Description

A bifunctional chimeric heterocyclic compound for targeting degradation of androgen receptor and its use Technical Field

[0001] The present invention belongs to the field of pharmaceutical technology, and specifically relates to a compound represented by general formula (I) or its stereoisomers, tautomers, nitrogen oxides, hydrates, solvates, metabolites, pharmaceutically acceptable salts and prodrugs, as well as the use of such compounds as androgen receptor (AR) degraders. Background Art

[0002] The androgen receptor (AR) is a nuclear hormone receptor structurally divided into an N-terminal activation domain (NTD), a DNA-binding domain (DBD), and a ligand-binding domain (LTD). It regulates the expression of genes that drive prostate cancer, making AR inhibition an effective treatment for prostate cancer. Currently available AR inhibitors, such as enzalutamide and bicalutamide, primarily exert their inhibitory effects by interacting with the AR ligand-binding domain (LTD). However, some patients develop resistance to AR during treatment due to AR splice variants (AR-Vs) lacking the LTD. Preclinical studies have shown that AR splice variants can accelerate the progression of enzalutamide-resistant prostate cancer, making addressing AR resistance a key clinical concern. Furthermore, a growing body of research suggests that AR plays a crucial role in hormone-related diseases such as alopecia, acne, and benign prostatic hyperplasia (BPH).

[0003] PROTAC (proteolysis targeting chimera) molecules are a class of bifunctional compounds that can simultaneously bind to target proteins and E3 ubiquitin ligases. Such compounds can be recognized by the cell's proteasome, causing the degradation of the target protein, and can effectively reduce the content of the target protein in the cell. By introducing ligands that can bind to different target proteins into PROTAC molecules, PROTAC technology can be applied to the treatment of various diseases. This technology has also received widespread attention in recent years. Arvinas has developed an AR protein degrader ARV-110 for the treatment of metastatic castration-resistant prostate cancer (mCRPC). It is currently in the second phase of clinical research and development, and the latest clinical data show good efficacy and safety.

[0004] Currently, approved anti-androgen receptor drugs on the market include enzalutamide, bicalutamide, and apalutamide. However, approximately 15% to 25% of prostate cancer patients do not respond to anti-androgen drugs, and approved drugs show excellent anti-cancer effects in the initial stage of administration, but continuous use will produce drug resistance, making them difficult to use again. Therefore, it is necessary to develop new targeted androgen receptor degraders for the treatment of diseases mediated by androgen receptors. Summary of the Invention

[0005] The present invention provides a novel compound with excellent efficacy, high bioavailability, and enhanced safety that inhibits and degrades the androgen receptor for use in treating androgen receptor-mediated diseases such as cancer, inflammatory diseases, or autoimmune diseases. The compound of the present invention exhibits excellent androgen receptor inhibition and / or degradation activity, good pharmacokinetic properties and bioavailability, oral administration, and a good safety profile. Therefore, the compound of the present invention has promising clinical application prospects.

[0056] Detailed description of the present invention

[0057] Definitions and General Terms

[0058] Certain embodiments of the present invention are now described in detail, examples of which are illustrated by the accompanying structural formulas and chemical formulae. The present invention is intended to encompass all substitutions, modifications, and equivalent technical solutions, which are all included within the scope of the invention as defined in the claims. Those skilled in the art will recognize that many methods and materials similar or equivalent to those described herein can be used to practice the present invention. The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the combined documents, patents, and similar materials differ from or contradict the present application (including but not limited to defined terms, term applications, described technologies, etc.), the present application shall prevail.

[0059] It will be further appreciated that certain features of the invention, which, for clarity, are described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which, for brevity, are described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.

[0060] Unless otherwise indicated, the following definitions used in the present invention shall apply. For purposes of the present invention, chemical elements are defined in accordance with the Periodic Table of the Elements, CAS version, and Handbook of Chemistry and Physics, 75th edition, 1994. In addition, general principles of organic chemistry may be found in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausalito: 1999, and "March's Advanced Organic Chemistry" by Michael B. Smith and Jerry March, John Wiley & Sons, New York: 2007, the entire contents of which are incorporated herein by reference.

[0061] Unless otherwise specified or clearly contradicted by context, the articles "a," "an," and "the" as used herein are intended to include "at least one" or "one or more." Thus, as used herein, these articles refer to one or more than one (i.e., at least one) of the objects. For example, "a component" refers to one or more components, i.e., more than one component may be contemplated for use or use in implementing the described embodiment.

[0062] The term "stereoisomers" refers to compounds that have identical chemical constitution but differ in the way the atoms or groups are arranged in space. Stereoisomers include enantiomers, diastereomers, conformers (rotamers), geometric isomers (cis / trans isomers), atropisomers, and the like.

[0063] The term "chiral molecule" refers to a molecule that is non-superimposable on its mirror image; whereas "achiral molecule" refers to a molecule that is superimposable on its mirror image.

[0064] The term "enantiomers" refers to two non-superimposable isomers of a compound that are mirror images of each other.

[0065] The term "racemate" or "racemic mixture" refers to an equimolar mixture of two enantiomers, which mixture lacks optical activity.

[0066] The term "diastereoisomer" refers to stereoisomers that have two or more chiral centers and whose molecules are not mirror images of each other. Diastereoisomers have different physical properties, such as melting points, boiling points, spectral properties, and reactivity. Diastereomeric mixtures can be separated by high-resolution analytical procedures such as electrophoresis and chromatography, for example, HPLC.

[0067] The stereochemical definitions and conventions used herein generally follow those of SP Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S, "Stereochemistry of Organic Compounds", John Wiley & Sons, Inc, New York, 1994. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to indicate the absolute configuration of the molecule about one or more of its chiral centers. The prefixes d and l or (+) and (-) are the symbols used to designate the rotation of plane-polarized light caused by the compound, where (-) or l indicates that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. A specific stereoisomer is an enantiomer, and a mixture of such isomers is called an enantiomeric mixture. A 50:50 mixture of enantiomers is called a racemic mixture or racemate and can occur when there is no stereoselectivity or stereospecificity in a chemical reaction or process.

[0068] Any asymmetric atom (e.g., carbon, etc.) of the compounds disclosed herein can exist in a racemic or enantiomerically enriched form, such as in the (R)-, (S)-, or (R,S)-configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in terms of the (R)- or (S)-configuration.

[0069] Depending on the choice of starting materials and process, the compounds of the present invention may exist as one of the possible isomers or as a mixture thereof, such as a racemate or a mixture of diastereoisomers (depending on the number of asymmetric carbon atoms). Optically active (R)- or (S)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the cycloalkyl substituents may be in the cis or trans configuration.

[0070] Any resulting mixture of stereoisomers can be separated into the pure or substantially pure geometric isomers, enantiomers, and diastereomers on the basis of the differences in the constituent physicochemical properties, for example, by chromatography and / or fractional crystallization.

[0071] Any racemate of the resulting final product or intermediate can be separated into its optical antipodes by methods familiar to those skilled in the art using known methods, such as by separating the diastereomeric salts obtained. The racemic products can also be separated by chiral chromatography, such as high performance liquid chromatography (HPLC) using a chiral adsorbent. In particular, enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Principles of Asymmetric Synthesis (2 nd Ed.Robert E.Gawley, Jeffrey Aube, Elsevier, Oxford, UK, 2012); Eliel, ELStereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); Wilen, SHTables of Resolving Agents and Optical Resolutions p.268 (ELEliel, Ed., Univ. of Notre Dame Press, Notre Dame, IN 1972); Chiral Separation Techniques: A Practical Approach (Subramanian, G. Ed., Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, Germany, 2007).

[0072] The term "tautomer" or "tautomeric form" refers to structural isomers of different energies that are interconvertible via a low energy barrier. If tautomerism is possible (e.g., in solution), a chemical equilibrium of the tautomers can be achieved. For example, proton tautomers (also known as prototropic tautomers) include interconversions via proton migration, such as keto-enol isomerization and imine-enamine isomerization.

[0073] "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 patients without excessive toxicity, irritation, allergic response or other problems and complications commensurate with a reasonable benefit / risk ratio, and are effective for their intended use.

Unless otherwise indicated, a substituent may be substituted at every possible position in the group. When more than one position in a given structure can be substituted with one or more of the specified substituents, the substituents may be the same or different at every possible position in the structure.

[0076] In addition, it should be noted that, unless otherwise explicitly stated, the description methods used in the present invention such as "each...independently is" and "...each independently is" and "...independently is" can be interchanged and should be understood in a broad sense. They can mean that in different groups, the specific options expressed by the same symbols do not affect each other, or that in the same group, the specific options expressed by the same symbols do not affect each other.

Pharmaceutically acceptable salts formed from non-toxic acids include, but are not limited to, inorganic acid salts formed by reaction with amino groups, such as hydrochlorides, hydrobromides, phosphates, sulfates, and perchlorates, and organic acid salts such as acetates, oxalates, maleates, tartrates, citrates, succinates, and malonates, or salts obtained by other methods described in the literature, such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, cyclopentylpropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, propionate, stearate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N + (C 1-4The present invention also contemplates quaternary ammonium salts formed by compounds of any group containing N. Water-soluble or oil-soluble or dispersed products can be obtained by quaternization. Alkali metal or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Pharmaceutically acceptable salts further include appropriate, non-toxic ammonium, quaternary ammonium salts and amine cations formed by counter-balancing ions, such as halides, hydroxides, carboxylates, sulfates, phosphates, nitrates, C1-C8 sulfonates and aromatic sulfonates. Although other salts can be used, for example, to separate or purify products, non-toxic physiologically acceptable salts are preferred.

[0104] The salts may be formed by conventional means, for example by reacting the free base form of the product with one or more equivalents of the appropriate acid in a solvent or medium in which the salt is insoluble or in a solvent such as one in which water is removed in vacuo, or by freeze-drying, or by exchanging the anion of an existing salt for another anion on a suitable ion exchange resin.

[0105] As used herein, a "solvate" refers to an association formed between one or more solvent molecules and a compound of the present invention. Solvents that form solvates include, but are not limited to, water, isopropanol, ethanol, methanol, dimethyl sulfoxide, ethyl acetate, acetic acid, ethanolamine, or mixtures thereof. The term "hydrate" refers to an association formed when the solvent molecule is water.

[0106] When the solvent is water, the term "hydrate" may be used. In one embodiment, one molecule of the compound of the present invention may be associated with one water molecule, such as a monohydrate; in another embodiment, one molecule of the compound of the present invention may be associated with more than one water molecule, such as a dihydrate; and in yet another embodiment, one molecule of the compound of the present invention may be associated with less than one water molecule, such as a hemihydrate. It should be noted that the hydrates of the present invention retain the biological effectiveness of the non-hydrated form of the compound.

[0107] The term "treating" any disease or condition, in some embodiments, refers to ameliorating the disease or condition (i.e., slowing, arresting, or alleviating the development of the disease or at least one clinical symptom thereof). In other embodiments, "treating" refers to alleviating or improving at least one physical parameter, including physical parameters that may not be perceived by the patient. In other embodiments, "treating" refers to regulating the disease or condition physically (e.g., stabilizing a perceptible symptom) or physiologically (e.g., stabilizing a physical parameter), or both. In yet other embodiments, "treating" refers to preventing or delaying the onset, occurrence, or worsening of a disease or condition.

[0108] The terms "prevent" or "prevention" refer to a reduction in the risk of acquiring a disease or disorder (i.e., halting the development of at least one clinical symptom of a disease in a subject who may be at risk or predisposed to the disease but has not yet experienced or displayed symptoms of the disease).

[0109] Unless otherwise stated, all suitable isotopic variations, stereoisomers, tautomers, solvates, metabolites, salts and pharmaceutically acceptable prodrugs of the compounds of the present invention are encompassed within the scope of the invention.

[0110] In structures disclosed herein, when the stereochemistry of any particular chiral atom is not indicated, all stereoisomers of the structure are contemplated and included as compounds disclosed herein. When stereochemistry is indicated by a solid wedge or dashed line representing a specific configuration, the stereoisomers of the structure are unambiguous and defined.

[0111] The "nitrogen oxides" of the compounds of the present invention are also included within the scope of the present invention. The nitrogen oxides of the compounds of the present invention can be prepared by oxidation of the corresponding nitrogen-containing basic substance using a conventional oxidizing agent (e.g., hydrogen peroxide) in the presence of an acid such as acetic acid at elevated temperatures, or by reaction with a peracid in a suitable solvent, such as peracetic acid in dichloromethane, ethyl acetate, or methyl acetate, or with 3-chloroperoxybenzoic acid in chloroform or dichloromethane.

[0112] The compound shown in formula (I), (II), (III), (IV) or (V) may exist in the form of a salt. In one embodiment, the salt refers to a pharmaceutically acceptable salt. The term "pharmaceutically acceptable" means that the substance or composition must be chemically and / or toxicologically compatible with the other ingredients comprising the formulation and / or the mammal to be treated therewith. In another embodiment, the salt is not necessarily a pharmaceutically acceptable salt and can be an intermediate for preparing and / or purifying the compound shown in formula (I), (II), (III), (IV) or (V) and / or for separating the enantiomer of the compound shown in formula (I), (II), (III), (IV) or (V).

[0113] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound, the basic or acidic moiety using conventional chemical methods. Generally speaking, such salts can be prepared by reacting the free acid form of these compounds with a stoichiometric amount of a suitable base (such as a hydroxide, carbonate, bicarbonate, etc. of Na, Ca, Mg or K), or by reacting the free base form of these compounds with a stoichiometric amount of a suitable acid. Such reactions are generally carried out in water or an organic solvent or a mixture of the two. Generally, where appropriate, a non-aqueous medium such as ether, ethyl acetate, ethanol, isopropanol or acetonitrile is used. Additional lists of suitable salts can be found, for example, in "Remington's Pharmaceutical Sciences", 20th edition, Mack Publishing Company, Easton, Pa., (1985); and "Handbook of Pharmaceutical Salts: Properties, Selection, and Use", Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).

[0180] Pharmaceutical compositions, formulations and administration of the compounds of the present invention

[0181] The present invention provides a pharmaceutical composition comprising a compound represented by Formula (I), (II), (III), (IV), or (V), or a stereoisomer thereof, a racemic or non-racemic mixture of the isomers, or a pharmaceutically acceptable salt or solvate thereof. In one embodiment of the present invention, the pharmaceutical composition further comprises at least one pharmaceutically acceptable carrier, adjuvant, or excipient, and optionally, other therapeutic and / or prophylactic ingredients.

[0182] The dosage form in which the compounds used in the methods of the present invention are administered will be determined by the particular compound chosen, the type of pharmacokinetic profile desired for the route of administration, and the condition of the patient.

[0183] Preparations suitable for oral, sublingual, intranasal or injection administration are prepared according to methods well known in the pharmaceutical art and contain at least one active compound. See, for example, REMINGTON'S PHARMACEUTICAL SCIENCES (16th ed. 1980).

[0184] In general, the formulations of the present invention include the active ingredient (a compound of Formula (I), (II), (III), (IV), or (V)), typically mixed with an excipient, diluted with an excipient, or encapsulated in a carrier that can be in the form of a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semisolid, or liquid material that acts as an excipient, carrier, or medium for the active ingredient. Thus, the formulation can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (either as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard capsules, gels, suppositories, sterile injectable solutions, and sterile encapsulated powders.

[0185] In the preparation of a formulation, it may be necessary to grind the active compound to provide an appropriate particle size prior to mixing with the other components. If the active compound is substantially insoluble, it is typically ground to a particle size of less than 200 mesh. If the active compound is substantially water-soluble, the particle size is adjusted by grinding to provide a uniform particle size distribution in the formulation, for example, about 40 mesh. In one embodiment of the invention, the particle size is approximately 0.1-100 μm.

[0186] Suitable carriers, adjuvants, and excipients are well known to those skilled in the art and are described in detail, for example, in Ansel HC et al., Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems (2004) Lippincott, Williams & Wilkins, Philadelphia; Gennaro AR et al., Remington: The Science and Practice of Pharmacy (2000) Lippincott, Williams & Wilkins, Philadelphia; and Rowe RC, Handbook of Pharmaceutical Excipients (2005) Pharmaceutical Press, Chicago.

[0187] As used herein, a "pharmaceutically acceptable excipient" refers to a pharmaceutically acceptable material, mixture, or vehicle that contributes to the consistency of a dosage form or pharmaceutical composition. Each excipient, when combined, must be compatible with the other ingredients of the pharmaceutical composition to avoid interactions that could significantly reduce the efficacy of the disclosed compounds upon administration to a patient and / or result in an unpharmaceutically acceptable pharmaceutical composition. Furthermore, each excipient must be pharmaceutically acceptable, e.g., possess a sufficiently high degree of purity.

[0188] Suitable pharmaceutically acceptable excipients will vary depending on the specific dosage form selected. In addition, pharmaceutically acceptable excipients may be selected based on their specific function in the composition. For example, certain pharmaceutically acceptable excipients may be selected to facilitate the production of a uniform dosage form. Certain pharmaceutically acceptable excipients may be selected to facilitate the production of a stable dosage form. Certain pharmaceutically acceptable excipients may be selected to facilitate the carrying or transport of the compound of the invention from one organ or part of the body to another organ or part of the body when administered to a patient. Certain pharmaceutically acceptable excipients may be selected to enhance patient compliance.

[0189] Some suitable excipient examples include lactose, glucose, sucrose, sorbitol, mannitol, starch, gum arabic, calcium phosphate, alginate, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinyl pyrrolidone, cellulose, water, syrup and methylcellulose. Suitable pharmaceutically acceptable excipients also include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants (such as talc, magnesium stearate and mineral oil), glidants, granulating agents, coating agents, wetting agents, solvents, cosolvents, suspending agents, emulsifiers, sweeteners, flavoring agents, taste masking agents, coloring agents, anti-caking agents, humectants, chelating agents, plasticizers, tackifiers, antioxidants, preservatives (such as methyl hydroxybenzoate and propyl hydroxybenzoate), stabilizers, surfactants and buffers. Those skilled in the art will recognize that certain pharmaceutically acceptable excipients can serve more than one function, and can provide alternative functions, depending on how much of the excipient is present in the formulation and which other excipients are present in the formulation. The compounds of the invention can be formulated using methods known in the art so as to provide quick, sustained, or delayed release of the active ingredient after administration to a patient.

[0190] The skilled person has the knowledge and skill in this area to enable them to select a suitable pharmaceutically acceptable excipient for the appropriate amount of the present invention. In addition, there are a large number of resources available to the skilled person that describe pharmaceutically acceptable excipients and are used to select suitable pharmaceutically acceptable excipients. Examples include Remington's Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press).

[0191] To prepare pharmaceutical compositions using the compounds described herein, pharmaceutically acceptable carriers can be solid or liquid carriers. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets, and suppositories. Powders and tablets can contain from about 5% to about 95% active ingredient. Suitable solid carriers are known in the art and include, for example, magnesium carbonate, magnesium stearate, talc, sugar, or lactose. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and methods for preparing various compositions can be found in: A. Gennaro (ed.), Remington's Pharmaceutical Sciences, 18 th ed., 1990, Mack Publishing Company Co., Easton, Pennsylvania.

[0192] Various carriers for configuring pharmaceutically acceptable compositions and known techniques for their preparation are disclosed in Remington: The Science and Practice of Pharmacy, 21st edition, 2005, ed. D. B. Troy, Lippincott Williams & Wilkins, Philadelphia, and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, the contents of each of which are incorporated herein by reference. The use of any conventional carrier, other than any carrier which is incompatible with the compounds of the invention, such as by producing any undesirable biological effect or by interacting in a deleterious manner with any other ingredient in the pharmaceutically acceptable composition, falls within the scope of the present invention.

[0193] The pharmaceutical compositions disclosed herein are prepared using techniques and methods known to those skilled in the art. A description of some common methods in the art can be found in Remington's Pharmaceutical Sciences (Mack Publishing Company).

[0198] The pharmaceutical compositions provided herein can be provided as compressed tablets, tablets, chewable lozenges, fast-dissolving tablets, composite compressed tablets, enteric-coated tablets, sugar-coated tablets, or film-coated tablets. Enteric-coated tablets are compressed tablets coated with a substance that resists the effects of gastric acid but dissolves or disintegrates in the intestines, thereby protecting the active ingredients from the acidic environment of the stomach. Enteric coatings include, but are not limited to, fatty acids, fats, phenyl salicylate, waxes, shellac, ammoniated shellac, and cellulose acetate phthalate. Sugar-coated tablets are compressed tablets surrounded by a sugar coating, which helps mask unpleasant tastes or odors and prevents tablet oxidation. Film-coated tablets are compressed tablets covered with a thin layer or film of a water-soluble substance. Film coatings include, but are not limited to, hydroxyethylcellulose, sodium carboxymethylcellulose, polyethylene glycol 4000, and cellulose acetate phthalate. Film coatings impart the same general properties as sugar coatings. Composite compressed tablets are compressed tablets produced through more than one compression cycle, including multilayer tablets and press-coated or dry-coated tablets.

[0199] Tablet dosage forms can be prepared from the active ingredient in powder, crystal or granular form alone or in combination with one or more carriers or excipients described herein, including binders, disintegrants, controlled release polymers, lubricants, diluents and / or colorants. Flavoring agents and sweeteners are particularly useful in forming chewable tablets and lozenges.

[0200] The pharmaceutical composition provided by the present invention can be provided in soft capsules or hard capsules, which can be prepared from gelatin, methylcellulose, starch or calcium alginate. The hard gelatin capsule, also known as dry-filled capsule (DFC), consists of two sections, one section inserted into the other, thus completely encapsulating the active ingredient. Soft elastic capsules (SEC) are soft, spherical shells, such as gelatin shells, which are plasticized by adding glycerol, sorbitol or similar polyols. The soft gelatin shells can contain preservatives to prevent microbial growth. Suitable preservatives are those as described in the present invention, including methylparaben and propylparaben, and sorbic acid. The liquid, semisolid and solid dosage forms provided by the present invention can be encapsulated in capsules. Suitable liquid and semisolid dosage forms include solutions and suspensions in propylene carbonate, vegetable oils or triglycerides. Capsules containing such solutions can be prepared as described in U.S. Pat. Nos. 4,328,245; 4,409,239 and 4,410,545. The capsules may also be coated as known to those skilled in the art to improve or sustain dissolution of the active ingredient.

[0201] The pharmaceutical compositions provided herein can be provided in liquid and semisolid dosage forms, including emulsions, solutions, suspensions, elixirs, and syrups. Emulsions are two-phase systems in which one liquid is completely dispersed in another liquid in the form of small globules, which can be oil-in-water or water-in-oil. Emulsions can include pharmaceutically acceptable non-aqueous liquids and solvents, emulsifiers, and preservatives. Suspensions can include pharmaceutically acceptable suspending agents and preservatives. Aqueous alcoholic solutions can include pharmaceutically acceptable acetals, such as di(lower alkyl) acetals of lower alkyl aldehydes, such as acetaldehyde diethyl acetal; and water-soluble solvents having one or more hydroxyl groups, such as propylene glycol and ethanol. Elixirs are clear, sweet-tasting hydroalcoholic solutions. Syrups are concentrated aqueous solutions of sugars, such as sucrose, and can also contain preservatives. For liquid dosage forms, for example, solutions in polyethylene glycol can be diluted with a sufficient amount of a pharmaceutically acceptable liquid carrier, such as water, for accurate and convenient administration.

[0202] The pharmaceutical compositions provided by the present invention can be formulated into any dosage form suitable for inhalation administration to a patient, such as a dry powder, an aerosol, a suspension or a solution composition. In one embodiment, the pharmaceutical compositions disclosed herein can be formulated into a dosage form suitable for inhalation administration to a patient using a dry powder. In another embodiment, the pharmaceutical compositions disclosed herein can be formulated into a dosage form suitable for inhalation administration to a patient via a nebulizer. The dry powder composition delivered to the lungs by inhalation typically comprises a fine powder of the compound disclosed herein and one or more fine powdered pharmaceutically acceptable excipients. Pharmaceutically acceptable excipients particularly suitable for use as dry powders are known to those skilled in the art and include lactose, starch, mannitol, and mono-, di- and polysaccharides. Fine powders can be prepared, for example, by micronization and grinding. In general, size-reduced (e.g., micronized) compounds can be prepared by a D 50 values ​​(e.g., measured by laser diffraction).

[0203] Pharmaceutical compositions suitable for transdermal administration can be prepared as discontinuous patches intended to remain in close contact with the patient's epidermis for an extended period of time. For example, the active ingredient can be delivered from the patch by iontophoresis as generally described in Pharmaceutical Research, 3(6), 318 (1986).

[0204] The pharmaceutical composition that is suitable for topical administration can be formulated into ointment, cream, suspension, lotion, powder, solution, paste, gel, spray, aerosol or oil.For example, ointment, cream and gel can configure with water or oil base, and applicable thickener and / or gel and / or solvent.Such matrix can comprise, water, and / or oil such as liquid paraffin and vegetable oil (such as peanut oil or castor oil), or solvent such as polyethylene glycol.The thickener and gel that use according to matrix properties comprise soft paraffin, aluminum stearate, cetearyl alcohol, polyethylene glycol, lanolin, beeswax, carboxyvinyl polyol and cellulose derivative, and / or glyceryl monostearate and / or nonionic emulsifier.

[0205] The compounds of the present invention can also be combined with soluble polymers as targetable drug carriers. Such polymers include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethylene glycol polylysine substituted with palmitoyl residues. In addition, the compounds disclosed in the present invention can be combined with a class of biodegradable polymers used in achieving controlled release of drugs, for example, cross-linked or amphiphilic block copolymers of polylactic acid, poly-ε-caprolactone, polyhydroxybutyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacrylates, and hydrogels.

These formulations can be administered by a variety of routes, including oral, buccal, rectal, intranasal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal administration. Many of the compounds used in the methods of the present invention are effective as injectable and oral compositions.

[0212] For transdermal administration, a transdermal delivery device ("patch") is needed. This transdermal patch can be used to continuously or intermittently inject a controlled amount of the compound of the present invention. The structure and application of transdermal patches for delivering drugs are well known in the art. For example, see US5,023,252. This patch can be made into a continuous, pulsatile or on-demand release drug.

[0213] The compound represented by Formula (I), (II), (III), (IV) or (V) or a pharmaceutically acceptable salt thereof is typically administered orally in the form of a pharmaceutical formulation comprising the active ingredient or a pharmaceutically acceptable salt or solvate thereof, or a solvate of a pharmaceutically acceptable salt, in a pharmaceutically acceptable dosage form. The pharmaceutical formulation administered depends on the disease to be treated and the patient, and the pharmaceutical composition can be administered at different doses.

[0214] The pharmaceutical preparations described above having a compound represented by formula (I), (II), (III), (IV) or (V) can be prepared for oral administration, specifically in the form of tablets or capsules, and particularly relate to a technique aimed at providing colon-targeted drug release (Patel, MM Expert Opin. Drug Deliv. [Expert Opinion on Drug Delivery] 2011, 8(10), 1247-1258).

[0215] The pharmaceutical formulations of the compounds of Formula (I), (II), (III), (IV) or (V) described above are conveniently administered in unit dosage form and can be prepared by any of the methods well known in the pharmaceutical art, for example, as described in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, PA. (1985). The term "unit dosage form" refers to physically discrete units suitable as unit dosages for human patients and other mammals, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutically acceptable excipient as described above.

[0216] Pharmaceutical preparations suitable for oral administration can include one or more physiologically compatible carriers and / or excipients and can be in the form of solid or liquid. Tablets and capsules can be prepared with fillers, binders, lubricants and / or surfactants (such as sodium lauryl sulfate). Liquid compositions can contain conventional additives such as emulsifiers, suspending agents and / or preservatives. Liquid compositions can be encapsulated in, for example, gelatin to provide unit dosage forms. Solid oral dosage forms include tablets, two-stage hard shell capsules and soft elastic gelatin (SEG) capsules. Such two-stage hard shell capsules can be prepared, for example, by filling a compound shown in formula (I), (II), (III), (IV) or (V) into hydroxypropyl methylcellulose (HPMC) or a gelatin shell.

[0217] The dry shell formulation typically comprises gelatin at a concentration of about 40% to 60% w / w, water at a concentration of about 30% to 40%, and a plasticizer (such as glycerol, propylene glycol, or sorbitol) at a concentration of about 20% to 30%. Other materials such as dyes, flavorings, preservatives, and opacifiers may also be present. The liquid filler material comprises a solid drug that has been dissolved, solubilized, or dispersed (using a suspending agent such as polyethylene glycol 4000, hydrogenated castor oil, or beeswax) or a liquid drug in a combination of a vehicle or multiple vehicles such as glycols, polyols, vegetable oils, mineral oils, triglycerides, and surfactants.

[0218] As used herein, the term "therapeutically effective amount" refers to the total amount of each active ingredient sufficient to exhibit a beneficial therapeutic effect. For example, an amount sufficient to treat, cure, or alleviate the symptoms of a disease when administered or brought into equilibrium in the body. The effective amount required for a particular treatment regimen depends on a variety of factors, including the disease being treated, the severity of the disease, the activity of the specific drug being used, the route of administration, the clearance rate of the specific drug, the duration of treatment, the use of concomitant medications, the age, weight, sex, diet, and health of the patient. A description of other factors that need to be considered in the art regarding a "therapeutically effective amount" can be found in Gilman et al., eds., Goodman And Gilman's: The Pharmacological Bases of Therapeutics, 8 th ed., Pergamon Press, 1990; Remington's Pharmaceutical Sciences, 17 th ed., Mack Publishing Company, Easton, Pa., 1990.

[0219] Oral formulations are preferred, particularly tablets or capsules, which can be formulated by methods known to those skilled in the art to provide a dose in the range of 0.1 mg to 1000 mg of active compound.

[0220] In the treatment of humans, a suitable daily dose of a compound shown in formula (I), (II), (III), (IV) or (V) or a pharmaceutically acceptable salt thereof is about 0.0001 to 100 mg / kg body weight. However, it should be understood that the amount of compound actually administered will be determined by the attending physician according to relevant circumstances, including the disease being treated, the selected route of administration, the actual one or more compounds to be taken, the age, body weight and response of the specific patient, and the severity of the patient's symptoms. Therefore, the above dosage range should not limit the scope of the invention in any way. In some cases, a dosage level lower than the lower limit of the above dosage range may be more appropriate, while in other cases, a higher dosage that does not produce any side effects can be adopted, provided that this larger dose is first divided into several smaller doses for administration throughout the day.

[0221] The term "administration" refers to providing a therapeutically effective amount of a drug to an individual, and administration routes include oral, sublingual, intravenous, subcutaneous, transdermal, intramuscular, intradermal, intrathecal, epidural, intraocular, intracranial, inhalation, rectal, vaginal, and the like. Dosage forms include ointments, lotions, tablets, capsules, pills, dispersible powders, granules, suppositories, pills, lozenges, injections, sterile solutions or non-aqueous solutions, suspensions, emulsions, patches, and the like. The active ingredient is compounded with a non-toxic pharmaceutically acceptable carrier (e.g., glucose, lactose, gum arabic, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, silica gel, potato starch, urea, dextran, and the like).

[0222] The preferred route of administration will vary depending on clinical circumstances, and dosage must be adjusted based on the patient being treated. The physician will determine the appropriate dosage for each individual patient. The therapeutically effective amount per unit dose depends on body weight, physiology, and the chosen vaccination regimen. The compound per unit dose refers to the weight of the compound per administration, excluding the weight of the vehicle (which is present in the drug).

[0223] The pharmaceutical compositions provided herein can be formulated for single or multiple dose administration. The single dose formulations are packaged in ampoules, vials, or syringes. The multiple dose parenteral formulations must contain an antimicrobial agent at a bacteriostatic or fungistatic concentration. All parenteral formulations must be sterile, as known and practiced in the art.

[0224] The pharmaceutical composition provided by the present invention can be co-formulated with other active ingredients that do not impair the intended therapeutic effect, or co-formulated with substances that supplement the intended effect.

[0225] In one embodiment, the treatment methods of the present invention comprise administering to a patient in need thereof a safe and effective amount of a compound of the present invention or a pharmaceutical composition comprising the compound of the present invention. Various embodiments of the present invention include treating the diseases mentioned herein by administering to a patient in need thereof a safe and effective amount of a compound of the present invention or a pharmaceutical composition comprising the compound of the present invention.

[0226] In one embodiment, the compounds of the present invention or pharmaceutical compositions comprising the compounds of the present invention can be administered by any suitable route of administration, including systemic administration and topical administration. Systemic administration includes oral administration, parenteral administration, transdermal administration, and rectal administration. Typical parenteral administration refers to administration by injection or infusion, including intravenous, intramuscular, and subcutaneous injection or infusion. Topical administration includes application to the skin, as well as intraocular, ear, vaginal, inhalation, and intranasal administration. In one embodiment, the compounds of the present invention or pharmaceutical compositions comprising the compounds of the present invention can be administered orally. In another embodiment, the compounds of the present invention or pharmaceutical compositions comprising the compounds of the present invention can be administered by inhalation. In another embodiment, the compounds of the present invention or pharmaceutical compositions comprising the compounds of the present invention can be administered intranasally.

[0227] In one embodiment, the compound of the present invention or a pharmaceutical composition comprising the compound of the present invention can be administered once or several times at different time intervals within a specified time period according to a dosing regimen. For example, the drug is administered once, twice, three times, or four times a day. In one embodiment, the drug is administered once a day. In another embodiment, the drug is administered twice a day. The drug can be administered until the desired therapeutic effect is achieved or the desired therapeutic effect is maintained indefinitely. The appropriate dosing regimen for the compound of the present invention or a pharmaceutical composition comprising the compound of the present invention depends on the pharmacokinetic properties of the compound, such as absorption, distribution, and half-life, which can be determined by a skilled person. In addition, the appropriate dosing regimen for the compound of the present invention or a pharmaceutical composition comprising the compound of the present invention, including the duration of implementation of the regimen, depends on the disease being treated, the severity of the disease being treated, the age and physical condition of the patient being treated, the medical history of the patient being treated, the nature of the concurrent therapy, the desired therapeutic effect, and other factors within the knowledge and experience of the skilled person. Such skilled persons should also understand that the appropriate dosing regimen may be required to be adjusted for individual patients' responses to the dosing regimen or as individual patient needs change over time.

[0228] The compounds of the present invention can be administered simultaneously with, before, or after one or more other therapeutic agents. The compounds of the present invention can be administered separately with other therapeutic agents by the same or different routes of administration, or can be administered with them in the form of the same pharmaceutical composition. This is selected by those skilled in the art based on the actual physical conditions of the patient, such as health, age, weight, etc. If formulated as a fixed dose, such a combination product uses a compound of the present invention (within the dosage range described herein) and other pharmaceutically active agents (within their dosage range).

[0229] Accordingly, in one aspect, the present invention encompasses a combination comprising a quantity of at least one compound of the present invention, or a pharmaceutically acceptable salt, solvate, ester or prodrug thereof, and an effective amount of one or more additional therapeutic agents as described above.

[0230] In addition, the compounds of the present invention can be administered in the form of prodrugs. In the present invention, a "prodrug" of a compound of the present invention is a functional derivative that, when administered to a patient, ultimately releases the compound of the present invention in vivo. When administering the compound of the present invention in the form of a prodrug, one skilled in the art may implement one or more of the following methods: (a) altering the onset of action of the compound in vivo; (b) altering the duration of action of the compound in vivo; (c) altering the transport or distribution of the compound in vivo; (d) altering the solubility of the compound in vivo; and (e) overcoming the side effects or other difficulties faced by the compound. Typical functional derivatives used to prepare prodrugs include variants of the compound that are chemically or enzymatically cleaved in vivo. These variants, including those for preparing phosphates, amides, esters, thioesters, carbonates, and carbamates, are well known to those skilled in the art.
