Description

[Technical Field]

[0001] This application relates to the biopharmaceutical field, and specifically to salts of compounds and their crystalline forms, methods of preparation and uses. [Background technology]

[0002] Rifamycins are natural products with potential antimicrobial activity. Naturally derived rifamycins (e.g., rifamycin B, rifamycin O, rifamycin R, rifamycin U, rifamycin S, rifamycin SV, and rifamycin Y (Brufani, M., Cerrini, S., Fedeli, W., Vaciago, AJ Mol. Biol. 1974, 87, 409-435)) have limited therapeutic applications, including relatively poor pharmacokinetics, low oral bioavailability, weak activity against gram-negative pathogens, and low distribution in infected tissues. In the prior art, various semisynthetic rifamycin derivatives with improved antibacterial spectra and pharmacological properties have been produced by chemical modification. Among these semisynthetic compounds, for example, rifampin and rifabutin have already been developed as therapeutic agents and are currently used to treat tuberculosis and other microbial infections (Farr, B.M. Rifamycins, in Principles and Practice of Infectious Diseases, Mandell, G.L., Bennett, J.E., Dolin, R., Eds., Churchill, 11 Livingstone, Philadelphia, pp. 348-361). Also, for example, TNP-2198 is a dual-targeted rifamycin-nitroimidazole conjugate that has potent activity against microaerophilic and anaerobic bacterial pathogens and good activity against strains resistant to both rifamycins and nitroimidazoles. However, in the development and application process, such innovative drug molecules with antibacterial activity often have difficulty meeting the demand for drug discoverability as a pharmaceutical due to the influence of their physicochemical properties such as high relative molecular mass in the free form, high lipophilicity, low water solubility and hygroscopicity, as well as bioavailability and stability (chemical stability, thermal stability, melting point, crystalline form stability). In this field, research on new drugs of rifamycin derivatives, such as crystalline forms of rifabutin (e.g., CN103408571B), has also progressed in recent years, but the experiments provided in this application reveal that they still face the problem of low purity and difficulty in meeting the demand for drug discoverability.Therefore, the search and screening of new molecular entities (eg, salt forms or crystalline forms) of such original drug molecules plays a vital role in realizing their medicinal value.

[0072] Without intending to be limited by any theory, the following examples are merely illustrative of the triphenylacetate salts of the compounds of the present application, methods of preparation, and uses thereof, and are not intended to limit the scope of the present invention. [Example]

[0073] Example 1 Preparation of monotriphenylacetate salts of exemplary compounds (1) Characterization of the starting sample of the example compound The exemplary compound has the structure shown in Formula (II) (hereinafter referred to as TNP-2198), and the starting free-state sample was characterized as amorphous (Figure 1A). As can be seen from the TGA / mDSC results (Figure 1B), the sample had a weight loss of 1.8% before 200°C and a glass transition temperature of 147.8°C. 1 H NMR results (DMSO-d6, Figure 1C) were consistent with the provided target. [ka] At the same time, the solubility of the starting free base of the exemplary compound represented by formula (II) was roughly tested in five single solvents and nine mixed solvents at room temperature (up to 25°C), and the results are shown in Table 1.

[0074] [Table 1] Notes for Table 1: --: No data collected.

[0075] (2) Preparation and Characterization of Salt Forms of Exemplary Compounds 35 mg of crude free base (92.64% purity) was weighed into an HPLC vial. Weigh the acid ligand in the molar ratio corresponding to the table into an HPLC vial (first add a solvent to dilute the liquid acid, then add the free base), add the corresponding solvent, magnetically stir at room temperature for a while, add the corresponding antisolvent in the table, and if necessary, add a small amount of the corresponding seed crystals. After stirring overnight, the sample was centrifuged (10,000 rpm, 2 mins) and then vacuum dried at room temperature (25° C.) for 4 hours. The solid was collected and characterized, and the results are shown in Table 2.

[0076] [Table 2] Notes for Table 2: The yield was roughly calculated according to the screening system and may not represent the final process system. --: No data collected.

[0077] Example 2 Comparative stability experiment of monotriphenylacetate salts of example compounds (1) The monotriphenylacetate sample of the exemplary compound represented by formula (II) and the comparative examples (the hydrochloride and phosphate salts of the exemplary compound) were dried under vacuum at room temperature (up to 25°C) for 5 hours and then characterized by HPLC. The results are shown in Table 3. [Table 3] Notes for Table 3: The yield was roughly calculated according to the screening system and may not represent the final process system. --: Purity / yield is relatively low, and no further data on acid-base molar ratios have been collected; As can be seen from the salt formation results in Table 3, in the salt formation process of the compound of Formula II with different acids, the phosphate and hydrochloride salts result in a decrease in the purity of the compound and the production of decomposition impurities, whereas the monotriphenylacetate salt not only has better crystallinity but also significantly improves the purity of the compound, thereby achieving the purpose of separation and purification.

[0078] (2) Stability experiment Two types of crystalline forms I and II of the monotriphenylacetate salt of the exemplary compound represented by formula (II) were sampled and left under open conditions of 25°C / 60%RH and 40°C / 75%RH for 3 days. The results are shown in Table 4. As can be seen from the results in Table 4, under the two stability test conditions, the monotriphenylacetate sample showed no significant changes in properties or purity. Combining the results in Tables 3 and 4, compared with the hydrochloride and phosphate, the monotriphenylacetate has a moderate degree of crystallinity, and the crystalline form did not change under the two conditions, proving that the monotriphenylacetate of the example compound has good performance in both crystallinity and stability.

[0079] [Table 4]

[0080] Example 3 Preparation of Crystal Forms I to IV of the Present Application (1) Preparation of Crystal Form I To 10 mL of ethyl acetate (EtOAc), 1.00 g of TNP-2198 compound was added, and a solution of triphenylacetic acid in ethyl acetate (0.30 g + 2 mL of EtOAc) was slowly added dropwise. The mixture was stirred at 20-30°C for 18-20 hours to precipitate a solid. 3 mL of ethyl acetate solution was added to the reaction mixture, and after filtration, the wet cake was washed with 2.5 mL of solvent. The wet cake was dried under vacuum at 20-30°C for 4 hours or more, finally yielding 0.83 g of crystalline powder with a yield of 63.35% and an HPLC purity of 99.94%. A sample was then sampled for XRPD, TGA, and DSC testing. The results are shown in Figure 2, Table 5, and Figures 3A-3B.

[0081] Characterization results of crystalline form I: The diffraction peaks in XRPD showed that crystalline form I had a very high degree of crystallinity. 1 The stoichiometry was determined to be 1.0 (acid / base molar ratio) by H NMR (DMSO-d6), and no solvent residue was observed. TGA results indicated a weight loss of 0.7% (~0.5% H2O) before heating to 180°C. DSC results indicated that 166.5°C was the starting temperature for weight loss. At the same time, Form I showed no morphological change after heating to 120°C, and the heat-treated sample showed negligible weight loss before decomposition (Figures 10A-10B). After heating to 180°C, the melting of Form I samples could be observed. From the above data, Form I is likely to be monotriphenylacetic anhydride.

[0082] Further purification method 1 of crystalline form I: Add 1.8 g of TNP-2198 triphenylacetate crystalline form I (purity 95.1%) to a reaction flask, add 18 mL (10 volumes) of 2-butanone, heat to 50°C, stir and clarify, cool to 25°C, add 18 mg (1%) of seed crystals of TNP-2198 triphenylacetate crystalline form I, stir at this temperature for 1 hour, then slowly add 36 mL (20 volumes) of n-heptane, cool to 0°C and stir at this temperature for 11 hours. The resulting mixture was filtered to obtain 1.45 g of wet product, which was then added to a reaction flask, followed by the addition of 18 mL (10 volumes) of 2-butanone, and the temperature was raised to 50°C and stirred to clarify. After cooling to 25°C, 18 mg (1%) of TNP-2198 triphenylacetate Form I seed crystals were added and stirred at this temperature for 2 hours. After that, 36 mL (20 volumes) of n-heptane was added dropwise, the temperature was gradually lowered to 0°C and stirred at this temperature for 14 hours. After filtering and drying, 1.35 g of product was obtained, with a purity of 99.7%.

[0083] Further purification method 2 of crystalline form I: Add 1.8 g of TNP-2198 triphenylacetate crystalline form I (purity 95.1%) to a reaction flask, add 18 mL (10 volumes) of acetone, heat to 50°C, stir and clarify, cool to 25°C, add 18 mg (1%) of seed crystals of TNP-2198 triphenylacetate crystalline form I, stir at this temperature for 1 hour, slowly add 36 mL (20 volumes) of n-heptane, cool to 0°C and stir at this temperature for 11 hours. The resulting mixture was filtered to obtain 1.45 g of wet product, which was then added to a reaction flask, and 18 mL (10 volumes) of acetone was added. The temperature was raised to 50°C and stirred to clarify. After cooling to 25°C, 18 mg (1%) of TNP-2198 triphenylacetate Form I seed crystals were added and stirred at this temperature for 2 hours. Then, 36 mL (20 volumes) of n-heptane was added dropwise, the temperature was gradually lowered to 0°C and stirred at this temperature for 14 hours. After filtering and drying, 1.29 g of product was obtained, with a purity of 99.0%.

[0084] [Table 5]

[0085] (2) Preparation of Crystal Forms II and III To 13 mL of methyl tert-butyl ether (MTBE) solution, 1.00 g of TNP-2198 compound was added, and a solution of triphenylacetic acid in MTBE (0.30 g + 2 mL of MTBE) was slowly added dropwise. The mixture was stirred at 20-30 °C for 18-20 hours to precipitate a solid. After filtration, the wet cake was washed with 3 mL of solvent. Finally, 0.83 g of crystalline Form II powder was obtained, with a yield of 63.35% and an HPLC purity of 99.28%. A sample was then subjected to XRPD, TGA, and DSC tests. The results of Form II are shown in Figure 4, Table 6, and Figures 5A-5B. Form III was obtained by reactive crystallization of the dried crystalline Form II in a mixed solvent of 2-methyltetrahydrofuran and n-heptane, followed by vacuum drying at 40 °C overnight. The results are shown in Figure 6, Table 7, and Figures 7A-7B.

[0086] Characterization results for crystalline form II: 1 The stoichiometry was determined to be 1.1 (acid / base molar ratio) by H NMR (DMSO-d6), and the MTBE solvent content was determined to be 0.5 (approximately 3.6%) (solvent / API). TGA results showed a weight loss of 2.7% between room temperature and 130°C, followed by a weight loss of 4.0% (MTBE + HO) between 130°C and 185°C. DSC results showed endothermic peaks at 61.9°C, 146.8°C, and 184.6°C. At the same time, Form II showed no morphological changes after heating to 100°C, and after heating to 120°C, the stoichiometry was 0.5 (approximately 3.6%). 1 H NMR (DMSO-d6) showed that the MTBE / API stoichiometry was still 0.2 (approximately 1.7%).

[0087] Characterization results for crystalline form III: 1The stoichiometry was determined to be 0.8 (acid / base molar ratio) by H NMR (DMSO-d6). The solvent content was monitored to determine that the 2-MeTHF / API stoichiometry was 0.2 (approximately 0.9%) and the n-heptane / API stoichiometry was 0.4 (approximately 2.9%). TGA results showed that the weight loss was 5.7% (solvent + HO) before heating to 180°C. DSC results showed endothermic peaks at 64.7°C, 142.8°C, 159.4°C, and 177.0°C. All the above data make it clear that crystalline Forms II and III are likely hydrates or solvates of triphenylacetate.

[0088] [Table 6]

[0089] [Table 7]

[0090] (3) Preparation of Crystalline Form IV The crystalline form obtained in (2) was heated to 160°C and then cooled to room temperature (about 25°C) under N2 purging to obtain crystalline form IV of triphenylacetate, which has a relatively low degree of crystallinity. 1 The stoichiometry was determined to be 1.1 (acid / base molar ratio) by H NMR (DMSO-d6), and the residual amount of MTBE solvent was assumed to be negligible. A sample was then subjected to XRPD, TGA, and DSC tests, with the results shown in Figure 8, Table 8, and Figures 9A-9B. By TGA / DSC, the sample exhibited a 2.0% weight loss (~1.5 H2O) before 180°C and an endothermic peak at 182.8°C. From the above data, it is clear that crystalline Form IV may be a hydrate or an anhydrous form of triphenylacetate.

[0091] [Table 8]

[0092] Example 4 Crystal Form I evaluation experiment (1) Hygroscopicity experiment (Dynamic Vapor Sorption Experiment or DVS) DVS results for Form I (Figure 12A) showed a gradual weight increase from 0 to 60% RH and from 70 to 95% RH, with a rapid weight increase between 60% and 70% RH. A water absorption rate of 1.5% (~1 HO) was observed at 25°C / 80% RH (relative to 0% RH), indicating that Form I is slightly hygroscopic. XRPD results (Figure 12B) showed no change in the morphology of the form before and after DVS evaluation.

[0093] (2) Kinetic solubility Approximately 10 mg / mL of sample (calculated as free radicals) was added to each biological medium. After shaking at 100 rpm at 37°C, samples 01 to 05 (1, 4, and 24 hours) were centrifuged, and the solids were collected and used for XRPD testing, while the supernatants were used for detection and pH measurement. After 24 hours, it can be observed that the solubility of crystalline Form I in FaSSGF (~1.6 mg / mL) was higher than that in the other four media, and no morphological changes were observed in any of the media (in Figure 13, the peak at 31.6° belongs to the NaCl solvent).

[0094] [Table 9] Notes to Table 9: Biomedium: FaSSGF (artificial gastric juice in fasting state) / FeSSGF (artificial gastric juice in fed state) / FaSSIF (artificial intestinal fluid in fasting state) / FeSSIF (artificial intestinal fluid in fed state) S: solubility calculated as free radical (mg / mL); FC: morphological changes; LOQ=0.099 μg / mL.

[0095] Example 5 Preparation of the drug of crystalline form I of the present application Preparation of Crystalline Form I: A crude TNP-2198 ethyl acetate solution (purity 92%, 72 kg) was concentrated and dehydrated by jacket distillation. Triphenylacetic acid (22.4 kg, total 1 eq) was added in several portions and stirred at 25°C for 3 hours. The temperature was then lowered to 5°C and stirring was continued for 2 hours. The mixture was then filtered to obtain Crystalline Form I of TNP-2198 triphenylacetate. Preparation of drug: The wet material obtained in the above process is added to a reactor, and 385.2 kg of 2-butanone is added. The temperature is raised to above 45°C and stirred to clarify. The temperature is lowered to 20-30°C, and 72 g of seed crystals of TNP-2198 triphenylacetate crystalline form I is added. After stirring at 25°C for 2 hours, 655.3 kg of n-heptane is added dropwise. The temperature is slowly lowered to 5°C and stirred for 2 hours. After filtering, the wet material is dried at 40°C to obtain 66.23 kg of product (purity 98.7%). The obtained product can be repeatedly recrystallized in 2-butanone / n-heptane system to obtain TNP-2198 triphenylacetate crystalline form I with a purity of above 99.0%. Crystalline Form I of TNP-2198 triphenylacetate (51.5 kg) obtained in the previous step was dissolved in 1582 kg of dichloromethane at 20-30°C, and 956 kg of 1% diluted Na2CO3 solution was added to wash the dissolved salt. The solvent was replaced with ethyl acetate (less than 10% dichloromethane) by jacket distillation, and the above solution was added dropwise to 1434 kg of n-heptane to precipitate. After filtration and drying at 45°C, free amorphous TNP-2198 (37.2 kg, purity 99.7%) was obtained.

[0096] Example 6 Preparation and Characterization of Forms V and VI of the Present Application 100.04 mg of the compound of formula (I-II) (hereinafter referred to as rifabutin, purity 96.7%) was added to 1.5 mL of ethyl acetate (EtOAc) solution and stirred until completely dissolved. 34.01 mg of triphenylacetic acid was added and stirred at 20-30 °C for 18 hours. 1.5 mL of n-heptane was added to the reaction system, the mixture was filtered, the wet cake was washed with 2 mL of n-heptane, and the wet cake was vacuum dried at 20-30 °C for 8-16 hours to finally obtain 65.11 mg of crystalline form V product with an HPLC purity of 99.5%. 100.01 mg of the same rifabutin was added to 1.5 mL of methyl tert-butyl ether (MTBE) solution and stirred until completely dissolved. 34.03 mg of triphenylacetic acid was added and stirred at 20-30°C for 18 hours. The mixture obtained above was filtered, and the wet cake was washed with 2 mL of MTBE. The wet cake was vacuum dried at 20-30°C for 8-16 hours to finally obtain 54.81 mg of crystalline Form VI product with an HPLC purity of 99.3%. Crystalline Form V and Crystalline Form VI were sampled and subjected to XRPD, TGA and DSC tests, the results of which for Crystalline Form V are shown in Figure 14, Table 10 and Figures 15A-15B, the results of which for Crystalline Form VI are shown in Figure 16, Table 11 and Figures 17A-17B, and a comparison with commercially available amorphous rifabutin product is shown in Figure 18. It can be observed that both Crystalline Form V and Crystalline Form VI are basically identical, with Crystalline Form V having better crystallinity.

[0097] [Table 10]

[0098] [Table 11]

[0099] Example 7 Stability studies of the present crystalline forms V and VI An accelerated experiment was performed on a commercially available amorphous rifabutin product, and crystalline forms V and VI of the present invention, each placed in a constant temperature and humidity chamber at 40°C and 75% humidity, and the change in purity was measured after one month. The results showed that the purity of the amorphous rifabutin product decreased from 95.9% of the original sample to 95.54%, the purity of crystalline form V decreased from 99.34% of the original sample to 99.07%, and the purity of crystalline form VI decreased from 99.1% to 98.87%. This indicates that crystalline forms V and VI of the present invention have the same or higher stability than the commercially available amorphous product.

[0100] Example 8 Crystal purification ability study of the present crystalline form V In this example, amorphous rifabutin crude product was used as the starting material to investigate the crystallization systems of rifabutin triphenylacetate (tetrahydrofuran / n-heptane, butanone / n-heptane, ethyl acetate / n-heptane solvents), and the crystalline rifabutin in Examples 1 and 2 of Patent CN103408571B was used as a control to obtain the purity and yield. The results are shown in Table 12. (1) Comparison of crystalline rifabutin: No. 2: 0.50 g of amorphous rifabutin was added to 35 mL of n-hexane with stirring, and the mixture was heated under reflux and stirred for 30 minutes. The heating was stopped, and the temperature was lowered to 0°C at a rate of 10°C / hour. The mixture was filtered to obtain 0.40 g of crystalline rifabutin, with a purity of 95.46%. Compared with the starting material (No. 1), the purification effect was almost the same. No. 3: 0.50 g of amorphous rifabutin was added to 10 mL of a mixed solvent of n-hexane and ethyl acetate in a volume ratio of 19:1 while stirring, and the mixture was heated under reflux and stirred for 30 minutes. The heating was stopped, and the temperature was lowered to 0°C at a rate of 10°C / hour. The mixture was filtered to obtain 0.22 g of crystalline rifabutin, with a purity of 95.98%. Compared with the starting purity, the purification effect was almost insignificant.

[0101] (2) Crystalline Form V and Crystalline Form VI of the present application: Preparation of crystalline form V (number 4): 7.89g of amorphous rifabutin was added to 40mL of ethyl acetate and stirred to clarify, then 2.68g of triphenylacetic acid and 40mL of n-heptane were added in turn, and the mixture was stirred at room temperature for 4 hours, filtered, and the wet substance was vacuum dried to a constant weight to obtain 7.75g of crystalline form V of rifabutin triphenylacetate, with a purity of 99.3%. Preparation of crystalline form V (No. 5): 8.01 g of amorphous rifabutin was added to 80 mL of methyl tert-butyl ether and stirred to clarify, 2.70 g of triphenylacetic acid was added, and the mixture was stirred at room temperature for 4 hours, filtered, and the wet mass was vacuum dried to a constant weight to obtain 7.10 g of crystalline form VI of rifabutin triphenylacetate, with a purity of 99.2%. As can be seen from the above results, compared with the purification of crystals in Examples 1 and 2 of Patent CN103408571B, crystalline form V significantly improves the purity of the original crude rifabutin under the premise of high yield, and such a purification effect cannot be achieved by the crystalline forms of rifabutin disclosed in the prior art.
