Abstract
Compounds of Formula I or pharmaceutically acceptable salts or esters thereof capable of binding to and modulating the activity of a stimulator of interferon genes (STING) protein are provided. Methods involving compounds of Formula I as effective modulators of STING are also provided.
Description
BACKGROUND

Modulating innate immune activity by agonizing or antagonizing pattern recognition receptors (PRRs) has vast potential for clinical applications both as monotherapy and in combination with other pharmaceutical or bio-pharmaceutical agents. The applications range from alleviating autoimmune disorders through immunosuppression to treating solid and hematological cancers by stimulating innate anti-tumor immunity, as well as uses in anti-viral therapy or as vaccine adjuvant.


One of the PRRs involved in the effective activation of antigen presenting cells (APCs) is the stimulator of interferon genes (STING) protein. STING is an evolutionarily conserved, cytosolic PRR that is part of the cGAS-CDN-STING axis. Aberrant dsDNA in the cytosol, as a consequence of cell stress, viral or intracellular bacterial infection, failed mitosis, or phagocytosis, is recognized by the cGAS enzyme, which synthesizes the non-canonical cyclic di-nucleotide (CDN), 2′3′cGAMP, 2′3′cGAMP binds to and stabilizes the STING dimer, resulting in IRF3 and NFkB activation and synthesis of type I interferon. STING protein plays an important role in innate cellular responses to viral infection and aberrant cytosolic DNA accumulation in both target cells and responding innate immune cells. The pleiotropic effects of STING activation are cell-type and context dependent. For example, overstimulation of T cells and B cells through STING leads to a pro-apoptotic phenotype, while in myeloid cells STING activation elevates type I IFN and pro-inflammatory cytokines without an increase in apoptosis.


Tumor derived dsDNA is phagocytosed by resident dendritic cells (DCs), which stimulates the cGAS-CDN-STING axis and activates DCs, leading to lymph node migration and, ultimately, proliferation of antigen specific CD4+ and CD8+ T cells. This process and the accompanying type I IFN response are often absent in tumors that lack a T cell infiltrate, highlighting the potential of STING agonization to directly address the mechanism of escape exploited by these tumors. Although several CDN derived ligands have shown pre-clinical promise as STING agonists, their relatively large molecular weight and polarity have limited their application to intratumoral injection. Moreover, binding and activation/inhibition of the cytosolic STING protein is limited in vivo by cell membrane permeability. Furthermore, despite their therapeutic efficacy via systemic administration (i.v. or i.p.), the previously identified small molecule STING agonists DMXAA and CMA exhibit species selectivity, prohibiting their use as human therapeutics. Thus, there is a need for human-active small molecule modulators of STING for use as effective therapeutic agents. The present application addresses this need. The novel compounds of this application overcome the limitations of CDN derived ligands.

Some of the foregoing compounds can comprise one or more asymmetric centers, and thus can exist in various isomeric forms. e.g., stereoisomers and/or diastereomers. Accordingly, compounds of the application may be in the form of an individual enantiomer, diastereomer or geometric isomer, or may be in the form of a mixture of stereoisomers. In one embodiment, the compounds of the application are enantiopure compounds. In another embodiment, mixtures of stereoisomers or diastereomers are provided.

Such compounds are useful for drug metabolism studies and diagnostics, as well as therapeutic applications.


Potency can also be determined by IC50 value. A compound with a lower IC50 value, as determined under substantially similar conditions, is more potent relative to a compound with a higher IC50 value. In some embodiments, the substantially similar conditions comprise determining the level of binding of a known STING ligand to a STING protein, in vitro or in vivo, in the presence of a compound of the application.


In one embodiment, the compounds of the present application are useful as therapeutic agents, and thus may be useful in the treatment of a disease caused by, or associated with, STING expression, activity, and/or function (e.g., deregulation of STING expression, activity, and/or function) or a disease associated with one or more of the intracellular pathways that STING is involved in (e.g. regulation of intracellular DNA-mediated type I interferon activation), such as those described herein.


A “selective STING modulator” can be identified, for example, by comparing the ability of a compound to modulate STING expression/activity/function to its ability to modulate the other proteins or a STING protein from another species.

Method of Synthesizing the Compounds


Compounds of the present application can be prepared in a variety of ways using commercially available starting materials, compounds known in the literature, or from readily prepared intermediates, by employing standard synthetic methods and procedures either known to those skilled in the art, or which will be apparent to the skilled artisan in light of the teachings herein. Standard synthetic methods and procedures for the preparation of organic molecules and functional group transformations and manipulations can be obtained from the relevant scientific literature or from standard textbooks in the field. Although not limited to any one or several sources, classic texts such as Smith, M. B., March, J., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 5th edition, John Wiley & Sons: New York, 2001; and Greene, T. W., Wuts, P. G. M., Protective Groups in Organic Synthesis, 3rd edition, John Wiley & Sons: New York, 1999, incorporated by reference herein, are useful and recognized reference textbooks of organic synthesis known to those in the art. The following descriptions of synthetic methods are designed to illustrate, but not to limit, general procedures for the preparation of compounds of the present application. The processes generally provide the desired final compound at or near the end of the overall process, although it may be desirable in certain instances to further convert the compound to a pharmaceutically acceptable salt, ester, or prodrug thereof. Suitable synthetic routes are depicted in the schemes below.


Those skilled in the art will recognize if a stereocenter exists in the compounds disclosed herein. Accordingly, the present application includes both possible stereoisomers (unless specified in the synthesis) and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be affected by any suitable method known in the art. See, for example, “Stereochemistry of Organic Compounds” by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-Interscience, 1994).


The compounds of the present application can be prepared in a number of ways well known to those skilled in the art of organic synthesis. By way of example, compounds of the present application can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include but are not limited to those methods described below.


Compounds of the present application can be synthesized by following the steps outlined in the following Schemes, which comprise different sequences of assembling intermediates. Starting materials are either commercially available or made by known procedures in the reported literature or as illustrated. As shown in the Schemes below, compounds of the present application may be synthesized from transition-metal catalyzed cross coupling reactions with known compounds. The cross-coupling reactions, as illustrated below, can provide the compounds of the present application or intermediates that can be further hydrogenated or deprotected to provide the target compounds.

As shown in Schemes 1a-1d, copper-catalyzed Ullmann-type coupling between the requisite aniline (BI, B2, B3, or B4) and the properly substituted 2-bromobenzoic acid or 2-iodobenzoic acid (A) yields the corresponding diphenylamines (C1, C2, C3, or C4) (1a-1). Alternatively, diphenylamines (C1, C2, C3, or C4) can be prepared according to 1a-2 or 1a′. Cyclodehydration of the diphenylamines (C1, C2, C3, C4) affords substituted 10H-acridin-9-one (D1, D2a, D2b, D3, or D4) (1b). Alkylation of the 10H-acridin-9-one (D1, D2a, D2b, D3, or D4), followed by saponification, generates the target compounds (E1, E2a, E2b, E3, or E4) (1c). Alternatively, hydrogenation of the 10H-acridin-9-one (D1, D2a, D2b, D3, or D4), followed by saponification, generates additional target compounds (F1, F2a, F2b, F3, or F4) (1d).

Additional compounds of the present application can be prepared using the procedures according to Schemes 5-14.


A compound of the application can be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid. Alternatively, a pharmaceutically acceptable base addition salt of a compound of the application can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. The pharmaceutically acceptable salt may include various counterions, e.g., counterions of the inorganic or organic acid, counterions of the inorganic or organic base, or counterions afforded by counterion exchange.


Acids and bases useful in the methods herein are known in the art. Acid catalysts are any acidic chemical, which can be inorganic (e.g., hydrochloric, sulfuric, nitric acids, aluminum trichloride) or organic (e.g., camphorsulfonic acid, p-toluenesulfonic acid, acetic acid, ytterbium triflate) in nature. Acids are useful in either catalytic or stoichiometric amounts to facilitate chemical reactions. Bases are any basic chemical, which can be inorganic (e.g., sodium bicarbonate, potassium hydroxide) or organic (e.g., triethylamine, pyridine) in nature. Bases are useful in either catalytic or stoichiometric amounts to facilitate chemical reactions.


Alternatively, the salt forms of the compounds of the application can be prepared using salts of the starting materials or intermediates. The free acid or free base forms of the compounds of the application can be prepared from the corresponding base addition salt or acid addition salt from, respectively. For example, a compound of the application in an acid addition salt form can be converted to the corresponding free base by treating with a suitable base (e.g., ammonium hydroxide solution, sodium hydroxide, and the like). A compound of the application in a base addition salt form can be converted to the corresponding free acid by treating with a suitable acid (e.g., hydrochloric acid, etc.).


Compounds of the present application that contain nitrogens can be converted to N-oxides by treatment with an oxidizing agent (e.g., 3-chloroperoxybenzoic acid (m-CPBA) and/or hydrogen peroxides) to afford other compounds of the present application. Thus, all shown and claimed nitrogen-containing compounds are considered, when allowed by valency and structure, to include both the compound as shown and its N-oxide derivative (which can be designated as N→O or N+—O−). Furthermore, in other instances, the nitrogens in the compounds of the present application can be converted to N-hydroxy or N-alkoxy compounds. For example, N-hydroxy compounds can be prepared by oxidation of the parent amine by an oxidizing agent such as m-CPBA. All shown and claimed nitrogen-containing compounds are also considered, when allowed by valency and structure, to cover both the compound as shown and its N-hydroxy (i.e., N—OH) and N-alkoxy (i.e., N—OR, wherein R is substituted or unsubstituted C1-C6 alkyl, C1-C6 alkenyl, C1-C6 alkynyl, 3-14-membered carbocycle or 3-14-membered heterocycle) derivatives.


Prodrugs of the compounds of the application can be prepared by methods known to those of ordinary skill in the art (e.g., for further details see Saulnier et al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985). For example, appropriate prodrugs can be prepared by reacting a non-derivatized compound of the application with a suitable carbamylating agent (e.g., 1,1-acyloxyalkylcarbanochloridate, para-nitrophenyl carbonate, or the like). Specifically, the central N-acetic acid moeity, and other analogous carboxylic acid groups, of the compounds of the present invention can be modified through techniques known in the art to produce effective prodrugs of the present invention.


Protected derivatives of the compounds of the application can be made by means known to those of ordinary skill in the art. A detailed description of techniques applicable to the creation of protecting groups and their removal can be found in T. W. Greene, “Protecting Groups in Organic Chemistry”, 3rd edition, John Wiley and Sons, Inc., 1999.


Compounds of the present application can be conveniently prepared, or formed during the process of the application, as solvates (e.g., hydrates). Hydrates of compounds of the present application can be conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents such as dioxin, tetrahydrofuran or methanol.


Optical isomers may be prepared from their respective optically active precursors by the procedures described herein, or by resolving the racemic mixtures. The resolution can be carried out in the presence of a resolving agent, by chromatography or by repeated crystallization or by some combination of these techniques which are known to those skilled in the art. Further details regarding resolutions can be found in Jacques, et al., Enantiomers, Racemates, and Resolutions (John Wiley & Sons, 1981).


The synthesized compounds can be separated from a reaction mixture and further purified by a method such as column chromatography, high pressure liquid chromatography, or recrystallization. As can be appreciated by the skilled artisan, further methods of synthesizing the compounds of the formulae herein will be evident to those of ordinary skill in the art. Additionally, the various synthetic steps may be performed in an alternate sequence or order to give the desired compounds. In addition, the solvents, temperatures, reaction durations, etc. delineated herein are for purposes of illustration only and one of ordinary skill in the art will recognize that variation of the reaction conditions can produce the desired bridged macrocyclic products of the present application. Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing the compounds described herein are known in the art and include, for example, those such as described in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2d. Ed., John Wiley and Sons (1991); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995), and subsequent editions thereof.


The compounds of this application may be modified by appending various functionalities via any synthetic means delineated herein to enhance selective biological properties. Such modifications are known in the art and include those which increase biological penetration into a given biological system (e.g., blood, lymphatic system, central nervous system), increase oral availability, increase solubility to allow administration by injection, alter metabolism and alter rate of excretion.


Biological Assays


Biological activities of the compounds of the present application can be measured by various biochemical or cellular assays known to one of ordinary skill in the art. Non-limiting examples of biochemical and cellular assays are listed herein below.


SWAT Protein FP Competition Dose Response Assay


A validated STING ligand, such as c-di-GMP, which is labeled with a read-out signal (e.g., a fluorescence signal such as fluorescein), is mixed with STING-CTD (e.g., mouse STING-CTD or human STING-CTD) with or without the presence of a compound of the present application. Changes in the read-out signal are measured (e.g., by fluorescence anisotropy) to determine the binding of the compound to STING-CTD.


Pharmaceutical Compositions


In another aspect, a pharmaceutical composition is provided. The pharmaceutical composition comprises a therapeutically effective amount of a compound of the application, or a pharmaceutically acceptable salt or ester thereof, and a pharmaceutically acceptable carrier.


Compounds of the application may be administered as pharmaceutical compositions by any conventional route, in particular enterally. e.g., orally, e.g., in the form of tablets or capsules, or parenterally, e.g., in the form of injectable solutions or suspensions, or topically, e.g., in the form of lotions, gels, ointments or creams, or in a nasal or suppository form.


Pharmaceutical compositions including a compound of the present application in free form or in a pharmaceutically acceptable salt form in association with at least one pharmaceutically acceptable carrier or diluent may be manufactured in a conventional manner by mixing, granulating or coating methods. For example, oral compositions can be tablets or gelatin capsules comprising the active ingredient together with a) diluents. e.g., lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or glycine; b) lubricants, e.g., silica, talcum, stearic acid, its magnesium or calcium salt and/or polyethyleneglycol; for tablets also c) binders, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and or polyvinylpyrrolidone; if desired d) disintegrants, e.g., starches, agar, alginic acid or its sodium salt, or effervescent mixtures; and/or e) absorbents, colorants, flavors and sweeteners. Injectable compositions can be aqueous isotonic solutions or suspensions, and suppositories can be prepared from fatty emulsions or suspensions. The compositions may be sterilized and/or contain adjuvants, such as preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure and/or buffers. In addition, they may also contain other therapeutically valuable substances. Suitable formulations for transdermal applications include an effective amount of a compound of the present application with a carrier. A carrier may include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. For example, transdermal devices may be in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. Matrix transdermal formulations may also be used. Suitable formulations for topical application, e.g., to the skin and eyes, are preferably aqueous solutions, ointments, creams or gels well-known in the art. Such may contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.


The pharmaceutical compositions of the present application comprise a therapeutically effective amount of a compound of the present application formulated together with one or more pharmaceutically acceptable carriers. As used herein, the term “pharmaceutically acceptable carrier” means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which may serve as pharmaceutically acceptable carriers include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, or 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, polyacrylates, waxes, polyethylenepolyoxy propylene-block polymers, wool fat, sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes, oils such as peanut oil, cottonseed oil; safflower oil; sesame oil; olive oil; corn oil and soybean oil; glycols such a propylene glycol or polyethylene glycol; esters such as ethyl oleate and ethyl laurate, agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water, isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.


The pharmaceutical compositions of this application may be administered to humans and other animals orally, rectally, parenterally, intracistemally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), buccally, or as an oral or nasal spray.


Liquid dosage forms for oral administration may include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.


Injectable preparations, for example, sterile injectable aqueous, or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally 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 are used in the preparation of injectables.


In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.


Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this application 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 or vaginal cavity and release the active compound.


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.


The active compounds may also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents.


Dosage forms for topical or transdermal administration of a compound of this application include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, eye ointments, powders and solutions are also contemplated as being within the scope of this application.


The ointments, pastes, creams and gels may contain, in addition to an active compound of this application, excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.


Powders and sprays can contain, in addition to the compounds of this application, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons.


Transdermal patches have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.


For any compound, the therapeutically effective amount can be estimated initially either in cell culture assays, e.g., of neoplastic cells, or in animal models, usually rats, mice, rabbits, dogs, or pigs. The animal model may also be used to determine the appropriate concentration range and route of administration. Such information can then be used to determine useful doses and routes for administration in humans. Therapeutic/prophylactic efficacy and toxicity may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., ED50 (the dose therapeutically effective in 50% of the population) and LD50 (the dose lethal to 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, and it can be expressed as the ratio, LD50/ED50. Pharmaceutical compositions that exhibit large therapeutic indices are preferred. The dosage may vary within this range depending upon the dosage form employed, sensitivity of the patient, and the route of administration.


Dosage and administration are adjusted to provide sufficient levels of the active agent(s) or to maintain the desired effect. Factors which may be taken into account include the severity of the disease state, general health of the subject, age, weight, and gender of the subject, diet, time and frequency of administration, drug combination(s), reaction sensitivities, and tolerance/response to therapy. Long-acting pharmaceutical compositions may be administered every 3 to 4 days, every week, or once every two weeks depending on half-life and clearance rate of the particular formulation.


The quantity of active ingredient (e.g., a formulation of the disclosed compound or salt, hydrate, solvate or isomer thereof) in a unit dose of composition is an effective amount and is varied according to the particular treatment involved. One skilled in the art will appreciate that it is sometimes necessary to make routine variations to the dosage depending on the age and condition of the patient. The dosage will also depend on the route of administration. A variety of routes are contemplated, including oral, pulmonary, rectal, parenteral, transdermal, subcutaneous, intravenous, intramuscular, intraperitoneal, inhalational, buccal, sublingual, intrapleural, intrathecal, intranasal, and the like. Dosage forms for the topical or transdermal administration of a compound of this application include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. In one embodiment, the active compound is mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers or propellants that are required.


The pharmaceutical compositions containing active compounds of the present application may be manufactured in a manner that is generally known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. Pharmaceutical compositions may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers comprising excipients and/or auxiliaries that facilitate processing of the active compounds into preparations that can be used pharmaceutically. Of course, the appropriate formulation is dependent upon the route of administration chosen.


Techniques for formulation and administration of the disclosed compounds of the application can be found in Remington: the Science and Practice of Pharmacy, 19th edition, Mack Publishing Co., Easton, Pa.

As modulators of a STING protein, the compounds and compositions of this application are also useful in assessing, studying, or testing biological samples. One aspect of the application relates to modulating the activity of a STING protein in a biological sample, comprising contacting the biological sample with a compound or a composition of the application.


The term “biological sample”, as used herein, means an in vitro or an ex vivo sample, including, without limitation, cell cultures or extracts thereof; biopsied material obtained from a mammal or extracts thereof; and blood, saliva, urine, feces, semen, tears, or other body fluids or extracts thereof. Modulation (e.g., inhibition or stimulation) of protein kinase activity in a biological sample is useful for a variety of purposes that are known to one of skill in the art. Examples of such purposes include, but are not limited to, blood transfusion, organ transplantation, and biological specimen storage.


Another aspect of this application relates to the study of a STING protein in biological and pathological phenomena; the study of intracellular signal transduction pathways mediated by STING protein. Examples of such uses include, but are not limited to, biological assays such as enzyme assays and cell-based assays.


The activity of the compounds and compositions of the present application as STING modulators may be assayed in vitro, in vivo, or in a cell line. In vitro assays include assays that determine modulation (e.g., inhibition or stimulation) of binding of a STING ligand to a STING protein through competitive binding assay. Alternate in vitro assays quantitate the ability of the modulator (e.g., inhibitor or stimulator) to bind to the protein kinase and may be measured either by radio labelling the modulator (e.g., inhibitor or stimulator) prior to binding, isolating the ligand/protein complex and determining the amount of radio label bound. Detailed conditions for assaying a compound utilized in this application as a modulator or a STING protein are set forth in the Examples below.


In accordance with the foregoing, the present application provides a method for preventing or treating any of the diseases or disorders described herein in a subject in need of such treatment, comprising administering to the subject a therapeutically effective amount of a compound of the application or an enantiomer, diastereomer, stereoisomer, or pharmaceutically acceptable salt thereof, or a pharmaceutical composition of the application. For any of the above uses, the required dosage will vary depending on the mode of administration, the particular condition to be treated and the effect desired.


Compounds and compositions of the application can be administered in therapeutically effective amounts in a combinational therapy with one or more therapeutic agents (pharmaceutical combinations) or modalities, e.g., anti-proliferative, anti-cancer, immunomodulatory (e.g., CTLA-4 and PD-1 pathway antagonists and other immunomodulatory agents), anti-inflammatory, and/or anti-viral agent, and/or non-drug therapies, etc. For example, synergistic effects can occur with anti-proliferative, anti-cancer, immunomodulatory (e.g., CTLA-4 and PD-1 pathway antagonists and other immunomodulatory agents), anti-inflammatory, and/or anti-viral substances. Where the compounds of the application are administered in conjunction with other therapies, dosages of the co-administered compounds will of course vary depending on the type of co-drug employed, on the specific drug employed, on the condition being treated and so forth.


Combination therapy may include the administration of the subject compounds in further combination with one or more other biologically active ingredients (such as, but not limited to, a second STING modulator, a modulator of the cGAS-CDN-STING axis, or a modulator involved in the intracellular dsDNA mediated type-1 interferon activation.

As used herein, “combination therapy” or “co-therapy” includes the administration of a compound of the present application, or a pharmaceutically acceptable salt or ester thereof, and at least a second agent as part of a specific treatment regimen intended to provide the beneficial effect from the co-action of these therapeutic agents. The beneficial effect of the combination includes, but is not limited to, pharmacokinetic or pharmacodynamic co-action resulting from the combination of therapeutic agents. Administration of these therapeutic agents in combination typically is carried out over a defined time period (usually minutes, hours, days or weeks depending upon the combination selected). “Combination therapy” may be, but generally is not, intended to encompass the administration of two or more of these therapeutic agents as part of separate monotherapy regimens that incidentally and arbitrarily result in the combinations of the present application.


“Combination therapy” is intended to embrace administration of these therapeutic agents in a sequential manner, wherein each therapeutic agent is administered at a different time, as well as administration of these therapeutic agents, or at least two of the therapeutic agents, in a substantially simultaneous manner. Substantially simultaneous administration can be accomplished, for example, by administering to the subject a single capsule having a fixed ratio of each therapeutic agent or in multiple, single capsules for each of the therapeutic agents. Sequential or substantially simultaneous administration of each therapeutic agent can be effected by any appropriate route including, but not limited to, oral routes, intravenous routes, intramuscular routes, and direct absorption through mucous membrane tissues. The therapeutic agents can be administered by the same route or by different routes. For example, a first therapeutic agent of the combination selected may be administered by intravenous injection while the other therapeutic agents of the combination may be administered orally. Alternatively, for example, all therapeutic agents may be administered orally or all therapeutic agents may be administered by intravenous injection. The sequence in which the therapeutic agents are administered is not narrowly critical.


“Combination therapy” also embraces the administration of the therapeutic agents as described herein in further combination with other biologically active ingredients and non-drug therapies (e.g., surgery or radiation treatment). Where the combination therapy further comprises a non-drug treatment, the non-drug treatment may be conducted at any suitable time so long as a beneficial effect from the co-action of the combination of the therapeutic agents and non-drug treatment is achieved. For example, in appropriate cases, the beneficial effect is still achieved when the non-drug treatment is temporally removed from the administration of the therapeutic agents, perhaps by days or even weeks.


As used herein, the term “immune response” relates to any one or more of the following: specific immune response, non-specific immune response, both specific and nonspecific response, innate response, primary immune response, adaptive immunity, secondary immune response, memory immune response, immune cell activation, immune cell proliferation, immune cell differentiation, and cytokine expression.

Thus, the term “cancerous cell” as provided herein, includes a cell afflicted by any one of the above-identified conditions.


The term “subject” as used herein refers to a mammal. A subject therefore refers to, for example, dogs, cats, horses, cows, pigs, guinea pigs, and the like. Preferably the subject is a human. When the subject is a human, the subject may be referred to herein as a patient.


“Treat”, “treating” and “treatment” refer to a method of alleviating or abating a disease and/or its attendant symptoms.


As used herein, “preventing” or “prevent” describes reducing or eliminating the onset of the symptoms or complications of the disease, condition or disorder.


The terms “disease(s)”, “disorder(s)”, and “condition(s)” are used interchangeably, unless the context clearly dictates otherwise.


The term “therapeutically effective amount” of a compound or pharmaceutical composition of the application, as used herein, means a sufficient amount of the compound or pharmaceutical composition so as to decrease the symptoms of a disorder in a subject. As is well understood in the medical arts a therapeutically effective amount of a compound or pharmaceutical composition of this application will be at a reasonable benefit/risk ratio applicable to any medical treatment. It will be understood, however, that the total daily usage of the compounds and compositions of the present application will be decided by the attending physician within the scope of sound medical judgment. The specific modulatory (e.g., inhibitory or stimulatory) dose for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well known in the medical arts.


As used herein, the phrase “pharmaceutically acceptable” refers to those compounds, materials, compositions, carriers, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.


As used herein, the term “pharmaceutically acceptable salt” refers to those salts of the compounds formed by the process of the present application which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge, et al. describes pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 66: 1-19 (1977). The salts can be prepared in situ during the final isolation and purification of the compounds of the application, or separately by reacting the free base or acid function with a suitable acid or base.


Examples of pharmaceutically acceptable salts include, but are not limited to, nontoxic acid addition salts: salts formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid, or with organic acids such as acetic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid. Other pharmaceutically acceptable salts include, but are not limited to, adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, 7-toluenesulfonate, undecanoate, valerate salts, and the like. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, alkyl having from 1 to 6 carbon atoms, sulfonate and aryl sulfonate.


As used herein, the term “pharmaceutically acceptable ester” refers to esters of the compounds formed by the process of the present application which hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Examples of particular esters include, but are not limited to, formates, acetates, propionates, butyrates, acrylates and ethylsuccinates.


The term “pharmaceutically acceptable prodrugs” as used herein, refers to those prodrugs of the compounds formed by the process of the present application which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals with undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of the present application.


“Prodrug”, as used herein, means a compound which is convertible in vivo by metabolic means (e.g., by hydrolysis) to afford any compound delineated by the formulae of the instant application. Various forms of prodrugs are known in the art, for example, as discussed in Bundgaard, (ed.), Design of Prodrugs, Elsevier (1985); Widder, et al. (ed.), Methods in Enzymology, vol. 4, Academic Press (1985); Krogsgaard-Larsen, et al., (ed). “Design and Application of Prodrugs, Textbook of Drug Design and Development, Chapter 5, 113-191 (1991); Bundgaard, et al., Journal of Drug Deliver Reviews, 8:1-38(1992); Bundgaard, J. of Pharmaceutical Sciences, 77:285 et seq. (1988); Higuchi and Stella (eds.) Prodrugs as Novel Drug Delivery Systems, American Chemical Society (1975); and Bernard Testa & Joachim Mayer, “Hydrolysis In Drug And Prodrug Metabolism: Chemistry, Biochemistry And Enzymology.” John Wiley and Sons, Ltd. (2002).


“Pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes excipient that is acceptable for veterinary use as well as human pharmaceutical use. A “pharmaceutically acceptable excipient” as used in the specification and claims includes both one and more than one such excipient.


This application also encompasses pharmaceutical compositions containing, and methods of treating disorders through administering, pharmaceutically acceptable prodrugs of compounds of the application. For example, compounds of the application having free amino, amido, hydroxy or carboxylic groups can be converted into prodrugs. Prodrugs include compounds wherein an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues is covalently joined through an amide or ester bond to a free amino, hydroxy or carboxylic acid group of compounds of the application. The amino acid residues include but are not limited to the 20 naturally occurring amino acids commonly designated by three letter symbols and also includes 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline, homocysteine, homoserine, ornithine and methionine sulfone. Additional types of prodrugs are also encompassed. For instance, free carboxyl groups can be derivatized as amides or alkyl esters. Free hydroxy groups may be derivatized using groups including but not limited to hemisuccinates, phosphate esters, dimethylaminoacetates, and phosphoryloxymethyloxy carbonyls, as outlined in Advanced Drug Delivery Reviews. 1996, 19, 1-15. Carbamate prodrugs of hydroxy and amino groups are also included, as are carbonate prodrugs, sulfonate esters and sulfate esters of hydroxy groups. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers wherein the acyl group may be an alkyl ester, optionally substituted with groups including but not limited to ether, amine and carboxylic acid functionalities, or where the acyl group is an amino acid ester as described herein, are also encompassed. Prodrugs of this type are described in J. Med. Chem. 1996, 39, 10. Free amines can also be derivatized as amides, sulfonamides or phosphonamides. All of these prodrug moieties may incorporate groups including but not limited to ether, amine and carboxylic acid functionalities.


Combinations of substituents and variables envisioned by this application are only those that result in the formation of stable compounds. The term “stable”, as used herein, refers to compounds which possess stability sufficient to allow manufacture and which maintains the integrity of the compound for a sufficient period of time to be useful for the purposes detailed herein (e.g., therapeutic or prophylactic administration to a subject).


When any variable (e.g., R1) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with one or more R moieties, then R at each occurrence is selected independently from the definition of R. Also, combinations of substituents and/or variables are permissible, but only if such combinations result in stable compounds within a designated atom's normal valency.


In addition, some of the compounds of this application have one or more double bonds, or one or more asymmetric centers. Such compounds can occur as racemates, racemic mixtures, single enantiomers, individual diastereomers, diastereomeric mixtures, and cis- or trans- or E- or Z-double isomeric forms, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)-, or as (D)- or (L)- for amino acids. 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. The configuration of any carbon-carbon double bond appearing herein is selected for convenience only and is not intended to designate a particular configuration unless the text so states; thus a carbon-carbon double bond depicted arbitrarily herein as trans may be cis, trans, or a mixture of the two in any proportion. All such isomeric forms of such compounds are expressly included in the present application.


“Isomerism” means compounds that have identical molecular formulae but differ in the sequence of bonding of their atoms or in the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. Stereoisomers that are not mirror images of one another are termed “diastereoisomers”, and stereoisomers that are non-superimposable mirror images of each other are termed “enantiomers” or sometimes optical isomers. A mixture containing equal amounts of individual enantiomeric forms of opposite chirality is termed a “racemic mixture”.


A carbon atom bonded to four non-identical substituents is termed a “chiral center”.


“Chiral isomer” means a compound with at least one chiral center. Compounds with more than one chiral center may exist either as an individual diastereomer or as a mixture of diastereomers, termed “diastereomeric mixture”. When one chiral center is present, a stereoisomer may be characterized by the absolute configuration (R or S) of that chiral center, e.g., carbon. Absolute configuration refers to the arrangement in space of the substituents attached to the chiral center. The substituents attached to the chiral center under consideration are ranked in accordance with the Sequence Rule of Cahn, Ingold and Prelog. (Cahn et al., Angew. Chem. Inter. Edit. 1966, 5, 385: errata 511; Cahn et al., Angew. Chem. 1966, 78, 413; Cahn and Ingold, J Chem. Soc. 1951 (London), 612; Cahn et al., Experientia 1956, 12, 81: Cahn, J. Chem. Educ. 1964, 41, 116).


“Geometric isomer” means the diastereomers that owe their existence to hindered rotation about double bonds. These configurations are differentiated in their names by the prefixes cis and trans, or Z and E, which indicate that the groups are on the same or opposite side of the double bond in the molecule according to the Cahn-Ingold-Prelog rules.


Furthermore, the structures and other compounds discussed in this application include all atropic isomers thereof. “Atropic isomers” are a type of stereoisomer in which the atoms of two isomers are arranged differently in space. Atropic isomers owe their existence to a restricted rotation caused by hindrance of rotation of large groups about a central bond. Such atropic isomers typically exist as a mixture, however as a result of recent advances in chromatography techniques: it has been possible to separate mixtures of two atropic isomers in select cases.


“Tautomer” is one of two or more structural isomers that exist in equilibrium and is readily converted from one isomeric form to another. This conversion results in the formal migration of a hydrogen atom accompanied by a switch of adjacent conjugated double bonds. Tautomers exist as a mixture of a tautomeric set in solution. In solid form, usually one tautomer predominates. In solutions where tautomerization is possible, a chemical equilibrium of the tautomers will be reached. The exact ratio of the tautomers depends on several factors, including temperature, solvent and pH. The concept of tautomers that are interconvertable by tautomerizations is called tautomerism.


Of the various types of tautomerism that are possible, two are commonly observed. In keto-enol tautomerism a simultaneous shift of electrons and a hydrogen atom occurs. Ring-chain tautomerism arises as a result of the aldehyde group (—CHO) in a sugar chain molecule reacting with one of the hydroxy groups (—OH) in the same molecule to give it a cyclic (ring-shaped) form as exhibited by glucose. Common tautomeric pairs are: ketone-enol, amide-nitrile, lactam-lactim, amide-imidic acid tautomerism in heterocyclic rings (e.g., in nucleobases such as guanine, thymine and cytosine), amine-enamine and enamine-enamine. The compounds of this application may also be represented in multiple tautomeric forms, in such instances, the application expressly includes all tautomeric forms of the compounds described herein (e.g., alkylation of a ring system may result in alkylation at multiple sites, the application expressly includes all such reaction products).


In the present application, the structural formula of the compound represents a certain isomer for convenience in some cases, but the present application includes all isomers, such as geometrical isomers, optical isomers based on an asymmetrical carbon, stereoisomers, tautomers, and the like. In the present specification, the structural formula of the compound represents a certain isomer for convenience in some cases, but the present application includes all isomers, such as geometrical isomers, optical isomers based on an asymmetrical carbon, stereoisomers, tautomers, and the like.


Additionally, the compounds of the present application, for example, the salts of the compounds, can exist in either hydrated or unhydrated (the anhydrous) form or as solvates with other solvent molecules. Non-limiting examples of hydrates include monohydrates, dihydrates, etc. Non-limiting examples of solvates include ethanol solvates, acetone solvates, etc.


“Solvate” means solvent addition forms that contain either stoichiometric or non stoichiometric amounts of solvent. Some compounds have a tendency to trap a fixed molar ratio of solvent molecules in the crystalline solid state, thus forming a solvate. If the solvent is water the solvate formed is a hydrate; and if the solvent is alcohol, the solvate formed is an alcoholate. Hydrates are formed by the combination of one or more molecules of water with one molecule of the substance in which the water retains its molecular state as H2O.

Example 1: Synthesis of Compounds 1-20 and 29-38

Compounds 1-20 and 29-38 were prepared according to Schemes 1a-1c. The first step was a copper-catalyzed Ullmann-type coupling between the requisite aniline and the properly substituted 2-bromobenzoic acid or 2-iodobenzoic acid to form the corresponding diphenylamine. Representative reaction conditions include either Cu2O (0.05 eq), Cu (0.1 eq), and K2CO3 (1.2 eq), refluxed in DMF overnight. Variations in base, solvent, and copper source could be employed.


The second step was a cyclodehydration in H2SO4: H2O (10:1) at elevated temperature (80° C. or higher, overnight) to afford the substituted 10H-acridin-9-one. Other strongly acidic reagents, for example, polyphosphoric acid, were also effective for this purpose. In cases where the diphenylamine was synthesized from a starting aniline that did not possess an ortho-substituent, a mixture of regioisomers was obtained from the cyclodehydration. This mixture could be separated using normal phase silica gel chromatography.


Alkylation of the 10H-acridin-9-one was accomplished with ethyl bromoacetate and an excess of Cs2CO3 with heating in DMF (80° C., 2 hr). The ester of the bromoacetate, the base, and the solvent utilized in this step could be modified as needed. If the alkylation during produced a putative mixture of N- and O-alkylated products, the ratio depended on the 10H-acridin-9-one substituents. These products were saponified as a mixture using metal hydroxide (NaOH, LiOH, or KOH) in a protic solvent, such as methanol or a THF/water mixture. Purification by extraction or reverse phase prep-HPLC delivered the desired substituted 10-carboxymethyl-9-acridinone.


Example 2: Synthesis of Compound 13
Step 1: Synthesis of N-(2,3-dichloro-phenyl)-anthranilic acid

2-bromobenzoic acid (4.0 g, 19.9 mmol, 1 eq), 2,3-dichloroaniline (3.55 g, 21.9 mmol, 1.1 eq), Cu2O (849 mg, 5.9 mmol, 0.3 eq), Cu (384 mg, 5.9 mmol, 0.3 eq), and K2CO3 (5.8 g, 41.3 mmol, 2.05 eq) were combined in DMF and heated to 140° C. for 4 hrs. The mixture was cooled to room temperature, pour onto ice-water, acidified with 2M aqueous HCl, and extracted with ethyl acetate (25 mL×5). The combined organic layers were washed with brine and concentrated to give the crude product which was triturated petroleum ether to give 2.9 g of the desired material as a solid.

HPE





Each Assay Plate contained HPE/ZPE, and 12 test compounds.


HPE well was 335 nL DMSO + 50 nL assay buffer containing 6 uM probe + 10 uL assay buffer.


ZPE well was 335 nL DMSO + 50 nL assay buffer containing 6 uM probe + 10 uL assay buffer containing 10 uM hSTING protein.


Test compound well was 335 nL DMSO containing compound (highest concentration at 1000 uM, and 14 decreasing concentrations through 2-fold serial dilution) + 50 nL assay buffer containing 6 uM probe + 10 uL assay buffer containing 10 uM hSTING protein.


For each assay, two reference compounds, DMXAA and 2′3′-cGAMP, were included in the last Assay Plate.


DMXAA well was 335 nL DMSO containing DMXAA (highest concentration at 8.95 mM, and 14 decreasing concentrations through 2-fold serial dilution) + 50 nL assay buffer containing 6 uM probe + 10 nL assay buffer containing 10 uM hSTING protein.


2′3′-cGAMP well was 335 nL DMSO containing 2′3′-cGAMP (highest concentration at 2.23 mM, and 14 decreasing concentrations through 2-fold serial dilution) + 50 nL assay buffer containing 6 uM probe + 10 uL assay buffer containing 10 uM hSTING protein.







Plate Reading


The EnVision plate reader was used to record the FA value of each well immediately after mixing the reagents or after a few hours without change of signals.


Data Analysis


The raw data and calculated data (Fluorescence anisotropy (FA)) was exported from the EnVision reader. Fluorescence anisotropy (FA)=1000*(S−G*P)/(S+G*2*P), where S=<detector 2 or STING FP(1) channel 2>, P=<detector 1 or STING FP(1) channel 1>, G=G-factor. The FA value of each dose concentration was first normalized as a percentage of inhibition compared with ZPE (DMSO alone) and HPE (2′3′cGAMP+DMSO) controls, which provided a range of 0-100% inhibition. The data points were then plotted using non-linear regression modelling (4 Parameter Logistic Model, Sigmoidal Dose-Response Model) and least sum of squares. The resulting model was used to calculate an IC50 value for the compound.


Example 61: Mouse STING Protein FP Competition Concentration Response Assay

Fluorescein labeled c-di-GMP was mixed with mSTING-CTD with or without the presence of a compound of the present application in PBS in black 384-well plates (10 μL per well). The fluorescence anisotropy was determined on a PerkinElmer EnVisions multi-mode plate reader. The plate can be read immediately after mixing the reagents or after a few hours without change of signals.

Example 62: Radiometric Filtration Binding Competition Assay

A radiometric filtration binding competition assay was performed to quantify the binding affinity of compounds of the present application for the human or mouse STING protein, or associated HAQ human isoform. The competition format filtration binding assay detects the ability of small molecule compounds from binding to and inhibiting the subsequent binding of a tritiated [H3]2′3′cGAMP high affinity STING ligand. The resulting dose response was fit by non-linear regression to determine an IC50 value, from which a Ki value for each compound was extrapolated.


Briefly, the recombinant C-terminal ligand binding domain of the human STING protein (140-379) or mouse STING protein (139-328) [0.5 μM] was incubated in the presence of a compound of the present application (8 point, 2 fold dilution starting at 300 μM) for 30 min or under control conditions. H3 labeled 2′3′cGAMP [25 nM] was then added and allowed to reach binding equilibrium (1 hour). The resulting complexes were then filtered, dried, and scintillation fluid was added and the remaining radio signal was measured to determine the degree of compound ligand inhibition. This assay format was optimized for both the WT and HAQ isoforms of the human protein and the mouse orthologue protein.

Example 63: STING Differential Scanning Fluorimetry (DSF) Assay

A STING DSF assay was performed to determine protein thermostability shift in response to small molecule ligand binding. A STING thermostability shift assay based on differential scanning fluorimetry was used to measure (1) the net shift in melting temperature (ΔTm)between the apo and ligand-bound states of the STING protein and (2) the concentration of the thermal denaturation transition (EC50) as a surrogate measure of binding affinity (K). Briefly, recombinant mouse or human STING protein (aa140-379) comprising the C-terminal binding domain (R232-WT or HAQ isoforms) were purified by affinity chromatography and further processed to remove the purification tag, followed by gel filtration to achieve purity >95%. Protein in assay buffer was transferred to a 384 well plate and incubated with the hydrophobic fluorescent dye SYBR Orange. A temperature ramp was applied to the plate and the resulting dye fluorescence was plotted as a function of temperature. The first derivative of this function (dF/dT) was then used to extrapolate the melting temperature of the protein at various concentrations of compound and determine the thermal denaturation profile of a protein/compound complex.

Example 64: Cell Based Reporter Assays of IRF or IFN-Beta Activation

Cell reporter assays were developed to measure the ability of compounds of the application to agonize the STING protein and activate both IRF/IFN and the NFkB signaling pathways in the myeloid derived cell line THP-1, which is commercially available from several suppliers. Briefly, THP-1 monocytes were transfected and selected for stable integration of 2 reporter constructs. Clones incorporating stably integrated vectors were further selected by antibiotic resistance to blastocidin and zeocin. The reporter constructs included: (1) firefly luciferase reporter gene under the control of an ISG54 promoter fused to five interferon (IFN)-stimulated response elements to measure IRF transcription factor binding activity and (2) secreted embryonic alkaline phosphatase reporter gene under transcription control of an IFN-beta minimal promoter fused to 5 copies of the NFkB consensus transcriptional response element and 3 copies of the c-Rel binding site.


The resulting THP-1 cell line was further modified to incorporate 3 amino acid point mutations (H71R A230G Q293R). This modification of the native TMEM173 gene in THP-1 cells (HAQ) was designed to produce a cell reporter that expressed the most common allelic variant in the human population (THP-1 R232, available from InvivoGen). Alternatively, the TMEM173 gene was knocked out to provide a congenic control to counter-screen for compound activation that was independent of the STING protein (THP-1 STING KO).


Once cell lines were established, reporter assay protocols were developed and optimized to screen small molecule compounds for agonist activity. Assay optimization for efficacy and Z′ value included titration of the following parameters:
