The full texts of the above Chinese patent applications are incorporated into this application by reference.

[0002] This invention relates to the crystalline form, salt form, preparation method, pharmaceutical composition, and use of a five-membered condensed six-membered compound. [Background technology]

[0003] FMS-like tyrosine kinase 3 (FLT3) is a type III receptor tyrosine kinase, and mutations in it are one of the most common genetic alterations and poor prognostic factors in patients with acute myeloid leukemia (AML). The main types of FLT3 mutations are internal tandem duplication mutations in the near-membrane domain (FLT3-ITD) and point mutations or deletions in the tyrosine kinase domain (FLT3-TKD), which account for approximately 30% of AML patients (Kiyoi H, Kawashima N, Ishikawa Y. FLT3 mutations in acute myeloid leukemia: Therapeutic paradigm beyond inhibitor development. Cancer Sci. 2020 Feb;111(2):312-322). Activated FLT3 causes abnormalities in multiple intracellular signaling pathways (RAS, PI3K, STAT5, etc.), leading to hematopoietic cell survival, proliferation, differentiation, and anti-apoptosis. Furthermore, the ratio of mutant to wild-type alleles, insertion site, ITD length, karyotype, and presence of NPM1 gene mutations may influence the prognostic role of FLT3-ITD in newly diagnosed FLT3-ITD mutant AML patients (Daver N, Schlenk RF, Russell NH, Levis MJ. Targeting FLT3 mutations in AML: review of current knowledge and evidence. Leukemia. 2019 Feb;33(2):299-312. Doi: 10.1038 / s41375-018-0357-9.). Because high-dose chemotherapy and allogeneic hematopoietic stem cell transplantation do not adequately improve prognosis, and patients have short survival times and are prone to relapse, FLT3 kinase inhibitors have become a focus of research in AML treatment. First-generation FLT3 inhibitors, such as letaurtinib, sunitinib, sorafenib, ponatinib, and midostaurin, are broad-spectrum inhibitors that can inhibit multiple kinases. However, their efficacy is insufficient, and when used in combination with chemotherapy drugs, they do not show clear efficacy and significantly increase toxicity.For example, while midostaurin alone is insufficiently effective, its combination with cytarabine, daunorubicin, or cytarabine (FDA approved) can be used to treat adult FLT3-mutated AML. Second-generation FLT3 kinase inhibitors such as gilteritinib, crenolanib, and quizartinib offer higher selectivity, stronger activity, and lower toxicity, but still have some off-target effects.

[0004] Currently, three FLT3 inhibitors (quizartinib, gilteritinib, and midostaurin) are approved for sale in Japan and / or the United States as monotherapy or in combination with conventional chemotherapy agents for the treatment of AML patients. These inhibitors have shown good therapeutic responses in clinical practice and have improved the prognosis of AML patients to some extent. When used as monotherapy, the disease relapses rapidly, and both target-dependent and non-target-dependent resistance has already developed. Target-dependent mutations are commonly found in the activation loop (e.g., aspartate 835, D835) and gating residues (e.g., phenylalanine 691, F691), with the D835 mutation being the most common site of targeted resistance mutation. Activation of related signaling pathways can compensate for the inhibition of the FLT3 signaling pathway. Currently, some researchers are working to reduce the rate of non-targeted drug resistance by directly inhibiting related signaling pathways (such as PI3K / AKT and RAS / MEK / MAPK) or by inhibiting signaling pathways related to cell survival through drug combination therapy, but the effects remain limited (Rabik CA, Wang J, Pratilas CA. FLT3-IRAK dual targeting: an exciting new therapeutic option guided by adaptive activation of immune response pathways. Ann Transl Med. 2020 Apr;8(7):511.). After administration of quizartinib and gilteritinib for a certain period, pFLT3 and pSTAT5 expression decreased, but no significant inhibition of tumor cells was observed. In relapsed cases, elevated levels of IRAK4 phosphorylation were observed in a large number of cases, and when combined with IRAK4 inhibitors, tumor cell survival rates were again reduced, suggesting that IRAK4 can be used as a non-targeted drug resistance target.

[0005] Interleukin-1 receptor-related kinases (IRAKs) are serine / threonine protein kinases belonging to the tyrosine-like kinase (TLK) family, with IRAK1 and IRAK4 exhibiting kinase activity. IRAKs are located downstream of the Toll-like receptor and the IL-1R pathway and play a crucial role in innate immune signaling. TLR stimulation recruits MYD88, activating the receptor complex, which then forms a complex with IRAK4 to activate IRAK1. Subsequently, TRAF6 is activated by IRAK1, leading to NF-κB activation. Abnormal activation of the IRAK pathway in tumor cells may further accelerate disease progression through inflammatory responses in the tumor microenvironment (Gummadi VR, Boruah A, Ainan BR, Vare BR, Manda S, Gondle HP, Kumar SN, Mukherjee S, Gore ST, Krishnamurthy NR, Marappan S, Nayak SS, Nellore K, Balasubramanian WR, Bhumireddy A, Giri S, Gopinath S, Samiulla DS, Daginakatte G, Basavaraju A, Chelur S, Eswarappa R, Belliappa C, Subramanya HS, Booher RN, Ramachandra M, Samajdar S. Discovery of CA-4948, an Orally Bioavailable IRAK4 Inhibitor for Treatment of Hematologic Malignancies. ACS Med Chem Lett. 2020 Oct.) (14;11(12):2374-2381.) The development of dual-target compounds that target FLT3 / IRAK4 has potential clinical value and is expected to improve patient prognosis and reduce the likelihood of drug resistance development.

[0373] (Example 4: Preparation of crystalline form)

[0374] 4.1 Preparation of crystal form A 1 g of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed into a reaction vessel. 5 V DMSO / IPA (volume ratio 2:1, where V represents 1 mL of solvent per 1 g of solute) was added, and the mixture was heated to 65°C while stirring to obtain a clear solution. The mixture was then cooled to 50°C and stirred for 0.5 hours. At 50°C, 18.3 V IPA was added and the mixture was reacted for 3 hours. The mixture was then cooled to 20°C at a rate of 10°C / hour and stirred overnight (approximately 16 hours) at 20°C to obtain a solid. The filtered cake was washed with 2 V IPA and dried under vacuum at 50°C to obtain crystalline form A of the free base.

[0375] 4.2 Preparation of crystal form B 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of methanol was added, and the mixture was suspended at room temperature for 3 days. After filtration, solid crystalline form B was obtained.

[0376] 4.3 Preparation of crystal form C 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of acetone / water = 95 / 5 (volume ratio) was added, and the mixture was suspended at room temperature for 3 days. After filtration, solid crystalline form C was obtained.

[0377] 4.4 Preparation of crystal form D 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of methanol was added, and the mixture was suspended at room temperature for 3 days. After filtering to obtain a saturated solution, it was slowly evaporated at room temperature to obtain solid crystalline form D.

[0378] 4.5 Preparation of crystal form E 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of ethanol was added, and the mixture was suspended at room temperature for 3 days. After filtering to obtain a saturated solution, it was slowly evaporated at room temperature to obtain solid crystalline form E.

[0379] 4.6 Preparation of crystal form F 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of acetone-water 95 / 5 (volume ratio) was added, the mixture was suspended at room temperature for 3 days, filtered to obtain a saturated solution, and then slowly evaporated at room temperature to obtain solid crystalline form F.

[0380] 4.7 Preparation of crystal form G 30 mg of the 5-membered condensed 6-membered compound represented by formula I, prepared in Example 1, was weighed out, 0.6 mL of methanol was added, and the mixture was dissolved at 70°C until clear. The mixture was then cooled to 5°C at a rate of 5°C / hour, and the suspension was filtered to obtain the solid crystalline form G.

[0381] (Example 5: Simulated granulation test)

[0382] Dry method: Crystal form A of the 5-membered condensed 6-membered compound represented by formula I was directly pulverized for 30 minutes.

[0383] Wet method: Ethanol, a granulation solvent, was dropped onto the surface of the crystalline form A of the 5-membered condensed 6-membered compound represented by formula I until the solid was completely wet, and then pulverized for 30 minutes. The resulting solid was evaluated using XRPD and DSC to characterize its crystalline form and crystallinity. The purpose was to determine whether polymorphs, solvates, or amorphous compounds were likely to form. As can be seen from the results of the simulated granulation experiment, the crystalline form remained unchanged from crystalline form A, and no new crystalline forms were observed.

[0384] (Example 6: High-voltage characteristics test)

[0385] Approximately 10 mg of crystalline form A of the 5-membered condensed 6-membered compound represented by formula I was weighed out and placed on a 13 mm diameter hydraulic press plate. A high-pressure properties test was then performed using a manual hydraulic press with a hydraulic pressure of 10 tons and a pressing time of 5 minutes. The resulting solid was subjected to property evaluation such as XRPD to observe the stability of the crystalline form under high pressure. As can be seen from the results of the high-pressure treatment experiment, the crystalline form remained unchanged from crystalline form A, and no new crystalline forms were observed.

[0386] (Example 7: Research on crystal transformation relationships)

[0387] To study the interconversion relationships between polymorphs, polymorphs were prepared under repeated conditions, and a series of suspension competition experiments were conducted in different solvent systems for crystalline forms A, C, D, E, and G. The specific experimental steps are as follows.

[0388] 20 mg each of crystal forms A, C, D, E, and G were weighed out and placed in 5 mL glass vials. A suspension was prepared by adding a solvent (EtOH / H2O = 1 / 1 (v / v) or DMSO (dimethyl sulfoxide) / EtOH = 1 / 8 (v / v)). The vials were then transferred to 25°C and stirred for 72 hours. After filtration at different times, the XRPD of the filtered cakes was measured.

[0389] EtOH / H2O1 / 1 solvent system

[0390] [Table 54]

[0391] As can be seen from the suspension experiment using the EtOH / H2O 1 / 1 solvent system, after 24 hours of suspension, the solid sample is in crystalline form C.

[0392] DMSO / EtOH 1 / 8 solvent system

[0393] [Table 55]

[0394] As can be seen from the suspension experiment using the DMSO / EtOH 1 / 8 solvent system, after 24 hours of suspension, the solid sample is in crystalline form A.

[0395] (Example 8: Analysis of polymorphic products)

[0396] Products obtained through polymorphism screening were subjected to tests such as powder X-ray diffraction (XRPD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and high-performance liquid chromatography (HPLC). The newly emerging crystalline forms were summarized, and the relevant spectral diagrams can be found in Figures 1-14.

[0397] [Table 56]

[0398] As can be seen from the summary of the experimental results, of the seven crystal forms discovered, crystal form A has a high melting point and low loss in weight.

[0399] (Example 9: Solid Stability Study - Testing of Influencing Factors)

[0400] To investigate the solid stability of crystal form A, changes in crystal form, purity, and color were examined under various conditions.

[0401] 60 mg of crystal form A was weighed out and placed in a glass dish or vial. This glass dish or vial was then placed in a constant temperature and humidity chamber under the following conditions: light irradiation: 4500 ± 500 Lux, high temperature: 60°C (sealed), high humidity: 25°C, relative humidity RH = 90 ± 5% (open). The results of the study on the solid stability of crystal form A are shown in the table below.

[0402] [Table 57]

[0403] As can be seen from the evaluation results of solid stability, crystal form A exhibited excellent physical and chemical properties under all conditions of high temperature, high humidity, and strong light irradiation.

[0404] (Example 10: Study on hygroscopic properties)

[0405] The important hygroscopic properties of this compound were tested using a dynamic measurement method, a dynamic water vapor adsorption (DVS) system. During the measurement, the sample weight changed, and as with other research methods, the DVS recorded the change in sample mass as the sample changed with relative humidity. The relevant spectral diagrams can be found in Figures 15-16. As can be seen from the DVS curve results shown in Figure 15, the initial water adsorption of the sample in the two adsorption / desorption curves at 25°C / 90%RH (relative humidity) was less than 0.04% in both cases, indicating that the sample has low hygroscopicity.

[0406] [Table 58]

[0407] Conclusion: XRPD testing was performed on samples before and after DVS testing. As can be seen from Figure 16, the crystal form did not change.

[0408] (Example 11: Preparation of salt mold)

[0409] Free bases possess multiple basic sites, and we selected inorganic / organic acids and free bases commonly used in drug research to study salt formation. Nine different salts, including hydrochloride, sulfate, and phosphate salts, were prepared in the study. The experimental process for salt formation is summarized below.

[0410] (1) API (i.e., the 5-membered condensed 6-membered compound represented by formula I prepared in Example 1) (30 mg) and solvent (0.3 mL) were placed in a reaction flask. The reaction system was stirred at room temperature (approximately 25°C) to obtain a clear solution or suspension. (2) First, the counterion reagent (1.1 eq. or 3.0 eq.) and solvent (0.3 mL) were placed in a reaction flask and stirred at room temperature to obtain a clear solution or suspension. Then, under stirring conditions, this system was slowly added to the clear solution or suspension from (1). (3) The reaction system was heated to 50°C and stirred at 50°C for 2 hours. (4) The reaction system was cooled to 25°C at a cooling rate of 10°C / hour and held there for 15 hours. (5) The suspension reaction system was centrifuged, and the filtered cake was vacuum-dried at room temperature for 15 hours. For reaction systems in which no solid precipitate was formed, the solvent was evaporated by purging with nitrogen gas at 25°C to obtain a solid sample. The results are as follows.

[0411] [Table 59]

[0412] [Table 60]

[0413] Note: Samples marked with "*" indicate a solid obtained by evaporating a clear solution under a nitrogen atmosphere, while " / / " indicates that evaporation did not occur or only a small amount of solid was obtained.

[0414] In the table, HC represents hydrochloride, SF represents sulfate, PH represents phosphate, NA represents sodium salt, and KA represents potassium salt.

[0415] Based on nine different salt forms that could be obtained, and considering the characterization results by XRPD, TGA, and DSC, the crystallinity, melting point, and weight loss by TGA of the salts were comprehensively compared, and hydrochloride crystal form A (HC-crystal form A), sulfate crystal form A (SF-crystal form A), and phosphate crystal form A (PH-crystal form A) were selected as the dominant salt forms, and subsequent solid stability tests and DVS hygroscopicity tests were conducted.

[0416] (Example 12: Detection of salt type)

[0429] 5.6 Experimental Results

[0430] [Table 65]

[0431] Calculation: The molar ratio of chloride ions to free base in the hydrochloride salt is (5.95 / 35.5) / (100 / (517.5+36.5))=0.93:1. The molar ratio of sulfate to free base in a sulfate solution is (15.67 / 96) / (100 / (517.5+98))=1:1. The molar ratio of phosphate to free base in a phosphate is (14.98 / 95) / (100 / (517.5+98))=0.97:1.

[0432] Conclusion: The results of the verification showed that the acid-base ratio of all the salts obtained above was 1:1.

[0433] (Example 13: Characterization of crystal form)

[0434] The solid salts obtained through screening were characterized using methods such as differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and powder X-ray diffraction (XRPD). Based on a comprehensive consideration of the crystallinity, TGA loss, melting point, and HPLC purity of the salts obtained through screening, a superior salt type was selected, and scale-up preparation was carried out.

[0435] The solid properties of the salt-type obtained through screening were characterized using methods such as differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and powder X-ray diffraction (XRPD). Relevant spectral diagrams can be found in Figures 17-34. The experimental results are as follows.

[0436] [Table 66]

[0437] (Example 14: Solid Stability Test)

[0438] 60 mg each of hydrochloride crystalline form A, sulfate crystalline form A, and phosphate crystalline form A were weighed out and placed in glass dishes or vials. Next, the glass dishes or vials were placed in different environments within a constant temperature and humidity chamber, including light irradiation: 4500 ± 500 lux (open), high temperature: 60°C (closed), high humidity: 25°C, relative humidity 90 ± 5% (open).

[0439] The results of the solid stability studies of phosphates, hydrochlorides, and sulfates are shown below.

[0440] [Table 67]

[0441] As can be seen from the results of the solid stability evaluation test, hydrochloride crystalline form A showed good physical and chemical stability under all conditions of strong light irradiation, high temperature, and high humidity.

[0442] (Example 15: Solubility Test)

[0443] The solubility of the dominant salt was measured in different pH buffers, water, and physiological saline. The specific steps for solubility measurement are as follows:

[0444] 15 mg of each hydrochloride crystal form A sample was accurately weighed out and transferred to a 20 mL screw-top vial. 3 mL of the solution (water, pH buffer, SGF, FaSSIF, FeSSIF) was added to each vial. The vials were sealed and placed in a magnetic stirrer, where they were maintained at 25°C and a stirring speed of 500 rpm for 24 hours. The solubility of the samples in the vials was recorded during the test period. After 24 hours, approximately 1 mL of the suspension was filtered, the filtrate was collected, and a solubility test was performed by HPLC. The pH value of the filtrate sample was measured using a pH meter. Phosphate crystal form A and sulfate crystal form A were determined according to the above procedure.

[0445] The experimental results are summarized in the table below.

[0446] [Table 68]

[0447] As the results show, all crystalline forms exhibited good solubility in a pH 1 buffer solution.

[0448] (Example 16: DVS test)

[0449] Experimental method: 1. First, the weight of the instrument's sample tray was set to zero to achieve equilibrium. 2. 30 mg of each sample (phosphate crystalline form A and hydrochloride crystalline form A) was weighed out and placed in a sample tray. 3. Program operation: Starting from a point where the humidity was 0%, the first cycle was completed when the humidity slowly increased to 90% and then returned to 0%. The second cycle was completed when the humidity increased again to 90% and then returned to 0% (as shown in Figures 35-36).

[0450] The results of the DVS data are shown in the following table.

[0451] [Table 69]

[0452] As can be seen from the test results, both hydrochloride crystalline form A and phosphate crystalline form A have low hygroscopicity, and no changes were observed in the samples before and after the DVS test.
