Abstract
Description
Nitrogen-containing heterocyclic compounds with Nrf2 activation activity
[0001] The present invention relates to a nitrogen-containing heterocyclic compound, a salt thereof, or a solvate thereof having Nrf2 activation activity, and uses thereof. It also relates to a medicament and a pharmaceutical composition containing the compound or salt as an active ingredient.
[0002] Nrf2 is a regulatory factor for genes involved in various biological defenses and a transcription factor that is activated in response to oxidative stress. Under normal conditions, Nrf2 binds to Keap1, undergoes ubiquitination, and is degraded via the proteasome pathway. However, under stressful conditions, it is released from Keap1, avoiding degradation and translocating into the nucleus. Nrf2 then forms a heterodimer with a small Maf group factor and induces the transcription of downstream molecules by binding to antioxidant response elements (AREs).
[0003] Activation of Nrf2 exhibits a wide range of pharmacological effects, including antioxidant, anti-inflammatory, anti-fibrotic, and anti-apoptotic effects, and is thought to have a protective effect against various diseases. Specific examples of diseases include neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Friedreich's ataxia, and amyotrophic lateral sclerosis; pulmonary diseases such as idiopathic pulmonary fibrosis, acute respiratory distress syndrome, chronic obstructive pulmonary disease, pulmonary arterial hypertension, and asthma; renal diseases such as chronic kidney disease and acute kidney injury; ophthalmological diseases such as uveitis, glaucoma, and age-related macular degeneration; liver diseases such as non-alcoholic steatohepatitis; and immune / inflammatory diseases such as multiple sclerosis, rheumatoid arthritis, and ulcerative colitis (Non-Patent Documents 3 to 7). Clinical trials are currently being conducted on compounds that actually induce Nrf2 activation, such as bardoxolone methyl (CDDO-Me, Patent Document 1) for various chronic kidney diseases, and RTA-408 (omaveloxolone, Patent Document 2) for Friedreich's ataxia. Dimethyl fumarate (Patent Document 3) is used as a therapeutic agent for multiple sclerosis. However, these compounds covalently bind to Keap1. Concerns have been raised about the risk of heart failure due to interactions between the covalent binding site of bardoxolone methyl and non-target proteins (Non-Patent Document 8).
[0004] To date, compounds such as those described in Patent Document 4 have been reported as Nrf2 activators. However, they have not yet reached clinical development, and there is a need for the development of non-covalent Nrf2 activators that are expected to reduce interactions with non-target proteins (Non-Patent Documents 1 to 3).

Examples of commonly used dosage forms include liquid pharmaceutical preparations (liquids) such as injections, suspensions, emulsions, and eye drops, and solid pharmaceutical preparations (solid preparations) such as tablets, powders, fine granules, granules, coated tablets, capsules, dry syrups, lozenges, and suppositories, but are not limited thereto.
[0159] For example, to prepare a liquid formulation, a pharmacologically acceptable carrier or vehicle, specifically, pharmaceutically acceptable additives commonly used in the field of pharmaceutical formulations, such as sterile water, physiological saline, vegetable oil, emulsifier, suspending agent, surfactant, stabilizer, flavoring agent, excipient, vehicle, preservative, binder, etc., are added in appropriate combination to the compound represented by formula (1) of the present invention, or a salt thereof, or a solvate thereof, and then the mixture is mixed to form a unit dose required for generally accepted pharmaceutical practice. Alternatively, a solid formulation prepared for liquid formulation can be dissolved as needed by adding an appropriate solvent, such as sterile water or physiological saline, before administration, and then used for administration.
[0160] Such liquid preparations can also be used parenterally, for example, in the form of a sterile solution or suspension injection in water or other pharmaceutically acceptable liquid. For example, they can be formulated by appropriately combining them with pharmacologically acceptable carriers or vehicles, specifically, sterile water, physiological saline, vegetable oils, emulsifiers, suspending agents, surfactants, stabilizers, flavoring agents, excipients, vehicles, preservatives, binders, etc., and blending them in a unit dosage form required for generally accepted pharmaceutical practice. Specific examples of carriers include light anhydrous silicic acid, lactose, crystalline cellulose, mannitol, starch, carmellose calcium, carmellose sodium, hydroxypropyl cellulose, hydroxypropyl methylcellulose, polyvinyl acetal diethylaminoacetate, polyvinylpyrrolidone, gelatin, medium-chain fatty acid triglycerides, polyoxyethylene hydrogenated castor oil 60, sucrose, carboxymethylcellulose, cornstarch, inorganic salts, etc. The amount of active ingredient in these preparations is such that an appropriate dose within the indicated range can be obtained. Sterile compositions for injection can be formulated according to conventional pharmaceutical practice using a vehicle such as distilled water for injection.
[0161] Examples of aqueous solutions for injection include isotonic solutions containing physiological saline or other adjuvants, such as D-sorbitol, D-mannose, D-mannitol, and sodium chloride, and may be used in combination with an appropriate solubilizing agent, such as alcohol, specifically ethanol, polyalcohols such as propylene glycol and polyethylene glycol, or nonionic surfactants such as Polysorbate 80 (registered trademark) and HCO-50.
[0162] Examples of oily liquids include sesame oil and soybean oil, and they may be used in combination with solubilizing agents such as benzyl benzoate and benzyl alcohol. They may also contain buffers such as phosphate buffer and sodium acetate buffer, soothing agents such as procaine hydrochloride, stabilizers such as benzyl alcohol, phenol, and antioxidants. The prepared injection solution is usually filled into suitable ampoules.
[0163] For example, to produce a solid preparation, an excipient and, if necessary, pharmaceutically acceptable additives commonly used in the field of pharmaceutical preparations such as a binder, a disintegrant, a lubricant, a colorant, and a flavoring agent are added in appropriate combination to the compound represented by formula (1) of the present invention, or a salt thereof, or a solvate thereof, and then the mixture is made into tablets, powders, fine granules, granules, coated tablets, capsules, dry syrup, troches, suppositories, etc. by a conventional method.
[0164] Examples of pharmaceutically acceptable additives used in such solid preparations include animal and vegetable oils such as soybean oil, beef tallow, and synthetic glycerides; hydrocarbons such as liquid paraffin, squalane, and solid paraffin; ester oils such as octyldodecyl myristate and isopropyl myristate; higher alcohols such as cetostearyl alcohol and behenyl alcohol; silicone resins; silicone oils; surfactants such as polyoxyethylene fatty acid esters, sorbitan fatty acid esters, glycerin fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene hydrogenated castor oil, and polyoxyethylene polyoxypropylene block copolymers; water-soluble polymers such as hydroxyethyl cellulose, polyacrylic acid, carboxyvinyl polymers, polyethylene glycol, polyvinylpyrrolidone, and methylcellulose; lower alcohols such as ethanol and isopropanol; polyhydric alcohols such as glycerin, propylene glycol, dipropylene glycol, and sorbitol; sugars such as lactose, lactose hydrate, fructose, and sucrose; inorganic powders such as silicic anhydride, aluminum magnesium silicate, and aluminum silicate; and purified water.
[0165] Examples of excipients include sugars (e.g., lactose, lactose hydrate, fructose, sucrose, etc.), sugar alcohols (e.g., mannitol, etc.), starches (corn starch, potato starch, wheat starch, rice starch, partially pregelatinized starch, pregelatinized starch, etc.), celluloses (e.g., crystalline cellulose), inorganic salts (e.g., calcium silicate, anhydrous calcium hydrogen phosphate, precipitated calcium carbonate, etc.), etc.
[0166] Examples of binders include polyvinyl alcohol, polyvinyl ether, methyl cellulose, ethyl cellulose, gum arabic, tragacanth, gelatin, shellac, hydroxypropylmethyl cellulose, hydroxypropyl cellulose, polyvinylpyrrolidone, polypropylene glycol-polyoxyethylene block polymers, and the like.
[0167] Examples of disintegrants include croscarmellose sodium, carmellose sodium, hydroxypropyl cellulose, carmellose, carmellose calcium, methylcellulose, crystalline cellulose, sodium lauryl sulfate, povidone, and polysorbate.
[0168] Examples of lubricants include magnesium stearate, calcium stearate, talc, sucrose fatty acid esters, sodium stearyl fumarate, and hardened oils.
[0169] Coloring agents that are permitted to be added to pharmaceuticals are used, and flavoring agents include cocoa powder, peppermint, aromatic powder, peppermint oil, borneol, cinnamon powder, etc.
[0170] Of course, these tablets and granules may be coated with sugar or other suitable coatings as necessary. When producing liquid preparations such as syrups and injection preparations, the compound of the present invention or a pharmacologically acceptable salt thereof is formulated in a conventional manner by adding a pH adjuster, a solubilizer, an isotonicity agent, and, if necessary, a solubilizer, a stabilizer, etc.
[0171] The administration is preferably parenteral, but the administration method is not limited to parenteral administration. Specific examples of parenteral administration include injections, intranasal administrations, pulmonary administrations, transdermal administrations, etc. Examples of injections include intravenous injections, intramuscular injections, intraperitoneal injections, subcutaneous injections, etc., which can be used for systemic or local administration.
[0172] Furthermore, the administration method can be selected appropriately depending on the patient's age and symptoms. The dosage of a pharmaceutical composition containing the compound represented by formula (1) of the present invention, or a salt thereof, or a solvate thereof, produced by the method of the present invention, can be selected, for example, from the range of 0.0001 mg to 1000 mg per kg of body weight per administration. Alternatively, the dosage can be selected, for example, from the range of 0.001 to 100,000 mg / body weight per patient, but is not necessarily limited to these values. The dosage and administration method vary depending on the patient's weight, age, symptoms, etc., but can be appropriately selected by those skilled in the art.
[0173] In some embodiments, the compounds of the present invention can be used to activate Nrf2 or to inhibit Keap1 and activate Nrf2.
