Description

[0003] The RAS/MAPK pathway is activated in response to growth factor binding and regulates cellular growth, differentiation and survival in a variety of cell types. Activation of this pathway occurs via a cascade of protein phosphorylation events, which culminates in the phosphorylation and activation of ERK (ERK1 and/or ERK2). ERK lies downstream from the small GTPase RAS and the protein kinases RAF and MEK in the RAS/MAPK pathway. Following its activation by RAS, RAF phosphorylates MEK, which in turn phosphorylates ERK. Activated ERK phosphorylates other substrates that govern the transcriptional output of cells.

DETAILED DESCRIPTION

[0011] Inhibition of ERK can have therapeutic effects in the treatment of certain types of cancer. It has been shown that the RAS/MAPK/ERK pathway can be aberrantly activated in certain tumors via activating mutations in RAS and BRAF, and this activation has been implicated in the growth and pathologic behavior of certain cancer cells. Constitutive activation of this pathway has been observed in human cancers and has been associated with high rates of cancer cell proliferation. Tumor cells that harbor either BRAF or RAS mutations are generally dependent on the activity of the altered proteins for growth and survival, a phenomenon described as "oncogene addiction." Activating mutations of RAS have been reported in -30% of all cancers, with some, such as pancreatic and colon cancer, harboring mutation rates of -90% and -50%, respectively. RAS mutations have been identified in -15% of melanomas and -30% of NSCLCs (non-small cell lung cancers). BRAF somatic mutations have been identified in 50-70% of malignant melanomas, where all mutations are within the kinase domain and a single substitution (V600E) accounts for 80% of mutations. Activating BRAF mutations have also been documented in a variety of human cancers, including colorectal cancer (-10%), NSCLC (2-3%), and thyroid cancer (-36%). The high frequency of mutations makes targeting this pathway a strategy for cancer therapy. Accordingly, there is a large unmet medical need for improved therapies in these diseases especially in the advanced, refractory setting.

[0012] Provided herein are compounds that can inhibit the kinase activity of ERKl and/or the kinase activity of ERK2. The compounds described herein can also inhibit the phosphorylation of ERKl and ERK2, and thus can be ERK inhibitors (for example, ERKl inhibitors and/or ERK2 inhibitors). The compounds described herein may also effectively inhibit MAPK signaling through a dual mechanism, via inhibiting both the phosphorylation and activation of ERK by MEK, in addition to inhibiting ERK phosphorylation of RSK. As ERK inhibitors, the compounds described herein can be used to ameliorate and/or treat a variety of cancers, such as, lung cancer, pancreatic cancer, colon cancer, myeloid leukemia, thyroid cancer, myelodysplastic syndrome (MDS), bladder carcinoma, epidermal carcinoma, melanoma, breast cancer, prostate cancer, head and neck cancer, ovarian cancer, brain cancer, cancer of mesenchymal origin, sarcoma, tetracarcinoma, neuroblastoma, kidney carcinoma, hepatoma, non-Hodgkin's lymphoma, multiple myeloma and anaplastic thyroid carcinoma. Definitions

[0013] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

[0014] As used herein, any "R", "Y" or "Z" group(s) such as, without limitation, R ¹ , R ² , R ³ , R ⁴ , R ⁵ , R ⁶ , R ⁷ , R ⁸ , R ⁹ , R ¹⁰ , R ¹¹ , R ¹² , R ¹³ , Y ¹ , Y ² , Y ³ , Y ⁴ , Y ⁵ , Y ⁶ , Y ⁷ , Y ⁸ , Y ⁹ ' Y ¹⁰ and Z ¹ represent substituents that can be attached to the indicated atom. Such R, Y and/or Z groups may be referred to herein in a general way as "R" groups. An R group may be substituted or unsubstituted. If two "R" groups are described as being "taken together" the R groups and the atoms they are attached to can form a cycloalkyl, cycloalkenyl, aryl, heteroaryl or heterocycle. For example, without limitation, if R ^a and R ^b of an NR ^a R ^b group are indicated to be "taken together," it means that they are covalently bonded to one another to form a ring:

In addition, if two "R" groups are described as being "taken together" with the atom(s) to which they are attached to form a ring as an alternative, the R groups are not limited to the variables or substituents defined previously.

[0015] Whenever a group is described as being "optionally substituted" that group may be unsubstituted or substituted with one or more of the indicated substituents. Likewise, when a group is described as being "unsubstituted or substituted" if substituted, the substituent(s) may be selected from one or more of the indicated substituents. If no substituents are indicated, it is meant that the indicated "optionally substituted" or "substituted" group may be substituted with one or more group(s) individually and independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, acylalkyl, hydroxy, alkoxy, alkoxyalkyl, aminoalkyl, amino acid, aryl, heteroaryl, heterocyclyl, aryl(alkyl), heteroaryl(alkyl), heterocyclyl(alkyl), hydroxyalkyl, acyl, cyano, halogen, thiocarbonyl, O-carbamyl, N-carbamyl, O-thiocarbamyl, N-thiocarbamyl, C-amido, N-amido, S-sulfonamido, N-sulfonamido, C-carboxy, O-carboxy, isocyanato, thiocyanato, isothiocyanato, azido, nitro, silyl, sulfenyl, sulfinyl, sulfonyl, haloalkyl, haloalkoxy, trihalomethanesulfonyl, trihalomethanesulfonamido, an amino, a mono-substituted amino group and a di-substituted amino group.

That is, the alkyl, alkenyl, alkynyl, ring(s) of the cycloalkyl, ring(s) of the cycloalkenyl, ring(s) of the aryl, ring(s) of the heteroaryl or ring(s) of the heteroalicyclyl can contain from "a" to "b", inclusive, carbon atoms. Thus, for example, a "Ci to C ₄ alkyl" group refers to all alkyl groups having from 1 to 4 carbons, that is, CH ₃ -, CH ₃ CH ₂ -, CH ₃ CH ₂ CH ₂ -, (CH ₃ ) ₂ CH-, CH ₃ CH ₂ CH ₂ CH ₂ -, CH ₃ CH ₂ CH(CH ₃ )- and (CH ₃ ) ₃ C-. If no "a" and "b" are designated with regard to an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, heteroaryl or heteroalicyclyl group, the broadest range described in these definitions is to be assumed.

[0017] As used herein, "alkyl" refers to a straight or branched hydrocarbon chain that comprises a fully saturated (no double or triple bonds) hydrocarbon group. The alkyl group may have 1 to 20 carbon atoms (whenever it appears herein, a numerical range such as "1 to 20" refers to each integer in the given range; e.g., "1 to 20 carbon atoms" means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 20 carbon atoms, although the present definition also covers the occurrence of the term "alkyl" where no numerical range is designated). The alkyl group may also be a medium size alkyl having 1 to 10 carbon atoms. The alkyl group could also be a lower alkyl having 1 to 6 carbon atoms. The alkyl group of the compounds may be designated as "Ci-C ₄ alkyl" or similar designations. By way of example only, "Ci-C ₄ alkyl" indicates that there are one to four carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, and t-butyl. Typical alkyl groups include, but are in no way limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl and hexyl. The alkyl group may be substituted or unsubstituted.

Pharmaceutical Compositions

[0165] Some embodiments described herein relate to a pharmaceutical composition, that can include an effective amount of one or more compounds described herein (e.g., a compound of Formulae (I), (Π) or (ΠΙ), or a pharmaceutically acceptable salt thereof) and a pharmaceutically acceptable carrier, diluent, excipient or combination thereof.

[0166] The term "pharmaceutical composition" refers to a mixture of one or more compounds disclosed herein with other chemical components, such as diluents or carriers. The pharmaceutical composition facilitates administration of the compound to an organism. Pharmaceutical compositions can also be obtained by reacting compounds with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, and salicylic acid. Pharmaceutical compositions will generally be tailored to the specific intended route of administration.

[0167] The term "physiologically acceptable" defines a carrier, diluent or excipient that does not abrogate the biological activity and properties of the compound nor cause appreciable damage or injury to an animal to which delivery of the composition is intended.

[0168] As used herein, a "carrier" refers to a compound that facilitates the incorporation of a compound into cells or tissues. For example, without limitation, dimethyl sulfoxide (DMSO) is a commonly utilized carrier that facilitates the uptake of many organic compounds into cells or tissues of a subject.

[0169] As used herein, a "diluent" refers to an ingredient in a pharmaceutical composition that lacks appreciable pharmacological activity but may be pharmaceutically necessary or desirable. For example, a diluent may be used to increase the bulk of a potent drug whose mass is too small for manufacture and/or administration. It may also be a liquid for the dissolution of a drug to be administered by injection, ingestion or inhalation. A common form of diluent in the art is a buffered aqueous solution such as, without limitation, phosphate buffered saline that mimics the pH and isotonicity of human blood.

[0170] As used herein, an "excipient" refers to an essentially inert substance that is added to a pharmaceutical composition to provide, without limitation, bulk, consistency, stability, binding ability, lubrication, disintegrating ability etc., to the composition. A "diluent" is a type of excipient.

[0171] The pharmaceutical compositions described herein can be administered to a human patient per se, or in pharmaceutical compositions where they are mixed with other active ingredients, as in combination therapy, or carriers, diluents, excipients or combinations thereof. Proper formulation is dependent upon the route of administration chosen. Techniques for formulation and administration of the compounds described herein are known to those skilled in the art.

[0172] The pharmaceutical compositions disclosed herein may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or tableting processes. Additionally, the active ingredients are contained in an amount effective to achieve its intended purpose. Many of the compounds used in the pharmaceutical combinations disclosed herein may be provided as salts with pharmaceutically compatible counterions.

[0173] Multiple techniques of administering a compound exist in the art including, but not limited to, oral, rectal, pulmonary, topical, aerosol, injection and parenteral delivery, including intramuscular, subcutaneous, intravenous, intramedullary injections, intrathecal, direct intraventricular, intraperitoneal, intranasal and intraocular injections.

[0174] One may also administer the compound in a local rather than systemic manner, for example, via injection or implantation of the compound directly into the affected area, often in a depot or sustained release formulation. Furthermore, one may administer the compound in a targeted drug delivery system, for example, in a liposome coated with a tissue-specific antibody. The liposomes will be targeted to and taken up selectively by the organ. For example, intranasal or pulmonary delivery to target a respiratory infection may be desirable.

[0175] As described herein, compounds of Formulae (I), (II) or (ΙΠ), or a pharmaceutically acceptable salt thereof, can be administered by a variety of methods. In some of the methods described herein, administration can be by injection, infusion and/or intravenous administration over the course of 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, 12 hours, 24 hours or longer, or any intermediate time. Other methods described herein can include oral, intravenous and/or intraperitoneal administration to a subject in need thereof, for example, to a subject to treat a cancer described herein responsive to an ERK inhibitor.

[0176] The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, may be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. Compositions that can include a compound described herein formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition.

[0183] The compound(s) of Formulae (I), (II) or (ΙΠ) or a pharmaceutically acceptable salt thereof, that can be used can be any of the embodiments described in the "Compounds" section above.

[0184] As used herein, a "subject" refers to an animal that is the object of treatment, observation or experiment. "Animal" includes cold- and warm-blooded vertebrates and invertebrates such as fish, shellfish, reptiles and, in particular, mammals. "Mammal" includes, without limitation, mice, rats, rabbits, guinea pigs, dogs, cats, sheep, goats, cows, horses, primates, such as monkeys, chimpanzees, and apes, and, in particular, humans. In some embodiments, the subject can be human. In some embodiments, the subject can be a child and/or an infant, for example, a child or infant. In other embodiments, the subject can be an adult.

[0185] As used herein, the terms "treat," "treating," "treatment," "therapeutic," and "therapy" do not necessarily mean total cure or abolition of the disease or condition. Any alleviation of any undesired signs or symptoms of a disease or condition, to any extent can be considered treatment and/or therapy. Furthermore, treatment may include acts that may worsen the subject's overall feeling of well-being or appearance, and may positively affect one or more symptoms or aspects of the disease while having effects on other aspects of the disease or on unrelated systems that may be considered undesireable.

[0186] The terms "therapeutically effective amount" and "effective amount" are used to indicate an amount of an active compound, or pharmaceutical agent, that elicits the biological or medicinal response indicated. For example, a therapeutically effective amount of compound can be the amount needed to treat, alleviate or ameliorate one or more symptoms or conditions of disease or prolong the survival of the subject being treated This response may occur in a tissue, system, animal or human and includes alleviation of the signs or symptoms of the disease being treated. Determination of an effective amount is well within the capability of those skilled in the art, in view of the disclosure provided herein.

[0187] For example, an effective amount of a compound, or radiation, is the amount that results in: (a) the reduction, alleviation or disappearance of one or more symptoms caused by the cancer, (b) the reduction of tumor size, (c) the elimination of the tumor, and/or (d) long-term disease stabilization (growth arrest) of the tumor. In the treatment of lung cancer (such as non-small cell lung cancer) a therapeutically effective amount is that amount that alleviates or eliminates cough, shortness of breath and/or pain. As another example, an effective amount, or a therapeutically effective amount of an ERK inhibitor is the amount which results in the reduction in ERK (ERKI and/or ERK2) activity and/or phosphorylation. The reduction in ERK activity are known to those skilled in the art and can be determined by the analysis of pharmacodynamic markers such as phosphorylated RSKI,2 and phosphorylated ERKI,2 and/or or gene expression profile (mRNA).

[0188] The therapeutically effective amount of the compounds disclosed herein required as a dose will depend on the route of administration, the type of animal, including human, being treated, and the physical characteristics of the specific animal under consideration. The dose can be tailored to achieve a desired effect, but will depend on such factors as weight, diet, concurrent medication and other factors which those skilled in the medical arts will recognize.

[0189] Various indicators for determining the effectiveness of a method for treating a cancer, are known to those skilled in the art. Example of suitable indicators include, but are not limited to, the reduction, alleviation or disappearance of one or more symptoms caused by the cancer, the reduction of tumor size, the elimination of the tumor, and/or long-term disease stabilization (growth arrest) of the tumor.

[0190] As will be readily apparent to one skilled in the art, the useful in vivo dosage to be administered and the particular mode of administration will vary depending upon the age, weight, the severity of the affliction, and mammalian species treated, the particular compounds employed, and the specific use for which these compounds are employed. The determination of effective dosage levels, that is the dosage levels necessary to achieve the desired result, can be accomplished by one skilled in the art using routine methods, for example, human clinical trials and in vitro studies.

[0191] The dosage may range broadly, depending upon the desired effects and the therapeutic indication. Alternatively, dosages may be based and calculated upon the surface area of the patient, as understood by those of skill in the art. Although the exact dosage will be determined on a drug-by-drug basis, in most cases, some generalizations regarding the dosage can be made. The daily dosage regimen for an adult human patient may be, for example, an oral dose of between 0.01 mg and 3000 mg of each active ingredient, preferably between 1 mg and 700 mg, e.g. 5 to 200 mg. The dosage may be a single one or a series of two or more given in the course of one or more days, as is needed by the subject. In some embodiments, the compounds will be administered for a period of continuous therapy, for example for a week or more, or for months or years.

[0192] In instances where human dosages for compounds have been established for at least some condition, those same dosages may be used, or dosages that are between about 0.1% and 500%, more preferably between about 25% and 250% of the established human dosage. Where no human dosage is established, as will be the case for newly- discovered pharmaceutical compositions, a suitable human dosage can be inferred from ED ₅₀ or ID ₅₀ values, or other appropriate values derived from in vitro or in vivo studies, as qualified by toxicity studies and efficacy studies in animals.

[0193] In cases of administration of a pharmaceutically acceptable salt, dosages may be calculated as the free base. As will be understood by those of skill in the art, in certain situations it may be necessary to administer the compounds disclosed herein in amounts that exceed, or even far exceed, the above-stated, preferred dosage range in order to effectively and aggressively treat particularly aggressive diseases or infections.

[0194] Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations. Dosage intervals can also be determined using MEC value. Compositions should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

[0195] It should be noted that the attending physician would know how to and when to terminate, interrupt, or adjust administration due to toxicity or organ dysfunctions. Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response were not adequate (precluding toxicity). The magnitude of an administrated dose in the management of the disorder of interest will vary with the severity of the condition to be treated and to the route of administration. The severity of the condition may, for example, be evaluated, in part, by standard prognostic evaluation methods. Further, the dose and perhaps dose frequency, will also vary according to the age, body weight, and response of the individual patient. A program comparable to that discussed above may be used in veterinary medicine.

[0196] Compounds disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound, or of a subset of the compounds, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds in an animal model, such as mice, rats, rabbits, or monkeys, may be determined using known methods. The efficacy of a particular compound may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, route of administration and/or regime.

Active ERK1 and ERK2 Kinase Assay

[0426] Activated ERK1 and ERK2 activity was determined in a Mobility Shift Assay (MSA) format as follows: Compound and kinase solution were prepared with assay buffer (20 mM HEPES, 0.01% Triton X-100, 2 mM DTT, pH7.5) and mixed and incubated in for 30 mins at rt . ERK1 & ERK2 were then activated by the addition of Fl-Substrate, ATP and metal solution and incubated for 1 h at rt . After 1 h, the reaction was terminated by the addition of 70 mL of Termination Buffer (QuickScout Screening Assist MSA; Carna Biosciences) to the well. The reaction mixture was applied to LabChip ™ system (PerkinElmer), and the product and substrate peptide peaks were separated, analyzed and quantitated. The kinase reaction is evaluated by the product ratio calculated from peak heights of product (P) and substrate(S) peptides (P/(P+S)).

[0427] Compounds of Formulae (I), (Π) and (ΠΙ) are active in this assay as indicated in Table 1, where A = a single IC ₅₀ ≤50 nM; B = a single IC ₅₀ >50 nM and < 250 nM; C = a single IC ₅₀ >250 nM.

ERK and RSK Target Engagement Biomarker (pERK and pRSK Western Blot) Protocols

[0428] BRAF mutant melanoma cells A375 are plated at approximately 1 x 106 cells per 10 cm dish in growth media (RPMI 1640, 10% FBS, non-essential amino acids and glutamine). The next day the media is removed and replaced with serum free media (RPMI 1640, 0.1% FBS, non-essential amino acids and glutamine) and allowed to incubate overnight. The following day the serum free media is removed and replaced with fresh serum free media containing compound. Typical concentrations for drug treatments are 300 nM, 100 nM, 30 nM, 10 nM, 3 nM and 1 nM, with a final DMSO concentration of 0.1%. The controls include one plate with DMSO alone at 0.1% final concentration and another plate treated with a compound control at 10 nM final concentration. The cells are treated for 24 h. At the time of harvest, the cells are scraped directly into the media and spun down at 1800 rpm in order to capture the floating dead or dying cells as well. One wash with 5 mL of PBS is done, and the cell pellet are frozen or lysed immediately in lysis buffer. The protein concentrations of the lysates are determined using the Pierce BCA protein assay kit and 50 μg of total cell lysate is loaded per lane of a 15 well, 1.5 mm width Tris glycine gel. The gels are run at 125 Volts constant voltage until the dye just runs off the gel. They are transferred using the Invitrogen transfer apparatus onto nitrocellulose membranes at 25 Volts for 2 h. The nitrocellulose membrane is blocked in 5% (wt/vol) non-fat dried milk protein in TBS/Tween for 30 mins at rt. The blot is incubated with anti-RSK or with anti-ERK antibodies. The nitrocellulose membrane is washed 3 times for 10 minutes with vigorous rocking in 50 mL TBS/Tween then incubated 1 h with HRPx-labeled secondary antibody at room temperature. The secondary antibodies are diluted in 2% non-fat dried milk protein in TBS/Tween.

[0429] The nitrocellulose is washed as above then developed with freshly prepared ECL reagent. The nitrocellulose membranes are incubated for 1 minute with 5 mL ECL reagent. Excess reagent is removed by blotting on a clean paper towel, and the membrane is wrapped in cellophane before exposing to film. Several exposures of film are made for each blot. (The western blots may be developed and/or quantitated by other means if available.) Band densities are quantitated by densitometry, and the scanned densities are plotted using XLfit to give dose response curves.

Proliferation Assay

[0430] A375 (melanoma), Colo-205 (colon cancer), Miapaca (pancreatic), HPAFII (pancreatic), sNF02.0 (neurofibromatosis type 1), sNF96.2 (neurofibromatosis type 1) and 8505 (Thyroid) cells were grown and maintained in RPMI-1640 medium containing 100 U/mL penicillin-streptomycin and 10% fetal bovine serum. Cells were in growth medium in 96-well opaque-walled clear bottom plates and incubated in the C0 ₂ incubator overnight before treatment. Cells were treated with compounds diluted in DMSO and a 10 point 3-fold serial dilutions were done. Plates were placed in 37°C, 5% C0 ₂ to incubate for 3 days. Before they were developed by adding 100 μΐ _^ of CellTiter-Glo reagent (Promega) to the assay plate, plates were shaken briefly for 2 mins and allowed to incubate at room temperature for 10 mins. The bottom of the plates was pasted with white back seal and luminescence was recorded with Flexstation3 with setting of luminescence, integration time 500 ms.

[0431] Compounds of Formula (I), (Π) and (ΙΠ) are active in this assay as noted in Table 2. In Table 2: A = a single IC ₅₀ <500 nM; B = a single IC ₅₀ >500 nM and < 1.0 μΜ; C = a single IC ₅₀ >1.0 μΜ.
