Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, alcohols (e.g., methanol, ethanol, iso-propanol, or butanol) or acetonitrile (ACN) are preferred.

    [0360] Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by reference in its entirety.

    Synthesis

    [0361] As will be appreciated by those skilled in the art, the compounds provided herein, including salts and stereoisomers thereof, can be prepared using known organic synthesis techniques and can be synthesized according to any of numerous possible synthetic routes.

    [0362] Compounds of Formula I provided herein can be prepared as shown in Scheme 1 (e.g., compounds of formula 1-17 in Scheme 1). Suitable starting materials 1-1, where Y.sup.1 is a halogen (e.g., Cl, Br, or I) or pseudohalogen (e.g., OTf or OMs) and P.sup.1 is a suitable protecting group (e.g., SO.sub.2Ph or SEM), can be protected as acetal 1-2 under standard conditions (e.g., in the presence of MeOH and AcCl). Acetal 1-2 can be converted to dihalide 1-3, where Y.sup.2 is a halogen (e.g., Cl, Br, or I), under standard conditions (e.g., in the presence of LDA or alkyllithium, and 1,2-dibromotetrachloroethane in the case of bromination). Halide 1-3 can be coupled with substituted metal 1-4 (e.g., M.sup.1 is B(OH).sub.2, Bpin, BF.sub.3K, Sn(Bu).sub.3, or Zn) under standard Suzuki coupling conditions (e.g., in the presence of a palladium catalyst, such as tetrakis(triphenylphosphine)palladium(O), dichlorobis(triphenylphosphine)palladium(II), or [1,1-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane and a base (e.g., a carbonate base, such as sodium carbonate or potassium carbonate)) or standard Stille coupling conditions (e.g., in the presence of a palladium(O) catalyst, such as tetrakis(triphenylphosphine)palladium(O)) or standard Negishi coupling conditions (e.g., in the presence of a palladium(O) catalyst, such as tetrakis(triphenylphosphine)palladium(O) or [1,1-bis(diphenylphosphino)ferrocene]dichloropalladium(II)) to afford compound 1-5.

Imine 1-13 can be converted to intermediate 1-14 under standard conditions (e.g., in the presence of NaBH.sub.4, Na(OAc).sub.3BH or NaBH.sub.3CN). Removal of the protecting group P.sup.2 from intermediate 1-14 under conditions suitable for the protecting group chosen (e.g., HCl for P.sup.2=SOt-Bu) affords diamine 1-15. Diamine 1-15 can be converted to cyclic urea 1-16 under standard conditions (e.g., in the presence of CDI).

Diamine 2-3 can be converted to cyclic urea 2-4 under standard conditions (e.g., in the presence of CDI). Cyclic urea 2-4 can be converted to pyrimidinone 2-5 under standard conditions (e.g., in the presence of DDQ). Removal of the protecting group P.sup.1 from intermediate 2-5 under conditions suitable for the protecting group chosen (e.g., NaOH for P.sup.1?SO.sub.2Ph; or TFA followed by ethylenediamine for P.sup.1=SEM) affords compounds of 2-6.

    ##STR00028##

    [0365] Compounds of Formula I can also be prepared, for example, as shown in Scheme 3 (e.g., compounds of formula 3-8 in Scheme 3). Intermediate 2-2, as described in Scheme 2, can be converted to intermediate 3-1 under standard conditions (e.g., in the presence of MnO.sub.2).

Imine 3-3 can be converted to intermediate 3-5 under standard conditions (e.g., in the presence of organometallic species 3-4 (e.g., M.sup.t is Li or Mg)). Removal of the protecting group P.sup.2 from intermediate 3-5 under conditions suitable for the protecting group chosen (e.g., HCl for P.sup.2=SOt-Bu) affords diamine 3-6. Diamine 3-6 can be converted to cyclic urea 3-7 under standard conditions (e.g., in the presence of CDI).

    [0367] One skilled in the art would recognize that the steps of Scheme 4 can be performed in different orders (e.g., if desired and reactivity of the reagents and intermediates permit, the position of R.sup.3 can be functionalized before R.sup.2 is functionalized).

    [0368] Compounds of Formula I can also be prepared, for example, as shown in Scheme 5 (e.g., compounds of formula 5-6 in Scheme 5). Intermediate 4-9, as described in Scheme 4, can be converted to carboxylic acid 5-1 under standard conditions (e.g., in the presence of a base such as sodium hydroxide or lithium hydroxide).

    [0369] The reactions for preparing compounds described herein can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants), the intermediates, or products at the temperatures at which the reactions are carried out, (e.g., temperatures which can range from the solvent's freezing temperature to the solvent's boiling temperature). A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan.

    [0370] The expressions, ambient temperature or room temperature, or rt as used herein, are understood in the art, and refer generally to a temperature, e.g., a reaction temperature, that is about the temperature of the room in which the reaction is carried out, for example, a temperature from about 20? C. to about 30? C.

    [0371] Preparation of compounds described herein can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3.sup.rd Ed., Wiley & Sons, Inc., New York (1999).

    [0372] Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., .sup.1H or .sup.13C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), mass spectrometry, or by chromatographic methods such as high performance liquid chromatography (HPLC), liquid chromatography-mass spectroscopy (LCMS), or thin layer chromatography (TLC). Compounds can be purified by those skilled in the art by a variety of methods, including high performance liquid chromatography (HPLC) and normal phase silica chromatography.

    Methods of Use

    [0373] The compounds described herein can inhibit the activity of the V617F variant of the protein-tyrosine kinase JAK2 (i.e., V617F or JAK2V617F). Compounds which inhibit V617F are useful in providing a means of preventing the growth or inducing apoptosis in tumors, particularly by inhibiting angiogenesis. It is therefore anticipated that the compounds of the disclosure are useful in treating or preventing proliferative disorders such as cancers. In particular tumors with activating mutants of receptor tyrosine kinases or upregulation of receptor tyrosine kinases may be particularly sensitive to the inhibitors.

    [0374] In certain embodiments, the present disclosure provides a method for treating a V617F-related disorder in a patient in need thereof, comprising the step of administering to said patient a compound of the disclosure, or a pharmaceutically acceptable composition thereof.

    [0375] Myeloproliferative diseases (MPD) are multipotent hematopoietic stem cell disorders characterized by excess production of various blood cells. MPNs include polycythemia vera (PV), essential thrombocythemia (ET), and idiopathic myelofibrosis (IMF). JAK2 V617F mutation is reported in about 95% of patients with PV, in 35% to 70% of patients with ET, and 50% of patients with IMF. Also, JAK2 exon 12 mutations are detected in some of the V617F-negative PV patients (Ma et al., J. Mol. Diagn., 11: 49-53, 2009). In some embodiments, the compounds of the disclosure can be useful in the treatment of myeloproliferative disorders (e.g., myeloproliferative neoplasms) in a patient in need thereof, such as polycythemia vera, essential thrombocythemia, myelofibrosis with myeloid metaplasia (MMM), primary myelofibrosis (PMF), chronic myelogenous leukemia (CML), chronic myelomonocytic leukemia (CMML), hypereosinophilic syndrome (HES), systemic mast cell disease (SMCD), and the like.

    [0376] In some embodiments, the myeloproliferative disorder is a myeloproliferative neoplasm.

    [0377] In some embodiments, the myeloproliferative disorder is myelofibrosis (e.g., primary myelofibrosis (PMF) or post polycythemia vera/essential thrombocythemia myelofibrosis (Post-PV/ET MF)).

    [0378] In some embodiments, the myeloproliferative disorder is primary myelofibrosis (PMF).

    [0381] In some embodiments, the myeloproliferative disorder is selected from primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocythemia (ET).

    [0382] In some embodiments, the myeloproliferative neoplasm is primary myelofibrosis (PMF).

    [0383] In some embodiments, the myeloproliferative neoplasm is polycythemia vera (PV).

    [0384] In some embodiments, the myeloproliferative neoplasm is essential thrombocythemia (ET).

    [0385] Myeloproliferative diseases include disorders of a bone marrow or lymph node-derived cell type, such as a white blood cell. A myeloproliferative disease can manifest by abnormal cell division resulting in an abnormal level of a particular hematological cell population. The abnormal cell division underlying a proliferative hematological disorder is typically inherent in the cells and not a normal physiological response to infection or inflammation. Leukemia is a type of myeloproliferative disease. Exemplary myeloproliferative diseases include, but are not limited to, acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), myelodysplastic syndrome (MDS), chronic myeloid leukemia (CMIL), hairy cell leukemia, leukemic manifestations of lymphomas, multiple myeloma, polycythemia vera (PV), essential thrombocythemia (ET), idiopathic myelofibrosis (IMF), hypereosinophilic syndrome (HES), chronic neutrophilic leukemia (CNL), myelofibrosis with myeloid metaplasia (MMM), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia, chronic basophilic leukemia, chronic eosinophilic leukemia, systemic mastocytosis (SM), and unclassified myeloproliferative diseases (UMPD or MPD-NC). Lymphoma is a type of proliferative disease that mainly involves lymphoid organs, such as lymph nodes, liver, and spleen. Exemplary proliferative lymphoid disorders include lymphocytic lymphoma (also called chronic lymphocytic leukemia), follicular lymphoma, large cell lymphoma, Burkitt's lymphoma, marginal zone lymphoma, lymphoblastic lymphoma (also called acute lymphoblastic lymphoma).

    [0386] For example, the compounds of the disclosure are useful in the treatment of cancer. Example cancers include bladder cancer (e.g., urothelial carcinoma, squamous cell carcinoma, adenocarcinoma), breast cancer (e.g., hormone R positive, triple negative), cervical cancer, colorectal cancer, cancer of the small intestine, colon cancer, rectal cancer, cancer of the anus, endometrial cancer, gastric cancer (e.g., gastrointestinal stromal tumors), head and neck cancer (e.g., cancers of the larynx, hypopharynx, nasopharynx, oropharynx, lips, and mouth, squamous head and neck cancers), kidney cancer (e.g., renal cell carcinoma, urothelial carcinoma, sarcoma, Wilms tumor), liver cancer (e.g., hepatocellular carcinoma, cholangiocellular carcinoma (e.g., intrahepatic, hilar or perihilar, distal extrahepatic), liver angiosarcoma, hepatoblastoma), lung cancer (e.g., adenocarcinoma, small cell lung cancer and non-small cell lung carcinomas, parvicellular and non-parvicellular carcinoma, bronchial carcinoma, bronchial adenoma, pleuropulmonary blastoma), ovarian cancer, prostate cancer, testicular cancer, uterine cancer, vulvar cancer, esophageal cancer, gall bladder cancer, pancreatic cancer (e.g. exocrine pancreatic carcinoma), stomach cancer, thyroid cancer, parathyroid cancer, neuroendocrine cancer (e.g., pheochromocytoma, Merkel cell cancer, neuroendocrine carcinoma), skin cancer (e.g., squamous cell carcinoma, Kaposi sarcoma, Merkel cell skin cancer), and brain cancer (e.g., astrocytoma, medulloblastoma, ependymoma, neuro-ectodermal tumors, pineal tumors).

    [0387] Further example cancers include hematopoietic malignancies such as leukemia or lymphoma, multiple myeloma, chronic lymphocytic lymphoma, adult T cell leukemia, acute myeloid leukemia (AML), B-cell lymphoma, cutaneous T-cell lymphoma, acute myelogenous leukemia, Hodgkin's or non-Hodgkin's lymphoma, myeloproliferative neoplasms (e.g., 8p11 myeloproliferative syndrome, polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF)), myelodysplastic syndrome, chronic eosinophilic leukemia, Waldenstrom's Macroglubulinemia, hairy cell lymphoma, chronic myelogenic lymphoma, acute lymphoblastic lymphoma, AIDS-related lymphomas, and Burkitt's lymphoma.

    [0388] In certain embodiments, provided herein is a method of treating cancer comprising administering to a patient in need thereof a therapeutically effect amount of a compound of the disclosure. In certain embodiments, the cancer is selected from T lymphoblastic lymphoma, glioblastoma, melanoma, rhabdosarcoma, lymphosarcoma, and osteosarcoma.

    [0389] Other cancers treatable with the compounds of the disclosure include tumors of the eye, glioblastoma, melanoma, leiomyosarcoma, and urothelial carcinoma (e.g., ureter, urethra, bladder, urachus).

    [0390] The compounds of the disclosure can also be useful in the inhibition of tumor metastases.

    [0391] In some embodiments, the compounds of the disclosure as described herein can be used to treat Alzheimer's disease, HIV, or tuberculosis.

    [0392] In some embodiments, the compounds of the disclosure can be useful in the treatment of myelodysplastic syndrome (MDS) in a patient in need thereof. In some embodiments, said patient having the myelodysplastic syndrome (MDS) is red blood cell transfusion dependent.

    [0393] As used herein, myelodysplastic syndromes are intended to encompass heterogeneous and clonal hematopoietic disorders that are characterized by ineffective hematopoiesis on one or more of the major myeloid cell lineages. Myelodysplastic syndromes are associated with bone marrow failure, peripheral blood cytopenias, and a propensity to progress to acute myeloid leukemia (AML). Moreover, clonal cytogenetic abnormalities can be detected in about 50% of cases with MDS. In 1997, The World Health Organization (WHO) in conjunction with the Society for Hematopathology (SH) and the European Association of Hematopathology (EAHP) proposed new classifications for hematopoietic neoplasms (Harris, et al., J Clin Oncol 1999; 17:3835-3849; Vardiman, et al., Blood 2002; 100:2292-2302). For MDS, the WHO utilized not only the morphologic criteria from the French-American-British (FAB) classification but also incorporated available genetic, biologic, and clinical characteristics to define subsets of MDS (Bennett, et al., Br. J. Haematol. 1982; 51:189-199). In 2008, the WHO classification of MDS (Table 1) was further refined to allow precise and prognostically relevant subclassification of unilineage dysplasia by incorporating new clinical and scientific information (Vardiman, et al., Blood 2009; 114:937-951; Swerdlow, et al., WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues. 4th Edition. Lyon France: IARC Press; 2008:88-103; Bunning and Germing, Myelodysplastic syndromes/neoplasms in Chapter 5, Swerdlow, et al, eds. WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues. (ed. 4th edition): Lyon, France: IARC Press; 2008:88-103).

Nos. 9,233,985, 10,065,974, 10,287,303, 8,524,867, the disclosures of which are incorporated by reference herein in their entireties).

    [0465] Methods for the safe and effective administration of most of these chemotherapeutic agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the Physicians' Desk Reference (PDR, e.g., 1996 edition, Medical Economics Company, Montvale, NJ), the disclosure of which is incorporated herein by reference as if set forth in its entirety.

    [0466] As provided throughout, the additional compounds, inhibitors, agents, etc. can be combined with the present compound in a single or continuous dosage form, or they can be administered simultaneously or sequentially as separate dosage forms.

    Pharmaceutical Formulations and Dosage Forms

    [0467] When employed as pharmaceuticals, the compounds of the disclosure can be administered in the form of pharmaceutical compositions. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration may be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral, or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable.

    [0468] This disclosure also includes pharmaceutical compositions which contain, as the active ingredient, the compound of the disclosure or a pharmaceutically acceptable salt thereof, in combination with one or more pharmaceutically acceptable carriers (excipients). In some embodiments, the composition is suitable for topical administration. In making the compositions of the disclosure, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.

    [0469] In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh.

    [0470] The compounds of the disclosure may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the disclosure can be prepared by processes known in the art, e.g., see International App. No. WO 2002/000196.

    [0471] Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.

    [0472] The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1000 mg (1 g), more usually about 100 to about 500 mg, of the active ingredient. The term unit dosage forms refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

    [0473] In some embodiments, the compositions of the disclosure contain from about 5 to about 50 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 5 to about 10, about 10 to about 15, about 15 to about 20, about 20 to about 25, about 25 to about 30, about 30 to about 35, about 35 to about 40, about 40 to about 45, or about 45 to about 50 mg of the active ingredient.

    [0474] In some embodiments, the compositions of the disclosure contain from about 50 to about 500 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 50 to about 100, about 100 to about 150, about 150 to about 200, about 200 to about 250, about 250 to about 300, about 350 to about 400, or about 450 to about 500 mg of the active ingredient.

    [0475] In some embodiments, the compositions of the disclosure contain from about 500 to about 1000 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 500 to about 550, about 550 to about 600, about 600 to about 650, about 650 to about 700, about 700 to about 750, about 750 to about 800, about 800 to about 850, about 850 to about 900, about 900 to about 950, or about 950 to about 1000 mg of the active ingredient.

    [0476] Similar dosages may be used of the compounds described herein in the methods and uses of the disclosure.

    [0477] The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

    [0478] For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, about 0.1 to about 1000 mg of the active ingredient of the present disclosure.

    [0479] The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

    [0480] The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

    [0481] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect.

    [0482] Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

    [0483] Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g. glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, for example, glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, for example, 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.

    [0484] The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.

    [0485] The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.

    [0486] The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 ?g/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

    [0487] The compositions of the disclosure can further include one or more additional pharmaceutical agents such as a chemotherapeutic, steroid, anti-inflammatory compound, or immunosuppressant, examples of which are listed herein.

    Labeled Compounds and Assay Methods

    [0488] Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating V617F in tissue samples, including human, and for identifying V617F inhibitors by binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion.) Accordingly, the present disclosure includes V617F assays that contain such labeled or substituted compounds.

    [0489] The present disclosure further includes isotopically-labeled compounds of the disclosure. An isotopically or radio-labeled compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to .sup.2H (also written as D for deuterium), .sup.3H (also written as T for tritium), .sup.11C, .sup.13C, .sup.14C, .sup.13N, .sup.15N, .sup.15O, .sup.17O, .sup.18O, 18F, .sup.35S, .sup.36Cl, .sup.82Br, .sup.75Br, .sup.76Br, .sup.77Br, .sup.123I, .sup.124I, .sup.125I and .sup.131I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C.sub.1-6 alkyl group of Formula I can be optionally substituted with deuterium atoms, such as CD.sub.3 (i.e., trideuteromethyl) being substituted for CH.sub.3). In some embodiments, alkyl groups of the disclosed Formulas (e.g., Formula I, Formula Ia, etc.) can be perdeuterated.

    [0490] One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a C.sub.1-6 alkyl group can be replaced by deuterium atoms, such as CD.sub.3 being substituted for CH.sub.3). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1-2, 1-3, 1-4, 1-5, 1-6, 1-8, 1-10, 1-12, 1-14, 1-16, 1-18, or 1-20 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms.

    [0491] In some embodiments, each hydrogen atom of the compounds provided herein, such as hydrogen atoms attached to carbon atoms of alkyl, alkoxy, phenyl, and indazolyl substituents, as described herein, is optionally replaced by deuterium atoms.

    [0492] In some embodiments, each hydrogen atom of the compounds provided herein, such as hydrogen atoms to carbon atoms of alkyl, alkoxy, phenyl, and indazolyl substituents, as described herein, is replaced by deuterium atoms (i.e., the alkyl, alkoxy, phenyl, and indazolyl substituents are perdeuterated).

    [0493] In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 hydrogen atoms, attached to carbon atoms of alkyl, alkoxy, phenyl, and indazolyl substituents, as described herein, are optionally replaced by deuterium atoms.

    [0494] In some embodiments, 1, 2, 3, 4, 5, 6, 7, or 8 hydrogen atoms, attached to carbon atoms of alkyl, alkoxy, phenyl, and indazolyl substituents, as described herein, are optionally replaced by deuterium atoms.

    [0495] In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-Vd), or a pharmaceutically acceptable salt thereof, comprises at least one deuterium atom.

    [0496] In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-Vd), or a pharmaceutically acceptable salt thereof, comprises two or more deuterium atoms.

    [0497] In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-Vd), or a pharmaceutically acceptable salt thereof, comprises three or more deuterium atoms.

    [0498] In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-Vd), or a pharmaceutically acceptable salt thereof, comprises three to nine deuterium atoms.

    [0499] In some embodiments, for a compound provided herein (e.g., the compound of any of Formulas I-Vd), or a pharmaceutically acceptable salt thereof, all of the hydrogen atoms are replaced by deuterium atoms (i.e., the compound is perdeuterated).

    [0500] Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

    [0501] Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. (see e.g., A. Kerekes et. al. J. Med. Chem. 2011, 54, 201-210; R. Xu et. al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.

    [0502] The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro V617F labeling and competition assays, compounds that incorporate .sup.3H, .sup.14C, .sup.82Br, .sup.125I, .sup.131I or .sup.35S can be useful. For radio-imaging applications .sup.11C, .sup.18F, .sup.125I, .sup.123I, .sup.124I, .sup.131I, .sup.75Br, .sup.76Br or .sup.77Br can be useful.

    [0503] It is understood that a radio-labeled or labeled compound is a compound that has incorporated at least one radionuclide. In some embodiments, the radionuclide is selected from the group consisting of .sup.3H, .sup.14C, .sup.125I, .sup.35S and .sup.82Br.

    [0504] The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.

    [0505] A labeled compound of the disclosure can be used in a screening assay to identify/evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind V617F by monitoring its concentration variation when contacting with V617F, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to V617F (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to V617F directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

    Kits

    [0506] The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of V617F-associated diseases or disorders as described herein, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

    [0507] The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results.

    EXAMPLES

    [0508] Preparatory LC-MS purifications of some of the compounds prepared were performed on Waters mass directed fractionation systems. The basic equipment setup, protocols, and control software for the operation of these systems have been described in detail in the literature (see e.g. Two-Pump At Column Dilution Configuration for Preparative LC-MS, K. Blom, J. Combi. Chem., 4, 295 (2002); Optimizing Preparative LC-MS Configurations and Methods for Parallel Synthesis Purification, K. Blom, R. Sparks, J. Doughty, G. Everlof, T. Haque, A. Combs, J.

    [0510] Some of the compounds prepared were also separated on a preparative scale by reverse-phase high performance liquid chromatography (RP-HPLC) with MS detector or flash chromatography (silica gel) as indicated in the Examples. Typical preparative reverse-phase high performance liquid chromatography (RP-HPLC) column conditions are as follows:

C.sub.18 5 ?m, 30?100 mm column, eluting with mobile phase A: 0.1% NH.sub.4OH in water and mobile phase B: acetonitrile; the flow rate was 60 mL/minute, the separating gradient was optimized for each compound using the Compound Specific Method Optimization protocol as described in the literature (see e.g., Preparative LCMS Purification: Improved Compound Specific Method Optimization, K. Blom, B. Glass, R. Sparks, A. Combs, J. Comb. Chem., 6, 874-883 (2004)).
