Description

[0001] This application claims priority to a Chinese patent application filed with the State Intellectual Property Office of China on January 30, 2022, with application number 202210115506.1 and invention name “Wnt pathway inhibitor compounds”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to a heterocyclic compound, in particular to a highly active Wnt pathway inhibitor and application thereof. Background Art

[0003] The Wnt / β-catenin signal transduction pathway is a conserved pathway in biological evolution. In normal somatic cells, β-catenin only functions as a cytoskeletal protein to form a complex with E-cadherin at the cell membrane to maintain the adhesion of homotypic cells and prevent cell movement. When the Wnt signaling pathway is not activated, β-catenin in the cytoplasm is phosphorylated and forms a β-catenin degradation complex with APC, Axin, and GSK3β, thereby initiating the ubiquitin system to degrade β-catenin via the proteasome pathway, maintaining β-catenin in the cytoplasm at a low level. When cells are stimulated by Wnt signals, Wnt proteins bind to the specific receptor Frizzled protein on the cell membrane. The activated Frizzled receptor recruits intracellular Dishevelled protein, inhibits the degradation activity of the β-catenin degradation complex formed by GSK3β and other proteins, and stabilizes the free β-catenin protein in the cytoplasm. After β-catenin stably accumulated in the cytoplasm enters the cell nucleus, it binds to the LEF / TCF transcription factor family and initiates the transcription of downstream target genes (such as c-myc, c-jun, Cyclin D1, etc.). Overactivation of the Wnt / β-catenin signaling pathway is closely related to the occurrence of various cancers (including colon cancer, gastric cancer, breast cancer, etc.). For example, abnormal activation of the Wnt classical signaling pathway and nuclear accumulation of β-catenin protein are widely present in colorectal cancer, and the proliferation of cancers such as colon cancer can be inhibited by inhibiting the activity of the Wnt signaling pathway. APC mutations exist in more than 85% of colorectal cancers. The mutated APC blocks the phosphorylation and degradation of β-catenin, inducing the occurrence of colorectal cancer. In addition, Axin mutations and β-catenin mutations can also cause intracellular aggregation of β-catenin and activate the Wnt / β-catenin pathway.

[0004] Although it is known that inhibiting the Wnt signaling pathway can effectively prevent and / or treat cancer, tumors, inflammatory diseases, autoimmune diseases and immune-mediated diseases, there is currently a lack of satisfactory and effective Wnt pathway inhibitor compounds in the prior art. Therefore, the study of effective Wnt pathway inhibitor compounds is a need in the prior art. Summary of the invention

[0028]

[0029]

[0030]

[0031]

[0032]

[0033]

[0034] In another aspect of the present invention, a pharmaceutical composition is provided, comprising any of the aforementioned compounds or pharmaceutically acceptable salts, isotopic derivatives, stereoisomers thereof, and an optional pharmaceutically acceptable carrier.

[0035] In another aspect of the present invention, there is also provided the use of the aforementioned compound or its pharmaceutically acceptable salt, isotope derivative, stereoisomer or the aforementioned pharmaceutical composition in the preparation of a medicament for preventing and / or treating cancer, tumor, inflammatory disease, autoimmune disease or immune-mediated disease.

[0036] It is specifically noted that, herein, when referring to a "compound" of the structure of Formula I, stereoisomers, diastereomers, enantiomers, racemic mixtures and isotopic derivatives thereof are generally also encompassed.

[0037] It is well known to those skilled in the art that a salt, solvate, or hydrate of a compound is an alternative form of the compound, and they can all be converted into the compound under certain conditions.

The salts may be prepared in situ during the final isolation and purification of the compounds of the present invention, or separately by reacting the free base or free acid with a suitable reagent, as outlined below. For example, the free base function may be reacted with a suitable acid. Examples of pharmaceutically acceptable inorganic acid addition salts are salts formed of an amino group with an inorganic acid (e.g., hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid) or an organic acid (e.g., acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid), or by using other methods known in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, sodium alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate and the like.

[0040] The pharmaceutically acceptable salts of the present invention can be prepared by conventional methods, for example, by dissolving the compound of the present invention in a water-miscible organic solvent (e.g., acetone, methanol, ethanol and acetonitrile), adding an excess of an organic acid or an aqueous inorganic acid solution thereto to precipitate the salt from the resulting mixture, removing the solvent and the remaining free acid therefrom, and then isolating the precipitated salt.

[0041] The precursors or metabolites of the present invention may be precursors or metabolites known in the art, as long as the precursors or metabolites are converted into compounds through in vivo metabolism. For example, "prodrugs" refer to those prodrugs of the compounds of the present invention, which are suitable for contact with human and lower animal tissues within the scope of reasonable medical judgment, without undue toxicity, irritation, allergic reactions, etc., and are considered to have a reasonable benefit / risk ratio and are effective for their intended use. The term "prodrug" refers to a compound that is rapidly converted in vivo to produce the parent compound of the above formula, for example, by in vivo metabolism, or N-demethylation of the compounds of the present invention.

[0042] "Solvate" as used herein means a physical association of a compound of the invention with one or more solvent molecules (whether organic or inorganic). The physical association includes hydrogen bonding. In some cases, for example, when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid, the solvate will be able to be separated. The solvent molecules in the solvate may exist in a regular arrangement and / or a disordered arrangement. The solvate may contain stoichiometric or non-stoichiometric amounts of solvent molecules. "Solvate" encompasses solution phases and separable solvates. Exemplary solvates include, but are not limited to, hydrates, ethanolates, methanolates, and isopropanolates. Solvation methods are well known in the art.

[0043] The "stereoisomerism" described in the present invention is divided into conformational isomerism and configurational isomerism. Configurational isomerism can also be divided into cis-trans isomerism and optical isomerism (i.e. optical isomerism). Conformational isomerism refers to a stereoisomerism phenomenon in which the atoms or atomic groups of molecules have different arrangements in space due to the rotation or distortion of carbon and carbon single bonds in organic molecules with a certain configuration. Common structures include the structures of alkane and cycloalkane compounds, such as the chair conformation and boat conformation that appear in the structure of cyclohexane. "Stereoisomer" refers to when the compounds of the present invention contain one or more asymmetric centers, and thus can be used as racemates and racemic mixtures, single enantiomers, diastereomeric mixtures and single diastereoisomers. The compounds of the present invention have asymmetric centers, and each asymmetric center will produce two optical isomers. The scope of the present invention includes all possible optical isomers and diastereomeric mixtures and pure or partially pure compounds. The compounds described in the present invention can exist in the form of tautomers, which have different hydrogen connection points due to one or more double bond displacements. For example, a ketone and its enol form are keto-enol tautomers. Each tautomer and mixtures thereof are included in the compounds of the present invention. Enantiomers, diastereomers, racemates, mesomorphs, cis-trans isomers, tautomers, geometric isomers, epimers and mixtures thereof of all compounds of formula (I) are included in the scope of the present invention.

[0044] The "isotopic derivative" of the present invention refers to a molecule in which the compound is isotopically labeled. The isotopes commonly used as isotopic labels are: hydrogen isotopes, 2 H and 3 H; Carbon isotope: 11 C, 13 C and 14 C; Chlorine isotope: 35 Cl and 37 Cl; Fluorine isotope: 18 F; Iodine isotope: 123 I and 125 I; Nitrogen isotopes: 13 N and 15 N; oxygen isotope: 15 Oh, 17 O and 18 O and sulfur isotopes 35 S. These isotope-labeled compounds can be used to study the distribution of drug molecules in tissues. 3 H and carbon 13 C, because they are easy to label and detect, they are more widely used. Some heavy isotopes, such as deuterium ( 2H), the substitution can enhance metabolic stability, prolong half-life and thus achieve the purpose of reducing dosage and provide therapeutic advantages. Isotope-labeled compounds are generally synthesized from labeled starting materials using known synthesis techniques in the same way as non-isotope-labeled compounds.

[0061] the term

[0062] If not otherwise stated, the terms used in this application, including the specification and claims, are defined as follows. If not otherwise stated, conventional methods of mass spectrometry, nuclear magnetic resonance, HPLC, protein chemistry, biochemistry, recombinant DNA technology and pharmacology are used. In this application, if not otherwise stated, the use of "or" or "and" means "and / or".

[0063] In the specification and claims, a given chemical formula or name shall encompass all stereoisomers and optical isomers thereof and racemates in which such isomers exist. Unless otherwise indicated, all chiral (enantiomers and diastereomers) and racemic forms are within the scope of the present invention. Multiple geometric isomers of C=C double bonds, C=N double bonds, ring systems, etc. may also exist in the compounds, and all such stable isomers are encompassed by the present invention. The present invention describes cis- and trans- (or E- and Z-) geometric isomers of the compounds of the present invention, and they can be separated into mixtures of isomers or separated isomeric forms. The compounds of the present invention can be separated in optically active or racemic form. All methods for preparing the compounds of the present invention and the intermediates prepared therein are considered to be part of the present invention. When enantiomeric or diastereomeric products are prepared, they can be separated by conventional methods (e.g., by chromatography or fractional crystallization). Depending on the process conditions, the final product of the present invention is obtained in free (neutral) or salt form. Both the free forms and salts of these end products are within the scope of the present invention. If desired, one form of the compound may be converted into another form. A free base or acid may be converted into a salt; a salt may be converted into a free compound or another salt; a mixture of isomeric compounds of the present invention may be separated into individual isomers. The compounds of the present invention, their free forms and salts may exist in a variety of tautomeric forms, in which hydrogen atoms are transposed to other parts of the molecule and the chemical bonds between the atoms of the molecule are rearranged. It should be understood that all tautomeric forms that may exist are included in the present invention.

[0064] Unless otherwise defined, the definitions of substituents of the present invention are independent of each other and not related to each other. For example (listing but not exhaustive), in one aspect, for R in a substituent a (or R a '), they are independent of each other in the definitions of different substituents. Specifically, for R a (or R a ') When a definition is selected for a substituent, it does not mean that the R a (or R a ') has the same definition in other substituents. More specifically, for example (only non-exhaustive) for NR a R a ', when R a (or R a ') is selected from hydrogen, it does not mean that in -C(O)-NR a R a ', R a (or R a ') must be hydrogen.

[0338] Wnt pathway inhibitor biological screening and results

[0339] Experimental Example 1: Construction of Colo205-LUC-TCF / LEF-M1 reporter cell line

[0340] The Colo205 cell line (Cell Bank of the Chinese Academy of Sciences, Cat#TCHu102) was purchased from the Cell Bank of the Chinese Academy of Sciences. After amplification and subculture, the cells were transfected with a luciferase reporter plasmid (Promega) driven by TCF / LEF transcription factors by lipo3000 liposome transfection during the exponential growth phase of the cells. This plasmid carries a resistance gene and can be screened for resistance. The transfection was carried out in a 10 cm culture dish using a conventional complete medium without resistance. After 2 days, the medium with resistance was replaced and culture continued. After that, the resistance medium was replaced every 2 days, and the suspended cells were discarded. The original medium was centrifuged to remove cells and debris and retained as an adaptive medium. When the cells filled the culture dish, the cells were digested, counted, and subcultured in a 96-well plate so that the average number of cells in each well was 1.5 / well. The adaptation medium was used during subculture. The remaining cells were frozen. After subculture, the cells were cultured for 4 hours to allow the cells to adhere to the wall, and then the number of cells in each well was observed under a microscope. The wells with only one cell in each well are marked, which are monoclonal wells. Then culture normally, change the culture medium every 2 days, and observe. In the early stage, the wells where monoclonal cells continue to grow are marked twice and can be replaced with normal resistant culture medium. When a monoclonal well fills the wells of the 96-well plate, it is digested and subcultured to a 24-well culture plate. After the 24-well plate is full, it is subcultured to a 96-well plate and a 6-well plate. There are at least 6 wells of cells in the 96-well plate, of which 3 wells are added with known Wnt inhibitors, and the other 3 wells are not treated. After 24 hours, the fluorescence detection reagent is added to the 96-well plate cells to detect the fluorescence intensity. Select the cell line that has fluorescence expression when not treated and the fluorescence light is reduced after inhibition, and further culture. The Colo205-LUC-TCF / LEF-M1 cell line is one of the cell lines screened above. Its growth curve, cell morphology, and cell growth status are similar to those of the original Colo205 cells. The ratio of its fluorescent signal with and without inhibitor treatment is the largest among all cell lines, and the ratio can reach 4-5 times when inhibited at 4 hours, which is completely suitable for the subsequent screening of Wnt inhibitors.

[0341] Experimental Example 2: Detection of the inhibitory ability of compounds on the Colo205-LUC-TCF / LEF-M1 reporter cell line. The Colo205-LUC-TCF / LEF-M1 cell line is a reporter tool cell stably transfected with the pGL4.49-LUC2-TCF / LEF vector, and its β-catenin Wnt pathway is continuously activated. After the addition of the inhibitor, the Wnt pathway is inhibited, and the expression level of firefly luciferase regulated by the TCF / LEF cis-element on the vector decreases. After the subsequent addition of the detection substrate, the detected light signal decreases accordingly, thereby detecting the inhibitory effect of the compound.

[0342] Add 100uL of the compound with a maximum concentration of 20uM to each well of a 96-well cell culture plate, and dilute the compound concentration by 3 times. Then inoculate 10,000 colo205 cells stably transfected with the reporter gene and 100uL of culture medium into each well, and make corresponding positive and negative control wells at the same time. Place the cells in a 5% CO2 cell culture incubator and culture at 37°C for 4h. After 4 hours, remove the culture medium, add 100uL of the reagent (Promega) containing the corresponding firefly luciferase substrate to each well, and measure the activity of the luciferase reporter gene. Use SpectraMax to read the luminescence intensity in full wavelength mode. The light signal intensity of cells treated only with DMSO is the positive control, and the light signal intensity of the cell-free well is the negative control. Calculate the IC50 concentration of each compound. The Colo 205 reporter gene detection data are summarized in Table 1.

[0345] Experimental Example 3: Proliferation inhibition test of compounds on Wnt mutant cell lines (Colo205, H929, HepG2 and DU4475) and non-Wnt mutant cell lines (RKO)

[0346] The cell lines used in the experiment are Colo205, H929, HepG2 and DU4475 cell lines in which the Wnt pathway is continuously activated and whose proliferation is Wnt pathway-dependent; and the RKO cell line in which the Wnt pathway is not activated under normal circumstances and whose proliferation is not dependent on the Wnt pathway is used as a control cell line to determine whether the inhibitory effect of the compounds of the present invention on Wnt-dependent proliferation is caused by other non-specific toxicity.

[0347] Colo205, H929, DU4475, HepG2 and RKO cell lines cultured in their respective culture media were treated during the logarithmic growth phase, and the cells were collected and prepared into a uniform cell suspension of known concentration, and then the cell suspension was added to a 96-well cell culture plate so that each well contained 1000-4000 cells. Place in a 5% CO2 cell culture incubator and culture at 37°C for 20-24 hours. On the second day, a completely dissolved, 3-fold gradient dilution of the compound was added to each cell culture well so that the final maximum concentration in the cell culture well was 10uM, and the culture was continued for 96 hours. This experiment uses Promega's cell activity detection test for detection. The more cells proliferate, the stronger the final signal intensity. The detection instrument is SpectraMax, full wavelength mode. The wells with only DMSO added were used as positive control wells, and the wells without cells were used as negative control wells. The IC50 value of each compound for the proliferation inhibition of cells with sustained Wnt activation or proliferation dependence, as well as the IC50 value for the proliferation inhibition of cells with inactivated Wnt or proliferation-independent Wnt were calculated to evaluate the inhibitory effect of the compound on the Wnt pathway and the toxic effect on normal cells (Table 2).
