TECHNICAL FIELD

The present invention relates to novel 5-substituted difluoropiperidine derivatives, salts, hydrates thereof and polymorphs thereof, and in particular to 5-substituted difluoropiperidine compounds having a capacity to penetrate the blood-brain barrier.

BACKGROUND

Biological signaling refers to the stimulation or inhibition of signaling sent to the cell, through a series of signal transmission, resulting in intracellular biological response. Many studies have been conducted on many signaling pathways and their biological responses. Different defects in the signaling pathways have been found to be responsible for many diseases, including various forms of cancer, metabolic disorders, inflammatory diseases, vascular and neuronal diseases. These defects often occur at the level of genes, such as DNA overexpression, insertion, deletion or translocation, or protein overexpression, and result in uncontrolled cancer cells growth.

Signal transduction is often mediated by certain proteins known as kinases. Kinases are usually divided into protein kinases and lipid kinases, and some kinases that exhibit double specificity. Protein kinases are phosphorylated enzymes that catalyze the phosphorylation of other proteins and/or autophosphorylated and can be classified based on their effect on the substrate, for example: tyrosine kinases refer to phosphorylated tyrosine residues (e.g., Kit, EGFR, HFR2, VEGFR, PDGFR, SRC and ABL, etc.), serine/threonine kinases refer to phosphorylated serine and/or threonine residues (e.g., mTORC1, mTORC2, ATM, ATR, Akt, etc.), and the dual specific kinase phosphorylates the tyrosine, serine and/or threonine residues of the substrate.

Vascular endothelial cell growth factor receptor (VEGFR) is a transmembrane protein tyrosine kinase, including vascular endothelial cell growth factor receptor factor receptor VEGFR1 (FLT-1), VEGFR2 (FLK-1/KDR) and VEGFR3 (FLT-4). Upon binding to vascular endothelial cell growth factor (VEGF) ligand, the induced VEGFR2 receptor forms a homopolymer or heterodimer with another VEGFR2 receptor or another family member, for example, VEGFR1 or VEGFR3, resulting in VEGFR2 tyrosine kinase activity activated. The activated VEGFR2 then phosphorylates its substrate, leading to multiple downstream pathways in the cell, including the Pl3K pathway (promoting the proliferation of endothelial cells), activating Src signaling, and ultimately affecting endothelial cell migration, and RAS-RAF-MEK-ERK pathway (involving cell proliferation). VEGFR receptor signal transduction and its involvement in tumors, see, for example, Adamis et al. Nature Review Drug Discovery. 2016; 15:385-403; Romos et al. Anticancer Agents Med Chem. 2007 7(2), 223-245 and Brujin et al. Pharmacological Reviews December 2004, 56 (4) 549-580. The proto-oncogene SRC belongs to non-receptor protein tyrosine kinases, including c-Src, Yes, Fyn, Fgr, Yrk, Lyn, Blk, Hck, and Lck that can be activated by many transmembrane proteins, including: adhesion receptors, receptor tyrosine kinases, G protein-coupled receptors and cytokine receptors, which lead to cell survival, angiogenesis, proliferation and invasion way. In particular, FYN is involved in a variety of central nervous system (CNS) and peripheral immune system transduction pathways, playing a regulatory role and the function of T cell development and activation, as a potential target for the treatment of Alzheimer's disease. See, for example, Wang et al, Neuroscience. 262 (3): 118-128; Botta et al. Current Medicinal Chemistry, 2011, 18, 2921-2942; Strittmatter et al. Alzheimer's Research & Therapy 2014, 6: 8.

Glioma is the most common primary brain tumor, accounting for 40-50% of brain tumors. The high expression of vascular endothelial cell growth factor receptor 2 (VEGFR2) in glioma increases its kinase activity, leading to vascular proliferation and rapid growth of cancer cells in the brain. VEGFR family signal transduction has been described in many human cancers, including lung, gastrointestinal, kidney cancer, etc., to promote new angiogenesis and tumor cell survival. Therefore, the VEGFR family represents a reasonable target for the development of anticancer drugs. Due to the presence of the blood-brain barrier (BBB), no drugs targeting VEGFR2 are effective for glioma. Radiotherapy, chemotherapy and surgery are still the main treatment methods, but the therapeutic effect is limited. See, for example, Oberoi et al. Neuro-Oncology 18(1), 27-36, 2016.

SUMMARY

In view of the fact that the above-mentioned central nervous system cancers have VEGFR2 overexpression to promote new angiogenesis, the VEGFR2 inhibitor that can cross the blood-brain barrier reaches an effective amount in the brain and is particularly useful in the treatment or prevention of cancer. The high expression of FYN in Alzheimer's disease is a potential target for the treatment of Alzheimer's disease. The FYN inhibitor that can cross the blood-brain barrier reaches an effective amount in the brain and is particularly useful in the treatment or prevention of Alzheimer's disease.

ee value (90−10)/100=80%.

Thus, a composition containing 90% of one enantiomer and 10% of the other enantiomer is said to have an enantiomeric excess of 80%. Some of the compositions described herein contain at least about 50% enantiomeric excess, about 75%, about 90%, about 95%, or about 99% of the S enantiomer. In other words, the composition comprises an enantiomeric excess of the S enantiomer in the R enantiomer. In other embodiments, some of the compositions described herein contain at least about 50% enantiomeric excess, about 75%, about 90%, about 95%, or about 99% of the R enantiomer. In other words, the composition comprises an enantiomeric excess of the R enantiomer in the S enantiomer. For example, an isomer/enantiomer may, in some embodiments, provide the ee value of the corresponding enantiomer, and may also be referred to as “optical enrichment”, “enantiomerically enriched”, “enantiomerically pure” and “non-racemic”, which are used interchangeably herein. These terms mean that the weight percentage of one of the enantiomers is greater than the amount of the control mixture of the composition than the racemic composition in one enantiomer (e.g., greater than 1:1 by weight). For example, the enantiomerically enantiomerically enantiomer of the S enantiomer is present at about 75% by weight of the enantiomer of the enantiomer, e.g., greater than about 50% by weight of the compound, At least about 80% by weight. In some embodiments, the enrichment is greater than about 80% by weight, providing a “substantially enantiomerically enriched”, “substantially enantiomerically pure” or “substantially non racial” Means that the weight of the enantiomer has at least 85% of the composition, such as at least about 90% by weight of the formulation, and further, for example, at least about 95% by weight, relative to one of the other enantiomers. In certain embodiments, the compounds provided herein may be present in an amount of from about 90% by weight of at least one enantiomer. In other embodiments, the compound may be present in an amount of at least about 95%, about 98%, or about 100% by weight of an enantiomer. In some embodiments, the compounds are (S)- and (R)-racemic mixtures. In other embodiments, there is provided a process wherein the individual compound (S) of the mixture is predominantly a mixture of compounds or (R)- is a mixture of predominantly present compounds. For example, the compound mixture has greater than about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, about 99.5%, or more.

In other embodiments, the compound mixture comprises, in addition to their stereochemical orientation, i.e., (S)- or (R)- the same chemical entity. For example, if there is a —CH(R)— unit in the compound, and R is not hydrogen, then —CH(R)— is the same chemical entity as the (S)- or (R)-stereochemistry orientation. In some embodiments, the (S)-isomer in the mixture of the same chemical entities is present in an (S)-enantiomeric excess of greater than about 55% to about 99.5%, greater than about 60% to about 99.5%, greater than about 65% to about 99.5%, greater than about 90% to about 99.5%, greater than about 90% to about 99.5%, greater than about 90% to about 99.5% % To about 99.5%, greater than about 95% to about 99.5%, greater than about 96% to about 99.5%, greater than about 97% to about 99.5%, greater than about 98% to greater than about 99.5%, greater than about 99% to about 99.5% or more.

Enantiomers can be isolated from racemic mixtures by any method known to those skilled in the art, including chiral high performance liquid chromatography (HPLC), chiral salt formation and crystallization, or non-synthetic synthesis. See, for example, Enantiomers, Racemates and Resolutions (Jacques, Ed., Wiley Interscience, New York, 1981); Wilen et al., Tetrahedron 33: 2725 (1977); Stereochemistry of Carbon Compounds (EL Eliel, Ed., McGraw-Hill, N Y, 1962); and Tables of Resolving Agents and Optical Resolutions p. 268 (EL EIM, Et al., Univ. Of Notre Dame Press, Notre Dame, Ind. 1972).

The optical isomers can also be obtained by cleaving the racemic mixture in a conventional manner with an optically active acid or base, for example, by forming a diastereomeric salt. Examples of suitable acids include, but are not limited to, tartaric acid, diacetyl, dibenzoyl, dimethoyltartaric acid and camphorsulfonic acid. Separation of isomers from the mixture of optically active bases of these salts can be achieved by diastereomeric crystallization. Alternatively, the reaction of the open compound with the optically pure acid or optically pure isocyanate of the activated form involves the synthesis of covalent diastereomeric molecules. The synthetic enantiomers can be isolated by conventional methods such as chromatography, distillation, crystallization or sublimation, followed by hydrolysis to provide enantiomerically enriched compounds. The optically active compound can also be obtained by using an active material. In some embodiments, these isomers may be in the form of free acids, free bases, esters or salts. In certain embodiments, the pharmaceutically acceptable form is a tautomer. As used herein, the term “tautomer” is a type of isomer that includes at least one form of migration and alteration of two or more interconverted compounds derived from hydrogen atoms and covalent bonds (e.g. a single bond to a double bond, a triple bond to a single bond, or vice versa). “Tautomerism” includes proton or proton migration tautomerism, which is considered a subset of acid-base chemistry. “Proton transfer tautomerism” involves proton migration accompanied by a bond change. The exact proportion of tautomers depends on several factors, including temperature, solvent and pH. Among them, tautomerism is possible (for example, in solution), and the chemical equilibrium of the tautomer can be reached. Tautomerism (i.e., the reaction to provide a tautomer pair) can be catalyzed by an acid or base, or presence or absence of an external agent can occur. Such as tautomeric additions include, but are not limited to, ketones to enol; amides to imides; enamines to imines; and one form of enamines to different enamines. Specific examples of ketone to enol tautomer are pentane-2,4-dione and 4-hydroxypent-3-en-2-one tautomers. Another example of tautomerism is phenol and ketone tautomerism. Specific examples of phenol and ketone tautomers are pyridine 4-phenols and pyridine-4-(1H)-one tautomers.

Unless otherwise indicated, it is meant that the structures described herein include compounds that exist only in one or more isotopically enriched atoms. For example, the compound has a structure in which one hydrogen is replaced by deuterium or tritium, or the carbon 13 or carbon 14 within the disclosed range is enriched.

The present disclosure also includes those “isotopically labeled derivatives” which are pharmaceutically acceptable forms of those compounds recited herein, except that one or more atoms are of a different atomic mass generally found in nature. Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ¹⁸F, and ³⁶Cl. Certain isotopically labeled disclosed compounds (e.g., those labeled ³H and ¹⁴C) are useful for the determination of compounds and/or substrate tissue distribution. Tritium (i.e., ³H) and carbon 14 (i.e., ¹⁴C)isotopes can be readily prepared and tested. In addition, substitutions with heavier isotopes such as deuterium (i.e., ²H or D) may provide certain therapeutic advantages resulting from greater metabolic stability (e.g., increasing the half-life or reduced dose requirements in vivo). Isotope-labeled disclosed compounds can generally be prepared by replacing an isotopically labeled reagent with a non-isotope-labeled reagent. In some embodiments, provided herein may also contain one or more non-natural atomic isotopes to form such compounds. All isotopic variants of the disclosed compounds are used herein, whether radioactive or not, within the scope of this disclosure. In some embodiments, the radiolabeled compound may be used to study the metabolic and tissue distribution of the compound to alter the metabolic pathway, or rate or other biological function.

In certain preferred embodiments, a pharmaceutical composition comprising an oral administration of a compound as disclosed herein, and a pharmaceutical excipient suitable for oral administration. In some embodiments, there is provided herein a pharmaceutical composition for oral administration: (1) optionally an effective amount of a disclosed compound; (2) an effective amount of one or more second agents; and (3) One or more pharmaceutically acceptable excipients for oral administration. In some embodiments, the pharmaceutical composition further comprises: (4) an effective amount of a third reagent.

In some embodiments, the pharmaceutical composition may be a liquid pharmaceutical composition suitable for oral administration. Pharmaceutical compositions suitable for oral administration may be used as discrete dosage forms, such as capsules, cachets, or tablets, or liquids, solutions, aerosol sprays or suspensions of a predetermined amount of active ingredient containing powder or granules, water or non-aqueous liquid, the liquid emulsion in water or water in the liquid emulsion. Such dosage forms may be prepared by any pharmaceutical method, but all methods include the step of preparing the composition by uniformly and intimately associating the active ingredient with a liquid carrier, a liposome or a finely divided solid carrier, or both. In general, the pharmaceutical composition is formed by mixing the active ingredient homogeneously and intimately with a liquid carrier or a finely divided solid carrier or both, and if necessary, shaping the product into the desired form. For example, the tablet may be one or more components that may be pressed or molded. The tablet may be formed by mixing the free-flowing form such as the active ingredient of the powder or granule, optionally with an excipient such as, but not limited to, a binder, a lubricant, an inert diluent and/or a surfactant or dispersant mix, press in the right machine. The molded tablets may be prepared by molding a mixture of powdered compounds moistened with an inert liquid diluent in a suitable machine. The tablets may optionally be uncoated, coated or nicked and may be formulated to provide a slow or controlled release of the active ingredient therein, thereby providing a sustained effect over a longer period of time, such as, for example, glyceryl monostearate or glyceryl distearate. Formulations for oral use may also be hard gelatin capsules in which the active ingredient may be mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as a soft gelatin capsule in which the active ingredient may be mixed with water or an oil medium, for example, peanut oil, liquid paraffin or olive oil is mixed.

The active ingredient can be tightly combined with a pharmaceutically acceptable carrier by conventional drug mixing techniques. The carrier may take a variety of forms depending on the form of the desired formulation administration. In the preparation of pharmaceutical compositions for oral dosage forms, any of the usual pharmaceutical media can be used as carriers, for example, water, glycols, oils, ethanol, flavoring agents, preservatives, colorants, and oral liquid preparations (e.g., liquids, solutions, and elixirs) or aerosols, or carriers such as starch, sugar, microcrystalline cellulose, diluents, granules, lubricants, binders, and disintegrants can be used in oral solid preparations. The lactose is not used in some embodiments. In some embodiments, the compound may be mixed with lactose, sucrose, starch powder, cellulose ester of alkanoic acid, cellulose alkyl ester, talc, stearic acid, magnesium stearate, magnesium oxide, calcium phosphate, sodium phosphate, calcium sulfate, sodium sulfate, gelatin, gum arabic, sodium alginate, polyvinylpyrrolidone and/or polyvinyl alcohol for further formulation. For example, the preparation of solid oral preparations, suitable carriers also include powders, capsules and tablets. In some embodiments, the tablet may be coated by standard aqueous or non-aqueous techniques.

Suitable for use in pharmaceutical compositions and dosage forms, including, but not limited to, corn starch, potato starch, or other starches, gelatin, natural binders and synthetic gums such as gum arabic, sodium alginate, alginic acid, other alginic acid salts, powdered tragacanth, guar gum, cellulose and derivatives thereof (e.g., ethylcellulose, cellulose acetate, carboxymethylcellulose calcium, sodium carboxymethyl cellulose), polyvinylpyrrolidone, cellulose, pregelatinized starch, hydroxypropylmethyl cellulose, microcrystalline cellulose, and mixtures thereof.

Examples of suitable fillers for use in pharmaceutical compositions and dosage forms include, but are not limited to, talc, calcium carbonate (e.g., granules or powders), microcrystalline cellulose, powdered cellulose, glucose binders, kaolin, mannitol, silicic acid, sorbitol, starch, pregelatinized starch, and mixtures thereof.

The disintegrant may be used in a pharmaceutical composition as provided herein to provide a tablet that disintegrates when exposed to a water environment. Too much disintegrant can cause the tablet to disintegrate in the bottle. Too little may not be sufficient to disintegrate, and thus can change the release rate and extent of the active ingredient of the dosage form. Thus, the disintegrant should be sufficient, neither too little nor too much to detrimentally release the active ingredient. The amount of disintegrant will depend on the formulation and mode of administration, and may be readily implemented by one of ordinary skill in the art. About 0.5 to about 15% by weight of a disintegrant, or about 1 to about 5% by weight of a disintegrant, may be used in a pharmaceutical composition. To form disintegrants and dosage forms for pharmaceutical compositions including, but not limited to, agar, alginic acid, calcium carbonate, microcrystalline cellulose, croscarmellose, crospovidone, sodium acetate, potato or tapioca starch, other starches, preformed starch, clay, other algae, other cellulose, gums or mixtures thereof.

Lubricants may be used to form pharmaceutical compositions including, but not limited to, calcium stearate, magnesium stearate, mineral oil, light mineral oil, glycerol, sorbitol, mannitol, polyethylene glycol, other diols, stearic acid, sodium lauryl sulfate, talc, hydrogenated vegetable oils (e.g., peanut oil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil and soybean oil), zinc stearate, ethyl oleate, Ethyl laurate, agar or mixtures thereof. Lubricants also include, for example, silica gel, coagulated aerosols, or mixtures thereof. The lubricant may optionally be added in an amount of less than about 1% by weight of the pharmaceutical composition.

When aqueous suspensions and/or elixirs are used for oral administration, the active ingredient may be combined with various sweetening or flavoring agents, coloring agents or dyes, for example, emulsifiers and/or suspending agents, diluents, for example, water, ethanol, propylene glycol, glycerol, and combinations thereof.

Surfactants that may be used to form pharmaceutical compositions and dosage forms include, but are not limited to, hydrophilic surfactants, lipophilic surfactants, and mixtures thereof. Suitable hydrophilic surfactants may generally have an HLB value of at least about 10, and suitable lipophilic surfactants may generally have an HLB value of less than about 10. The empirical parameter used to characterize the relative hydrophilicity and hydrophobicity is the hydrophilic lipophilic balance value HLB (“HLB” value). The lower HLB value of the surfactant is more lipophilic or hydrophobic and has a greater solubility in the oil while the active agent with a higher HLB value is more hydrophilic and has a greater aqueous solution of the solubility. Hydrophilic surfactants are generally considered to be those having HLB values greater than about 10, however, anions, cations or zwitterionic compounds, HLB scales are generally not applicable. Similarly, lipophilic (i.e., hydrophobic) surfactants are those having an HLB value equal to or less than about 10. However, the HLB value of the surfactant is only a rough guide for general use in industrial, pharmaceutical and cosmetic emulsions.

The hydrophilic surfactant may be ionic or nonionic. Suitable ionic surfactants include, but are not limited to, alkylammonium salts; fusidic acid salts; fatty acid derivatives of amino acids, oligopeptides and polypeptides; derivatives of amino acids, oligopeptides and glycerol esters of polypeptides; lecithin and Phospholipid and its derivatives; carnitine fatty acid ester salts; alkyl sulphates; fatty acid salts; docetyl sodium; acyl lactic acid salts; mono- and diacetylated mono- and diglycerides of tartaric acid esters; succinylated mono- and diglycerides; citrate esters of mono- and di-glycerides; and mixtures thereof.

Drugs that may be usefully combined with these compounds include other kinase inhibitors and/or other chemotherapeutic agents for the treatment of diseases and disorders discussed above. Such agents are described in detail in the art. Preferably, the second therapeutic agent is an agent that can be used for the treatment or prophylaxis of a disease or condition selected from cancer.

In another embodiment, the present invention provides an independent dosage form of a compound of the invention and a second therapeutic agent associated with each other. As used herein, the term “associated with each other” means that the individual dosage forms are packaged together or otherwise connected to each other so that the individual dosage forms are expected to be sold or administered together (less than 24 hours Inside, continuously or simultaneously).

In the pharmaceutical compositions of the present invention, the compounds of the present invention are present in an effective amount. As used herein, the term “effective amount” refers to the severity, duration, or development of a disorder that is sufficient to reduce or ameliorate the disorder to be treated when administered with a suitable dosing regimen, to prevent progression of the disorder, the disruption of the treatment disorder, or the enhancement or improvement of the prophylactic or therapeutic effect of another therapy.

In Freireich et al., (1966) Cancer Chemother Rep 50: 219, the dose-to-animal and human relationships (based on milligrams per square meter of body surface area) are described. The body surface area can be roughly determined according to the height and weight of the patient. See, for example, Scientific Tables, Geigy Pharmaceuticals, Ardley, N.Y., 1970, 537. The effective amount of the compound of the present invention may range from about 0.001 to 1 mg/kg to about 500 mg/kg, from about 0.01 mg/kg to about 50 mg/kg, from about 0.1 mg/kg to about 2.5 mg/kg. Effective dosages may also vary, as will be appreciated by those skilled in the art, depending on the disease being treated, the severity of the disease, the route of administration, the age, sex and general health of the patient, excipient usage, and other treatments method for common use (e.g., the use of other agents), and the judgment of the treatment physician.

For a pharmaceutical composition comprising a second therapeutic agent, the effective amount of the second therapeutic agent is between about 20% and 100% of the dose normally used in a single treatment regimen using only the agent. Preferably, the effective amount is between about 70% and 100% of the normal single therapeutic dose. The normal single therapeutic doses of these second therapeutic agents are well known in the art. See, for example, Wells et al., Pharmacotherapy Handbook, Appleton and Lange, Stamford, Conn. (2000); PDR Pharmacopoeia, Tarascon Pocket Pharmacopoeia 2000, Tarascon Publishing, Loma Linda, Calif. (2000), all of which are incorporated herein as reference. It is expected that some of the second therapeutic agents mentioned herein will act synergistically with the compounds of the present invention. When present, it will allow the effective dose of the second therapeutic agent and/or the compound of the invention to be less than the dosage required for single therapy. This has the advantage that the secondary side effects of the second therapeutic agent or the compound of the present invention are minimized, improved efficacy, improved ease of administration or use, and/or reduced overall cost of the compound preparation or formulation.

Alternatively, additional reagents may be administered prior to, or in connection with, or after the administration of the compounds of the invention. In such combination therapy, the compounds of the present invention and the second therapeutic agents are administered by conventional methods. The administration of the compositions of the invention comprising the compounds of the invention and the second therapeutic agent to the subject does not exclude the same therapeutic agent, any other second therapeutic agent or any of the compounds of the invention at other times during the course of treatment Independent administration of the subject. Wherein the continuous or separate administration, or delaying administration of the second component, should not lose the advantage of the effect produced from the use of the combination.

The effective amount of the second therapeutic agent is well known to those skilled in the art, see, for example, Wells et al., Pharmacotherapy Handbook, Appleton and Lange, Stamford, Conn. (2000); PDR Pharmacopoeia, Tarascon Pocket Pharmacopoeia 2000, Tarascon Publishing, Loma Linda, Calif. (2000) and other medical textbooks. However, determining the optimal effective amount of the second therapeutic agent is within the capabilities of those skilled in the art.

In one embodiment of the invention, when the second therapeutic agent is administered to the subject, the effective amount of the compound of the invention is lower than the effective amount of the second therapeutic agent when no second therapeutic agent is administered. In another embodiment, the effective amount of the second therapeutic agent is less than the effective amount of the second therapeutic agent when the compound of the invention is not administered. In this way, undesirable side effects associated with any of the high doses of the agent can be minimized. The potential advantages for those skilled in the art will be apparent (including, but not limited to, for example, improving the dosing regimen and/or reducing the cost of the drug).

In another aspect, the invention provides the use of any of the compounds of the general formula herein, either alone or in combination with one or more of the second therapeutic agents described herein, in the manufacture of a medicament as a single composition or as a separate dosage form, a medicament for the treatment or prevention of a disease, disorder or symptom listed herein in a subject. Another aspect of the invention is the use of a compound of the general formula herein for the treatment or prevention of a disease, disorder or symptom described herein in a subject.

In other aspects, the methods herein include further comprising those methods of monitoring the response of the subject to therapeutic administration. Such monitoring may include periodic sampling of subject tissue, body fluids, cerebrospinal fluid, samples, cells, proteins, chemical markers, genetic material, etc. as a marker or indicator of a therapeutic regimen. In other methods, by assessing the adaptability of the relevant marker or indicator to such treatment, the subject is pre-screened or identified as requiring such treatment.

In one embodiment, the present invention provides a method of monitoring the progression of therapy. The method comprises determining a diagnostic marker (marker) in a subject suffering from or susceptible to disorders or symptoms described herein (e.g., any target or cell type described herein regulated by the compounds herein) or diagnosed (e.g., screening, assay), wherein the subject has been administered a compound of the present invention sufficient to treat the therapeutic amount of the disease or its symptoms. The level of the marker determined in the method may be compared to a well-known level in a healthy normal control or other diseased patient to establish a disease condition of the subject. In a preferred embodiment, the second level of the marker in the subject is measured at a time point later than the first level of measurement and the two levels are compared to monitor the efficacy of the progression or therapy of the disease. In certain preferred embodiments, the level of the marker prior to treatment in the subject is measured prior to initiation of treatment according to the present invention; the pre-treatment level of the marker may be the same as the marker in the subject after treatment initiation Level to determine the effectiveness of treatment.

In certain method embodiments, the level of marker or marker activity in the subject is determined at least once. The marker level is compared with another measured value, for example, from the same patient, another patient, or another subject that was previously or subsequently acquired by the subject, to determine whether the therapy according to the present invention has the desired effect, and thus allow the dose level to be adjusted as appropriate. The determination of the level of the marker can be carried out using any suitable sampling/expression assay method known in the art or described herein. Preferably, the tissue or liquid sample is first removed from the subject. Examples of suitable samples include blood, urine, cerebrospinal fluid, tissue, mouth or buccal cells, and hair samples containing roots. Other suitable samples are known to those skilled in the art. The determination of protein levels, ctDNA, cfDNA and/or mRNA levels (e.g., marker levels) in the sample can take advantage of any suitable technique known in the art including, but not limited to, enzyme immunoassays, ELISA, radioactive labeling techniques, western blot/chemiluminescence, real-time PCR, electrochemical signals, and the like.

The present invention also provides a kit for the treatment of diseases, disorders or symptoms of those described herein. Such kits include: 1) a pharmaceutical composition comprising any of the compounds of the general formula herein or salts thereof; or a prodrug thereof, or a salt thereof; or a pharmaceutical composition of a hydrate, solvate or polymorph thereof, in a container; and 2) describes a description of the use of the pharmaceutical composition for the treatment of a method comprising a disease, disorder or symptom described herein. The container may be any container or other sealed or sealable device capable of containing the pharmaceutical composition. Examples include a bottle, a separate or multi-chamber reservoir bottle, wherein each partition or compartment comprises a single dose of the composition; a separated foil package, wherein each partition comprises a single dose of the composition, which dispenses a single dose of said composition. The container may be any conventional shape or form known in the art and is made of a pharmaceutically acceptable material such as paper or cardboard boxes, glass or plastic bottles or cans, resealable bags (e.g., The “refill” of the tablet is used to be placed in a different container), or a single dose of blister pack is used to extrude the package from the treatment schedule. The containers used may depend on the exact dosage form involved, for example, conventional cardboard boxes will generally not be used to contain liquid suspensions. It is possible that more than one container can be used together in a single package to market a single dosage form. For example, the tablet may be contained in a bottle, which is then accommodated in the box. Preferably, the container is a blister pack.

The kit may additionally include information and/or instructions from a physician, pharmacist or subject. These memory aids include numbers printed on each compartment or partition containing the agent, which corresponds to the number of days the program or capsule should be ingested, or printed on each compartment or partition week number of days, or cards containing the same type of information.

Example 6 Kinase Inhibition Data

2.5 times of the kinase (VEGFR2 or EGFR or FYN) buffer solution was added to the compound diluted in equal concentration in the 384-well plate and incubated at 22-27° C. for 10 minutes, then 2.5 times of the FAM-labeled peptide substrate and ATP buffer solution were added therein and incubated at 28° C., and then the stop buffer solution was added to stop the reaction. The data was read by Caliper and the following formula was used to calculate the IC50 inhibition: Percent inhibition=(max-conversion)/(max-min)*100. Staurosporine was used as a control. In kinase inhibition assays, some of the compounds of the present invention are effective in inhibiting VEGFR2/FYN/EGFR, so they have the potential for treating or preventing cancer or central nervous system diseases (Table 1).

Brain Penetration:

To determine whether the compound was able to cross the blood-brain barrier (BBB), the rats were administered with the test compound. Four hours after the administration, rats were sacrificed, blood and brain tissues were collected and the concentration of the test compound was analyzed. Brain permeation is defined as the ratio of the concentration of the compound in the brain tissue to the concentration of the compound in the plasma. P-glycoprotein is the blood-brain barrier efflux protein, which discharges the P-glycoprotein substrate out of the brain. The brain penetration of the compounds 1-48 of the present invention are all greater than 0.3, and they are not P-glycoprotein substrates and breast cancer resistance protein substrates, and then can cross the blood-brain barrier, so they have the potential to achieve effective blood drug concentration in the brain and be used to treat or prevent cancer brain metastasis, meningeal metastasis, brain cancer and other central nervous system diseases.

Example 7 Animal Model Data

In the efficacy experiment of SKOV3 tumor cell mouse subcutaneous animal model (FIG. 1), the drug was administered on the 30th day after the tumor cells were planted and the drug administration was lasted for four weeks. The second group of compound 1 was used as monotherapy, 10 mg/kg, oral dosing, twice a day, and the third group of compound 1 was used as monotherapy, 20 mg/kg, oral dosing, twice a day, compared to the first group of control group (without drug), both the second group and the third group showed good inhibition of tumor growth, with a dose-dependent and statistically significant efficacy. As shown in FIG. 1, some of the compounds described in the present invention have a good inhibitory effect on tumor growth that depends on VEGFR2. In the efficacy experiment of the PC-9Luc tumor cell mouse intracranial animal model (FIG. 2), the drug was administered on the 10^thday after the tumor cells were planted and the drug administration was lasted for three weeks. The second group of compound 1 was used as monotherapy, 10 mg/kg, oral dosing, twice a day; the third group of EGFR inhibitors (chemical name: (R)-6-[(3,3-difluoro-1-methylpiperidin-4-yl)oxy]-nitrogen-(3-ethynyl-2-fluorophenyl)-7-methoxyquinazolin-4-amine) was used as monotherapy, 3 mg/kg, oral dosing, twice a day; the fourth group of compound 1 combined with EGFR inhibitors. As shown in FIG. 2, compared with the first group of control group (without drug), the third group of EGFR inhibitor as monotherapy showed good inhibition on intracranial tumor growth, indicating that EGFR inhibitor (chemical name: (R)-6-[(3,3-difluoro-1-methylpiperidin-4-yl)oxy]-nitrogen-(3-ethynyl-2-fluorophenyl)-7-methoxyquinazoline-4-amine) can effectively cross the blood-brain barrier. Unexpectedly, in the fourth group, compound 1 and EGFR inhibitor in combination showed a synergistic effect in the brain. Compared with the second and third single-drug groups, the efficacy of the single drug was improved, and the efficacy was statistically significant, indicating that the compound of the present invention can effectively cross the blood-brain barrier. At the same time, the benefits of this synergistic effect were obvious, such as improving the efficacy of a single drug and minimizing toxic side effects of the second therapeutic agent or the compound of the present invention, improving efficacy, prolonging the time of acquiring drug resistance, improving the convenience of administration or use, and/or reducing the overall cost of compound products or formulations.
