Abstract

The present invention provides 6-substituted 2,3,4,5-tetrahydro-1H-benzo[d]azepines of Formula I as selective 5-HT2C receptor agonists for the treatment of 5-HT2C associated disorders including obesity, obsessive/compulsive disorder, depression, and anxiety:I where:R6 is -C=C-R10, -O-R12, -S-R14, or -NR24R25;and other substituents are as defined in the specification.

Description

2,3,4, 5-TETRAHIDRO-lH-BENZO [D] AZEPINAS 6-SUBSTITUTED AS AGENTS OF THE 5-HT2c RECEPTOR The serotonin neurotransmitter (5-hydroxytryptamine, 5-HT) has a rich pharmacology resulting from a heterogeneous population of at least seven receptor classes. Serotonin class 5-HT2c is further subdivided into at least three subtypes, designated 5-HT2A, 5-HT2B, and 5-HT2c. The 5-HT2c receptor has been isolated and characterized (Julius, et al., US Patent No. 4,985,352), and it has been reported that transgenic mice lacking the 5-HT2c receptor show attacks and an eating disorder resulting in increasing consumption of food (Julius et al., US Patent No. 5,698,766). The 5-HT2c receptor has also been linked to several other neurological disorders including obesity (Vickers et al., Psychopharmacology, 167: 274-280 (2003)), hyperphagia (Tecott et al., Nature, 374: 542-546 (1995)), obsessive-compulsive disorder (Martin et al., Pharmacol.
Biochem. Beba., 71: 615 (2002); Chou-Green et al., Physiology & Behavior, 78: 641-649 (2003)), depression (Leysen, Kelder, Trends in Drug Research II, 29: 49-61 (1998)), anxiety (Curr Opin, Invest Drugs 2 (4), p.317 (1993)), substance abuse, sleeping disorders (Frank et al., Neuropsychopharmacology 27: 869-873 (2002)), hot flushes (EP 1213017 A2), epilepsy (Upton et al., Eur. J. Pharmacol., 359: 33 (1998); Fitzgerald, Ennis, Annual Reports in Medicinal Chemistry, 37 : 21-30 (2002)), and hypogonadism (Curr Opin, Invest Drugs 2 (4), p.317 (1993)). Certain substituted 2, 3, 4, 5-tetrahydro-lH-benzo [d] azepine compounds have been described as useful therapeutics such as for example: U.S. Pat. No. 4,265,890 discloses certain substituted 2, 3, 4, 5-tetrahydro-lH-benzo [d] azepine compounds as dopamine receptor antagonists for use as antipsychotics and antiemetics, among others.
EP 0 285 287 describes certain substituted 2,3,4,5-tetrahydro-lH-benzo [d] azepine compounds for use as agents for treating gastrointestinal motility disorders, among others. WO 93/03015 and WO 93/04686 disclose certain substituted 2, 3, 4, 5-tetrahydro-lH-benzo [d] azepine compounds as alpha-adrenergic receptor agonists for use as agents for treating hypertension and cardiovascular diseases in which changes in vascular resistance are desirable, among others. WO 02/074746 A1 discloses certain substituted 2, 3, 4, 5-tetrahydro-lH-benzo [d] azepine compounds as 5-HT2c agonists for the treatment of hypogonadism, obesity, hyperphagia, anxiety, depression, disorders of the sleep, among others.
WO 03/006466 A1 discloses certain substituted tricyclic hexahydroazepinoindole and indoline compounds as 5-HT ligands and consequently their utility to treat diseases where modulation of 5-HT activity is desired. High affinity 5-HT2c receptor agonists will provide useful therapeutics for the treatment of the disorders associated with the above-mentioned 5-HT2 receptor including obesity, hyperphagia, obsessive / compulsive disorder, depression, anxiety, substance abuse, sleep disorder , hot flashes, and hypogonadism. High affinity 5-HT2c receptor antagonists that are also selective for the 5-HT2c receptor will provide such therapeutic benefit without the undesirable adverse events associated with current therapies. The selectivity achieved by the 5-HT2c receptor, particularly as against the 5-HT2ñ and 5-HT2B receptors, provides a difficulty in the design of 5-HTc agonists. The 5-HT2 receptor agonists have been associated with problematic hallucinogenic adverse events. (Nelson et al., Naunyn-Schmiedeberg's Arch. Pharm., 359: 1-6 (1999)). 5-HT2B receptor agonists have been associated with cardiovascular related adverse events, such as valvular disease. (Setola et al., Mol.Pharmacology, 63: 1223-1229 (2003), and references cited therein).
Previous references for substituted 2,3,4,5-tetrahydro-lH-benzo [d] azepine compounds as potential therapeutics have predominantly mentioned their uses as alpha adrenergic and / or dopaminergic modulators. Adrenergic modulators are frequently associated with the treatment of cardiovascular diseases (Frishman, Kotob, Journal of Clinical Pharmacology, 39: 7-16 (1999)). Dopamine receptors are primary targets in the treatment of schizophrenia and Parkinson's disease (Seeman, Van Tol, Trends in Pharmacological Sciences, 15: 264-270 (1994)). It will be appreciated by those skilled in the art that selectivity, as against these and other physiologically important receptors, will generally also be preferred characteristics for therapeutics for the specific treatment of disorders associated with 5-HT 2c as described above.

Known optical rotations are designated by (+) and (-) for dextrorotatory and levorotatory, respectively. Where a chemical compound is resolved in its isomers, but with absolute configurations or optical rotations that are not determined, the isomers are arbitrarily designated as isomer 1, isomer 2, etc. While all enantiomers, diastereomers, and mixtures thereof, are contemplated within the present invention, preferred embodiments are simple enenatiomers and simple diastereomers. It will generally be understood by those of experience in this art, that the compounds intended for use in pharmaceutical compositions are routinely, but not necessarily, converted to a salt form in efforts to optimize such characteristics as handling properties, stability, pharmacokinetics, and / or bioavailability, etc. Methods for converting a compound to a given salt form are well known in the art (see, for example, Berge, SM, Bighiey, LD, and Monkhouse, DC, J. Pharm, Sci., 66: 1, (1977) ). In that the compounds of the present invention are amines and therefore based on the natural, they readily react with a wide variety of pharmaceutically acceptable organic and inorganic acids to form pharmaceutically acceptable acid addition salts therewith. Such salts are also embodiments of this invention. Typical inorganic acids used to form such salts include hydrochloric, hydrobromic, hydroiodic, nitric, sulfuric, phosphoric, hypophosphoric, metaphosphoric, pyrophosphoric, and the like. Salts derived from organic acids, such as mono- and dicarboxylic aliphatic acids, phenyl-substituted alkanoic acids, hydroxyalkanoic and hydroxyalkanedioic acids, aromatic acids, aliphatic acids and aromatic sulfonic acids, may also be used. Such pharmaceutically acceptable salts thus include chloride, bromide, iodide, nitrate, acetate, phenylacetate, trifluoroacetate, acrylate, ascorbate, benzoate, chlorobenzoate, dinitrobenzoate, hydroxybenzoate, methoxybenzoate, methylbenzoate, o-acetoxybenzoate, isobutyrate, phenylbutyrate, α-hydroxybutyrate, butino- 1,4-dicarboxylate, hexyne-1,4-dicarboxylate, caprate, caprylate, cinnamate, citrate, formate, fumarate, glycolate, heptanoate, hippurate, lactate, malate, maleate, hydroximelate, malonate, mandelate, nicotinate, isonicotinate, oxalate, phthalate, terephthalate, propiolate, propionate, phenylpropionate, salicylate, sebacate, succinate, suberate, benzenesulfonate, p-bromobenzenesulfonate, chlorobenzenesulfonate, ethylsulfonate, 2-hydroxyethyl sulfonate, methylsulfonate (mesylate), naphthalene-1-sulfonate, naphthalene-2-sulfonate, naphthalene -1,5-sulfonate, p-toluenesulfonate, xylene sulphonate, tartrate, and the like. It is well known that such compounds can form salts at various molar ratios with the acid to provide, for example, the salt of the hemi-acid, mono-acid, di-acid, etc. Where the process of salt formation, the acid is added in a specific stoichiometric ratio, unless otherwise analyzed to confirm, the salt is presumed, but not known, to form its molar ratio. Terms such as "(acid) / 'will be understood to mean that the molar ratio of the salt formed is not known and can not be presumed, as for example, but without limitation, (HC1) X and (methanesulfonic acid) x.

The compounds of the present invention are particularly selective for the 5-HT2c receptor compared to the other 5-HT receptor subtypes and specifically the 5-HT2a and 5-HT2B receptors. This selectivity is demonstrated in the following assays of agonist activity and receptor binding assays.
Assays of Agonist Astivity (G alpha q-GTP? [35S] Enlase assays) 5-HT2 receptors are functionally coupled to specific G proteins. The agonist activation of receptors coupled to the G protein 5-HT2 result in the ratio of GDP from the subunit to (G alpha q or G alpha i) of the G protein and the subsequent binding of GTP. The binding of the stable analog GTP? [35S] is an indicator of receptor activation (this is, agonist activity). The G-alpha q-GTP [35S] binding assay is used to determine the in vitro potency (EC5o) and maximum efficacy (Emax, normalized to the 5-HT response) of a test compound at the 5-HT2A receptors, 5-HT2B, and 5-HT2c. The area under the dose response curve (AUC) is also determined for each receptor subtype and is used to measure the selectivity of test compounds for the 5-HTc receptor on the 5-HT2a and 5-HT2B receptors, expressed as selectivity ratios (AUC 2C / 2A and AÜC 2C / 2B, respectively). The Selectivity relationships allow the evaluation of selectivity based on both power and efficiency. A measure of selectivity that incorporates both potency and efficacy at the 5-HT2c receptor, when compared to the 5-HT2a and 5-HT2B receptors, is considered important due to the adverse events associated with 5-HT2α agonist activity. and 5-HT2B (see introduction). Preparation of membranes; Stable AV12 cells transfected with the human 5-HT2a, 5-HT2B or 5-HT2c receptors are grown in suspension, harvested by centrifugation, the cell pellet is washed with phosphate buffered saline, pH 7.4, the cells are pelleted again, the supernatant is removed, the cell pelletization is frozen in dry ice and stored at -70 ° C. The pelletizing of reserve cells is thawed and resuspended in 50 mM Tris, pH 7.4, aliquots are formed in 1-2 mL volumes and refreezing at -70 ° C for subsequent tests. (As appreciated in the art, optimal amounts of the cell used per aliquot will vary with the individual transfected cell line used.) In one embodiment, the transfected 5-HT2a and 5-HT2c cells are typically used in about 6 x 108 cells per aliquot, while 5-HT2B cells are typically used in about 7.5 x 108 cells per aliquot). On the day of the assay, the membranes are thawed, the membranes are washed with assay buffer (50 mM Tris-HCl (pH 7.4), 10 mM MgCl2, 100 mM NaCl, and 0.2 mM EDTA), resuspended in solution buffer assay and incubate for 10 minutes at 37 ° C to hydrolyze any residual endogenous 5-HT. The membranes are again washed with assay buffer and resuspended in assay buffer at a concentration to provide aliquots of about 1-4x106 equivalent cells per well (typically about 1-2x106 equivalents of cells for assays with HT2a or 5-HT2c receptor assays and about 3-4x106 cell equivalents for assays with 5-HT2B receptor assays). The cells are homogenized with a tissue mill and the homogenate is used directly in the assay as described below. G-alpha q-GTP binding assays [35S]: The immunoadsorption scintillation proximity assay (ISPA) of the [35S] -GTP? S to G alpha binding is modified from published conditions (DeLapp et al, JPET 289 (1999) 946-955). The test compounds are dissolved in DMSO and diluted in assay buffer to provide a range of concentrations to generate a concentration response curve. In the wells of a 96-well microtiter plate, the diluted test compound, GDP (0.1 μM final concentration), and [35 S] -GTPγS (between 0.5 and 0.1 nM final concentration) are mixed. An aliquot of membrane is added to the incubation mixture and the plates are mixed to initiate stimulation of the nucleotide exchange agonist (final volume of 200 μl). The microtiter plates are incubated for 30 min. At room temperature. The incubation with IGEPAL® CA-630 detergent (0.27% final concentration) is switched off. The affinity-purified polyclonal rabbit anti-G alpha antibody (about 1-2 μg per well) is added, and the anti-rabbit Ig scintillation proximity test beads (Amersham, about 1.25 mg per well, 300 μl final volume). The plates are sealed and the mixture is incubated for 3 hours at room temperature. The microtiter plates are centrifuged briefly to palletize the beads. The binding of (GTP? [35S] is quantified by microtitre plate scintillation spectrometry ((Wallac Trilux MicroBeta ™ scintillation counter) Data Analysis: For each concentration response curve for a test compound to a receptor Given, the data is analyzed with the GraphPad Prism ™ software (v3.02; GraphPad Software, San Diego, CA) running on a personal computer with a Microsoft Windows OS®, by using a non-linear regression analysis curve that is adjusted to determine the EC5o and Emax (normalized to the 5-HT control curves) The area under the agonist concentration response curve (AUC) is determined with GraphPad Prism ™ by the trapezoidal method. Selectivity first, determine the AUC for the test compound for each subtype of the receptor as described above, Second, normalize the AUCs in each subtype of the receptor relative to the AUC determined for 5-HT in that The AUC normalized for a test compound to a given receptor is therefore expressed as a percentage of the AUC determined for 5-HT in that receptor. For example: Normalized AUC of 5HT2a = a = (AUC test compound in 5HT2 & amp; amp; X) 100% (AUC 5-HT in dHTa receptor) Normalized AUC of 5HT2B = a = (AUC test compound in 5E? 2B receptor) X 100% (AUC 5-HT in 5H? 2B receptor) AUC Normalized of 5HT2c = a = (AUC test compound in 5HT2C receptor) X 100 % (AUC 5-HT in 5HT2C receptor) Third, calculate the selectivity ratios for the test compound as follows: Selectivity ratio for the 5-HT2c receptor / 5-HT2a receptor (AUC2C / 2A) = c / a. Selectivity ratio for the 5-HT2c receptor / 5-HT2B receptor (AUC2C / 2B) = c / b. For reference purposes, the AUC 2C / 2A and AUC 2C / 2B for 5-HT are each 1.0. Similarly, the ratios for mCPP (meta-chlorophenylpiperazine) are tested and found to be 2.1 and 2.1 respectively. Representative compounds of the present invention are tested in the G alpha q-GTP? [35 S] assays for the 5-HT 2a, 5-HT 2B, and 5-HT 2c receptors essentially as described above and are found to be selective and highly selective agonists. potentiates of the 5-HT2C receptor with the EC50 typically less than or equal to 200 nM, and the ratios of AUC 2C / 2A and AUC 2C / 2B greater than 1.5. Preferred compounds are those with EC50 less than or equal to 100 nM, and AUC 2C / 2A and AUC 2C / 2B ratios greater than or equal to 2. 0. Those with EC50 less than or equal to 50nM, and ratios of AÜC 2C / 2A and AUC 2C / 2B greater than or equal to 3.0 are more preferred.
Ligand Enlase Assays The binding affinity of the ligand of the compounds of the present invention to the HT2C receptor subtype is measured essentially as described by Wainscott (Wainscott, et al., Journal of Pharmacology and Experimental Therapeutics, 276: 720- 727 (1996)). The data are analyzed by non-linear regression analysis in the response curves to the concentration using the four-parameter logistic equation described by DeLean (DeLean, et al., Molecular Pharmacology, 21, 5-16 (1982)). The IC 50 values are converted to the Ki values using the Cheng-Prusoff equation (Cheng, et al., Biochem. Pharmacol., 22, 3099-3108 (1973)). The representative compounds of the present invention are tested essentially as described above and are found to have an excellent affinity for the 5-HT 2C receptor with K 1. typically less than or equal to about 200 nM. Preferred compounds with those Ki less than or equal to about 100 nM. Those with Ki less than or equal to 50nM are more preferred. The affinities for other receptor subtypes can be easily determined by a light modification of the radioligand receptor binding assay described above using cells transfected with the desired receptor in place of cells transfected with the 5-HT2C receptor subtype and using a suitable radioligand. The binding affinities for the representative compounds of the present invention for a variety of receptors are determined in such assays and the compounds are found to have surprisingly higher affinity for the 5-HT2c receptor. The affinity for the 5-HT2c receptor is found to be significantly higher for other 5-HT receptor subtypes and markedly superior to the 5 HT2a and 5-HT2B receptor subtypes. Preferred compounds are those with an IC5o's equal to or greater than 300 nM for the alpha 1 and alpha2 adrenergic receptors and equal to or greater than 500 nM for the dopaminergic receptors Di and D2. The most preferred compounds are those with IC50 equal to or greater than 1000 nM for the adrenergic receptors alpha 1 and alpha 2 and the dopaminergic receptors Di and D2. Even more preferred are those compounds with IC50 's equal to or greater than 3000 nM for the alpha 1 and alpha 2 adrenergic receptors and the dopamine receptors Di and D2. For previous in vitro tests, the exemplified compounds are tested and found to have either an EC50 or a Ki value equal to or less than 50 nM and having AUC 2C / 2A and AUC 2C / 2B ratios greater than or equal to 2.0. The exemplified compounds are tested and found to have the ICso's of the alpha 1 and alpha 2 adrenergic receptor equal to or greater than 300 nM and the IC5o's of the dopaminergic receptor Da and D2 equal to or greater than 500 nM.
Rat Feeding Assays The ability of the compounds of the present invention to treat obesity is demonstrated by the test in feeding trials with acute and chronic rats. Animals: Long-Evans male rats (Harían Sprague-Dawley, Indianapolis, IN) are obtained that are approximately one hundred days old and have been kept on a high-calorie diet since weaning (fat calories; TD 95217, 40% Teklad , Madison, Wl). The rats are housed individually with a light cycle: 12 hr dark: 12 h (the lights are switched on from 10 p.m. to about 10 p.m.) and the rats are kept on the same diet (TD95217) with free access to water for about 1-2 weeks to acclimatize the rats to the environment. The rats are dosed orally with vehicle (10% acacia with 0.15% saccharin in water) once a day for at least 1 day (typically 1-2 days) to acclimate the rats to the procedures. The rats are randomly selected into groups so that each group has similar average body weights. Acute Calorimetric Feeding Test: At approximately 8:00 on the day of the test, each rat is weighed and transferred to the individual chambers of an open-circuit calorimetry system (Oxymax, Columbus Instruments International Corporation, Columbus, OH) with access free to feed (pre-weighed) and water and start measuring V02 and VC02. At approximately 10:00 h, the rats are dosed orally with the vehicle or test compound, returned to their calorimetry chambers and V02 and VC02 are continued to be measured at regular time intervals (approximately every hour). At approximately 8:00 a.m. the next day, the body weight of the rat and the remaining food are measured, assuming that the difference in weight of the food is equal to the mass of food consumed. The energy expenditure for 24 hours (EE) and the respiratory quotient (RQ) is calculated essentially as described in Chen, Y. and Hei an, M. L., Regulatory Peptide, 92: 113-119 (2000). The EE during the light photoperiod is indicative of the resting metabolic rate and RQ is indicative of the fuel source used by the animal (the pure carbohydrate metabolism gives an RQ of around 1.0, the pure fat metabolism gives an RQ of around 0.7 the metabolism of fat and mixed carbohydrates gives intermediate values for RQ). Calculate EE as the product of calorific value (CV) and V02 per body weight (kg); where CV = 3.815 + 1.232 * RQ, and RQ is the ratio of C02 produced (VC02) to 02 consumed (V02). The caloric intake is calculated as (mass of food intake in 24 hours in grams) x (value of the physiological fuel of the diet in kilocalories / g) per kg of body weight. Acute Feeding Test with a Selective 5-HT2C Receptor Antagonist: The previous acute calorimetric feeding assay is performed with the following modifications. Open circuit calorimetry systems are not used and only the periodic food intake is measured in 24 hours if the body weight. Three groups of rats are used with the first group receiving a subcutaneous dose of saline (0.5 mL) about 15 minutes prior to the oral dose of vehicle the second group receives a subcutaneous dose of saline (0.5mL) about 15 minutes prior to the oral dose of the test compound in the vehicle and the third group receives a subcutaneous injection of a selective receptor antagonist 5-HT2C, 6-chloro-5-methyl-N-. { 2- [(2-methylpyridin-3-yl-oxy) pyridin-5-yl] aminocarbonyl} -2, 3-dihydroindole (3 mg / Kg, in 35% cyclodextrin, 0.5 mL) about 15 minutes prior to the oral dose of the test compound in the vehicle. Chronic Feeding Trial: Between approximately 8:00 am and 10:00 am on day 1 of the trial, each rat is weighed and orally dosed with vehicle or test compound and the animal is returned to its home cage with free access to the food (pre-weighed) and water. For each of the days 2-15, between approximately 8:00 h and 10:00 h, the body weight of the rat and the weight of the food consumed in the last 24-hour period are measured and the oral dose of the test compound or vehicle is administered daily. On days 2 and 15 the total fat mass and the non-fat mass or nuclear magnetic resonance (NMR) are measured using a system at EchoMRI ™ (Echo Medical Systems, Houston Texas). See Frank C. Tinsley, Gersh Z. Taicher, and Mark L. Heiman, "Evaluation of a New Quantitative Magnetic Resonance (QMR) Method for Mouse Whole Body Composition Analysis", Evaluation of a New Quantitative Magnetic Resonance (QMR), Obesity Research, remitted on May 1, 2003). Representative compounds of the present invention are tested in acute and chronic feeding feeding assays essentially as described above. In acute trials, the compounds are found to significantly reduce food intake in 24 hours, whose effect is blocked by pre-administration of the 5-HT2c receptor antagonist. The compounds are also found to reduce the RQ dose dependent without significantly changing the energy expenditure during the light photoperiod. Thus, it is found that the compounds reduce caloric intake and increase the proportion of fuel derived from the use of fat, without significantly changing the metabolic rate at rest. In the chronic trial, the compounds are found to significantly decrease the cumulative dietary intake and the change in cumulative body weight in a dose-dependent manner compared to the control animals. The decrease in body weight is found to be due to the loss of adipose tissue while the non-fat body mass does not change. The ability of the 5-HT2c receptor agonists of the present invention to treat an obsessive / compulsive disorder is demonstrated by testing in a variety of in vivo assays as follows: Test of Canis Osultas (Marble Burying) The marbles hidden in mice have been used to model anxiety disorders that include obsessive compulsive disorders (OCD) due to the ethological study of behavior (for example, Gyertyan I. "Analysis of the marble burying response: Marbles serve to measure digging rather than evoke burying "(Analysis of the hiding response of marbles: Marbles are used to measure the excavation instead of causing concealment), Behavioral Pharmacology 6: 24-31, (1995)), and due to the pharmacological effects of clinical standards (cf, Njung'E K. Handley SL. "Evaluation of marble-burying behavior as a model of anxiety" (Evaluation of marbling concealment behavior as a model of anxiety), Pharmacology, Biochemistry &Behavior 38: 63-67, (1991)); Borsini F., Podhorna J., and Marazziti, D. "Do animal models of anxiety predict anxiolytic effects of antidepressants?" (Do animal models of anxiety predict the anxiolytic effects of antidepressants?) Psychopharmacology 163: 121-141, (2002)). Thus, drugs used in the treatment of generalized anxiety in humans (for example benzodiazepines) as well as the compounds used to treat OCD (for example, SSRIs such as fluoxetine) reduce concealment. NIH Swiss mice experimentally new laboratory mice (Harían Sprague-Dawley, Indianapolis, IN) weighing between 28-35 g in groups of 12, for at least three days prior to the test in a vivarium with 12 cycles of light and darkness. Experiments were performed during the light cycle in an experimental test room with dim light. The mice were dosed with vehicle or the test compound and after a specific pretreatment interval (generally 30 min), each mouse is individually placed in a rotorod (Ugo Basile 7650) operating at a speed of 6 revolutions per minute and watch the fall. After 2 minutes in the rotorod, the mice are placed individually in a high plastic tub of 17 x 28 x 12 cm with sawdust 5 mm on the floor that is covered with 20 blue marbles (1.5 cm diameter) placed in the middle. After 30 minutes, count the number of hidden marbles (covered in 2/3 with sawdust). The effect of the test compound on the hidden marbles is evaluated with Dunnett's test and the effect on rotorod performance by Fisher's exact test. The clinically effective standard compounds suppress the concealment of marbles at doses that are devoid of motor debilitating effects when measured in the rotor. The in vivo efficacy of the 5HT2C compounds at the 5HT2C receptor is confirmed by the prevention of effects of 5HT2c agonists in the occultation of marbles by the co-administration of the 5HT2C 6-chloro-5-methyl-N- receptor antagonist. { 2- [(2-methylpyridin-3-yl-oxy) pyridin-5-yl] aminocarbonyl} -2, 3-dihydroindole. The representative compounds of the present invention are tested in the marbling concealment assay essentially as described and surprisingly found to reduce the hiding behavior in the test mice. The reduction of the behavior to hide is found to be blocked by the co-administration of the 5HT2C antagonist. In contrast to the compounds of the present invention, the anxiolytic compound chlordiazepoxide and the antipsychotic compound chlorpromazine decrease the hiding of marbles only at doses that also alter the performance of the rotorod.
Shredded Nest (Nestlet Shredding) Mice will naturally build nests of available material in their living environment. Since this behavior is obsessive by nature, the OCD model has been used (Xia Li, Denise Morrow and Jeffrey M. Witkin, "Decreases in nestlet shredding of mice by serotonin uptake inhibitors: comparison with marble burying" of mice by serotonin uptake inhibitors: comparison with hiding marbles), Psychopharmacology, remitted on July 14, 2003). NIH Swiss mice experimentally laboratory new males (Harían Sprague-Dawley, Indianapolis, IN) weighing between 28-35 in groups of 12 for at least three days prior to testing in a vivarium with a 12-hour light / dark shekel . Experiments are carried out during the light cycle in an experimental room with fluorescent lighting in the upper normal part. The mice are dosed with vehicle or test compound and after a specific pre-treatment interval (generally 30 min.), The mice are placed individually in a high plastic tub of 17 x 28 x 12 cm with around fragments of 5 mm sawdust on the floor together with a pre-weighed multi-layer gauze pad (51 mm square). After 30 minutes, the weight of the remainder of the gauze pad is not removed by the mouse. The weight of the gauze used for the construction of the nest by subtraction is determined. The results for the mice treated with test compounds are compared with the results for the mice treated with the vehicle control with the Dunnett test. Standard compounds for the treatment of clinically effective OCD suppress trituration of the nest at doses that are devoid of motor debilitating effects when measured by the rotorod test. The in vivo efficacy of the 5HT2C compounds at the 5HT2C receptor is confirmed by the prevention of the effects of 5HT2C agonists in triturating the nest by the co-administration of the 5HT2C 6-chloro-5-methyl-N- receptor antagonist. { 2- [(2-methylpyridin-3-yl-oxy) pyridin-5-yl] aminocarbonyl} -2, 3-dihydroindole. The representative compounds of the present invention are tested essentially as described above and it is surprisingly found that they suppress trituration of the nest at doses that are devoid of motor debilitating effects when measured by the rotorod test. In contrast to the compounds of the present invention, the anxiolytic chlordiazepoxide and the psychomotor stimulant of d-amphetamine decrease the crushing of the nest only at doses that produce motor side effects (depression or stimulation, respectively).
Polydipsia Induced by Calendar Rats devoid of food exposed to intermittent feed presentations will drink quantities of water that are well in excess of their intake and normal area and in excess of their intake when they are given all their food at once (Falk JL. " Production of polydipsia in normal rats by an intermittent food schedule "(Production of polydipsia in normal rats through an intermittent feeding program), Science 133: 195-196, (1961)). This excessive behavior is persistent and has been used to model the OCD. Wistar rats are maintained on a restricted food diet (to maintain 85% free-feed weight) but with free access to water. The rats are trained in a behavioral test chamber to press a lever to receive a granule of feed under a schedule of fixed intervals so that the rats are rewarded with a 45 mg feed pellet the first time they press in. a lever after an interval of 120 seconds has elapsed. Then the fixed interval is restored to 120 seconds and the process is repeated. Thus during a 90-minute test session, rats can earn a maximum of 45 pellets. The behavior chamber is also occupied with a water bottle that is weighed before and after the session to determine the amount of water consumed. Test compounds are administered on Tuesdays and Fridays. The control day performances are determined on Thursdays. Compounds are administered either orally at 60 minutes before the start of a test session or subcutaneously at 20 minutes before the start of a testing session. The proportions of the lever that presses and the water consumption are compared for each performance of the animal during the sessions after the treatment with the test compound with that performance of the animal during the control sessions expressed as a percentage of the control relationship. The individual percentage of control ratios is averaged for each dose and the standard error of the mean is calculated. The standard compounds for treatment of clinically effective OCD (eg, clomipramine, fluoxetine) suppress calendar-induced polydipsia without producing noticeable changes in motor patterns, food intake or behavior the next day. The in vivo efficacy of the 5HT2c compounds at the 5HT2c receptor is confirmed by the prevention of the effects of 5HT2c agonists with excessive drinking by the co-administration of the 5HT2c receptor antagonist, 6-chloro-5-methyl-N-. { 2- [(2-methylpyridin-3-yl-oxy) pyridin-5-yl] aminocarbonyl} -2, 3-dihydroindole. Representative compounds of the present invention are tested in a calendar-induced polydipsia assay essentially as described above and surprisingly found to suppress calendar-induced polydipsia without producing noticeable changes in motor patterns, food intake and daily behavior. following. The suppression of behavior is blocked by the co-administration of the 5HT2c antagonist. In contrast to the compounds of the present invention, the psychomotor stimulant of d-amphetamine decreases excessive drinking only at doses that stimulate behavior and these effects are not avoided by the 5HT2c receptor antagonist. Although it is possible to administer the compounds employed in the methods of this invention directly without any formulation, the compounds are usually administered in the form of pharmaceutical compositions comprising a pharmaceutically acceptable excipient and at least one compound of formula I or a pharmaceutically acceptable salt thereof. These compositions can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular and intranasal. The compounds employed in the methods of this invention are effective both as injectable and oral compositions. Such compositions are prepared in a well-known form in the pharmaceutical art see for example, REMINGTON'S PHARMACEUTICAL SCIENCES (Pharmaceutical Sciences, Remington, (16th ed 1980) In the elaboration of the compositions employed in the present invention, the active ingredient is usually mixed with at least one excipient diluted by at least one excipient or enclosed within such a carrier which may be in the form of a capsule, sachet, paper, or other container.When the excipient serves as a diluent it may be a solid, semi-solid or liquid material which acts as a carrier vehicle or medium for the active ingredient. Thus, the compositions may be in the form of tablets, pills, powders, dragees, sachets, capsules, amylaceous capsules, elixirs, suspensions, emulsions, solutions, syrups, aerosols, (as a solid medium or in a liquid medium), ointments containing for example up to 10% by weight of the active compound, hard and soft gelatin capsules, suppositories, sterile injectable solutions, and packaged powders is In the preparation of a formulation, it may be necessary to grind the compound to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it is ordinarily milled to a particle size of less than 200 mesh. If the active compound is substantially soluble in water, the particle size is usually adjusted by grinding to provide a substantially uniform distribution in the formulation for example around 40 mesh. Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, acacia gum, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water , syrup, and methyl cellulose. The formulations may additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents, preservatives such as methyl and propylhydroxybenzoates; sweetening agents and flavoring agents. The compositions of the invention can be formulated so as to provide a sustained or delayed rapid release of the active ingredient after administration to the patient by employing procedures known in the art. The compositions are preferably formulated in a unit dosage form each dose contains from about 0.05 about 100 mg, more usually about 1.0 to about 30 mg, of the active ingredient. The term "unit dose form" refers to physically discrete units suitable as unit doses 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 excipient. The compounds are generally effective over a wide dose range. For example, doses per day formally fall within the range of about 0.01 around 30 mg / kg. In the treatment of adult humans the range of about 0.1 around 15 mg / kg / day in single or divided doses is especially preferred. However, it will be understood that the amount of the compound actually administered will be determined by a physician in light of the relevant circumstance, including the condition to be treated the chosen route of administration of the compound, current compounds administered the age, weight and response of the individual patient and the severity of the patient's symptoms and therefore the above dosage ranges are not intended to limit the scope of the invention in any way. In some cases, dose levels below the lower limit of the previous range may be more than adequate while in other cases still higher doses may be employed. Another preferred formulation employed in the methods of the present invention employs transdermal delivery device ("patches"). Such transdermal patches can be used to provide a continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art see for example U.S. Patents 5,023,252, issued June 11, 1991, which is incorporated herein by reference. Such patches can be constructed for continuous delivery, pulsing or delivery at the request of pharmaceutical agents. Under some circumstances, it will be desirable or necessary to introduce the pharmaceutical composition to the brain either directly or indirectly. Direct techniques usually involve the placement of a catheter for delivery of the drug into the host's ventricular system to bypass the blood barrier to the brain. One such implantable delivery system used for the transport of biological factors to specific anatomical regions of the body is described in U.S. Patent 5,011,472 issued April 30, 1991, which is incorporated herein by reference. Indirect techniques, which are generally preferred, usually involve formulating the compositions to provide drug latency by the conversion of hydrophilic drugs into lipid-soluble drugs or pro-drugs. Latency is generally achieved by blocking the primary amine, hydroxy, carbonyl and sulfate groups present in the drug to make the drug more soluble in lipids and akin to transport through the blood barrier to the brain. Alternatively, the supply of hydrophilic drugs can be enhanced by the intra-arterial infusion of hypertonic solutions which can transiently open the blood barrier to the brain. The type of formulation used for the administration of the compounds used in the methods of the present invention may be dictated by the compound employed in particular, the type of pharmacokinetic profile desired from the route of administration and the condition of the patient.
