[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Korean Patent Application No. 10-2022-0147897, filed on November 8, 2022, which is incorporated herein by reference in its entirety. [Background technology]
[0002] Stimulator of interferon genes (STING) is a small protein that has recently attracted attention as a target for cancer therapy. STING is an adaptor protein in the cGAS (cyclic GMP-AMP synthase)-STING pathway, a sensing pathway that induces the activation of type I IFN and other inflammatory cytokines, eliciting antiviral and antitumor immune responses (Chen, Q. et al. Regulation and function of the cGAS-STING pathway of cytosolic DNA sensing. Nat. Immunol. 2016, 17, 1142-1149; Woo, SR et al. STING-dependent cytosolic DNA sensing mediates innate immune recognition of immunogenic tumors. Immunity 2014, 41, 830-842). Furthermore, STING activates signal transducer and activator of transcription 6 (STAT6) and the transcription factor interferon regulatory factor 3 (IRF3) through TANK-binding kinase 1 (TBK1) in antiviral and innate immune responses (Burdette DL, Vance RE, STING and the innate immune response to nucleic acids in the cytosol, 2013, Nature Immunology. 14 (1): 19-26). STING agonists can also induce cytokine expression and trigger T cell-mediated innate immune responses, which inhibit cancer cell growth. However, systemic delivery of STING agonists can cause widespread inflammation.
[0003] Various STING agonists are being tested in preclinical and clinical settings. Various agonists in the form of CDN (cyclic dinucleotide) compounds (e.g., ADU-S100, BI-STING, GSK532, JNJ-4412, SB11285, MK-1454, TAK676), bacterial vectors (e.g., SYNB1891, STACT-TREX-1), acyclic dinucleotide (CDN) compounds (e.g., ALG-031048, JNJ-6196, MK-2118, MSA-1, MSA-2, CRD-5500), nanovaccines (e.g., PC7A NP, cGAMP-NP), and ADCs (e.g., XMT-2056, TAK500) are under development using various strategies.
[0004] The most widely used preclinical compound, DMXAA (a vascular disrupting agent), was used clinically in combination with paclitaxel and carboplatin, but its lack of efficacy was confirmed in Phase 3. Furthermore, ADU-S100, the first STING agonist used clinically, was discontinued in 2020.
[0005] Examples of STING agonists are disclosed, for example, in WO2021 / 014365 (macrocyclic compounds as STING agonists), and US2021 / 0139473 (heterocyclic amide-containing compounds as protein modulators), US 2022 / 0073509 (heterocyclic compounds as STING activators), and KR 2022-0024467 (heterocycle-containing STING agonists), each of which is incorporated by reference herein in its entirety. Summary of the Invention [Problem to be solved by the invention]
[0006] However, existing STING agonists appear to exhibit limited bioavailability and require local administration to tumors or be used in combination with other compounds due to overactivation of cytokine expression. Thus, there remains a need for the development of therapeutically effective STING agonists. [Means for solving the problem]

[0194] Pharmaceutical Composition The compositions and methods of the present disclosure can be used to treat individuals in need thereof. In certain embodiments, the individual is a mammal, such as a human, or a non-human mammal. When administered to an animal, such as a human, the composition or compound is preferably administered as a pharmaceutical composition, e.g., comprising a compound of the present disclosure and a pharmaceutically acceptable carrier. Pharmaceutically acceptable carriers are well known in the art and include, for example, aqueous solutions, e.g., water or physiologically buffered saline, or other solvents or vehicles, e.g., glycols, glycerol, oils, e.g., olive oil, or injectable organic esters. In preferred embodiments, when such pharmaceutical compositions are intended for human administration, particularly for invasive administration routes (i.e., routes that avoid transport or diffusion through epithelial barriers, e.g., injection or implantation), the aqueous solutions are pyrogen-free or substantially pyrogen-free. Excipients can be selected, for example, to provide delayed release of the drug or to selectively target one or more cells, tissues, or organs. The pharmaceutical compositions may be in unit dosage form, such as tablets, capsules (including sprinkle capsules and gelatin capsules), granules, lyophilizates for reconstitution, powders, solutions, syrups, suppositories, injections, etc. The compositions may also be present in transdermal delivery systems, such as skin patches. The compositions may also be present in solutions suitable for topical administration, such as lotions, creams, or ointments.
[0195] Pharmaceutically acceptable carriers may contain physiologically acceptable agents that act, for example, to stabilize, increase the solubility, or increase the absorption of compounds such as the compounds of the present disclosure. Such physiologically acceptable agents include, for example, carbohydrates such as glucose, sucrose, or dextran; antioxidants such as ascorbic acid or glutathione; chelating agents; low-molecular-weight proteins; or other stabilizers or excipients. The choice of a pharmaceutically acceptable carrier containing a physiologically acceptable agent depends, for example, on the route of administration of the composition. The preparation or pharmaceutical composition may be a self-emulsifying or self-microemulsifying drug delivery system. The pharmaceutical composition (preparation) may also be a liposome or other polymer matrix, which may, for example, incorporate a compound of the present disclosure therein. For example, liposomes containing phospholipids or other lipids are non-toxic, physiologically acceptable, and metabolizable carriers that are relatively simple to prepare and administer.
[0196] The phrase "pharmaceutically acceptable" is used herein to refer to compounds, materials, compositions, and / or dosage forms that 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.
[0197] The phrase "pharmaceutically acceptable carrier," as used herein, means a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, excipient, solvent, or encapsulating material. Each carrier must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not harmful to the patient. Some examples of materials that can serve as pharmaceutically acceptable carriers include: (1) sugars, such as lactose, glucose, and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose and its derivatives, such as sodium carboxymethylcellulose, ethylcellulose, and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository wax; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil, and soybean oil; (10) glycols, such as propylene glycol, (11) polyols, such as glycerin, sorbitol, mannitol, and polyethylene glycol, (12) esters, such as ethyl oleate and ethyl laurate, (13) agar, (14) buffers, such as magnesium hydroxide and aluminum hydroxide, (15) alginic acid, (16) pyrogen-free water, (17) isotonic saline, (18) Ringer's solution, (19) ethyl alcohol, (20) phosphate buffer solution, and (21) other non-toxic, compatible substances used in pharmaceutical formulations.
[0198] The pharmaceutical compositions (preparations) can be administered to a subject by any of several routes of administration, including, for example, orally (e.g., as a drench, such as in an aqueous or non-aqueous solution or suspension, a tablet, a capsule (including sprinkle capsules and gelatin capsules), a bolus, a powder, a granule, a paste for application to the tongue), absorption through the oral mucosa (e.g., sublingually), subcutaneously, transdermally (e.g., as a patch applied to the skin), and topically (e.g., as a cream, ointment, or spray applied to the skin). The compounds may also be formulated for inhalation. In certain embodiments, the compounds may simply be dissolved or suspended in sterile water. Details of suitable routes of administration and compositions suitable therefor can be found, for example, in U.S. Pat. Nos. 6,110,973, 5,763,493, 5,731,000, 5,541,231, 5,427,798, 5,358,970, and 4,172,896, and the patents cited therein.
[0199] The formulations can be conveniently presented in unit dosage form and can be prepared by any method well known in the art of pharmacy. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will vary depending on the host being treated and the particular mode of administration. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will generally be that amount of compound that produces a therapeutic effect. Generally, out of 100 percent, this amount will range from about 1 percent to about 99 percent of the active ingredient, preferably from about 5 percent to about 70 percent, and most preferably from about 10 percent to about 30 percent.
[0200] Methods of preparing these formulations or compositions include the step of admixing an active compound, such as a compound of the present disclosure, with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately admixing a compound of the present disclosure with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.
[0201] Formulations of the present disclosure suitable for oral administration may be in the form of capsules (including sprinkle capsules and gelatin capsules), cachets, pills, tablets, lozenges (with a flavored base, usually sucrose and acacia or tragacanth), lyophilisates, powders, granules, or as a solution or suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as a pastille (with an inert base, such as gelatin and glycerin, or sucrose and acacia), and / or as a mouthwash, etc., each containing a predetermined amount of a compound of the present disclosure as an active ingredient. The composition or compound may also be administered as a bolus, electuary, or paste.
[0202] To prepare solid dosage forms for oral administration (such as capsules (including sprinkle capsules and gelatin capsules), tablets, pills, dragees, powders, granules, etc.), the active ingredient is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and / or any of the following: (1) fillers or extenders, such as starch, lactose, sucrose, glucose, mannitol, and / or silicic acid; (2) binders, such as carboxymethylcellulose, alginate, gelatin, polyvinylpyrrolidone, sucrose, and / or acacia; (3) humectants, such as glycerol; (4) disintegrants, such as PEG-1000; For example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (5) solution retarders such as paraffin, (6) absorption accelerators such as quaternary ammonium compounds, (7) wetting agents such as cetyl alcohol and glycerol monostearate, (8) absorbents such as kaolin and bentonite clay, (9) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycol, sodium lauryl sulfate, and mixtures thereof, (10) complexing agents such as modified and unmodified cyclodextrins, and (11) coloring agents. For capsules (including sprinkle capsules and gelatin capsules), tablets, and pills, the pharmaceutical compositions may also contain buffering agents. Solid compositions of a similar type may also be used as fillers in soft and hard-filled gelatin capsules using excipients such as lactose or milk sugar and high molecular weight polyethylene glycols.
[0203] Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binders (e.g., gelatin or hydroxypropylmethylcellulose), lubricants, inert diluents, preservatives, disintegrants (e.g., sodium starch glycolate or cross-linked sodium carboxymethylcellulose), surfactants, or dispersing agents. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.
[0204] Tablets and other solid dosage forms of pharmaceutical compositions, such as dragees, capsules (including sprinkle capsules and gelatin capsules), pills, and granules, can be optionally scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical formulation art. They can also be formulated to provide sustained or controlled release of the active ingredient therein, for example, using various ratios of hydroxypropylmethylcellulose, other polymer matrices, liposomes, and / or microspheres to provide the desired release profile. They can be sterilized, for example, by filtration through a bacteria-retaining filter, or by incorporating a sterilizing agent in the form of a sterile solid composition that can be dissolved in sterile water, or some other sterile injectable medium, immediately before use. These compositions can also optionally contain opacifying agents and can be compositions that release the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients.
[0205] Liquid dosage forms useful for oral administration include pharmaceutically acceptable emulsions, lyophilized products for reconstitution, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active ingredient, the liquid dosage form may contain an inert diluent commonly used in the art, such as water or other solvents, cyclodextrin and its derivatives, solubilizers and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (especially cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil, and sesame oil), glycerol, tetrahydrofuryl alcohol, polyethylene glycol, and fatty acid esters of sorbitan, and mixtures thereof.
[0206] Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.
[0207] Suspensions may contain, in addition to the active compound, suspending agents such as ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof.
[0208] Dosage forms for topical or transdermal administration include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches, and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants which may be required.
[0209] The ointments, pastes, creams and gels may contain, in addition to the active compound, excipients such as animal and vegetable fats, oils, waxes, paraffin, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonite, silicic acid, talc and zinc oxide, or mixtures thereof.
[0210] Powders and sprays may contain, in addition to the active compound, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicate and polyamide powder, or mixtures of these substances. Sprays may additionally contain customary propellants, such as chlorofluorohydrocarbons, and volatile unsubstituted hydrocarbons, such as butane and propane.
[0211] Transdermal patches have the additional advantage of providing controlled delivery of the compounds of the present disclosure to the body. Such dosage forms can be prepared by dissolving or dispersing the active compound in a suitable medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate of such flux can be controlled by providing a rate-controlling membrane or by dispersing the compound in a polymer matrix or gel.
[0212] The phrases "parenteral administration" and "administered parenterally," as used herein, refer to modes of administration other than enteral and topical administration, usually by injection, and include, but are not limited to, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, intrathecal, intraspinal, and intrasternal injection and infusion. Pharmaceutical compositions suitable for parenteral administration contain one or more active compounds in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions, or sterile powders that can be reconstituted into sterile injectable solutions or dispersions immediately before use, which may contain antioxidants, buffers, bacteriostats, solutes that render the formulation isotonic with the blood of the intended recipient, or suspending or thickening agents.
[0213] Examples of suitable aqueous and non-aqueous carriers that can be used in the pharmaceutical compositions of the present disclosure include water, ethanol, polyols (e.g., glycerol, propylene glycol, polyethylene glycol, etc.), and suitable mixtures thereof, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by maintaining the required particle size in the case of dispersions, and by the use of surfactants.
[0214] These compositions may also contain auxiliary agents, such as preservatives, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, etc. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, etc. in the compositions. Furthermore, prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents that delay absorption, for example, aluminum monostearate and gelatin.
[0215] In some cases, in order to prolong the effect of a drug, it is desirable to delay the absorption of the drug from subcutaneous or intramuscular injection.This can be achieved by using a liquid suspension of crystalline or amorphous material with poor water solubility.In this case, the absorption rate of the drug depends on its dissolution rate, which in turn may depend on crystal size and crystalline form.Alternatively, delayed absorption of a parenterally administered drug form can be achieved by dissolving or suspending the drug in an oil vehicle.
[0216] Injectable depot forms are prepared by forming microencapsulated matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide. The rate of drug release can be controlled depending on the ratio of drug to polymer and the nature of the particular polymer used. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations can also be prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues.
[0217] For use in the methods of the present disclosure, the active compound can be provided per se, or can be provided in combination with a pharmaceutically acceptable carrier as a pharmaceutical composition containing, for example, 0.1 to 99.5% (more preferably, 0.5 to 90%) of the active ingredient.
[0218] Methods of introduction can also be provided by rechargeable or biodegradable devices. A variety of sustained-release polymeric devices have been developed and tested in vivo in recent years for the controlled delivery of drugs, including proteinaceous biopharmaceuticals. A variety of biocompatible polymers (including hydrogels), including both biodegradable and non-degradable polymers, can be used to form implants for the sustained release of compounds at specific target sites.
[0219] Actual dosage levels of the active ingredient in the pharmaceutical compositions may be varied to obtain an amount of the active ingredient that is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration without being toxic to the patient.
[0220] The selected dosage level will depend on a variety of factors, including the activity of the particular compound or combination of compounds, or esters, salts, or amides thereof, used, the route of administration, the time of administration, the rate of excretion of the particular compound(s) used, the duration of treatment, other drugs, compounds, and / or materials used in combination with the particular compound(s) used, the age, sex, weight, condition, general health, and past medical history of the patient being treated, and similar factors well known in the medical arts.
[0221] A physician or veterinarian of ordinary skill in the art can easily determine and prescribe the therapeutically effective amount of the pharmaceutical composition required. For example, a physician or veterinarian can start a dose of the pharmaceutical composition or compound at a level lower than that required to achieve the desired therapeutic effect, and gradually increase the dosage until the desired effect is achieved. A "therapeutically effective amount" refers to the concentration of a compound sufficient to induce the desired therapeutic effect. It is generally understood that the effective amount of a compound will vary depending on the subject's weight, sex, age, and medical history. Other factors that affect the effective amount may include, but are not limited to, the severity of the patient's condition, the disorder being treated, the stability of the compound, and, if desired, other types of therapeutic agents administered together with the compound of the present disclosure. A larger total dose can be delivered by multiple administrations of the drug. Methods for determining efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) Harrison's Principles of Internal Medicine 13 ed., 1814-1882, incorporated herein by reference).
[0222] Generally, a suitable daily dose of an active compound used in the compositions and methods of the present disclosure will be that amount of the compound that is the lowest dose effective to produce a therapeutic effect. Such an effective dose will generally depend upon the factors described above.
[0223] If desired, the effective daily dose of the active compound may be administered as one, two, three, four, five, six, or more subdoses administered separately at appropriate intervals throughout the day, optionally in unit dosage forms. In certain embodiments of the present disclosure, the active compound may be administered two or three times a day. In a preferred embodiment, the active compound is administered once a day.

[0230] definition Unless otherwise defined herein, scientific and technical terms used in this application shall have the meanings commonly understood by those of ordinary skill in the art. Generally, the terms used in connection with, and techniques relating to, chemistry, cell and tissue culture, molecular biology, cell and cancer biology, neurobiology, neurochemistry, virology, immunology, microbiology, pharmacology, genetics, and protein and nucleic acid chemistry described herein are those well known and commonly used in the art.
[0231] The methods and techniques of the present disclosure are generally performed, unless otherwise indicated, according to conventional methods known in the art and as described in various general and more specific references cited and discussed throughout the specification, e.g., "Principles of Neural Science," McGraw-Hill Medical, New York, NY (2000); Motulsky, "Intuitive Biostatistics," Oxford University Press, Inc. (1995); Lodish et al., "Molecular Cell Biology, 4t h ed.”, WH Freeman & Co., New York (2000); Griffiths et al., “Introduction to Genetic Analysis, 7th ed.”, WH Freeman & Co., NY (1999); and Gilbert et al., “Developmental Biology, 6t h ed,” Sinauer Associates, Inc., Sunderland, MA (2000).
[0232] Chemical terms used herein, unless otherwise defined herein, are used in accordance with conventional usage in the art, as exemplified by "The McGraw-Hill Dictionary of Chemical Terms," Parker S., Ed., McGraw-Hill, San Francisco, CA (1985).
[0233] All of the above, and any other publications, patents and published patent applications mentioned in this application, are specifically incorporated herein by reference. In the case of conflict, the present specification, including its specific definitions, will control.
[0234] The term "agent" is used herein to refer to a chemical compound (e.g., an organic or inorganic compound, a mixture of compounds), a biopolymer (e.g., a nucleic acid, an antibody, e.g., a portion thereof, as well as humanized, chimeric, and human antibodies, and monoclonal antibodies, a protein or a portion thereof, e.g., a peptide, a lipid, a carbohydrate), or an extract made from biological material such as a bacterial, plant, fungal, or animal (especially mammalian) cell or tissue. Agents include, for example, agents of known structure and agents of unknown structure.
[0235] The terms "patient," "subject," or "individual" are used interchangeably and refer to either a human or non-human animal. These terms include mammals, such as humans, primates, livestock animals (including cows, pigs, etc.), companion animals (e.g., dogs, cats, etc.), and rodents (e.g., mice and rats).
[0236] "Treating" a condition or patient refers to taking measures to obtain beneficial or desired results, including clinical results. Beneficial or desired clinical results can include, but are not limited to, alleviation or amelioration of one or more symptoms or conditions, whether detectable or undetectable, reduction in the extent of the disease, stabilization of the disease state (i.e., not worsening), prevention of the spread of the disease, delay or slowing of disease progression, improvement or palliation of the disease state, and remission (whether partial or total). "Treatment" can also mean prolonging survival as compared to expected survival if not receiving treatment.
[0237] The term "preventing," when used in reference to a condition, e.g., local recurrence (e.g., pain), a disease such as cancer, a complex syndrome such as heart failure, or any other medical condition, is art-recognized and well understood in the art, and includes administration of a composition that reduces the frequency of, or delays the onset of, symptoms of the medical condition in a subject compared to subjects not receiving the composition. Thus, preventing cancer includes, for example, reducing, by a statistically and / or clinically significant amount, the number of detectable cancerous growths in a population of patients receiving prophylactic treatment compared to an untreated control population, and / or delaying the appearance of detectable cancerous growths in a treated population versus an untreated control population.
[0238] "Administering" or "administration" of a substance, compound, or agent to a subject can be accomplished using one of a variety of methods known to those of skill in the art. For example, a compound or agent can be administered intravenously, intraarterially, intradermally, intramuscularly, intraperitoneally, subcutaneously, intraocularly, sublingually, orally (by ingestion), intranasally (by inhalation), intraspinally, intracerebrally, and transdermally (e.g., by absorption through the skin's channels). A compound or agent can also be suitably introduced via a rechargeable or biodegradable polymeric device or other device, such as a patch and pump, or formulation that provides extended, sustained, or controlled release of the compound or agent. Administering can also be performed, for example, once, multiple times, and / or over one or more extended periods of time.
[0239] The appropriate method of administering a substance, compound, or agent to a subject also depends, for example, on the age and / or health of the subject, and the chemical and biological properties of the compound or agent (e.g., solubility, digestibility, bioavailability, stability, and toxicity). In some embodiments, the compound or agent is administered orally to the subject, for example, by ingestion. In some embodiments, the orally administered compound or agent is in an extended- or sustained-release formulation or is administered using such a sustained- or sustained-release device.
[0240] As used herein, the phrase "conjoint administration" refers to any form of administration of two or more different therapeutic agents, in which a second agent is administered while a previously administered therapeutic agent is still effective in the body (e.g., the two agents are effective in a patient simultaneously, which may involve a synergistic effect of the two agents). For example, the different therapeutic compounds can be administered simultaneously or sequentially, in the same formulation or in separate formulations. Thus, an individual receiving such treatment can benefit from the combined effect of the different therapeutic agents.
[0241] A "therapeutically effective amount" or "therapeutically effective dose" of a drug or agent is an amount of drug or agent that has the intended therapeutic effect when administered to a subject. The full therapeutic effect does not necessarily occur by administration of one dose, but may occur only after administration of a series of doses. Thus, a therapeutically effective amount can be administered in one or more administrations. The precise effective amount required for a subject depends, for example, on the subject's size, health, and age, and the nature and extent of the condition being treated, such as cancer or MDS. Those skilled in the art can easily determine the effective amount for a given situation by routine experimentation.
[0242] As used herein, the term "optional" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes both the occurrence and non-occurrence of the event or circumstance. For example, "optionally substituted alkyl" refers to cases where alkyl can be substituted and cases where alkyl is not substituted.
[0243] It is understood that the substituents and substitution patterns on the compounds of the present disclosure can be selected by those skilled in the art to result in chemically stable compounds that can be easily synthesized from readily available starting materials by techniques known in the art and the methods described below.

Carbocycles include bicyclic molecules in which one, two, three, or more atoms are shared between the two rings. The term "fused carbocycle" refers to a bicyclic carbocycle in which each ring shares two adjacent atoms with the other ring. Each ring in a fused carbocycle can be selected from saturated, unsaturated, and aromatic rings. In a typical embodiment, an aromatic ring, e.g., phenyl, can be fused to a saturated or unsaturated ring, e.g., cyclohexane, cyclopentane, or cyclohexene. Where valences permit, any combination of saturated, unsaturated, and aromatic bicyclic rings is included in the definition of carbocycle. Exemplary "carbocycles" include cyclopentane, cyclohexane, bicyclo[2.2.1]heptane, 1,5-cyclooctadiene, 1,2,3,4-tetrahydronaphthalene, bicyclo[4.2.0]oct-3-ene, naphthalene, and adamantane.

[0275] The term "cycloalkyl" includes substituted or unsubstituted non-aromatic monocyclic ring structures, preferably 4-8 membered rings, more preferably 4-6 membered rings. The term "cycloalkyl" also includes polycyclic ring systems having two or more rings in which two or more carbons are common to two adjacent rings, at least one of which is cycloalkyl and contains substituents (e.g., R 100 ) is attached to the cycloalkyl ring; for example, the other rings can be cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heteroaryl, and / or heterocyclyl. Heteroaryl groups include, for example, pyrrole, furan, thiophene, imidazole, oxazole, thiazole, pyrazole, pyridine, pyrazine, pyridazine, pyrimidine, benzodioxane, tetrahydroquinoline, and the like.

Thus, the ether substituent of a hydrocarbyl group may be hydrocarbyl-O-. Ethers may be symmetrical or asymmetrical. Examples of ethers include, but are not limited to, heterocycle-O-heterocycle and aryl-O-heterocycle. Ethers include "alkoxyalkyl" groups, which may be represented by the general formula alkyl-O-alkyl.

[0279] The terms "heteroarylalkyl," "hetaralkyl," and "heteroaralkyl," as used herein, refer to an alkyl group substituted with a hetaryl group.
[0280] As used herein, the term "heteroaryl" refers to a single aromatic ring having at least one non-carbon atom in the ring, which atom may be selected from oxygen, nitrogen, and sulfur, and "heteroaryl" can include multiple fused ring systems having at least one such aromatic ring. Multiple fused ring systems are further described. Thus, "heteroaryl" can include a single aromatic ring having about 1 to 6 carbon atoms and about 1 to 4 heteroatoms selected from oxygen, nitrogen, and sulfur. The sulfur and nitrogen atoms can also be present in oxidized form, provided the ring is aromatic. Examples of heteroaryl ring systems include, but are not limited to, pyridyl, pyrimidinyl, oxazolyl, or furyl. In some embodiments, "heteroaryl" includes polycondensed ring systems (e.g., ring systems containing 2, 3, or 4 rings), and heteroaryl groups defined above can form polycondensed ring systems through fusion with at least one ring selected from heteroaryls (e.g., used to form 1,8-naphthyridinyl), heterocycles (e.g., used to form 1,2,3,4-tetrahydro-1,8-naphthyridinyl), carbocycles (e.g., used to form 5,6,7,8-tetrahydroquinolyl), and aryls (e.g., used to form indazolyl). Thus, a heteroaryl (a single aromatic ring or a polycondensed ring system) can have about 1 to 20 carbon atoms and about 1 to 6 heteroatoms in the heteroaryl ring. Such polycondensed ring systems can be such that the carbocyclic or heterocyclic portion of the fused ring can be substituted with one or more (e.g., 1, 2, 3, or 4) oxo groups. The rings of a multiply fused ring system may be connected to each other through fused, spiro, and bridged bonds, provided that valency requirements are met. The individual rings of a multiply fused ring system may be connected to each other in any order. The point of attachment to a heteroaryl or heteroaryl multiply fused ring system may be at any suitable atom of the heteroaryl or heteroaryl multiply fused ring system, including carbon atoms and heteroatoms (e.g., nitrogen). Additionally, heteroaryls of a particular atom range (e.g., (C5-C6)) may be used. 10When a heteroaryl is referred to, the atom range is to be understood as being in reference to the total number of ring atoms of the heteroaryl and includes carbon atoms and heteroatoms. For example, C heteroaryl may include thiazolyl, and C 10 Heteroaryl may include quinolinyl. Examples of heteroaryl include, but are not limited to, pyridyl, pyrrolyl, pyrazinyl, pyrimidinyl, pyridazinyl, pyrazolyl, thienyl, indolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, furyl, oxadiazolyl, thiadiazolyl, quinolyl, isoquinolyl, benzothiazolyl, benzoxazolyl, indazolyl, quinoxalyl, quinazolyl, 5,6,7,8-tetrahydroisoquinolinyl, benzofuranyl, benzimidazolyl, thianaphthenyl, pyrrolo[2,3-b]pyridinyl, quinazolinyl-4(3H)-one, triazolyl, 4,5,6,7-tetrahydro-1H-indazole, and 3b,4,4a,5-tetrahydro-1H-cyclopropa[3,4]cyclopenta[1,2-c]pyrazole.

Unless otherwise specified, a heterocyclyl group has from 5 to about 20 ring atoms, e.g., from 3 to 12 ring atoms, e.g., from 5 to 10 ring atoms. Thus, the term includes a single saturated or partially unsaturated ring (e.g., a 3-, 4-, 5-, 6-, or 7-membered ring) having from about 1 to 6 ring carbon atoms and from about 1 to 3 ring heteroatoms selected from oxygen, nitrogen, and sulfur in the ring. Rings in a poly-fused ring system may be connected to each other through fused, spiro, and bridged bonds, provided valency requirements are met. Examples of heterocycles include azetidine, aziridine, imidazolidine, morpholine, oxirane (epoxide), oxetane, piperazine, piperidine, pyrazolidine, piperidine, pyrrolidine, pyrrolidinone, tetrahydrofuran, tetrahydrothiophene, dihydropyridine, tetrahydropyridine, quinuclidine, N-bromopyrrolidine, N-chloropiperidine, and the like.
[0282] The term "hydrocarbyl," as used herein, refers to a group that is bonded through a carbon atom that has no =0 or =S substituents and typically has at least one carbon-hydrogen bond and a primarily carbon backbone, but may optionally contain heteroatoms. Thus, groups such as methyl, ethoxyethyl, 2-pyridyl, and even trifluoromethyl are considered hydrocarbyl for purposes of this application, while substituents such as acetyl (which has an =0 substituent on the connecting carbon) and ethoxy (which is connected through an oxygen rather than a carbon) are not.

"Lower alkyl," for example, refers to alkyl groups containing 10 or fewer carbon atoms, preferably 6 or fewer carbon atoms. In certain embodiments, an acyl, acyloxy, alkyl, alkenyl, alkynyl, or alkoxy substituent as defined herein is a lower acyl, lower acyloxy, lower alkyl, lower alkenyl, lower alkynyl, or lower alkoxy, respectively, whether they appear alone or in combination with other substituents, such as in descriptions of hydroxyalkyl and aralkyl (where, for example, atoms in an aryl group are not counted when counting carbon atoms in an alkyl substituent).
[0285] The terms "polycyclyl," "polycycle," and "polycyclic" refer to two or more rings (e.g., cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heteroaryl, and / or heterocyclyl) in which two or more atoms are common to two adjacent rings, e.g., the rings are "fused rings."
