Abstract
Description
[0001] Cross-reference to related applications
[0002] This patent application claims priority to Italian patent application No. 102020000019210, filed on August 4, 2020, the entire disclosure of which is incorporated herein by reference. Technical Field
[0003] This invention relates to the use of quinoline derivatives and their ability to simultaneously modulate bile acid receptors (FXR and GPBAR1) and cysteyl leukotriene receptors (CysLTR), and their use for the treatment and / or prevention of diseases mediated by the latter. Background Technology
[0004] The strategy of identifying small molecules that can act on multiple targets simultaneously is widely considered to be a novel pharmacological approach for identifying multifactorial diseases such as chronic inflammatory conditions, including non-alcoholic steatohepatitis, highly prevalent inflammatory liver diseases, metabolic syndrome, and cancer.
[0005] This study begins with our recent observation that REV5901 (a cysteyl-leukotriene receptor antagonist) can modulate GPBAR1 in an animal model of intestinal inflammation to exhibit interesting anti-inflammatory activity, and that Zafirlukast (a well-known CysLT receptor antagonist) has weak activity against FXR (S. Schierle et al. Anti-Inflammatory Potency of Zafirlukast by Designed Polypharmacology, J Med Chem 61(13)(2018) 5758-5764).
[0006] Leukotrienes are a large family of lipid regulators that are produced from arachidonic acid via an enzymatic cascade and function as regulators of inflammation. Among leukotrienes, cysteyl leukotrienes (CysLTs) include LTC4, LTD4, and LTE4, which act on cells by binding to the G protein-associated transmembrane protein family (CysLTRs) expressed on many pro-inflammatory cells, such as neutrophils and eosinophils, mast cells, and monocytes / macrophages. These receptors play important roles in inflammatory responses leading to microvascular permeability, leukocyte transport, chemokine and cytokine secretion, and tissue repair (fibrosis) through activation of endogenous lipid regulators. Cysteine leukotriene receptors are well known to mediate bronchoconstriction, pulmonary mucus secretion, and edema, and thus their antagonists are proven effective drugs in the treatment of asthma and more generally in pharmacological approaches targeting lung diseases. Cysteinyl leukotrienes are involved in many other diseases, such as cardiovascular disease, cancer, atopic dermatitis, rheumatoid arthritis, Crohn's disease, as well as the pathogenesis of fulminant hepatitis and hepatic cholestasis, fibrosis and cirrhosis (Capra V. et al. Cysteinyl-leukotrienes and their receptors in asthma and other inflammatory diseases: critical update and emerging trends. (Med Res Rev. 2007 Jul; 27(4):469-527).
[0007] FXR, highly expressed in the enterohepatic tissues (liver and intestine), regulates bile acid homeostasis and several metabolic pathways, including lipid and glucose metabolism. FXR agonists have been shown to be useful in pharmacological approaches targeting metabolic disorders such as cholestasis, type 2 diabetes, liver fibrosis, and non-alcoholic fatty liver disease (NAFLD). Furthermore, FXR plays important roles in the kidneys, cardiovascular system, and tumorigenesis (Renga et al. PHASEB J. 2012, 26, 3021-3031).
[0008] GPBAR1 is highly expressed in the liver and intestine, as well as in muscle, adipose tissue, macrophages, and endothelial cells. In muscle and brown adipose tissue, GPBAR1 increases energy expenditure and oxygen consumption (Watanabe et al., Nature of 2006, 439, 484). In enteroendocrine L cells, GPBAR1 activation stimulates the secretion of glucagon-like peptide-1 (GLP-1), thereby regulating blood glucose levels, gastrointestinal motility, and appetite (Thomas et al., Cell. Metab. 2009, 10, 167).
[0009] GPBAR1 appears to be associated with the regulation of inflammatory processes and immune function. Many innate immune cells, such as monocytes, macrophages, NKT cells, and dendritic cells, express this receptor, and mutations in this receptor are associated with an increased risk of developing primary sclerosing cholangitis and ulcerative colitis.
[0010] Purpose of the invention
[0011] The purpose of this invention is to identify novel compounds that can selectively or simultaneously modulate bile acid receptors (FXR and GPBAR1) and cysteine leukotriene receptors (CysLTR).
[0012] Such an objective is achieved by the compounds of formula (I) according to claim 1, their uses according to claims 8 and 9, and their compositions according to claim 10. Preferred embodiments are indicated in the dependent claims.

[0020] Preferred embodiments of the present invention
[0021] The following paragraphs provide the chemical characteristics of the compounds according to the invention and are intended to apply uniformly throughout the specification and all claims, unless otherwise expressly stated to provide a more broad definition.
[0022] As used herein, the term "alkyl" refers to a saturated aliphatic hydrocarbon. This term includes both straight (unbranched) and branched chains.
[0023] Non-limiting examples of alkyl groups according to the present invention include, for example, methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, n-hexyl, etc.
[0024] As used herein, the term "hydroxyalkyl" refers to a saturated aliphatic carbohydrate in which one or more hydrogen atoms are replaced by hydroxyl groups.
[0025] Unless otherwise stated, as used herein, the term “substituted” means that one or more hydrogen atoms of the aforementioned group are replaced by other non-hydrogen atoms or functional groups, provided that the normal valence electrons remain unchanged and the substitution produces a stable compound.
[0026] Those skilled in the art of organic chemistry will understand that many organic compounds can form complexes with solvents in which they react, precipitate, or crystallize. These complexes are called "solvates." For example, complexes with water are called "hydrates." The solvates of the compounds of this invention are within the scope of this invention. The compounds of formula (I) or (Ia) associated with solvent molecules can be readily isolated to provide the corresponding solvates by crystallization or evaporation of a suitable solvent.
[0027] The compounds of formula (I) or (Ia) may be in crystalline form. In some embodiments, the compounds of formula (I) or (Ia) are polymorphic.
[0028] The present invention also includes isotopically labeled compounds that are identical to those given in formula (I) or (Ia), but differ in that one or more atoms are replaced by atoms with atomic masses or mass numbers different from those normally found in nature. Examples of isotopes that can be incorporated into the compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, and oxygen, for example... 2 H, 3 H, 11 C 13 C 14 C 15 N、 17 O.
[0029] Compounds of the present invention containing the aforementioned isotopes and / or other atoms, and other isotopes thereof, are within the scope of protection of the present invention. Isotope-labeled compounds of the present invention, for example, those doped with radioactive isotopes, are also included. 3 H and 14 Those with C can be used to determine the tissue distribution of drugs and / or substrates. Tritium isotopes, i.e. 3 H, and carbon-14, i.e. 14 C, is particularly preferred due to their ease of preparation and detectability. Isotopes 11 C is particularly useful for PET (positron emission tomography). Additionally, heavier isotopes (such as deuterium, i.e., 2 Substitution of H) can provide certain therapeutic advantages resulting from increased metabolic stability (e.g., increased in vivo half-life or reduced dosing requirements), and may therefore be mentioned in some cases. The isotopically labeled compounds of formula (I) or (Ia) of the present invention can generally be prepared by performing the process described in the following schematic diagrams and / or examples (replacing the non-isotopically labeled reactant with an readily available isotopically labeled reactant).
[0030] Some of the groups / substituents included in this invention can exist as isomers. Therefore, in some embodiments, compounds of formula (I) or (Ia) can have axial asymmetry and, correspondingly, can exist as optical isomers, such as form (R), form configuration (S), etc. All such isomers, including racemic mixtures, enantiomers, and mixtures thereof, are included within the scope of this invention.
[0031] In particular, the scope of protection of this invention includes all stereoisomers, including enantiomers, diastereomers and mixtures thereof, including racemates, and unless otherwise stated, compounds of formula (I) or (Ia) generally referred to include all stereoisomers.
[0032] Generally, the compounds of this invention should be considered to exclude those compounds that are chemically very unstable, either on their own or in water (if any), and which are clearly unsuitable for pharmaceutical use by all routes of administration, whether oral, parenteral, or otherwise. Such compounds are known to a skilled chemist.
[0033] Finally, compounds of formula (I) or (Ia) can form salts. In particular, the quinoline ring can form hydrochloride salts, while phenolic residues or COOH groups can form metal salts.

[0114] Compounds of formula (Ia) may be included in pharmaceutical compositions and their dosage units together with conventionally used excipients and in such form as to be used as solids (e.g., tablets or filled capsules) or liquids (e.g., solutions, suspensions, emulsions, elixirs, or capsules filled with compounds of formula (Ia) together with conventionally used excipients), all for oral use or as sterile injectable solutions for parenteral administration (including subcutaneous and intravenous use).
[0115] Such pharmaceutical compositions and their unit dosage forms may contain ingredients in conventional percentages, with or without additional compounds or active ingredients, and such unit dosage forms may contain any appropriate effective amount of active ingredient commensurate with the intended range of daily doses to be used.
[0116] Pharmaceutical compositions containing compounds of the present invention can be prepared in a manner well known in the pharmaceutical industry and comprise at least one active compound. Generally, the compounds of the present invention are administered in pharmaceutically effective amounts.

In some embodiments, one or more active ingredients in the pharmaceutical compositions of the present invention are typically formulated as dosage units. Dosage units may contain 0.1 to 1000 mg of a compound of formula (Ia) per dosage unit for daily administration.
[0125] In some embodiments, the effective amount of a particular formulation will depend on the severity of the pre-treatment disease, disorder, or condition, the individual's health status, and response to the drug. In some embodiments, the dose ranges from 0.001% by weight to about 60% by weight of the formulation.
[0126] When used in combination with one or more other active ingredients, the compounds and other active ingredients of the present invention can be used at lower doses than when used individually.

[0152] Reagents and conditions: a) DIBAL-H, dry THF, 0℃; b) PPh3, DIAD, dry THF, 0℃; c) NaOH, MeOH:H2O 1:1 v / v.
[0153] General process.
[0154] Reaction a). Reduction with DIBAL-H. At 0°C, a solution of DIBAL-H (2.0 equivalents, 1.0 M in THF) was added dropwise to a solution of quinoline methyl ester or a solution of CHIN104 in anhydrous THF (25 mL). The resulting mixture was stirred at 0°C for 4–8 hours. A saturated aqueous solution of Rochelle salt (potassium sodium tartrate) was added to the reaction mixture, followed by dilution with DCM. Quenching was performed with stirring for two hours. The aqueous phase was extracted with DCM (3 x 50 mL), and the collected organic phase was washed with water, dehydrated with Na2SO4, and concentrated under vacuum on a rotary evaporator to obtain a crude residue, which was purified by column chromatography or HPLC.
[0155] Step b) Photoelectrophoresis. At 0°C, diisopropyl azodicarboxylate (DIAD, 3.5 equivalents) was added dropwise to a solution of triphenylphosphine (PPh3, 3.5 equivalents) in dried THF. After 10 minutes, a solution of alcohol 1 dissolved in dried THF was added. After another 10 minutes, a solution of methyl 3-hydroxybenzoate dissolved in dried THF was added. After approximately 12 hours, water was added and the reaction mixture was dried to remove THF. The dried residue was extracted with EtOAc (3 x 50 mL), and the collected organic phase was washed with 2.5 M KOH aqueous solution and water, dehydrated, and dried under vacuum on a rotary evaporator. Purification on a column and silica gel yielded CHIN104.
[0156] Step c) Alkaline hydrolysis. A small fraction of CHIN104 ester was dissolved in a MeOH:H₂O 1:1 v / v (30 mL) solution and treated with NaOH (5.0 equivalents) under alkaline conditions. The reaction mixture was stirred under reflux at approximately 150 °C for 8 hours. The resulting solution was quenched with 6 M HCl and then extracted with EtOAc (3 x 50 mL). The collected organic phase was washed with water, treated with anhydrous Na₂SO₄, and then dried on a rotary evaporator to obtain CHIN105 as a crude residue, which was further purified.

[0158] Purification was achieved using a hexane:EtOAc 9:1 v / v and 0.1% TEA as the eluent mixture via silica gel, yielding CHIN104 (78%). Sample analysis was performed on a Nucleodur 100-5C18 column (5 μm; 10 mm id x 250 mm) with MeOH / H2O 82:18 v / v as the eluent (flow rate 3 mL / min, t).

[0172] Example 2. Synthesis of CHIN107, CHIN108 and CHIN109.
[0173] For the synthesis of compounds CHIN107-CHIN109, the first step involved monoprotecting methyl 3,5-dihydroxybenzoate, which must bind to quinoline, with TBS. After obtaining the monoprotected derivative, it binds to quinoline via the Williamson reaction between (phenol) and methanesulfonyl alcohol derivative 1. The final step was deprotection of TBS with tetrabutylammonium fluoride (TBAF) to obtain CHIN107. The esters from two aliquots were subjected to alkaline hydrolysis and reduction with DIBAL-H to obtain CHIN108 and CHIN109.

Purification on silica gel using a hexane / EtOAc 9:1 mixture as the eluent yielded compound 3 in 45% yield.
[0179] Reaction b). Methanesulfonation of alcohol 1. Compound 1 was dissolved in dry diethyl ether, and triethylamine (6 equivalents) and methanesulfonyl chloride (5 equivalents) were added to the solution at -20°C. After about 1 hour, the solution was washed with a saturated aqueous solution of NaHCO3, and the collected organic phase was extracted once with water.

[0180] Reaction c). Williamson reaction. Potassium carbonate (2.5 equivalents) was added to a solution of (phenol) in DMF (compound 3) and allowed to stand for 15 minutes. A methanesulfonic acid derivative (1.2 equivalents, compound 4) dissolved in dry DMF was added, and the solution was kept at 100°C for approximately 12 hours. The DMF was cooled and removed by rotary evaporation. The solid residue was extracted with water and ethyl acetate (3 x 50 mL). The collected organic phase was dehydrated with Na₂SO₄, filtered, and then concentrated by rotary evaporation to obtain a crude reaction product, which was directly used for subsequent reactions.
[0181] Reaction d) Deprotection from TBS. At room temperature, the crude product from the previous reaction was dissolved in dry THF, and a 1.0 M TBAF tetra-N-butylammonium fluoride solution (0.63 mL, 5 equivalents) in THF was added to the solution. The reaction was completed after 8 hours and treated by adding AcOEt and extraction with H2O.

[0346] Example 7 - Biological Data
[0347] Table 1 describes the activity data of the compounds of the present invention against the FXR, TGR5 / GPBAR1, and CysLT1R receptors. In this table, the activities of the compounds are compared with specific reference compounds (i.e., CDCA for FXR, TLCA for TGR5 / GPBAR1, and MK571 for CysLT1R). Each compound was tested at a concentration of 10 μM, and the activity of the reference compounds was considered 100%.
[0348] Table 1
[0349]
[0350]
[0351] For FXR-mediated transcriptional activation, HepG2 cells were transfected with 200 ng of the p(hsp27)-TK-LUC reporter vector containing the FXR response element (IR1) cloned from the heat shock protein 27 (hsp27) promoter, 100 ng of pSG5-FXR, 100 ng of pSG5-RXR, and 100 ng of the vector pGL4.70 (Promega, Madison WI) encoding the human Renilla gene.
[0352] For GPBAR1-mediated transcriptional activation, HEK-293T cells were transfected with 200 ng of the reporter vector pGL4.29 (Promega, Madison WI) containing the cAMP response element (CRE) that drives the transcription of the luc2P luciferase reporter gene, 100 ng of human pCMVSPORT6-GPBAR1, and 100 ng of pGL4.70.
[0353] Twenty-four hours post-transfection, cells were stimulated for 18 hours with the specific receptor agonist CDCA (10 μM) or TLCA (10 μM), or with derivatives CHIN104-112 and CHIN114-121 (10 μM and 50 μM). In another experimental setup, cells were stimulated for 24 hours post-transfection with 50 μM of the derivative CHIN in combination with 10 μM CDCA or TLCA.
[0354] For dose-response curves, cells were stimulated with increasing concentrations of the target compound (0.1–75 μM). Eighteen hours post-stimulation, cell lysates were used to assess luciferase and Renilla activities using a dual-luciferase reporter assay (E1980, Promega Madison WI). Luminescence was measured using a Glomax 20 / 20 spectrophotometer (Promega, Madison WI), and luciferase activity was normalized using Renilla activity.
[0355] Antagonistic activity was detected using Eurofins Cerep-Panlabs (France). Cells were suspended in DMEM buffer (Invitrogen) and then... 4 Cells were seeded at a density of 100 cells / plate. A fluorescent probe (Fluo4Direct, Invitrogen) mixed with probenecid was then added to each well in HBSS buffer (Invitrogen) supplemented with 20 mM Hepes (Invitrogen) (pH 7.4) and incubated with cells at 37°C for 60 min, followed by 22°C for 15 min. The plate was then placed on a microplate reader (CellLux, PerkinElmer) for adding the test compound or HBSS buffer, followed by 0.1 nM LTD4 or HBSS buffer solution (as a control) after 5 min. Free Ca2+ in the cytosol was measured. 2+ The intensity and fluorescence changes proportionally to the ion concentration. Results are expressed as the percentage of inhibition compared to the control response with 0.1 nMLTD4. The standard antagonist reference is MK571.
[0356] CHIN117 and its role in reducing acetaminophen-induced liver injury (APAP) are of particular interest. In the experimental setup, acute hepatitis was induced in wild-type C57 / Bl6 mice by oral administration of acetaminophen (APAP) at a concentration of 500 mg / kg. Forty-five minutes after induction, CHIN117 was administered orally at a concentration of 30 mg / kg. Mice were sacrificed 24 hours after induction, and blood was collected for analysis of blood cell counts and AST and ALT transaminase levels.
[0357] The results show ( Figure 1-3 APAP administration induced a sharp increase in AST and ALT levels (between 3000 and 4000). Furthermore, the resulting liver damage attracted immune cells involved in the pathogenesis of the disease to the liver, leading to a decrease in circulating white blood cell (WBC) levels. Administration of the compound CHIN117 alleviated APAP-induced liver damage by reducing AST and ALT levels approximately 10-fold compared to those recorded in mice treated with APAP alone. CHIN117 also maintained WBC levels comparable to those found in untreated mice (NT).
[0358] CHIN117 and its efficacy in a mouse model of chronic hepatitis induced by a high-fat diet are of particular interest. This mouse model mimics NAFLD, representing a rapidly growing epidemic in industrialized countries and imposing very high costs on healthcare systems. In this model, mice (male C57BL / 6 mice) were fed a diet rich in lipids and cholesterol (2% cholesterol) with fructose (3%) added to the water (HFD-F) for 60 days. Starting from day 7, CHIN117 was administered daily at a dose of 30 mg / kg. Weight trend showed that CHIN117 reduced weight gain by approximately 3 grams. Figure 4 A, B). After eight weeks, the mice developed insulin resistance, as shown in the OGTT results ( Figure 4 E, F). Treatment of mice with CHIN117 reversed the effects of diet and reduced the AUC of OGTT. Furthermore, CHIN117 statistically reduced AST, ALT, and LDL levels, thereby offsetting the hepatotoxic effects of the HFD-F diet. Figure 4 GH).
[0359] Mice fed the HFD-F diet for 8 weeks developed features similar to human NASH as revealed by H&E staining in liver sections, including microcystic steatosis, hepatocyte swelling, lobular inflammation, and macrophage influx. Figure 5 A), thus leading to a significant increase in the hepatic steatosis (NAS) score. Figure 3B). Furthermore, HFD-F indicates an increase in body mass index (BMI), epididymal white adipose tissue (eWAT) weight, brown adipose tissue (BAT) weight, and liver weight. Figure 5 CI). CHIN117 almost completely reversed the disease by reducing hepatic steatosis, BMI and eWAT, BAT and liver weight (CI). Figure 5 ).
[0360] CHIN117 is valued for its excellent pharmacokinetic properties (water solubility of 66 μM at pH 7.4 and LogD = 2.0) and its promising metabolic stability (t < 0.0 when exposed to microsomal enzymes in vitro). 1 / 2 =578min(CL) int =4), and exposed in vitro to S9 stage time-sharing t which also contains enzymes responsible for the second stage of metabolism. 1 / 2 =385min(CLint=6)) and is particularly noteworthy.
