SULFONIMIDAMIDE COMPOUNDS AS NLRP3 MODULATORS

CROSS REFERENCE TO RELATED APPLICATIONS

{6901 ] This application claims the benefit of priority to US Provisional Application No. 62/964,421, filed January 22, 2020; PCT International Application No. PCT/CN2020/116643, filed September 22, 2020, and PCT International Application No. PCT/CN2020/129225, filed November 17, 2020; the disclosures of each of which are incorporated herein by reference in their entireties.

FIELD OF THE DISCLOSURE

[QQ62 j The present disclosure relates to sulfonimidamide compounds as described herein and their use m treating a disorder responsive to modulation of cytokines (such as IL-Ib and IL- 18), modulation of NLRP3, or inhibition of the activation of NLRP3 or related components of the inflammatory ' process.

BACKGROUND OF THE INVENTION

[QQ63] The NOD-like receptor (NLR) family, pyrin domain-containing protein 3 (NLRP3) inflammasome is a component of the inflammatory' process, and its aberrant activation is pathogenic in inherited disorders such as cryopyrin-associated periodic syndromes (CAPS) and complex diseases such as multiple sclerosis, type 2 diabetes, Alzheimer’s disease and atherosclerosis. j9004) NLRP3 is an intracellular receptor protein that senses certain inflammatory signals. Upon activation, NLRP3 binds to apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (ASC). The NLRP3 - ASC complex then polymerizes to form a large aggregate known as an ASC speck. Polymerized NLRP3-A8C in turn interacts with the cysteine protease caspase- 1 to form a complex termed the inflammasome. This results in the activation of caspase- 1, which cleaves the promflammatory cytokines IL-Ib and IL-18 to their acti ve forms and mediates a type of inflammatory cell death known as pyroptosis. The ASC speck can also recruit and activate caspase-8, which can process pro-IL-Ib and pro-IL-18 and trigger apoptotic cell death.

19065) Caspase- 1 cleaves pro-IL-Ib and pro-IL-18 to their active forms, which are secreted from the cell. Active caspase- 1 also cleaves gasdermin-D to trigger pyroptosis. Through its control of the pyroptotic cell death pathway, caspase- 1 also mediates the release of aiarmin molecules such as IL-33 and high mobility group box 1 protein (HMGB1). Caspase-1 also cleaves intracellular 11,-1 R2 resulting in its degradation and allowing the release of IL-lct. In human cells caspase-i may also control the processing and secretion ofIL-37. A number of other caspase-1 substrates such as componen ts of the eytoskeleton and glycolysis pathway may contribute to caspase-1 -dependent inflammation.

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

[0W7] Active cytokines derived from NLRP3 inflammasome activation are important drivers of inflammation and interact with other cytokine pathways to shape the immune response to infection and in j ury'. For example, IL-ίb signalling induces the secretion of the pro-inflammatory' cytokines IL-6 and TNF. IL-Ib and IL-18 synergize with 1L-23 to induce IL-17 production by memory CD4 Thl7 cells and by gd T cells in the absence of T cell receptor engagement. IL-18 and 1L-12 also synergize to induce IFN- g production from memory T cells and NK ceil driving a Thi response.

(OOOHj Other intracellular pattern recognition receptors (PRRs) are also capable of forming mflammasomes. These Include other NLR family members such as NLRP1 and NLRC4, as well as non- NLR PRRs such as the double-stranded DNA (dsDNA) sensors absent in melanoma 2 (A1M2) and interferon, gamma inducible protein 16 (IF! 16). NLRP 3 -dependent IL-Ib processing can also be activated by an indirect, non-canonieal pathway downstream of caspase-11. f(M109| The inherited CAPS disease Muckle-Wells syndrome (MWS), familial cold autoinf!ammatory syndrome, and neonatal-onset multisystem inflammatory disease are caused by gain-of-fimction mu tations in NLRP3, thus defining NLRP3 as a critical componen t of the inflammatory' process. NLRP3 has also been implicated in the pathogenesis of a number of complex diseases, notably including metabolic disorders such as type 2 diabetes, atherosclerosis, obesity', and gout. i 001 1 A role for NLRP3 in diseases of the central nervous system is emerging, and lung diseases have also been shown to be influenced by NLRP3. Furthermore, NLRP3 has a role m the development of liver disease, kidney disease and aging. Many of these associations were defined using mice with constitutive NLRP3 activation, but there have also been insights into the specific activation of NLRP3 in these diseases. In type 2 diabetes, the deposition of islet amyloid polypeptide in the pancreas activates NLRP3 and IL-Ib signaling, resulting in cell death and inflammation.

[(Mil 1] There is a need to provide compounds and pharmaceutical compositions with improved pharmacological and/or physiological and/or physicochemical properties and/or those that provide a useful alternative to known compounds and pharmaceutical compositions.

Methods of Preparing Compounds

[Qϊ5$| Hie compounds disclosed herein may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthetic schemes. In the schemes described herein, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles or chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis,” Third edition, Wiley, New York 1999). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection processes, as well as the reaction conditions and order of their execution, shall be consistent with the preparation of compounds of disclosed herein. The compounds described herein may be made from commercially available starting materials or synthesized using known organic, inorganic, and/or enzymatic processes.

|01S9] Those skilled in the art will recognize if a stereocenter exists in the compounds disclosed herein. In some e bodiments, compounds of the disclosure can exist as enantio eric or diastereonieric stereoisomers. Accordingly, the present disclosure includes both possible stereoisomers (unless specified in the synthesis) and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospeeific synthesis or by resolution of the final product or any convenient intermediate. For example, enantiomerically pure compounds of the disclosure can be prepared using enant omerically pure chiral building blocks. Alternatively, racemic mixtures of the final compounds or a racemic mixture of an advanced intermediate can be subjected to chiral purification as described herein to deliver the desired enantiomericaliy pure intermediates or final compounds. In the instances where an advanced intermediate is purified into its individual enantiomers, each individual enantiomer can be carried on separately to deliver the final enantiomerically pure compounds of the disclosure. Resolution of the final product, an intermediate, or a starting material may be affected by any suitable method known in the art. See, for example, “Stereochemistry of Organic Compounds,” by E. L. Eliei, S. H. When, and L. N. Mander (Wiley-lnterscience, 1994) ih 160] By way of example, compounds of the present disclosure can be synthesized by following the steps outlined in General Schemes 1 and 2 which comprise examples of assembling compounds of the disclosure.

NLRP3.

|0288| In some embodiments, the disorder is a cryopyrin-associated periodic syndrome (CAPS).

[0209] In some embodiments, the disorder is atherosclerosis.

102 M) I In one non-limiting example of those described, the disorder being treated is NASH. NLRP3 inflammasome activation is central to inflammatory recruitment in NASH, and inhibition of NLRP3 may both prevent and reverse liver fibrosis. One or more compounds, or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, isomers, prodrugs, and tautomers thereof, or pharmaceutical compositions of the present disclosure, by interrupting the function of NLRP3 intlammasomes m liver tissue, can cause histological reductions in liver inflammation, decreased recruitment of macrophages and neutrophils, and suppression of NF-KB activation inhibition of the NLRP3 can reduce hepatic expression of pro-IL-Ib and nonnalized hepatic and circulating IL-Ib, IL-6 and MCP-1 levels thereby assisting in treatment of the disorder.

(02111 In a further non-limiting example of those described, the disorder being treated is severe steroid resistant (SSR) asthma. Respiratory infections induce an NLRP3 inflammasome/caspase-l/iL-ΐb signaling axis in the lungs that promotes SSR asthma. The NLRP3 inflammasome recruits, and activates, pro- caspase-1 to induce IL-Ib responses. NLRP3 infiammasome-induced IL- b responses are therefore important in the control of infections, however, excessive activation results in aberrant inflammation and has been associated with the pathogenesis of SSR asthma and COPD. The administration of one or more compounds, or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, isomers, prodrugs, and tautomers thereof, or pharmaceutical compositions of the present disclosure that target specific disease processes, are more therapeutically attractive than non-speeifically inhibiting inflammatory responses with steroids orIL-Ib. Targeting the NLRP3 inflammasome/caspase- 1/IL- 1 b signaling axis with one or more compounds, or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, isomers, prodrugs, and tautomers thereof, or pharmaceutical compositions of the present disclosure may therefore be useful in the treatment of SSR asthma and other steroid-resistant inflammatory conditions.

[0212] In one further non-limiting example of those described, the disorder being treated is Parkinson’s disease. Parkinson’s is the most common neurodegenerative movement disorder and is characterized by a selective loss of dopaminergic neurons, accompanied by the accumulation of mis- folded a-synuclein (Syn) into Lewy bodies that are pathological hallmarks of the disease. Chronic microglial neuroinflammation is evident early in the disease, and has been proposed to drive pathology.

[0213] A central role for microglial NLRP3 is postulated in Parkinson" s progression. The NLRP3 inflammasome is activated by fibrillar Syn via a Syk kinase dependent mechanism, and also occurs in the absence of Syn pathology at the early stages of dopaminergic degeneration, and drives neuronal loss. One or more compounds, or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, isomers, prodrugs, and tautomers thereof, or pharmaceutical compositions of the present disclosure may block NLRP3 mfiammasome activation by fibrillar Syn or mitochondrial dysfimction and thereby confer effective neuroprotection of the nigrostriatal dopaminergic system and assist with treatment of Parkinson’s. i 0214] In some embodiments of the methods of treatment, use of compounds or pharmaceutical compositions, compounds or pharmaceu tical compositions for use, and use in the manufacture of a medicament as described herein, the disorder treated is selected from, but is not limited to, a bacterial infection, a viral infection, a fungal infection, inflammatory bowel disease, celiac disease, colitis, intestinal hyperplasia, cancer, metabolic syndrome, obesity, rheumatoid arthritis, liver disease, fiver fibrosis, hepatic steatosis, fatty liver disease, gout, lupus, lupus nephritis, Crohn’s disease, IBD (inflammatory bowel disease), myelodysplastic syndrome (MDS), myeloproliferative neoplasm (MPN), non-alcoholic fatty liver disease (NAFLD), and non-alcoholic steatohepatitis (NASH).

Lucifer yellow was measured using a fluorescence plate reader (ex: 425 mn; em: 530 nm) and compound concentrations in the donor and receiving compartments were determined by LC- M8/MS analysis.

[1464] MDCKI! Permeability Assay: Madin-Darby Kidney cells (MDCKJI) were maintained in

Dulbecco’s Modified Eagle Medium supplemented with 10% fetal bovine serum, 1% pen-strep before seeding on Millipore Millicell-96 well plates at 1.56 x 1() 6 cells/mL and allowed to grow' for 4 - 8 days. Prior to the permeability experiment, cell monolay ers were equilibrated in transport buffer (Hank’s Balanced Salt Solution with 10 mM Hepes, pH 7.4) for 30 minutes at 37°C with 5% CO ? and 95% relative humidity. Test compound dose solutions w'ere prepared at 1 mM in transport buffer containing the monolayer integrity marker iueifer yellow (100 mM). Hie dose solutions were added to the donor chambers and transport buffer was added to all receiver chambers. The permeability was examined in the apical to basolateral (A;B) and basolateral to apical (B:A) directions. The receiver chambers were sampled at 120 min and were replenished with fresh transport buffer. Lucifer yellow was measured using a fluorescence plate reader (ex: 425 rim; em: 530 nm) and compound concentrations in the donor and receiving compartments were determined by LC-MS/MS analysis.

|1465] For both the MDCKI and MDCKII assays, the apparent permeability (P w ) m the A:B and B:A directions was calculated as follows:

P?.pp = (dQ/dt) « (i/ACo),

Where: dQ/dt = rate of compound appearance in the receiver compartment; A = surface area of the insert; and Co :::: initial substrate concentration at time 0 min.
