Abstract: The present invention provides compounds of formula (I): useful for potentiating glutamate receptor function in a mammal and therefore, useful for treating a wide variety of conditions, such as psychiatric and neurological disorders.

Description: CYCLOALKYLFLUOROSULFONAMIDE DERIVATIVES 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 & 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. 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 /V-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). 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 GluR1 B, GluR2B, GluR3A and GluR3B. European patent application, publication number EP-A1- 0583917 discloses the human sub-unit variant GluR4B. One distinctive property of AMPA and kainic acid receptors is their rapid deactivation and desensitization to glutamate. Yamada and Tang, The Journal of Ηeuroscience, September 1993, 13(9): 3904-3915 and Kathryn M. Partin, . Neuroscience, November 1 , 1996, 16(21 ): 6634-6647. 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. International Patent Application Publication WO 98/33496 published August 6, 1998 discloses certain sulfonamide derivatives which are useful, for example, for treating psychiatric and neurological disorders, for example cognitive disorders; neuro-degenerative disorders such as Alzheimer's disease; age-related dementias; age-induced memory impairment; movement disorders such as tardive dyskinesia, Huntington's chorea, myoclonus, and Parkinson'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 present invention provides the use of compounds of formula I for the treatment of each of these conditions. The present invention includes the pharmaceutically acceptable salts of the compounds defined by formula I. A compound of this invention can possess a sufficiently acidic group, a sufficiently basic group, or both functional groups, and accordingly react with any of a number of organic and inorganic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. The term "pharmaceutically acceptable salt" as used herein, refers to salts of the compounds of the above formula which are substantially non-toxic to living organisms. Typical pharmaceutically acceptable salts include those salts prepared by reaction of the compounds of the present invention with a pharmaceutically acceptable mineral or organic acid or an organic or inorganic base. Such salts are known as acid addition and base addition salts. Such salts include the pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science, 66, 2-19 (1977) which are known to the skilled artisan. Acids commonly employed to form acid addition salts are inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, and the like, and organic acids such as p-toluenesulfonic, methanesulfonic acid, benzenesulfonic acid, oxalic acid, p-bromophenylsulfonic acid, carbonic acid, succinic acid, citric acid, benzoic acid, acetic acid, and the like. Examples of such pharmaceutically acceptable salts are the sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, hydrobromide, iodide, acetate, propionate, decanoate, caprate, caprylate, acrylate, ascorbate, formate, hydrochloride, dihydrochloride, isobutyrate, caproate, heptanoate, propiolate, propionate, phenylpropionate, salicylate, oxalate, malonate, succinate, suberate, sebacate, fumarate, malate, maleate, hydroxymaleate, mandelate, nicotinate, isonicotinate, cinnamate, hippurate, nitrate, phthalate, teraphthalate, butyne-1 ,4- dioate, butyne-1 ,4-dicarboxylate, hexyne-1 ,4-dicarboxylate, hexyne-1 ,6-dioate, benzoate, chlorobenzoate, methylbenzoate, hydroxybenzoate, methoxybenzoate, dinitrobenzoate, o-acetoxybenzoate, naphthalene-2-benzoate, phthalate, p- toluenesulfonate, p-bromobenzenesulfonate, p-chlorobenzenesulfonate, xylenesulfonate, phenylacetate, trifluoroacetate,; phenylpropionate, phenylbutyrate, citrate, lactate, -hydroxybutyrate, glycolate, tartrate, benzenesulfonate, methanesulfonate, ethanesulfonate, propanesulfonate, hydroxyethanesulfonate, 1-naphthalenesulfonate, 2-napththalenesulfonate, 1 ,5- naphthalenedisulfonate, mandelate, tartarate, and the like. Preferred pharmaceutically acceptable acid addition salts are those formed with mineral acids such as hydrochloric acid and hydrobromic acid, and those formed with organic acids such as maleic acid, oxalic acid and methanesulfonic acid. Base addition salts include those derived from inorganic bases, such as ammonium or alkali or alkaline earth metal hydroxides, carbonates, bicarbonates, and the like. Such bases useful in preparing the salts of this invention thus include sodium hydroxide, potassium hydroxide, ammonium hydroxide, potassium carbonate, sodium carbonate, sodium bicarbonate, potassium bicarbonate, calcium hydroxide, calcium carbonate, and the like. The potassium and sodium salt forms are particularly preferred. It should be recognized that the particular counterion forming a part of any salt of this invention is usually not of a critical nature, so long as the salt as a whole is pharmacologically acceptable and as long as the counterion does not contribute undesired qualities to the salt as a whole. It is further understood that the above salts may form hydrates or exist in a substantially anhydrous form. As used herein, the term "stereoisomer" refers to a compound made up of the same atoms bonded by the same bonds but having different three- dimensional structures which are not interchangeable. The three-dimensional structures are called configurations. As used herein, the term "enantiomer" refers to two stereoisomers whose molecules are nonsuperimposable mirror images of one another. The term "chiral center" refers to a carbon atom to which four different groups are attached. As used herein, the term "diastereomers" refers to stereoisomers which are not enantiomers. In addition, two diastereomers which have a different configuration at only one chiral center are referred to herein as "epimers". The terms "racemate", "racemic mixture" or "racemic modification" refer to a mixture of equal parts of enantiomers. The term "enantiomeric enrichment" as used herein refers to the increase in the amount of one enantiomer as compared to the other. A convenient method of expressing the enantiomeric enrichment achieved is the concept of enantiomeric excess, or "ee", which is found using the following equation: ee = E^ - E 2 X 100 E π + E wherein E 1 is the amount of the first enantiomer and E 2 is the amount of the second enantiomer. Thus, if the initial ratio of the two enantiomers is 50:50, such as is present in a racemic mixture, and an enantiomeric enrichment sufficient to produce a final ratio of 70:30 is achieved, the ee with respect to the first enantiomer is 40%. However, if the final ratio is 90:10, the ee with respect to the first enantiomer is 80%. An ee of greater than 90% is preferred, an ee of greater than 95% is most preferred and an ee of greater than 99% is most especially preferred. Enantiomeric enrichment is readily determined by one of ordinary skill in the art using standard techniques and procedures, such as gas or high performance liquid chromatography with a chiral column. Choice of the appropriate chiral column, eluent and conditions necessary to effect separation of the enantiomeric pair is well within the knowledge of one of ordinary skill in the art. In addition, the specific stereoisomers and enantiomers of compounds of formula I can be prepared by one of ordinary skill in the art utilizing well known techniques and processes, such as those disclosed by J. Jacques, et al., "Enantiomers, Racemates, and Resolutions", John Wiley and Sons, Inc., 1981 , and E.L. Eliel and S.H. Wilen," Stereochemistry of Organic Compounds", (Wiley- Interscience 1994), and European Patent Application No. EP-A-838448, published April 29, 1998. Examples of resolutions include recrystallization techniques or chiral chromatography. Some of the compounds of the present invention have one or more chiral centers and may exist in a variety of stereoisomeric configurations. As a consequence of these chiral centers, the compounds of the present invention occur as racemates, mixtures of enantiomers and as individual enantiomers, as well as diastereomers and mixtures of diastereomers. All such racemates, enantiomers, and diastereomers are within the scope of the present invention. The terms "R" and "S" are used herein as commonly used in organic chemistry to denote specific configuration of a chiral center. The term "R" (rectus) refers to that configuration of a chiral center with a clockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The term "S" (sinister) refers to that configuration of a chiral center with a counterclockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The priority of groups is based upon their atomic number (in order of decreasing atomic number). A partial list of priorities and a discussion of stereochemistry is contained in "Nomenclature of Organic Compounds: Principles and Practice", (J.H. Fletcher, et al., eds., 1974) at pages 103-120. As used herein the term "bis(pinacolato)diboron" refers to the following structure: As used herein, the term "aromatic group" means the same as aryl, and includes phenyl and a polycyclic aromatic carbocyclic ring such as 1- or 2- naphthyl, 1 ,2-dihydronaphthyl, 1 ,2,3,4-tetrahydronaphthyl, and the like. Phenyl is the preferred aromatic group. The term "heteroaromatic group" includes an aromatic 5-6 membered ring containing from one to four heteroatoms selected from oxygen, sulfur and nitrogen, and a bicyclic group consisting of a 5-6 membered ring containing from one to four heteroatoms selected from oxygen, sulfur and nitrogen fused with a benzene ring or another 5-6 membered ring containing one to four atoms selected from oxygen, sulfur and nitrogen. Examples of heteroaromatic groups are thienyl, furyl, oxazolyl, isoxazolyl, oxadiazoyl, pyrazolyl, thiazolyl, thiadiazolyl, isothiazolyl, imidazolyl, triazolyl, tetrazolyl, pyridyl, pyridazinyl, pyrimidyl, benzofuryl, benzothienyl, benzimidazolyl, benzoxazolyl, benzothiazolyl, indolyl, and quinolyl. The term (5-8C)cycloalkyl includes cyclαpentyl; cyclohexyl, cycloheptyi 1 and cyclooctyl. The term "substituted" as used in the term "substituted aromatic, heteroaromatic group, or substituted (5-8C)cycloalkyl group " herein signifies that one or more (for example one or two) substituents may be present, said substituents being selected from atoms and groups which, when present in the compound of formula I, do not prevent the compound of formula I from functioning as a potentiator of glutamate receptor function. It is understood that when R 1 represents an unsubstituted or substituted (5-8C)cycloalkyl group, mixtures of cis and trans isomers may result which can be separated into the individual cis and trans isomers by one of ordinary skill in the art, using standard techniques and procedures such as reverse phase or normal phase high performance liquid chromatography or flash chromatography, with a suitable stationary phase and a suitable eluent. Examples of suitable stationary phases are silica gel, alumina, and the like: Examples of suitable eluents are ethyl acetate/hexane, ethyl acetate/toluene, methanol/dichloromethane, and the like. Such individual cis and trans isomers are included within the scope of the present invention. Examples of substituents which may be present on a substituted aromatic group, a substituted heteroaromatic group, or a substituted (5-8)C cycloalkyl group include halogen; nitro; cyano; (1-1 OC) alkyl; (2-10C)alkenyl; (2- 10C)alkynyl; (3-8C)cycloalkyl; hydroxy(3-8C)cycloalkyl; oxo(3-8C)cycloalkyl; halo(1-10C)alkyl; -0-(CH 2 ) t CN, -0-(CH 2 ) t NH 2 , -O-(CH 2 ) t NHCORl0a j -O-(CH 2 )tNHSO 2 R 10a in which t is an integer of from 1 to 4; (CH2)yX 1 R 9 in which y is 0 or an integer of from 1 to 4, χ1 represents O, S, NR^O, CO, COO, OCO, CONR11 , NR12CO, NR12C0C00, OCONR 13 , R 9 represents hydrogen, (1-1 OC) alkyl, (3-10C)alkenyl, (3-10C)alkynyl, pyrrolidinyl, tetrahydrofuryl, morpholino or (3-8C)cycloalkyl and R 10 > R 0a - R1 > R 12 and R 3 each independently represents hydrogen or (1-10C)alkyl, or R 9 and R^O.

Table 1 The compounds of formula I can be prepared by one of ordinary skill in the art, for example, following the procedures set forth below in Schemes l-VII. The reagents and starting materials are readily available to one of ordinary skill in the art. All substituents, unless otherwise specified are as previously defined. Scheme I R- — Hal formula la (8) In Scheme I, step A, the compound of structure (1) is combined with the ketone of structure (2) under standard Grignard conditions well known in the art to provide the alcohol (3), for example see Jerry March, "Advanced Organic Chemistry: Reactions, Mechanisms, and Structure," Fourth Edition, John Wiley & Sons, (1992) pages 920-929. More specifically, for example, magnesium turnings are added to a suitable organic solvent, such as anhydrous THF under an atmosphere of nitrogen. A small amount of compound (1) is added along with an iodine crystal and a catalytic amount of dibromoethane. The reaction is heated with vigorous stirring to initiate the Grignard formation. A total of about 1.1 equivalents of compound (1 ) is added dropwise to the reaction. The reaction is then allowed to cool to room temperature and about 1.06 equivalents of ketone (2) is added dropwise to the reaction. The reaction mixture is then heated at reflux for about 2 hours and allowed to cool to room temperature overnight. The alcohol (3) is then isolated using standard techniques. For example, saturated ammonium chloride is added to precipitate the salts. The organic layer is decanted off and the remaining salts are rinsed with ether which is combined with the first organic layer. The combined organics are concentrated under vacuum and the residue is taken up in a suitable organic solvent, such as ethyl acetate, dried over potassium carbonate, filtered, and concentrated under vacuum to provide crude alcohol (3). The crude material can then be purified using standard techniques, such as chromatography on silica gel with a suitable eluent, such as hexane/ethyl acetate to provide purified alcohol (3). In Scheme I, step B the alcohol (3) is dehydrated under standard conditions to provide the compound (4). For example, the alcohol (3) is dissolved in a suitable organic solvent, such as toluene and treated with p- toluenesulfonic acid. The reaction mixture is heated at reflux for about 4 hours and water is removed using a Dean-Stark trap. The reaction mixture is then allowed to cool to room temperature and concentrated under vacuum. The crude residue is taken up in a suitable organic solvent, such as methylene chloride, washed with water, dried over potassium carbonate, filtered, and concentrated under vacuum. The crude product (4) can be purified by chromatography on silica gel with a suitable eluent, such as hexane/methylene chloride. In Scheme I, step C the compound (4) is epoxidized under conditions well known in the art to provide the epoxide (5). For example, about 3 equivalents m- chloroperbenzoic acid is added portionwise to about 5 equivalents of sodium fluoride in a suitable organic solvent, such as methylene chloride. The reaction mixture is allowed to stir for about 30 minutes at room temperature and compound (4) is added to the mixture in one portion. The reaction mixture is then allowed to stir for about 2 to 4 hours at room temperature, and then is filtered. The filtrate is washed with 1 N sodium hydroxide, water, dried over potassium carbonate, filtered, and concentrated under vacuum to provide the crude epoxide (5). This crude material can be purified using silica gel chromatography with a suitable eluent, such as hexane/methylene chloride to provide the purified epoxide (5). ln Scheme I, step D, the epoxide (5) is opened under standard conditions to provide the azide (6). For example, 1.08 equivalents of epoxide (5) dissolved in a suitable organic solvent, such as DMF, is added dropwise at room temperature to a mixture of sodium azide in water. The reaction is heated at 90°C with stirring for about 8 to 12 hours. The mixture is then poured into water and extracted with a suitable organic solvent, such as ether. The organic layer is washed with water, dried over potassium carbonate, filtered, and concentrated under vacuum to provide the azide (6). In Scheme I, step E, the azide (6) is converted to the amine (7) under conditions well known in the art. For example, azide (6) is dissolved in a suitable organic solvent, such as toluene and added dropwise to a suitable reducing agent, such as Red-AI ® (available from Aldrich Chemical Company, Milwaukee, Wisconsin) under a nitrogen atmosphere at room temperature. The reaction mixture is allowed to stir for 1 to 4 hours and then is poured into water. The aqueous is extracted with a suitable organic solvent, such as ethyl acetate. The organic extracts are combined, rinsed with water, dried over anhydrous potassium carbonate, filtered, and concentrated under vacuum to provide the crude amine (7). This crude material can be purified by chromatography on silica gel with a suitable eluent, such as methylene chloride/methanol to provide purified amine (7). In Scheme I, step F, the amine (7) is converted to the sulfonamide of compound (8) under conditions well known in the art. For example, amine (7) is dissolved in a suitable organic solvent. Examples of suitable organic solvents include methylene chloride, tetrahydrofuran, and the like. The solution is treated with a slight excess of a suitable base, and then cooled to about -78°C to about 0°C. Examples of suitable bases include triethylamine, pyridine, 1 ,8- diazabicyclo[5.4.0]undec-7-ene (DBU).and the like. To the stirring solution is added one equivalent of LgS0 2 R 2 . The term "Lg" as used herein refers to a suitable leaving group. Examples of suitable leaving groups include, CI, Br, and the like. CI is the preferred leaving group. The reaction mixture is stirred at about 0°C to about 50°C for about 0.5 hours to about 16 hours. The sulfonamide (8) is then isolated and purified by techniques well known in the art, such as extraction techniques and chromatography. For example, the mixture is washed with 10% sodium bisulfate, the layers separated and the aqueous extracted with several times with a suitable organic solvent, such as methylene chloride. The organic extracts are combined, dried over anhydrous sodium sulfate, filtered and concentrated under vacuum. The residue is then purified by flash chromatography on silica gel with a suitable eluent such as ethyl acetate/hexane to provide the sulfonamide (8). In Scheme I, step G, the sulfonamide (8) is converted to compound of formula la under standard conditions well known in the art. For example, compound (8) is dissolved in a suitable organic solvent, such as methylene chloride and the solution is cooled to about -78°C under an inert atmosphere, such as nitrogen. To this solution is added slowly, about one equivalent of diethylaminosulfur trifluoride (DAST) dissolved in a suitable organic solvent, such as methylene chloride with stirring. The reaction is then allowed to warm to room temperature and the compound of formula la is then isolated and purified using techniques and procedures well known in the art, such as extraction techniques r , and chromatography. For example, the reaction is diluted with water and methylene chloride. The layers are separated and the organic layer is washed with water, dried over anhydrous sodium sulfate, filtered and concentrated under vacuum to provide the crude compound of formula la. This crude material can then be purified by standard techniques, such as recrystallization from a suitable eluent, or flash chromatography or radial chromatography on silica gel, with a suitable eluent, such as hexane/ethyl acetate or methylene chloride to provide purified compound of formula la. Scheme IA Step B (12) (11) R— Hal Step D (1 ) In Scheme IA, step A, the compound of structure (9) is amidated to provide the sulfonamide of structure (10) in a manner analogous to the procedure set forth in Scheme I, step F. In Scheme IA, step B, the sulfonamide (10) is deprotected under standard conditions to provide the alcohol of structure (11 ). For example, the sulfonamide (10) is dissolved in a suitable organic solvent, such as ethanol, treated with a suitable hydrogenation catalyst, such as palladium on carbon and placed under a hydrogen atmosphere at about 60 psi for about 8 to 16 hours. The reaction mixture is then filtered and the filtrate is concentrated under vacuum to provide the alcohol (11 ). ln Scheme IA, step C, the alcohol (11) is oxidized under conditions well known in the art to provide the ketone of structure (12). For example, the alcohol (11 ) dissolved in a suitable organic solvent, such as methylene chloride and treated with about 1.1 to 1.5 equivalents of a suitable oxidizing reagent, such as pyridinium chlorochromate (PCC). The reaction mixture is allowed to stir for about 2 to 8 hours and is then filtered through Celite ® . The filtrate is washed with water, dried over potassium carbonate, filtered, and concentrated under vacuum to provide the crude ketone (12). The ketone (12) can be purified by chromatography on silica gel with a suitable eluent, such as methylene chloride/ethyl acetate to provide the purified ketone (12). In Scheme IA, step D, the ketone (12) is combined with the compound of structure (1) under standard Grignard conditions in a manner analogous to the procedure set forth in Scheme I, step A above to provide the alcohol of structure (8'). It is understood by one of ordinary skill in the art that a mixture of cis/trans isomers will be obtained in this reaction: These isomers can be separated using standard separation techniques well known in the art such as chromatography on silica gel with a suitable eluent, such as ethyl acetate/hexane. Alternatively, the cis/trans mixture can be carried on to step E below and the mixture can then be separated. In Scheme IA, step E, the alcohol (8') is fluorinated in a manner analogous to the procedure set forth in Scheme I, step G above to provide the compounds of formula la". Scheme R— Hal In Scheme II, step A the compound (1) is combined with compound (2a) under standard Grignard conditions well known in the art to provide the alcohol (3) as described above in Scheme I, step A. In Scheme II, step B, the compound (2a) is reduced under conditions well known in the art to provide the amines (7) and (7a). For example, compound (2a) is dissolved in a suitable organic solvent, such as ethanol, a catalytic amount of a suitable catalyst, such as palladium on carbon is added, and the reaction mixture is placed under hydrogen at about 60 psi for about 8 to 12 hours. The reaction mixture is then filtered through Celite ® and the filtrate is concentrated under vacuum to provide the crude mixture of (7) and (7a). The compounds (7) and (7a) can then be separated by chromatography on silica gel with a suitable eluent, such as methanol/methylene chloride. In Scheme II, step C, amine (7) is sulfonylated in a manner analogous to the procedure set forth in Scheme I, step F, to provide the sulfonamide (8). In Scheme II, step C, amine (7a) is sulfonylated in a manner analogous to the procedure set forth in Scheme I, step F, to provide the sulfonamide (8a).

The ability of compounds of formula I to potentiate glutamate receptor- mediated response may be determined using fluorescent calcium indicator dyes (Molecular Probes, Eugene, Oregon, Fluo-3) and by measuring glutamate- evoked efflux of calcium into GluR4 transfected HEK293 cells, as described in more detail below. In one test, 96 well plates containing confluent monolayers of HEK 293 cells stably expressing human GluR4B (obtained as described in European Patent Application Publication Number EP-A1-583917) are prepared. The tissue culture medium in the wells is then discarded, and the wells are each washed once with 200 μl of buffer (glucose, 10mM, sodium chloride, 138mM, magnesium chloride, 1 mM, potassium chloride, 5mM, calcium chloride, 5mM, N-[2- hydroxyethyl]-piperazine-N-[2-ethanesulfonic acid], 10mM, to pH 7.1 to 7.3). The plates are then incubated for 60 minutes in the dark with 20 μM Fluo3-AM dye (obtained from Molecular Probes Inc., Eugene, Oregon) in buffer in each well. After the incubation, each well is washed once with 100 μl buffer, 200 μl of buffer is added and the plates are incubated for 30 minutes. Solutions for use in the test are also prepared as follows. 30 μM, 10 μM, 3 μM and 1 μM dilutions of test compound are prepared using buffer from a 10 mM solution of test compound in DMSO. 100 μM cyclothiazide solution is prepared by adding 3 μl of 100 mM cyclothiazide to 3 mL of buffer. Control buffer solution is prepared by adding 1.5 μl DMSO to 498.5 μl of buffer. Each test is then performed as follows. 200 μl of control buffer in each well is discarded and replaced with 45 μl of control buffer solution. A baseline fluorescent measurement is taken using a FLUOROSKAN II fluorimeter (Obtained from Labsystems, Needham Heights, MA, USA, a Division of Life Sciences International Pic). The buffer- is then removed and replaced with 45 μl of buffer and 45 μl of test compound in buffer in appropriate wells. A second fluorescent reading is taken after 5 minutes incubation. 15 μl of 400 μM glutamate solution is then added to each well (final glutamate concentration 100 μM), and a third reading is taken. The activities of test compounds and cyclothiazide solutions are determined by subtracting the second from the third reading (fluorescence due to addition of glutamate in the presence or absence of test compound or cyclothiazide) and are expressed relative to enhance fluorescence produced by 100 μM cyclothiazide. In another test, HEK293 cells stably expressing human GluR4 (obtained as described in European Patent Application Publication No. EP-A1 -0583917) are used in the electrophysiological characterization of AMPA receptor potentiators. The extracellular recording solution contains (in mM): 140 NaCl, 5 KCI, 10 HEPES, 1 MgCI 2 , 2 CaCI 2 , 10 glucose, pH = 7.4 with NaOH, 295 mOsm kg-1. The intracellular recording solution contains (in mM): 140 CsCI, 1 MgCI 2 , 10 HEPES, (N-[2-hydroxyethyl]piperazine-N1-[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 have a resistance of 2-3 MΩ. Using the whole-cell voltage clamp technique (Hamill et al.(1981 )Pflϋgers Arch., 391 : 85-100), cells are voltage-clamped at -60mV and control current responses to 1 mM glutamate are evoked. Responses to 1 mM glutamate are then determined in the presence of test compound. Compounds are deemed active in this test if, at a test concentration of 10 μM or less, they produce a greater than 10% increase in the value of the current evoked by 1 mM glutamate. In order to determine the potency of test compounds, the concentration of the test compound, both in the bathing solution and co-applied with glutamate, is increased in half log units until the maximum effect was seen. Data collected in this manner are fit to the Hill equation, yielding an EC 50 value, indicative of the potency of the test compound. Reversibility of test compound activity is determined by assessing control glutamate 1 mM responses. Once the control responses to the glutamate challenge are re-established, the potentiation of these responses by 100 μM cyclothiazide is determined by its inclusion in both the bathing solution and the glutamate-containing solution. In this manner, the efficacy of the test compound, relative to that of cyclothiazide can be determined.
