[0002] NLRP3 inflammasome inhibitors
[0003] FIELD OF THE DISCLOSURE
[0004] The present disclosure relates to novel 2,2-difluoro-benzo-dioxole derivatives that are useful as inhibitors of the NOD-like receptor protein 3 (NLRP3) inflammasome pathway. The present disclosure also relates to processes for the preparation of said compounds, pharmaceutical compositions comprising said compounds, methods of using said compounds in the treatment and diagnosis of various diseases and disorders mediated by NLRP3, and medicaments containing them.
[0005] BACKGROUND
[0006] The NOD-like receptor protein 3 (NLRP3) is a protein-coding gene: the protein belongs to the family of nucleotide-binding and oligomerization domain-like receptors (NLRs) and is also known as “pyrin domain-containing protein 3” (Inoue et al., Immunology, 2013, 139, 11-18). This gene encodes a protein containing a pyrin domain, a nucleotide-binding site domain (NBD), and a leucine-rich repeat (LRR) motif. In response to sterile inflammatory danger signals, NLRP3 interacts with an adapter protein, apoptosis-associated speck-like protein (ASC) and procaspase- 1 to form the NLRP3 inflammasome. NLRP3 inflammasome activation then leads to the release of the inflammatory cytokines I L-1 p (interleukin-1 P) and IL-18 (interleukin-18), and when dysregulated, can drive pathology in a number of disease settings.
[0007] NLRP3 inflammasome activation normally requires two steps. The first step involves a priming signal in which pathogen activated molecular patterns (PAMPs) or danger-activated molecular patterns (DAMPs) are recognized by Toll-like receptors, leading to activation of nuclear factor kappa B (NF-KB)-mediated signaling, which in turn up-regulates transcription of inflammasome-related components, including inactive NLRP3 and prolL-1 (pro-interleukin- 1 ) (Bauernfeind et al J. Immunol. 2009, 183, 787 - 791 ; Franchi et al Nat. Immunol. 2012, 13, 325 - 332, Franchi et al J. Immunol. 2014, 193, 4214 - 4222). The second step is the oligomerization of NLRP3 and subsequent assembly of NLRP3, ASC, and procaspase-1 into an inflammasome complex. This triggers the transformation of procaspase-1 to caspase-1 , and the production and secretion of mature IL-1 p and IL-18 (Kim et al J. Inflamm. 2015, 12, 41 ; Ozaki et al J. Inflamm. Res. 2015, 8, 15 - 27; Rabeony et al. Eur. J. Immunol. 2015, 45, 2847 - 2857).
[0008] NLRP3 inflammasome activation has been linked to various inflammasome-related diseases I disorders, immune diseases, inflammatory diseases, auto-immune diseases and auto- inflammatory diseases, for example, autoinflam matory fever syndrome such as cryopyrin- PAT059896-PCT-SEC01 -2- associated periodic syndrome (CAPS) (Mortimer et al Nature Immunol. 2016, 17(10), 1176- 1188); sickle cell disease; systemic lupus erythematosus (SLE); liver related diseases I disorders such as chronic liver disease, viral hepatitis, non-alcoholic steatohepatitis (NASH), alcoholic steatohepatitis, and alcoholic liver disease (Petrasek et al J. Clin. Invest. 2012, 122, 3476-89; Petrasek et al. Nat. Rev. Gastroenterol. Hepatol. 2015, 12, 387-400; Mridha et al J. Hepatol. 2017, 66, 1037-46); inflammatory arthritis related disorders, such as gout, pseudogout (chondrocalcinosis), osteoarthritis (Ridker et al N. Engl. J. Med. 2017, 377, 1119- 31), and rheumatoid arthritis (Mathews et al Ann. Rheum. Dis. 2014, 73, 1202-10), acute or chronic arthropathy; kidney related diseases such as hyperoxaluria (Knauf et al. Kidney Int. 2013, 84, 895-901), lupus nephritis, hypertensive nephropathy (Krishnan et al Br. J. Pharmacol. 2016, 173, 752-65), hemodialysis related inflammation and diabetic nephropathy which is a kidney-related complication of diabetes (Type 1 , Type 2 and mellitus diabetes), also called diabetic kidney disease (Shahzad et al Kidney Int. 2015, 87, 74-84). Emerging studies have revealed the involvement of the increased production of I L-1 and IL-18 by the NLRP3 inflammasome can contribute to the onset and progression of various diseases such as neuroinflammation-related disorders, e.g. brain infection, acute injury, multiple sclerosis, Alzheimer’s disease, and neurodegenerative diseases (Shao et al. Front. Pharmacol. 2015, 6, 262); cardiovascular / metabolic disorders I diseases, e.g. cardiovascular risk reduction (CvRR), atherosclerosis, type I and type II diabetes and related complications (e.g. nephropathy, retinopathy), peripheral artery disease (PAD), acute heart failure and hypertension (Ridker et al N. Engl. J. Med. 2017, 377, 1119-31 ; Vandanmasgar et al Nat. Med. 2011 , 17, 179-88; Hu et al Proc. Natl. Acad. Sci. 2015, 112, 11318-23; Antonopoulos et al Curr. Opin. Pharmacol. 2017, 39, 1-8; Toldo S et al Nat. Rev. Cardiol. 2018, 15, 203-214); wound healing and scar formation; inflammatory skin diseases, e.g. acne, hidradenitis suppurativa (Sweeney et al Br. J. Dermatol. 2015, 173, 1361), asthma, sarcoidosis, age- related macular degeneration; cancer related diseases I disorders, e.g. myeloproliferative neoplasms, leukemias, myelodysplastic syndromes (MDS), myelofibrosis, lung cancer, colon cancer (Ridker et al Lancet 2017, 390, 1833-42; Derangere et al Cell. Death Differ. 2014, 21 , 1914-24, Gelfo et al Oncotarget 201Q, 7, 72167-83, Baiorka et al Blood 2016, 128, 2960-75; Carey et al Cell. Rep. 2017, 18, 3204-18). Those diseases I disorders that are immune or inflammatory in nature usually are difficult to diagnose or treat efficiently. Most treatments include treating of the symptoms, slowing down the progression of the disease I disorder, change in lifestyle and surgery as a last resort (e.g., open heart surgery for advance forms of atherosclerosis). Recent studies have linked mitochondrial dysfunction and NLRP3 activation in neuroinflammation related diseases such as Parkinson’s (Sarkar et al npj Parkinson’s disease 2017, 3:30; Zhou et al Nature, 2011 , 469, 221). One of the major problems associated with the mitochondrial modulators is their poor metabolic stability; thus there is a PAT059896-PCT-SEC01 -3- need for selective and stable inhibitors in neuroinflammation of this nature (Lee et al EurJ.
[0009] Org. Chem. 2017, 141 , 240).
[0010] Therefore, there is a need for inhibitors of the NLRP3 inflammasome pathway to provide new and / or alternative treatments for these inflammasome-related diseases I disorders and others such as autoinflammatory fever syndrome cryopyrin-associated periodic syndrome {e.g. CAPS), sickle cell disease, chronic liver disease, nonalcoholic steatohepatitis (NASH), gout, hyperoxaluria, secondary hyperoxaluria, pseudogout (chondrocalcinosis), Type I / Type II diabetes and related complications (e.g. nephropathy, retinopathy), neuroinflammation-related disorders (e.g. multiple sclerosis, brain infection, acute injury, neurodegenerative diseases, Alzheimer’s disease), atherosclerosis and cardiovascular risk (e.g. cardiovascular risk reduction (CvRR), hypertension), hidradenitis suppurativa, wound healing and scar formation, and cancer (e.g. colon cancer, lung cancer, myeloproliferative neoplasms, leukemias, myelodysplastic syndromes (MDS), myelofibrosis).
[0011] WO2020 / 234715 describes pyridazin-3-yl phenol compounds as NLRP3 inflammasome inhibitors. WO2021 / 193897 describes substituted pyridazine compounds as NLRP3 inflammasome inhibitors. WO2022 / 135567 describes pyridazine containing compounds as NLRP3 inflammasome inhibitors. WO2024 / 145623 describes heterocyclic and heteroaryl compounds as inhibitors of NLRP3.

[0107] Depending on the choice of the starting materials and procedures, the compounds can be present in the form of one of the possible stereoisomers or as mixtures thereof, for example as pure optical isomers, or as stereoisomer mixtures, such as racemates and diastereoisomer mixtures, depending on the number of asymmetric carbon atoms. The present disclosure is meant to include all such possible stereoisomers, including racemic mixtures, diastereoisomeric mixtures, and optically pure forms. Optically active (R)- and (S)- stereoisomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may have a cis- or trans-configuration. All tautomeric forms are also intended to be included. The disclosure is also meant to include any pseudo-asymmetric carbon atom, represented herein as (R)- and (S)-, and which are invariant on reflection in a mirror but are reversed by exchange of any two entities, (PAC 1996, 68, 2193, Basic terminology of stereochemistry IUPAC recommandations 1996).
[0108] As used herein, the terms “salt” or “salts” refers to an acid addition or base addition salt of a compound of the disclosure. “Salts” include in particular “pharmaceutical acceptable salts”. The term “pharmaceutically acceptable salts” refers to salts that retain the biological effectiveness and properties of the compounds of this disclosure and, which typically are not biologically or otherwise undesirable. In many cases, the compounds of the present disclosure are capable of forming acid and I or base salts by virtue of the presence of amino and I or carboxyl groups, or groups similar thereto.
[0109] Pharmaceutically acceptable acid addition salts can be formed with inorganic acids and organic acids.
[0110] Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like.
[0111] Organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, toluenesulfonic acid, sulfosalicylic acid, and the like.
[0112] Pharmaceutically acceptable base addition salts can be formed with inorganic and organic bases. PAT059896-PCT-SEC01 -15-
[0113] Inorganic bases from which salts can be derived include, for example, ammonium salts and metals from columns I to XII of the periodic table. In certain embodiments, the salts are derived from sodium, potassium, ammonium, calcium, magnesium, iron, silver, zinc, and copper; particularly suitable salts include ammonium, potassium, sodium, calcium and magnesium salts.
[0114] Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like.

[0117] Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulae given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Isotopes that can be incorporated into compounds of the disclosure include, for example, isotopes of hydrogen. PAT059896-PCT-SEC01 -16-
[0118] Further, incorporation of certain isotopes, particularly deuterium (i.e.,2H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements or an improvement in therapeutic index or tolerability. It is understood that deuterium in this context is regarded as a substituent of a compound of formula (I). The concentration of deuterium, may be defined by the isotopic enrichment factor. The term "isotopic enrichment factor" as used herein means the ratio between the isotopic abundance and the natural abundance of a specified isotope. If a substituent in a compound of this disclosure is denoted as being deuterium, such compound has an isotopic enrichment factor for each designated deuterium atom of at least 3500 (52.5% deuterium incorporation at each designated deuterium atom), at least 4000 (60% deuterium incorporation), at least 4500 (67.5% deuterium incorporation), at least 5000 (75% deuterium incorporation), at least 5500 (82.5% deuterium incorporation), at least 6000 (90% deuterium incorporation), at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation), at least 6600 (99% deuterium incorporation), or at least 6633.3 (99.5% deuterium incorporation). It should be understood that the term “isotopic enrichment factor” can be applied to any isotope in the same manner as described for deuterium.
[0119] Further examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, and chlorine, such as2H,3H,11C,13C,14C,15N,18F,31P,32P,35S,36CI,125l respectively. The disclosure includes various isotopically labeled compounds as defined herein, for example those into which radioactive isotopes, such as3H and14C, or those into which non-radioactive isotopes, such as2H and13C are present. Such isotopically labelled compounds are useful in metabolic studies (with14C), reaction kinetic studies (with, for example2H or3H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an18F or125l labeled compound may be particularly desirable for PET or SPECT studies. Isotopically labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using an appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed.

[0143] METHOD OF USE
[0144] There is evidence for a role of NLRP3-induced IL-1 and IL-18 in the inflammatory responses occurring in connection with, or as a result of, a multitude of different disorders (Menu et al, Clinical and Experimental Immunology, 2011 , 166, 1-15; Strowig et al, Nature, 2012, 481 , PAT059896-PCT-SEC01 -23-
[0145] 278-286). NLRP3 mutations have been found to be responsible for a set of rare autoinflammatory diseases known as CAPS (Ozaki et al, J. Inflammation Research, 2015, 8,15-27; Schroder et al, Cell, 2010, 140: 821-832; Menu et al, Clinical and Experimental Immunology, 2011 , 166, 1-15). CAPS are heritable diseases characterized by recurrent fever and inflammation and are comprised of three autoinflammatory disorders that form a clinical continuum. These diseases, in order of increasing severity, are familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and chronic infantile cutaneous neurological articular syndrome (CINCA; also called neonatal-onset multisystem inflammatory disease, NOMID), and all have been shown to result from gain-of-function mutations in the NLRP3 gene, which leads to increased secretion of I L-1 p. NLRP3 has also been implicated in a number of autoinflammatory diseases, including pyogenic arthritis, pyoderma gangrenosum and acne (PAPA), Sweet's syndrome, chronic nonbacterial osteomyelitis (CNO), and acne vulgaris (Cook et al, Eur. J. Immunol., 2010, 40, 595-653).
[0146] A number of autoimmune diseases have been shown to involve NLRP3 including, in particular, multiple sclerosis, type-1 diabetes (T1 D), psoriasis, rheumatoid arthritis (RA), Behcet's disease, Schnitzler syndrome, macrophage activation syndrome (Braddock et al. Nat. Rev. Drug Disc. 2004, 3, 1-10; Inoue et al., Immunology, 2013, 139, 11-18, Coll et al, Nat. Med. 2015, 21 (3), 248-55; Scott et al, Clin. Exp. Rheumatol. 2016, 34(1), 88-93), systemic lupus erythematosus and its complications such as lupus nephritis (Lu 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 play a role in a number of lung diseases including chronic obstructive pulmonary disorder (COPD), asthma (including steroid-resistant asthma), asbestosis, and silicosis (De Nardo et al, Am. J. Pathol., 2014, 184: 42-54; Kim et al. Am. J. Respir. Crit. Care Med, 2017, 196(3), 283-97). NLRP3 has also been suggested to have a role in a number of central nervous system conditions, including Multiple Sclerosis (MS), Parkinson's disease (PD), Alzheimer's disease (AD), dementia, Huntington's disease, cerebral malaria, brain injury from pneumococcal meningitis (Walsh et al, Nature Reviews, 2014, 15, 84-97; and Dempsey et al. Brain. Behav. Immun. 2017, 61 , 306-16), intracranial aneurysms (Zhang et al. J. Stroke and Cerebrovascular Dis., 2015, 24, 5, 972-9), and traumatic brain injury (Ismael et al. J. Neurotrauma., 2018, 35(11), 1294-1303). NRLP3 activity has also been shown to be involved in various metabolic diseases including type 2 diabetes (T2D) and its organ-specific complications, atherosclerosis, obesity, gout, pseudogout, metabolic syndrome (Wen et al, Nature Immunology, 2012, 13, 352-357; Duewell et al, Nature, 2010, 464, 1357-1361 ; Strowig et al, Nature, 2014, 481 , 278- 286), and non-alcoholic steatohepatitis (Mridha et al. J. Hepatol. 2017, 66(5), 1037-46). A role for NLRP3 via IL-1 beta has also been suggested in atherosclerosis, myocardial infarction (van Hout et al. Eur. Heart PAT059896-PCT-SEC01 -24-
[0147] 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. Vase. Biol., 2017,37(4), 694- 706), and other cardiovascular events (Ridker et al., N. Engl. J. Med., 2017, 377(12), 1119- 31).
[0148] Other diseases in which NLRP3 has been shown to be involved include: ocular diseases such as both wet and dry age-related macular degeneration (Doyle et al. Nature Medicine, 2012, 18, 791-798; Tarallo et al. Ce / / 2012, 149(4), 847-59), diabetic retinopathy (Loukovaara et al. Acta Ophthalmol., 2017, 95(8), 803-8), non-infectious uveitis and optic nerve damage (Puyang et al. Sci. Rep. 2016, 6, 20998); liver diseases including non-alcoholic steatohepatitis (NASH) and acute alcoholic hepatitis (Henao-Meija et al, Nature, 2012, 482, 179-185); inflammatory reactions in the lung and skin (Primiano et al. J. Immunol. 2016, 197(6), 2421- 33) including contact hypersensitivity (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. J. Am. Acad. Dermatol., 2009 ,60(4), 539-61), and sarcoidosis (Jager et al. Am. J. Respir. Crit. Care Med., 2015, 191, A5816); inflammatory reactions in the joints (Braddock et al, Nat. Rev. Drug Disc, 2004, 3, 1-10); amyotrophic lateral sclerosis (Gugliandolo et al. Int. J. Mol. Sci., 2018, 19(7), E1992); cystic fibrosis (lannitti et al. Nat. Commun., 2016, 7, 10791); stroke (Walsh et al, Nature Reviews, 2014, 15, 84-97); chronic kidney disease (Granata et al. PLoS One 2015, 10(3), eoi22272); and inflammatory bowel diseases including ulcerative colitis and Crohn's disease (Braddock et al., Nat. Rev. Drug Disc, 2004, 3, 1-10; Neudecker et al. J. Exp. Med. 2017, 214(6), 1737-52; 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. NLRP3 has also been shown to be involved in inflammatory hyperalgesia (Dolunay et al, Inflammation, 2017, 40, 366-86).
[0149] Activation of the NLRP3 inflammasome has been shown to potentiate some pathogenic infections such as influenza and Leishmaniasis (Tate et al., Sci Rep., 2016, 10(6), 27912-20; Novias et al., PLOS Pathogens 2017, 13(2), e1006196).
[0150] NLRP3 has also been implicated in the pathogenesis of many cancers (Menu et al, Clinical and Experimental Immunology, 2011, 166, 1-15). For example, several previous studies have suggested a role for IL-1 beta in cancer invasiveness, growth and metastasis, and inhibition of IL-1 beta with canakinumab has been shown to reduce the incidence of lung cancer and total cancer mortality in a randomised, double-blind, placebo-controlled trial (Ridker et al. Lancet., 2017, 390(10105), 1833-42). Inhibition of the NLRP3 inflammasome or IL-1 beta has also been shown to inhibit the proliferation and migration of lung cancer cells in vitro (Wang et al. PAT059896-PCT-SEC01 -25-
[0151] Oncol Rep., 2016, 35(4), 2053-64). A role for the NLRP3 inflammasome has been suggested in myelodysplastic syndromes, myelofibrosis and other myeloproliferative neoplasms, and acute myeloid leukemia (AML) (Basiorka et al. Blood, 2016, 128(25), 2960-75.) and also in the carcinogenesis of various other cancers including glioma (Li et al. Am. J. Cancer Res.
[0152] 2015, 5(1), 442-9), inflammation- induced tumors (Allen et al. J. Exp. Med. 2010, 207(5), 1045-56; Hu et al. PNAS., 2010, 107(50), 21635-40), multiple myeloma (Li et al. Hematology, 2016 21(3), 144-51), and squamous cell carcinoma of the head and neck (Huang et al. J. Exp. Clin. Cancer Res., 2017, 36(1), 116). Activation of the NLRP3 inflammasome has also been shown to mediate chemoresistance of tumor cells to 5-Fluorouracil (Feng et al. J. Exp. Clin. Cancer Res., 2017, 36(1), 81), and activation of NLRP3 inflammasome in peripheral nerve contributes to chemotherapy-induced neuropathic pain (Jia et al. Mol. Pain., 2017, 13, 1-11). NLRP3 has also been shown to be required for the efficient control of viruses, bacteria, and fungi.
[0153] The activation of NLRP3 leads to cell pyroptosis and this feature plays an important part in the manifestation of clinical disease (Yan-gang et al., Cell Death and Disease, 2017, 8(2), 2579; Alexander et al., Hepatology, 2014, 59(3), 898-910; Baldwin et al., J. Med. Chem.,
[0154] 2016, 59(5), 1691- 1710; Ozaki et al., J. Inflammation Research, 2015, 8, 15-27; Zhen et al., Neuroimmunology Neuroinflammation, 2014, 1(2), 60-65; Mattia et al., J. Med. Chem., 2014, 57(24), 10366-82; Satoh et al., Cell Death and Disease, 2013, 4, 644). Therefore, it is anticipated that inhibitors of NLRP3 will block pyroptosis, as well as the release of pro- inflammatory cytokines (e.g. IL-1 beta) from the cell.

Cells were differentiated in bulk with 0.5 pM phorbol 12-myristate 13-acetate (PMA; Sigma # P8139) for 3 h, media was exchanged, and cells were plated at 50,000 cells per well in a 384-well flat-bottom cell culture plates (Greiner, #781986), and allowed to differentiate overnight. Compound in a 1 :3.16 serial dilution series in DMSO was added 1 :100 to the cells and incubated for 1 h. The NLRP3 inflammasome was activated with the addition of 15 pM (final concentration) Nigericin (Enzo Life Sciences, #BML- CA421-0005), and cells were incubated for 3 h. 10 pL supernatant was removed, and IL-10 levels were monitored using an HTRF (Homogeneous Time Resolved Fluorescence) assay (CisBio, #62IL1 PEC) according to manufacturers’ instructions. Viability and pyroptosis was monitored with the addition of PrestoBlue cell viability reagent (Life Technologies, #A13261) directly to the cell culture plate.
[0438] TNF-a secretion assay:
[0439] Monocytic THP-1 cells were maintained according to providers’ instructions in RPMI media as described above. Undifferentiated cells were plated at 50,000 cells per well in a 384-well flatbottom cell culture plates (Greiner, #781986), and allowed to rest overnight. Experimental compounds were prepared and added as described above. TNF-a secretion was triggered by the addition of either 1 pg / mL LPS (Sigma, #L4391) or 100 ng / mL Pam3CSK4 (Invivogen, #tlrl- pms) depending on the experiment, and cells were incubated for 3 h. 10 pL supernatant was removed, and TNF-a levels were monitored using an HTRF assay (CisBio, #62TNFPEC) according to manufacturers’ instructions.

The curve fitting was conducted with an internally developed software suite.
[0442] NLRP3-dependent IL-ip secretion was stimulated in PMA-differentiated THP-1 cells by the addition of nigericin, and cytokines were measured in the serum after 3 h. As discussed above, activation of the NLRP3 inflammasome requires both an NF-kB-dependent priming step and the addition of a NLRP3 activator. To ensure that the inhibitors did not interfere with the priming step, Pam3CSK4-stimulated, NF-kB-dependent TNF-a secretion was monitored as a counter screen. Data for the inhibitory effect (IC50) of the compounds of the disclosure for both assays are given in the table below. Data for I L-1 p secretion was calculated as the geometric mean of at least 3 individual experiments, TNF-a data was from either one or two individual experiments.
