in healthy individuals, suggesting that upregulating miR-124 may suppress intestinal inflammatory responses (Koukos G, et al., Gastroenterology, 2013; 145:842-852). Furthermore, the Nakamachi team found that miR-124 was significantly downregulated in synovial cells of rheumatoid arthritis patients compared to osteoarthritis patients (Nakamachi, Y, et al., Arthritis Rheum, 2009; 60:1294-1304). These studies suggest that developing a novel small molecule drug that upregulates miR-124 could be used to effectively treat related inflammatory diseases.

[0003] Inflammation is a protective response of the immune system to local infection or tissue damage; severe inflammation can damage the body. Common manifestations of inflammation include pain, fever, redness, swelling, and loss of function. Inflammatory diseases encompass a variety of conditions, including autoimmune-related inflammatory diseases, inflammatory diseases of the central nervous system (CNS), inflammatory diseases of the joints, inflammatory diseases of the digestive tract, and inflammatory diseases of the skin. Inflammatory bowel disease (IBD) and rheumatoid arthritis (RA) are two of the most common inflammatory diseases and have received widespread attention.

[0004] Inflammatory bowel disease (IBD) is an idiopathic inflammatory bowel disease, clinically manifested as diarrhea, abdominal pain, and even bloody stools. The etiology and pathogenesis of IBD are not fully understood, but it is known that an abnormal inflammatory response caused by the intestinal mucosal immune system plays a crucial role in its pathogenesis. Environmental, genetic, infectious, and immune factors can all contribute to the disease. IBD typically refers to ulcerative colitis (UC) and Crohn's disease (CD). Ulcerative colitis is a continuous inflammation of the colonic mucosa and submucosa, usually starting in the rectum and gradually spreading to the entire colon. Crohn's disease can affect the entire digestive tract, presenting as a discontinuous, full-thickness inflammation, most commonly affecting the terminal ileum, colon, and perianal region. IBD is typically characterized by excessive immune cell invasion of the intestinal mucosa, an imbalance of T cell subsets including Th17, Th1, and Treg, and overactivated macrophages and dendritic cells. Currently marketed or clinically tested drugs include JAK inhibitors and TNFα antibodies that reduce inflammatory responses, antibodies against IL-12 and IL-23 that inhibit Th1 and Th17 differentiation, and integrin α4β7 antibodies that block inflammatory cell infiltration.

[0005] Rheumatoid arthritis (RA) is a systemic inflammatory disease affecting the endothelial tissue of joints (called the synovium). It is characterized by polyarticular, symmetrical, and invasive joint inflammation of the small joints of the hands and feet, often accompanied by extra-articular organ involvement, leading to joint deformities and loss of function. Inflammatory cytokines (such as tumor necrosis factor-α, interleukins IL-1 and IL-6) play important roles in the pathogenesis of RA. Treatment typically involves disease-modifying small molecule antirheumatic drugs (DMARDs) or biologics such as TNF-α inhibitors. However, patients who initially respond to these drugs often become unresponsive after several years of use. Therefore, there is a need to develop treatments with novel mechanisms of action that are effective and safe for long-term use.

[0434] The compounds disclosed herein include their isotopic derivatives. The term "isotopic derivative" refers to a compound whose structure differs only in the presence of one or more isotopically enriched atoms. For example, compounds having the structure disclosed herein, using "deuterium" or "tritium" instead of hydrogen, or using... 18 F-fluorine labeling ( 18 F isotopes) can be used instead of fluorine, or... 11 C-、 13 C- or 14 C-enriched carbon ( 11 C-、 13 C- or 14 C-carbon labeling; 11 C-、 13 C- or 14Compounds in which carbon atoms are replaced by C-isotopes are within the scope of this disclosure. Such compounds can be used as analytical tools or probes in biological assays, or as in vivo diagnostic imaging tracers for diseases, or as tracers for pharmacodynamic, pharmacokinetic, or receptor studies. In the deuterated form, each available hydrogen atom bonded to a carbon atom can be independently replaced by a deuterium atom. Those skilled in the art can synthesize the deuterated form of the compound with reference to relevant literature. Commercially available deuteration starting materials can be used in the preparation of the deuterated form of the compound, or they can be synthesized using conventional techniques with deuteration reagents, including but not limited to deuterated boranes, trideuterated borane tetrahydrofuran solutions, deuterated lithium aluminum hydride, deuterated iodoethane, and deuterated iodomethane. Deuterated compounds generally retain activity comparable to undeuterated compounds, and better metabolic stability can be achieved when deuterated at certain specific sites, thus providing certain therapeutic advantages. Compared to undeuterated drugs, deuterated drugs offer advantages such as reduced toxicity, increased drug stability, enhanced efficacy, and prolonged biological half-life. All isotopic variations of the compounds disclosed herein, regardless of radioactivity, are included within the scope of this disclosure. Each available hydrogen atom bonded to a carbon atom may be independently replaced by a deuterium atom, wherein deuterium substitution may be partial or complete, with partial deuterium substitution referring to at least one hydrogen atom being replaced by at least one deuterium atom. When a position is specifically designated as deuterium (D), that position should be understood as having a deuterium abundance at least 1000 times greater than the natural abundance of deuterium (which is 0.015%) (i.e., at least 15% deuterium incorporation). The compounds in the examples having a natural abundance greater than deuterium can be at least 1000 times abundant deuterium (i.e., at least 15% deuterium doping), at least 2000 times abundant deuterium (i.e., at least 30% deuterium doping), at least 3000 times abundant deuterium (i.e., at least 45% deuterium doping), at least 3340 times abundant deuterium (i.e., at least 50.1% deuterium doping), at least 3500 times abundant deuterium (i.e., at least 52.5% deuterium doping), at least 4000 times abundant deuterium (i.e., at least 60% deuterium doping), or at least 4500 times abundant deuterium (i.e., at least 67.5% deuterium doping).

[0435] The compounds disclosed herein can exist in specific stereoisomer forms. The term "stereoisomer" refers to isomers with the same structure but different spatial arrangements of atoms. These include cis and trans (or Z and E) isomers, (-)- and (+)- isomers, (R)- and (S)- enantiomers, diastereomers, (D)- and (L)- isomers, tautomers, trans-blocked isomers, conformational isomers, and mixtures thereof (such as racemic mixtures and mixtures of diastereomers). Substituents in the compounds disclosed herein may contain additional asymmetric atoms. All such stereoisomers and mixtures thereof are included within the scope of this disclosure. For all carbon-carbon double bonds, even if only one configuration is named, both Z-type and E-type are included. Optically active (-)- and (+)- isomers, (R)- and (S)- enantiomers, and (D)- and (L)- isomers can be prepared by chiral synthesis, chiral reagents, or other conventional techniques. This disclosure discloses an isomer of a compound, which can be prepared by asymmetric synthesis or by derivatization with a chiral auxiliary, or, when the molecule contains a basic functional group (such as an amino group) or an acidic functional group (such as a carboxyl group), by forming a salt of the diastereomer with a suitable optically active acid or base, followed by diastereomer resolution using conventional methods known in the art to obtain the pure isomer. Furthermore, the separation of enantiomers and diastereomers is typically performed by chromatography.

[0436] The compounds disclosed herein can exist in various tautomer forms, and all such forms are included within the scope of this disclosure. The terms "tautomer" or "tautomer form" refer to a structural isomer that exists in equilibrium and readily transforms from one isomer to another. This includes all possible tautomers, i.e., existing as a single isomer or as a mixture of said tautomers in any proportion. Non-limiting examples include: keto-enols, imine-enamines, lactam-lactamimides, etc. An example of a lactam-lactamimide in equilibrium is shown below:

[0442] "Optional" or "optional" means that the event or situation subsequently described may, but does not have to, occur; the description includes the possibility or possibility that the event or situation may or may not occur. For example, "optionally halogenated or cyano-substituted C..." 1-6 "Alkyl" means that halogens or cyano groups may or may not be present. This description includes cases where alkyl groups are substituted by halogens or cyano groups and cases where alkyl groups are not substituted by halogens or cyano groups.

[0443] "Substituted" refers to one or more hydrogen atoms in a group, preferably 1 to 5, more preferably 1 to 3 hydrogen atoms, which are independently substituted by the corresponding number of substituents. Those skilled in the art can determine possible or impossible substitutions without much effort (through experimentation or theory). For example, an amino or hydroxyl group with free hydrogen may be unstable when combined with a carbon atom having an unsaturated bond (such as an alkene).

[0444] "Pharmaceutical composition" means a mixture containing one or more of the compounds described herein or their pharmaceutically acceptable salts or prodrugs, along with other chemical components, such as pharmaceutically acceptable carriers and excipients. The purpose of a pharmaceutical composition is to facilitate administration to a living organism, thereby promoting the absorption of the active ingredient and its biological activity.

[0445] "Pharmacologically acceptable salt" refers to the salt of the compounds disclosed herein, which may be selected from inorganic or organic salts. Such salts are safe and effective when used in mammals and possess the expected biological activity. The salt can be prepared separately during the final isolation and purification of the compound, or by reacting a suitable group with a suitable base or acid. Bases commonly used to form pharmaceutically acceptable salts include inorganic bases, such as sodium hydroxide and potassium hydroxide, and organic bases, such as ammonia. Acids commonly used to form pharmaceutically acceptable salts include both inorganic and organic acids.

[0446] For the purposes of pharmaceuticals or pharmacologically active agents, the term "therapeutic effective amount" refers to the amount of a drug or agent sufficient to achieve or at least partially achieve the intended effect. The determination of the effective amount varies from person to person, depending on the recipient's age and general condition, as well as the specific active substance. The appropriate effective amount in a particular case can be determined by a person skilled in the art based on routine testing.

[0447] As used herein, the term "pharmaceutically acceptable" means that these compounds, materials, compositions, and / or dosage forms are suitable for contact with patient tissues without excessive toxicity, irritation, allergic reactions, or other problems or complications, within reasonable medical judgment, have a reasonable benefit / risk ratio, and are effective for their intended use.

[0448] As used herein, the singular forms of “a,” “an,” and “the” include plural references, and vice versa, unless the context clearly indicates otherwise.

[0449] When the term "about" is applied to parameters such as pH, concentration, temperature, etc., it indicates that the parameter can vary by ±10%, and sometimes more preferably within ±5%. As those skilled in the art will understand, when a parameter is not critical, figures are usually given for illustrative purposes only, not as limitations.

[1110] 3. Results

[1111] 3.1 Effect of compound 1 disclosed herein on body weight of DSS-induced UC mice

[1112] The results of the weight test showed that ( Figure 1 Compared with the normal control group, mice in the DSS model group experienced a significant decrease in body weight starting from day 4, with the rate of weight loss gradually increasing, reaching 30.0% by day 10 (P<0.001). Compared with the DSS model group, all treatment groups showed a significant recovery in body weight starting from day 7. By day 10, the weight loss rates for ABX-464 (qd), ABX-464 (bid), and compound 1 (bid) disclosed in this publication were reduced to 14.1% (P<0.001), 10.3% (P<0.001), and 0.4% (P<0.001), respectively. At the experimental endpoint, the rate of weight recovery, from strongest to weakest, was: compound 1 (50 mg / kg, bid) > ABX-464 (50 mg / kg, bid) > ABX-464 (50 mg / kg, qd).

[1113] 3.2 Effect of Compound 1 of this disclosure on colon length in DSS-induced UC mice

[1114] The colon length results showed ( Figure 2Compared with the normal control group, the colon length in the DSS model group was significantly shortened (P<0.001), only 75.4% of that in the normal control group. Compared with the DSS model group, the colon length in all treatment groups was significantly increased. The colon lengths of ABX-464 (qd), ABX-464 (bid), and compound 1 of this disclosure (bid) were 85.5% (P<0.05), 89.3% (P<0.05), and 91.9% (P<0.01) of the normal control group, respectively. The colon length from longest to shortest was: compound 1 of this disclosure 50 mg / kg (bid) > ABX-464 50 mg / kg (bid) > ABX-464 50 mg / kg (qd).

[1115] 4. Conclusion

[1116] The DSS model serves as a culprit-like animal model for ulcerative colitis (UC) induced by IBD. Factors affecting the model's effectiveness include the molecular weight (36,000-50,000), batch number, storage configuration, mouse housing environment, and strain of the DSS. This modeling attempt was relatively successful, showing significant changes in mouse body weight and colon length. Results showed that compound 1 exhibited superior efficacy compared to the positive control drug ABX-464 in terms of body weight and colon length. Therefore, both 50 mg / kg ABX-464 and compound 1 have certain preventative and therapeutic effects on DSS-induced UC, with compound 1 showing the strongest efficacy, exceeding that of the same dose of ABX-464.

[1145] III. Experimental Procedure

[1146] The effect of the compound on miR-124 expression levels was detected in T cells activated by CD3 / CD28 antibody. After treatment with the compound, total RNA was extracted from the activated T cells, and the cDNA obtained from reverse transcription was used as a template. Quantification was performed using SYBR Green real-time PCR with specific miR-124 primers.

[1147] T cell isolation: Purchased human peripheral blood mononuclear cells (PBMCs), counted and centrifuged, washed once with separation buffer (PBS pH 7.4, containing 0.5% BSA and 2mM EDTA), discarded the supernatant, and divided into 1×10⁻⁶ cells per cell. 7 Add 40 μL of buffer and 10 μL of pan T cell biotinylated antibody (pan T Cell Biotin-Antibody Cocktail) to each cell, resuspend the precipitate, mix well, and incubate at 4°C for 5 minutes. After incubation, repeat the process at 1 × 10⁻⁶ cells / cell. 7 Add 30 μL of buffer and 20 μL of Pan T Cell MicroBeads Cocktail to each cell, mix well, and incubate at 4°C for 10 minutes. Pre-wash the separation column (LS column) with 3 mL of cell separation buffer, then pass the cell suspension through the column. After passing the cell suspension through the column, wash the column three times with 1 mL of cell separation buffer. Collect the eluent cell solution in a 15 mL centrifuge tube; this is the enriched T cells. Count the cells at a ratio of 1 × 10⁻⁶ cells / mL. 6 Add cells at a density of 10% FBS and 40 U / mL IL-2 to RPMI 1640 medium (complete medium) and store on ice for later use.

[1148] T cell activation: per 1×10 6Add 25 μL of activating magnetic beads to each cell. Take the corresponding amount of activated CD3 / CD28 magnetic beads for T cell activation and place them in a 1.5 mL centrifuge tube. Shake the tube for approximately 30 seconds before aspirating. Wash the activated magnetic beads three times with culture medium at a volume ratio greater than 1:1. Remove all washings on the last wash and resuspend the activated magnetic beads in an equal volume of complete culture medium. Add the washed activated magnetic beads to the cell resuspension and mix thoroughly. Add 3 mL of cells to each well of a six-well plate and incubate at 37°C in a 5% CO2 incubator for 2 days.

[1149] Compound preparation: The stock solution of the compound was 20 mM, diluted to 200 μM with DMSO, and then diluted 4-fold with complete culture medium to 50 μM (50×). Mix well and set aside. A 4-fold dilution with 25% DMSO served as a negative control. T cells activated for two days were pipetted and placed on a magnetic rack with 1.5 mL centrifuge tubes. The activation beads were removed, and the cell suspension was collected. After cell counting, the cells were centrifuged at 300 x g for 10 min, the supernatant was discarded, and the cells were resuspended to 1.02 × 10⁻⁶. 6 Add 980 μL of cell suspension and 20 μL of 50× compound to each well of a 24-well plate, bringing the final compound concentration to 1 μM. Incubate the cells at 37°C in a 5% CO2 cell culture incubator for 3 days.

[1150] RNA extraction: Collect T cells by centrifugation at 1500 rpm for 3 minutes, wash once with PBS, and discard the supernatant after centrifugation. Extract total RNA from cells using a small RNA extraction kit according to the manufacturer's instructions. Add 700 μL of Trizol cell lysis buffer to the cell pellet, mix well by pipetting, and incubate at room temperature for 5 minutes. Add 140 μL of chloroform, vortex to mix, and incubate at room temperature for 3 minutes. Centrifuge the chloroform-cell lysis buffer mixture at 12000 xg for 15 minutes at 4°C. Transfer the supernatant to a new RNase-free centrifuge tube, add 1.5 volumes of anhydrous ethanol, and mix several times by pipetting. Transfer the solution to an RNA adsorption column and centrifuge at 8000 xg for 15 seconds. Wash the column once with 700 μL of RWT solution, centrifuge at 8000 xg for 15 seconds, wash twice with 500 μL of RPE solution, and centrifuge at 8000 xg for 2 minutes. Transfer the adsorption column to a new 2 mL centrifuge tube and centrifuge at 12000 x g for 1 min to remove residual washing buffer. Transfer the adsorption column to a new 1.5 mL centrifuge tube, add 30-50 μL of RNase-free water, centrifuge at 12000 x g for 2 min, and collect the RNA solution. Measure the RNA concentration using a spectrophotometer. Store the RNA solution at -80°C.

[1151] Reverse transcription: Place the extracted RNA template on ice. Remove the small RNA reverse transcription kit and thaw a portion of its components (containing 5×miScript HiSpec Buffer, 10×miScript nucleics Mix, and RNase-free water) at room temperature. Thaw the miScript Reverse Transcriptase mix component on ice. Each reaction (10 μL) consists of: 5×miScript HiSpec Buffer (2 μL), 10×miScript nucleics Mix (1 μL), miScript Reverse Transcriptase mix (1 μL), RNase-free water (2 μL), and RNA template (4 μL). Prepare the reaction on ice. Place the samples in a PCR instrument and set the program as follows: 37℃, 60 minutes; 95℃, 5 minutes; store at 4℃. The completed reaction sample is the cDNA sample.

[1152] Quantitative real-time PCR: The transcriptional level of miR-124 was detected using SYBR Green staining, while the transcriptional level of the housekeeping gene U6 was detected as an internal control. Thaw all reagents required for the small RNA SYBR Green PCR kit to room temperature. Dilute each cDNA sample template 10-fold with RNase-free water, then dilute 5-fold. Prepare the reaction mixture according to Table 1 below, and add the reaction mixture to a 96-well PCR plate. Seal the plate with sealing film and centrifuge. Perform the PCR reaction on a quantitative real-time PCR instrument according to the steps in Table 2.
