Title: (BIS)sulfonamide derivatives

Description:
[0001] The present invention relates to the potentiation of glutamate receptor function using certain sulphonamide derivatives. It also relates to novel sulphonamide derivatives, to processes for their preparation and to pharmaceutical compositions containing them.  
       [0002] In the mammalian central nervous system (CNS), the transmission of nerve impulses is controlled by the interaction between a neurotransmitter, that is released by a sending neuron, and a surface receptor on a receiving neuron, which causes excitation of this receiving neuron. L-Glutamate, which is the most abundant neurotransmitter in the CNS, mediates the major excitatory pathway in mammals, and is referred to as an excitatory amino acid (EAA). The receptors that respond to glutamate are called excitatory amino acid receptors (EAA receptors). See Watkins &amp; Evans,  Ann. Rev. Pharmacol. Toxicol.,  21, 165 (1981); Monaghan, Bridges, and Cotman,  Ann. Rev. Pharmacol. Toxicol.,  29, 365 (1989); Watkins, Krogsgaard-Larsen, and Honore,  Trans. Pharm. Sci.,  11, 25 (1990). The excitatory amino acids are of great physiological importance, playing a role in a variety of physiological processes, such as long-term potentiation (learning and memory), the development of synaptic plasticity, motor control, respiration, cardiovascular regulation, and sensory perception.  
       [0003] Excitatory amino acid receptors are classified into two general types. Receptors that are directly coupled to the opening of cation channels in the cell membrane of the neurons are termed “ionotropic”. This type of receptor has been subdivided into at least three subtypes, which are defined by the depolarizing actions of the selective agonists N-methyl-D-aspartate (NMDA), alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA), and kainic acid (KA). The second general type of receptor is the G-protein or second messenger-linked “metabotropic” excitatory amino acid receptor. This second type is coupled to multiple second messenger systems that lead to enhanced phosphoinositide hydrolysis, activation of phospholipase D, increases or decreases in c-AMP formation, and changes in ion channel function. Schoepp and Conn,  Trends in Pharmacol. Sci.,  14, 13 (1993). Both types of receptors appear not only to mediate normal synaptic transmission along excitatory pathways, but also participate in the modification of synaptic connections during development and throughout life. Schoepp, Bockaert, and Sladeczek,  Trends in Pharmacol. Sci.,  11, 508 (1990); McDonald and Johnson,  Brain Research Reviews,  15, 41 (1990).  
       [0004] AMPA receptors are assembled from four protein sub-units known as GluR1 to GluR4, while kainic acid receptors are assembled from the sub-units GluR5 to GluR7, and KA-1 and KA-2. Wong and Mayer,  Molecular Pharmacology  44: 505-510, 1993. It is not yet known how these sub-units are combined in the natural state. However, the structures of certain human variants of each sub-unit have been elucidated, and cell lines expressing individual sub-unit variants have been cloned and incorporated into test systems designed to identify compounds which bind to or interact with them, and hence which may modulate their function. Thus, European patent application, publication number EP-A2-0574257 discloses the human sub-unit variants GluR1B, GluR2B, GluR3A and GluR3B. European patent application, publication number EP-A1-0583917 discloses the human sub-unit variant GluR4B.  
       [0005] One distinctive property of AMPA and kainic acid receptors is their rapid deactivation and desensitization to glutamate. Yamada and Tang, The Journal of Neuroscience, September 1993, 13(9): 3904-3915 and Kathryn M. Partin,  J. Neuroscience, Nov.  1, 1996, 16(21): 6634-6647. The physiological implications of rapid desensitization, and deactivation if any, are unknown.  
       [0006] It is known that the rapid desensitization and deactivation of AMPA and/or kainic acid receptors to glutamate may be inhibited using certain compounds. This action of these compounds is often referred to in the alternative as “potentiation” of the receptors. One such compound, which selectively potentiates AMPA receptor function, is cyclothiazide. Partin et al.,  Neuron. Vol.  11, 1069-1082, 1993. Compounds which potentiate AMPA receptors, like cyclothiazide, are often referred to as ampakines.

       [0009] U.S. Pat. No. 3,267,139 discloses certain N′-trimethylacetyl-N-phenylalkylsulfamides and phenylcyclopropylsulfamides having central nervous system activity and anticonvulsant activity. The compounds are also said to produce Parkinson-like symptoms in experimental animals.  
       [0010] U.S. Pat. No. 3,860,723 discloses a method of increasing feed intake of healthy animals using certain phenylalkylsulfamides.  
       [0011] Foye et al.,  J. Pharm. Sci. ( 1971), 60(7), 1095-6 discloses certain phenylalkyl methylsulfonamides including N−1-methyl-2-phenylethyl methanesulfonamide, having hypotensive activity.  
       [0012] British Patent Specification Number 1,059,360 discloses certain phenylalkylsulfamides having activity as sedatives, narcotics and anti-convulsants, including 1-(1-methyl-2-phenylethylaminosulphonyl)piperidine.  
       [0013] U.S. Pat. No. 4,210,749 discloses N−1-methyl-2-phenyl-3-methoxy ethyl butane-sulphonamide.  
       [0014] Gualtieri et al.,  J. Pharm. Sci., ( 1973), 62(5), 849-851 discloses N−1-methyl-2-phenylethyl butanesulfonamide and its evaluation as a mosquito repellent.

       [0018] U.S. Pat. No. 3,629,332 discloses certain N-aryl- and N-heteroarylalkyl fluoroalkane sulfonamides as plant growth modifiers, including N-(alpha-methylphenylethyl) trifluoromethanesulfonamide, difluoromethanesulfonamide and fluoromethanesulfonamide. Some of the compounds are also said to have other biological activity, including insecticidal, acaricidal, nematicidal, analgesic and anti-inflammatory activity.  
       [0019] Ampakines have been shown to improve memory in a variety of animal tests. Staubli et al.,  Proc. Natl. Acad. Sci., Vol.  91, pp 777-781, 1994 , Neurobiology,  and Arai et al.,  The Journal of Pharmacology and Experimental Therapeutics,  278: 627-638, 1996.  
       [0020] It has now been found that cyclothiazide and certain sulphonamide derivatives potentiate agonist-induced excitability of human GluR4B receptor expressed in HEK 293 cells. Since cyclothiazide is known to potentiate glutamate receptor function in vivo, it is believed that this finding portends that the sulphonamide derivatives will also potentiate glutamate receptor function in vivo, and hence that the compounds will exhibit ampakine-like behavior.  
       [0021] Accordingly, the present invention provides a method of potentiating glutamate receptor function in a mammal requiring such treatment, which comprises administering an effective amount of a compound of formula  
       R 1 -L-NHSO 2 R 2   I  
       [0022] in which  
       [0023] R 1  represents an unsubstituted or substituted aromatic or heteroaromatic group;  
       [0024] R 2  represents (1-6C)alkyl, (3-6C)cycloalkyl, (1-6C)fluoroalkyl, (1-6C)chloroalkyl, (2-6C)alkenyl, (1-4C)alkoxy(1-4C)alkyl, phenyl which is unsubstituted or substituted by halogen, (1-4C)alkyl or (1-4C)alkoxy, or a group of formula R 3 R 4 N in which R 3  and R 4  each independently represents (1-4C)alkyl or, together with the nitrogen atom to which they are attached form an azetidinyl, pyrrolidinyl, piperidinyl, morpholino, piperazinyl, hexahydroazepinyl or octahydroazocinyl group; and  
       [0025] L represents a (2-4C)alkylene chain which is unsubstituted or substituted by one or two substituents selected independently from (1-6C)alkyl, aryl(1-6C)alkyl, (2-6C)alkenyl, aryl(2-6C)alkenyl and aryl, or by two substituents which, together with the carbon atom or carbon atoms to which they are attached form a (3-8C)carbocyclic ring;  
       [0026] or a pharmaceutically acceptable salt thereof.  
       [0027] According to another aspect, the present invention provides the use of a compound of formula I, or a pharmaceutically acceptable salt thereof as defined hereinabove for the manufacture of a medicament for potentiating glutamate receptor function.  
       [0028] According to yet another aspect, the present invention provides the use of a compound of formula I or a pharmaceutically acceptable salt thereof as defined hereinabove for potentiating glutamate receptor function.  
       [0029] In this specification, the term “potentiating glutamate receptor function” refers to any increased responsiveness of glutamate receptors, for example AMPA receptors, to glutamate or an agonist, and includes but is not limited to inhibition of rapid desensitisation or deactivation of AMPA receptors to glutamate.  
       [0030] A wide variety of conditions may be treated or prevented by the compounds of formula I and their pharmaceutically acceptable salts through their action as potentiators of glutamate receptor function. Such conditions include those associated with glutamate hypofunction, such as psychiatric and neurological disorders, for example cognitive disorders; neurodegenerative disorders such as Alzheimer&#39;s disease; age-related dementias; age-induced memory impairment; movement disorders such as tardive dyskinesia, Hungtington&#39;s chorea, myoclonus and Parkinson&#39;s disease; reversal of drug-induced states (such as cocaine, amphetamines, alcohol-induced states); depression; attention deficit disorder; attention deficit hyperactivity disorder; psychosis; cognitive deficits associated with psychosis; and drug-induced psychosis. The compounds of formula I may also be useful for improving memory (both short term and long term) and learning ability. The present invention provides the use of compounds of formula I for the treatment of each of these conditions.  
       [0031] It will be appreciated that the compounds of formula I may contain one or more asymmetric carbon atoms, and may therefore exist in and be used in the form of individual enantiomers. The present invention includes the individual enantiomers of the compounds of formula I.

       [0110] (c) R 1  represents 4-nitrophenyl and R 2  represents trifluoromethyl.  
       [0111] The compounds of formula I may be prepared by reacting a compound of formula  
       R 1 -L-NH 2   II  
       [0112] with a compound of formula  
       R 2 SO 2 X  III  
       [0113] in which X represents a leaving atom or group, followed where necessary and/or desired by forming a pharmaceutically acceptable salt.  
       [0114] The leaving atom or group represented by X may be, for example, a halogen atom such as a chlorine or bromine atom.  
       [0115] The reaction is conveniently performed in the presence of a base, for example an alkali metal hydroxide such as sodium hydroxide, an alkali metal carbonate such as potassium carbonate, a tertiary amine such as triethylamine or 1,8-diazabicyclo[5.4.0]undec-7-ene.  
       [0116] Suitable solvents include halogenated hydrocarbons such as dichloromethane.  
       [0117] The reaction is conveniently performed at a temperature in the range of from −20 to 100° C., preferably from −5 to 50° C.  
       [0118] The compounds of formula I in which R 1  represents a 4-bromophenyl group may conveniently be converted into other compounds of formula I in which R represents another 4-substituted phenyl group by reaction with an appropriate boronic acid derivative, for example, a benzeneboronic acid derivative. The reaction is conveniently performed in the presence of a tetrakis (triarylphosphine)palladium(0) catalyst, such as tetrakis (triphenylphosphine)palladium(0) and a base such as potassium carbonate. Convenient solvents for the reaction include aromatic hydrocarbons, such as toluene. The temperature at which the reaction is conducted is conveniently in the range of from 0 to 150° C., preferably 75 to 120° C. Bis aromatic intermediates useful in the preparation of compounds of formula I may be prepared by reacting a bromoaromatic or bromoheteroaromatic compound with an aromatic or heteroaromatic boronic acid in an analogous manner.  
       [0119] The boronic acid derivative used as a starting material may be prepared by reacting a trialkyl borate, such as triisopropyl borate with an appropriate organolithium compound at reduced temperature. For example, 2-fluorobenzeneboronic acid may be prepared by reacting 2-fluorobromobenzene with butyllithium in tetrahydrofuran at about −78° C. to afford 2-fluorophenyl lithium, and then reacting this organolithium compound with triisopropyl borate.  
       [0120] Alternatively, the compounds of formula I in which R 1  represents a 4-bromophenyl group may be converted to a 4-(trimethylstannyl)phenyl or 4-(tri-n-butylstannyl)phenyl group by treatment of the corresponding bromide with a palladium(0) catalyst, such as tetrakis(triphenylphosphine)-palladium(0) and hexaalkyldistannane, where the alkyl group is methyl or n-butyl, in an aprotic solvent such as toluene in the presence of a tertiary amine base such as triethylamine, at temperatures ranging from 80 to 140° C., preferably from 90 to 110° C.  
       [0121] The compounds of formula I in which R 1  represents a 4-(tri-n-butylstannyl)phenyl group may then be reacted with an aryl- or heteroarylbromide, such as 2-bromothiophene-5-carboxaldehyde, in the presence of a palladium(0) catalyst, such as tetrakis(triphenylphosphine)palladium(0), or a palladium(II) catalyst, such as bis(triphenylphosphine)-palladium(II) dichloride, in an aprotic solvent, such as dioxane, at temperatures ranging from 80 to 140° C., preferably from 90 to 110° C., to afford the corresponding 4-(aryl)phenyl or 4-(heteroaryl)phenyl substituted compound.  
       [0122] The compounds of formula I in which R 1  represents a 4-bromophenyl group may be converted into other compounds of formula I in which R 1  represents a 4-substituted alkyl- or cycloalkylphenyl group, such as 4-cyclopentylphenyl by treatment of the corresponding bromide with an appropriate alkyl- or cycloalkyl Grignard reagent, such as cyclopentylmagnesium bromide, in the presence of a palladium(II) catalyst, such as [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II) (PdCl 2 (dppf)), in an aprotic solvent, such as diethyl ether at temperatures ranging from −78° C. to 25° C.  
       [0123] The compounds of formula I in which R 1  represents a 4-bromophenyl group may be converted into a 4-substituted carboxyaldehydephenyl(formylphenyl) group by reaction of the corresponding bromide with the carbon monoxide gas which is bubbled into the reaction under atmospheric pressure in the presence of a palladium(II) catalyst, such as bis(triphenylphosphine)palladium(II) dichloride and sodium formate in an aprotic solvent, such as dimethylformamide at temperatures ranging from 70 to 110° C., preferably at 90° C.  
       [0124] The compounds of formula I in which R 1  represents a 4-hydroxyphenyl group may be converted into other compounds of formula I in which R 1  represents an alkoxy group by treatment of the corresponding hydroxyphenyl group with an appropriate alkylhalide such as benzylbromide in the presence of sodium hydride in an aprotic solvent such as dimethylformamide at temperatures ranging from 25 to 100° C., preferably from 50 to 90° C.  
       [0125] The compounds of formula II are known or may be prepared by conventional methods, for example by reducing a corresponding amide or nitrile using borane.  
       [0126] Some of the nitrites or amides used as starting materials may conveniently be prepared by treatment of an acetonitrile of formula R 1 CH 2 CN, for example a substituted phenylacetonitrile such as 4-methoxyphenylacetonitrile or an acetate of formula R 1 CH 2 COOR (where R is, for example alkyl), for example a phenylacetate such as methyl 4-tert-butylphenylacetate, with a strong lithium amide base, such as sodium or lithium bis(trimethylsilyl) amide, and an alkylhalide, such as methyl iodide, in an aprotic solvent, such as tetrahydrofuran, at a temperature ranging from −78 to 25° C. The esters are converted to amides by hydrolysis (water, alcohol and sodium or potassium hydroxide) to the acid, conversion of the acid to the acid chloride (SOCl 2  or (COCl) 2  plus DMF (1 drop)) then conversion to the amide with aqueous ammonia and a co-solvent such as tetrahydrofuran or dioxane.  
       [0127] Certain nitriles used to prepare compounds of formula II may also conveniently be prepared by reacting a corresponding ketone derivative, for example a compound of formula R 1 COR 8 , such as (2-acetyl-5-thien-3-yl)thiophene, with tosylmethylisocyanide and potassium t-butoxide in dimethyl ether.  
       [0128] The ability of compounds of formula I to potentiate glutamate receptor function may be demonstrated using the following test procedures.  
       [0129] 96 well plates containing confluent monolayers of HEK cells stably expressing human GluR 4 B (obtained as described in European Patent Application Publication Number EP-A1-583917) were prepared. The tissue culture medium in the wells was then discarded, and the wells were each washed once with 200 μl of 5NaCa buffer (glucose, 10 mM, sodium chloride, 138 mM, magnesium chloride, 1 mM, potassium chloride, 5 mM, calcium chloride, 5 mM, N-[2-hydroxyethyl]-piperazine-N-[2-ethanesulfonic acid], 10 mM, to pH 7.1 to 7.3). The plates were then incubated for 60 minutes in the dark with 20 μM Fluo3-AM dye (obtained from Molecular Probes Inc, Eugene, Oreg.) in 5 NaCa buffer in each well. After the incubation, each well was washed once with 100 μl 5NaCa buffer, 200 μl of 5NaCa buffer was added and the plates were incubated for 30 minutes.  
       [0130] Solutions for use in the test were also prepared as follows. 30 μM, 10 μM, 3 μM and 1 μM dilutions of test compound were prepared using 5NaCa buffer from a 10 mM solution of test compound in DMSO. 100 μM cyclothiazide solution was prepared by adding 3 μl of 100 mM cyclothiazide to 3 ml of 5 NaCa buffer. Control buffer solution was prepared by adding 1.5 μl DMSO to 498.5 μl of 5NaCa buffer.  
       [0131] Each test was then performed as follows. The 200 μl of 5 NaCa buffer in each well was discarded, and replaced with 45 μl of 5 NaCa buffer. A first reading was then taken using a FLUOROSKAN II fluorimeter (Obtained from Labsystems, Needham Heights, Mass., USA, a Division of Life Sciences International Plc). The buffer was then discarded from the wells, 45 μl of 5 NaCa buffer was added to the outer wells and 45 μl of test compound solution was added to the inner wells. A second reading was then taken using the fluorimeter. The plate was then left in the fluorimeter for 5 minutes, and a third reading was taken. 15 μl of 400 μM glutamate solution was then added to each well (final glutamate concentration 100 μM), and a fourth reading was taken immediately. Approximately three minutes later, a fifth reading was taken.  
       [0132] The activities of test compounds, control and cyclothiazide solutions was determined by subtracting the third from the fourth reading (fluorescence due to glutamate). The activities of test compounds were expressed relative to that of 100 μM cyclothiazide.  
       [0133] In another test, HEK293 cells stably expressing human GluR 4  (obtained as described in European Patent Application Publication No. EP-A1-0583917) were used in the electro-physiological characterization of AMPA receptor potentiators. The extracellular recording solution contained (in mM): 140 NaCl, 5 KCl, 10 HEPES, 1 MgCl 2 , 2 CaCl 2 , 10 glucose, pH=7.4 with NaOH, 295 mOsm kg −1 . The intracellular recording solution contained (in mM): 140 CsCl, 1 MgCl 2 , 10 HEPES, (N-[2-hydroxyethyl]piperazine-N 1 -[2-ethanesulfonic acid]) 10 EGTA (ethylene-bis(oxyethylene-nitrilo)tetraacetic acid), pH=7.2 with CsOH, 295 mOsm kg −1 . With these solutions, recording pipettes had a resistance of 2-3 MΩ. Using the whole cell voltage clamp technique, cells were voltage-clamped at −60 mV and control responses to 100M glutamate were evoked. Once stable baseline responses to this agonist challenge were obtained, the potentiator was introduced in the extracellular solution bathing the cells at the lowest concentration, and the response to 100 μM glutamate in the presence of this concentration of potentiator was determined.  
       [0134] The concentration of the potentiator, both in the bathing solution and co-applied with the agonist, was increased in half log units until the maximum potentiation was seen. Data collected in this manner was fit to the Hill equation, yielding an EC 50  value, indicative of the potency of the potentiator. The potentiator was then washed out of both the control solution and the agonist-containing solution in order to investigate its reversal. Once the control responses to the agonist challenge were re-established, the potentiation of these responses by 100 μM cyclothiazide was determined by its inclusion in both the bathing solution and the agonist-containing solution. In this manner, the efficacy of the potentiator relative to that of cyclothiazide could be determined.  
       [0135] The compounds exemplified herein were found to give an EC 50  in this test of at least 30 μM. For instance, the compound of Example 28 gave an EC 50  of 230±59 nM.  
       [0136] According to another aspect, the present invention provides a pharmaceutical composition, which comprises a compound of formula Ia or a pharmaceutically acceptable salt thereof as defined hereinabove and a pharmaceutically acceptable diluent or carrier.  
       [0137] The pharmaceutical compositions are prepared by known procedures using well-known and readily available ingredients. In making the compositions of the present invention, the active ingredient will usually be mixed with a carrier, or diluted by a carrier, or enclosed within a carrier, and may be in the form of a capsule, sachet, paper, or other container. When the carrier serves as a diluent, it may be a solid, semi-solid, or liquid material which acts as a vehicle, excipient, or medium for the active ingredient. The compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols, ointments containing, for example, up to 10% by weight of active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.  
       [0138] Some examples of suitable carriers, excipients, and diluents include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum, acacia, calcium phosphate, alginates, tragcanth, gelatin, calcium silicate, micro-crystalline cellulose, polyvinylpyrrolidone, cellulose, water syrup, methyl cellulose, methyl and propyl hydroxybenzoates, talc, magnesium stearate, and mineral oil. The formulations can additionally include lubricating agents, wetting agents, emulsifying and suspending agents, preserving agents, sweetening agents, or flavoring agents. Compositions of the invention may be formulated so as to provide quick, sustained, or delayed release of the active ingredient after administration to the patient by employing procedures well known in the art.  
       [0139] The compositions are preferably formulated in a unit dosage form, each dosage containing from about 1 mg to about 500 mg, more preferably about 5 mg to about 300 mg (for example 25 mg) of the active ingredient. The term “unit dosage form” refers to a physically discrete unit suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical carrier, diluent, or excipient. The following formulation examples are illustrative only and are not intended to limit the scope of the invention in any way.

       [0143] The active ingredient, starch, and cellulose are passed through a No. 45 mesh U.S. sieve and mixed thoroughly. The solution of polyvinylpyrrolidone is mixed with the resultant powders which are then passed through a No. 14 mesh U.S. sieve. The granules so produced are dried at 50° C. and passed through a No. 18 mesh U.S. sieve. The sodium carboxymethyl starch, magnesium stearate, and talc, previously passed through a No. 60 mesh U.S. sieve, are then added to the granules which, after mixing, are compressed on a tablet machine to yield tablets each weighing 150 mg.  
       [0144] The particular dose of compound administered according to this invention will of course be determined by the particular circumstances surrounding the case, including the compound administered, the route of administration, the particular condition being treated, and similar considerations. The compounds can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, or intranasal routes. Alternatively, the compound may be administered by continuous infusion. A typical daily dose will contain from about 0.01 mg/kg to about 100 mg/kg of the active compound of this invention. Preferably, daily doses will be about 0.05 mg/kg to about 50 mg/kg, more preferably from about 0.1 mg/kg to about 25 mg/kg.
