[0002] The present disclosure relates to solid forms and salts of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid (FT011), in amorphous and crystalline form, processes for their preparation, and pharmaceutical compositions thereof. The disclosure also relates to methods of using such solid forms and salts and pharmaceutical compositions thereof for treating, preventing, or ameliorating diseases or conditions associated with fibrosis, inflammation, and / or proliferation. [Background technology]

[0003] Fibrosis is the abnormal accumulation of collagen matrix after injury or inflammation, altering the structure and function of various tissues. Regardless of the location, the primary pathology of fibrosis involves excessive deposition of collagen matrix, replacing normal tissue at that site. Progressive fibrosis in the kidney, liver, lung, heart, bone or bone marrow, and skin is a major cause of death and suffering. Although the etiology and causative mechanisms of individual fibrotic disorders can be diverse (e.g., ischemic events, exposure to chemicals, radiation, or infectious agents) and are poorly understood, they all share the common feature of abnormal and excessive deposition of extracellular matrix in affected tissues (Wynn and Ramalingam, Nat. Med. 2012, 18:1028). Fibrosis contributes to 45 percent (45%) of all deaths worldwide in developed countries, resulting in a significant unmet clinical need.

[0004] Chronic heart failure (CHF) is a growing public health problem in developed countries. It is well recognized that the causes of CHF are multifactorial. The most common risk factors include coronary heart disease (especially previous myocardial infarction), long-term hypertension, diabetes, and idiopathic cardiomyopathy. However, the impending obesity and diabetes epidemic, combined with an aging population and improved survival rates from heart attacks, signals a significant increase in the number of people with HF due to diabetes and related disorders, and the subsequent future economic health burden (Najafi et al., Eur J Heart Fail 2009;11:472).

[0005] Individuals with diabetes are at increased risk for developing CHF. Even in the absence of other comorbidities such as atherosclerosis or hypertension, diabetes alone manifests as a primary myocardial disease called diabetic cardiomyopathy (DCM). Data from the Framingham Heart Study indicate that diabetes increases the risk of developing HF by 4-5 times. In its early stages, diabetic cardiomyopathy in humans is characterized by abnormal diastolic function, along with subtle changes in systolic function, such as reduced longitudinal fiber contractility. Pathologically, DCM is associated with microvascular disease and shares important similarities with diabetic nephropathy. Examination of left ventricular (LV) biopsies from diabetic patients demonstrates that, at the cellular level, DCM is associated with cardiomyocyte hypertrophy, necrosis, apoptosis, fibroblast proliferation, and, importantly, increased deposition of fibrillar collagen in the interstitial regions (fibrosis). Elevated levels of cardiac fibrosis in these patients correlate with cardiac dysfunction, including increased end-diastolic pressure (EDP), end-diastolic pressure-volume relationship (EDPVR), and end-diastolic volume (EDV), as well as reduced ejection fraction (EF). Thus, pathological fibrosis significantly impacts ventricular compliance and leads to impaired diastolic function due to increased myocardial stiffness.

[0006] The pathological fibrosis underlying cardiac remodeling in diabetes is likely mediated by locally active cytokines such as tumor necrosis factor-α (TNF-α), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and transforming growth factor-β (TGF-β).

[0007] Current treatments for CHF (including diabetic HF) include good glycemic control and treatment with beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor blockers, all of which have been shown to reduce overall mortality and improve clinical symptoms. However, despite such therapy, cardiac dysfunction continues to progress in the majority of patients.

[0008] The increasing prevalence of diabetes and the clear suggestion that pathological fibrosis underlies the decline in diastolic function in CHF in diabetes indicate that additional therapies are needed for the treatment of DCM. Current therapies do not directly target the proinflammatory and profibrotic processes occurring in the diabetic heart.

[0009] Chronic kidney disease (CKD) is a leading cause of morbidity, rehospitalization, and premature mortality, affecting 10–11% of the population in both Europe and the United States (Hallan et al., J Am Soc Nephrol. 2006, 17:2275). In a significant proportion of such patients, deterioration of renal function leads to the development of end-stage kidney disease (ESKD), requiring dialysis or transplantation to sustain life. Research conducted approximately 20 years ago emphasized the importance of blood pressure control and blockade of the renin-angiotensin system to attenuate the progression of CKD to end-stage disease. Unfortunately, although considerable progress has been made in understanding renal pathophysiology, there has been little progress in terms of new therapeutic approaches since then.

[0010] Persistent or repeated injury to the kidney, which has limited capacity for regeneration, leads to the deposition of excessive amounts of extracellular matrix in both the glomerulus and tubulointerstitium. These widespread pathological changes, recognized histologically as glomerular sclerosis and tubulointerstitial fibrosis, infiltrate surrounding structures, inevitably leading to capillary rarefaction, resulting in hypoxia, tubular atrophy, and inflammatory cell infiltration. These structural changes subsequently lead to a decline in glomerular filtration rate (GFR), which is often, but not always, accompanied by worsening proteinuria. This final common pathway, which occurs in most forms of chronic kidney disease, continues largely regardless of the primary etiology and develops in seemingly diverse disorders, including metabolic, immunological, and infectious causes.

[0011] Over the past decade, research has consistently demonstrated a key role for the pro-fibrotic growth factor transforming growth factor-β (TGF-β) in renal fibrosis and dysfunction. However, other locally active growth factors are also involved in the fibrogenic process, particularly platelet-derived growth factor (PDGF), a potent inducer of matrix synthesis and proliferation of fibrogenic mesenchymal cells, such as fibroblasts and mesangial cells. Consistent with these actions, increased expression of components of both the TGF-β and PDGF pathways has been demonstrated in kidney tissues from a variety of human and experimental kidney diseases. Consequently, each has become an important therapeutic target in efforts to develop new treatments for chronic kidney disease.

[0012] There continues to be a need for new therapies to ameliorate, treat, and / or prevent diseases or conditions associated with fibrosis, inflammation, and / or proliferation, such as diabetic cardiac fibrosis, chronic kidney disease, or cancer. [Prior art documents] [Non-patent literature]

DETAILED DESCRIPTION OF THE INVENTION

[0071] Generally, the nomenclature used herein and the laboratory procedures in organic chemistry, medicinal chemistry, pharmacology, pharmaceutical science, and medicine described herein are those well known and commonly used in the art. Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art.

[0072] The term "subject" refers to an animal, including, but not limited to, a primate (e.g., a human), cow, pig, sheep, goat, horse, dog, cat, rabbit, rat, or mouse. The terms "subject" and "patient" are used interchangeably herein, e.g., with reference to a mammalian subject, e.g., a human subject, in one embodiment, a human.

[0073] The terms "treat," "treating," and "treatment" are meant to include alleviating or abolishing a disorder, disease, or condition, or one or more symptoms associated with the disorder, disease, or condition, or alleviating or eradicating the cause of the disorder, disease, or condition itself.

[0074] The terms "prevent," "preventing," and "prevention" are meant to include methods of delaying and / or eliminating the onset of a disorder, disease, or condition, and / or its attendant symptoms, preventing a subject from contracting a disorder, disease, or condition, or reducing a subject's risk of contracting a disorder, disease, or condition.

[0075] As used herein, and unless otherwise specified, the terms "manage," "managing," and "management" refer to preventing or slowing the progression, spread, or worsening of a disease, disorder, or condition, or one or more symptoms thereof. Often, the beneficial effects a subject derives from a prophylactic and / or therapeutic agent do not result in a cure of the disease or disorder. In this regard, the term "managing" encompasses treating a subject afflicted with a particular disease to prevent or minimize recurrence of the disease.

[0076] As used herein, amelioration of symptoms of a particular disorder by administration of a particular pharmaceutical composition refers to any relief, whether permanent or temporary, lasting or transient, that can be attributed to or associated with administration of the composition.

[0077] As used herein, the term "disorder" is intended to be generally synonymous with, and is used interchangeably with, the terms "disease," "syndrome," and "condition" (as in medical condition), in that it reflects an abnormal condition of the human or animal body or parts thereof that impairs normal function and is typically manifested by prominent signs and symptoms.

[0078] The term "therapeutically effective amount" is meant to include an amount of a compound that, when administered, is sufficient to prevent the onset of, or alleviate to some extent, one or more of the symptoms of the disorder, disease, or condition being treated. The term "therapeutically effective amount" also refers to an amount of a compound sufficient to elicit the biological or medical response in a biological molecule (e.g., protein, enzyme, RNA, or DNA), cell, tissue, system, animal, or human that is sought by a researcher, veterinarian, medical doctor, or clinician.

[0079] As used herein, and unless otherwise specified, a "prophylactically effective amount" of a compound is an amount sufficient to prevent a disease or disorder or prevent its recurrence. A prophylactically effective amount of a compound refers to an amount of a therapeutic agent that, alone or in combination with one or more other agents, provides a prophylactic benefit in the prevention of a disease. The term "prophylactically effective amount" can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.

[0080] "Fibrotic condition," "fibrotic disease," and "fibrotic disorder" are used interchangeably herein to refer to a condition, disease, or disorder characterized by dysregulated fibroblast proliferation or activity, and / or abnormal accumulation of fibronectin, and / or pathological or excessive accumulation of collagen tissue. Typically, any such disease, disorder, or condition is amenable to treatment by administering a compound with antifibrotic activity. Fibrotic disorders include, but are not limited to, renal fibrosis, skin fibrosis, pancreatic fibrosis, liver fibrosis (e.g., liver fibrosis associated with chronic active hepatitis), and pulmonary fibrosis, including idiopathic pulmonary fibrosis (IPF) and pulmonary fibrosis of known etiology.

[0081] "Cardiac fibrosis" refers to the formation of fibrous tissue, including cellular and extracellular components, in the cardiac endothelium and muscle. When present in sufficient amounts, the fibrous tissue results in decreased contractility and / or relaxation of one or more regions of the heart, resulting in functional deficits in cardiac output.

[0082] "Diabetic cardiomyopathy" refers to any one or more cardiac lesions and / or dysfunctions in a subject that are complications of either type I or type II diabetes. Diabetes may be symptomatic or asymptomatic. Cardiac lesions characteristic of diabetic cardiomyopathy include myocyte hypertrophy, myocardial fibrosis, and in some cases, left ventricular hypertrophy. The lesions considered occur independently of complications resulting from coronary artery disease, but both diabetic complications and coronary artery complications may be present in the same subject. Diastolic dysfunction, such as impaired early diastolic filling, prolonged isovolumic relaxation, and increased atrial filling, is also a characteristic of diabetic cardiomyopathy, and can be identified using Doppler methods such as Doppler two-dimensional echocardiography (e.g., Redford MM et al., "Burden of systolic and diastolic dysfunction in the community", JAMA (2003) 289:194-203) or radionuclide imaging for early or mild dysfunction, and standard echocardiography for more severe dysfunction.

[0083] As used herein, the term "kidney disease" may refer to at least one kidney disorder in a subject that impairs kidney function. Kidney disease can result from a primary kidney lesion (e.g., glomerular or tubular damage) or from another organ (e.g., the pancreas) that adversely affects the kidney's ability to perform biological functions. Kidney disease in humans can be the direct or indirect effect of disease. An example of kidney disease as a result of an indirect effect on the kidney is kidney disease as a result of diabetes or systemic lupus. Kidney disease can be the result of any change, damage, or trauma to the glomeruli, tubules, or interstitial tissue in either the renal cortex or renal medulla of the kidney. As used herein, the term "kidney disease" can refer to a progressive kidney disease that results in loss of kidney function over time (e.g., days, weeks, months, or years).

[0084] Kidney disease may include, but is not limited to, progressive glomerular kidney disease, including, but not limited to, diabetic nephropathy (e.g., as a result of type I or type II diabetes or systemic lupus), primary glomerulonephritis (e.g., membranous nephropathy, focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, diffuse proliferative glomerulonephritis, membranous focal segmental glomerulosclerosis), or secondary glomerulonephritis (e.g., diabetic nephropathy, ischemic nephropathy).

[0085] As used herein, the term "renal function" refers to a physiological characteristic of the kidney, such as its ability to retain protein and thereby prevent proteinuria. Renal function can be assessed using methods known in the art, such as determining one or more of the glomerular filtration rate (e.g., creatinine clearance), urinary protein excretion, blood urea nitrogen, and serum or plasma creatinine.

[0086] Progressive kidney diseases treated by the salts, pharmaceutical compositions, and methods described herein include any kidney disease that can ultimately lead to end-stage renal disease. Progressive kidney diseases that can be treated by the compositions and methods of the invention can be associated, for example, with endogenous iron deposition in the kidney (e.g., glomeruli, tubules).

[0087] The terms "pharmaceutically acceptable carrier," "pharmaceutically acceptable excipient," "physiologically acceptable carrier," or "physiologically acceptable excipient" refer to a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, solvent, or encapsulating material.

The release rate of the active ingredient can also be adjusted by changing the particle size and polymorphism of the active ingredient.

[0297] The controlled-release dosage forms of the pharmaceutical compositions provided herein can be prepared using matrix controlled-release devices known to those skilled in the art (see Takada et al. in "Encyclopedia of Controlled Drug Delivery," Vol. 2, Mathiowitz Ed., Wiley, 1999).

[0298] In certain embodiments, the pharmaceutical compositions provided herein in modified release dosage form are formulated using erodible matrix devices that are water-swellable, erodible, or soluble polymers, including, but not limited to, synthetic polymers and naturally occurring polymers and derivatives such as polysaccharides and proteins.

[0299] Materials useful for forming erodible matrices include chitin, chitosan, dextran, and pullulan; agar gum, gum arabic, gum karaya, locust bean gum, tragacanth gum, carrageenan, ghatti gum, guar gum, xanthan gum, and scleroglucan; starches such as dextrin and maltodextrin; hydrophilic colloids such as pectin; phosphatides such as lecithin; alginates; propylene glycol alginate; gelatin; collagen; ethyl cellulose (EC), methylethyl cellulose (MEC), carboxymethyl cellulose (CMC), CMEC, hydroxyethyl cellulose (HEC), hydroxypropyl ... Cellulose-based materials such as hydroxypropyl cellulose (HPC), cellulose acetate (CA), cellulose propionate (CP), cellulose butyrate (CB), cellulose acetate butyrate (CAB), CAP, CAT, hydroxypropyl methylcellulose (HPMC), HPMCP, HPMCAS, hydroxypropyl methylcellulose acetate trimellitate (HPMCAT), and ethyl hydroxyethyl cellulose (EHEC); polyvinylpyrrolidone; polyvinyl alcohol; polyvinyl acetate; glycerol fatty acid esters; polyacrylamide; polyacrylic acid; copolymers of ethacrylic acid or methacrylic acid (EUDRAGIT®, Rohm Copolymers of L-glutamic acid and ethyl-L-glutamate; degradable lactic acid-glycolic acid copolymers; poly-D-(-)-3-hydroxybutyric acid; and other acrylic acid derivatives such as homopolymers and copolymers of butyl methacrylate, methyl methacrylate, ethyl methacrylate, ethyl acrylate, (2-dimethylaminoethyl) methacrylate, and (trimethylaminoethyl) methacrylate chloride.

[0300] In certain embodiments, the pharmaceutical compositions provided herein are formulated in a non-erodible matrix device. The active ingredient is dissolved or dispersed in an inert matrix and, upon administration, is released primarily by diffusion through the inert matrix. Materials suitable for use as a non-erodible matrix device include polyethylene, polypropylene, polyisoprene, polyisobutylene, polybutadiene, polymethyl methacrylate, polybutyl methacrylate, chlorinated polyethylene, polyvinyl chloride, methyl acrylate-methacrylate copolymer, ethylene-vinyl acetate copolymer, ethylene / propylene copolymer, ethylene / ethyl acrylate copolymer, vinyl acetate, vinylidene chloride, vinyl chloride copolymers with ethylene and propylene, ionomeric polyethylene terephthalate, butyl rubber, and epichlorohydrin rubber. Insoluble plastics such as ethylene / vinyl alcohol copolymers, ethylene / vinyl acetate / vinyl alcohol terpolymers, ethylene / vinyloxyethanol copolymers, polyvinyl chloride, plasticized nylon, plasticized polyethylene terephthalate, natural rubber, silicone rubber, polydimethylsiloxane, and silicone carbonate copolymers; hydrophilic polymers such as ethyl cellulose, cellulose acetate, crospovidone, and cross-linked partially hydrolyzed polyvinyl acetate; and fatty compounds such as carnauba wax, microcrystalline wax, and triglycerides.

[0301] In matrix controlled release systems, the desired release kinetics can be controlled, for example, through the type of polymer used, the polymer viscosity, the particle size of the polymer and / or the active ingredient, the ratio of active ingredient to polymer, and other excipients or carriers in the composition.

[0302] The pharmaceutical compositions provided herein in modified release dosage form can be prepared by methods known to those skilled in the art, including direct compression, dry or wet granulation followed by compression, and melt granulation followed by compression.

[0303] The pharmaceutical compositions provided herein in modified release dosage forms can be manufactured using osmotic controlled release devices, including, but not limited to, one-chamber systems, two-chamber systems, asymmetric membrane technology (AMT), and extruded core systems (ECS). Generally, such devices have at least two components: (a) a core containing an active ingredient, and (b) a semipermeable membrane with at least one delivery port that encapsulates the core. The semipermeable membrane controls the influx of water from an aqueous environment into the core during use, allowing drug release to occur by extrusion through the delivery port.

[0304] In addition to the active ingredient, the core of the osmotic device optionally contains an osmotic agent that generates a driving force for transporting water from the environment of use into the core of the device. One class of osmotic agents are water-swellable hydrophilic polymers, also referred to as "osmopolymers" and "hydrogels." Water-swellable hydrophilic polymers suitable as osmotic agents include, but are not limited to, hydrophilic vinyl and acrylic polymers, polysaccharides such as calcium alginate, polyethylene oxide (PEO), polyethylene glycol (PEG), polypropylene glycol (PPG), poly(2-hydroxyethyl methacrylate), poly(acrylic) acid, poly(methacrylic) acid, polyvinylpyrrolidone (PVP), crosslinked PVP, polyvinyl alcohol (PVA), PVA / PVP copolymers, PVA / PVP copolymers with hydrophobic monomers such as methyl methacrylate and vinyl acetate, hydrophilic polyurethanes containing large PEO blocks, croscarmellose sodium, carrageenan, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropylmethylcellulose (HPMC), carboxymethyl cellulose (CMC) and carboxyethyl cellulose (CEC), sodium alginate, polycarbophil, gelatin, xanthan gum, and sodium starch glycolate.

[0305] Another class of osmotic agents is osmogens, which can absorb water and affect the osmotic pressure gradient across the barrier of the surrounding coating. Suitable osmogens include, but are not limited to, inorganic salts such as magnesium sulfate, magnesium chloride, calcium chloride, sodium chloride, lithium chloride, potassium sulfate, potassium phosphate, sodium carbonate, sodium sulfite, lithium sulfate, potassium chloride, and sodium sulfate; sugars such as dextrose, fructose, glucose, inositol, lactose, maltose, mannitol, raffinose, sorbitol, sucrose, trehalose, and xylitol; organic acids such as ascorbic acid, benzoic acid, fumaric acid, citric acid, maleic acid, sebacic acid, sorbic acid, adipic acid, edetic acid, glutamic acid, p-toluenesulfonic acid, succinic acid, and tartaric acid; urea; and mixtures thereof.

[0306] Osmotic agents with different dissolution rates can be used to affect how rapidly the active ingredient is initially delivered from the dosage form. For example, amorphous sugars such as MANNOGEM™ EZ (SPI Pharma, Lewis, DE) can be used to provide faster delivery in the first few hours to rapidly produce the desired therapeutic effect, with the remaining amount gradually and continuously released to maintain the desired level of therapeutic or prophylactic effect over an extended period of time. In this case, the active ingredient is released at a rate that replaces the amount of active ingredient that is metabolized and excreted.

[0307] The core can also include various other excipients and carriers as described herein to improve the performance of the dosage form or to facilitate stability or processing.

[0308] Materials useful for forming semipermeable membranes include various grades of acrylics, vinyls, ethers, polyamides, polyesters, and cellulose derivatives that are water-permeable and water-insoluble at physiologically relevant pH or that are susceptible to being made water-insoluble by chemical alteration, such as crosslinking. Examples of suitable polymers useful for forming coatings include plasticized, unplasticized, and reinforced cellulose acetate (CA), cellulose diacetate, cellulose triacetate, CA propionate, cellulose nitrate, cellulose acetate butyrate (CAB), CA ethyl carbamate, CAP, CA methyl carbamate, CA succinate, cellulose acetate trimellitate (CAT), CA dimethylaminoacetate, CA ethyl carbonate, CA chloroacetate, CA ethyl oxalate, CA methyl sulfonate, CA butyl sulfonate, CA p-toluene sulfonate, agar acetate, amylose triacetate, beta-glucan acetate, beta-glucan acetate, and the like. triacetate, acetaldehyde dimethyl acetate, triacetate of locust bean gum, hydroxylated ethylene vinyl acetate, EC, PEG, PPG, PEG / PPG copolymers, PVP, HEC, HPC, CMC, CMEC, HPMC, HPMCP, HPMCAS, HPMCAT, poly(acrylic) acids and esters and poly(methacrylic) acids and esters and copolymers thereof, starch, dextran, dextrin, chitosan, collagen, gelatin, polyalkenes, polyethers, polysulfones, polyethersulfones, polystyrene, polyvinyl halides, polyvinyl esters and ethers, natural waxes, and synthetic waxes.

[0309] The semipermeable membrane may also be a hydrophobic microporous membrane, in which the pores are substantially gas-filled and not wetted by aqueous media but are permeable to water vapor, as disclosed in U.S. Patent No. 5,798,119. Such hydrophobic but water vapor permeable membranes are typically composed of hydrophobic polymers such as polyalkenes, polyethylene, polypropylene, polytetrafluoroethylene, polyacrylic acid derivatives, polyethers, polysulfones, polyethersulfones, polystyrene, polyvinyl halides, polyvinylidene fluoride, polyvinyl esters and ethers, natural waxes, and synthetic waxes.

[0310] Delivery ports in the semipermeable membrane can be formed after coating by mechanical or laser drilling. Delivery ports can also be formed in situ by erosion of a plug of water-soluble material or by rupture of a thinner portion of the membrane over a depression in the core. In addition, delivery ports can be formed during the coating process, as in the case of asymmetric membrane coatings of the type disclosed in U.S. Patent Nos. 5,612,059 and 5,698,220.

[0311] The total amount and rate of release of the active ingredient can be substantially controlled by the thickness and porosity of the semipermeable membrane, the composition of the core, and the number, size, and location of the delivery ports.

[0312] The osmotic controlled-release dosage form of the pharmaceutical composition may further comprise additional conventional excipients or carriers as described herein to facilitate performance or processing of the formulation.

[0313] The pharmaceutical compositions provided herein in modified-release dosage forms can be manufactured as multiparticulate controlled-release devices comprising a multiplicity of particles, granules, or pellets ranging in diameter from about 10 μm to about 3 mm, from about 50 μm to about 2.5 mm, or from about 100 μm to about 1 mm. Such multiparticulates can be made by processes known to those skilled in the art, including wet and dry granulation, extrusion / spheronization, roller compaction, melt congealing, and spray coating of seed cores. See, e.g., Multiparticulate Oral Drug Delivery; Marcel Dekker: 1994, and Pharmaceutical Pelletization Technology; Marcel Dekker: 1989.

[0314] Other excipients or carriers as described herein can be blended with the pharmaceutical composition to aid in the processing and formation of the multiparticulates. The resulting particles can themselves constitute the multiparticulate device or can be coated with various film-forming materials, such as enteric polymers, water-swellable, and water-soluble polymers. The multiparticulates can be further processed as capsules or tablets.

[0315] The pharmaceutical compositions provided herein can also be formulated to target specific tissues, receptors, or other areas of the body of the subject being treated, such as liposome-, resealed red blood cell-, and antibody-based delivery systems.

[0485] The present disclosure is further illustrated by the following examples, which are not intended to limit the scope of the claims.

[0486] Example 1. General Experiment Reagents and materials All inorganic reagents, organic solvents, and water are of at least analytical laboratory reagent grade standard. device [Table 3]

[0487] Instrument parameters X-ray powder diffraction (XRPD) X-ray powder diffraction (XRPD) patterns were obtained on a Shimadzu XRD-6000 instrument. XRPD bulk patterns were measured at room temperature. Samples were measured by XRPD using the following method: [Table 4]

[0488] Differential scanning calorimetry (DSC) Approximately 1 mg of sample was tested in a pinhole aluminum pan under nitrogen purge using a ramp rate of 20°C / min over the range of 30°C to 300°C (the test range was adjusted according to the decomposition temperature of the sample). [Table 5]

[0489] Thermogravimetric analysis (TGA) A sample of the compound (4-6 mg) was weighed into a pan and heated under a nitrogen purge using a ramp rate of 20°C / min over the range 30°C to 350°C, then held at 350°C for an additional 1 min. [Table 6]

[0490] Dynamic Vapor Sorption (DVS) Approximately 10 mg of sample was used to test the moisture sorption / desorption profile at 25°C during a 0% to 95% to 0% relative humidity (RH) cycle with the following parameters: [Table 7]

[0491] During DVS analysis, humidity is held at each value during a 0%-95%-0% RH cycle and changed in 5% RH increments, measuring the change in mass at each such value. For example, a sample is exposed to an increase in relative humidity from 25% RH to 30% RH, and the resulting mass change is measured. Humidity is held constant at 30% RH until the sample's mass equilibrium is reached, as determined by a weight change rate of 0.01% / min or less. The humidity is then changed to the next step value, the resulting mass change is measured, and so on. Thus, while moisture response profiles are observed over a range of conditions during a 0%-95%-0% RH cycle, a standard comparison can be provided by moisture content values ​​at a set condition, such as 80% RH. Table 11 lists the hygroscopicity values ​​of relevant samples during the sorption cycle by listing the moisture content at mass equilibrium measured at 80% RH during the ramp-up from 0 to 95% RH.

[0492] Thus, when hygroscopicity values ​​are reported herein at a particular humidity, they refer to values ​​obtained at the stated humidity level measured during a sorption cycle that increased humidity from 0% RH to 95% RH before returning to 0% RH. The hygroscopicity values ​​reported herein refer only to the total moisture gain since the start of the experiment and, therefore, do not necessarily equate to the actual total moisture content of the sample.

[0493] The hygroscopicity of the samples was classified as follows: [Table 8]

[0494] Polarized Light Microscope (PLM) Samples dispersed in silicone oil were observed using an eyepiece (10x) and an objective lens (40x) under crossed polarizers and recorded by a camera / computer system with a magnification scale.

[0495] 1 H nuclear magnetic resonance (NMR) Approximately 3 mg of sample was weighed into a nuclear magnetic tube, and 0.5 mL of deuterated dimethyl sulfoxide or deuterated methanol was added to completely dissolve the sample.

[0496] Solubility measurement Approximately 8-12 mg of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid salt (equimolar to 8 mg of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid free form) was accurately weighed into each glass vial, followed by the addition of 4 ml of the indicated medium. The samples were stirred at 37 °C using a magnetic stirrer. After stirring for 1 or 24 hours, 1 ml of each sample was withdrawn and the final pH recorded. The samples were filtered by centrifugation (12,000 rpm, 5 min). The supernatant was diluted (2x) with HPLC-grade solvent and analyzed by HPLC.

[0497] The HPLC conditions were as follows: Column: Agilent Eclipse Plus C18, 150 × 4.6 mm, 3.5 μm, Column temperature: 35 °C, Flow rate: 1.0 mL / min, Detector wavelength: 230 nm, Run time: 12 min, Injection volume: 5 μL, Diluent: Acetone, Mobile phase A (MPA): 0.1% TFA in HO, Mobile phase B (MPB): ACN.

[0498] The HPLC gradient was as follows: [Table 9]

[0499] Example 2. Preparation of salts of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid Approximately 100 mg of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid ("FT011 free form," hereinafter also referred to as "API") was accurately weighed into each glass vial. An appropriate amount of solvent selected from ethyl acetate (EA) and 90% isopropanol (90% IPA) was then added to the glass vial, and the mixture was heated to 50°C. A counterion source selected from potassium hydroxide, meglumine, ethanolamine (MEA), tris(hydroxymethyl)aminomethane (Tris base), tert-butylamine (TBA), ammonia, lysine, L-arginine, and choline was added to each vial in an appropriate molar ratio (e.g., 5% molar excess). In the case of meglumine and Tris base, they were accurately weighed and mixed with FTO11 free form, and then the solvent was added to the mixture. Each mixture was stirred at 50°C for 1 hour, then cooled to room temperature (20-25°C) and continued stirring for 24-48 hours, after which the solid precipitate was isolated by centrifugation. If no precipitate was present in the system, the clear solution was evaporated at room temperature by compressed air or nitrogen blowing. The obtained sample was dried overnight under vacuum at 40°C. The dried sample was 1 The salts were analyzed by H NMR, TGA, DSC, and PLM. The detailed procedure for the formation of the salts and their physical properties are summarized in Table 1. [Table 10-1] [Table 10-2] [Table 10-3]

[0500] Based on the experimental results, potassium hydroxide, meglumine, ethanolamine (MEA), tris(hydroxymethyl)aminomethane (Tris base), tert-butylamine (TBA), ammonia, and lysine formed crystalline solid salt forms with (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid. Sodium hydroxide formed a less crystalline solid salt form, whereas L-arginine and choline did not form solid salt forms but instead formed oils.

[0501] The ethanolamine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid was obtained as a crystalline solid and analyzed by X-ray powder diffraction (XRPD) and single crystal X-ray diffraction (SXRD). The X-ray powder diffraction pattern of a sample of crystalline Form I of the ethanolamine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid prepared as described above is shown in FIG. 1 and shows prominent XRP diffraction peaks at 6.6, 11.7, 15.9, 17.7, 23.7, and 26.6 degrees two-theta (±0.2 degrees two-theta). As used herein, "prominent peaks" are a subset of the entire observed peak list. Prominent peaks are selected from the observed peaks, preferably by identifying non-overlapping peaks with strong intensities. The observed XRP diffraction peaks are listed in Table 2a. Table 2b lists the prominent peaks calculated from SXRD. SXRD measurements of the monohydrate MEA salt were performed at -103°C (170K), while the XRPD bulk pattern was measured at room temperature. This temperature difference results in shrinkage of the crystalline form (at lower temperatures); therefore, slight changes in the crystalline structure and resulting peak positions are observed compared to those at room temperature. The overall patterns of SXRD and XRPD are consistent in terms of diffraction peaks and relative peak heights and are therefore comparable, except for the noted effect of temperature on the precise 2-theta values. Table 2c shows the calculated SXRD peaks for crystalline Form I of the ethanolamine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid. The variability in the values ​​is explained by the standard experimental error in measuring the relevant parameters, as understood by those skilled in the art. For example, in Table 2c, "a" (Å) is listed as 4.7710±(8), which means that values ​​from 4.7702 to 4.7718 are explicitly included; "b" (Å) is listed as 29.645±(4), which means that values ​​from 29.641 to 29.649 are explicitly included; and so on.This approach applies to all such SXRD values ​​described in the same or similar manner herein.

[0502] The tert-butylamine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid was obtained as a crystalline solid and analyzed by X-ray powder diffraction (XRPD). The X-ray powder diffraction pattern of a sample of crystalline Form II of the tert-butylamine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid prepared as described above is shown in Figure 8 and shows prominent XRP diffraction peaks at 8.36, 13.96, and 17.50 degrees two-theta (±0.2 degrees two-theta). The observed XRP diffraction peaks are listed in Table 3. [Table 14]

[0503] The meglumine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid was obtained as a crystalline solid and analyzed by X-ray powder diffraction (XRPD). The X-ray powder diffraction pattern of a sample of crystalline Form III of the meglumine salt of (E)-2-[[3-(3-methoxy-4-propargyloxy)phenyl)-1-oxo-2-propenyl]amino]benzoic acid prepared as described above is shown in Figure 9 and shows prominent XRP diffraction peaks at 7.50, 12.86, 15.26, and 23.92 degrees two-theta (±0.2 degrees two-theta). The observed XRP diffraction peaks are listed in Ta...
