Abstract
Description
Technical Field
[0001] This invention relates to the field of medicinal chemistry. Specifically, this invention relates to compounds having dual inhibitory activity against JNK-NLRP3, pharmaceutical compositions comprising said compounds, and their use in the preparation of remedies for JNK-NLRP3-related diseases. Background Technology
[0002] JNK (c-Jun N-terminal kinase) is a member of the MAPK (mitogen-activated protein kinase) family and plays a crucial role in cellular responses to various abiotic and biotic stresses. JNK regulates important physiological processes, including neuronal function, immune function, and embryonic development, by influencing gene expression, cytoskeletal protein dynamics, and cell death / survival pathways. Dysregulation of the JNK signaling pathway is associated with the development and progression of several human diseases, including diabetes, inflammatory diseases, and neurodegenerative diseases.
[0003] NLRP3 (NOD-like receptor protein 3) is a member of the NLR (NOD-like receptor) family. It forms the inflammasome complex in the cytoplasm and participates in the regulation of the innate immune system and inflammatory responses. The NLRP3 inflammasome can recognize pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), activate caspase-1, and promote the maturation and secretion of IL-1β and IL-18, thereby mediating the inflammatory response. Aberrant activation of the NLRP3 inflammasome is associated with a variety of diseases, including metabolic diseases, autoinflammatory diseases, and tumors.
[0004] In some studies, it has been found that JNK can promote the activation of the NLRP3 inflammasome by directly phosphorylating NLRP3. This phosphorylation is one of the key steps in the activation of the NLRP3 inflammasome. For example, in diabetic nephropathy, the Syk / JNK / NLRP3 signaling pathway is involved in the pathogenesis of kidney disease, and the activation of JNK is associated with the expression level of the NLRP3 inflammasome.
[0005] Furthermore, JNK activation can also affect the NLRP3 inflammasome in other ways, such as by influencing NLRP3 ubiquitination and self-polymerization. In certain infectious diseases, such as Streptococcus pneumoniae infection, the ALK / JNK signaling pathway activates the NLRP3 inflammasome, thereby affecting pyroptosis and inflammatory responses.
[0006] In summary, the relationship between JNK and NLRP3 plays a crucial role in the development and progression of inflammatory diseases. JNK activation can promote the assembly and activation of NLRP3 inflammasomes, thereby influencing inflammatory responses and cell death processes. These findings offer potential therapeutic approaches for inflammatory diseases or other JNK & NLRP3-related conditions.
[0007] Aberrant activation of JNK and NLRP3 plays a crucial role in various diseases, and the two may have synergistic effects. Dual-target compounds offer multiple advantages, simplifying treatment regimens, improving patient compliance, reducing drug interactions, and enhancing therapeutic efficacy compared to simple drug combinations. Therefore, the development of dual-target drugs targeting JNK and NLRP3 has significant clinical implications and promising application prospects for the treatment of inflammatory diseases, cancer, and other related conditions.

[0078] Terminology Definition
[0079] The terms used herein to refer to groups, substituents, or structures of compounds have the same meaning as understood by those skilled in the art. For clarity, the terms used in this specification are defined as follows.
[0080] In this invention, "a", "a type" or "a class" means at least one / a type or more than one / a type.
[0081] In this paper, expressions such as "1-n" refer to groups having 1 to n carbon atoms. For example, "1-10" indicates that a group has 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 carbon atoms; similarly, "C6~C10" indicates that a group has 6, 7, 8, 9, or 10 carbon atoms. Furthermore, the descriptions of the range of carbon atom counts in this paper also include sub-ranges. For instance, when referring to 1-10 carbon atoms, this paper also includes cases with 1-9, 1-8, 1-7, 1-6, 1-5, 1-4, and 1-3 carbon atoms.
[0082] As used herein, the term "alkyl" has the same meaning as commonly understood by those skilled in the art, referring to various saturated or unsaturated straight-chain, side-chain, or cyclic hydrocarbon groups. For example, the alkyl group referred to herein refers to a lower alkyl group with 1-10 carbon atoms; preferably a lower alkyl group with 1-8 carbon atoms; more preferably a lower alkyl group with 1-6 carbon atoms. In specific embodiments, the alkyl group referred to herein includes, but is not limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl, pentyl, hexyl, heptyl, etc. Similarly, the terms "alkenyl" or "alkynyl" as used herein refer to various unsaturated straight-chain, side-chain, or cyclic hydrocarbon groups containing carbon-carbon double or triple bonds.
[0083] As used herein, the terms "aryl" or "aromatic ring" have the same meaning as commonly understood by those skilled in the art, referring to a cyclic conjugated aromatic system; for example, the term "C6-C10 aryl" refers to an aromatic cyclic group with 6 to 10 carbon atoms that does not contain heteroatoms in the ring, such as phenyl or naphthyl. The term "heteroaryl," as used herein, refers to a cyclic conjugated aromatic system containing one or more heteroatoms such as N, O, or S in the ring; for example, pyridyl or pyrazinyl.
[0084] As used herein, the term "halogen" has the meaning commonly understood by one of ordinary skill in the art. In specific embodiments, halogen refers to fluorine, chlorine, bromine, or iodine.
[0085] As used herein, the term "substitution" refers to the replacement of one or more hydrogen atoms on a specific group by a specific substituent. A specific substituent may be a substituent described above or a specific substituent appearing in the various embodiments. Therefore, in this invention, the substituents in Formula 1 can each independently be the corresponding group in the specific compounds of the embodiments; that is, this invention includes combinations of the substituents in Formula 1 above, as well as combinations of some of the substituents shown in Formula 1 with other specific substituents appearing in the embodiments.
[0086] Unless otherwise specified, a substituted group may have a particular substituent at any substituted site on that group, and the substituents may be the same or different at each position. Cyclic substituents, such as heterocyclic groups, may be attached to another ring, such as a cycloalkyl group, thereby forming a spirobicyclic system, for example, where the two rings share a common carbon atom.
[0087] In particular, the various substituents defined above also include groups formed by further substitution of these substituents, which may also contain other groups. For example, the hydrogen atoms on alkyl and aryl groups are replaced by amino, halogen, or other groups to become groups belonging to the above definitions.
[0088] As used herein, the term "optionally substituted" means that a group may be substituted or not substituted. In specific embodiments, "optionally substituted" means optionally substituted by one or more substituents selected from the following: cyano, halogen, hydroxyl, optionally substituted amino, nitro, carboxyl, ester, oxo, deuterated, optionally substituted C 1-3 Alkyl, optionally substituted C 1-3 Alkoxy, optional substituted C 1-3 Acyloxy group, optionally substituted C 5-10 Aryl or heteroaryl, optionally substituted 3-7 membered cycloalkyl or heterocyclic, optionally substituted sulfonyl, optionally substituted acyl.
[0089] The compounds of the present invention
[0090] The compound of this invention is a dual-target compound; that is, a single-component compound that can act on two or more molecular targets simultaneously. This drug design strategy is of great significance for the treatment of complex diseases, such as cancer, metabolic diseases, autoimmune diseases, and neurodegenerative diseases. Compared with single-target drugs, dual-target compounds have the following advantages: (1) Improved therapeutic effect: By acting on multiple key aspects of the disease simultaneously, dual-target compounds may produce a synergistic effect, thereby improving the therapeutic effect; (2) Reduced drug resistance: Since the drug acts on multiple targets, disease cells need to generate drug resistance mutations on multiple targets simultaneously to evade the drug's effect, thus making it more difficult to develop drug resistance; (3) Reduced side effects: The synergistic effect of dual targets can achieve therapeutic effects at lower doses, and side effects can be reduced by lowering the dose of single-target drugs; (4) Simplified treatment regimen: Compared with multi-drug combination therapy, dual-target compounds can simplify the treatment regimen, make it easier for patients to take, and improve compliance.

Laboratory Animals: Male ICR mice (6-12 weeks old) were purchased from the Laboratory Animal Center of Hangzhou Normal University and housed in a temperature- and humidity-controlled environment. Husbandry and experimental use were carried out in accordance with the "Guidelines for the Husbandry, Management and Use of Laboratory Animals".
[0253] II. Experimental Methods:
[0254] 1. Isolation and Differentiation of BMDM Cells
[0255] 1) Mice leg bone harvesting: Mice were euthanized by dislocation, and their legs and backs were disinfected with sufficient 75% ethanol. The hind limb was then detached from the greater trochanter at the base of the thigh using scissors. After removing the muscle tissue, the limb was placed in cold PBS. (This step was performed in a laminar flow hood; subsequent steps were transferred to the cell culture room.)
[0256] 2) BMDM Cell Extraction and Induction: Rinse the leg bone with PBS to remove excess muscle, approximately 2-3 times. Cut the femur and tibia at both ends with scissors. Using a 1mL syringe, draw cold induction medium and blow bone marrow from the femur and tibia, repeating this process 3 times until no obvious red color is visible inside the leg bone. Use a pipette to repeatedly pipette the medium containing bone marrow cells to disperse cell clumps, transfer to a 15mL centrifuge tube, and centrifuge at 1500rpm for 5min. Discard the supernatant, add approximately 1-2mL of erythrocyte lysis buffer to resuspend the cells, and pipette to separate the cells into single cells. After incubating at room temperature for 5min, add 10mL of medium to terminate the reaction. Filter through a 0.45μm cell filter membrane and centrifuge at 1500rpm for 5min. Discard the supernatant, resuspend the cells, and count the cells. Resuspend the cells in 1640 medium (10% FBS, 2% PS) containing 20ng / mL M-CSF factor, and transfer the cell suspension to a no-treated disposable bacterial culture dish for culture.
[0257] 2. Activation of the classic NLRP3 inflammasome
[0258] Using well-differentiated BMDM cells (4-6 days old), discard the culture supernatant and wash the cells with an appropriate amount of PBS. Add 10 mL of DMEM medium and scrape the cells off using a cell scraper. Resuspend the cells in a centrifuge tube and centrifuge at 1500 rpm for 10 min. Remove the supernatant, resuspend the BMDM cells in DMEM medium, and divide them into 12-well plates, ensuring approximately 5 × 10⁶ cells per well. 5 / mL. The next day, 500 μL of Opti-MEM medium (containing 500 ng / mL LPS) was added to each well of BMDM cells for pretreatment for 4-5 hours. The compound was weighed using an analytical balance and placed in a sterile centrifuge tube, then dissolved in dimethyl sulfoxide (DMSO) to prepare the compound at the desired concentration. The compound was treated with the drug for 30 min, followed by stimulation with 10 μM Nigericin for 60 min. The cell supernatant (SN) and cell lysis buffer (Input) were collected. Based on the obtained cell supernatant (SN) and cell lysis buffer (Input), Western blotting and ELISA were performed.
[0259] 3. Protein extraction and sample preparation
[0260] 1) Extraction of protein from cell culture supernatant: Place the sample in a centrifuge and centrifuge at 13,000 rpm for 5 min to remove dead cells and impurities; transfer the supernatant to a new EP tube, add 500 μL methanol and 125 μL chloroform, vortex to mix well, and centrifuge at 13,000 rpm for 5 min; remove the upper liquid, at which point the middle layer is the protein solution, add 500 μL methanol, vortex to mix well, and centrifuge at 13,000 rpm for 5 min; the protein precipitates at the bottom of the EP tube, remove the supernatant, let stand for 10 min to evaporate the methanol completely, add 60 μL 1×SDS loading buffer, dissolve thoroughly, and denature at 100℃ for 10 min.
[0261] 2) Extraction of cell proteins: Add 120 μL of cell lysis buffer to the cells after removing the cell supernatant. After fully lysing the cells, add 5×SDS loading buffer and denature at 100℃ for 10 min.
[0262] 4. Western Blot Detection
[0263] Western blotting (WB) was performed using a 4-12% protein gel. The protein electrophoresis conditions were 70-80V for 20-30 minutes, and the separating gel conditions were 130-160V for 60-90 minutes. The PVDF membrane was pre-activated by soaking it in methanol for 5-10 minutes. The filter paper and sponge were pre-soaked in transfer buffer. After electrophoresis, the protein gel was soaked in transfer buffer for 5-10 minutes. The membrane was transferred using a sandwich structure of sponge-filter paper-gel-membrane-filter paper-sponge at 250mA for 90 minutes. The membrane was blocked with 5% skim milk for 1 hour. The primary antibody was diluted with 5% BSA according to the antibody dilution ratio, and incubated overnight at 4°C. The next day, the membrane was washed three times with 1×TBST, 5 minutes apart. The secondary antibody was diluted with 1×TBST according to the antibody dilution ratio, incubated for 1 hour, and washed three times with 1×TBST, 5 minutes apart. After washing, the membrane was exposed to ECL ultrasensitive exposure buffer.
[0264] The inhibitory effect of the compound on the NLRP3 inflammasome pathway was evaluated by measuring the amount of IL-1β secreted by BMDM cells stimulated with LPS+Nigericin after compound treatment. ImageJ was used to calculate the gray values of the IL-1β band in the culture supernatant and the internal reference protein GAPDH band in the cell lysate, and their ratio was determined. The gray values of the control group (DMSO treatment group) were normalized, and the IC50 was calculated using GraphPad Prism. 50 The experimental results are detailed in the table below.
