[0002] This application claims priority to AU2018904241 and AU2018904242 (each filed on 7 November 2018). The entire contents of each of AU2018904241 and AU2018904242 are incorporated herein by reference. Technical Field
[0003] The present invention provides imidazole-based compounds that have potential in treating respiratory diseases such as asthma and related disorders, acute and chronic inflammatory disorders, fibrotic diseases or disorders in which fibrosis contributes to the pathology of the disorder. Background Art
[0004] Asthma is a syndrome that encompasses a variety of different types of illness that vary in severity, causes, and triggers. Common features of the asthma syndrome are reversible airway obstruction, airway hyperresponsiveness, and airway inflammation, most notably the infiltration of the airway wall by eosinophils and T lymphocytes in addition to mast cell activation.
[0005] Current asthma medications include short-acting and long-acting β2-adrenergic receptor selective agonists (SABA and LABA) and inhaled corticosteroids (ICS). Ultra-LABA is now also available. Short-acting and long-acting muscarinic receptor antagonists (SAMA and LAMA) are often used in combination with other bronchodilators and anti-inflammatory drugs (especially ICS) for some patients. Leukotriene receptor antagonists (LTRA) can also be added to different treatment regimens. Recently, mepolizumab, a monoclonal antibody that neutralizes the chemoattractant of eosinophils (interleukin-5), has been shown to have benefits beyond the combination of ICS and LABA in specific patients. However, especially for severe asthma, patients still have symptoms and have periodic exacerbations of the disease (called exacerbations). There is a considerable unmet need in the pharmacological treatment of severe asthma. In most cases, these asthma exacerbations are thought to be caused by respiratory viral infections of the lower respiratory tract. Viruses that cause these exacerbations include respiratory syncytial virus, influenza virus, and rhinovirus, which infect respiratory epithelial cells. Epithelial cells in asthmatic individuals are thought to be particularly susceptible to this infection and have been implicated in an exacerbated inflammatory response.
[0006] Studies have shown that TGF-β can impair the effectiveness of ICS. In addition, the inventors have demonstrated that viral infection of airway epithelial cells impairs ICS activity by inducing TGF-β activity. Drug targeting of TGF-β carries the risk of autoimmunity and mitral valve defects. The inventors unexpectedly identified casein kinase 1δ / ε as a mediator of TGF-β-induced ICS insensitivity using compound PF670462 (WO2016 / 149756) and demonstrated the use of this agent in reversing steroid insensitivity.
[0007] This would be beneficial in developing alternative compounds useful in preventing or treating one or more respiratory diseases, acute and chronic inflammatory conditions, and fibrotic diseases or conditions where fibrosis contributes to the pathology of the condition.

[0197] The composition may further include one or more components suitable for improving the stability or effectiveness of the applied preparation, such as stabilizers, suspending agents, emulsifiers, viscosity modifiers, gelling agents, preservatives, antioxidants, transdermal enhancers, humectants and sustained release materials. Examples of such components are described in Martindale-The Extra Pharmacopoeia (Pharmaceutical Press, London, 1993) and Martin (ed.), Remington's Pharmaceutical Sciences. The preparation may include microcapsules, such as hydroxymethylcellulose or gelatin microcapsules, liposomes, albumin microspheres, microemulsions, nanoparticles or nanocapsules.
[0198] Topical preparations can be prepared in a variety of physical forms, including, for example, solids, pastes, creams, foams, lotions, gels, powders, aqueous liquids, emulsions, sprays and skin patches. The physical appearance and viscosity of such forms can be controlled by the presence and amount of one or more emulsifiers and one or more viscosity modifiers present in the preparation. Solids are usually hard and non-pourable, and are usually formulated into strips or rods, or are in particle form. Solids can be opaque or transparent, and can optionally include solvents, emulsifiers, humectants, emollients, spices, dyes / colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product. Creams and lotions are usually similar to each other, mainly in that their viscosities are different. Creams and lotions can all be opaque, translucent or transparent, and usually include emulsifiers, solvents and viscosity modifiers and humectants, emollients, spices, dyes / colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product. Gels with a range of viscosities can be prepared, from thick or high viscosity to rare or low viscosity. These formulations, like lotions and creams, may also contain solvents, emulsifiers, moisturizers, emollients, fragrances, dyes / colorants, preservatives, and other active ingredients that increase or enhance the efficacy of the final product. Liquids are thinner than creams, lotions, or gels and typically do not contain emulsifiers. Liquid topical products typically contain solvents, emulsifiers, moisturizers, emollients, fragrances, dyes / colorants, preservatives, and other active ingredients that increase or enhance the efficacy of the final product.
[0199] Emulsifiers for topical preparations include but are not limited to ionic emulsifiers, cetearyl alcohol, nonionic emulsifiers such as polyoxyethylene oleyl ether, PEG-40 stearate, ceteareth-12, ceteareth-20, ceteareth-30, ceteareth alcohol, PEG-100 stearate and glyceryl stearate. Suitable viscosity modifiers include but are not limited to protective colloids or nonionic glues, such as hydroxyethylcellulose, xanthan gum, magnesium aluminum silicate, silicon dioxide, microcrystalline wax, beeswax, paraffin and cetyl alcohol hexadecanoate. Gel compositions can be formed by adding gelling agents such as chitosan, methylcellulose, ethylcellulose, polyvinyl alcohol, polyquaternium salt, hydroxyethylcellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, carbomer or ammoniated glycyrrhizic acid. Suitable surfactants include but are not limited to nonionic, amphoteric, ionic and anionic surfactants. For example, one or more of dimethicone copolyol, polysorbate 20, polysorbate 40, polysorbate 60, polysorbate 80, lauramide DEA, cocamide DEA and cocamide MEA, oleyl betaine, cocamidopropyl phosphatidyl PG-dimonium chloride, and ammonium laureth sulfate may be used in topical formulations.
[0200] Preservatives include, but are not limited to, antimicrobial agents, and physical stabilizers and antioxidants, such as methylparaben, propylparaben, sorbic acid, benzoic acid and formaldehyde, and physical stabilizers and antioxidants such as vitamin E, sodium ascorbate / ascorbic acid and propyl gallate. Suitable moisturizers include, but are not limited to, lactic acid and other hydroxy acids and their salts, glycerol, propylene glycol and butylene glycol. Suitable lubricants include lanolin alcohol, lanolin, lanolin derivatives, cholesterol, petrolatum, isostearyl neopentanoate and mineral oil. Suitable spices and pigments include, but are not limited to, FD&C Red No. 40 and FD&C Yellow No. 5. Other suitable additional ingredients that may be included in topical preparations include, but are not limited to, abrasives, absorbents, anti-caking agents, defoamers, antistatic agents, astringents (e.g., witch hazel), alcohols and herbal extracts (e.g., chamomile extracts), binders / excipients, buffers, chelating agents, film formers, conditioners, propellants, opacifiers, pH regulators and protective agents.
[0201] Typical delivery modes of topical compositions include application with fingers, application with a physical applicator (e.g., cloth, tissue, cotton swab, stick or brush), spraying (including mist, aerosol or foam spray), dropper application, sprinkling, soaking and rinsing. Controlled release carriers may also be used, and the composition may be formulated for transdermal administration (e.g., as a transdermal patch).
[0202] The pharmaceutical composition can be formulated into a sustained release formulation, such as a capsule that produces a slow release of the regulator after administration. Such formulations can be prepared using known techniques generally, and can be administered, for example, by oral, rectal or subcutaneous implantation or by implantation at a desired target site. The carrier used in such formulations is biocompatible and can also be biodegradable. Preferably, the formulation provides a relatively constant level of regulator release. The amount of regulator contained in the sustained release formulation depends on, for example, the implantation site, the rate of release and the expected duration, and the nature of the disease to be treated or prevented.
[0203] The pharmaceutical composition can be formulated into an inhalation formulation, including sprays, mists or aerosols. For example, for respiratory administration. This may be particularly preferred for the treatment of respiratory diseases, the treatment of fibrotic airways or lung conditions as described herein. Inhalation formulations can be used for the upper respiratory tract (including the nasal cavity, pharynx and larynx) and the lower respiratory tract (including the trachea, bronchi and lungs). For inhalation formulations, the compositions or combinations provided herein can be delivered by any inhalation method known to those skilled in the art. Such inhalation methods and devices include, but are not limited to, metered dose inhalers with propellants such as HFA or physiologically and environmentally acceptable propellants. Other suitable devices are breath-operated inhalers, multi-dose dry powder inhalers and aerosol nebulizers. Aerosol formulations used for the subject method generally include propellants, surfactants and cosolvents, and can be filled into conventional aerosol containers closed by suitable metering valves. Depending on the application to the upper respiratory tract (including the nasal cavity, pharynx and larynx) or the lower respiratory tract (including the trachea, bronchi and lungs), different devices and excipients can be used, and can be determined by those skilled in the art. Furthermore, methods of micronization and nanoparticle formation for preparing the compounds described herein for use in inhalers such as dry powder inhalers are also known to those skilled in the art.
[0204] Inhalation compositions may include liquid or powdered compositions comprising active ingredients suitable for atomization and intrabronchial use, or aerosol compositions for administration of metered doses distributed by an aerosol unit. Suitable liquid compositions include active ingredients in aqueous, pharmaceutically acceptable inhalation solvents (such as isotonic saline or antibacterial water). The solution is administered by means of a pump or extrusion-actuated atomizing spray dispenser or by any other conventional means to cause or cause the necessary dose of the liquid composition to be inhaled into the patient's lungs. Suitable formulations for administration (wherein, the carrier is a liquid) such as nasal sprays or nasal drops include aqueous or oily solutions of active ingredients. Examples of inhaled drug delivery devices are described in Ibraim et al., Medical Devices: Evidence and Research 2015: 8 131–139, and are contemplated for use in the present invention.
[0205] In another aspect, provided is a method for treating or preventing a respiratory disease in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of a compound of formula (I) or a salt, solvate, N-oxide, tautomer, stereoisomer, polymorph and / or prodrug thereof, thereby treating or preventing the respiratory disease in the subject.
[0206] Further provided is a compound of formula (I) or a salt, solvate, N-oxide, tautomer, stereoisomer, polymorph and / or prodrug thereof for use in treating or preventing a respiratory disease in a subject in need thereof.
[0207] Also described is the use of a compound of formula (I) or a salt, solvate, N-oxide, tautomer, stereoisomer, polymorph and / or prodrug thereof in the preparation of a medicament for treating or preventing a respiratory disease in a subject in need thereof.
[0208] As used herein, "preventing" or "preventing" is intended to mean at least reducing the likelihood of acquiring the risk (or susceptibility) of a disease or condition (i.e., preventing the development of at least one clinical symptom of the disease in a patient who may be exposed to or susceptible to the disease but has not yet experienced or shown symptoms of the disease). Biological and physiological parameters for identifying such patients are provided herein and are also well known to physicians.
[0209] The term "treatment" or "treating" a subject includes applying or administering a compound of the invention to a subject (or to a cell or tissue from a subject) for the purpose of delaying, slowing, stabilizing, curing, healing, alleviating, relieving, altering, remedying, alleviating, worsening, improving, ameliorging, or affecting a disease or condition, a symptom of a disease or condition, or a risk (or susceptibility) for a disease or condition. The term "treat" refers to any indication of success in the treatment or improvement of an injury, pathology, or condition, including any objective or subjective parameter, such as alleviation; remission; reducing the rate of worsening; reducing the severity of a disease; stabilizing, alleviating symptoms, or making an injury, pathology, or condition more tolerable to a subject; slowing the rate of degeneration or decline; making the endpoint of degeneration less debilitating; or improving the physical or mental health of a subject.
[0210] As used herein, the term "antagonize" means "reduce" or "decrease". A sufficient period of time may be one week, or 1 week to 1 month, or 1 month to 2 months, or 2 months or longer. For chronic conditions, the compounds of the invention may be advantageously administered during the life span.
[0211] The term "breathing" refers to the process of taking oxygen into the body and expelling carbon dioxide through the body system including the nose, throat, larynx, trachea, bronchi, and lungs.
[0212] The term "respiratory disease" or "respiratory disorder" refers to any of several ailments that may involve inflammation and / or tissue remodeling affecting components of the respiratory system, including the upper respiratory tract (including the nasal cavity, pharynx, and larynx) and the lower respiratory tract (including the trachea, bronchi, and lungs). These ailments include pulmonary fibrosis (interstitial lung disease), sinusitis, influenza, sarcoidosis, bronchial cancer (including but not limited to non-small cell lung cancer and small cell lung cancer, and lung metastases from tumors of other organs), silicosis, pneumoconiosis, acute lung injury, ventilation-induced lung injury, congenital emphysema, bronchopulmonary dysplasia, bronchiectasis, atelectasis, nasal polyps, asbestosis, mesothelioma, pulmonary eosinophilia, diffuse pulmonary hemorrhagic syndrome, bronchiolitis obliterans, pulmonary alveolar proteinosis, collagen and vascular diseases affecting the lungs, and cough. Preferably, the respiratory disease is an obstructive airway disease, such afflictions include: asthmatic conditions including hay fever, allergen-induced asthma, exercise-induced asthma, pollution-induced asthma, cold-induced asthma, stress-induced asthma, viral-induced asthma, obesity-related asthma, occupational asthma, storm-induced asthma, asthma-COPD overlap syndrome (ACOS); chronic obstructive pulmonary disease including chronic bronchitis with normal airflow, chronic bronchitis with airway obstruction (chronic obstructive bronchitis), emphysema, asthmatic bronchitis; and bullous diseases; and other lung diseases involving inflammation including cystic fibrosis, pigeon fancier's disease, disease), farmer's lung, acute respiratory distress syndrome, fungal pneumonia, viral pneumonia, bacterial pneumonia, mixed or unknown etiology, inspiration or aspiration injury, fat embolism in the lung, acidotic inflammation of the lung, acute pulmonary edema, acute mountain sickness, post-cardiac surgery, acute pulmonary hypertension, persistent pulmonary hypertension of the newborn, perinatal aspiration syndrome, hyaline membrane disease, acute pulmonary thromboembolism, heparin-protamine reaction, sepsis, status asthmaticus, and hypoxia. Inflammation in the upper and lower respiratory tracts may be associated with or caused by viral infections or allergens. It is expected that the anti-inflammatory activity of the compounds when administered alone or in combination with glucocorticoids will make them particularly suitable for treating these diseases or conditions.
[0213] Respiratory diseases or conditions may be associated with or caused by allergens, such as dust mites. Respiratory diseases or conditions may be the result of allergen-induced inflammation. The present invention is particularly applicable to allergic diseases of the airways or lungs and exacerbations of the disease, such as exacerbations caused by viral infections, such as RSV infections.
[0214] Symptoms of respiratory diseases can include coughing, producing excessive sputum, dyspnea or chest tightness with audible wheezing. Exercise capacity may be quite limited. In asthma, FEV1.0 (forced expiratory volume in one second) accounts for a percentage of the prediction of the nomogram based on weight, height and age, which may decrease with the peak expiratory flow rate in forced exhalation. In COPD, FEV1.0 is the ratio of forced vital capacity (FVC) that is usually reduced to less than 0.7. In IPF, FVC gradually decreases. The impact of each of these conditions can also be measured by the number of days of absence from work / school, sleep disorders, the need for bronchodilators, and the need for glucocorticoids (including oral glucocorticoids). Further measurements of the impact of these conditions include validated health-related quality of life measurements. Medical imaging procedures including but not limited to X-rays, high-resolution computed tomography, magnetic resonance imaging, positron emission tomography, ultrasound, optical coherence tomography and fluoroscopy can also be used to evaluate disease and treatment response.
[0215] The presence, amelioration, treatment or prevention of respiratory disease can be measured by any clinical or biochemically relevant method of the subject or its biopsy. For example, the parameters measured can be the presence or degree of lung function, signs and symptoms of obstruction; exercise tolerance; nighttime awakenings; number of days missed from school or work; use of bronchodilators; ICS dosage; use of oral GCs; need for other medications; need for medical treatment; hospitalization.
[0216] As used herein, the term "asthma" refers to a respiratory disorder characterized by paroxysmal dyspnea caused by any one or combination of the following three main factors: 1) bronchospasm (i.e., variable and reversible airway obstruction due to contraction of airway muscles), 2) inflammation of the airway lining, and 3) bronchial hyperresponsiveness resulting in excess mucus in the airways, which can be triggered by exposure to allergens or allergen combinations (i.e., dust mites and molds), viral or bacterial infections (i.e., common cold viruses), environmental pollutants (i.e., chemical fumes or smoke), physical exertion (i.e., during exercise), stress, or inhalation of cold air. As used herein, the term "asthmatic condition" refers to the characteristics of an individual experiencing an asthma attack when exposed to any one or more asthma triggers for the individual. The characteristics of an individual can be experiencing, for example, allergen-induced asthma, exercise-induced asthma, pollution-induced asthma, virus-induced asthma, or cold-induced asthma.
[0217] The efficacy of asthma treatment can be measured by methods well known in the art, such as increase in lung function (spirometry), reduction in asthma exacerbations, increase in morning peak expiratory flow rate, reduction in rescue medication use, reduction in daytime and nighttime asthma symptoms, increase in asthma-free days, increase in time to asthma exacerbation, and increase in forced expiratory volume in one second (FEV1.0).
[0218] The terms "chronic obstructive pulmonary disease" and "COPD" used interchangeably herein refer to a chronic condition or combination of conditions characterized by a decrease in maximum expiratory flow and a slow forced emptying of the lungs, which does not change significantly over several months and is irreversible or only minimally reversible using conventional bronchodilators. Most commonly, COPD is a combination of chronic bronchitis, i.e., cough and sputum for more than three months for about two consecutive years, and emphysema, i.e., alveolar damage. However, COPD may involve chronic bronchitis with normal airflow, chronic bronchitis with airway obstruction (chronic obstructive bronchitis), emphysema, asthmatic bronchitis, and bullous diseases, and combinations thereof. Chronic obstructive pulmonary disease is a condition usually, but not exclusively, caused by chronic lung damage induced by exposure to tobacco smoke. Other harmful airborne pollutants such as indoor cooking exhaust and automobile exhaust may cause COPD or increase the risk of COPD in the long term, as does aging.
[0219] The phrase "a condition of the airways or lungs involving fibrosis" or "a condition of the airways or lungs having a fibrotic component" includes any disease or condition in which excess fibrous connective tissue (fibrosis) forms or develops in the airways or lungs, resulting in the development of scar (fibrotic) tissue. This includes interstitial lung diseases such as pulmonary fibrosis, lung fibrosis, or idiopathic pulmonary fibrosis (IPF). More precisely, pulmonary fibrosis is a chronic disease that causes swelling and scarring of the alveoli and interstitial tissue of the lungs. Scar tissue replaces healthy tissue and causes inflammation. This damage to the lung tissue leads to hardening of the lungs, which then makes breathing increasingly difficult. Pulmonary fibrosis can be caused by radiation damage or exposure to therapeutic agents such as bleomycin.
[0220] "Idiopathic pulmonary fibrosis (IPF)" is a specific manifestation of idiopathic interstitial pneumonia (IIP), which is a type of interstitial lung disease. Interstitial lung disease, also known as diffuse parenchymal lung disease (DPLD), refers to a type of lung disease that affects the interstitium. Under a microscope, lung tissue from IPF patients shows a set of characteristics of histological features known as usual interstitial pneumonia (UIP). UIP is therefore a pathological manifestation of IPF.
[0221] The presence, improvement, treatment or prevention of airway or lung disorders related to fibrosis, particularly pulmonary fibrosis / pulmonary fibrosis or idiopathic pulmonary fibrosis can be carried out by any clinical or biochemical correlation method of the experimenter or its biopsy. For example, the rate of decline of FVC or the appearance of high-resolution computed tomography images of the lung can be used for diagnosing IPF. In addition, the parameter measured can be the presence or degree of fibrosis, the content of collagen, fibronectin or another extracellular matrix protein, the proliferation rate of any extracellular matrix component in the cell or cell, or the transdifferentiation of cells into myofibroblasts.
[0222] In one embodiment, the respiratory disease is selected from asthma, chronic obstructive pulmonary disease, interstitial lung disease (e.g., idiopathic pulmonary fibrosis) and other disorders associated with tissue remodeling, primary or secondary lung tumors, hay fever, chronic and acute sinusitis, and chronic and acute respiratory viral, fungal and bacterial infections.
[0223] In one embodiment, the improvement of respiratory function can be selected from the reduction of lung contraction level, the reduction of respiratory system elastic stiffness, and / or the increase of the ease with which the respiratory system can be stretched. Preferably, the improvement is selected from the reduction of lung contraction level and the reduction of respiratory system elastic stiffness. On the other hand, a composition is provided, which comprises a compound according to formula (I) or its salt, solvate, N-oxide, tautomer, stereoisomer, polymorph and / or prodrug, and a pharmaceutically acceptable excipient.
[0224] The therapeutically effective amount of the preparation depends on the severity of the specific respiratory disease indication (e.g., severe chronic asthma), the patient's clinical history and reaction, and the judgment of the attending physician. The preparation can be applied to the patient once or through a series of treatments. The initial candidate dose can be applied to the patient, and the appropriate dosage and treatment regimen can be established by monitoring the progress of the patient using conventional techniques known to those of ordinary skill in the art. Preferably, the therapeutically effective concentration of the active compound will be in the range of 0.1nM to 100μM. More preferably, the range is 0.1μM to 10μM. However, it should be understood that delivery by inhalation may cause the cells in the airway to be exposed to a concentration exceeding the above concentration for a period of time in a short time, while the drug is diluted in the airway surface fluid and also absorbed from the airway and lung surface.
[0225] In one aspect, the treatment methods of the present invention further include administering a concomitant medication for the target disease indication. For example, concomitant asthma medications (for both chronic and acute) that can be used with the methods of the present invention include, but are not limited to: inhaled and oral steroids (e.g., beclomethasone, budesonide, flunisolide, fluticasone, triamcinolone, mometasone); systemic corticosteroids (e.g., methylprednisolone, prednisolone, prednisone, dexamethasone, and deflazacort); inhaled or oral β2-adrenergic receptor agonists (e.g., salmeterol, formoterol, bitolterol, pirbuterol, vilanterol, terbutaline, bambuterol, and salbutamol); cromoglycine and nedocrolate; antiallergic ophthalmic drugs (e.g., dexamethasone); agents that modulate the production and action of transforming growth factor-β, including pirfenidone and nintedanib; methylxanthines and other phosphodiesterase inhibitors (e.g., theophylline and mepyramine-theophyllineacetate, roflumilast); leukotriene modifiers (e.g., zafirlukast, zileuton, montekulast, and pranlukast); anticholinergics (e.g., ipratropium bromide); other therapeutic antibodies in any form (e.g., antibodies to interleukin 5 such as mepolizumab, or antibodies to IgE such as omalizumab, those in monoclonal form, Fab, scFV, multivalent compositions, xenoantibodies, etc.), natural or engineered antibody mimetics (e.g., chemical contaminant mimetic antibodies (anticalins)) or natural, engineered or synthetic peptides; thromboxane A2 synthetase inhibitors; thromboxane prostanoid receptor antagonists; other eicosanoid modulators (e.g., alprostadil relative to PGE1, dinoprostone relative to PGE2, epoprostenol relative to prostacyclin and PGI2 analogs (e.g., PG12 beraprost), serotonin, phosphodiesterase 4 isozyme inhibitors, thromboxane A2 synthetase inhibitors (e.g., ozmagrel, damegrelide, or ozagrel); ditec (low-dose disodium cromoglycate and fenoterol); platelet-activating factor receptor antagonists; antihistamines or histamine antagonists: promethazine, chlorpheniramine, loratadine, cetirazine, azelastine; thromboxane A2 receptor antagonists; bradykinin receptor antagonists (e.g., icatibant); agents that inhibit activated eosinophils and T-cell recruitment (e.g., ketotifen), IL-13 blockers (e.g., soluble IL-13 receptor fragments), IL-4 blockers (e.g., soluble IL-4 receptor fragments); and ligands that bind to and block the activity of IL-13 or IL-4, as well as xanthine derivatives (e.g., pentoxifylline); and chemokine receptor antagonists and CRTH2 receptor antagonists.
[0226] In certain embodiments, the treatment methods of the present invention include providing inhibitory RNA molecules (RNA interference molecules) to the subject concomitantly to reduce, inhibit or prevent the expression of genes encoding target proteins. For example, inhibitory RNA molecules can be used to reduce or inhibit the expression of one or more of the following: proteins associated with pathogens (viruses, bacteria, fungi) or mammalian cells, including but not limited to casein kinase 1 isoforms and other components of the CLOCK regulatory network (e.g., ARNT1, cycle 1-3) and other proteins that contribute to inflammatory responses in the respiratory system, such as interleukin-5 and NALP inflammasomes.
[0227] The skilled person is familiar with various methods of using inhibitory RNA molecules to interfere with gene expression in a subject. For example, the inhibitory RNA molecule can be any of the following: short interfering RNA (siRNA), microRNA mimics (miRNA), short hairpin RNA (shRNA) or long double-stranded RNA (long dsRNA) molecules. The inhibitory RNA molecule can be directly applied to the subject in need of treatment (e.g., by inhalation, intratracheal, oral or nasal administration or by parenteral administration), or alternatively, after administering a polynucleotide (vector) construct encoding a double-stranded RNA (dsRNA) molecule (which is capable of forming an inhibitory RNA molecule), the inhibitory RNA molecule is formed in the subject receiving treatment. Those skilled in the art are also familiar with various methods known in the art for preparing inhibitory RNA molecules for administration (e.g., in liposomes, nanoparticles, etc.). The present invention also includes the administration of a casein kinase 1 inhibitor and a drug for the above-mentioned target disease indication, wherein either or both are administered by inhalation or formulated for oral administration.
[0228] Although the present invention is suitable for use in humans, the present invention may also be used for veterinary therapeutic purposes. The present invention is useful for livestock or farm animals, such as cattle, sheep, horses and poultry, for companion animals such as cats and dogs, and for animals in zoos.
[0229] As used herein, "subject" refers to an animal, such as a mammal or bird, including humans, apes, horses, cows, sheep, goats, dogs, cats, guinea pigs, rats, mice, chickens, etc.
[0230] CK1δ homologues are ubiquitous in nature, including in protozoa (such as malaria), fungi and bacteria. Therefore, it is expected that the compounds of the present invention can be used in any application where inhibition of CK1δ homologues is required. Such uses may include administering the compounds of the present invention to a subject suffering from a disease, disorder and / or condition associated with infection and / or protozoan, fungal and / or bacterial infection.
[0231] In another aspect, the present invention provides a method for inhibiting casein kinase 1δ (CK1δ), comprising contacting a cell with an effective amount of a compound of formula (I) as defined herein, or a salt, solvate, N-oxide, tautomer, stereoisomer, polymorph and / or prodrug thereof.
[0232] Surprisingly, the compounds of the present invention, or salts, solvates, N-oxides, tautomers, stereoisomers, polymorphs and / or prodrugs thereof, can be used as selective inhibitors of CK1δ. Any disclosed form of the compounds of the present invention can selectively inhibit CK1δ compared to one or more other kinases, such as ALK5 / TGFBR1, ARK5 / NUAK1, casein kinase 1ε (CK1ε), p38a / MAPK14, etc. In some embodiments, the selectivity of the compounds of the present invention for CK1δ can exceed at least one kinase by at least about 1, 5, 10, or 100 times.

[0262] Primary human parenchymal fibroblasts (pFb) were cultured from the parenchyma of lung resection specimens and non-transplanted lungs of donors without chronic respiratory diseases. pFb were passaged in Dulbecco's Modified Eagle's Medium (DMEM) containing 10% (v / v) heat-inactivated fetal calf serum (FCS), 15mM HEPES, 0.2% (v / v) sodium bicarbonate, 2mM L-glutamine, 1% (v / v) non-essential amino acids, 1% (v / v) sodium pyruvate, 2.5μg / mL amphotericin, 5IU / mL penicillin and 50μg / mL streptomycin.

Cells were incubated with small molecule CK1δelta inhibitors (0.1 μM to 10 μM) for 30 minutes and then incubated with 100 pM TGF-β1 (R&D Systems, Minneapolis, MN) for 16 to 24 hours, and then supernatants were collected to detect immunoreactive IL-11. A 10 mM stock solution was made in 100% DMSO and diluted to the desired concentration (final concentration) in medium containing 0.1% DMSO.
[0264] The supernatant was collected and IL-11 was measured by ELISA according to the manufacturer's instructions (R&D DuoSet, DY218). Typically, the capture antibody was initially diluted to the recommended concentration using PBS buffer and then used to coat the wells of a 96-well microplate (Greiner, #655061) by adding 50 μL / well and incubating overnight at room temperature. The next day, the solution was discarded and the wells were washed 3 times with wash buffer (PBS containing 0.1% (v / v) Tween-20), followed by the addition of 200 μL of blocking solution (PBS containing 1% (v / v) BSA) for 1 hour to block nonspecific sites. The plate was then washed 3 times with wash buffer, and 50 μL of sample or standard was then added to the wells and incubated for 2 hours at room temperature. After incubation, the plate was washed 3 times with wash buffer, 50 μL of detection antibody was added to the wells and incubated for 2 hours at room temperature. The plates were then washed three times before adding streptavidin-conjugated horseradish peroxidase (at the recommended concentration) for 45 minutes. The plates were then washed five times with wash buffer and 100 μL of TMB substrate solution (A and B equal parts, BD Biosciences) was added to each well until sufficient signal appeared. The reaction was inactivated by adding 100 μL of sulfuric acid (2M H2SO4). The plate was analyzed using Multiskan The plate reader measures absorbance at 450 nm. The absorbance of the cytokine standards is fit to a logistic equation, allowing the concentration of the cytokine in the sample to be determined.
