Description:
INHIBITORS OF NEK7 KINASE BACKGROUND Technical Field Embodiments of the present disclosure are generally directed to compounds and methods for their preparation and use as therapeutic or prophylactic agents, for example for treatment of inflammation. Description of the Related Art Inflammasomes are multi-protein complexes whose activation plays a central role in innate immunity and inflammation. To date, four inflammasomes have been described: NLRP1, NLRC4, NLRP3, and AIM2. The NLRP3 inflammasome is composed of NLRP3, ASC, and caspase-1. Its activation results in the activation of caspase-1 which promotes the secretion of IL-1β and IL-18, cytokines that mediate inflammation in animal disease models of several autoimmune diseases, myocardial infarction, metabolic syndromes, inflammatory bowel disease, and macrophage activation syndrome. NEK7 is a member of the family of NIMA-related kinases (NEKs) that act as NLRP3-binding proteins to regulate its oligomerization and activation. NEK7 is a serine/threonine kinase essential for mitotic entry, cell cycle progression, cell division, and mitotic progression. It is expressed in a variety of tissues such as the brain, heart, lung, liver, and spleen. Overexpression of NEK7 induces the production of abnormal cells, which has an intimate connection to tumors, such as retinoblastoma, gallbladder cancer and carcinoma of the head and neck. A great number of inhibitors have been widely used to disturb effector signaling pathways, involving IL-1β or IL-18 without abolishing the inflammation response. Inhibitors of NLRP3 inflammasome activation that block the NLRP3-NEK7 interaction can have therapeutic or prophylactic activity in several human diseases, such as type 2 diabetes (T2D), atherosclerosis, gout, and neurodegenerative diseases. However, the exact mechanism of the NLRP-3-NEK7 interaction is not well understood. Accordingly, there is a need to develop inhibitors that will directly target NEK7 to affect the inflammatory response modulated by the NLRP3 inflammasome in several pathological diseases, such as gout, atherosclerosis, Type 2 diabetes, metabolic syndrome, macular degeneration, Alzheimer’s disease, multiple sclerosis, and inflammatory bowel disease. Embodiments of the present disclosure fulfill this need and provide further related advantages.

The term "effective amount" or "therapeutically effective amount" refers to that amount of a compound described herein that is sufficient to effect the intended application including but not limited to disease treatment, as defined below. The therapeutically effective amount may vary depending upon the intended treatment application (in vivo), or the subject and disease condition being treated, e.g., the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. The term also applies to a dose that will induce a particular response in target cells, e.g., reduction of platelet adhesion and/or cell migration. The specific dose will vary depending on the particular compounds chosen, the dosing regimen to be followed, whether it is administered in combination with other compounds, timing of administration, the tissue to which it is administered, and the physical delivery system in which it is carried. As used herein, "treatment" or "treating" refer to an approach for obtaining beneficial or desired results with respect to a disease, disorder or medical condition including but not limited to a therapeutic effect and/or a prophylactic effect. By therapeutic benefit is meant eradication or amelioration of the underlying disorder being treated. Also, a therapeutic benefit is achieved with the eradication or amelioration of one or more of the physiological symptoms associated with the underlying disorder such that an improvement is observed in the subject, notwithstanding that the subject may still be afflicted with the underlying disorder. A prophylactic effect includes delaying or eliminating the appearance of a disease or condition, delaying or eliminating the onset of symptoms of a disease or condition, slowing, halting, or reversing the progression of a disease or condition, or any combination thereof. In certain embodiments, for prophylactic benefit, the compositions are administered to a subject at risk of developing a particular disease, or to a subject reporting one or more of the physiological symptoms of a disease, even though a diagnosis of this disease may not have been made. The term "co-administration," "administered in combination with," and their grammatical equivalents, as used herein, encompass administration of two or more agents to an animal, including humans, so that both agents and/or their metabolites are present in the subject at the same time. Co-administration includes simultaneous administration in separate compositions, administration at different times in separate compositions, or administration in a composition in which both agents are present. "Pharmaceutically acceptable salt" includes both acid and base addition salts. "Pharmaceutically acceptable acid addition salt" refers to those salts which retain the biological effectiveness of the free bases, which are biologically tolerable, or otherwise biologically suitable for administration to the subject. See, generally, S.M. Berge, et al., "Pharmaceutical Salts", J. Pharm. Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley- VCH and VHCA, Zurich, 2002.

"Pharmaceutically acceptable base addition salt" refers to those salts which retain the biological effectiveness of the free acids, which are biologically tolerable, or otherwise biologically suitable for administration to the subject. See, generally, S.M. Berge, et al., "Pharmaceutical Salts", J. Pharm. Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley- VCH and VHCA, Zurich, 2002. Preferred pharmaceutically acceptable base addition salts are those that are pharmacologically effective and suitable for contact with the tissues of patients without undue toxicity, irritation, or allergic response. Pharmaceutically acceptable base addition salts are prepared from addition of an inorganic base or an organic base to the free acid. Salts derived from inorganic bases include, but are not limited to, the sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like. Preferred inorganic salts are the ammonium, sodium, potassium, calcium, and magnesium salts. Salts derived from organic bases include, but are not limited to, salts of primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, such as ammonia, isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, diethanolamine, ethanolamine, deanol, 2-dimethylaminoethanol, 2-diethylaminoethanol, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, hydrabamine, choline, betaine, benethamine, benzathine, ethylenediamine, glucosamine, methylglucamine, theobromine, triethanolamine, tromethamine, purines, piperazine, piperidine, N-ethylpiperidine, polyamine resins and the like. Particularly preferred organic bases are isopropylamine, diethylamine, ethanolamine, trimethylamine, dicyclohexylamine, choline and caffeine. In some embodiments, pharmaceutically acceptable salts include quaternary ammonium salts such as quaternary amine alkyl halide salts (e.g., methyl bromide). The terms "antagonist" and "inhibitor" are used interchangeably, and they refer to a compound having the ability to inhibit a biological function of a target protein, whether by inhibiting the activity or expression of the protein, such as NLRP3 inflammasome or NEK7 or the association of NLRP3 inflammasome – NEK7. Accordingly, the terms "antagonist" and "inhibitors" are defined in the context of the biological role of the target protein. While preferred antagonists herein specifically interact with (e.g., bind to) the target, compounds that inhibit a biological activity of the target protein by interacting with other members of the signal transduction pathway of which the target protein is a member are also specifically included within this definition. A preferred biological activity inhibited by an antagonist is associated with the development, growth, or spread of a tumor. The term "agonist" as used herein refers to a compound having the ability to initiate or enhance a biological function of a target protein, whether by inhibiting the activity or expression of the target protein. Accordingly, the term "agonist" is defined in the context of the biological role of the target polypeptide. While preferred agonists herein specifically interact with (e.g., bind to) the target, compounds that initiate or enhance a biological activity of the target polypeptide by interacting with other members of the signal transduction pathway of which the target polypeptide is a member are also specifically included within this definition. "Signal transduction" is a process during which stimulatory or inhibitory signals are transmitted into and within a cell to elicit an intracellular response. The term "selective inhibition" or "selectively inhibit" refers to a biologically active agent refers to the agent’s ability to preferentially reduce the target signaling activity as compared to off-target signaling activity, via direct or indirect interaction with the target. "Subject" refers to an animal, such as a mammal, for example a human. The methods described herein can be useful in both human therapeutics and veterinary applications. In some embodiments, the subject is a mammal, and in some embodiments, the subject is human. "Mammal" includes humans and both domestic animals such as laboratory animals and household pets (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildlife and the like. "Prodrug" is meant to indicate a compound that may be converted under physiological conditions or by solvolysis to a biologically active compound described herein (e.g., compounds of Structure (I)). Thus, the term "prodrug" refers to a precursor of a biologically active compound that is pharmaceutically acceptable. In some aspects, a prodrug is inactive when administered to a subject, but is converted in vivo to an active compound, for example, by hydrolysis. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see, e.g., Bundgard, H., Design of Prodrugs (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam). A discussion of prodrugs is provided in Higuchi, T., et al., "Pro-drugs as Novel Delivery Systems," A.C.S. Symposium Series, Vol. 14, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated in full by reference herein. The term "prodrug" is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a mammalian subject. Prodrugs of an active compound, as described herein, are typically prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound. Prodrugs include compounds wherein a hydroxy, amino or thiol group is bonded to any group that, when the prodrug of the active compound is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of a hydroxy functional group, or acetamide, formamide and benzamide derivatives of an amine functional group in the active compound and the like. The term "in vivo" refers to an event that takes place in a subject’s body. Embodiments disclosed herein are also meant to encompass all pharmaceutically acceptable compounds of Structure (I). Certain embodiments are also meant to encompass the in vivo metabolic products of the disclosed compounds. Such products may result from, for example, the oxidation, reduction, hydrolysis, amidation, esterification, and the like of the administered compound, primarily due to enzymatic processes. Accordingly, embodiments include compounds produced by a process comprising administering a compound of this disclosure to a mammal for a period of time sufficient to yield a metabolic product thereof. Such products are typically identified by administering a radiolabeled compound of the disclosure in a detectable dose to an animal, such as rat, mouse, guinea pig, monkey, or to human, allowing sufficient time for metabolism to occur, and isolating its conversion products from the urine, blood or other biological samples. "Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. Often crystallizations produce a solvate of the compounds disclosed herein. As used herein, the term "solvate" refers to an aggregate that comprises one or more compounds of the disclosure with one or more molecules of solvent. In some embodiments, the solvent is water, in which case the solvate is a hydrate. Alternatively, in other embodiments, the solvent is an organic solvent. Thus, the compounds of the present disclosure may exist as a hydrate, including a monohydrate, dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate and the like, as well as the corresponding solvated forms. In some aspects, the compounds of the disclosure are a true solvate, while in other cases, the compounds of the disclosure merely retain adventitious water or is a mixture of water plus some adventitious solvent. "Optional" or "optionally" means that the subsequently described event of circumstances may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, "optionally substituted aryl" means that the aryl radical may or may not be substituted and that the description includes both substituted aryl radicals and aryl radicals having no substitution. A "pharmaceutical composition" refers to formulations of compounds of the disclosure and a medium generally accepted in the art for the delivery of compounds of the disclosure to mammals, e.g., humans. Such a medium includes all pharmaceutically acceptable carriers, diluents or excipients therefor. "Pharmaceutically acceptable carrier, diluent or excipient" includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye/colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier. A "stereoisomer" refers to a compound made up of the same atoms bonded by the same bonds but having different three-dimensional structures, which are not interchangeable. The present disclosure contemplates various stereoisomers and mixtures thereof and includes "enantiomers", which refers to two stereoisomers whose molecules are non-superimposable mirror images of one another. The compounds of the disclosure (i.e., compounds of Structure (I)) or their pharmaceutically acceptable salts may contain one or more centers of geometric asymmetry and may thus give rise to stereoisomers such as enantiomers, diastereomers, and other stereoisomeric forms that are defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids. Embodiments thus include all such possible isomers, as well as their racemic and optically pure forms. Optically active (+) and (-), (R)- and (S)-, or (D)- and (L)- isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, for example, chromatography and fractional crystallization. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC). When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included. Embodiments of the present disclosure include all manner of rotamers and conformationally restricted states of a compound of the invention. Atropisomers, which are stereoisomers arising because of hindered rotation about a single bond, where energy differences due to steric strain or other contributors create a barrier to rotation that is high enough to allow for isolation of individual conformers, are also included. As an example, certain compounds of the disclosure may exist as mixtures of atropisomers or purified or enriched for the presence of one atropisomer. In some embodiments, the compounds of Structure (I) are a mixture of enantiomers or diastereomers. In other embodiments, the compounds of Structure (I) are substantially one enantiomer or diastereomer. A "tautomer" refers to a proton shift from one atom of a molecule to another atom of the same molecule. Embodiments thus include tautomers of the disclosed compounds. The chemical naming protocol and structure diagrams used herein are a modified form of the I.U.P.A.C. nomenclature system, using the ACD/Name Version 9.07 software program and/or ChemDraw Profesional Version 17.0.0.206 software naming program (CambridgeSoft). For complex chemical names employed herein, a substituent group is typically named before the group to which it attaches. For example, cyclopropylethyl comprises an ethyl backbone with a cyclopropyl substituent. Except as described below, all bonds are identified in the chemical structure diagrams herein, except for all bonds on some carbon atoms, which are assumed to be bonded to sufficient hydrogen atoms to complete the valency.

It is understood that in the present description, combinations of substituents and/or variables of the depicted formulae are permissible only if such contributions result in stable compounds. In an additional embodiment, various compounds of the disclosure which exist in free base or acid form can be converted to their pharmaceutically acceptable salts by treatment with the appropriate inorganic or organic base or acid by methods known to one skilled in the art. Salts of the compounds of the disclosure can be converted to their free base or acid form by standard techniques. Methods for producing the compounds described herein is provided below. In general, starting components may be obtained from sources such as Sigma Aldrich, Lancaster Synthesis, Inc., Maybridge, Matrix Scientific, TCI, and Fluorochem USA, etc. or synthesized according to sources known to those skilled in the art (see, for example, Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 5th edition (Wiley, December 2000)) or prepared as described herein. The following General Reaction Schemes illustrate exemplary methods for preparation of compounds of Structure (I): or pharmaceutically acceptable salts, stereoisomers or prodrug thereof, wherein each of A, X, Y, R 1 , R 2 , R 3 and R 4 are as defined herein. General Reaction Scheme 1 The following General Reaction Scheme, wherein X 1 is halogen, and X, R 1 , R 2 , and A have the meanings described herein, illustrates examples of methods of making the amine intermediates B: As shown in General Reaction Scheme 1, functionalization of the pyrazolopyrimidine with an alkyl or aryl boronic acid or an appropriate electrophile in presence of a base affords intermediate A which can then be subject to palladium catalyzed arylation (followed as needed by a reduction step) to form amine intermediate B. General Reaction Scheme 2 The following General Reaction Scheme illustrates examples of methods of making the carbamate intermediates C: As shown in General Reaction Scheme 2, intermediates C can be prepared in the presence of a base by reaction of phenyl chloroformates and the indicated heteroaryl amine (an amine-substituted analogue of R 3 ). General Reaction Scheme 2 depicts preparation of compounds wherein R 4 is H; however, compounds wherein R 4 is other than H can be prepared by similar methods by installing R 4 after preparation of intermediate I or by using an appropriately substituted heteroaryl amine. General Reaction Scheme 3 The following General Reaction Scheme illustrates examples of methods of making the compounds of Structure (I): Intermediates B and intermediates C are treated with a base, such as trimethylamine, in THF to afford the compounds of Structure (I). General Reaction Scheme 4 The following General Reaction Scheme illustrates examples of methods of making the compounds of Structure (I): Intermediate B is reacted with phenyl chloroformate under appropriate conditions to yield Intermediate C. Intermediate C is then coupled with the amine using a suitable base (e.g., trimethylamine, DIPEA, DMAP, and the like) in THF to afford the compounds of Structure (I). Any of the above reaction schemes can be modified at any step to add and/or modify a substituent or change the order of the steps as appropriate during any stage of the overall synthesis of desired compounds. For example, one of ordinary skill in the art will readily understand that a carbamate analogue of Intermediate B could alternatively be prepared and reacted with an amine analogue of R 3 to prepare compounds of Structure (I). It will also be appreciated by those skilled in the art that in the processes for preparing the compounds described herein the functional groups of intermediate compounds may need to be protected by suitable protecting groups. Such functional groups include, but are not limited to, hydroxy, amino, mercapto and carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl or diarylalkylsilyl (for example, t-butyldimethylsilyl, t-butyldiphenylsilyl or trimethylsilyl), tetrahydropyranyl, benzyl, and the like. Suitable protecting groups for amino, amidino and guanidino include t-butoxycarbonyl, benzyloxycarbonyl, and the like. Suitable protecting groups for mercapto include -C(O)-R" (where R" is alkyl, aryl or arylalkyl), p-methoxybenzyl, trityl and the like. Suitable protecting groups for carboxylic acid include alkyl, aryl or arylalkyl esters. Protecting groups are optionally added or removed in accordance with standard techniques, which are known to one skilled in the art and as described herein. The use of protecting groups is described in detail in Green, T.W. and P.G.M. Wutz, Protective Groups in Organic Synthesis (1999), 3rd Ed., Wiley. As one of skill in the art would appreciate, the protecting group may also be a polymer resin such as a Wang resin, Rink resin or a 2-chlorotrityl-chloride resin. It will also be appreciated by those skilled in the art, although such protected derivatives of compounds of this disclosure may not possess pharmacological activity as such, they may be administered to a mammal and thereafter metabolized in the body to form compounds of the disclosure which are pharmacologically active. Such derivatives may therefore be described as "prodrugs". Prodrugs of compounds of this disclosure are included within the scope of embodiments of the invention.

When used in combination therapy, the compounds described herein are administered with the second agent simultaneously or separately. This administration in combination can include simultaneous administration of the two agents in the same dosage form, simultaneous administration in separate dosage forms, and separate administration. That is, a compound described herein and any of the agents described above can be formulated together in the same dosage form and administered simultaneously. Alternatively, a compound of the disclosure and any of the agents described above can be simultaneously administered, wherein both the agents are present in separate formulations. In another alternative, a compound of the present disclosure can be administered just followed by and any of the agents described above, or vice versa. In some embodiments of the separate administration protocol, a compound of the disclosure and any of the agents described above are administered a few minutes apart, or a few hours apart, or a few days apart. In some embodiments, the compounds of Structure (I) are administered as a mono-therapy. For identification of a signal transduction or a mechanistic pathway and for detection of interactions between various signal transduction pathways, various scientists have developed suitable models or model systems, for example cell culture models and models of transgenic animals. For the determination of certain stages in the signal transduction cascade, interacting compounds can be utilized in order to modulate the signal. The compounds of embodiments of the invention can also be used as reagents for testing NEK7-dependent signal transduction pathways in animals and/or cell culture models or in the clinical diseases mentioned in this application. The methods of embodiments of embodiments of the invention can be performed either in vitro or in vivo. The susceptibility of a particular cell to treatment with the compounds of Structure (I) can be particularly determined by in-vitro tests, whether in the course of research or clinical application. Typically, a culture of the cell is combined with a compound at various concentrations for a period of time which is sufficient to allow the active agents to inhibit NEK7 activity, usually between about one hour and one week. In-vitro treatment can be carried out using cultivated cells from a biopsy sample or cell line. In some embodiments, the IC50 of the compounds of Structure (I) to inhibit NEK7 was determined by the concentration of the compound required to inhibit 50% of the activity of the NEK kinase. The compounds of Structure (I) exhibited potency values of IC50 of less than about 5 mM, preferably less than about 1 mM and even more preferably less than about 0.100 mM as described in further detail in the Examples. The examples and preparations provided below further illustrate and exemplify the compounds of the present disclosure and methods of preparing and testing such compounds. It is to be understood that the scope of the present disclosure is not limited in any way by the scope of the following examples and preparations. In the following examples, and throughout the specification and claims, molecules with a single stereocenter, unless otherwise noted, exist as a racemic mixture. Those molecules with two or more stereocenters, unless otherwise noted, exist as a racemic mixture of diastereomers. Single enantiomers/diastereomers may be obtained by methods known to those skilled in the art. EXAMPLES The following examples are provided for exemplary purposes. General Procedures All proton NMR experiments were recorded on a Bruker NEO Spectrometer equipped with a BBFO probe at 400 MHz. Deuterated solvents contained less than 0.05% v/v tetramethylsilane which was used as the reference signal (set at 0.00 ppm). When deuterated solvents did not contain tetramethylsilane, the residual nondeuterated solvent peaks were used as a reference signal, as per published guidelines (J. Org. Chem. 1997, 62(21), 7512-7515). Chemical shifts are expressed in parts per million (ppm, δ units). Coupling constants are in hertz (Hz). Splitting patterns describe apparent multiplicities and are designated as s (singlet), d (doublet), t (triplet), q (quartet), m (multiplet), qt (quintuplet) or brs (broad singlet). LC/MS analyses were performed on an Agilent Technologies UHPLC 1290 Infinity II with a G6125 MS detector. Microwave reactions were conducted with a Monowave 300 by Anton Paar GmbH using standard protocols. NEK7 Enzymatic Assay Casein substrate (from bovine milk, hydrolyzed and partially dephosphorylated mixture of α, β and κ caseins, obtained from Sigma Aldrich, catalogue # C4765, diluted in distilled water to a final concentration of 1 mg/mL) and full-length recombinant human NEK7 (expressed by baculovirus in Sf9 insect cells using a N-terminal GST tag, obtained from SignalChem, catalogue # N09-10G, 0.1 μg/μL) were mixed in assay buffer (20 mM Hepes pH 7.5, 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO). Compounds of interest (serial 3-fold dilution in DMSO from 10 µM to 0.5 nM) or vehicle (1% DMSO) were dispensed into the kinase reaction mixture by Acoustic technology (Echo550; nanoliter range). After incubation at room temperature for 20 minutes, the kinase reaction was initiated by addition of [ 33 P]- ATP (specific activity 10 µCi/µl) and the mixture was incubated at room temperature for 2 hours. The reaction was then stopped by spotting the reaction mixture on strips of phosphocellulose P81 paper. Following washing, the radioactivity of the P81 paper was measured and kinase activity data were expressed as the percent remaining kinase activity in test samples compared to vehicle reactions. IC50 values and curve fits were obtained using Prism (GraphPad Software). IL-1β Release Assay Approximately 1.5 million THP-1 cells were plated in each well of a 6-well TC plate and incubated with 40 nM PMA in RPMI (10% FBS, 1% Penstrep) for 24 hours. The media was then removed and cells were rested in RPMI (10% FBS, 1% Penstrep) for 24 hours after which time the media was removed and cells were pre-treated for 2 hours with various concentrations of compounds of interest (typically serial 3-fold dilution in RPMI + 5% FBS, concentrations ranging from 1 µM to 0.5 nM) in RPMI (5% FBS). The media was again removed and cells were incubated with 250 ng/mL LPS and compounds of interest (concentrations as above) in RMPI (5% FBS) for 2 hours. The media was removed for a last time and cells were incubated with 20 µM nigericin and compounds of interest (concentrations as above) in Opti-MEM for 30 minutes. Cell media was then collected and the amount of cleaved IL-1β was determined using a JESS instrument (Protein Simple) and standard protocols. Cleaved Il-1β antibody was obtained from Cell Signaling (catalogue #83186S) and was used at 1:20 dilution in antibody diluent 2. Protein Simple 1x anti-Rabbit HRP secondary antibody was used along with Protein Simple luminol and peroxide for chemiluminescent detection. Primary antibody incubation time was increased from 30 minutes to 60 minutes.
