Description

[0001] This application is a divisional application of the patent application with application number 201880044712.X, application date July 4, 2018, and name “Novel Sulfonamide Carboxamide Compounds”. Technical Field

[0002] The present invention relates to sulfonylureas and sulfonylthioureas comprising a non-aromatic heterocyclic group containing at least one ring nitrogen atom and further comprising a second cyclic group substituted at the alpha position, and to related salts, solvates, prodrugs, and pharmaceutical compositions. The present invention also relates to the use of such compounds in therapeutic agents for preventing medical conditions and diseases, most particularly for treating and preventing medical conditions and diseases by inhibiting NLRP3. Background Art

[0003] The NOD-like receptor (NLR) family, pyrin domain-containing protein 3 (NLRP3) inflammasome, is a component of the inflammatory process, and its aberrant activity is pathogenic in genetic disorders such as cryopyrin-associated periodic syndrome (CAPS) and complex diseases such as multiple sclerosis, type 2 diabetes, Alzheimer's disease, and atherosclerosis.

[0004] NLRP3 is an intracellular signaling molecule that senses many pathogen-derived, environmental, and host-derived factors. Upon activation, NLRP3 binds to apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (ASC). ASC then polymerizes to form large aggregates known as ASC specks. The polymerized ASC then interacts with the cysteine ​​protease caspase-1 to form a complex known as the inflammasome. This leads to the activation of caspase-1, which cleaves the precursor forms of the pro-inflammatory cytokines IL-1β and IL-18 (respectively, pro-IL-1β and pro-IL-18), thereby activating these cytokines. Caspase-1 also mediates a type of inflammatory cell death known as pyroptosis. ASC specks can also recruit and activate caspase-8, which processes pro-IL-1β and pro-IL-18 and triggers apoptotic cell death.

[0005] Caspase-1 cleaves pro-IL-1β and pro-IL-18 into their active forms, which are secreted out of the cell. Active caspase-1 also cleaves gasdermin-D to trigger pyroptosis. Although it controls the pyroptotic cell death pathway, caspase-1 also mediates the release of alarmin molecules such as IL-33 and high mobility group box 1 protein (HMGB1). Caspase-1 also cleaves intracellular IL-1R2, causing its degradation and allowing the release of IL-1α. In human cells, caspase-1 can also control the processing and secretion of IL-37. Many other caspase-1 substrates, such as components of the cellular backbone and glycolytic pathways, can lead to caspase-1-dependent inflammation.

[0006] NLRP3-dependent ASC specks are released into the extracellular milieu, where they activate caspase-1, induce processing of caspase-1 substrates, and propagate inflammation.

[0007] Active cytokines derived from NLRP3 inflammasome activation are important drivers of inflammation and interact with other cytokine pathways to shape immune responses to infection and injury. For example, IL-1β signaling induces the secretion of proinflammatory cytokines IL-6 and TNF. IL-1β and IL-18 collaborate with IL-23 to induce IL-17 production by memory CD4 Th17 cells and by γδ T cells in the absence of T cell receptor engagement. IL-18 and IL-12 also collaborate to induce IFN-γ production by memory T cells and NK cells that drive Th1 responses.

[0008] The inherited CAPS diseases Muckle-Wells syndrome (MWS), familial cold autoinflammatory syndrome (FCAS), and neonatal-onset multisystem inflammatory disease (NOMID) are caused by gain-of-function mutations in NLRP3, defining NLRP3 as a key component of the inflammatory process. NLRP3 has also been implicated in the pathogenesis of many complex diseases, including, in particular, metabolic disorders such as type 2 diabetes, atherosclerosis, obesity, and gout.

[0009] The role of NLRP3 in central nervous system diseases is emerging, and lung diseases have been shown to be affected by NLRP3. In addition, NLRP3 plays a role in the development of liver disease, kidney disease and aging. Many of these associations are linked using NLRP3. - / - Although the role of NLRP3 in type 2 diabetes (T2D) is well defined in mice, there is also an understanding of the specific activation of NLRP3 in these diseases. In type 2 diabetes (T2D), deposition of amylin in the pancreas activates NLRP3 and IL-1β signaling, leading to cell death and inflammation.

[0010] Several small molecules have been shown to inhibit the NLRP3 inflammasome. Glyburide inhibits IL-1β production at micromolar concentrations in response to activation of NLRP3, but not NLRC4 or NLRP1. Other previously characterized weak NLRP3 inhibitors include parthenolide, 3,4-methylenedioxy-β-nitrostyrene, and dimethyl sulfoxide (DMSO), but these agents have limited efficacy and are nonspecific.

[0011] Current treatments for NLRP3-related diseases include biologics targeting IL-1. These include the recombinant IL-1 receptor antagonist anakinra, the IL-1β-neutralizing antibody canakinumab, and the soluble decoy IL-1 receptor rilonacept. These approaches have proven successful in the treatment of CAPS, and these biologics have been used in clinical trials for other IL-1β-related diseases.

[0012] Some compounds containing diarylsulfonylureas have been identified as cytokine release inhibitory drugs (CRIDs) (Perregaux et al., J. Pharmacol. Exp. Ther. 299, 187-197, 2001). CRIDs are a class of compounds containing diarylsulfonylureas that inhibit the post-translational processing of IL-1β. Post-translational processing of IL-1β is accompanied by activation of caspase-1 and cell death. CRIDs block activated monocytes, rendering caspase-1 inactive and preserving plasma membrane latency.

[0013] Certain sulfonylurea-containing compounds have also been disclosed as inhibitors of NLRP3 (see, e.g., Baldwin et al., J. Med. Chem., 59(5), 1691-1710, 2016; and WO 2016 / 131098 A1, WO 2017 / 129897 A1, WO 2017 / 140778 A1, WO 2017 / 184604 A1, WO 2017 / 184623 A1, WO 2017 / 184624 A1, and WO 2018 / 015445 A1).

[0063] The term "halo" includes fluoro, chloro, bromo and iodo.

[0064] Unless otherwise stated, any reference to an element should be taken to include all isotopes of that element. Thus, for example, any reference to hydrogen should be taken to include all isotopes of hydrogen, including deuterium and tritium, unless otherwise stated.

[0065] When referring to a hydrocarbyl group or other group including one or more heteroatoms N, O and S in its carbon backbone, or when referring to a carbon atom of a hydrocarbyl group or other group replaced by an N, O or S atom, it is intended that:

[0066] Depend on replacement;

[0067] -CH2- is replaced by -NH-, -O- or -S-;

[0068] -CH3 is replaced by -NH2, -OH or -SH;

[0069] -CH= is replaced by -N=;

[0070] CH2= is replaced by NH=, O= or S=; or

[0071] CH≡ is replaced by N≡;

[0072] The proviso is that the resulting group contains at least one carbon atom. For example, methoxy, dimethylamino and aminoethyl groups are considered to be hydrocarbyl groups that include one or more heteroatoms N, O or S in their carbon backbone.

[0073] When referring to a hydrocarbon group or other group consisting of -N(O)(R β )-or-N + (R β )2- group in the main chain of the group replaced by the -CH2- group, it is intended that:

[0074] -CH2- by replacement; or

[0075] -CH2- by Replacement.

[0076] In the context of this specification, unless otherwise stated, C x -C y A radical is defined as a radical containing from x to y carbon atoms. For example, a C1-C4 alkyl radical is defined as an alkyl radical containing from 1 to 4 carbon atoms. When calculating the total number of carbon atoms in a parent radical substituted with optional substituents and / or containing optional moieties, the optional substituents and moieties are not taken into account. For the avoidance of doubt, when calculating C x -C y When counting the number of carbon atoms in a group, replacing heteroatoms such as N, O or S are not considered as carbon atoms. For example, a morpholinyl group is considered a C4 heterocyclic group, not a C6 heterocyclic group.

[0077] For the purposes of this specification, when a first atom or group is stated to be "directly bonded to" a second atom or group, it is understood that the first atom or group is covalently bonded to the second atom or group in the absence of one or more intervening atoms or groups. Thus, for example, for the group (C=O)N(CH3)2, the carbon atom of each methyl group is directly bonded to the nitrogen atom, and the carbon atom of the carbonyl group is directly bonded to the nitrogen atom, but the carbon atom of the carbonyl group is not directly bonded to the carbon atom of either methyl group.

[0078] R 1 For the avoidance of doubt, it should be noted that it is R that is directly attached to the sulfur atom of the sulfonylurea group (not any optional substituents). 1 A ring atom of a non-aromatic heterocyclic group.

[0079] R 1is a non-aromatic heterocyclic group which may be monocyclic, bicyclic (including bridged, fused and spiro), tricyclic or polycyclic. The bicyclic, tricyclic and polycyclic ring structures may be partially aromatic. For the avoidance of doubt, it should be noted that when R 1 When the sulfonylurea group is a partially aromatic bicyclic, tricyclic or polycyclic group, the R 1 For the avoidance of doubt, it should also be noted that when R 1 When it is a bicyclic, tricyclic or polycyclic group, R 1 The at least one ring nitrogen atom is in a non-aromatic ring, but not necessarily in the direct connection to the sulfur atom of the sulfonylurea group R 1 In one embodiment, when R 1 When it is a bicyclic, tricyclic or polycyclic group, R 1 The at least one ring nitrogen atom of R is directly connected to the sulfur atom of the sulfonylurea group 1 in the non-aromatic rings.

[0080] Usually, R 1 In one embodiment, R 1 is a 4-, 5-, 6- or 7-membered monocyclic ring or a 7-, 8-, 9- or 10-membered bicyclic ring, wherein R 1 In one embodiment, R 1 is a 4-, 5-, or 6-membered monocyclic ring or a 7-, 8-, 9-, or 10-membered bicyclic ring, wherein R 1 Optionally substituted.

[0082] In one embodiment, R 1 The non-aromatic heterocyclic group is monocyclic. 1 When the non-aromatic heterocyclic group is monocyclic, it may be optionally substituted with any monovalent substituent or any divalent π-bonded substituent (such as those defined above), but may not be substituted with a divalent bridging substituent (e.g., -O-, -S-, -NH-, -N(R β )-or-R α -) to form a bridged, fused, or spiro substituent. Examples of monocyclic non-aromatic heterocyclic groups include:

[0083]

[0084]

[0085] R1 The non-aromatic heterocyclic group may contain one or more double bonds in the heterocyclic ring, provided that the heterocyclic ring is non-aromatic. 1 The non-aromatic heterocyclic group does not have any tautomers that are aromatic.

[0086] The following aromatic heterocyclic groups are considered because they have aromatic tautomers:

[0087]

[0088] For the avoidance of doubt, the term "non-aromatic heterocyclic group" does not exclude heterocyclic groups or moieties that have aromatic character solely by virtue of meso charge separation. For example, consider the following non-aromatic heterocyclic group, as it has no aromatic tautomers:

[0089]

[0090] The last tautomer shown is not considered due to meso charge separation.

[0091] In one embodiment, R 1 The non-aromatic heterocyclic group is monocyclic and is selected from:

The resulting group may optionally be further substituted with any monovalent substituent or any divalent π-bonded substituent (such as those defined above). Typically in this embodiment, the resulting group is bicyclic or tricyclic, most typically bicyclic. Examples of such resulting bicyclic groups include:

[0096]

As used herein, the term "NLRP3 inhibition" refers to a complete or partial decrease in the level of NLRP3 activity and includes, for example, inhibition of active NLRP3 and / or inhibition of NLRP3 activation.

[0334] There is evidence that NLRP3-induced IL-1 and IL-18 play a role in the inflammatory response associated with or resulting from a number of different conditions (Menu et al., Clinical and Experimental Immunology, 166:1-15, 2011; Strowig et al., Nature, 481:278-286, 2012).

[0335] NLRP3 has been implicated in many autoinflammatory diseases, including familial Mediterranean fever (FMF), TNF receptor-associated periodic syndrome (TRAPS), hyperimmunoglobulinemia D and periodic fever syndrome (HIDS), septic arthritis, pyoderma gangrenosum, and acne (PAPA), Schweder's syndrome, chronic nonbacterial osteomyelitis (CNO), and acne vulgaris (Cook et al., Eur. J. Immunol., 40:595-653, 2010). In particular, NLRP3 mutations have been found to cause a group of rare autoinflammatory diseases called CAPS (Ozaki et al., J. Inflammation Research, 8:15-27, 2015; Schroder et al., Cell, 140:821-832, 2010; and Menu et al., Clinical and Experimental Immunology, 166:1-15, 2011). CAPS is a heritable disease characterized by recurrent fever and inflammation and includes three autoinflammatory disorders that form a clinical continuum. In order of increasing severity, these diseases are familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and chronic infantile neurocutaneous arthritis syndrome (CINCA; also known as neonatal-onset multisystem inflammatory disease, NOMID), and all have been shown to be caused by gain-of-function mutations in the NLRP3 gene, which result in increased IL-1β secretion.

[0336] NLRP3 has been implicated in a number of autoimmune diseases, including multiple sclerosis, type 1 diabetes (T1D), psoriasis, rheumatoid arthritis (RA), Behcet's disease, Schnitzler syndrome, macrophage activation syndrome (Masters Clin. Immunol. 2013; Braddock et al., at. Rev. Drug Disc. 2004 3:1-10; Inoue et al., Immunology 139:11-18; Coll et al., Nat. Med. 2015 21(3):248-55; and Scott et al., Clin. Exp. Rheumatol 2016 34(1):88-93), systemic lupus erythematosus (Lu et al., J Immunol. 2017; and Schnitzler et al., J Immunol. 2017). 198(3):1119-29) and systemic sclerosis (Artlett et al., Arthritis Rheum. 2011;63(11):3563-74). NLRP3 has also been shown to be involved in many lung diseases including chronic obstructive pulmonary disease (COPD), asthma (including steroid-resistant asthma), asbestosis, and silicosis (De Nardo et al., Am. J. Pathol., 184:42-54, 2014 and Kim et al., Am J Respir Crit Care Med. 2017 196(3):283-97). NLRP3 has also been suggested to play a role in many central nervous system conditions, including Parkinson's disease (PD), Alzheimer's disease (AD), dementia, Huntington's disease, cerebral malaria, brain damage caused by pneumococcal meningitis (Walsh et al., Nature Reviews, 15:84-97, 2014, and Dempsey et al., Brain. Behav. Immun. 2017 61:306-316), intracranial aneurysms (Zhang et al., J. Stroke & Cerebrovascular Dis. 2015 24;5:972-979), and traumatic brain injury (Ismael et al., J Neurotrauma. 2018 Jan 2).NRLP3 activity has also been shown to be involved in various metabolic diseases, including type 2 diabetes (T2D), atherosclerosis, obesity, gout, pseudogout, metabolic syndrome (Wen et al., Nature Immunology, 13:352-357, 2012; Duewell et al., Nature, 464:1357-1361, 2010; Strowig et al., Nature, 481:278-286, 2012), and non-alcoholic liver fibrosis (Mridha et al., J Hepatol. 2017 66(5):1037-46). NLRP3 has also been proposed to play a role in atherosclerosis, myocardial infarction (van Hout et al., Eur. Heart J 2017 38(11):828-36), heart failure (Sano et al., J AM. Coll. Cardiol. 2018 71(8):875-66), aortic aneurysm and dissection (Wu et al., Arterioscler. Thromb. Vasc. Biol. 2017 37(4):694-706), and other cardiovascular events (Ridker et al., NEngl J Med., doi:10.1056 / NEJMoa1707914, 2017) via IL-1β.Other diseases in which NLRP3 has been implicated include: ocular diseases such as wet and dry age-related macular degeneration (Doyle et al., Nature Medicine, 18:791-798, 2012 and Tarallo et al., Cell 2012 149(4):847-59), diabetic retinopathy (Loukovaara et al., Acta Ophthalmol. 2017;95(8):803-808), and optic nerve damage (Puyang et al., Sci Rep. 2016 Feb 19;6:20998); liver diseases, including nonalcoholic liver fibrosis (NASH) (Henao-Meija et al., Nature, 482:179-185, 2012); inflammatory responses in the lungs and skin (Primiano et al., J Ophthalmol. 2016;149(4):847-59); Immunol. 2016 197(6):2421-33), including contact allergies (such as bullous pemphigoid (Fang et al., J Dermatol Sci. 2016; 83(2):116-23), atopic dermatitis (Niebuhr et al., Allergy 2014 69(8):1058-67), hidradenitis suppurativa (Alikhan et al., 2009 J Am Acad Dermatol 60(4):539-61), acne vulgaris (Qin et al., J Invest. Dermatol. 2014 134(2):381-88) and sarcoidosis (Jager et al., Am J Respir Crit Care Med 2015 191:A5816); inflammatory responses in joints (Braddock et al., Nat. Rev. Drug 2015 191:A5816); Disc., 3:1-10, 2004); amyotrophic lateral sclerosis (Gugliandolo et al., Inflammation 2018 41(1):93-103); cystic fibrosis (Iannitti et al., Nat. Commun. 2016 7:10791); stroke (Walsh et al., Nature Reviews, 15:84-97, 2014); chronic kidney disease (Granata et al., PLoS One 2015 10(3):e0122272); and inflammatory bowel disease, including ulcerative colitis and Crohn's disease (Braddock et al., Nat. Rev. Drug Disc., 3:1-10, 2004, Neudecker et al., J Exp. Med. 2017 214(6):1737-52, and Lazaridis et al., Dig. Dis. Sci. 2017 62(9):2348-56).The NLRP3 inflammasome has been found to be activated in response to oxidative stress and UVB irradiation (Schroder et al., Science, 327:296-300, 2010). NLRP3 has also been shown to be involved in inflammatory hyperalgesia (Dolunay et al., Inflammation, 40:366-386, 2017).

[0337] The inflammasome, and NLRP3 in particular, has also been proposed to be a target of regulation by various pathogens, including viruses such as DNA viruses (Amsler et al., Future Virol. (2013) 8(4), 357-370).

[0338] NLRP3 has also been implicated in the pathogenesis of many cancers (Menu et al., Clinical and Experimental Immunology 166: 1-15, 2011; and Masters Clin. Immunol. 2013). For example, several previous studies have suggested a role for IL-1β in cancer invasiveness, growth, and metastasis, and inhibition of IL-1β with canakinumab reduced the incidence of lung cancer and overall cancer mortality in a randomized, double-blind, placebo-controlled trial (Ridker et al. Lancet, S0140-6736(17)32247-X, 2017). Inhibition of the NLRP3 inflammasome or IL-1β has also been shown to inhibit the proliferation and migration of lung cancer cells in vitro (Wang et al. Oncol Rep. 2016; 35(4): 2053-64). A role for the NLRP3 inflammasome has been suggested in myelodysplastic syndrome (Basiorka et al. Blood. 2016 Dec 22;128(25):2960-2975); and also in the carcinogenesis of various other cancers, including gliomas (Li et al. Am J Cancer Res. 2015;5(1):442-449), inflammation-induced tumors (Allen et al. J Exp Med. 2010;207(5):1045-56 and Hu et al. PNAS. 2010;107(50):21635-40), multiple myeloma (Li et al. Hematology 2016 21(3):144-51), and head and neck squamous cell carcinoma (Huang et al. J Exp Clin Cancer Res. 2017 2;36(1):116). It has also been shown that activation of the NLRP3 inflammasome mediates chemoresistance of tumor cells to 5-fluorouracil (Feng et al. J Exp Clin Cancer Res. 2017 21;36(1):81), and activation of the NLRP3 inflammasome in peripheral nerves leads to chemotherapy-induced neuropathic pain (Jia et al. Mol Pain. 2017;13:1-11).

[0339] NLRP3 has also been shown to be required for the effective control of infection by viral, bacterial, fungal, and helminthic pathogens (Strowig et al., Nature, 481:278-286, 2012).
