[0002] The present invention belongs to the field of pharmaceutical chemistry, and specifically relates to crystal polymorphs of GLP-1R agonist compounds, their production methods and uses.

Background Art

[0003] Diabetes is a chronic disease characterized by hyperglycemia caused by insufficient insulin secretion (relative or absolute) or insulin action disorder in the human body. According to the 9th edition of the World Diabetes Atlas newly released by the International Diabetes Federation (IDF), in 2019, approximately 463 million adults (aged 20-79) worldwide suffered from diabetes, and it is expected that the number of diabetes patients will reach 578 million in 2030. If this trend continues, there will be 700 million diabetes patients worldwide in 2045. Therefore, diabetes has become one of the most serious social health problems faced worldwide in the 21st century.

[0004] Currently, there are various pharmacological methods for treating hyperglycemia and associated T2DM (Hampp et al., "Use of Antidiabetic Drugs in the U.S.", 2003 - 2012, Diabetes Care 37:1367 - 1374, 2014). These methods can be classified into six major classes, and each class acts by different major mechanisms.

[0005] Insulin secretagogues include sulfonylureas, dipeptidyl peptidase IV (PP-IV) inhibitors, and glucagon-like peptide-1 receptor (GLP-1R) agonists, which act on pancreatic β-cells to improve insulin secretion. Sulfonylureas have limited efficacy and tolerability, cause weight gain, and often induce hypoglycemia. DP-IV inhibitors have limited efficacy. Commercially available GLP-1R agonists are peptides administered by subcutaneous injection, and liraglutide is approved for the treatment of obesity.

[0006] Biguanides (e.g., metformin) are thought to act mainly by reducing glucose production in the liver. Biguanides often cause gastrointestinal discomfort and lactic acidosis, and their use is further restricted.

[0007] α-Glucosidase inhibitors (e.g., acarbose) reduce intestinal glucose absorption. These drugs often cause gastrointestinal discomfort.

[0008] Thiazolidinediones (e.g., pioglitazone, rosiglitazone) act on specific receptors in the liver, muscle, and adipose tissue. They regulate lipid metabolism and subsequently enhance the response of these tissues to insulin action. Frequent use of these drugs can cause weight gain and may induce edema and anemia.

[0009] Insulin, when used alone or in combination with the above drugs in more severe cases and when used frequently, can cause weight gain and may also pose a risk of hypoglycemia.

[0010] Sodium-glucose co-transporter 2 (SGLT2) inhibitors (e.g., dapagliflozin, empagliflozin, canagliflozin, ertugliflozin) inhibit glucose reabsorption in the kidney and thereby reduce blood glucose content. Such a new class of drugs may be associated with ketoacidosis and urinary tract infections.

[0011] However, except for GLP-1R agonists and SGLT2 inhibitors, the efficacy of the above drugs is limited, and the most important problems of β-cell function decline and correlated obesity have not been solved. Therefore, there is a need for more effective drug intervention with relatively few side effects and convenient administration.

[0012] GLP-1 is an incretin hormone 30 amino acids in length secreted by intestinal L cells in response to food intake. GLP-1 has been shown to stimulate insulin secretion physiologically and glucose-dependently, reduce glucagon secretion, inhibit gastric emptying, decrease appetite, and stimulate β-cell proliferation. In preclinical studies, GLP-1 promotes sustained β-cell capacity by stimulating important gene transcription for glucose-dependent insulin secretion and promoting β-cell neogenesis (Meier et al., "Biodrugs." 17(2):93-102, 2013).

[0013] In healthy individuals, GLP-1 plays an important role in regulating postprandial blood glucose levels by stimulating glucose-dependent insulin secretion in the pancreas, thereby increasing peripheral glucose absorption. GLP-1 also inhibits glucagon secretion and reduces glucose output from the liver. In addition, GLP-1 delays gastric emptying and slows intestinal motility to delay food absorption. In people with T2DM, postprandial GLP-1 either does not rise normally or the amount of increase decreases (Vilsbol1 et al., "Diabetes," 50:609-613, 2001).

[0014] Scientific research has appropriately modified and optimized the structure of GLP-1 to increase its half-life and further extend its in vivo biological effects. However, currently clinically used long-acting GLP-1 analogs, such as liraglutide and exenatide, are all polypeptides, and due to the relatively poor patient compliance caused by frequent multiple injections, the development of small molecule GLP-1R agonists has broad clinical market prospects for the purposes of improving patient compliance, dosing convenience, and reducing drug side effects.

[0015] Hangzhou Deruizhi Pharmaceutical Technology Co., Ltd. (Mindrank AI Ltd.) has developed small molecule compounds with novel structures and strong agonist activity for GLP-1R. Among them, the compound with the chemical name (S)-2-(4-(6-(4-chloro-2-fluorophenoxy)methyl)pyridin-2-yl)oxy)piperidin-1-yl)methyl)-1-(oxetan-2-ylmethyl)-1H-benzo[d]imidazole-6-carboxylic acid, and the compound with the chemical name (S)-2-(4-(6-(4-cyano-2-fluorophenoxy)methyl)pyridin-2-yl)oxy)piperidin-1-yl)methyl)-1-(oxetan-2-ylmethyl)-1H-benzo[d]imidazole-6-carboxylic acid have strong agonist activity and good drug development potential, and their structures are as follows.

[0016] [Chemical Structure]

[0017] The free compounds of formula (I) and formula (II) have been identified as amorphous compounds by the inventors. They are prone to moisture absorption or softening, and are likely to undergo crystalline form transformation during long-term storage, which is inconvenient for the development of clinical formulations. To meet the needs of clinical research and commercially available pharmaceutical formulations, the development of an aggregated form suitable for drug development to overcome the defects existing in the prior art is eagerly desired.

[0018] Success in the development of the solid form of a drug usually means having a solid form that can be conveniently separated and purified after synthesis, applicable to industrial production, capable of relatively long-term storage and minimal water absorption, capable of decomposition or transformation into other solid forms, and applicable to properties such as a dosage form that can be rapidly absorbed by an individual after administration (for example, soluble in water and gastric juice). To meet the needs of clinical research and commercially available pharmaceutical formulations, the development of a drug solid form that can be conveniently separated and purified, applicable to industrial production, and has stable physicochemical properties is eagerly desired.

Mode for Carrying Out the Invention

[0401] Definition and Explanation of Terms Unless otherwise stated, the following terms used in the specification and claims have the following meanings. A particular phrase or term should not be considered uncertain or unclear when not specifically defined, but should be understood in its ordinary meaning. When a trade name is described in this specification, it is intended to refer to the corresponding product or its active ingredient.

[0402] "Pharmaceutical composition" refers to a mixture of one or more compounds described in this specification or their physiological / pharmaceutically acceptable salts or prodrugs with other chemical components, as well as other components such as physiological / pharmaceutically acceptable carriers and excipients. The pharmaceutical composition is intended to facilitate administration to a living body, contribute to the absorption of the active ingredient, and further exert biological activity.

[0403] As used herein, "crystalline polymorph" refers to crystal forms that have the same chemical composition but different spatial arrangements of the molecules, atoms, and / or ions that make up the crystal. Crystalline polymorphs have the same chemical composition, but their packing and geometric arrangements are different, and they may exhibit different physical properties such as melting point, shape, color, density, hardness, deformability, stability, solubility, dissolution rate, and similar properties. Two crystalline polymorphs may be monotropic or enantiotropic depending on their temperature-stability relationship. In a monotropic system, the relative stability between the two solid phases does not change as the temperature changes. In contrast, in an enantiotropic system, there is a transition temperature at which the stability of the two phases switches (Theory and Origin of Polymorphism in "Polymorphism in Pharmaceutical Solids" (1999) ISBN: -8247-0237). The phenomenon in which such compounds exist in different crystal structures is called drug crystal polymorphism.

[0404] The various crystal structures of the present invention can be distinguished from each other using various analytical techniques known to those skilled in the art. Such techniques include, but are not limited to, X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), and / or thermogravimetric analysis (TGA).

[0405] As used herein, the term "room temperature" or "RT" refers to an environmental temperature of 20-25°C (68-77°F).

[0406] The term "substantially identical" with respect to X-ray diffraction peak positions as used herein means taking into account typical peak positions and intensity variability. For example, as would be understood by one of ordinary skill in the art, the peak position (2θ) can vary in the measured values due to differences in XRPD equipment, and sometimes such variations can reach up to 0.2°. Otherwise, as would be understood by one of ordinary skill in the art, factors such as the method of manufacturing the XRPD sample, the XRPD equipment, the crystallinity of the sample, the amount of sample used, and the preferred orientation of the crystal can result in changes in the relative peak intensities in the sample XRPD diffraction pattern.

[0407] The intermediate compounds according to the present invention can be prepared by a plurality of synthetic methods well known to those skilled in the art, including the specific embodiments listed below, the embodiments formed by combinations with other chemical synthesis methods, and equivalent alternative methods well known to those skilled in the art. Preferred embodiments include, but are not limited to, the examples of the present invention.

[0408] The chemical reactions of the specific embodiments of the present invention are completed in a suitable solvent, and the above solvent must be suitable for the chemical changes of the present invention and its necessary reagents and materials. In order to obtain the compounds of the present invention, those skilled in the art may need to modify or select the synthetic steps or reaction processes based on the existing embodiments.

[0409] Hereinafter, the present invention will be specifically described by way of examples, but these examples do not limit the present invention.

[0410] All solvents used in the present invention are commercially available and can be used without further purification.

[0411] Unless otherwise specified, all reactions of the present invention are carried out with continuous magnetic stirring, the solvent is a dry solvent, and the temperature unit is degrees Celsius (°C).

[0412] Methods and Materials The structure of the compound is determined by nuclear magnetic resonance (NMR). The NMR shift (δ) is expressed in parts per million (ppm). For NMR measurement, a Bruker avance-400 MHz nuclear magnetic device is used, the measurement solvent is deuterated dimethyl sulfoxide (DMSO-d6) or deuterated methanol (MeOD-d4), the internal standard is tetramethylsilane (TMS), and the chemical shift is 10 -6 ppm as the unit.

[0413] For HPLC measurement, an Agilent 1260 high-performance liquid chromatograph or a high-performance liquid chromatograph with equivalent efficacy (Sunfire C18 150×4.6 m column or a column with equivalent efficacy) is used.

[0414] The crystalline polymorphs of Compound III are characterized by X-ray powder diffraction patterns. The X-ray powder diffraction patterns of the above salts are collected on a Bruker D8 Advance powder diffractometer operating in reflection mode using Cu Kα radiation. The instrument employs Cu Kα irradiation (40 kV, 40 mA) and is performed at room temperature using an SSD160-2 detector. The scanning range is 3° to 40° in the 2θ interval, and the scanning speed is 0.1 s / step. The diffraction patterns are analyzed using DIFFRAC.MEA.CENTER software.

[0415] The production of XRPD samples is carried out by placing the sample on a single-crystal silicon wafer and pressing the sample powder with a glass plate or equivalent to ensure that the surface of the sample is flat and has an appropriate height. Next, the sample holder is placed in a Bruker D8 Advance instrument, and an X-ray powder diffraction pattern is collected using the above instrument parameters. The differences in measurements correlated with such X-ray powder diffraction analysis results arise from multiple factors, including (a) errors in the sample product (e.g., the height of the sample), (b) instrument errors, (c) calibration differences, (d) operator errors (including errors occurring when measuring peak positions), and (e) the nature of the substance (e.g., preferred orientation error). Calibration errors and sample height errors always result in a shift in the same direction for all peaks. Generally, this calibration coefficient can match the measured peak position with the predicted peak position and be within the range of the predicted 2θ value ±0.2°.

[0416] The experimental method for characterizing the crystalline form of the acidic or basic salt of Compound III using differential scanning calorimetry (DSC) is to take a small amount of the crystalline polymorph of Compound III, set it up with the instrument, place it in a capping-capable aluminum crucible, cap it with an aluminum disk after placing the sample, and then send it into the instrument for detection. The model number of all instruments used in the differential scanning calorimetry method in the present invention is METTLER TOLEDO DSC 3, and the scanning parameters are provided such that a nitrogen gas atmosphere is adopted and the heating rate is 10.0 k / min.

[0417] The experimental method for characterizing the crystalline polymorph of Compound III using thermogravimetric analysis (TGA) is to take a small amount of the powder of the crystalline polymorph of Compound III, place it in an alumina crucible set up with the instrument, and send it into the instrument for detection after placing the sample. The model number of all instruments used in the differential scanning calorimetry method in the present invention is METTLER TOLEDO TGA 2, and the scanning parameters are provided such that a nitrogen gas atmosphere is adopted and the heating rate is 10.0 k / min.

[0418] The experimental method for characterizing the acidic or basic salts of Compound III using the dynamic vapor sorption (DVS) method is to take a small amount of the powder of the crystalline polymorphs of Compound III, place it in a precision sample tray that is set up with the instrument, and after placing the sample, send it into the instrument for detection. The model number of all the instruments used in the dynamic vapor sorption method in the present invention is Intrinsic PLUS. The experimental parameters are set such that the constant temperature is 25 °C, and the criterion for determining equilibrium attainment is that the mass percentage change rate per unit time (dm / dt) = 0.02% / min, and the programmed humidity change cycle is set such that the initial relative humidity is 0% and the relative humidity at the end point is 90%.

[0419] [Embodiments for Carrying Out the Invention] Hereinafter, in accordance with specific examples, the technical solutions of the present invention will be described in more detail. It should be understood that the following examples are merely illustrative explanations and interpretations of the present invention and should not be construed as limiting the scope of the claims of the present invention. Any technology realized based on the above content of the present invention is included within the scope of the claims of the present invention.

In the test, the solid was prepared as a suspension (~10 mg / mL) in the corresponding buffer solution and mixed at 37 ± 2 °C. After 24 hours, the suspension was sampled, the supernatant was filtered, the concentration was measured, and XRPD measurement of the solid was performed. The detection results are shown in the following table.

[0435]

Table 47

[0436] As can be seen from the above experimental results, the crystalline form D of Compound I is clearly superior in stability in a biological medium to the amorphous solid of Compound I. In the FaSSGF system, except that the crystalline form changed to the hydrochloride, no change in the crystalline form was observed in any of the other samples. Its solubility in the FaSSIF system was also clearly improved, and it can meet the requirements for the clinical formulation development of the drug. Therefore, the free form of Compound I can obtain remarkable improvements in terms of solubility and drug release behavior after salt formation.

The changes in HPLC purity and crystalline form were measured to examine the solid stability, and the results are shown in the following table.

[0438]

Table 48

[0439] As can be seen from the above experimental results, for the amorphous solid of Compound I, there was no obvious change in purity after standing for 7 days under long-term conditions, but significant decomposition occurred after 7 days under accelerated and high-temperature conditions. For the crystalline form D of Compound I, there was no obvious change in purity after standing for 7 days under long-term conditions, and there was only a slight decrease after standing for 7 days under accelerated and high-temperature conditions, and no obvious change in the crystalline form. The stability of the crystalline form D is clearly superior to that of the amorphous solid.

The DVS pattern of the amorphous solid of the compound is shown in Figure 67, and the DVS pattern of the crystalline form D of the compound is shown in Figure 68. The obtained results are shown in the following table.

[0442] As can be seen from the above experimental results, in the adsorption curve of 0 - 90% RH, at the condition of 80% RH, both the amorphous solid of Compound I and the sample of Crystal Form D were slightly hygroscopic, with no obvious difference, and no change in the solid form was observed for either of them.
