Description

[Technical field]

[0001] The present invention relates to novel medicamentously useful compounds, particularly compounds which are angiotensin II (Ang II) agonists, more particularly agonists of the Ang II type 2 receptor (hereinafter AT2 receptor), especially agonists which selectively bind to that receptor. The invention further relates to the use of such compounds as medicaments, pharmaceutical compositions containing them, and synthetic routes to their preparation. [Background technology]

[0002] The protease renin cleaves its only known substrate (angiotensinogen) to form angiotensin I (Ang I), which then serves as a substrate for angiotensin converting enzyme (ACE) to form Ang II. The endogenous hormone Ang II is a linear octapeptide (Asp 1 -Arg 2 -Val 3 -Tyr 4 -Ile 5 -His 6 -Pro 7 -Phe 8 ), an active component of the renin-angiotensin system (RAS). Angiotensin II type 1 (AT1) receptors are expressed in most organs and are thought to be responsible for most of the pathological effects of Ang II.

[0003] Several studies in adult individuals appear to demonstrate that activation of the AT2 receptor has an effect opposing that mediated by the AT1 receptor in modulating responses following Ang II receptor stimulation. The AT2 receptor has also been shown to be involved in the inhibition of apoptosis and cell proliferation (de Gasparo M et al., Pharmacol. Rev. (2000); 52, 415-472). More recently, AT2 receptor agonists have been shown to be of potential utility in the treatment and / or prevention of disorders of the gastrointestinal tract, such as dyspepsia and irritable bowel syndrome, as well as multiple organ failure (see International Patent Application No. 99 / 43339). The expected pharmacological effects of AT2 receptor agonism are generally described in de Gasparo M et al. (see above).

[0004] The stimulatory effects of Ang II on vascular tone, cell proliferation, inflammation, and extracellular matrix synthesis are primarily mediated by AT1 receptors in any organ, whereas AT2 receptor function appears to be more prevalent in damaged tissues, exerting reparative and opposing properties to AT1 receptors. For example, AT2 receptors have been shown to be important for myocyte hypertrophy and reduction of fibrosis.

[0005] Interstitial lung diseases (ILDs) are a group of lung diseases that affect the interstitium and are characterized by scarring and / or thickening of the tissue surrounding the alveoli, thereby impeding the breathing process.

[0006] ILDs differ from obstructive airway diseases (e.g., chronic obstructive airway disease (COPD) and asthma), which are usually characterized by narrowing (obstruction) of the bronchi and / or bronchioles. ILDs can be caused by injury to the lungs, triggering an abnormal healing response, although in some cases the cause of these diseases is unknown. ILDs may be caused by chemicals (silicosis, asbestosis, certain drugs), infections (e.g., pneumonia), or other diseases (e.g., rheumatoid arthritis, systemic sclerosis, myositis, or systemic lupus erythematosus).

[0007] The most common ILDs are idiopathic pulmonary fibrosis (IPF) and sarcoidosis, both of which are characterized by chronic inflammation and reduced lung function.

[0008] Sarcoidosis is a disease of unknown cause characterized by collections of inflammatory cells that form masses (granulomas) and often begins in the lungs (as well as the skin and / or lymph nodes, although any organ may be affected.) When sarcoidosis affects the lungs, symptoms include coughing, wheezing, shortness of breath, and / or chest pain.

[0009] Treatment of sarcoidosis is patient-specific: most cases can be treated symptomatically with nonsteroidal anti-inflammatory drugs (NSAIDs), but patients with pulmonary manifestations often receive glucocorticoids (e.g., prednisone or prednisolone), antimetabolites, and / or monoclonal anti-tumor necrosis factor antibodies.

[0010] IPF is a lung disease of unknown etiology that affects approximately 5 million people worldwide. There are no curative treatment options, except for lung transplantation, which, in rare cases, leads to a chronic, irreversible, progressive deterioration of lung function and, in most cases, death within 2-5 years (median survival 2.5-3.5 years). The overall prognosis is poor in IPF, but it is difficult to predict the rate of progression in individual patients. Risk factors for IPF include age, male sex, genetic predisposition, and smoking history. The annual incidence is 5-16 per 100,000 people, and the prevalence is 13-20 cases per 100,000 people, increasing dramatically with age (King Jr TE et al., Lancet (2011); 378, 1949-1961; Noble PW et al., J. Clin. Invest. (2012); 122, 2756-2762). IPF is distinct from pulmonary fibrosis, which is associated with systemic disease, in that it is confined to the lungs and is refractory to therapies that target the immune system.

[0011] Patients with IPF usually seek medical assistance due to chronic and progressive exertional dyspnea and cough. Pulmonary imaging classically reveals traction bronchiectasis, thickened interlobar septa, and subpleural honeycombing. When all three signs are present and there is no evidence of systemic connective tissue disease or environmental exposure, the diagnosis of IPF is highly likely. Definitive diagnosis is usually made by lung biopsy and requires a multidisciplinary team of expertise including pulmonologists, radiologists, and pathologists experienced in interstitial lung disease.

[0012] IPF presents different phenotypes with different prognoses defined as mild, moderate, and severe. Mild cases follow a stable or slowly progressive course, and patients may take years to seek medical advice. Rapid IPF shows a more rapid progression, shortens survival, and affects a subgroup of patients, usually male smokers. Acute exacerbations of IPF are defined as a rapid worsening of the disease, and this subpopulation of patients shows a very poor outcome with a high mortality rate in the short run. The cause of IPF is unknown, but it appears to be a disorder that likely results in unabated tissue remodeling by fibroblasts rather than normal repair from an interplay of environmental and genetic factors, with a pathogenesis that is primarily fibrotic rather than inflammatory. Growing evidence suggests that the disease is initiated through microdamage and apoptosis of alveolar epithelial cells, activating neighboring epithelial cells and attracting stem or progenitor cells that produce factors involved in the expansion of fibroblast and myofibroblast populations in a tumor-like manner. Fibroblast nests secrete excessive amounts of extracellular matrix that destroys the lung parenchyma and ultimately leads to loss of lung function.

[0013] The average annual rate of decline in lung function (vital capacity) ranges from 0.13 to 0.21 liters. Symptoms precede diagnosis by 1 to 2 years, and radiographic signs may precede symptoms (Ley B et al., Am. J. Respir. Crit. Care Med. (2011);183,431-440).

[0014] Many therapeutic approaches have been tested in preclinical models and clinical trials, including anti-inflammatory, immunomodulatory, cytotoxic, general antifibrotic, antioxidant, anticoagulant, antichemokine, antiangiogenic drugs as well as RAS blockers, endothelin antagonists, and sildenafil, and have essentially been shown to provide limited or no benefit (Rafii R et al., J. Thorac. Dis. (2013);5,48-73).

[0015] Current treatments for IPF include supplemental oxygen. Medications used include pirfenidone or nintedanib, but they have limited effectiveness in slowing disease progression. Furthermore, both of these drugs generally cause side effects (mainly gastrointestinal).

[0016] There are drawbacks associated with all of the aforementioned pharmacological treatments for ILD (and IPF) and there is a compelling clinical need for safer and / or more effective treatments.

[0017] Restoring the alveolar epithelium is a highly desirable therapeutic effect in IPF, and therefore stem cell therapy is also being tested. Several preclinical studies have shown that the use of pluripotent stem cells can differentiate into pulmonary epithelial and endothelial cells, which may repair lung injury and fibrosis.

[0018] Currently, lung transplantation is the only intervention that substantially improves survival in patients with IPF, however complications such as infection and graft rejection are significant.

[0019] Therefore, the development of new therapeutic strategies for IPF is important. Therefore, a fundamental challenge for the future is to develop appropriate therapeutic approaches to reverse or halt the progression of the disease.

[0020] US Patent Application No. 2004 / 0167176 describes the preparation of tricyclic heterocycles useful as Ang II receptor agonists.

[0021] Selective AT2 receptor agonists with reduced CYP450 inhibition are described in Mahalingam et al., Bioorg. Med. Chem. (2010); 18, 4570-4590.

[0022] A transesterification method for the synthesis of AT2 receptor ligands with improved stability in human liver microsomes is described in Wannberg et al., Bioorg. Med. Chem. Lett. (2018); 28, 519-522.

[0023] Specifically, International Patent Application No. 2002 / 096883 describes the preparation of imidazolyl, triazolyl, and tetrazolylthiophene sulfonamides and derivatives as AT2 receptor agonists. Among the compounds described in that document (as Example 1) is compound C21 (N-butyloxycarbonyl-3-(4-imidazol-1-ylmethylphenyl)-5-isobutylthiophene-2-sulfonamide). C21 was selected for clinical development from a group of about 20 related analogues as a selective AT2 receptor agonist. It is currently in clinical development for the treatment of AT2 receptor-related disorders, including IPF (see, for example, International Publication No. WO 2016 / 139475).

[0024] C21 has also been indicated for potential use in the treatment of stroke, spinal cord injury, sickle cell disease, muscular dystrophy, cardiotoxicity associated with cancer therapy, peripheral neuropathy, and systemic sclerosis, among others (see, e.g., International Patent Applications Nos. 2004 / 046141, 2016 / 092329, 2016 / 107879, 2016 / 139475, 2017 / 221012, 2019 / 008393, and U.S. Patent Application No. 2012 / 035232).

[0025] During development, C21 was found to be a potent inhibitor of several cytochrome P450 enzymes (CYPs), particularly CYP 2C9 and CYP 3A4, which potentially affect the metabolism of other drugs, and also has the drawback of being rapidly hydrolyzed to inactive sulfonamide metabolites. Therefore, it is a fundamental challenge to develop potent and selective AT2 agonists that are metabolically stable and / or have low inhibition of CYP enzymes.

[0026] Surprisingly, it has been found that certain chemically modified compounds, as defined below, are not only selective AT2 receptor agonists, but are also more potent, have significantly improved stability against metabolic hydrolysis and / or exhibit less inhibition of CYP enzymes compared to C21.

[0029] Compounds may be named according to the IUPAC nomenclature system, generated by the program Chemdoodle 8.1.0.

[0030] For the avoidance of doubt, those skilled in the art will understand that reference herein to a compound of a particular aspect of the invention (such as any aspect of the invention, which refers to a compound of formula I as defined herein above) includes reference to all embodiments and specific features thereof, which embodiments and specific features may be combined to form further embodiments and features of the invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0032] Pharmaceutically acceptable salts include acid addition salts and base addition salts. Such salts may be formed by conventional means, for example, by reacting the free acid or free base form of the compound of the present invention with one or more equivalents of a suitable acid or base, optionally in a solvent or in a medium in which the salt is insoluble, and then removing the solvent or medium using standard techniques (for example, by vacuum, lyophilization or filtration). Salts may also be prepared using techniques known to those skilled in the art, for example, by exchanging the counterion of the compound of the present invention in the form of a salt with another counterion using a suitable ion exchange resin.

[0035] The compounds of the present invention may exist as solids, and therefore the scope of the present invention includes all amorphous, crystalline, and partially crystalline forms thereof, and may also exist as oils. When the compounds of formula I exist in crystalline and partially crystalline forms, such forms may include solvates, which are also included within the scope of the present invention.

[0036] The compounds of the present invention may also be present in solution (i.e. in a solution in a suitable solvent). For example, the compounds of formula I may be present in aqueous solution, in which case the compounds of the present invention may be present in the form of hydrates.

[0037] The compounds of the present invention may contain double bonds and therefore, unless otherwise indicated, may exist as E (entgegen) and Z (zusammen) geometric isomers about each individual double bond. Unless otherwise specified, all such isomers and mixtures thereof are included within the scope of the present invention.

[0038] The compounds of the invention may also exhibit tautomerism, and all tautomers and mixtures thereof (especially those with sufficient stability to allow their isolation) are included within the scope of the invention.

[0039] The compounds of the present invention may also contain one or more asymmetric carbon atoms and therefore may exhibit optical isomerism and / or diastereoisomerism (i.e., may exist in enantiomeric or diastereomeric forms). Diastereomers may be separated using conventional techniques, for example, chromatography or fractional crystallization. The various stereoisomers (i.e., enantiomers) can be isolated by separating racemic or other mixtures of the compounds using conventional, for example, fractional crystallization or HPLC techniques. Alternatively, the desired enantiomer or diastereomer can be obtained from suitable optically active starting materials under conditions that will not cause racemization or epimerization (i.e., the "chiral pool" method), by reaction of the appropriate starting materials with a "chiral auxiliary" that can be subsequently removed at a suitable stage, by derivatization (i.e., resolution, including kinetic resolution, for example, treatment with a homochiral acid followed by separation of the diastereomeric derivatives by conventional means such as chromatography), or by reaction with a suitable chiral reagent or chiral catalyst, all of which methods and processes may be carried out under conditions known to those skilled in the art. Unless otherwise specified, all stereoisomers and mixtures thereof are included within the scope of the present invention.

[0040] As used herein, the term "halogen" includes fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Similarly, the term "halo" includes fluoro, chloro, bromo, and iodo.

[0041] Unless otherwise specified, C as defined herein 1-6 Alkyl groups (e.g., C 1-2 Alkyl group), C 2-4 Alkyl groups, and C 1-6 Alkoxy, C 1-6 Alkoxy-C 1-6 Alkyl, C 1-6 Alkylaryl, C 1-3 Alkenylaryl, C 1-6 Alkylheteroaryl, and C 1-3The alkyl portion of the alkenylheteroaryl group can be linear or, when there is a sufficient number (i.e., a minimum of 2 or 3, as appropriate) of carbon atoms, can be branched and / or cyclic (e.g., C 3-6 When there is a sufficient number (i.e., a minimum of four) of carbon atoms, such groups may also be part cyclic (e.g., C 4-6 (which may form a partial cycloalkyl group). For example, cycloalkyl groups that may be mentioned include cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl. Similarly, partial cyclic alkyl groups (which may also be referred to as "partial cycloalkyl" groups) that may be mentioned include cyclopropylmethyl. When a sufficient number of carbon atoms are present, such groups may also be polycyclic (e.g., bicyclic or tricyclic) and / or spirocyclic.

[0042] The alkyl and alkoxy groups, when there is a sufficient number (ie, a minimum of three) of carbon atoms, may be unsaturated and thus incorporate double or triple bonds.

[0043] Particular alkyl groups that may be mentioned include linear (i.e., not branched and / or cyclic) alkyl groups. For example, 1-6 Alkyl groups, and C 1-6 The alkyl portion of the alkoxy group includes, but is not limited to, n-butyl, sec-butyl, isobutyl, tert-butyl; propyl, such as n-propyl, 2-methylpropyl, or isopropyl; ethyl; and methyl.

[0044] For the avoidance of any doubt, C 1-6 Alkyl groups and C 1-6 Alkoxy-C 1-6 Alkyl, C 1-6 Alkylaryl, C 1-3 Alkenylaryl, C 1-6 Alkylheteroaryl, and C 1-3 The point of attachment of the alkenylheteroaryl group to the alkyl portion of such group is through the alkyl portion of such group.

[0045] For the avoidance of doubt, alkoxy groups are bonded to the remainder of the molecule through the oxygen atom of the group, and alkoxyalkyl groups are bonded to the remainder of the molecule through the alkyl moiety of the group.

[0046] Unless otherwise specified, alkoxy refers to an O-alkyl group, where the term "alkyl" has the meaning given above.

[0047] As used herein, references to heteroatoms shall take their ordinary meaning as understood by those of ordinary skill in the art. Particular heteroatoms that may be mentioned include phosphorus, selenium, tellurium, silicon, boron, oxygen, nitrogen and sulfur (e.g., oxygen, nitrogen and sulfur, such as oxygen and nitrogen).

[0048] As may be used herein, reference to a "heteroaryl" (which may also be referred to as heteroaromatic) ring or group may refer to a heteroaromatic group containing one or more heteroatoms (such as one or more heteroatoms selected from oxygen, nitrogen, and / or sulfur). Such heteroaryl groups may contain one, two, or three rings, at least one of which is aromatic (which aromatic ring may or may not contain one or more heteroatoms). Substituents on the heteroaryl / heteroaromatic group, where appropriate, may be located on any suitable atom in the ring system that contains a heteroatom (e.g., on a suitable N atom).

[0049] The point of attachment of the heteroaryl / heteroaromatic group may be via any atom of the ring system including (where appropriate) a heteroatom. Bicyclic heteroaryl / heteroaromatic groups may contain a benzene ring fused to one or more further aromatic or non-aromatic heterocyclic rings, in which case the point of attachment of the polycyclic heteroaryl / heteroaromatic group may be via the benzene ring or any ring comprising the heteroaryl / heteroaromatic or heterocyclic ring.

[0050] For the avoidance of doubt, those skilled in the art will understand that the heteroaryl groups which may form part of the compounds of the present invention are those which are chemically obtainable, as known to those skilled in the art. A variety of heteroaryl groups, such as pyridinyl, pyrrolyl, furanyl, thiophenyl, oxadiazolyl, thiadiazolylthiazolyl, oxazolyl, pyrazolyl, triazolyl, tetrazolyl, isoxazolyl, isothiazolyl, imidazolyl, imidazopyrimidinyl, imidazothiazolyl, thienothiophenyl, pyrimidinyl, furopyridinyl, indolyl, azaindolyl, pyrazinyl, pyrazolopyrimidinyl, indazolyl, pyrimidinyl, quinolinyl, isoquinolinyl, quinazolinyl, benzofuranyl, benzothiophenyl, benzimidazolyl, benzoxazolyl, benzothiazolyl, benzotriazolyl, and purinyl, will be known to those skilled in the art.

[0051] For the avoidance of doubt, oxides (eg, N-oxides) of heteroaryl / heteroaromatic groups are also encompassed within the scope of the present invention.

[0052] As mentioned above, heteroaryl includes polycyclic (e.g., bicyclic) groups in which one ring is aromatic (the other may or may not be aromatic).Other heteroaryl groups that may be mentioned thus include benzo[1,3]dioxolyl, benzo[1,4]dioxinyl, dihydrobenzo[d]isothiazole, 3,4-dihydrobenzo[1,4]oxazinyl, dihydrobenzothiophenyl, indolinyl, 5H,6H,7H-pyrrolo[1,2-b]pyrimidinyl, 1,2,3,4-tetrahydroquinolinyl, thiochromanyl, and other groups.

[0053] As used herein, the term aryl refers to C 6-14 (For example, C 6-10 ) aromatic groups. Such groups may be monocyclic or bicyclic, and if bicyclic, may be either fully aromatic or partially aromatic. 6-10Aryl groups include phenyl, naphthyl, 1,2,3,4-tetrahydronaphthyl, indanyl, and the like (eg, phenyl, naphthyl, and the like).

[0054] An aromatic group may be represented as a cyclic group containing a suitable number of double bonds therein to permit aromaticity.

[0055] Those skilled in the art will recognize that the aryl groups that may form part of the compounds of the present invention are chemically available, as known to those skilled in the art.

[0056] For the avoidance of doubt, the point of attachment of substituents on an aryl group may be via any suitable carbon atom of the ring system.

[0057] The present invention also includes isotopically labeled compounds of the present invention, in which one or more atoms are actually replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature (or most abundantly found in nature), but are the same as described herein.All isotopes of any specific atom or element specified herein are contemplated within the scope of the compounds of the present invention.Therefore, the compounds of the present invention also include deuterated compounds, i.e., compounds of the present invention in which one or more hydrogen atoms are replaced by the hydrogen isotope deuterium.

[0058] In the case where the identity of two or more substituents in the compound of the present invention may be the same, the actual identity of each substituent is in no way mutually dependent.For example, in the situation where two or more halo groups are present, those groups may be the same or different (e.g., two chloro groups, or a fluoro group and a chloro group).Similarly, when two or more alkyl groups are present, the groups in question may be the same or different in terms of their number of carbon atoms and / or in terms of whether they are linear, branched, unsaturated, or otherwise.

[0059] Further, when a substituent is itself specified as being optionally substituted with one or more substituents (e.g., butyl optionally substituted with one or more groups independently selected from halo), these substituents may be located on the same or different atoms, where possible. Such optional substituents may be present in any suitable number thereof (e.g., the relevant group may be substituted with one or more such substituents, such as one such substituent).

[0060] Where a group is referred to herein as being optionally substituted, it is specifically contemplated that such optional substituents may be absent (i.e., reference to such optional substituents may be omitted), in which case the optionally substituted group may be referred to as unsubstituted.

[0061] Unless otherwise specified, substituents (whether optional or not) may be located at any point on the group to which they may be attached. In this regard, alkyl and alkoxy groups (for example) which may be substituted by one or more substituents may also be terminated by such a substituent (i.e., meaning located at the end of the alkyl or alkoxy chain).

[0062] For the avoidance of doubt, where the identities of two or more substituents in a compound of formula I may be the same, the actual identities of the respective substituents are in no way interdependent. For example, R 2 and R 3 Both are C 1-6 In the case of alkyl, the C in question 1-6 The alkyl groups can be the same or different.

[0063] Those of skill in the art will appreciate that the compounds of the invention that are the subject of the present invention include those that are available, i.e., that can be prepared in a stable form, i.e., compounds of the present invention include compounds that are sufficiently robust to survive isolation, e.g., isolation to a useful degree of purity from a reaction mixture.

[0064] Preferred compounds of the present invention include R 1 represents a methyl or ethyl group, which is optionally substituted by up to three fluorine atoms (e.g., CH2CF3), R 2 and R 3 independently represents H or C optionally substituted by up to three halogen atoms; 1-4 represents an alkyl group (such as methyl, ethyl, propyl (e.g., n-propyl), or butyl (e.g., n-butyl)) (e.g., CH2CHClCH2CH2F or CH2CF3); Y 1 represents -CH-, -CF-, or -N-; Y 2 represents -CH- or -CF-; Y 3 represents -CH-; Y 4 represents -CH- or -N-; R 4 But, C 1-4 Alkyl groups (such as ethyl, propyl (e.g., n-propyl or isopropyl), or butyl (e.g., tert-butyl, isobutyl, or n-butyl), etc.); 1-4 Alkoxy-C 1-4 Alkyl (e.g. methoxyethyl), phenyl, C 1-3 Alkylaryl or C 1-3 each of which is optionally substituted or terminated with up to three halogen atoms (such as F); R 5 represents H or C 1-4 represents an alkyl group (such as methyl, ethyl, propyl (e.g., n-propyl), or butyl (e.g., isobutyl), R 6 represents ethyl, propyl (eg, n-propyl), or butyl (eg, n-butyl) optionally substituted by one or more halogens.

[0065] More preferred compounds of the present invention include R1 Methyl, OR 7 or a fluorine atom, R 2 and R 3 each independently represents H or methyl; Y 1 , Y 2 , Y 3 , and Y 4 represents independently -CH- or -CF-; R 5 represents H, methyl, ethyl, n-propyl, n-butyl, or isobutyl; R 6 represents n-propyl, n-butyl, or isobutyl, optionally substituted or more preferably terminated by up to three fluorine atoms; R 7 represents H or methyl.

[0066] Particularly preferred compounds of the present invention include R 1 represents methyl, R 2 and R 3 But both represent H, Y 1 represents -CH- or -CF-; Y 2 , Y 3 , and Y 4 are all -CH-, R 4 represents ethyl, n-propyl, or n-butyl, optionally terminated by up to three fluorine atoms; methoxyethyl; benzyl; 2-methylfuryl, 2-methylthiophenyl, or 2-methylpyridyl, R 5 represents H, R 6 However, examples thereof include isobutyl.

[0067] Thus, preferred compounds of the invention that may be mentioned are: Furan-2-ylmethyl-3-[[5-isobutyl-3-[4-[(2-tert-butyl-imidazol-1-yl)methyl]phenyl]-2-thienyl]sulfonyl]urea, Thiophene-2-ylmethyl-3-[[5-isobutyl-3-[4-[(2-tert-butyl-imidazol-1-yl)methyl]phenyl] -2-thienyl]sulfonylurea, 2-Methoxyethyl-3-[[5-isobutyl-3-[4-[(2-tert-butyl-imidazol-1-yl)methyl]phenyl]-2-thienyl]sulfonylurea, pyridin-2-ylmethyl-3-[[5-isobutyl-3-[4-[(2-tert-butyl-imidazol-1-yl)methyl]phenyl]-2-thienyl]sulfonylurea, 1-[[3-[4-[(2-tert-butylimidazol-1-yl)methyl]-3-fluoro-phenyl]-5-isobutyl-2-thienyl]sulfonyl]-3-(2-pyridylmethyl)urea, 1-[[3-[4-[(2-tert-butylimidazol-1-yl)methyl]-3-fluoro-phenyl]-5-isobutyl-2-thienyl]sulfonyl]-3-ethyl-urea, or 1-[[3-[4-[(2-tert-butylimidazol-1-yl)methyl]-3-fluoro-phenyl]-5-isobutyl-2-thienyl]sulfonyl]-3-(2-thienylmethyl)urea.

[0079] It will be appreciated by those skilled in the art that in the processes described above and below, the functional groups of intermediate compounds may need to be protected by protecting groups.

[0080] Functional groups that are desirable to be protected include sulfonamide, amide, amino, and aldehyde.

[0081] Protective groups can be applied and removed according to techniques well known to those skilled in the art and described below. For example, the protected compounds / intermediates described herein can be chemically converted to unprotected compounds using standard deprotection techniques. The type of chemical reaction involved will dictate the need and type of protecting groups, as well as the sequence for accomplishing the synthesis. The use of protecting groups is fully described in "Protective Groups in Organic Synthesis", 3rd edition, TW Greene & P. ​​GMWutz, Wiley-Interscience (1999), the contents of which are incorporated herein by reference.

[0082] Medical and pharmaceutical uses As described herein, the compounds of the invention, and thus compositions and kits comprising same, are useful because they have pharmacological activity and / or are metabolized in the body following oral or parenteral administration to form compounds that have pharmacological activity.

[0083] Thus, according to a further aspect of the invention there is provided a compound of the invention as defined below for use as a pharmaceutical (or for use as a medicament).

[0084] In particular, the compounds of the invention are agonists of the AT2 receptor and are therefore expected to be useful in conditions where there is a deficiency in endogenous production of Ang II and / or where increased activity of the AT2 receptor is desirable or required.

[0085] More specifically, the compounds of the invention are agonists of the AT2 receptor and, in particular, selective agonists of its sub-receptors (vs. the AT1 receptor), as can be demonstrated, for example, in the tests described below.

[0086] AT2 receptor agonists include those that fully activate AT2 receptors and those that partially activate AT2 receptors.Therefore, the compounds of the present invention can selectively bind to AT2 receptors and exhibit agonist activity at AT2 receptors.A compound that "selectively binds" to AT2 receptors includes that the affinity ratio (AT2:AT1) of related compounds at a given concentration is at least 50:1, such as at least 100:1, preferably at least 1000:1.

[0087] Compounds of the invention are further expected to be useful in conditions where AT2 receptors are expressed and their stimulation is desirable or required.

[0088] In this regard, the compounds of the invention are indicated in the treatment of conditions characterized by vasoconstriction, fibrosis, increased cell proliferation and / or differentiation, increased myocardial contractility, increased cardiovascular hypertrophy, and / or increased fluid and electrolyte retention, as well as skin and musculoskeletal disorders.

[0100] The compounds of the invention are also useful in the treatment of stroke, spinal cord injury, sickle cell disease, muscular dystrophies, cancer therapy-related cardiotoxicity, peripheral neuropathy, and particularly systemic sclerosis.

[0101] The compounds of the invention are particularly indicated in the treatment and / or prevention of ILDs such as sarcoidosis or fibrosis, more particularly pulmonary fibrosis and especially IPF, as well as conditions which may induce an ILD, such as systemic sclerosis, rheumatoid arthritis, myositis or systemic lupus erythematosus, or conditions which are associated with an ILD, such as pulmonary hypertension and / or pulmonary arterial hypertension.

[0102] The compounds of the invention are particularly useful in the treatment of pulmonary fibrosis, particularly IPF.

[0103] According to a further aspect of the invention there is provided a method of treatment of pulmonary fibrosis, in particular IPF, which comprises administering to a human suffering from such a condition a therapeutically effective amount of a compound of the invention.

[0104] In the treatment of pulmonary fibrosis, including IPF, the compounds of the present invention may have anti-fibrotic effects, involving reduction of fibrosis and prevention of further deposition of extracellular matrix. The compounds of the present invention may reduce lung scarring / wound healing, and may also have anti-apoptotic effects, thereby preventing the apoptosis of alveolar endothelial cells, which is an initiator of the development of pulmonary fibrosis. The compounds of the present invention may also have anti-proliferative effects, thus reducing the cancer-like proliferation of fibroblasts and myofibroblasts in pulmonary fibrosis. The compounds of the present invention may also improve vascular remodeling in pulmonary fibrosis, thereby reducing secondary pulmonary hypertension. Finally, the compounds of the present invention may exhibit anti-inflammatory, anti-growth factor (e.g., transforming growth factor beta), and / or anti-cytokine effects.

[0105] In addition, the compounds of the present invention may also be useful in the treatment or prevention of any fibrotic condition of one or more internal organs characterized by excessive accumulation of fibrous connective tissue, and / or in the treatment or prevention of fibrosis and the morbidity and mortality that may be associated therewith. Such fibrosis may be associated with acute inflammatory conditions such as acute respiratory distress syndrome (ARDS), severe acute respiratory syndrome (SARS), multiorgan inflammation, injury and / or failure that may be caused by internal or external trauma (e.g., injury) or by infectious disease.

[0106] Thus, such conditions may result from sepsis or septic shock caused by viral, bacterial, or fungal infections (e.g., viral airway infections). Furthermore, acute lung injury, ARDS, and especially SARS, may be caused by viruses such as coronaviruses, including novel SARS coronavirus 2 (SARS-CoV-2), which may result in internal tissue damage and / or dysfunction of relevant internal (e.g., mucosal) tissues, such as the respiratory epithelium, thus resulting in virus-induced pneumonia, low lung function, respiratory dysfunction, dyspnea, and / or respiratory failure. Such tissue damage may also result in severe fibrosis. For example, SARS disease (coronavirus disease 2019 or COVID-19), caused by the novel coronavirus SARS-CoV-2, is known to often result in fibrosis.

[0107] The compounds of the present invention are particularly useful in the treatment of diseases or conditions in which activation of the AT2 receptor is desirable or required, but inhibition of one or more CYP enzymes is undesirable.

[0138] When the compounds of the present invention are "combined" with other therapeutic agents mentioned hereinabove, the active ingredients may be administered together in the same formulation or separately (simultaneously or sequentially) in different formulations.

[0139] Such combination products provide for administration of a compound of the invention in conjunction with another therapeutic agent and therefore may be presented as separate formulations, at least one of which contains a compound of the invention and at least one of which contains the other therapeutic agent, or may be presented (i.e., formulated) as a combined preparation (i.e., presented as a single formulation containing a compound of the invention and the other therapeutic agent).

[0140] therefore, (1) A pharmaceutical formulation comprising a compound of the present invention; a therapeutic agent selected from those described above (e.g., known to be metabolized by a CYP enzyme); and a pharma- ceutically acceptable excipient (e.g., an adjuvant, diluent, or carrier), hereinafter referred to as a "combination preparation"; (2) A kit of parts comprising the following components: (A) a pharmaceutical formulation comprising a compound of the invention in admixture with a pharma- ceutically acceptable adjuvant, diluent, or carrier; and (B) a pharmaceutical formulation comprising a therapeutic agent selected from those described above (e.g., one known to be metabolized by a CYP enzyme) in admixture with a pharma- ceutically acceptable adjuvant, diluent, or carrier; There is further provided a kit-of-parts, in which components (A) and (B) are each provided in a form suitable for administration in conjunction with the other.

[0141] In a further aspect of the present invention, there is provided a process for the preparation of a combination preparation as defined herein above, comprising bringing into association a compound of the present invention, another anti-inflammatory agent, a therapeutic agent, with at least one (e.g., pharma- ceutically acceptable) excipient.

[0142] In a further aspect of the present invention, there is provided a process for the preparation of the kit-of-parts as defined herein above, the process comprising combining components (A) and (B). As used herein, reference to combining shall mean that the two components are suitable for administration in conjunction with each other.

[0143] Thus, with regard to the process for the preparation of a kit-of-parts as defined herein above by "combining" two components with each other, the two components of the kit-of-parts are (i) may be provided as separate formulations (i.e., independent of each other) and then combined for use in conjunction with each other in a combination therapy; or (ii) They may be packaged and presented together as separate components of a "combination pack" for use in conjunction with each other in combination therapy.

[0144] therefore, (I) one of components (A) and (B) as defined herein, (II) instructions for using the component in conjunction with the other of the two components.

[0145] Depending on the patient being treated and the route of administration, the compounds of the present invention may be administered in varying doses. Although the dose will vary from patient to patient, a suitable daily dose ranges from about 0.1 to about 1000 mg per patient (e.g., 0.1, 0.5, 1, 2, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000 mg, etc., or any range or value therein), administered in single or multiple doses. More preferred daily doses are in the range of about 0.1 to about 250 mg per patient (e.g., 0.2, 0.3, 0.4, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250 mg, etc., or any range or value therein). Particularly preferred daily doses range from about 0.3 to about 100 mg per patient.

[0146] Individual doses of the compounds of the invention can range from about 0.1 to about 100 mg (e.g., 0.3, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 mg, etc., or any range or value therein).

[0147] In any event, a physician or person skilled in the art can determine the actual dosage that will be most suitable for an individual patient, which is likely to vary with the condition being treated, as well as the age, weight, sex, and response of the particular patient being treated. The dosages mentioned above are exemplary of the average case, and there can, of course, be individual cases where higher or lower dosage ranges are merited, and such are within the scope of this invention.

[0148] The advantage of using the compounds of the present invention separately and / or sequentially and / or simultaneously in parallel via a combination of administration routes is to produce a tailored treatment for the patient in need of treatment, potentially preventing and / or reducing side effects, and also to tailor the correct dosage level of the therapeutically effective amount of the compounds of the present invention.

[0149] The kit-of-parts described herein may include two or more formulations containing suitable amounts / doses of the compounds of the invention and / or two or more formulations containing suitable amounts / doses of other therapeutic agents to provide for repeated administration. When two or more formulations (containing any active compound) are present, such formulations may be the same or different with respect to the dose, chemical composition and / or physical form of any compound.

[0150] "Administration in conjunction with" in reference to the kit of parts described herein includes sequential, separate and / or simultaneous administration of each formulation containing a compound of the invention and another therapeutic agent over the course of treatment of the relevant condition.

[0151] Thus, with respect to a combination product according to the invention, the term "administration in conjunction with" includes administration of the two components of the combination product (a compound of the invention and another therapeutic agent) together, or sufficiently close in time (optionally repeatedly) to permit a greater beneficial effect to the patient over the course of treatment of the relevant condition than if either a formulation containing the compound of the invention or a formulation containing the other agent were administered alone (optionally repeatedly) over the same course of treatment in the absence of the other component. The determination of whether a combination provides a greater beneficial effect with respect to and over the course of treatment of a particular condition depends on the condition being treated or prevented, but can be routinely accomplished by one of ordinary skill in the art.

[0152] Furthermore, in the context of the kit-of-parts according to the invention, the term "in conjunction with" includes that one or the other of the two formulations may be administered (optionally repeatedly) before, after and / or simultaneously with the administration of the other component. As used in this context, the terms "co-administered" and "administered simultaneously with" include administration of individual doses of the relevant compound of the invention and the other anti-inflammatory agent within 48 hours (e.g. 24 hours) of each other.

[0153] The pharmaceutical compositions / formulations, combination products and kits described herein may be prepared in accordance with standard and / or accepted pharmaceutical practice.

[0154] Therefore, in a further aspect of the present invention there is provided a process for the preparation of a pharmaceutical composition / formulation as defined hereinbefore, which comprises combining certain compounds of the present invention as defined hereinbefore with one or more pharma- ceutically acceptable excipients (e.g., adjuvants, diluents and / or carriers).

[0155] In a further aspect of the present invention, there is provided a process for the preparation of a combination product or kit-of-parts as defined hereinabove, the process comprising combining certain compounds of the present invention as defined hereinabove with other therapeutic agents useful in the treatment of the relevant disease or disorder, and at least one pharma- ceutically acceptable excipient.

[0156] Subjects suitable for treatment with the formulations of the present invention include, but are not limited to, mammalian subjects, particularly human subjects.

[0157] When used herein with respect to a particular value (such as an amount), the term "about" (or similar terms such as "approximately") will be understood as indicating that such value may vary by up to 10% (specifically up to 5%, such as up to 1%) of the defined value. In each case, it is contemplated that such terms may be replaced with the notation "±10%" or the like (or by indicating a particular amount of variation calculated based on the relevant value). It is also contemplated that in each case, such terms may be omitted.

[0158] The compounds of the present invention have the advantage that they are more potent than metabolic hydrolysis and / or are stable to metabolic hydrolysis and / or do not inhibit the CYP enzymes mentioned herein above.

[0159] The compounds described herein, whether for use in the treatment of IPF or not, may have the advantage that they may be more effective, less toxic, longer acting, more potent, have fewer side effects, be more readily absorbed, and / or have a superior pharmacokinetic profile (e.g., higher oral bioavailability and / or lower clearance), and / or have other useful pharmacological, physical or chemical properties than compounds known in the prior art. Such effects may be assessed clinically, objectively, and / or subjectively by a health care professional, a subject being treated, or an observer.

[0160] The present invention will be further described by reference to the following examples, which are not intended to limit the scope of the invention.

[0161] In case of discrepancy between the nomenclature and any compound depicted in the figures, the latter takes precedence (unless contradicted by any experimental details that may be provided and / or clear from the context).

[0162] Experimental procedure The starting materials and intermediates used in the synthesis of the compounds described herein are either commercially available or can be prepared by methods described herein or known in the art.

[0163] Experiments were generally performed under an inert atmosphere (nitrogen or argon), especially when oxygen- or moisture-sensitive reagents or intermediates were used.

[0164] Mass spectrometry data are reported from liquid chromatography-mass spectrometry (LC-MS). Chemical shifts for NMR data are expressed in parts per million (ppm, δ) referenced to residual peaks from the deuterated solvents used.

[0165] In syntheses referring to general procedures, reaction conditions (such as reaction length or temperature) may vary. Reactions were generally followed by thin layer chromatography or LC-MS and work-up as required. Purification may vary between experiments. Solvents and ratios of solvents used in eluents / gradients were generally chosen according to appropriate R f and / or retention times were selected to provide. Some products were purified using supercritical fluid chromatography on a reversed-phase column using, for example, a solvent combination of mobile phase A: CO2 and B: MeOH / H2O / NH3. Some compounds were purified using preparative HPLC, flash column chromatography, or a manual C18 reversed-phase column with H2O / MeCN polarity. EXAMPLES

The flask was evacuated three times and placed under an inert atmosphere. The mixture was cooled to -78°C and n-BuLi (7.59 mL, 19.0 mmol, 4.74 equiv) was added dropwise. The mixture was stirred at -78°C for 30 min, then transferred to an ice bath and stirred at 0°C for 45 min to give an orange solution. The mixture was again placed in a dry ice bath and tri-isopropyl borate (2.53 mL, 10.9 mmol) was added over 5 min using a syringe.
