Description

[Technical Field]

[0001] The present invention relates to the field of medicinal chemistry, and in particular to compounds having activity to activate 5'-adenosine monophosphate-activated protein kinase (AMPK), methods for their preparation, pharmaceutical compositions containing said compounds, and the use of these compounds in the manufacture of medicaments for reducing fatty acid synthesis, inhibiting triglyceride and cholesterol synthesis, preventing and / or treating obesity and type II diabetes, preventing and / or treating tumors, preventing and / or treating Parkinson's disease, preventing and / or treating Alzheimer's disease, or prolonging the lifespan of mammals. [Background technology]

[0002] 5'-Adenosine monophosphate-activated protein kinase (AMP-activated protein kinase, AMPK) is a key molecule in sensing energy levels and regulating metabolic homeostasis within cells and living organisms. AMPK is a heterotrimer consisting of three subunits, α, β, and γ. Under physiological conditions, AMPK is activated by its upstream kinases through phosphorylation, which initiates a series of downstream reactions, including promoting triglyceride hydrolysis in adipocytes, promoting the uptake and oxidation of blood fatty acids by the liver, inhibiting fatty acid and cholesterol synthesis and triglyceride formation, promoting lipid oxidation and glucose uptake and degradation in muscle, suppressing insulin secretion and glycogen synthesis in pancreatic islet β cells, inhibiting protein synthesis, and promoting autophagy and ketogenesis (Hardie DG, Ross FA, Hawley SA. Nat Rev Mol Cell Biol. 2012 13(4):251-62). As a result of these actions, AMPK increases energy-producing metabolism and decreases energy-consuming metabolism, thereby maintaining a steady state of energy and ensuring normal cellular activity. Therefore, activation of AMPK can exert many beneficial effects on health. For example, in many tumor tissues, such as melanoma, breast cancer, colon cancer, and lung cancer, AMPK expression or activity is strongly inhibited, further disrupting the natural balance between anabolic and catabolic metabolism in these tissues and promoting tumor development (Shackelford DB, Shaw RJ. Nat Rev Cancer. 2009(8):563-75). At the cellular level, AMPK activation suppresses the mTORC1 complex, thereby inhibiting the synthetic metabolism of tumor cells and inhibiting their proliferation (Inoki K, Kim J, Guan KL. Annu Rev Pharmacol Toxicol. 2012 52:381-400). Numerous studies have shown that AMPK activation also inhibits tumor cell proliferation, blocking tumor cell proliferation and causing apoptosis by promoting p53 activation (Jones RG et al., Mol Cell. 2005 18(3):283-93). Therefore, AMPK activators play an important role in tumor prevention and treatment.

[0003] In addition to tumors, AMPK is also closely related to diabetes. Significant inhibition of AMPK activity has been found in the peripheral tissues of obese mice and type 2 diabetic patients (Viollet B. et al., Crit Rev Biochem Mol Biol. 2010 45(4):276-95). Activation of AMPK promotes the translocation of the glucose transporter GLUT4 to the cell membrane in muscle, increasing the absorption and catabolism of blood glucose by muscle, thereby lowering blood glucose (Huang S, Czech MP. Cell Metab. 2007 5(4):237-52). In the liver, AMPK phosphorylates CRTC2, promoting its nuclear export, or the deacetylases HDAC4 / 5 / 7, promoting the nuclear export of FOXO1. Both of these pathways suppress hepatic gluconeogenesis and lower blood glucose (Altarejos JY, Montminy M. Nat Rev Mol Cell Biol. 2011 12(3):141-51). Furthermore, activation of AMPK promotes lipolysis and fatty acid oxidation in obese mice, reducing liver fat content and adipose tissue volume, thereby achieving the beneficial effects of dieting (Garcia D et al., Cell Rep. 2019 26(1):192-208; Pollard A et al., Nature Metab. 2019 1:340-349). Therefore, AMPK activators have important effects in producing medicines that reduce fatty acid synthesis, inhibit triglyceride and cholesterol synthesis, and prevent and / or treat obesity and type II diabetes.

[0004] Furthermore, because AMPK has multifunctional effects on the metabolism and biosynthesis of carbohydrates, fats, and cholesterol, these effects are closely related to Parkinson's disease and Alzheimer's disease (Nat. Rev. Mol. Cell Biol. 2014, 15, 634-646.), and the extension of lifespan in living organisms (Curr. Biol. 2007, 17, 1646-1656, Cell Metab. 2013, 17, 101-112, Cell Metab. 2014 20, 10-25, and Nat. Commun. 2013, 4, 2192.), AMPK activators play an important role in the production of pharmaceuticals for preventing and / or treating Parkinson's disease, Alzheimer's disease, or extending the lifespan of mammals.

[0005] Despite AMPK's important role in metabolic regulation and human health, there are very few clinically available AMPK activators, and currently only metformin is used clinically as a first-line treatment for type 2 diabetes. Metformin's target organs are very limited, acting only on the liver and kidneys, while it has no regulatory effect on AMPK in tissues such as fat and muscle, which are closely related to metabolic regulation. Therefore, the search for broader AMPK activators has long been a focus of attention in both academia and industry. New approaches are needed to design and explore AMPK activators with novel structures, high safety, and high activity. Summary of the Invention [Problem to be solved by the invention]

[0006] The inventors of the present invention conducted extensive and thorough research to find novel AMPK activators, and as a result, designed and synthesized polysubstituted fluorine-containing imidazole salt derivatives that have novel structures, are highly safe, and have high activity, and further investigated the effects of these novel derivatives on the AMPK signaling pathway.

[Brief explanation of the drawings]

[0013] [Figure 1]Figure 1 shows the AMPK activation levels of representative compounds in MEF cells. Figure 1 shows that the compounds can activate AMPK in mouse embryonic fibroblasts (MEFs). The results clearly show that the test compounds at 10 nM effectively activate AMPK and promote the phosphorylation of AMPK (p-AMPK) and its downstream substrates ACC1 / ACC2 (p-ACC). [Figure 2] The possible metabolic pathways of LXY-Cl in a human hepatocyte incubation system are shown. The results show that LXY-Cl is metabolized to multiple different metabolites in human hepatocytes, with a relative content of 21% of the residual drug substance after 120 minutes of incubation. [Figure 3] The possible metabolic pathway of IB-33 in a human hepatocyte incubation system is shown. The results clearly show that IB-33, a fluorine-containing substituted compound corresponding to LXY-Cl, is relatively stable in human hepatocytes, with a relative content of 79% of the residual drug substance after 120 minutes of incubation. Comparison of the metabolite data for IB-33 and LXY-Cl in hepatocytes revealed that the metabolic stability of fluorine-containing compounds is significantly improved. [Figure 4] We show that IB-33 effectively reduces body weight in a high-fat diet-fed obese mouse model. [Figure 5] We demonstrate that IB-33 can effectively reduce hepatic fat accumulation in a high-fat diet-fed obese mouse model. [Figure 6] Glucose tolerance tests in mice show that IB-33 effectively lowers blood glucose. [Figure 7] Figure 7 shows that compound IB-33 effectively lowers blood glucose in an ip-GTT.

For oral administration, the active compound may be combined with one or more excipients and used in the form of swallowable tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, tablets, and the like. Such compositions and preparations contain at least 0.1% of the active compound. The percentage of such compositions and preparations may, of course, vary and may represent from about 1% to about 99% by weight of a given unit dosage form. In such therapeutically useful compositions, the amount of active compound is such that an effective dosage level can be obtained.

[0060] Tablets, troches, pills, capsules, and the like may contain binders such as tragacanth gum, gum arabic, corn starch, or gelatin; excipients such as dicalcium hydrogen phosphate; disintegrants such as corn starch, potato starch, alginic acid, and the like; lubricants such as magnesium stearate; and sweeteners such as sucrose, fructose, lactose, and aspartic acid; or flavoring agents such as peppermint, wintergreen oil, and cherry flavor. When the unit dosage form is a capsule, in addition to the above materials, it may contain a liquid carrier such as vegetable oil or polyethylene glycol. Various other materials may be present as coatings or to otherwise modify the physical form of the solid unit dosage form. For example, tablets, pills, or capsules may be coated with gelatin, wax, shellac, sugar, and the like. A syrup or elixir may contain the active compound, sucrose or fructose as a sweetener, methyl or propyl parahydroxybenzoate as a preservative, a dye, or a flavoring agent (such as cherry or orange flavor). Of course, any material used to prepare any unit dosage form should be pharmaceutically acceptable and substantially non-toxic in the amounts applied. Moreover, the active compound can be incorporated into sustained-release preparations and devices.

[0061] The active compound can also be administered intravenously or intraperitoneally by infusion or injection. Aqueous solutions of the active compound or its salts can be prepared, and non-toxic surfactants can be added as needed. Dispersions can also be prepared in glycerin, liquid polyethylene glycol, triglycerides and their mixtures, and oils. Under normal storage and use conditions, these preparations contain preservatives to prevent the growth of microorganisms.

[0062] Pharmaceutical dosage forms suitable for injection or infusion can include sterile aqueous solutions or dispersions or sterile powders of the active ingredient (optionally encapsulated in liposomes) for extemporaneous preparations, including sterile injectable or infusible solutions or dispersions. In all cases, the final dosage form must be sterile, fluid, and stable under the conditions of manufacture and storage. Liquid carriers can be solvents or liquid dispersion media containing, for example, water, ethanol, polyols (e.g., glycerin, propylene glycol, liquid polyethylene glycol, etc.), vegetable oils, non-toxic glycerides, and suitable mixtures thereof. Proper fluidity can be maintained, for example, by the formation of liposomes, the maintenance of the desired particle size in the case of dispersions, or the use of surfactants. Prevention of microorganisms can be achieved by various antibacterial and antifungal agents (e.g., parahydroxybenzoates, chlorobutanol, phenol, sorbic acid, thimerosal, etc.). In many cases, it is preferable to include isotonic agents such as sugars, buffers, and sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in compositions delaying absorption, for example, aluminum monostearate and gelatin.

[0063] Sterile injectable solutions are prepared by combining the required amount of the active compound in an appropriate solvent with various other required ingredients as described above, followed by filtration and sterilization. For preparing sterile powders for sterile injectable solutions, the preferred preparation methods are vacuum drying and freeze-drying techniques, which produce powders containing the active ingredient plus any additional required ingredients present in the conventional sterile-filtered solution.

[0064] Useful solid carriers include pulverized solids (e.g., talc, clay, microcrystalline cellulose, silica, alumina, etc.). Useful liquid carriers include water, ethanol, ethylene glycol, or water-ethanol / ethylene glycol mixtures, and the compounds of the present invention can be dissolved or dispersed in the above carriers at an effective content, optionally with the aid of non-toxic surfactants. Adjuvants (e.g., flavors) and additional antimicrobial agents may be added to optimize the properties for a given application.

[0065] Thickeners (e.g., synthetic polymers, fatty acids, fatty acid salts and esters, fatty alcohols, modified cellulose, or modified inorganic materials) may be combined with a liquid carrier to form spreadable pastes, gels, ointments, soaps, etc., for application directly to the user's skin.

[0066] The therapeutic amount of the compound or its active salt or derivative will depend not only on the particular salt selected, but also on the mode of administration, the nature of the disease being treated, and the age and condition of the patient, and ultimately on the decision of the attending physician or clinician.

[0067] The above-mentioned preparations are physically dispersed units containing a unit dose and can be in a unit dosage form suitable for administration to the human body or other mammalian body. The unit dosage form can be a capsule or tablet, or a number of capsules or tablets. The amount of the unit dosage of the active ingredient can be varied or adjusted between about 0.1 mg and about 1000 mg or more depending on the specific treatment involved.

[0068] Additionally, various new dosage forms of pharmaceuticals, including the application of liposomes, microspheres, and nanospheres, include drugs prepared using particulate dispersion systems, including polymeric micelles, nanoemulsions, submicroemulsions, microcapsules, microspheres, liposomes, and niosomes (also called non-ionic surfactant vesicles).

[0085] Test Example Biological activity testing 1. Testing AMPK activity at the cellular level The AMPK activation ability of the compounds was tested in mouse embryonic fibroblasts (MEFs) by Western blot analysis, specifically by detecting the phosphorylation level of AMPK at threonine 172 (p-AMPKα) and the phosphorylation level of AMPK substrate ACC1 / ACC2 at serine 79 (p-ACC) (Figure 1 and Table 1). The specific method is as follows: (1) MEFs carrying loxP insertions or wild-type MEFs were seeded onto 6-well plates and cultured in DMEM containing 10% serum. If a gene needed to be knocked out, an adenovirus capable of expressing cre was added to the culture well when the confluency of the corresponding MEFs carrying loxP insertions reached approximately 30%, and the culture was continued for at least 24 hours. (2) When the cell density approached 90%, the cells were replaced with fresh DMEM, and the compounds (final concentration 10 nM) were added to the cells and cultured for 2 hours. An equal volume of DMSO was used as a negative control, and cells treated with AICAR (3 mM) were used as a positive control. (3) The culture medium was aspirated and discarded, and the cells were lysed with 200 μL of cell lysis solution (formulation described below). The cells were scraped from the dish, ultrasonically disrupted, and centrifuged at 20,000 g for 10 minutes at low temperature. (4) The supernatant was mixed with an equal volume of 2*SDS solution (formulation described later) and loaded onto an 8% SDS-PAGE gel. The proteins were then transferred onto PVDF membranes, each of which was blocked with 25 mL of nonfat milk for 1 hour and then rinsed three times with TBST buffer (formulation described later) for 10 minutes each. (5) Primary antibodies against the AMPK α subunit (Cell Signaling Technology, #2532), AMPK threonine 172 phosphorylation primary antibody (Cell Signaling Technology, #2535), ACC primary antibody (Cell Signaling Technology, #3662), and ACC serine 79 phosphorylation primary antibody (Cell Signaling Technology, #3661) were diluted 1:1000 in primary antibody diluent (formulation described below) and reacted with the PVDF membrane at room temperature for 12 hours, then rinsed three times with TBST buffer. (6) HRP-conjugated goat anti-rabbit secondary antibody (Jackson ImmunoResearch, 111-035-003) diluted 1:1000 was added, and the reaction was allowed to proceed at room temperature for 1 hour, followed by rinsing three times with TBST buffer. (7) The PVDF membrane was wiped dry, reacted with ECL mixture (WesternBright ECL HRP substrate, Advansta), exposed and developed using medical X-ray film, and finally rinsed and baked, then scanned to obtain relevant data on AMPK activation. Reagent formulation used: Cell lysis solution: 20 mM Tris-base, pH 7.5, 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 2.5 mM sodium pyrophosphate, 1 mM β-glycerolphosphate, 1% Triton X-100 (v / v); 2*SDS solution: 20% glycerol (v / v), 4% SDS (m / v), 10% β-mercaptoethanol (v / v), 0.01% bromophenol blue (m / v); TBST buffer: 4.84% Tris-base (m / v), 8% NaCl (m / v), 0.1% Tween-20 (v / v); Primary antibody dilution solution: TBST buffer containing 5% BSA (v / v)

[0090] 4. Evaluation of the in vivo efficacy of compound IB-33 Subcutaneous administration of compound IB-33 effectively reduced body weight and improved liver fat accumulation in a high-fat diet-fed obese mouse model. Post-administration mouse weight (Figure 4) and liver section morphology (Figure 5) revealed that IB-33 was highly effective in reducing body weight and treating fatty liver. Western blot analysis of AMPK threonine 172 phosphorylation and AMPK substrate ACC1 / ACC2 serine 79 phosphorylation revealed that IB-33 effectively activated AMPK in mice (Figure 6). The specific method is as follows: (1) Six-week-old wild-type C57BL / 6J male mice were fed a high-fat diet containing 60% fat. After 10 weeks, when their body weight reached approximately 50 g, administration began, and the high-fat diet was continued during the administration period. (2) Mice were weighed at 5:00 PM every day and were administered IB-33 subcutaneously (sc) at concentrations of 0.05, 0.15, or 0.3 mg / kg once every two days, along with vehicle at the same dose. (3) The mice were continuously raised for 90 days, and their weights were weighed and recorded daily. On the 90th day, some of the mice were euthanized, and their livers were collected, fixed, sectioned, and stained with HE staining to directly observe their histological characteristics. (4) After 90 days of administration, some mice were killed by cervical dislocation, and their livers were quickly removed and placed in 1.5 mL tubes and quenched with liquid nitrogen. (5) Approximately 50 mg of liver was cut, and a cell lysis solution (formulation described below) was added at a ratio of 1 mg / μL. The liver was homogenized, ultrasonically disrupted, and centrifuged at 20,000 g for 10 minutes at low temperature. (6) The supernatant was mixed with an equal volume of 2*SDS solution (formulation described later) and loaded onto an 8% SDS-PAGE gel. The proteins were then transferred onto PVDF membranes, each of which was blocked with 25 mL of nonfat milk for 1 hour and then rinsed three times with TBST buffer (formulation described later) for 10 minutes each time. (7) Primary antibody against AMPK α subunit (Cell Signaling Technology, #2532), primary antibody against AMPK threonine 172 phosphorylation (Cell Signaling Technology, #2535), primary antibody against ACC (Cell Signaling Technology, #3662), and primary antibody against ACC serine 79 phosphorylation (Cell Signaling Technology, #3661) were diluted 1:1000 in primary antibody diluent (formulation described below) and reacted with the PVDF membrane at room temperature for 12 hours, then rinsed three times with TBST buffer. (8) HRP-conjugated goat anti-rabbit secondary antibody (Jackson ImmunoResearch, 111-035-003) diluted 1:1000 was added, and the mixture was allowed to react at room temperature for 1 hour, followed by rinsing three times with TBST buffer. (9) The PVDF was wiped dry, reacted with ECL mixture (WesternBright ECL HRP substrate, Advansta), exposed and developed using medical X-ray film, and finally rinsed and baked, and then scanned to obtain relevant data on AMPK activation. Reagent formulation used: Cell lysate: 20mM Tris-base, pH 7.5, 150mM NaCl, 1mM EDTA, 1mM EGTA, 2.5mM Sodium pyrophosphate, 1mM β-glycerolphosphate, 1% Triton X-100 (v / v); 2*SDS solution: 20% Glycerol (v / v), 4% SDS (m / v), 10% β-mecaptoethanol (v / v), 0.01% Bromophenol blue (m / v); TBST buffer: 4.84% Tris-base (m / v), 8% NaCl (m / v), 0.1% Tween-20 (v / v); Primary antibody dilution solution: TBST buffer containing 5% BSA (v / v) Compound IB-33 can effectively lower blood glucose in a glucose tolerance test in mice, and FIG. 7 shows that compound (IB-33) effectively lowers blood glucose in an ip-GTT. (14) Six-week-old wild-type C57BL / 6J male mice were fasted for 4 hours from 6:00 AM, and blood glucose (-120 min) was measured and the mice were weighed. IB-33 was administered intragastrically at doses of 0.2 and 2 mg / kg, and vehicle was administered intragastrically at the same ratio. (15) After 2 hours, blood glucose (0 min) was measured, and the mice were intraperitoneally injected with 20% (v / v) glucose solution at a concentration of 1 g / kg. The blood glucose of the mice was measured 20, 40, 60, and 90 min after injection, respectively.
