Abstract
Description
[Background technology]
[0001] Estrogen-related receptor alpha (ERRα) is a 45.5 kilodalton (kDa), 423 amino acid residue protein that belongs to the nuclear receptor (NR) superfamily. This nuclear receptor family is composed of 48 genes that encode DNA-binding transcription factors involved in the regulation of diverse functions, including homeostasis, reproduction, development, and metabolism, among others. The ERR family, i.e., the NR3B subgroup, is composed of ERRα, ERR-β, and ERR-γ: to date, no endogenous ligands have been identified for any of the ERR isoforms, and therefore they are considered orphan receptors.
[0002] In Bookout et al., Anatomical profiling of nuclear receptor expression reveals a hierarchical transcriptional network, Cell. 126:789-99 (2006), organism-wide expression profiling of the three ERR isoforms determined that ERRα is widely distributed, with significant protein expression in most adult tissues. Knockout studies of ERR family members revealed that each receptor has a tissue- and function-specific metabolic phenotype that is important for adaptation to energy stress at the systemic level. Knockout studies also showed limited in vivo compensation among ERR family members. Notably, Tremblay et al., The NR3B subgroup: an overview, Nuclear receptor signaling, 5:e009 (2007) may be noted in this context.
[0003] Genomic studies have shown that ERRα regulates a large number of genes. The following references are informative in this regard: Puigserver et al., A cold-inducible coactivator of nuclear receptors linked to adaptive thermogenesis, Cell. 92(6):829-839 (1998); Yoon et al., Control of hepatic gluconeogenesis through the transcriptional coactivator PGC-1, Nature 413 (6852):131-138 (2001); Huss et al., Estrogen-related receptor alpha directs peroxisome proliferator-activated receptor at signaling in the transcriptional control of energy metabolism in cardiac and skeletal muscle, Mol. Cell Biol. 24(20):9079-9091 (2004); and Mootha et al., ERRα and Gabpa / b specify PGC-1alpha-dependent oxidative phosphorylation gene expression that is altered in diabetic muscle, Proc. Natl. Acad. Sci. USA, 101(17):6570-6575 (2004).
[0004] These references support a physiological model of ERRα function in the regulation of energy metabolism, particularly in the transcriptional regulation of genes required for mitochondrial biogenesis, the tricarboxylic acid cycle, oxidative phosphorylation, fatty acid oxidation, and lipid metabolism. In particular, ERRα induces the expression of Nuclear Respiratory Factor 1 (NRF1), GA-binding protein alpha (GABPα), and Peroxisome Proliferator-activated Receptor alpha (PPARα). The nuclear receptor coactivators Peroxisome Proliferator-activated Receptor gamma coactivator 1-alpha (PGC-1α), PGC-1β, and Peroxisome Proliferator-activated Receptor gamma Coactivator-related protein 1 (PPRC-1) are involved in the regulation of these genes and in the autoregulation of ERRα expression. PGC-1α is expressed at low basal levels but is induced by fasting and other metabolic stresses. PGC-1β, a related coactivator, has a similar function, but its expression may be less rapidly regulated by fluctuations in energy demand. Conversely, co-repressors that bind to ERR, such as the corepressor Receptor Interacting Protein 140 (RIP140), compete with ERR coactivators to negatively regulate ERR-dependent gene expression.
[0005] The pleiotropic effects of ERRα activity on energy metabolism interest us as a target for the discovery of new therapeutic approaches for diseases in which metabolic disorders or modifications play a central role, such as type 2 diabetes, progressive heart failure, osteoporosis and cancer. Of particular interest is ERRα as a novel target for tumor therapy, via its impact on the regulation of tumor cell energy metabolism associated with energy stress within the tumor microenvironment. And of particular interest is ERRα as a novel target for the therapeutic treatment of cancers with stem cell-like properties - Cancer Stem Cells (CSCs), Tumor Initiating Cells (TICs) and Circulating Tumor Cells (CTCs) - which depend on mitochondrial respiration for their energy requirements.
[0006] In particular, cancer initiation and development are known to be associated with major metabolic changes, and mitochondria play a key role in tumorigenesis. A common abnormality observed in many types of cancer, called the Warburg effect, is a shift in glucose metabolism from oxidative phosphorylation to aerobic glycolysis, and is characterized by a dramatic increase in glucose consumption accompanied by an elevated ratio of lactate excretion rates, regardless of the amount of oxygen. Aerobic glycolysis meets the metabolic needs of highly proliferative cells, including providing sufficient energy and providing an accumulation of precursors for anabolic reactions. LeBleu et al., PGC-1alpha mediates mitochondrial biogenesis and oxidative phosphorylation in cancer cells to promote metastasis. Nat. Cell Biol. 16(10):992-1 (2014) demonstrated that tumor cells exhibit metabolic plasticity involving either glycolysis or oxidative phosphorylation depending on the tumor environment and their proliferation or metastatic phenotype during cancer progression. It is therefore apparent that targeting of metastatic progenitor cells and resistant tumor cells should occur not only via the glycolytic pathway, but also via mitochondrial oxidative phosphorylation.
[0007] ERRα, together with PGC1α / β, controls the regulation of genes encoding enzymes in the tricarboxylic acid (TCA) cycle and oxidative phosphorylation. As discussed in Ariazi et al., Estrogen-related receptor alpha and estrogen-related receptor gamma associate with unfavorable and favorable biomarkers, respectively, in human breast cancer, Cancer Res. 62(22):6510-8 (2002), ERRα is expressed in a variety of cancer cells, including breast and prostate cancer cells, and is associated with more aggressive disease and a higher risk of recurrence in both of these cancer types.
[0008] Chang et al., The metabolic regulator ERRa, a downstream target of HER2 / IGF-1R, as a therapeutic target in breast cancer, Cancer Cell 20, 500-510 (2011), and Fujimoto et al., Clinical implications of estrogen-related receptor (ERR) expression in ovarian cancers, J. Steroid Biochem. Mol. Biol. 104, 301-304 (2007) document that ERRa is expressed in most cancers and that increased activity of this receptor is associated with negative outcomes in both breast and ovarian cancers. The first of these references identifies transcription factors as also involved in the regulation of mitochondrial biogenesis and oxidative phosphorylation. This latter point is thought to be important since resistance to inhibition of the Kras pathway in pancreatic cancer, BRAF inhibitors in melanoma, and oxaliplatin and 5-fluorouracil in colon cancer have also been associated with a shift toward oxidative metabolism. Summary of the Invention [Problem to be solved by the invention]
[0009] Therefore, the inventors opined that inhibition of ERRα activity would allow selective disruption of mitochondrial function in cancer, particularly in the types of cancer mentioned above.To this end, but also for utility in treating other ERRα mediated diseases and conditions, the inventors developed non-covalent, non-steroidal ERRα inverse agonists.

[0062] The term "pharmaceutically acceptable salt" is used according to its standard definition in the art to denote salts that are suitable for use within the scope of medical judgment, particularly in contact with the tissues of humans and lower animals without undue toxicity, irritation and / or allergic reactions. Their use must be commensurate with a reasonable benefit to risk ratio. Pharmaceutically acceptable salts are well known in the art. They may be obtained during the final isolation and purification of the compounds of the invention, or they may be obtained separately by reacting the free base function with a suitable mineral acid, including but not limited to hydrochloric acid, phosphoric acid or sulfuric acid; or an organic acid, including but not limited to ascorbic acid, citric acid, tartaric acid, lactic acid, maleic acid, malonic acid, fumaric acid, glycolic acid, succinic acid, propionic acid, acetic acid or methanesulfonic acid. The acid function of the compounds of the invention may be reacted with an inorganic base, such as sodium hydroxide, potassium hydroxide or lithium hydroxide, or an organic base. For completeness, organic bases include common hydrocarbyl and heterocyclic amine salts such as diethylamino, morpholine and piperidine salts.
[0063] The compounds of formula I may contain asymmetric or chiral centers and therefore exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the compounds of formula I, as well as mixtures thereof, including racemic mixtures, form part of the present invention. In particular, the stereoisomers of the compounds of formula I in the S configuration of the chiral center next to the pyrazole ring according to the Cahn-Ingold-Prelog system of nomenclature, expressly form part of the present invention.
[0064] As will be appreciated by those skilled in the art, enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with a suitable optically active compound, for example a chiral auxiliary such as a chiral alcohol or Mosher's acid chloride; separating the diastereomers; and then converting the individual diastereomers into the corresponding pure enantiomers, for example by hydrolysis. Enantiomers can also be separated by use of a chiral HPLC column.

[0067] The present invention further includes compounds of Formula I in combination with one or more other pharmaceutical agents.
[0068] The compositions may be any unit dosage form for administration, including, but not limited to, those suitable for oral, sublingual, subcutaneous, intravenous, intramuscular, nasal, topical, or rectal administration.

[0069] For parenteral administration, the pharmaceutical compositions of the invention can be presented in unit-dose or multi-dose containers, such as sealed vials and ampoules, in a predetermined amount of injection solution. The pharmaceutical compositions can also be stored in a freeze-dried (lyophilized) condition requiring only the addition of a sterile liquid carrier, such as water, prior to use.
[0070] Mixed with such pharma- ceutically acceptable auxiliaries, the active agent can be compressed into solid dosage units, such as pills, tablets, or processed into capsules or suppositories. With pharma- ceutically acceptable liquids, the active agent can be applied as a fluid composition, for example in the form of a solution, suspension or emulsion, which can be included in a spray, for example an injection or nasal drops.
[0071] To prepare solid dosage units, the use of conventional additives, such as fillers, colorants, polymeric binders, etc., is contemplated. In general, any pharma- ceutically acceptable additive that does not interfere with the function of the active compound can be used. Suitable carriers that can be used by the active agent of the present invention as a solid composition include lactose, starch, cellulose derivatives, etc., or mixtures thereof, when used in appropriate amounts. For parenteral administration, aqueous suspensions, isotonic saline, and sterile injectable solutions can be used, and these suspensions or solutions can contain pharma- ceutically acceptable dispersants and / or wetting agents, such as propylene glycol or butylene glycol.
[0072] The present invention further includes a pharmaceutical composition as described hereinbefore in combination with suitable packaging material for said composition, wherein said packaging material contains instructions for use of the composition for the purposes as described hereinbefore.
[0073] The exact dosage and administration regimen of the active ingredient or pharmaceutical composition thereof may vary depending on the particular compound, the route of administration, and the age and condition of the individual subject to which the drug is to be administered.
[0074] In general, parenteral administration requires lower dosages than other administration methods that are more dependent on absorption. That being said, dosages for humans preferably comprise 0.0001 to 100 mg per kg of body weight. The desired dose may be presented as a single dose or multiple subdoses administered at appropriate intervals throughout the day.
[0075] The compounds according to the invention or their pharma- ceutically acceptable salts can be used as drugs in therapy.
[0076] Another aspect of the invention resides in the use of compounds having general formula I or a pharma- ceutically acceptable salt thereof for the therapeutic and / or prophylactic treatment of an ERRα-mediated disease or condition.In particular, the invention provides the use of compounds having general formula I or a pharma- ceutically acceptable salt thereof for the treatment of ERRα-mediated cancer.

[0445] i) To a solution of 3-methoxy-4-methyl-benzonitrile (11.55 g) and NBS (16.76 g) in ACN (550 mL) was added AIBN (1.29 g). The reaction mixture was heated to 85° C. and stirred for 4.5 h. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure and the resulting crude product was partitioned between water and EtOAc. The aqueous layer was extracted twice with EtOAc and the combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure.

[0822] Example 221 ERRα AlphaScreen Assay This assay was based on the knowledge that nuclear receptors interact with cofactors in ligand-dependent substrates. The site of interaction has been mapped to an LXXLL motif present in the co-activator sequence. Short peptide sequences containing the LXXLL motif mimic the behavior of full-length coactivators.
[0823] The ERRα alpha screen assay described herein relies on the interaction of a coactivator peptide with purified, bacterially expressed ERRα ligand binding domain (ERRα-LBD); upon ligand binding, the ERRα protein may undergo a conformational change, resulting in a loss of coactivator binding.
[0824] Compounds of the invention were tested for their ability to disrupt ERRα-LBD protein binding to coactivator peptides using AlphaScreen® technology (Perkin Elmer). ERRα-LBD protein was expressed in E. coli as a 6xHis Small Ubiquitin-like Modifier (SUMO) fusion. Bacterially expressed 6His-SUMO-ERRα-LBD protein was purified using affinity chromatography. All experiments were performed at room temperature in 384-well white non-binding plates (Greiner) using 50 mM Tris-HCl (pH 7.5), 100 mM NaCl, 0.1% Pluronic F-127, 0.05% BSA, and 5 mM TCEP as buffer. The final DMSO concentration in the assay was 1%. Compounds were assayed in triplicate and incubated with 0.81 nM ERRα-LBD protein, 10 μg / mL streptavidin donor beads and 10 μg / mL Ni-chelate acceptor beads at room temperature for 1 h, followed by incubation with 15 nM biotin-PGC1α-3 peptide (QRRPCSELLKYLTTNDDPP) corresponding to amino acids 202-220 for 2 h.
[0825] AlphaScreen signals were measured using an Envision Xcite plate reader (Perkin Elmer). Data were normalized and curve fitting analysis was performed in GraphPad Prism7 using a four-parameter dose-response fit.

[0831] A method was established to quantitatively screen the potency of compounds with inverse agonist activity against the nuclear receptor ERRα of human species. The assay allows intracellular screening of ERRα inverse agonists in SK-BR-3 cells using an over-expression construct encoding full-length ERRα and a reporter construct containing an ERRα response element (RE) and a luciferase gene for readout. The activity is expressed as a logIC50 value and can be used to determine the SAR of a compound family or to deselect compounds.
[0832] In this assay, reporter cells are obtained by transient co-transfection of the two constructs in SK-BR-3 cells using standard transfection techniques. The first construct contains the response element of the nuclear receptor ERRα (plasmid pLP2175, reporter construct ERRα-RE / luc2P, a cloned variant of ERRa_v2_synthRE, Switchgear Genomics, catalog number S900089). This sequence drives the transcription of a luciferase reporter gene in response to binding of the ERRα protein encoded by the second construct (plasmid pLP2124: full-length ERRα expression construct using pcDNA3.1 / Hygro(+) as background, Invitrogen catalog number V87020). The overexpressed full-length ERRα is constitutively active, and therefore the expression of luciferase is reduced by inverse agonists of the nuclear receptor ERRα.
[0833] The day after transfection, cells were seeded into 96-well plates, test compounds were added, and the plates were incubated overnight. Firefly luciferase activity was then quantified using a luciferase detection reagent and luminescence readout.
[0834] Detailed assay description Transfection is performed on pre-seeded SK-BR-3 cells in a T175 flask. Depending on the confluency of the transfected cells, one transfected T175 flask is sufficient to seed 3-4 MW96 plates the next day.
[0835] Two different media are used for cell treatment in this protocol: 1) Culture Medium, McCoy's 5a with Phenol Red (BioWhittaker supplier number 12-688F), 10% FBS, and Penstrep.; and 2) Assay Medium, Penstrep.; McCoy's 5a Medium Phenol Red Free (HyClone product code SH30270.01) with 2% Charcoal Stripped FBS and 1x Penstrep. Compound dilutions are prepared in Assay Medium.
[0836] Cells are seeded at least 2 days in advance to allow the cells to fully attach to the flask before transfection. On the day of transfection, cells should be 50-80% confluent.
[0837] SKBR3 cells were transfected with the transcriptional reporter construct pLP2175 and the ERRα expression construct pLP2124 (as described above).
[0838] 68 μL of Lipofectamine LTX transfection reagent (Invitrogen Catalog No. 15338-100) was added dropwise to 8.9 ml of Opti-MEM I Reduced Serum Medium (Gibco Catalog No. 51985-026) and incubated at room temperature for 5-20 minutes. 8.9 ml of this reagent mixture was added to 22 μg of pLP2175 + 22 μg of pLP2124 (1:1 ratio and 10 ml total volume) and incubated at room temperature for 25 minutes.
[0839] 10 min before adding the transfection mix to SKBR3 cells in a T175 flask, the medium was refreshed with 20 mL of medium, then 10 mL of the DNA-Opti-MEM-Lipofectamine mixture was gently added to the cells, followed by overnight (16-24 h) incubation at 37°C and 5% CO2.
[0840] To harvest SKBR3 cells from a T175 flask, the medium was first removed. The cells were then washed with Phosphate Buffered Saline (PBS) (Lonza), after which the PBS was removed. To detach the cells, 2 ml of TrypLE Express (Invitrogen) was added to the flask, followed by incubation at 37°C for 5 minutes. The flask was gently tapped until the cells were detached from the bottom. The cells were harvested in 8 mL of medium (McCoy's 5a, 10% FBS, penstrep) to achieve a single cell suspension. After cell counting, the cells were spun down at 300 g for 5 minutes. The cell pellet was then resuspended in 25,000 cells / 80 μL assay medium (McCoy's 5a phenol red-free, 2% charcoal-stripped FBS, penstrep.).
[0841] For compound screening, cells were harvested (as described above) and 80 μL of cell suspension (25,000 cells) was seeded per well into white, flat-bottom, tissue culture-treated, 96-well screening plates (Greiner).
[0842] Test compounds were diluted in three dilution steps starting from a 10 mM dimethyl sulfoxide (DMSO) stock solution. The first dilution step was a 12-point serial dilution of 4-fold in DMSO. These dilutions were further diluted 10-fold in phenol red-free assay medium containing 2% charcoal-stripped FBS and penstrep. The final step was a further 20-fold dilution in assay medium to obtain 5-fold concentrated dilutions with a DMSO concentration of 0.5%. As a final step, compound dilutions were diluted 5-fold in cell plates.
[0843] A DMSO dilution series was constructed with 12 concentrations, with final concentrations on the cell plate ranging from 10 μM to 2.4 fM.
[0844] The plates were incubated overnight (16-24 hours) at 37° C. and 5% CO2.
[0845] To read luciferase, luciferase reagent (BriteLite Plus, Perkin Elmer) was warmed to room temperature. 100 μL of 2.5-fold diluted BriteLite Plus reagent was added to each test well of the screening plate and incubated at room temperature for 5 min. Luciferase luminescence signals were measured using a Wallac Victor Microplate Reader (Perkin Elmer).
[0846] Half-maximal inhibitory concentration values (IC50) for test compounds were calculated from the luciferase signal using GraphPad Prism software (GraphPad Software). For completeness, multiple IC50 values for the same compound and cell line pair were annotated and the average pIC for each compound was calculated. 50 It was decided.
[0847] From the exemplified compounds of formula I, Examples 1, 8, 9, 15, 19, 24, 32, 33, 36, 40, 62, 68, 89, 91, 93, 96, 97, 98, 99, 100, 101, 102, 106, 107, 115, 119, 140, 142, 143, 144, 145, 146, 147, 149, 150, 155, 157, 159, 166, 169, 170, 174, 175, 176, 177, 178, 179, 186, 189, 192, 194, 196, 198, 200, 202, 207, 208, 211, 212, and 214 had an average pIC 50 The values were found to be 6.5 or higher.
[0848] Example 223 B16F10 melanoma syngeneic mouse model Example inhibitors 100, 191, 192, 194 and 196 were tested for their ability to inhibit tumor growth in the B16F10 melanoma syngeneic mouse model.
[0849] Cell lines and tumor models: Allograft model derived from the B16F10 melanoma cell line in C57BL / 6 mice.
[0850] Mouse B16F10 melanoma cells were supplied by the American Type Culture Collection (ATCC) (USA). Cells were cultured in DMEM (Invitrogen, Cat. No. 31600-034) supplemented with 10% FBS (Invitrogen, Cat. No. 10438-026) and 1% penicillin-streptomycin (Thermo Fisher Scientific, Cat. No. 15140-122). To establish allografts, cells were harvested by trypsinization when they reached approximately 70-80% confluence, and 100,000 B16F10 cells were suspended in 50 μL of serum-free medium and mixed with matrigel in a 1:1 ratio before being implanted subcutaneously into the dorsal right flank of mice using a 1 mL BD syringe attached to a 24-gauge needle.
[0851] B16F10 tumor grafts were measured 5 days after cell inoculation when they were palpable. After randomization of animals into different treatment groups, while maintaining tumor volume and number of animals, the mean tumor volume of each group remained the same between groups, with the mean tumor volume reaching approximately 58 mm. 3 Animals were dosed when they reached a dose of 0.01 mg / kg / day. Dosing was by mouth (per os, or po) once daily (quaque, or qd) on a per kilogram body weight basis.
[0852] Tumor size (length (l) and breadth (b)) was measured with calipers on the day animals were randomized based on tumor volume (day 1) and then three times a week until the end of the study. Tumor volume was calculated according to the formula b 2 * l * 0.52 (where l = length, b = width) was used (Dusan Djokovic et al., BMC Cancer, 2010, 10:641). Tumor growth inhibition was calculated after normalizing the tumor volume on a given day to the tumor volume on day 1.
[0853] The average tumor volume was 58 mm 3 When this was reached, administration of the test item was initiated.
[0854] Test article administration was performed until day 14, and tumor volume measurements were performed until day 13 to calculate percent tumor growth inhibition (TGI). The results of the study are listed in Table 1 below.
