Abstract
Description
[Technical Field]
[0001] Background of the Invention The present invention had the object of finding new compounds with valuable properties, in particular new compounds that can be used for the preparation of medicines.
[0002] The present invention relates to 4-(imidazo[1,2-a]pyridin-3-yl)-pyrimidine derivatives that inhibit c-KIT across a wide range of c-KIT kinase mutations and secondary mutations (secondary resistance mutation V654A in exon 13) that can occur in patients with GIST (gastrointestinal stromal tumor). The compounds of the present invention are therefore useful for treating diseases such as cancer. The present invention also provides methods for preparing these compounds, pharmaceutical compositions containing these compounds, compounds for use in treating diseases, and methods for treating diseases using pharmaceutical compositions containing these compounds. Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal (GI) tract.
[0003] c-KIT is a type III receptor tyrosine kinase that plays an important role in the occurrence of cancer. Mutant forms of the receptor tyrosine kinase c-KIT are drivers of several cancers, such as GIST, SM (systemic mastocytosis), some types of AML, and melanoma, and are therefore attractive targets for therapy. Gain-of-function mutations in KIT play an important role in the pathogenesis of gastrointestinal tumors (GIST).
[0004] GISTs are defined as mesenchymal spindle cell or epithelioid neoplasms that are c-KIT (CD117, stem cell factor receptor) positive. GISTs commonly harbor primary activating mutations in the KIT gene (90%), which lead to ligand-independent activation of the receptor tyrosine kinase c-KIT, making the tumor dependent on oncogenic KIT activity.
[0005] Although benefit is seen from the use of inhibitors of KIT kinase activity (e.g., imatinib), particularly in GIST, primary resistance occurs in association with certain oncogenic mutations. Furthermore, resistance frequently arises due to secondary mutations (L.K. Ashman & R. Griffith (2013) Expert Opinion on Investigational Drugs, 22:1, 103-115). Treatment of GIST with primary mutations with imatinib has an initial response rate of ~70%, but acquired resistance has been reported to develop in 40-50% of cases within an average of 2 years. The secondary mutation V654A in exon 13 is the most frequent resistance mutation after imatinib treatment.
[0006] L C Chen et al. describe "A Missense Mutation in KIT kinase domain 1 correlates with imatinib resistance in gastrointestinal stromal tumors" in Cancer Res. 2004;64:5913-5919. K G Roberts et al. describe "Resistance to c-KIT kinase inhibitors conferred by V654A mutation" in Mol. Cancer Ther. 2007;6:1159-1166. There is a large unmet medical need for the development of safe and specific inhibitors for the KIT V654A resistance mutation.
[0007] The compounds according to the invention and their salts have been found to possess highly valuable pharmacological properties whilst being well tolerated. The present invention specifically relates to compounds of formula I that inhibit c-KIT kinase, preferably the V654A mutant of c-KIT kinase.
[0008] Furthermore, the compound of formula I inhibits PDGFRα(V651D). Gain-of-function mutations of PDGFRα appear to play an important role in the development of GISTs lacking KIT mutations (S. Hirota et al., Gastroenterology 2003;125:660-667).
[0009] The host or patient may belong to any mammalian species, for example, primates, particularly humans; rodents, including mice, rats, and hamsters; rabbits; horses, cows, dogs, cats, etc. Animal models are objects for experimental investigation and provide models for the treatment of human diseases.
[0010] The sensitivity of specific cells to treatment with the compounds of the present invention can be determined by in vitro testing. Typically, cell cultures are combined with various concentrations of the compounds of the present invention for a period of time (usually between about 1 hour and 1 week) sufficient for the active agent, such as anti-IgM, to induce a cellular response, such as the expression of surface markers. In vitro testing can be performed using cells cultured from blood or biopsy samples. The amount of expressed surface markers is assessed by flow cytometry using specific antibodies that recognize the markers.
[0011] Doses will vary depending on the particular compound used, the particular disease, the patient's condition, etc. A therapeutic dose is typically sufficient to substantially reduce the undesirable cell population in the target tissue while maintaining patient viability. Treatment is generally continued until a substantial reduction has occurred, e.g., at least about a 50% reduction in cell burden, and may be continued until the undesirable cells are essentially undetectable in the body.
[0012] prior art WO 2010 / 009155 discloses other fused heterocyclic compounds as inhibitors of histone deacetylases and / or cyclin-dependent kinases. WO 2011 / 076419 discloses imidazopyridines as inhibitors of JAK kinases. Summary of the Invention

[0080] Particularly preferred are the hydrochloride, dihydrochloride, hydrobromide, maleate, mesylate, phosphate, sulfate, and succinate salts.
[0081] Acid addition salts of basic compounds of Formula I are prepared in the conventional manner by contacting the free base form with a sufficient amount of the desired acid to cause the formation of the salt. The free base can be regenerated in the conventional manner by contacting the salt form with a base and isolating the free base. The free base forms differ in certain respects from their corresponding salt forms with respect to certain physical properties, such as solubility in polar solvents; however, for purposes of this invention, the salts otherwise correspond to their respective free base forms.
[0082] As mentioned, pharmaceutically acceptable base addition salts of the compounds of formula I are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Preferred metals are sodium, potassium, magnesium, and calcium.

[0083] The base addition salts of acidic compounds according to the invention are prepared in the conventional manner by contacting the free acid form with a sufficient amount of the desired base to cause the formation of the salt. The free acid can be regenerated in the conventional manner by contacting the salt form with an acid and isolating the free acid. The free acid forms differ in certain respects from their corresponding salt forms with respect to certain physical properties, such as solubility in polar solvents; however, for purposes of this invention, the salts otherwise correspond to their respective free acid forms.
[0084] If the compound according to the present invention contains more than one group capable of forming pharmaceutically acceptable salts of this type, the present invention also encompasses multiple salts. Typical multiple salt forms include, for example, bitartrate, diacetate, difumarate, dimeglumine, diphosphate, disodium, and trihydrochloride, but this is not intended to represent a limitation.
[0085] As defined above, it is understood that the expression "pharmaceutically acceptable salt" in this context is to be understood as meaning an active ingredient comprising a compound of formula I in the form of one of its salts, especially if this salt form confers improved pharmacokinetic properties on the active ingredient compared to the free form of the active ingredient or any other salt form of the active ingredient previously used. A pharmaceutically acceptable salt form of an active ingredient can also confer on this active ingredient for the first time desired pharmacokinetic properties that it did not previously possess, and can even have a positive effect on the pharmacodynamics of this active ingredient with regard to its therapeutic effect in the body.
[0086] Isotopes Furthermore, compounds of Formula I are intended to encompass isotopically labeled forms thereof. Isotopically labeled forms of compounds of Formula I are identical to the compound except for the fact that one or more atoms of the compound have been replaced by an atom or atoms having an atomic mass or mass number different from the atomic mass or mass number of most naturally occurring atoms. Examples of isotopes that are readily commercially available and that can be incorporated into compounds of Formula I by well-known methods include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, and chlorine, e.g., 2 H, 3 H, 13 C. 14 C. 15 N, 18 O. 17 O. 31 P, 32 P, 35 S, 18 F, and 36 CI, respectively. Compounds of Formula I, prodrugs thereof, or pharmaceutically acceptable salts of either, that contain one or more of the above isotopes and / or other isotopes of other atoms are intended to be part of the present invention. Isotopically labeled compounds of Formula I can be used in a number of beneficial ways. For example, 3 H or 14 Isotopically labeled compounds of formula I, incorporating radioactive isotopes such as C, are suitable for drug and / or substrate tissue distribution assays. 3 H) and carbon-14 ( 14 C) is particularly preferred due to its simple preparation and excellent detectability. Heavier isotopes (e.g., deuterium ( 2Incorporation of H) into compounds of Formula I has therapeutic advantages due to the higher metabolic stability of the isotopically labeled compounds. Higher metabolic stability translates directly into increased in vivo half-life or lower dosages, which will represent a preferred embodiment of the present invention under most circumstances. Isotopically labeled compounds of Formula I can generally be prepared by carrying out the procedures disclosed in the synthetic schemes and related descriptions herein, in the Examples section, and in the Preparations section, replacing non-isotopically labeled reactants with readily available isotopically labeled reactants.
[0087] deuterium( 2 H) can also be incorporated into a target compound of Formula I to manipulate the compound's oxidative metabolism through the primary kinetic isotope effect. The primary kinetic isotope effect is the change in the rate of a chemical reaction due to the exchange of an isotope nucleus, which is secondary to the change in ground state energy required for covalent bond formation after this isotope exchange. The exchange of a heavier isotope usually results in a lowering of the ground state energy for the chemical bond, which in turn causes a reduction in the rate of rate-limiting bond breaking. If the bond breaking occurs in or near a saddle point region along the coordinate of a multi-product reaction, the product distribution ratio can be substantially altered. By way of illustration: when deuterium is attached to a carbon atom at a non-exchangeable position, k M / k D A rate difference of 2 to 7 is typical. If this rate difference is successfully applied to an oxidation-prone compound of formula I, the in vivo profile of the compound can be dramatically altered, resulting in improved pharmacokinetic properties.
[0088] When discovering and developing therapeutic agents, those skilled in the art attempt to optimize pharmacokinetic parameters while retaining desirable in vitro properties. It is reasonable to assume that many compounds with poor pharmacokinetic profiles are prone to oxidative metabolism. Currently available in vitro liver microsome assays provide valuable information about the course of this type of oxidative metabolism, which in turn allows for the rational design of deuterated compounds of Formula I with improved stability through resistance to such oxidative metabolism. Significant improvements in the pharmacokinetic profile of compounds of Formula I can thereby be obtained, improving in vivo half-life (t), concentration at maximum therapeutic effect (C), and other properties. max ), area under the dose-response curve (AUC), and F; and quantitatively in terms of reduced clearance, dose, and material cost.
[0089] The following is intended to illustrate what has been described above: A compound of Formula I, which has multiple potential attack sites for oxidative metabolism (e.g., benzylic hydrogen atoms and hydrogen atoms attached to nitrogen atoms), is prepared as a series of analogs in which various combinations of hydrogen atoms are replaced with deuterium atoms (so that some, most, or all of these hydrogen atoms can be replaced with deuterium atoms). Determination of half-life allows for a convenient and accurate determination of the extent to which resistance to oxidative metabolism has been improved. In this way, it is determined that the half-life of the parent compound can be extended by up to 100% as a result of this type of deuterium-hydrogen exchange.
[0090] Deuterium-hydrogen exchange in compounds of Formula I can also be used to achieve favorable modification of the metabolic spectrum of the starting compound to reduce or eliminate unwanted toxic metabolites. For example, if a toxic metabolite arises through oxidative carbon-hydrogen (C-H) bond cleavage, it can be reasonably expected that a deuterated analog will significantly reduce or eliminate the production of the unwanted metabolite, even if the specific oxidation is not the rate-limiting step. Further state-of-the-art information on deuterium-hydrogen exchange may be found, for example, in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990; Reider et al., J. Org. Chem. 52, 3326-3334, 1987; Foster, Adv. Drug Res. 14, 1-40, 1985; Gillette et al., Biochemistry 33(10) 2927-2937, 1994; and Jarman et al. Carcinogenesis 16(4), 683-688, 1993.
[0091] The present invention also relates to medicaments comprising at least one compound of formula I and / or its pharmaceutically acceptable derivatives, solvates, stereoisomers and mixtures thereof in any ratio, and optionally excipients and / or adjuvants, which of course should be understood as including solvates of the compounds and salts.
[0092] Pharmaceutical preparations can be administered in the form of dosage units containing a predetermined amount of active ingredient per dosage unit. Such units can contain, for example, 0.5 mg to 1 g, preferably 1 mg to 700 mg, particularly preferably 5 mg to 100 mg of a compound according to the present invention, depending on the condition to be treated, the method of administration, and the patient's age, weight, and disease, or pharmaceutical preparations can be administered in the form of dosage units containing a predetermined amount of active ingredient per dosage unit. Preferred dosage unit formulations are those containing the daily dose or partial dose as indicated above, or a corresponding fraction thereof of the active ingredient. Furthermore, pharmaceutical preparations of this type can be prepared using processes commonly known in the pharmaceutical arts.
[0093] Pharmaceutical formulations can be adapted for administration via any suitable method desired, for example, oral (including buccal or sublingual), rectal, nasal, topical (including buccal, sublingual, or transdermal), vaginal, or parenteral (including subcutaneous, intramuscular, intravenous, or intradermal) administration. Such formulations can be prepared using any process known in the pharmaceutical art, for example, by combining the active ingredient with the excipient(s) or adjuvant(s).
[0094] Pharmaceutical formulations adapted for oral administration may be administered as discrete units, such as, for example, capsules or tablets; powders or granules; solutions or suspensions in aqueous or non-aqueous liquids; edible foams or foam foods; or oil-in-water or water-in-oil liquid emulsions.
[0095] Thus, for example, in the case of oral administration in the form of a tablet or capsule, the active ingredient component can be combined with an oral, non-toxic, and pharmaceutically acceptable inert excipient, such as, for example, ethanol, glycerol, water, etc. Powders are prepared by comminuting the compound to a suitable fine size and mixing it with a pharmaceutical excipient, such as, for example, an edible carbohydrate, such as, for example, starch or mannitol, comminuted in a similar manner. Flavors, preservatives, dispersants, and dyes can also be present.
[0096] Capsules are produced by preparing a powder mixture as described above and filling it into formed gelatin shells. For example, glidants and lubricants, such as silicic acid, talc, magnesium stearate, calcium stearate, or polyethylene glycol, which are highly dispersible in solid form, can be added to the powder mixture before filling. Disintegrants or solubilizers, such as agar-agar, calcium carbonate, or sodium carbonate, can also be added to improve the availability of the medicament after the capsule is taken.
[0097] Additionally, if desired or necessary, suitable binders, lubricants, disintegrants, and dyes may also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars (such as glucose or beta-lactose), corn sweeteners, natural and synthetic gums (such as acacia, tragacanth, or sodium alginate), carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrants include, but are not limited to, starch, methylcellulose, agar, bentonite, xanthan gum, and the like. Tablets are formulated, for example, by preparing a powder mixture, granulating or dry-pressing the mixture, adding a lubricant and disintegrant, and compressing the entire mixture to give tablets. Powder mixtures are prepared as described above by mixing the powdered compound with a diluent or base, and optionally with binders (such as, for example, carboxymethylcellulose, alginate, gelatin, or polyvinylpyrrolidone), solution retarders (such as, for example, paraffin), absorption enhancers (such as, for example, quaternary salts), and / or absorbents (such as, for example, bentonite, kaolin, or dicalcium phosphate). The powder mixture can be granulated by wetting it with a binder (such as, for example, syrup, starch paste, acacia mucilage, or solutions of cellulose or polymer materials) and pressing it through a sieve. As an alternative to granulating, the powder mixture can be passed through a tablet press, giving irregularly shaped lumps which can be broken up to form granules. The granules can be lubricated to prevent sticking to the tablet dies by adding stearic acid, a stearate salt, talc, or mineral oil. The lubricated mixture is then compressed to give tablets. The compounds according to the invention can also be combined with a free-flowing inert excipient and then compressed directly to give tablets, without carrying out either the granulation or dry-pressing steps.A clear or opaque protective layer consisting of a shellac sealing layer, a layer of sugar or polymer material, and a gloss layer of wax may be present. Dyes can be added to these coatings in order to be able to distinguish between different dosage units.
[0098] Oral liquids, such as solution, syrup and elixir, can be prepared in dosage unit form, so that a predetermined amount contains a predetermined amount of compound.Syrup can be prepared by dissolving compound in aqueous solution with suitable flavor, while elixir is prepared using non-toxic alcoholic vehicle.Suspension can be prepared by dispersing compound in non-toxic vehicle.Solubilizer and emulsifier (such as ethoxylated isostearyl alcohol and polyoxyethylene sorbitol ether), preservative, flavor additive (such as peppermint oil, or natural sweetener or saccharin, or other artificial sweetener, etc.) can also be added.
[0099] Dosage unit formulations for oral administration can, if desired, be encapsulated in microcapsules. Formulations can also be prepared so as to provide extended or delayed release, for example, by coating or embedding particulate materials in polymers, waxes, etc.
[0100] The compounds of Formula I, and their pharmaceutical salts, tautomers, and stereoisomers, can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from various phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.
[0101] The compounds of Formula I, as well as their salts, tautomers, and stereoisomers, can also be delivered using monoclonal antibodies as individual carriers to which the compound molecules are coupled. The compounds can also be coupled to soluble polymers as targeted drug carriers. Such polymers include polyvinylpyrrolidone, pyran copolymers, polyhydroxypropylmethacrylamidephenol, polyhydroxyethylaspartamidophenol, or polyethylene oxide polylysine substituted with palmitoyl radicals. The compounds can also be coupled to a class of biodegradable polymers suitable for achieving controlled drug release, such as polylactic acid, poly-epsilon-caprolactone, polyhydroxybutyric acid, polyorthoesters, polyacetals, polydihydroxypyrans, polycyanoacrylates, and crosslinked or amphiphilic hydrogel block copolymers.
[0102] Pharmaceutical formulations adapted for transdermal administration can be administered as independent patches for prolonged contact with the epidermis of the recipient. Thus, for example, the active ingredient can be delivered from the patch by iontophoresis, as described in general terms in Pharmaceutical Research, 3(6), 318 (1986).
[0103] Pharmaceutical compounds adapted for topical administration can be formulated as ointments, creams, suspensions, lotions, powders, solutions, pastes, gels, sprays, aerosols, or oils.
[0104] For the treatment of the eye or other external tissues, for example, the mouth and skin, the formulations are preferably applied as topical ointments or creams.In the case of formulations to give an ointment, the active ingredient can be employed with either a paraffinic or water-miscible cream base.Alternatively, the active ingredient can be formulated to give a cream with an oil-in-water cream base or a water-in-oil base.
[0105] Pharmaceutical formulations adapted for topical application to the eye include eye drops, in which the active ingredient is dissolved or suspended in a suitable carrier, especially an aqueous solvent. Pharmaceutical formulations adapted for topical application in the mouth encompass lozenges, troches, and mouthwashes.
[0106] Pharmaceutical formulations adapted for rectal administration can be administered in the form of suppositories or enemas. Pharmaceutical formulations adapted for nasal administration, in which the carrier substance is a solid, include coarse powders, for example, having a particle size in the range of 20 to 500 microns, and are administered in the manner in which snuff is taken, i.e., by rapid inhalation through the nasal passages from a powder-containing container held close to the nose. Formulations suitable for administration as nasal sprays or nasal drops, with a liquid as the carrier substance, include solutions of the active ingredient in water or oil. Pharmaceutical formulations adapted for administration by inhalation include finely particulate dusts or mists, which can be generated by various types of pressurized dispensers with aerosols, nebulizers, or inhalers. Pharmaceutical formulations adapted for vaginal administration can be administered as suppositories, tampons, creams, gels, pastes, foams, or spray formulations.
[0107] Pharmaceutical preparations adapted for parenteral administration include aqueous and non-aqueous sterile injection solutions containing antioxidants, buffers, bacteriostats, and solutes that render the preparation isotonic with the blood of the recipient to be treated; and aqueous and non-aqueous sterile suspensions, which may contain a suspending medium and a thickening agent. The preparations may be provided in single-dose or multi-dose containers (e.g., sealed ampoules and vials) and may be stored in a freeze-dried (lyophilized) state, requiring only the addition of a sterile carrier liquid (e.g., water for injection) immediately prior to use. Injection solutions and suspensions prepared according to a recipe may be prepared from sterile powders, granules, and tablets.
[0108] It will be appreciated that in addition to the constituents specifically mentioned above, the formulations may also include other agents customary in the art with respect to the particular type of formulation; thus, for example, formulations suitable for oral administration may include flavors.
[0109] The therapeutically effective amount of a compound of Formula I depends on numerous factors, including, for example, the age and weight of the animal, the precise disease requiring treatment and its severity, the nature of the formulation, and the method of administration, and is ultimately determined by the treating physician or veterinarian. However, an effective amount of a compound according to the present invention will generally be in the range of 0.1 to 100 mg / kg of recipient (mammal) body weight per day, and more typically in the range of 1 to 10 mg / kg of recipient (mammal) body weight per day. Thus, for an adult mammal weighing 70 kg, the practical daily amount will often be between 70 mg and 700 mg, which may be administered as a single dose or, in most cases, in a series of partial doses (e.g., 2, 3, 4, 5, or 6 doses) per day so that the total daily dose is the same. An effective amount of a salt or solvate thereof, or an effective amount of a physiologically functional derivative thereof, may be determined as a fraction of the effective amount of the compound according to the present invention itself. It can be assumed that similar doses would be suitable for the treatment of the other diseases mentioned above.
[0110] This type of combination treatment may be achieved by utilizing simultaneous, sequential, or separate administration of the individual components of the treatment. This type of combination product employs a compound according to the present invention.
[0111] The present invention also relates to a medicament comprising at least one compound of formula I, and / or its pharmaceutically acceptable salts, tautomers, and stereoisomers, and mixtures thereof in any ratio, and at least one additional pharmaceutically active ingredient (synonymous with active pharmaceutical ingredient).

[0114] "Treating," as used herein, means the total or partial alleviation of symptoms associated with a disorder or disease, or the slowing or halting of further progression or worsening of those symptoms, or the prevention or prophylaxis of a disease or disorder in a subject at risk of developing the disease or disorder.
[0115] The term "effective amount" in reference to a compound of Formula I may mean an amount that is capable of alleviating, in whole or in part, the symptoms associated with a disorder or disease, or slowing or halting the further progression or worsening of those symptoms, or preventing or providing prophylaxis for a disease or disorder in a subject having or at risk of developing a disease disclosed herein (such as an inflammatory disease, immunological disease, cancer, or metabolic disease).
[0116] The phrase "effective amount" refers to an amount of a drug or an amount of a pharmaceutical active ingredient that elicits the biological or medical response sought or desired, for example, by a researcher or physician, in a tissue, system, animal, or human. Additionally, the phrase "therapeutically effective amount" refers to an amount that has the following consequences: improved treatment, cure, prevention, or elimination of a disease, syndrome, illness, complaint, disorder, or side effect, or even a reduction in the prevalence of a disease, complaint, or disorder, compared to a corresponding subject not receiving this amount.
[0117] The expression "therapeutically effective amount" also encompasses the amounts which are effective for increasing normal physiological function.
[0118] In one embodiment, an effective amount of a compound of Formula I is an amount that inhibits c-KIT kinase in cells, e.g., in vitro or in vivo. In some embodiments, an effective amount of a compound of Formula I inhibits c-KIT in cells by 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 99% compared to the activity of c-KIT kinase in untreated cells. An effective amount of a compound of Formula I may be, for example, in a pharmaceutical composition, at a level that will produce the desired effect; for example, about 0.005 mg / kg (of the subject's body weight) to about 10 mg / kg (of the subject's body weight) in a unit dosage for both oral and parenteral administration.

[0141] Assays and Measurements c-Kit(V654A) assay: c-Kit(V654A) (recombinant human c-Kit tagged with GST at the N-terminus, containing the V654A mutation at amino acid 544-terminal) is incubated with 8 mM MOPS (pH 7.0), 0.2 mM EDTA, 250 μM GGMEDIYEFMGGKKK, 10 mM Mg acetate, and [gamma-33P-ATP] (specific activity approximately 500 cpm / pmol, concentration 200 μM). The reaction is initiated by the addition of the MgATP mix. After a 40-minute incubation at room temperature, the reaction is stopped by the addition of a 3% phosphoric acid solution. 10 μL of the reaction is then spotted onto a P30 filtermat and washed three times for 5 minutes in 75 mM phosphoric acid and once in methanol prior to drying and scintillation counting.
[0142] Assay principle for cellular testing of cKIT mutant inhibitors The GIST430 cell line, which expresses a constitutively active cKIT receptor tyrosine kinase (Δ560-576 deletion), and the imatinib-resistant GIST430 / 654 cell line, which expresses a constitutively active mutant cKIT receptor tyrosine kinase (Δ560-576 deletion and V654A point mutation), were employed to assess the cellular efficacy of compounds. The cellular activity of mutant cKIT was determined by the degree of cKIT autophosphorylation at tyrosine 307 using a Luminex-based bead assay. GIST430 cells were seeded at 22,000 cells per well of a 96-well plate in 100 μl of medium (85% IMDM / 15% FCS), and GIST430 / 654 cells were seeded at 25,000 cells per well of a 96-well plate in 100 μl of medium (85% IMDM / 15% FCS supplemented with 100 nM imatinib). The following day, compounds were added in serial dilutions for 45 min. The cells were then lysed in 90 μl lysis buffer (20 mM Hepes (pH 7.5), 200 mM NaCl, 1.5 mM MgCl2 × 6H2O, 0.4 mM EDTA, 1% Triton-X-100, 1% Phosphatase Inhibitor II, 20 mM β-glycerol phosphatase, 0.1% Protease Inhibitor Cocktail III, 0.01% Benzonase), and the lysates were clarified by centrifugation through a 96-well filter plate (0.65 μm). The samples were incubated overnight at 4°C with Luminex beads coupled with anti-total cKIT antibody under gentle agitation. For detection of phospho-Y307-cKIT, a phospho-specific antibody and a species-specific PE-labeled secondary antibody were added. The amount of phospho-Y307-cKIT was measured in a Luminex 200 instrument measuring 100 events per well within 60 seconds.
[0143] Counts from compound-treated samples were calculated as a percentage of the control from vehicle (0.3% DMSO)-treated samples. Dose-response curves were fitted and IC 50Values were determined using Genedata Screener software.
[0144] Determination of efflux ratio (ER) in Caco-2 cells The efflux rate of the test compound was calculated as the apparent permeability (P app The chromatin concentration was determined in the Caco-2 human epithelial colorectal adenocarcinoma cell line (TC7 clone) using the chromatin concentration (ΔΨ) calculation. Cell monolayers were differentiated in vitro for 14 days prior to the experiment. Test compounds (at a final concentration of 1 μM in HBSS, pH 7.4) were then applied to the donor side, while HBSS buffer (pH 7.4) was added to the receiver wells. The final DMSO concentration during the incubation did not exceed 1%. The plates were then incubated in a 5% CO2 incubator (37°C, 100% humidity). At the end of the 2-hour incubation period, 50 μL samples were removed from both the donor and receiver wells and diluted 1:1 with an equal volume of acetonitrile for LC-MS / MS analysis. LC-MS / MS analysis used a one-point calibration method from a 1 μM standard solution diluted 1:1 with an equal volume of acetonitrile (matching the test sample).
[0145] The data was used to calculate the apparent permeability of the compound from apical to basolateral (P app,AB ) direction and basolateral to apical (P app,BA ) direction and at a concentration of 1 μM. app Values were calculated from the concentrations in the donor and receiver compartments using the following formula:

[0146] Determination of solubilization degree In a 96-well filtration plate, 2 μL of a 10 mM solution of test compound in DMSO is added to 98 μL of 20 mM Sorensen's phosphate buffer (pH 7.4). The mixture is incubated at room temperature for 120 min with stirring at 250 rpm, followed by centrifugation at 2500 rpm for 3 min. After dilution by a factor of 2, the concentration of the test compound is determined by comparing with the corresponding standard compound using HPLC / UPLC with detection at a suitable wavelength.
[0147] example In certain exemplary embodiments, compounds are prepared according to the following general procedures, as depicted and described in the examples below. While the general methods illustrate the synthesis of certain compounds of the present invention, it will be understood that the following general methods, as well as other methods known to those of skill in the art, can be applied to all compounds as described herein, as well as each subclass and species of these compounds.
[0148] The following data, determined by the assays described above and set forth in Tables 2 and 3 below, illustrate the efficacy of embodiments of the present invention in terms of inhibition of cKit(V654A) GIST430 / 654, respectively. As can be seen from the tables, the compounds exhibited excellent IC 50 These compounds have potent potent potency, many of which are in the low nanomolar concentration range. In addition, the compounds are selective, particularly compared to the closely related kinase FLT3 ("fms-like tyrosine kinase 3"). Embodiments tested against a broader panel of kinases (including JAKs) have been found to show significantly better selectivity than those kinases.
[0149] In addition to excellent inhibitory potency, certain preferred embodiments of the present invention have been found to possess a balance of promising pharmacokinetic properties (including bioavailability) as experimentally determined by solubilization and efflux, with acceptable to excellent levels of unwanted blockage of the hERG potassium channel. The results of the experimental efflux measurements are provided in Table 4 below.
