Description

POTASSIUM CHANNEL MODULATORS BACKGROUND

[0001] Among the ion channels, potassium channels are the largest and most diverse, being found in a variety of animal cells such as nervous, muscular, glandular, immune, reproductive, and epithelial tissue. These channels allow the flow of potassium in and / or out of the cell under certain conditions. These channels are regulated, e.g., by calcium sensitivity, voltage-gating, second messengers, extracellular ligands, and ATP-sensitivity.

[0002] Dysfunction of potassium channels, as well as other ion channels, generates loss of cellular control and results in altered physiological functioning and disease conditions.

[0003] Because of their ability to modulate ion channel function and / or regain ion channel activity in acquired or inherited channel opathies, potassium channel modulators are being used in the pharmacological treatment of a wide range of pathological diseases and have the potential to address an even wider variety of therapeutic indications.

[0004] The small conductance calcium-activated potassium channels (SK channel) are a subfamily of Ca<com:Sup>2+< / com:Sup>-activated K<com:Sup>+< / com:Sup> channels and the SK channel family contains 4 members - SK1, SK2, SK3, and SK4 (often referred to as intermediate conductance). The physiological roles of the SK channels have been especially studied in the nervous system, where for example they are key regulators of neuronal excitability and of neurotransmitter release, and in smooth muscle, where they are crucial in modulating the tone of vascular, broncho- tracheal, urethral, uterine or gastro-intestinal musculature.

[0005] Given these implications, small molecule modulators of potassium ion channels could have potentially powerful influence in the modulation and control of numerous consequences of a variety of conditions. SUMMARY

[0006] Disclosed are compounds and pharmaceutically acceptable salts thereof, and pharmaceutical compositions thereof, which are useful in the treatment of diseases associated with the modulation of ion channels, such as potassium ion channels. (See e.g., Table 2). Such compounds include those of structural Formula I: [Image disponible dans le document PDF, Image available in the PDF document] ) or a pharmaceutically acceptable salt thereof, wherein each of R<com:Sup>1< / com:Sup>, R<com:Sup>3< / com:Sup>, R<com:Sup>5< / com:Sup>, R<com:Sup>4a< / com:Sup>, R<com:Sup>4b< / com:Sup>, X<com:Sup>1< / com:Sup>, X<com:Sup>2< / com:Sup>, and A are defined and described herein.

[0007] Compounds described herein, and pharmaceutically acceptable compositions thereof, are useful for treating a variety of diseases, disorders or conditions, associated with the modulation of potassium channels. Such diseases, disorders, or conditions include those described herein. BRIEF DESCRIPTION OF THE FIGURES

Compounds and Definitions

[0010] The terms "halo" and "halogen" as used herein refer to an atom selected from fluorine (fluoro, -F), chlorine (chloro, -Cl), bromine (bromo, -Br), and iodine (iodo, -I).

[0011] The term "alkyl" used alone or as part of a larger moiety, such as "alkoxy", "haloalkyl", "aralkyl", "heteroaralkyl" and the like, means saturated straight-chain or branched monovalent hydrocarbon radical. Unless otherwise specified, an alkyl group typically has 1-6 carbon atoms, i.e., <com:Math><semantics>(C1−C6)<annotation encoding="application / x-tex">(C_1-C_6)< / annotation>< / semantics>< / com:Math> alkyl. As used herein, a "<com:Math><semantics>(C1−C6)<annotation encoding="application / x-tex">(C_1-C_6)< / annotation>< / semantics>< / com:Math> alkyl" group is means a radical having from 1 to 6 carbon atoms in a linear or branched arrangement.

[0012] The term "haloalkyl" includes mono, poly, and perhaloalkyl groups where the halogens are independently selected from fluorine, chlorine, bromine, and iodine.

[0013] "Alkoxy means an alkyl radical attached through an oxygen linking atom, represented by <com:Math><semantics>−O<annotation encoding="application / x-tex">-O< / annotation>< / semantics>< / com:Math>-alkyl. For example, "<com:Math><semantics>(C1−C4)<annotation encoding="application / x-tex">(C_1-C_4)< / annotation>< / semantics>< / com:Math>alkoxy" includes methoxy, ethoxy, proproxy, and butoxy.

[0014] The term "aryl" used alone or as part of a larger moiety as in "aralkyl", "aralkoxy", or "aryloxyalkyl", refers to an aromatic monocyclic or bicyclic carbon ring system having, unless otherwise specified, a total of 6 to 14 ring members. The term "aryl" may be used interchangeably with the term "aryl ring", "aryl group", "aryl moiety," or "aryl radical". Also included within the scope of the term "aryl", as it is used herein, is a group in which an aromatic carbon ring is fused to one or more carbocyclyl rings, e.g., tetrahydronaphthalenyl. In certain embodiments of the present disclosure, "aryl" refers to an aromatic ring system which includes, but is not limited to, phenyl (abbreviated as "Ph"), naphthyl and the like. It will be understood that when specified, optional substituents on an aryl group (e.g., in the case of an optionally substituted aryl or aryl which is optionally substituted) may be present on any substitutable position, i.e., any ring carbon substituted with hydrogen.

[0015] The term "carbocyclyl" (also referred to herein as "carbocycle" or "cycloaliphatic", as used herein, means a monocyclic, bicyclic (e.g., a bridged or spiro bicyclic ring), polycyclic (e.g., tricyclic), or fused hydrocarbon ring system that is completely saturated or that contains one or more units of partial unsaturation, but where there is no aromatic ring. Cycloalkyl is a completely saturated carbocycle. Monocyclic carbocyclyl groups include, without limitation, cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, cyclohexenyl, cycloheptyl, cycloheptenyl, and cyclooctyl. Bridged bicyclic carbocyclyl groups include, without limitation, bicyclo[3.2.1]octane, bicyclo[2.2.1]heptane, bicyclo[3.1.0]hexane, and the like. Spiro bicyclic carbocyclyl groups include, e.g., spiro[3.6]decane, spiro[4.5]decane, and the like. Fused carbocyclyl rings include, e.g., decahydronaphthalene, octahydropentalene, and the like. It will be understood that when specified, optional substituents on a carbocyclyl (e.g., in the case of an optionally substituted carbocyclyl or carbocyclyl which is optionally substituted) may be present on any substitutable position and, include, <com:Math><semantics>e.g.<annotation encoding="application / x-tex">e.g.< / annotation>< / semantics>< / com:Math>, the position at which the carbocyclyl group is attached.

[0016] The term "heteroaryl" used alone or as part of a larger moiety as in "heteroarylalkyl", "heteroarylalkoxy", or "heteroarylaminoalkyl", refers to a 5-10 -membered aromatic radical containing 1-4 heteroatoms selected from N, quaternary ammonium cation, O, and S, and includes, for example, thienyl, furanyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiazolyl, isothiazolyl, thiadiazolyl, pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, indolizinyl, purinyl, naphthyridinyl, and pteridinyl. The term "heteroaryl" may be used interchangeably with the terms "heteroaryl" ring", "heteroaryl group", or "heteroaromatic". Nonlimiting examples include indolyl, indazolyl, benzimidazolyl, benzthiazolyl, pyrrolopyridinyl, quinolyl, quinazolinyl, and quinoxalinyl. It will be understood that when specified, optional substituents on a heteroaryl group may be present on any substitutable position (carbon and nitrogen).

[0017] The term "heterocyclyl" means a 3-12 membered (e.g., a 4-, 5-, 6- and 7- membered) saturated or partially unsaturated heterocyclic ring containing 1 to 4 heteroatoms independently selected from N, O, and S. It can be mononcyclic, bicyclic (e.g., a bridged, fused, or spiro bicyclic ring), or tricyclic. The terms "heterocycle", "heterocyclyl", "heterocyclyl ring", "heterocyclic group", "heterocyclic moiety", and "heterocyclic radical", are used interchangeably herein. A heterocyclyl ring can be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure. Examples of such saturated or partially unsaturated heterocyclic radicals include, without limitation, tetrahydrofuranyl, tetrahydrothienyl, terahydropyranyl, pyrrolidinyl, pyridinonyl, pyrrolidonyl, piperidinyl, oxazolidinyl, piperazinyl, dioxanyl, dioxolanyl, morpholinyl, dihydrofuranyl, dihydropyranyl, dihydropyridinyl, tetrahydropyridinyl, dihydropyrimidinyl, 3- azabicyclo[3.1.0]hexanyl, 2-oxa-6-azaspiro[3.3]heptanyl, 1-azaspiro[4.5]decane, and tetrahydropyrimidinyl. The term "heterocyclyl" also includes, e.g., unsaturated heterocyclic radicals fused to another unsaturated heterocyclic radical or aryl or heteroaryl ring, such as for example, tetrahydronaphthyridine, indolinone, dihydropyrrolotriazole, imidazopyrimidine, quinolinone, dioxaspirodecane. It will also be understood that when specified, optional substituents on a heterocyclyl group may be present on any substitutable position and, include, e.g., the position at which the heterocyclyl is attached (e.g., in the case of an optionally substituted heterocyclyl or heterocyclyl which is optionally substituted).

[0018] The term "spiro" refers to two rings that share one ring atom (e.g., carbon).

[0019] The term "fused" refers to two rings that share two adjacent ring ring atoms.

[0020] The term "bridged" refers to two rings that share at least three ring atoms.

[0021] As described herein, compounds herein may contain "optionally substituted" moieties. Unless otherwise indicated, an "optionally substituted" group may have a suitable substituent that results in the formation of stable or chemically feasible compounds.

[0024] As used herein the terms "subject" and "patient" may be used interchangeably, and means a mammal in need of treatment, e.g., companion animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, pigs, horses, sheep, goats and the like) and laboratory animals (e.g., rats, mice, guinea pigs and the like). Typically, the subject is a human in need of treatment.

[0025] The terms "treatment," "treat," and "treating" refer to reversing, alleviating, reducing the likelihood of developing, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed, i.e., therapeutic treatment. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and / or in light of genetic or other susceptibility factors), i.e., prophylactic treatment. Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.

[0026] The term "effective amount" or "therapeutically effective amount" includes an amount of a compound described herein that will elicit a biological or medical response of a subject.

[0027] Certain of the disclosed compounds may exist in various stereoisomeric forms. Stereoisomers are compounds that differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. "Enantiomer" means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that contain two or more asymmetrically substituted carbon atoms. "Geometric isomer" are stereoisomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a carbocyclyl ring, or to a bridged bicyclic system.

[0028] "Racemate" or "racemic mixture" means a compound of equimolar quantities of two enantiomers, wherein such mixtures exhibit no optical activity, i.e., they do not rotate the plane of polarized light.

[0029] The compounds of the invention may be prepared as individual enantiomers by either enantio-specific synthesis or resolved from an enantiomerically enriched mixture. Conventional resolution techniques include forming the salt of a free base of each isomer of an enantiomeric pair using an optically active acid (followed by fractional crystallization and regeneration of the free base), forming the salt of the acid form of each enantiomer of an enantiomeric pair using an optically active amine (followed by fractional crystallization and regeneration of the free acid), forming an ester or amide of each of the enantiomers of an enantiomeric pair using an optically pure acid, amine or alcohol (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an enantiomeric mixture of either a starting material or a final product using various well known chromatographic methods.

[0030] When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight pure relative to all of the other stereoisomers. Percent by weight pure relative to all of the other stereoisomers is the ratio of the weight of one stereoisiomer over the weight of the the other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight optically pure. Percent optical purity by weight is the ratio of the weight of the enantiomer over the weight of the enantiomer plus the weight of its optical isomer.

[0031] When the stereochemistry of a disclosed compound is named or depicted by structure, and the named or depicted structure encompasses more than one stereoisomer (e.g., as in a diastereomeric pair), it is to be understood that one of the encompassed stereoisomers or any mixture of the encompassed stereoisomers are included. It is to be further understood that the stereoisomeric purity of the named or depicted stereoisomers at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight pure relative to all of the other stereoisomers. The stereoisomeric purity in this case is determined by dividing the total weight in the mixture of the stereoisomers encompassed by the name or structure by the total weight in the mixture of all of the stereoisomers.

[0032] When a disclosed compound is named or depicted by structure without indicating the stereochemistry, and the compound has one chiral center, it is to be understood that the name or structure encompasses one enantiomer of compound free from the corresponding optical and geometric isomer, a racemic mixture of the compound, and mixtures enriched in one enantiomer relative to its corresponding optical isomer.

[0033] When a disclosed compound is named or depicted by structure without indicating the stereochemistry and e.g, the compound has at least two chiral centers, it is to be understood that the name or structure encompasses one stereoisomer free of other stereoisomers, mixtures of stereoisomers, and mixtures of stereoisomers in which one or more stereoisomers is enriched relative to the other stereoisomer(s). For example, the name or structure may encompass one stereoisomer free of other diastereomers, mixtures of stereoisomers, and mixtures of stereoisomers in which one or more diastereomers is enriched relative to the other diastereomer(s).

[0034] With respect to the generic Formula I, Ia, II, III, IV, V, VI, and VII, unless otherwise specified, one or more hydrogens can be replaced by deuterium. Isotopic enrichments include e.g., at least 10%, 25%, 50%, 75%, 80%, 85%, 90&, 95%, 87%, 98%, 99.0%, 99.5% and 99.8%". In one embodiment, all hydrogen atoms represented in Formula I, Ia, II, III, IV, V, VI, and VII are present in natural abundance. With respect to specific compounds disclosed herein, such as those in Table 1 and in the Exemplification section, all hydrogen atoms are present in natural abundance unless otherwise specified.

[0035] The compounds described herein may be present in the form of pharmaceutically acceptable salts. For use in medicines, the salts of the compounds of the invention refer to non-toxic "pharmaceutically acceptable salts." Pharmaceutically acceptable salt forms include pharmaceutically acceptable acidic / anionic or basic / cationic salts. Suitable pharmaceutically acceptable acid addition salts of the compounds described herein include e.g., salts of inorganic acids (such as hydrochloric acid, hydrobromic, phosphoric, nitric, and sulfuric acids) and of organic acids (such as, acetic acid, benzenesulfonic, benzoic, methanesulfonic, and p-toluenesulfonic acids). Compounds of the present teachings with acidic groups such as carboxylic acids can form pharmaceutically acceptable salts with pharmaceutically acceptable base(s). Suitable pharmaceutically acceptable basic salts include e.g., ammonium salts, alkali metal salts (such as sodium and potassium salts) and alkaline earth metal salts (such as magnesium and calcium salts). Compounds with a quaternary ammonium group also contain a counteranion such as chloride, bromide, iodide, acetate, perchlorate and the like. Other examples of such salts include hydrochlorides, hydrobromides, sulfates, methanesulfonates, nitrates, benzoates and salts with amino acids such as glutamic acid. 3.

[0059] According to another embodiment, this disclosure provides a composition comprising a compound described herein or a pharmaceutically acceptable derivative thereof and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The amount of compound in compositions is such that is effective to measurably modulate potassium channels in a biological sample or in a patient.

[0060] In certain embodiments, a composition described herein is formulated for administration to a patient in need of such composition. In some embodiments, a composition described herein is formulated for oral administration to a patient.

[0061] The term "pharmaceutically acceptable carrier, adjuvant, or vehicle" refers to a non-toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions described herein include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose- based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.

[0062] Pharmaceutically acceptable compositions described herein may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

[0063] Pharmaceutically acceptable compositions described herein may also be prepared in injectable form. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

[0064] Pharmaceutically acceptable compositions described herein may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs. Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically- transdermal patches may also be used.

[0065] The amount of compounds described herein that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated and the particular mode of administration. In some embodiments, provided compositions should be formulated so that a dosage of between 0.01 - 100 mg / kg body weight / day of the inhibitor, such as e.g., <com:Math><semantics>0.1−100<annotation encoding="application / x-tex">0.1 - 100< / annotation>< / semantics>< / com:Math> mg / kg body weight / day, can be administered to a patient receiving these compositions.

[0066] It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated.

In some embodiments, a provided compound is one or more compounds selected from those exemplified in the EXEMPLIFICATION section below, or a pharmaceutically acceptable salt thereof. EXEMPLIFICATION

[0072] The representative examples that follow are intended to help illustrate the invention, and are not intended to, nor should they be construed to, limit the scope of the invention. Indeed, various modifications of the invention and many further embodiments thereof, in addition to those shown and described herein, will become apparent to those skilled in the art from the full contents of this document, including the examples that follow and the references to the scientific and patent literature cited herein.

[0073] As depicted in the Examples below, in certain exemplary embodiments, compounds are prepared according to the following general procedures. It will be appreciated that, although the synthetic methods and Schemes depict the synthesis of certain compounds of the present invention, the following methods and other methods known to one of ordinary skill in the art can be applied to all compounds and subclasses and species of each of these compounds, as described herein.

[0074] General Synthetic Scheme: Scheme 1. [Image disponible dans le document PDF, Image available in the PDF document]

[0075] In one aspect, compounds of Formula I can be prepared according to Scheme 1, where the variables R<com:Sup>1< / com:Sup>, R<com:Sup>3< / com:Sup>, R<com:Sup>5< / com:Sup>, R<com:Sup>4a< / com:Sup>, R<com:Sup>4b< / com:Sup>, X<com:Sup>1< / com:Sup>, X<com:Sup>2< / com:Sup>, and A are defined for Formula I. For example, compounds of Formula I can be prepared by reacting a compound of Formula 600 with a compound of Formula 601 in the presence of base, such as, e.g., diisopropylethylamine to form intermediate 602. Reduction with e.g., a reducing agent such as lithium aluminum hydride forms a compound of Formula 603. Reaction with a nitrogen atom on ring A affords 604 followed by halogenation with e.g., phosphorous tribromide gives 605. Treatment with amine reagent having the formula R<com:Sup>3< / com:Sup>-N in the presence of base, such as e.g., sodium t-butoxide gives 606. Scheme 1 is in no way limiting and represents only one method by which certain compounds described herein can be made. Other methods of making compounds of Formula I would be apparent to one of skill in the art. PREPARATION OF COMPOUNDS OF FORMULA I
