[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the benefit of Chinese Patent Application No. 201510161674.4, filed on April 7, 2015, the entire contents of which are hereby incorporated by reference. Technical Field
[0003] The present invention belongs to the field of medical technology, and specifically relates to a class of tyrosine kinase inhibitors or pharmaceutically acceptable salts thereof, and a pharmaceutical composition comprising the tyrosine kinase inhibitor. Background Art
[0004] Protein tyrosine kinases are a class of enzymes that catalyze the transfer of phosphate groups from ATP to tyrosine residues located on protein substrates, which play a role in normal cell growth. Many growth factor receptor proteins act through tyrosine kinases and affect signals through this process, thereby regulating cell growth. For example, FGFR (Fibroblast growth factor receptor), VEGFR (Vascular endothelial growth factor receptor) and PDGFR (Platelet-derived growth factor receptor). However, under certain conditions, these receptors either mutate or are overexpressed, become abnormal, cause uncontrolled cell proliferation, lead to tumor growth, and ultimately cause the well-known disease - cancer. Growth factor receptor protein tyrosine kinase inhibitors play a role in treating cancer and other diseases characterized by uncontrolled or abnormal cell growth by inhibiting the above-mentioned phosphorylation process.
[0005] Uncontrolled angiogenesis is a hallmark of cancer. In 1971, Dr. Judah Folkman proposed that tumor growth depends on angiogenesis, (see Folkman, New England Journal of Medicine, 285: 1182-86 (1971). According to Dr. Judah Folkman, tumors can only grow to a certain size without growing additional blood vessels to nourish the tumor. In its simplest form, it is pointed out that once tumor "survival" has occurred, each increase in the tumor cell population must be accompanied by the increase of new capillaries converging on the tumor. The "survival" of a tumor as currently understood refers to the prevascular phase of tumor growth, in which a tumor cell population occupying a volume of several cubic millimeters and not exceeding a few million cells can survive on the existing host microvasculature.
[0006] It has been shown that tumors can be treated by inhibiting angiogenesis rather than inhibiting the proliferation of tumor cells themselves. Angiogenesis has been associated with a large number of different types of cancer, including solid tumors and blood-borne tumors. Solid tumors associated with angiogenesis include, but are not limited to, rhabdomyosarcoma, retinoblastoma, Ewing's sarcoma, neuroblastoma, and osteosarcoma. Angiogenesis is associated with breast cancer, prostate cancer, lung cancer, and colon cancer. Angiogenesis is also associated with blood-borne tumors, such as leukemia, lymphoma, multiple myeloma, and any of a variety of acute or chronic myeloid neoplastic diseases, in which unrestricted proliferation of white blood cells occurs, usually accompanied by anemia, impaired blood coagulation, and enlargement of lymph nodes, liver, and spleen. It is also believed that angiogenesis plays a role in bone marrow abnormalities that cause leukemia, lymphoma, and multiple myeloma.
[0007] Angiogenesis plays a major role in the metastasis of cancer, and if angiogenic activity can be inhibited or eliminated, then tumors will not grow despite their presence. In disease states, preventing angiogenesis can reduce the damage caused by the invasion of new microvasculature. Therapies directed at the control of angiogenic processes may lead to the elimination or alleviation of these diseases.
[0008] Among them, the research on inhibiting angiogenesis by FGFR (Fibroblast growth factor receptor), VEGFR (Vascular endothelial growth factor receptor) and PDGFR (Platelet-derived growth factor receptor) inhibitors is becoming more and more mature. Summary of the invention
[0009] The present invention provides a tyrosine kinase inhibitor or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition comprising the tyrosine kinase inhibitor.

[0055] Definition and Description
[0056] Unless otherwise specified, the following terms and phrases used herein are intended to have the following meanings. A particular term or phrase should not be considered to be uncertain or unclear in the absence of a special definition, but should be understood according to its ordinary meaning. When a trade name appears in this article, it is intended to refer to its corresponding commercial product or its active ingredient.
[0057] C 1-7 Selected from C1, C2, C3, C4, C5, C6 or C7; 3-6 members are selected from 3, 4, 5 or 6 members.
[0058] The term "pharmaceutically acceptable" as used herein refers to those compounds, materials, compositions and / or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and animals without excessive toxicity, irritation, allergic response or other problems or complications, commensurate with a reasonable benefit / risk ratio.
[0059] The term "pharmaceutically acceptable salt" refers to salts of compounds of the invention, prepared from compounds of the invention having specific substituents with relatively nontoxic acids or bases. When the compounds of the invention contain relatively acidic functional groups, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of base in a pure solution or a suitable inert solvent. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino or magnesium salts or similar salts. When the compounds of the invention contain relatively basic functional groups, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of acid in a pure solution or a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include inorganic acid salts, such as hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, hydrogen phosphate, dihydrogen phosphate, sulfuric acid, hydrogen sulfate, hydroiodic acid, phosphorous acid, etc.; and organic acid salts, such as acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-toluenesulfonic acid, citric acid, tartaric acid and methanesulfonic acid and the like; also include salts of amino acids (such as arginine, etc.), and salts of organic acids such as glucuronic acid (see Berge et al., "Pharmaceutical Salts", Journal of Pharmaceutical Science 66: 1-19 (1977)). Certain specific compounds of the present invention contain basic and acidic functional groups, and thus can be converted into either base or acid addition salts.
[0060] Preferably, the neutral form of the compound is regenerated by contacting the salt with a base or acid in a conventional manner and isolating the parent compound. The parent form of the compound differs from its various salt forms in certain physical properties, such as solubility in polar solvents.
[0061] As used herein, "pharmaceutically acceptable salts" are derivatives of the compounds of the invention, wherein the parent compound is modified by salification with an acid or alkali. Examples of pharmaceutically acceptable salts include, but are not limited to, inorganic or organic acid salts of bases such as amines, alkali or organic salts of acid radicals such as carboxylic acids, and the like. Pharmaceutically acceptable salts include conventional non-toxic salts or quaternary ammonium salts of the parent compound, such as salts formed with non-toxic inorganic or organic acids. Conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 2-acetoxybenzoic acid, 2-hydroxyethanesulfonic acid, acetic acid, ascorbic acid, benzenesulfonic acid, benzoic acid, bicarbonate, carbonic acid, citric acid, edetic acid, ethanedisulfonic acid, ethanesulfonic acid, fumaric acid, glucoheptose, gluconic acid, glutamic acid, glycolic acid, hydrobromic acid, hydrochloric acid, hydroiodide, hydroxy, hydroxynaphthalene, isethionic acid, lactic acid, lactose, dodecylsulfonic acid, maleic acid, malic acid, mandelic acid, methanesulfonic acid, nitric acid, oxalic acid, pamoic acid, pantothenic acid, phenylacetic acid, phosphoric acid, polygalacturonic acid, propionic acid, salicylic acid, stearic acid, acetic acid, succinic acid, sulfamic acid, p-aminobenzenesulfonic acid, sulfuric acid, tannin, tartaric acid, and p-toluenesulfonic acid.
[0062] The pharmaceutically acceptable salts of the present invention can be synthesized by conventional chemical methods from parent compounds containing acid radicals or bases. Generally, such salts are prepared by reacting these compounds in free acid or base form with a stoichiometric amount of an appropriate base or acid in water or an organic solvent or a mixture of the two. Generally, non-aqueous media such as ether, ethyl acetate, ethanol, isopropanol or acetonitrile are preferred.
[0063] In addition to the form of salts, compounds provided by the present invention also exist in prodrug forms. Prodrugs of compounds described herein easily undergo chemical changes under physiological conditions to be converted into compounds of the present invention. In addition, prodrugs can be converted to compounds of the present invention by chemical or biochemical methods in an in vivo environment.
[0064] Some compounds of the present invention may exist in non-solvated form or solvated form, including hydrate form. Generally speaking, solvated form is suitable with non-solvated form, all included in the scope of the present invention. Some compounds of the present invention may exist in polycrystalline or amorphous form.
[0065] Certain compounds of the present invention may possess asymmetric carbon atoms (optical centers) or double bonds. Racemates, diastereomers, geometric isomers and individual isomers are all within the scope of the present invention.
[0066] The graphic representations of racemic, ambiscalemic and scalemic or enantiomerically pure compounds herein are from Maehr, J. Chem. Ed. 1985, 62: 114-120. 1985, 62: 114-120. Unless otherwise indicated, wedge-shaped bonds and dashed bonds are used to represent the absolute configuration of a stereocenter. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, they are intended to include both E and Z geometric isomers unless otherwise indicated. Likewise, all tautomeric forms are intended to be within the scope of the present invention.
[0067] The compounds of the present invention may exist in specific geometric or stereoisomeric forms. The present invention contemplates all such compounds, including cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, and racemic mixtures and other mixtures thereof, such as enantiomerically or diastereomerically enriched mixtures, all of which are within the scope of the present invention. Additional asymmetric carbon atoms may be present in substituents such as alkyl. All of these isomers and their mixtures are included within the scope of the present invention.
[0068] Optically active (R)- and (S)-isomers and D and L isomers can be prepared by chiral synthesis or chiral reagents or other conventional techniques. If one enantiomer of a compound of the present invention is desired, it can be prepared by asymmetric synthesis or derivatization with a chiral auxiliary, wherein the resulting diastereomeric mixture is separated and the auxiliary group is cleaved to provide the pure desired enantiomer. Alternatively, when the molecule contains a basic functional group (such as an amino group) or an acidic functional group (such as a carboxyl group), a diastereomeric salt is formed with an appropriate optically active acid or base, and then the diastereoisomers are separated by fractional crystallization or chromatography as is known in the art, and then the pure enantiomer is recovered. In addition, the separation of enantiomers and diastereomers is usually accomplished by using chromatography, which employs a chiral stationary phase and is optionally combined with a chemical derivatization method (e.g., carbamates are generated from amines).
[0069] The compounds of the invention may contain unnatural proportions of atomic isotopes on one or more of the atoms that make up the compound. For example, the compounds may be labeled with radioactive isotopes, such as tritium ( 3 H), iodine-125( 125 I) or C-14( 14 C) All isotopic variations of the compounds of the present invention, whether radioactive or not, are included within the scope of the present invention.
[0070] The term "pharmaceutically acceptable carrier" refers to any preparation or carrier medium that can deliver an effective amount of the active substance of the present invention, does not interfere with the biological activity of the active substance, and has no toxic side effects on the host or patient. Representative carriers include water, oil, vegetables and minerals, cream bases, lotion bases, ointment bases, etc. These bases include suspending agents, viscosity enhancers, transdermal enhancers, etc. Their preparations are well known to those skilled in the art of cosmetics or topical drugs. For additional information about the carrier, reference can be made to Remington: The Science and Practice of Pharmacy, 21st Ed., Lippincott, Williams & Wilkins (2005), the contents of which are incorporated herein by reference.
[0071] The term "excipient" generally refers to a carrier, diluent and / or vehicle required to formulate an effective pharmaceutical composition.
[0072] With respect to a drug or pharmacologically active agent, the term "effective amount" or "therapeutically effective amount" refers to a sufficient amount of a drug or agent that is non-toxic but can achieve the desired effect. For oral dosage forms of the present invention, an "effective amount" of an active substance in a composition refers to the amount required to achieve the desired effect when used in combination with another active substance in the composition. The determination of the effective amount varies from person to person, depending on the age and general condition of the recipient, and also on the specific active substance. The appropriate effective amount in each case can be determined by a person skilled in the art based on routine experiments.
[0073] The terms "active ingredient," "therapeutic agent," "active substance," or "active agent" refer to a chemical entity that is effective in treating a target disorder, disease, or condition.
[0074] The term "substituted" means that any one or more hydrogen atoms on a particular atom are replaced by a substituent, including deuterium and hydrogen variants, as long as the valence state of the particular atom is normal and the substituted compound is stable. When the substituent is a keto group (i.e., =O), it means that two hydrogen atoms are replaced. Keto substitution does not occur on aromatic groups. The term "optionally substituted" means that it may be substituted or not substituted, and unless otherwise specified, the type and number of substituents can be arbitrary on the basis of chemical achievable.
[0075] When any variable (e.g., R) occurs more than once in a compound's composition or structure, its definition at each occurrence is independent. Thus, for example, if a group is substituted with 0-2 Rs, the group may be optionally substituted with up to two Rs, and each occurrence of R is an independent choice. In addition, combinations of substituents and / or variants thereof are permitted only if such combinations result in stable compounds.
[0076] When one of the variables is selected from a single bond, it means that the two groups it connects are directly connected. For example, when L in ALZ represents a single bond, it means that the structure is actually AZ.
[0077] When a substituent's bond can cross-link to two atoms on a ring, the substituent can be bonded to any atom on the ring. When a substituent is listed without indicating the atom through which it is bonded to the compound included in the chemical formula but not specifically mentioned, the substituent can be bonded through any atom. Combinations of substituents and / or their variants are permitted only if such combinations result in stable compounds. For example, the structural unit It means that it can be substituted at any position on the cyclohexyl group or the cyclodiene.
[0078] Substituents of alkyl and heteroalkyl radicals are generally referred to as "alkyl substituents" and may be selected from, but are not limited to, one or more of the following groups: -R', -OR', =O, =NR', =N-OR', -NR'R", -SR', halogen, -SiR'R"R"', OC(O)R', -C(O)R', -C02R', -CONR'R", -OC(O)NR'R", -NR"C(O)R', NR'C(O)NR"R"', -NR"C(O)2R', -NR""'-C(NR'R"R'")=NR"", NR""C(NR'R")=NR'", -S(O)R', -S(O)2R', -S(O)2NR'R", NR"S02R', -CN, -NO2, -N- 3. -CH(Ph)2 and fluoro(C1-C4)alkyl, the number of substituents is 0 to (2m'+1), where m' is the total number of carbon atoms in such radicals. R', R", R"', R"" and R""' are each independently preferably hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1 to 3 halogens), substituted or unsubstituted alkyl, alkoxy, thioalkoxy or aralkyl. When the compounds of the present invention include more than one R group, for example, each R group is independently selected, as are each of these groups when more than one R', R", R"', R"" and R""' groups are present. When R' and R" are attached to the same nitrogen atom, they may be combined with the nitrogen atom to form a 5-, 6- or 7-membered ring. For example, -NR'R" is intended to include but is not limited to 1-pyrrolidinyl and 4-morpholinyl. Based on the above discussion on substituents, those skilled in the art will understand that the term "alkyl" is intended to include groups consisting of carbon atoms bonded to non-hydrogen groups, such as haloalkyl (e.g., -CF3, -CH2CF3) and acyl (e.g., -C(O)CH3, -C(O)CF3, -C(O)CH2OCH3, etc.).
[0079] Similar to the substituents described for alkyl radicals, aryl and heteroaryl substituents are generally referred to as "aryl substituents" and are selected from, for example, -R', -OR', -NR'R", -SR', -halogen, -SiR'R"R"', OC(O)R', -C(O)R', -C02R', -CONR'R", -OC(O)NR'R", -NR"C(O)R', NR'C(O)NR"R"', -NR"C(O)2R', -NR""', -C(NR'R"R'")=NR"", NR""C(NR'R")=NR'", -S(O)R', -S(O)2R', -S(O)2NR'R", NR ”SO2R', -CN, -NO2, -N3, -CH(Ph)2, fluoro(C1-C4)alkoxy and fluoro(C1-C4)alkyl, etc., the number of substituents is between 0 and the total number of open valences on the aromatic ring; wherein R', R", R"', R"" and R""' are independently preferably selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl and substituted or unsubstituted heteroaryl. When the compounds of the present invention include more than one R group, for example, each R group is independently selected, as are each of these groups when there are more than one R', R", R"', R"" and R""' groups.
[0080] Two substituents on adjacent atoms of an aryl or heteroaryl ring may be optionally substituted with a substituent of the general formula -TC(O)-(CRR')qU-, wherein T and U are independently selected from -NR-, -O-, CRR'- or a single bond, and q is an integer from 0 to 3. Alternatively, two substituents on adjacent atoms of an aryl or heteroaryl ring may be optionally substituted with a substituent of the general formula -A(CH2)rB-, wherein A and B are independently selected from -CRR'-, -O-, -NR-, -S-, -S(O)-, S(O)2-, -S(O)2NR'- or a single bond, and r is an integer from 1 to 4. Optionally, a single bond on the new ring thus formed may be replaced with a double bond. Alternatively, two substituents on adjacent atoms of the aryl or heteroaryl ring may be optionally substituted with a substituent of the general formula -A(CH2)rB-, wherein s and d are independently selected from integers of 0 to 3, and X is -O-, -NR', -S-, -S(O)-, -S(O)2- or -S(O)2NR'-. The substituents R, R', R" and R'" are independently selected from hydrogen and substituted or unsubstituted (C1-C6)alkyl.
[0081] Unless otherwise specified, the term "halogen" or "halogen" by itself or as part of another substituent represents a fluorine, chlorine, bromine or iodine atom. In addition, the term "haloalkyl" is intended to include monohaloalkyl and polyhaloalkyl. For example, the term "halo (C1-C4) alkyl" is intended to include but is not limited to trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl and 3-bromopropyl, etc.
[0082] Examples of haloalkyl groups include, but are not limited to, trifluoromethyl, trichloromethyl, pentafluoroethyl, and pentachloroethyl. "Alkoxy" represents an alkyl group as defined above with a specified number of carbon atoms attached through an oxygen bridge. 1-6 Alkoxy includes C1, C2, C3, C4, C5 and C6 alkoxy. Examples of alkoxy include, but are not limited to, methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, sec-butoxy, tert-butoxy, n-pentoxy and S-pentoxy. "Cycloalkyl" includes saturated cyclic groups, such as cyclopropyl, cyclobutyl or cyclopentyl. 3-7 cycloalkyl includes C3, C4, C5, C6 and C7 cycloalkyl. "Alkenyl" includes hydrocarbon chains of straight or branched configuration, wherein one or more carbon-carbon double bonds are present at any stable site on the chain, such as vinyl and propenyl.
[0083] The term "halo" or "halogen" refers to fluorine, chlorine, bromine and iodine.
[0084] Unless otherwise specified, the term "hetero" means a heteroatom or heteroatom group (i.e., an atom group containing heteroatoms), including atoms other than carbon (C) and hydrogen (H) and atom groups containing these heteroatoms, for example, including oxygen (O), nitrogen (N), sulfur (S), silicon (Si), germanium (Ge), aluminum (Al), boron (B), -O-, -S-, =O, =S, -C(=O)O-, -C(=O)-, -C(=S)-, -S(=O), -S(=O)2-, and optionally substituted -C(=O)N(H)-, -N(H)-, -C(=NH)-, -S(=O)2N(H)- or -S(=O)N(H)-.
[0085] Unless otherwise specified, "ring" means substituted or unsubstituted cycloalkyl, heterocycloalkyl, cycloalkenyl, heterocycloalkenyl, cycloalkynyl, heterocycloalkynyl, aryl or heteroaryl. The so-called ring includes a monocyclic, linked ring, spirocyclic, cyclic or bridged ring. The number of atoms on the ring is usually defined as the number of members of the ring, for example, "5-7 membered ring" means 5 to 7 atoms arranged around. Unless otherwise specified, the ring optionally contains 1 to 3 heteroatoms. Therefore, "5-7 membered ring" includes, for example, phenyl, pyridine and piperidinyl; on the other hand, the term "5-7 membered heterocycloalkyl ring" includes pyridinyl and piperidinyl, but does not include phenyl. The term "ring" also includes a ring system containing at least one ring, each of which "rings" independently meets the above definition.
[0086] Unless otherwise specified, the term "heterocycle" or "heterocyclyl" means a stable monocyclic, bicyclic or tricyclic ring containing a heteroatom or heteroatom group, which may be saturated, partially unsaturated or unsaturated (aromatic), and which contains carbon atoms and 1, 2, 3 or 4 ring heteroatoms independently selected from N, O and S, wherein any of the above heterocycles may be fused to a benzene ring to form a bicyclic ring. Nitrogen and sulfur heteroatoms may be optionally oxidized (i.e., NO and S(O)p). Nitrogen atoms may be substituted or unsubstituted (i.e., N or NR, where R is H or other substituents as defined herein). The heterocycle may be attached to any heteroatom or carbon atom side group to form a stable structure. The heterocycles described herein may be substituted at the carbon or nitrogen position if the resulting compound is stable. Nitrogen atoms in the heterocycle are optionally quaternized. A preferred embodiment is that when the total number of S and O atoms in the heterocycle exceeds 1, these heteroatoms are not adjacent to each other. Another preferred embodiment is that the total number of S and O atoms in the heterocycle does not exceed 1. As used herein, the term "aromatic heterocyclic group" or "heteroaryl" means an aromatic ring of a stable 5-, 6-, 7-membered monocyclic or bicyclic or 7-, 8-, 9- or 10-membered bicyclic heterocyclic group, which contains carbon atoms and 1, 2, 3 or 4 ring heteroatoms independently selected from N, O and S. The nitrogen atom can be substituted or unsubstituted (i.e., N or NR, wherein R is H or other substituents defined herein). The nitrogen and sulfur heteroatoms can be optionally oxidized (i.e., NO and S(O)p). It is worth noting that the total number of S and O atoms on the aromatic heterocyclic ring does not exceed 1. Bridged rings are also included in the definition of heterocycles. A bridged ring is formed when one or more atoms (i.e., C, O, N or S) connect two non-adjacent carbon atoms or nitrogen atoms.
