Background Technology
[0006] NOD-like receptor 3 (NLRP3) is a protein-coding gene that belongs to the nucleotide-binding and oligomerization domain (NOD)-like receptor (NLR) family. NLRP3 encodes a protein containing a pyrin domain, a nucleotide-binding site domain (NBD), and leucine-rich repeat (LRR) motifs. In response to sterile inflammatory danger signals, NLRP3 interacts with the adaptor protein, apoptosis-associated speck-like protein (ASC), and pro-caspase-1 to form the NLRP3 inflammasome. Subsequent NLRP3 inflammasome activation can induce a number of related diseases by leading to the release of the proinflammatory cytokines IL-1P and IL-18. Activated cytokines derived from NLRP3 inflammasome activation are important drivers of inflammation and interact with other cytokine pathways to format the immune response to infection and injury. For example, IL-1P signaling induces the secretion of the proinflammatory cytokines IL-6 and TNF. IL-1P and IL-18 synergize with IL-23 to induce IL-17 production by x8 T cells and memory CD4 Th17 cells in the absence of T cell receptor engagement. IL-18 and IL-12 also synergize to induce IFN-x production from memory T cells and NK cells, which promote Th1 responses.
[0007] NLRP3 inflammasome activation is associated with various inflammasome-related diseases / disorders, immune diseases, inflammatory diseases, autoimmune diseases and autoinflammatory diseases, for example, autoinflammatory febrile syndromes such as cryopyrin-associated periodic syndrome (CAPS) (Mor timer et al., Nature Immunol. 2016, 17(10), 1176-1188): sickle cell disease; Systemic lupus erythematosus (SLE); Liver-related diseases / disorders, such as chronic liver disease, viral hepatitis, non-alcoholic steatohepatitis (NASH, Hugh Thomas Nature Reviews Gastroenterology & Hepatology 2017:14, 197), alcoholic steatohepatitis and alcoholic liver disease (Petrasek et al., J. Cl in. Invest.2012, 122, 3476—89; Petrasek et al., Nat. Rev. Gastroenterol. Hepatol.2015, 12, 387—400; Mr i dha, AR 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-associated inflammation and diabetic nephropathy, also called diabetic kidney disease (which is a kidney-related complication of diabetes (type 1, type 2 and diabetes mellitus)) (Shahzad et al., Kidney Int. 2015, 87, 74-84). Furthermore, the involvement of increased production of IL-1P and IL-18 by NLRP3 inflammasome has been implicated in various diseases, such as neuroinflammation-related disorders, such as brain infection, acute injury, multiple sclerosis, Alzheimer's disease and neurodegenerative diseases (hao et al. , Front. Pharmacol. 2015, 6, 262); cardiovascular / metabolic disorders / diseases, such as 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); wound healing and scar formation; It has been shown that it may contribute to the development and progression of inflammatory skin diseases such as acne, hidradenitis suppurativa (Sweeney et al., Br. J. Dermatol. 2015, 173, 1361), asthma, sarcoidosis, age-related macular degeneration; and cancer-related diseases / disorders such as myeloproliferative neoplasms, leukemia, myelodysplastic syndrome (MDS), myelofibrosis, lung cancer, and colon cancer (Ridker et al., Lancet 2017, 390, 1833-42). Inherently immune or inflammatory diseases / disorders are generally difficult to diagnose or treat effectively.Most treatments involve treating symptoms, slowing the progression of the disease / disorder, lifestyle changes, and surgery as a last resort (e.g., open heart surgery for advanced forms of atherosclerosis). Recent studies have linked mitochondrial dysfunction and NLRP3 activation in neuroinflammation-related diseases such as Parkinson's disease (Sarkar et al., npj Parkinson's disease 2017, 3:30; Zhou et al., Nature, 2011, 469, 221). One of the major problems associated with mitochondrial modulators is their poor metabolic stability; therefore, selective and stable inhibitors are needed for this type of neuroinflammation (Lee et al., Eur J. Org. Chem. 2017, 141, 240). These inflammasome-related diseases / disorders and others, such as autoinflammatory febrile syndrome cryopyrin-associated periodic syndrome (e.g., CAPS), sickle cell disease, chronic liver disease, nonalcoholic steatohepatitis (NASH), gout, hyperoxaluria, There is a need for inhibitors of the NLRP3 inflammasome pathway to provide new and / or alternative treatments for pseudogout (chondrocalcinosis), type I / type II diabetes and related complications (e.g., nephropathy, retinopathy), neuroinflammation-related disorders (e.g., multiple sclerosis, brain infections, acute injuries, 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, leukemia, myelodysplastic syndromes (MDS), myelofibrosis).

Human cell line THP-1 (ATCC) was cultured in RPMI medium [RPMI (Hyclone) + 10% fetal bovine serum (Hyclone) + 1% penicillin-streptomycin (Hyclone) + 0.05 mM 2-mecaptoethanol].
[0348] J774A.1 cells were seeded at a density of 100,000 cells / well in a 96-well plate (tissue culture plate, 96 well, Falcon), treated with LPS (Sigma) (2 ug / ml) for 4 hours, and then treated with each of the compounds of the present invention (0.001 to 10,000 nM) for 30 minutes. Thereafter, inflammasome was induced by treatment with ATP (Sigma) (5 mM) for 1 hour.

Thereafter, inflammasomes were induced by treatment with nigericin (sigma) (5 uM).
[0350] IL-ip was measured using an ELISA kit (Invitrogen) according to the manufacturer's instructions, and absorbance was measured at 450 nm using a spectrophotometric microplate reader (BioTek, Synergy H4). IC50 values were calculated based on inflammasome-induced and non-induced samples. The results are shown in Table 11 below.
[0351] [Table 11] As can be confirmed in Table 11 above, the compound of the present invention exhibits inflammasome inhibitory activity. Experimental Example 2: Evaluation of CYP (Cytrochrome P450) activity inhibition ability 7} In order to evaluate the activity inhibition ability of the compound of the present invention against CYP (Cytochrome P450), the inhibitory activity of the compound of the present invention against drug metabolizing enzymes, CYP3A4 and CYP2C9, which are known to be important in drug metabolism in humans, was evaluated. Specifically, the inhibitory activity analysis of CYP3A4 and CYP2C9 was performed using Invitrogen (P2861, P2858) kits. In the case of the above Invitrogen kit, the compound of the present invention was prepared by diluting it in Vivid CYP450 reaction buffer (lx) to 2.5X the final experimental concentration, and the P450 BACULOSOMES sample and the Regenerat ion system (100x) were prepared by diluting it in Vivid CYP450 reaction buffer (lx) to a concentration appropriate for the CYP450 type. In a U-bottom 96-well plate, 40 M of the compound of the present invention prepared at 2.5X the final experimental concentration and 50 seeds of the diluted P450 BACULOSOMES sample mixture were mixed, and pre-incubation was performed for 20 to 30 minutes. After diluting Vivid CYP450 Substrate and NADP+ (100>〈 ) in Vivid CYP450 reaction buffer (IX) at a concentration appropriate for the CYP450 and substrate types, 10 M of Substrate-NADP+ mix was added to the plate where the pre-reaction was completed and reacted for 30 minutes to 1 hour.After the reaction was completed, the reactants were transferred to a white plate and the fluorescence wavelengths were read in a microplate reader (1A2, 2B6, 2C9, 2C19, 2D6, 3A4 excitation 409 nm, emission 460 nm, 2C8 excitation 485 nm, emission 535 nm). The experimental results were calculated as (1-(test substance fluorescence value / vehicle fluorescence value)) X 100% and are shown in Table 12 below.
[0352] [Table 12] In general, if a compound at a concentration of 10 iiM inhibits the activity of a CYP enzyme by more than 50%, it is predicted to be a substance requiring attention regarding the activity of the CYP enzyme.

Experimental Example 3: Evaluation of In vivo Interleukin-13 (IL-13) Inhibitory Ability In order to evaluate the inflammasome activity inhibitory ability of the compound of the present invention, the following was performed. After orally administering the compound of the present invention to 6-8 week old C57BL / 6J male mice, one hour later, LPS (Lipopoly saccharide, Invivogen) dissolved in saline was intraperitoneally injected at 50 drops per mouse. Two hours after LPS injection, inflammasomes were induced by intraperitoneal injection of 12.5 mg of ATP (adenosine triphosphate, Sigma) dissolved in saline per mouse. Thirty minutes after ATP injection, blood was collected through a capillary tube from the orbital vein of the mice. The blood was collected in 1.7 ml tubes and centrifuged at 6000 g, 4 °C, and 5 min to separate the plasma. To measure IL-1P in the plasma, the absorbance was measured at 450 nm using an ELISA kit (Invitrogen) and a spectrophotometric microplate reader according to the manufacturer's instructions. The concentration of IL-1P in the plasma was calculated from the absorbance, and the inflammasome inhibition efficacy was indicated as the ratio of the decrease in IL-1P compared to the vehicle (0.5% methylcellulose). The results are shown in Table 13 below.

Experimental Example 4: Evaluation of hERG channel binding inhibition ability In order to evaluate the binding inhibition ability of the compound of the present invention to the hERG channel, the binding inhibition ability was evaluated using the Predictor hERG fluorescence polarization assay kit (Invitrogen). In the case of the Invitrogen kit, the hERG tracer and membrane fraction were prepared by melting at room temperature before use. The tracer and hERG assay buffer were diluted 1:62.5. The negative control group was used with the hERG assay buffer. The positive control E-4031 was prepared by diluting 1:25 with the hERG assay buffer. The compound of the present invention was prepared by diluting it in the hERG assay buffer (lx) to 4x the final experimental concentration. Each diluted compound solution was dispensed into 384-well low-volume flat-bottom microplates at 10 μl. Twenty-five microliters of each membrane fraction was dispensed into each well. Ten microliters of each hERG tracer was dispensed. The plates were incubated at 25°C for 2 hours in a light-blocking manner. Fluorescence polarization (MP) was measured using a microplate reader (Bioteck Synergy H4) at Excitation 530 nm and Emission 590 nm. The experimental results were calculated as (compound MP - negative control MP) / (positive control MP - negative control MP) X 100% and are shown in Table 14 below.

As can be confirmed in Table 14 above, the inhibition rate of the compound of the present invention at a concentration of 10 iiM is less than 50%, indicating that hERG K + It is judged to be safe for inducing cardiotoxicity by CHANNEL binding. Experimental Example 5: To determine the NASH inhibitory efficacy of the NASH efficacy evaluation compound, the following is performed. 5-week-old male C57BL / 6J mice were housed under standard conditions (24 °C, 50% humidity, 12:12 light / dark cycle) and had a one-week acclimation period with normal food and water. In order to induce NASH in the mice, the mice were fed an MCD (Methionine-Chol ine Deficient) diet for 4 weeks, and thereafter, the vehicle, positive control drug, and the compound of the present invention were administered orally for 4 weeks simultaneously with the MCD diet. On the last day of the study, the mice were anesthetized with an isoprene solution, and blood was collected through the abdominal vena cava, and the mice were sacrificed by C02 asphyxiation to collect the liver. The collected blood was placed in a 1.7 ml tube and centrifuged at 6000 g, 4 ° C, for 5 minutes to separate the plasma. Liver values such as ALT and AST and the concentration of neutral fat in the blood were tested using a plasma and blood biochemistry analyzer. The liver was immediately treated with a formalin solution and stained later to determine the degree of fibrosis.
