The BRAF V600X (i.e., V600E) mutant form of BRAF is known to be oncogenic, and there are multiple BRAF inhibitors now marketed to inhibit the signaling of oncogenic BRAF V600E in melanoma and other cancers. BRAF V600E signals as a monomer and is constitutively active independent of upstream control by RAS. The marketed BRAF V600E inhibitors include vemurafenib, dabrafenib, and encorafenib.
Other than BRAF V600X mutants, almost all other oncogenic forms of BRAF signal through the formation of homodimers (BRAF-BRAF dimer) or heterodimers (e.g., BRAF-CRAF dimer) that are refractory to BRAF inhibitors such as vemurafenib, dabrafenib, and encorafenib. Such dimers are formed in cancers driven by BRAF fusions, atypical BRAF mutations, or RAS mutant cancers.
Oncogenic BRAF fusions originate from genomic rearrangements placing the 3-prime portion of the BRAF gene encoding the kinase domain behind another gene at the 5-prime position. The rearrangements result in the expression of oncoproteins that express constitutive kinase activity due to loss of the N-terminal auto-inhibitory domain of BRAF resulting from the genomic rearrangements. These BRAF fusions exhibit constitutive kinase activity due to spontaneous dimerization and as such are capable of aberrant signaling in cancer cells independent of upstream effectors or regulatory mechanisms. Additionally, some 5-prime translocated rearrangement genes contribute the N-terminal domains to be capable of further inducing dimerization, thereby enhancing activating dimerization of the BRAF fusion protein kinase domain. Since the expression of these genomic rearrangements are controlled by the promoter of the 5-prime partner, often there is overexpression of the BRAF fusion transcript due to efficient or excessive promoter activity. BRAF fusions are among the most common kinase translocations in solid tumors. Since their first description in 2005 as oncogenes in papillary thyroid carcinoma, hundreds of tumors in which the BRAF kinase domain is fused to one of more than 110 different 5-prime partner genes have been identified across at least 15 different tumor types. BRAF fusions are found in papillary thyroid carcinoma, astrocytomas, melanomas, and have also been identified in drug resistant EGFR mutant lung cancers. BRAF fusion proteins signal by dimerization in a RAS-independent manner and are resistant to many BRAF inhibitors such as vemurafenib and dabrafenib, that are not capable of inhibiting both protomers of the signaling homodimer BRAF fusions. Rare CRAF fusion proteins have also been demonstrated to be tumor drivers. Such CRAF fusion proteins signal as CRAF-CRAF homodimers.
Other so-called atypical BRAF mutations also lead to spontaneous dimerization and signaling independent of RAS control. Like BRAF fusions, these atypical BRAF mutants signal as aberrant homodimers.
RAS mutant cancers comprise approximately 26-30% of all human cancers. RAS mutant cancers signal through the RAS→RAF→MEK→ERK MAPK signaling pathway. In this signaling cascade, kinase-inactive RAF monomers (comprising ARAF, BRAF, CRAF isoforms) are recruited to oncogenic RAS where RAS induces the formation of kinase-active signaling RAF dimers. A predominant RAF heterodimer that is recruited to mutant RAS is the BRAF/CRAF heterodimer.
A combinatorial siRNA screening approach identified RAF as a dominant node in RAS mutant cancers, and that codepletion of both BRAF and CRAF, together with depletion of the autophagy gene ATG7, gave the best synthetic lethal inhibition of RAS mutant signaling, and additionally afforded the best therapeutic window for inhibiting signaling in RAS mutant cells versus normal, RAS wildtype cells. Additionally, it has been reported that inhibition of the RAF→MEK→ERK pathway in combination with autophagy-inhibiting agents effectively blocked RAS mutant cancer growth in vitro and in vivo.
Vertical inhibition of the RAF→MEK→ERK pathway through pan inhibition of RAF (specifically BRAF+CRAF) and ERK kinase activities were shown to illicit high synergy in blocking MAPK pathway signaling in KRAS-mutant pancreatic cancer cells, organoid studies, as well as in murine models of KRAS mutant pancreatic cancer. Vertical inhibition of RAF (BRAF+CRAF) and MEK kinase activities was also shown to be synergistic in KRAS mutant tumors.
The importance of inhibiting both BRAF and CRAF isoforms, as well as the requirement of inhibitor successfully binding to and inhibiting both protomers of signaling RAF dimers, has been well demonstrated. Failure of a RAF inhibitor, especially BRAF inhibitors, to successfully bind to and inhibit both protomers of signaling RAF dimers in RAS mutant cancers leads to paradoxical pathway stimulation rather than the desired pathway inhibition. Such BRAF inhibitors are contraindicated for the treatment of RAS mutant cancers.
There is a need to identify RAF inhibitors that can inhibit multiple RAF isoforms. Particularly, there is a need to identify RAF inhibitors that can inhibit both BRAF and CRAF isoforms. Especially, there is a need to identify RAF inhibitors that can inhibit both RAF protomers present in signaling BRAF/BRAF homodimers and both protomers in BRAF/CRAF heterodimers. Such pan RAF inhibitors find utility in the treatment of BRAF V600X driven cancers, atypical BRAF mutated cancers, BRAF fusion cancers, CRAF fusion cancers, and RAS mutant cancers.
Described herein, are compounds that are RAF inhibitors. and methods of use thereof. In some embodiments, the compounds are BRAF or CRAF inhibitors. In some embodiments, the compounds are useful for the treatment of cancers driven by oncogenic forms of RAS or BRAF. In some embodiments, the compounds inhibit both BRAF and CRAF isoforms. In some other embodiments, the compounds inhibit both RAF protomers present in signaling BRAF/BRAF homodimers and both protomers present in signaling BRAF/CRAF heterodimers. In some other embodiments, the compounds inhibit ARAF, BRAF, and CRAF present in signaling homodimers or heterodimers.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which the subject matter herein belongs. As used in the specification and the appended claims, unless specified to the contrary, the following terms have the meaning indicated in order to facilitate the understanding of the present disclosure.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents, positions of substituents and/or variables are permissible only if such combinations result in stable compounds.
As used herein, the singular forms “a”, “an”, and “the” encompass plural references unless the context clearly indicates otherwise.
As used herein, the term “herein” means the entire application.
As used herein, “deuterated” mean that at least one hydrogen atom is replaced by deuterium.

Another aspect of this disclosure provides pharmaceutical compositions comprising compounds as disclosed herein formulated together with a pharmaceutically acceptable carrier. In particular, the present disclosure provides pharmaceutical compositions comprising compounds as disclosed herein formulated together with one or more pharmaceutically acceptable carriers. These formulations include those suitable for oral, rectal, topical, buccal, parenteral (e.g., subcutaneous, intramuscular, intradermal, or intravenous) rectal, vaginal, or aerosol administration, although the most suitable form of administration in any given case will depend on the degree and severity of the condition being treated and on the nature of the particular compound being used. For example, disclosed compositions may be formulated as a unit dose, and/or may be formulated for oral or subcutaneous administration.
Exemplary pharmaceutical compositions may be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which contains one or more of the compounds described herein, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of the disease.
For preparing solid compositions such as tablets, the principal active ingredient may be mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g., water, to form a solid preformulation composition containing a homogeneous mixture of a compound provided herein, or a non-toxic pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills, and capsules.
In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules and the like), the subject composition 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; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, the compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.
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 subject composition moistened with an inert liquid diluent. Tablets, and other solid dosage forms, 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.
Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous, or organic solvents, or mixtures thereof, and powders. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the subject composition, 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, cyclodextrins and mixtures thereof.
Suspensions, in addition to the subject composition, 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.
Formulations for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing a subject composition with one or more suitable non-irritating 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 body cavity and release the active agent.
Dosage forms for transdermal administration of a subject composition include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active component may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants which may be required.
The ointments, pastes, creams and gels may contain, in addition to a subject composition, 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.
Powders and sprays may contain, in addition to a subject composition, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays may additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
Compositions and compounds of the present disclosure may alternatively be administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation or solid particles containing the compound. A non-aqueous (e.g., fluorocarbon propellant) suspension could be used. Sonic nebulizers may be used because they minimize exposing the agent to shear, which may result in degradation of the compounds contained in the subject compositions. Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of a subject composition together with conventional pharmaceutically acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular subject composition, but typically include non-ionic surfactants (Tweens, Pluronics, or polyethylene glycol), innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars or sugar alcohols. Aerosols generally are prepared from isotonic solutions.
Pharmaceutical compositions of the present disclosure suitable for parenteral administration comprise a subject composition in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or non-aqueous 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 antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.
Examples of suitable aqueous and non-aqueous carriers which may be employed in the pharmaceutical compositions provided herein 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 and cyclodextrins. Proper fluidity may 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.
In another embodiment, provided are enteral pharmaceutical formulations including a disclosed compound and an enteric material, and a pharmaceutically acceptable carrier or excipient thereof. Enteric materials refer to polymers that are substantially insoluble in the acidic environment of the stomach, and that are predominantly soluble in intestinal fluids at specific pHs. The small intestine is the part of the gastrointestinal tract (gut) between the stomach and the large intestine, and includes the duodenum, jejunum, and ileum. The pH of the duodenum is about 5.5, the pH of the jejunum is about 6.5 and the pH of the distal ileum is about 7.5.
Accordingly, enteric materials are not soluble, for example, until a pH of about 5.0, of about 5.2, of about 5.4, of about 5.6, of about 5.8, of about 6.0, of about 6.2, of about 6.4, of about 6.6, of about 6.8, of about 7.0, of about 7.2, of about 7.4, of about 7.6, of about 7.8, of about 8.0, of about 8.2, of about 8.4, of about 8.6, of about 8.8, of about 9.0, of about 9.2, of about 9.4, of about 9.6, of about 9.8, or of about 10.0. Exemplary enteric materials include cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), hydroxypropyl methylcellulose acetate succinate (HPMCAS), cellulose acetate trimellitate, hydroxypropyl methylcellulose succinate, cellulose acetate succinate, cellulose acetate hexahydrophthalate, cellulose propionate phthalate, cellulose acetate maleate, cellulose acetate butyrate, cellulose acetate propionate, copolymer of methylmethacrylic acid and methyl methacrylate, copolymer of methyl acrylate, methylmethacrylate and methacrylic acid, copolymer of methylvinyl ether and maleic anhydride (Gantrez ES series), ethyl methyacrylate-methylmethacrylate-chlorotrimethylammonium ethyl acrylate copolymer, natural resins such as zein, shellac and copal collophorium, and several commercially available enteric dispersion systems (e.g., Eudragit L30D55, Eudragit FS30D, Eudragit L100, Eudragit S100, Kollicoat EMM30D, Estacryl 30D, Coateric, and Aquateric). The solubility of each of the above materials is either known or is readily determinable in vitro. The foregoing is a list of possible materials, but one of skill in the art with the benefit of the disclosure would recognize that it is not comprehensive and that there are other enteric materials that would meet the objectives described herein.
Advantageously, provided herein are kits for use by a e.g., a consumer in need of treatment of cancer. Such kits include a suitable dosage form such as those described above and instructions describing the method of using such dosage form to mediate, reduce or prevent inflammation. The instructions would direct the consumer or medical personnel to administer the dosage form according to administration modes known to those skilled in the art. Such kits could advantageously be packaged and sold in single or multiple kit units. An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process recesses are formed in the plastic foil. The recesses have the size and shape of the tablets or capsules to be packed. Next, the tablets or capsules are placed in the recesses and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are sealed in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening.
It may be desirable to provide a memory aid on the kit, e.g., in the form of numbers next to the tablets or capsules whereby the numbers correspond with the days of the regimen which the tablets or capsules so specified should be ingested. Another example of such a memory aid is a calendar printed on the card, e.g., as follows “First Week, Monday, Tuesday, . . . etc. . . . Second Week, Monday, Tuesday, . . . ” etc. Other variations of memory aids will be readily apparent. A “daily dose” can be a single tablet or capsule or several pills or capsules to be taken on a given day. Also, a daily dose of a first compound can consist of one tablet or capsule while a daily dose of the second compound can consist of several tablets or capsules and vice versa. The memory aid should reflect this.
The compounds described herein can be prepared in a number of ways based on the teachings contained herein and synthetic procedures known in the art. In the description of the synthetic methods described below it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, can be chosen to be the conditions standard for that reaction, unless otherwise indicated. 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. The starting materials for the examples are either commercially available or are readily prepared by standard methods from known materials.
