Title of Invention : SALTS OF AMINOQUINAZOLINE DERIVATIVE AND USES THEREOF

[0001]
CROSS-REFERENCE TO RELATED APPLICATION
[0002]
This application claims priority and benefits of Chinese Patent Application No. 201611050237.6, filed with State Intellectual Property Office on 25 November 2016, the entire content of which is incorporated herein by reference.

FIELD

[0003]
The invention belongs to the field of medicine, and relates to salts of aminoquinazoline derivative and uses thereof, particularly relates to a salt of (E) -N- (4- (3-chloro-4-fluorophenyl) amino) -7- (methyloxy-D 3) -quinazolin-6-yl) -4- ( (4aR, 7aS) -tetra hydro-2H- [l, 4] dioxino [2, 3-c] pyrrole-6 (3H) -yl) butyl-2-enamide and uses thereof, and further relates pharmaceutical compositions containing the salt. The salt or the pharmaceutical compositions can be used as a tyrosine kinase inhibitor for the treatment and prevention of proliferative diseases.

BACKGROUND

[0004]
Protein kinases (PKs) represent a large class of proteins which play important roles in the control of cell function and the regulation of various cell diseases, and can be divided into two categories: protein tyrosine kinases (PTKs) and serine threonine kinases (STKs) . Protein tyrosine kinase is a kind of enzyme that can catalyze and transfer a phosphate group from ATP to a tyrosine residue of a protein substrate, which plays a role in normal cell growth. Many growth factor receptor proteins act through tyrosine kinases, which influence signals transduction, and then regulate cell growth. However, under certain conditions, these receptors mutate or overexpress, and become abnormal, which cause cell proliferation to be uncontrolled, lead to tumor growth, eventually lead to well-known disease-cancer. Growth factor receptor protein tyrosine kinase inhibitors play a role in the treatment of cancer and other disorders characterized by uncontrolled or abnormal cell growth by inhibiting the above phosphorylation process.
[0005]
An epidermal growth factor receptor (EGFR) is a receptor type tyrosine kinase that is widely distributed on the cell membranes of human body tissues, and is an oncogene analog of avian erythroblastic leukemia viral (v-erb-b) . EGFR/HER1/ErbB-1 and HER2 (human epidermal growth factor receptor-2) /ErbB-2/Teu/p185, HER3/ErbB-3, HER4/ErbB-4 and the like are grouped into the HER/ErbB family, and belong to protein tyrosine kinases (PTKs) . They are each a single polypeptide chain, and respectively encoded by genes located on different chromosomes. EGFR and the like overexpress in the epithelia-derived tumors such as squamous cell carcinoma of head and neck, mammary cancer, rectal cancer, ovarian cancer, prostate carcinoma, non-small cell lung cancer, and the like. Their expression is related to cancer cell proliferation and metastasis. Pan-HER tyrosine kinase inhibitors inhibit the activation of the HER-2 family by competitively with ATP binding to the intracellular kinase catalytic site, blocking the autophosphorylation of intracellular tyrosine and blocking tyrosine kinase activation, thereby play a therapeutic role by inhibiting cell cycle progression and accelerating apoptosis .
[0006]
An EGFR binds to a ligand, forms a dimer with the HER family subtype, and then binds to ATP to activate EGFR's own tyrosine kinase activity, causes autophosphorylation of several tyrosine sites in the intracellular kinase domain. Pan-HER tyrosine kinase inhibitors play an important role in inhibiting tumor growth by simultaneously acting on EGFR and HER2/4 and inhibiting the HER family activation.
[0007]
Studies have shown that Pan-HER tyrosine kinase irreversible inhibitors, in addition to an effective inhibition on EGFR, have an inhibition effect on HER2/4. These drugs that have irreversible inhibitory effects on the HER/ErbB family can improve drug activity, also reduce the generation of drug resistance, and have a significant inhibitory effect on Erlotinib-resistant H1975 cell line.
[0008]
The mutations of the EGFR gene often occurred in the Tyrosin kinase coding region (TK, 18-21 exon) , which are mainly drug-sensitive 19 exon deletion mutations and 21 exon point mutations, as well as a few 18 exon point mutations and 20 exon insertion mutations. T790M mutation is a point mutation in EGFR 20 exon, which is one of the more recognized drug resistance mechanisms. The main mechanism is that secondary mutation of threonine residue 790 region, the threonine residue converts into methionine (T790M) . The mutation leads to changes in EGFR structure, hinders the binding of EGFR to its inhibitors or greatly increases the affinity of EGFR and ATP, and the ATP affinity is restored to the EGFR wild level, which leads to resistance. Further studies have shown that pre-treatment EGFR mutant tumor samples also contain T790M mutation, which indicates that T790M mutation is not only related to drug resistance, but may also have carcinogenic potential.
[0009]
Irreversible inhibitors can covalently bind to EGFR tyrosine kinases, so that the drugs can act on the entire process of the epidermal growth factor signal transduction pathway and increase the blocking efficiency of the drugs. Many clinical studies have shown that the current development of irreversible inhibitors can against T790M mutation, which can overcome the resistance caused by T790M.
[0010]
Patent applications WO 2014/177038 and CN 104119350 discloses aminoquinazoline tyrosine kinase inhibitors with irreversible inhibition effect on Pan-HER, wherein the compound (E) -N- (4- (3-chloro-4-fluorophenyl) amino) -7- (methyloxy-D 3) -quinazolin-6-yl) -4- ( (4aR, 7aS) -tetra hydro-2H- [l, 4] dioxino [2, 3-c] pyrrole-6 (3H) -yl) butyl-2-enamide (i.e. compound (I) ) has an excellent antitumor effect. It can reduce the generation of drug resistance and also have good tolerance.
[0011]
[0012]
Drug polymorphism is a common phenomenon in drug development, which is an important factor affecting the quality of drugs. Different crystal forms of the same drug may have significant differences in appearance, solubility, melting point, dissolution, bioavailability, etc., and may have different effects on the stability, bioavailability and efficacy of the drug. Therefore, the drug polymorphism should be fully considered in drug research and development.
[0013]
Amorphism is a form of polymorphism occurred in substance, which is a non-crystal state. The various physical and chemical properties and clinical efficacy characteristics of amorphous drugs are often different from the general crystalline drugs. Therefore, the in-depth study of amorphous substances also has great significance in the solid drug polymorphic study.
[0014]

DEFINITIONS AND GENERAL TERMINOLOGY
[0080]
Unless otherwise indicated, all technical and scientific terminology used in the present invention have the same meaning as commonly understood by those of ordinary skill in the art to which this invention pertains. All patents and publications referred to herein are incorporated by reference in their entirety. Although any methods and materials similar or identical to those described herein may be used in the practice or testing of the invention, but the methods, apparatus and materials described in the invention are preferred.
[0081]
"Pharmaceutically acceptable acid addition salt" is a salt formed by compound (I) with a pharmaceutically acceptable non-toxic acid, including but not limited to the salt formed by compound (I) with any of various organic or inorganic acids.
[0082]
"An acid addition salt of compound (I) " means a salt formed by reacting compound (the free base) (I) with any of various suitable organic or inorganic acids, including, but not limited to, hydrochloride, hydrobromide, sulfate, maleate, benzenesulfonate, p-toluenesulfonate, naphthalenesulfonate, oxalate, methanesulfonate and the like. Wherein, the "acid addition salt of compound (I) ” includes an amorphous or a crystalline form of the salt, including its solvate form (e.g., a hydrate form) , and also including its polymorphism. For example, dimesylates of compound (I) include its amorphous forms, various crystalline forms, various solvates, various hydrates, and also include polymorphic forms of such salts.
[0083]
"Crystal form" or "crystalline form" refers to a solid having a highly regular chemical structure, including, but not limited to, a mono-or multi-component crystal, and/or a polymorphism of compound, a solvate, a hydrate, a clathrate, a eutectic, a salt, a solvate of salt, a hydrate of salt. The crystalline form of the material can be obtained by a number of methods known in the art. Such methods include, but not limited to, melt crystallization, melt cooling, solvent crystallization, crystallization in defined space, for example, in nanopores or capillaries, on a surface or template, for example, on a polymer, in the presence of additives such as co-crystallization counterions, removing solvent, dehydration, rapid evaporation, rapid cooling, slow cooling, vapor diffusion, sublimation, reaction crystallization, anti-solvent addition, grinding and solvent drop milling.
[0084]
"Amorphism" or "amorphous form" refers to a substance formed by particle (such as molecule, atom, ion) of a substance arranged in a non-periodic manner in three-dimensional space, which is characterized by an X-ray powder diffraction pattern with no sharp peaks. Amorphism is a special physical form of solid substance, and its ordered structural characteristics in a part of amorphous substance imply that there are innumerable links between amorphous substance and crystal substance. The amorphous form of a substance can be obtained by a number of methods known in the art. Such methods include, but not limited to, quenching, anti-solvent flocculation, ball milling, spray drying, freeze drying, wet granulation and solid dispersion techniques.
[0085]
"Solvent" refers to a substance (typically a liquid) that is capable of completely or partially dissolving another substance (typically a solid) . Solvents for use in the practice of this invention include, but not limited to, water, acetic acid, acetone, acetonitrile, benzene, chloroform, carbon tetrachloride, dichloromethane, dimethylsulfoxide, 1, 4-dioxane, ethanol, ethyl acetate, butanol, t-butanol, N, N-dimethylacetamide, N, N-dimethylformamide, formamide, formic acid, heptane, hexane, isopropanol, methanol, methyl ethyl ketone, mesitylene, nitromethane, polyethylene glycol, propanol, pyridine, tetrahydrofuran, toluene, xylene, or a combination thereof, and the like.
[0086]
"Anti-solvent" refers to a fluid that promotes the precipitation of a product (or product precursor) from a solvent. The anti-solvent comprise a cold gas, or a fluid that promotes the precipitation by chemical reaction or reduces the solubility of the product in the solvent; it can be the same liquid as the solvent but at a different temperature, or it can be a liquid different from the solvent.
[0087]
"Solvate" refers to a compound having a solvent on a surface, in a lattice or on a surface and in a lattice of the compound. The solvent can be water, acetic acid, acetone, acetonitrile, benzene, chloroform, carbon tetrachloride, dichloromethane, dimethylsulfoxide, 1, 4-dioxane, ethanol, ethyl acetate, butanol, t-butanol, N, N-dimethylacetamide, N, N-dimethylformamide, formamide, formic acid, heptane, hexane, isopropanol, methyl ethyl ketone, methyl pyrrolidone, mesitylene, nitromethane, polyethylene glycol, propanol, pyridine, tetrahydrofuran, toluene, xylene, or a combination thereof, and the like. A specific example of the solvate is a hydrate in which the solvent on the surface, in the lattice or on the surface and in the lattice is water. On the surface, in the lattice or on the surface and in the lattic of the substance, the hydrate may or may not have any solvent other than water.
[0088]
The stoichiometric solvate has a fixed ratio of the solvent molecule to the compound molecule. This is typically due to the bonding interaction between the solvent and the compound molecules. In non-stoichiometric solvates, the solvent does not exist at a fixed ratio to the compound molecule and its content can often vary. In non-stoichiometric solvates, the solvent often exists in the void space or channel within the lattice. The stoichiometric hydrate has a fixed ratio of the water molecule to the compound molecule. This is typically due to the bonding interaction between the water and the compound molecules. In non-stoichiometric hydrate, the water does not exist at a fixed ratio to the compound molecule and its content can often vary. In non-stoichiometric hydrate, the water is often present in the void space or channel within the lattice.
[0089]
The acid addition salts disclosed herein or their crystalline or amorphous forms are preferably present in a separate and substantially pure form.
[0090]
The present invention also relates to physical properties of the acid addition salts disclosed herein or their crystalline or amorphous in a solid state. These properties can be influenced by controlling the condition of obtaining salt or crystalline or amorphous in solid form. The physical properties of the solid state include, for example, the flowability of the solid that has been ground. The mobility affects the complexity in the process of handling of the substance into drug. When the powdered particles do not flow easily, the preparation specialist has to consider the fact that it is necessary to use a glidant such as colloidal silica, talc, starch or trivalent calcium phosphate in the development of tablets or capsules.
[0091]
Another important solid state property of the pharmaceutical compound is its dissolution rate in aqueous liquid or the bioavailability of the drug. The rate of dissolution of an active ingredient in a patient's stomach fluid can have therapeutic consequences since it imposes an upper limit on the rate at which an orally-administered active ingredient can reach the patient's bloodstream.
[0092]
For example, in the case of dissolution rate and bioavailability, different crystalline forms or amorphous forms of the same drug may vary widely in such important pharmaceutical properties. Likewise, different crystalline or amorphous forms may have different processing properties, such as hygroscopicity, fluidity, etc., which may affect their suitability as an active drug for commercial preparation.
[0093]
In the preparation of syrups, elixirs and other liquid medicaments, the rate of dissolution should also be taken into account. The solid state of the compound can also affect its behavior against compression and storage stability.
[0094]
These physical properties are influenced by molecular conformation and orientation in the unit cell, and the conformation and orientation of the molecules in the unit cell determine the specific polymorphism of the substance.
[0095]
Crystal form or amorphism can be identified by a variety of technical means, such as X-ray powder diffraction (XRPD) , infrared absorption spectroscopy (IR) , melting point method, differential scanning calorimetry (DSC) , thermogravimetric analysis (TGA) , Nuclear magnetic resonance, Raman spectroscopy, X-ray single crystal diffraction, dissolution calorimetry, scanning electron microscopy (SEM) , quantitative analysis, solubility and dissolution rate.
[0096]
X-ray powder diffraction (XRPD) can detect changes in crystal form, crystallinity, crystal state and other information, which is a common mean for identifying crystalline form. The peak position of the XRPD pattern primarily depends on the structure of the crystalline form and is relatively insensitive to the experimental details, and its relative peak height depends on many factors associated with sample preparation and instrument geometry. Thus, in some embodiments, the crystalline form disclosed herein is characterized by an XRPD pattern having certain peak positions, which is substantially as shown in the XRPD pattern provided in the drawings disclosed herein. At the same time, the 2θ of the XRPD pattern measured may exist an experimental error. The measurement of 2θ of the XRPD pattern may be slightly different because of the different instruments and the different samples. Therefore, the value of 2θ could not be regarded as absolute. According to the condition of the instrument used in this test, the diffraction peak has an error margin of ± 0.2°.
[0097]
Differential Scanning Calorimetry (DSC) is a technique of measuring the energy difference between a sample and an inert reference (commonly used α-Al 2O 3) which varies with temperature by continuously heating or cooling under program control. The endothermic peak height of the DSC thermogram depends on many factors associated with sample preparation and instrument geometry, while the peak position is relatively insensitive to experimental details. Thus, in some embodiments, the crystalline form disclosed herein is characterized by a DCS thermogram having certain characteristic peak positions, which is substantially as shown in the DCS thermogram provided in the drawings disclosed herein. At the same time, the DCS thermogram measured may be existed an experimental error. The peak position and peak value of DCS thermogram may be slightly different because of the different instruments and the different samples. Therefore, the peak position or the peak value of the DSC endothermic peak could not be regarded as absolute. According to the condition of the instrument used in this test, the melting peak has an error margin of ± 3℃.
[0098]
Differential scanning calorimetry (DSC) can also be used to detect and analyse whether there is a crystal transformation or mixed grain phenomenon in crystalline form.
[0099]
Thermogravimetric analysis (TGA) is a technique for measuring the quality of a substance which varies with temperature under the control of a program. It is suitable for examining the process of the solvent loss or the samples sublimation and decomposition. It can be presumed that the crystal contains crystal water or crystallization solvent. The quality changes shown on the TGA curve depend on a number of factors, such as the sample preparation and the instrument, and the like. The quality changes obtained from TGA test may be slightly different between the different instruments and between the different samples. The dimaleate having crystalline form A disclosed herein is characterized by the weight loss of the TGA test is about 0.48%and the TGA pattern is substantially as shown in figure 10. According to the condition of the instrument used in this test, there exists a ± 0.1%error margin of the quality change.

[0102]
The "peak" refers to a feature that a person skilled in the art can recognize as not attributable to background noise when referring to a spectrum or/and data that appears in the figure.
[0103]
The invention relates to all kinds of new crystalline forms of the acid addition salts of (E) -N- (4- (3-chloro-4-fluorophenyl) amino) -7- (methyloxy-D 3) -quinazolin-6-yl) -4- ( (4aR, 7aS) -tetrahydro-2H- [l, 4] dioxino [2, 3-c] pyrrole-6 (3H) -yl) butyl-2-enamide, which exist in a substantially pure crystalline form.

The amorphism can be prepared by spray drying.
[0105]
"Substantially pure" means that a crystalline form is substantially free of another or more crystalline forms, that means the purity of the crystalline form is at least 80%, or at least 85%, or at least 90%, or at least 93%, or at least 95%, or at least 98%, or at least 99%, or at least 99.5%, or at least 99.6%, or at least 99.7%, or at least 99.8%, or at least 99.9%, or crystalline form containing other crystalline form.

[0107]
"Relative strength" (or "relative peak height" ) means the ratio of the intensity of the other peak to the intensity of the first strong peak when the intensity of the first strong peak in all the diffraction peaks of the X-ray powder diffraction pattern (XRD) is 100%.
[0108]
In the context of the present invention, when used or whether or not used the word, such as "about" , it means that within a given value or range of 10%or less, appropriately within 5%, especially within 1%. Or, for those of ordinary skilled in the art, the terminology "about" means within an acceptable standard error range of the mean value. When a number with an N value is disclosed, any number within N +/-1%, N +/-2%, N +/-3%, N +/-5%, N +/-7%, N +/-8%, or N +/-10%will be disclosed clearly, wherein "+/-" means plus or minus.
[0109]
Unless otherwise stated, the organic acids depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, geometric (or conformational) ) forms of the structure; for example, the R and S configurations for each asymmetric center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric isomers, diastereomeric isomers, or geometric isomers (or conformational isomers) mixtures of the organic acids in the present invention are within the scope disclosed herein.
[0110]
Unless otherwise stated, all tautomeric forms of the organic acid disclosed herein are within the scope of the invention. Additionally, unless otherwise stated, structures depicted herein are also meant to include organic acid that differ only in the presence of one or more isotopically enriched atoms.
[0111]
The use of stereochemical definitions and conventions in the present invention is generally referred to the following: S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., "Stereochemistry of Organic Compounds" , John Wiley&Sons, Inc., New York, 1994. The organic acid disclosed herein may contain asymmetric or chiral centers, and therefore exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the organic acid disclosed herein, including, but not limited to, diastereomers, enantiomers and atropisomers, as well as mixtures thereof such as racemic mixtures, form part of the present invention. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L, or R and S, are used to denote the absolute configuration of the molecule about its chiral center (s) . The prefixes d and 1 or (+) and (-) are employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or l meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50: 50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terminology "racemic mixture" or "racemate" refers to an equimolar mixture of two enantiomeric species, devoid of optical activity.
[0112]
In the present invention, "room temperature" means that the temperature is from about 10℃ to about 40℃. In some embodiments, "room temperature" refers to a temperature of from about 20℃ to about 30℃; in other embodiments, "room temperature" refers to 20℃, 22.5℃, 25℃, 27.5℃, and the like.
