Description: SUBSTITUTED THIOACETAMIDES FIELD OF THE INVENTION The present invention is related to chemical compositions, processes for the preparation thereof and uses of the composition. Particularly, the present invention relates to compositions that include substituted thioacetamides, and their use in the treatment of diseases, including treatment of sleepiness, promotion of wakefulness, treatment of Parkinson's disease, cerebral ischemia, stroke, sleep apneas, eating disorders, stimulation of appetite and weight gain, treatment of attention deficit hyperactivity disorder ("ADHD"), enhancing function in disorders associated with hypofunctionality of the cerebral cortex, including, but not limited to, depression, schizophrenia, fatigue, in particular, fatigue associated with neurologic disease, such as multiple sclerosis, chronic fatigue syndrome, and improvement of cognitive dysfunction. BACKGROUND OF THE INVENTION The compounds disclosed herein are related to the biological and chemical analogs of modafinil. Modafinil, C 15 H 15 NO S, also known as 2-(benzhydrylsulfinyl) acetamide, or 2-[(diphenylmethyl) sulfinyl] acetamide, is a synthetic acetamide derivative with wake-promoting activity, the structure of which has been described in French Patent No. 78 05 510 and in U.S. Patent No. 4,177,290 ('290), and which has been approved by the United States Food and Drug Administration for use in the treatment of excessive daytime sleepiness associated with narcolepsy. Modafinil has been tested for treatment of several behavioral conditions in combination with various agents including apomorphine, amphetamine, reserpine, oxotremorine, hypnotics, yohimbine, 5-hydroxytryptophan, and monoamine oxidase inhibitors, as described in the cited patents. A method of preparation of a racemic mixture is described in the '290 patent and a method of preparation of a levorotatory isomer is described in U.S. Patent No. 4,927,855 (both incorporated herein by reference). The levorotatory isomer is reported to be useful for treatment of hypersomnia, depression, Alzheimer's disease and to have activity towards the symptoms of dementia and loss of memory, especially in the elderly. The primary pharmacological activity of modafinil is to promote wakefulness. Modafinil promotes wakefulness in rats (Touret et al., 1995; Edgar and Seidel, 1997), cats (Lin et al., 1992), canines (Shelton et al., 1995) and non-human primates (Hernant et al, 1991) as well as in models mimicking clinical situations, such as sleep apnea (English bulldog sleep disordered breathing model) (Panckeri et al, 1996) and narcolepsy (narcoleptic canine) (Shelton et al, 1995). Modafinil has also been described as an agent with activity in the central nervous system, and as a useful agent in the treatment of Parkinson's disease (U.S. Patent No. 5,180,745); in the protection of cerebral tissue from ischemia (U.S. Patent No. 5,391,576); in the treatment of urinary and fecal incontinence (U.S. Patent No. 5,401,776); and in the treatment of sleep apneas and disorders of central origin (U.S. Patent No. 5,612,379). U.S. Patent No. 5,618,845 describes modafinil preparations of a defined particle size less than about 200 microns. In addition, modafinil may be used in the treatment of eating disorders, or to promote weight gain or stimulate appetite in humans or animals (US Provisional Patent Application No. 60/150,071, incorporated herein by reference), or in the treatment of attention deficit hyperactivity disorder (ADHD), or fatigue, especially fatigue associated with multiple sclerosis (US Provisional Patent Application No. 60/149,612, incorporated herein by reference). Several published patent applications describe derivative forms of modafinil and the use of modafinil derivatives in the treatment of various disorders. For example, PCT publication WO 99/25329 describes analogs of modafinil in which the phenyi groups are substituted with a F, CI, Br, CF 3 , NO 2 , NH 2 , C C 4 alkyl, Cι-C alkoxy, or methylenedioxy, and in which the amide is substituted with OH, Cι-C alkyl, - hydroxyalkyl, or a CrC 4 hydrocarbon radical. These compositions are described as being useful for treating drug-induced sleepiness, especially sleepiness associated with administration of morphine to cancer patients. Similarly, U.S. Pat. No. 4,066,686 describes beirzhydrylsulphinyl derivatives, including modafinil derivatives with an extended alkyl chain between the sulfinyl and carbonyl groups and where NR3R is NHOH. These compounds are described as being useful in therapy for treating disturbances of the central nervous system. PCT publication WO 95/01333 describes modafinil derivatives that are useful for modifying feeding behavior. The modifications to modafinil described include a chloro group at the 3 position of one of the phenyi groups, and a pyridyl substituted for the second phenyi, substitution of one or two methyl groups for hydrogens at the 2-carbon position, the amide hydrogens may be substituted with one or two groups selected from H, a pyridyl-methyl or ethyl groups, and further where the sulfur may not be oxidized. PCT publication WO 95/01171 also describes modified modafinil compounds that are said to be useful for modifying eating behavior. The described compounds include substitutions of 4-fluoro-, 3-fluoro-, and 4 chloro- in a first phenyi group and 4- fluoro- or 3-fluoro- substitutions in the second phenyi. Also described are substitutions in which the amide contains substitutions with an OH or isopropyl group. Terauchi, H, et al. described nicotinamide derivatives useful as ATP-ase inhibitors (Terauchi, H, et al, J Med. Chem., 1991, 40, 313-321). In particular, several N-alkyl substituted 2-(Benzhydrylsulfinyl) nicotinamides are described. U.S. Pat. Nos. 4,980,372 and 4,935,240 describe benzoylaminophenoxybutanoic acid derivatives. In particular, sulfide derivatives of modafinil containing a phenyi and substituted phenyi linker between the sulfide and carbonyl, and a substituted aryl in the terminal amide position, are disclosed. Other modafinil derivatives have been disclosed wherein the terminal phenyi groups are constrained by a linking group. For example, in U.S. Pat. No. 5,563,169, certain xanthenyl and thiaxanthenyl derivatives having a substituted aryl in the terminal amide position are reported. Other xanthenyl and thiaxanthenyl derivatives are disclosed in Annis, I; Barany, G. Pept. Proc. Am. Pept. Symp. 15 th (Meeting Date 1997) 343-344, 1999 (preparation of a xanthenyl derivative of Ellman's Reagent, useful as a reagent in peptide synthesis); Han, Y.; Barany, G. J Org. Chem., 1997, 62, 3841-3848 (preparation of S-xanthenyl protected cysteine derivatives, useful as a reagent in peptide synthesis); and El-Sakka, LA., et al. Arch. Pharm. (Weinheim), 1994, 327, 133-135 (thiaxanthenol derivatives of thioglycolic acid). Thus, there is a need for novel classes of compounds that possess beneficial properties. It has been discovered that a class of compounds, referred to herein as substituted thioacetamides, are useful as agents for treating or preventing diseases or disorders, including treatment of sleepiness, promotion of wakefulness, treatment of Parkinson's disease, cerebral ischemia, stroke, sleep apneas, eating disorders, stimulation of appetite and weight gain, treatment of attention deficit hyperactivity disorder, enhancing function in disorders associated with hypofunctionality of the cerebral cortex, including, but not limited to, depression, schizophrenia, fatigue, in particular, fatigue associated with neurologic disease, such as multiple sclerosis, chronic fatigue syndrome, and improvement of cognitive dysfunction. The present invention is directed to these, as well as other, important ends. SUMMARY OF THE INVENTION One aspect of the present invention provides, in part, various novel substituted thioacetamides.

For example, the amino acid side chain substituents of the compounds of formula (I), (I-A), (II), or (II -A) can be substituted with protecting groups such as benzyloxycarbonyl or t- butoxycarbonyl groups. Protecting groups are known per se as chemical functional groups that can be selectively appended to and removed from functionalities, such as hydroxyl groups and carboxyl groups. These groups are present in a chemical compound to render such functionality inert to chemical reaction conditions to which the compound is exposed. Any of a variety of protecting groups may be employed with the present invention. Preferred protecting groups include the benzyloxycarbonyl ("Cbz") group, the tert-butyloxycarbonyl ("Boc") group, and the tosyl (p-toluensulfonyl, "Tos") group. Other preferred protecting groups according to the invention may be found in Greene, T.W. and Wuts, P.G.M., Protective Groups in Organic Synthesis 2d. Ed., Wiley & Sons, 1991. Compounds of the present invention may be prepared as outlined in the following schemes. The reagents and starting materials are commercially available, or readily synthesized by well-known techniques by one of ordinary skill in the arts. All substituents, unless otherwise indicated, are as previously defined. A general synthetic procedure is set forth in Scheme A for preparing the compounds of formula (I) [wherein Y=C(R J )(R 2 ) and m, n=0] or (I-A): Scheme A b Step 3 Amidation Optional Step 4 Oxidation f Scheme A, step 1: Synthesis of compounds of general structure c: In step la, the appropriate aryl halide a undergoes a metal exchange reaction with an organometallic compound to give the corresponding metalloaryl compound. For example, an appropriate haloaromatic or haloheteroaromatic (compound a) is reacted with an appropriate alkyl lithium compound in an aprotic solvent at a temperature -78 °C. An appropriate haloaromatic or haloheteroaromatic compound is one where Arj; is as defmed in the final product. An appropriate alkyl lithium compound is one that effects a metal-halogen exchange. In step lb, an appropriate aryl aldehyde b is added to the previously formed metalloaryl compound to give desired di-aryl alcohol c. For example, an appropriate aromatic aldehyde or heteroaromatic aldehyde (compound b) in an aprotic solvent is added to reaction product of step la. An appropriate heteroaromatic aldehyde is one where Ar 2 is as defined in the final product. Upon completion, the reaction mixture is quenched by an appropriate quenching agent and the product, compound c, is isolated by conventional methods commonly employed by those skilled in the art. For example, a cooled (-70 °C to -78 °C) solution of an appropriate haloaromatic or haloheteroaromatic (compound a) in dry ether is reacted with n-butyllithium (1.1 eqv). After stirring for an additional period of time to allow the completion of halogen-metal exchange reaction, the next reactant, an appropriate heteroaromatic aldehyde (compound b) in ether is slowly be added to the reaction flask. Stirring is continued for an additional 2-3 h at the low temperature. The cooling bath is removed and the reaction mixture is slowly allowed to come to ambient temperature, followed by quenching, preferably by a saturated NH 4 C1 solution. The mixture is extracted into an organic solvent (ether or ethyl acetate). The organic layer is washed with brine, dried (MgSO 4 or Na 2 SO 4 ) and concentrated to give a crude product. Purification is achieved by employing known purification techniques (preferably by column cliromatography and/or recrystallization) to provide pure compounds c. The method is an adaptation from a procedure previously described by Gronowitz, S.; Eriksson, B. Arkiv Kemi 1963, 335, incorporated herein by reference in its entirety. Alternatively, this class of compounds wherein Ari is the same as Ar 2 may be generated by treatment of two equivalents of an appropriate haloheteroaromatic with two equivalents of n-butyllithium, followed by one equivalent of ethyl formate as described by Nenajdenko, V. G.; Baraznenok, I. L.; Balenkova, E. S. J Org. Chem. 1998, 6132, incorporated herein by reference in its entirety. Scheme A, step 2: Synthesis of compounds of general structure d: In step 2a, the alcohol moiety of compound c is converted to the corresponding thiol. The thiol, in step 2b, undergoes a substitution reaction with an appropriate halogen-substituted alkylcarboxylic acid of structure Br-(CH 2 ) m -Y-(CH 2 ) n -COOH, to generate compound d. For example, di-aryl alcohol c is reacted with thiourea in presence of an acid to convert it to a thiouronium moiety that is subsequently hydrolyzed in the presence of an alkaline base and reacted with the appropriate halogen-substituted alky Icarboxy lie acid to generate compound d (step 2b). An appropriate acid derivative is one in which m, n, Y are as defined in the final product. For example, in step 2a, an appropriate amount of thiourea is taken into 48% HBr and water. The mixture is warmed (preferably to 60 - 70 °C), followed by addition of compound c. The temperature of the reaction mixture is elevated (preferably to 90-95 °C) and the stirring is continued for an additional period of time for completion of the reaction. The reaction mixture is cooled to room temperature (in some cases, an ice-bath might be needed) and the precipitated solid should be filtered and thoroughly washed with water. In step 2b, the wet solid from the previous step is taken into additional water and treated with an aqueous base, preferably sodium hydroxide solution. The mixture is warmed (preferably to 70 - 80 °C, but in some cases a higher temperature might be needed) and to it an appropriate amount of halogen-substituted alkylcarboxylic acid derivative in water ( or in some cases, an alcoholic solvent) is added. The reaction mixture is maintained at an elevated temperature (preferably 100 - 110 °C) for an appropriate period of time, cooled, taken into water and washed with an organic solvent (preferably ether). The basic aqueous layer is acidified with an inorganic acid solution (e.g. aqueous HCI solution). The aqueous (acidic) solution is then extracted several times into an organic solvent (e.g. ether or ethyl acetate). The combined organic layer is washed with brine, dried (MgSO 4 or Na 2 SO 4 ) and concentrated to give the crude product that may be used directly in the next step. However, purification could be achieved by employing known purification techniques (e.g. recrystallization) to provide pure compound d. The method is an adaptation from a procedure previously described in U.S. Pat. No. 4,177,290, incorporated by reference herein in its entirety. Scheme A, step 3: Synthesis of compounds of general structure e: In step 3 a, the carboxylic acid is converted into appropriate acid derivative, which is then reacted with an appropriate amine to give compound e. For example in step 3 a, compound d can be converted to the corresponding acid chloride, or the corresponding activated ester. The acid chloride can be obtained by reacting compound d with thionyl chloride in an aromatic hydrocarbon solvent in refluxing condition. Alternatively, the activated ester can be obtained by use of various agents known in the art, such as 2-(lH- Benzotriazol-l-yl)-l,l,3,3-tetramethyluronium tetrafluoroborate ("TBTU"), N- methylmorpholine ("ΝMM") and dimethyl formamide ("DMF"). In step 3b, the product of step 3 a is reacted with an appropriate amine of structure ΝHR 3 Ri to give the desired compound e. An appropriate amine is one which correlates to R 3 and j as defined in the final product. For example, a solution of an appropriate carboxylic acid (compound d) in either benzene or toluene is brought to reflux temperature and to it is slowly added an appropriate amount of thionyl chloride. The mixture is refluxed xintil the disappearance of starting material (as evidenced by analytical techniques), cooled and solvent removed. The resulting residue is taken into an appropriate organic solvent (preferably tetrahydrofuran or methylene chloride) and treated with ammonia gas (or 28% aqueous ammonia hydroxide solution) or an appropriate amine. The reaction mixture is then partitioned between water and an organic solvent (preferably ethyl acetate). The separated organic layer is washed with water, dilute acid, dilute base and brine, dried over a drying agent (e.g. MgSO 4 or Na 2 SO ) and concentrated to give the crude product that may be purified by column chromatography and/or recrystallization to produce compound e. Scheme A, optional step 4: Synthesis of compounds of general structure f: Compounds of structure e may optionally be oxidized to generate compounds of structure f. Thus, compound f is prepared by reacting compound e in an appropriate solvent with an appropriate oxidizing agent. An appropriate oxidizing agent is one that oxidizes the sulfide group of compound e. The corresponding product is isolated and purified by methods well known in the art. For example, to a cooled (-15 °C to -25 °C) solution of compound e in an organic solvent (preferably methylene chloride or chloroform), an appropriate oxidizing agent (e.g. m-chloroperoxybenzoic acid ["rø-CPBA"], 1 equivalent) in the same solvent is slowly added. Stirring is continued at low temperature until the disappearance of the starting material, as evidenced by various analytical techniques. The reaction mixture is then thoroughly washed with a saturated sodium bicarbonate solution, water and brine, respectively, dried over a drying agent (e.g. MgSO 4 or Na 2 SO 4 ) and concentrated. The desired product (compound f) is purified, if needed, by employing known purification teclmiques (preferably by column cliromatography and/or recrystallization). In some cases, the oxidation is performed by employing 50% H 2 O 2 in glacial acetic acid solvent. A general synthetic procedure is set forth in Scheme B for preparing the compounds of formula (II) [wherein ring A is phenylene; Y=C(Ri)(R 2 ) and m, n, r, s=0] and (II-A): Scheme B cc Step 2 Amidation Optional Step 3 Oxidation Scheme B, steps 1, 2, and 3: Synthesis of compounds of general structure dd, ee and ff. The synthetic steps in Scheme B involve the same multistep general method described in Scheme A, wherein Scheme B, steps 1-3 corresponds to Scheme A, steps 2- 4, respectively.

The synthetic steps in Scheme C, steps 1 and 2 involve the same multistep general method described in Scheme A, steps 2-3, respectively to give compounds of structure eee. Scheme C, step 3 : Synthesis of compounds of general structure ff. The amide moiety in compound eee is converted to corresponding thioamide moiety fff with an appropriate sulfur-transfer reagent. For example, a mixture of compound eee and Lawesson's reagent (1.05 eqv) in a suitable solvent (dimethoxyethane or tetraliydrofuran) is heated to reflux until the disappearance of the starting material. After cooling, the' desired product (compound fff) is obtained by employing known purification techniques (preferably by column chromatography and/or recrystallization). Scheme C, step 4: Synthesis of compounds of general structure ggg. The thioamide moiety in compound fff is cyclized to the corresponding thiazole moiety. For example, a mixture of compound fff and an appropriate bromomethyl ketone (1.1 eqv) in a suitable solvent (e.g. ethanol) is heated to reflux until the disappearance of the starting material. After cooling, the desired product (compound ggg) is obtained by employing known purification techniques (preferably by column chromatography and/or recrystallization). Scheme C, steps 5-6: Synthesis of compounds of general structure hhh and iii. The synthetic steps in Scheme C, steps 5 and 6 involve the same multistep general method described in Scheme A, steps 3 and 4, respectively to give compounds of structure hhh and iii. A general synthetic procedure is set forth in Scheme D for preparing the compounds of formula (II- A), wherein n=0 and Y is Scheme D Step 2 Amidation Scheme D, steps 1-6: Synthesis of compounds of general structure hhhh and iiii.

In the first step, an appropriate mercaptolactam 59 is reacted with an appropriate diarylmethanol, compound 27, in the presence of a weak acid, in order to affect nucleophilic displacement at the methanol carbon to form the corresponding thioether. The appropriate mercaptolactam 59 and appropriate diaryl- or diheteroarylmethanol, 27 are ones in which ATT , AT 2 , R 2 and Ri are as defined in the final product. In the second step, the thioether formed in the first step is optionally oxidized with an appropriate oxidizing agent to provide compound 60. An appropriate oxidizing agent is one that oxidizes the thioether to its corresponding sulfoxide or sulfone. A synthetic procedure is set forth in Reaction Scheme F for preparing compounds of formula (II- A), wherein Ri or R 2 can be taken together with either R 3 or R 4 to form a 3-7 member heterocyclic ring. A similar procedure may be utilized to prepare the corresponding compounds of formula (II- A). The subsequently formed ring is represented in Scheme E by "G".

It is understood that Ri may be also be taken with Rt to form ring "G", or R 2 may be also be taken with R 3 to form ring "G", or R 2 may be also be taken with Rφ to form ring "G". The reagents and starting materials are commercially available, or readily synthesized by well-known techniques by one of ordinary skill in the arts.

Example 93: Demonstration of Wake-promoting activity of compoxmd 1-9. The methodology utilized is as described by Edgar and Seidel, Journal of Pharmacology and Experimental Therapeutics, 283:757-769, 1997, incorporated herein in its entirety by reference. Animal Surgery. Adult, male Wistar rats (275-320g from Charles River Laboratories, Wilmington, MA) were anesthetized (Nembutal, 60mg/kg, ip) and surgically prepared with implants for recording of chronic EEG and EMG recording. The EEG implants consisted of stainless steel screws (2 frontal (+3.9 AP from bregma, +2.0ML) and 3 occipital (-6.4 AP, ± 5.5ML). Two Teflon-coated stainless steel wires were positioned under the nuchal trapezoid muscles for EMG recording. All leads were soldered to a miniature connector (Microtech, Boothwyn, PA) and gas sterilized with ethylene oxide before surgery. The implant assembly was affixed to the skull by the combined adhesion of the EEG recording screws, cyanoacrylate applied between the hermetically sealed implant connector and skull and dental acrylic. An antibiotic (Gentamycin) was administered for 3 to 5 days postsurgery. At least 3 weeks were allowed for postsurgical recovery. Recording environment. Rats were housed individually within specially modified Nalgene microisolator cages equipped with a low-torque slip-ring commutator (Biella Engineering, Irvine, CA) and a custom polycarbonate filter-top riser. These cages were isolated in separate, ventilated compartments of a stainless steel sleep-wake recording chamber. Food and water were available ad libitum and ambient temperature was 24 + 1 °C. A 24-h light-dark cycle (light/dark 12-12-) was maintained throughout the study by 4-watt fluorescent bulbs located approximately 5cm from the top of each cage. Light intensity was 30 to 35 lux at midlevel inside the cage. Animals were undisturbed for 3 days both before and after the treatments. Automated data collection. Sleep and wake stages were determined with SCORE, a microcomputer-based sleep-wake and physiological monitoring system. SCORE™design features, validation in rodents and utility in preclinical drug evaluation have been reported elsewhere (Nan Gelder, et al., 1991; Edgar, et ah, 1991, 1997; Seidel, et al, 1995, incorporated by reference herein in their entirety). In the present study, the system monitored amplified (X 10,000) EEG (bandpass, 1-30 Hz; digitization rate, 100 Hz) and integrated EMG (bandpass, 10-100 Hz, root mean square integration). Arousal states were classified on-line as ΝREM sleep, REM sleep, wake or theta-dominated wake every 10s by use of EEG period and amplitude feature extraction and ranked membership, algorithms. Individually taught EEG-arousal-state templates and EMG criteria differentiated REM sleep from theta-dominated wakefulness (Welsh, et al, 1985, incorporated by reference herein in its entirety). Data quality was assured by frequent online inspection of the EEG and EMG signals. Raw data quality and sleep-wake scoring was scrutinized further by a combination of graphical and statistical assessments of the data as well as visual examination of the raw EEG wave forms and distribution of integrated EMG values. Drug administration and study design. Compound 1-9 was suspended in sterile 0.25% methylcellulose (pH=6.2; Upjohn Co., Kalamazoo, MI) or methylcellulose vehicle alone was injected intraperitoneally in a volume of lml/kg. Sample size (n) was 13 animals per treatment group. EEG spectral analysis. Each 10-s epoch of raw EEG signal was digitized (100 Hz) for 24h and wakefulness was scored as described previously by Edgar and Seidel (1996), incorporated by reference herein in its entirety. Data analysis and statistics. The principal variable recorded was minutes per hour of wake. Treatment groups were compared post-treatment by repeated-measures AΝONA. In the presence of a significant main effect, Dunnett's contracts (a = 0.05) assessed differences between active treatment groups and vehicle controls, unless otherwise specified. Results. Figure 1 illustrates degree of wakefulness in rats treated at tixne zero with either 100 mg/kg, ip of coxnpoxmd 1-9 (solid line) or methylcellulose vehicle (stippled line). Compound 1-9 produced wakefulness beyond that observed in vehicle- treated animals that lasted until approximately 110 minutes following administration. Example 94: Demonstration of Wake-promoting activity of compoxmd 11-23. The methodology utilized is based on that described by Edgar and Seidel, Journal of Pharmacology and Experimental Therapeutics, 283:757-769, 1997, and incorporated herein in its entirety by reference. Animal Surgery. Adult, male Wistar rats (275-320g from Charles River Laboratories, Wilmington, MA) were anesthetized (Nembutal, 45mg/kg, ip) and surgically prepared with implants for recording of chronic EEG and EMG recording. The EEG implants were made from commercially available components (Plastics One, Roanoke, VA). EEG's were recorded from stainless steel screw electrodes (2 frontal (+3.0 mm AP from bregma, ±2.0 mm ML) and 2 occipital (-4.0 mm AP, ±2.0 mm ML)). Two Teflon-coated stainless steel wires were positioned under the nuchal trapezoid muscles for EMG recording. All electrode leads were inserted into a connector pedestal and the pedestal, screws, and wires affixed to the skull by application dental acrylic. Antibiotic was administered post surgically and antibiotic cream was applied to the wound edges to prevent infection. At least 1 week elapsed between surgery and recording. Animals are tested for approximately 6-8 weeks and then sacrificed. Recording environment. Postsurgically, rats were housed individually in an isolated room. At least 24 hrs. prior to recording, they were placed in Nalgene containers (31 x 31 x 31 cm) with a wire-mesh top, and entry to the room was prohibited until after recording had ended except for dosing. The containers were placed on a 2- shelf rack, 4 per shelf. Food and water were available ad libitum, ambient temperature was 21°C, and humidity was 55%>. White-noise was provided in the background (68db inside the containers) to mask ambient sounds. Fluorescent overhead room lights were set to a 24 hr. light/dark cycle (on at 7 AM, off at 7 PM). Light levels inside the containers were 38 and 25 lux for the top and bottom shelves respectively. Data acquisition. EEG and EMG signals were led via cables to a commutator (Plastics One) and then to pre-amplifiers (model 1700, A-M Systems, Carlsborg, WA). EEG and EMG signals were amplified (10K and IK respectively) and bandpass filtered between 0.3 and 500 Hz for EEG, and betweenlO and 500 Hz for EMG. These signals were digitized at 128 samples per second using ICELUS sleep research software (M. Opp, U. Texas; see Opp, Physiology and Behavior 63:67-74, 1998, and Imeri, Mancia, and Opp, Neuroscience 92:745-749, 1999, incorporated by reference herein in their entirety) running under Labview 5.1 software and data acquisition hardware (PCI-MIO- 16E-4; National Instruments, Austin, TX). On the day of dosing, data was recorded from 11 AM to 6 PM. Sleep / wake scoring. Sleep and wake stages were deteπnined manually using ICELUS software. This program displays the EEG and EMG data in blocks of 6 sec. along with the EEG-FFT. Arousal state was scored as awake (WAK), rapid eye- movement (REM), or slow-wave or non-REM sleep (NREM) according to visual analysis of EEG frequency and amplitude characteristics and EMG activity (Opp and Krueger, American Journal of Physiology 266:R688-95, 1994; Van Gelder, et al., 1991; Edgar, et al., 1991, 1997; Seidel, et al, 1995, incorporated by reference herein in their entirety). Essentially, waking activity consists of relative low-amplitude EEG activity with relatively lower power in the lower frequency bands from 0.5 - 6 Hz, accompanied by moderate to high level EMG activity. In a particular waking state ("theta-waking"), EEG power can be relatively focused in the 6-9 Hz (theta) range, but significant EMG activity is always present. NREM sleep is characterized by relative high-amplitude EEG activity with relatively greater power in the low frequency bands from 0.5 - 6 Hz, accompanied by little or no EMG activity. REM sleep is characterized by moderate and constant amplitude EEG focused in the theta (6-9 Hz range), similar to waking theta, but with no EMG activity. Drug administration and study design. Compounds were evaluated on groups of 4 or 8 rats which were tested in 2 sessions at least 2 days apart. Initial studies used a crossover design, such that rats received either vehicle or test compound during each session. Animals were pseudo-randomized so that they did not receive the same drug twice. Compound 11-23 was suspended in sterile 0.25% methylcellulose (pH=6.2; Upjohn Co., Kalamazoo, MI) at 30 mg/ml. This study was carried out on 8 rats which were tested in 2 sessions 5 days apart (overall, 7 rats received compound 11-23 and 6 methylcellulose vehicle). Dosing was carried out at noon, while the rats were predominantly asleep. Each rat was lifted out of its container, given an intraperitoneal. injection in a volume of 3.33 ml/kg, and replaced. Dosing required approximately 8 minutes. Data analysis and statistics. The principal outcome measure was minutes per hour of wakefulness. The primary outcome measure for purposes of determining activity in these experiments consists of the total integrated wake time for the first 3 hours post dosing relative to vehicle control. Thus, vehicle treated animals typically average 20% wake time dxiring the recording period, or a total of 0.2 * 180 = 36 min. A 2-tailed, unpaired t-test (Statview 5.0, SAS Institute, Inc., Cary, NC) was performed on the wake time values for drug and vehicle treated animals, and compounds with p<0.05 were deemed significantly wake-promoting. Waking activity was also evaluated for successive half-hour periods beginning with the time of dosing, and individual t-tests performed at each time point to establish the duration of significant wake-promoting activity. Results. Figure 2 illustrates degree of wakefulness in rats treated at noon with either 100 mg/kg, ip. of compound 11-23 (solid triangles) or methylcellulose vehicle (open circles). Each point represents the mean percent of time awake for the succeeding half hour. The dosing procedure produced a transient (~20 min.) period of elevated wakefulness in both treatment groups compared to pre-dosing baseline activity. Compoxmd 11-23 produced significantly greater wakefulness than that observed in vehicle-treated animals (p<0.05). References.
