Description

CARBAMATE AND UREA DERIVATIVES
BACKGROUND OF THE DISCLOSURE Cross-reference to related applications
[1] This application claims priority from U.S. Application No. 63/015024, filed April 24, 2020, and 63/166083, filed March 25, 2021, the disclosure of each of which is hereby incorporated by reference in its entirety.
Field of the Disclosure
[2] This disclosure relates generally to carbamate- and urea-derived molecules, pharmaceutical compositions comprising them, and methods of using them.
Technical Background
[3] The inflammasome is a large multiprotein complex that plays an important role in both sterile tissue injury and infection. However, due to the potently inflammatory nature of inflammasome- derived mediators, complex regulatory mechanisms have evolved to suppress inflammasome activation in the absence of injury or infection. The importance of such mechanisms is highlighted by activating mutations in the inflammasome pathway that lead to an array of autoinflammatory diseases which can be life threatening. Chronic and acute aberrant activation of the inflammasome pathway also contributes to the pathology of a wide range of arthritic, neurodegenerative, cardiovascular, dermatological, pulmonary and systemic inflammatory conditions.
[4] Assembly of the inflammasome complex is under the control of a ‘two-hit’ system whereby two independent signals are required for activation. Signal 1 stimulates transcription of inflammasome-related genes, leading to upregulation of the individual components of the inflammasome, as well as the production of the pro-form of the inflammasome substrates interleukin-1 b (IL-1 b), interleukin-18 (IL-18) and Gasdermin-D within the cytosol. Signal 2 is provided by an array of pathogen associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs) that are sensed by a family of cytosolic pattern recognition receptors termed nucleotide-binding oligomerization domain-like receptors (NLRs), as well as a few additional inflammasome forming sensors. Binding of the DAMP to its corresponding NLR leads to conformational changes in the NLR allowing self-oligomerization of the receptor. These NLR oligomers then recruits the adapter protein, apoptosis-associated speck-like protein containing a CARD (ASC), nucleating formation of a filament of repeating ASC subunits, mediated through the pyrin domain of ASC. The ASC filaments in turn creates a platform for recruitment of caspase-1 leading autocatalytic cleavage and activation, as well nucleating subsequent caspase-1 filament formation mediated through the caspase-1 CARD domain, which is thought to amplify caspase-1 activation. Active caspase-1 then cleaves pro-IL- 1b, pro-IL-18 and Gasdermin D into their active forms, releasing the inflammatory mediators from the cell and inducing Gasdermin-D mediated pyroptotic cell death.
[5] Inflammasome formation can be initiated by at least 11 different sensors including Pyrin, numerous NLRs including NLRP1 , NLRP3, NLRP6, NLRP7, NLRP12, NLRC4 and NLRC5, the PYHIN family members IFI-16 and AIM2, as well as RIG-I. Conventional approaches to inflammasome inhibition have targeted individual receptors, such as NLRP3, to inhibit a subset of inflammasomes. However, emerging evidence clearly demonstrates that activation of multiple different inflammasome forming receptors is a common pathological feature of many diseases including inflammatory bowel disease, arthritic diseases and neurodegenerative disorders among others. Hence, broader pharmaceutical approaches capable of simultaneously inhibiting multiple species of inflammasomes are needed to address pathological inflammasome-dependent inflammation.
[6] One way to achieve broader inflammasome inhibition is to target the shared components of the inflammasome, such as ASC filaments. Assembly of the inflammasome is induced by a cytosolic sensor (e.g. NLRP3 or AIM2) which detect danger signals associated with infection or sterile injury. Upon sensing these signals, the sensor nucleates formation of long filaments composed of repeating units of the inflammasome adapter protein ASC. These filaments form a scaffold for the recruitment of Caspase-1 leading to autoproteolytic activation of the enzyme. While the inflammasome plays a protective role against infection and injury, aberrant activation of the complex in the absence of infection or injury contributes to a wide range of autoinflammatory conditions. Accordingly, the development of compositions and methods that disrupt assembly of the ASC filament in order to prevent inflammasome driven inflammation is an important challenge.

[57] In the pharmaceutical compositions disclosed herein, one or more compounds of the disclosure may be present in association with one or more pharmaceutically acceptable carriers, diluents or excipients, and, if desired, other active ingredients. The pharmaceutical compositions containing compounds of the disclosure may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsion, hard or soft capsules, or syrups or elixirs.
[58] Compositions intended for oral use can be prepared according to any suitable method for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preservative agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients that are suitable for the manufacture of tablets. These excipients can be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets can be uncoated or they can be coated by known techniques. In some cases such coatings can be prepared by suitable techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate can be employed.
[59] Formulations for oral use can also be presented as hard gelatin capsules, wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin or olive oil.
[60] Formulations for oral use can also be presented as lozenges.
[61] Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients can be suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydropropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents such as a naturally-occurring phosphatide, for example, lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.
[62] Oily suspensions can be formulated by suspending the active ingredients in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents and flavoring agents may be added to provide palatable oral preparations. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.
[63] Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, can also be present.
[64] Pharmaceutical compositions can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents can be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally- occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions can also contain sweetening and flavoring agents.
[65] In some embodiments, the pharmaceutically acceptable carrier, diluent, or excipient is not water. In other embodiments, the water comprises less than 50% of the composition. In some embodiments, compositions comprising less than 50% water have at least 1%, 2%, 3%, 4% or 5% water. In other embodiments, the water content is present in the composition in a trace amount. [66] In some embodiments, the pharmaceutically acceptable carrier, diluent, or excipient is not alcohol. In other embodiments, the alcohol comprises less than 50% of the composition. In some embodiments, compositions comprising less than 50% alcohol have at least 1%, 2%, 3%, 4% or 5% alcohol. In other embodiments, the alcohol content is present in the composition in a trace amount.
[67] Syrups and elixirs can be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations can also contain a demulcent, a preservative, flavoring, and coloring agents. The pharmaceutical compositions can be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension can be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils can be employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
[68] Compounds of the disclosure can also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the compound with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.
[69] Compounds of the disclosure can also be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle. Advantageously, adjuvants such as local anesthetics, preservatives and buffering agents can be dissolved in the vehicle.
[70] The compositions can be formulated in a unit dosage form of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. [71] The compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.
[72] For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound described herein. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of a compound described herein.
[73] The tablets or pills can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.
[74] The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.
[75] The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11 , more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.
[76] The therapeutic dosage of the compounds can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound described herein in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds described herein can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 pg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
[77] The compounds described herein can also be formulated in combination with or administered sequentially with one or more additional active ingredients which can include any pharmaceutical agent such as anti-viral agents, vaccines, antibodies, immune enhancers, immune suppressants, anti-inflammatory agents and the like.
[78] The person of ordinary skill in the art will formulate a compound as described into pharmaceutical formulations herein. For example, based on the physicochemical properties of the compound, one of ordinary skill in the art will recognize a pharmaceutically effective amount of the compound, and the desired route of administration.
Definitions
[79] Terms used herein may be preceded and/or followed by a single dash, or a double dash, “=”, to indicate the bond order of the bond between the named substituent and its parent moiety; a single dash indicates a single bond and a double dash indicates a double bond or a pair of single bonds in the case of a spiro-substituent. In the absence of a single or double dash it is understood that a single bond is formed between the substituent and its parent moiety; further, substituents are intended to be read “left to right” with reference to the chemical structure referred to unless a dash indicates otherwise. For example, arylalkyl, arylalkyl-, and -alkylaryl indicate the same functionality.
[80] For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety can refer to a monovalent radical (e.g., CH3-CH2-), in some circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g., -CH2-CH2-), which is equivalent to the term “alkylene.” Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene. All atoms are understood to have their normal number of valences for bond formation (i.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S). Nitrogens in the presently disclosed compounds can be hypervalent, e.g., an N-oxide or tetrasubstituted ammonium salt. On occasion a moiety may be defined, for example, as -B-(A)a, wherein a is 0 or 1. In such instances, when a is 0 the moiety is -B and when a is 1 the moiety is -B-A.
[81] As used herein, the term “alkyl” includes a saturated hydrocarbon having a designed number of carbon atoms, such as 1 to 10 carbons (i.e., inclusive of 1 and 10), 1 to 8 carbons, 1 to 6 carbons, 1 to 3 carbons, or 1, 2, 3, 4, 5 or 6. Alkyl group may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkylene group). For example, the moiety “-(C1-C6 alkyl)-0-” signifies connection of an oxygen through an alkylene bridge having from 1 to 6 carbons and C1-C3 alkyl represents methyl, ethyl, and propyl moieties. Examples of “alkyl” include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, iso-, sec- and tert-butyl, pentyl, and hexyl.
[82] The term “alkoxy” represents an alkyl group of indicated number of carbon atoms attached to the parent molecular moiety through an oxygen bridge. Examples of “alkoxy” include, but are not limited to, methoxy, ethoxy, propoxy, and isopropoxy.

Alkenyl group may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkenylene group). For example, the moiety “-(C2-C6alkenyl)-0-” signifies connection of an oxygen through an alkenylene bridge having from 2 to 6 carbons. Representative examples of alkenyl include, but are not limited to, ethenyl, 2-propenyl, 2- methyl-2-propenyl, 3-butenyl, 4-pentenyl, 5-hexenyl, 2-heptenyl, 2-methyl-1-heptenyl, 3- decenyl, and 3,7-dimethylocta-2,6-dienyl.

Alkynyl group may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkynylene group). For example, the moiety “-(C2-C6alkynyl)-0-” signifies connection of an oxygen through an alkynylene bridge having from 2 to 6 carbons. Representative examples of alkynyl include, but are not limited to, acetylenyl, 1-propynyl, 2- propynyl, 3-butynyl, 2-pentynyl, and 1-butynyl.
[85] The term “aryl” represents an aromatic ring system having a single ring (e.g., phenyl) which is optionally fused to other aromatic hydrocarbon rings or non-aromatic cycloalkyl or heterocycloalkyl rings.

The term “fluorinated” indicates a group (such as alkyl as otherwise described herein) wherein at least one of the carbon-bound hydrogens is substituted by fluorine to form C-F groups. Examples of fluorinated alkyl groups are fluoromethyl, difluoromethyl and trifluoromethyl. Trifluoromethyl is a perfluorinated alkyl group.

[95] One of ordinary skill in the art of medicinal chemistry also will appreciate that the disclosed structures are intended to include isotopically enriched forms of the present compounds. As used herein “isotopes” includes those atoms having the same atomic number but different mass numbers. As is known to those of skill in the art, certain atoms, such as hydrogen occur in different isotopic forms. For example, hydrogen includes three isotopic forms, protium, deuterium and tritium. As will be apparent to those of skill in the art upon consideration of the present compounds, certain compounds can be enriched at a given position with a particular isotope of the atom at that position. For example, compounds having a fluorine atom, may be synthesized in a form enriched in the radioactive fluorine isotope 18F. Similarly, compounds may be enriched in the heavy isotopes of hydrogen: deuterium and tritium; and similarly can be enriched in a radioactive isotope of carbon, such as 13C. Such isotopic variant compounds undergo different metabolic pathways and can be useful, for example, in studying the ubiquitination pathway and its role in disease. Of course, in certain embodiments, the compound has substantially the same isotopic character as naturally-occurring materials.
[96] One of ordinary skill in the art of chemistry will also appreciate that the disclosed structures, unless otherwise indicated are intended to include all possible stereoisomers of the claimed molecule, including mixtures of certain or all stereoisomers. However, compounds drawn with certain stereochemistry at one or more stereocenters are intended to have the indicated stereochemistry. Compounds and stereocenters drawn with ambiguous stereochemistry are meant to convey any stereoisomer or mixture thereof, e.g., a racemic mixture of compounds or a purified subset of stereoisomers.
[97] As used herein, the terms “individual,” “patient,” or “subject” are used interchangeably, refers to any animal, including mammals, preferably humans.
[98] As used herein, the phrase “therapeutically effective amount” or “effective amount” refers to the amount of active compound or pharmaceutical agent that elicits the biological or medicinal response that is being sought in a tissue, system, animal, individual or human by a researcher, veterinarian, medical doctor or other clinician.
[99] In certain embodiments, an effective amount can be an amount suitable for
(i) inhibiting the progression the disease;
(ii) prophylactic use for example, preventing or limiting development of a disease, condition or disorder in an individual who may be predisposed or otherwise at risk to the disease, condition or disorder but does not yet experience or display the pathology or symptomatology of the disease;
(iii) inhibiting the disease; for example, inhibiting a disease, condition or disorder in an individual who is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder;
(iv) ameliorating the referenced disease state, for example, ameliorating a disease, condition or disorder in an individual who is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., reversing or improving the pathology and/or symptomatology) such as decreasing the severity of disease; or
(v) eliciting the referenced biological effect. [100] As used here, the terms “treatment” and “treating” mean (i) ameliorating the referenced disease state, condition, or disorder (or a symptom thereof), such as, for example, ameliorating a disease, condition or disorder in an individual who is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., reversing or improving the pathology and/or symptomatology) such as decreasing the severity of disease or symptom thereof, or inhibiting the progression of disease; or (ii) eliciting the referenced biological effect (e.g., inhibiting inflammasome formation or function, or inhibition of IL-1 b).
Methods of Preparation
[101] Many general references providing commonly known chemical synthetic schemes and conditions useful for synthesizing the disclosed compounds are available (see, e.g., Smith and March, March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, Fifth Edition, Wiley-lnterscience, 2001; or Vogel, A Textbook of Practical Organic Chemistry, Including Qualitative Organic Analysis, Fourth Edition, New York: Longman, 1978).
[102] Compounds as described herein can be purified by any of the means known in the art, including chromatographic means, such as HPLC, preparative thin layer chromatography, flash column chromatography and ion exchange chromatography. Any suitable stationary phase can be used, including normal and reversed phases as well as ionic resins. Most typically the disclosed compounds are purified via silica gel and/or alumina chromatography. See, e.g., Introduction to Modern Liquid Chromatography, 2nd Edition, ed. L. R. Snyder and J. J.

The protecting groups may be removed at a convenient subsequent stage using methods known from the art.
[104] A “leaving group” as used herein refers to a moiety of a reactant that is displaced from the first reactant in the chemical reaction. A comprehensive list of suitable leaving groups can be found in J. March, Advanced Organic Chemistry, John Wiley and Sons, N.Y. (2013). Examples of suitable leaving groups include, but are not limited to, halogen (such as Cl or Br), acetoxy, and sulfonyloxy groups (such as methyl sulfonyloxy, trifluoromethylsulfonyloxy (“triflate”), p- toluenesulfonyloxy (“tosylate”)).
[105] The compounds disclosed herein can be made using procedures familiar to the person of ordinary skill in the art and as described herein, for example in Schemes 1-5. One of skill in the art can adapt the reaction sequences of schemes and examples as provided herein to fit the desired target molecule. Of course, in certain situations one of skill in the art will use different reagents to affect one or more of the individual steps or to use protected versions of certain of the substituents. Additionally, one skilled in the art would recognize that compounds of the disclosure can be synthesized using different routes altogether. For example, the person of ordinary skill in the art may adapt the procedures described herein and/or other procedures familiar to the person of ordinary skill in the art to make the compounds described herein.

Biological Methods
[144] Cell Culture: The human monocytic THP-1 cell line was purchased from ATCC (TIB-202). The human monocytic THP-1 ASC-GFP reporter cell line was purchased from Invivogen (thp- ascgfp). Cells were maintained in RPMI media supplemented 10% fetal bovine serum and 100 units of penicillin and streptomycin per ml_ at a cell density of 2-8 x 105 cells/mL
[145] Human peripheral blood mononuclear cells were isolated from whole blood using Lymphoprep™ density gradient according to the manufacturer’s instructions. PBMCs were used fresh.
[146] PMA differentiation of THP-1 cells: For ASC Spec assays, the human monocytic cell line THP-1 ASC-GFP cells were differentiated into a macrophage-like phenotype using Phorbol 12- myristate 13-acetate (PMA). THP-1 cells were suspended at a density of 1-2 x 106 cells/mL and supplemented with 100 ng/mL PMA. One hundred thousand cells were seeded into each well of a 96 well plate and incubated for 72 hours. Adherent cells were washed three times with PMA free THP-1 media, then cells were rested for 24 hours in PMA free media.
[147] NLRP3 Inflammasome and pyroptosis assay in THP-1 Cells: THP-1 cells were primed with 300 ng/mL of ultra-pure LPS. One hour later, cells were treated as indicated in figure legend. Three hours post-LPS prime, the NLRP3 inflammasome was activated with 10 mM Nigericin. Two hours later, supernatants were collected and analyzed for IL-1 b by ELISA. Pyroptotic cell death was assessed by MTT assay as described below. [148] Cytotoxicity Assay: THP-1 or PBMCs were treated with a dose titration of the indicated compound for 5 hours after which cell viability was assessed by MTT assay, as described below.
[149] MTT Cell Viability Assay: MTT reagent (0.6 mg/mL in THP-1 culture media) was prepared and 150 mI_ was added to each well. After 1-2 hours, cells were centrifuged at 500g for 5 minutes to pellet cells and crystals. Supernatants were removed, and formazan crystals were dissolved in 100 mI_ of isopropanol. Cell viability was assessed by measuring optical density at 560 nm, with a reference wavelength of 670 nm. Viability is expressed as percent signal relative to wells containing untreated cells.
[150] Cell Free Inflammasome Assay: Cell free inflammasome activation and Caspase-1 cleavage was assessed as described previously. Briefly, lysates were prepared from THP-1 by hypotonic lysis to a final protein concentration > 7 mg/mL. Lysates were pretreated for 20 minutes with a final concentration of 1 mM of the indicated compound on ice. Inflammasome activation was induced by incubating samples for 60 minutes at 30°C. Inflammasome activity was assessed through monitoring Caspase-1 cleavage by Western blot.
[151] NLRP3 Inflammasome activation in PBMCs: 2 x 105 freshly isolated PBMCs were primed with 300 ng/mL LPS for 1 hour, then treated with a dose titration of the indicated compounds for an additional 2 hours. The NLRP3 inflammasome was then activated by treating cells with 10 mM nigericin for 2 hours. Inflammasome activity was assessed by IL-1 b ELISA according to manufacturer’s instructions.
[152] AIM2 Inflammasome activation in PBMCs: 2 x 105 freshly isolated PBMCs were transfected with poly dA:dT (100 ng/well) using Lipofectamine 2000 (1 pL/well) according to the manufacturer’s instructions in order to activate the AIM2 inflammasome. One hour later, cells were treated with a dose titration of the indicated compounds for an additional 17 hours. Inflammasome activity was assessed by IL-1 b ELISA according to manufacturer’s instructions.
[153] NLRP1 Inflammasome activation in PBMCs: 2 x 105 freshly isolated PBMCs were treated with 10 mM Talabostat, a constitutive repressor of the NLRP1 inflammasome. One hour later, cells were treated with a dose titration of the indicated compounds for an additional 17 hours. Inflammasome activity was assessed by IL-1 b ELISA according to manufacturer’s instructions.
[154] NLRC4 Inflammasome activation PBMCs: 2 x 105 freshly isolated PBMCs were transfected with bacterial flagellin protein (100 ng/well) using Lipofectamine 2000 (1 pL/well) according to the manufacturer’s instructions in order to activate the NLRC4 inflammasome. One hour later, cells were treated with a dose titration of the indicated compounds for an additional 17 hours. Inflammasome activity was assessed by IL-1 b ELISA according to manufacturer’s instructions.
Example 4: Inhibition of Caspase-1 Processing in Cell Free Inflammasome Assay
[155] Inflammasome spontaneously assemble at 30 °C in THP-1 cell lysates with sufficient protein concentrations. This processing is dependent on ASC oligomerization. The indicated compounds, or vehicle control, were added to THP-1 lysates at a final concentration of 1 mM for 20 minutes prior to inflammasome activation. Samples were incubated for 60 minutes at 30°C to activate the inflammasome. Activation of Caspase-1 (Casp-1 ) through autoproteolytic cleavage was assessed by Western blot. Disappearance of full length Casp-1, along with increased cleaved Casp-1 in the untreated and vehicle control lanes indicates inflammasome activation. As shown in FIG. 1, compound 2 significantly inhibited the conversion of full-length Casp-1 into its active, cleaved form.
Example 5: Cellular Activity Assays
[156] The properties of each compound were assayed in a variety of cellular assays using THP- 1 human monocytic cells:
[157] Cytotoxicity was assessed by treating THP-1 cells with a dose titration of the indicated compound for 5 hours, after which cell viability was assessed by MTT assay.
[158] Inflammasome inhibition was assayed in THP-1 cells primed with LPS, then treated with a dose titration of the indicated compound for 2 hours prior to NLRP3 inflammasome activation with Nigericin. IL-1 b was assessed in cell supernatants by ELISA to monitor inflammasome activation. Simultaneously, an MTT assay was performed on the cells assess Pyroptosis, a form of inflammasome dependent inflammatory cell death.
[159] ASC oligomerization was monitored using an ASC-GFP THP-1 reporter cell line. Upon inflammasome activation, ASC polymerizes and forms a single large ‘Spec’ per cell. By tagging ASC with GFP these ‘Specs’ are readily observable and the percentage of inflammasome containing cells can be assessed. THP-1 ASC-GFP cells were differentiated using PMA overnight, then rested in PMA-free media for one day. Cells were treated with a dose titration of the indicated drug 2 hour prior to NLRP3 inflammasome activation using nigericin. Forty-five minutes after nigericin treatment cells were fixed in 2% paraformaldehyde and imaged on a fluorescent microscope. The percentage of ASC-GFP Spec positive cells per field was quantified.
