In addition to the foregoing beneficial uses for the modulators of H3 receptor activity disclosed herein, the compounds disclosed herein are believed to be useful in the treatment of several additional diseases and disorders, and in the amelioration of symptoms thereof. Without limitation, these include the following.
Histamine [2-(imidazol-4-yl)ethylamine] is a transmitter substance present in both the central and peripheral nervous system. In the central nervous system (CNS) cell bodies of histaminergic neurons are located almost exclusively in the tuberomammillary nuclei (TMN) of the posterior hypothalamus. Histaminergic neurons extend from the TMN to innervate all major areas of the brain, suggesting involvement in a wide variety of physiological processes (see:
Haas and Panula in Nat. Rev. Neurosci. 2003, 4, 121-130).
Histamine exerts its physiological effects through four distinct G-protein coupled receptors (GPCRs), termed H1-H4. The H3 receptor was first identified in 1983, when it was determined that the H3 receptor acted as an autoreceptor controlling both the synthesis and release of histamine (see: Arrang et al. Nature 1983, 302, 832-7). H3 receptors also function as heteroceptors, modulating the release of a number of other transmitter substances including serotonin, acetylcholine, dopamine and noradrenaline (see: Brown et al. Prog Neurobio12003, 63, 637-672). Thus, there are a number of therapeutic applications for ligands which target the H3 receptor, where the ligand functions as either an antagonist or inverse agonist (for reviews see: Leurs et al. Nat Rev Drug Discov 2005, 4, 107-120; Passani et al. Trends Pharmacol Sci 2004, 25, 618-624).
Accordingly, preclinical studies have identified a number of indications which are amenable to treatment with H3 antagonists and inverse agonists, such as compounds of the present invention. These include cognitive disorders (Passani et al. Trends Pharmacol Sci 2004, 25, 618-624), epilepsy (Vohora et al. Pharmacol Biochem Behav 2001, 68, 735-741), depression (Perez-Garcia et a. Psychopharmacol 1999, 142, 215-220), narcolepsy (Tedford et al. Soc Neurosci Abstr 2000, 26, 460.3), obesity (Hancock, Curr Opin Investig Drugs 2003, 4, 1190-1197), motion sickness and vertigo (Pan et al. Methods Find Exp Clin Pharmacol. 1998, 20, 771-777), disorders of sleep and wakefulness (Parmentier et al. J Neurosci.
2002, 22, 7695-7711; Ligneau et al. J Pharmacol Exp Ther. 1998, 287, 658-666), attention deficit hyperactivity disorder (ADHD), (Fox et al. Behav Brain Res. 2002, 131, 151-61), schizophrenia (Fox et al. J
Pharmacol Exp Ther. 2005, 313, 176-190), and treatment of upper airway allergic responses (U.S. Pat. Nos. 5,217,986; 5,352,707 and 5,869,479). H3 antagonists have been shown to increase wakefulness (e.g. Lin J. S. et al. Brain Research 1990, 523, 325-330). This effect demonstrates that H3 antagonists can also be useful for conditions associated with excessive daytime sleepiness such as narcolepsy, sleep apnea, time zone change disorder, fibromyalgia, ~Ga k :~ !E , 1~ iE
and muitip~e scterosis (Parmentier R, et al., J Neurosci. 2002, 22, 7695-7711;
Ligneau X. et al. J
Pharmacol Exp Ther. 1998, 287, 658-666). For additional information, see reviews by Leurs et al., in Nat Rev Drug Discov 2005, 4, 107-120, and Vohora, 2004, Investigational Drugs 7, 667-673.
Histamine H3-receptor antagonists and inverse agonists can be used to treat the somnolence syndrome associated with different pathological conditions, for example, sleep apnea and Parkinson's disease or circumstances associated with lifestyle, for example, daytime somnolence from sleep deprivation as a result of nocturnal jobs, overwork, or jet-lag (see Passani et al., Trends Pharrnacol. Sci. 2004, 25, 618-625). Somnolence is one of the major problems of public health because of its high prevalence (19-37% of the general population) and risk for causing work and traffic accidents.
Sleep apnea (alternatively sleep apnoea) is a common sleep disorder characterized by brief interruptions of breathing during sleep. These episodes, called apneas, last 10 seconds or more and occur repeatedly throughout the night. People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of the disturbances in their sleep. The most common type of sleep apnea is obstructive sleep apnea (OSA), caused by relaxation of soft tissue in the back of the throat that blocks the passage of air. Central sleep apnea (CSA) is caused by irregularities in the brain's normal signals to breathe. The hallmark symptom of the disorder is excessive daytime sleepiness. Additional symptoms of sleep apnea include restless sleep, loud snoring (with periods of silence followed by gasps), falling asleep during the day, morning headaches, trouble concentrating, irritability, forgetfulness, mood or behaviour changes, weight gain, increased heart rate, anxiety, and depression.
Few drug-based treatments of obstructive sleep apnea are known despite over two decades of research and tests. Oral administration of the methylxanthine theophylline (chemically similar to caffeine) can reduce the number of episodes of apnea, but can also produce side effects such as palpitations and insomnia. Theophylline is generally ineffective in adults with OSA, but is sometimes used to treat CSA, and infants and children with apnea. In 2003 and 2004, some neuroactive drugs, particularly modexn-generation antidepressants including mirtazapine, have been reported to reduce incidences of obstructive sleep apnea.
When other treatments do not completely treat the OSA, drugs are sometimes prescribed to treat a patient's daytime sleepiness or somnolence. These range from stimulants such as amphetamines to modern anti-narcoleptic medicines. The drug modafinil is seeing increased use in this role as of 2004.

In addition, for example, histamine H3-receptor antagonists and inverse agonists can be used to treat narcolepsy (Tedford et al. Soc. Neurosci. Abstr. 1999, 25, 460.3). Narcolepsy is a neurological condition most often characterized by Excessive Daytime Sleepiness (EDS), episodes of sleep and disorder of REM or rapid eye movement sleep. The main characteristic of ",, !{ ){ if!.{iK,){ a narco'lepsy is overwhelming txcessive Daytime Sleepiness (EDS), even after adequate nighttime sleep. A person with narcolepsy is likely to become drowsy or to fall asleep, often at inappropriate times and places. In addition, nighttime sleep may be fragmented with frequent wakenings. Classic symptoms of narcolepsy include, for example, cataplexy which is sudden episodes of loss of muscle function, ranging from slight wealrness (such as limpness at the neck or knees, sagging facial muscles, or inability to speak clearly) to complete body collapse.
Episodes may be triggered by sudden emotional reactions such as laughter, anger, surprise, or fear, and may last from a few seconds to several minutes. Another symptom of narcolepsy is sleep paralysis, which is the temporary inability to talk or move when waking up. Other symptoms include, for example, hypnagogic hallucinations which are vivid, often frightening, dream-like experiences that occur while dozing, falling asleep and/or while awakening, and automatic behaviour which occurs when a person continues to function (talking, putting things away, etc.) during sleep episodes, but awakens with no memory of performing such activities.
Daytime sleepiness, sleep paralysis, and hypnagogic hallucinations also occur in people who do not have narcolepsy, such as in people who are suffering from extreme lack of sleep. Cataplexy is generally considered unique to narcolepsy.
Currently the treatments available for narcolepsy treat the symptoms, but not the underlying cause. For cataplexy and REM-sleep symptoms, antidepressant medications and other drugs that suppress REM sleep are prescribed. The drowsiness is normally treated using stimulants such as methylphenidate (Ritalin), amphetamines (Adderall), dextroamphetamine (Dexedrine), methamphetamine (Desoxyn), modafinil (Provigil), etc. Other medications used are codeine and selegiline. The cataplexy is treated using clomipramine, imipramine, or protriptyline but this need only be done in severe cases. The drug gamma-hydroxybutyrate (GHB) (Xyrem) is approved in the USA by the Food and Drug Administration to treat both the cataplexy and excessive daytime sleepiness associated with narcolepsy.
Interestingly, modafinil (Provigil) has recently been shown to increase hypothalamic histamine release (Ishizuka et al. Neurosci. Lett. 2003, 339, 143-146).
In addition, recent studies using the classic Doberman model of narcolepsy with a non-imidazole histamine H3-receptor antagonist showed that a histamine H3-receptor antagonist can reduce the number of narcoleptic attacks and the duration of the attaclcs (Carruthers Ann. Meet.
Eur. Histamine Res. Soc. 2004, Abs. p31).
In summary, histamine H3-receptor antagonists and inverse agonists can be used for the treatment and/or prevention of conditions associated with excessive daytime sleepiness such as hypersomnia, narcolepsy, sleep apnea, time zone change disorder, and other disorders which are associated with excessive daytime sleepiness such as fibromyalgia, and multiple sclerosis (Parmentier et al., J. Neurosci. 2002, 22, 7695-7711; Ligneau et al. J.
Pharmacol. Exp. Tlier.
1998, 287, 658-666). Other conditions include excessive sleepiness due to shift work, medical 1iatric disorders, "narcolepsy, primary hypersomnia, and the like. Histamine receptor antagonists and inverse agonists can also be used occasionally to promote wakefulness or vigilance in shift workers, slepp deprivation, post anesthesia grogginess, drowiness as a side effect from a medication, military use and the like.
In addition, wakefulness is a prerequisite for several brain functions including attention, leatning, and memory and is required for appropriate behaviours in response to environmental challenges. Histamine H3-receptor antagonists and inverse agonists have been shown to improve cognitive performance in various animal models (Hancock and Fox in Milestones in Drug Therapy, ed. Buccafusco, 2003). These compounds can be used as pro-cognitive agents and can increase vigilance. Therefore, histamine H3-receptor antagonists and inverse agonists can be used in aging or degenerative disorders in which vigilance, attention and memory are impaired, for example, as in Alzheimer's disease or other dementias.
'Alzheimer's disease (AD), a neurodegenerative disorder, is the most common cause of dementia. It is characterized clinically by progressive cognitive deterioration together with neuropsychiatric symptoms and behavioural changes. The most striking early symptom is memory loss, which usually manifests as minor forgetfulness that becomes steadily more pronounced with illness progression, with relative preservation of older memories. As the disorder progresses, cognitive (intellectual) impairment extends to the domains of language, slcilled movements, recognition and functions closely related to the frontal and temporal lobes of the brain such as decision-making and planning. There is currently no cure for AD, although there are drugs which offer symptomatic benefit, specifically with respect to short-term memory impairment. These drugs include acetylcholinesterase inhibitors such as donepezil (Aricept), galantamine (Razadyne) and rivastigmine (Exelon) and NMDA antagonists such as memantine.
Histamine H3-receptor antagonists and inverse agonists can be used to treat or prevent cognitive disorders (Passani et al. Trends Plaarznacol. Sci. 2004, 25, 618-625), epilepsy (Vohora et al. Pharrnacol. Biochena. Behav. 2001, 68, 735-741), depression (Perez-Garcia et al.
Psychopliarrnacol. 1999, 142, 215-220), attention deficit hyperactivity disorder (ADHD), (Fox et al. Behav. Brain Res. 2002, 131, 151-61), and schizophrenia (Fox et al. J.

Ther. 2005, 313, 176-190). These indications are described briefly below. For additional information, see reviews by Leurs et al., Nat. Rev. Drug. Discov. 2005, 4, 107-120, and Vohora Investigational Drugs 2004, 7, 667-673). Histamine H3-receptor antagonists or inverse agonists can also be used as a novel therapeutic approach to restore cortical activation in comatose or brain-traumatized patients (Passani et al., Trends in Phartnacol. Sci. 2004, 25, 618-625).
As stated above, histamine H3-receptor antagonists and inverse agonists can be used to treat or prevent epilepsy. Epilepsy (often referred to as a seizure disorder) is a chronic neurological condition characterized by recurrent unprovoked seizures. In terms of their pattern of activity, seizures may be described as either partial (focal) or generalized. Partial seizures edpart''of t~e brain, whereas generalized seizures involve the entire cortex.
There are many different epilepsy syndromes, each presenting with its own unique combination of seizure type, typical age of onset, EEG findings, treatment, and prognosis.
Some common seizure syndromes include, for example, infantile spasms (West syndrome), childhood absence epilepsy, and benign focal epilepsy of childhood (Benign Rolandic epilepsy), juvenile myoclonic epilepsy, temporal lobe epilepsy, frontal lobe epilepsy and Lennox-Gastaut syndrome.
Compounds of the present invention can be used in combination with various known drugs. For example, compounds of the present invention can be used with one or more drugs that prevent seizures or reduce seizure frequency: these include carbamazepine (common brand name Tegretol), clobazam (Frisium), clonazepam (Klonopin), ethosuximide (Zarontin), felbamate (Felbatol), fosphenytoin (Cerebyx), flurazepam (Dalmane), gabapentin (Neurontin), lamotrigine (Lamictal), levetiracetam (Keppra), oxcarbazepine (Trileptal), mephenytoin (Mesantoin), phenobarbital (Luminal), phenytoin (Dilantin), pregabalin (Lyrica), primidone (Mysoline), sodium valproate (Epilim), tiagabine (Gabitril), topiramate (Topamax), valproate semisodium (Depakote), valproic acid (Depakene, Convulex), and vigabatrin (Sabril). Other drugs are commonly used to abort an active seizure or interrupt a seizure flurry; these include diazepam (Valium) and lorazepam (Ativan). Drugs used only in the treatment of refractory status epilepticus include paraldehyde (Paral) and pentobarbital (Nembutal).
As stated above, a histamine H3-receptor antagonist or inverse agonist can be used as the sole agent of treatment or can be used in combination with other agents.
For example, Vohora et al. show that a histamine H3-receptor antagonist can work as an anti-epilepsy, anti-seizure drug and also showed effect with sub-effective doses of the H3-receptor antagonist in combination with sub-effective doses of known anti-epileptic drugs (Vohora et al. Pharnzacol.
Biochern. Behav. 2001, 68, 735-741).
Perez-Garcia et al. (Psychopharrnacol. 1999, 142, 215-220) tested the ability of a histamine H3-receptor agonist and antagonist on experimental mouse models of anxiety (elevated plus-maze) and depression (forced swimming test). They found that while the compounds did not have a significant effect on the model of anxiety, a H3 -receptor antagonist did have a significant dose-dependent effect in the model of depression. Thus, histamine H3-receptor antagonists or inverse agonists can have antidepressant effects.
Clinical depression is a state of sadness or melancholia that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living. Clinical depression affects about 16% of the population on at least one occasion in their lives. Clinical depression is currently the leading cause of disability in the U.S. as well as other countries, and is expected to become the second leading cause of disability worldwide (after heart disease) by the year 2020, according to the World Health Organization.
.,:: ,., -C;,f, oun,. ' iiõ~fõ~~,~~.:~iõ1~,:.;;;,, ,i:;;l-~ompds of he present invention can be used in combination with various lrnown drugs. For examples, compounds of the present invention can be used with one or more of the drugs currently available that can relieve the symptoms of depression. They include, for example, monoamine oxidase inhibitors (MAOIs) such as Nardil or Moclobemide (Manerix), tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine (Prozac), paroxetine (Paxil), escitalopram (Lexapro), and sertraline (Zoloft), norepinephrine reuptake inhibitors such as reboxetine (Edronax), and serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine (Effexor) and duloxetine (Cymbalta).
As stated above, histamine H3-receptor antagonists and inverse agonists can be used to treat or prevent attention deficit hyperactivity disorder (ADHD). According to the Diagnostic and Statistical Manual of Mental Disorders-IV-TR, ADHD is a developmental disorder that arises in childhood, in most cases before the age of 7 years, is characterized by developmentally inappropriate levels of inattention and/or hyperactive-impulsive behavior, and results in impairment in, one or more major life activities, such as family, peer, educational, occupational, social, or adaptive functioning. ADHD can also be diagnosed in adulthood.
The first-line medications used to treat ADHD are mostly stimulants, which work by stimulating the areas of the brain responsible for focus, attention, and impulse control. The use of stimulants to treat a syndrome often characterized by hyperactivity is sometimes referred to as a paradoxical effect, but there is no real paradox in that stimulants activate brain inhibitory and self-organizing mechanisms permitting the individual to have greater self-regulation. The stimulants used include, for example, methylphenidate (sold as Ritalin, Ritalin SR and Ritalin LA), Metadate, Metadate ER, Metadate CD, Concerta, Focalin, Focalin XR or Methylin. The stimulants also include, for example, amphetamines such dextroamphetamine , sold as Dexedrine, Dexedrine Spansules, Adderall, and Adderall XR, a trade name for a mixture of dextroamphetamine and laevoamphetamine salts, methamphetamine sold as Desoxyn, bupropion, a dopamine and norepinephrine reuptake inhibitor, marketed under the brand name Wellbutrin. A non-stimulant medication to treat ADHD is Atomoxetine (sold as Strattera) a norepinephrine reuptake inhibitor. Other drugs sometimes used for ADHD
include, for example, benzphetamine, Provigil/Alertec/modafinil and clonidine. Recently it has been reported that in a rat pup model for ADHD, a histamine H3-receptor antagonist was at least as effective as methylphenidate (Ritalin) (Hancock and Fox in Milestones in Drug Therapy, ed.
Buccafusco, 2003). Compounds of the present invention can be used in combination with various known drugs. For examples, compounds of the present invention can be used with one or more of the drugs used to treat ADHD and related disorders.
As stated above, histanzine H3-receptor antagonists and inverse agonists can be used to treat or prevent schizophrenia. Schizophrenia is a psychiatric diagnosis that describes a mental disorder characterized by impairments in the perception or expression of reality and by L.,lf~~ ,: ,.j~, :.
"'signi::ficarit socia ( I or occupationaj dysfunction. A person experiencing untreated schizophrenia is typically characterized as demonstrating disorganized thinlcing, and as experiencing delusions or auditory hallucinations. Although the disorder is primarily thought to affect cognition, it can also contribute to chronic problems with behavior and emotion. Schizophrenia is often described in terms of "positive" and "negative" symptoms. Positive symptoms include delusions, auditory hallucinations and thought disorder, and are typically regarded as manifestations of psychosis. Negative symptoms are so named because they are considered to be the loss or absence of normal traits or abilities, and include features such as flat, blunted or constricted affect and emotion, poverty of speech and lack of motivation. Some models of schizophrenia include formal thought disorder and planning difficulties in a third group, a "disorganization syndrome."
The first line pharmacological therapy for schizophrenia is usually the use of antipsychotic medication. Antipsychotic drugs are only thought to provide symptomatic relief from the positive symptoms of psychosis. The newer atypical antipsychotic medications (such as clozapine, risperidone, olanzapine, quetiapine, ziprasidone and aripiprazole) are usually preferred over older typical antipsychotic medications (such as chlorpromazine and haloperidol) due to their favorable side-effect profile. While the atypical antipsychotics are associated with less extra pyramidal side-effects and tardive dyskinesia than the conventional antipsychotics, some of the agents in this class (especially olanzapine and clozapine) appear to be associated with metabolic side effects such as weight gain, hyperglycemia and hypertriglyceridemia that must be considered when choosing appropriate pharmacotherapy.
Histamine H3-receptor antagonists or inverse agonists can be used to treat obesity (Hancock, Curr. Opin. Iravestig. Drugs 2003, 4, 1190-1197). The role of neuronal histamine in food intake has been established for many years and neuronal histamine release and/or signalling has been implicated in the anorectic actions of known mediators in the feeding cycle such as leptin, amylin and bombesin. In the brain, the H3-receptor is implicated in the regulation of histamine release in the hypothalamus. Moreover, in situ hybridization studies have revealed histamine H3-receptor mRNA expression in rat brown adipose tissue, indicating a role in the regulation of thermogenesis (Karlstedt et al., Mol. Cell.
Neurosci. 2003, 24, 614-622).
Furthermore, histamine H3-receptor antagonists have been investigated in various preclinical models of obesity and have shown to be effective in reducing food intake, reducing weight, and decreasing total body fat in mice (Hancock, et al. Eur. J. Pharmacol. 2004, 487, 183-197). The most common drugs used for the treatment of obesity are sibutramine (Meridia) and orlistat (Xenical), both of which have limited effectiveness and significant side effects. Therefore, novel anti-obesity agents, such as histamine H3-receptor antagonists or inverse agonists, are needed.
l .. f ~~'istamine H3-receptor antagonists or inverse agonists can also be used to treat upper airway allergic responses (U.S. Pat. Nos. 5,217,986; 5,352,707 and 5,869,479) including allergic rhinitis and nasal congestion. Allergic rhinitis is a frequently occurring chronic disease that affects a large number of people. Recent analysis of histamine H3-receptor expression in the periphery by quantitative PCR revealed that H3-receptor mRNA is abundantly expressed in human nasal mucosa (Varty et al. Eur. J. Plaarmacol. 2004, 484, 83-89). In addition, in a cat model of nasal decongestion, a combination of histamine H3-receptor antagonists with the H1 receptor antagonist chlorpheniramine resulted in significant nasal decongestion without the hypertensive effect seen with adrenergic agonists. (McLeod et al. Am. J.
Rhiraol. 1999, 13, 391-399). Thus, histamine H3-receptor antagonists or inverse agonists can be used alone or in combination with H1 receptor blockage for the treatment of allergic rhinitis and nasal congestion.

Compounds of the present invention described herein may be used in combination with modafinil (Provigil) for the treatment of H3-associated disorders such as, cognitive disorders, epilepsy, brain trauma, depression, obesity, motion sickness and vertigo, disorders of sleep and wakefulness such as narcolepsy, shift-work syndrome, drowsiness as a side effect from a medication, maintenance of vigilance to aid in completion of tasks and the like, cataplexy, hypersomnia, somnolence syndrome, jet lag, sleep apnea and the like, attention deficit hyperactivity disorder (ADHD), schizophrenia, allergies, allergic responses in the upper airway, allergic rhinitis, nasal congestion, dementia, Alzheimet's disease and the like.
PHARMACEUTICAL COMPOSITIONS
A further aspect of the present invention pertains to pharmaceutical compositions comprising one or more compounds as described herein and one or more pharmaceutically acceptable carriers. Some embodiments pertain to pharmaceutical compositions comprising a compound of the present invention and a pharmaceutically acceptable carrier.
Some embodiments of the present invention include a method of producing a pharmaceutical composition comprising admixing at least one compound according to any of the compound embodiments disclosed herein and a pharmaceutically acceptable carrier.
Formulations may be prepared by any suitable method, typically by uniformly mixing the active compound(s) with liquids or finely divided solid carriers, or both, in the required proportions, and then, if necessary, forming the resulting mixture into a desired shape.
Conventional excipients, such as binding agents, fillers, acceptable wetting agents, tabletting lubricants, and disintegrants may be used in tablets and capsules for oral administration. Liquid preparations for oral administration may be in the form of solutions, emulsions, aqueous or oily suspensions, and syrups. Alternatively, the oral preparations may be in the form of dry powder that can be reconstituted with water or another suitable liquid vehicle tF (k. il.,~l.,'iii iks ~~e before use. A~c~itional additives such as suspending or emulsifying agents, non-aqueous vehicles (including edible oils), preservatives, and flavorings and colorants may be added to the liquid preparations. Parenteral dosage forms may be prepared by dissolving the compound of the invention in a suitable liquid vehicle and filter sterilizing the solution before filling and sealing- an appropriate vial or ampule. These are just a few examples of the many appropriate methods well known in the art for preparing dosage forms.
A compound of the present invention can be formulated into pharmaceutical compositions using techniques well known to those in the art. Suitable pharmaceutically-acceptable carriers, outside those mentioned herein, are known in the art; for example, see Remington, The Science and Practice of Pharmacy, 20th Edition, 2000, Lippincott Williams &
Wilkins, (Editors: Gennaro, A. R., et al.).
While it is possible that, for use in the prophylaxis or treatment, a compound of the invention may, in an alternative use, be administered as a raw or pure chemical, it is preferable however to present the compound or active ingredient as a pharmaceutical formulation or composition further comprising a pharmaceutically acceptable carrier.
The invention thus further provides pharmaceutical formulations comprising a compound of the invention or a pharmaceutically acceptable salt or derivative thereof together with one or more pharmaceutically acceptable carriers thereof and/or prophylactic ingredients.
The carrier(s) must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not overly deleterious to the recipient thereof.
Pharmaceutical formulations include those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, sub-cutaneous and intravenous) administration or in a form suitable for administration by inhalation, insufflation or by a transdermal patch. Transdermal patches dispense a drug at a controlled rate by presenting the drug for absorption in an efficient manner with a minimum of degradation of the drug. Typically, transdermal patches comprise an impermeable backing layer, a single pressixre sensitive adhesive and a removable protective layer with a release liner. One of ordinary slcill in the art will understand and appreciate the techniques appropriate for manufacturing a desired efficacious transdermal patch based upon the needs of the artisan.
The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical formulations and unit dosages thereof, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, gels or capsules filled with the same, all for oral use, in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use. Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such dos fl,~ll Es.,aI i~,,.~i Il;::i~ ;" u,~~:,~~,:EE,:-~õ!l <<'' s~= lI
umt age fo s rm may conta:in any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.
For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient.
Examples of such dosage units are capsules, tablets, powders, granules or a suspension, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binders such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators such as corn starch, potato starch or sodium carboxymethyl-cellulose; and with lubricants such as talc or magnesium stearate. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable pharmaceutically acceptable carrier.
Compounds of the present invention or a solvate or physiologically functional derivative thereof can be used as active ingredients in pharmaceutical compositions, specifically as H3 receptor modulators. By the ternz "active ingredient" is defined in the context of a "pharmaceutical composition" and is intended to mean a component of a pharmaceutical composition that provides the primary pharmacological effect, as opposed to an "inactive ingredient" which would generally be recognized as providing no pharmaceutical benefit.
The dose when using the compounds of the present invention can vary within wide limits, and as is customary and is known to the physician, it is to be tailored to the individual conditions in each individual case. It depends, for example, on the nature and severity of the illness to be treated, on the condition of the patient, on the compound employed or on whether an acute or chronic disease state is treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention.
Representative doses of the present invention include, but not limited to, about 0.001 mg to about 5000 mg, about 0.001 mg to about 2500 mg, about 0.001 mg to about 1000 mg, 0.001 mg to about 500 mg, 0.001 mg to about 250 mg, about 0.001 mg to 100 mg, about 0.001 mg to about 50 mg, and about 0.001 mg to about 25 mg. Multiple doses may be administered during the day, especially when relatively large amounts are deemed to be needed, for example 2, 3 or 4, doses. Depending on the individual and as deemed appropriate from the patient's physician or care-giver it may be necessary to deviate upward or downward from the doses described herein.
The amount of active ingredient, or an active salt or derivative thereof, required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the patient and will ultimately be at the discretion of the attendant physician or clinician. In general, one skilled in the art understands how to extrapolate in vivo data obtained in a model system, 'typica~7yan animal model, to., another, such as a human. In some circumstances, these extrapolations may merely be based on the weight of the animal model in comparison to another, such as a mammal, preferably a human, however, more often, these extrapolations are not simply based on weights, but rather incorporate a variety of factors.
Representative factors include the type, age, weight, sex, diet and medical condition of the patient, the severity of the disease, the route of administration, pharmacological considerations such as the activity, efficacy, pharmacolcinetic and toxicology profiles of the particular compound employed, whether a drug delivery system is utilized, on whether an acute or chronic disease state is being treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention and as part of a drug combination. The dosage regimen for treating a disease condition with the compounds and/or compositions of this invention is selected in accordance with a variety factors as cited above.
Thus, the actual dosage regimen employed may vary widely and therefore may deviate from a preferred dosage regimen and one skilled in the art will recognize that dosage and dosage regimen outside these typical ranges can be tested and, where appropriate, may be used in the methods of this invention.
The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day.
The sub-dose itself may be fiu-ther divided, e.g., into a number of discrete loosely spaced administrations. The daily dose can be divided, especially when relatively large amounts are administered as deemed appropriate, into several, for example 2, 3 or 4, part administrations. If appropriate, depending on individual behavior, it may be necessary to deviate upward or downward from the daily dose indicated.
The compounds of the present invention can be administrated in a wide variety of oral and parenteral dosage forms. It will be obvious to those skilled in the art that the following dosage forms may comprise, as the active component, either a compound of the invention or a pharmaceutically acceptable salt of a compound of the invention.
For preparing pharmaceutical compositions from the compounds of the present invention, the selection of a suitable pharmaceutically acceptable carrier can be either solid, liquid or a mixture of both. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.
In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.
In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted to the desire shape and size.
l"1ie powaers and tablets may contain varying percentage amounts of the active compound. A representative amount in a powder or tablet may contain from 0.5 to about 90 percent of the active compound; however, an artisan would know when amounts outside of this range are necessary. Suitable carriers for powders and tablets are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like.
The tenn "preparation" is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.
For preparing suppositories, a low melting wax, such as an admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.
Liquid form preparations include solutions, suspensions, and emulsions, for example, _ 20 water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution.
Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
The compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The pharmaceutical compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents.
Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sten ...If ;;"
le solid or ~y ..
lyophi~izatior from solution, for constitution with a suitable vehicle, e.g.
sterile, pyrogen-free water, before use.
Aqueous formulations suitable for oral use can be prepared by dissolving or suspending the active component in water and adding suitable colorants, flavors, stabilizing and thiclcening agents, as desired.

Aqueous suspensions suitable for oral use can be made-by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well known suspending agents.
Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.
For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch.
Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing agents, dispersing agents, suspending agents, thickening agents, or coloring agents.
Formulations suitable for topical administration in the mouth include lozenges comprising active agent in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.
Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomizing spray pump.
Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurized pack with a suitable propellant. If the compounds of the present invention or pharmaceutical compositions comprising them are administered as aerosols, for example as nasal aerosols or by inhalation, this can be carried out, for example, using a spray, a nebulizer, a pump nebulizer, an inhalation apparatus, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administration of the compounds of the present invention as an aerosol can be prepared by processes well-known to the person skilled in the art. For their preparation, for example, solutions or dispersions of the compounds of the present invention in water, water/alcohol mixtures or ...~!' ii~~~~ ".,i{ l.,i( ,, ~~.,!l..uõ!!..-t.lC..:,,G ,~;iill sul~abl'e sa~ine solutions can be employed using customary additives, for example benzyl alcohol or other suitable preservatives, absorption enhancers for increasing the bioavailability, solubilizers, dispersants and others, and, if appropriate, customary propellants, for example include carbon dioxide, CFCs, such as, dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane; and the like. The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.
In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of microns or less. Such a particle size may be obtained by means known in the art, for 10 example by micronization. When desired, formulations adapted to give sustained release of the active ingredient may be employed. -Alternatively the active ingredients may be provided in the form of a dry powder, for example, a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP).
Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler.
The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.
Tablets or capsules for oral administration and liquids for intravenous administration are preferred compositions.
The compounds according to the invention may optionally exist as pharmaceutically acceptable salts including pharmaceutically acceptable acid addition salts prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids.
Representative acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethenesulfonic, dichloroacetic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfiric, tartaric, oxalic, p-toluenesulfonic and the like, such as those pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science, 66, 2 (1977); incorporated herein by reference in its entirety.

The acid addition salts may be obtained as the direct products of compound synthesis.
In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate ., acid,, and4 , 't, e saTt isolate~ by evaporating the solvent or otherwise separating the salt and solvent.
The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.
Compounds of the present invention can be converted to "pro-drugs." The term "pro-drugs" refers to compounds that have been modified with specific chemical groups known in the art and when administered into an individual these groups undergo biotransformation to give the parent compound. Pro-drugs can thus be viewed as compounds of the invention containing one or more specialized non-toxic protective groups used in a transient manner to alter or to eliminate a property of the compound. In one general aspect, the "pro-drug"
approach is utilized to facilitate oral absorption. A thorough discussion is provided in T. Higuchi and V. Stella, "Pro-drugs as Novel Delivery Systems," Vol. 14 of the A.C.S. Symposium Series;
and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are hereby incorporated by reference in their entirety.

Some embodiments of the present invention include a method of producing a pharmaceutical composition for "combination-therapy" comprising admixing at least one compound according to any of the compound embodiments disclosed herein, together with at least one known pharmaceutical agent as described herein and a pharmaceutically acceptable carrier.

It is noted that when the H3 receptor modulators are utilized as active ingredients in a pharmaceutical composition, these are not intended for use only in humans, but in other non-human mammals as well. Indeed, recent advances in the area of animal health-care mandate that consideration be given for the use of active agents, such as H3 receptor modulators, for the treatment of a H3-associated disease or disorder in domestic animals (e.g., cats and dogs) and in other domestic animals (e.g., such as cows, chickens, fish, etc.). Those of ordinary skill in the art are readily credited with understanding the utility of such compounds in such settings.
OTHER UTILITIES
Another object of the present invention relates to radio-labeled compounds of the present invention that would be useful not only in radio-imaging but also in assays, both in vitro and in vivo, for localizing and quantitating the H3 receptor in tissue samples, including human, and for identifying H3 receptor ligands by inhibition binding of a radio-labeled compound. It is a further object of this invention to develop novel H3 receptor assays of which comprise such radio-labeled compounds.

For example, for in vitro H3 receptor labeling and competition assays, compounds that incorporate 3H,1~C, 12 Br,125I , 131I, 35S or will generally be most useful.

For radio-imaging applications lICa 18Fa 125Ia 123Ia 124Ia a 131I 75Br, 76Br or '7Br will generallY be most useful.
- It is understood that a "radio-labeled aa or "labeled compound" is a compound of Formula (Ta) that has incorporated at least one radionuclide; in some embodiments the radionuclide is selected from the group consisting of 3H,14C, 125I , 35S and 82 Br.
Certain isotopically-labeled compounds of the present invention are useful in compound and/or substrate tissue distribution assays. In some embodiments the radionuclide 3H and/or 14C
isotopes are useful in these studies. Further, substitution with heavier isotopes such as deuterium (i.e., ?H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labeled compounds of the present invention can generally be prepared by following procedures analogous to those disclosed in the Schemes supra and Examples infra, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent. Other synthetic methods that are useful are discussed irr.fra. Moreover, it should be understood that all of the atoms represented in the compounds of the invention can be either the most commonly occurring isotope of such atoms or a scarcer radio-isotope or nonradioactive isotope.
Synthetic methods for incorporating radio-isotopes into organic compounds are applicable to compounds of the invention and are well known in the art. These synthetic methods, for example, incorporating activity levels of tritium into target molecules, are as follows:
A. Catalytic Reduction with Tritium Gas - This procedure normally yields high specific activity products and requires halogenated or unsaturated precursors.
B. Reduction with Sodium Borohydride [3H] - This procedure is rather inexpensive and requires precursors containing reducible functional groups such as aldehydes, ketones, lactones, esters, and the like.
C. Reduction with Lithium Aluminum Hydride [3H ]- This procedure offers products at almost theoretical specific activities. It also requires precursors containing reducible functional groups such as aldehydes, ketones, lactones, esters, and the like.

. . . .. .. . . . .
D. ~rrtium as xposure Labeling - This procedure involves exposing precursors containing exchangeable protons to tritium gas in the presence of a suitable catalyst.
E. N-Methylation using 1Vlethyl Iodide [3H] - This procedure is usually employed to prepare 0-methyl or N-methyl (3H) products by treating appropriate precursors with high specific activity methyl iodide (H). This method in general allows for higher specific activity, such as for example, about 70-90 Ci/mmol.
Synthetic methods for incorporating activity levels of 125I into target molecules include:
A. Sandmeyer and like reactions - This procedure transforms an aryl or heteroaryl amine into a diazonium salt, such as a tetrafluoroborate salt, and subsequently to 125I labeled compound using Na125I. A represented procedure was reported by Zhu, D.-G. and co-workers in J. Org. Chem. 2002, 67, 943-948.
B. Ortho 125Iodination of phenols - This procedure allows for the incorporation of 12sI
at the ortho position of a phenol as reported by Collier, T. L. and co-workers in J. Labeled Cornpd. Radiopharna. 1999, 42, S264-S266.
C. Aryl and heteroaryl bromide exchange with125I - This method is generally a two step process. The first step is the conversion of the aryl or heteroaryl bromide to the corresponding tri-alkyltin intermediate using for example, a Pd catalyzed reaction [i.e.
Pd(Ph3P)4] or through an aryl or heteroaryl lithium, in the presence of a tri-alkyltinhalide or hexaalkylditin [e.g., (CH3)3SnSn(CH3)3). A represented procedure was reported by Bas, M.-D.
and co-workers in J. Labeled Compd. Radiopharm. 2001, 44, S280-S282.
A radio-labeled H3 receptor compound of Formula (Ia) can be used in a screening assay to identify/evaluate compounds. In general terms, a newly synthesized or identified compound (i.e., test compound) can be evaluated for its ability to reduce binding of the "radio-labeled compound of Formula (Ia)" to the H3 receptor. Accordingly, the ability of a test compound to compete with the "radio-labeled compound of Formula (la)" for the binding to the H3 receptor directly correlates to its binding affinity.
The labeled compounds of the present invention bind to the H3 receptor. In one embodiment the labeled compound has an IC50 less than about 500 M, in another embodiment the labeled compound has an IC50 less than about 100 M, in yet another embodiment the labeled compound has an IC50 less than about 10 M, in yet another embodiment the labeled compound has an IC50 less than about 1 gM, and in still yet another embodiment the labeled inhibitor has an IC50 less than about 0.1 M.
Other uses of the disclosed receptors and methods will become apparent to those in the art based upon, iizter alia, a review of this disclosure.

The histamine receptor binding assay was conducted using standard laboratory procedures as described below. A crude membrane fraction was prepared from whole rat brain cortex using a polytron to homogenize the tissue followed by differential centrifugation in a HEPES-based buffer containing protease inhibitors. Membranes where frozen at -80 C until needed. Frozen membranes were thawed and resuspended in ice-cold assay buffer consisting of 50mM TRIS containing 5mM EDTA (pH=7.4). 50 micrograms ( g) of membrane protein was added to each well of a 96-well assay plate along with test compound and [3H]-N-a-methyl-histamine (1 nanomolar (nM) final assay concentration). Imetit was used as an assay positive control at varying concentrations. The plate was incubated for 30 minutes at room temperature.
The assay was terminated by rapid filtration through a 96-well glass fiber filtration plate (GF/C) using a cell harvester (Perkin-Elmer). Captured membranes where washed three times with cold assay buffer and plates were dried at 50 C. 35 microliters ( L) of scintillation cocktail was added to each well and nlembrane-bound radioactivity was recorded using a TopCount 96-well plate scintillation counter (Perkin-Elmer).

A ~a1e Sprague-Dawley rats (225-350g) (Harlan, San Diego, CA) were housed two to three per cage and maintained in a humidity- (30-70%) and temperature-(20-22 C) controlled facility on a 12 hr:12 hr light/dark cycle (lights on at 6:30 A.M.) with free access to food (Harlan-Teldad Western Res., Orange, CA, Rodent Diet 8604) and water.
Rats were allowed at least three days of habituation to the animal facility before testing.
Procedure: Rats were placed into individual cages with wire grid bottoms, with free access to water and no food. After 90min of habituation, rats were injected with vehicle or test compound. 30-60min later (depending on PK/route of test compound), water was removed, and vehicle or R-cx methyl-histamine dihydrochloride was injected (20mg/kg salt, SC, 1cc/kg dissolved in water). 10min later, water was returned to cages. Water intake over 20min was then measured.
Data analysis: RAMH-induced drinking was confirmed by comparison of vehicle+vehicle group versus vehicle+RAMH group. % Inhibition of RAMH-induced drinking was calculated for each individual animal as follows: [1-(D-V)/(R-V)]*100 where D = the individual animal's water intake, V = the mean water intake of the vehicle+vehicle group, and R
= the mean water intake of the vehicle+R.ANIII group. Mean SEM % inhibition for test compound groups was then obtained from the % inhibition values of individual animals.

Rats were allowed at least three days of habituation to the animal facility before surgery.
Procedures:
Rats were anaesthetized with a ketamine/xylazine mixture, and surgically prepared for EEG and EMG recording. After 2-3 weeks of post-surgical recovery, rats were habituated to polypropylene test cages for at least three days. On test days, the rats were placed in the test chambers and habituated overnight. At 10 am the next day, the rats were administered the test compound, connected to the recording apparatus, and placed back into the test chambers for 3 h.
Data analysis EEG and EMG data were digitized and stored in 10 s epochs over the three hour test period. These data were then visually scored, and each 10 s epoch characterized as either a non-REM sleep, REM sleep, or waking episode. Total wake time over the three hour period was calculated for each rat after either vehicle administration or test compound.
Percent increase in wakefulness was then derived for each rat.
