GAL3 receptor antagonists for the treatment of affective disorders

BACKGROUND OF THE INVENTION

[0003] The symptomatology and diagnostic criteria for affective disorders, particularly depressive disorders and anxiety disorders, are set out in Diagnostic and Statistical Manual of Mental Disorders. 4th ed. (DSM-IV; American Psychiatric Association, 1994a) or Diagnostic and Statistical Manual of Mental Disorders. 3rd ed. Revised (DSM-III-R; American Psychiatric Association, 1987). The key features of depressive illness are a markedly gloomy mood in which there is a loss of interest in life, and general feelings of hopelessness and worthlessness. Depressive symptoms range in severity from mild mood swings to severe delusions about self-worth, accomplishments, and the future.

[0004] The “blackness” of the presentation in the depressed patient is most often accompanied by severe motor retardation with profound sleep and appetite disturbance and suicidal ideation. Furthermore, depressive illness can also present in a highly anxious or agitated state. The key clinical features of anxiety disorders relate to various combinations of psychological and physical manifestations of anxiety, not attributable to real danger and occurring either in attacks (panic disorder—PD) or as a persisting state (generalized anxiety disorder—GAD). Other neurotic features may be present (obsessional or hysterical symptoms) but do not dominate the clinical picture.

[0005] The degree to which the underlying brain mechanisms in depressive and anxiety disorders differ or overlap remains unknown. The fact, however, that to some extent the same neurotransmitter systems are involved in depression and anxiety does not mean that the mechanisms are identical. However, the majority of people in an episode of either depressive illness or anxiety also meet criteria for at least one other psychiatric disorder. But by far the strongest comorbidities in both cases are the affective disorders, for example between depressive and anxiety disorders. Therefore, it is now becoming common clinical practice to treat both indications with antidepressants such as SSRIs.

[0006] Evidence implicating the role of neurotransmitters in depressive and anxiety disorders, in particular the monoamines serotonin, noradrenaline and dopamine, is enhanced by the success of pharmacological agents in treating depressive and anxiety disorders. Many of the tricylic antidepressants (TCAs), selective serotonin re-uptake inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs) effective in the treatment of depressive illness increase the availability of the catecholamines (noradrenaline and dopamine) and indolamines (serotonin) in the central nervous system (CNS). The clinical efficacy of these agents has given rise to the catecholamine-indolamine hypothesis of depressive illness. This theory postulates that a certain level of amines and/or receptor sensitivity to catecholamines functions to generate a normal mood. A receptor insensitivity, a depletion of monoamines, or a decrease in their release, synthesis or storage have been postulated to lead to depressive and anxiety disorders.

[0007] There is now considerable direct evidence for the efficacy of the SSRIs in affective disorders, i.e. depressive and anxiety disorders. Of the current SSRIs indicated as antidepressants, all have shown sufficient efficacy to be further approved for the treatment of at least one anxiety disorder. For example, fluoxetine (Prozac™) is indicated for depression and obsessive-compulsive disorder (OCD); and paroxetine (Paxil™) is indicated for panic disorder, social anxiety disorder (also known as social phobia), OCD and generalized anxiety disorder (GAD). Sertraline is also indicated for the treatment of panic disorder (PD).

[0008] Adverse effects of agents indicated to treat affective disorders include sexual dysfunction, primarily anorgasmia and delayed ejaculation. Other, common side-effects include sleep disorders, yawning, weight changes, suicidal ideation and extrapyramidal-like side-effects such as dystonic reactions. Thus, there clearly remains a medical need for novel approaches for the treatment of affective disorders, without the adverse side-effect profile of existing agents and with improved efficacy.

[0009] Discovery Of GAL3 Receptor Subtype And Its Role In Affective Disorders

[0010] The investigations leading to the present invention arose from the discovery that mRNA for the GAL3 receptor is localized to areas of the rat brain associated with mood and emotion (see PCT International Publication No. WO 98/15570, published Apr. 16, 1998), thus supporting the expression of GAL3 in those regions. Protein for the GAL3 receptor is also shown to localize to areas of the rat brain associated with mood and emotion (see Table 12 and discussion herein).

[0011] This discovery led to the hypothesis that the GAL3 receptor may play a role in controlling the activity of catecholamine and indolamine neurons in the CNS. Galanin is known to hyperpolarize neurons, including monoaminergic neurons (Seutin, et al., 1989) and to have inhibitory effects on 5-HT neurons (Xu, et al., 1998), and dopamine neurons (Gopalan, et al., 1993; De Weille, et al., 1989; Jansson, et al., 1989; Nordstrom, et al., 1987; Weiss, et al., 1998). In light of these reports, a series of in vivo behavioral experiments were carried out to evaluate the properties of a selective GAL3 receptor antagonist. The rat Forced Swim Test and the rat Social Interaction Test were employed to evaluate the use of selective GAL3 receptor antagonists to treat affective disorders. These models are considered by experts in the field to reflect the potential of antidepressant-like and anxiolytic-like agents used to treat affective disorders.

[0012] Rat Forced Swim Test (FST)

[0013] The rat Forced Swim Test (FST) is a behavioral test that is used to screen compounds for antidepressant efficacy (Porsolt et al., 1977, 1978; Porsolt, 1981). This test is widely used as it is reliable across laboratories, relatively easy to perform and is sensitive to the effects of some of the major classes of antidepressant drugs, including TCAs and MAOIs, and various a typical antidepressants. Furthermore, this test is relatively selective for antidepressant drugs, as few psychoactive drugs produce similar behavioral actions in the FST.

[0014] In the rat FST, animals are placed in a cylinder of water, from which there is no escape, for an extended period of time. Typically, animals will display a range of behaviors such as immobility, climbing, swimming, and diving, with immobility being predominant after several minutes of immersion in the water. Consequently, many past studies have only measured or scored immobility after the administration of the test agent. Unfortunately, this method does not score any other active behaviors that may be produced by potential antidepressants. Thus, if a particular class of antidepressant were to have very little effect on immobility, yet produce characteristic behaviors during the FST, these behaviors would not be scored and the conclusion would be that the compound in question does not possess antidepressant action.

[0015] Recently, however, a sampling technique was developed to score active behaviors in the FST, such as swimming, climbing and diving, in addition to immobility (Detke, et al., 1995; Lucki, 1997; Page, et al., 1999; Reneric and Lucki, 1998). This modified sampling technique has indicated that SSRIs, such as fluoxetine, paroxetine and sertraline, significantly decrease immobility and increase swimming time (Detke, et al., 1995; Page, et al., 1999). In contrast, selective reuptake inhibitors of norepinephrine (NE) increase climbing behavior but do not alter swimming time (Detke, et al., 1995; Page, et al., 1999).

[0016] Rat Social Interaction Test (SIT)

[0017] There are a number of paradigms that have been used to determine whether a compound possesses anxiolytic-like action. A number of these tests involve food or water deprivation, punishment or measurement of consummatory behavior (see File, et al., 1980; File, 1985; Rodgers, et al., 1997; and Treit, 1985, for review). In addition, in these models, prior conditioning reduces the uncertainty or anxiety. In general, these tests lack ethological validity.

[0018] One model that is based upon an unconditioned response that does not involve punishment or deprivation is the Social Interaction Test (SIT) (File and Hyde, 1978, 1979). In this model, rats previously housed singly are placed in a familiar, dimly lit, test arena with weight-matched, novel partners. The principal anxiogenic stimulus under these conditions is the partner novelty, which involves an unconditioned response to a potential threat. After pharmacological treatments, the following behaviors are scored as active social interaction: grooming, sniffing, biting, boxing, wrestling, following, crawling over and crawling under. A wide range of psychoactive drugs have been examined in this paradigm and it has been shown that the social interaction test can distinguish anxiolytics from antidepressants, antipsychotics, analeptics and sedative agents (File, 1985; Guy and Gardner, 1985). This test can detect anxiolytic agents such as the benzodiazepines (File and Hyde, 1978; File and Hyde, 1979; File, 1980), in addition to non-benzodiazepines, including paroxetine and other SSRIs (Lightowler, et al., 1994). Finally, the social interaction test can detect anxiogenic agents, including the inverse benzodiazepine receptor agonists (File, et al., 1982; File and Pellow, 1983; File and Pellow, 1984; File, 1985).

[0019] Drugs useful in treating affective disorders are evaluated for good-face validity, good-costruct validity, and good-predictive validity based on the animal models mentioned above and the known activity of clinically effective drugs in these models.

[0020] In an embodiment of the present invention the synthesis of novel pyrimidines which bind selectively to the cloned human GAL3 receptor, compared to other cloned human G-protein coupled receptors, as measured in in vitro assays, is disclosed. In a further embodiment of the present invention the synthesis of indolones which bind selectively to the cloned human GAL3 receptor, compared to other cloned human G-protein coupled receptors, as measured in in vitro assays, is disclosed. The in vitro receptor assays described hereinafter were performed using various cultured cell lines, each transfected with and expressing only a single galanin-type receptor.

[0021] From the binding information described hereinafter, it has unexpectedly been discovered that compounds which are specific for the human GAL3 receptor with a binding affinity greater than ten-fold higher than the binding affinity with which the compounds bind to a human GAL1 receptor are effective in animal models which are predictive of antidepressant-like and anxiolytic-like activity in humans. Thus, we demonstrate that the GAL3 receptor antagonists, which may be classified as neutral antagonists, inverse agonists or allosteric modulators, provide a novel method to treat affective disorders.

BRIEF DESCRIPTION OF THE FIGURES

[0199]
FIG. 1: Rat Forced Swim Test Results (Immobility: Normal Rats)

[0200] Vehicle (V) and test compounds (F10=fluoxetine at 10 mg/kg ip; C1, C3, C10 or C30=Example 92 at 1, 3, 10 or 30 mg/kg ip) were injected into normal rats by intraperitonal administration (n=5 for each treatment condition). One hour later, rats were examined in a 5 minute forced swim test. For each treatment condition, the number of 5-sec intervals culminating with a display of immobility was derived and plotted as the average +/−S.E.M. A significant decrease in immobility was observed for rats injected with fluoxetine at 10 mg/kg, or with Example 92 at 3 and 10 mg/kg, relative to vehicle injected controls (p<0.01, ANOVA and Student-Nerman-Keuls).

[0201]
FIG. 2: Rat Forced Swim Test Results (Climbing: Normal Rats)

[0202] Vehicle (V) and test compounds (F10=fluoxetine at 10 mg/kg ip; C1, C3, C10 or C30=Example 92 at 1, 3, 10 or 30 mg/kg ip) were injected into normal rats by intraperitonal administration (n=5 for each treatment condition). One hour later, rats were examined in a 5 minute forced swim test. For each treatment condition, the number of 5-sec intervals culminating with a display of climbing was derived and plotted as the average +/−S.E.M. A significant increase in climbing was observed for rats injected with Example 92 at 10 mg/kg, relative to vehicle injected controls (p<0.01, ANOVA and Student-Nerman-Keuls), but not in rats dosed with Example 92 at 30 mg/kg ip.

[0203]
FIG. 3: Rat Forced Swim Test Results (Swimming: Normal Rats)

[0204] Vehicle (V) and test compounds (F10=fluoxetine at 10 mg/kg ip; C1, C3, C10 or C30=Example 92 at 1, 3, 10 or 30 mg/kg ip) were injected into normal rats by intraperitonal administration (n=5 for each treatment condition). One hour later, rats were examined in a 5 minute forced swim test. For each treatment condition, the number of 5-sec intervals culminating with a display of swimming was derived and plotted as the average +/−S.E.M. A significant increase in swimming was observed for rats injected with fluoxetine at 10 mg/kg ip or with Example 92 at 30 mg/kg, relative to vehicle injected controls (p<0.01, ANOVA and Student-Nerman-Keuls).

[0205]
FIG. 4: Social Interaction Test Results (Social Interaction: Unfamiliar Rats)

[0206] Vehicle (V) and test compounds (CLD 5=chlordiazepoxide at 5 mg/kg ip; C10, C30 or C100=Example 92 at 10, 30 or 100 mg/kg ip) were injected into normal rats by intraperitonal administration (n=5 for each treatment condition). One hour later, unfamiliar rats were examined in a 15 minute social interaction test. For each treatment condition, the amount of time spent in social interaction was derived and plotted as the average +/−S.E.M. A significant increase in social interaction was observed for rats injected with chlordiazepoxide at 5 mg/kg i.p. or with Example 92 at 10 mg/kg ip (p<0.05) as well as 30 mg/kg (p<0.01). When the dose of Example 92 was increased to 100 mg/kg, the amount of social interaction time was significantly less than measured after chlordiazepoxide at 5 mg/kg ip or Example 92 at 30 mg/kg ip (p<0.01). Significance in all cases was determined by ANOVA and Student-Nerman-Keuls.

[0207]
FIG. 5: Western Blot Results

[0208] In order to establish the specificity of the anti-GAL3 antiserum, membranes prepared from COS-7 cells transiently transfected with the rat recombinant GAL3 (Borowsky et al., 1999) (Lane 2) or mock-transfected (vector only) (Lane 3) were applied to an SDS-PAGE gel and blotted using the GAL3 receptor polyclonal antibody. Lane 1 corresponds to molecular weight marker. The anti-GAL3 antiserum labeled proteins in membranes only from rat GAL3-transfected cells (Lane 2); a predominant band was evident with an apparent molecular weight of approximately 56 kDa, (somewhat higher than the amino acid-derived value of 40.4 kDa). The apparently high molecular weight observed for rat GAL3 very likely reflects post-translational processing such as glycosylation; note that rat GAL3 contains multiple N-terminal glycosylation sites (Smith et al., 1998). Relative to the predominant band, additional species of higher molecular weight as well as lower molecular weight were labeled by the GAL3 antiserum. These are interpreted as protein aggregates of C-terminal fragments, as they are absent in mock-transfected cells.

[0499] The following description of affective disorders is provided for the purpose of facilitating an understanding of the utility of the compounds of this invention. The definitions of affective disorders given below, i.e. depressive and anxiety disorders, are those listed in Diagnostic and Statistical Manual of Mental Disorders. 4th ed. (DSM-IV; American Psychiatric Association, 1994a) or Diagnostic and Statistical Manual of Mental Disorders. 3rd ed. Revised (DSM-III-R; American Psychiatric Association, 1987). Additional information regarding these disorders can be found in this reference, as well as other references cited below, all of which are hereby incorporated herein by reference.

[0500] Depressive disorders include major depressive disorder and dysthymic disorder (American Psychiatric Association, 1994a; American Psychiatric Association, 1994b). Major depressive disorder is characterized by the occurrence of one or more major depressive episodes without manic or hypomanic episodes. A major depressive episode is defined as a prominent and relatively persistent depressed or dysphoric mood that usually interferes with daily functioning (nearly every day for at least 2 weeks); it should include at least 4 of the following 8 symptoms: change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and a suicide attempt or suicidal ideation (Medical Economics Company, 2002). Dysthymic disorder involves a type of depressive disorder that is not severe enough to be called a major depressive episode, but that lasts much longer than major depressive disorder, without high phases.

[0501] It is contemplated that the compounds of this invention will be effective in treating an affective disorder, specifically a depressive disorder, in patients who have been diagnosed as having such depressive disorder based upon the administration of any of the following tests: Hamilton Depression Rating Scale (HDRS), Hamilton depressed mood item, Clinical Global Impressions (CGI)-Severity of Illness. It is further contemplated that the compounds of the invention will be effective in inducing improvements in certain of the factors measured in these tests, such as the HDRS subfactor scores, including the depressed mood item, sleep disturbance factor and anxiety factor, and the CGI-Severity of Illness rating. It is also contemplated that the compounds of this invention will be effective in preventing relapse of major depressive episodes.

[0502] Anxiety disorders include panic disorder, agoraphobia with or without history of panic disorder, specific phobia, social phobia, obsessive-compulsive disorder, post-traumatic stress disorder, acute stress disorder and generalized anxiety disorder. It is contemplated that the compounds of this invention will be effective in treating these disorders in patients who have been diagnosed as having such disorders.

[0503] Obsessive-compulsive disorder is characterized by recurrent and persistent ideas, thoughts, impulses or images (obsessions) that are ego-dystonic and/or repetitive, purposeful and intentional behaviors (compulsions) that are recognized by the person as excessive or unreasonable (American Psychiatric Association, 1994a). The obsessions cr compulsions cause marked distress, are time-consuming, and/or significantly interfere with social or occupational functioning.

[0504] It is contemplated that the compounds of this invention will be effective in treating obsessions and compulsions in patients who have been diagnosed as having obsessive compulsive disorder based upon administration of appropriate tests, which may include, but are not limited to any of the following: Yale Brown Obsessive Compulsive Scale (YBOCS) (Goodman, 1989) (for adults), National Institute of Mental Health Global OCD Scale (NIMH GOCS), CGI-Severity of Illness scale. It is further contemplated that the compounds of the invention will be effective in inducing improvements in certain of the factors measured in these tests, such as a reduction of several points in the YBOCS total score. It is also contemplated that the compounds of this invention will be effective in preventing relapse of obsessive compulsive disorder.

[0505] Panic disorder is characterized by recurrent unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks (American Psychiatric Association, 1994a). A panic attack is defined as a discrete period of intense fear or discomfort in which four (or more) of the following symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, pounding heart, or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded, or faint; (9) derealization (feelings of unreality) or depersonalization (being detached from oneself); fear of losing control; (11) fear of dying; (12) paresthesias (numbness or tingling sensations); (13) chills or hot flushes. Panic disorder may or may not be associated with agoraphobia, or an irrational and often disabling fear of being put in public.

[0506] It is contemplated that the compounds of this invention will be effective in treating panic disorder in patients who have been diagnosed with panic disorder on the basis of frequency of occurrence of panic attacks, or by means of the CGI-Severity of Illness scale. It is further contemplated that the compounds of the invention will be effective in inducing improvements in certain of the factors measured in these evaluations, such as a reduction in frequency or elimination of panic attacks, an improvement in the CGI-Severity of Illness scale or a CGI-Global Improvement score of 1 (very much improved), 2 (much improved) or 3 (minimally improved). It is also contemplated that the compounds of this invention will be effective in preventing relapse of panic disorder.

[0507] Social anxiety disorder, also known as social phobia, is characterized by a marked and persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others (American Psychiatric Association, 1994a). Exposure to the feared situation almost invariably provokes anxiety, which may approach the intensity of a panic attack. The feared situations are avoided or endured with intense anxiety or distress. The avoidance, anxious anticipation, or distress in the feared situation(s) interferes significantly with the person's normal routine, occupational or academic functioning, or social activities or relationships, or there is marked distress about having the phobias. Lesser degrees of performance anxiety or shyness generally do not require psychopharmacological treatment.

[0508] It is contemplated that the compounds of this invention will be effective in treating social anxiety disorder in patients who have been diagnosed with social anxiety disorder by administration of any of the following tests: the Liebowitz Social Anxiety Scale (LSAS), the CGI-Severity of Illness scale, the Hamilton Rating Scale for Anxiety (HAM-A), the Hamilton Rating Scale for Depression (HAM-D), the axis V Social and Occupational Functioning Assessment Scale of DSM-IV, the axis II (ICD-10) World Health Organization Disability Assessment, Schedule 2 (DAS-2), the Sheehan Disability Scales, the Schneier Disability Profile, the World Health Organization Quality of Life-100 (WHOQOL-100), or other tests as described in Bobes, 1998, which is incorporated herein by reference. It is further contemplated that the compounds of the invention will be effective in inducing improvements as measured by these tests, such as the a change from baseline in the Liebowitz Social Anxiety Scale (LSAS), or a CGI-Global Improvement score of 1 (very much improved), 2 (much improved) or 3 (minimally improved). It is also contemplated that the compounds of this invention will be effective in preventing relapse of social anxiety disorder.

[0509] Generalized anxiety disorder is characterized by excessive anxiety and worry (apprehensive expectation) that is persistent for at least 6 months and which the person finds difficult to control (American Psychiatric Association, 1994a). It must be associated with at least 3 of the following 6 symptomts: restlessness or feeling keyed up or on edge, being easily fatigued, difficulty concentrating or mind going blank, irritability, muscle tension, sleep disturbance. The diagnostic criteria for this disorder are described in further detail in DSM-IV, which is incorporated herein by reference (American Psychiatric Association, 1994a).

[0510] It is contemplated that the compounds of this invention will be effective in treating generalized anxiety disorder in patients who have been diagnosed with this disorder according to the diagnostic criteria described in DSM-IV. It is further contemplated that the compounds of the invention will be effective in reducing symptoms of this disorder, such as the following: excessive worry and anxiety, difficulty controlling worry, restlessness or feeling keyed up or on edge, being easily fatigued, difficulty concentrating or mind going blank, irritability, muscle tension, or sleep disturbance. It is also contemplated that the compounds of this invention will be effective in preventing relapse of general anxiety disorder.

[0511] Post-traumatic stress disorder (PTSD), as defined by DSM-III-R/IV (American Psychiatric Association, 1987, American Psychiatric Association, 1994a), requires exposure to a traumatic event that involved actual or threatened death or serious injury, or threat to the physical integrity of self or others, and a response which involves intense fear, helplessness, or horror. Symptoms that occur as a result of exposure to the traumatic event include re-experiencing of the event in the form of intrusive thoughts, flashbacks or dreams, and intense psychological distress and physiological reactivity on exposure to cues to the event; avoidance of situations reminiscent of the traumatic event, inability to recall details of the event, and/or numbing of general responsiveness manifested as diminished interest in significant activities, estrangement from others, restricted range of affect, or sense of foreshortened future; and symptoms of autonomic arousal including hypervigilance, exaggerated startle response, sleep disturbance, impaired concentration, and irritability or outbursts of anger. A PTSD diagnosis requires that the symptoms are present for at least a month and that they cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

[0512] It is contemplated that the compounds of this invention will be effective in treating PTSD in patients who have been diagnosed with PTSD by administration of any of the following tests: Clinician-Administered PTSD Scale Part 2 (CAPS), the patient-rated Impact of Event Scale (IES) (Medical Economics Company, 2002, p. 2752). It is further contemplated that the compounds of the invention will be effective in inducing improvements in the scores of the CAPS, IES, CGI-Severity of Illness or CGI-Global Improvement tests. It is also contemplated that the compounds of this invention will be effective in preventing relapse of PTSD.

[0513] The invention provides for each pure stereoisomer of any of the compounds described herein. Such stereoisomers may include enantiomers, diastereomers, or E or Z alkene or imine isomers. The invention also provides for stereoisomeric mixtures, including racemic mixtures, diastereomeric mixtures, or E/Z isomeric mixtures. Stereoisomers can be synthesized in pure form (Nógrádi, M.; Stereoselective Synthesis, (1987) VCH Editor Ebel, H. and Asymmetric Synthesis, Volumes 3-5, (1983) Academic Press, Editor Morrison, J.) or they can be resolved by a variety of methods such as crystallization and chromatographic techniques (Jaques, J.; Collet, A.; Wilen, S.; Enartiomer, Racemates, and Resolutions, 1981, John Wiley and Sons and Asymmetric Synthesis, Vol. 2, 1983, Academic Press, Editor Morrison, J).

[0514] In addition the compounds of the present invention may be present as enantiomers, diasteriomers, isomers or two or more of the compounds may be present to form a racemic or diastereomeric mixture.

The acids and bases from which these salts are prepared include but are not limited to the acids and bases listed herein. The acids include, but are not limited to, the following inorganic acids: hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid and boric acid. The acids include, but are not limited to, the following organic acids: acetic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, maleic acid, citric acid, methanesulfonic acid, benzoic acid, glycolic acid, lactic acid and mandelic acid.

[0517] The present invention includes within its scope prodrugs of the compounds of the invention. In general, such prodrugs will be functional derivatives of the compounds of the invention which are readily convertible in vivo into the required compound. Thus, in the present invention, the term “administering” shall encompass the treatment of the various conditions described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in Design of Prodrugs, ed. H. Bundgaard, Elsevier, 1985.

[0518] The present invention further includes metabolites of the compounds of the present invention. Metabolites include active species produced upon introduction of compounds of this invention into the biological milieu.

[0519] Throughout the invention, the term “binding affinity” describes the concentration of a compound required to occupy one-half of the binding sites in a receptor population, as detectable by radioligand binding. Binding affinity concentration can be represented as Ki, inhibition constant, or KD, dissociation constant.

[0520] The term “selectivity of binding affinity” refers to the ability of a chemical compound to discriminate one receptor from another. For example, a compound showing selectivity for receptor A versus receptor B will bind receptor A at lower concentrations than those required to bind receptor B.

[0521] Therefore, the statements of the form “binds to the GAL3 receptor with a binding affinIty at least ten-fold higher than” a named receptor, indicates that the binding affinity at the GAL3 receptor is at least ten-fold greater than that for a named receptor, and binding affinity measurements (i.e. Ki or KD) for the compound are at least ten-fold lower in numerical value.

[0522] The present invention provides a method of treating an abnormality in a subject which comprises administering to the subject a composition comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of a GAL3 receptor antagonist, wherein:

[0523] the GAL3 receptor antagonist binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human GALL receptor.

[0524] In some embodiments of this invention, the GAL3 receptor antagonist binds to the human GAL3 receptor with a binding affinity at least 30-fold higher than the binding affinity with which it binds to the human GAL1 receptor.

[0525] In further embodiments of the invention, the GAL3 receptor antagonist binds to the human GAL3 receptor with a binding affinity at least 50-fold higher than the binding affinity with which it binds to the human GALL receptor.

[0526] In other embodiments of the invention, the GAL3 receptor antagonist binds to the human GAL3 receptor with a binding affinity at least 100-fold higher than the binding affinity with which it binds to the human GAL1 receptor.

[0527] In still other embodiments of the invention, the GAL3 receptor antagonist binds to the human GAL3 receptor with a binding affinity at least 200-fold higher than the binding affinity with which it binds to the human GAL1 receptor.

[0528] For the purposes of this invention the term “pharmaceutically acceptable carrier” has been defined herein.

[0529] The term “antagonist” refers to a compound which binds to, and decreases the activity of, a receptor in the presence of an agonist. In the case of a G-protein coupled receptor, activation may be measured using an appropriate second messenger system which is coupled to the receptor in a cell or tissue in which the receptor is expressed. Some specific but by no means limiting examples of well-known second messenger systems are adenylate cyclase, intracellular calcium mobilization, ion channel activation, guanylate cyclase, inositol phospholipid hydrolysis, and MAP kinase activation. Conversely, the term “agonist” refers to a compound which binds to, and increases the activity of, a receptor as compared with the activity of the receptor in the absence of any agonist. Methods to perform second messenger assays are described in PCT International Publication No. 97/46250 and in PCT International Publication No. 98/15570, the contents of which are hereby incorporated by reference.

[0530] In the case that a receptor has activity in the absence of an agonist (constitutive receptor activity) the antagonist may act as an inverse agonist or an allosteric modulator, as opposed to a neutral antagonist, and suppress receptor signaling independent of the agonist (Lutz and Kenakin, 1999). The categories of “antagonist compounds” are therefore seen to include 1) neutral antagonists (which block agonist actions but do not affect constitutive activity); 2) inverse agonists (which block agonist actions as well as constitutive activity by stabilizing an inactive receptor conformation); 3) and allosteric modulators (which block agonist actions to a limited extent and which may also block constitutive activity through allosteric regulation). The probability that an antagonist is neutral and therefore of “zero efficacy” is relatively low, given that this would require identical affinities for different tertiary conformations of the receptor. Thus, Kenakin proposed in 1996 that, “with the development of sensitive test systems for the detection of inverse agonism will come a reclassification of many drugs. It might be observed that numerous previously classified neutral antagonists may be inverse agonists” (Kenakin, 1996). Indeed, there is now evidence from studies with known pharmacological agents to support the existence of inverse agonists for numerous receptors, including histamine, 5HT1A, 5HT2C, cannabinoid, dopamine, calcitonin and human formyl peptide receptors, among others (de Ligt, et al, 2000; Herrick-Davis, et al, 2000; Bakker, et al, 2000). In the case of the 5HT2C receptor, clinically effective a typical antipsychotics drugs such as sertindole, clozapine, olanzapine, ziprasidone, risperidone, zotepine, tiospirone, fluperlapine and tenilapine displayed potent inverse activity whereas typical antipsvchotic drugs such as chlorpromazine, thioridazine, spiperone and thiothixene were classified as neutral antagonists (Herrick-Davis et al, 2000). In the case of the histamine H1 receptor, the therapeutically used anti-allergics cetirizine, loratadine and epinastine were found to be inverse agonists. These findings further extend the idea that many compounds previously thought of as neutral antagonists will be reclassified as inverse agonists when tested in a constitutively active receptor system (de Ligt et al, 2000).

[0531] The subject invention provides GAL3 antagonists which selectively bind to the GAL3 receptor. A GAL3 antagonist useful in the treatment of pain is one which selectively binds to the GAL3 receptor, and displays analgesic activity in an animal model which is predictive of the efficacy of analgesics to treat pain in humans. Animal models used to test potential analgesic agents are well known in the art.

[0532] In order to test compounds for selective binding to the human GAL3 receptor the cloned cDNAs encoding both the human and rat GAL1 and GAL2 receptors have been used. The cloning and assay methods for the human and rat GAL1 receptors may be found in PCT International Publication No. WO 95/22608, the contents of which are hereby incorporated by reference. The cloning and assay methods for the human and rat GAL2 receptors may be found in PCT International Publication No. WO 97/26853, the contents of which are hereby incorporated by reference.

[0533] The present invention provides for a method of determining the binding affinity of a GAL3 antagonist, wherein the GAL3 antagonist is dissolved in a “suitable solvent”. A “suitable solvent” means one which permits the measurement of binding affinity of the GAL3 antagonist to the human GAL3 receptor at concentrations less than 1 μM, preferably less than 100 nM. Examples of solvents include, but are not limited to, DMSO, ethanol, N,N-dimethylacetamide, or water. For indolones, the preferred solvent is 3% DMSO (final concentration in the assay). For pyrimidines, the preferred solvent is 1% ethanol/0.09% polypuronic acid F-127 (final concentration in the assay). For any other type of compounds, the preferred solvent is the solvent which permits the measurement of binding affinity of a GAL3 antagonist at the lowest concentration. Once a suitable solvent is ascertained for the binding assay of the human GAL3 receptor, the same solvent is used in assays to determine the binding affinity for instance, at the GAL1 receptor.

[0534] In certain embodiments, the aforementioned GAL3 receptor antagonist additionally binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human GAL2 receptor.

[0535] In other embodiments, the GAL3 receptor antagonist additionally binds to the human GAL3 receptor with a binding affinity at least 30-fold higher than the binding affinity with which it binds to the human GAL2 receptor.

[0536] In still other embodiments, the GAL3 receptor antagonist additionally binds to the human GAL3 receptor with a binding affinity at least 50-fold higher than the binding affinity with which it binds to the human GAL2 receptor.

[0537] In some embodiments, the GAL3 receptor antagonist additionally binds to the human GAL3 receptor with a binding affinity at least 100-fold higher than the binding affinity with which it binds to the human GAL2 receptor.

[0538] In further embodiments, the GAL3 receptor antagonist additionally binds to the human GAL3 receptor with a binding affinity at least 200-fold higher than the binding affinity with which it binds to the human GAL2 receptor.

[0539] In other embodiments, the receptor antagonist also binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to each of the human 5HT1B, human 5HT1D, human 5HT1E, human 5HT1F, human 5HT2A, rat 5HT2C, human 5HT6 and human 5HT7 receptors.

[0540] In still another embodiment, the receptor antagonist also binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human histamine H1 receptor.

[0541] In still another embodiment, the receptor antagonist also binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human dopamine D1, D2, D3, D4 andD5 receptors.

[0542] In a further embodiment, the receptor antagonist also binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human α1A adrenoceptor, the human α1B adrenoceptor and the human α1D adrenoceptor.

[0543] In another embodiment, the receptor antagonist also binds to the human GAL3 receptor with a binding affinity at least ten-fold higher than the binding affinity with which it binds to the human α2A adrenoceptor, the human α2B adrenoceptor and the human α2C adrenoceptor.

[0544] In certain embodiments, the GAL3 receptor antagonist also binds to the human GAL3 receptor with a binding affinity less than ten-fold higher than the binding affinity with which it binds to the human 5HT4 receptor.

[0545] In further embodiments, the GAL3 receptor antagonist also binds to the human GAL3 receptor with a binding affinity less than ten-fold higher than the binding affinity with which it binds to the human 5HT1A receptor.

[0546] The binding properties of compounds at different receptors were determined using cultured cell lines that selectively express the receptor of interest.

In another embodiment, the carrier is a solid and the composition is a powder or tablet. In a further embodiment, the carrier is a gel and the composition is a capsule or suppository.

[0550] This invention provides a pharmaceutical composition made by combining a therapeutically effective amount of the compound of this invention and a pharmaceutically acceptable carrier.

[0551] This invention provides a process for making a pharmaceutical composition comprising combining a therapeutically effective amount of the compound of this invention and a pharmaceutically acceptable carrier.

[0552] In the subject invention a “therapeutically effective amount” is any amount of a compound which, when administered to a subject suffering from a disease against which the compounds are effective, causes reduction, remission, or regression of the disease. In the subject application, a “subject” is a vertebrate, a mammal, or a human.

[0553] The present invention provides for the use of any of the chemical compounds disclosed herein for the preparation of a pharmaceutical composition for treating an affective disorder. The invention also provides for the use of a chemical compound for the preparation of a pharmaceutical composition for treating an affective disorder, wherein the affective disorder is alleviated by decreasing the activity of a human GAL3 receptor.

[0554] In some embodiments, the affective disorder is a major depressive disorder, a manic depressive disorder, a dysthymic disorder, a panic disorder, social anxiety, a social phobia, a specific phobia, obsessive-compulsive disorder, post-traumatic stress disorder, acute stress disorder or generalized anxiety disorder.

[0555] In the present invention the term “pharmaceutically acceptable carrier” is any pharmaceutical carrier known to those of ordinary skill in the art as useful in formulating pharmaceutical compositions. On Dec. 24, 1997 the Food and Drug Administration of the United States Department of Health and Human Services published a guidance entitled “Q3C Impurities: Residual Solvent”. The guidance recommends acceptable amounts of residual solvents in pharmaceuticals for the safety of the patient, and recommends the use of less toxic solvents in the manufacture of drug substances and dosage forms.

[0556] In an embodiment of the present invention, the pharmaceutical carrier may be a liquid and the pharmaceutical composition would be in the form of a solution. In another embodiment, the pharmaceutically acceptable carrier is a solid and the composition is in the form of a powder or tablet. In a further embodiment, the pharmaceutical carrier is a gel and the composition is in the form of a suppository or cream. In a further embodiment the compound may be formulated as a part of a pharmaceutically acceptable transdermal patch. In yet a further embodiment, the compound may be delivered to the subject by means of a spray or inhalant.

[0557] A solid carrier can include one or more substances which may also act as endogenous carriers (e.g. nutrient or micronutrient carriers), flavoring agents, lubricants, solubilizers, suspending agents, fillers, glidants, compression aids, binders or tablet-disintegrating agents; it can also be an encapsulating material. In powders, the carrier is a finely divided solid which is in admixture with the finely divided active ingredient. In tablets, the active ingredient is mixed with a carrier having the necessary compression properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain up to 99% of the active ingredient. Suitable solid carriers include, for example, calcium phosphate, magnesium stearate, talc, sugars, lactose, dextrin, starch, gelatin, cellulose, polyvinylpyrrolidine, low melting waxes and ion exchange resins.

[0558] Liquid carriers are used in preparing solutions, suspensions, emulsions, syrups, elixirs and pressurized compositions. The active ingredient can be dissolved or suspended in a pharmaceutically acceptable liquid carrier such as water, an organic solvent, a mixture of both or pharmaceutically acceptable oils or fats. The liquid carrier can contain other suitable pharmaceutical additives such as solubilizers, emulsifiers, buffers, preservatives, sweeteners, flavoring agents, suspending agents, thickening agents, colors, viscosity regulators, stabilizers or osmoregulators. Suitable examples of liquid carriers for oral and parenteral administration include water (partially containing additives as above, e.g. cellulose derivatives, preferably sodium carboxymethyl cellulose solution), alcohols (including monohydric alcohols and polyhydric alcohols, e.g. glycols) and their derivatives, and oils (e.g. fractionated coconut oil and arachis oil). For parenteral administration, the carrier can also be an oily ester such as ethyl oleate or isopropyl myristate. Sterile liquid carriers are useful in sterile liquid form compositions for parenteral administration. The liquid carrier for pressurized compositions can be halogenated hydrocarbon or other pharmaceutically acceptable propellent.

[0559] Liquid pharmaceutical compositions which are sterile solutions or suspensions can be utilized by for example, intramuscular, intrathecal, epidural, intraperitoneal or subcutaneous injection. Sterile solutions can also be administered intravenously. The compounds may be prepared as a sterile solid composition which may be dissolved or suspended at the time of administration using sterile water, saline, or other appropriate sterile injectable medium. Carriers are intended to include necessary and inert binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings.

[0560] The compound can be administered orally in the form of a sterile solution or suspension containing other solutes or suspending agents (for example, enough saline or glucose to make the solution isotonic), bile salts, acacia, gelatin, sorbitan monoleate, polysorbate 80 (oleate esters of sorbitol and its anhydrides copolymerized with ethylene oxide) and the like.

[0561] The compound can also be administered orally either in liquid or solid composition form. Compositions suitable for oral administration include solid forms, such as pills, capsules, granules, tablets, and powders, and liquid forms, such as solutions, syrups, elixirs, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions, and suspensions.

[0562] Optimal dosages to be administered may be determined by those skilled in the art, and will vary with the particular compound in use, the strength of the preparation, the mode of administration, and the advancement of the disease condition. Additional factors depending on the particular subject being treated will result in a need to adjust dosages, including subject age, weight, gender, diet, and time of administration.

[0563] This invention will be better understood from the Experimental Details which follow. However, one skilled in the art will readily appreciate that the specific methods and results discussed are merely illustrative of the invention as described more fully in the claims which follow thereafter.

EXPERIMENTAL DETAILS

[0564] I. Synthesis of Chemical Compounds

[0565] The following examples are for the purpose of illustrating methods useful for making compounds of this invention.

[0566] General Methods: All reactions were performed under an Argon atmosphere and the reagents, neat or in appropriate solvents, were transferred to the reaction vessel via syringe and cannula techniques. Anhydrous solvents were purchased from the Aldrich Chemical Company and used as received. The examples described in the patent were named using the ACD/Name Program (version 4.01, Advanced Chemistry Development Inc., Toronto, Ontario, M5H2L3, Canada). The 1H NMR and 13C NMR spectra were recorded at either 300 MHz (GEQE Plus) or 400 MHz (Bruker Avance) in CDCl3 as solvent and tetramethylsilane as the internal standard unless otherwise noted. Chemical shifts (δ) are expressed in ppm, coupling constants (J) are expressed in Hz, and splitting patterns are described as follows: s=singlet; d=doublet; t=triplet; q=quartet; quintet; sextet; septet; br=broad; m=mutiplet; dd=doublet of doublets; dt=doublet of triplets. Elemental analyses were performed by Robertson Microlit Laboratories, Inc. Unless otherwise, mass spectra were obtained using electrospray ionization (ESI, Micromass Platform II) and MH+ is reported. Thin-layer Chromatography (TLC) was carried out on glass plates pre-coated with silica gel 60 F254 (0.25 mm, EM Separations Tech.). Preparative TLC was carried out on glass sheets pre-coated with silica gel GF (2 mm, Analtech). Flash column chromatography was performed on Merck silica gel 60 (230-400 mesh) Melting points (mp) were determined in open capillary tubes on a Mel-Temp apparatus and are uncorrected.

[0567] The following additional abbreviations are used: HOAc, acetic acid; DIPEA, diisopropylethylamine; DMF, N,N-dimethylformamide; EtOAc, ethyl acetate; MeOH, methanol; TEA, triethylamine; THF, tetrahydrofuran; All solvent ratios are volume/volume unless stated otherwise.

[0568] A. General Procedures for Preparing Pyrimidines

[0569] The compounds of this invention were prepared by sucessively displacing the three chlorine atoms of a 2,4,6-trichloropyrimidine with amines. It was found that some amines (i.e. anilines) selectively displace the 2-position chlorine of 2,4,6-trichloropyrimidine, whereas other amines (e.g. piperidine) selectively displace the 4- or 6-position chlorine first (note that the 4- and 6-positions are chemically equivalent) Some amines react non-selectively at both the 2- and 4-positions of 2,4,6-trichloropyrimidine. It was also found that if the pyrimidine is substituted at the 4- or 6-position with an amine (mono- or di-substituted, or unsubstituted), then the next amine (mono- or di-substituted) undergoes substitution at the 2-position of the pyrimidine. Thus, several different Procedures were used to obtain the compounds described by this invention.

[0863] Examples 1-90 and 115-253 as described above are merely illustrative of the methods used to synthesize pyrimidine derivatives. Further derivatives may be obtained utilizing methods shown in Schemes 1-5b. The substituents in Schemes 1-5b are described in the Detailed Description.

[0864] It may be necessary to incorporate protection and deprotection strategies for substituents such as amino, amido, carboxylic acid, and hydroxyl groups in the synthetic methods described above to form pyrimidine derivatives. Methods for protection and deprotection of such groups are well-known in the art, and may be found, for example in Green, T. W. and Wuts, P.G. M. (1991) Protection Groups in Organic Synthesis, 2nd Edition John Wiley & Sons, New York.

[0989] Oral Compositions

[0990] As a specific embodiment of an oral composition of a compound of this invention, 100 mg of one of the compounds described herein is formulated with sufficient finely divided lactose to provide a total amount of 580 to 590 mg to fill a size 0 hard gel capsule.

[0991] In-Vivo Models

[0992] A. Materials and Methods

[0993] 1. Forced Swim Test (FST)

[0994] The procedure used in this study was similar to that previously described (Porsolt, et al., 1978), except the water depth (30 cm in this procedure). The greater depth in this test prevented the rats from supporting themselves by touching the bottom of the cylinder with their feet. Swim sessions were conducted by placing rats in individual plexiglass cylinders (46 cm tall×20 cm in diameter) containing 23-25° C. water 30 cm deep (Porsolt, et al. used a depth of only 15 cm; also, see Detke, et al., 1995). Two swim tests were conducted always between 1200 and 1800 hours: an initial 15-min pretest followed 24 h later by a 5-minute test. Drug treatments were administered 60 minutes before the 5-minute test period. All other test sessions were conducted between 1300 to 1700 hours. Following all swim sessions, rats were removed from the cylinders, dried with paper towels and placed in a heated cage for 15 minutes and returned to their home cages. All test sessions were videotaped using a Panasonic color video camera and recorder for scoring later.

[0995] Animals

[0996] Male Sprague-Dawley rats (Taconic Farms, N.Y.) were used in all experiments. Rats were housed in pairs and maintained on a 12:12-h light-dark cycle. Rats were handled for 5 minutes each day for 5 days prior to behavioral testing.

[0997] Behavioral Scoring

[0998] The rat's behavior was rated at 5 second intervals during the 5 minute test as one of the following:

[0999] 1. Immobility—rat remained floating in the water without struggling and was only making those movements necessary to keep its head above water;

[1000] 2. Climbing—rat was making active movements with its forepaws in and out of the water, usually directed against the walls;

[1001] 3. Swimming—rat was making active swimming motions, more than necessary to merely maintain its head.above water, e.g. moving around in the cylinder; and

[1002] 4. Diving—entire body of the rat was submerged.

[1003] All of the behavior scoring was done by a single rater, who was blind to the treatment condition. The rater was also present in the room throughout the entire test period.

[1004] Drug Administration

[1005] Animals were randomly assigned to receive a single i.p. administration of Example 92 (1, 3, 10 or 30 mg/kg, dissolved in 100% DMSO), fluoxetine (10 mg/kg, dissolved in distilled water) or vehicle (equal mixture of DMSO and distilled water) 30 minutes before the start of the minute test period. All injections were given using 1 cc tuberculin syringe with 26⅜ gauge needles (Becton-Dickinson, VWR Scientific, Bridgeport, N.J.). The volume of injection was 1 ml/kg.

[1006] In another set of experiments, animals were randomly assigned to receive a single p.o. administration of one of the following treatments: Example 151 (1, 3 or 10mg/kg), fluoxetine (5 or 10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 60 minutes before the start of the 5 minute test period. The drugs were dissolved in 100% N,N-dimethylacetamide. All administrations were given using 1 cc tuberculin syringes, to which a 3 inch, curved, stainless steel gavage needle was attached. The volume of administration was 1 ml/kg.

[1007] In other sets of experiments, animals were randomly assigned to receive a single p.o. administration of one of the following treatments: Example 103 (3, 10 and 30 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 60 minutes before the start of the 5 minute test period; or Example 272 (3 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 24 hours before the start of the 5 minute test period; or Example 98 (3, 10 and 30 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 60 minutes before the start of the 5 minute test period; or Example 34 (0.3, 1, 3 and 10 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of a 100% solution of dimethylacetamide) 60 minutes before the start of the 5 minute test period; or Example 49 (3, 10 and 30 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 60 minutes before the start of the 5 minute test period; or Example 22 (3, 10 and 30 mg/kg), fluoxetine (10 mg/kg) or vehicle (1 ml/kg of 100% N,N-dimethylacetamide) 60 minutes before the start of the 5 minute test period. The compounds were dissolved in 100% N,N-dimethylacetamide. All administrations were given using 1 cc tuberculin syringes, to which a 3 inch, curved, stainless steel gavage needle was attached. The volume of administration was 1 ml/kg.

[1008] The effect of 5 or 10 mg/kg of fluoxetine was utilized in the FST as a positive control.

[1009] Data Analysis

[1010] The forced swim test data (immobility, swimming, climbing, diving) were subjected to a randomized, one-way ANOVA and post hoc tests conducted using the Student-Newman-Keuls test. The data were analyzed using the GBSTAT program, version 6.5 (Dynamics Microsystems, Inc., Silver Spring, Md., 1997). All data are presented as means ±S.E.M.

[1011] 2. Social Interaction Test (SIT)

[1012] Rats were allowed to acclimate to the animal care facility for 5 days and were housed singly for 5 days prior to testing. Animals were handled for 5 minutes per day. The design and procedure for the Social Interaction Test was carried out as previously described by Kennett, et al. (1997). On the test day, weight matched pairs of rats (±5%), unfamiliar to each other, were given identical treatments and returned to their home cages. Animals were randomly divided into 5 treatment groups, with 5 pairs per group, and were given one of the following i.p. treatments: Example 92 (10, 30 or 100 mg/kg), vehicle (1 ml/kg) or chlordiazepoxide (5 mg/kg). Dosing was 1 hour prior to testing. Rats were subsequently placed in a white perspex test box or arena (54×37×26 cm), whose floor was divided up into 24 equal squares, for 15 minutes. An air conditioner was used to generate background noise and to keep the room at approximately 74° F. All sessions were videotaped using a JVC camcorder (model GR-SZ1, Elmwood Park, N.J.) with either TDK (HG ultimate brand) or Sony 30 minute videocassettes. All sessions were conducted between 1:00-4:30 P.M. Active social interaction, defined as grooming, sniffing, biting, boxing, wrestling, following and crawling over or under, was scored using a stopwatch (Sportsline model no. 226, {fraction (1/100)} sec. discriminability). The number of episodes of rearing (animal completely raises up its body on its hind limbs), grooming (licking, biting, scratching of body), and face washing (i.e. hands are moved repeatedly over face), and number of squares crossed were scored. Passive social interaction (animals are lying beside or on top of each other) was not scored. All behaviors were assessed later by an observer who was blind as to the treatment of each pair. At the end.of each test, the box was thoroughly wiped with moistened paper towels.

[1013] Animals

[1014] Male albino Sprague-Dawley rats (Taconic Farms, N.Y.) were housed in pairs under a 12 hr light dark cycle (lights on at 0700 hrs.) with free access to food and water.

[1015] Drug Administration

[1016] Example 92 was dissolved in 100% DMSO (Sigma Chemical Co., St. Louis, Mo.). Chlordiazepoxide (purchased from Sigma Chemical Co., St. Louis, Mo.) was dissolved in double distilled water. The vehicle consisted of 50% DMSO (v/v). All drug solutions were made up 10 minutes prior to injection and the solutions were discarded.

[1017] Example 34 was dissolved in 5% lactic acid, v/v. The vehicle consisted of 100% dimethylacetamide (DMA) and this was used to make up all drug solutions. All drug solutions were made up fresh each day and any unused solutions were discarded at the end of the test day. The volume of drug solution administered was 1 ml/kg.

[1018] Data Analysis

[1019] The social interaction data (time interacting, rearing and squares crossed) were subjected to a randomized, one-way ANOVA and post hoc tests conducted using the Student-Newman-Keuls test. The data were subjected to a test of normality (Shapiro-Wilk test). The data were analyzed using the GBSTAT program, version 6.5 (Dynamics Microsystems, Inc., Silver Spring, Md., 1997). All data are presented as means ±S.E.M.

[1020] B. Results

[1021] 1. Forced Swim Test

[1022] A. The Effect Of Vehicle, Fluoxetine and Example 92 On Immobility, Climbing and Swimming In The Forced Swim Test

[1023] Immobility

[1024] Statistical analysis indicated that there was a significant drug effect [F(4,45)=12.1, p<0.0001] on immobility. Subsequent post hoc analysis revealed that a single injection of 10 mg/kg i.p. of fluoxetine significantly decreased immobility to 21.0±0.9 (Student-Newman-Keuls value was 36.5, p<0.01) compared to vehicle-treated controls (Table 5 and FIG. 1). In addition, a single injection of either 3 or 10 mg/kg i.p. of Example 92 significantly decreased immobility (24±1.1 & 24±0.8 counts at each dose, respectively) compared to vehicle-treated controls 30±1.2 (Student-Newman-Keuls values of 16.8 and 15.7, respectively) (Table 5 and FIG. 1). No significant effects on immobility were observed with Example 92 at 30 mg/kg i.p. (Table 5 and FIG. 1).

[1025] Climbing

[1026] The statistical analysis of the climbing counts indicated that there was a significant drug effect [F(4,45)=4.4, p=0.004]. Post hoc analysis indicated that a single injection of 10 mg/kg of fluoxetine did not significantly alter climbing counts compared to vehicle-treated animals (Table 5 and FIG. 2). In contrast, a single injection of 10 mg/kg of Example 92 produced a significant increase (16.8±0.6) in climbing counts (Student-Newman-Keuls value=11.6, p<0.01) compared to vehicle-treated animals (12±0.8). Example 92 dosed at 1, 3 & 30 mg/kg did not significantly alter climbing.

[1027] Swimming

[1028] The statistical analysis of the swimming data indicated that there was a significant drug effect [F(4,45)=6.6, p<0.0001] (Table 5 and FIG. 3). The post hoc test showed that a single injection of 10 mg/kg i.p. of fluoxetine produced a significant increase (25±1.2) in swimming counts over the vehicle treated animals, 18±1 (Student-Newman-Keuls value of 19.9, p<0.01). In contrast, a single injection of 1, 3 or 10 mg/kg i.p. of Example 92 did not significantly alter swimming counts 20±1.1, 21±0.9,& 18±0.9, respectively (Table 5 and FIG. 3). (However, at 30 mg/kg i.p. Example 92 significantly increased swim behavior in the rat, comparable to fluoxetine at 10 mg/kg i.p. (27±2.5 vs. 25±1.2, Table 5 and FIG. 3).

[1029] Diving

[1030] This behavior was rarely observed following a single injection of vehicle (0.1±0.1, one animal dove once), fluoxetine (0.1±0.1, one animal out of 10 dove once), 1 mg/kg of Example 92 (0.6±0.2; 5 animals had counts of 2, 1, 1, 1, and 1), 3 mg/kg of Example 92 (0.6±0.3; 3 animals had counts of 3, 2 and 1) or 10 mg/kg of Example 92 (0.5±0.5; note: only one animal at this dose showed diving behavior and the score was 5). At 30 mg/kg i.p. of Example 92 diving behavior was only observed in two animals (mean=0.2±0.2). Thus there was no significant drug effect on diving [F(4,45)=0.77, p=0.55].

[1031] The results of the Forced Swim Test indicate that using a modified version of the Lucki forced swim test, a single injection of 10 mg/kg i.p. of fluoxetine produced a significant decrease in immobility and an increase in swimming in male Sprague-Dawley rats. This is consistent with findings from previous studies using the Lucki version (Detke, et al., 1995; Kirby and Lucki, 1997; Lucki, 1997; Page, et al., 1999; Reneric and Lucki, 1998). In addition, the results obtained using fluoxetine are consistent with those using other SSRIs (Detke, et al., 1995). Thus, a modified version of the Lucki forced swim test can consistently detect the antidepressant-like action of SSRIs such as fluoxetine.

[1032] Interestingly, at doses of 3 and 10 mg/kg i.p., Example 92, significantly decreased immobility compared to vehicle-treated animals. The magnitude of the decrease was not significantly different than that of fluoxetine. Thus, based on past interpretations of the Forced Swim Test, our results suggest that Example 92 has antidepressant-like properties.

[1033] A single injection of either 1, 3 or 10 mg/kg i.p. of Example 92 did not significantly alter swimming behavior. This is in contrast to the results obtained with fluoxetine, which increased swimming at 10 mg/kg i.p. Previously, it has been reported that compounds which selectively block serotonin uptake significantly increase swimming but not climbing whereas selective NE uptake blockers significantly increase climbing but not swimming behavior (Reneric and Lucki, 1998). Thus, the present findings suggest that Example 92 exhibits a profile similar to NE and selective serotonin reuptake inhibitors (SSRIs) depending on the dose tested.

[1034] Finally, as previously reported by Lucki, diving behavior was rarely observed in vehicle or fluoxetine-treated animals (1 dive in one rat for each group). Example 92 at all doses tested did not produce a significant effect on diving behavior. It is possible that antidepressant drugs do not induce diving behavior.

[1035] In conclusion, compared to vehicle-treated animals, Example 92, at doses of 3 and 10 mg/kg, produced a significant decrease in immobility and a significant increase in climbing at the 10 mg/kg dose. At 30 mg/kg i.p. Example 92 produced a significant increase in swimming behavior comparable with that observed with the antidepressant fluoxetine, thus supporting the antidepressant-like profile of Example 92.

[1036] B. The effect of Example 151, fluoxetine, and vehicle on swimming, climbing, immobility, and diving in the forced swim test.

[1037] Immobility

[1038] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(5,46)=3.5, p=0.0095). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Fisher's LSD value of 2.9) compared to vehicle-treated animals (Table 5a). In contrast, a single p.o. administration of 5 mg/kg of fluoxetine did not significantly alter immobility compared to vehicle-treated animals.

[1039] A single p.o. administration of 1 mg/kg of Example 151 did not significantly alter immobility compared to vehicle-treated animals (Table 5a). In contrast, a sinale p.o. administration of either 3 or 10 mg/kg of Example 151 significantly decreased immobility compared to animals treated with vehicle (Fisher's LSD values of 2.8 and 2.6, respectively) or 5 mg/kg p.o. of fluoxetine (Fisher's LSD values of 2.6 and 2.4, respectively). There was no significant difference in the reduction in immobility between 10 mg/kg of fluoxetine and 3 and 10 mg/kg of Example 151.

[1040] Swimming

[1041] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(5,46)=5.5, p=0.0005). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming behavior compared to vehicle-treated animals (Student-Newman-Keuls value of 16.8 (Table 5a). In contrast, a single p.o. administration of 5 mg/kg of fluoxetine did not significantly alter swimming compared to vehicle-treated animals.

[1042] A single p.o. administration of either 1, 3 or 10 mg/kg of Example 151 significantly increased swimming (Student-Newman-Keuls values of 6.9, 14.8 and 13.4, respectively) compared to vehicle-treated animals. There was no significant.difference in the magnitude of the increase in swimming between the doses of Example 151. The 3 and 10 mg/kg doses of Example 151 produced a significantly greater increase in swimming compared to animals treated with 5 mg/kg p.o. of fluoxetine. There was no significant difference in the increase in swimming between animals treated with 10 mg/kg of fluoxetine and those treated with Example 151.

[1043] Climbing Behavior

[1044] Statistical analysis revealed that climbing was not significantly altered by a single p.o administration of 1, 3 or 10 mg/kg of Example 151 or 5 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(5,46)=0.81, p=0.55)(Table 5a).

[1045] Divine

[1046] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 1, 3 or 10 mg/kg of Example 151 or 5 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(5,46)=0.36, p=0.87)(Table 5a).

10TABLE 5aThe effect of a single p.o. administration of vehicle,1, 3 and 10 mg/kg of Example 151 and 5 and 10 mg/kgof fluoxetine on immobility, climbing, diving and swimmingin the forced swim test in male Sprague-Dawley rats.TreatmentImmobilityClimbingSwimmingDivingVehicle46 ± 1.82.7 ± 0.711.4 ± 1.20.4 ± 0.4 1 mg/kg EX15141 ± 2.02.3 ± 0.616.8 ± 1.4d0.2 ± 0.2 3 mg/kg EX15138 ± 2.0a2.4 ± 0.519.5 ± 1.5e0.3 ± 0.210 mg/kg EX15139 ± 1.8b2.2 ± 0.518.9 ± 1.5e0.3 ± 0.2 5 mg/kg Fluox45 ± 1.3c1.2 ± 0.413.9 ± 1.00.0 ± 0.010 mg/kg Fluox38 ± 2.3a2.0 ± 0.619.8 ± 1.8e0.6 ± 0.6Each value represents the mean ± S.E.M.

[1047] The results of this study indicate that a single p.o. administration of Example 151, at doses of 1,3 and 10 mg/kg, produces a significant increase in swimming behavior. There was no significant difference in the magnitude of the increase in swimming between the doses of Example 151, although the 1 mg/kg dose produced a lower increase. In contrast, only the 3 and 10 mg/kg doses of Example 151 significantly decreased immobility compared to vehicle-treated animals. Thus, it appears that a single p.o. administration of either 3 or 10 mg/kg, compared to 1 mg/kg of Example 151, produce a more robust antidepressant-like profile in the FST in male Sprague-Dawley rats. Our results also indicate that Example 151 produced changes in swimming and immobility that were not significantly different from that of 10 mg/kg p.o. of fluoxetine. This suggests that Example 151 produces behavioral effects similar to that of 10 mg/kg of fluoxetine in the FST.

[1048] A single p.o. administration of 5 mg/kg of fluoxetine did not significantly alter swimming, climbing, diving or immobility compared to vehicle treated animals. This finding, together with the data indicating that 10 mg/kg of fluoxetine produces a significant effect on swimming and immobility in the FST, suggest that the threshold dose of fluoxetine is greater than 5, but less than 10 mg/kg. This is consistent with ex vivo data indicating that a p.o. dose of 7 mg/kg of fluoxetine is required to inhibit 5-HT uptake in the CNS by 50% (Leonard, 1996).

[1049] In conclusion, the results of this study indicate that a single p.o. administration of Example 151 (particularly the 3 and 10 mg/kg doses) produces behavioral effects in the FST in rats that resemble those of antidepressants.

[1050] C. The Effect of a Single P.O. Administration of Example 103, Fluoxetine and Vehicle on Swimming, Immobility, Climbing and Diving in the Forced Swim Test

[1051] Immobility

[1052] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(4,40)=6.3, p=0.0005). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Student-Newman-Keuls value of 8.3) compared to vehicle-treated animals (Table 5b). The decrease in immobility produced by fluoxetine was significantly greater than that of either 3 or 10 mg/kg p.o. of Example 103 (Student-Newman-Keuls values of 9.1 and 6.1, respectively).

[1053] A single p.o. administration of either 3 or 10 mg/kg of Example 103 did not significantly alter immobility compared to vehicle-treated animals. However, the 30 mg/kg dose of Example 103 produced a significant decrease in immobility (Student-Newman-Keuls values of 13.9) compared to vehicle-treated animals. In addition, the decrease in immobility produced by 30 mg/kg of Example 103 was significantly greater than that of 3 and 10 mg/kg of Example 103 (Student-Newman-Keuls values of 14.4 and 10.6, respectively). There was no significant difference between fluoxetine and 30 mg/kg of Example 103 in the reduction of immobility.

[1054] Swimming

[1055] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(4,40)=9.2, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming behavior compared to animals treated with vehicle, 3 or 10 mg/kg p.o. of Example 103 (Student-Newman-Keuls values of 14.9, 15.3 and 11.6, respectively) (Table 5b).

[1056] A single p.o. administration of either 3 or 10 mg/kg of Example 103 did not significantly alter swimming behavior compared to vehicle-treated animals. A single p.o. administration of 30 mg/kg of Example 103 produced a significantly greater increase in swimming behavior compared to animals treated with either vehicle, 3 or 10 mg/kg of Example 103 (Student-Newman-Keuls values of 18, 18.6 and 14.5 respectively).

[1057] Climbing Behavior

[1058] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 3, 10 or 30 mg/kg of Example 103 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(4,40)=1.2, p=0.31)(Table 5b).

[1059] Diving

[1060] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 3, 10 or 30 mg/kg of Example 103 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(4,40)=1.1, p 0.36)(Table 5b).

11TABLE 5bThe effect of a single p.o. administration of vehicle,10 mg/kg of fluoxetine and 3, 10 or 30 mg/kg ofExample 103 on immobility, climbing, diving and swimmingin the forced swim test in male Sprague-Dawley rats.TreatmentImmobilityClimbingSwimmingDivingVehicle44 ± 1.72.9 ± 0.713.1 ± 1.20.4 ± 0.2 3 mg/kg EX10344 ± 2.72.8 ± 0.613.2 ± 1.90.5 ± 0.410 mg/kg EX10342 ± 2.23.5 ± 0.614.3 ± 1.60.4 ± 0.230 mg/kg EX10332 ± 1.8a4.8 ± 0.722.7 ± 1.1c1.1 ± 0.510 mg/kg Fluox34 ± 2.3b3.8 ± 0.821.8 ± 1.4c0.1 ± 0.1Each value represents the mean ± S.E.M.

[1061] The results of this study indicated that as previously reported, a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming and a significant decrease in immobility in male rats in the FST compared to vehicle-treated animals. The magnitude of these changes are similar to those reported of our past studies with 10 mg/kg p.o. of fluoxetine. In contrast, neither climbing nor diving behavior was significantly altered by a single p.o. administration of 10 mg/kg of fluoxetine.

[1062] A single p.o. administration of either 3 or 10 mg/kg of Example 103 did not significantly alter swimming, climbing, immobility or diving in male rats in the FST, indicating that at these doses using the p.o. route, Example 103 does not exhibit antidepressant-like action in the FST. In contrast, a single p.o. administration of 30 mg/kg of Example 103 produced a significant increase in swimming and a significant decrease in immobility compared to animals treated with vehicle or 10 mg/kg of Example 103. However, the 30 mg/kg p.o. dose of Example 103 did not significantly alter diving or climbing counts compared to vehicle-treated animals. The increase in swimming counts produced by 30 mg/kg p.o. of Example 103 was comparable to that for 10 mg/kg of fluoxetine.

[1063] In conclusion, a single p.o. administration of 30 mg/kg of Example 103 (one hour before the last swim test) increases swimming and decreases immobility counts in the FST, suggesting that Example 103 has antidepressant-like properties.

[1064] D. Effect Of A Single P.O. Administration Of Example 272, Fluoxetine And Vehicle On Swimming, Climbing, Immobility And Diving In The Forced Swim Test

[1065] Immobility

[1066] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(2,27)=5.2, p=0.0126). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine and 3 mg/kg of Example 272 significantly decreased immobility (Student-Newman-Keuls values of 5.4 and 9.8, respectively) compared to vehicle-treated animals (Table 5c). There was no significant difference between fluoxetine and 3 mg/kg of Example 272 in the reduction of immobility (Student-Newman-Keuls value of 0.53).

[1067] Swimming

[1068] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(2,27)=9.9, p<0.0007). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine and Example 272 produced a significant increase in swimming behavior compared to animals treated with vehicle (Student-Newman-Keuls values of 11.9 and 17.5, respectively) (Table 5c). There was no significant difference in the increase in swimming between 10 mg/kg of fluoxetine and 3 mg/kg of Example 272 (Student-Newman-Keuls value of 0.42)

[1069] Climbing Behavior

[1070] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of either 3 mg/kg of Example 272 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(2,27) 1.8, p=0.19) (Table 5c)

[1071] Diving

[1072] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 3 mg/kg of Example 272 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(2,27)=0.65, p=0.53)(Table 5c).

[1073] The finding of this study indicate that a single p.o. administration of 3 mg/kg of the compound Example 272 produced a significant increase in swimming and a significant decrease in immobility 24 hours after administration compared to vehicle-treated animals. However, the administration of Example 272 did not significantly alter climbing or diving compared to vehicle-treated animals. These results are similar to those of a single p.o. administration of 10 mg/kg of fluoxetine. Our finding suggest that a single p.o. administration of 3 mg/kg of Example 272 has the profile of an antidepressant-like in male Sprague-Dawley rats in the Lucki version of the FST.

[1074] E. Effect Of A Single P.O. Administration of Example 98, Fluoxetine And Vehicle On Swimming, Climbing, Immobility And Diving In The Forced Swim Test.

[1075] Immobility

[1076] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(4,43)=7.5, p=0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Student-Newman-Keuls value of 23.8) compared to vehicle-treated animals (Table 5d).

[1077] A single p.o. administration of 3, 10 or 30 mg/kg of Example 98 significantly decreased immobility compared to vehicle-treated animals (Student-Newman-Keuls values of 19.3, 9.7 and 13.7, respectively). There was no significant difference between fluoxetine and 3, 10 or 30 mg/kg of Example 98 in the magnitude of the reduction of immobility. There were no significant differences between the doses of Example 98 regarding the magnitude of the decrease in immobility.

[1078] Swimming

[1079] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(4,43)=11, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming behavior compared to vehicle-treated animals (Student-Newman-Keuls value of 35.1) (Table 5d).

[1080] A single p.o. administration of 3, 10 or 30 mg/kg of Example 98 significantly increased swimming compared to vehicle-treated animals (Student-Newman-Keuls values of 24.4, 14.7 and 25.1, respectively) (Table 5d). There was no significant difference between fluoxetine and 3, 10 or 30 mg/kg of Example 98 in the magnitude of the increase in swimming. There were no significant. differences between the doses of Example 98 regarding the magnitude of the increase in immobility.

[1081] Climbing Behavior

[1082] There was a significant treatment effect on climbing behavior (ANOVA, F(4,43)=2.8, p=0.04) (Table 5d). Post-hoc tests indicated that this was the result of the 3 mg/kg dose of Example 98 producing a significantly greater increase in climbing compared to 30 mg/kg of Example 98 (Table 5d; Student-Newman-Keuls value of 8.6). There was no significant difference in the number of climbing counts between animals treated with vehicle and Example 98.

[1083] Diving

[1084] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 3, 10 or 30 mg/kg of Example 98 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(4,43)=1.29, p=0.29)(Table 5d).

Experiments were conducted 1 hr. after the appropriate treatment. aSignificantly less than Vehicle, p < 0.01, ANOVA and Student-Newman-Keuls test. bSignificantly greater than 30 mg/kg of Example 98, p < 0.05, ANOVA and Student-Newman-Keuls test. cSignificantly greater than Vehicle, p < 0.01, ANOVA and Student-Newman-Keuls test.

[1085] The results of this study clearly indicate that in male Sprague-Dawley rats, a single p.o. administration of 3, 10 or 30 mg/kg of Example 98 produces a significant increase in swimming and a significant decrease in immobility compared to vehicle-treated animals in the FST. In addition, the Example 98 induced alterations were similar in magnitude to that of a single p.o. administration of 10 mg/kg p.o. of fluoxetine. However, neither fluoxetine nor Example 98 produced a significant alteration in climbing or diving compared to vehicle-treated animals.

[1086] In conclusion, these results indicate that a single p.o. administration of Example 98 produces a profile in the modified Lucki version of the FST resembling that of the clinically established antidepressant fluoxetine.

[1087] F. Effect Of A Single P.O. Administration Of Example 34, Fluoxetine And Vehicle On Swimming, Climbing Immobility And Diving In The Forced Swim Test.

[1088] Immobility

[1089] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(5,44)=18.1, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Student-Newman-Keuls value of 39.6) compared to vehicle-treated animals (Table 5e). Fluoxetine also produced a significantly greater decrease in immobility compared to the 0.3 and 10 mg/kg doses of Example 34 (Student-Newman-Keuls values of 15.3 and 29.8, respectively). There was no significant difference in the magnitude of the decrease in immobility between fluoxetine and the 1 and 3 mg/doses of Example 34.

[1090] A single p.o. administration of 0.3, 1 and 3 mg/kg of Example 34 significantly decreased immobility compared to vehicle-treated animals (Student-Newman-Keuls values of 7.03, 41.6 and 42.0, respectively)(Table 5e). However, a single p.o. administration of 10 mg/kg of Example 34 did not significantly decrease in immobility compared to vehicle-treated animals. The magnitude of the decrease in immobility produced by 1 and 3 mg/kg doses of Example 34 was significantly greater than that for the 0.3 (Student-Newman-Keuls values of 14.5 and 15.3) and 10 mg/kg (Student-Newman-Keuls of 30.6 and 31.3, respectively) doses of Example 34 (Student-Newman-Keuls of 21.3 and 10.8, respectively).

[1091] Swimming

[1092] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(5,44)=33.0, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming compared to animals treated with vehicle, 0.3 or 10 mg/kg of Example 34 (Student-Newman-Keuls values of 73.7, 30.0 and 53.9, respectively) (Table 5e). There was no significant difference in swimming behavior between fluoxetine and the 1 and 3 mg/kg p.o. of Example 34.

[1093] A single p.o. administration of either 0.3, 1 or 3 mg/kg of Example 34 produced a significant increase in swimming behavior compared to vehicle-treated animals (Student-Newman-Keuls values of 12.1, 72.1 and 80.3, respectively) (Table 5e). In addition, the magnitude of the increase in swimming was greater for the 1 and 3 mg/kg doses (Student-Newman-Keuls values of 50.4 and 57.9, respectively) compared to 0.3 mg/kg of Example 34.

[1094] Climbing Behavior

[1095] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(5,44)=3.2., p=0.014) (Table 5e). Post hoc analyses revealed that a single p.o. administration of 1 mg/kg of Example 34 produced a significant increase in climbing compared to vehicle-treated animals (Student-Newman-Keuls value of 9.2) (Table 5e)

[1096] Diving

[1097] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 0.3, 1, 3 or to mg/kg of Example 34 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(5,44)=0.75, p=0.59)(Table 5e).

[1098] The results of this study indicate that a single p.o. administration (one hour before the final swim test) of either 0.3, 1 or 3 mg/kg of Example 34 produced a significant increase in swimming and a significant decrease in immobility compared to vehicle-treated animals. However, a single p.o. administration of 10 mg/kg of Example 34 did not significantly alter swimming or climbing compared to vehicle-treated animals. Currently, the explanation for the lack of effect of 10 mg/kg p.o. of Example 34 is unknown. The 1 mg/kg dose of Example 34 produced a significant increase in climbing compared to vehicle-treated animals. The magnitude of the alterations in swimming and immobility produced by 1 and 3 mg/kg p.o. of Example 34 was significantly greater than that for the 0.3 and 10 mg/kg doses of Example 34. Finally, none of the doses of Example 34 significantly altered diving behavior compared to vehicle-treated controls.

[1099] As previously reported, a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming and a significant decrease in immobility compared to vehicle-treated controls. The effect of fluoxetine on swimming and immobility was similar to that for the 1 and 3 mg/kg doses of Example 34 but was significantly greater than that of 0.3 and 10 mg/kg of Example 34. A single p.o. administration of 10 mg/kg of fluoxetine did not significantly alter climbing or diving behavior compared to vehicle-treated controls.

[1100] In conclusion, these results indicate that a single p.o. administration of 0.3, 1 or 3 mg/kg Example 34 produces an effect in the FST that resembles that of antidepressants in male Sprague-Dawley rats.

[1101] G. Effect Of A Single P.O. Administration Of Example 49, Fluoxetine And Vehicle On Swimming, Climbing, Immobility And Diving In The Forced Swim Test.

[1102] Immobility

[1103] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(4,41)=6.5, p=0.0004). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Student-Newman-Keuls value of 15.6) compared to vehicle-treated animals (Table 5f).

[1104] A single p.o. administration of either 3or 10 mg/kg of Example 49 did not significantly alter immobility compared to vehicle-treated animals. However, the 30 mg/kg dose of Example 49 produced a significant decrease in immobility (Student-Newman-Keuls values of 8.0) compared to vehicle-treated animals. In addition, the decrease in immobility produced by either fluoxetine or 30 mg/kg of Example 49 was significantly greater than that of the 10 mg/kg dose of Example 49. There was no significant difference between fluoxetine and 30 mg/kg of Example 49 in the reduction of immobility.

[1105] Swimming

[1106] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(4,41)=16.2, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming behavior compared to animals treated with vehicle, 3, 10 or 30 mg/kg p.o. of Example 49 (Student-Newman-Keuls values of 42.7, 20.9, 47.5 and 8.4, respectively) (Table 5f).

[1107] A single p.o. administration of either 3 or 10 mg/kg of Example 49 did not significantly alter swimming behavior compared to vehicle-treated animals. A single p.o. administration of 30 mg/kg of Example 49 produced a significantly greater increase in swimming behavior compared to animals treated with vehicle, 3 or 10 mg/kg of Example 49 (Student-Newman-Keuls values of 14 and 16.9, respectively).

[1108] Climbing Behavior

[1109] There was a significant treatment effect on climbing behavior (ANOVA, F(4,42)=5.9, p=0.007). Post hoc tests indicated that this was the results of the vehicle, 3, 10 and 30 mg/kg doses of Example 49 producing a significantly greater increase in climbing counts compared to fluoxetine-treated animals (Table 5f; Student-Newman-Keuls values of 7.9, 18.1, 14.05 and 12.9, respectively). There was no significant difference in the number of climbing counts between animals treated with vehicle and Example 49.

[1110] Diving

[1111] Statistical analysis revealed that diving was not significantly altered by a single p.o. administration of 3, 10 or 30 mg/kg of Example 49 or 10 mg/kg of fluoxet-ine compared to vehicle-treated animals (ANOVA, F(4,41)=1.06, p=0.38)(Table 5f).

Experiments were conducted 1 hr. after the appropriate treatment. aSignificantly less than Vehicle and 10 mg/kg of Example 49 p < 0.05, ANOVA and Student-Newman-Keuls test. bSignificantly less than Vehicle and 10 mg/kg of Example 49, p < 0.01, ANOVA and Student-Newman-Keuls test. cSignificantly less than all other treatment groups, p < 0.01, ANOVA and Student-Newman-Keuls test. dSignificantly greater than vehicle and 10 mg/kg of Example 49, p < 0.01, ANOVA and Student-Newman-Keuls test. eSignificantly greater than all other treatment groups, p < 0.01, ANOVA and Student-Newman-Keuls test.

[1112] The results of this study indicated that as previously reported, a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming and a significant decrease in immobility in male rats in the FST compared to vehicle-treated animals. The magnitude of these changes are similar to those reported of our past studies with 10 mg/kg p.o. of fluoxetine. In contrast, climbing behavior was significantly decreased by a single p.o. administration of 10 mg/kg of fluoxetine compared to all other treatment groups. However, this could be related to the fact that fluoxetine has a much greater effect on swimming than climbing and it is likely that fluoxetine is not producing climbing as opposed to actually decreasing climbing. Finally, fluoxetine, as previously reported, does not significantly alter diving compared to vehicle-treated behavior.

[1113] A single p.o. administration of either 3 or 10 mg/kg of Example 49 did not significantly alter swimming, climbing, immobility or diving in male rats in the FST, indicating that at these doses using the p.o. route, Example 49 does not exhibit antidepressant-like action in the FST. In contrast, a single p.o. administration of 30 mg/kg of Example 49 produced a significant increase in swimming and a significant decrease in immobility compared to animals treated with vehicle, or 3 and 10 mg/kg of Example 49. However, the 30 mg/kg p.o. dose of Example 49 did not significantly alter diving or climbing counts compared to vehicle-treated animals. The increase in swimming counts produced by 30 mg/kg p.o. of Example 49 was comparable to that of 10 mg/kg of fluoxetine, although Example 49 was less effective than fluoxetine in reducing immobility.

[1114] In conclusion, a single p.o. administration of 30 mg/kg of Example 49 (one hour before the last swim test) increases swimming and decreases immobility counts in the FST, suggesting that Example 49 may have antidepressant-like properties in this model.

[1115] H. Effect Of A Single P.O. Administration Of Example 22, Fluoxetine And Vehicle On Swimming, Climbing, Immobility And Diving In The Forced Swim Test

[1116] Immobility

[1117] Statistical analysis indicated a significant effect of treatment on immobility (ANOVA, F(4,44)=20.2, p<0.0001). Post hoc analyses revealed that a single p.o. administration of 10 mg/kg of fluoxetine significantly decreased immobility (Student-Newman-Keuls value of 20.1) compared to vehicle-treated animals (Table 5g).

[1118] A single p.o. administration of 10 or 30 mg/kg doses of Example 22 produced a significant decrease in immobility compared to vehicle-treated animals (Student-Newman-Keuls values of 12.2 and 55.0, respectively). In addition, the decrease in immobility produced the either fluoxetine or the 10 and 30 mg/kg doses of Example 22 (Student-Newman-Keuls values of 21.2, 13.0 and 56.8, respectively) was significantly greater than that of the 3 mg/kg dose of Example 22. The decrease in immobility produced by 30 mg/kg i.p. of Example 22 was significantly greater than that of the 10 mg/kg dose (Student-Newman-Keuls value 16.2). In addition, the magnitude of the decrease in immobility produced by 30 mg/kg of Example 22 was significantly greater than that of fluoxetine (Student-Newman-Keuls value of 9.3).

[1119] Swimming

[1120] Statistical analysis indicated a significant treatment effect on swimming behavior (ANOVA, F(4,44)=35.00, p<0.0001). Post hoc analyses revealed that a single i.p. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming compared to animals treated with vehicle, 3 or 10 mg/kg of Example 22 (Student-Newman-Keuls values of 49.6, 51.3 and 5.8, respectively) (Table 5g).

[1121] A single p.o. administration of 3 mg/kg did not significant alter swimming behavior compared to vehicle-treated animals (Table 5g). However, a single p.o. administration of 30 mg/kg of Example 22 produced a significantly greater increase in swimming behavior compared to animals treated with vehicle, 3 or 10 mg/kg of Example 22 and fluoxetine (Student-Newman-Keuls values of 85.9, 88.1, 22.7 and 5.84, respectively).

[1122] Climbing Behavior

[1123] There was a significant treatment effect on climbing behavior (ANOVA, F(4,44)=4.1, D=0.0066). Post hoc tests indicated that a single p.o. administration of 30 mg/kg dose of Example 22 produced a significant increase in climbing compared to animals treated with vehicle, 3 or 10 mg/ka of Example 22 and fluoxetine (Student-Newman-Keuls values of 10.5, 11.1, 5.8 and 11.8, respectively).

[1124] Diving

[1125] Statistical analysis revealed that diving was not significantly altered by a single i.p. administration of 3, 10 or 30 mg/kg of Example 22 or 10 mg/kg of fluoxetine compared to vehicle-treated animals (ANOVA, F(4,44)=0.58, p=0.68)(Table 5g).

[1126] The results of this study indicated that as previously reported, a single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming and a significant decrease in immobility in male Sprague-Dawley rats in the FST compared to vehicle-treated animals. The magnitude of these changes are similar to those reported of our past studies with. 10 mg/kg p.o. of fluoxetine. In contrast, neither climbing nor diving behavior was significantly altered by a single i.p. administration of 10 mg/kg of fluoxetine.

[1127] A single p.o. administration of 3 mg/kg of Example 22 did not significantly alter swimming in male rats in the FST. In contrast, a single p.o. administration of 10 or 30 mg/kg of Example 22 produced a significant increase in swimming and a significant decrease in immobility compared to animals treated with vehicle or 3 mg/kg of Example 22. In addition, the magnitude of the increase in swimming behavior produced by 30 mg/kg p.o. of Example 22 was significantly greater than that of 10 mg/kg of Example 22 and 10 mg/kg of fluoxetine. The rank order of the treatments for increasing swimming is: 30 mg/kg Example 22>fluoxetine>10 mg/kg Example 22>3 mg/kg Example 22

[1128] Climbing behavior was significantly greater in animals treated with 30 mg/kg p.o. of Example 22 compared to animals treated p.o. with either vehicle, 3 or 10 mg/kg of Example 22 or 10 mg/kg of fluoxetine. None of the other treatments besides 30 mg/kg of Example 22 significantly altered climbing behavior compared to vehicle-treated animals. The rank order of the treatments for increasing climbing is: 30 mg/kg Example 22>>3 Mg/kg Example 22=10 mg/kg Example 22=fluoxetine.

[1129] A single p.o. administration of 3 mg/kg of Example 22 did not significantly alter swimming compared to vehicle-treated animals. However, the 10 and 30 mg/kg doses produced a significantly greater decrease in immobility compared to vehicle-treated animals, with the effect at 30 mg/kg being greater then that of 10 mg/kg. Furthermore, 30 mg/kg p.o. of Example 22 produced a significantly greater decrease in immobility than 10 mg/kg p.o. of fluoxetine. The rank order of the treatments for decreasing immobility is 30 mg/kg Example 22>10 mg/kg Example 22=fluoxetine>3 mg/kg Example 22.

[1130] In conclusion, a single p.o. administration of 10 or 30 mg/kg of Example 22 significantly increases swimming and significantly decreases immobility in vehicle-treated male Sprague-Dawley rats. This suggests that at these doses, Example 22 has antidepressant-like properties.

[1131] I. Effect Of A Single P.O. Administration Of Example 95, Fluoxetine And Vehicle On Swimming, Climbing, Immobility And Diving In The Forced Swim Test

[1132] Statistical analysis indicated that a single p.o. administration of 10 or 30 mg/kg Example 95 significantly increased rat immobility and significantly decreased swim behavior in the rat forced swim test at both doses (Table 5h, p<0.01, ANOVA and Student-Newman-Keuls, respectively).

17TABLE 5hThe effect of a single p.o. administration of vehicle,10 mg/kg of fluoxetine and 3, 10 or 30 mg/kg of Example 95 onimmobility, climbing, diving and swimming i the forced swim test inmale Sprague-Dawley rats.TreatmentImmobilityClimbingSwimmingDivingVehicle42 ± 1.72.3 ± 0.514.7 ± 1.00.1 ± 0.1 3 mg/kg40 ± 3.32.6 ± 0.817.1 ± 2.50.0 ± 0.0EX9510 mg/kg52 ± 1.2a1.3 ± 0.5 6.9 ± 0.9b0.1 ± 0.1EX9530 mg/kg54 ± 0.9a1.0 ± 0.3 4.8 ± 0.7b0.0 ± 0.0EX9510 mg/kg38 ± 2.21.9 ± 0.620.0 ± 1.5c0.1 ± 0.1FluoxEach value represents the mean ± S.E.M.

[1133] A single p.o. administration of 10 mg/kg of fluoxetine produced a significant increase in swimming behavior compared to vehicle-treated animals. In addition, fluoxetine significantly decreased immobility compared to vehicle-treated animals. A single p.o. administration of 3 mg/kg of Example 95 did not significantly alter swimming, climbing, immobility or diving behavior compared to vehicle-treated animals. In contrast, a single p.o. administration of either 10 or 30 mg/kg of Example 95 produced a significant increase in immobility and a significant decrease in swimming behavior compared to vehicle-treated animals. There was no significant difference in the magnitude or change in swimming and immobility between the 10 and 30 mg/kg doses of Example 95.

[1134] These data indicate that at a doses of 10 and 30 mg/kg p.o., Example 95 produced effects opposite of that seen with antidepressants in the rat forced swim test, suggesting that Example 95 does not produce antidepressant-like actions in the forced swim test in male Sprague-Dawley rats.

[1135] 2. Social Interaction Test

[1136] A. The Effect Of Example 92 And Chlordiazepoxide On Behavior In The Rat Social Interaction Test

[1137] A single i.p. administration of either 10 or 30 mg/kg of Example 92 significantly increased social interaction (Table 6 and FIG. 4), as did the benzodiazepine anxiolytic, chlordiazepoxide (Student-Newman-Keuls value of 31.3) compared to vehicle-treated animals [ANOVA, F(4,45)=10.3, p<0.0001; Student-Newman-Keuls values for the 10 and 30 mg/kg doses were 8.61 and 19.55, respectively]. However, the 100 mg/kg i.p. dose of Example 92 did not significantly alter social interaction time compared to vehicle-treated animals (Table. 6, and FIG. 4). The degree of social interaction was greater in the chlordiazepoxide-treated animals compared to those that received either the 10 or 30 mg/kg doses of Example 92.

[1138] B. The Effect Of Example 92 And Chlordiazepoxide On Rearing Behavior, Locomotor Activity And Grooming In The Rat Social Interaction Test

[1139] The administration of 10 and 30 mg/kg, but not 100 mg/kg of Example 92, significantly increased rearing behavior compared to either vehicle or chlordiazepoxide [ANOVA, F(4,45) 2.6, p=0.046; See Table 13]. In addition, the number of rearings at the 10 mg/kg dose of Example 92 was significantly greater than that produced by chlordiazepoxide (Table 13).

[1140] The administration of either Example 92 or chlordiazepoxide did not significantly alter the number of grooming bouts compared to vehicle-treated animals [F(4,45)=0.67, p=0.62].

[1141] A single injection of either 10 or 30 mg/kg i.p. of Example 92 or 5 mg/kg i.p. of chlordiazepoxide did not significantly alter the number of squares crossed (Table 13). However, the number of squares crossed following the 100 mg/kg dose of Example 92 was significantly lower than animals treated with either vehicle, 10 mg/kp i.p. of Example 92, 30 mg/kg i.p. of Example 92 or 5 mg/kg i.e. of chlordiazepoxide. [ANOVA, F(4,43)=6.94, p=0.0002].

[1142] At doses of 10 and 30 mg/kg i.p., Example 92 produced a significant increase in social interaction time in male rats compared to vehicle-treated animals. Also, the anxiolytic agent (5 mg/kg i.p. chlordiazepoxide) produced a significant increase in social interaction time compared to vehicle-treated animals. The response produced by the 30 mg/kg dose of Example 92 was comparable to that of the positive control, chlordiazepoxide. The 30 mg/kg dose of Example 92 produced a significant increase in rearing compared to vehicle- and chlordiazepoxide-treated animals. Previously, it has been shown that in the Social Interaction Test, psychostimulants such as amphetamine and caffeine, increase social interaction and locomotor activity, whereas anxiolytics increase social interaction time. (File, 1985; File and Hyde, 1979; Guy and Gardner, 1985). Consistent with an increase in social interaction, Example 92 increased rearing behavior. However, it did not produce an increase in horizontal locomotor activity or grooming bouts. In addition, Example 92 did not elicit stereotypes or produce aggressive behaviors. In fact, locomotor activity as measured by squares crossed was significantly reduced at the 100 mg/kg i.p. dose of Example 92 compared to vehicle-treated animals. This decrease in locomotor activity did not appear to be accompanied by ataxia or sedation. Thus, it is unlikely that Example 92 is producing a non-specific effect on social interaction through motor stimulation. In order to justify this claim, in another study (not reported), the effect of Example 92 was dosed to familiar cage mates in the social interaction test and no significant increase in interaction in this variation of the Social Interaction Test was observed. In this test, the anxiogenic stimulus of a novel partner is removed and therefore only locomotor activity and normal behavior are observed (Guy and Gardner, 1985). In conclusion, the results of this study indicate that Example 92, at doses of 10 and 30 mg/kg i.p., significantly increases social interaction time without producing an increase in horizontal locomotor activity or grooming bouts. Furthermore, the effect produced by the 30 mg/kg of Example 92 was comparable to that observed for 5 mg/kg of chlordiazepoxide, the active control. No increase in social interaction was observed at the 100 mg/kg dose of Example 92. However, a decrease in the number of squares crossed was observed. In summary, Example 92 has the profile of an anxiolytic-like drug in the Social Interaction Test.

[1143] C. The Effect Of A Single P.O. Administration Of Example 34, Vehicle And Chlordiazepoxide On The Duration Of Social Interaction In The Rat Social Interaction Test.

[1144] There was a significant treatment effect on the duration of social interaction (ANOVA, F(5,40)=11.8, p<0.001). Subsequent post hoc analyses indicated that a single p.o. administration of either 0.03, 0.1, 0.3 and 1 mg/kg of Example 34 (Student-Newman-Keuls test values of 8.0, 10.6, 4.3 and 13.2, respectively) significantly increased social interaction, as did chlordiazepoxide (Student-Newman-Keuls value of 57.1), compare to vehicle-treated animals (Table 6a). The duration of social interaction produced by chlordiazepoxide was significantly greater than that of 0.03, 0.1, 0.3 and 1 mg/kg p.o. of Example 34 (Student-Newman-Keuls values of 19.6, 18.6, 26.2 and 17.6, respectively). There was no significant difference in the duration of social interaction between the various doses of Example 34 (Table 6a).

[1145] D. The Effect Of A Single P.O. Administration Of Example 34, Vehicle And Chlordiaz Poxide On Rearing Behavior, Locomotor Activity And Grooming In The Social Interaction Test.

[1146] Statistical analysis indicated a significant effect of treatment on rearing behavior (ANOVA, F(5,40)=3.5, p=0.01; Table 14). Post hoc analyses revealed that the the number of rears following 0.3 mg/kg of Example 34 was significantly lower than that of 0.1 and 1 mg/kg p.o. of Example 34 (Student-Newman-Keuls values of 8.8 amd 9.4, respectively).

[1147] Statistical analysis indicated a significant effect of treatment on number of squares crossed (F(5,40)=2.9, p=0.03). Post hoc analyses indicated that a single p.o. administration of 0.3 mgxkg of Example 34 produced a significantly greater effect on the number of squares crossed compared to vehicle-treated animals (Student-Newman-Keuls values of 10.4).

[1148] Statistical analysis indicated a significant effect of treatment on grooming behavior (F(5,40)=4.3, p=0.004). Post hoc analyses indicated that the number of grooming episodes was significantly lower in the 0.03 mg/kg group compared to animals treated with 0.1, 0.3 or 1 mg/kg p.o. of Example 34 (Student-Newman-Keuls values of 11, 8 and 9.7, respectively (Table 14). In additon, the number of grooming episodes was significantly greater in animals treated with 0.1 mg/kg p.o. of Example 34 compared to those treated with vehicle (Table 14).

[1149] One of the main findings of this study was that in paired, unfamiliar male Sprague-Dawley rats, a single p.o. administration of either 0.03, 0.1, 0.3 or 1 mg/kg p.o. of Example 34 produced a significant increase (2-2.6 fold) in the duration of social interaction compared to animals treated with vehicle. In addition, there was no significant difference in the magnitude of increase in social interaction between the various doses of Example 34, i.e. there was no dose-response relationship. As previously reported, a single p.o. administration of 5 mg/kg of chlordiazepoxide produced a significant increase in the duration of social interaction compared to vehicle-treated animals.

[1150] Rearing behavior was not significantly altered by any of the doses of Example 34 or by chlordiazepoxide compared to vehicle-treated animals, although there were differences between the doses of Example 34. The number of squares crossed was significantly greater following a single p.o. administration of 1 mg/kg of Example 34 compared to vehicle-treated animals, whereas there were no significant differences between the other doses of Example 34 and vehicle. Thus, overall, Example 34 does not significantly alter locomotor activity, suggesting that it does not produce locomotor activation or stimulation.

[1151] Grooming behavior following a single p.o. administration tended to be greater after 0.1, 0.3 and 1 mg/kg of Example 34 compared to animals that had received vehicle, although this was only statistically significant for the 0.1 mg/kg dose. Furthermore, the number of grooming episodes was significantly lower after a single p.o. administration of 0.03 mg/kg of Example 34 compared to 0.1, 0.3 and 1 mg/kg of Example 34.

[1152] In conclusion, the above results suggest that a single p.o. administration of 0.03, 0.1, 0.3 or 1 mg/kg of Example 34 produces an anxiolytic-like action in the social interaction test in male Sprague-Dawley rats.

[1153] Binding Properties of ComPounds at Cloned Receptors

[1154] A. Materials and Methods

[1155] The binding properties of the compounds of the present invention were evaluated at one or more cloned receptors or native, tissue-derived transporters, using protocols described below.

[1156] Cell Culture

[1157] COS-7 cells were grown on 150 mm plates in D-MEM with supplements (Dulbecco's Modified Eagle Medium with 10% bovine calf serum, 4 mM glutamine, 100 units/ml penicillin, 100 μg/ml streptomycin) at 37° C. with 5% CO2. Stock plates of COS-7 cells were trypsinized and split 1:6 every 3-4 days. Human embryonic kidney 293 cells were grown on 150 mm plates in D-MEM with supplements (minimal essential medium) with Hanks' salts and supplements (Dulbecco's Modified Eagle Medium with 10% bovine calf serum, 4 mM glutamine, 100 units/ml penicillin, 100 μg/ml streptomycin) at 37° C. with 5% CO2. Stock plates of 293 cells were trypsinized and split 1:6 every 3-4 days. Mouse fibroblast LM(tk-) cells were grown on 150 mm plates in D-MEM with supplements (Dulbecco's Modified Eagle Medium with 10% bovine calf serum, 4 mM glutamine, 100 units/mL penicillin, 100 μg/mL streptomycin) at 37° C. with 5% CO2. Stock plates of LM(tk-) cells were trypsinized and split 1:10 every 3-4 days. Chinese Hamster Ovary (CHO) cells were grown on 150 mm plates in HAM's F12 medium with (HAM's F-12 with 10% bovine calf serum, 4 mM glutamine, 100 units/mL penicillin, 100 μg/mL streptomycin) at 37° C. with 5% CO2. Stock plates of CHO cells were trypsinized and split 1:8 every 3-4 days.

[1158] LM(tk-) cells were stably transfected with the human GAL1 or GAL3 receptor. CHO cells were stably transfected with the human GAL2 receptor.

[1159] Stable Transfection

[1160] cDNAs for the human and rat GAL1, and human and rat GAL3 receptors were transfected with a G-418 resistant gene into the mouse fibroblast LM(tk-) cell line by a calcium phosphate transfection method (Cullen, 1967). Stably transfected cells were selected with G-418. Human and rat GAL2 receptors were similarly transfected into CHO cells.

[1161] Membrane Harvest

[1162] Membranes were harvested from stably transfected LM(tk-) cells. Adherent cells were washed twice in ice-cold phosphate buffered saline (138 mM NaCl, 8.1 mM Na2HPO4, 2.5 mM KCl, 1.2 mM KH2PO4, 0.9 mM CaCl2, 0.5 mM MgCl2, pH 7.4) and lysed by sonication in ice-cold sonication buffer (20 mM Tris-HCl, 5 mM EDTA, pH 7.7). Large particles and debris were cleared by low speed centrifugation (200×g, 5 min, 4° C.). Membranes were collected from the supernatant fraction by centrifugation (32,000×g, 18 min, 4° C.), washed with ice-cold hypotonic buffer, and collected again by centrifugation (32,000×g, 18 min, 4° C.). The final membrane pellet was resuspended by sonication into a small volume of ice-cold binding buffer (−1 ml for every 5 plates: 10 mM NaCl, 20 mM HEPES, 0.22 mM KH2PO4, 1.26 mM CaCl2, 0.81 mM MgSO4, pH 7.4). Protein concentration was measured by the Bradford method (Bradford, 1976) using Bio-Rad Reagent, with bovine serum albumin as a standard. Membranes were held on ice for up to one hour and used fresh, or flash frozen and stored in liquid nitrogen. Membranes were prepared similarly from CHO cells.

[1163] As described in the Background of the Invention, compounds that block the effects of galanin on the GAL3 receptor subtype can potentially be used for the treatment of depression and anxiety. Biogenic amine transmitter molecules that mediate neuronal signals are currently known in the art and include among others serotonin (5HT), norepinephrine (NE), and dopamine (DA). Recent advances in the molecular studies of the mechanisms for these transmitter molecules, together with the characterization of their pharmacological properties, has enabled the identification of numerous potential targets for therapeutic intervention. Inhibitors of the 5HT, NE and DA transporter systems, and inhibitors of the enzyme, monoamine oxidase, have been widely studied and are known to enhance the action of biogenic amine neurotransmitters. The resultant clinically effective antidepressant drugs are known today as TCAs, SSRIs and MAOIs. (Tatsumi et al., 1997; Iversen, 2000).

[1164] In the case of galanin, the evidence presented in this invention suggests that GPCR-targeted molecules that bind to and antagonize the GAL3 receptor may be used for the treatment of depression and/or anxiety disorders. Another approach could involve the administration of an antagonist of the GAL3 receptor, such as those described herein, which also possesses 5HT4 receptor antagonist properties (Kennett et al., 1997). A further approach could involve the administration of a GAL3 antagonist, such as those described herein, which also possesses 5HT1A receptor binding properties (Razani et al., 1997). However, in any case the GAL3 antagonist(s) should be free of activity at the human GALL receptor and the 5HT, NE and DA transporters. Furthermore, the GAL3 antagonist(s) should not inhibit the enzymatic activity of monoamine oxidase A (MAOA) or monoamine oxidase B (MAOB) present in the brain (i.e. central MAO). The design of such compounds can be optimized by determining their binding affinity at the recombinant GAL3, GAL1, 5HT4, and 5HT1A receptors; and the native 5HT, NE and DA transporters. The design of such compounds can be further optimized by determining their interaction with central MAOA and central MAOB.

[1165] Additionally, the GAL3 antagonist(s) would optimally not bind at the following receptors due to possible side effects: human GAL2; human H1 histamine; human α1A adrenergic, human α1B adrenergic, human α1D adrenergic, human α2A adrenergic, human α2B adrenergic, and human α2C adrenergic; human dopamine D1, D2, D3, D4, and D5; and the human 5HT1B, human 5HT1D, human 5HT1E, human 5HT1F, human 5HT2A, rat 5HT2C, human 5HT6, and human 5HT7 receptors.

[1166] Radioligand Binding Assays and Enzymatic Assays

[1167] The methods to obtain the cDNA of the receptors, express said receptors in heterologous systems, and carry out assays to determine binding affinity are described as follows.

[1168] Galanin Receptors: Binding assays were performed according to the following published methods: human GAL3 (PCT International Publication No. WO 98/15570), human GAL1 (PCT International Publication No. WO 95/2260) human GAL2 (PCT International Publication No. WO 97/26853).

[1169] Human 5HT1B, 5HT1D, 5HT1E, 5HT1F, and 5HT7 ReceDtors: The cell lysates of LM(tk-) clonal cell line stably transfected with the genes encoding each of these 5HT receptor-subtypes were prepared as described above. Cell membranes were suspended in 50 mM Tris-HCl buffer (pH 7.4 at 37° C.) containing 10 mM MgCl2, 0.2 mM EDTA, 10 M pargyline, and 0.1% ascorbate. The affinities of compounds were determined in equilibrium competition binding assays by incubation for 30 minutes at 37° C. in the presence of 5 nM [3H]-serotonin. Nonspecific binding was determined in the presence of 10 μM serotonin. The bound radioligand was separated by filtration through GF/B filters using a cell harvester.

[1170] Human 5HT2; Receptor: The coding sequence of the human 5HT2A receptor was obtained from a human brain cortex cDNA library, and cloned into the cloning site of pCEXV-3 eukaryotic expression vector. This construct was transfected into COS-7 cells by the DEAE-dextran method (Cullen, 1987). Cells were harvested after 72 hours and lysed by sonication in 5 mM Tris-HCl, 5 mM EDTA, pH 7.5. The cell lysates were subjected to centrifugation at 1000 rpm for 5 minutes at 4° C., and the supernatant was subjected to centrifugation at 30,000×g for 20 minutes at 4° C. The pellet was suspended in 50 mM Tris-HCl buffer (pH 7.7 at room temperature) containing 10 mM MgSO4, 0.5 mM EDTA, and 0.1% ascorbate. The affinity of compounds at 5HT2A receptors were determined in equilibrium competition binding assays using [3H]ketanserin (1 nM). Nonspecific binding was defined by the addition of 10 μM mianserin. The bound radioligand was separated by filtration through GF/B filters using a cell harvester.

[1171] 5-HT1r Receptor: The cDNA corresponding to the 5-HT1A receptor open reading frames and variable non-coding 5′- and 3′-regions, was cloned into the eukaryotic expression vector pCEXV-3. These constructs were transfected transiently into COS-7 cells by the DEAE-dextran method (Cullen, 1987), and harvested after 72 hours. Radioligand binding assays were performed as described above for the 5-HT2A receptor, except that 3H-8-OH-DPAT was used as the radioligand and nonspecific binding was determined by the addition of 10 μM mianserin.

[1172] Other 5-HT ReceDtors: Other serotonin receptor binding assays were performed according to published methods: rat 5HT2c receptor (Julius et al., 1988); and 5-HT6 (Monsma, et al., 1993). The binding assays using the 5-HT4 receptor were performed according to the procedures described in U.S. Pat. No. 5,766,879, the disclosure of which is hereby incorporated by reference in its entirety into this application.

[1173] Other receptors: Cell membranes expressing human dopamine D1, D2, D4 and rat D3 receptors were purchased through BioSignal, Inc. (Montreal, Canada). Binding assays using the histamine H1 receptor; dopamine receptors; and α1A, α1B, and α2 adrenergic receptors may be carried out according to the procedures described in U.S. Pat. No. 5,780,485, the disclosure of which is hereby incorporated by reference in its entirety into this application. Binding assays using the dopamine D5 receptor may be carried out according to the procedures described in U.S. Pat. No. 5,882,855, the disclosure of which is hereby incorporated by reference in its entirety into this application. Binding assays for the human α1D adrenergic receptor may be carried out according to the procedures described in U.S. Pat. No. 6,156,518, the disclosure of which is hereby incorporated by reference in its entirety into this application.

[1174] The methods to determine binding affinity at native transporters are described in the following publications: 5HT transporter and NE transporter (Owens et al., 1997), and DA transporter (Javitch et al, 1984).

[1175] The methods to determine activity at monoamine oxidase enzymes (for example, central MAOA and MAOB) are described by Otsuka and Kobayashi, 1964, and were performed by NovaScreen (Hanover, Md.) with the following modifications.

[1176] Central Monoamine Oxidase A Enzyme Assay: Rat brain was used as the enzyme source. The enzyme source was pre-incubated with reference compound (RO 41-1049), test compound (Example 92), and subtype selective blocker (100 nM deprenyl) for 60 minutes at 37° C. in 50 mM KPO4 containing 50 μM EDTA and 10 μM dithiothreitol (pH 7.2 at 25° C.). Substrate ([14C]Serotonin, 45-60 Ci/mmol) was then added and incubated for 30 minutes. The reaction was stopped by the addition of 0.5 ml of 1-2M citric acid. Radioactive product was extracted into xylene/ethyl acetate fluor and compared to control values by scintillation spectrophotometry in order to ascertain any interactions of test compound with central MAOA.

[1177] Central Monoamine Oxidase B Enzyme Assay: Rat brain was used as the enzyme source. The assay was performed as described above for central MAOA, except the reference compound was RO 166491 and the subtype selective blocker was 100 nM clorgyline. Also, the substrate ([14C]Phenylethylamine, 0.056 Ci/mmol) was added and incubated for 10 minutes.

[1178] Materials

[1179] Cell culture media and supplements were from Specialty Media (Lavallette, N.J.). Cell culture plates (150 mm and 96-well microtiter) were from Corning (Corning, N.Y.). Polypropylene 96-well microtiter plates were from Co-star (Cambridge, Mass.). Bovine serum albumin (ultra-fat free, A-7511) was from Sigma (St. Louis, Mo.). All radioligands were from New England Nuclear (Boston, Mass.). Commercially available peptides and peptide analogs were either from Bachem California (Torrance, Calif.) or Peninsula (Belmont, Calif.). All other materials were reagent grade.

[1180] Data Analysis

[1181] Binding data were analyzed using nonlinear regression and statistical techniques available in the GraphPAD Prism package (San Diego, Calif.). Enzymatic assay data were derived from a standard curve of reference compound data.

[1182] The selectivity ratios for compounds of the claimed invention were calculated from the binding data presented in Tables 1-4, Table 7 and Table 9 of the subject application. More specifically, these ratios were calculated by dividing (a) the binding affinity (Ki value) of said compound to a particular receptor or transporter by (b) the binding affinity (Ki value) of said compound to the human GAL3 receptor. The data presented in Table 8 and Table 10, hereinafter, were calculated using the above described method.

[1183] For example, the GAL3/GAL1 selectivity ratio of 10-fold recited in claim 110 of the subject application is characteristic of Example 34. This binding ratio was calculated by dividing (a) the Ki value of 912 for the binding of Example 34 to the GALL receptor (see Table 1) by (b) the Ki value of 23 for the binding of Example 34 to the human GAL3 receptor, thus obtaining the result of 39. Therefore the GAL3/GAL1 binding ratio for Example 34 was determined to be greater than 10-fold.

[1184] B. Results

[1185] The compounds described in the claimed invention were assayed using a panel of cloned receptors and native transporters. The preferred compounds were found to be selective GAL3 antagonists. The binding affinities and selectivity ratios of several compounds are illustrated in Tables 7-10.

[1190] GAL3 Receptor Localization

[1191] A. Materials And Methods

[1192] Preparation Of The Anti-GAL3 Antiserum

[1193] BioSource International, Hopkinton, Mass. performed the immunization and maintenance of rabbits. Following a pre-immune bleed, one peptide for each GAL receptor was injected into a pair of New Zealand white rabbits. The peptide sequences was chosen based on sequence specificity and immunogenicity. The rabbit anti-GAL3 antiserum were raised against C-terminal epitopes corresponding to amino acids 357-370 (Genbank accession number AF073798). The peptides were conjugated to the carrier KLH (keyhole limpet hemocyanin) by a cross linker and subcutaneously injected into the rabbits. The generation of the anti-GAL3 antiserum required OVA followed by a third series of injections with the GAL3 peptide conjugated to tetanus toxoid (TTOX). All injections were done using the Freund's Adjuvant System. Once immunoreactivity was established (see below) the antiserum was affinity purified by passing it over an agarose based column thiol coupled to its antigenic peptide. The column was washed and the antiserum was eluted using a low pH glycine buffer. The purified material was dialyzed, the optical density is taken at 280 λ and the purified antiserum was frozen.

[1194] Characterization Of The Anti-GAL3 Antiserum

[1195] Recombinant GAL1, GAL2, and GAL3 Receptor Transfected Cells

[1196] To determine the ability of the GAL3 antiserum to recognize only the GAL3 receptor protein in vitro, COS-7 cells were grown on poly-L-lysine-coated plastic chamber slides (Nalge Nunc International, Naperville, Ill.) and transfected with recombinant rat GAL receptors (Genbank accession numbers U30290, AF010318, AF073798, respectively) or expression vector only (for mock-transfected cells) as previously described by Borowsky et al. (1999). Receptor expression was confirmed by radioligand binding. Briefly, a subset of slides was washed three times in binding buffer (50 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EDTA, 0.1% bovine serum albumin, and 0.1% bacitracin) and incubated in 500 μl binding buffer containing porcine 125I-galanin (625,000 dpm) plus or minus 10 μM porcine galanin. After incubation at room temperature for 1 hour, the binding buffer was aspirated and slides were rinsed three times in ice cold 50 mM Tris, pH 7.5. Cells were solubilized in 1 ml of 0.1 N NaOH and 0.05% sodium deoxycholate for 30 minutes then transferred to test tubes for gamma counting of 125I. To evaluate antibody activity another subset of slides were washed with phosphate buffered saline (PBS) (Sigma, St. Louis, Mo.) to remove the medium and fixed with 4% paraformaldehyde (PFA) (Sigma, St. Louis, Mo.) then permeabilized using 0.2% Triton X-100/PBS and incubated in 3% normal goat serum for 30 minutes to minimize nonspecific binding of the primary antibody. Cells were incubated overnight at 4° C. with the anti-GAL3 antiserum (1:1000 dilution). The cells were rinsed three times with PBS, incubated for 30 minutes at 25° C. with goat anti-rabbit IgG (1:200 dilution) (Santa Cruz Biotechnology, Santa Cruz, Calif.), rinsed and processed using the peroxidase-antiperoxidase (PAP) reaction of Sternberger et al. (1982). Control experiments for antibody specificity were (1) incubation of the cells in primary antiserum that had been preabsorbed with the respective antigenic peptide (20 μg/ml), (2) incubation without the primary antiserum, or (3) incubation with the primary antiserum replaced by normal goat serum.

[1197] Western Blottinq

[1198] Membranes were prepared from COS-7 cells transiently transfected with the rat recombinant receptors GAL1, GAL2, and GAL3 as previously described (Borowsky et al., 1999). Transfected cells were lysed by sonication in ice-cold sonication buffer (20 mM Tris-HCl, pH 7.7, 5 mM EDTA). Cell lysates were subjected to centrifugation at 4° C. for 10 minutes at 200 g. The supernatant was then fractionated by centrifugation at 4° C. for 18 minutes at 32,000 g. The resulting membrane pellet was suspended into 50 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EDTA. Protein samples (1-10 μg) were solubilized in 2×Laemmli buffer (Bio-Rad, Hercules, Calif.) and fractionated by SDS-PAGE in 10% polyacrylamide gels. Proteins were transferred to polyvinylidine difluoride membranes for immunoblot analysis in ice-cold 25 mM Tris, pH 8, 192 mM glycine, 20% methanol as previously described by Harlow and Lane (1999). Blots were incubated for 1 hour at 25° C. in blocking buffer composed of 5% non-fat dried milk in TTBS (0.1% Tween-20, 500 mM NaCl, 20 mM Tris, pH 7.5) then for 16 hours at 25° C. with the receptor-specific polyclonal antibody (1:1000 dilution in blocking buffer) (0.25 mg/ml for GAL2 or 1.5 mg/ml for GAL3). Immunoreactive bands were detected with the Phototope-HRP Detection Kit for Western Blotting (New England BioLab, Beverly, Mass.) according to the protocol. Briefly, the blots were incubated with horseradish peroxidase-conjugated goat anti-rabbit IgG then developed with a mixture of LumiGLO plus hydrogen peroxide and recorded by chemiluminescence on Kodak Biomax-ML film (Kodak, Rochester, N.Y.).

[1199] Immunohistochemistry

[1200] Male Sprague-Dawley rats, (200-250 g; Charles Rivers, Rochester, N.Y.) were anesthetized by intraperitoneal injection of ketamine 20 mg/kg (RBI, Natick, Mass.) and xylazine 0.2 mg/kg (Bayer, Shawnee Mission, Kans.) then transcardially perfused with 200 ml PBS, pH 7.4 followed by 200 ml 4% PFA in PBS. The brains and spinal cords were removed, blocked, and postfixed in the same fixative for 4 hours at 4° C. then cryoprotected in 30% sucrose in PBS at 4° C. for 48 hours before freezing on dry ice. Coronal brain sections and transverse spinal cord sections were cut at 30 μm using a freezing microtome. Tissue sections were immediately immersed in PBS and stored at 4° C. until use. Sections were processed free-floating according to the protocol outlined in NEN Life Science Products TSA (Tyramide Signal Amplification) Indirect Kit. Briefly, tissue sections were permeabilized in 0.2% Triton X-100 (Sigma, St. Louis, Mo.)/PBS, incubated. in 1% hydrogen peroxide (Sigma, St. Louis, Mo.)/PBS to remove endogenous peroxidase activity then blocked in TNB Buffer (0.1 M Tris-HCl, pH 7.5, 0.15 M NaCl, and 0.5% Blocking Reagent. Sections were incubated for 24 hours at 4° C. in either the anti-GAL2 or anti-GAL3 antiserum (1:100). Following incubation with the primary antiserum, the tissue sections were washed in TNT Buffer (0.1 M Tris-HCl, pH 7.4, 0.15 M NaCl, 0.05% Tween 20) followed by incubation at 25° C. for 30 minutes with horseradish peroxidase (HRP)-conjugated goat anti-rabbit immunoglobulin (1:200) (Sternberger Monoclonals Inc., Lutherville, Md.). Tissue sections were rinsed in TNT Buffer and incubated in a solution containing biotinylated tyramide to amplify the signal then rinsed in TNT buffer and incubated with HRP-conjugated to streptavidin at 25° C. for 30 minutes. An immunoperoxidase reaction was done by incubating the section in 3,3′-diaminobenzidine (DAB) (0.05%) in 0.1 mM Tris, pH 7.4 and adding hydrogen peroxide to 0.006% immediately before use. The reaction was stopped in water and the sections mounted on microscopic slide with mounting medium (40% ethanol: gelatin) and counterstained with Cresyl violet then coverslipped for light microscopy.

[1201] Optimal GAL3 antibody concentrations (1:200) for rat brain sections were determined in preliminary titration experiments. Experimental controls in the tissue sections included (1) incubation in normal rabbit serum or (2) omission of the primary antiserum.

[1202] Analysis.

[1203] COS-7 cells and tissue. sections were examined using a Zeiss Axioscope. A total of 6 male rats were examined with the anti-GAL3 antiserum. The identification of GAL3-LI in the transfected cells and brain regions was based on the presence of immunoreactivity appearing as a brownish precipitate in individual cells and their projections or in the neuropil of the tissue by light microscopy. The descriptions of neuroanatomic boundaries are based on the atlas of Paxinos and Watson (1998).

[1204] B. Results

[1205] Characterization Of The GAL3 Antiserum

[1206] Recombinant GAL1, GAL2, and GAL3 Receptor Transfected Cells

[1207] The ability of the anti-GAL3 antiserum to recognize only the GAL3 receptor protein in vitro was established by performing immunocytochemistry on COS-7 cells transiently transfected with the recombinant receptor proteins for the rat GAL1, GAL2, and GAL3, or mock-transfected with vector only. Specific porcine 125I-galanin binding was detected for all transfectants except mock-transfected cells. An immune response was detected only in the COS-7 cells incubated with the antiserum generated for the particular recombinant receptor. Specifically, no immune reaction was observed with the anti-GAL3 antiserum (1:1000) in GAL1 or GAL2 transfected cells. Furthermore, no visible immune reaction was detected in the mock-transfected cells. Incubation of the cells in primary antiserum that had been preabsorbed with the antigenic peptide (20 pg/ml) or without the primary antiserum or with the primary replaced by normal goat serum did not result in an immune response.

[1208] Taken together, these data demonstrate that the anti-GAL3 antiserum recognizes the receptor against which it was generated and does not show cross reactivity with other known GAL receptors.

[1209] Western Blots

[1210] To determine the specificity of the anti-GAL3 antiserum, COS-7 cells were transiently transfected either with recombinant rat GAL2 or GAL3 receptors or with expression vector only; membranes were then isolated for evaluation by immunoblotting (see FIG. 1). The anti-GAL3 antiserum labeled proteins in membranes only from rat GAL3-transfected cells; a predominant band was evident with an apparent molecular weight of approximately 56 kDa (FIG. 1), somewhat higher than the amino acid-derived value of 40.4 kDa. (For comparison, apparent molecular weights determined by SDS-PAGE are 56 kDa (Servin et al., 1987) or 54 kDa (Chen et al., 1992) for native GAL receptors purified from rat brain and 54 kDa (Amiranoff et al., 1989) for native GAL receptors purified from Rin m 5F cells. These values are all higher than the amino acid-derived value any known GAL receptor subtype, including the value of 38.9 kDa for rat GAL1 (Parker et al., 1995). The apparently high molecular weight observed for rat GAL3 very likely reflects post-translational processing such as glycosylation; note that rat GAL3 contains multiple N-terminal glycosylation sites (Smith et al., 1998). Relative to the predominant band, additional species of higher molecular weight as well as lower molecular weight were labeled by the corresponding antiserum (FIG. 1). These are presumably receptor-related species composed of protein aggregates of C-terminal fragments, as they are absent in mock-transfected cells.

[1211] Immunohistochemical Distribution Of GAL3-LI In The CNS

[1212] GAL3-like immunoreactivity (GAL3-LI) was observed in many regions of the brain, specifically, the neocortex, septum, hippocampus, amygdala, hypothalamus, brainstem, cerebellum, and spinal cord. Throughout the brain and spinal cord GAL3-LI was found to be associated with neuronal profiles however, there was neuropil staining observed in several brain regions. GAL3-LI was high in the septum, basal forebrain, and spinal cord dorsal horn. Lower GAL3-staining was observed in the neocortex, thalamus, hypothalamus, hippocampus, and ventral horn of the spinal cord. Several regions of the CNS almost exclusively expressed GAL3-LI, specifically the caudate-putamen, accumbens nucleus, dorsal raphe and regions of the central gray. There was no observable staining of the fiber tracts.

[1213] The specificity of the anti-GAL3 antiserum was determined in tissue sections by (1) omission of the primary antiserum or (2) incubation with normal rabbit serum. No specific staining was observed in either condition. Preabsorption of the GAL3 primary antiserum with the antigenic peptide (10 μg/ml) decreased but did not completely block staining in the tissue sections as in the transfected cells. This was most likely related to the different localization approaches. In the transiently transfected COS-7 cells the expression of GAL3 receptor protein was relatively high therefore, indirect immunocytochemistry with no amplification was used. In contrast, GAL3 receptor protein expression is presumed to be relatively lower in the tissue sections and for that reason the TSA (amplification) technique was employed. It is possible that because of the amplification (1000-fold) in the TSA technique even small amounts of unabsorbed antiserum may result in a signal.

[1214] Olfactory System

[1215] The main olfactory bulb contained a weak GAL3-LI in scattered cells of the glomerular and internal granule layers; the mitral cells did not contain GAL3-LI. In the anterior olfactory nucleus weak GAL3-LI was detected in random cell bodies and fibers. GAL3-LI was not detected above background in the superficial plexiform layer of the piriform cortex, but weak staining was observed in the neuropil of layer 2 and in the cell bodies of layer 3. Weakly stained cells were observed in the islands of Calleja, and tenia tecta; many cells in the olfactory tubercle were moderately stained.

[1216] Regions Of The Telencephalon

[1217] Cerebral Cortex

[1218] GAL3-LI was widespread in the cerebral cortex and the distribution pattern extended rostrocaudally. Moderately stained GAL3-positive fibers were detected in layers II and III. Numerous pyramidal-shaped somata in layers II through V contained moderate GAL3-LI, and in some instances staining could be seen extending into the cell's dendritic arborizations. In layer VI, GAL3-LI was present only in the cytoplasm of scattered small cells. A weak to moderate GAL3-LI was seen in numerous cell bodies in the anterior cingulate and retrosplenial cortices. The entorhinal cortex contained GAL3-positive cell bodies and a finely stained neuropil.

[1219] Septal Region

[1220] An extensive and densely stained fiber network was seen throughout the entire lateral, intermediate and medial septal nuclei. The dorsal division of the lateral septum contained scarce moderately GAL3-positive somata.

[1221] Basal Ganglia And Basal Forebrain

[1222] GAL3-LI was detected in the receiving regions of the basal ganglia; thus GAL3 may mediate the internal organization of the basal ganglia. Many moderately labeled medium-sized round cells were evenly distributed throughout the caudate-putamen in addition to a weakly immuncreactive neuropil. Moderately positive cells were visible along the medial border of the globus pallidus. Numerous moderately GAL3-positive cell bodies and fibers were present in the shell and core of the accumbens nucleus. The cell bodies of the subthalamic nucleus, a relay nucleus in the basal ganglia, contained weak GAL3-LI.

[1223] Moderately GAL3-positive cells were present in several nuclei of the basal forebrain: the horizontal limb of the diagonal band, the basal nucleus of Meynert, and the substantia innominata.

[1224] Hippocampal Region

[1225] A large number of granule cells in the dorsal dentate gyrus and pyramidal-shaped cells in the polymorphic dentate gyrus displayed a weak to moderate GAL3-LI. Clusters of very fine light to moderately GAL3-immunoreactive fiber networks were evident in the molecular layer of the dentate gyrus. Light to moderate GAL3-LI was observed in the perikarya of the pyramidal-shaped cells in Ammon's horn and as a fine neuropil in the stratum oriens and stratum radiatum of fields CA1, CA2, and CA3. Labeled cells and fibers were observed in the rostral subiculum. Caudally, moderate to weak GAL3-LI was seen in the granule cells of the ventral dentate gyrus with weaker labeling in random cell bodies throughout the dorsal subiculum and the ventral CA1 field.

[1226] Amygdala And Extended Amygdala

[1227] In general, GAL3-LI was weak throughout the amygdala. Scattered cell bodies and fibers exhibited weak staining in several nuclei: the lateral, medial, posteroventral, posterodorsal medial, and posteromedial cortical nuclei. GAL3-positive cells were present in the anterior cortical amygdaloid nuclei, amygdalopiriform transition and amygdalohippocampal areas. Very fine GAL3-positive fibers with scattered moderately labeled cells were detected in the central amygdaloid nucleus. The divisions of the bed nucleus of the stria terminalis displayed a weak cellular GAL3-LI; moderately stained fibers were present in the nucleus of the lateral olfactory tract.

[1228] Regions Of The Diencephalon

[1229] Hypothalamus And Preoptic Area

[1230] GAL3-LI was fairly extensive in the hypothalamus. Moderate GAL3-LI could be seen in the large cell bodies extending into the dendrites in the magnocellular preoptic nucleus. Relatively high GAL3 staining was observed in cells and neuropil of the suprachiasmatic and arcuate nuclei and as a dense fiber network in the median eminence. Moderately stained GAL3-positive fibers could be seen in the optic chiasm near the ventral border of the superchiasmatic nucleus. Moderate labeling was detected in cells and neuropil in several nuclei: the lateroanterior, lateral and anterior hypothalamus, supraoptic, dorsomedial, paraventricular parvocellular, periformical, ventromedial, and medial mammillary nuclei, and in cell bodies and fibers of the ventromedial nucleus.

[1231] Thalamus And Epithalamus

[1232] GAL3-LI was generally weak throughout the thalamus. The highest GAL3-LI in the thalamus was detected in the cell bodies and neuropil of the geniculate nuclei and the anteromedial thalamic nucleus. The reticular, paraventricular, central, mediodorsal, anterodorsal, anteromedial, anteroventral, lateral posterior, anterior pretectal, and posterior thalamic nuclei, the zona incerta and the nucleus of the fields of Forel contained light to moderately stained cells. The ventroposterior lateral and ventroposterior medial nuclei contained GAL3-positive cells and fibers. Weak labeling was detected in the cell bodies in the medial habenular nucleus with scarce positive cells in the lateral habenular nucleus.

[1233] Midbrain/Mesencephalon

[1234] The neuropil and scattered cells in the zonal layer of the superior colliculus were moderately labeled. Light to moderately stained GAL3-positive cell bodies were observed in the superficial, intermediate gray and deep gray layers with a random positive cell in the optic nerve layer. Moderately labeled cell bodies were present in several midbrain regions: the dorsal and lateral ventral divisions of the central gray, the external cortex of the inferior colliculus, oculomotor, and rhabdoid nuclei and tegmental area. Labeled cells were detected within the dorsal raphe and projections from these cells were seen converging toward the midline of the raphe. In the midbrain tegmentum, moderate GAL3-LI was present in the perikarya and dendrites of the large neurons of the red nucleus and retrorubral field. Small-sized pyramidal shaped weakly stained cell bodies were seen throughout the substantia nigra, reticular part with weaker labeling of the neuropil; moderately dense labeling of neuronal perikarya was detected in the compact part. The pontine nucleus displayed a light to moderate GAL3-positive neuropil.

[1235] GAL3-LI was extensive throughout the brain stem. Moderate GAL3-LI was detected in the neuropil and cell bodies of several nuclei: the medial vestibular, prepositus hypoglossal, dorsal cochlear, and facial nuclei. Very weak GAL3-LI was observed in the gracile nucleus and no immunoreactivity was detected in the cuneate and hypoglossal nuclei. Moderate to light labeling was evident in large cell bodies and dendrites in the spinal vestibular and the dorsal motor nucleus vagus; weaker labeling was seen in the gigantocellular reticular, gigantocellular reticular, alpha, and lateral paragigantocellular nuclei. Numerous moderately labeled small round cells and neuropil was detected in the nucleus of the solitary tract; the parvicellular reticular nucleus contained moderately labeled small cells. Intense staining was observed in fibers in the area postrema and in cell bodies in the locus coeruleus. Light to moderate GAL3-LI was observed in scattered somata throughout the layers of the caudal spinal trigeminal nucleus, and labeled fibers were also seen in the superficial layer. Moderately heavy GAL3-LI was present in neuronal perikarya and dendrites in the trapezoid nucleus and in fibers in the subnuclei A, B, and K of the inferior olive. The pontine reticular nucleus contained low to moderate labeling of large-sized neurons.

[1236] Cerebellum

[1237] In the cerebellar cortex, moderate GAL3-LI appeared to be present in fibers that passed from the granule cell layer through the Purkinje cell layer. The molecular layer contained a weak to moderately stained very fine fiber network. Weak staining was visible in the neuronal perikarya of the deep cerebellar nuclei.

[1238] Spinal cord

[1239] GAL3-positive cells were detected throughout the dorsal and ventral horns of the spinal cord. In the superficial laminae of the dorsal horn small moderately immunoreactive cells and neuropil were observed. Moderately stained cell bodies were scattered throughout laminae III, IV and the laminae of the ventral horn, while labeled cells and neuropil were seen around the central canal in lamina X. GAL3-positive axons were observed in the ventral funiculus converging toward the ventral root. All levels of the spinal cord exhibited a comparable laminar distribution.

[1240] The distribution of rat GAL3 protein in the CNS usinq receptor subtype selective polyclonal antibodies and tyramide signal amplification (TSA) immunocytochemistry is illustrated in Table 12. These were qualitative evaluations for the rat GAL3 receptor protein distribution based on the relative intensity of the chromogen (3,3′-diaminobenzidine) observed in individual cells at the microscopic level.

[1241] A total of 4 rat brains were analyzed for this study. As shown in Table 12, the strength of the signal obtained in various regions of the rat brain was graded as weak (+), or moderate (++) or intense(+++).

[1242] Discussion

[1243] The GAL3 antiserum was characterized using recombinant GAL receptors in transiently transfected COS-7 cells and Western blot analysis and the specificity of the GAL3 antiserum to recognize only the cograte receptor in vitro was established. The anatomical distribution of the GAL3 receptor protein in the rat CNS was determined using a modified immunohistochemical technique to enhance sensitivity and delectability via tyramide signal amplification (Toda et al., 1999).

[1244] The results indicate that the expression GAL3-LI was primarily found in neuronal profiles with neuropil labeling detectable in several areas. In general, the distribution of GAL3-LI is in good agreement with the reported distribution for galanin-LI, galanin binding sites, and GAL3 mRNA in the rat brain (for recent review, Branchek et al., 2000). Overall, GAL3-LI was found to be extensively distributed throughout the brain: the neocortex, septum, hippocampus, amygdala, hypothalamus, brain stem, cerebellum and spinal cord. Paralleling the distribution of galanin binding sites, GAL3-LI was observed in ventral regions of the brain, specifically the horizontal diagonal band, substantia innominata, olfactory tubercle, and ventral hippocampus. However, there was discordance between 125I-galanin binding and the GAL3 receptor protein distribution particularly in the neocortex, dorsal hippocampus, and cerebellum (Skofitsch and Jacobowitz, 1986), regions where binding sites have not been identified by receptor autoradiography.

[1245] The present results showed several interesting observations in the distribution of GAL3-LI relating to potential therapeutic applications for the GAL3 receptor.

[1246] Galanin has been reported to be involved in the regulation of cholinergic neurotransmission in the hippocampus and in the basal forebrain via modulation of acetylcholine release. Therefore, the development of a galanin receptor antagonist to block the inhibition of firing of cholinergic neurons may have a potential therapeutic application in the treatment of some of the learning and memory deficits of Alzheimer's disease (AD) (for review, Mufson et al. 1998). GAL3-LI was identified in several cholinergic regions of the rat brain: the horizontal diagonal band, basal nucleus of Meynert, substantia innominata, bed nucleus of the stria terminalis, and the hippocampus. The GAL3 protein has been localized to other regions of the brain, the entorhinal cortex and locus coeruleus, that exhibit increased galanin receptor binding and galanin expression in AD providing further evidence for the potential involvement of GAL3 in AD.

[1247] Substantial evidence suggests that galanin is involved in the regulation of energy and nutrient balance. Injections of galanin into the hypothalamus have been shown to increase food intake. Concordant with the localization of GAL3 mRNA in the hypothalamus, GAL3-LI was detected in several hypothalamic nuclei involved in the regulation of feeding: the paraventricular, arcuate, dorsomedial, ventromedial and medial preoptic areas. This localization suggests that the GAL3 receptor may be a potential therapeutic target in the regulation of food intake and body weight and thus be useful in the treatment of eating disorders.

[1248] GAL3 may be a potential therapeutic target in the development of analgesic drugs. The presence of the receptor in the target regions of nociceptive primary afferent fibers, the superficial layers of the spinal trigeminal nucleus and dorsal horn of the spinal cord, suggests that GAL3 could potentially modulate nociceptive information from the periphery. GAL3 is in a position to potentially mediate the influence of excitatory glutamatergic nociceptive primary afferents from the dorsal root ganglia in the superficial layers of the spinal cord.

[1249] The localization of the GAL3 protein in the dorsal raphe and locus coeruleus suggests a potential therapeutic application of galanin receptor antagonists in the treatment of affective disorders by attenuating galanin's inhibitory tone on both of these regions.

[1250] A decrease in central serotonin (5-HT) neurotransmission has been implicated in affective disorders. GAL3 antagonists could possibly act via GAL3 receptors on the cell bodies of dorsal raphe neurons to increase firing rate of raphe neurons thus increasing 5-HT release in the telencephalon and diencephalon. Another possible site of action for a GAL3 antagonist could be on postsynaptic GAL3 receptors in the limbic forebrain to block the putative ability of galanin to negatively regulate 5-HT1A receptor transmission (Misane et al, 1998).

[1251] Unlike the dorsal raphe cells, the cells of the locus coeruleus express abundant galanin under normal conditions and it has been proposed that galanin may be released from dendrites and soma of the noradrenergic cell bodies (for review, Hökfelt et al., 1998). The ascending afferent projections of the locus coeruieus are extensive throughout the brain. Changes in the noradrenergic system have been hypothesized to be involved in affective behaviors and symptoms (for review, Weiss et al., 1993). The ventral tegmental area (VTA) receives projections from the locus coeruleus that have been reported to co-localize galanin and noradrenaline. It has been proposed that in certain pathological states (ex. stress induced depression) galanin released from noradrenergic terminals in the VTA inhibits dopaminergic neurons in the region that results in decreased dopamine release in the forebrain regions, particularly the accumbens nucleus and prefrontal cortex. This decrease in dopamine release produces a decreased motor activation and anhedonia. GAL3 has been identified in all of these regions and thus presents itself as a potential therapeutic target in the treatment of affective disorders. Drugs that would effectively decrease galanin's release in the VTA whether at the level of the locus coeruleus (somatodendritic GAL3 receptors to decrease the activity of LC cells) or in the VTA itself (presynaptically on NE/GAL terminals in the VTA or via GAL3 receptors on VTA-DA neurons to prevent the hyperpolarization V-LA-DA cells by released galanin) would produce an antidepressant-like effect.
