1. Field of the Invention The present invention relates to Diaminoalkylene Compounds, compositions comprising an effective amount of a Diaminoalkylene Compound and methods for treating or preventing a condition such as pain, comprising administering to an animal in need thereof an effective amount of a Diaminoalkylene Compound.

2. Background of the Invention Pain is the most common symptom for which patients seek medical advice and treatment. Pain can be acute or chronic. While acute pain is usually self- limited, chronic pain persists for 3 months or longer and can lead to significant changes in a patient's personality, lifestyle, functional ability and overall quality of life (K. M.

Foley, Pain, in Cecil Textbook of Medicine 100-107 (J. C. Bennett and F. Plum eds. , 20th ed. 1996)).

Chronic pain can be classified as either nociceptive or neuropathic.

Nociceptive pain includes tissue injury-induced pain and inflammatory pain such as that associated with arthritis. Neuropathic pain is caused by damage to the peripheral or central nervous system and is maintained by aberrant somatosensory processing. There is a large body of evidence relating activity at both Group I metabotropic glutamate receptors, i. e., metabotropic glutamate receptor 1 ("mGluR1") and metabotropic glutamate receptor 5 ("mGluR5") (M. E. Fundytus, CNS Drugs 15: 29-58 (2001) ), and vanilloid receptors ("VR1") (V. Di Marzo et al., Current Opinion in Neurobiology 12 : 372-379 (2002) ) to pain processing. Inhibiting mGluR1 or mGluR5 reduces pain, as shown by in vivo treatment with antibodies selective for either mGluR1 or mGluR5, where neuropathic pain in rats was attenuated (M. E. Fundytus et al., NeuroReport 9 : 731-735 (1998) ). It has also been shown that antisense oligonucleotide knockdown of mGluR1 alleviates both neuropathic and inflammatory pain (M. E. Fundytus et al., Brit.

J. Pharmacol. 132: 354-367 (2001); M. E. Fundytus et al., Pharmacol., Biochem. &

Behavior 73: 401-410 (2002) ). Small molecule antagonists for mGluR5-attenuated pain in in vivo animal models are disclosed in, e. g. , K. Walker et al., Neurophannacology 40: 1-9 (2000) and A. Dogrul et al., Neuroscience Let. 292: 115-118 (2000)).

Nociceptive pain has been traditionally managed by administering non- opioid analgesics, such as acetylsalicylic acid, choline magnesium trisalicylate, acetaminophen, ibuprofen, fenoprofen, diflusinal, and naproxen; or opioid analgesics, including morphine, hydromorphone, methadone, levorphanol, fentanyl, oxycodone, and oxymorphone. Id. In addition to the above-listed treatments, neuropathic pain, which can be difficult to treat, has also been treated with anti-epileptics (e. g. , gabapentin, carbamazepine, valproic acid, topiramate, phenytoin), NMDA antagonists (e. g., ketamine, dextromethorphan), topical lidocaine (for post-herpetic neuralgia), and tricyclic antidepressants (e. g. , fluoxetine, sertraline and amitriptyline).

UI is uncontrollable urination, generally caused by bladder-detrusor- muscle instability. UI affects people of all ages and levels of physical health, both in health care settings and in the community at large. Physiologic bladder contraction results in large part from acetylcholine-induced stimulation of post-ganglionic muscarinic-receptor sites on bladder smooth muscle. Treatments for UI include the administration of drugs having bladder-relaxant properties, which help to control bladder-detrusor-muscle overactivity. For example, anticholinergics such as propantheline bromide and glycopyrrolate, and combinations of smooth-muscle relaxants such as a combination of racemic oxybutynin and dicyclomine or an anticholinergic, have been used to treat UI (see, e. g., A. J. Wein, Urol. Clin. N. Am. 22: 557-577 (1995); Levin et al., J. Urol. 128: 396-398 (1982); Cooke et al., S. Afr. Med. J. 63: 3 (1983); R. K.

Mirakhur et al., Anaesthesia 38: 1195-1204 (1983) ). These drugs are not effective, however, in all patients having uninhibited bladder contractions.

None of the existing commercial drug treatments for UI, however, has achieved complete success in all classes of UI patients, nor has treatment occurred without significant adverse side effects. For example, drowsiness, dry mouth, constipation, blurred vision, headaches, tachycardia, and cardiac arrhythmia, which are related to the anticholinergic activity of traditional anti-UI drugs, can occur frequently and adversely affect patient compliance. Yet despite the prevalence of unwanted anticholinergic effects in many patients, anticholinergic drugs are currently prescribed

for patients having UI (see The Merck Manual of Medical Infonnation 631-634 (R.

Berkow ed. , 1997).

Certain pharmaceutical agents have been administered for treating addiction. U. S. Patent No. 5,556, 838 to Mayer et al. discloses the use of nontoxic NMDA-blocking agents co-administered with an addictive substance to prevent the development of tolerance or withdrawal symptoms. U. S. Patent No. 5,574, 052 to Rose et al. discloses co-administration of an addictive substance with an antagonist to partially block the pharmacological effects of the addictive substance. U. S. Patent No. 5,075, 341 to Mendelson et al. discloses the use of a mixed opiate agonist/antagonist to treat cocaine and opiate addiction. U. S. Patent No. 5,232, 934 to Downs discloses administration of 3-phenoxypyridine to treat addiction. U. S. Patents No. 5,039, 680 and 5,198, 459 to Imperato et al. disclose using a serotonin antagonist to treat chemical addiction. U. S.

Patent No. 5,556, 837 to Nestler et. al. discloses infusing BDNF or NT-4 growth factors to inhibit or reverse neurological adaptive changes that correlate with behavioral changes in an addicted individual. U. S. Patent. No. 5,762, 925 to Sagan discloses implanting encapsulated adrenal medullary cells into an animal's central nervous system to inhibit the development of opioid tolerance. U. S. Patent No. 6,204, 284 to Beer et al. discloses racemic ()-1- (3, 4-dichlorophenyl) -3-azabicyclo [3. 1. 01hexane for use in the prevention or relief of a withdrawal syndrome resulting from addiction to drugs and for the treatment of chemical dependencies. Glutamate release is enhanced during opioid withdrawal (K. Jhamandas et al., J. Neurosience 16: 2758-2766 (1996) ). Recent evidence suggests a role for Group I mGluRs in opioid tolerance and dependence. An interaction between opioids and mGluRs was demonstrated when it was shown that an antagonist at Group I mGluRs significantly attenuated withdrawal symptoms in opioid-dependent rats (M. E. Fundytus et al., Brit. J. Phannacol. 113: 1215-1220 (1994)).

More recent results show that antisense oligonucleotide knockdown of mGluR1 reduces protein kinase C activity (M. E. Fundytus et al., Brit. J. Pharmacol. 132: 354-367 (2001) ), which may be associated in the development of opioid tolerance and dependence (see also M. E. Fundytus, CNS Drugs 15: 29-58, (2001) ). Very recently, it has been shown that antisense oligonucleotide knockdown of mGluR1 attenuates the development of opioid tolerance (R. N. Sharif et al., Brit. J. Pharmacol. 136: 865-872 (2002) ). Selective antagonists of the mGluR5 receptor have also been shown to exert

anti-dependence activity in vivo (C. Chiamulera et al., Nature Neuroscience 4: 873-874 (2001)).

Without treatment, Parkinson's disease progresses to a rigid akinetic state in which patients are incapable of caring for themselves. Death frequently results from complications of immobility, including aspiration pneumonia or pulmonary embolism.

Drugs commonly used for the treatment of Parkinson's disease include carbidopa/levodopa, pergolide, bromocriptine, selegiline, amantadine, and trihexyphenidyl hydrochloride. There remains, however, a need for drugs useful for the treatment of Parkinson's disease and having an improved therapeutic profile.

Currently, benzodiazepines are the most commonly used anti-anxiety agents for generalized anxiety disorder. Benzodiazepines, however, carry the risk of producing impairment of cognition and skilled motor functions, particularly in the elderly, which can result in confusion, delerium, and falls with fractures. Sedatives are also commonly prescribed for treating anxiety. The azapirones, such as buspirone, are also used to treat moderate anxiety. The azapirones, however, are less useful for treating severe anxiety accompanied with panic attacks. Antagonists of the mGluR5 receptor have also been shown to exert anxiolytic and anti-depressant activity in in vivo animal models (E. Tatarczynska et al., Br. J. Pharmacol. 132 (7): 1423-1430 (2001) and P. J. M.

Will et al., Trends in Pharmacological Sciences 22 (7): 331-37 (2001)).

Examples of drugs for treating a seizure and epilepsy include carbamazepine, ethosuximide, gabapentin, lamotrigine, phenobarbital, phenytoin, primidone, valproic acid, trimethadione, benzodiazepines, y-vinyl GABA, acetazolamide, and felbamate. Anti-seizure drugs, however, can have side effects such as drowsiness; hyperactivity; hallucinations; inability to concentrate; central and peripheral nervous system toxicity, such as nystagmus, ataxia, diplopia, and vertigo; gingival hyperplasia; gastrointestinal disturbances such as nausea, vomiting, epigastric pain, and anorexia; endocrine effects such as inhibition of antidiuretic hormone, hyperglycemia, glycosuria, osteomalacia; and hypersensitivity such as scarlatiniform rash, morbilliform rash, Stevens-Johnson syndrome, systemic lupus erythematosus, and hepatic necrosis; and hematological reactions such as red-cell aplasia, agranulocytosis, thrombocytopenia, aplastic anemia, and megaloblastic anemia (see, e. g., The Merck Manual of Medical Information 345-350 (R. Berkow ed. , 1997).

Symptoms of strokes vary depending on what part of the brain is affected.

Symptoms include loss of or abnormal sensations in an arm or leg or one side of the body, weakness or paralysis of an arm or leg or one side of the body, partial loss of vison or hearing, double vision, dizziness, slurred speech, difficulty in thinking of the appropriate word or saying it, inability to recognize parts of the body, unusual movements, loss of bladder control, imbalance, and falling, and fainting. The symptoms can be permanent and can be associated with coma or stupor. Examples of drugs for treating strokes include anticoagulants such as heparin, drugs that break up clots such as streptokinase or tissue plasminogen activator, and drugs that reduce swelling such as mannitol or corticosteroids. The MerokManual of Medical Information 352-355 (R.

Berkow ed. , 1997).

Pruritus is an unpleasant sensation that prompts scratching.

Conventionally, pruritus is treated by phototherapy with ultraviolet B or PUVA or with therapeutic agents such as naltrexone, nalmefene, danazol, and tricyclic antidepressants.

Selective antagonists of the metabotropic glutamate receptor 5 ("mGluR5") have been shown to exert analgesic activity in in vivo animal models (K.

Walker et al., Europharmacology 40 : 1-9 (2000) and A. Dogrul et al., Neuroscience Let., 292 (2) : 115-118 (2000)).

Selective antagonists of the mGluR5 receptor have also been shown to exert anti-Parkinson activity in vivo (K. J. Ossowska et al., Neuropharmacology 41 (4): 413-20 (2001) and P. J. M. Will et al., Trends in Pharmacological Sciences 22 (7) : 331-37 (2001)).

Selective antagonists of the mGluR5 receptor have also been shown to exert anti-dependence activity in vivo (C. Chiamulera et al., Nature Neuroscience 4 (9): 873-74 (2001)).

International Publication No. WO 99/37304 by Rohne-Poulenc Rorer Pharmaceuticals, Inc. discloses oxoazaheterocyclic compounds useful for inhibiting factor Xa.

International Publication No. WO 99/31064 by Klinge Pharma GMBH discloses aryl-substituted 3-pyridlylalkine carboxamides useful as cystostatic and immunosuppressive agents.

There remains, however, a clear need in the art for new drugs useful for treating or preventing pain, UI, an addictive disorder, Parkinson's disease, parkinsonism,

anxiety, epilepsy, a seizure, a stroke, a pruritic condition, psychosis, a cognitive disorder, a memory deficit, restricted brain function, Huntington's chorea, ALS, dementia, retinopathy, a muscle spasm, a migraine, vomiting, dyskinesia or depression in an animal.

4.5 Therapeutic/Prophylactic Administration and Compositions of the Invention Due to their activity, the Diaminoalkylene Compounds are advantageously useful in veterinary and human medicine. As described above, the Diaminoalkylene Compounds are useful for treating or preventing a Condition in an animal in need thereof.

When administered to an animal, the Diaminoalkylene Compounds are administered as a component of a composition that comprises a pharmaceutically acceptable carrier or excipient. The present compositions, which comprise a Diaminoalkylene Compound, can be administered orally. The Diaminoalkylene Compounds of the invention can also be administered by any other convenient route, for example, by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e. g. , oral, rectal, and intestinal mucosa, etc.) and can be administered together with another therapeutically active agent. Administration can be systemic or local. Various delivery systems are known, e. g. , encapsulation in liposomes, microparticles, microcapsules, capsules, etc., and can be used to administer the Diaminoalkylene Compound.

Methods of administration include, but are not limited to, intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, oral, sublingual, intracerebral, intravaginal, transdermal, rectal, by inhalation, or topical, particularly to the ears, nose, eyes, or skin. The mode of administration is left to the discretion of the practitioner. In most instances, administration will result in the release of the Diaminoalkylene Compounds into the bloodstream.

In specific embodiments, it can be desirable to administer the Diaminoalkylene Compounds locally. This can be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e. g. , in

conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository or enema, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers.

In certain embodiments, it can be desirable to introduce the Diaminoalkylene Compounds into the central nervous system or gastrointestinal tract by any suitable route, including intraventricular, intrathecal, and epidural injection, and enema. Intraventricular injection can be facilitated by an intraventricular catheter, for example, attached to a reservoir, such as an Ommaya reservoir.

Pulmonary administration can also be employed, e. g., by use of an inhaler or nebulizer, and formulation with an aerosolizing agent, or via perfusion in a fluorocarbon or synthetic pulmonary surfactant. In certain embodiments, the Diaminoalkylene Compounds can be formulated as a suppository, with traditional binders and excipients such as triglycerides.

In another embodiment, the Diaminoalkylene Compounds can be delivered in a vesicle, in particular a liposome (see Langer, Science 249: 1527-1533 (1990) and Treat et al., Liposomes in the Therapy of Infectious Disease and Cancer 317- 327 and 353-365 (1989).

In yet another embodiment, the Diaminoalkylene Compounds can be delivered in a controlled-release system or sustained-release system (see, e. g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984) ). Other controlled-or sustained-release systems discussed in the review by Langer, Science 249: 1527-1533 (1990) can be used. In one embodiment, a pump can be used (Langer, Science 249: 1527-1533 (1990); Sefton, CRC Crit. Ref. Biomed. Eng. 14: 201 (1987); Buchwald et al., Surgery 88 : 507 (1980); and Saudek et al., N. Engl. J. Med. 321: 574 (1989) ). In another embodiment, polymeric materials can be used (see Medical Applications of Controlled Release (Langer and Wise eds. , 1974); Controlled Drug Bioavailability, Drug Product Design and Performance (Smolen and Ball eds., 1984) ; Ranger and Peppas, J. Macromol. Sci. Rev. Macromol. Chem. 23: 61 (1983); Levy et al., Science 228: 190 (1985); During et al., Ann. Neurol. 25: 351 (1989); and Howard et al., J. Neurosurg. 71: 105 (1989) ). In yet another embodiment, a controlled-or sustained- release system can be placed in proximity of a target of the Diaminoalkylene

Compounds, e. g., the spinal column, brain, or gastrointestinal tract, thus requiring only a fraction of the systemic dose.

The present compositions can optionally comprise a suitable amount of a pharmaceutically acceptable excipient so as to provide the form for proper administration to the animal.

Such pharmaceutical excipients can be liquids, such as water and oils, including those of petroleum, animal, vegetable, or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical excipient can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea and the like.

In addition, auxiliary, stabilizing, thickening, lubricating, and coloring agents can be used. In one embodiment, the pharmaceutically acceptable excipients are sterile when administered to an animal. Water, and in one embodiment physiological saline, is a particularly useful excipient when the Diaminoalkylene Compound is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid excipients, particularly for injectable solutions. Suitable pharmaceutical excipients also include starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents.

The present compositions can take the form of solutions, suspensions, emulsions, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the composition is in the form of a capsule (see e. g., U. S. Patent No. 5,698, 155). Other examples of suitable pharmaceutical excipients are described in Remington's Pharmaceutical Sciences 1447-1676 (Alfonso R. Gennaro ed., l9th ed. 1995), incorporated herein by reference.

In one embodiment, the Diaminoalkylene Compounds are formulated in accordance with routine procedures as a composition adapted for oral administration to human beings. Compositions for oral delivery can be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs, for example. Orally administered compositions can contain one or more agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents

such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions can be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for orally administered compositions. In these latter platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture.

These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time-delay material such as glycerol monostearate or glycerol stearate can also be used. Oral compositions can include standard excipients such as mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, and magnesium carbonate. In one embodiment, the excipients are of pharmaceutical grade.

In another embodiment, the Diaminoalkylene Compounds can be formulated for intravenous administration. Typically, compositions for intravenous administration comprise sterile isotonic aqueous buffer. Where necessary, the compositions can also include a solubilizing agent. Compositions for intravenous administration can optionally include a local anesthetic such as lidocaine to lessen pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the Diaminoalkylene Compounds are to be administered by infusion, they can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the Diaminoalkylene Compounds are administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients can be mixed prior to administration.

The Diaminoalkylene Compounds can be administered by controlled- release or sustained-release means or by delivery devices that are known to those skilled in the art. Examples include, but are not limited to, those described in U. S. Patent Nos.: 3,845, 770; 3,916, 899; 3,536, 809; 3,598, 123; 4,008, 719; 5,674, 533; 5,059, 595; 5,591, 767; 5,120, 548; 5,073, 543; 5,639, 476; 5,354, 556; and 5,733, 566, each of which is incorporated herein by reference. Such dosage forms can be used to provide controlled-

or sustained-release of one or more active ingredients using, for example, hydropropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems, multilayer coatings, microparticles, liposomes, microspheres, or a combination thereof to provide the desired release profile in varying proportions.

Suitable controlled-or sustained-release formulations known to those skilled in the art, including those described herein, can be readily selected for use with the active ingredients of the invention. The invention thus encompasses single unit dosage forms suitable for oral administration such as, but not limited to, tablets, capsules, gelcaps, and caplets that are adapted for controlled-or sustained-release.

Controlled-or sustained-release pharmaceutical compositions can have a common goal of improving drug therapy over that achieved by their non-controlled or non-sustained-release counterparts. In one embodiment, a controlled-or sustained- release composition comprises a minimal amount of a Diaminoalkylene Compound to cure or control the condition in a minimum amount of time. Advantages of controlled- or sustained-release compositions include extended activity of the drug, reduced dosage frequency, and increased patient compliance. In addition, controlled-or sustained- release compositions can favorably affect the time of onset of action or other characteristics, such as blood levels of the Diaminoalkylene Compound, and can thus reduce the occurrence of adverse side effects.

Controlled-or sustained-release compositions can initially release an amount of a Diaminoalkylene Compound that promptly produces the desired therapeutic or prophylactic effect, and gradually and continually release other amounts of the Diaminoalkylene Compound to maintain this level of therapeutic or prophylactic effect over an extended period of time. To maintain a constant level of the Diaminoalkylene Compound in the body, the Diaminoalkylene Compound can be released from the dosage form at a rate that will replace the amount of Diaminoalkylene Compound being metabolized and excreted from the body. Controlled-or sustained-release of an active ingredient can be stimulated by various conditions, including but not limited to, changes in pH, changes in temperature, concentration or availability of enzymes, concentration or availability of water, or other physiological conditions or compounds.

The amount of the Diaminoalkylene Compound that is effective for the treatment or prevention of a condition can be determined using standard clinical techniques. In addition, in vitro or in vivo assays can optionally be employed to help

identify optimal dosage ranges. The precise dose to be employed will also depend on the route of administration, and the seriousness of the Condition and can be decided according to the judgment of a practitioner and/or each animal's circumstances. Suitable effective dosage amounts, however, range from about 0.01 mg/kg of body weight to about 2500 mg/kg of body weight, although they are typically about 100 mg/kg of body weight or less. In one embodiment, the effective dosage amount ranges from about 0.01 mg/kg of body weight to about 100 mg/kg of body weight of a Diaminoalkylene Compound, in another embodiment, from about 0.02 mg/kg of body weight to about 50 mg/kg of body weight, and in another embodiment, from about 0.025 mg/kg of body weight to about 20 mg/kg of body weight. In one emobiment, an effective dosage amount is administred about every 24 h until the Condition is abated. In another embodiment, an effective dosage amount is admininstered about every 12 h until the Condition is abated. In another embodiment, an effective dosage amount is admininstered about every 8 h until the Condition is abated. In another embodiment, an effective dosage amount is admininstered about every 6 h until the Condition is abated.

In another embodiment, an effective dosage amount is admininstered about every 4 h until the Condition is abated. The effective dosage amounts described herein refer to total amounts administered; that is, if more than one Diaminoalkylene Compound is administered, the effective dosage amounts correspond to the total amount administered.

Where a cell capable of expressing mGluR5 or mGluRl is contacted with a Diaminoalkylene Compound in vitro, the amount effective for inhibiting the mGluR5 or mGluRl receptor function in a cell will typically range from about 0.01 llg/L to about 5 mg/L, in one embodiment, from about 0.01 u, g/L to about 2.5 mg/L, in another embodiment, from about 0.01 llg/L to about 0.5 mg/L, and in another embodiment, from about 0. 01, ug/L to about 0.25 mg/L of a solution or suspension of a pharmaceutically acceptable carrier or excipient. In one embodiment, the volume of solution or suspension comprising the Diaminoalkylene Compound is from about 0. 01 uL to about 1 mL. In another embodiment, the volume of solution or suspension is about 200 pL.

Where a cell capable of expressing mGluR5 or mGluRl is contacted with a Diaminoalkylene Compound in vivo, the amount effective for inhibiting the receptor function in a cell will typically range from about 0.01 mg/kg of body weight to about 2500 mg/kg of body weight, although it typically ranges from about 100 mg/kg of body weight or less. In one embodiment, the effective dosage amount ranges from about 0.01

mg/kg of body weight to about 100 mg/kg of body weight of a Diaminoalkylene Compound, in another emodiment, from about 0.02 mg/kg of body wieght to about 50 mg/kg of body weight, and in another embodiment, from about 0.025 mg/kg of body weight to about 20 mg/kg of body weight. In one embodiment, an effective dosage amount is administered about every 24 h. In another embodiment, an effective dosage amount is administered about every 12 h. In another embodiment, an effective dosage amount is administered about every 8 h. In another embodiment, an effective dosage amount is administered about every 6 h. In another embodiment, an effective dosage amount is administered about every 4 h.

The Diaminoalkylene Compounds can be assayed in vitro or M vivo for the desired therapeutic or prophylactic activity prior to use in humans. Animal model systems can be used to demonstrate safety and efficacy.

The present methods for treating or preventing a Condition in an animal in need thereof can further comprise administering another therapeutic agent to the animal being administered a Diaminoalkylene Compound. In one embodiment, the other therapeutic agent is administered in an effective amount.

The present methods for inhibiting mGluR5 function in a cell capable of expressing mGluR5 can further comprise contacting the cell with an effective amount of another therapeutic agent.

The present methods for inhibiting mGluRl function in a cell capable of expressing mGluRl can further comprise contacting the cell with an effective amount of another therapeutic agent Effective amounts of the other therapeutic agents are known to those skilled in the art. However, it is well within the skilled artisan's purview to determine the other therapeutic agent's optimal effective-amount range. In one embodiment of the invention, where another therapeutic agent is administered to an animal, the effective amount of the Diaminoalkylene Compound is less than its effective amount would be where the other therapeutic agent is not administered. In this case, without being bound by theory, it is believed that the Diaminoalkylene Compounds and the other therapeutic agent act synergistically to treat or prevent a Condition.

Cell Cultures: Primary glial cultures were prepared from cortices of Sprague-Dawley 18 days old embryos. The cortices were dissected and then dissociated by trituration. The resulting cell homogenate was plated onto poly-D-lysine precoated T175 flasks (BIOCOAT, commercially available from Becton Dickinson and Company Inc. of Franklin Lakes, NJ) in Dulbecco's Modified Eagle's Medium ("DMEM,"pH 7.4), buffered with 25 mM HEPES, and supplemented with 15% fetal calf serum ("FCS," commercially available from Hyclone Laboratories Inc. of Omaha, NE), and incubated at 37°C and 5% CO2. After 24 hours, FCS supplementation was reduced to 10%. On day six, oligodendrocytes and microglia were removed by strongly tapping the sides of the flasks. One day following this purification step, secondary astrocytes cultures were established by subplating onto 96 poly-D-lysine precoated T175 flasks (BIOCOAT) at a density of 65,000 cells/well in DMEM and 10% FCS. After 24 hours, the astrocytes were washed with serum free medium and then cultured in DMEM, without glutamate, supplemented with 0.5% FCS, 20 mM HEPES, 10 ng/mL epidermal growth factor ("EGF"), 1 mM sodium pyruvate, and 1X penicillin/streptomycin at pH 7.5 for 3 to 5 days at 37°C and 5% COæ The procedure allowed the expression of the mGluR5 receptor by astrocytes, as demonstrated by S. Miller et al., J. Neuroscience 15 (9): 6103- 6109 (1995).

Assay Protocol: After 3-5 days incubation with EGF, the astrocytes were washed with 127 mM NaCI, 5 mM KCl, 2 mM MgCl2, 700 mM NaH2PO4, 2 mM CaCl2, 5 mM NaHCO3, 8 mM HEPES, 10 mM Glucose at pH 7.4 ("Assay Buffer") and loaded with the dye FLUO-4 (commercially available from Molecular Probes Inc. of Eugene, OR) using 0.1 mL of Assay Buffer containing FLUO-4 (3 mM final). After 90 minutes of dye loading, the cells were then washed twice with 0.2 mL Assay Buffer and resuspended in 0.1 mL of Assay Buffer. The plates containing the astrocytes were then transferred to a Fluorometric Imaging Plate reader ("FLIPR") (commercially available from Molecular Devices Corporation of Sunnyvale, CA) for the assessment of calcium

mobilization flux in the presence of glutamate and in the presence or absence of antagonist. After monitoring fluorescence for 15 seconds to establish a baseline, DMSO solutions containing various concentrations of the Diaminoalkylene Compounds diluted in Assay Buffer (0.05 mL of 4X dilutions for competition curves) was added to the cell plate and fluorescence were monitored for 2 minutes. 0.05 mL of a 4X glutamate solution (agonist) were then added to each well to provide a final glutamate concentration in each well of 10 mM. Plate fluorescence was then monitored for an additional 60 seconds after agonist addition. The final DMSO concentration in the assay was 1.0%. In each experiment, fluorescence was monitored as a function of time and the data analyzed using Microsoft Excel and GraphPad Prism. Dose-response curves were fit using a non-linear regression to determine the ICso value. Compound 1465 (d) showed an ICso value of 17 7.70 nM (mean of 4 experiments).

5.15 Example 15: Binding of a Diaminoalkylene Compound to mGluR5 Alternatively, the following assay can be used to demonstrate that Diaminoalkylene Compounds bind to and modulate the activity of mGluR5.

40,000 CHO-rat mGluR5 cells/well are plated into 96 well plate (Costar 3409, Black, clear bottom, 96 well, tissue culture treated) for an about 16 hour incubation in Dulbecco's Modified Eagle's Medium (DMEM, pH 7.4) and supplemented with glutamine, 10% FBS, 1% Pen/Strep, and 50011g/mL Geneticin. CHO-rat mGluR5 cells are washed and treated with Optimem medium and incubated for 1-4 hours prior to loading cells. Cell plates are then washed with loading buffer (127 mM NaCl, 5 mM KCI, 2 mM MgCl2, 700 uM Na H2PO4, 2 mM CaCl2, 5 mM NaHCO3, 8 mM Hepes, and 10 mM glucose, pH 7.4) and then incubated with 3uM Fluo 4 (commercially available from Molecular probes Inc. of Eugene, OR) in 0.1 mL of loading buffer. After 90 minutes of dye loading, the cells are then washed twice with 0.2 mL loading buffer and resuspended in 0.1 mL loading buffer.

The plates containing the CHO-rat mGluR5 cells are then transferred to a FLIPR for the assessment of calcium mobilization flux in the presence of glutamate and in the presence or absence of test compounds. After monitoring fluorescence for 15 seconds to establish a baseline, DMSO solutions containing various concentrations of the test compound diluted in loading buffer (0.05 mL of 4X dilutions for the competition

curves) are added to the cell plate and fluorescence is monitored for 2 minutes. 0.05 mL of 4X glutamate solution (agonist) is then added to each well to provide a final glutamate concentration in each well of 10 uM. Plate fluorescence is then monitored for an additional 60 seconds after agonist addition. The final DMSO concentration in the assay is 1. 0%. In each experiment, fluorescence is monitored as a function of time and the data analyzed using Microsoft Excel and GraphPad Prism. Dose-response curves are fit using a non-linear regression to determine the Icso value. In each experiment, each data point is determined two times.

5.16 Example 16: In Vivo Assays for Treatment or Prevention of Pain The following assays can be used to demonstrate that Diaminoalkylene Compounds are useful for treating or preventing pain.

Test Animals: Each experiment uses rats weighing between 200-260 g at the start of the experiment. The rats are group-housed and have free access to food and water at all times, except prior to oral administration of a Diaminoalkylene Compound when food is removed for 16 hours before dosing. A control group acts as a comparison to rats treated with a Diaminoalkylene Compound. The control group is administered the carrier for the Diaminoalkylene Compound. The volume of carrier administered to the control group is the same as the volume of carrier and Diaminoalkylene Compound administered to the test group.

Acute Pain: To assess the actions of the Diaminoalkylene Compounds for the treatment or prevention of acute pain the rat tail flick test can be used. Rats are gently restrained by hand and the tail exposed to a focused beam of radiant heat at a point 5 cm from the tip using a tail flick unit (Model 7360, commercially available from Ugo Basile of Italy). Tail flick latencies are defined as the interval between the onset of the thermal stimulus and the flick of the tail. Animals not responding within 20 seconds are removed from the tail flick unit and assigned a withdrawal latency of 20 seconds.

Tail flick latencies are measured immediately before (pre-treatment) and 1,3, and 5 hours following administration of a Diaminoalkylene Compound. Data are expressed as tail flick latency (s) and the percentage of the maximal possible effect (% MPE), i. e., 20 seconds, is calculated as follows:

[ (post administration latency)- (pre-administration latency)] % MPE= X 100 (20 s pre-administration latency) The rat tail flick test is described in F. E. D'Amour et al.,"A Method for Determining Loss of Pain Sensation,"J. Pharmacol. Exp. Ther. 72: 74-79 (1941).

Acute pain can also be assessed by measuring the animal's response to noxious mechanical stimuli by determining the paw withdrawal threshold ("PWT"), as described below.

Inflammatory Pain: To assess the actions of the Diaminoalkylene Compounds for the treatment or prevention of inflammatory pain the Freund's complete adjuvant ("FCA") model of inflammatory pain is used. FCA-induced inflammation of the rat hind paw is associated with the development of persistent inflammatory mechanical hyperalgesia and provides reliable prediction of the anti-hyperalgesic action of clinically useful analgesic drugs (L. Bartho et al.,"Involvement of Capsaicin-sensitive Neurones in Hyperalgesia and Enhanced Opioid Antinociception in Inflammation," Naunyn-Schmiedeberg's Archives of Pharmacol. 342: 666-670 (1990) ). The left hind paw of each animal is administered a 50 uL intraplantar injection of 50% FCA. 24 hour post injection, the animal is assessed for response to noxious mechanical stimuli by determining the PWT, as described below. Rats are then administered a single injection of 1,3, 10 or 30 mg/kg of either a Diaminoalkylene Compound; 30 mg/kg of a control selected from Celebrex, indomethacin or naproxen; or carrier. Responses to noxious mechanical stimuli are then determined 1, 3,5 and 24 hours post administration.

Percentage reversal of hyperalgesia for each animal is defined as: [ (post administration PWT)- (pre-administration PWT)] % Reversal = X 100 [ (baseline PWT)- (pre-administration PWT)]

Neuropathic Pain: To assess the actions of the Diaminoalkylene Compounds for the treatment or prevention of neuropathic pain either the Seltzer model or the Chung model can be used.

In the Seltzer model, the partial sciatic nerve ligation model of neuropathic pain is used to produce neuropathic hyperalgesia in rats (Z. Seltzer et al.,"A Novel Behavioral Model of Neuropathic Pain Disorders Produced in Rats by Partial Sciatic Nerve Injury,"Pain 43 : 205-218 (1990) ). Partial ligation of the left sciatic nerve is performed under isoflurane/02 inhalation anaesthesia. Following induction of anesthesia, the left thigh of the rat is shaved and the sciatic nerve exposed at high thigh level through a small incision and is carefully cleared of surrounding connective tissues at a site near the trocanther just distal to the point at which the posterior biceps semitendinosus nerve branches off of the common sciatic nerve. A 7-0 silk suture is inserted into the nerve with a 3/8 curved, reversed-cutting mini-needle and tightly ligated so that the dorsal 1/3 to l/2 of the nerve thickness is held within the ligature. The wound is closed with a single muscle suture (4-0 nylon (Vicryl) ) and vetbond tissue glue.

Following surgery, the wound area is dusted with antibiotic powder. Sham-treated rats undergo an identical surgical procedure except that the sciatic nerve is not manipulated.

Following surgery, animals are weighed and placed on a warm pad until they recover from anesthesia. Animals are then returned to their home cages until behavioral testing begins. The animal is assessed for response to noxious mechanical stimuli by determining PWT, as described below, prior to surgery (baseline), then immediately prior to and 1,3 and 5 hours after drug administration for the left rear paw of the animal.

Percentage reversal of neuropathic hyperalgesia is defined as: [ (post administration PWT)- (pre-administration PWT)] % Reversal = X 100 [ (baseline PWT)- (pre-administration PWT)] In the Chung model, the spinal nerve ligation model of neuropathic pain is used to produce mechanical hyperalgesia, thermal hyperalgesia and tactile allodynia in rats. Surgery is performed under isoflurane/O2 inhalation anaesthesia. Following induction of anaesthesia a 3 cm incision is made and the left paraspinal muscles are

separated from the spinous process at the L4-S2 levels. The L6 transverse process is carefully removed with a pair of small rongeurs to identify visually the L4-L6 spinal nerves. The left 11, (or Ls and L6) spinal nerve (s) is isolated and tightly ligated with silk thread. A complete hemostasis is confirmed and the wound is sutured using non- absorbable sutures, such as nylon sutures or stainless steel staples. Sham-treated rats undergo an identical surgical procedure except that the spinal nerve (s) is not manipulated. Following surgery animals are weighed, administered a subcutaneous (s. c.) injection of saline or ringers lactate, the wound area is dusted with antibiotic powder and they are kept on a warm pad until they recover from the anesthesia. Animals are then returned to their home cages until behavioral testing begins. The animals are assessed for response to noxious mechanical stimuli by determining PWT, as described below, prior to surgery (baseline), then immediately prior to and 1,3 and 5 hours after being administered a Diaminoalkylene Compound for the left rear paw of the animal. The animal can also be assessed for response to noxious thermal stimuli or for tactile allodynia, as described below. The Chung model for neuropathic pain is described in S. H. Kim, "An Experimental Model for Peripheral Neuropathy Produced by Segmental Spinal Nerve Ligation in the Rat,"Pain 50 (3): 355-363 (1992).

Response to Mechanical Stimuli as an Assessment of Mechanical Hyperalgesia : The paw pressure assay can be used to assess mechanical hyperalgesia.

For this assay, hind paw withdrawal thresholds (PWT) to a noxious mechanical stimulus are determined using an analgesymeter (Model 7200, commercially available from Ugo Basile of Italy) as described in C. Stein, "Unilateral Inflammation of the Hindpaw in Rats as a Model of Prolonged Noxious Stimulation: Alterations in Behavior and Nociceptive Thresholds,"Pharmacol. Biochem. and Behavior 31 : 451-455 (1988). The maximum weight that can be applied to the hind paw is set at 250 g and the end point is taken as complete withdrawal of the paw. PWT is determined once for each rat at each time point and only the affected (ipsilateral) paw is tested.

Response to Thermal Stimuli as an Assessment of Thermal Hyperalgesia : The plantar test can be used to assess thermal hyperalgesia. For this test, hind paw withdrawal latencies to a noxious thermal stimulus are determined using a plantar test apparatus (commercially available from Ugo Basile of Italy) following the technique described by K. Hargreaves et al.,"A New and Sensitive Method for Measuring Thermal Nociception in Cutaneous Hyperalgesia,"Pain 32 (1) : 77-88 (1988). The maximum

exposure time is set at 32 seconds to avoid tissue damage and any directed paw withdrawal from the heat source is taken as the end point. Three latencies are determined at each time point and averaged. Only the affected (ipsilateral) paw is tested.

Assessment of Tactile Allodynia : To assess tactile allodynia, rats are placed in clear, plexiglass compartments with a wire mesh floor and allowed to habituate for a period of at least 15 minutes. After habituation, a series of von Frey monofilaments are presented to the plantar surface of the left (operated) foot of each rat. The series of von Frey monofilaments consists of six monofilaments of increasing diameter, with the smallest diameter fiber presented first. Five trials are conducted with each filament with each trial separated by approximately 2 minutes. Each presentation lasts for a period of 4-8 seconds or until a nociceptive withdrawal behavior is observed. Flinching, paw withdrawal or licking of the paw are considered nociceptive behavioral responses.

5.17 Example 17: In Vivo Assays for Treatment or Prevention of Anxiety The elevated plus maze test or the shock-probe burying test can be used to assess the anxiolytic activity of Diaminoalkylene Compounds in rats or mice.

The Elevated Plus Maze Test: The elevated plus maze consists of a platform with 4 arms, two open and two closed (50 x 10 x 50 cm enclosed with an open roof). Rats (or mice) are placed in the center of the platform, at the crossroad of the 4 arms, facing one of the closed arms. Time spent in the open arms vs. the closed arms and number of open arm entries during the testing period are recorded. This test is conducted prior to drug administration and again after drug administration. Test results are expressed as the mean time spent in open arms and the mean number of entries into open arms. Known anxiolytic drugs increase both the time spent in open arms and number of open arm entries. The elevated plus maze test is described in D. Treit, "Animal Models for the Study of Anti-anxiety Agents: A Review, "Neuroscience & Biobehavioral Reviews 9 (2): 203-222 (1985).

The Shock-Probe Burying Test: For the shock-probe burying test the testing apparatus consists of a plexiglass box measuring 40 x 30 x 40 cm, evenly covered with approximately 5 cm of bedding material (odor absorbent kitty litter) with a small hole in one end through which a shock probe (6.5 cm long and 0. 5 cm in diameter) is inserted. The plexiglass shock probe is helically wrapped with two copper wires through

which an electric current is administered. The current is set at 2 mA. Rats are habituated to the testing apparatus for 30 min on 4 consecutive days without the shock probe in the box. On test day, rats are placed in one corner of the test chamber following drug administration. The probe is not electrified until the rat touches it with its snout or fore paws, at which point the rat receives a brief 2 mA shock. The 15 min testing period begins once the rat receives its first shock and the probe remains electrified for the remainder of the testing period. The shock elicits burying behavior by the rat.

Following the first shock, the duration of time the rat spends spraying bedding material toward or over the probe with its snout or fore paws (burying behavior) is measured as well as the number of contact-induced shocks the rat receives from the probe. Known anxiolytic drugs reduce the amount of burying behavior. In addition, an index of the rat's reactivity to each shock is scored on a 4 point scale. The total time spent immobile during the 15 min testing period is used as an index of general activity. The shock-probe burying test is described in D. Treit, 1985, supra.

5.18 Example 18: In Vivo Assays for Treatment or Prevention of an Addictive Disorder The conditioned place preference test or drug self-administration test can be used to assess the ability of Diaminoalkylene Compounds to attenuate the rewarding properties of known drugs of abuse.

The Conditioned Place Preference Test: The apparatus for the conditioned place preference test consists of two large compartments (45 x 45 x 30 cm) made of wood with a plexiglass front wall. These two large compartments are distinctly different. Doors at the back of each large compartment lead to a smaller box (36 x 18 x 20 cm) box made of wood, painted grey, with a ceiling of wire mesh. The two large compartments differ in terms of shading (white vs. black), level of illumination (the plexiglass door of the white compartment is covered with aluminum foil except for a window of 7 x 7 cm), texture (the white compartment has a 3 cm thick floor board (40 x 40 cm) with nine equally spaced 5 cm diameter holes and the black has a wire mesh floor), and olfactory cues (saline in the white compartment and 1 mL of 10% acetic acid in the black compartment). On habituation and testing days, the doors to the small box remain open, giving the rat free access to both large compartments.

The first session that a rat is placed in the apparatus is a habituation session and entrances to the smaller grey compartment remain open giving the rat free access to both large compartments. During habituation, rats generally show no preference for either compartment. Following habituation, rats are given 6 conditioning sessions. Rats are divided into 4 groups: carrier pre-treatment + carrier (control group), Diaminoalkylene Compound pre-treatment + carrier, carrier pre-treatment + morphine, Diaminoalkylene Compound pre-treatment + morphine. During each conditioning session the rat is injected with one of the drug combinations and confined to one compartment for 30 min. On the following day, the rat receives a carrier + carrier treatment and is confined to the other large compartment. Each rat receives three conditioning sessions consisting of 3 drug combination-compartment and 3 carrier- compartment pairings. The order of injections and the drug/compartment pairings are counterbalanced within groups. On the test day, rats are injected prior to testing (30 min to 1 hour) with either morphine or carrier and the rat is placed in the apparatus, the doors to the grey compartment remain open and the rat is allowed to explore the entire apparatus for 20 min. The time spent in each compartment is recorded. Known drugs of abuse increase the time spent in the drug-paired compartment during the testing session.

If the Diaminoalkylene Compound blocks or reduces the acquisition of morphine conditioned place preference (reward), there will be no difference in time spent in each side in rats pre-treated with a Diaminoalkylene Compound and the group will not be different from the group of rats that was given carrier + carrier in both compartments.

Data will be analyzed as time spent in each compartment (drug combination-paired vs. carrier-paired). Generally, the experiment is repeated with a minimum of 3 doses of a Diaminoalkylene Compound.

The Drug Self-Administration Test: The apparatus for the drug self- administration test is a standard commercially available operant conditioning chamber.

Before drug trials begin rats are trained to press a lever for a food reward. After stable lever pressing behavior is acquired, rats are tested for acquisition of lever pressing for drug reward. Rats are implanted with chronically indwelling jugular catheters for i. v. administration of compounds and are allowed to recover for 7 days before training begins. Experimental sessions are conducted daily for 5 days in 3 hour sessions. Rats are trained to self-administer a known drug of abuse, such as morphine. Rats are then presented with two levers, an"active"lever and an"inactive"lever. Pressing of the

active lever results in drug infusion on a fixed ratio 1 (FR1) schedule (i. e., one lever press gives an infusion) followed by a 20 second time out period (signaled by illumination of a light above the levers). Pressing of the inactive lever results in infusion of excipient. Training continues until the total number of morphine infusions stabilizes to within 10% per session. Trained rats are then used to evaluate the effect of Diaminoalkylene Compounds pre-treatment on drug self-administration. On test day, rats are pre-treated with a Diaminoalkylene Compound or excipient and then are allowed to self-administer drug as usual. If the Diaminoalkylene Compound blocks or reduces the rewarding effects of morphine, rats pre-treated with the Diaminoalkylene Compound will show a lower rate of responding compared to their previous rate of responding and compared to excipient pre-treated rats. Data is analyzed as the change in number of drug infusions per testing session (number of infusions during test session-number of infusions during training session).

5.19 Example 19 : Functional Assay for Characterizing mGluR1 Antagonistic Properties Functional assays for the characterization of mGluRl antagonistic properties are known in the art. For example, the following procedure can be used.

A CHO-rat mGluR1 cell line is generated using cDNA encoding rat mGluR1 receptor (M. Masu et al., Nature 349: 760-765 (1991) ). The cDNA encoding rat mGluRla receptor can be obtained from, e. g., Prof. S. Nakanishi (Kyoto, Japan).

40,000 CHO-rat mGluRl cells/well are plated into a COSTAR 3409, black, clear bottom, 96 well, tissue culture treated plate (commercially available from Fisher Scientific of Chicago, IL) and are incubated in Dulbecco's Modified Eagle's Medium (DMEM, pH 7.4) supplemented with glutamine, 10% FBS, 1% Pen/Strep, and 500 ug/mL Geneticin for about 12 h. The CHO-rat mGluR1 cells are then washed and treated with OPTIMEM medium (commercially available from Invitrogen, Carlsbad, CA) and incubated for a time period ranging from 1 to 4 hours prior to loading the cells with the dye FLUO-4. After incubation, the cell plates are washed with loading buffer (127 mM NaCI, 5 mM KCI, 2 mM MgCl2, 700 uM, NaH2PO4, 2 mM CaCl2, 5 mMNaHCO3, 8 mM HEPES, and 10 mM glucose, pH 7.4) and incubated with 3, uM FLUO-4 in 0.1 mL loading buffer for 90 min. The cells are then washed twice with 0.2 mL loading buffer, resuspended in 0.1 mL of loading buffer, and transferred to a FLIPR

for measurement of calcium mobilization flux in the presence of glutamate and in the presence or absence of a Diaminoalkylene Compound.

To measure calcium mobilization flux, fluoresence is monitored for about 15 s to establish a baseline and DMSO solutions containing various concentrations of a Diaminoalkylene Compound ranging from about 50 uM to about 0. 8 nM diluted in loading buffer (0.05 mL of a 4X dilution) are added to the cell plate and fluoresence is monitored for about 2 min. 0.05 mL of a 4X glutamate solution (agonist) is then added to each well to provide a final glutamate concentration in each well of 10 uM and fluoresence is monitored for about one additional min. The final DMSO concentration in the assay is 1%. In each experiment fluoresence is monitored as a function of time and the data is analyzed using a non-linear regression to determine the ICso value. In each experiment each data point is determined twice.
