HETEROBIFUNCTIONAL COMPOUNDS AND METHODS OF TREATING DISEASE CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of and priority to United States Provisional Patent Application serial number 63/404,575, filed September 8, 2022, and United States Provisional Patent Application serial number 63/506,790, filed June 7, 2023; the contents of each of which are hereby incorporated by reference in their entirety. FIELD OF THE INVENTION [0002] The invention provides heterobifunctional compounds, pharmaceutical compositions, and their use in treating disease, such as cancer. BACKGROUND [0003] Cancer continues to be a significant health problem despite the substantial research efforts and scientific advances reported in the literature for treating this disease. Solid tumors, including prostate cancer, breast cancer, and lung cancer remain highly prevalent among the world population. The incidence of prostate cancer increases with age, and with increasing longevity of human subjects, there continues to be a corresponding rise in the number of patients suffering from prostate cancer. Breast cancer is one of the most common cancers among women and is a leading cause of death for women between ages 50-55. Lung cancer is a leading cause of death among cancer patients, where over 85% of lung cancers are non-small cell lung cancer (NSCLC). Many lung cancers are attributed to tobacco smoking. Current treatment options for these cancers are not effective for all patients and/or can have substantial adverse side effects. [0004] New therapies are needed to address this unmet need in cancer therapy. In particular, new therapies are needed that achieve an anti-cancer effect through a different mechanism than commonly available therapies. Exemplary mechanisms for common anti-cancer therapies include (a) alkylation of DNA which limits ability of the cell to reproduce, (b) topoisomerase inhibition, in which the therapeutic agent inhibits the activity of a topoisomerases thereby limiting separation of strands of DNA, and (c) mitotic inhibition, where the therapeutic agent reduces ability of the cell to divide. New therapies that achieve an anti-cancer effect through a different mechanism present an opportunity to treat cancers more effectively and/or to treat cancers that have become resistant to currently available medicines. [0005] The present invention addresses the foregoing needs and provides other related advantages. SUMMARY [0006] The invention provides heterobifunctional compounds, pharmaceutical compositions, and their use in treating disease, such as cancer.

[0013] Various aspects of the invention are set forth below in sections; however, aspects of the invention described in one particular section are not to be limited to any particular section. Further, when a variable is not accompanied by a definition, the previous definition of the variable controls. Definitions [0014] Compounds of the present invention include those described generally herein, and are further illustrated by the classes, subclasses, and species disclosed herein. As used herein, the following definitions shall apply unless otherwise indicated. These definitions apply regardless of whether a term is used by itself or in combination with other terms, unless otherwise indicated.

[0040] Further, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are discussed, for example, by P. Stahl et al., Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use. (2002) Zurich: Wiley-VCH; S. Berge et al., Journal of Pharmaceutical Sciences (1977) 66(1) 1-19; P. Gould, International J. of Pharmaceutics (1986) 33201-217; Anderson et al., The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (Food & Drug Administration, Washington, D.C. on their website). These disclosures are incorporated herein by reference. [0041] Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N ⁺ (C _1–4 alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate. [0042] Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. The invention includes compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a ¹³ C- or ¹⁴ C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. [0043] Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher’s acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Alternatively, a particular enantiomer of a compound of the present invention may be prepared by asymmetric synthesis. Still further, where the molecule contains a basic functional group (such as amino) or an acidic functional group (such as carboxylic acid) diastereomeric salts are formed with an appropriate optically- active acid or base, followed by resolution of the diastereomers thus formed by fractional crystallization or chromatographic means known in the art, and subsequent recovery of the pure enantiomers. [0044] Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers.

TABLE 1

Synthetic Methods [0386] Methods for preparing compounds described herein are illustrated in the following synthetic Schemes. The Schemes are given for the purpose of illustrating the invention, and are not intended to limit the scope or spirit of the invention. Starting materials shown in the Schemes can be obtained from commercial sources or can be prepared based on procedures described in the literature. [0387] In the Schemes, it is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule should be compatible with the reagents and reactions proposed. Substituents not compatible with the reaction conditions will be apparent to one skilled in the art, and alternate methods are therefore indicated (for example, use of protecting groups or alternative reactions). Protecting group chemistry and strategy is well known, such as described in, for example, “Protecting Groups in Organic Synthesis”, T. W. Greene and P. G. M. Wuts, 3 ^rd edition, John Wiley & Sons, 1999, the entire contents of which are hereby incorporated by reference. [0388] The synthetic route illustrated in Scheme 1 is a general method for preparing compounds of Formula H. Coupling fluoro-nitrobenzene compound A with substituted phenol B provides phenyl ether compound C. Reduction of the nitro group in compound C provides substituted aniline D. Reaction of substituted aniline D with ClSO ₂ R ⁱ provides sulfonamide E. Removal of the protection group (Pg) from compound E provides compound F. The Pg may be, for example, a Boc protecting group that can be removed by treating the compound with trifluoroacetic acid. Coupling compound F with compound G (such as a nucleophilic aromatic substitution reaction when X is an amino group and the leaving group in compound E is chloro) provides the final compound of Formula H.

SCHEME 1. [0389] The modular synthetic route illustrated in Scheme 1 can be readily modified to provide additional compounds by conducting functional group transformations on the intermediate and/or final compounds. Such functional group transformations are well known in the art, as described in, for example, Comprehensive Organic Synthesis (B.M. Trost & I. Fleming, eds., 1991-1992); Organic Synthesis, 3 ^rd Ed. (Michael B. Smith, Wavefunction, Inc., Irvine: 2010); Modern Methods of Organic Synthesis, 4 ^th Ed. (William Carruthers and Iain Coldham, Cambridge University Press, Cambridge: 2004); March’s Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 8 ^th Ed., (Michael B. Smith, John Wiley & Sons, New York: 2020); and Comprehensive Organic Transformations: A Guide to Functional Group Preparations, 3rd Ed. (Richard C. Larock, ed., John Wiley & Sons, New York: 2018). Protecting group strategies may be deployed as appropriate to accommodate differing functional groups in the molecules used in the synthetic route. Protecting group chemistry and strategy is described in, for example, Protecting Groups in Organic Synthesis, 3 ^rd Edition, T. W. Greene and P. G. M. Wuts, John Wiley & Sons, 1999 and Greene's Protective Groups in Organic Synthesis, 5th Ed., (Peter G. M. Wuts, John Wiley & Sons: 2014). II.

[0438] Another aspect of the invention provides for the use of a compound described herein (such as a compound of Formula I, Formula II, or other compounds in Section I) for treating a medical disease, such a disease described herein (e.g., cancer). Evaluation of Cellular Growth Inhibition of HEK293 cells and HeLa cells [0439] Compounds can be evaluated for ability to inhibit the proliferation of HEK293 cells or HeLa cells according to the following procedure. HEK293 and HeLa cells are cultured in DMEM medium supplemented with 10% fetal bovine serum and 1% Penn/Strep. Cells are seeded in white 384-well plates at 500 cells/well in 25 ^L complete medium. Following seeding, plates are spun at 300 × g^for three minutes and cultured at 37°C with 5% CO ₂ ^in a humidified tissue culture incubator. After 24 hours, compounds are titrated in 100% DMSO and diluted in complete cell culture medium. A 25 ^L aliquot of compound/media mixture is added to cells to bring total volume in well to 50 ^L. DMSO alone is used as a negative control. Plates are then spun at 300×g^for three minutes and stored at 37°C with 5% CO2 for three days. On Day 0 and Day 3 of compound treatment, cell viability is quantified with CellTiter-Glo 2.0 reagent (Promega). After equilibrating microplates at room temperature for 30 minutes, 25 µL CellTiter- Glo 2.0 reagent is dispensed into each well to bring total volume to 75 ^L. Plates are mixed on shaker for 2 minutes at 500rpm, followed by a 10-minute incubation at room temperature. Following a quick spin, luminescence readings are measured with an EnVision Plate Reader. Data is normalized to DMSO treated Day 0 and Day 3 readings. A four-parameter non-linear regression curve fit is applied to dose-response data in GraphPad Prism data analysis software to determine the half maximal growth inhibitory concentration (GI ₅₀ ) for each compound. III. Pharmaceutical Compositions and Dosing Considerations [0440] As indicated above, the invention provides pharmaceutical compositions, which comprise a therapeutically-effective amount of one or more of the compounds described above, formulated together with one or more pharmaceutically acceptable carriers (additives) and/or diluents. The pharmaceutical compositions may be specially formulated for administration in solid or liquid form, including those adapted for the following: (1) oral administration, for example, drenches (aqueous or non-aqueous solutions or suspensions), tablets, e.g., those targeted for buccal, sublingual, and systemic absorption, boluses, powders, granules, pastes for application to the tongue; (2) parenteral administration, for example, by subcutaneous, intramuscular, intravenous or epidural injection as, for example, a sterile solution or suspension, or sustained-release formulation; (3) topical application, for example, as a cream, ointment, or a controlled-release patch or spray applied to the skin; (4) intravaginally or intrarectally, for example, as a pessary, cream or foam; (5) sublingually; (6) ocularly; (7) transdermally; or (8) nasally. In certain embodiments, the invention provides a pharmaceutical composition comprising a compound described herein (e.g., a compound of Formula I) and a pharmaceutically acceptable carrier. [0441] The phrase “therapeutically effective amount” as used herein means that amount of a compound, material, or composition comprising a compound of the present invention which is effective for producing some desired therapeutic effect in at least a sub-population of cells in an animal at a reasonable benefit/risk ratio applicable to any medical treatment. [0442] The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. [0443] Wetting agents, emulsifiers and lubricants, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, release agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the compositions. [0444] Examples of pharmaceutically-acceptable antioxidants include: (1) water soluble antioxidants, such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite and the like; (2) oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, alpha-tocopherol, and the like; and (3) metal chelating agents, such as citric acid, ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like. [0445] Formulations of the present invention include those suitable for oral, nasal, topical (including buccal and sublingual), rectal, vaginal and/or parenteral administration. The formulations may conveniently be presented in unit dosage form and may be prepared by any methods well known in the art of pharmacy. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will vary depending upon the host being treated, the particular mode of administration. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect. Generally, out of one hundred percent, this amount will range from about 0.1 percent to about ninety-nine percent of active ingredient, preferably from about 5 percent to about 70 percent, most preferably from about 10 percent to about 30 percent. [0446] In certain embodiments, a formulation of the present invention comprises an excipient selected from the group consisting of cyclodextrins, celluloses, liposomes, micelle forming agents, e.g., bile acids, and polymeric carriers, e.g., polyesters and polyanhydrides; and a compound of the present invention. In certain embodiments, an aforementioned formulation renders orally bioavailable a compound of the present invention. [0447] Methods of preparing these formulations or compositions include the step of bringing into association a compound of the present invention with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the present invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product. [0448] Formulations of the invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or a 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 pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or as mouth washes and the like, each containing a predetermined amount of a compound of the present invention as an active ingredient. A compound of the present invention may also be administered as a bolus, electuary or paste. [0449] In solid dosage forms of the invention for oral administration (capsules, tablets, pills, dragees, powders, granules, trouches and the like), 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 starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds and surfactants, such as poloxamer and sodium lauryl sulfate; (7) wetting agents, such as, for example, cetyl alcohol, glycerol monostearate, and non-ionic surfactants; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, zinc stearate, sodium stearate, stearic acid, and mixtures thereof; (10) coloring agents; and (11) controlled release agents such as crospovidone or ethyl cellulose. In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-shelled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like. [0450] A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. [0451] The tablets, and other solid dosage forms of the pharmaceutical compositions of the present invention, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art. They may also be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymer matrices, liposomes and/or microspheres. They may be formulated for rapid release, e.g., freeze-dried. They may be sterilized by, for example, filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. These compositions may also optionally contain opacifying agents and may be of a composition that they 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 which 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-described excipients. [0452] Liquid dosage forms for oral administration of the compounds of the invention include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. [0453] 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. [0454] Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof. [0455] Formulations of the pharmaceutical compositions of the invention for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more compounds of the invention with one or more suitable nonirritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or a salicylate, and which is solid at room temperature, but liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active compound. [0456] Formulations of the present invention which are suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate. [0457] Dosage forms for the topical or transdermal administration of a compound of this invention 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. [0458] The ointments, pastes, creams and gels may contain, in addition to an active compound of this invention, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof. [0459] Powders and sprays can contain, in addition to a compound of this invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane. [0460] Transdermal patches have the added advantage of providing controlled delivery of a compound of the present invention to the body. Such dosage forms can be made by dissolving or dispersing the compound in the proper 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 either providing a rate controlling membrane or dispersing the compound in a polymer matrix or gel. [0461] Ophthalmic formulations, eye ointments, powders, solutions and the like, are also contemplated as being within the scope of this invention. [0462] Pharmaceutical compositions of this invention suitable for parenteral administration comprise one or more compounds of the invention in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain sugars, alcohols, antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents. [0463] Examples of suitable aqueous and nonaqueous carriers which may be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), 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 the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. [0464] These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms upon the subject compounds may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin. [0465] In some cases, in order to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally-administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. [0466] Injectable depot forms are made by forming microencapsule matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer, and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissue. [0467] When the compounds of the present invention are administered as pharmaceuticals, to humans and animals, they can be given per se or as a pharmaceutical composition containing, for example, 0.1 to 99% (more preferably, 10 to 30%) of active ingredient in combination with a pharmaceutically acceptable carrier. [0468] The preparations of the present invention may be given orally, parenterally, topically, or rectally. They are of course given in forms suitable for each administration route. For example, they are administered in tablets or capsule form, by injection, inhalation, eye lotion, ointment, suppository, etc. administration by injection, infusion or inhalation; topical by lotion or ointment; and rectal by suppositories. Oral administrations are preferred. [0469] The phrases “parenteral administration” and “administered parenterally” as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion. [0470] The phrases “systemic administration,” “administered systemically,” “peripheral administration” and “administered peripherally” as used herein mean the administration of a compound, drug or other material other than directly into the central nervous system, such that it enters the patient’s system and, thus, is subject to metabolism and other like processes, for example, subcutaneous administration. [0471] These compounds may be administered to humans and other animals for therapy by any suitable route of administration, including orally, nasally, as by, for example, a spray, rectally, intravaginally, parenterally, intracisternally and topically, as by powders, ointments or drops, including buccally and sublingually. [0472] Regardless of the route of administration selected, the compounds of the present invention, which may be used in a suitable hydrated form, and/or the pharmaceutical compositions of the present invention, are formulated into pharmaceutically-acceptable dosage forms by conventional methods known to those of skill in the art. [0473] Actual dosage levels of the active ingredients in the pharmaceutical compositions of this invention may be varied so as to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient. [0474] The selected dosage level will depend upon a variety of factors including the activity of the particular compound of the present invention employed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion or metabolism of the particular compound being employed, the rate and extent of absorption, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular 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. [0475] A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the effective amount of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the compounds of the invention employed in the pharmaceutical composition at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved. [0476] In general, a suitable daily dose of a compound of the invention will be that amount of the compound which is the lowest dose effective to produce a therapeutic effect. Such an effective dose will generally depend upon the factors described above. Preferably, the compounds are administered at about 0.01 mg/kg to about 200 mg/kg, more preferably at about 0.1 mg/kg to about 100 mg/kg, even more preferably at about 0.5 mg/kg to about 50 mg/kg. When the compounds described herein are co-administered with another agent (e.g., as sensitizing agents), the effective amount may be less than when the agent is used alone. [0477] If desired, the effective daily dose of the active compound may be administered as two, three, four, five, six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms. Preferred dosing is one administration per day. [0478] The invention further provides a unit dosage form (such as a tablet or capsule) comprising a heterobifunctional substituted phenylpyrimidinone or related compound described herein in a therapeutically effective amount for the treatment of a medical disorder described herein. IV. MEDICAL KITS [0479] Another aspect of this invention is a kit comprising (i) a compound described herein, such as a compound of Formula I, and (ii) instructions for use, such as treating cancer. EXAMPLES [0474] The invention now being generally described will be more readily understood by reference to the following examples, which are included merely for purposes of illustration of certain aspects and embodiments of the present invention, and are not intended to limit the invention.

Experimental procedures and results are provided below. Part I – Experimental Procedure [0947] Compounds were tested using a bromoKdELECT assay. T7 phage strains displaying bromodomains were grown in parallel in 24-well blocks in an E. coli host derived from the BL21 strain. E. coli were grown to log-phase and infected with T7 phage from a frozen stock (multiplicity of infection = 0.4) and incubated with shaking at 32°C until lysis (90-150 minutes). The lysates were centrifuged (5,000 x g) and filtered (0.2μm) to remove cell debris. Streptavidin-coated magnetic beads were treated with biotinylated small molecule or acetylated peptide ligands for 30 minutes at room temperature to generate affinity resins for bromodomain assays. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligand and to reduce nonspecific phage binding. Binding reactions were assembled by combining bromodomains, liganded affinity beads, and test compounds in 1x binding buffer (17% SeaBlock, 0.33x PBS, 0.04% Tween 20, 0.02% BSA, 0.004% Sodium azide, 7.4 mM DTT). Test compounds were prepared as 1000X stocks in 100% DMSO. Kds were determined using an 11-point 3-fold compound dilution series with one DMSO control point. All compounds for Kd measurements are distributed by acoustic transfer (non-contact dispensing) in 100% DMSO. The compounds were then diluted directly into the assays such that the final concentration of DMSO was 0.09%. All reactions performed in polypropylene 384-well plates. Each was a final volume of 0.02 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer (1x PBS, 0.05% Tween 20). The beads were then resuspended in elution buffer (1x PBS, 0.05% Tween 20, 2 μM non-biotinylated affinity ligand) and incubated at room temperature with shaking for 30 minutes.

Experimental procedures and results are provided below. Part I – Experimental Procedure [0953] The following types of cells were prepared for this experiment: (i) a T-Rex 293 cell line having increased expression of androgen receptor protein due to exposure to doxycycline and (ii) a T-Rex 293 cell line lacking increased expression of androgen receptor protein. Ability of the test compounds to inhibit proliferation of the foregoing cell types was evaluated according to the procedures set forth below.

Transfected cells were selected using 400 µg/mL Zeocin (Invitrogen Cat#R25001). Following selection, single clones were raised and maintained in Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% w/w Tetracycline-free fetal bovine serum (FBS) and 250 µg/mL Zeocin. Clones were analyzed for expression of androgen receptor protein in the presence and absence of 10 ng/mL doxycycline (Sigma Cat#D9891), and a single doxycycline- inducible clone (hereinafter “SC3”) was selected for use in downstream assays. [0955] The SC3 cells were seeded on poly-D-lysine coated, black clear-bottom 384- well plates at 2500/well, in 25 ^L Phenol Red Free Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% w/w charcoal-dextran treated fetal bovine serum (FBS) and 1% w/w pen-strep, with or without 10 ng/mL doxycycline.

Following treatment of cells with Test Compound Solution or said equal volume of a solution containing DMSO and Treatment Medium, the plates were spun at 300 × g for 30 seconds, and then left in an incubator for 72 hours. [0957] At the end of the treatment duration, cell viability was quantified with CellTiter- Glo 2.0 reagent (Promega Cat#G9243). For this purpose, plates were equilibrated to room temperature for 30 minutes, and then 25 µL of CellTiter-Glo 2.0 reagent was added to cells in the plate wells. Plates were then agitated on a shaker for two minutes at 500 rpm and subsequently incubated at room temperature for 10 minutes. Following incubation, the plates were spun at 3000 x g for 30 seconds, then sealed with an optical adhesive cover, and luminescence readings were measured with an EnVision Plate Reader. [0958] Data was normalized using zero luminescence for baseline. A four-parameter non- linear regression curve fit was applied to dose-response data in GraphPad Prism data analysis software to determine the half-maximal growth inhibitory concentration (GI50) for each test compound.

EXAMPLE 73 – Cellular Growth Inhibition Assay for T47D Cells [0976] Exemplary compounds were tested for ability to inhibit the proliferation of T47D cells. T47D cells are a commercially available human breast cancer cell line. Experimental procedures and results are provided below. Part I – Experimental Procedure [0977] T47D cells were purchased from American Type Cell Culture (ATCC Cat# HTB- 133) and then seeded on poly-D-lysine coated, black clear-bottom 384-well plates at 3000/well in 25 ^L Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% w/w Fetal bovine serum (FBS), 0.2 units/mL recombinant human insulin (Gibco Cat# 12585014), and 1% w/w Pen-Strep. Pen-Strep is a commercially available mixture of penicillin G and streptomycin, which is used in mammalian cell culture media to prevent bacterial contamination. Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% w/w fetal bovine serum (FBS), 0.2 units/mL recombinant human insulin, and 1% w/w Pen-Strep is herein referred to as Treatment Medium. Following seeding of cells in the plates, the plates were spun at 300 × g^for 30 seconds, then equilibrated to room temperature for 30 minutes, and then deposited^in a humidified tissue culture incubator maintained at 37 °C with 5% CO ₂ . [0978] At 24 hours after seeding of the cells, dilutions of test compound were prepared in DMSO and dissolved in Treatment Medium, to achieve a final DMSO concentration of 0.5% w/w, thereby providing the Test Compound Solution. A 25 ^L aliquot of the Test Compound Solution was added to cells in the well plates. An equal volume of a solution containing DMSO and Treatment Medium was used as a negative control. Following treatment of cells with Test Compound Solution or said equal volume of a solution containing DMSO and Treatment Medium, the plates were spun at 300 × g for 30 seconds, and then left in an incubator for 72 hours. [0979] At the end of the treatment duration, cell viability was quantified with CellTiter- Glo 2.0 reagent (Promega Cat#G9243). For this purpose, plates were equilibrated to room temperature for 30 minutes, and then 25 µL of CellTiter-Glo 2.0 reagent was added to cells in the plate wells. Plates were then agitated on a shaker for two minutes at 500 rpm and subsequently incubated at room temperature for 10 minutes. Following incubation, the plates were spun at 3000 x g for 30 seconds, then sealed with an optical adhesive cover, and luminescence readings were measured with an EnVision Plate Reader (Perkin Elmer). [0980] Data was normalized using zero luminescence for baseline. A four-parameter non- linear regression curve fit was applied to dose-response data in GraphPad Prism data analysis software to determine the half-maximal growth inhibitory concentration (GI50) for each test compound. Part II – Results [0981] The half-maximal growth inhibitory concentration (GI50) results are provided in Table 13 below for exemplary compounds. The symbol “++++” indicates a GI50 less than 0.5 ^M. The symbol “+++” indicates an GI ₅₀ in the range of 0.5 ^M to 1.5 ^M. The symbol “++” indicates a GI ₅₀ in the range of greater than 1.5 ^M to 3 ^M. The symbol “+” indicates a GI ₅₀ greater than 3 ^M. The symbol “N/A” indicates that no data was available. TABLE 13.

EXAMPLE 74 – Assay for Binding Affinity to Progesterone Receptor [0982] Exemplary compounds were tested for ability to bind to the progesterone receptor. Experimental procedures and results are provided below. Part I – Experimental Procedure [0983] Compounds were tested using the PR Human Progesterone NHR Binding (Agonist Radioligand) Assay, Cerep at Eurofins Discovery using a modified version of the protocol from Sarup et al. (Cancer Res 1988;48:5071-5078). Briefly, cytosolic fractions of T47D cells were incubated with 0.5 nM [ ³ H]progesterone for 1 hour at 4°C in the absence or presence of the test compound. Nonspecific binding was determined in the presence of 1 μM promegestone. Reactions were subjected to scintillation counting. Results are expressed as a percent inhibition of the control radioligand specific binding. Part II – Results [0984] Results showing ability of exemplary compounds to bind to the progesterone receptor are provided in Table 14 below. The symbol “++++” indicates a Ki less than 0.05 ^M. The symbol “+++” indicates an Ki in the range of 0.05 ^M to 0.5 ^M. The symbol “++” indicates a Ki in the range of greater than 0.5 ^M to 2.5 ^M. The symbol “+” indicates a Ki greater than 2.5 ^M. The symbol “N/A” indicates that no data was available. TABLE 14. EXAMPLE 75 – FP Assay for Binding Affinity to Progesterone Receptor [0985] Exemplary compounds were tested for ability to bind to the progesterone receptor ligand binding domain (LBD). Experimental procedures and results are provided below. Part I – Experimental Procedure [0986] Compounds were tested using the PolarScreen™ Progesterone Receptor Competitor Assay Kit (Life Technologies Cat# A15905 or a15906), as per the manufacturer’s instructions. Briefly, GST-tagged PR LBD, Fluormone tracer, and compound were mixed and incubated for 2 hours at room temperature in the dark. Following incubation, the plates were spun at 3000 x g for 30 seconds, then sealed with an optical adhesive cover, and fluorescence polarization was measured using appropriate excitation and emission filters with an EnVision Plate Reader (Perkin Elmer). Compound concentration vs. mP value were plotted in Prism (GraphPad). A four-parameter non-linear regression curve fit was applied to dose- response data to determine the half-maximal inhibitory concentration (IC ₅₀ ) for each test compound. Part II – Results [0987] The half-maximal inhibitory concentration (IC ₅₀ ) results are provided in Table 15 below for exemplary compounds. The symbol “++++” indicates a IC ₅₀ less than 0.05 ^M. The symbol “+++” indicates an IC ₅₀ in the range of 0.05 ^M to 0.5 ^M. The symbol “++” indicates a IC ₅₀ in the range of greater than 0.5 ^M to 2.5 ^M. The symbol “+” indicates a IC ₅₀ greater than 2.5 ^M. The symbol “N/A” indicates that no data was available.
