Background

Apoptosis signal-regulating kinase 1 (ASK 1) is one of the members of the mitogen-activated protein kinase kinase kinase (MAP 3Ks) family, also known as mitogen-activated protein kinase kinase kinase kinase kinase 5(mitogen-activated protein kinase kinase 5, MAPKK 5, MAP3K5), and comprises 1375 amino acid residues constituting 11 kinase sub-domains and a serine/threonine kinase region located in the middle of the molecule flanking the N-terminal and C-terminal coiled coil regions (Wa. J.biol. chem.1996,271, 31607-31611; Ichij. science.1997,275, 90-94; Tobium et al. Biochem.Biophys.Res. 905, Commun.239, 910). ASK1 can be activated by a variety of stimuli, such as: oxidative stress, active oxygen, endotoxin, tumor necrosis factor-alpha, endoplasmic reticulum stress, intracellular calcium ion concentration, and the like.

ASK1 has been shown to not only regulate cell death, but also play an important role in cellular activities such as cytokine responses, cell differentiation, innate immune responses, and the like. Modulating the activity of ASK1 can treat or prevent a variety of diseases including neurodegenerative diseases, cardiovascular diseases, inflammation, autoimmune diseases, and metabolic disorders. ASK1 modulators have great potential, especially in the treatment of cardiorenal diseases (including kidney disease, diabetic nephropathy and chronic kidney disease), fibrotic diseases (including pulmonary fibrosis and renal fibrosis), respiratory diseases (including chronic obstructive pulmonary obstruction and acute lung injury) and liver diseases.

Data indicate that liver disease has now become one of the leading causes of human death. Liver diseases are generally classified into acute and chronic liver diseases according to the duration of the disease. Liver disease may be caused by infection, injury, medication, poisoning, drinking, poor food intake, abnormal accumulation of normal components in the blood, autoimmunity, genetic defects, or other unknown factors. Common liver diseases include chronic liver disease, metabolic liver disease, hepatic fibrosis, primary sclerosing cholangitis, non-alcoholic fatty liver, non-alcoholic steatohepatitis, hepatic ischemia-reperfusion injury, primary biliary cirrhosis, and the like.

Patent application WO 2018133866 discloses pyridine derivatives useful as ASK1 inhibitors, and a preparation method and use thereof, wherein compound WX001, i.e., compound 5- (4-cyclopropyl-1H-imidazol-1-yl) -N- (6- (6, 7-dihydro-5H-pyrrolo [2,1-c ] [1,2,4] triazol-3-yl) pyridin-2-yl) -2-fluoro-4-methylbenzamide (compound represented by formula (I)), is specifically disclosed. Patent application WO2019034096 discloses a fused bicyclic compound and application thereof in medicine, wherein example 2 specifically discloses 5- (4-cyclopropyl-1H-imidazol-1-yl) -N- (6- (6, 7-dihydro-5H-pyrrolo [2,1-c ] [1,2,4] triazol-3-yl) pyridin-2-yl) -2-fluoro-4-methylbenzamide (a compound shown in formula (I)) and a preparation method thereof. However, these patent applications do not disclose the crystal structure of the compound, nor the pharmaceutically acceptable salts thereof.

Drug polymorphism is also a common phenomenon in drug development and is an important factor affecting drug quality. Different crystal forms of the same drug may be significantly different in appearance, solubility, melting point, dissolution rate, bioavailability and the like, and also have different influences on the stability, bioavailability, curative effect and the like of the drug. Therefore, the choice of the salt of the drug and the problem of polymorphism should be considered comprehensively in drug development.

Amorphous forms of a substance can be obtained by a number of methods known in the art. Such methods include, but are not limited to, quenching, anti-solvent flocculation, ball milling, spray drying, freeze drying, wet granulation, and solid dispersion techniques, among others.

"solvent" refers to a substance (typically a liquid) that is capable of completely or partially dissolving another substance (typically a solid). Solvents useful in the practice of the present invention include, but are not limited to, water, acetic acid, acetone, acetonitrile, benzene, chloroform, carbon tetrachloride, methylene chloride, dimethyl sulfoxide, 1, 4-dioxane, ethanol, ethyl acetate, butanol, t-butanol, N-dimethylacetamide, N-dimethylformamide, formamide, formic acid, heptane, hexane, isopropanol, methanol, methyl ethyl ketone, mesitylene, nitromethane, polyethylene glycol, propanol, pyridine, tetrahydrofuran, toluene, xylene, mixtures thereof, and the like.

By "anti-solvent" is meant a fluid that facilitates precipitation of the product (or product precursor) from the solvent. The anti-solvent may comprise a cold gas, or a fluid that promotes precipitation by a chemical reaction, or a fluid that reduces the solubility of the product in the solvent; it may be the same liquid as the solvent but at a different temperature, or it may be a different liquid than the solvent.

"solvate" refers to a compound having a solvent on a surface, in a crystal lattice, or on and in a crystal lattice, which may be water, acetic acid, acetone, acetonitrile, benzene, chloroform, carbon tetrachloride, methylene chloride, dimethyl sulfoxide, 1, 4-dioxane, ethanol, ethyl acetate, butanol, t-butanol, N-dimethylacetamide, N-dimethylformamide, formamide, formic acid, heptane, hexane, isopropanol, methanol, methyl ethyl ketone, methyl pyrrolidone, mesitylene, nitromethane, polyethylene glycol, propanol, pyridine, tetrahydrofuran, toluene, xylene, mixtures thereof, and the like. A specific example of a solvate is a hydrate, wherein the solvent on the surface, in the crystal lattice or on the surface and in the crystal lattice is water. The hydrates may or may not have other solvents than water on the surface of the substance, in the crystal lattice or both.

Crystalline forms or amorphous forms can be identified by a variety of techniques, such as X-ray powder diffraction (XRPD), infrared absorption spectroscopy (IR), melting point methods, Differential Scanning Calorimetry (DSC), thermogravimetric analysis (TGA), nuclear magnetic resonance methods, raman spectroscopy, X-ray single crystal diffraction, dissolution calorimetry, Scanning Electron Microscopy (SEM), quantitative analysis, solubility and dissolution rate, and the like.

Information such as change, crystallinity, crystal structure state and the like of the crystal form can be detected by X-ray powder diffraction (XRPD), and the method is a common means for identifying the crystal form. The peak positions of the XRPD patterns depend primarily on the structure of the crystalline form, being relatively insensitive to experimental details, while their relative peak heights depend on a number of factors related to sample preparation and instrument geometry. Accordingly, in some embodiments, the crystalline form of the present invention is characterized by an XRPD pattern having certain peak positions, substantially as shown in the XRPD patterns provided in the figures of the present invention. Also, the 2 θ measurement of the XRPD pattern may have experimental error, and the 2 θ measurement of the XRPD pattern may be slightly different from instrument to instrument and from sample to sample, so the 2 θ value cannot be considered absolute. The diffraction peaks have a tolerance of ± 0.2 ° according to the conditions of the instrument used in the test.

Differential Scanning Calorimetry (DSC) is performed under programmed control by continuously measuringHeating or cooling, and measuring the sample and inert reference (commonly used alpha-Al)₂O₃) The energy difference therebetween varies with temperature. The endothermic peak height of the DSC curve depends on many factors related to sample preparation and instrument geometry, while the peak position is relatively insensitive to experimental details. Thus, in some embodiments, the crystalline form of the present invention is characterized by a DSC profile with characteristic peak positions substantially as shown in the DSC profiles provided in the figures of the present invention. Meanwhile, the DSC profile may have experimental errors, and the peak position and peak value of the DSC profile may slightly differ between different instruments and different samples, so the peak position or peak value of the DSC endothermic peak cannot be regarded as absolute. The endothermic peaks have a tolerance of ± 3 ° depending on the condition of the instrument used in the test.

Thermogravimetric analysis (TGA) is a technique for measuring the change in mass of a substance with temperature under program control, and is suitable for examining the loss of a solvent in a crystal or the sublimation and decomposition of a sample, and it can be presumed that the crystal contains crystal water or a crystal solvent. The change in mass shown by the TGA profile depends on many factors such as sample preparation and instrumentation; the mass change of the TGA detection varies slightly from instrument to instrument and from sample to sample. The amorphous form described herein is characterized by a weight loss range of 1.75% to 4.10% as measured by TGA. There is a tolerance of + -0.1% for mass change depending on the condition of the instrument used in the test.

In the context of the present invention, the 2 θ values in the X-ray powder diffraction pattern are all in degrees (°).

The term "substantially as shown" means that at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 99% of the peaks in the X-ray powder diffraction pattern or DSC pattern or raman spectrum or infrared spectrum are shown in the figure.

When referring to a spectrogram or/and data appearing in a graph, "peak" refers to a feature that one skilled in the art would recognize as not being attributable to background noise.

The invention relates to various salts of 5- (4-cyclopropyl-1H-imidazol-1-yl) -N- (6- (6, 7-dihydro-5H-pyrrolo [2,1-c ] [1,2,4] triazol-3-yl) pyridin-2-yl) -2-fluoro-4-methylbenzamide (compound shown in formula (I)) and crystal forms thereof, which exist in a basically pure crystal form or an amorphous form.

By "substantially pure" is meant that a crystalline form is substantially free of one or more additional crystalline forms, i.e., 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% pure, or the crystalline form contains additional crystalline forms, the percentage of which in the total volume or weight of the crystalline form is less than 20%, or less than 10%, or less than 5%, or less than 3%, or less than 1%, or less than 0.5%, or less than 0.1%, or less than 0.01%.

By "substantially free" is meant that the percentage of one or more other crystalline forms in the total volume or weight of the crystalline form is less than 20%, or less than 10%, or less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.5%, or less than 0.1%, or less than 0.01%.

"relative intensity" (or "relative peak height") in an XRPD pattern refers to the ratio of the intensity of the first strong peak to the intensity of the other peaks when the intensity of the first strong peak is 100% of all the diffraction peaks in an X-ray powder diffraction pattern (XRPD).

In the context of the present invention, the word "about" or "approximately" when used or whether used, means within 10%, suitably within 5%, and especially within 1% of a given value or range. Alternatively, the term "about" or "approximately" means within an acceptable standard error of the mean, for one of ordinary skill in the art. Whenever a number is disclosed with a value of N, any number within the values of N +/-1%, N +/-2%, N +/-3%, N +/-5%, N +/-7%, N +/-8% or N +/-10% is explicitly disclosed, wherein "+/-" means plus or minus.

"room temperature" in the present invention means a temperature of 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.
