Abstract
Description
A NEK7 inhibitor, pharmaceutical composition and use thereof Technical Field
[0001] The present invention belongs to the field of biopharmaceuticals and specifically relates to NEK7 kinase inhibitor compounds represented by general formula (I), pharmaceutically acceptable salts, esters, stereoisomers, tautomers, and pharmaceutical compositions and formulations containing the same, as well as their uses. The compounds of the present invention selectively inhibit the NEK7 family of tyrosine kinases and can be used to treat diseases mediated by abnormal NEK7 kinase expression. Background Art
[0002] Inflammation is a protective immune response initiated by the host's innate immune system in response to stimuli such as allergens and pathogenic organisms. The innate immune response is tightly regulated by the host. Importantly, inflammation can lead to persistent infection, while excessive inflammation can cause autoimmune diseases. Inflammasomes are cytoplasmic supramolecular protein complexes whose activation activates cytokines such as IL-1β and IL-18, mediated by caspase 1, and induces inflammation and pyroptosis, playing a central role in innate immunity and inflammation. To date, four types of inflammasomes have been discovered: NLRP1, NLRP3, NLRC4, and AIM2. NLRP3 is a key downstream effector of signals triggering inflammatory responses and has been implicated in driving the onset and progression of many chronic inflammatory diseases, neurodegenerative disorders, and cardiovascular diseases. NLRP3 activation triggers the release of proinflammatory cytokines IL-1β and IL-18 and induces a lytic cell death process known as pyroptosis. Blocking the inflammasome-mediated inflammatory response can help treat many diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, atopic dermatitis, ulcerative colitis, Crohn's disease, cancer, osteoarthritis, gout, etc.
[0003] NEK7 (NIMA-related kinase 7) protein kinase is the smallest of a family of 11 mammalian NEKs (NEK1-NEK11). It is expressed in numerous tissues and has been shown to be crucial in mitotic regulation and NLRP3 inflammasome activation. Inhibition of NLRP3 signaling by NEK7 prevents NLRP3 inflammasome formation, thereby inhibiting IL-1β and IL-18 production and pore-forming gasdermin D cleavage. Pyroptosis is associated with numerous inflammatory diseases, and thus, inhibitors of NLRP3 inflammasome activation that block the NLRP3-NEK7 interaction may have therapeutic or preventive activity in conditions such as chronic inflammation, neurodegenerative diseases, and cardiovascular disease.
[0004] A number of inhibitors have been widely used to interfere with effector signaling pathways involving IL-1β or IL-18 without eliminating inflammatory responses. Inhibitors that block NLRP3 inflammasome activation through the NLRP3-NEK7 interaction may have therapeutic or preventive activity in several human diseases, such as type 2 diabetes, atherosclerosis, gout, and neurodegenerative diseases.
[0005] Therefore, it is necessary to develop inhibitors that selectively target NEK7 for the treatment or prevention of several inflammatory pathological diseases regulated by the NLRP3 inflammasome (Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, atopic dermatitis, ulcerative colitis, Crohn's disease, cancer, osteoarthritis, gout, etc.).

[0053] In some embodiments, pharmaceutically acceptable salts include quaternary ammonium salts, such as quaternary ammonium alkyl halide salts (eg, methyl bromide).
[0054] The terms "antagonist" and "inhibitor" are used interchangeably, and they refer to compounds that have the ability to inhibit the biological function of a target protein, whether by inhibiting the activity or expression of a protein (e.g., NLRP3 inflammasome or NEK7) or by inhibiting the association of NLRP3 inflammasome with NEK7. Thus, the terms "antagonist" and "inhibitor" are defined in the context of the biological action of the target protein. Although preferred antagonists herein particularly interact with (e.g., bind to) the target, compounds that inhibit the biological activity of the target protein by interacting with other members of the signal transduction pathway of which the target protein is a member are also particularly included in this definition. The preferred biological activity inhibited by the antagonist is associated with the development, growth, or spread of a tumor.
[0055] As used herein, the term "agonist" refers to a compound that has the ability to induce or enhance the biological function of a target protein, whether or not by inhibiting the activity or expression of the target protein. Thus, the term "agonist" is defined in the context of the biological action of the target polypeptide. Although preferred agonists herein particularly interact with (e.g., bind to) the target, compounds that induce or enhance the biological activity of the target polypeptide by interacting with other members of the signal transduction pathway of which the target polypeptide is a member are also particularly included in this definition.
[0056] "Signal transduction" is the process by which stimulatory or inhibitory signals are transmitted into and within cells to elicit intracellular responses.
[0057] The term "selective inhibition" or "selectively inhibits" refers to the ability of a biologically active agent, through direct or indirect interaction with the target, such that the agent preferentially reduces target signaling activity compared to off-target signaling activity.
[0058] "Subject" refers to an animal, such as a mammal, such as a human. The methods described herein can be used for human therapy and veterinary applications. In some embodiments, the subject is a mammal, and in some embodiments, the subject is a human.
[0059] "Mammal" includes humans and livestock animals, such as laboratory animals and household pets (e.g., cats, dogs, pigs, cows, sheep, goats, horses, rabbits), as well as non-livestock animals, such as wild animals, etc.
[0060] "Prodrug" is intended to mean a compound (e.g., a compound of structure (I)) that can be converted into a bioactive compound as described herein under physiological conditions or by solvolysis. Thus, the term "prodrug" refers to a precursor of a pharmaceutically acceptable bioactive compound. In some aspects, the prodrug is inert when applied to a subject, but is converted into an active compound in vivo, such as by hydrolysis. Prodrug compounds often provide advantages of solubility, tissue compatibility, or delayed release in mammalian organisms. The term "prodrug" also means any covalently bonded carrier that releases the active compound in vivo when such prodrugs are applied to mammalian individuals. Prodrugs of active compounds as described herein are typically prepared by modifying the functional groups present in the active compound in such a way that the modification is cleaved into the parent active compound in conventional operations or in vivo. Prodrugs include compounds wherein a hydroxyl, amino, or thiol group is connected to any group, and when the prodrug of the active compound is applied to a mammalian individual, it is cleaved to form free hydroxyl, free amino, or free thiol groups. Examples of prodrugs include, but are not limited to, acetic acid, formic acid, and benzoic acid derivatives of a hydroxy functional group or acetamide, formamide, and benzamide derivatives of an amine functional group in the active compound, and the like.
[0061] The term "in vivo" refers to events that occur within the body of an individual.
[0062] The embodiments disclosed herein are also meant to encompass all pharmaceutically acceptable compounds of structure (I).
[0063] Certain embodiments are also intended to include in vivo metabolites of the disclosed compounds. Such products can be produced, for example, by oxidation, reduction, hydrolysis, amidation, esterification, etc. of the administered compound, primarily due to enzymatic processes. Thus, embodiments include compounds produced by methods comprising administering a compound of the disclosure to a mammal for a period of time sufficient to produce its metabolites. Such products are typically identified by administering a detectable dose of a radiolabeled compound of the disclosure to an animal (e.g., rat, mouse, guinea pig, monkey) or to a human, allowing sufficient time for metabolism, and isolating its conversion products from urine, blood, or other biological samples.
[0064] "Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
[0065] Typically, crystallization produces solvates of the compounds disclosed herein. As used herein, the term "solvate" refers to an aggregate comprising one or more molecules of the compounds of the disclosure and one or more solvent molecules. In some embodiments, the solvent is water, in which case the solvate is a hydrate. Alternatively, in other embodiments, the solvent is an organic solvent. Thus, the compounds of the disclosure may exist as hydrates, including monohydrates, dihydrates, hemihydrates, sesquihydrates, trihydrates, tetrahydrates, and the like, as well as the corresponding solvated forms. The compounds of the disclosure may be true solvates, while in other cases, the compounds of the disclosure retain only adventitious water or are a mixture of water plus some adventitious solvent.
[0066] "Optional" or "optionally" means that the subsequently described event or circumstances may or may not occur, and that the description includes instances where the event or circumstances occur and instances where it does not. For example, "optionally substituted aryl" means that the aryl group may or may not be substituted, and that the description includes both substituted aryl groups and aryl groups without substituents.
[0067] "Pharmaceutical composition" refers to a preparation of a compound of the present disclosure and a medium generally accepted in the art for delivering the compound of the present disclosure to a mammal (e.g., a human). Such a medium includes all pharmaceutically acceptable carriers, diluents, or excipients therefor.
[0068] "Pharmaceutically acceptable carrier, diluent or excipient" includes, but is not limited to, any adjuvant, carrier, excipient, glidant, sweetener, diluent, preservative, dye / colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent or emulsifier.
[0069] "Stereoisomers" refer to compounds composed of the same atoms bonded to the same bonds but having different three-dimensional structures that are not interchangeable. The present disclosure contemplates various stereoisomers and mixtures thereof and includes "enantiomers," which refer to two stereoisomers whose molecules are non-superimposable mirror images of each other.
[0070] The compounds of the present disclosure (i.e., compounds of structure (I)) or pharmaceutically acceptable salts thereof may contain one or more centers of geometric asymmetry and may therefore give rise to stereoisomers, such as enantiomers, diastereomers and other stereoisomeric forms, which are defined in terms of absolute stereochemistry as (R)- or (S)-, or (D)- or (L)- of an amino acid. Embodiments therefore include all such possible isomers, as well as racemic and optically pure forms thereof. Optional active (+) and (-), (R)- and (S)- or (D)- and (L)- isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques such as chromatography and fractional crystallization. Conventional techniques for preparing / isolating individual enantiomers include chiral synthesis from suitable optically pure precursors or resolution of the racemate (or racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC). When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are intended to be included.
[0071] Embodiments of the present disclosure include all forms and conformationally restricted states of rotational isomers of the compounds of the present invention. Also included are atropisomers, which are stereoisomers arising from hindered rotation about a single bond, where energy differences due to steric strain or other contributing factors create a rotational barrier high enough to allow separation of the individual conformers. As an example, certain compounds of the present disclosure may exist as a mixture of atropisomers, or may be purified or enriched to allow the presence of a single atropisomer.
[0072] In some embodiments, the compound of structure (I) is a mixture of enantiomers or diastereomers. In other embodiments, the compound of structure (I) is substantially a single enantiomer or diastereomer.
[0073] "Tautomer" refers to a proton shift from one atom of a molecule to another atom of the same molecule. The embodiments therefore include tautomers of the disclosed compounds.
[0074] "NEK7-NLRP3-mediated disorders" refers to diseases or pathological processes caused by the interaction between NEK7 and NLRP3, including autoimmune diseases, inflammatory disorders, cardiovascular diseases, neurodegenerative disorders, bacterial and viral infections, allergies, asthma, pancreatitis, multiple organ failure, kidney disease, platelet aggregation, cancer, transplantation, sperm motility, red blood cell deficiency, transplant rejection, lung injury, respiratory diseases and ischemic conditions, etc.; in particular, including type 2 diabetes, atherosclerosis, Alzheimer's disease, aging, fatty liver, metabolic syndrome, asthma, psoriasis, obesity, acute and chronic tissue damage caused by infection, gout, arthritis, macular degeneration, enteritis, hepatitis, peritonitis, silicosis, UV-induced skin sunburn, contact hypersensitivity, sepsis, cancer, neurodegenerative diseases, multiple sclerosis and Mueller-Willi syndrome, etc. Conditions mediated by the NEK7-NLRP3 interaction include rheumatoid arthritis, psoriatic arthritis, osteoarthritis, systemic lupus erythematosus, lupus nephritis, ankylosing spondylitis, osteoporosis, systemic sclerosis, multiple sclerosis, psoriasis, type I diabetes, type II diabetes, inflammatory bowel disease (Crohn's disease and ulcerative colitis), hyperimmunoglobulinemia D and periodic fever syndromes, cryptopyrin-associated periodic syndromes, Schnitzler syndrome, systemic juvenile idiopathic arthritis, adult-onset Still's disease, gout, pseudogout, SAPHO syndrome, Castleman's disease, sepsis, stroke, atherosclerosis, celiac disease, DIRA (deficiency of IL-1 receptor antagonist), Alzheimer's disease, Parkinson's disease, and cancer.

[1017] Experimental equipment: HEKA EPC 10 patch clamp amplifier.
[1018] Experimental Methods: This experiment uses manual patch clamp technology to detect the blocking effect of compounds on the current of HEK-293 cell lines stably expressing hERG channels, and evaluates the risk of compound inhibition of cardiac hERG potassium channels by fitting the concentration-effect relationship.
[1019] Experimental Procedure: Patch clamping involves first pulling a recording electrode from a glass capillary using a microelectrode puller. The electrode, filled with intracellular fluid, is then inserted into a microelectrode holder. Under an inverted microscope, the microelectrode manipulator is used to immerse the electrode in extracellular fluid and record the electrode resistance (Rpip). The electrode is then gently brought into contact with the cell surface, and negative pressure is applied to form a GΩ seal. Fast capacitance compensation is then performed, and negative pressure is continued to rupture the cell membrane, establishing whole-cell recording mode. Finally, slow capacitance compensation is performed, and experimental parameters such as series resistance (Rs) are recorded. No leakage compensation is applied. Drug administration is initiated after the whole-cell hERG current has stabilized. Each drug concentration is tested after approximately 5 minutes of exposure (or until the current stabilizes). Multiple concentrations of each test compound are tested. A coverslip containing cells is placed in the recording bath under an inverted microscope. A blank control solution and the test compound working solution are gravity-flown through the recording bath, sequentially applying the solution from low to high concentrations. A peristaltic pump is used for fluid exchange during recording. The current measured in each cell in the presence of compound-free external solution served as its own control. Each concentration was tested in triplicate. All electrophysiological experiments were performed at room temperature.
[1020] Experimental data analysis method: First, normalize the current after each drug concentration and the blank control current Then calculate the inhibition rate corresponding to each drug concentration The mean (Mean), standard deviation (SD) and standard error (SE) of the inhibition rate at each concentration were calculated;
[1021] Among them, Peak tail current compound Peak tail current control It represents the peak-to-tail current of blank control.
