[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the benefit of Korean Patent Application No. 10-2022-0147897, filed on November 8, 2022, which is hereby incorporated by reference in its entirety. Background Art
[0003] Stimulator of interferon genes (STING) is a low molecular weight protein that is currently attracting much 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 IFNs and other inflammatory cytokines, triggering 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). In addition, STING activates signal transducer and activator of transcription 6 (STAT6) and 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 trigger the expression of cytokines, causing T cell-mediated innate immune responses, thereby inhibiting cancer cell growth. However, systemic delivery of STING agonists can cause widespread inflammation.
[0004] Various STING agonists have been tested in preclinical and clinical settings. These agonists are being developed through various strategies, including CDN (cyclic dinucleotide) compounds (ADU-S100, BI-STING, GSK532, JNJ-4412, SB11285, MK-1454, TAK676, etc.), bacterial vectors (SYNB1891, STACT-TREX-1), non-cyclic dinucleotide (CDN) compounds (ALG-031048, JNJ-6196, MK-2118, MSA-1, MSA-2, CRD-5500, etc.), nanovaccines (PC7ANP, cGAMP-NP, etc.), and ADCs (XMT-2056, TAK500, etc.).
[0005] The most widely used preclinical compound, DMXAA (a vascular disruptor), was clinically used in combination with paclitaxel and carboplatin, but its efficacy was demonstrated to be lacking in Phase 3. Furthermore, ADU-S100, the first clinically used STING agonist, was discontinued in 2020.
[0006] Examples of STING agonists are disclosed in, for example, WO 2021 / 014365 (macrocyclic compounds as STING agonists), and US 2021 / 0139473 (heterocyclic amide compounds as protein modulators), US 2022 / 0073509 (heterocyclic compounds as STING activators), and KR 2022-0024467 (heterocyclic STING agonists), each of which is incorporated herein by reference in its entirety.
[0007] However, existing STING agonists appear to exhibit only limited bioavailability and require local administration to tumors due to overactivation of cytokine expression, or must be used in combination with other compounds. Therefore, there remains a need to develop therapeutically effective STING agonists. BRIEF DESCRIPTION OF THE DRAWINGS

[0241] Pharmaceutical composition
[0242] The compositions and methods of the present disclosure can be used to treat individuals in need. 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, it is preferred to administer a composition or compound in the form of a pharmaceutical composition, which comprises, for example, 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, such as water or physiologically buffered saline, or other solvents or vehicles, such as glycols, glycerol, oils (such as olive oil) or injectable organic esters. In a preferred embodiment, when such pharmaceutical compositions are used to administer humans, especially for invasive routes of administration (i.e., avoiding routes of transmission or diffusion through epithelial barriers, such as injection or implantation), the aqueous solution is pyrogen-free, or substantially pyrogen-free. Excipients (e.g.) can be selected to achieve delayed release of the agent or selectively target one or more cells, tissues or organs. The pharmaceutical composition can be in unit dosage form, such as tablets, capsules (including spray-on capsules and gelatin capsules), granules, lyophilized products for reconstitution, powders, solutions, syrups, suppositories, injections, etc. The composition can also be presented in a transdermal delivery system (eg, a skin patch).The composition can also be presented in a solution suitable for topical administration, such as an emulsion, cream, or ointment.
[0243] Pharmaceutically acceptable carriers may contain physiologically acceptable agents, for example, to stabilize compounds such as compounds of the present disclosure, increase their solubility, or increase their absorption. Such physiologically acceptable agents include, for example, carbohydrates such as glucose, sucrose, or polydextrose; antioxidants such as ascorbic acid or glutathione; chelating agents, low molecular weight proteins, or other stabilizers or excipients. The choice of pharmaceutically acceptable carriers (including physiologically acceptable agents) depends, for example, on the route of administration of the composition. The formulation or pharmaceutical composition may be a self-emulsifying drug delivery system or a self-microemulsifying drug delivery system. The pharmaceutical composition (formulation) may also be a liposome or other polymer matrix, into which compounds of the present disclosure may be incorporated. Liposomes (e.g., comprising phospholipids or other lipids) are physiologically acceptable and metabolizable non-toxic carriers that are relatively simple to prepare and administer.
[0244] As used herein, the phrase "pharmaceutically acceptable" refers 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 problems or complications, commensurate with a reasonable benefit / risk ratio.
[0245] As used herein, the phrase "pharmaceutically acceptable carrier" 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 injurious to the patient. Some examples of substances 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 waxes; (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 glycerol, 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) ethanol; (20) phosphate buffer solution; and (21) other nontoxic compatible substances used in pharmaceutical formulations.
[0246] The pharmaceutical composition (formulation) can be administered to a subject by any of a variety of routes of administration, including, for example, oral administration (e.g., as a bolus solution in the form of an aqueous or non-aqueous solution or suspension, tablets, capsules (including sprinkler capsules and gelatin capsules), boluses, powders, granules, pastes applied to the tongue); absorption through the oral mucosa (e.g., sublingually); subcutaneously; transdermally (e.g., in the form of a patch applied to the skin); and topically (e.g., in the form of a cream, ointment, or spray applied to the skin). The compound can also be formulated for inhalation. In certain embodiments, the compound can simply be dissolved or suspended in sterile water. Details of appropriate routes of administration and compositions useful therefor may be found in U.S. Patent 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.
[0247] The formulation is preferably presented in unit dosage form and can be prepared by any method well known in the art of pharmaceutical preparation. The amount of active ingredient that can be combined with the carrier material to produce a single dosage form will depend on the host being treated and the specific mode of administration. The amount of active ingredient that can be combined with the carrier material to prepare a single dosage form will generally be the amount of compound that produces the therapeutic effect. This amount is generally (in percentage) in the range of about 1% to about 99% active ingredient, preferably about 5% to about 70%, and most preferably about 10% to about 30%.
[0248] Methods for preparing these formulations or compositions include the step of bringing into association the active compound (e.g., a compound of the present disclosure) with a carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately combining a compound of the present disclosure with a liquid carrier or a finely divided solid carrier, or both, and then, if necessary, shaping the product.
[0249] The oral formulations of the present disclosure may be in the form of capsules (including sprinkle capsules and gelatin capsules), cachets, pills, tablets, lozenges (using a flavored base, usually sucrose and gum arabic or tragacanth), lyophilizates, powders, granules, or solutions or suspensions in aqueous or non-aqueous liquids, or oil-in-water or water-in-oil liquid emulsions, or elixirs or syrups, or tablets (using an inert base, such as gelatin and glycerin, or sucrose and gum arabic) and / or mouthwashes, etc., each containing a predetermined amount of the compound of the present disclosure as the active ingredient. The composition or compound may also be administered in the form of a bolus, a syrup, or a paste.
[0250] To prepare solid dosage forms for oral administration (capsules (including spray-on capsules and gelatin capsules), tablets, pills, dragees, powders, granules, etc.), the active ingredient is mixed with one or more pharmaceutically acceptable carriers (e.g., sodium citrate or calcium hydrogen 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, alginates, gelatin, polyvinyl pyrrolidone, sucrose and / or gum arabic; (3) humectants, such as propylene glycol. (4) disintegrants such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retardants such as paraffin; (6) absorption accelerators such as quaternary ammonium compounds; (7) wetting agents such as cetyl alcohol and glycerol monostearate; (8) adsorbents such as kaolin and bentonite; (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. In the case of capsules (including spray-on capsules and gelatin capsules), tablets, and pills, the pharmaceutical composition may also include a buffering agent. Similar types of solid compositions may also be used as fillers in soft-filled and hard-filled gelatin capsules using excipients such as lactose (milk sugar) and high molecular weight polyethylene glycols.
[0251] Tablets can be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared using a binder (e.g., gelatin or hydroxypropylmethylcellulose), a lubricant, an inert diluent, a preservative, a disintegrant (e.g., sodium starch glycolate or cross-linked sodium carboxymethylcellulose), a surfactant, or a dispersant. Molded tablets can be made by molding a mixture of the powdered compound moistened with an inert liquid diluent in a suitable machine.
[0252] Tablets and other solid dosage forms of pharmaceutical compositions (e.g., dragees, capsules (including sprinkle capsules and gelatin capsules), pills, and granules) may optionally be scored or prepared with coatings and shells (e.g., enteric coatings and other coatings well known in the pharmaceutical formulation art). They may also be formulated using, for example, hydroxypropylmethylcellulose in varying proportions to provide a desired release profile, other polymer matrices, liposomes, and / or microspheres to provide slow or controlled release of the active ingredient therein. They may be sterilized, for example, by filtration through a bacteria-retaining filter or by incorporating a sterilizing agent, in the form of sterile solid compositions that can be dissolved in sterile water or some other sterile injectable medium prior to use. These compositions may also optionally contain opacifying agents and may be compositions that release the active ingredient only or preferentially in a certain portion of the gastrointestinal tract in an optionally delayed manner. Examples of embedding compositions that may be used include polymeric substances and waxes. The active ingredient may also be microencapsulated, as appropriate, with one or more of the above-mentioned excipients.
[0253] Liquid dosage forms suitable for oral administration include pharmaceutically acceptable emulsions, lyophilizates for reconstitution, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active ingredient, the liquid dosage form may contain inert diluents commonly used in the art, such as water or other solvents, cyclodextrins and their derivatives, solubilizers, and emulsifiers, such as ethanol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (specifically, cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil, and sesame oil), glycerol, tetrahydrofuranol, polyethylene glycol, and fatty acid esters of sorbitan, and mixtures thereof.
[0254] 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.
[0255] Suspensions, in addition to the active compounds, may contain suspending agents in the form of, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and astragalus, and mixtures thereof.
[0256] 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 any preservatives, buffers, or propellants that may be required.
[0257] Ointments, pastes, creams and gels may contain, in addition to the active compounds, excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicone, bentonite, silicic acid, talc and zinc oxide, or mixtures thereof.
[0258] In addition to the active compound, powders and sprays may contain excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays may additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, for example butane and propane.
[0259] Transdermal patches have the additional advantage of providing control of the compound of the present disclosure to the delivery of 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 transdermal amount of the compound. The rate of this flow can be controlled by providing a rate-controlled membrane or by dispersing the compound in a polymer matrix or gel.
[0260] As used herein, the phrase "parenteral administration" or "administered parenterally" means modes of administration other than enteral and topical administration, usually injection, and includes, but is not limited to, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcutaneous, intraarticular, subcapsular, subarachnical, intraspinal, and intrasternal injection and infusion. Pharmaceutical compositions suitable for parenteral administration comprise one or more active compounds and one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous 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.
[0261] 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 (e.g., olive oil), and injectable organic esters (e.g., ethyl oleate). Proper fluidity can be maintained, for example, by the use of coating materials (e.g., lecithin), by maintaining the required particle size in the case of dispersions, and by the use of surfactants.
[0262] These compositions can also contain adjuvants, such as preservatives, wetting agents, emulsifiers and dispersants. Prevention of microbial action can be ensured by including various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol sorbic acid, etc. It may also be necessary to include isotonic agents, such as sugars, sodium chloride, etc. in the composition. In addition, prolonged absorption of injectable pharmaceutical forms can be achieved by including agents that delay absorption (such as aluminum monostearate and gelatin).
[0263] In some cases, in order to prolong the effect of a drug, it is necessary to slow down the absorption of a drug injected subcutaneously or intramuscularly. This can be achieved by using a liquid suspension of a crystalline or amorphous substance with poor water solubility. The absorption rate of a drug depends on its dissolution rate, which in turn can be determined by the size of the crystals and the crystalline form. Alternatively, parenteral drug forms can delay absorption by dissolving or suspending the drug in an oily vehicle.
[0264] Injectable depot formulations are made by forming a microencapsulation matrix of the target compound with a biodegradable polymer such as polylactide-polyglycolide. Depending on the drug-to-polymer ratio and the properties of the specific polymer used, the drug release rate can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Injectable depot formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues.
[0265] For use in the disclosed methods, the active compound can be administered directly or in the form of a pharmaceutical composition containing, for example, 0.1 to 99.5% (more preferably 0.5 to 90%) active ingredient and a pharmaceutically acceptable carrier.
[0266] The introduction method can also be provided by refillable or biodegradable devices. In recent years, a variety of slow-release polymeric devices have been developed and tested in vivo for the controlled delivery of drugs, including protein biopharmaceuticals. A variety of biocompatible polymers, including hydrogels, including biodegradable and non-degradable polymers, can be used to form inserts that continuously release compounds at specific target sites.
[0267] Actual dosage levels of the active ingredients in the pharmaceutical compositions may be varied so as 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.
[0268] The selected dosage concentration will depend upon a variety of factors, including the activity of the specific compound or combination of compounds employed, or their esters, salts, or amides; the route of administration; the time of administration; the rate of excretion of the specific compound being employed; other drugs, compounds, and / or materials used in combination with the specific compound employed; the age, sex, weight, condition, general health, and prior medical history of the patient being treated; and like factors well known in the medical arts.
[0269] A physician or veterinarian of ordinary skill can easily determine and prescribe the therapeutically effective amount of the desired pharmaceutical composition. For example, a physician or veterinarian can start administering a 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" means a concentration of the compound sufficient to cause the desired therapeutic effect. It is generally understood that the effective amount of a compound will vary according to the subject's weight, sex, age, and medical history. Other factors affecting the effective amount may include, but are not limited to, the severity of the patient's condition, the condition being treated, the stability of the compound, and another type of therapeutic agent administered together with the compound of the present invention, if necessary. A larger total dose can be delivered by multiple administrations of the agent. Methods for determining efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) "Harrison's Principles of Internal Medicine", 13th edition, 1814-1882, incorporated herein by reference).
[0270] In general, a suitable daily dose of the active compound used in the compositions and methods of the present disclosure will be the amount of the compound that is the lowest dose effective to produce a therapeutic effect. This effective dose will generally depend on the factors described above.
[0271] If desired, the effective daily dose of the active compound may optionally be administered in unit dosage form as one, two, three, four, five, six or more sub-doses administered at appropriate intervals throughout the day. In certain embodiments of the present disclosure, the active compound may be administered twice or three times daily. In a preferred embodiment, the active compound will be administered once daily.
[0272] Patients receiving such treatment are any animal in need thereof, including primates, particularly humans; and other mammals, such as horses, cattle, pigs, sheep, cats, and dogs; and pets in general.
[0273] In certain embodiments, the compounds of the present disclosure may be administered alone or in combination with another type of therapeutic agent.

[0279] Unless otherwise defined herein, the scientific and technical terms used in this application shall have the meanings commonly understood by those of ordinary skill in the art. Generally, the nomenclature used in connection with the 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 and their techniques are those well known and commonly used in the art.
[0280] The methods and techniques of the present disclosure are generally performed according to conventional methods well known in the art and as described in various general and more specific references that are cited and discussed throughout the present specification unless otherwise indicated. See, 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, 4th ed., W.H. Freeman & Co., New York (2000); Griffiths et al., Introduction to Genetic Analysis, 7th ed., W.H. Freeman & Co., NY (1999); and Gilbert et al., Developmental Biology, 6th ed., Sinauer Associates, Sunderland, MA (1996). Associates, Inc., Sunderland, MA) (2000).
[0281] Unless otherwise defined herein, chemical terms used herein are used according to conventional usage in the art as exemplified by “The McGraw-Hill Dictionary of Chemical Terms,” Parker, S., ed., McGraw-Hill, San Francisco, CA (1985).
[0282] All of the above and any other publications, patents, and published patent applications mentioned in this application are expressly incorporated herein by reference. In case of conflict, the present specification, including its specific definitions, will control.
[0283] The term "pharmaceutical agent" is used herein to refer to a chemical compound (e.g., an organic or inorganic compound, a mixture of compounds), a biological macromolecule (e.g., a nucleic acid, an antibody (including portions thereof), and humanized, chimeric, and human antibodies and monoclonal antibodies, a protein or a portion thereof, such as a peptide, lipid, or carbohydrate), or an extract made from a biological material (e.g., a bacterial, plant, fungal, or animal (particularly mammalian) cell or tissue). Pharmaceutical agents include, for example, agents whose structures are known and agents whose structures are unknown.
[0284] "Patient," "subject," or "individual" are used interchangeably and refer to a human or non-human animal. These terms include mammals, such as humans, primates, livestock animals (including bovines, porcines, etc.), companion animals (such as canines, felines, etc.), and rodents (such as mice and rats).
[0285] "Treating" a condition or patient means taking steps to obtain a favorable or desired result, including a clinical result. For the purposes of this disclosure, favorable or desired clinical results include, but are not limited to, alleviating or ameliorating one or more symptoms or conditions, reducing the severity of the disease, stabilizing the disease state (i.e., not worsening), preventing the spread of the disease, delaying or slowing the progression of the disease, improving or alleviating the disease state, and remission (whether partial or complete), whether detectable or undetectable. "Treatment" can also mean prolonging survival as compared to expected survival if not receiving treatment.
[0286] The term "prevent" is art-recognized and well understood in the art when used with respect to conditions such as local recurrences (e.g., pain), diseases such as cancer, complex syndromes such as heart failure, or any other medical condition, and includes administering a composition that reduces the frequency of symptoms of a medical condition in a subject or delays its onset relative to a subject not receiving the composition. Thus, preventing cancer includes, for example, reducing the number of detectable cancerous growths in a patient population receiving prophylactic treatment relative to an untreated control population; and / or delaying the appearance of detectable cancerous growths in a treated population (e.g., to a statistically and / or clinically significant amount) relative to an untreated control population.
[0287] "Administering" a substance, compound, or agent to a subject can be performed using one of a variety of methods known to those skilled in the art. For example, the compound or agent can be administered intravenously, intraarterially, intradermally, intramuscularly, intraperitoneally, subcutaneously, ocularly, sublingually, orally (by ingestion), intranasally (by inhalation), intraspinal, intracranially, and transdermally (by absorption, e.g., through a skin duct). The compound or agent can also be suitably introduced via a refillable or biodegradable polymer device or other device, such as a patch and pump or formulation that provides for extended, slowed, or controlled release of the compound or agent. Administration can also be performed, for example, once, multiple times, and / or over one or more extended periods.
[0288] The appropriate method of administering a substance, compound, or agent to a subject will also depend on, for example, the age and / or physical condition 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 a subject, for example, by ingestion. In some embodiments, the orally administered compound or agent is in the form of an extended-release or slow-release formulation, or is administered using a device for such slow-release or extended-release.
[0289] As used herein, the phrase "administered in combination" refers to any form of administration of two or more different therapeutic agents such that the previously administered therapeutic agent is still effective in the body at the same time as the second agent is administered (e.g., both agents are effective in the patient's body at the same time, which may include a synergistic effect of the two agents). For example, different therapeutic compounds can be administered simultaneously or sequentially in the same formulation or in separate formulations. Thus, individuals receiving such treatments may benefit from the combined effects of the different therapeutic agents.
[0290] A "therapeutically effective amount" or "therapeutically effective dose" of a drug or pharmaceutical agent is an amount of the drug or pharmaceutical agent that will have the intended therapeutic effect when administered to a subject. The full therapeutic effect may not occur with the administration of a single dose, and may occur only after a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations. The precise effective amount required for a subject will depend, 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. One skilled in the art can readily determine the effective amount for a given situation by routine experimentation.
[0291] 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 instances where the event or circumstance occurs and instances where it does not. For example, "optionally substituted alkyl" refers to an alkyl group that can be substituted as well as instances where the alkyl group is unsubstituted.
[0292] It will be understood that substituents and substitution patterns on the compounds of the present disclosure can be selected by one of ordinary skill in the art to produce chemically stable compounds that can be readily synthesized from readily available starting materials by techniques known in the art and the methods given below.
