Description

[Technical Field]

[0001] (Priority application) This application claims priority to U.S. Provisional Patent Application No. 63 / 491.473, filed on 21 March 2023, which is incorporated herein by reference.

[0002] (Field of invention) This technical field generally relates to compounds, compositions, and their uses in the treatment of disorders and conditions in which inhibition of acid-sensing ion channels (also known as ASICs) is indicated. For example, this application relates to substituted thiophene-condensed cyclohexanone derivatives, pharmaceutical compositions containing the same, and their use as ASIC inhibitors. [Background technology]

[0003] Since the discovery of acid-sensitive ion channels (ASICs) in 1997, the importance of neurons and other non-neuronal cells in health has become extremely important. ASICs play a crucial role in mediating pain, and their activity contributes to diseases such as stroke, inflammation, arthritis, cancer, and migraines.

[0004] ASICs are permeable to Na+ ions (and other cations), are activated by low extracellular pH, and are widely expressed in the central nervous system (CNS) and peripheral nervous system (PNS). ASICs are formed from homotrimeric and heterotrimeric assemblies of subunits including ASIC1a, ASIC1b, ASIC2a, ASIC2b, and ASIC3. ASIC1a is expressed in both the PNS and CNS, while ASIC1b is expressed in the PNS.

[0005] Tissue damage and inflammation can lead to acidosis, and acidification is considered a significant contributing factor to associated pain. The literature shows that ASIC inhibitors can alleviate pain in a variety of clinical conditions. Furthermore, because they have different mechanisms of action, ASIC antagonists may offer a new treatment option for patients who do not benefit from or cannot tolerate the adverse side effects of current analgesics.

[0006] Therefore, developing novel small molecule inhibitors specific to ASICs is important to provide further useful therapeutic agents for treating ASIC-related disorders or conditions such as pain. [Overview of the project]

[0023] general definition All technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art in which this technology pertains. For convenience, the meanings of specific terms and phrases used herein are provided below.

[0024] To the extent that definitions of terms in publications, patents, and patent applications incorporated herein by reference conflict with the definitions set forth herein, the definitions herein shall prevail. Section headings used herein are for structural purposes only and should not be construed as limiting the subject matter disclosed.

[0025] The terms used herein are intended solely to describe and not to limit specific embodiments. Note that the singular forms “a,” “an,” and “the” also include the plural form unless the context clearly indicates otherwise. Thus, for example, a reference to a composition containing a “compound” also intends to include a mixture of two or more compounds. Also note that the term “or” is generally used to include “and / or” unless the context clearly indicates otherwise. Furthermore, the terms “including,” “includes,” “having,” “has,” “with,” or variations thereof, are intended to be as comprehensive as the term “comprising,” insofar as they are used in either the detailed description and / or the claims.

[0026] The term "approximately" means that a particular value is within an acceptable margin of error, as determined by those skilled in the art, and this depends in part on how the value is measured or determined, i.e., on the limits of the measuring system. For example, "approximately" may mean a standard deviation of 1 or more than 1, depending on the practice in the art. Alternatively, "approximately" may mean a range of up to 20%, preferably up to 10%, more preferably up to 5%, and even more preferably up to 1% of a given value. Or, particularly with respect to biological systems or processes, the term may mean within one order of magnitude of a value, preferably up to five times, and more preferably up to two times. Where a particular value is described in this application and claims, unless otherwise specified, the term "approximately" should be assumed to mean within an acceptable margin of error for that particular value.

Heteroaryl groups may include, but are not limited to, thienyl, furanyl (furyl), pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiazolyl, benzofuranyl, dibenzofuranyl, benzimidazolyl, benzothiazolyl, benzothienyl (benzothiophenyl), benzoxazolyl, isothiazolyl, thiadiazolyl, pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, triazinyl, flupyridinyl, indazolyl, isoindolyl, indolidinyl, purinyl, quinolyl (quinolinyl), isoquinolyl (isoquinolinyl), acridinyl, sinnolinyl, quinazolinyl, naphthilidinyl, carbazolyl, phenantridinyl, phenazinyl, phenothiazinyl, phenoxazinyl, and pteridinyl. A heteroaryl group can be bonded to its pendant group with any heteroatom or carbon atom that results in a chemically stable structure.

[0045] As used herein, the term “partially unsaturated heterocyclic group” refers to a carbocyclic ring system that contains at least one double bond between ring atoms but is not entirely aromatic and contains at least one heteroatom. “Partially unsaturated heterocyclic groups” can be monocyclic, dicyclic, or tricyclic and are intended to encompass ring systems having one or more unsaturated sites. In some embodiments, a partially unsaturated heterocyclic group may include a polycyclic ring system in which at least one ring is aromatic but at least one other ring is not. For example, a partially unsaturated heterocyclic group may include an aryl fused with a heterocycloalkyl, a heteroaryl fused with a cycloalkyl, or a heteroaryl fused with a heterocycloalkyl, each of which may be monocyclic or bicyclic. In some embodiments, a partially unsaturated heterocyclic group may contain 7 to 14 carbon atoms, e.g., 7 to 10 carbon atoms or 8 to 14 carbon atoms. For example, a "7- to 10-membered partially unsaturated heterocyclic group" contains 7 to 10 atoms in the heterocyclic portion, by counting the total number of carbon atoms and heteroatoms. In some embodiments, a partially unsaturated heterocyclic group may contain 1 to 4 heteroatoms. A partially unsaturated heterocyclic group can be bonded to its pendant group with any heteroatom or carbon atom that results in a chemically stable structure. Non-restrictive examples of partially unsaturated heterocyclic groups include pyrazolinyl, imidazolinyl, 1,2,3,6-tetrahydropyridinyl, 2-pyrrolinyl, 3-pyrrolinyl, 2H-pyranyl, 4H-pyranyl, dihydropyranyl, dihydrothienyl, dihydrofuranyl, quinolidinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, 1,3-benzodioxolyl, chromanyl, clomenyl, indolinyl, quinolonyl, isoquinolonyl, oxazepinyl, diazepinyl, thiazepinyl, phthalazinyl, quinoxalinyl, pyrido[2,3-b]-1,4-oxazine-3(4H)-one,

[0046] [ka] For example, when used in reference to the ring atoms of a heterocyclic group, the term "nitrogen" includes substituted nitrogen. For example, in a saturated or partially unsaturated ring having 1 to 3 heteroatoms selected from oxygen, sulfur, and nitrogen, nitrogen can be N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in pyrrolidinyl), or NR0 (as in N-substituted pyrrolidinyl).

[0047] As used herein, the term “partially unsaturated carbocyclic group” refers to a carbocyclic ring system that contains at least one double bond between ring atoms but is not entirely aromatic. “Partially unsaturated carbocyclic group” is intended to encompass ring systems that contain only carbon atoms within the ring, which may be monocyclic, dicyclic, or tricyclic and have one or more unsaturated sites. In some embodiments, a partially unsaturated carbocyclic group may include a polycyclic ring system in which at least one ring is aromatic but at least one other ring is not aromatic. For example, a partially unsaturated heterocyclic group may include an aryl fused with a cycloalkyl, each of which may be monocyclic or bicyclic. In some embodiments, a partially unsaturated carbocyclic group may contain 7 to 14 carbon atoms, such as 7 to 10 carbon atoms or 8 to 14 carbon atoms. For example, an “8- to 14-membered partially unsaturated carbocyclic group” contains 8 to 14 carbon atoms in the cyclic portion. Partially unsaturated carbocyclic groups can have their pendant groups bonded to any carbon atom that results in a chemically stable structure. Non-limiting examples of partially unsaturated carbocyclic groups include:

[0048] [ka] These are some examples.

[0049] As described herein, various chemical groups present in the compounds herein, for example, any of the groups defined above, may be optionally substituted.

[0313] In some embodiments, therapeutically effective amounts of the compounds defined herein may be administered to a patient or subject alone or in mixture with pharmaceutically acceptable carriers, diluents, or excipients.

[0314] The compositions described herein may be administered orally, parenterally, by inhalation spray, topically, rectally, rectally, nasally, buccally, vaginally, or via an implanted reservoir. As used herein, the term “parenterally” includes subcutaneous, intravenous, intramuscular, intra-articular, intra-sacral, intrasternal, intrathecal, intrahepatic, intrafocal, and intracranial injection or infusion techniques. Other modes of administration include intradermal or transdermal administration.

[0315] Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compound, the liquid dosage form may contain, for example, inert diluents commonly used in the art, such as water or other solvents, solubilizers and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (especially cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil, and sesame oil), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycol, and fatty acid esters of sorbitan, and mixtures thereof. In addition to inert diluents, the oral composition may also contain excipients such as wetting agents, emulsifiers and suspending agents, sweeteners, flavoring agents, and fragrances.

[0316] Preparations for injection, such as sterile aqueous or oily suspensions for injection, can be formulated according to well-known techniques using suitable dispersants or wetting agents and suspending agents. Sterile preparations for injection may be sterile injection solutions, suspensions, or emulsions in non-toxic, parenterally acceptable diluents or solvents, such as solutions in 1,3-butanediol. Acceptable carriers and solvents that can be used are water, Ringer's solution, USP, and isotonic sodium chloride solution. In addition, sterile fixatives have traditionally been used as solvents or suspension media. For this purpose, any mild fixative containing synthetic monoglycerides or diglycerides may be used. Furthermore, fatty acids such as oleic acid are also used in preparations for injection.

[0317] Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating a sterilizing agent in the form of a sterile solid composition that can be dissolved or dispersed in sterile water or other sterile injectable media before use.

[0318] To extend the effects of the compound being administered, it is often desirable to delay the absorption of the compound from subcutaneous or intramuscular injection. This can be achieved by using a liquid suspension of a low-water-soluble crystalline or amorphous substance. The absorption rate of the compound depends on its dissolution rate, which in turn may depend on the crystal size and crystalline form. Alternatively, delayed absorption of parenterally administered compound forms is achieved by dissolving or suspending the compound in an oil carrier. Injectable depot forms are prepared by forming a matrix of microencapsulated compounds in biodegradable polymers such as polylactide-polyglycolide. Depending on the compound-to-polymer ratio and the properties of the specific polymer used, the rate of compound release can be controlled.

[0319] Other examples of biodegradable polymers include poly(orthoester) and poly(anhydride). Depot injection formulations are also prepared by encapsulating the compound in liposomes or microemulsions compatible with body tissues.

[0320] Compositions for rectal or vaginal administration are preferably suppositories that can be prepared by mixing the compounds of this specification with suitable non-irritating excipients or carriers, such as cocoa butter, polyethylene glycol, or suppository wax, which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectal or vaginal cavity to release the active compound.

[0321] Examples of solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier, such as sodium citrate or dicalcium phosphate, and / or a) fillers or bulking agents such as starch, lactose, sucrose, glucose, mannitol, and silicic acid; b) binders such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone (PVP), sucrose, and acacia; c) humectants such as glycerol; d) disintegrants such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; e) dissolution retarders such as paraffin; f) absorption enhancers such as quaternary ammonium compounds; g) wetting agents such as cetyl alcohol and glycerol monostearate; h) absorbents such as kaolin and bentonite clay; i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycol, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets, and pills, the dosage form may include a buffering agent.

[0322] Similar types of solid compositions can also be used as fillers in soft and rigid gelatin capsules, using excipients such as lactose or milk sugar and high molecular weight polyethylene glycol. Solid dosage forms of tablets, sugar-coated tablets, capsules, pills, and granules can be prepared using coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical field. They may optionally contain opacifiers, and they may be compositions that optionally release only the active ingredient, or preferentially the active ingredient, in a delayed manner in a specific part of the intestinal tract. Examples of embedding compositions that can be used include polymers and waxes. Similar types of solid compositions can also be used as fillers in soft and rigid gelatin capsules, using excipients such as lactose or milk sugar and high molecular weight polyethylene glycol.

[0323] The compounds provided may also be in microencapsulated form having one or more excipients as described above. Solid dosage forms of tablets, sugar-coated tablets, capsules, pills, and granules may be prepared using coatings and shells such as enteric coatings, controlled-release coatings, and other coatings well known in the pharmaceutical field. In such solid dosage forms, the active compound may be mixed with at least one inert diluent, e.g., sucrose, lactose, or starch. Such dosage forms may also include additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids, e.g., magnesium stearate and microcrystalline cellulose, as is common practice. In the case of capsules, tablets, and pills, the dosage form may also include buffers. These may optionally contain opacifiers, and may be compositions that optionally release only the active ingredient, or preferentially the active ingredient, in a delayed manner in a specific part of the intestinal tract. Examples of embedding compositions that can be used include polymeric substances and waxes.

[0324] Dosage forms for topical or transdermal administration of the compounds described herein include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants, or patches. The active ingredients are mixed under sterile conditions with a pharmaceutically acceptable carrier and, if necessary, any required preservatives or buffers. Ophthalmic formulations, ear drops, and eye drops are also intended to be within the scope of this specification. Furthermore, this specification intends for the use of transdermal patches, which have the additional advantage of providing controlled delivery of the compounds to the body. Such dosage forms can be prepared by dissolving or dispersing the compounds in a suitable medium. Absorption enhancers can also be used to increase the flow of the compounds through the skin. The rate can be controlled by providing a rate-controlled membrane or by dispersing the compounds in a polymer matrix or gel.

[0325] The pharmaceutically acceptable compositions provided herein may also be administered by nasal aerosol or inhalation. Such compositions may be prepared in accordance with techniques well known in the field of pharmaceutical formulations and may be prepared as solutions in physiological saline using benzyl alcohol or other suitable preservatives, absorption enhancers to enhance bioavailability, fluorocarbons, and / or other conventional solubilizers or dispersants.

[0326] The pharmaceutically acceptable compositions provided herein can be formulated for oral administration. Such formulations may be administered with or without food. In some embodiments, the pharmaceutically acceptable compositions of this disclosure are administered without food. In other embodiments, the pharmaceutically acceptable compositions of this disclosure are administered with food.

[0327] The amount of the provided compound that can be combined with a carrier substance to produce a single-dosage-form composition varies depending on the patient being treated and the specific mode of administration. The provided compositions can be formulated so that inhibitors in doses of 0.01 to 100 mg / kg body weight / day can be administered to patients receiving these compositions.

[0328] It should also be understood that specific dosages and treatment regimens for any particular patient depend on a variety of factors, including age, weight, general health, sex, diet, administration time, excretion rate, drug combinations, the judgment of the treating physician, and the severity of the specific disorder being treated. The amount of compound provided in a composition also depends on the specific compound in the composition.

[0329] The compounds or compositions described herein may be administered in any amount and via any route of administration that is effective in treating or alleviating the disorder or the severity of the disorder as intended herein. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the specific drug, and its mode of administration. The compounds provided are preferably formulated in unit dosage forms for ease of administration and uniformity of dosage. As used herein, the term “unit dosage form” refers to a physically distinct unit of the drug appropriate for the patient being treated. However, it will be understood that the total daily dose of the compounds and compositions disclosed herein will be determined by the attending physician within the bounds of sound medical judgment. A specific effective dose level for any particular patient or organism depends on a variety of factors, including the disorder and its severity being treated, the activity of the specific compound used, the specific composition used, the patient’s age, weight, general health, sex, and diet, the timing of administration, route of administration, and excretion rate of the specific compound used, the duration of treatment, drugs used in combination with or concurrently with the specific compound used, and similar factors well known in the medical field.

[0330] The pharmaceutically acceptable compositions of this disclosure may be administered to humans and other animals orally, rectally, parenterally, intracisionally, vaginally, intraperitoneally, topically (such as in powder, ointment, or drops), buccally, or as a nasal spray, depending on the severity of the infection being treated. In certain embodiments, the compounds provided may be administered orally or parenterally once or twice a day at a dosage level of about 0.01 mg / kg to about 50 mg / kg of the subject's body weight per day, preferably about 1 mg / kg to about 25 mg / kg, to obtain the desired therapeutic effect.

[0331] After the patient's condition has improved, a maintenance dose of the compound or composition specified herein may be administered as needed. Thereafter, the dose, frequency, or both of the administrations may be reduced as a function of the symptoms to a level at which the improved condition is maintained, and treatment should be discontinued when the symptoms have been relieved to the desired level. However, the patient may require intermittent treatment on a long-term basis in response to any recurrence of the disorder symptoms.

[0332] However, it will be understood that the total daily dose of the compounds and compositions described herein should be determined by the attending physician within the bounds of sound medical judgment. A specific inhibitory dose for any particular patient depends on a variety of factors, including the disorder being treated and its severity, the activity of the specific compound used, the specific composition used, the patient's age, weight, general health, sex, and diet, the timing of administration, route of administration, and excretion rate of the specific compound used, the duration of treatment, any drugs used in combination with or concurrently with the specific compound used, and similar factors well known in the medical field.

[0333] The total daily inhibitory dose of the compounds specified herein, administered to a subject in single or divided doses, may be, for example, 0.01 to 50 mg / kg body weight, or more than 0.1 to 25 mg / kg body weight. A single-dose composition may contain an amount or a fraction thereof that constitutes a daily dose. In one embodiment, a therapeutic regimen according to this specification involves administering to a patient requiring such treatment about 10 mg to about 1000 mg of the compounds specified herein per day in single or multiple doses.
