The disclosure also provides pharmaceutically acceptable compositions comprising compounds of the present disclosure and methods of using said compositions in the treatment of proliferative disorders, such as cancers. BACKGROUND [0003] Activation of the p42/44 MAPK signaling pathway comprising mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase (MEK)-ERK has been implicated in the pathogenesis and progression of various cancers. The MEK-ERK pathway is often activated by mutation of upstream factors, BRAF or Ras, or by the signals of constitutively activated cell-surface receptors. Inhibition of MEK can be a promising strategy for controlling the growth of tumors, for example, the tumors associated with MEK pathway signaling. SUMMARY [0004] It has now been found that compounds of the present disclosure, and pharmaceutically acceptable compositions thereof, are effective as MEK inhibitors. In one aspect, the instant disclosure provides a compound of Formula (I):

The term “heterocyclylalkyl” refers to an alkyl group substituted by a heterocyclyl, wherein the alkyl and heterocyclyl portions independently are optionally substituted. [0026] As used herein, the term “partially unsaturated” refers to a ring moiety that includes at least one double or triple bond. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aryl or heteroaryl moieties, as herein defined. [0027] As described herein, compounds of the invention may contain “optionally substituted” moieties. In general, the term “substituted,” whether preceded by the term “optionally” or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable,” as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain embodiments, their recovery, purification, and use for one or more of the purposes disclosed herein.

In some embodiments, cycloalkyl radicals include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and the like. [0036] In some embodiments, halogen or halo is F, Cl, Br, or I. [0037] As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1–19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this disclosure include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2– hydroxy–ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2–naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3–phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p–toluenesulfonate, undecanoate, valerate salts, and the like. [0038] Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(C1-C4alkyl)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. [0039] 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 disclosure. Unless otherwise stated, all tautomeric forms of the compounds of the disclosure are within the scope of the disclosure. Additionally, unless otherwise stated, structures depicted herein are also meant to include 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 13C- or 14C-enriched carbon are within the scope of this disclosure. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present disclosure. [0040] As used herein, the term “provided compound” refers to any MEK inhibitor genus, subgenus, and/or species set forth herein. [0041] As used herein, the terms “inhibitor” or “MEK inhibitor” or “MEK antagonist” are defined as a compound that binds to and/or inhibits MEK with measurable affinity. In some embodiments, inhibition in the presence of a MEK inhibitor or a MEK antagonist is observed in a dose-dependent manner. In some embodiments, the measured signal (e.g., signaling activity or biological activity) is at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 100% lower than the signal measured with a negative control under comparable conditions. The potency of an inhibitor is usually defined by its IC50 value (half maximal inhibitory concentration or concentration required to inhibit 50% of the agonist response). The lower the IC50 value the greater the potency of the antagonist and the lower the concentration that is required to inhibit the maximum biological response. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less than about 100 ^M, less than about 50 ^M, less than about 1 ^M, less than about 500 nM, less than about 100 nM, less than about 10 nM, or less than about 1 nM. [0042] The terms “measurable affinity” and “measurably inhibit,” as used herein, means a measurable change or inhibition in MEK activity between a sample comprising a compound of the present disclosure, or composition thereof, and MEK, and an equivalent sample comprising MEK, in the absence of said compound, or composition thereof. [0043] As used herein, the term “effective amount” refers to the amount of a compound sufficient to effect beneficial or desired results (e.g., a therapeutic, ameliorative, inhibitory, or preventative result). An effective amount can be administered in one or more administrations, applications, or dosages and is not intended to be limited to a particular formulation or administration route. [0044] As used herein, the term “treating” includes any effect, e.g., lessening, reducing, modulating, ameliorating or eliminating, that results in the improvement of the condition, disease, disorder, and the like, or ameliorating a symptom thereof. In some embodiments, treatment can be administered after one or more symptoms have developed. In other embodiments, treatment can be administered in the absence of symptoms. For example, treatment can be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment can also be continued after symptoms have resolved, for example, to prevent or delay their recurrence. [0045] The phrases “disorder mediated by MEK” or “disease mediated by MEK” or “MEK- associated disease or disorder,” as used herein, refer to diseases or disorders associated with, or mediated by MEK or MEK activity. A non-limiting example of a MEK-associated disease or disorder is a MEK-associated cancer. [0046] As used herein, the term “pharmaceutical composition” refers to the combination of an active agent with a carrier, inert or active, making the composition especially suitable for diagnostic or therapeutic use in vivo or ex vivo. [0047] As used herein, the term “pharmaceutically acceptable carrier” refers to any of the standard pharmaceutical carriers, such as a phosphate buffered saline solution, water, emulsions (e.g., such as an oil/water or water/oil emulsions), and various types of wetting agents. The compositions also can include stabilizers and preservatives. For examples of carriers, stabilizers and adjuvants, see e.g., Martin, Remington’s Pharmaceutical Sciences, 15th Ed., Mack Publ. Co., Easton, PA [1975]. [0048] As used herein, a “non-ATP competitive” or “ATP non-competitive” MEK inhibitor refers to an inhibitor of MEK that does not bind in the ATP pocket of MEK, or does not displace ATP from the MEK active site, and can form direct contacts when co-bound to the MEK-ATP complex. Non-ATP competitive inhibition by a compound of the invention can be confirmed by art-recognized methods such as enzymology studies, competition assays, biophysical methods, including X-ray co-crystallography. An exemplary non-ATP competitive inhibitor of the invention inhibits recombinant MEK1 or MEK2 with an IC50 of from about 1 nM to about 50 µM. In some embodiments, an exemplary non-ATP competitive inhibitor of the invention inhibits recombinant MEK1 or MEK2 with an IC50 of about 1 nM to about 1000 nM, about 1 µM to about 50 µM, about 1 µM to about 25 µM, about 1 µM to about 10 µM, about 500 nM to about 5 µM, or about 10 nM to about 500 nM. [0049] An “inhibitor pocket”, as used herein, refers to a structure formed at the interface of the interaction between MEK and KSR or BRAF or CRAF with which an inhibitor of the invention is engaged. [0050] The term “trapping,” as used herein, refers to when an inhibitor of the present disclosure binds to and stabilizes the CRAF-MEK complex in an inactive conformation. [0051] As used herein, a compound of the invention “allosterically binds an inhibitor pocket” when a compound binds outside the active site, including, for example, outside or adjacent to the ATP-binding site of a kinase. [0052] As used herein, an “inhibitor-inhibitor pocket complex” describes a species in which an inhibitor of the invention allosterically binds an inhibitor pocket formed at an interaction interface between human MEK (MEK1 or MEK2) and human Kinase Suppressor of Ras (KSR1, KSR2, or the KSR homolog BRAF or CRAF) adjacent to ATP in a physiological complex between MEK and KSR. [0053] As used herein, when a moiety on an inhibitor “engages” an amino acid residue of MEK and/or KSR and/or BRAF or CRAF in an inhibitor pocket, this interaction is detectable by X-ray crystallography, or similar structural methods, such as cryo-electron microscopy, NMR, or in silico docking, including fragment binding and computational simulations, which demonstrates that the interaction defining the engagement is a separation between the inhibitor moiety and the amino acid residue of not more than about 8 Å, including, for example, from about 2 Å to about 5 Å, or from 5 Å to about 8 Å. The distances provided herein allow for the implicit inclusion of hydrogen atoms; however, hydrogen atoms were not included in the present crystallographic models, which is appropriate unless crystals diffract to very high resolutions (i.e., better than 1.5 Angstroms). Literature surveys of drug-receptor atom pairs across all structures in the protein data bank have used 4-5 Angstrom distance cutoffs (PMID 29308120, 26517868, 19221587) to evaluate reasonable small molecule hydrophobic bonding interactions and have found that intermolecular carbon-carbon interactions similar to the trametinib-KSR contacts are among the most highly represented drug-receptor atom pairs within the protein data bank. With respect to the interactions between the inhibitors of the invention and the MEK-KSR and/or BRAF or CRAF complex, a 4 Angstrom contact is reasonable based on the nature of the trametinib-KSR interaction and precedence of known drug-receptor complexes. This contact is within the range of known contacts as defined by several independent groups (PMID 29308120, 26517868, 19221587). 2.

[0097] In some embodiments, the present disclosure provides a compound set forth in Table 1 above, or a pharmaceutically acceptable salt thereof. 3. Uses, Formulation, and Administration: Pharmaceutically acceptable compositions [0098] According to another embodiment, the disclosure provides a pharmaceutical composition comprising a compound of this disclosure or a pharmaceutically acceptable derivative thereof and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The amount of compound in compositions of this disclosure is such that is effective to measurably inhibit MEK, or a variant or mutant thereof, in a biological sample or in a patient. In certain embodiments, the amount of compound in compositions of this disclosure is such that is effective to measurably inhibit MEK, or a variant or mutant thereof, in a biological sample or in a patient. In certain embodiments, a composition of this disclosure is formulated for administration to a patient in need of such composition. In some embodiments, a composition of this disclosure is formulated for oral administration to a patient. [0099] As used herein, the terms “subject” and “patient” are used interchangeably and refer to organisms to be treated by the methods of the present disclosure. Such organisms preferably include, but are not limited to, mammals (e.g., murines, simians, equines, bovines, porcines, canines, felines, and the like), and, most preferably, includes humans. [00100] The term “pharmaceutically acceptable carrier, adjuvant, or vehicle” refers to a non- toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions of this disclosure include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene- polyoxypropylene-block polymers, polyethylene glycol and wool fat. [00101] A “pharmaceutically acceptable derivative” means any non-toxic salt, ester, salt of an ester or other derivative of a compound of this disclosure that, upon administration to a recipient, is capable of providing, either directly or indirectly, a compound of this disclosure or an active metabolite or residue thereof. [00102] As used herein, the term "active metabolite or residue thereof" means that a metabolite or residue thereof also inhibits MEK, or a variant or mutant thereof. [00103] Compositions of the present disclosure can be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term "parenteral" as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this disclosure may be aqueous or oleaginous suspension. These suspensions can be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer’s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. [00104] For this purpose, any bland fixed oil can be employed including synthetic mono- or di- glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions can also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation. [00105] Pharmaceutically acceptable compositions of this disclosure can be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents can also be added. [00106] Alternatively, pharmaceutically acceptable compositions of this disclosure can be administered in the form of suppositories for rectal administration.

[00144] The compounds and compositions, according to the method of the present disclosure, may be administered using any amount and any route of administration effective for inhibiting MEK and treating or lessening the severity of a disease, for example, as those described herein. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the disease or condition, the particular agent, its mode of administration, and the like. Compounds of the disclosure are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present disclosure will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. The term “patient”, as used herein, means an animal, preferably a mammal, and most preferably a human. [00145] Pharmaceutically acceptable compositions of this disclosure can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the disease or disorder being treated. In certain embodiments, the compounds of the disclosure may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect. [00146] Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, 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, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. [00147] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer’s solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables. [00148] Injectable formulations can be sterilized, for example, by filtration through a bacterial- retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use. [00149] In order to prolong the effect of a compound of the present disclosure, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide- polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues. [00150] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this disclosure with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound. [00151] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. [00152] 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 sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. 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 sugar as well as high molecular weight polethylene glycols and the like. [00153] The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. [00154] Dosage forms for topical or transdermal administration of a compound of this disclosure include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this disclosure. Additionally, the present disclosure contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel. Co-Administration with One or More Other Therapeutic Agent(s) [00155] Depending upon the particular condition, or disease, to be treated, additional therapeutic agents that are normally administered to treat that condition, can also be present in the compositions of this disclosure. As used herein, additional therapeutic agents that are normally administered to treat a particular disease, or condition, are known as "appropriate for the disease, or condition, being treated." [00156] In some embodiments, the present disclosure provides a method of treating a disclosed disease or condition comprising administering to a patient in need thereof an effective amount of a compound disclosed herein or a pharmaceutically acceptable salt thereof and co-administering simultaneously or sequentially an effective amount of one or more additional therapeutic agents, such as those described herein. In some embodiments, the method includes co-administering one additional therapeutic agent. In some embodiments, the method includes co-administering two additional therapeutic agents. In some embodiments, the combination of the disclosed compound and the additional therapeutic agent or agents acts synergistically. [00157] A compound of the current disclosure can be administered alone or in combination with one or more other therapeutic compounds, possible combination therapy taking the form of fixed combinations or the administration of a compound of the disclosure and one or more other therapeutic compounds being staggered or given independently of one another, or the combined administration of fixed combinations and one or more other therapeutic compounds. [00158] One or more other therapeutic agent(s) can be administered separately from a compound or composition of the disclosure, as part of a multiple dosage regimen. Alternatively, one or more other therapeutic agent(s) may be part of a single dosage form, mixed together with a compound of this disclosure in a single composition. If administered as a multiple dosage regime, one or more other therapeutic agent(s) and a compound or composition of the disclosure can be administered simultaneously, sequentially or within a period of time from one another, for example within 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours from one another. In some embodiments, one or more other therapeutic agent(s) and a compound or composition of the disclosure are administered as a multiple dosage regimen within greater than 24 hours apart. [00159] As used herein, the term "combination," "combined," and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this disclosure. For example, a compound of the present disclosure can be administered with one or more other therapeutic agent(s) simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present disclosure provides a single unit dosage form comprising a compound of the current disclosure, one or more other therapeutic agent(s), and a pharmaceutically acceptable carrier, adjuvant, or vehicle. [00160] The amount of a compound of the disclosure and one or more other therapeutic agent(s) (in those compositions which comprise an additional therapeutic agent as described above) that can be combined with the carrier materials to produce a single dosage form varies depending upon the host treated and the particular mode of administration. Preferably, a composition of the disclosure should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of a compound of the disclosure can be administered. [00161] In those compositions which comprise one or more other therapeutic agent(s), the one or more other therapeutic agent(s) and a compound of the disclosure can act synergistically. Therefore, the amount of the one or more other therapeutic agent(s) in such compositions may be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01 - 1,000 g/kg body weight/day of the one or more other therapeutic agent(s) can be administered. [00162] The amount of one or more other therapeutic agent(s) present in the compositions of this disclosure may be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of one or more other therapeutic agent(s) in the presently disclosed compositions ranges from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent. In some embodiments, one or more other therapeutic agent(s) is administered at a dosage of about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, or about 95% of the amount normally administered for that agent. As used herein, the phrase "normally administered" means the amount an FDA approved therapeutic agent is approved for dosing per the FDA label insert. [00163] The compounds of this disclosure, or pharmaceutical compositions thereof, can also be incorporated into compositions for coating an implantable medical device, such as prostheses, artificial valves, vascular grafts, stents and catheters. Vascular stents, for example, have been used to overcome restenosis (re-narrowing of the vessel wall after injury). However, patients using stents or other implantable devices risk clot formation or platelet activation. These unwanted effects may be prevented or mitigated by pre-coating the device with a pharmaceutically acceptable composition comprising a kinase inhibitor. Implantable devices coated with a compound of this disclosure are another embodiment of the present disclosure.

[00269] In some embodiments, an immuno-oncology agent is a T-cell engineered to express a chimeric antigen receptor, or CAR. The T-cells engineered to express such chimeric antigen receptor are referred to as a CAR-T cells. [00270] CARs have been constructed that consist of binding domains, which may be derived from natural ligands, single chain variable fragments (scFv) derived from monoclonal antibodies specific for cell-surface antigens, fused to endodomains that are the functional end of the T-cell receptor (TCR), such as the CD3-zeta signaling domain from TCRs, which is capable of generating an activation signal in T lymphocytes. Upon antigen binding, such CARs link to endogenous signaling pathways in the effector cell and generate activating signals similar to those initiated by the TCR complex. [00271] For example, in some embodiments the CAR-T cell is one of those described in U.S. Patent 8,906,682 (June et al.; hereby incorporated by reference in its entirety), which discloses CAR-T cells engineered to comprise an extracellular domain having an antigen binding domain (such as a domain that binds to CD19), fused to an intracellular signaling domain of the T cell antigen receptor complex zeta chain (such as CD3 zeta). When expressed in the T cell, the CAR is able to redirect antigen recognition based on the antigen binding specificity. In the case of CD19, the antigen is expressed on malignant B cells. Over 200 clinical trials are currently in progress employing CAR-T in a wide range of indications. [https://clinicaltrials.gov/ct2/results?term=chimeric+antigen+receptors&pg=1].

In some embodiments, an immuno-oncology agent is a small molecule agent selected from those listed in Table 2 of Jerry L. Adams et al. [00278] In some embodiments, an immuno-oncology agent is selected from the small molecule immuno-oncology agents described in Peter L. Toogood, “Small molecule immuno-oncology therapeutic agents,” Bioorganic & Medicinal Chemistry Letters 2018, Vol.28, pages 319-329, the content of which is incorporated herein by reference in its entirety. In some embodiments, an immuno-oncology agent is an agent targeting the pathways as described in Peter L. Toogood. [00279] In some embodiments, an immuno-oncology agent is selected from those described in Sandra L. Ross et al., “Bispecific T cell engager (BITE®) antibody constructs can mediate bystander tumor cell killing”, PLoS ONE 12(8): e0183390, the content of which is incorporated herein by reference in its entirety. In some embodiments, an immuno-oncology agent is a bispecific T cell engager (BITE®) antibody construct. In some embodiments, a bispecific T cell engager (BITE®) antibody construct is a CD19/CD3 bispecific antibody construct.

In some embodiments, a bispecific T cell engager (BITE®) antibody construct activates T cells which result in induced bystander cell lysis. In some embodiments, the bystander cells are in solid tumors. In some embodiments, the bystander cells being lysed are in proximity to the BITE®-activated T cells. In some embodiment, the bystander cells comprises tumor-associated antigen (TAA) negative cancer cells. In some embodiment, the bystander cells comprise EGFR-negative cancer cells. In some embodiments, an immuno- oncology agent is an antibody which blocks the PD-L1/PD1 axis and/or CTLA4.

Exemplary Immune Checkpoint Inhibitors [00280] In some embodiments, an immuno-oncology agent is an immune checkpoint inhibitor as described herein. [00281] The term “checkpoint inhibitor” as used herein relates to agents useful in preventing cancer cells from avoiding the immune system of the patient. One of the major mechanisms of anti-tumor immunity subversion is known as “T-cell exhaustion,” which results from chronic exposure to antigens that has led to up-regulation of inhibitory receptors. These inhibitory receptors serve as immune checkpoints in order to prevent uncontrolled immune reactions. [00282] PD-1 and co-inhibitory receptors such as cytotoxic T-lymphocyte antigen 4 (CTLA-4, B and T Lymphocyte Attenuator (BTLA; CD272), T cell Immunoglobulin and Mucin domain-3 (Tim-3), Lymphocyte Activation Gene-3 (Lag-3; CD223), and others are often referred to as a checkpoint regulators. They act as molecular “gatekeepers” that allow extracellular information to dictate whether cell cycle progression and other intracellular signaling processes should proceed. [00283] In some embodiments, an immune checkpoint inhibitor is an antibody to PD-1. PD-1 binds to the programmed cell death 1 receptor (PD-1) to prevent the receptor from binding to the inhibitory ligand PDL-1, thus overriding the ability of tumors to suppress the host anti-tumor immune response. [00284] In one aspect, the checkpoint inhibitor is a biologic therapeutic or a small molecule. In another aspect, the checkpoint inhibitor is a monoclonal antibody, a humanized antibody, a fully human antibody, a fusion protein or a combination thereof. In a further aspect, the checkpoint inhibitor inhibits a checkpoint protein selected from CTLA-4, PDL1, PDL2, PD1, B7-H3, B7-H4, BTLA, HVEM, TIM3, GAL9, LAG3, VISTA, KIR, 2B4, CD160, CGEN-15049, CHK 1, CHK2, A2aR, B-7 family ligands or a combination thereof. In an additional aspect, the checkpoint inhibitor interacts with a ligand of a checkpoint protein selected from CTLA-4, PDL1, PDL2, PDl, B7-H3, B7-H4, BTLA, HVEM, TIM3, GAL9, LAG3, VISTA, KIR, 2B4, CD160, CGEN-15049, CHK 1, CHK2, A2aR, B-7 family ligands or a combination thereof. In an aspect, the checkpoint inhibitor is an immunostimulatory agent, a T cell growth factor, an interleukin, an antibody, a vaccine or a combination thereof. In a further aspect, the interleukin is IL-7 or IL-15. In a specific aspect, the interleukin is glycosylated IL-7. In an additional aspect, the vaccine is a dendritic cell (DC) vaccine. [00285] Checkpoint inhibitors include any agent that blocks or inhibits in a statistically significant manner, the inhibitory pathways of the immune system. Such inhibitors may include small molecule inhibitors or may include antibodies, or antigen binding fragments thereof, that bind to and block or inhibit immune checkpoint receptors or antibodies that bind to and block or inhibit immune checkpoint receptor ligands.

EXAMPLE 3: Immunoprecipitation Assay [00380] Immunoprecipitation experiments were performed by plating about 450,000 HCT116 cells per well in 6-well plates. Cells were plated for 48 h so as to reach approximately 70% confluency before transfection. Then, 24 h after transfection, cells were treated with vehicle (0.1% DMSO) or a compound (about 200 nM) for 1 h. Cells were washed twice in cold PBS and then transferred to a pre-chilled tube in 0.6 ml of PBS solution. Cells were spun at 1,800g in a cold centrifuge for 10 min, and supernatant was aspirated. To lyse cells, pellets were resuspended in NP-40 buffer (50 mM Tris pH 7.8, 100 mM NaCl, 0.5% (v/v) NP-40, 10% (v/v) glycerol, 1 mM EDTA) supplemented with protease and phosphatase inhibitor cocktail (Thermo Fisher, 78440) and incubated on ice for 30 min. Lysates were centrifuged for 20 min at 2,100g, and supernatants are collected. Cleared lysates were quantified using BCA reagent (Pierce, 23225), with BSA as a standard. Five micrograms of rabbit anti-MEK1 antibody (Millipore-Sigma, 07-641), or rabbit IgG (Millipore Sigma, 12-370), was immobilized on 50 µl of Sepharose Protein A Resin (Thermo Fisher, 53139) and washed three times in 300 μl NP-40 buffer before initiating immunoprecipitations. [00381] Next, for MEK1 immunoprecipitation, 250 μg of total cell lysate in a total volume of 0.6 ml was mixed with the pre-immobilized anti-MEK1 antibody pre-conjugated to Protein A resin. Samples were incubated at 4 °C on an end-over-end rotator for 4 h, followed by three washes in 0.6 ml volume of NP-40 buffer. Next, proteins were denatured and released from resin by the addition of 80 µl volume of 1× SDS sample buffer. Samples were boiled at 90 °C for 2 min, spun, and then applied to a 4–12% bis-tris glycine gel (Bio-Rad, 3450125) ran in MOPS-SDS buffer (Thermo Fisher, NP0001) for 60 min at 150 V. Gels were then transferred onto nitrocellulose in 20% methanol in Tris-glycine buffer (95 V, 250 A). Transfers were confirmed using Ponceau red and then analyzed by western blot. Signals for MEK, Flag-tagged proteins, BRAF, and GAPDH were detected by enhanced chemiluminescence on a ChemDoc XRS+ imaging system (Biorad). [00382] Experimental results are provided in Table 3, below. The compound numbers correspond to the compound numbers in Table 1. The activity is classified as A-D, wherein A represents IC50 < 100 nM; B represents 100 nM ≤ IC50 < 1 uM; C represents 1 ≤ IC50 < 10 uM; and D represents IC50 ≥10 uM. TABLE 3.

EXAMPLE 4: Biological Assay for Inhibiting Mouse Xenograft Tumor Growth [00385] Exemplary compounds having MEK inhibitory activity can be tested, alone or in combination with a second anti-cancer agent, such as a TEAD inhibitor or an ERK5 inhibitor, for ability to inhibit tumor growth in patient-derived mouse xenograft models of pancreatic cancer and lung cancer. Assay procedures are described below. Procedures for Patient-Derived Mouse Xenograft (PDX) Tumor Growth Assay [00386] Balb/c mice (6-8 weeks old) are inoculated subcutaneously in the right flank with a primary human tumor xenograft model tumor fragment (2-3 mm3 in diameter) for tumor development. In one study, mice are inoculated with a human lung adenocarcinoma tumor model (MSCLC, ADC model LU6424) that harbors a BRAF mutation (LU6424); in a second study, mice are inoculated with a human pancreatic tumor model (adenosquamous carcinoma model PA6258) with a K-Ras G12D mutation (PA6258). When mean tumor volume reaches approximately 150- 200 mm3, animals are randomly allocated to appropriate treatment groups. Mice are treated with one of the following: (1) Vehicle control, (2) Exemplary MEK inhibitor alone, (3) Second anti- cancer agent alone, or (4) Combination of MEK inhibitor and second anti-cancer agent. Tumors are measured twice per week using calipers. EXAMPLE 5: Mouse Pharmacokinetic Studies [00387] Exemplary compounds were tested to determine their pharmacokinetic properties in mice using cassette dosing protocols. Assay procedures and results are described below. Part I – Procedures for Mouse Casette Pharmacokinetics Studies [00388] Pharmacokinetics studies are conducted using cassette dosing protocols, with test compounds administered per mouse. Treatment groups are 3 mice (~6-8 week old, ~20-30g balb/c male mice) per route of administration. Compounds are formulated in 5% DMSO and 95% PEG400 with final concentrations of 0.5 mg/mL for IV and PO dosing. Compounds are dosed at 2 mg/kg for IV dosing and 5 mg/kg for PO dosing. Blood samples are withdrawn at 0.083, 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, and 24 hours following IV dosing, and 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, and 24 hours following PO dosing. Blood samples are centrifuged at 4,000 g for 5 minutes at 4 °C to obtain plasma samples. Plasma samples are diluted with acetonitrile containing internal standard, vortexed for 30 seconds, then centrifuged at 4,000 rpm for 15 minutes at 4 °C. The supernatant is diluted with water, and compound concentration is determined by HPLC/MS/MS compared to calibration standards of 0.5-1,000 ng/mL. EXAMPLE 6: In vivo efficacy studies using human MIA PaCa-2 xenografts in mice [00389] The antitumor activity of MEKi was evaluated in vivo using a human cell line derived xenografts grown from MIA PaCa-2 cell line in immunodeficient mice. The tumor cell lines are maintained in vitro as monolayer culture in medium at 37°C in an atmosphere of 5% CO2 in air. The tumor cells are routinely sub-cultured before confluence by trypsin-EDTA treatment, not to exceed 4-5 passages. The cells growing in an exponential growth phase are harvested for tumor inoculation. MIA PaCa-2 tumor cells (1 x 106 cells) were implanted into Nu/Nu nude mice subcutaneously on the right flank with tumor cells in a 1:1 mixture with matrigel. Tumors are allowed to grow to approximately 250 mm3. At this time, mice are assigned to groups such that the mean tumor volume is the same for each treatment group (n = 8 mice/group). Compounds were administrated to the tumor-bearing mice via QD oral gavage at a dose of 1 mg/kg. After 10 days of dosing, when tumors in the vehicle control mice reached the ethical endpoint (mean tumor volume > 1500 mm3).
