Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical engineering crystallization technology, and more specifically, to a crystal form, its preparation method, and its application. Background Technology
[0002] Compound 2-[(all-E)3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetradecenyl]-5,6-dimethoxy-3-methyl-p-benzoquinone (Coenzyme Q10) is a vitamin-like compound, a fat-soluble organic quinone compound widely distributed in organisms, and has important physiological and pharmacological effects. It is primarily a coenzyme bound to the mitochondrial membrane, forming a link in the respiratory chain, and participates in hydrogen transfer during energy metabolism in the body. It is a metabolic activator that activates cellular respiration, generates cellular energy, and accelerates the production of adenosine triphosphate (ATP). It is also a natural antioxidant produced by the cell itself, inhibiting mitochondrial peroxidation and protecting the integrity of biological membrane structures. Simultaneously, it is a non-vitamin nutrient that, after consumption, activates cellular respiration, accelerates the production of high-energy ATP, strengthens myocardial metabolism, improves heart rate, regulates cellular and tissue hypoxia, and has good protective and improving effects on the liver, brain, heart, and nervous system. It also has a very specific immune-enhancing effect, increasing the phagocytic rate of phagocytes and increasing antibody production. Due to these excellent properties, Coenzyme Q10 has become an important pharmaceutical and health supplement with broad application prospects.
[0003] Coenzyme Q10 comes in two forms: oxidized and reduced. Currently, most coenzyme Q10 products on the market are oxidized. Oxidized coenzyme Q10, also known as decenquinone or ubiquinone, is chemically named 2-[(all-E)3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetradecenyl]-5,6-dimethoxy-3-methyl-p-benzoquinone. It is a lipid-soluble quinone compound with a structure similar to vitamin K, vitamin E, and plastoquinone. It is a yellow or light yellow crystalline powder, readily soluble in chloroform, benzene, and carbon tetrachloride; soluble in acetone and ether; slightly soluble in ethanol; and insoluble in water and methanol. Oxidized coenzyme Q10 (structure shown below) suffers from poor photostability and easily decomposes into a red substance upon exposure to light. The photostability of oxidized coenzyme Q10 greatly limits its applications. Current solutions to this problem include either protecting it from light during production and storage, or preparing it into coated tablets, capsules, or other formulations to improve its stability.
[0004]
[0005] For example, Chinese patent application CN119385957A discloses a tablet with high bioavailability and its preparation method; Chinese patent application CN101744288A discloses a clarified oral formulation containing coenzyme Q10 and its preparation method; Chinese patent application CN101053556A discloses a scheme for encapsulating coenzyme Q10 with hydroxypropyl-β-cyclodextrin as cyclodextrin, followed by drying to prepare a coenzyme Q10 inclusion complex; Chinese patent application CN109953967A discloses a process study of coenzyme Q10 tablets, the technical solution of which uses a film coating as an enteric film coating premix for coenzyme Q10, which can obtain coenzyme Q10 tablets with high release. The above technical solutions involve formulating coenzyme Q10 into a formulation form, but none of these technical solutions have investigated the photostability of the formulation.
[0006] The phenomenon that a compound can exist in at least one crystalline structure or solid form is called polymorphism. Many compounds can exist in multiple crystalline forms, as well as in amorphous solid forms. Before discovering polymorphism in a compound, it is difficult to predict: (1) whether a particular compound exhibits polymorphism; (2) how to prepare these unknown polymorphs; and (3) what the properties of these polymorphs will be, such as stability. Since the properties of any solid depend on its structure and the properties of the compound itself, different solid forms of a compound can and often exhibit different physical and chemical properties. Differences in chemical properties can be measured, analyzed, and compared using various analytical techniques. These differences can ultimately be used to distinguish between different solid forms. Many existing patents disclose methods for preparing coenzyme Q10 crystal forms. However, the methods for preparing oxidized coenzyme Q10 disclosed in the prior art all yield existing crystal forms. For example, the main characteristic peaks of oxidized coenzyme Q10, expressed as 2θ values ± 0.2°, appear at 11.3, 18.5, 20.2, 22.7, and 23.3, as described in "Design of Coenzyme Q10 solid dispersion for improved solubilization and stability" (Jin-Seok, et al. International journal of pharmaceutics 572(2019):118832-118832.).
[0007] However, this crystal form A does not solve the problem of poor photostability of coenzyme Q10. Therefore, investigating whether there are new crystal structures for coenzyme Q10 is of great significance to overcome its insufficient photostability. Summary of the Invention
[0008] The purpose of this invention is to provide: A crystal form of compound 2-[(all-E)3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetradecenyl]-5,6-dimethoxy-3-methyl-p-benzoquinone, its preparation method and application, and related technologies, to solve technical problems such as providing a new crystal form with significantly improved stability, especially overcoming the defect of poor photostability, or a combination thereof.

Unless otherwise stated, all patents, patent inventions, and publications cited in this document are incorporated herein by reference in their entirety. If multiple definitions exist for terms in this document, the definitions in this chapter shall prevail.
[0010] It should be understood that the above brief description and the following detailed description are exemplary and for illustrative purposes only, and do not limit the subject matter of the invention in any way. In this invention, the singular is used in conjunction with the plural unless otherwise specifically stated.

[0012] The definition of standard chemical terms can be found in the reference "Basic Organic Chemistry (Volumes 1 & 2)" by Xing Qiyi, Higher Education Press, 3rd Edition, 2005-06.
[0013] Unless otherwise stated, conventional methods within the scope of the art, such as mixing, filtering, stirring, dropping, centrifugation, crystallization, crystal growth, rinsing, and drying, shall be used.
[0014] Unless specifically defined herein, the use of all commercially available products herein employs standard techniques. For example, it may be carried out using the manufacturer's instructions for use with the kit, or in accordance with methods known in the art or the description of this invention. The techniques and methods described herein can generally be implemented according to conventional methods well known in the art, based on the descriptions in the various summary and more specific documents cited and discussed in this specification.
[0015] The terms “optional / arbitrary” or “optionally / arbitrarily” mean that the event or situation described below may or may not occur, including both the occurrence and non-occurrence of the event or situation.
[0016] The term "mixing" as used in this article refers to the process of reducing the heterogeneity of two or more substances (such as solid powders, liquids, or solid-liquid mixtures) and achieving a uniform combination through the action of external forces (such as stirring, convection, or shearing).
[0017] The term "filtration" as used in this article refers to the core operation in organic chemistry for separating solid-liquid mixtures. It involves using a porous medium to trap solid particles, allowing the liquid to pass through, thus achieving separation. Specifically, it is the physical process of using a filter medium (such as filter paper) to trap solid particles in a suspension, allowing the liquid to pass through; relying on gravity, pressure, or centrifugal force to drive the liquid through the pores of the medium, while the solids are trapped to form a filter cake.
[0018] The term "stirring" as used in this article refers to the process of thoroughly mixing reactants by mechanical or magnetic means, which is especially crucial in heterogeneous reactions (such as solid-liquid and liquid-liquid reactions). It accelerates the contact of reactants, promotes uniform heat distribution, and avoids localized overheating that could lead to side reactions.
[0019] The term "drop addition" as used in this article refers to the gradual addition of reactants dropwise using a device such as a constant-pressure funnel, primarily for controlling reaction rate and temperature. For example, in strongly exothermic reactions, drop addition can prevent violent reactions; in reactions involving reactive substances, drop addition can maintain stable reactant concentrations.
[0020] As used in this article, "centrifugation" refers to the technique of separating components of different densities in a mixture using the centrifugal force generated by a centrifuge. In organic chemistry, it is often used to separate precipitates from solutions or to remove small particles from reaction systems.
[0021] The term "crystallization" as used in this article refers to the process by which a solute in a solution precipitates out of a supersaturated state to form crystals. By controlling conditions such as temperature and stirring speed, crystal products with high purity can be obtained.
[0022] The term "crystal growth" as used in this article refers to maintaining specific conditions (such as temperature and stirring) for a period of time after crystallization to allow the crystals to grow more completely and with higher purity. This process can reduce impurity inclusions and improve product quality.
[0023] As used in this article, "rinsing" refers to the process of washing a solid surface with a solvent to remove residual impurities. For example, after crystallization, rinsing the crystal with a low-boiling-point solvent can facilitate subsequent drying.
[0024] As used in this article, "drying" refers to the process of removing moisture or other solvents from a compound by heating, vacuuming, or using a desiccant.
[0025] As used herein, the term "pharmaceutically acceptable carrier" refers to a pharmaceutically acceptable material, such as liquid or solid fillers, stabilizers, dispersants, suspending agents, diluents, excipients, thickeners, solvents, or encapsulating materials, relating to the carrying or transport of any pharmaceutical composition from one organ or part of the body to another organ or part of the body. Each carrier must be "acceptable" in the sense of compatibility with other components of the pharmaceutical composition and harmlessness to the patient.
[0026] The term “X-ray powder diffraction” as used in this article refers to an analytical technique used to analyze and identify the crystal structure of polycrystalline or powdered materials. Its theoretical basis is that when a beam of monochromatic X-rays is irradiated onto countless randomly oriented tiny crystals, interference diffraction occurs, producing a diffraction pattern with a specific design.
[0027] The term "2θ angle" as used in this paper refers to twice the angle between the incident X-ray direction and the diffracted X-ray direction in the geometry of an X-ray diffraction experiment. It is the abscissa of the XRD pattern and is the angle directly measured in the experiment.
[0028] The term "crystal form" as used in this article refers to a solid form with a microstructure that has a long-range ordered arrangement, generally referring to a solid form with a microstructure that has a long-range ordered arrangement in three-dimensional space.
[0029] The term "diffraction peak" as used in this article refers to a peak in powder X-ray diffraction (XRD) analysis that has a significantly higher intensity than the background signal on a diffraction pattern (a curve showing the intensity as a function of the diffraction angle 2θ). Each diffraction peak corresponds to the coherent diffraction of incident X-rays by a specific set of crystal planes (hkl) in the crystalline sample. The position of the diffraction peak (peak position, usually expressed as a 2θ angle) and the interplanar spacing (d-value) follow Bragg's law, reflecting the lattice structure parameters of the crystal. The intensity of the diffraction peak (peak height or integrated intensity) is related to factors such as the type, number, and arrangement of atoms on the diffracting crystal plane, as well as the content of that phase in the sample. The width of the diffraction peak (e.g., half-maximum width at half maximum) is related to the crystal's grain size, microstrain, and other structural characteristics.
[0030] As used in this article, the term "characteristic diffraction peak" or "characteristic peak" refers to a set of highly specific and reproducible diffraction peaks exhibited by a specific crystalline phase (such as a specific crystal form of a drug) in its powder X-ray diffraction pattern. The positions (2θ values) of these diffraction peaks and their relative intensities constitute the "fingerprint" pattern of that phase, which can be used to distinguish it from other phases or crystal forms.
[0031] The term "Cu-Kα radiation" used in this article refers to Cu-Kα radiation, also known as Cu Kα rays, which is a characteristic X-ray source commonly used in X-ray diffraction analysis. Its generation principle is as follows: when a high-energy electron beam bombards a copper (Cu) target, it ionizes the inner-shell (K-shell) electrons of the copper atoms, creating vacancies. Subsequently, outer-shell (L-shell) electrons jump to these K-shell vacancies, releasing X-ray photons with specific energies—this is Cu Kα radiation. It mainly consists of two spectral lines with very close wavelengths: Kα1 (wavelength approximately 1.54056 Å) and Kα2 (wavelength approximately 1.54439 Å). In conventional diffraction analysis, their weighted average wavelength is often taken as approximately 1.5418 Å. Due to its fixed wavelength, relatively good monochromaticity, and high intensity, Cu-Kα radiation is widely used in laboratory X-ray diffractometers as a standard incident light source for the structural analysis of crystal materials.

[0326] Basic Example 1: Synthesis of oxidized coenzyme Q10 as a starting material: 28.0 g of decaisoprene alcohol (purchased from Yichang Zhongyitai Trading Co., Ltd.) was dissolved in 400 mL of a petroleum ether:diethyl ether (1:1) mixture with stirring. 7.6 g of 2,3-dimethoxy-5-methyl-hydroquinone (purchased from Keanlong (Tianjin) Industrial Co., Ltd.) was added and stirred until dissolved. Then, 4.4 g of anhydrous zinc chloride and 0.32 mL of glacial acetic acid were added. The mixture was stirred under nitrogen protection for 3 h. Nitrogen gas was then stopped, and 72 g of 30% ferric chloride solution was added. The mixture was stirred at room temperature for 1 h. The organic phase was collected after standing and separating into layers. It was washed with 5 wt% brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain an orange-red oily substance. Ethanol was added to give a yellow solid. The 1H NMR spectrum is attached. Figure 1The compound identified as 2-[(all-E)3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetradecenyl]-5,6-dimethoxy-3-methyl-p-benzoquinone was selected as the starting material for subsequent experiments.
[0327] Example 1 1.1 Preparation (1) Preparation - Batch 1 2.5 g of the compound obtained in Basic Example 1 was added to a beaker containing 50 mL of petroleum ether as a starting material and stirred until dissolved, yielding a 50 mg / mL petroleum ether solution of the compound. This solution was rapidly added to an ethanol solution containing PVP K30 (where the mass fraction of PVP K30 was 0.3%, and the volume ratio of ethanol to petroleum ether solution was 6:1), and mixed and stirred under controlled temperature conditions in a propylene glycol-ethanol (coolant) bath (stirring rate 4000 r / min, stirring time 10 min), continuously precipitating crystals to form a pale yellow suspension. The suspension was filtered through a Buchner funnel and washed with ethanol to remove residual petroleum ether and surfactant. The collected wet powder was frozen at -40°C for 2 h, and then freeze-dried under vacuum (vacuum pressure 10-50 Pa, freezing temperature -45°C to 50°C) to obtain a yellow dry particulate solid.
[0328] The obtained solid was subjected to crystal form XRPD diffraction analysis using the method described in the embodiments of this application. The diffraction angle (2θ) of the obtained solid crystal exhibited diffraction peaks at 11.3±0.2°, 11.7±0.2°, 14.1±0.2°, 18.7±0.2°, 20.2±0.2°, 22.5±0.2°, 22.8±0.2°, and 23.3±0.2°. Comparison with the characteristic peaks of crystal forms disclosed in the prior art confirms that it is a known crystal form, defined as crystal form A.
[0329] (2) Preparation - Batch 2 In a 100mL three-necked flask, add 60mL of anhydrous ethanol and 15mL of isobutanol. While stirring, add 5g of the compound obtained in Basic Example 1 as the starting material. Heat to 55-60℃ to dissolve, filter, pour the filtrate into a 100mL three-necked flask, stir and cool, crystallize, grow crystals, centrifuge, wash with a small amount of anhydrous ethanol, and dry at 35-40℃ to obtain a yellow crystalline solid.
[0330] (3) Preparation - Batch 3 In a 100 mL three-necked flask, 50 mL of cyclohexane and 25 mL of isopropyl acetate were added. 3 g of the compound prepared in Basic Example 1 was added as the starting material while stirring. The mixture was heated to 50 °C to dissolve, filtered, and the filtrate was transferred to a 100 mL three-necked flask. The mixture was concentrated under reduced pressure and dried at 35-40 °C to obtain a yellow crystalline solid.
[0331] 1.2 Product stability test The stability test method for all batches of products prepared above was as follows: approximately 5 mg of sample was weighed and placed in a vial, and stability studies were conducted under high humidity (25ºC / 60% RH) and light (25ºC / 4500 Lux) conditions, respectively. HPLC tests were performed on samples taken at 0 days and 30 days.
[0332] The results are shown in Table 1 below: Table 1
[0333] As shown in Table 1, through stability tests of different batches of products, the inventors found that there were significant differences in the stability of different batches of products under light conditions. The product obtained in batch 3 showed significantly better light stability than other batches, while the products obtained in other batches had poor light stability and the amount of impurities increased far beyond the standard of less than 1% for total impurities stipulated in the pharmacopoeia.
[0334] 1.3 Identification of the crystal form of this invention: Based on the aforementioned differences in performance, further research and characterization were conducted on the product obtained in batch 3. It was found that the crystal form of the product obtained in batch 3 differed from other batches and known crystal forms, as shown in its XRPD diffraction pattern. Figure 2 As shown.
[0335] It has been confirmed that the main characteristic diffraction peaks in the above-mentioned diffraction peaks include 4.70, 6.25, 15.65, 17.22, 19.18, 20.45, and 27.39. The characteristic diffraction peaks of this crystal form are significantly different from those of the known crystal form A, indicating a new crystal form, which is named the crystal form of this invention. Figure 2 The XRPD diffraction pattern of the crystal form of this invention is shown.
[0336] The DSC results of the crystal form of this invention show that an endothermic peak appears at 49.67℃; the TGA results show that its weight loss is only 0.37% before 100℃; the above data indicate that the crystal form of this invention is an amorphous form.
[0337] The DVS evaluation results of the crystal form of this invention are as follows: Figure 3 As shown, the results indicate that the crystal form of the present invention has a moisture absorption weight gain of 0.07% at 25℃ / 80% humidity, which, according to the Chinese Pharmacopoeia, is considered to be non-hygroscopic or almost non-hygroscopic, and the crystal form remains unchanged before and after DVS.
[0338] 1.4 Determination of the bulk density of the crystal form of the present invention: The bulk density was measured according to the first method disclosed in the Chinese Pharmacopoeia (2020 edition). Specifically, one accurately graduated sample vial was weighed using a balance with a weight of 0.01%. The crystal form of the present invention was allowed to fall freely into the vial until the top of the solid was level with the 1 mL mark. The top was then gently scraped flat with a spatula. The total loose weight of each sample was accurately weighed, and the bulk density of the crystal form of the present invention was calculated to be 0.45 g / mL.
[0339] Example 2 Crystal sieve test When the inventors discovered that there were significant differences in the stability of different batches of products, and that the crystal form obtained through crystal form characterization was different from the known crystal form in the prior art, they conducted crystal sieve tests on the crystal form system in order to obtain crystal forms with further differences in properties.
[0340] 2.1 Recrystallization by Antisolvent Addition Method Weigh approximately 20 mg of sample into a 5 mL glass vial. Simultaneously, pre-cool the corresponding antisolvent at 5°C. Dissolve the sample in the corresponding normal solvent at room temperature (using methods such as sonication, shaking, and heating, using the minimum amount of solvent possible to ensure a higher solution concentration), and filter through a 0.45 μm nylon filter. Reserve the filtrate. Then, stir the normal solvent filtrate while slowly adding the antisolvent dropwise to induce crystallization. Once a solid forms, immediately stop stirring and characterize with XRPD. If the sample is clear, place it at 5°C and continue stirring; if it remains clear, transfer it to -20°C and continue stirring until a solid forms for characterization.

A certain amount of solvent was added to dissolve the sample, resulting in a saturated, clear solution. This solution was then filtered through a 0.45 μm nylon filter. The filtrate was collected in another glass bottle, which was then sealed with aluminum foil with 3-5 small holes punched in it to ensure slow evaporation of the solvent in the environment. The solid was collected for XRPD characterization. Each vial was wrapped with aluminum foil during the experiment to prevent photodegradation. The results of the solvent evaporation crystallization method are shown in Table 3 below.

The temperature in the crystallizer was maintained at 303.15 K, and the mixture was stirred at 200 r / min until completely dissolved, resulting in an initial concentration of 18%. Ethanol (the volume ratio of the positive solvent tetrahydrofuran to the antisolvent ethanol was 1:7) was added dropwise to the solution at 2.0 mL / min, along with 2% seed crystals. The temperature was lowered to 282.15 K at 0.5 K / min, and the mixture was crystallized and matured for 90 min. The mixture was filtered, the filter cake was washed with ethanol, and then air-dried at room temperature. The resulting solid was characterized by XRPD using the method described in this application. The diffraction angles (2θ) of the obtained solid crystal showed diffraction peaks at 11.3±0.2°, 11.7±0.2°, 14.1±0.2°, 18.7±0.2°, 20.2±0.2°, 22.5±0.2°, 22.8±0.2°, and 23.3±0.2°. By comparing the characteristic peaks with those of the crystal forms disclosed in the prior art, its known crystal form is defined as crystal form A.
[0341] Example 3 Impurity changes in crystal form A and the crystal form of this invention were tested under illumination (natural light, light box) conditions. The HPLC detection method is as described in the embodiments of this application. The results are shown in Tables 5 and 5 (continued). Figures 4-9 As shown: Table 5
[0342] Table 5 (continued)
[0343] Note: ND indicates not detected.
[0344] As can be seen from Tables 5 and 5 (continued), under illumination conditions (including natural light and an illuminated chamber), the content of crystal form A decreases significantly with increasing time. The content of some known impurities (such as impurities with RRT=0.81) increases significantly, even exceeding the single impurity limit (0.5%). Some unknown impurities (such as impurities with RRT=0.57) begin to form, and their content even exceeds the single impurity limit (0.5%). In contrast, under illumination conditions, the content of the crystal form of this invention remains basically stable with increasing time, with virtually no change or almost no impurity formation.
[0345] Therefore, crystal form A must be strictly protected from light during production and storage, and special treatment measures or packaging must be taken to prevent the compound from being affected by light, which increases production and storage costs. Moreover, crystal form A will develop photochemical degradation product impurities (including unknown impurities with RRT=0.096, RRT=0.24, RRT=0.25, RRT=0.57, and RRT=0.63) over time during storage.
[0346] Furthermore, according to the Chinese Pharmacopoeia (2020 Edition, Part II), the content of a single impurity must not exceed 0.5%, and the total impurities must not exceed 1.0%. If crystal form A is not subjected to strict light-protection measures during production and storage, the impurity content (including single and total impurities) will increase significantly, exceeding the Chinese Pharmacopoeia standard. This necessitates repeated crystallization, preventing its direct use in the formulation process; recrystallization is required before it can be used in the next stage of formulation production. In contrast, the crystal form of this invention has no special requirements for production and storage conditions, saving production and storage costs and reducing the possibility of photochemical degradation products appearing over time during storage.
[0347] Application Example 1 Crystal form A and the crystal form of the present invention are prepared into formulations according to the formulations in Table 6 below.

KG), microcrystalline cellulose (commercially available, purchased from Japan Asahi Kasei Corporation), and calcium carboxymethyl cellulose (commercially available, purchased from Bolak Co., Ltd.), and then mix each raw material with purified water for 4 minutes to obtain a mixed powder; (2) Wet granulation: The mixed powder is granulated using a wet granulator. The granulator blade speed is 900 rpm and the stirring speed is 300 rpm. Water is added for granulation, and the process is run for 60 seconds. Then, a second granulation is performed with the granulator blade speed at 1500 rpm and the stirring speed at 300 rpm for 30 seconds. (3) Drying and granulation: The particles obtained by wet granulation are dried by fluidized bed drying, and then colloidal silica (commercially available, purchased from Evonik Operations GmbH) is granulated together with the dry particles; (4) Premixing: Add the granulated material, microcrystalline cellulose (commercially available, purchased from Asahi Kasei Corporation, Japan) and calcium carboxymethyl cellulose (commercially available, purchased from Bolak Co., Ltd.) to the mixer hopper for premixing; (5) Final mixing: Add magnesium stearate (commercially available, purchased from Huzhou Zhanwang Pharmaceutical Co., Ltd.) to the premixed material and perform final mixing; (6) Tableting: The final mixed material is added to a double-outlet high-speed tablet press and tableted to obtain the tablets (Formulation 1 uses the crystal form of the present invention as raw material, and Formulation 2 uses crystal form A as raw material), with a specification of 100mg / tablet and a total of 500 tablets.
[0349] Application Test Case 1 Stability tests of the formulation under high temperature, high humidity, and light exposure: To further investigate the effects of different crystal forms on the impurities and content of the formulation, stability tests were conducted on formulation 1 containing the crystal form of the present invention and formulation 2 containing crystal form A, as follows: Weigh 5 mg of the sample and place it into a vial. Stability studies were conducted under high temperature (40ºC), high humidity (92.5% RH), and light conditions. HPLC tests were performed at 0, 14, or 30 days.
[0350] The stability results of the formulation are shown in Table 7 below: Table 7
[0351] As shown in Table 7, under 30 days of high temperature and high humidity conditions, the total impurities in Formulation 2 containing crystal form A increased significantly, with a slight decrease at high temperature and a relatively constant content under high humidity conditions. Under 14 days of light exposure conditions, the total impurities in Formulation 2 increased, while the content decreased significantly. In contrast, under 30 days of high temperature and high humidity conditions, the total impurities in Formulation 1 containing the crystal form of this invention remained essentially unchanged, while the content remained essentially constant. Under 14 days of light exposure conditions, the total impurities in Formulation 1 changed slightly, while the content remained essentially constant. Therefore, Formulation 1 exhibits better stability than Formulation 2 under the same conditions, making it easier to store and transport, thus saving on storage and transportation costs.
[0352] Application Test Example 2 Dissolution stability test of formulation: The stability test method for formulation 1 containing the crystal form of the present invention and formulation 2 containing crystal form A, prepared in the above application test example 1, was as follows: 5 mg of sample was weighed and placed in a vial, and stability studies were conducted under high temperature (40ºC) and high humidity (92.5% RH) conditions. Samples were taken at 0 days (same as parameter control), 10 days, and 30 days to test the dissolution of the formulations. Dissolution conditions: Agilent, slurry method, 900 mL, 50 rpm, 5% Triton (octylphenol polyoxyethylene ether, density 1.07 g / mL, pH 6.0-8.0). The results are shown in Table 8 below: Table 8
[0353] As shown in Table 8, under high-temperature testing conditions, the dissolution of formulation 2 containing crystal form A showed significant changes before 1 hour, reaching a dissolution plateau after 1 hour. Dissolution accelerated significantly by day 10, and increased slightly by day 30 compared to day 10. Under high-humidity testing conditions, the dissolution of formulation 2 remained essentially unchanged by day 0 after day 10, but there was virtually no dissolution before day 15 by day 30, and dissolution slowed significantly after day 15. In contrast, formulation 1 containing the crystal form of this invention showed essentially unchanged dissolution by day 0 under both high-temperature and high-humidity testing conditions, whether at day 10 or day 30. Therefore, the dissolution stability of formulation 1 containing the crystal form of this invention is significantly higher than that of formulation 2 containing crystal form A, making it easier to store and transport, better ensuring the consistency of (therapeutic) effects, and reducing fluctuations in efficacy or adverse reactions caused by dissolution differences.
