Abstract
Description
Background of the Invention NLRP3 is a member of the nucleotide-binding domain (NBD), leucine-rich repeat (LRR) (NLR) protein family that mediates innate inflammatory processes following infection or tissue damage. Upon activation, it forms an inflammasome complex with ASC and caspase-1, leading to the release of IL-1β and IL-18 and pyroptosis.
[0002] The pathological function of NLRP3-mediated inflammation has been described in genetic diseases (such as cryoinflammatory-associated periodic syndrome (CAPS)) as well as chronic inflammatory diseases (such as rheumatoid arthritis), metabolic diseases (such as diabetes) or neurological diseases (such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis).
[0003] NLRP3 is an intracellular sensor molecule that is activated in two steps: initiation and activation. The initiation step involves stimulation of pattern recognition receptors (PRRs), such as Toll-like receptors, and activation of the nuclear factor-κB (NFκB) pathway, which increases the expression of NLRP3, caspase-1, quercetin D, and pro-inflammatory cytokines. The NLRP3 activation step leads to the formation of active inflammasomes, which can be triggered by bacterial, viral, and fungal infections (PAMP; pathogen-associated molecular patterns; e.g., nigericin, DNA, RNA), aseptic inflammation mediated by endogenous molecules (DAMP; damage-associated molecular patterns; e.g., ATP, cholesterol crystals, α-synuclein, amyloid-β), and exposure to environmental stimuli (Swanson et al., Nature Review Immunology, 2019, Vol 19, 477–489).
[0004] PAMP and DAMP induce cellular stress, which is sensed by NLRP3. Many of them activate NLRP3 by leading to a decrease in cytoplasmic potassium ions, thereby inducing a conformational change in inactive NLRP3 protein, resulting in the formation of the NLRP3 complex, which recruits ASC (a CARD-containing adaptor protein, apoptosis-associated speckle-like protein). ASC binds to its precursor, caspase-1, which is activated within the multiprotein inflammasome complex (also known as the ASC speckle). Active caspase-1 cleaves the pro-inflammatory cytokines IL-1β and IL-18, as well as GSDMD (apoptosis-derived cytokinase D), which forms pores within the membrane, allowing the release of mature IL-1β and IL-18 and triggering pyroptosis. During pyroptosis, the release of intracellular contents (including the NLRP3 inflammasome, high-mobility group box 1 (HMGB1), leukotrienes, and prostaglandins) amplifies the inflammatory response and promotes inflammatory pathology (Mangan et al., Nature Reviews Drug Discovery, 2018, Vol. 17, 588-606; Swanson et al., Nature Review Immunology, 2019, Vol 19, 477–489).
[0005] The pathological consequence of NLRP3 activation has been observed in patients carrying inherited autosomal dominant mutations in NLRP3, which promote the activation of the NLRP3 inflammasome. Patients with these gain-of-function mutations suffer from a rare systemic autoinflammatory syndrome called cold inflammatory-associated periodic syndrome (CAPS), characterized by an inflammation-associated phenotype with periodic fever, aseptic urticaria, and joint inflammation. CAPS comprises three overlapping disease entities: familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal episodic multisystem autoinflammatory syndrome (NOMID).
[0006] Preclinical studies of NLRP3 gene deletion or small molecule inhibitors have linked NLRP3-mediated inflammation to many peripheral and central nervous system diseases. These include chronic inflammatory diseases, including gout, rheumatoid arthritis, and inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis; metabolic diseases, such as atherosclerosis, diabetes, metabolic syndrome, obesity and hepatic steatosis, non-alcoholic steatohepatitis (NASH), and liver fibrosis; and neurological diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD), multiple sclerosis (MS), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), prions, traumatic brain injury (TBI), and stroke; as well as asthma and allergic airway inflammation, hypertension, myocardial infarction, excessive inflammation following influenza and / or severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), graft-versus-host disease, silicosis, myelodysplastic syndromes, contact hypersensitivity reactions, and joint inflammation triggered by chikungunya virus (Mangan et al., Nature Reviews Drug Discovery, 2018, Vol. 17, 588-606; Holbrook et al., Frontiers in Pharmacology , 2021, Vol. 12, Article 643254; Coll et al., Trends in Pharmacological Science , 2022, Vol. 43, 653-668; Thornton et al., Journal of Pharmacology and Experimental Therapeutics , March 2024, 388(3) 813-826).
[0007] Several small molecules have been reported to directly or indirectly inhibit NLRP3. They exhibit weak potency and / or off-target effects in the micromolar range (Coll et al., Trends in Pharmacological Science, 2022, Vol. 43, 653-668). MCC950 has been used as a tool compound in many preclinical studies, demonstrating good potency and selectivity exceeding that of NLRC4 and NLRP1. However, high doses in clinical studies have resulted in hepatotoxicity (Mangan et al., Nature Reviews Drug Discovery, 2018, Vol. 17, 588-606).
[0008] The pro-inflammatory cytokine IL-1β is a potent NLRP3-dependent effector and therefore a major target for limiting NLRP3-driven pathologies. Biologics such as anakinin, cannabidiol, and linacip, which inhibit the IL1 axis, have been approved for the treatment of CAPS and are being tested in clinical trials for rheumatoid arthritis and gout. However, biologics require injection, which causes inflammation at the injection site and has poor brain penetration (Mangan et al., Nature Reviews DrugDiscovery, 2018, Vol. 17, 588-606).
[0009] There is a need for orally available, preferably brain-penetrating, NLRP3 inhibitors with improved potency and selectivity.

[0074] When tautomerism (e.g., keto-enol tautomerism) is possible in compounds of formula (I), each form (e.g., ketone and enol forms) is included individually or in mixtures in any proportion. This also applies to stereoisomers, such as enantiomers, cis / trans isomers, conformational isomers, etc.
[0075] In particular, when a compound according to formula (I) is given as an enantiomer or diastereomer, each pure form alone and any mixture of at least two pure forms in any proportion are included in formula (I) and are the subject of this invention.
[0076] Isotope-labeled compounds of formula (I) are also within the scope of this invention. Isotope labeling methods are known in the art. Preferred isotopes are isotopes of the elements H, C, N, O, and S. Therefore, compounds containing one or more of these is also particularly covered. 2 The compounds of this invention are hydrogen in the form of H / deuterium. Solvents and hydrates of compounds of formula (I) are also within the scope of this invention.
[0077] If necessary, isomers can be separated using methods well known in the art, such as liquid chromatography. The same applies to enantiomers, which can be separated using, for example, a chiral stationary phase. Alternatively, enantiomers can be separated by converting the enantiomer to a diastereomer, i.e., by coupling it with an enantiomerically pure auxiliary compound, followed by separation of the resulting diastereomer and cleavage of the auxiliary residues. Alternatively, any enantiomer of the compound of formula (I) can be obtained by stereoselective synthesis using optically pure starting materials, reagents, and / or catalysts.
[0078] If a compound according to formula (I) contains one or more acidic or basic groups, the invention also includes its corresponding pharmaceutically or toxicologically acceptable salt, particularly its pharmaceutically usable salt. Thus, compounds of formula (I) containing acidic groups can, according to the invention, be used, for example, as alkali metal salts, alkaline earth metal salts, or ammonium salts. More precisely, examples of such salts include sodium, potassium, calcium, magnesium salts, or salts with ammonia or organic amines (e.g., ethylamine, ethanolamine, triethanolamine, or amino acids). Compounds of formula (I) containing one or more basic groups (i.e., groups that can be protonated) can be present and can be used according to the invention as addition salts of inorganic or organic acids. Examples of suitable acids include hydrogen chloride, hydrogen bromide, phosphoric acid, sulfuric acid, nitric acid, methanesulfonic acid, p-toluenesulfonic acid, naphthalenedisulfonic acid, oxalic acid, acetic acid, tartaric acid, lactic acid, salicylic acid, benzoic acid, formic acid, propionic acid, neopentanoic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, malic acid, aminosulfonic acid, phenylpropionic acid, gluconic acid, ascorbic acid, isonicotinic acid, citric acid, adipic acid, and other acids known to those skilled in the art. If the compound of formula (I) contains both acidic and basic groups in its molecule, the invention also includes, in addition to the salt forms mentioned, internal salts or betaine (zwitterions). The corresponding salts according to formula (I) can be obtained by conventional methods known to those skilled in the art, for example, by contacting them with organic or inorganic acids or bases in a solvent or dispersant, or by anion or cation exchange with other salts. The present invention also includes all salts of compounds of formula (I), which are not directly applicable to pharmaceuticals due to low physiological compatibility, but may be used, for example, as intermediates in chemical reactions or for the preparation of pharmaceutically acceptable salts.

In short, 8 µl of supernatant and 2 µl of premixed anti-IL1β-Crypta antibody and anti-IL1β-XL antibody were added to a 384-well plate (Greiner BioOne), incubated at room temperature for 24 hours, and measured using a Pherastar FSX reader (BMG LabTech) at excitation wavelength of 337 nm (donor) and emission wavelengths of 620 / 665 nm (acceptor).
[0169] The HTRF ratio between donor and recipient signals was calculated and normalized with high and low controls to calculate IC50. 50 Value (nM). NLRP3 inhibitors reduce LPS / nigrain-induced IL-1β release, which manifests as a decrease in the HTRF ratio.
[0170] Table 23 shows the THP1 IL-1β release of the tested example compounds.
