Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of medicinal chemistry, and more specifically to NMT inhibitors having a structure represented by formula (1), methods for preparing the same, and the use of such compounds in the preparation of pharmaceutical compositions for treating, modulating and / or preventing NMT-mediated diseases. [Background technology]
[0002] NMT (N-myristoyltransferase) is an enzyme that can catalyze the myristoylation of over 100 proteins in human cells and influences downstream related signaling pathways. In humans, protein myristoylation is mediated by two widely expressed N-myristoyltransferases, NMT1 and NMT2. Myristoylation is a translation-coupled and post-translational modification reaction in eukaryotes, transferring a myristoyl group to the N-terminal glycine of a substrate protein via the action of NMT1 and NMT2 [Cell Death and Disease, 2018, 9(12):1143]. By functioning like a "switch," it can trigger a variety of reversible protein-cell membrane and protein-protein interactions.
[0003] NMT1 is highly expressed in various tumor tissues, and in liver cancer, NMT1 is associated with a poor prognosis, with patients with high NMT1 expression having shorter survival rates compared to patients with low expression. NMT1 expression has significant clinical implications; a study of primary breast cancer tissue and peritumoral tissue in 20 breast cancer patients showed that NMT1 expression was significantly elevated in breast cancer tissue compared to peritumoral tissue, and particularly significantly elevated in triple-negative breast cancer tissue [Cell Death and Disease, 2018, 9(12):1143]. Elevated NMT1 is associated with tumor development and relatively short survival times in patients. In patients with colorectal cancer, NMT1 is highly expressed in peripheral blood and bone marrow and can be used as a diagnostic marker for colorectal cancer [J TranslMed. 2007, 5:58]. High expression of NMT1 is associated with a poor prognosis in ovarian cancer and the progression of liver cancer and brain tumors, etc. [Annals of medicine, 2023, 55(1):1422-1430].
[0004] NMT1 catalyzes its substrate proteins to form myristoylated proteins, activating downstream signaling pathways such as NF-KB, C-Myc, and ERK, thereby promoting tumor cell proliferation, migration, and metastasis. Inhibition of NMT1 can induce cell cycle arrest, inhibit cell proliferation, and malignant growth [Annals of Medicine, 2023, 55(1):1422-1430]. NMT1 is highly expressed in various tumors and is associated with tumor staging, prognosis, and survival, making it a potential target point for oncological precision therapy. NMT inhibitors can significantly inhibit the activity of hematological malignancy cells, including B lymphocytes, inhibit myristoylation of lymphoma cells, and inhibit B cell receptor signaling, thereby inducing cell death and inhibiting tumor growth in mouse tumor models [Nature Communications, 2020, 11(1):5348].
[0005] Although several NMT small molecule inhibitors have been disclosed, the development of new compounds with better activity and pharmacokinetics is still required. The NMT inhibitor compound having the structure shown in the general formula (1) of the present invention exhibits excellent effects and actions, and provides a new option for the precise treatment of tumors.

[0020] It should be understood that, within the scope of the present invention, new or preferred technical solutions can be constructed by combining the above-described technical features of the present invention with the technical features specifically described below (e.g., in the examples). Due to space limitations, this will not be repeated here. [Modes for carrying out the invention]

The compounds of the present invention exhibit excellent inhibitory activity against the NMT1 enzyme and simultaneously possess good cell proliferation inhibitory activity against the MV-4-11 cell line, and based on this, the present invention has been completed.
[0022] Compounds of the present invention and their synthesis The present invention provides an inhibitor targeting NMT, that is, a compound of formula (1), or each isomer, crystalline form, pharmaceutically acceptable salt (inorganic salt or organic salt), hydrate or solvate thereof. Preferably, the compound of the present invention is as described in the first aspect.
[0023] The present invention further provides a method for preparing the compound of formula (1) of the present invention. Hereinafter, the method for preparing the compound of general formula (1) of the present invention will be specifically described, but these specific methods do not limit the present invention.
[0024] On the other hand, the compounds described in this specification follow methods well-known in the art. However, the conditions of the methods such as reactants, solvents, bases, amounts of compounds used, reaction temperature, time required for the reaction, etc. are not limited to the following description. The compound of the present invention can also be easily prepared by arbitrarily combining various synthesis methods described in this specification or known in the art, and such combinations can be easily carried out by those skilled in the art. On the other hand, the present invention further provides a method for preparing the compound represented by the general formula (1), which is prepared using the following general reaction process 1.
[0025] General reaction process 1:
Chemical formula
[0026] Embodiments of the compound of general formula (1) can be prepared according to general reaction process 1:, where Z is halogen, Q is boric acid or borate ester, M is halogen, OMs, OTos, etc., and R 1 , R 2 , R 3 , R 4 , R 5 , X 1 , X 2 , L, W, Y and n are as defined herein.
[0027] Related Definitions Unless otherwise specified, the following terms and phrases used herein shall have the meanings set forth below. No particular term or phrase should be construed as ambiguous or unclear unless specifically defined, and should be understood according to its ordinary meaning. Where a trade name is used herein, it refers to the corresponding product or its active ingredient.
[0028] As used herein, the term “pharmaceutically acceptable” means those compounds, materials, compositions and / or dosage forms that are suitable for use in contact with human and animal tissues without causing excessive toxicity, irritation, hypersensitivity reactions or other problems or complications commensurate with a reasonable benefit-risk ratio, within the bounds of sound medical judgment.
[0029] The term "pharmaceutically acceptable salt" refers to a salt of the compound of the present invention prepared with a compound having a specific substituent discovered in the present invention and a relatively non-toxic acid or base. If the compound of the present invention contains a relatively acidic functional group, a base addition salt can be obtained by contacting such compound with a sufficient amount of base in a pure solution or a suitable inert solvent. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amine, or magnesium salts or similar salts. If the compound of the present invention contains a relatively basic functional group, an acid addition salt can be obtained by contacting such compound with a sufficient amount of acid in a pure solution or a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include inorganic and organic acid salts, wherein the inorganic acids include hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, bisulfate, hydroiodic acid, and phosphorous acid, and the organic acids include acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, transbutenic acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-toluenesulfonic acid, citric acid, tartaric acid, and methanesulfonic acid, and further include salts of amino acids (e.g., arginine) and salts of organic acids such as glucuronic acid. Certain compounds of the present invention contain basic and acidic functional groups, thereby allowing them to be converted into either a base addition salt or an acid addition salt.
[0030] The pharmaceutically acceptable salts of the present invention can be synthesized from parent compounds containing an acidic or basic group by conventional chemical methods. Generally, such salts are prepared by reacting these compounds in free acidic or basic form with a chemically measured appropriate base or acid in water, an organic solvent, or a mixture thereof.
[0031] The compounds of the present invention may exist in the form of specific geometric isomers or stereoisomers. The present invention includes all such compounds, including cis and trans isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, and their racemic compounds and other mixtures (e.g., mixtures in which enantiomers and diastereomers are concentrated), and all of these mixtures are within the scope of the present invention. Substituents such as alkyl groups may have additional chiral carbon atoms. All of these isomers and mixtures thereof are within the scope of the present invention.
[0032] Unless otherwise specified, the terms "enantiomer" or "optical isomer" refer to stereoisomers that are mirror images of each other.
[0033] Unless otherwise specified, the terms "cis-trans isomer" or "geometric isomer" derive from the fact that the double bond or the single bond of the ring carbon atom cannot rotate freely.
[0034] Unless otherwise specified, the term "diastereomer" refers to stereoisomers in which a molecule has two or more chiral centers and there is no enantiomer relationship between the molecules.
[0035] Unless otherwise specified, "(D)" or "(+)" indicates dextrorotatory, "(L)" or "(-)" indicates levorotatory, and "(DL)" or "(±)" indicates racemic.
[0036] TIFF2026522099000006.tif51169
[0037] Unless otherwise specified, the terms "isomer excess" or "enantiomer excess" refer to the difference in the relative proportions of two isomers or two enantiomers. For example, if one isomer or enantiomer is present at 90% and the other isomer or enantiomer is present at 10%, the isomer or enantiomer excess (ee value) is 80%.
[0038] Optically active (R)- and (S)-isomers, as well as D and L isomers, can be prepared by chiral synthesis, chiral reagents, or other prior art. If one enantiomer of a compound of the present invention is desired, it can be prepared by asymmetric synthesis or derivatization containing a chiral auxiliary, where the resulting diastereomer mixture is separated and the auxiliary groups are cleaved to obtain the pure desired enantiomer. Alternatively, if the molecule contains a basic functional group (e.g., amino) or an acidic functional group (e.g., carboxyl group), a diastereomer salt is formed with a suitable optically active acid or base, and the diastereomer is then divided by a conventional method known in the art and recovered to obtain the pure enantiomer. Furthermore, the separation of enantiomers and diastereomers is usually achieved using chromatography, which uses a chiral stationary phase and is optionally combined with chemical derivatization (e.g., forming a carbamate from an amine).
[0039] The compounds of the present invention may contain an unusual proportion of atomic isotopes in one or more atoms constituting the compound. For example, tritium ( 3 H), Iodine-125( 125 I) or C-14 ( 14 Compounds can be labeled with radioactive isotopes such as C). For example, deuterated compounds can be formed by substituting a hydrogen atom with deuterium. The bond between deuterium and carbon is stronger than the bond between hydrogen and carbon, and deuterated drugs generally have advantages over non-deuterated drugs, such as reduced toxic side effects, increased drug stability, enhanced therapeutic effects, and extended in vivo half-life. All transformations of the compounds of the present invention, whether radioactive or otherwise, are included within the scope of the present invention.
[0040] "Optional" or "at your discretion" means that the events or situations described below may occur, but are not necessarily required to occur, and such descriptions include situations in which such events or situations occur, as well as situations in which such events or situations do not occur.
[0041] The term "substituted" refers to the replacement of any one or more hydrogen atoms on a particular atom by a substituent, which can include deuterium and variants of hydrogen as long as the valence of the particular atom is a normal valence and the compound after substitution is stable. When the substituent is oxygen (i.e., =O), it refers to the replacement of two hydrogen atoms. Oxygen substitution does not occur on an aromatic group. The term "optionally substituted" means that it may or may not be substituted, and unless otherwise specified, the type and number of substituents can be arbitrary based on chemical feasibility.
[0042] If any variable (e.g., R) appears one or more times in the composition or structure of a compound, its definition is independent for each appearance. Thus, for example, if a group is substituted by 0 to 2 R's, the group can be optionally substituted by up to two R's, and R in each situation has all independent options. Further, combinations of substituents and / or their variants are only permitted in situations where such combinations result in stable compounds.
[0043] When the number of one linking group is 0, such as -(CH2)0-, the linking group is a single bond.
[0044] When one of the variables is selected from a chemical bond, it indicates that the two groups it connects are directly linked. For example, in X-L-Y, if L represents a chemical bond, it represents that the structure is actually X-Y.
[0045] Unless otherwise specified, C n-n+m or C n -C n+m includes any specific situation of from n to n + m carbon atoms. For example, C 1-12 includes C1, C2, C3, C4, C5, C6, C7, C8, C9, C 10 , C 11 and C 12 and also includes any range from n to n + m. For example, C 1-12 is C1-3 , C 1-6 , C 1-9 , C 3-6 , C 3-9 , C 3-12 , C 6-9 , C 6-12 and C 9-12 This includes, for example, n-membered to n+m-membered rings, and similarly, n-membered to n+m-membered rings mean that the number of atoms on the ring is from n to n+m. For example, 3-12 membered rings include 3-membered rings, 4-membered rings, 5-membered rings, 6-membered rings, 7-membered rings, 8-membered rings, 9-membered rings, 10-membered rings, 11-membered rings and 12-membered rings, and also include any range from n to n+m. For example, 3-12 membered rings include 3-6 membered rings, 3-9 membered rings, 5-6 membered rings, 5-7 membered rings, 6-7 rings, 6-8 membered rings and 6-10 membered rings, etc.

[0134] Example 37: Screening for NMT1 enzyme catalytic inhibitory activity This study evaluates the ability of the compound of the present invention to inhibit NMT1 catalytic activity in vitro. The experiment characterizes the NMT1 inhibitor under 1.25 μM myristoyCoA (lithium myristoyl coenzyme A salt, sigma, M4414) using FI fluorescence intensity analysis. In this experiment, the polypeptide HSPP60SRC (Nanjing Peptide Co., Ltd., NJP23953) with the sequence H-Gly-Ser-Asn-Lys-Ser-Lys-Pro-Lys-NH2 is synthesized as the reaction substrate. The final concentration of NMT1 enzyme is 6 nM, the final concentration of CPM (reactive thiol fluorescent probe, invitrogen, D346) is 1 μM, the final concentration of HSPP60 SRC is 20 μM, and the final concentration of DMSO is 0.5%.
[0135] The compound is dissolved in DMSO to obtain a 10 mM stock solution. A dose gradient reaction solution is prepared to an endpoint compound concentration of 3 mM, and then diluted threefold with DMSO to obtain a total of 10 data points. Using an ECHO ultrasonic pipetting system (BECKMAN, ECHO 655 system), 0.05 μL of the diluted compound solution is transferred to a 384-well analysis plate (Corning, CLS4514), 2.5 μL of NMT1 enzyme working solution is added to the 384-well analysis plate, and incubated at 25°C for 10 minutes. Then 5 μL of CPM and myristoy COA working solution is added, and the mixture is centrifuged at 1000 rpm for 1 minute. Subsequently, 2.5 μL of HSPP60 SRC working solution is added to allow the reaction to proceed, and the reaction is incubated at 25°C for 45 minutes. The FI signal (em: 320 nm, ex: 405 nm) is detected using the HTS high-throughput drug screening multifunctional microplate reader (BMG, PHERA star FSX).
[0136] The inhibition rate of compounds against NMT1 enzyme catalytic activity was calculated using the following formula: Inhibition rate (%) = 100 × (Average value of DMSO group - Average value of compound) / (Average value of DMSO group - Average value of blank control group). Furthermore, the IC of compounds was calculated based on a nonlinear regression equation using the software XLfit 5.5.0. 50 The curve is fitted. Table 1 shows the inhibitory activity of the compounds of the present invention against the NMT1 enzyme catalyst.
[0137] Example 38: Screening of compounds for MV-4-11 cell antiproliferative activity This study analyzes the cytotoxicity of MV-4-11 human myeloid monocytic leukemia cells after 3 days of treatment with an NMT1 inhibitor using cell proliferation experiments. The MV-4-11 cell line was purchased from Nanjing CoBioer Biotechnology Co., Ltd. and cultured in IMDM medium (Viva cell) in a cell incubator (Thermo) at 37°C with 5% carbon dioxide. In this experiment, the NMT1 inhibitor was dissolved in DMSO to obtain a 600 μM stock solution. A dose gradient reaction solution was prepared until the endpoint compound concentration reached 3 μM, and then diluted threefold with DMSO to obtain a total of eight data points. The final concentration of DMSO was 0.5%.
[0138] Seed MV-4-11 cells in a white 96-well plate and prepared an 80 μL cell suspension containing 6000 MV-4-11 cells per well. The cell plate was incubated overnight in a carbon dioxide incubator, then 20 μL of different concentrations of NMT1 inhibitor solution were added to each well plate, and the 96-well plate was incubated for 3 days. Another cell plate was prepared, and the signal value on the day of drug addition was read as the maximum value (Max value in the following formula), and the data was analyzed. 25 μL of cell viability chemiluminescence detection reagent was added to each well of this cell plate and incubated at room temperature for 10 minutes to stabilize the luminescence signal. The readings were obtained using a multi-label analyzer.
[0139] The raw data is converted to an inhibition rate using the formula (Sample-Min) / (Max-Min)×100%, and the IC 50 The values are obtained by curve fitting using four parameters (obtained using the "log(inhibitor) vs.response - Variable slope" mode in GraphPad Prism). Min: 0.5% DMSO-treated cell wells, Max: Day 0 wells. Table 1 shows the inhibitory activity of the compounds of the present invention against MV-4-11 cell proliferation. [Table 1]
[0140] As can be seen from the data in the table above, the compounds of the present invention have very strong inhibitory activity against NMT1 enzyme catalysts, and at the same time, the compounds also have very strong antiproliferative activity against MV-4-11 cells. In particular, compounds 21, 27, 29, 30, 31, 32, 34 and 36 have very strong inhibitory activity against NMT1 enzyme catalysts and very strong antiproliferative activity against MV-4-11 cells, and the inhibitory activity against NMT1 enzyme catalysts IC 50 It is less than 2 nM and has antiproliferative activity against MV-4-11 cells IC 50 It is less than 10 nM.
