Proteins of the bromodomain and extra-terminal domain (BET) family are epigenetic readers that bind acetylated histones through their bromodomains to regulate gene transcription. As gene regulation is an important function to modulate for treatment of diseases such as cancer, the BET family proteins have received considerable attention as targets for drug discovery. BET proteins bind to acetylated histones through their tandem bromodomains, BDI and BDII. Pan-BET inhibitors that bind with similar affinities to the BDI and BDII bromodomains of BRD2, BRD3, BRD4 and BRDt have shown modest clinical activity in monotherapy cancer trials. Many pan-BET inhibitors are associated with dose-limiting adverse events, such as thrombocytopenia and signs of gastrointestinal toxicity.1-5 These adverse events may represent on-target activities associated with pan-BET inhibition. The individual BET bromodomains may have distinct functions7-9, and different cellular phenotypes after pharmacological inhibition of one or both bromodomains have been reported.10-11 This observation suggests that selectively targeting one of the bromodomains may result in a different efficacy and tolerability profile compared with a pan-BET inhibitor. There remains a need to develop BET inhibitors that are selective for the BDII bromodomain. Such a selective inhibitor may maintain the therapeutic efficacy associated with a pan-BET inhibitor, while minimizing on-target adverse effects.

Alternatively, where the molecule contains a basic functional group, such as amino, or an acidic functional group, such as carboxyl, 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 well known in the art, and subsequent recovery of the pure enantiomers.
It will be understood that “substitution” or “substituted with” includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., which does not spontaneously undergo transformation such as by rearrangement, fragmentation, decomposition, cyclization, elimination, or other reaction.
The term “substituted” is also contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, those described herein above. The permissible substituents may be one or more and the same or different for appropriate organic compounds. For purposes of this invention, the heteroatoms such as nitrogen may have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. This invention is not intended to be limited in any manner by the permissible substituents of organic compounds.
“Substituted with deuterium” refers to the replacement of one or more hydrogen atoms with a corresponding number of deuterium atoms.
In certain embodiments, a compound of the invention is substituted by deuterium. For example, in an alkyl group, one or more hydrogen atoms may be replaced by a corresponding number of deuterium atoms.
It will be recognized that some variation of natural isotopic abundance occurs in a synthesized compound depending upon the origin of chemical materials used in the synthesis. Thus, a preparation of a compound of the invention will inherently contain small amounts of deuterated isotopologues. The concentration of naturally abundant stable hydrogen and carbon isotopes, notwithstanding this variation, is small and immaterial as compared to the degree of stable isotopic substitution of the deuterated compounds of this invention. See, for instance, Wada, E et al., Seikagaku, 1994, 66: 15; Gannes, L Z et al., Comp Biochem Physiol Mol Integr Physiol, 1998, 119:725.
In the compounds of this invention any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. The stable isotopes of hydrogen are 1H (protium) and 2H (deuterium). Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at its natural abundance isotopic composition. Also unless otherwise stated, when a position is designated specifically as “D” or “deuterium”, the position is understood to have deuterium at an abundance that is at least 3340 times greater than the natural abundance of deuterium, which is 0.015% (i.e., at least 50.1% incorporation of deuterium).

In certain embodiments, the pharmaceutical composition comprises a compound of the invention and a pharmaceutically acceptable carrier. In certain embodiments, the pharmaceutical composition comprises a plurality of compounds of the invention, or pharmaceutically acceptable salts thereof, and a pharmaceutically acceptable carrier.

Methods of Use
The present invention provides compounds, and pharmaceutically acceptable salts thereof, that are useful for treating or preventing a disease or condition whose treatment would benefit from BDII-selective inhibition.
Bromodomain and extra-terminal domain (BET) family proteins regulate gene transcription through their interaction with specific acetylated lysines in the tails of histones H3 and H4. At these sites, these BET proteins recruit key components of the transcriptional machinery, thereby enabling them to control a host of gene expression programs central to diseases such as cancer. These BET proteins bind to acetylated histone tails through their two tandem bromodomains, BDI and BDII. Unfortunately, pan-BET inhibitors have exhibited on-target toxicities, such as thrombocytopenia, anemia, neutropenia, and severe gastrointestinal events. Selective inhibition of the BDII bromodomain, however, provides therapeutic efficacy while minimizing undesired toxicities.
The compounds of the invention inhibit the binding of the second bromodomains (BDII) of BRD2, BRD3, BRD4, and BRDt to their cellular targets. This function effectively alters the expression of genes essential for the growth of certain cancers, such as acute myeloid leukemia and prostate cancer.

Formulations, Routes of Administration, and Dosing
The compounds of the invention, and pharmaceutically acceptable salts thereof, can be formulated as pharmaceutical compositions and administered to a mammalian host, such as a human patient, in a variety of forms adapted to the chosen route of administration, e.g., orally or parenterally, by intravenous, intraperitoneal, intramuscular, topical, or subcutaneous routes. Additional routes of administration are also contemplated by the invention.
Thus, the present compounds or pharmaceutically acceptable salts thereof may be systemically administered, e.g., orally, in combination with a pharmaceutically acceptable vehicle such as an inert diluent or an assimilable edible carrier. They may be enclosed in hard or soft shell gelatin capsules, may be compressed into tablets, or may be incorporated directly with the food of the patient's diet. For oral therapeutic administration, the active compound (i.e., a compound of the invention or a pharmaceutically acceptable salt thereof) may be combined with one or more excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. Such compositions and preparations should contain at least 0.1% of active compound. The percentage of the compositions and preparations may, of course, be varied and may conveniently be between about 2% to about 60% of the weight of a given unit dosage form. The amount of active compound in such therapeutically useful compositions is such that an effective dosage level will be obtained.
The tablets, troches, pills, capsules, and the like may also contain the following diluents and carriers: binders such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid and the like; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, fructose, lactose or aspartame or a flavoring agent such as peppermint, oil of wintergreen, or cherry flavoring may be added. When the unit dosage form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier, such as a vegetable oil or a polyethylene glycol. Various other materials may be present as coatings or to otherwise modify the physical form of the solid unit dosage form. For instance, tablets, pills, or capsules may be coated with gelatin, wax, shellac or sugar and the like. A syrup or elixir may contain the active compound, sucrose or fructose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. Of course, any material used in preparing any unit dosage form should be pharmaceutically acceptable and substantially non-toxic in the amounts employed. In addition, the active compound may be incorporated into sustained-release preparations and devices.
The active compound may also be administered intravenously or intraperitoneally by infusion or injection. Solutions of the active compound can be prepared in water or physiologically acceptable aqueous solution, optionally mixed with a nontoxic surfactant. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, triacetin, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
The pharmaceutical dosage forms suitable for injection or infusion can include sterile aqueous solutions or dispersions or sterile powders comprising the active compound which are adapted for the extemporaneous preparation of sterile injectable or infusible solutions or dispersions, optionally encapsulated in liposomes. In all cases, the ultimate dosage form should be sterile, fluid and stable under the conditions of manufacture and storage. The liquid carrier or vehicle can be a solvent or liquid dispersion medium comprising, for example, water, ethanol, a polyol (for example, glycerol, propylene glycol, liquid polyethylene glycols, and the like), vegetable oils, nontoxic glyceryl esters, and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the formation of liposomes, by the maintenance of the required particle size in the case of dispersions or by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, buffers or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.
Sterile injectable solutions are prepared by incorporating the active compound in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filter sterilization. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation can include vacuum drying and the freeze drying techniques, which yield a powder of the active compound plus any additional desired ingredient present in the previously sterile-filtered solutions.
For topical administration, the present compounds or pharmaceutically acceptable salts thereof may be applied in pure form, i.e., when they are liquids. However, it will generally be desirable to administer them to the skin as compositions or formulations, in combination with a dermatologically acceptable carrier, which may be a solid or a liquid.
Useful solid carriers include finely divided solids such as talc, clay, microcrystalline cellulose, silica, alumina and the like. Useful liquid carriers include water, alcohols or glycols or water-alcohol/glycol blends, in which the present compounds or pharmaceutically acceptable salts thereof can be dissolved or dispersed at effective levels, optionally with the aid of non-toxic surfactants. Adjuvants such as fragrances and additional antimicrobial agents can be added to optimize the properties for a given use. The resultant liquid compositions can be applied from absorbent pads, used to impregnate bandages and other dressings, or sprayed onto the affected area using pump-type or aerosol sprayers.
Thickeners such as synthetic polymers, fatty acids, fatty acid salts and esters, fatty alcohols, modified celluloses or modified mineral materials can also be employed with liquid carriers to form spreadable pastes, gels, ointments, soaps, and the like, for application directly to the skin of the user.
Examples of useful dermatological compositions which can be used to deliver the compounds of the invention, or pharmaceutically acceptable salts thereof, to the skin are known in the art; for example, see Jacquet et al.

In certain embodiments, a compound of the invention, or pharmaceutically acceptable salt thereof, is formulated for intraocular administration, for example direct injection or insertion within or in association with an intraocular medical device.
The compounds of the invention, or pharmaceutically acceptable salts thereof, may be formulated for depositing into a medical device, which may include any of a variety of conventional grafts, stents, including stent grafts, catheters, balloons, baskets, or other device that can be deployed or permanently implanted within a body lumen. As a particular example, it would be desirable to have devices and methods which can deliver compounds of the invention, or pharmaceutically acceptable salts thereof, to the region of a body which has been treated by interventional technique.
In exemplary embodiments, a compound of the invention, or pharmaceutically acceptable salt thereof, may be deposited within a medical device, such as a stent, and delivered to the treatment site for treatment of a portion of the body.
Stents have been used as delivery vehicles for therapeutic agents (i.e., drugs). Intravascular stents are generally permanently implanted in coronary or peripheral vessels. Stent designs include those of U.S. Pat. No. 4,733,655 (Palmaz), U.S. Pat. No. 4,800,882 (Gianturco), or U.S. Pat. No. 4,886,062 (Wiktor). Such designs include both metal and polymeric stents, as well as self-expanding and balloon-expandable stents. Stents may also be used to deliver a drug at the site of contact with the vasculature, as disclosed in U.S. Pat. No. 5,102,417 (Palmaz), U.S. Pat. No. 5,419,760 (Narciso, Jr.), U.S. Pat. No. 5,429,634 (Narciso, Jr.), and in International Patent Application Nos. WO 91/12779 (Medtronic, Inc.) and WO 90/13332 (Cedars-Sanai Medical Center), for example.
The term “deposited” means that the active compound is coated, adsorbed, placed, or otherwise incorporated into the device by methods known in the art. For example, the active compound may be embedded and released from within (“matrix type”) or surrounded by and released through (“reservoir type”) polymer materials that coat or span the medical device. In the latter example, the active compound may be entrapped within the polymer materials or coupled to the polymer materials using one or more the techniques for generating such materials known in the art. In other formulations, the active compound may be linked to the surface of the medical device without the need for a coating, for example by means of detachable bonds, and release with time or can be removed by active mechanical or chemical processes. In other formulations, the active compound may be in a permanently immobilized form that presents the active compound at the implantation site.
In certain embodiments, the active compound may be incorporated with polymer compositions during the formation of biocompatible coatings for medical devices, such as stents. The coatings produced from these components are typically homogeneous and are useful for coating a number of devices designed for implantation.
The polymer may be either a biostable or a bioabsorbable polymer depending on the desired rate of release or the desired degree of polymer stability, but frequently a bioabsorbable polymer is suitable for this embodiment because, unlike a biostable polymer, it will typically not be present long after implantation to cause any adverse, chronic local response. Bioabsorbable polymers that could be used include, but are not limited to, poly(L-lactic acid), polycaprolactone, polyglycolide (PGA), poly(lactide-co-glycolide) (PLLA/PGA), poly(hydroxybutyrate), poly(hydroxybutyrate-co-valerate), polydioxanone, polyorthoester, polyanhydride, poly(glycolic acid), poly(D-lactic acid), poly(L-lactic acid), poly(D, L-lactic acid), poly(D, L-lactide) (PLA), poly (L-lactide) (PLLA), poly(glycolic acid-co-trimethylene carbonate) (PGA/PTMC), polyethylene oxide (PEO), polydioxanone (PDS), polyphosphoester, polyphosphoester urethane, poly(amino acids), cyanoacrylates, poly(trimethylene carbonate), poly(iminocarbonate), copoly(ether-esters) (e.g., PEO/PLA), polyalkylene oxalates, polyphosphazenes and biomolecules such as fibrin, fibrinogen, cellulose, starch, collagen and hyaluronic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacrylates, cross linked or amphipathic block copolymers of hydrogels, and other suitable bioabsorbable poplymers known in the art. Also, biostable polymers with a relatively low chronic tissue response such as polyurethanes, silicones, and polyesters could be used, and other polymers could also be used if they can be dissolved and cured or polymerized on the medical device such as polyolefins, polyisobutylene and ethylene-alphaolefin copolymers; acrylic polymers and copolymers, vinyl halide polymers and copolymers, such as polyvinyl chloride; polyvinylpyrrolidone; polyvinyl ethers, such as polyvinyl methyl ether; polyvinylidene halides, such as polyvinylidene fluoride and polyvinylidene chloride; polyacrylonitrile, polyvinyl ketones; polyvinyl aromatics, such as polystyrene, polyvinyl esters, such as polyvinyl acetate; copolymers of vinyl monomers with each other and olefins, such as ethylene-methyl methacrylate copolymers, acrylonitrile-styrene copolymers, ABS resins, and ethylene-vinyl acetate copolymers; pyran copolymer; polyhydroxy-propyl-methacrylamide-phenol; polyhydroxyethyl-aspartamide-phenol; polyethyleneoxide-polylysine substituted with palmitoyl residues; polyamides, such as Nylon 66 and polycaprolactam; alkyd resins, polycarbonates; polyoxymethylenes; polyimides; polyethers; epoxy resins, polyurethanes; rayon; rayon-triacetate; cellulose, cellulose acetate, cellulose butyrate; cellulose acetate butyrate; cellophane; cellulose nitrate; cellulose propionate; cellulose ethers; and carboxymethyl cellulose.
Polymers and semipermeable polymer matrices may be formed into shaped articles, such as valves, stents, tubing, prostheses and the like.
In certain embodiments of the invention, the compound of the invention, or pharmaceutically acceptable salt thereof, is coupled to a polymer or semipermeable polymer matrix that is formed as a stent or stent-graft device.
Typically, polymers are applied to the surface of an implantable device by spin coating, dipping, or spraying. Additional methods known in the art can also be utilized for this purpose. Methods of spraying include traditional methods as well as microdeposition techniques with an inkjet type of dispenser. Additionally, a polymer can be deposited on an implantable device using photo-patterning to place the polymer on only specific portions of the device. This coating of the device provides a uniform layer around the device which allows for improved diffusion of various analytes through the device coating.
In certain embodiments of the invention, the compound of the invention, or pharmaceutically acceptable salt thereof, is formulated for release from the polymer coating into the environment in which the medical device is placed. Preferably, the active compound is released in a controlled manner over an extended time frame (e.g., months) using at least one of several well-known techniques involving polymer carriers or layers to control elution. Some of these techniques are described in U.S. Patent Application 2004/0243225A1, the entire disclosure of which is incorporated herein in its entirety.
Moreover, as described for example in U.S. Pat. No. 6,770,729, which is incorporated herein in its entirety, the reagents and reaction conditions of the polymer compositions can be manipulated so that the release of the active compound from the polymer coating can be controlled. For example, the diffusion coefficient of the one or more polymer coatings can be modulated to control the release of the active compound from the polymer coating. In a variation on this theme, the diffusion coefficient of the one or more polymer coatings can be controlled to modulate the ability of an analyte that is present in the environment in which the medical device is placed (e.g., an analyte that facilitates the breakdown or hydrolysis of some portion of the polymer) to access one or more components within the polymer composition (and for example, thereby modulate the release of the active compound from the polymer coating). Yet another embodiment of the invention includes a device having a plurality of polymer coatings, each having a plurality of diffusion coefficients. In such embodiments of the invention, the release of the active compound from the polymer coating can be modulated by the plurality of polymer coatings.
In yet another embodiment of the invention, the release of the active compound from the polymer coating is controlled by modulating one or more of the properties of the polymer composition, such as the presence of one or more endogenous or exogenous compounds, or alternatively, the pH of the polymer composition. For example, certain polymer compositions can be designed to release an active compound in response to a decrease in the pH of the polymer composition.
It will be understood by one of ordinary skill in the relevant arts that other suitable modifications and adaptations to the compositions and methods described herein are readily apparent from the description of the invention contained herein in view of information known to the ordinarily skilled artisan, and may be made without departing from the scope of the invention or any embodiment thereof.
Having now described the present invention in detail, the same will be more clearly understood by reference to the following examples, which are included herewith for purposes of illustration only and are not intended to be limiting of the invention.

To a solution of 1-(3-bromo-5-fluoro-2-hydroxyphenyl)ethanone (4.0 g, 17.2 mmol) and CH3I (3.7 g, 25.8 mmol) in acetone (120 mL) was added K2CO3 (7.1 g, 51.5 mmol). The reaction mixture was stirred at 60° C. for 4 hours under nitrogen atmosphere. After the reaction was complete by LCMS, the reaction mixture was cooled and removed the solvent under reduced pressure. The residue was diluted with H2O (50 mL) and extracted with DCM (50 mL×3).

The bromodomain binding assay utilizes AlphaScreen technology. Compounds compete with a biotinylated peptide ligand (from histone H4: aa 1-21, K5/K8/K12/K16Ac-biotin) for binding to a hexahistidine (His6)-tagged bromodomain. Peptide binding is detected by fluorescence signal after singlet oxygen energy transfer from peptide-bound AlphaScreen streptavidin-coated donor beads to His6-tagged bromodomain-bound nickel-chelate acceptor beads (PerkinElmer). Briefly, 8 μL 2.5× bromodomain (E. coli expressed, N-terminal His6-tagged human BRD4 bromodomain II [based on Genbank NM_058243, residues 349-460] or N-terminal His6-tagged human BRD4 bromodomain I [residues 44-170]) in reaction buffer (50 mM HEPES [pH 7.5], 100 mM NaCl, 0.05% CHAPS, 0.1% BSA, 1% DMSO) is added to wells of an assay plate (384-well low flange white, flat bottom, polystyrene microplate, Corning #3572; buffer only is added to some wells as a negative control). A compound concentration series (10 concentrations, 3-fold serial dilutions previously prepared in 100% DMSO, or 100% DMSO only negative control) is delivered to the assay plate with an Echo 550 acoustic liquid handler (Labcyte), followed by plate centrifugation and incubation for 30 minutes at room temperature. Then 4 μL 5× biotinylated peptide ligand is added, followed by plate centrifugation and gentle shaking for 30 minutes at room temperature to mix. After this incubation, 4 μL 5× donor beads are added, and the plate is centrifuged, followed by brief gentle shaking to mix. Finally, 4 μL 5× acceptor beads are added, and the plate is centrifuged, followed by gentle shaking for 60 minutes at room temperature in the dark. AlphaScreen signal (excitation/emission: 680 nm/520-620 nm) is detected with an EnSpire multimode plate reader (PerkinElmer). Percentage peptide binding is plotted as a function of concentration, and curve fitting is used to determine competitive compound binding IC50s.
The cell-based assay indirectly measures cell density (and therefore proliferation and/or survival) by detecting total ATP concentration in a homogeneous format. Briefly, human SKM-1 acute myeloid leukemia cells (Leibniz Institute DSMZ #ACC 547) proliferating in log phase are collected by centrifugation, re-suspended in culture media (RPMI 1640/15% FBS/100 U/mL penicillin/100 μg/mL streptomycin) and diluted to 34722 cells/mL in media after counting. Then 180 μL cells are plated per well into a 96-well tissue-culture treated, clear bottom plate (Corning #3603). A 96-well compound plate (Corning #3357) is then generated by serial dilution of compounds into DMSO over nine concentrations and adding separate negative (DMSO) and positive control (reference compound) wells. Each compound concentration is tested in triplicate. First, 1 μL from each well of the compound plate is added to 99 μL culture media in an intermediate plate and mixed by pipetting. Then 20 μL of the diluted compounds in media are added to the assay plate containing the cells. The assay plate is maintained for 4 days in a standard cell culture incubator. At the end of the incubation period, 100 μL ATPlite 1step (PerkinElmer) is added to the assay plate wells, and the resulting luminescence is detected using an Infinite M1000 or a Spark multimode plate reader (Tecan). Data analysis is performed in Prism (GraphPad Software). For curve fitting, a non-linear regression, variable slope equation is used to calculate cellular IC50s.
Each of the example compounds in Table C1, above, demonstrates >300-fold selectivity for BDII (i.e., BDI IC50/BDII IC50>300 for each compound).
