Description

Technical Field

[0001] This application belongs to the field of biomedical technology, specifically relating to a compound for inhibiting PTPN protein and its use, and more specifically to a compound for inhibiting PTPN protein, a PTPN protein inhibitor, a pharmaceutical composition and their use. Background Technology

[0002] PTPN proteins are a class of non-receptor protein tyrosine phosphatases that play an important role in cell signaling, such as regulating cell growth, development, differentiation, survival, and migration. Some members of the PTPN family, such as PTPN1, PTPN2, PTPN12, and PTPN22, have potential roles in cancer immunotherapy, and their expression in esophageal cancer, gastric cancer, and colorectal cancer is associated with disease development.

[0003] PTPN2 (also known as TCPTP or T-cell protein tyrosine phosphatase) plays a synergistic anti-inflammatory role in various inflammatory cells and regulates the development and differentiation of immune cells. Furthermore, PTPN2 expression levels are closely related to the occurrence and prognosis of certain cancers; for example, in pancreatic adenocarcinoma, high PTPN2 expression is associated with a poor prognosis and may promote cancer progression by activating the JAK-STAT signaling pathway.

[0004] PTPN1 (protein tyrosine phosphatase 1, also known as T-cell protein tyrosine phosphatase) plays a crucial role in regulating cell signaling, such as in the activation, proliferation, and differentiation of immune cells. PTPN1 participates in regulating intracellular signaling by dephosphorylating various substrate proteins, particularly in T-cell development and function. Furthermore, PTPN1 expression levels are upregulated in certain cancers, potentially related to tumor cell proliferation, survival, and metastasis.

[0005] Therefore, the development of PTPN protein inhibitors holds potential for treating diseases such as cancer. Summary of the Invention

[0282] In this paper, the PROTAC drug consists of two protein-binding moieties: one for binding to an E3 ubiquitin ligase and the other for binding to a target protein (PTPN protein in this application). PROTAC binds to the PTPN protein and carries it to the E3 ubiquitin ligase. After the formation of the tertiary complex, the E3 ubiquitin ligase transfers ubiquitin to the surface lysine residue of the target protein, resulting in a ubiquitinated target protein destined for degradation by the proteasome machinery. Following ubiquitination, PROTAC is released and continues to search for PTPN proteins for ubiquitination and degradation.

[0283] It should be noted that the linker described above is used to connect the compound and the ubiquitin ligand, and the ubiquitin ligand is used to bind to E3 ubiquitin ligand. Therefore, the linker and ubiquitin ligand in this application are not particularly limited, as long as they can achieve the above functions. The E3 ubiquitin ligand can be a peptide or small molecule capable of binding to E3 ubiquitin ligand, and its specific type is not limited.

[0313] Figure 1 This describes the tumor-suppressing effect of an example compound in mice according to an embodiment of the present invention. Detailed Implementation

[0314] The embodiments of this application are described in detail below. The embodiments described below are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0315] Definitions and General Terms

[0316] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0317] It should be noted that the structural and chemical formula descriptions in the embodiments or implementations of this application are intended to cover all alternatives, modifications, and equivalent technical solutions, all of which are within the scope of this application as defined in the claims. Those skilled in the art will recognize that many similar or equivalent methods and materials can be used to practice this application. This application is by no means limited to the methods and materials described herein. In the event that one or more of the cited documents, patents, and similar materials differ from or contradict this application (including but not limited to defined terminology, application of terminology, described techniques, etc.), this application shall prevail.

[0318] It should be further appreciated that some features of this application, for clarity, have been described in multiple independent embodiments or implementations, but may also be provided in combination in a single embodiment or implementation. Conversely, various features of this application, for the sake of brevity, have been described in a single embodiment or implementation, but may also be provided individually or in any suitable sub-combination.

[0319] Unless otherwise stated, the technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains, and unless otherwise stated, all patent publications cited in the entirety of this application are incorporated herein by reference.

[0320] Unless otherwise stated, the following definitions will apply in this application. For the purposes of this application, chemical elements are defined according to the periodic table, CAS version, and the Chemical Handbook, 75th Ed, 1994. Furthermore, general principles of organic chemistry are found in "Organic Chemistry," Thomas Sorrell, University Science Books, Sausalito: 1999, and "March's Advanced Organic Chemistry," by Michael B. Smith and Jerry March, John Wiley & Sons, New York: 2007; therefore, all contents of this application incorporate the references.

[0321] In this document, the terms “comprising” or “including” are open-ended expressions, meaning that they include the contents specified in this application but do not exclude other contents.

[0322] In this document, the compounds of this application also include isotopically labeled compounds of this application that are identical to those compounds described herein except that one or more atoms are replaced by atoms with atomic masses or mass numbers different from those of naturally common atomic masses or mass numbers. Exemplary isotopes that may also be introduced into the compounds of this application include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, such as... 2 H, 3 H, 13 C 14 C 15 N、 16 O、 17 O、 31 P, 32 P, 36 S, 18 F and 37 Cl.

[0323] Compounds of this application containing other isotopes of the aforementioned isotopes and / or other atoms, as well as pharmaceutically acceptable salts of said compounds, are included within the scope of this application. Isotope-labeled compounds of this application, such as radioactive isotopes, are also included. 3 H and 14 The incorporation of tritium into the compounds of this application can be used for drug and / or substrate tissue distribution analysis. Due to its ease of preparation and detection, tritium-substituted compounds... 3 H, and carbon-14, i.e. 14 C isotopes are particularly preferred. In addition, heavier isotopes, such as deuterium, are used. 2 H substitution can offer therapeutic advantages stemming from greater metabolic stability, such as increased in vivo half-life or reduced dose requirements. Therefore, it may be preferred in some cases.

[0324] The stereochemical definitions and conventions used in this application are generally in accordance with S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984), McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., “Stereochemistry of Organic Compounds,” John Wiley & Sons, Inc., New York, 1994. The compounds of this application may contain asymmetric or chiral centers and thus exist in different stereoisomeric forms. It is contemplated that all stereoisomeric forms of the compounds of this application, including but not limited to diastereomers, enantiomers, and atropisomers, and mixtures thereof such as racemic mixtures, are also included within the scope of this application. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L or R and S are used to indicate the absolute configuration of the molecule with respect to the chiral center (or multiple chiral centers) in the molecule. The prefixes d and l, or (+) and (-), are symbols used to specify the plane-polarized rotation caused by a compound, where (-) or l indicates that the compound is levorotatory. Compounds prefixed with (+) or d are dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. Specific stereoisomers may also be called enantiomers, and mixtures of such isomers are generally called mixtures of enantiomers. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which may occur when there is no stereoselectivity or stereospecificity in a chemical reaction or method.

[0325] Depending on the choice of raw materials and methods, the compounds of this application may exist as one or a mixture of possible isomers, for example, as pure optical isomers, or as mixtures of isomers, such as as racemic and non-corresponding isomer mixtures, depending on the number of asymmetric carbon atoms. Optically active (R)- or (S)- isomers can be prepared using chiral synthons or chiral formulations, or resolved using conventional techniques. If the compound contains a double bond, the substituent may be E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the cycloalkyl substituent may be cis or trans (cis- or trans-) configuration.

[0625] Test Example 6: Detection of the inhibitory effect of various compounds on hERG

[0626] The experimental steps are as follows:

[0627] Compound preparation:

[0628] The weighed analyte was prepared into a 10 mM stock solution using DMSO. The stock solution was then sequentially diluted with DMSO to prepare 3.33 mM, 1 mM, 0.33 mM, and 0.1 mM diluents. The stock solution and diluents were then sequentially diluted with extracellular fluid to prepare 30 μM, 10 μM, 3 μM, 1 μM, and 0.3 μM working solutions, ensuring a DMSO concentration of 0.3%. All concentrations were sonicated for 20 min. The solubility of the sample was visually inspected; all concentrations dissolved completely without any visible precipitation.

[0629] Cell culture

[0630] The HEK-293 cell line, stably expressing hERG potassium channels, was used. These hERG potassium channel cells were purchased from Creacell (catalog number: A-0320). The cell culture method is as follows:

[0631] HEK-293 cell lines stably expressing hERG potassium channels were cultured in DMEM medium containing 10% fetal bovine serum and 0.8 mg / mL G418 at 37°C and 5% carbon dioxide.

[0632] Cell passage: Remove the old culture medium and wash once with PBS, then add 1 mL TrypLE TM Incubate with Express solution at 37°C for approximately 0.5 min. Once cells detach from the bottom of the dish, add approximately 5 mL of preheated (37°C) complete culture medium. Gently pipette the cell suspension to separate any aggregated cells. Transfer the cell suspension to sterile centrifuge tubes and centrifuge at 1000 rpm for 5 min to collect the cells. For expansion or maintenance culture, seed cells into 6 cm cell culture dishes at a density of 2.5 × 10⁶ cells per dish. 5 Cells (final volume: 5 mL). To maintain the electrophysiological activity of the cells, the cell density must not exceed 80%.

[0633] Before patch-clamp detection, cells were treated with TrypLE. TM Express separation, 4×10 3 Cells were seeded onto coverslips and cultured in 24-well plates (final volume: 500 μL). After 18 hours, the cells were tested.

[0634] Electrophysiological recording

[0635] Record the liquid used

[0636] Extracellular fluid: K-007-1

[0637] 140mM NaCl, 3.5mM KCl, 1mM MgCl2·6H2O, 2mM CaCl2·2H2O, 10mM D-Glucose, 10mM HEPES, 1.25mM NaH2PO4·2H2O, with NaOH adjusted to pH 7.4.

[0638] Intracellular fluid: K-002-2

[0639] 20mM KCl, 115mM K-Aspartic, 1mM MgCl2·6H2O, 5mM EGTA, 10mM HEPES, 2mM Na2-ATP, KOH adjust pH=7.2.

[0640] Extracellular fluid was stored for 2 weeks. Intracellular fluid, after preparation, was aliquoted into 1 mL tubes and stored at -20°C. Freshly thawed intracellular fluid was used daily for experiments. All intracellular fluid was used within three months. After three months, the old intracellular fluid was discarded and freshly prepared.

[0641] Patch clamp testing

[0642] The voltage stimulation protocol for whole-cell patch-clamp recording of hERG currents is as follows: After whole-cell sealing, the cell membrane voltage is clamped at -80 mV. The clamping voltage is depolarized from -80 mV to -50 mV and maintained for 0.5 s (as a leakage current detection), then stepped to 30 mV and maintained for 2.5 s, and then rapidly restored to -50 mV and maintained for 4 s to excite the tail current of the hERG channel. Data is collected every 10 s to observe the effect of the drug on the hERG tail current. Experimental data are acquired by an IPA amplifier (Sutter Instrument) and stored in SutterPatch (with Igor Pro) software. The patch-clamp procedure first involves using a microelectrode puller to pull a capillary glass tube into a recording electrode, then inserting the electrode filled with intracellular fluid into the microelectrode holder. Under an inverted microscope, the microelectrode manipulator is used to immerse the electrode in the extracellular fluid and record the electrode resistance (Rpip). Then, the electrode is slowly brought into contact with the cell surface, and negative pressure is applied to aspirate and form a GΩ seal. Fast capacitance compensation is then performed, and negative pressure is applied to rupture the cell membrane, establishing a whole-cell recording mode. Finally, slow capacitance compensation is performed, and experimental parameters such as series resistance (Rs) are recorded. No leakage compensation is applied. Once the hERG current recorded in the whole cells stabilizes, drug administration begins. Each drug concentration is administered for approximately 5 minutes (or until the current stabilizes), and the next concentration is measured. Multiple concentrations are measured for each test compound. A coverslip containing cells is placed in a recording bath under an inverted microscope. Blank control solution and working solution of the test compound are perfused sequentially from low to high concentration through the recording bath using gravity, acting on the cells. A peristaltic pump is used for fluid exchange during recording. The current detected in the solution without the compound serves as the control group for each cell. Each concentration is measured twice independently using at least two cells. All electrophysiological experiments are performed at room temperature.

[0643] Data Analysis

[0644] First, the peak tail current after each drug concentration was applied was recorded. compound Peak tail current (and blank control) control Normalize, and then calculate the inhibition rate corresponding to each drug concentration. For each concentration inhibition rate, the mean (Mean), standard deviation (SD), and standard error (SE) were calculated, and the data are expressed as Mean ± SE.
