Description

A class of phosphoenol compounds, preparation methods thereof, and applications thereof in treating inflammatory diseases of the body Technical Field

[0001] The present invention relates to the field of biological therapy, and in particular to a class of phosphoenol compounds, a preparation method thereof, and an application thereof in treating inflammatory diseases of the body. Background Art

[0002] In recent years, the number of patients with inflammatory diseases related to the immune system has been increasing, including psoriasis, multiple sclerosis, ankylosing spondylitis, inflammatory bowel disease, systemic lupus erythematosus, and asthma. Numerous researchers have devoted their efforts to synthesizing and identifying small molecule drugs that can effectively treat these diseases. However, few small molecules have been successfully developed as clinically effective therapies, making the treatment of inflammatory diseases a pressing challenge. The study of inflammatory diseases is inseparable from the understanding of the immune system. Given the rapid activation and proliferation of immune cells upon encountering foreign or self-antigens, the exploration of their cellular metabolism has become a major research hotspot. Researchers have used the effects of cellular metabolism regulators on T cells to elucidate how molecular glues such as pyruvate kinase (PKM2) promote the tight binding of PKM2 monomers within cells, forming multimers, thereby influencing T cell differentiation and further regulating immune responses. Other studies have attempted to demonstrate therapeutic efficacy by blocking cellular metabolism in mouse tumor models. However, these small molecule compounds have yet to become clinically effective. Furthermore, the inhibitory effects of these existing compounds on cancer cell proliferation and their ability to kill cancer cells contradict the goal of treating inflammatory diseases.

[0003] Currently, no researchers have developed new compounds and their compositions as regulators of cellular metabolism to study their functions and therapeutic effects in autoimmune and inflammatory diseases. Summary of the Invention

[0081] The stereochemical definitions and conventions used herein generally follow those of SP 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.

[0082] Many organic compounds exist in optically active forms, meaning they have the ability to rotate the plane of plane-polarized light. When describing an optically active compound, the prefixes D and L or R and S are used to indicate the absolute configuration of the molecule about its chiral center(s). The prefixes d and l or (+) and (-) are the symbols used to designate the rotation of plane-polarized light caused by the compound, where (-) or l indicates that the compound is left-handed. A compound prefixed with (+) or d is right-handed. A specific stereoisomer is an enantiomer, and a mixture of such isomers is called an enantiomeric mixture. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which can occur when there is no stereoselectivity or stereospecificity in a chemical reaction or process.

[0083] Any asymmetric atom (e.g., carbon, etc.) of the compounds disclosed herein can exist in a racemic or enantiomerically enriched form, such as in the (R)-, (S)-, or (R,S)-configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in terms of the (R)- or (S)-configuration.

[0084] Depending on the choice of starting materials and process, the compounds of the present invention may exist as one of the possible isomers or a mixture thereof, such as a racemate or a mixture of diastereoisomers (depending on the number of asymmetric carbon atoms). Optically active (R)- or (S)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the cycloalkyl substituents may be in the cis or trans configuration.

[0085] Any resulting mixture of stereoisomers can be separated into the pure or substantially pure geometric isomers, enantiomers, and diastereomers on the basis of the differences in the constituent physicochemical properties, for example, by chromatography and / or fractional crystallization.

[0086] Any racemate of the resulting final product or intermediate can be separated into its optical antipodes by methods familiar to those skilled in the art using known methods, such as by separating the diastereomeric salts obtained. The racemic products can also be separated by chiral chromatography, such as high performance liquid chromatography (HPLC) using a chiral adsorbent. In particular, enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Principles of Asymmetric Synthesis (2 nd Ed.Robert E.Gawley, Jeffrey Aubé, Elsevier, Oxford, UK, 2012); Eliel, ELStereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); Wilen, SHTables of Resolving Agents and Optical Resolutions p.268 (ELEliel, Ed., Univ. of Notre Dame Press, Notre Dame, IN 1972); Chiral Separation Techniques: A Practical Approach (Subramanian, G.Ed., Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, Germany, 2007).

[0087] The term "tautomer" or "tautomeric form" refers to structural isomers with different energies that can be converted into each other through a low energy barrier. If tautomerism is possible (such as in solution), a chemical equilibrium of the tautomers can be reached. For example, proton tautomers (also known as prototropic tautomers) include interconversions performed by proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers include interconversions performed by the reorganization of some bonding electrons. A specific example of keto-enol tautomerism is the interconversion of pentane-2,4-dione and 4-hydroxypent-3-ene-2-one tautomers. Another example of tautomerism is phenol-keto tautomerism. A specific example of phenol-keto tautomerism is the interconversion of pyridine-4-ol and pyridine-4(1H)-one tautomers. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.

[0088] The term "prodrug" as used in the present invention refers to a compound that is converted into a compound represented by formula (I) in vivo. Such conversion is affected by the hydrolysis of the prodrug in the blood or by enzyme conversion to the parent structure in the blood or tissue. The prodrug compound of the present invention can be an ester. In the existing invention, esters that can be used as prodrugs include phenyl esters, aliphatic (C 1-24) esters, acyloxymethyl esters, carbonates, carbamates, and amino acid esters. For example, a compound of the present invention containing a hydroxyl group can be acylated to produce a prodrug form of the compound. Other prodrug forms include phosphate esters, such as these phosphate ester compounds, which are obtained by phosphorylating a hydroxyl group on the parent compound. For a complete discussion of prodrugs, see T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the ACSSymposium Series, Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987, J. Rautio et al., Prodrugs: Design and Clinical Applications, Nature Review Drug Discovery, 2008, 7, 255-270, and SJ Hecker et al., Prodrugs of Phosphates and Phosphonates, Journal of Medicinal Chemistry, 2008, 51, 2328-2345.

[0089] "Metabolite" refers to a product resulting from the in vivo metabolism of a specific compound or salt thereof. Metabolites of a compound can be identified using techniques known in the art, and their activity can be characterized using assays such as those described herein. Such products can be obtained by administering the compound through oxidation, reduction, hydrolysis, amidation, deamidation, esterification, defatting, enzymatic cleavage, and the like. Accordingly, the present invention encompasses metabolites of the compound, including metabolites produced by contacting a compound of the invention with a mammal for a sufficient period of time.

[0090] As used herein, "pharmaceutically acceptable salts" refer to organic and inorganic salts of the compounds of the present invention. Pharmaceutically acceptable salts are well known in the art, as described in S.M. Berge et al., "Describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66: 1-19." Pharmaceutically acceptable salts formed from non-toxic acids include, but are not limited to, inorganic acid salts formed by reaction with amino groups, such as hydrochlorides, hydrobromides, phosphates, sulfates, and perchlorates, and organic acid salts such as acetates, oxalates, maleates, tartrates, citrates, succinates, and malonates, or salts obtained by other methods described in the literature, such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, cyclopentylpropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, propionate, stearate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N + (C 1-4 The present invention also contemplates quaternary ammonium salts formed by any compound containing a N group. Water-soluble or oil-soluble or dispersible products can be obtained by quaternization. Alkali metal or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Pharmaceutically acceptable salts further include appropriate, non-toxic ammonium, quaternary ammonium salts and amine cations formed by counter ions, such as halides, hydroxides, carboxylates, sulfates, phosphates, nitrates, C 1-8 Sulfonates and aromatic sulfonates.

[0091] Pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound containing alkaline or acidic moieties by conventional chemical methods. Usually, this salt can be prepared by reacting the free acid or alkaline form of these compounds with stoichiometric appropriate alkali or acid in water or an organic solvent or a mixture thereof.

[0092] As used herein, a "solvate" refers to an association formed between one or more solvent molecules and a compound of the present invention. Solvents that form solvates include, but are not limited to, water, isopropanol, ethanol, methanol, dimethyl sulfoxide, ethyl acetate, acetic acid, and aminoethanol. The term "hydrate" refers to an association formed when the solvent molecule is water.

[0093] As used herein, "inflammatory disease" refers to any disease, disorder, or condition characterized by excessive inflammatory symptoms, host tissue damage, or loss of tissue function resulting from an excessive or uncontrolled inflammatory response. "Inflammatory disease" also refers to a pathological state mediated by leukocyte influx and / or neutrophil chemotaxis.

[0094] As used herein, "inflammation" refers to a local protective response caused by tissue damage or destruction, which serves to destroy, dilute, or isolate (isolate) harmful substances and damaged tissue. Inflammation is significantly associated with leukocyte influx and / or neutrophil chemotaxis. Inflammation can result from infection with pathogenic organisms and viruses, as well as non-infectious causes such as trauma or reperfusion following myocardial infarction or stroke, immune responses to foreign antigens, and autoimmune responses. Therefore, inflammatory diseases that can be treated with the compounds disclosed herein include diseases associated with specific defense system responses as well as non-specific defense system responses.

[0134] Certain compounds of the present invention may be used therapeutically in free form or, if appropriate, in the form of pharmaceutically acceptable derivatives thereof. Non-limiting examples of pharmaceutically acceptable derivatives include pharmaceutically acceptable prodrugs, salts, esters, salts of such esters, or any other adducts or derivatives that, when administered to a patient in need thereof, directly or indirectly provide a compound of the present invention or a metabolite or residue thereof.

[0135] The pharmaceutical composition disclosed in the present invention can be prepared and packaged as bulk form, wherein a safe and effective amount of the compound shown in formula (I) can be extracted and then administered to the patient in the form of a powder or syrup. Alternatively, the pharmaceutical composition disclosed in the present invention can be prepared and packaged as a unit dosage form, wherein each physically discrete unit contains a safe and effective amount of the compound shown in formula (I). When prepared in unit dosage form, the pharmaceutical composition disclosed in the present invention can generally contain, for example, 0.5 mg to 1 g or 1 mg to 700 mg or 5 mg to 100 mg of the compound disclosed in the present invention.

[0136] As used herein, "pharmaceutically acceptable excipient" means a pharmaceutically acceptable material, mixture, or vehicle that contributes to the consistency of a dosage form or pharmaceutical composition. Each excipient, when combined, must be compatible with the other ingredients of the pharmaceutical composition to avoid interactions that could significantly reduce the efficacy of the disclosed compounds upon administration to a patient and interactions that could render the pharmaceutical composition unpharmaceutically acceptable. Furthermore, each excipient must be pharmaceutically acceptable, e.g., possess a sufficiently high degree of purity.

[0137] Suitable pharmaceutically acceptable excipients will vary depending on the specific dosage form selected. In addition, pharmaceutically acceptable excipients may be selected based on their specific function in the composition. For example, certain pharmaceutically acceptable excipients may be selected to facilitate the production of a uniform dosage form. Certain pharmaceutically acceptable excipients may be selected to facilitate the production of a stable dosage form. Certain pharmaceutically acceptable excipients may be selected to facilitate the transport or transportation of the disclosed compounds from one organ or part of the body to another organ or part of the body when administered to a patient. Certain pharmaceutically acceptable excipients may be selected to enhance patient compliance.

[0138] Suitable pharmaceutically acceptable excipients include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants, glidants, granulating agents, coating agents, wetting agents, solvents, cosolvents, suspending agents, emulsifiers, sweeteners, flavoring agents, taste masking agents, coloring agents, anti-caking agents, humectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants and buffers. It will be appreciated by those skilled in the art that certain pharmaceutically acceptable excipients may provide more than one function and may provide alternative functions, depending on how much of the excipient is present in the formulation and which other excipients are present in the formulation.

[0139] The skilled person has the knowledge and skill to master this area, so that they can select the suitable pharmaceutically acceptable excipient of appropriate amount for the present invention.In addition, there are a large number of resources available to the skilled person, and they describe pharmaceutically acceptable excipients, and are used to select suitable pharmaceutically acceptable excipients.Examples include Remington's Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press).

[0140] Various carriers for configuring pharmaceutically acceptable compositions and known techniques for their preparation are disclosed in Remington: The Science and Practice of Pharmacy, 21st edition, 2005, ed. D. B. Troy, Lippincott Williams & Wilkins, Philadelphia, and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, the contents of each of which are incorporated herein by reference. Except for any conventional carriers that are incompatible with the disclosed compounds of the present invention, such as those that may produce any undesirable biological effects or that may interact in a deleterious manner with any other ingredient in the pharmaceutically acceptable composition, it is contemplated that their use is within the scope of the present invention.

[0141] The pharmaceutical compositions disclosed herein are prepared using techniques and methods known to those skilled in the art. A description of some common methods in the art can be found in Remington's Pharmaceutical Sciences (Mack Publishing Company).

[0142] Thus, in another aspect, the present invention relates to a process for preparing a pharmaceutical composition comprising a compound disclosed herein and a pharmaceutically acceptable excipient, vehicle, carrier, or combination thereof, the process comprising mixing the ingredients.

[0145] The pharmaceutical compositions provided herein can be provided as compressed tablets, tablets, chewable lozenges, fast-dissolving tablets, composite compressed tablets, or enteric-coated, sugar-coated, or film-coated tablets. Enteric-coated tablets are compressed tablets coated with a substance that resists the effects of gastric acid but dissolves or disintegrates in the intestines, thereby protecting the active ingredients from the acidic environment of the stomach. Enteric coatings include, but are not limited to, fatty acids, fats, phenyl salicylate, waxes, shellac, ammoniated shellac, and cellulose acetate phthalate. Sugar-coated tablets are compressed tablets surrounded by a sugar coating, which helps mask unpleasant tastes or odors and prevents tablet oxidation. Film-coated tablets are compressed tablets covered with a thin layer or film of a water-soluble substance. Film coatings include, but are not limited to, hydroxyethylcellulose, sodium carboxymethylcellulose, polyethylene glycol 4000, and cellulose acetate phthalate. Film coatings impart the same general properties as sugar coatings. Composite compressed tablets are compressed tablets produced through more than one compression cycle, including multilayer tablets and press-coated or dry-coated tablets.

[0146] Tablet dosage forms can be prepared from the active ingredient in powder, crystal or granular form alone or in combination with one or more carriers or excipients described herein, including binders, disintegrants, controlled release polymers, lubricants, diluents and / or colorants. Flavoring agents and sweeteners are particularly useful in forming chewable tablets and lozenges.

[0147] The pharmaceutical composition provided by the present invention can be provided in soft capsules or hard capsules, which can be prepared from gelatin, methylcellulose, starch or calcium alginate. The hard gelatin capsule, also known as dry-filled capsule (DFC), consists of two sections, one section inserted into the other, thus completely encapsulating the active ingredient. Soft elastic capsules (SEC) are soft, spherical shells, such as gelatin shells, which are plasticized by adding glycerol, sorbitol or similar polyols. The soft gelatin shells can contain preservatives to prevent microbial growth. Suitable preservatives are those as described in the present invention, including methylparaben and propylparaben, and sorbic acid. The liquid, semisolid and solid dosage forms provided by the present invention can be encapsulated in capsules. Suitable liquid and semisolid dosage forms include solutions and suspensions in propylene carbonate, vegetable oils or triglycerides. Capsules containing such solutions can be prepared as described in U.S. Pat. Nos. 4,328,245; 4,409,239 and 4,410,545. The capsules may also be coated as known to those skilled in the art to improve or sustain dissolution of the active ingredient.

[0148] The pharmaceutical compositions provided herein can be provided in liquid and semisolid dosage forms, including emulsions, solutions, suspensions, elixirs, and syrups. Emulsions are two-phase systems in which one liquid is completely dispersed in another liquid in the form of small globules, which can be oil-in-water or water-in-oil. Emulsions can include pharmaceutically acceptable non-aqueous liquids and solvents, emulsifiers, and preservatives. Suspensions can include pharmaceutically acceptable suspending agents and preservatives. Aqueous alcoholic solutions can include pharmaceutically acceptable acetals, such as di(lower alkyl) acetals of lower alkyl aldehydes, such as acetaldehyde diethyl acetal; and water-soluble solvents having one or more hydroxyl groups, such as propylene glycol and ethanol. Elixirs are clear, sweet-tasting hydroalcoholic solutions. Syrups are concentrated aqueous solutions of sugars, such as sucrose, and can also contain preservatives. For liquid dosage forms, for example, solutions in polyethylene glycol can be diluted with a sufficient amount of a pharmaceutically acceptable liquid carrier, such as water, for accurate and convenient administration.

[0149] Other useful liquid and semisolid dosage forms include, but are not limited to, those comprising the active ingredient provided herein and a secondary mono- or poly-alkylene glycol, including 1,2-dimethoxymethane, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, polyethylene glycol-350-dimethyl ether, polyethylene glycol-550-dimethyl ether, polyethylene glycol-750-dimethyl ether, wherein 350, 550, and 750 refer to the approximate average molecular weight of the polyethylene glycol.

[0185] Biological experimental methods

[0186] The present invention is described below with reference to specific examples. It should be noted that these examples are merely illustrative and do not limit the present invention in any way.

[0187] Compound preparation route:

[0188] The first step of the reaction:

[0189] To a round-bottom flask containing 50 mL of tetrahydrofuran (THF) were added pyruvic acid A (5 mmol, 1.0 equivalent), alcohol B (10 mmol, 2.0 equivalent) and pyridine (12.5 mmol, 2.5 equivalent) in sequence, and the mixture was cooled to 0°C. Methanesulfonyl chloride (6 mmol, 1.2 equivalent) was then slowly added dropwise to the flask. The reaction temperature was then gradually raised to room temperature and stirred for 10 hours. 20 mL of water was added to the reaction flask to terminate the reaction. The resulting solution was extracted three times with 40 mL of ethyl acetate. The organic phases of the extractions were combined. After drying over anhydrous sodium sulfate, the organic solvent was removed under vacuum to obtain a crude product. Further purification by flash column chromatography afforded ester C.

[0190] Second step of reaction:

[0191] To a round-bottom flask containing 50 mL of anhydrous ether, add ester C (3 mmol, 1.0 equiv). Bromine (4.5 mmol, 1.5 equiv) is then slowly added dropwise to the solution at room temperature. The reaction is slowly heated to 50°C and refluxed for 4 hours. After completion of the reaction, the organic phase is washed twice with water and then with saturated sodium chloride solution. After drying over anhydrous sodium sulfate, the product is concentrated in vacuo and purified by flash column chromatography to afford bromopyruvate D.

[0192] Reaction step 3:

[0193] To a round-bottom flask containing 50 mL of tetrahydrofuran (THF) was added bromoacetonate D (2 mmol, 1.0 equiv). Triethylphosphine (2 mmol, 1.0 equiv) was then added dropwise at 0°C. The reaction was heated to 80°C and refluxed at that temperature for 2 hours. After completion of the reaction, the organic solvent was removed in vacuo to yield the crude product. Purification by flash column chromatography afforded compound 4 (Cpd 4).

[0194] Reaction step 4:

[0195] Cpd4 (1.0 equivalent) was added to a round-bottom flask containing 20 mL of dichloromethane (DCM). After the solution was cooled to 0°C, trimethylsilyl bromide (TMSBr, 10 equivalents) was slowly added dropwise to the reaction. The reaction was then stirred at room temperature for 4 hours. After the reaction was completed, 10 mL of water was added and stirred vigorously for 10 minutes to promote the dissolution of the product 5 in the aqueous phase. The aqueous phase was washed twice with dichloromethane and then concentrated under vacuum to obtain Cpd 5.

Count the cells in 1 mL of cell suspension, adjust the cell suspension concentration to 2×10^6 cells / mL, add cytokines for differentiation into Th17 or Tc17 (IL6 working concentration is 20 ng / mL, TGFβ working concentration is 1 ng / mL), cytokines for differentiation into Th2 (IL4 working concentration is 100 ng / mL, anti-IFNγ working concentration is 5 μg / mL), cytokines for differentiation into Th1 (IL2 working concentration is 20 ng / mL, IL12 working concentration is 10 ng / mL), and cytokines for differentiation into Treg (TGFβ working concentration is 1 ng / mL), and add 50 μg / mL of peptide MOG35-55 (2D2 genotype mice) or 0.5 μg / mL of peptide OVA257-264 (OT-I genotype mice) and mix well to obtain the phosphoenolase cell fluid to be tested.

[0243] (5) When using C57BL / 6 wild-type mice for in vitro culture, it is necessary to coat the cell culture plates with antibodies in advance: dilute anti-CD3 and anti-CD28 in PBS at a working concentration of 5 μg / mL the night before the experiment, and add the dilution to a 96-well plate at 100 μL / well; seal the 96-well plate with sealing film and place it in a 4°C refrigerator, away from light, overnight.

[0244] (6) Childish Isolation of CD4-positive T cells. 8-12 week-old C57BL / 6 wild-type mice housed in an SPF animal care facility were euthanized. The spleen and peripheral lymph nodes were isolated using sterile surgical instruments in a cleanroom. The cells were then placed through a 70 μM filter placed on a 50 mL tube. The tissue was thoroughly triturated using the handle of a 1 mL syringe. All cells on the filter were rinsed into the 50 mL tube with staining buffer and centrifuged at 500 g for 5 minutes. The supernatant was discarded, and 8 mL / mouse of red blood cell lysis buffer was added to the tube to resuspend the cells. After incubation at room temperature for 5 minutes, an equal volume of staining buffer was added and mixed to terminate lysis. The supernatant was then centrifuged at 500 g and the supernatant discarded. The cells were resuspended in 0.5 mL of staining buffer and filtered through a 70 μM flow cytometer tube with a cap. 50 μL of CD4 (L3T4) Microbeads were then added and mixed. The tube was incubated at 4°C in the dark for 15 minutes. Add 4mL staining buffer to the flow tube, centrifuge at 500G and discard the supernatant, resuspend the cells with 1mL staining buffer / mouse, add to the LS column placed on the magnetic stand, wait for the liquid to drip clean, and then add staining buffer three times, 3mL / time. Remove the column, flush the cells into a 15mL tube with staining buffer, centrifuge and discard the supernatant. Dilute the flow cytometry antibodies CD4, CD44, CD62L and CD25 (500μL / mouse) with staining buffer at a ratio of 1:400, resuspend the cells with the antibody dilution solution, incubate at 4℃ in the dark for 30 minutes, and then wash the cells with staining buffer. After resuspending the cells with staining buffer, filter them into the tube using a 70μM flow tube with a cap, and finally sort the cells marked as CD4 positive, CD44 negative, CD62L positive and CD25 negative into the collection tube through a flow sorter to obtain naive cells. CD4-positive T cells.

[0245] (7) C57BL / 6 wild-type mice were selected from naive mice In vitro cell culture of CD4 positive T cells. CD4+ T cells were resuspended in T cell culture medium (concentration: 5 × 10^5 cells / mL), and cytokines for Th17 differentiation were added (IL6 working concentration: 20 ng / mL, TGFβ working concentration: 1 ng / mL, IL1β working concentration: 10 ng / mL, IL23 working concentration: 25 ng / mL), and mixed thoroughly. This gave a cell solution to be mixed with the phosphoenolase compound to be tested.

[0246] (8) Divide the cell suspension mixed with the phosphoenol compound to be tested in the previous step into several 1.5 mL EP tubes, 400 μL / tube. Dilute the test compound to 100 times the working concentration with T cell culture medium, then add it to the cell suspension and mix thoroughly. 400 μL of cell suspension requires 4 μL of 100X compound dilution. For the control group, add the same volume of the test phosphoenol compound to the corresponding T cell culture medium and mix thoroughly. Pipette the same volume of liquid as the 100X compound dilution into the cell suspension. After mixing the liquid in each 1.5 mL EP tube, add it to the corresponding 96-well plate, 100 μL / well. Place in a 37°C cell culture incubator and culture for 48 hours or 96 hours.

[0247] (9) 48 hours (whole spleen cells of special genotype mice cultured in vitro) or 96 hours (selected naive spleen cells from C57BL / 6 wild-type mice) After in vitro cell culture of CD4-positive T cells), the cells were resuspended and transferred to a U-bottom 96-well plate, centrifuged at 500G to remove the supernatant, 100 μL T cell stimulation solution (GolgiStop, Ionomycin, PMA) was added to each well, and the cells were placed in a 37°C cell culture incubator for stimulation for 4 hours. The cell plate was removed and the cells were washed with staining buffer, centrifuged at 500G to remove the supernatant, and 50 μL surface antibody dilution solution was added to each well to perform flow cytometry staining on the cells (Live / Dead dilution ratio of 1:4000; according to the cell type, Th is CD25 and CD4; Tc is CD25 and CD8, dilution ratio 1:400), and placed in a 4°C refrigerator away from light for staining for 30 minutes. The cells were washed with buffer, centrifuged at 500G to remove the supernatant, fixed and punched with punching solution for 50 minutes or overnight, washed with 1xPerm, centrifuged at 800G to remove the supernatant, and 50 μL of cytokine (IL17A, IL17F, GM-CSF, IFNγ, IL4, dilution ratio 1:400) or transcription factor (RORγt, FoxP3, Phospho-STAT3, Phospho-STAT5 dilution ratio 1:200) antibody dilution solution was added to each well to stain the cells for 2 hours or overnight, and finally the experimental results were recorded by flow cytometry.

[0248] (10) The experimental results showed that the phosphoenol compound (administered group) could inhibit the secretion of cytokines IL17A, IL17F, GMCSF, and IFNγ by Th cells (Figure 1-A). The experimental results further showed that the acid enol compound (administered group) could significantly inhibit the expression of RORγt (Figure 1-B), but significantly increase the expression of transcription factor FoxP3 (Figure 1-C).

[0249] Test Example 2: Application of phosphoenol compounds in mouse autoimmune models

[0250] (1) Supplies: Supplies required for in vitro cell culture are as described in Example 1, including 24-well plates, BD brand 1 mL syringes, and common 1 mL syringes.

[0251] (2) Reagents: The reagents required for in vitro cell culture are as described in Example 1, including peptide MOG35-55, pertussis toxin, PBS, DMF, Tween 80, and anesthetic.

[0252] (3) The spleen cells of 2D2 genotype mice were induced to differentiate into Th17 in vitro (for detailed operation, see Example 1 above), and IL6, TGFβ, IL1β, IL23 and peptide MOG35-55 were added. The cell fluid was added to a 24-well plate at 500 μL / well and placed in a 37°C cell culture incubator. After 34 hours, 20 μM of the phosphoenol compound to be tested was added and incubated for another 14 hours. The cells were washed out and injected into RAG1 gene knockout mice through the tail vein using a BD brand 1 mL syringe at a rate of 1.5x10^6 cells per recipient mouse, 300 μL / mouse. 24 hours later, the mice were intraperitoneally injected with pertussis toxin using a regular 1 mL syringe, 300 ng of the solvent was PBS / mouse, 200 μL / mouse.

[0253] (4) Dosing of mice. PBS, DMF, and Tween80 were thoroughly mixed in a ratio of 88:10:2 and filtered through a 0.22 filter to obtain a PDT solvent. The phosphoenol compound to be tested was added to the PDT solvent at 250 μg / 200 μL; an equal amount of DMSO was added to the control group. The prepared drug was injected into the mouse via the peritoneal cavity at 200 μL / mouse. The drug was administered daily for 18 consecutive days. After 28 days, the popliteal lymph nodes of the mice were isolated and cell suspensions were prepared for flow cytometry analysis of Th17 cell-related characteristic molecules. 24 hours later, the phosphoenol compound to be tested was injected into the mouse peritoneal cavity using an ordinary 1 mL syringe. The dosage was 20 μL of drug per mouse per day (drug concentration was 50 mM) and the drug was administered for 18 consecutive times.

[0254] (5) Starting from the return of cells through the tail vein, the weight of the mice was recorded every day and the clinical disease scores of the mice were observed. Clinical disease scores: healthy state (0 points); weak tail (1 point); slow walking, uncoordinated movement of the left and right hind limbs, and involuntary tremors of the hind limbs (2 points); paralysis of the hind limbs alone (3 points); paralysis of both hind limbs (4 points); paralysis of the forelimbs, or death of the mouse (5 points). On the 28th day after the return of cells through the tail vein, the central nervous system (CNS) of the mice was removed and a single cell suspension was prepared. The proportion and number of cells contained in the suspension were analyzed using flow cytometry.

[0255] (6) The experimental results showed that the disease incidence score of autoimmune encephalomyelitis (EAE) in the drug group was significantly lower than that in the control group (Figure 2-A), and the weight loss in the drug group was also significantly lower than that in the control group (Figure 2-B). This shows that phosphoenol compounds can significantly delay the progression of autoimmune diseases in mice.
