FIELD OF THE INVENTION
The present invention relates to aryl- and heteroaryl-fused decahydropyrroloazepine, octahydrooxepinopyrrole, octahydropyrrolothiazepine dioxide, decahydrocyclohepta[c]pyrrole, and octahydrocyclohepta[c]pyrrole derivatives, methods of modulating the 5-HT2C receptor, the 5-HT6 receptor or both the 5-HT2C and 5-HT6 receptor in the prevention or treatment of serotonin-related conditions and disorders using such compounds or compositions containing such compounds, and processes for preparing such compounds and compositions.
BACKGROUND OF THE INVENTION
The present invention relates to compounds and pharmaceutical compositions containing the compounds useful as 5-HT2C receptor agonists or partial agonists, 5-HT6 antagonists or both 5-HT2C receptor agonists or partial agonists and 5-HT6 antagonists for the treatment of diseases, disorders and conditions where 5-HT2C or 5-HT6 modulation is desired such as depression, anxiety, schizophrenia, bipolar disorder, obsessive compulsive disorder, migraine, pain, epilepsy, substance abuse, eating disorders, obesity, diabetes, erectile dysfunction and others.
Serotonin (5-hydroxytryptamine, 5-HT), a monoamine neurotransmitter and local hormone, is formed by the hydroxylation and decarboxylation of tryptophan. The greatest concentration is found in the enterochromaffin cells of the gastrointestinal tract, the remainder being predominantly present in platelets and in the Central Nervous System (CNS). 5-HT is implicated in a vast array of physiological and pathophysiological pathways. In the periphery, it contracts a number of smooth muscles and induces endothelium-dependent vasodilation. In the CNS, it is believed to be involved in a wide range of functions, including the control of appetite, mood, anxiety, hallucinations, sleep, vomiting and pain perception.
Neurons that secrete 5-HT are termed serotonergic. The function of 5-HT is exerted upon its interaction with specific (serotonergic) neurons. Seven types of 5-HT receptors have been identified: 5-HT1 (with subtypes 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E and 5-HT1F), 5-HT2 (with subtypes 5-HT2A, 5-HT2B and 5-HT2C), 5-HT3, 5-HT4, 5-HT5 (with subtypes 5-HT5A and 5-HT5B), 5-HT6 and 5-HT5. Most of these receptors are coupled to G-proteins that affect the activities of adenylate cyclase or phospholipase Cγ.
Alterations in the activity of multiple neurotransmitter receptor systems (dopamine, serotonin, glutamate, GABA, acetylcholine) have been implicated in the manifestation of the symptoms of schizophrenia. The most widely accepted “Dopamine Hypothesis of Schizophrenia” in its simplest form states that the positive symptoms of this pathology relate to a functional hyperactivity of the mesolimbic dopaminergic system, while the negative and cognitive aspects can be traced to a functional hypoactivity of the mesocortical dopaminergic projections. Atypical antipsychotics block the mesolimbic dopaminergic neurotransmission, thereby controlling positive symptoms, with little or no effect on the nigrostriatal system, leading to less induction of extrapyramidal side effects (EPS).
Primary negative and cognitive symptoms of schizophrenia reflect a dysfunction of the frontal cortex (“hypofrontality”), which is thought to be induced by a decreased tone in the mesocortical dopaminergic projection field [Davis K L, Kahn R S, Ko G and Davidson M (1991). Dopamine in schizophrenia: a review and re-conceptualization. Am J Psychiatry 148: 1474-86. Weinberger D R and Berman K F (1996). Prefrontal function in schizophrenia: confounds and controversies. Philos Trans R Soc Lond B Biol Sci 351: 1495-503]. Agents that selectively enhance dopamine levels in the cortex have the potential to address the negative symptoms of this disorder. Atypical antipsychotics lack robust efficacy against negative and cognitive components of the schizophrenic syndrome.
The schizophrenic symptomotology is further complicated by the occurrence of drug-induced so-called secondary negative symptoms and cognitive impairment, which are difficult to distinguish from primary negative and cognitive symptoms [Remington G and Kapur S (2000). Atypical antipsychotics: are some more atypical than others? Psychopharmacol 148: 3-15]. The occurrence of secondary negative symptoms not only limits therapeutic efficacy but also, together with these side effects, negatively affects patient compliance.
It may thus be hypothesized that a novel mechanistic approach that blocks dopaminergic neurotransmission in the limbic system but does not affect the striatal and pituitary projection fields, and stimulates frontocortical projection fields, would provide an efficacious treatment for all parts of the schizophrenic pathology, including its positive, negative and cognitive symptoms. Moreover, a selective compound that is substantially free of the ancillary pharmacology that characterizes current agents would be expected to avoid a variety of off-target side effects that plague current treatments such as extrapyramidal side effects (EPS) and weight gain.
The 5-HT2C receptor, previously named 5-HT1C, is a G-protein-coupled receptor, which couples to multiple cellular effector systems including the phospholipase C, A and D pathways. It is found primarily in the brain and its distribution is particularly high in the plexus choroideus, where it is assumed to control cerebrospinal fluid production [Kaufman M J, Hirata F (1996) Cyclic GMP inhibits phosphoinositide turnover in choroid plexus: evidence for interactions between second messengers concurrently triggered by 5-HT2C receptors. Neurosci Lett 206:153-156]. Very high levels were also found in the retrosplenial, piriform and entorhinal cortex, anterior olfactory nucleus, lateral septal nucleus, subthalamic nucleus, amygdala, subiculum and ventral part of CA3, lateral habenula, substantia nigra pars compacta, several brainstem nuclei and the whole grey matter of the spinal cord [Pompeiano M, Palacios J M, Mengod G (1994). Distribution of the serotonin 5-HT2 receptor family mRNAs: comparison between 5-HT2A and 5-HT2C receptors. Brain Res Mol Brain Res 23:163-178]. A comparison of the distribution of 5-HT2C mRNA with that of 5-HT2C protein in monkey and human brains has revealed both pre- and postsynaptic localization [Lopez-Gimenez J F, Mengod G, Palacios J M, Vilaro M T (2001) Regional distribution and cellular localization of 5-HT2C receptor mRNA in monkey brain: comparison with [3H]mesulergine binding sites and choline acetyltransferase mRNA. Synapse 42:12-26].
It is anticipated that modulation of the 5-HT2C receptor will improve disorders such as depression, anxiety, schizophrenia, cognitive deficits of schizophrenia, obsessive compulsive disorder, bipolar disorder, migraine, epilepsy, substance abuse, eating disorders, obesity, diabetes, sexual dysfunction/erectile dysfunction, sleep disorders, psoriasis, Parkinson's disease, pain conditions and disorders, and spinal cord injury, smoking cessation, ocular hypertension and Alzheimer's disease. Modulators of the 5-HT2C receptor are also shown to be useful in the modulation of bladder function, including the prevention or treatment of urinary incontinence.
The modulation of the 5-HT6 receptor by suitable substances is expected to improve certain disorders including cognitive dysfunctions, such as a deficit in memory, cognition and learning associated with Alzheimer's disease, age-related cognitive decline and mild cognitive impairment, attention deficit disorder/hyperactivity syndrome, personality disorders, such as schizophrenia, in particular cognitive deficits related with schizophrenia, affective disorders such as depression, anxiety and obsessive compulsive disorders, motion or motor disorders such as Parkinson's disease and epilepsy, migraine, sleep disorders (including disturbances of the Circadian rhythm), feeding disorders, such as anorexia and bulimia, certain gastrointestinal disorders such as Irritable Bowel Syndrome, diseases associated with neurodegeneration, such as stroke, spinal or head trauma and head injuries, such as hydrocephalus, drug addiction and obesity.
There is still an ongoing need for providing compounds having high affinity and selectivity for the 5-HT6 receptor. In particular the compounds should have low affinity to adrenergic receptors, such as the α1-adrenergic receptor, histamine receptors, such as the H1-receptor, and dopaminergic receptors, such as the D2-receptor, in order to avoid or reduce side effects associated with modulation of these receptors, such as postural hypotension, reflex tachycardia, potentiation of the antihypertensive effect of prazosin, terazosin, doxazosin and labetalol or dizziness associated with the blockade of the α1-adrenergic receptor, weight gain, sedation, drowsiness or potentiation of central depressant drugs associated with the blockade of the H1-receptor, or extrapyramidal movement disorder, such as dystonia, parkinsonism, akathisia, tardive dyskinesia or rabbit syndrome, or endocrine effects, such as prolactin elevation (galactorrhea, gynecomastia, menstrual changes, sexual dysfunction in males), associated with the blockade of the D2-receptor.
The present invention provides compounds which have an affinity for the 5-HT2C or 5-HT6 receptor or both the 5-HT2C and 5-HT6 receptors, thus allowing the treatment of disorders related to or affected by the 5-HT2C or 5-HT6 receptors or both the 5-HT2C and 5-HT6 receptors.

Stereoisomers include enantiomers and diastereomers, and mixtures of enantiomers or diastereomers. Individual stereoisomers of compounds of the invention may be prepared synthetically from commercially available starting materials which contain asymmetric or chiral centers or by preparation of racemic mixtures followed by resolution well-known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and optional liberation of the optically pure product from the auxiliary as described in Furniss, Hannaford, Smith, and Tatchell, “Vogel's Textbook of Practical Organic Chemistry”, 5th edition (1989), Longman Scientific & Technical, Essex CM20 2JE, England, or (2) direct separation of the mixture of optical enantiomers on chiral chromatographic columns or (3) fractional recrystallization methods.
In another embodiment of this invention, therefore, pertains to a process for making (3aS,10bS)-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one comprising:
(a) combining dibenzoyl-D-tartaric acid (1.05 equivalents) and methanol;
(b) adding a solution of trans-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one (0.10-0.15 equivalents) in methanol;
(c) seeding the solution with (3aS,10bS)-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one which are obtained in smaller batches of the same sequence iteratively increasing the enantiomeric excess in successive passage;
(d) slowly adding additional trans-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one (0.85-0.90 equivalents) dissolved in methanol; and
(e) stirring the resultant mixture for a period of time resulting in crystallization and isolating the crystalline (3aS,10bS)-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one dibenzyoyl-D-tartrate.
Another embodiment of this invention pertains to a process for making (3aS,10bS)-8-hydroxy-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one comprising:
(a) combining palladium(II) acetate (0.04 equivalents), 2-di-tert-butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropyl-1,1′-biphenyl (0.05 equivalents), cesium carbonate (1.5 equivalents) and (3aS,10bS)-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one (1 equivalent);
(b) adding a solution of benzyl alcohol (20 equivalents) in toluene to the mixture of palladium(II) acetate, 2-di-tert-butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropyl-1,1′-biphenyl, cesium carbonate and (3aS,10bS)-8-chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one;
(c) isolating the (3aS,10bS)-8-(benzyloxy)-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one;
(d) combining (3aS,10bS)-8-(benzyloxy)-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one with catalyst JM UK#3 (10 weight percent dry basis, catalyst in 50>9% water) and methanol and hydrogenating the mixture for 5 minutes to 24 hours; and
(e) isolating the (3aS,10bS)-8-hydroxy-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one.
The present application contemplates various stereoisomers and mixtures thereof and these are specifically included within the scope of this application. Stereoisomers include enantiomers and diastereomers, and mixtures of enantiomers or diastereomers. Individual stereoisomers of compounds of the present application may be prepared synthetically from commercially available starting materials which contain asymmetric or chiral centers or by preparation of racemic mixtures followed by resolution which is well known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and liberation of the optically pure product from the auxiliary or (2) direct separation of the mixture of optical enantiomers on chiral chromatographic columns.
Geometric isomers may exist in the compounds of the present invention. The present invention contemplates the various geometric isomers and mixtures thereof resulting from the disposition of substituents around a carbon-carbon double bond, a carbon-nitrogen double bond, a cycloalkyl group, or a heterocycle group. Substituents around a carbon-carbon double bond or a carbon-nitrogen bond are designated as being of Z or E configuration and substituents around a cycloalkyl or a heterocycle are designated as being of cis or trans configuration.
Within the present invention it is to be understood that compounds disclosed herein may exhibit the phenomenon of tautomerism.
Thus, the formulae drawings within this specification can represent only one of the possible tautomeric or stereoisomeric forms. It is to be understood that the present invention encompasses any tautomeric or stereoisomeric form, and mixtures thereof, and is not to be limited merely to any one tautomeric or stereoisomeric form utilized within the naming of the compounds or formulae drawings.
The present invention also includes isotopically-labeled compounds, which are identical to those recited in Formula I, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds of the invention are hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, and chlorine, such as, but not limited to 2H, 3H, 13C, 14C, 15N, 18O, 17O, 31P, 32P, 35S, 18F, and 36Cl, respectively. Substitution with heavier isotopes such as deuterium, i.e., 2H, can afford certain therapeutic advantages resulting from greater metabolic stability, for Example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Compounds incorporating positron-emitting isotopes are useful in medical imaging and positron-emitting tomography (PET) studies for determining the distribution of receptors. Suitable positron-emitting isotopes that can be incorporated in compounds of formula (I) are 11C, 13N, 15O, and 18F. Isotopically-labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples using appropriate isotopically-labeled reagent in place of non-isotopically-labeled reagent.
c. Biological Data
To determine the effectiveness of compounds having a formula (I), these compounds can be evaluated in a radioligand binding assay for the agonist site of the human serotonin 5-HT2C receptor, the human 5-HT6 receptor or in vitro models of cellular function.

(i) Human 5-HT2C Receptor Radioligand Binding Assay
Affinity of compounds for the agonist site of the 5-HT2C receptor in transfected CHO cells was determined in a radioligand binding assay essentially as described by Bryant, H. U., et al., Life Sciences (1996) 59(15), 1259-1268. In brief, cell membrane homogenates with 40 μg of protein were incubated for 15 minutes at 37° C. with 0.2 nM [125I](±)(1-(4-iodo-2,5-dimethoxyphenyl)isopropylamine (DOI) with or without test compounds in a buffer containing 50 mM Tris-HCl, 5 mM MgCl2 and 0.3% BSA. Nonspecific binding was determined in the presence of 10 μM (±)DOI. The amount of binding was determined by radioactivity quantitation with scintillation counter. IC50s were determined from a standard curve of the reference compound (±)DOI. Ki's as shown in Table 1 were derived from the IC50s in the standard method.

(ii) Human 5-HT2C Functional Assay in 1321N1 Cells
Functional activity was determined by testing the effect of the compounds on intracellular calcium levels in 1321N1 cells stably transfected with the human 5-HT2C receptor. Cells were seeded into 96-well plates at 50,000 cells/well and grown overnight in tissue culture medium (DMEM with Glutamax I (Invitrogen), containing 10% dFCS, 50 μg/mL Gentamicin, 400 μg/mL Geneticin) at 37° C. and 7% CO2. Growth medium was replaced by medium without dFCS for overnight incubation. Cells were loaded with a fluorescent calcium-sensitive dye in the presence of 1% probenicid according to the manufacturer's protocol (Fluo4 AM, Molecular Devices). Serial compound dilutions (final concentrations 10−10 to 10−5 M) were added to the cells either alone or in the presence of serotonin (10−9 M) and the maximum calcium response was determined using a FLIPR instrument (Molecular Devices). Concentration-response curves were fitted using a four-parameter logistic equation (GraphPad Prism). The concentration at which the compound exerts half its maximal effect is named the ‘effective concentration 50’ or ‘EC50’ and is listed in Table 2.

(iii) Human 5-HT2C and 5-HT2B Functional High Throughput Screening Assays in CHO-K1 Cells
CHO-K1 cells over-expressing 5HT2C or 5HT2B receptors were grown in 1272 cm2 flasks to 70-80% confluency in UltraCHO media (Lonza, Walkersville, Md.) supplemented with 1% dialyzed fetal bovine serum (FBS), 250 μg/mL zeocin, 100 U/mL penicillin and 100 μg/mL streptomycin, and 400 μg/mL geneticin. The cells were dissociated from the flasks using 0.05% trypsin, resuspended in RecoveryTM cell culture freezing medium (Invitrogen, Carlsbad, Calif.) and stored in liquid nitrogen until use. The calcium flux experiments were done using frozen cells. The cells were diluted in media containing 1% dialyzed FBS and 100 U/mL penicillin and 100 μg/mL streptomycin and plated into 384-well poly-D-Lysine coated plates (15,000 cells/well). Then the plates were incubated overnight in a cell incubator at 37° C., 5% CO2. On the next day, the growth media was replaced with media without FBS and further incubated overnight. On day three, the changes in intracellular Ca2+ were determined using calcium sensitive fluorescent dye, Ca4 (MDS Analytical Technologies, Sunnyvale, Calif.) by loading 15 μL of diluted dye in Hank's Balanced Salt Solution and 20 mM Hepes buffer (pH 7.4) with final concentration of 2.5 mM probenecid into the cells containing media. Then the cells were incubated at room temperature for 60 minutes in dark.
After incubation, the cell plates were transferred to FLIPRTM (MDS) and their fluorescence measurements were read at an excitation wavelength of 480 nm and an emission wavelength of 530 nm at 25° C. The baseline fluorescence was measured for the first 10 seconds and then 15 μL of 4× concentration of serotonin/test compound was added to the cells. The fluorescence intensity was captured every second for the first 1 minute followed by every 5 seconds for an additional 2 minutes. The increase in fluorescent response by a test compound was normalized to the response of serotonin and used to determine agonist activity. The concentration response of compounds was done from a starting concentration of 10 μM, 1:10 dilution across 6 wells with a final dimethyl sulfoxide concentration of 0.2% and was fitted using a 4-parameter logistic equation. The concentration at which a compound exerts half its maximal effect was named as ‘effective concentration 50’ or ‘EC50’. Emax is the maximum functional response or efficacy expressed as a percentage relative to the effect of serotonin.

(iv) Human 5-HT2C Functional Assay in CHO-K1 Cells
Functional activity was determined by testing the effect of the compounds on intracellular calcium levels in CHO-K1 cells stably transfected with the human 5-HT2C receptor. Cells were seeded into 96-well plates at 60,000 cells/well and grown overnight in tissue culture medium (UltraCHOTM (Lonza), containing 1% dFCS, 250 μg/mL Zeocin, 400 μg/mL Geneticin) at 37° C. and 5% CO2. Growth medium was replaced by medium without dFCS for overnight incubation. Cells were loaded with a fluorescent calcium-sensitive dye in the presence of probenicid according to the manufacturer's protocol (FLIPR Ca4 Assay kit, Molecular Devices). Serial compound dilutions (final concentrations 10−10 to 10−5 M) were added to the cells and the maximum calcium response was determined using a FLIPR instrument (Molecular Devices). Concentration-response curves were fitted using a four-parameter logistic equation (GraphPad Prism). The concentration at which the compound exerts half its maximal effect is named the ‘effective concentration 50’ or ‘EC50’ and is listed in Table 5.

(v) Human 5-HT6 Receptor Radioligand Binding Assay
Preparation of Membranes by Ultrasonic Treatment and Differential Centrifugation
Cells from stable clonal cell lines expressing the corresponding receptor (5-HT6) were washed with PBS (without Ca++, Mg++) and harvested in PBS with 0.02% EDTA. The cells were collected by centrifugation at 500 g for 10 minutes at 4° C., washed with PBS and centrifuged (500 g, 10 minutes at 4° C.). The pellets were stored at −80° C. until use. For membrane preparation, the thawed cell pellet was resuspended in ice-cold sucrose buffer (0.25 M sucrose, 10 mM HEPES (pH 7.4), 1 mM phenylmethylsulfonyl fluoride (PMSF) in DMSO, 5 μg/ml Pepstatin-A, 3 mM EDTA, 0.025% Bacitracin) and homogenized with a Branson Sonifier W-250 (Settings: Timer 4; Output Control 3; Duty Cycle constant; 2 to 3 cycles). Cell disruption was checked with the aid of a microscope. Remaining unbroken cells were pelleted at 1,000 g for 10 minutes at 4° C. The sucrose buffer supernatant was then centrifuged at 60,000 g for 1 hour at 4° C. (Beckman Ultracentrifuge XL 80). The pellet was resuspended in 30 mL of ice-cold Tris buffer (20 mM TRIS (pH 7.4), 5 μg/mL Pepstatin A, 0.1 mM PMSF, 3 mM EDTA) by pipetting through a 10 mL serological pipet and centrifuged for 1 hour at 4° C. at 60,000 g. A final resuspension was performed in a small volume of ice-cold Tris buffer (see above) by pressing through a serological pipet followed by ultrasonic treatment with a Branson Sonifier W-250 (Settings: Timer 1; Output Control 3; Duty Cycle constant; 1 cycle). Protein concentration was determined (BCA-Kit; Pierce) and aliquots stored at −80° C. or in liquid nitrogen for long-term storage.
Receptor Binding Experiments
All receptor binding experiments were carried out in the corresponding assay buffer in a total volume of 200 μL in the presence of various concentrations of test compound (10−5 M to 10−9 M, tenfold serial dilution, duplicate determinations). The assays were terminated by filtration on polyethylenimine (PEI 0.1% or 0.3%) presoaked Packard Unifilter Plates (GF/C or GF/B) with a Tomtec MachIII U 96 well-plate harvester. After the plates had been dried for 2 hours at 55° C. in a drying chamber scintillation cocktail (BetaPlate Scint; PerkinElmer) was added. Radioactivity was measured in a Microbeta Trilux two hours after the addition of the scintillation mixture.
5-HT6 Receptor Binding Assay
HEK293 cells stably expressing the h-5-HT6 receptor (NCBI Reference Sequence XM 001435) were cultured in RPMI1640 medium supplemented with 25 mM HEPES, 10% fetal calf serum and 1-2 mM glutamine. The membrane preparation was performed as described above. For these membranes a KD of 1.95 nM for [3H]-LSD (Lysergic Acid Diethylamide; Amersham, TRK1038) was determined by means of saturation binding experiments. On the day of the assay, the membranes were thawed, diluted in assay buffer (50 mM Tris-HCl, 5 mM CaCl2, 0.1% ascorbic acid, 10 μM pargyline, pH 7.4) to a concentration of 8 μg protein/assay and homogenized by gentle vortexing. For inhibition studies, 1 nM [3H]-lysergic acid diethylamide was incubated in the presence of various concentrations of test compound in assay buffer. Non-specific binding was defined with 1 μM methiothepin. The binding reaction was carried out for 3.5 hours at room temperature. During the incubation, the plates were shaken on a plate shaker at 100 rpm and terminated by filtration on Packard Unifilter GF/C (0.1% PEI) plates, followed by 2 wash cycles with ice-cold 50 mM Tris-HCl, 5 mM CaCl2.
Data Analysis
Data derived from liquid scintillation counting were analyzed by iterative non-linear regression analysis with the use of the Statistical Analysis System (SAS): a program similar to “LIGAND” as described by Munson and Rodbard (Anal. Biochem. 1980, 107, 220-239). Fitting was performed according to formulae described by Feldman (Anal. Biochem. 1972, 48, 317-338). IC50 and Ki values were expressed as geometrical mean. For receptors with a low affinity for the test compound, where the highest tested compound concentration inhibited less than 30% of specific radioligand binding, Ki-values were determined according to the equation of Cheng and Prusoff (Biochem. Pharmacol. 1973, 22, 2099-2108) and expressed as greater than (>).
The results of the receptor binding studies are expressed as receptor binding constants Ki(5-HT6) as described herein before, and given in Table 6.

In these tests, the compounds according to the invention exhibit good affinity for the 5-HT6 receptor (Ki<1000 nM or <50 nM).
(vi) Human 5-HT6 Receptor Radioligand Binding Assay
Affinity of compounds for the agonist site of the 5-HT6 receptor in transfected CHO cells was determined in a radioligand binding assay essentially as described by Monsma, F. J., et al., Mol. Pharmacol. (1993) 43, 320-327. In brief, cell membrane homogenates were incubated for 120 minutes at 37° C. with 2 nM [3H]lysergic acid diethylamide (LSD) with or without test compounds. Nonspecific binding was determined in the presence of 100 μM serotonin. The amount of binding was determined by radioactivity quantitation with scintillation counter. IC50s were determined from a standard curve of the reference compound serotonin. Ki's as shown in Table 7 were derived from the IC50s in the standard method.

(vii) Assessment of Effects on Psychostimulant-Induced Hyperlocomotion in Rat
In humans, phencyclidine (PCP) is known to produce a syndrome of behavioral effects which have many characteristics in common with schizophrenia. Therefore, antagonism of PCP effects might be evidence for antipsychotic efficacy of a compound.
Methods
Male CD rats with a body weight of 316-394 g from Charles River (Portage, Mich.) were used in this study. The rats were habituated to the test room for 60 minutes. The rats were then placed into the locomotor activity chambers (AccuScan Instruments) for 30 minutes and then were dosed i.p. with Example 115 at 0, 1, 3 and 10 mg/kg. The rats were dosed sc 30 minutes later with PCP at 0 or 2 mg/kg. The activity was measured for 150 minutes in total and 90 minutes post PCP.
Results
As shown in FIG. 1, the PCP-treated group showed significant hyperlocomotion (p<0.01, vs. Veh-Veh group). Example 115 at 1 mg/kg and 10 mg/kg was able to significantly attenuate the PCP-induced hyperlocomotion.
(viii) Inhibitory Avoidance in Mouse
Glutamate has been shown to play a pivotal role in neuroplasticity, learning, memory, and neurodegenerative diseases. Specifically in the hippocampus CA1 area, N-methyl-D-aspartic acid (NMDA) receptors are known to regulate synaptic plasticity, long term-potentiation (LTP), and learning and memory processes, including short- and long-term memories. The non-competitive NMDA antagonist MK-801 has been shown to impair learning and memory processes in various tasks. The inhibitory avoidance task involves the uses of a two-compartment step through apparatus (Ugo Basile, Collegeville, Pa.) that measures the animal's ability to remember a brief noxious stimulus (foot shock), and is considered a measure of trial learning, and memory. (Bitner, R. S., et al. J. Neurosci. 2007, 27(39), 10578-10587). The purpose of this experiment was to test the ability of a 5HTc agonist to attenuate MK-801-induced deficits in the 24-hour inhibitory avoidance test. Effects against MK-801-induced cognitive impairment may indicate a potential efficacy in treating cognitive deficits of schizophrenia.
Methods:
Following a 2 hour habituation period, CD1 mice first received i.p. treatment with the test compound at 0, 1, 3, 10 mg/kg. 20 minutes later mice then received either MK-801 at 0.1 mg/kg (dissolved in 0.3% tartaric acid) or vehicle (Veh, water). 20 minutes after MK-801 administration, mice began their training session. For the training session, mice were placed into the light side of a 2-chambered compartment. The latency to enter the adjoining dark chamber was recorded, and an inescapable foot shock (0.3 mA, 1 second duration) was presented to the mouse. The mouse was removed from the chamber and returned to the home cage. Twenty-four hours later, the mouse was tested using methods identical to those on the training day, without being dosed or shocked. The latency to enter the dark chamber was recorded and was the dependent variable measured for assessing memory retention. If the mouse did not enter the dark chamber after 180 seconds, the test trial was terminated and the mouse was given a score of 180 seconds.
Results:
Acute administration of Example 115, at the high dose of 10 mg/kg, significantly increased transfer latencies compared to Veh-MK-801, indicating a procognitive effect (FIG. 2).
(ix) 5-Trial Inhibitory Avoidance/Impulsivity Model in the Pups of Spontaneously Hypertensive Rat
Spontaneously hypertensive rats (SHR) exhibit many behavioral features characteristic of attention-deficit hyperactivity disorder (ADHD), including hyperactivity, impaired response inhibition, impaired sustained attention and decreased cognitive function compared with age- and sex-matched controls from the same genetic background or from other rat strains. However, the adult rats have spontaneous hypertension which may confound behavioral assessment. The juvenile SHRs were used in the current study since these pups show similar behavioral deficits while having not developed hypertension. The aim was to investigate the efficacy of 5-HT2c agonists in SHR pups in an inhibitory avoidance model, as indication of enhancement of inhibitory control/or anti-impulsivity.
Methods:
SHR pups at postnatal day 21-28 were sc dosed with either vehicle or Example 115 (1, 3, and 10 mg/kg; dissolved in tartaric acid/PH4-6) 30 minutes prior to the test. Upon testing initiation, pups were placed into the light side of a computer controlling 2-chambered compartment. The latency to enter the adjoining dark chamber was recorded, and an inescapable footshock (0.1 mA, 1 second duration) was presented to the pup. The pup was removed, placed back into the home cage for approximately 1 minute, and the process repeated for a total of 5 trials. The dependent variable used for data analysis was the total transfer latency of trial 2 to trial 5.
Results:
The acute administration of Example 115 did result in a dose-dependent increase in transfer latencies across learning trials 2-5 at all three doses tested compared to vehicle (FIG. 3). The study demonstrated that Example 115 enhanced performance in the SHR pups in this 5-trial inhibitory avoidance/impulsivity model.

In both humans and experimental animals amphetamine (AMP) profoundly affects motor activity, sensorimotor function, sleep, attention, aggressive and sexual behaviors, learning and memory, operant behaviors, appetite and food intake. In addition, amphetamine induces psychotic reactions in normal individuals and exacerbates symptoms of schizophrenia in patients. In experimental animals several distinct behaviors are considered to be correlates of amphetamine psychosis. For Example, amphetamine-induced hyperactivity in rodents is believed to model the psychotic symptoms of schizophrenia. Reversal of these behaviors is used to predict potential antipsychotic activity of drugs in pre-clinical studies.
In humans, phencyclidine (PCP) is known to produce a syndrome of behavioral effects which have many characteristics in common with schizophrenia. Therefore, antagonism of PCP effects might be evidence for antipsychotic efficacy of a compound.
Animals
Male NMRI mice (5-week old, Janvier, France) or C57BL/6J mice (6-week old, Janvier, France) were group housed and allowed ad-libitum access to food and water. A 12 hour light/dark cycle was imposed with lights-on period between 0530 and 1730 hours. All testing occurred between 700 and 1300 hours. All procedures were approved by Abbott Institutional Animal Care and Use Committee (USA) or Animal Welfare Officer (Germany) and were conducted in accordance with the National Institutes of Health Guide for Care and Use of Laboratory Animals guidelines and applicable national laws in the facilities accredited by the Association for the Assessment and Accreditation of Laboratory Animal Care.
Methods
On the day of experiment, animals were brought from the animal facility into the experimental room and were allowed to acclimatize for at least 30 minutes. Animals were then placed in the test cages for a habituation period of 60 minutes. The animals were then injected ip with the test compound and returned to the test cage. 30 Minutes later the mice were injected with d-amphetamine (2.0 mg/kg, AMP, Sigma, #A5880, sc) or phencyclidine (2.0 mg/kg, PCP, Sigma, #P3029, sc) Sigma, and returned to the test cages for 90 minutes. Each treatment group consisted of 8-10 animals. The data was acquired by Cage rack Photobeam system (SDI, San Diego Instruments, CA). The analyzed data were: fine movements, ambulations and total movements (fine+ambulations). Data was subjected to one- or two-way distribution-free ANOVA followed by Dunnett's and Tukey's post hoc tests.
Results
Example 44 attenuated PCP-induced hyperactivity in mice significantly and in a dose dependent manner (treatment×time interaction F(3,26)=1.47, p<0.01), without affecting spontaneous activity (FIGS. 4A and 4B).
Example 106 modestly attenuated AMP-induced hyperactivity in mice in a dose dependent manner (time×treatment interaction F(3, 29)=1.48, p<0.01), without affecting spontaneous activity (FIGS. 5A and 5B).
Example 115 attenuated AMP-induced hyperactivity in mice significantly and in a dose dependent manner (treatment×time interaction F(3,29)=2.65, p<0.001), without affecting spontaneous activity (FIGS. 6A and 6B).
Example 158 attenuated AMP-induced hyperactivity in mice significantly and in a dose dependent manner (treatment×time interaction F(3,29)=9.51, p<0.0001) (FIGS. 7A and 7B).
Example 225 modestly attenuated AMP-induced hyperactivity in mice without affecting spontaneous activity (FIGS. 8A and 8B).
(xi) Assessment of Effects on Conditioning Avoidance Responding in Rats
Antipsychotics were found to have a unique ability to selectively suppress a conditioned avoidance response (CAR) behavior in rats. The fact that antipsychotics have the unique ability to selectively suppress CAR behavior, made the CAR test a useful tool for the screening of new, potentially antipsychotic compounds. All clinically effective antipsychotics (typical and atypical) have been shown to selectively suppress CAR.
Animals
Male Wistar rats (9-11 weeks old, Charles River, Germany) were pair-housed and allowed ad-libitum access to food and water. A 12-hour light/dark cycle was imposed with lights-on period between 0530 and 1730 hours. All testing occurred between 700 and 1300 hours. All procedures were approved by Abbott Institutional Animal Care and Use Committee (USA) or Animal Welfare Officer (Germany) and were conducted in accordance with the National Institutes of Health Guide for Care and Use of Laboratory Animals guidelines and applicable national laws in the facilities accredited by the Association for the Assessment and Accreditation of Laboratory Animal Care.
Methods
Wistar rats are exposed to a conditioned stimulus CS (a 2.9-kHz tone of 10 second duration), which is a signal for the animal that it must move into the other chamber in order to avoid an immediately ensuing footshock US (0.5 mA, 10 second, tone continues during shock presentation). Once the shock has begun, the animal can still escape it by moving to the other chamber. Each session is limited to a maximum of 40 trials (intertrial interval 10-90 seconds). The animals generally learn quickly to change chambers upon the conditioned stimulus and thus avoid further shocks. Scored are:

    
    
        Avoided responses=crossings into other compartment within 10 seconds of tone presentation;
        Escaped responses=crossings between 10-20 seconds of tone presentation;
        Failures=crossings after cessation of tone-shock presentation or no crossing.
    
    


Animals are trained for 2 weeks, one session per day, or until they achieve a stable avoidance performance for at least 3 days of 75% (=30 avoided trials out of 40). At the test sessions (=CS-shock pairings), animals are pre-treated with a test drug or vehicle 30 minutes before commencement of the session.
Results
Example 115 significantly suppressed conditioned avoidance behavior in rats (p<0.05) without affecting the number of failures, indicating that the effect observed is not due to sedation or extrapyramidal side effects (FIG. 9A avoided responses; FIG. 9B escaped responses; FIG. 9C failure responses).
Example 158 significantly suppressed conditioned avoidance behavior in rats (p<0.01) without affecting the number of failures, indicating that the effect observed is not due to sedation or extrapyramidal side effects (FIG. 10A avoided responses; FIG. 10B escaped responses; FIG. 10C failure responses).

There are several lines of evidence suggesting that 5-HT2C agonists or partial agonists would have therapeutic use in a variety of diseases, disorders and conditions.
Knockout mice models lacking the 5-HT2C receptor exhibit hyperphagia, obesity and are more prone to seizures and sudden death [Tecott L H, Sun L M, Akana S F, Strack A M, Lowenstein D H, Dallman M F, Julius D (1995) Eating disorder and epilepsy in mice lacking 5-HT2C serotonin receptors. Nature 374:542-546]. They also exhibit compulsive-like behavior [Chou-Green J M, Holscher T D, Dallman M F, Akana S F (2003). Compulsive behavior in the 5-HT2C receptor knockout mouse. Phys. Behav. 78:641-649], hyperresponsiveness to repeated stress [Chou-Green J M, Holscher T D, Dallman M F, Akana S F (2003). Repeated stress in young and old 5-HT2C receptor knockout mouse. Phys. Behav. 79:217-226], wakefulness [Frank M G, Stryker M P, Tecott L H (2002). Sleep and sleep homeostasis in mice lacking the 5-HT2C receptor. Neuropsychopharmacology 27:869-873], hyperactivity and drug dependence [Rocha B A, Goulding E H, O'Dell L E, Mead A N, Coufal N G, Parsons L H, Tecott L H (2002). Enhanced locomotor, reinforcing and neurochemical effects of cocaine in serotonin 5-hydroxytryptamine 2C receptor mutant mice. J. Neurosci. 22:10039-10045].
5-HT2C is unique among other G-protein-coupled receptors (GPCRs) in that its pre-mRNA is a substrate for base modification via hydrolytic deamination of adenosines to yield inosines. Five adenosines, located within a sequence encoding the putative second intracellular domain can be converted to inosines. This editing can alter the coding potential of the triplet codons and allows for the generation of multiple different receptor isoforms. The edited receptor isoforms were shown to have reduced ability to interact with G-proteins in the absence of agonist stimulation [Werry, T D, Loiacono R, Sexton P A, Christopoulos A (2008). RNA editing of the serotonin 5-HT2C receptor and its effects on cell signaling, pharmacology and brain function. Pharmac. Therap. 119:7-23].
Edited 5-HT2C isoforms with reduced function are significantly expressed in the brains of depressed suicide victims [Schmauss C (2003) Serotonin 2C receptors: suicide, serotonin, and runaway RNA editing. Neuroscientist 9:237-242. Iwamoto K, Kato T (2003). RNA editing of serotonin 2C receptor in human postmortem brains of major mental disorders. Neurosci. Lett. 346:169-172] and in the learned helplessness rats (a well established animal model of depression) [Iwamotoa K, Nakatanib N, Bundoa M, Yoshikawab T, Katoa T (2005). Altered RNA editing of serotonin 2C receptor in a rat model of depression. Neurosci. Res. 53: 69-76] suggesting a link between 5-HT2C function and depression. There are also implications of edited 5-HT2C isoforms and spatial memory [Du Y, Stasko M, Costa A C, Davissone M T, Gardiner K J (2007). Editing of the serotonin 2C receptor pre-mRNA Effects of the Morris Water Maze. Gene 391:186-197]. In addition, fully edited isoforms of the human 5-HT2C receptor display a striking reduction in sensitivity to lysergic acid diethylamide (LSD) and to atypical antipsychotic drugs clozapine and loxapine, suggesting a possible role of the receptor in the etiology and pharmacology of schizophrenia [Niswender C M, Herrick-Davis K, Dilley G E, Meltzer H Y, Overholser J C, Stockmeier C A, Emeson R B, Sanders-Bush E (2001). RNA Editing of the Human Serotonin 5-HT2C Receptor: Alterations in Suicide and Implications for Serotonergic Pharmacotherapy. Neuropsychopharm. 24:478-491].
Recently, the availability of potent and selective 5-HT2C receptor agonists made it possible to directly investigate the effects of 5-HT2C agonists and their therapeutic potential. Thus recent studies demonstrated that selective 5-HT2C agonists resulted in decreased food intake and body weight gain in normal and obese rats [Smith B M, et al. (2008).

J Pharmacol Exp Ther. 313:862-869.].
Furthermore, selective 5-HT2C receptor agonists produce antidepressant effects in animal models of depression comparable to those of SSRIs but with a much faster onset of action and a therapeutic window that avoids antidepressant-induced sexual dysfunction. These agonists were also effective in animal models of compulsive behavior such as scheduled induced polydipsia and they also exhibited decreased hyperactivity and aggression in rodents [Rosenzweig-Lipson S, Sabb A, Stack G, Mitchell P, Lucki I, Malberg J E, Grauer S, Brennan J, Cryan J F, Sukoff Rizzo S J, Dunlop J, Barrett J E, Marquis K L (2007) Antidepressant-like effects of the novel, selective, 5-HT2C receptor agonist WAY-163909 in rodents.

Acute or chronic administration of 5-HT2C agonists decreases the firing rate of ventral tegmental area dopamine neurons but not that of substantia nigra. In addition 5-HT2C agonists reduce dopamine levels in the nucleus accumbens but not in the striatum (the region of the brain mostly associated with extrapyramidal side effects) [Di Matteo, V., Di Giovanni, G., Di Mascio, M., & Esposito, E. (1999). SB 242084, a selective serotonin 2C receptor antagonist, increases dopaminergic transmission in the mesolimbic system. Neuropharmacology 38, 1195-1205.

Marquis K L, Sabb A L, Logue S F, Brennan J A, Piesla M J, Comery T A, Grauer S M, Ashby C R, Jr., Nguyen H Q, Dawson L A, Barrett J E, Stack G, Meltzer H Y, Harrison B L, Rosenzweig-Lipson S (2007) WAY-163909 [(7bR,10aR)-1,2,3,4,8,9,10,10a-octahydro-7bH-cyclopenta-[b][1,4]diazepino[6,7,1hi]indole]: A novel 5-hydroxytryptamine 2C receptor-selective agonist with preclinical antipsychotic-like activity. J Pharmacol Exp Ther 320:486-496.]. Therefore it is expected that 5-HT2C receptor agonists will selectively decrease mesolimibic dopamine levels without affecting the nigrostriatal pathway thus avoiding the EPS side effects of typical antipsychotics. Several 5-HT2C receptor agonists have shown antipsychotic activity in animal models of schizophrenia without EPS based on the lack of effect in catalepsy [Marquis K L, Sabb A L, Logue S F, Brennan J A, Piesla M J, Comery T A, Grauer S M, Ashby C R, Jr., Nguyen H Q, Dawson L A, Barrett J E, Stack G, Meltzer H Y, Harrison B L, Rosenzweig-Lipson S (2007) WAY-163909 [(7bR,10aR)-1,2,3,4,8,9,10,10a-octahydro-7bH-cyclopenta-[b][1,4]diazepino[6,7,1hi]indole]: A novel 5-hydroxytryptamine 2C receptor-selective agonist with preclinical antipsychotic-like activity. J Pharmacol Exp Ther 320:486-496. Siuciak J A, Chapin D S, McCarthy S A, Guanowsky V, Brown J, Chiang P, Marala R, Patterson T, Seymour P A, Swick A, Iredale P A (2007) CP-809,101, a selective 5-HT2C agonist, shows activity in animal models of antipsychotic activity. Neuropharmacology 52:279-290]. The antipsychotic activity of 5-HT2C receptor agonists without EPS coupled with their beneficial effects in mood disorders and cognition and their antiobesity like effects render 5-HT2C receptor agonists as unique agents to treat schizophrenia [Rosenzweig-Lipson S, Dunlop J, Marquis K L (2007) 5-HT2C receptor agonists as an innovative approach for psychiatric disorders.

Modulation of 5HT2 receptors may be beneficial in the treatment of conditions related to bladder function, in particular, urinary incontinence. [Discovery of a novel azepine series of potent and selective 5-HT2C agonists as potential treatments for urinary incontinence. Brennan, Paul E.; Whitlock, Gavin A.; Ho, Danny K. H.; Conlon, Kelly; McMurray, Gordon. Bioorganic & Medicinal Chemistry Letters (2009), 19(17), 4999-5003.

Department of Pharmacology, University College London, London, UK. British Journal of Pharmacology (2008), 155(3), 343-356.] In particular, compounds with agonist activity at 5-HT2C have been shown to be useful in treating urinary incontinence, see for Example U.S. Patent application publications US2008/0146583 and US 2007/0225274.
Because of their binding profile, the compounds can be used for treating diseases which respond to 5-HT6 receptor ligands (or which are susceptible to treatment with a 5-HT6 receptor ligand), i.e. they are effective for treating those medical disorders or diseases in which exerting an influence on (modulating) the 5-HT6 receptors leads to an improvement in the clinical picture or to the disease being cured. Examples of these diseases are disorders or diseases of the central nervous system.
Disorders or diseases of the central nervous system are understood as meaning disorders which affect the spinal cord and, in particular, the brain. Within the meaning of the invention, the term “disorder” denotes disturbances and/or anomalies which are as a rule regarded as being pathological conditions or functions and which can manifest themselves in the form of particular signs, symptoms and/or malfunctions. While the treatment according to the invention can be directed toward individual disorders, i.e. anomalies or pathological conditions, it is also possible for several anomalies, which may be causatively linked to each other, to be combined into patterns, i.e. syndromes, which can be treated in accordance with the invention.
The disorders which can be treated in accordance with the invention are in particular disorders which respond to a modulation of the 5-HT6 receptor. They include cognitive dysfunctions, such as a deficit in memory, cognition and learning, in particular associated with Alzheimer's disease, age-related cognitive decline and mild cognitive impairment, attention deficit disorder/hyperactivity syndrome, personality disorders, such as schizophrenia, in particular cognitive deficits related with schizophrenia, affective disorders such as depression, anxiety and obsessive compulsive disorders, motion or motor disorders such as Parkinson's disease and epilepsy, migraine, sleep disorders (including disturbances of the Circadian rhythm), feeding disorders, such as anorexia and bulimia, certain gastrointestinal disorders such as Irritable Bowel Syndrome, diseases associated with neurodegeneration, such as stroke, spinal or head trauma and head injuries, such as hydrocephalus, drug addiction and obesity.
The addiction diseases include psychiatric disorders and behavioral disturbances which are caused by the abuse of psychotropic substances, such as pharmaceuticals or narcotics, and also other addiction diseases, such as addiction to gaming (impulse control disorders not elsewhere classified). Examples of addictive substances are: opioids (e.g. morphine, heroin and codeine), cocaine; nicotine; alcohol; substances which interact with the GABA chloride channel complex, sedatives, hypnotics and tranquilizers, for Example benzodiazepines; LSD; cannabinoids; psychomotor stimulants, such as 3,4-methylenedioxy-N-methylamphetamine (ecstasy); amphetamine and amphetamine-like substances such as methylphenidate and other stimulants including caffeine. Addictive substances which come particularly into consideration are opioids, cocaine, amphetamine or amphetamine-like substances, nicotine and alcohol.
With regard to the treatment of addiction diseases, particular preference is given to those compounds according to the invention of the formula (I) which themselves do not possess any psychotropic effect. This can also be observed in a test using rats, which, after having been administered compounds which can be used in accordance with the invention, reduce their self administration of psychotropic substances, for Example cocaine.
According to another aspect of the present invention, the compounds according to the invention are suitable for treating disorders whose causes can at least partially be attributed to an anomalous activity of 5-HT6 receptors.
According to another aspect of the present invention, the treatment is directed, in particular, toward those disorders which can be influenced, within the sense of an expedient medicinal treatment, by the binding of preferably exogenously administered binding partners (ligands) to 5-HT6 receptors.
The diseases which can be treated with the compounds according to the invention are frequently characterized by progressive development, i.e. the above-described conditions change over the course of time; as a rule, the severity increases and conditions may possibly merge into each other or other conditions may appear in addition to those which already exist.
The compounds of formula (I) can be used to treat a large number of signs, symptoms and/or malfunctions which are connected with the disorders of the central nervous system and, in particular, the above-mentioned conditions. These signs, symptoms and/or malfunctions include, for Example, a disturbed relationship to reality, lack of insight and ability to meet customary social norms or the demands made by life, changes in temperament, changes in individual drives, such as hunger, sleep, thirst, etc., and in mood, disturbances in the ability to observe and combine, changes in personality, in particular emotional lability, hallucinations, ego-disturbances, distractedness, ambivalence, autism, depersonalization and false perceptions, delusional ideas, chanting speech, lack of synkinesia, short-step gait, flexed posture of trunk and limbs, tremor, poverty of facial expression, monotonous speech, depressions, apathy, impeded spontaneity and decisiveness, impoverished association ability, anxiety, nervous agitation, stammering, social phobia, panic disturbances, withdrawal symptoms in association with dependency, maniform syndromes, states of excitation and confusion, dysphoria, dyskinetic syndromes and tic disorders, e.g. Huntington's chorea and Gilles-de-la-Tourette's syndrome, vertigo syndromes, e.g. peripheral positional, rotational and oscillatory vertigo, melancholia, hysteria, hypochondria and the like.
Within the meaning of the invention, a treatment also includes a preventive treatment (prophylaxis), in particular as relapse prophylaxis or phase prophylaxis, as well as the treatment of acute or chronic signs, symptoms and/or malfunctions. The treatment can be orientated symptomatically, for Example as the suppression of symptoms. It can be effected over a short period, be orientated over the medium term or can be a long-term treatment, for Example within the context of a maintenance therapy.
The compounds according to the invention are preferentially suitable for treating diseases of the central nervous system, more preferably for treating cognitive dysfunctions and in particular, for treating cognitive dysfunctions associated with schizophrenia or with Alzheimer's disease.
According to another aspect of the invention the compounds of formula (I) are particularly suitable for treating addiction diseases caused for instance by the abuse of psychotropic substances, such as pharmaceuticals, narcotics, nicotine or alcohol, including psychic disorders and behavioral disturbances related thereto.
According to another aspect of the invention the compounds of formula (I) are particularly suitable for treating nutritional disorders, such as obesity, as well as diseases related thereto, such as cardiovascular diseases, digestive diseases, respiratory diseases, cancer or type 2 diabetes.
Within the context of the treatment, the use according to the invention of the described compounds involves a method. In this method, an effective quantity of one or more compounds, as a rule formulated in accordance with pharmaceutical and veterinary practice, is administered to the individual to be treated, preferably a mammal, in particular a human being, productive animal or domestic animal. Whether such a treatment is indicated, and in which form it is to take place, depends on the individual case and is subject to medical assessment (diagnosis) which takes into consideration signs, symptoms and/or malfunctions which are present, the risks of developing particular signs, symptoms and/or malfunctions, and other factors.
Actual dosage levels of active ingredients in the pharmaceutical compositions of the present invention can be varied so as to obtain an amount of the active compound(s) that is effective to achieve the desired therapeutic response for a particular subject (e.g., a mammal, preferably, a human (patient)), compositions and mode of administration. The selected dosage level will depend upon the activity of the particular compound, the route of administration, the severity of the condition being treated and the condition and prior medical history of the patient being treated. However, it is within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.
Compounds of the present invention can also be administered to a subject as a pharmaceutical composition comprising the compounds of interest in combination with at least one pharmaceutically acceptable carriers. The phrase “therapeutically effective amount” of the compound of the present invention means a sufficient amount of the compound to treat disorders, at a reasonable benefit/risk ratio applicable to any medical treatment. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well-known in the medical arts. For Example, it is well within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.
The total daily dose of the compounds of this invention administered to a subject (namely, a mammal, such as a human) ranges from about 0.01 mg/kg body weight to about 100 mg/kg body weight. More preferable doses can be in the range of from about 0.01 mg/kg body weight to about 30 mg/kg body weight. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions may contain such amounts or submultiples thereof to make up the daily dose.
e. Pharmaceutical Compositions
In yet another embodiment, the present invention provides pharmaceutical compositions. The pharmaceutical compositions of the present invention comprise the compounds of the present invention or a pharmaceutically acceptable salt or solvate thereof. The pharmaceutical compositions of the present invention comprise compounds of the present invention that can be formulated together with at least one non-toxic pharmaceutically acceptable carrier.
In yet another embodiment, the present invention provides a pharmaceutical composition comprising compounds of the present invention, or a pharmaceutically acceptable salt thereof, and one or more pharmaceutically acceptable carriers, alone or in combination with one or more compounds that are not the compounds of the present invention. Examples of one or more compounds that can be combined with the compounds of the present invention in pharmaceutical compositions, include, but are not limited to, one or more cognitive enhancing drugs.
The pharmaceutical compositions of this present invention can be administered to a subject (e.g., a mammal, such as a human) orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments or drops), bucally or as an oral or nasal spray. The term “parenterally” as used herein, refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous and intraarticular injection and infusion.
The term “pharmaceutically acceptable carrier” as used herein, means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some Examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as, but not limited to, lactose, glucose and sucrose; starches such as, but not limited to, corn starch and potato starch; cellulose and its derivatives such as, but not limited to, sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as, but not limited to, cocoa butter and suppository waxes; oils such as, but not limited to, peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols; such a propylene glycol; esters such as, but not limited to, ethyl oleate and ethyl laurate; agar; buffering agents such as, but not limited to, magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as, but not limited to, sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.
Pharmaceutical compositions of the present invention for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), vegetable oils (such as olive oil), injectable organic esters (such as ethyl oleate) and suitable mixtures thereof. Proper fluidity can be maintained, for Example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants.
These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents, for Example, paraben, chlorobutanol, phenol sorbic acid and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.
In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
The injectable formulations can be sterilized, for Example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.
Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the active compound may be mixed with at least one inert, pharmaceutically acceptable excipient or carrier, such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol and silicic acid; b) binders such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose and acacia; c) humectants such as glycerol; d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates and sodium carbonate; e) solution retarding agents such as paraffin; f) absorption accelerators such as quaternary ammonium compounds; g) wetting agents such as cetyl alcohol and glycerol monostearate; h) absorbents such as kaolin and bentonite clay and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such carriers as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
The solid dosage forms of tablets, dragees, capsules, pills and granules can be prepared with coatings and shells such as enteric coatings and other coatings well-known in the pharmaceutical formulating art. They may optionally contain opacifying agents and may also be of a composition such that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.
The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned carriers.
Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for Example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan and mixtures thereof.
Besides inert diluents, the oral compositions may also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring and perfuming agents.
Suspensions, in addition to the active compounds, may contain suspending agents as, for Example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, tragacanth and mixtures thereof.
Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating carriers or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
Compounds of the present invention can also be administered in the form of liposomes. As is known in the art, liposomes are generally derived from phospholipids or other lipid substances. Liposomes are formed by mono- or multi-lamellar hydrated liquid crystals which are dispersed in an aqueous medium. Any non-toxic, physiologically acceptable and metabolizable lipid capable of forming liposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients and the like. The preferred lipids are natural and synthetic phospholipids and phosphatidyl cholines (lecithins) used separately or together.
Methods to form liposomes are known in the art. See, for Example, Prescott, Ed., Methods in Cell Biology, Volume XIV, Academic Press, New York, N.Y. (1976), p. 33 et seq.
Dosage forms for topical administration of a compound of the present invention include powders, sprays, ointments and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives, buffers or propellants which may be required. Ophthalmic formulations, eye ointments, powders and solutions are also contemplated as being within the scope of this invention.
The compounds of the present invention can be used in the form of pharmaceutically acceptable salts derived from inorganic or organic acids. The phrase “pharmaceutically acceptable salt” means those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like and are commensurate with a reasonable benefit/risk ratio.
Pharmaceutically acceptable salts are well known in the art. For Example, S. M.
Berge et al. describe pharmaceutically acceptable salts in detail in (J. Pharmaceutical Sciences, 1977, 66: 1 et seq.). The salts can be prepared in situ during the final isolation and purification of the compounds of the invention or separately by reacting a free base function with a suitable organic acid.

Pharmaceutically acceptable salts include, but are not limited to, cations based on alkali metals or alkaline earth metals such as, but not limited to, lithium, sodium, potassium, calcium, magnesium and aluminum salts and the like and nontoxic quaternary ammonia and amine cations including ammonium, tetramethylammonium, tetraethylammonium, methylammonium, dimethylammonium, trimethylammonium, triethylammonium, diethylammonium, ethylammonium and the like. Other representative organic amines useful for the formation of base addition salts include ethylenediamine, ethanolamine, diethanolamine, piperidine, piperazine and the like.
The term “pharmaceutically acceptable prodrug” or “prodrug” as used herein, represents those prodrugs of the compounds of the present invention which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use.
The present invention also contemplates compounds of the present invention formed by synthetic means or formed by in vivo biotransformation of a prodrug.
The compounds of the present invention can exist in unsolvated as well as solvated forms, including hydrated forms, such as hemi-hydrates. In general, the solvated forms, with pharmaceutically acceptable solvents such as water and ethanol among others are equivalent to the unsolvated forms for the purposes of the invention.

(3aS,10bS)-8-Chloro-2-methyl-1,2,3,3a,4,5-hexahydrobenzo[e]pyrrolo[3,4-c]azepin-6(10bH)-one: Preparation of seed crystals
The seeds used in the experiment described in the patent were obtained from a previous experiment that employed the application of seeds that were obtained in a previous experiment that employed the application of seeds, and so on. The same experiment can be carried out without seeding, to the detriment of the enantiomeric purity of product: A 4 mL septum-equipped vial was charged with dibenzoyl-D-tartaric acid (72 mg, 0.20 mmol, 1.0 equiv), methanol (0.5 mL) and a magnetic stir bar. To the stirring salt was quickly charged a 0.1 g/mL ethanolic solution of the Example 53 (0.5 mL=50 mg, 0.20 mmol, 1.0 equiv). The solution was allowed to stir overnight. Solid formation made the solution unstirrable, thus methanol was added (2.0 mL). The solid was collected by filtration to provide the title compound as the dibenzoyl-D-tartrate, and the cake and filtrate were analyzed by both chiral and achiral HPLC system. Analysis using the previously described chiral method reveals the desired product to be in 84% ee.
