Description
TECHNICAL FIELD

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt, and/or hydrate, and/or cocrystal, and/or prodrug, and/or tautomer, and/or drug combination of the compound) that inhibit (e.g., antagonize) Stimulator of Interferon Genes (STING). Said chemical entities are useful, e.g., for treating a condition, disease or disorder in which increased (e.g., excessive) STING activation (e.g., STING signaling) contributes to the pathology and/or symptoms and/or progression of the condition, disease or disorder (e.g., cancer) in a subject (e.g., a human). This disclosure also features compositions containing the same as well as methods of using and making the same.


BACKGROUND

STING, also known as transmembrane protein 173 (TMEM173) and MPYS/MITA/ERIS, is a protein that in humans is encoded by the TMEM173 gene. STING has been shown to play a role in innate immunity. STING induces type I interferon production when cells are infected with intracellular pathogens, such as viruses, mycobacteria and intracellular parasites. Type I interferon, mediated by STING, protects infected cells and nearby cells from local infection in an autocrine and paracrine manner.


The STING pathway is pivotal in mediating the recognition of cytosolic DNA. In this context, STING, a transmembrane protein localized to the endoplasmic reticulum (ER), acts as a second messenger receptor for 2′, 3′ cyclic GMP-AMP (hereafter cGAMP), which is produced by cGAS after dsDNA binding. In addition, STING can also function as a primary pattern recognition receptor for bacterial cyclic dinucleotides (CDNs) and small molecule agonists. The recognition of endogenous or prokaryotic CDNs proceeds through the carboxy-terminal domain of STING, which faces into the cytosol and creates a V-shaped binding pocket formed by a STING homodimer. Ligand-induced activation of STING triggers its re-localization to the Golgi, a process essential to promote the interaction of STING with TBK1. This protein complex, in turn, signals through the transcription factors IRF-3 to induce type I interferons (IFNs) and other co-regulated antiviral factors. In addition, STING was shown to trigger NF-κB and MAP kinase activation. Following the initiation of signal transduction, STING is rapidly degraded, a step considered important in terminating the inflammatory response.


Excessive activation of STING is associated with a subset of monogenic autoinflammatory conditions, the so-called type I interferonopathies. Examples of these diseases include a clinical syndrome referred to as STING-associated vasculopathy with onset in infancy (SAVI), which is caused by gain-of-function mutations in TMEM173 (the gene name of STING). Moreover, STING is implicated in the pathogenesis of Aicardi-Goutieres Syndrome (AGS) and genetic forms of lupus. As opposed to SAVI, it is the dysregulation of nucleic acid metabolism that underlies continuous innate immune activation in AGS. Apart from these genetic disorders, emerging evidence points to a more general pathogenic role for STING in a range of inflammation-associated disorders such as systemic lupus erythematosus, rheumatoid arthritis and cancer. Thus, small molecule-based pharmacological interventions into the STING signaling pathway hold significant potential for the treatment of a wide spectrum of diseases

The term “saturated” as used in this context means only single bonds present between constituent ring atoms and other available valences occupied by hydrogen and/or other substituents as defined herein.


The term “heterocycloalkenyl” as used herein means partially unsaturated cyclic ring system with 3-16 ring atoms (e.g., 5-8 membered monocyclic, 8-12 membered bicyclic, or 11-14 membered tricyclic ring system) having 1-3 heteroatoms if monocyclic, 1-6 heteroatoms if bicyclic, or 1-9 heteroatoms if tricyclic or polycyclic, said heteroatoms selected from O, N, or S (e.g., carbon atoms and 1-3, 1-6, or 1-9 heteroatoms of N, O, or S if monocyclic, bicyclic, or tricyclic, respectively), wherein 0, 1, 2 or 3 atoms of each ring may be substituted by a substituent. Examples of heterocycloalkenyl groups include, without limitation, tetrahydropyridyl, dihydropyrazinyl, dihydropyridyl, dihydropyrrolyl, dihydrofuranyl, dihydrothiophenyl. As partially unsaturated cyclic groups, heterocycloalkenyl groups may have any degree of unsaturation provided that one or more double bonds is present in the ring, none of the rings in the ring system are aromatic, and the heterocycloalkenyl group is not fully saturated overall. Heterocycloalkenyl may include multiple fused and/or bridged and/or spirocyclic rings.


As used herein, when a ring is described as being “aromatic”, it means said ring has a continuous, delocalized π-electron system. Typically, the number of out of plane π-electrons corresponds to the Hückel rule (4n+2). Examples of such rings include: benzene, pyridine, pyrimidine, pyrazine, pyridazine, pyridone, pyrrole, pyrazole, oxazole, thioazole, isoxazole, isothiazole, and the like.


As used herein, when a ring is described as being “partially unsaturated”, it means said ring has one or more additional degrees of unsaturation (in addition to the degree of unsaturation attributed to the ring itself, e.g., one or more double or triple bonds between constituent ring atoms), provided that the ring is not aromatic. Examples of such rings include: cyclopentene, cyclohexene, cycloheptene, dihydropyridine, tetrahydropyridine, dihydropyrrole, dihydrofuran, dihydrothiophene, and the like.


For the avoidance of doubt, and unless otherwise specified, for rings and cyclic groups (e.g., aryl, heteroaryl, heterocyclyl, heterocycloalkenyl, cycloalkenyl, cycloalkyl, and the like described herein) containing a sufficient number of ring atoms to form bicyclic or higher order ring systems (e.g., tricyclic, polycyclic ring systems), it is understood that such rings and cyclic groups encompass those having fused rings, including those in which the points of fusion are located (i) on adjacent ring atoms (e.g., [x.x.0] ring systems, in which 0 represents a zero atom bridge (e.g.,




embedded image


(ii) a single ring atom (spiro-fused ring systems) (e.g.,




embedded image


or (iii) a contiguous array of ring atoms (bridged ring


systems having all bridge lengths >0) (e.g.,

In addition, atoms making up the compounds of the present embodiments are intended to include all isotopic forms of such atoms. Isotopes, as used herein, include those atoms having the same atomic number but different mass numbers. By way of general example and without limitation, isotopes of hydrogen include tritium and deuterium, and isotopes of carbon include 13C and 14C.


In addition, the compounds generically or specifically disclosed herein are intended to include all tautomeric forms. Thus, by way of example, a compound containing the moiety:

Similarly, a pyridinyl or pyrimidinyl moiety that is described to be optionally substituted with hydroxyl encompasses pyridone or pyrimidone tautomeric forms.


Some non-limiting exemplified compounds of the formulae described herein include one or more stereogenic carbon atoms. This disclosure provides examples of stereoisomer mixtures (e.g., racemic and non-racemic mixture of enantiomers; mixture of diastereomers, meso compounds). This disclosure also describes and exemplifies methods for separating individual components of said stereoisomer mixtures (e.g., resolving the enantiomers of a racemic mixture). In some instances, stereoisomers are graphically depicted using hashed and solid wedge three-dimensional representations. Unless otherwise indicated with “(R)” or “(S)” labels, the hashed and solid wedge three-dimensional representation are intended to convey relative stereochemistry only. Likewise, and unless otherwise indicated, reaction schemes showing resolution of a racemic mixture, the above-mentioned representations are intended only to convey that the constituent enantiomers were resolved in enantiopure pure form (about 98% ee or greater) and are not intended to disclose or imply any correlation between absolute configuration and order of elution.


The definitions of certain variables herein include -L1-L2-Rh and -L3-L4-Ri. For avoidance of doubt, when a variable is -L1-L2-Rh; -L1 is a bond; and -L2 is a bond, then said variable is —Rh that is connected to the rest of the compound via a single bond. As a non-limiting example, when one occurrence of Rb is -L1-L2-Rh; -L1 is a bond; and -L2 is a bond, then said occurrence of Rb is —Rh that is connected to the rest of the compound via a single bond. Similarly, when a variable is -L3-L4-Ri; -L3 is a bond; and -L4 is a bond, then said variable is —R that is connected to the rest of the compound via a single bond.


The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features and advantages of the invention will be apparent from the description and drawings, and from the claims.

Pharmaceutical Compositions and Administration


General


In some embodiments, a chemical entity (e.g., a compound that inhibits (e.g., antagonizes) STING, or a pharmaceutically acceptable salt, and/or hydrate, and/or cocrystal, and/or drug combination thereof) is administered as a pharmaceutical composition that includes the chemical entity and one or more pharmaceutically acceptable excipients, and optionally one or more additional therapeutic agents as described herein.


In some embodiments, the chemical entities can be administered in combination with one or more conventional pharmaceutical excipients. Pharmaceutically acceptable excipients include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, self-emulsifying drug delivery systems (SEDDS) such as d-α-tocopherol polyethylene glycol 1000 succinate, surfactants used in pharmaceutical dosage forms such as Tweens, poloxamers or other similar polymeric delivery matrices, serum proteins, such as human serum albumin, buffer substances such as phosphates, tris, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium-chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethyl cellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, and wool fat. Cyclodextrins such as α-, β, and γ-cyclodextrin, or chemically modified derivatives such as hydroxyalkylcyclodextrins, including 2- and 3-hydroxypropyl-o-cyclodextrins, or other solubilized derivatives can also be used to enhance delivery of compounds described herein. Dosage forms or compositions containing a chemical entity as described herein in the range of 0.005% to 100% with the balance made up from non-toxic excipient may be prepared. The contemplated compositions may contain 0.001%-100% of a chemical entity provided herein, in one embodiment 0.1-95%, in another embodiment 75-85%, in a further embodiment 20-80%. Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington: The Science and Practice of Pharmacy, 22nd Edition (Pharmaceutical Press, London, U K. 2012).


Routes of Administration and Composition Components


In some embodiments, the chemical entities described herein or a pharmaceutical composition thereof can be administered to subject in need thereof by any accepted route of administration. Acceptable routes of administration include, but are not limited to, buccal, cutaneous, endocervical, endosinusial, endotracheal, enteral, epidural, interstitial, intra-abdominal, intra-arterial, intrabronchial, intrabursal, intracerebral, intracisternal, intracoronary, intradermal, intraductal, intraduodenal, intradural, intraepidermal, intraesophageal, intragastric, intragingival, intraileal, intralymphatic, intramedullary, intrameningeal, intramuscular, intraovarian, intraperitoneal, intraprostatic, intrapulmonary, intrasinal, intraspinal, intrasynovial, intratesticular, intrathecal, intratubular, intratumoral, intrauterine, intravascular, intravenous, nasal, nasogastric, oral, parenteral, percutaneous, peridural, rectal, respiratory (inhalation), subcutaneous, sublingual, submucosal, topical, transdermal, transmucosal, transtracheal, ureteral, urethral and vaginal. In certain embodiments, a preferred route of administration is parenteral (e.g., intratumoral).


Compositions can be formulated for parenteral administration, e.g., formulated for injection via the intravenous, intramuscular, sub-cutaneous, or even intraperitoneal routes. Typically, such compositions can be prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for use to prepare solutions or suspensions upon the addition of a liquid prior to injection can also be prepared; and the preparations can also be emulsified. The preparation of such formulations will be known to those of skill in the art in light of the present disclosure.


The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions; formulations including sesame oil, peanut oil, or aqueous propylene glycol; and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases the form must be sterile and must be fluid to the extent that it may be easily injected. It also should be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms, such as bacteria and fungi.


The carrier also can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), suitable mixtures thereof, and vegetable oils. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion, and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.


Sterile injectable solutions are prepared by incorporating the active compounds in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques, which yield a powder of the active ingredient, plus any additional desired ingredient from a previously sterile-filtered solution thereof.


Intratumoral injections are discussed, e.g., in Lammers, et al., “Effect of Intratumoral Injection on the Biodistribution and the Therapeutic Potential of HPMA Copolymer-Based Drug Delivery Systems” Neoplasia. 2006, 10, 788-795.


Pharmacologically acceptable excipients usable in the rectal composition as a gel, cream, enema, or rectal suppository, include, without limitation, any one or more of cocoa butter glycerides, synthetic polymers such as polyvinylpyrrolidone, PEG (like PEG ointments), glycerine, glycerinated gelatin, hydrogenated vegetable oils, poloxamers, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol Vaseline, anhydrous lanolin, shark liver oil, sodium saccharinate, menthol, sweet almond oil, sorbitol, sodium benzoate, anoxid SBN, vanilla essential oil, aerosol, parabens in phenoxyethanol, sodium methyl p-oxybenzoate, sodium propyl p-oxybenzoate, diethylamine, carbomers, carbopol, methyloxybenzoate, macrogol cetostearyl ether, cocoyl caprylocaprate, isopropyl alcohol, propylene glycol, liquid paraffin, xanthan gum, carboxy-metabisulfite, sodium edetate, sodium benzoate, potassium metabisulfite, grapefruit seed extract, methyl sulfonyl methane (MSM), lactic acid, glycine, vitamins, such as vitamin A and E and potassium acetate.


In certain embodiments, suppositories can be prepared by mixing the chemical entities described herein with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum and release the active compound. In other embodiments, compositions for rectal administration are in the form of an enema.


In other embodiments, the compounds described herein or a pharmaceutical composition thereof are suitable for local delivery to the digestive or GI tract by way of oral administration (e.g., solid or liquid dosage forms.).


Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the chemical entity is mixed with one or more pharmaceutically acceptable excipients, such as sodium citrate or dicalcium phosphate and/or: a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.


In one embodiment, the compositions will take the form of a unit dosage form such as a pill or tablet and thus the composition may contain, along with a chemical entity provided herein, a diluent such as lactose, sucrose, dicalcium phosphate, or the like; a lubricant such as magnesium stearate or the like; and a binder such as starch, gum acacia, polyvinylpyrrolidine, gelatin, cellulose, cellulose derivatives or the like. In another solid dosage form, a powder, marume, solution or suspension (e.g., in propylene carbonate, vegetable oils, PEG's, poloxamer 124 or triglycerides) is encapsulated in a capsule (gelatin or cellulose base capsule). Unit dosage forms in which one or more chemical entities provided herein or additional active agents are physically separated are also contemplated; e.g., capsules with granules (or tablets in a capsule) of each drug; two-layer tablets; two-compartment gel caps, etc. Enteric coated or delayed release oral dosage forms are also contemplated.


Other physiologically acceptable compounds include wetting agents, emulsifying agents, dispersing agents or preservatives that are particularly useful for preventing the growth or action of microorganisms. Various preservatives are well known and include, for example, phenol and ascorbic acid.


In certain embodiments the excipients are sterile and generally free of undesirable matter. These compositions can be sterilized by conventional, well-known sterilization techniques. For various oral dosage form excipients such as tablets and capsules sterility is not required. The USP/NF standard is usually sufficient.


In certain embodiments, solid oral dosage forms can further include one or more components that chemically and/or structurally predispose the composition for delivery of the chemical entity to the stomach or the lower GI; e.g., the ascending colon and/or transverse colon and/or distal colon and/or small bowel. Exemplary formulation techniques are described in, e.g., Filipski, K. J., et al., Current Topics in Medicinal Chemistry, 2013, 13, 776-802, which is incorporated herein by reference in its entirety.


Examples include upper-GI targeting techniques, e.g., Accordion Pill (Intec Pharma), floating capsules, and materials capable of adhering to mucosal walls.


Other examples include lower-GI targeting techniques. For targeting various regions in the intestinal tract, several enteric/pH-responsive coatings and excipients are available. These materials are typically polymers that are designed to dissolve or erode at specific pH ranges, selected based upon the GI region of desired drug release. These materials also function to protect acid labile drugs from gastric fluid or limit exposure in cases where the active ingredient may be irritating to the upper GI (e.g., hydroxypropyl methylcellulose phthalate series, Coateric (polyvinyl acetate phthalate), cellulose acetate phthalate, hydroxypropyl methylcellulose acetate succinate, Eudragit series (methacrylic acid-methyl methacrylate copolymers), and Marcoat). Other techniques include dosage forms that respond to local flora in the GI tract, Pressure-controlled colon delivery capsule, and Pulsincap.


Ocular compositions can include, without limitation, one or more of any of the following: viscogens (e.g., Carboxymethylcellulose, Glycerin, Polyvinylpyrrolidone, Polyethylene glycol); Stabilizers (e.g., Pluronic (triblock copolymers), Cyclodextrins); Preservatives (e.g., Benzalkonium chloride, ETDA, SofZia (boric acid, propylene glycol, sorbitol, and zinc chloride; Alcon Laboratories, Inc.), Purite (stabilized oxychloro complex; Allergan, Inc.)).


Topical compositions can include ointments and creams. Ointments are semisolid preparations that are typically based on petrolatum or other petroleum derivatives. Creams containing the selected active agent are typically viscous liquid or semisolid emulsions, often either oil-in-water or water-in-oil. Cream bases are typically water-washable, and contain an oil phase, an emulsifier and an aqueous phase. The oil phase, also sometimes called the “internal” phase, is generally comprised of petrolatum and a fatty alcohol such as cetyl or stearyl alcohol; the aqueous phase usually, although not necessarily, exceeds the oil phase in volume, and generally contains a humectant. The emulsifier in a cream formulation is generally a nonionic, anionic, cationic or amphoteric surfactant. As with other carriers or vehicles, an ointment base should be inert, stable, nonirritating and non-sensitizing.


In any of the foregoing embodiments, pharmaceutical compositions described herein can include one or more one or more of the following: lipids, interbilayer crosslinked multilamellar vesicles, biodegradeable poly(D,L-lactic-co-glycolic acid) [PLGA]-based or poly anhydride-based nanoparticles or microparticles, and nanoporous particle-supported lipid bilayers.

Example 94: N-(5,6-difluoro-1H-indol-3-yl)-N′-trans-3-((5-methylpyridin-2-yl)oxy)cyclobutyl)oxalamide (Compound 199)



embedded image


Step 1: methyl [(5,6-difluoro-1H-indol-3-yl)carbamoyl]formate

5,6-difluoro-1H-indol-3-amine hydrochloride (16.0 g, 95.2 mmol, 1.0 equiv.) and TEA (13.1 mL, 95.2 mmol, 1.0 equiv.) were dissolved in THE (250 mL) and the solution was cooled to 0° C. Then methyl oxalyl chloride (8.6 mL, 95.2 mmol, 1.0 equiv.) was added dropwise, maintaining the solution at 0° C. The reaction mixture was stirred for 2 hours at 0° C. The resulting solids were collected by filtration to give methyl [(5,6-difluoro-1Hindol-3-yl)carbamoyl]formate (16.3 g) as a yellow solid. LCMS Method CB: [M+H]+=255.


Step 2: [(5,6-difluoro-1H-indol-3-yl)carbamoyl]formic acid

Methyl [(5,6-difluoro-1H-indol-3-yl)carbamoyl]formate (5.0 g, 19.6 mmol, 1.0 equiv.) was dissolved in MeOH (60 mL) and water (12 mL), then KOH (2.2 g, 39.4 mmol, 2.0 equiv.) was added. The reaction mixture was stirred for 3 hours at ambient temperature and concentrated under vacuum. The residue was diluted with water, then adjusted to pH 3 with aqueous HCl (6M). The resulting solids were collected by filtration and dried to give [(5,6-difluoro-1H-indol-3-yl)carbamoyl]formic acid (2.5 g) as a yellow solid. LCMS Method CB: [M−H]=239.


Step 3: N-(5,6-difluoro-1H-indol-3-yl)-N′-[trans-3-[(5-methylpyridin-2-yl)oxy]cyclobutyl]ethanediamide

[(5,6-difluoro-1H-indol-3-yl)carbamoyl]formic acid (200.0 mg, 0.8 mmol, 1.0 equiv.) was dissolved in DCM (20.0 mL), then trans-3-[(5-methylpyridin-2-yl)oxy]cyclobutan-1-amine (148.4 mg, 0.8 mmol, 1.0 equiv.), HATU (474.9 mg, 1.2 mmol, 1.5 equiv.) and DIEA (0.3 mL, 1.7 mmol, 2.0 equiv.) were added. The reaction mixture was stirred for 16 hours at ambient temperature and then quenched by the addition of water. The resulting mixture was extracted with ethyl acetate, washed with brine, dried over anhydrous Na2SO4 and concentrated under vacuum. The residue was purified by Prep-HPLC with the following conditions: Column: XBridge Shield RP18 OBD Column, 30*150 mm, 5 m; Mobile Phase A: Water/10 mM NH4HCO3+0.1% NH4OH, Mobile Phase B: Acetonitrile; Flow rate: 60 mL/min; Gradient: 40 B to 65 B in 7 min; 254 nm. This gave N-(5,6-difluoro-1H-indol-3-yl)-N′-[trans-3-[(5-methylpyridin-2-yl)oxy]cyclobutyl]ethanediamide (154.1 mg) as a white solid. LCMS Method CF: [M+H]+=401. 1H NMR (400 MHz, DMSO-d6) δ 11.17 (s, 1H), 10.67 (s, 1H), 9.35 (d, 1H), 7.96-7.91 (m, 2H), 7.81 (d, 1H), 7.56-7.53 (m, 1H), 7.40-7.36 (m, 1H), 6.74 (d, 1H), 5.30-5.26 (m, 1H), 4.51-4.46 (m, 1H), 2.69-2.61 (m, 2H), 2.42-2.37 (m, 2H), 2.21 (s, 3H).

Biological Assays

STING pathway activation by the compounds described herein was measured using THIP1-Dua1™ cells (KO-IFNAR2).


TTIP1-Dual™ KO-IFNAR2 Cells (obtained from invivogen) were maintained in RPMI, 10% FCS, 5 ml P/S, 2 mM L-glut, 10 mM Hepes, and 1 mM sodium pyruvate. Compounds were spotted in empty 384 well tissue culture plates (Greiner 781182) by Echo for a final concentration of 0.0017-100 μM. Cells were plated into the TC plates at 40 μL per well, 2×10E6 cells/mL. For activation with STING ligand, 2′3′cGAMP (MW 718.38, obtained from Invivogen), was prepared in Optimem media.


The following solutions were prepared for each 1×384 plate:

    • Solution A: 2 mL Optimem with one of the following stimuli:
      • 60 uL of 10 mM 2′3′cGAMP->150 μM stock
    • Solution B: 2 mL Optimem with 60 μL Lipofectamine 2000->Incubate 5 min at RT


2 mL of solution A and 2 ml Solution B was mixed and incubated for 20 min at room temperature (RT). 20 uL of transfection solution (A+B) was added on top of the plated cells, with a final 2′3′cGAMP concentration of 15 μM. The plates were then centrifuged immediately at 340 g for 1 minute, after which they were incubated at 37° C., 5% C02, >98% humidity for 24h. Luciferase reporter activity was then measured. EC50 values were calculated by using standard methods known in the art.


Luciferase reporter assay: 10 μL of supernatant from the assay was transferred to white 384-plate with flat bottom and squared wells. One pouch of QUANTI-Luc™ Plus was dissolved in 25 mL of water. 100 μL of QLC Stabilizer per 25 mL of QUANTI-Luc™ Plus solution was added. 50 μL of QUANTI-Luc™ Plus/QLC solution per well was then added. Luminescence was measured on a Platereader (e.g., Spectramax I3X (Molecular Devices GF3637001)).


Luciferase reporter activity was then measured. EC50 values were calculated by using standard methods known in the art.


Table BA shows the activity of compounds in STING reporter assay: <0.008 μM=“++++++”; >0.008 and <0.04 μM=“+++++”; >0.04 and <0.2 μM=“++++”; >0.2 and <1 μM=“+++” >1 and <5 μM=“++”; >5 and <100 μM=“+”.
