Background Art
[0004] Inflammation is a protective immune response produced by the innate immune system in response to harmful stimuli such as pathogens, dead cells or irritants, and is strictly regulated by the host. Insufficient inflammation can lead to persistent infection with pathogens, while excessive inflammation can cause chronic or systemic inflammatory diseases. Inflammasomes are protein complexes that play a role in initiating and controlling inflammatory responses. Excessive triggering of inflammasomes leads to unnecessary inflammation and inflammatory diseases. Therefore, inflammasomes are associated with a variety of autoinflammatory and autoimmune diseases, including neurodegenerative diseases such as inflammatory bowel disease, Crohn's disease, multiple sclerosis, Alzheimer's disease and Parkinson's disease. It is interesting to control inflammation by regulating the activity of inflammasomes and their components. Summary of the Invention

DETAILED DESCRIPTION
[0047] The human body mounts an inflammatory response when exposed to pathogens, tissue damage, and endogenous stressors. The inflammatory response is triggered by pattern recognition receptors (PRRs). Signaling downstream of PRRs leads to the expression of proinflammatory cytokines such as TNFα, IL-1β, IL-6, IL-18, and others. Inflammation can be used to fight pathogens, but excessive inflammation can lead to chronic or systemic inflammatory diseases, in which the body's immune system begins to attack its own healthy cells. However, lower levels of inflammation lead to ineffective pathogen destruction, resulting in persistent infection. Therefore, the level of inflammation needs to be tightly regulated.
[0048] The inflammatory response is initiated and controlled by protein complexes called inflammasomes, which are found in macrophages and neutrophils. When inflammasomes are overactive, diseases such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), Crohn's disease, Alzheimer's disease, arthritis, and multiple sclerosis can result. These diseases occur when the proinflammatory cytokines mentioned above trigger unwanted cell death. While this cell death is an integral part of the immune response to fight infection, excessive inflammasome activity triggers unwanted cell death, thereby triggering a variety of autoimmune diseases, such as those mentioned above.
[0049] Without being bound by theory, it is believed that a specific family of proteins called apoptosis-associated speck-like proteins (containing a C-terminal caspase recruitment domain, abbreviated as ASC) interact with procaspase-1 to at least partially trigger the inflammasome response that leads to cell death. (See Figure 1 ). ASC regulates the assembly and activation of multiple inflammasomes. The adaptor molecule ASC plays a role in the stimulation and assembly of linked inflammasomes by providing multiple interaction surfaces through its N-terminal PYRIN-PAAD-DAPIN domain (PYD) and C-terminal caspase recruitment domain (CARD). Both the PYD and CARD domains belong to the death domain superfamily and have a characteristic six-helix bundle fold. ASC brings monomers of pro-caspase-1 into proximity, which triggers caspase-1 autocleavage and the formation of active heterotetrameric caspase-1. Active caspase-1 proteolytically activates several proteins, including cytokines such as pro-IL-1β and pro-IL-18 (see Figure 1 ), inducing their release via the nonclassical secretory pathway.
[0050] Some embodiments of the present invention provide first-in-class pan-inflammasome inhibitors targeting ASC with broad anti-inflammatory effects. The compounds disclosed herein inhibit ASC protein oligomerization, which in turn disrupts inflammasome assembly, thereby limiting inflammation by targeting multiple inflammasome pathways. Therefore, certain embodiments of the present invention have the potential to limit inflammation in various gastrointestinal and other inflammatory conditions (see Figure 2 ).

[0172] Pharmaceutical composition
[0173] In certain embodiments, the compounds described herein are administered as pure chemicals. In other embodiments, the compounds described herein are combined with a pharmaceutically suitable or acceptable carrier (also referred to herein as a pharmaceutically suitable (or acceptable) excipient, a physiologically suitable (or acceptable) excipient, or a physiologically suitable (or acceptable) carrier) selected based on the selected route of administration. Typical administration is by injection or oral administration. Suitable forms of administration include, but are not limited to, oral, rectal, topical, intraperitoneal, buccal, parenteral (e.g., subcutaneous, intramuscular, intradermal, or intravenous), rectal, vaginal, or aerosol administration.
[0174] Thus, provided herein is a pharmaceutical composition comprising at least one compound described herein, a pharmaceutically acceptable salt, hydrate, solvate or N-oxide thereof and one or more pharmaceutically acceptable carriers. A carrier (or excipient) is acceptable or suitable if it is compatible with the other ingredients of the composition and is not harmful to the recipient (i.e., subject) of the composition.
[0175] One embodiment provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a compound of formula (I) or a pharmaceutically acceptable salt or solvate thereof.
[0176] Another embodiment provides a pharmaceutical composition consisting essentially of a pharmaceutically acceptable carrier and a compound of formula (I) or a pharmaceutically acceptable salt thereof.
[0177] In certain embodiments, the compounds described herein are substantially pure in that they contain less than about 5%, or less than about 1%, or less than about 0.1% of other small organic molecules, such as contaminating intermediates or by-products produced, for example, during one or more steps of the synthetic methods.
[0178] In some cases, exemplary pharmaceutical compositions are used in the form of pharmaceutical preparations, for example, in solid, semisolid or liquid form, which include one or more disclosed compounds as active ingredients, mixed with organic or inorganic carriers or excipients suitable for external, enteral or parenteral application. In some embodiments, the active ingredients are mixed with conventional non-toxic, pharmaceutically acceptable carriers, for example, for tablets, pills, capsules, suppositories, solutions, emulsions, suspensions and any other form suitable for use. The active target compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect on the disease process or condition.
[0179] To prepare solid compositions such as tablets, in some cases, the main active ingredient is mixed with a pharmaceutical carrier (e.g., conventional tableting ingredients) to form a solid preformulation composition containing a homogeneous mixture of the disclosed compound or a non-toxic pharmaceutically acceptable salt thereof. When these preformulation compositions are referred to as homogeneous, it is meant that the active ingredient is evenly dispersed throughout the composition so that the composition can be easily subdivided into equally effective unit dosage forms, such as tablets, pills, and capsules.
[0180] In solid dosage forms (capsules, tablets, pills, dragees, powders, granules, etc.) for oral administration, the subject composition is mixed with one or more known pharmaceutically acceptable carriers. In the case of capsules, tablets and pills, in some embodiments, the composition also comprises a buffer. Similar types of solid compositions are also used as fillers in soft-filled and hard-filled gelatin capsules using excipients such as lactose or milk sugar, and high molecular weight polyethylene glycols, etc.
[0181] In some cases, tablet is made by compression or molding, optionally with one or more auxiliary ingredients. Use binding agent, lubricant, inert diluent, preservative, disintegrant and / or surfactant or dispersant to prepare compressed tablet. Prepare molded tablet by molding the mixture of the subject composition moistened with inert liquid diluent in a suitable machine. Tablet and other solid dosage forms, such as dragee, capsule, pill and granule, optionally with coating and shell (such as other coatings known to enteric coating and pharmaceutical formulation field) score or preparation.
[0182] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable aqueous or organic solvents, or mixtures thereof, and powders. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the subject composition, the liquid dosage form may contain an optional inert diluent commonly used in the art.
[0183] In addition to the subject composition, the suspension optionally contains known suspending agents and mixtures thereof.
[0184] In some embodiments, formulations for rectal or vaginal administration are presented as suppositories, which are prepared by mixing the subject compositions with one or more suitable non-irritating excipients or carriers that are solid at room temperature but liquid at body temperature and therefore will melt in the body cavity and release the active agent.
[0185] Dosage forms for transdermal administration of the subject compositions include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches, and inhalants. The active ingredient is optionally mixed under sterile conditions with a pharmaceutically acceptable carrier and, in some embodiments, any preservatives, buffers, or propellants desired.
[0186] In some embodiments, ointments, pastes, creams, and gels contain, in addition to the subject compositions, excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc, and zinc oxide, or mixtures thereof.
[0187] In some embodiments, powders and sprays contain, in addition to the subject composition, known excipient mixtures of these substances. Sprays also contain conventional propellants such as chlorofluorocarbons and volatile unsubstituted hydrocarbons such as butane and propane.
[0188] Alternatively, compositions and compounds disclosed herein are administered by aerosol. This is achieved by preparing aqueous aerosols, liposome preparations or solid particles containing the compound. Non-aqueous (e.g., fluorocarbon propellants) suspensions can be used. Sonic wave sprayers are used because they minimize the exposure of reagents to shear, and in some embodiments, shearing causes the degradation of the compound contained in the subject composition. Typically, aqueous aerosols are prepared by preparing an aqueous solution or suspension of the subject composition together with a conventional pharmaceutically acceptable carrier and stabilizer. Carrier and stabilizer vary with the requirements of the specific subject composition, but typically include nonionic surfactants. Aerosols are typically prepared by isotonic solutions.
[0189] Pharmaceutical compositions suitable for parenteral administration comprise a combination of the subject compositions with one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders for reconstitution into sterile injectable solutions or dispersions immediately before use, optionally containing antioxidants, buffers, bacteriostats, solutes that render the formulation isotonic with the blood of the intended recipient, or suspending or thickening agents.
[0190] Also contemplated are enteral pharmaceutical formulations comprising the disclosed compounds and enteric materials and pharmaceutically acceptable carriers or excipients thereof. An enteric material is a polymer that is substantially insoluble in the acidic environment of the stomach and primarily soluble in intestinal fluid at a specific pH. The small intestine is the portion of the gastrointestinal tract (intestines) between the stomach and the large intestine and includes the duodenum, jejunum, and ileum. The pH of the duodenum is about 5.5, the pH of the jejunum is about 6.5, and the pH of the distal ileum is about 7.5. Thus, the enteric material is insoluble, for example, until the pH is about 5.0, about 5.2, about 5.4, about 5.6, about 5.8, about 6.0, about 6.2, about 6.4, about 6.6, about 6.8, about 7.0, about 7.2, about 7.4, about 7.6, about 7.8, about 8.0, about 8.2, about 8.4, about 8.6, about 8.8, about 9.0, about 9.2, about 9.4, about 9.6, about 9.8, or about 10.0.
[0191] In some embodiments, the dosage of a composition comprising at least one compound as described herein varies depending on the condition of the patient (e.g., human), i.e., the stage of the disease, general health, age, and other factors that one skilled in the medical art would use to determine dosage.
[0192] In some cases, pharmaceutical composition is used in a manner suitable for the disease to be treated (or prevention) determined by medical field technicians. Suitable dosage and suitable duration of application and frequency will be determined by factors such as the patient's condition, the type and severity of the patient's disease, the specific form of active ingredient and the method of administration. Usually, suitable dosage and treatment regimen provide compositions (for example, improved clinical results, such as more frequent complete or partial relief, or longer disease-free and / or total survival, or the alleviating of symptom severity) in an amount that is enough to provide treatment and / or prevention benefit. Optimal dose is usually determined using experimental models and / or clinical trials. In some embodiments, optimal dose depends on patient's body weight, weight or blood volume.

[0303] The synthesis of new compounds with modified core structures can be achieved using two different strategies. First, compounds 5 / 6 are chemically modified by substitution / reaction with suitable reagents to introduce the desired modifications into the core structure. These modifications include functional group modifications and ring substitutions. Secondly, commercially available key starting materials that already have the substitutions or functional groups necessary to synthesize the core structure are used for synthesis. The selection of reagents, reaction conditions, and protecting groups plays a crucial role in the successful implementation of these strategies. Side chains can be incorporated into the modified core structure using the same synthetic scheme disclosed for compound 6.
[0304] Example 2 - Inhibition of IL-1β production in vitro
[0305] The following examples demonstrate the efficacy of compounds of the present disclosure in inhibiting the production of cytokines such as interleukin-1β in a dose-dependent manner in vitro. The procedures detailed herein can be used to test all compounds of the present disclosure.
[0306] Human mononuclear THP-1 cells were treated with phorbol 12-myristate 13 acetate (PMA) (100 nM) overnight to differentiate monocytes into macrophages. Then, after standing for 24 hours, the differentiated cells were incubated with test compounds at concentrations of 0.01, 0.1, 1, 10, 30 and 50 mM for 12 hours. The cells were then washed once with PBS and triggered with E. coli LPS (0.1 μg / ml) for 4 hours, followed by stimulation with ATP (5 μM) for another 30 minutes. The cell culture supernatant was then collected and the OD value of IL-1β levels was measured by ELISA. A standard curve (OD to concentration) of IL-1β was also drawn and used to determine the IL-1β concentration of the OD value. The percentage inhibition of IL-1β was calculated using the following formula:
[0307]
[0308] The percentage inhibition of IL-1β at different compound concentrations was plotted in a sigmoidal curve, and IC50 values were interpolated in Graphpad Prism. Cell death was assessed by propidium iodide staining and OD was measured at 490 nm. Cell viability was estimated relative to DMSO control. Figure 3 The IC50 value of a representative compound, Compound 6, is shown, which had 99% cell viability at 10 μM, indicating that it was non-toxic to cells within the concentration range tested.
[0309] Example 3 - Inhibition of IL-1β production in vivo
[0310] The following examples demonstrate the efficacy of compounds of the present disclosure in inhibiting the production of cytokines such as interleukin-1β in a dose-dependent manner under in vivo conditions. The procedures detailed herein can be used to test all compounds of the present disclosure. The examples were tested in vivo using an LPS+ATP-induced inflammasome activation model in 8-10 week old male Balb / c mice.
[0311] 8-10 week old male Balb / c mice were challenged with 200 μg / kg (0.2 μg / g) LPS by intraperitoneal (ip) injection at t=0 hours, followed by an intraperitoneal injection of 5 mM ATP solution at t=2 hours (2 hours after LPS challenge). Compounds of the present disclosure being tested for inhibitory activity (e.g., Compound 6) were administered intraperitoneally and orally at -1 hour. As shown below, different doses of compounds of the present disclosure were administered to mice after LPS induction.
[0312] MCC950, a specific small molecule inhibitor of NLRP3 inflammasome, was used as a positive control to be able to compare the inhibitory activity of the compounds disclosed herein with known inhibitors. 2.5 hours after LPS induction (or 0.5 hours after ATP administration), blood was collected in heparinized blood collection tubes by retroorbital bleeding. The blood was centrifuged at 10,000 rpm for 5 minutes in a refrigerated centrifuge to obtain plasma. The separated plasma was used to evaluate cytokines by ELISA. A standard curve of IL-1β (OD versus concentration) was also drawn and used to determine the IL-1β concentration of the OD value. The percentage inhibition of IL-1β was calculated using the following formula:
[0313]
[0314] The following groups were evaluated and observed for IL-1β suppression:
[0315] Group dose Route of administration N % IL-1β inhibition Sham operation control - - 6 - LPS control - - 6 - LPS+ATP - - 6 - MCC950 20 mg / kg intraperitoneally 6 95% Compound 6 1 mg / kg intraperitoneally 6 52% Compound 6 10 mg / kg intraperitoneally 6 79% Compound 6 10 mg / kg oral 6 46%
[0316] Figure 4 Compound 6 demonstrated a dose-dependent reduction in IL-β in an in vivo mouse model. Notably, the compound exhibited 79% inhibition of IL-1β at 10 mg / kg intraperitoneal dose and 46% inhibition of IL-1β at 10 mg / kg oral dose. MCC950 was used as a tool compound in this assay.
[0317] Therefore, the compounds of the present disclosure showed significant inhibition of IL-1β production in the LPS+ATP-induced inflammasome activation mouse model.

At the end of 90 minutes, the sample was filtered using the MultiScreen HTS vacuum manifold assembly, and the filtrate was collected in a receiving plate. 150 μL filtrate aliquots from the above-mentioned 96-well receptor plate were transferred to HPLC vials and analyzed by HPLC-PDA. Solubility was determined by comparing the absorbance of the test / reference compound with the corresponding DMSO calibration curve. The solubility of compound 6 in phosphate buffered saline (pH 7.4) was tested by kinetic method. The compound was highly soluble with a solubility of >200 μM.
[0322] Metabolic stability assays in mouse, rat, and human liver microsomes
[0323] The test was performed in duplicate with a final test concentration of 1 μM. The incubation was carried out for 45 minutes with intermediate time points of 0, 5, 15 and 30 minutes. Verapamil was used as the reference standard for the experiment. The concentration of verapamil was 1 μM. For the microsomal stability experiment, the vial containing the microsomes was thawed in an ice bath. 33 μL of microsomes (20 mg / mL) was suspended in 1165.7 μL of 100 mM potassium phosphate buffer (pH 7.4) in a propylene tube labeled as incubation mixture. The control and test compounds will have a similar set of incubation mixture tubes. 1.1 μL of compound 6 or verapamil (1 mM) was added to the above incubation mixture to obtain a working concentration of 1.1 μM. 180 μL aliquots from the incubation mixture were transferred to a propylene tube labeled T 对照 、T0、T5、T 15 、T 30 and T 45 of 6 test tubes.
[0324] All tubes were pre-incubated at 37±1°C in a shaking water bath for 5 minutes. NADPH solution (10 mM) tubes were similarly pre-incubated under similar conditions. After pre-incubation, the tubes were heated to T0, T5, T 15 、T 30 and T 45 Add 20 μL of NADPH solution (10 mM) to the tube and 对照20 μ L buffer was added to the tube to make the final concentration reach 1 μ M respectively. Immediately, T0 was quenched with 200 μ L quenching solution containing warfarin as internal standard (IS). Similarly, at the end of the incubation period (5, 15, 30 and 45 minutes) of each test tube, 200 μ L quenching solution containing warfarin as internal standard (IS) was added to each test tube to terminate the reaction. The obtained sample was centrifuged at 3220 g (relative centrifugal force) for 20 minutes. The supernatant (200 μ L) from each reaction tube was taken for LC-MS / MS analysis.
[0325] The calculation is as follows:
[0326] Remaining % = 100 x (PAR at designated incubation time / PAR at T0)
[0327] Elimination rate constant (k) = (- gradient)
[0328] Half-life (t1 / 2) = 0.693 / k
[0329] V (μL / mg) = incubation volume (μL) / protein in incubation (mg)
[0330] Microsomal intrinsic clearance (mCLint) (μL / min / mg protein) = (V*0.693) / t1 / 2
[0331] Where PAR is the peak area ratio of the analyte to the internal standard (IS)
[0332] The stability of compound 6 in mouse, rat and human liver microsomes when incubated with reference standard verapamil is shown in the following table:
[0333]
[0334] The reference standard verapamil showed extensive metabolism by liver microsomes, well within the mCLint acceptance criteria (human: <8.60 low and >47.0 high, rat: 13.2 low and >71.9 high, mouse: <8.80 low and >48.0 high).

[0362] Example 7 - Treatment of Primary Sclerosing Cholangitis
[0363] Primary sclerosing cholangitis (PSC) is a chronic liver disease in which bile ducts within and outside the liver become inflamed, scarred, and eventually narrowed or blocked. In PSC, inflammation leads to scarring within the bile ducts. This scarring hardens and narrows the ducts, gradually causing severe liver damage. Most people with PSC also have inflammatory bowel disease, such as ulcerative colitis or Crohn's disease.
[0364] Mdr2 knockout mice are used as an animal model for primary sclerosing cholangitis. Male FVB / NJ WT and Mdr2 knockout mice aged 9-11 weeks were randomly divided into different groups as shown. Starting from 10 to 12 weeks of age, compounds of the present disclosure, such as Compound 6, were administered intraperitoneally or orally daily. At 12 weeks of age, mice were sacrificed and analyzed for liver and serum bile acid accumulation, liver fibrosis, pro-inflammatory and pro-fibrotic markers.
