STATEMENT OF RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCHNot applicable.
BACKGROUND OF THE INVENTIONNeurotransmitters such as histamine, serotonin, dopamine and norepinephrine mediate a large number of processes in the central nervous system (CNS) as well as outside the CNS. Abnormal neurotransmitter levels are associated with a wide variety of diseases and conditions including, but not limited to, Alzheimer's disease, Parkinson's Disease, autism, ADD, ADHD, Guillain-Barré syndrome, mild cognitive impairment, schizophrenia (such as cognitive impairment associated with schizophrenia (CIAS), positive symptoms, disorganized symptoms, and negative symptoms of schizophrenia), anxiety, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, diabetic neuropathy, fibromyalgia, bipolar disorders, psychosis, depression, attention-deficit disorder (ADD), attention-deficit hyperactivity disorder (ADHD) and a variety of allergic diseases. Compounds that modulate these neurotransmitters may be useful therapeutics.
Histamine receptors belong to the superfamily of G protein-coupled seven transmembrane proteins. G protein-coupled receptors constitute one of the major signal transduction systems in eukaryotic cells. Coding sequences for these receptors, in those regions believed to contribute to the agonist-antagonist binding site, are strongly conserved across mammalian species. Histamine receptors are found in most peripheral tissue and within the central nervous system. Compounds capable of modulating a histamine receptor may find use in therapy, e.g., histamine antagonists may find use as antihistamines.
Dimebon is a known anti-histamine drug that has also been characterized as a neuroprotective agent useful to treat, inter alia, neurodegenerative diseases. Dimebon has been shown to inhibit the death of brain cells (neurons) in preclinical models of Alzheimer's disease and Huntington's disease, making it a novel potential treatment for these and other neurodegenerative diseases. In addition, dimebon has been shown to improve the mitochondrial function of cells in the setting of cellular stress with very high potency. For example, dimebon treatment improved mitochondrial function and increased the number of surviving cells after treatment with the cell toxin ionomycin in a dose dependent fashion. Dimebon has also been shown to promote neurite outgrowth and neurogenesis, processes important in the formation of new and/or enhanced neuronal cell connections, and evidence of dimebon's potential for use in additional diseases or conditions. See, e.g., U.S. Pat. Nos. 6,187,785 and 7,071,206 and PCT Patent Application Nos. PCT/US2004/041081, PCT/US2007/020483, PCT/US2006/039077, PCT/US2008/077090, PCT/US2007/020516, PCT/US2007/022645, PCT/US2007/002117, PCT/US2008/006667, PCT/US2007/024626, PCT/US2008/009357, PCT/US2007/024623, PCT/US2008/008121, and PCT/US2009/032065. Hydrogenated pyrido[4,3-b]indoles and uses thereof have been disclosed in PCT Patent Application Nos. PCT/US2008/081390, PCT/US2009/032065 and PCT/US2009/038142. Hydrogenated pyrido[3,4-b]indoles and uses thereof have been described in PCT/US2009/038138. All references disclosed herein and throughout, such as publications, patents, patent applications and published patent applications, are incorporated herein by reference in their entireties.
Although dimebon holds great promise as a drug for the treatment of neurodegenerative diseases and/or diseases in which neurite outgrowth and/or neurogenesis may be implicated in therapy, there remains a need for new and alternative therapies for the treatment of such diseases or conditions. In addition, there remains a need for new and alternative antihistamine drugs, preferably ones in which side-effects such as drowsiness are reduced or eliminated. Compounds that exhibit enhanced and/or more desirable properties than dimebon (e.g., superior safety and efficacy) may find particular use in the treatment of at least those indications for which dimebon is believed to be advantageous. Further, compounds that exhibit a different therapeutic profile than dimebon as determined, e.g. by in vitro and/or in vivo assays, may find use in additional diseases and conditions.

As used herein, “delaying” development of a disease or condition means to defer, hinder, slow, retard, stabilize and/or postpone development of the disease or condition. This delay can be of varying lengths of time, depending on the history of the disease and/or individual being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the individual does not develop the disease or condition. For example, a method that “delays” development of Alzheimer's disease is a method that reduces probability of disease development in a given time frame and/or reduces extent of the disease in a given time frame, when compared to not using the method. Such comparisons are typically based on clinical studies, using a statistically significant number of subjects. For example, Alzheimer's disease development can be detected using standard clinical techniques, such as routine neurological examination, patient interview, neuroimaging, detecting alterations of levels of specific proteins in the serum or cerebrospinal fluid (e.g., amyloid peptides and Tau), computerized tomography (CT) or magnetic resonance imaging (MRI). Similar techniques are known in the art for other diseases and conditions. Development may also refer to disease progression that may be initially undetectable and includes occurrence, recurrence and onset.
As used herein, an “at risk” individual is an individual who is at risk of developing a cognitive disorder, a psychotic disorder, a neurotransmitter-mediated disorder and/or a neuronal disorder that can be treated with a compound of the invention. An individual “at risk” may or may not have a detectable disease or condition, and may or may not have displayed detectable disease prior to the treatment methods described herein. “At risk” denotes that an individual has one or more so-called risk factors, which are measurable parameters that correlate with development of a disease or condition and are known in the art. An individual having one or more of these risk factors has a higher probability of developing the disease or condition than an individual without these risk factor(s). These risk factors include, but are not limited to, age, sex, race, diet, history of previous disease, presence of precursor disease, genetic (i.e., hereditary) considerations, and environmental exposure. For example, individuals at risk for Alzheimer's disease include, e.g., those having relatives who have experienced this disease and those whose risk is determined by analysis of genetic or biochemical markers. Genetic markers of risk for Alzheimer's disease include mutations in the APP gene, particularly mutations at position 717 and positions 670 and 671 referred to as the Hardy and Swedish mutations, respectively (Hardy, Trends Neurosci., 20:154-9, 1997). Other markers of risk are mutations in the presenilin genes (e.g., PS1 or PS2), ApoE4 alleles, family history of Alzheimer's disease, hypercholesterolemia and/or atherosclerosis. Other such factors are known in the art for other diseases and conditions.
As used herein, the term “pro-cognitive” includes but is not limited to an improvement of one or more mental processes such as memory, attention, perception and/or thinking, which may be assessed by methods known in the art.
As used herein, the term “neurotrophic” effects includes but is not limited to effects that enhance neuron function such as growth, survival and/or neurotransmitter synthesis.
As used herein, the term “cognitive disorders” refers to and intends diseases and conditions that are believed to involve or be associated with or do involve or are associated with progressive loss of structure and/or function of neurons, including death of neurons, and where a central feature of the disorder may be the impairment of cognition (e.g., memory, attention, perception and/or thinking). These disorders include pathogen-induced cognitive dysfunction, e.g. HIV associated cognitive dysfunction and Lyme disease associated cognitive dysfunction. Examples of cognitive disorders include Alzheimer's Disease, Huntington's Disease, Parkinson's Disease, schizophrenia, amyotrophic lateral sclerosis (ALS), autism, ADD, ADHD, mild cognitive impairment (MCI), stroke, traumatic brain injury (TBI) and age-associated memory impairment (AAMI).
As used herein, the term “psychotic disorders” refers to and intends mental diseases or conditions that are believed to cause or do cause abnormal thinking and perceptions. Psychotic disorders are characterized by a loss of reality which may be accompanied by delusions, hallucinations (perceptions in a conscious and awake state in the absence of external stimuli which have qualities of real perception, in that they are vivid, substantial, and located in external objective space), personality changes and/or disorganized thinking. Other common symptoms include unusual or bizarre behavior, as well as difficulty with social interaction and impairment in carrying out the activities of daily living. Exemplary psychotic disorders are schizophrenia, bipolar disorders, psychosis, anxiety and depression.
As used herein, the term “neurotransmitter-mediated disorders” refers to and intends diseases or conditions that are believed to involve or be associated with or do involve or are associated with abnormal levels of neurotransmitters such as histamine, serotonin, dopamine, norepinephrine or impaired function of aminergic G protein-coupled receptors. Exemplary neurotransmitter-mediated disorders include spinal cord injury, diabetic neuropathy, allergic diseases and diseases involving geroprotective activity such as age-associated hair loss (alopecia), age-associated weight loss and age-associated vision disturbances (cataracts). Abnormal neurotransmitter levels are associated with a wide variety of diseases and conditions including, but not limited, to Alzheimer's disease, Parkinson's Disease, autism, ADD, ADHD, Guillain-Barré syndrome, mild cognitive impairment, schizophrenia, anxiety, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, diabetic neuropathy, fibromyalgia, bipolar disorders, psychosis, depression and a variety of allergic diseases.
As used herein, the term “neuronal disorders” refers to and intends diseases or conditions that are believed to involve, or be associated with, or do involve or are associated with neuronal cell death and/or impaired neuronal function or decreased neuronal function. Exemplary neuronal indications include neurodegenerative diseases and disorders such as Alzheimer's disease, Huntington's disease, amyotrophic lateral sclerosis (ALS), Parkinson's disease, canine cognitive dysfunction syndrome (CCDS), Lewy body disease, Menkes disease, Wilson disease, Creutzfeldt-Jakob disease, Fahr disease, an acute or chronic disorder involving cerebral circulation, such as ischemic or hemorrhagic stroke or other cerebral hemorrhagic insult, age-associated memory impairment (AAMI), mild cognitive impairment (MCI), injury-related mild cognitive impairment (MCI), post-concussion syndrome, post-traumatic stress disorder, adjuvant chemotherapy, traumatic brain injury (TBI), neuronal death mediated ocular disorder, macular degeneration, age-related macular degeneration, autism, including autism spectrum disorder, Asperger syndrome, and Rett syndrome, an avulsion injury, a spinal cord injury, myasthenia gravis, Guillain-Barré syndrome, multiple sclerosis, diabetic neuropathy, fibromyalgia, neuropathy associated with spinal cord injury, schizophrenia, bipolar disorder, psychosis, anxiety or depression.
As used herein, the term “neuron” represents a cell of ectodermal embryonic origin derived from any part of the nervous system of an animal. Neurons express well-characterized neuron-specific markers, including neurofilament proteins, NeuN (Neuronal Nuclei marker), MAP2, and class III tubulin. Included as neurons are, for example, hippocampal, cortical, midbrain dopaminergic, spinal motor, sensory, sympathetic, septal cholinergic, and cerebellar neurons.
As used herein, the term “neurite outgrowth” or “neurite activation” refers to the extension of existing neuronal processes (e.g., axons and dendrites) and the growth or sprouting of new neuronal processes (e.g., axons and dendrites). Neurite outgrowth or neurite activation may alter neural connectivity, resulting in the establishment of new synapses or the remodeling of existing synapses.
As used herein, the term “neurogenesis” refers to the generation of new nerve cells from undifferentiated neuronal progenitor cells, also known as multipotential neuronal stem cells. Neurogenesis actively produces new neurons, astrocytes, glia, Schwann cells, oligodendrocytes and/or other neural lineages. Much neurogenesis occurs early in human development, though it continues later in life, particularly in certain localized regions of the adult brain.
As used herein, the term “neural connectivity” refers to the number, type, and quality of connections (“synapses”) between neurons in an organism. Synapses form between neurons, between neurons and muscles (a “neuromuscular junction”), and between neurons and other biological structures, including internal organs, endocrine glands, and the like. Synapses are specialized structures by which neurons transmit chemical or electrical signals to each other and to non-neuronal cells, muscles, tissues, and organs. Compounds that affect neural connectivity may do so by establishing new synapses (e.g., by neurite outgrowth or neurite activation) or by altering or remodeling existing synapses. Synaptic remodeling refers to changes in the quality, intensity or type of signal transmitted at particular synapses.
As used herein, the term “neuropathy” refers to a disorder characterized by altered function and/or structure of motor, sensory, and autonomic neurons of the nervous system, initiated or caused by a primary lesion or other dysfunction of the nervous system. Patterns of peripheral neuropathy include polyneuropathy, mononeuropathy, mononeuritis multiplex and autonomic neuropathy. The most common form is (symmetrical) peripheral polyneuropathy, which mainly affects the feet and legs. A radiculopathy involves spinal nerve roots, but if peripheral nerves are also involved the term radiculoneuropathy is used. The form of neuropathy may be further broken down by cause, or the size of predominant fiber involvement, e.g. large fiber or small fiber peripheral neuropathy. Central neuropathic pain can occur in spinal cord injury, multiple sclerosis, and some strokes, as well as fibromyalgia. Neuropathy may be associated with varying combinations of weakness, autonomic changes and sensory changes. Loss of muscle bulk or fasciculations, a particular fine twitching of muscle may also be seen. Sensory symptoms encompass loss of sensation and “positive” phenomena including pain. Neuropathies are associated with a variety of disorders, including diabetes (e.g., diabetic neuropathy), fibromyalgia, multiple sclerosis, and herpes zoster infection, as well as with spinal cord injury and other types of nerve damage.
As used herein, the term “Alzheimer's disease” refers to a degenerative brain disorder characterized clinically by progressive memory deficits, confusion, behavioral problems, inability to care for oneself, gradual physical deterioration and, ultimately, death. Histologically, the disease is characterized by neuritic plaques, found primarily in the association cortex, limbic system and basal ganglia. The major constituent of these plaques is amyloid beta peptide (Aβ), which is the cleavage product of beta amyloid precursor protein (βAPP or APP). APP is a type I transmembrane glycoprotein that contains a large ectopic N-terminal domain, a transmembrane domain and a small cytoplasmic C-terminal tail. Alternative splicing of the transcript of the single APP gene on chromosome 21 results in several isoforms that differ in the number of amino acids. Aβ appears to have a central role in the neuropathology of Alzheimer's disease. Familial forms of the disease have been linked to mutations in APP and the presenilin genes (Tanzi et al., 1996, Neurobiol. Dis., 3:159-168; Hardy, 1996, Ann. Med., 28:255-258). Diseased-linked mutations in these genes result in increased production of the 42-amino acid form of Aβ, the predominant form found in amyloid plaques. Mitochondrial dysfunction has also been reported to be an important component of Alzheimer's disease (Bubber et al., Mitochondrial abnormalities in Alzheimer brain: Mechanistic Implications, Ann Neurol., 2005, 57(5), 695-703; Wang et al., Insights into amyloid-β-induced mitochondrial dysfunction in Alzheimer disease, Free Radical Biology & Medicine, 2007, 43, 1569-1573; Swerdlow et al., Mitochondria in Alzheimer's disease, Int. Rev. Neurobiol., 2002, 53, 341-385; and Reddy et al., Are mitochondria critical in the pathogenesis of Alzheimer's disease?, Brain Res Rev. 2005, 49(3), 618-32). It has been proposed that mitochondrial dysfunction has a causal relationship with neuronal function (including neurotransmitter synthesis and secretion) and viability. Compounds which stabilize mitochondria may therefore have a beneficial impact on Alzheimer's patients.
As used herein, the term “Huntington's disease” refers to a fatal neurological disorder characterized clinically by symptoms such as involuntary movements, cognition impairment or loss of cognitive function and a wide spectrum of behavioral disorders. Common motor symptoms associated with Huntington's disease include chorea (involuntary writhing and spasming), clumsiness, and progressive loss of the abilities to walk, speak (e.g., exhibiting slurred speech) and swallow. Other symptoms of Huntington's disease can include cognitive symptoms such as loss of intellectual speed, attention and short-term memory and/or behavioral symptoms that can span the range of changes in personality, depression, irritability, emotional outbursts and apathy. Clinical symptoms typically appear in the fourth or fifth decade of life. Huntington's disease is a devastating and often protracted illness, with death usually occurring approximately 10-20 years after the onset of symptoms. Huntington's disease is inherited through a mutated or abnormal gene encoding an abnormal protein called the mutant huntingtin protein; the mutated huntingtin protein produces neuronal degeneration in many different regions of the brain. The degeneration focuses on neurons located in the basal ganglia, structures deep within the brain that control many important functions including coordinating movement, and on neurons on the outer surface of the brain or cortex, which controls thought, perception and memory.
“Amyotrophic lateral sclerosis” or “ALS” is used herein to denote a progressive neurodegenerative disease that affects upper motor neurons (motor neurons in the brain) and/or lower motor neurons (motor neurons in the spinal cord) and results in motor neuron death. As used herein, the term “ALS” includes all of the classifications of ALS known in the art, including, but not limited to classical ALS (typically affecting both lower and upper motor neurons), Primary Lateral Sclerosis (PLS, typically affecting only the upper motor neurons), Progressive Bulbar Palsy (PBP or Bulbar Onset, a version of ALS that typically begins with difficulties swallowing, chewing and speaking), Progressive Muscular Atrophy (PMA, typically affecting only the lower motor neurons) and familial ALS (a genetic version of ALS).
The term “Parkinson's disease” as used herein refers to any medical condition wherein an individual experiences one or more symptoms associated with Parkinson's disease, such as without limitation one or more of the following symptoms: rest tremor, cogwheel rigidity, bradykinesia, postural reflex impairment, symptoms having good response to 1-dopa treatment, the absence of prominent oculomotor palsy, cerebellar or pyramidal signs, amyotrophy, dyspraxia and/or dysphasia. In a specific embodiment, the present invention is utilized for the treatment of a dopaminergic dysfunction-related disorder. In a specific embodiment, the individual with Parkinson's disease has a mutation or polymorphism in a synuclein, parkin or NURR1 nucleic acid that is associated with Parkinson's disease. In one embodiment, the individual with Parkinson's disease has defective or decreased expression of a nucleic acid or a mutation in a nucleic acid that regulates the development and/or survival of dopaminergic neurons.
As used herein, the term “canine cognitive dysfunction syndrome,” or “CCDS” refers to an age-related deterioration of mental function typified by multiple cognitive impairments that affect an afflicted canine's ability to function normally. The decline in cognitive ability that is associated with CCDS cannot be completely attributed to a general medical condition such as neoplasia, infection, sensory impairment, or organ failure. Diagnosis of CCDS in canines, such as dogs, is generally a diagnosis of exclusion, based on thorough behavior and medical histories and the presence of clinical symptoms of CCDS that are unrelated to other disease processes. Owner observation of age-related changes in behavior is a practical means used to detect the possible onset of CCDS in aging domestic dogs. A number of laboratory cognitive tasks may be used to help diagnose CCDS, while blood counts, chemistry panels and urinalysis can be used to rule out other underlying diseases that could mimic the clinical symptoms of CCDS. Symptoms of CCDS include memory loss, which in domestic dogs may be manifested by disorientation and/or confusion, decreased or altered interaction with family members and/or greeting behavior, changes in sleep-wake cycle, decreased activity level, and loss of house training or frequent, inappropriate elimination. A canine suffering from CCDS may exhibit one or more of the following clinical or behavioral symptoms: decreased appetite, decreased awareness of surroundings, decreased ability to recognize familiar places, people or other animals, decreased hearing, decreased ability to climb up and down stairs, decreased tolerance to being alone, development of compulsive behavior or repetitive behaviors or habits, circling, tremors or shaking, disorientation, decreased activity level, abnormal sleep wake cycles, loss of house training, decreased or altered responsiveness to family members, and decreased or altered greeting behavior. CCDS can dramatically affect the health and well-being of an afflicted canine. Moreover, the companionship offered by a pet with CCDS can become less rewarding as the severity of the disease increases and its symptoms become more severe.
As used herein, the term “age-associated memory impairment” or “AAMI” refers to a condition that may be identified as GDS stage 2 on the global deterioration scale (GDS) (Reisberg, et al. (1982) Am. J. Psychiatry 139: 1136-1139) which differentiates the aging process and progressive degenerative dementia in seven major stages. The first stage of the GDS is one in which individuals at any age have neither subjective complaints of cognitive impairment nor objective evidence of impairment. These GDS stage 1 individuals are considered normal. The second stage of the GDS applies to those generally elderly persons who complain of memory and cognitive functioning difficulties such as not recalling names as well as they could five or ten years previously or not recalling where they have placed things as well as they could five or ten years previously. These subjective complaints appear to be very common in otherwise normal elderly individuals. AAMI refers to persons in GDS stage 2, who may differ neurophysiologically from elderly persons who are normal and free of subjective complaints, i.e., GDS stage 1. For example, AAMI subjects have been found to have more electrophysiologic slowing on a computer analyzed EEG than GDS stage 1 elderly persons (Prichep, John, Ferris, Reisberg, et al., (1994) Neurobiol. Aging 15: 85-90).
As used herein, the term “mild cognitive impairment” or “MC1” refers to a type of cognitive disorder characterized by a more pronounced deterioration in cognitive functions than is typical for normal age-related decline. As a result, elderly or aged patients with MCI have greater than normal difficulty performing complex daily tasks and learning, but without the inability to perform normal social, everyday, and/or professional functions typical of patients with Alzheimer's disease, or other similar neurodegenerative disorders eventually resulting in dementia. MCI is characterized by subtle, clinically manifest deficits in cognition, memory, and functioning, amongst other impairments, which are not of sufficient magnitude to fulfill criteria for diagnosis of Alzheimer's disease or other dementia. MCI also encompasses injury-related MCI, defined herein as cognitive impairment resulting from certain types of injury, such as nerve injury (i.e., battlefield injuries, including post-concussion syndrome, and the like), neurotoxic treatment (i.e., adjuvant chemotherapy resulting in “chemo brain” and the like), and tissue damage resulting from physical injury or other neurodegeneration, which is separate and distinct from mild cognitive impairment resulting from stroke, ischemia, hemorrhagic insult, blunt force trauma, and the like.
As used herein, the term “traumatic brain injury” or “TBI” refers to a brain injury caused by a sudden trauma, such as a blow or jolt or a penetrating head injury, which disrupts the function or damages the brain. Symptoms of TBI can range from mild, moderate to severe and can significantly affect many cognitive (deficits of language and communication, information processing, memory, and perceptual skills), physical (ambulation, balance, coordination, fine motor skills, strength, and endurance), and psychological skills.
“Neuronal death mediated ocular disease” intends an ocular disease in which death of the neuron is implicated in whole or in part. The disease may involve death of photoreceptors. The disease may involve retinal cell death. The disease may involve ocular nerve death by apoptosis. Particular neuronal death mediated ocular diseases include but are not limited to macular degeneration, glaucoma, retinitis pigmentosa, congenital stationary night blindness (Oguchi disease), childhood onset severe retinal dystrophy, Leber congenital amaurosis, Bardet-Biedle syndrome, Usher syndrome, blindness from an optic neuropathy, Leber's hereditary optic neuropathy, color blindness and Hansen-Larson-Berg syndrome.
As used herein, the term “macular degeneration” includes all forms and classifications of macular degeneration known in the art, including, but not limited to diseases that are characterized by a progressive loss of central vision associated with abnormalities of Bruch's membrane, the choroid, the neural retina and/or the retinal pigment epithelium. The term thus encompasses disorders such as age-related macular degeneration (ARMD) as well as rarer, earlier-onset dystrophies that in some cases can be detected in the first decade of life. Other maculopathies include North Carolina macular dystrophy, Sorsby's fundus dystrophy, Stargardt's disease, pattern dystrophy, Best disease, and Malattia Leventinese.
As used herein, the term “autism” refers to a brain development disorder that impairs social interaction and communication and causes restricted and repetitive behavior, typically appearing during infancy or early childhood. The cognitive and behavioral defects are thought to result in part from altered neural connectivity. Autism encompasses related disorders sometimes referred to as “autism spectrum disorder,” as well as Asperger syndrome and Rett syndrome.
As used herein, the term “nerve injury” or “nerve damage” refers to physical damage to nerves, such as avulsion injury (i.e., where a nerve or nerves have been torn or ripped) or spinal cord injury (i.e., damage to white matter or myelinated fiber tracts that carry sensation and motor signals to and from the brain). Spinal cord injury can occur from many causes, including physical trauma (i.e., car accidents, sports injuries, and the like), tumors impinging on the spinal column, developmental disorders, such as spina bifida, and the like.
As used herein, the term “myasthenia gravis” or “MG” refers to a non-cognitive neuromuscular disorder caused by immune-mediated loss of acetylcholine receptors at neuromuscular junctions of skeletal muscle. Clinically, MG typically appears first as occasional muscle weakness in approximately two-thirds of patients, most commonly in the extraocular muscles. These initial symptoms eventually worsen, producing drooping eyelids (ptosis) and/or double vision (diplopia), often causing the patient to seek medical attention. Eventually, many patients develop general muscular weakness that may fluctuate weekly, daily, or even more frequently. Generalized MG often affects muscles that control facial expression, chewing, talking, swallowing, and breathing; before recent advances in treatment, respiratory failure was the most common cause of death.
As used herein, the term “Guillain-Barré syndrome” refers to a non-cognitive disorder in which the body's immune system attacks part of the peripheral nervous system. The first symptoms of this disorder include varying degrees of weakness or tingling sensations in the legs. In many instances the weakness and abnormal sensations spread to the arms and upper body. These symptoms can increase in intensity until certain muscles cannot be used at all and, when severe, the patient is almost totally paralyzed. In these cases the disorder is life threatening—potentially interfering with breathing and, at times, with blood pressure or heart rate—and is considered a medical emergency. Most patients, however, recover from even the most severe cases of Guillain-Barré syndrome, although some continue to have a certain degree of weakness.
As used herein, the term “multiple sclerosis” or “MS” refers to an autoimmune condition in which the immune system attacks the central nervous system (CNS), leading to demyelination of neurons. It may cause numerous symptoms, many of which are non-cognitive, and often progresses to physical disability. MS affects the areas of the brain and spinal cord known as the white matter. White matter cells carry signals between the grey matter areas, where the processing is done, and the rest of the body. More specifically, MS destroys oligodendrocytes which are the cells responsible for creating and maintaining a fatty layer, known as the myelin sheath, which helps the neurons carry electrical signals. MS results in a thinning or complete loss of myelin and, less frequently, the cutting (transection) of the neuron's extensions or axons. When the myelin is lost, the neurons can no longer effectively conduct their electrical signals. Almost any neurological symptom can accompany the disease. MS takes several forms, with new symptoms occurring either in discrete attacks (relapsing forms) or slowly accumulating over time (progressive forms). Most people are first diagnosed with relapsing-remitting MS but develop secondary-progressive MS (SPMS) after a number of years. Between attacks, symptoms may go away completely, but permanent neurological problems often persist, especially as the disease advances.
As used herein, the term “schizophrenia” refers to a chronic, mental disorder characterized by one or more positive symptoms (e.g., delusions and hallucinations) and/or negative symptoms (e.g., blunted emotions and lack of interest) and/or disorganized symptoms (e.g., disorganized thinking and speech or disorganized perception and behavior). Schizophrenia as used herein includes all forms and classifications of schizophrenia known in the art, including, but not limited to catatonic type, hebephrenic type, disorganized type, paranoid type, residual type or undifferentiated type schizophrenia and deficit syndrome and/or those described in American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Washington D.C., 2000 or in International Statistical Classification of Diseases and Related Health Problems, or otherwise known to those of skill in the art.
“Cognitive impairment associated with schizophrenia” or “CIAS” includes neuropsychological deficits in attention, working memory, verbal learning, and problem solving. These deficits are believed to be linked to impairment in functional status (e.g., social behavior, work performance, and activities of daily living).
As used herein “geroprotective activity” or “geroprotector” means a biological activity that slows down ageing and/or prolongs life and/or increases or improves the quality of life via a decrease in the amount and/or the level of intensity of pathologies or conditions that are not life-threatening but are associated with the aging process and which are typical for elderly people. Pathologies or conditions that are not life-threatening but are associated with the aging process include such pathologies or conditions as loss of sight (cataract), deterioration of the dermatohairy integument (alopecia), and an age-associated decrease in weight due to the death of muscular and/or fatty cells.
As used herein, attention-deficit hyperactivity disorder (ADHD) is the most common child neuropsychiatric condition present in school-aged children, affecting about 5-8% of this population. ADHD refers to a chronic disorder that initially manifests in childhood and is characterized by hyperactivity, impulsivity, and/or inattention. ADHD is characterized by persistent patterns of inattention and/or impulsivity-hyperactivity that are much more extreme than is observed in individuals at the same developmental level or stage. There is considerable evidence, from family and twin studies, that ADHD has a significant genetic component. This disorder is thought to be due to an interaction of environmental and genetic factors. ADHD includes all known types of ADHD. For example, Diagnostic & Statistical Manual for Mental Disorders (DSM-IV) identifies three subtypes of ADHD: (1) ADHD, Combined Type which is characterized by both inattention and hyperactivity-impulsivity symptoms; 2. ADHD, Predominantly Inattentive Type which is characterized by inattention but not hyperactivity-impulsivity symptoms; and 3. ADHD, Predominantly Hyperactive-Impulsive Type which is characterized by Hyperactivity-impulsivity but not inattention symptoms.
As used herein, attention-deficit disorder (ADD) refers to a disorder in processing neural stimuli that is characterized by distractibility and impulsivity that can result in inability to control behavior and can impair an individual's social, academic, or occupational function and development. ADD may be diagnosed by known methods, which may include observing behavior and diagnostic interview techniques.
As used herein “allergic disease” refers to a disorder of the immune system which is characterized by excessive activation of mast cells and basophils and production of IgE immunoglobulins, resulting in an extreme inflammatory response. It represents a form of hypersensitivity to an environmental substance known as allergen and is an acquired disease. Common allergic reactions include eczema, hives, hay fever, asthma, food allergies, and reactions to the venom of stinging insects such as wasps and bees. Allergic reactions are accompanied by an excessive release of histamines, and can thus be treated with antihistaminic agents.
As used herein, by “combination therapy” is meant a therapy that includes two or more different compounds. Thus, in one aspect, a combination therapy comprising a compound detailed herein and anther compound is provided. In some variations, the combination therapy optionally includes one or more pharmaceutically acceptable carriers or excipients, non-pharmaceutically active compounds, and/or inert substances. In various embodiments, treatment with a combination therapy may result in an additive or even synergistic (e.g., greater than additive) result compared to administration of a single compound of the invention alone. In some embodiments, a lower amount of each compound is used as part of a combination therapy compared to the amount generally used for individual therapy. Preferably, the same or greater therapeutic benefit is achieved using a combination therapy than by using any of the individual compounds alone. In some embodiments, the same or greater therapeutic benefit is achieved using a smaller amount (e.g., a lower dose or a less frequent dosing schedule) of a compound in a combination therapy than the amount generally used for individual compound or therapy. Preferably, the use of a small amount of compound results in a reduction in the number, severity, frequency, and/or duration of one or more side-effects associated with the compound.
As used herein, the term “effective amount” intends such amount of a compound of the invention which in combination with its parameters of efficacy and toxicity, as well as based on the knowledge of the practicing specialist should be effective in a given therapeutic form. As is understood in the art, an effective amount may be in one or more doses, i.e., a single dose or multiple doses may be required to achieve the desired treatment endpoint. An effective amount may be considered in the context of administering one or more therapeutic agents, and a single agent may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable or beneficial result may be or is achieved. Suitable doses of any of the co-administered compounds may optionally be lowered due to the combined action (e.g., additive or synergistic effects) of the compounds.
As used herein, “unit dosage form” refers to physically discrete units, suitable as unit dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Unit dosage forms may contain a single or a combination therapy.
As used herein, the term “controlled release” refers to a drug-containing formulation or fraction thereof in which release of the drug is not immediate, i.e., with a “controlled release” formulation, administration does not result in immediate release of the drug into an absorption pool. The term encompasses depot formulations designed to gradually release the drug compound over an extended period of time. Controlled release formulations can include a wide variety of drug delivery systems, generally involving mixing the drug compound with carriers, polymers or other compounds having the desired release characteristics (e.g., pH-dependent or non-pH-dependent solubility, different degrees of water solubility, and the like) and formulating the mixture according to the desired route of delivery (e.g., coated capsules, implantable reservoirs, injectable solutions containing biodegradable capsules, and the like).
As used herein, by “pharmaceutically acceptable” or “pharmacologically acceptable” is meant a material that is not biologically or otherwise undesirable, e.g., the material may be incorporated into a pharmaceutical composition administered to a patient without causing any significant undesirable biological effects or interacting in a deleterious manner with any of the other components of the composition in which it is contained. Pharmaceutically acceptable carriers or excipients have preferably met the required standards of toxicological and manufacturing testing and/or are included on the Inactive Ingredient Guide prepared by the U.S. Food and Drug administration.
“Pharmaceutically acceptable salts” are those salts which retain at least some of the biological activity of the free (non-salt) compound and which can be administered as drugs or pharmaceuticals to an individual. Such salts, for example, include: (1) acid addition salts, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with organic acids such as acetic acid, oxalic acid, propionic acid, succinic acid, maleic acid, tartaric acid and the like; (2) salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base. Acceptable organic bases include ethanolamine, diethanolamine, triethanolamine and the like. Acceptable inorganic bases include aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, and the like. Further examples of pharmaceutically acceptable salts include those listed in Berge et al., Pharmaceutical Salts, J. Pharm. Sci. 1977 January; 66(1):1-19. Pharmaceutically acceptable salts can be prepared in situ in the manufacturing process, or by separately reacting a purified compound of the invention in its free acid or base form with a suitable organic or inorganic base or acid, respectively, and isolating the salt thus formed during subsequent purification. It should be understood that a reference to a pharmaceutically acceptable salt includes the solvent addition forms or crystal forms thereof, particularly solvates or polymorphs. Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and are often formed during the process of crystallization. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Polymorphs include the different crystal packing arrangements of the same elemental composition of a compound. Polymorphs usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Various factors such as the recrystallization solvent, rate of crystallization, and storage temperature may cause a single crystal form to dominate.

Strikingly, it has been discovered that compounds included in the invention that contain a substituted vinyl moiety, such as methylvinyl, exhibit a lower binding affinity to H1 as compared to their unsubstituted vinyl counterparts. Thus, it is believed that substituted vinyl moieties, such as methylvinyl, may be responsible for reduced H1 affinity.
Compounds that exhibit affinity for the histamine receptor H1 may induce undesirable side effects, such as metabolic syndrome, diabetes type 2, weight gain, hyperlipidemia, hyperglycemia, hypertension and drowsiness (Kroeze et al., Neuropsychopharmacology (2003) 28, 519-526). The number and extent of undesirable side effects increases with increasing affinity for the H1 receptor. Thus, in one aspect, compounds of the formulae herein display reduced, low or no affinity to histamine receptor H1. Compounds with low affinity to H1 are those compounds which display less than about 80% inhibition of binding of a ligand to H1. Inhibition of binding of a ligand to H1 for all variations detailed herein is determined by a suitable assay known in the art such as the assay described herein. In some variations, compounds of the formulae herein inhibit binding of a ligand to H1 by less than about any of 80%, 75%, 70%, 65%, 60% 55% and 50%. In one variation, compounds of the formulae herein inhibit binding of a ligand to H1 by between about 50% to about 80%.

Dose-Dependent Therapy (DDT)Dose dependent therapy refers to the concept that a single molecule may be used for different indications depending on the dose at which it is administered. It has been shown that compounds included in the invention exert pro-cognitive effects (where in one aspect pro-cognitive effects are achieved by reducing one or more symptoms associated with impaired cognition) when administered at low dose, whereas at high dose, these compounds induce both pro-cognitive and anti-psychotic effects (where in one aspect anti-psychotic effects are achieved by reducing one or more symptoms associated with a psychotic disorder). These compounds are further referred to as Dose-Dependent Therapy compounds (DDT compounds). When administered at high dose, DDT compounds in one aspect show fewer and/or lesser side-effects such as, e.g., extrapyramidal syndrome (EPS), as compared to other anti-psychotics, such as anti-psychotics which are not 5-HT2A receptor modulators. It is believed that EPS is caused, at least in part, by high D2 receptor occupancy, the effect of which can be counteracted by compounds displaying a high affinity to the serotonin receptor 5-HT2A. EPS can be determined using various scales known in the art such as the Abnormal Involuntary Movement Scale (AIMS), Barnes Akathisia Rating Scale (BARS), Simpson-Angus Rating Scale (SARS), Extrapyramidal Symptoms Rating Scale (ESRS) and the Extrapyramidal Symptoms Rating Scale-Abbreviated (ESRS-A).

Method of Determining a Dose/TreatmentThe present invention further encompasses methods of determining a suitable or optimal dose of a DDT compound to either (i) achieve pro-cognitive effects alone or (ii) achieve both pro-cognitive effects and anti-psychotic effects in an individual in need thereof. In one aspect, a suitable dose is determined by measuring the percentage of D2 occupancy and adjusting an individual's dosage in response thereto. In one variation, dosage is increased to achieve anti-psychotic effects if D2 occupancy is less than 65% as determined by methods known in the art such as PET. In another variation, dosage is increased to achieve anti-psychotic effects if D2 occupancy is less than any one of 65%, 60%, 55%, and 50%. In a further variation, dosage is reduced to achieve pro-cognitive and not anti-psychotic effects if D2 occupancy is at least 65%. In yet another variation, dosage is reduced to achieve pro-cognitive and not anti-psychotic effects if D2 occupancy is at greater than any one of 65%, 70%, 75%, 80% and 90%. In a further variation, dosage is reduced to achieve pro-cognitive and no significant anti-psychotic effects if D2 occupancy is greater than 65%. One indication of at least 65% D2 occupancy or greater than any one of 65%, 70%, 75%, 80% and 90% D2 occupancy is the reduction in the number or severity of one or more symptoms associated with a psychotic disorder.
In another aspect, a suitable dose is determined by assessing pro-cognitive and/or anti-psychotic effects in an individual and adjusting an individual's dosage in response thereto. For example, in one variation, an individual's dosage is increased from a first dosage to a higher, second dosage, in order to achieve anti-psychotic effects at the second dosage level, if it is determined that the first dosage does not induce anti-psychotic effects in the individual, as may be assessed by suitable test and/or scales known in the art. In another variation, dosage is reduced from a first dosage to a lower, second dosage wherein the second dosage still achieves anti-psychotic effects but reduces side effects as compared to the first dosage. Side effects may be determined by suitable tests and/or scales known in the art. In another variation, dosage is decreased from a first dosage to a lower, second dosage, in order to achieve pro-cognitive and not anti-psychotic effects. In another variation, dosage is decreased from a first dosage to a lower, second dosage, in order to achieve pro-cognitive and not anti-psychotic effects and wherein the dosage induces fewer or lesser side effects than the first dosage. Thus, in yet another variation, dosage is reduced to a minimum dosage which still achieves pro-cognitive effects but reduces side-effects as determined by suitable tests and/or scales.
In one aspect, an individual's therapy is monitored as set forth above for a period of time, such as one week, two weeks, three weeks, one month, two months, three months, four months, five months, 6 months or more (such as throughout the course of an individual's therapy), to adjust an individual's dosage level as needed. As such, individualized therapy as detailed herein provides for methods of measuring therapeutic parameters and adjusting dosage in response thereto in order to achieve an optimal dosage amount according to an individual's initial and continued response to therapy.

Example B11 Increase of Neurite Outgrowth of Neurons that were Cultured with Compounds of the Invention Neurite Outgrowth in Cortical NeuronsCompounds are tested to determine their ability to stimulate neurite outgrowth of cortical neurons. Standard methods are used to isolate cortical neurons. For the isolation of primary rat cortical neurons, the fetal brain from a pregnant rat at 17 days of gestation is prepared in Leibovitz's medium (L15; Gibco). The cortex is dissected out, and the meninges are removed. Trypsin (Gibco) is used to dissociate cortical C with DNAse I. The cells are triturated for 30 min. with a pipette in Dulbecco's Modified Eagle Media (“DMEM”; Gibco) with 10% Fetal Bovine Serum (“FBS”) (Gibco) and centrifuged at 350×g for 10 min. at RT. The cells are suspended in Neurobasal medium supplemented with 2% B27 (Gibco) and 0.5 mM L-glutamine (Gibco). The cells are maintained at 30,000 cells per well of poly-L-lysine coated plates at 37° C. in 5% CO2-95% air atmosphere. After adhesion, a vehicle control or compounds of the invention are added at different concentrations to the medium. BDNF (50 ng/mL) is used as a positive control for neurite growth. After treatment, cultures are washed in phosphate-buffered saline (“PBS”; Gibco) and fixed in glutaraldehyde 2.5% in PBS. Cells are fixed after 3 days growth. Several pictures (˜80) of cells with neurites are taken per condition with a camera. The length measurements are made by analysis of the pictures using software from Image-Pro Plus (France). The results are expressed as mean (s.e.m.). Statistical analysis of the data is performed using one way analysis of variance (ANOVA).
Neurite Outgrowth in Rat Mixed Cortical CulturesCortical mixed cultures are prepared from E18 Wistar rat embryos. The cortices are dissected out and the tissue was cut to small pieces. The cells are separated by 15-min. incubation with DNase and papain. The cells are collected by centrifugation (1500 rpm, 5 min.). The tissue is triturated with a pipette and the cells are plated using the micro-islet protocol (20 000 cells in 25 μl medium) on poly-L-lysine coated 48 wells, in MEM supplemented with 2 mM glutamine, 0.1 μg/mL gentamicin, 10% heat-inactivated fetal bovine serum (FBS-HI) and 10% heat-inactivated horse serum (HS-HI). After the cells has attached to the well, 250 μl medium is added to the wells. Four hours after plating the medium is changed to fresh medium (MEM with supplements and 5% HS-HI) containing test compound at 0.5, 5 and 50 nM concentrations. As positive controls BDNF (50, 100 and/or 150 ng/mL), and/or NGF (50 ng/mL and/or 100 ng/mL) are used. After 2 days in vitro, the cell's conditioned media are collected from plates before fixing the cells. The media samples are centrifuged 13 000 rpm 3 min. to get rid of cell debris. The samples are stored at −20 C for later analysis. Cells are formaldehyde-fixed and processed for immunocytochemistry. BDNF levels in the conditioned media are determined with a BDNF ELISA using the manufacturers (Promega, BDNF Emax® ImmunoAssay System, catalog number: G7610) instructions.
The cultures are fixed with 4% formaldehyde in 0.01 M PBS for 30 min. and washed once with PBS. The fixed cells are first permeabilized and non-specific binding is blocked by a 30-min. incubation with blocking buffer containing 1% bovine serum albumin and 0.3% Triton X-100 in PBS. Rabbit anti-MAP-2 (dilution 1:1000, AB5622, Chemicon, in blocking buffer) is used as a primary antibody. The cells are incubated with the primary antibody for 48 h at +4° C., washed with PBS and incubated with secondary antibody goat anti-rabbit IgG conjugated to Alexa Fluor568 (1:200, A11036, Molecular Probes) for 2 h at RT. The immunopositive cells are visualized by a fluorescence microscope equipped with appropriate filter set, and documented by a high resolution image capturing. The number of cells per field (4 field per well) are counted, and the neurite outgrowth is quantified using Image Pro Plus software.
The number of wells per compound concentration used is 6 (n=6). All data are presented as mean±standard deviation (SD) or standard error of mean (SEM), and differences are considered to be statistically significant at the p<0.05 level. Statistical analysis is performed using StatsDirect statistical software. Differences between group means are analyzed by using 1-way-ANOVA followed by Dunnet's test (comparison to the vehicle treated group).
Example B12 Use of an In Vivo Model to Evaluate the Ability of Compounds to Enhance Cognition, Learning and Memory in Scopolamine Treated RatsThe two-trial object recognition paradigm developed by Ennaceur and Delacour in the rat is used as a model of episodic/short term memory. Ennaceur, A., and Delacour, J. (1988), Behav. Brain Res. 31:47-59. The paradigm is based on spontaneous exploratory activity of rodents and does not involve rule learning or reinforcement. The novel object recognition paradigm is sensitive to the effects of ageing and cholinergic dysfunction. See, e.g., Scali, C., et al., (1994), Neurosci. Letts. 170:117-120; and Bartolini, L., et al., (1996), Biochem. Behav. 53:277-283.
Male Sprague-Dawley rats between six and seven weeks old, weighing between 220-300 grams are obtained from Centre d'Elevage (Rue Janvier, B. P. 55, Le Genest-Saint-Isle 53940, France). The animals are housed in groups of 2 to 4 in polypropylene cages (with a floor area of 1032 cm2) under standard conditions: at RT (22±2° C.), under a 12 hour light/12 hour dark cycle, with food and water provided ad libitum. Animals are permitted to acclimate to environmental conditions for at least 5 days before the experiment begins, and are numbered on their tails with indelible marker.
The experimental arena is a square wooden box (60 cm×60 cm×40 cm) painted dark blue, with 15 cm×15 cm black squares under a clear plexiglass floor. The arena and objects placed inside the arena are cleaned with water between each trial to eliminate any odor trails left by rats. The arena is placed in a dark room illuminated only by halogen lamps directed towards the ceiling in order to produce a uniformly dim light in the box of approximately 60 lux. The day before testing, animals are allowed to freely explore the experimental arena for three min. in the presence of two objects (habituation). Animals to be tested are placed in the experimental room at least 30 min. before testing.
Novel object recognition test is comprised of two trials separated by an interval of 120 min. or 24 h. When agents that disrupt memory such as the cholinergic antagonist scopolamine are used an inter-trial interval of 120 min. is preferred. Alternatively a 24 h inter-trial interval is used when studying effect of natural forgetting on novel object recognition task. During the first, or acquisition, trial (T1), rats are placed in the arena, where two identical objects have been previously placed. The time required for each animal to complete 15 seconds of object exploration is determined, with a cut-off time of four min. Exploration is considered to be directing the nose at a distance less than 2 centimeters (“cm”) from the object and/or touching the object. During the second, or testing, trial (T2), one of the objects presented in the first trial is replaced with an unknown or novel object, while the second, familiar object was left in place. Rats are placed back in the arena for three min., and exploration of both objects is determined. Locomotor activity of rats (number of times rats cross grid lines visible under the clear plexiglass floor) is scored for during T1 and T2. At the conclusion of the experiments, the rats are sacrificed by an overdose of pentobarbital given intraperitoneally.
The following parameters are measured as part of the novel object recognition task: (1) time required to achieve 15 seconds of object exploration during T1; (2) locomotor activity during T1 (number of crossed lines); (3) time spent in active exploration of the familiar object during T2 (TFamiliar); (4) time spent in active exploration of the novel object during T2 (TNovel); and (5) locomotor activity during T2 (number of crossed lines). The difference between time spent in active exploration of the novel object during T2 and time spent in active exploration of the familiar object during T2 (δ TNovel−TFamiliar) is evaluated. The % of animals in each group with TNovel−TFamiliar greater than or equal to 5 seconds is also derived; described as % of good learners.
Animals not meeting a minimal level of object exploration are excluded from the study as having naturally low levels of spontaneous exploration. Only rats exploring the objects for at least five seconds (TNovel+TFamiliar>5 seconds) are included in the study.
Animals are randomly assigned to groups of 14. Compounds of the invention and controls are administered to animals the groups as follows: Solutions of compounds are prepared freshly each day at a concentration of 0.25 mg/mL using purified water or saline as vehicle. Donepezil, used as a positive control, and scopolamine are administered simultaneously in a single solution of saline (5 mL/kg) prepared freshly each day. Scopolamine is purchased from Sigma Chemical Co. (Catalog No.S-1875; St. Quentin Fallavier, France) is dissolved in saline to a concentration of 0.06 mg/mL.
Donepezil or its vehicle and scopolamine are administered intraperitoneally 40 min. before the acquisition trial (T1). Compounds or their vehicle are administered by gavage 25 min. before the acquisition trial (T1), i.e., 5 min. after administration of scopolamine. The volume of administration is 5 mL/kg body weight for compounds administered intraperitoneally, and 10 mL/kg for compounds administered orally. Recognition scores and % of good learners for compounds of the invention are determined.

One exemplary model for testing the activity of one or more compounds described herein to treat and/or prevent and/or delay the onset and/or development of schizophrenia employs phencyclidine (PCP), which is administered to the animal (e.g., non-primate (rat) or primate (monkey)), resulting in dysfunctions similar to those seen in schizophrenic humans. See Jentsch et al., 1997, Science 277:953-955 and Piercey et al., 1988, Life Sci. 43(4):375-385). Standard experimental protocols may be employed in this or in other animal models. One protocol involves PCP-induced hyperactivity.
Male mice (various strains, e.g., C57B1/6J) from appropriate vendor (for example, Jackson Laboratories (Bar Harbor, Me.) are used. Mice are received at 6-weeks of age. Upon receipt, mice are assigned unique identification numbers (tail marked) and are group housed with 4 mice/cage in OPTI mouse ventilated cages. All animals remained housed in groups of four during the remainder of the study. All mice are acclimated to the colony room for at least two weeks prior to testing and are subsequently tested at an average age of 8 weeks. During the period of acclimation, mice are examined on a regular basis, handled, and weighed to assure adequate health and suitability. Animals are maintained on a 12/12 light/dark cycle. The room temperature is maintained between 20 and 23° C. with a relative humidity maintained between 30% and 70%. Food and water are provided ad libitum for the duration of the study. In each test, animals are randomly assigned across treatment groups.
The open filed (OF) test assesses locomotor behavior, i.e. to measure mouse locomotor activity at baseline and in response to pharmacological agents. The open field chambers are Plexiglas square chambers (27.3×27.3×20.3 cm; Med Associates Inc., St Albans, Vt.) surrounded by infrared photobeams (16×16×16) to measure horizontal and vertical activity. The analysis is configured to divide the open field into a center and periphery zone such that the infrared photobeams allow measurement of activity in the center and periphery of the field. Distance traveled is measured from horizontal beam breaks as the mouse moved whereas rearing activity is measured from vertical beam breaks.
Mice (10 to 12 animals per treatment group) are brought to the activity experimental room for at least 1 h acclimation to the experimental room conditions prior to testing. Eight animals are tested in each run. Mice are administered vehicle (e.g., 10% DMSO or 5% PEG200 and 1% Tween 80), compound of the invention, clozapine (positive control, 1 mg/kg ip) and placed in the OF chambers for 30 min. following which they are injected with either water or PCP and placed back in the OF chambers for a 60-min. session. At the end of each OF test session the OF chambers are thoroughly cleaned.
PCP Hyperactivity Mouse Model of SchizophreniaThe test compound at the desired dose is dissolved in appropriate vehicle, e.g., 5% PEG200, 1% Tween 80 and administered orally 30 min. prior to PCP injection. Clozapine (1 mg/kg) is dissolved in 10% DMSO and administered i.p. 30 min. prior to PCP injection. PCP (5 mg/kg) is dissolved in sterile injectable saline solution and administered i.p.
Data are analyzed by analysis of variance (ANOVA) followed by post-hoc comparisons with Fisher Tests when appropriate. Baseline activity is measured during the first 30 min. of the test prior to PCP injection. PCP-induced activity is measured during the 60 min. following PCP injection. Statistical outliers that fell above or below 2 standard deviations from the mean are removed from the final analyses. An effect is considered significant if p<0.05. Total distances traveled and total rearing following PCP administration are compared between groups treated with compounds and groups treated with vehicle and positive control clozapine.
Example B14 Use of an In Vivo Model to Determine the Ability of Compounds to Treat, Prevent and/or Delay the Onset and/or the Development of Schizophrenia in Amphetamine Treated AnimalsMale mice (various strains e.g., C57B1/6J) from appropriate supplier (for example Jackson Laboratories, Bar Harbor, Me.) are used. Mice typically are received at 6-weeks of age. Mice are acclimated to the colony room for at least two weeks prior to testing. During the period of acclimation, mice are examined on a regular basis, handled, and weighed to assure adequate health and suitability and maintained on a 12/12 light/dark cycle. The room temperature is maintained between 20 and 23° C. with a relative humidity maintained between 30% and 70%. Food and water are provided ad libitum for the duration of the study. In each test, animals are randomly assigned between treatment groups.
The open field test (OF) is used to assess motor activity. The open field chambers are plexiglas square chambers (e.g., 27.3×27.3×20.3 cm; Med Associates Inc., St Albans, Vt.) surrounded by infrared photobeam sources (16×16×16). The enclosure is configured to split the open field into a center and periphery zone and the photocell beams are set to measure activity in the center and in the periphery of the OF chambers. Horizontal activity (distance traveled) and vertical activity (rearing) are measured from consecutive beam breaks.
On the day of testing, animals are brought to the experimental room for at least 1 h acclimation prior to start of treatment. Animals are administered with vehicle, haloperidol (positive control, 0.1 mg/kg ip) or test compound and placed in the OF. The time of administration of client compound to each animal is recorded. Baseline activity is recorded for 30 min. following which mice receive amphetamine (4 mg/kg) or water and are placed back in the OF chambers for a 60-min. session. At the end of each open field test session the OF chambers are thoroughly cleaned. Typically ten to twelve mice are tested in each group. Test compound doses typically range from 0.01 mg/kg to 60 mg/kg. Data are analyzed by analysis of variance (ANOVA) followed by post-hoc comparisons with Fisher Tests when appropriate. Baseline activity is measured during the first 30 min of the test prior to amphetamine injection. Amphetamine-induced activity is measured during the 60 min following amphetamine injection. Statistical outliers that fall above or below 2 standard deviations from the mean are removed from the final analyses. An effect is considered significant if p<0.05. Total distance traveled and total rearing following amphetamine administration are compared between groups treated with compound and groups treated with vehicle and positive control haloperidol.
Example B15 Use of the In Vivo Conditioned Avoidance Response (CAR) Model to Determine the Ability of Compounds to Treat, Prevent and/or Delay the Onset and/or the Development of SchizophreniaAll currently approved antipsychotic agents (typical and atypical) are known to have the ability to selectively suppress conditioned avoidance response (CAR) behavior in the rat. This evidence makes CAR one of the primary tests to assess antipsychotic activity of novel compounds. Rats (various strains, 2 months of age) are trained and tested in a computer-assisted, two-way active avoidance apparatus (shuttle box). This box consists of two compartments of equal size divided by a stainless steel partition containing an opening of 7×7 cm. Each compartment is equipped with an electrified grid floor made of stainless steel rods spaced 1 cm apart. Rats trained to avoid the foot shock are placed each day in the shuttle box for a 4 min. habituation period followed by 30 trials spaced by inter-trial interval varying at random between 20 and 30 sec. Each trial consists of a 10-sec. stimulus light (conditioned stimulus, CS) followed by a 10-sec. foot shock (unconditioned stimulus, US) in presence of the light presented in the compartment where the rat is located. If the animal leaves the compartment prior to the delivery of the foot shock, the response is considered an avoidance response. If the rat does not change compartment during the 10-sec. light period and during the 10-sec. shock+light period, an escape failure is recorded. This test requires animals to be trained 5 d/week. On each training day, rats are submitted to one training session of 30-trials. Treatment with test compound is initiated only when rats reach an avoidance performance of at least 80% on at least two consecutive training sessions. The test compound is administered orally at various doses and various pre-treatment times (depending upon specific pharmacokinetic properties).
Compounds with antipsychotic profile inhibit conditioned avoidance responses with or without increases in escape failures. Statistical analysis is performed using a Friedman two-way ANOVA by ranks followed by the Wilcoxon matched-pairs signed-ranks test to test each dose of the test compound administered versus vehicle control treated rats.
Example B16 An Animal Model of the Negative Symptoms of Schizophrenia: Subchronic PCP-Induced Social Interaction DeficitsPhencyclidine (PCP) administered to humans as well to experimental animals induces full-spectrum of schizophrenia symptoms, including negative symptoms and cognitive deficits. A major symptom of schizophrenia is considered to be social isolation/withdrawal as part of the cluster of negative symptoms. Subchronic treatment with PCP in rats leads to the development of clear signs of social withdrawal as measured by deficits in the interaction time with a cage intruder rat. Male Sprague Dawley rats (about 150 g, obtained from different vendors, for example Harlan, Ind.) are used in this study. Upon receipt, rats are group housed in OPTI rat ventilated cages. Rats are housed in groups of 2-3 per cage for the remainder of the study. During the period of acclimation, rats are examined on a regular basis, handled, and weighed to assure adequate health and suitability. Rats are maintained on a 12/12 light/dark cycle with the light on at 7:00 a.m. The room temperature is maintained between 20-23° C. with a relative humidity maintained between 30-70%. Food and water are provided ad libitum for the duration of the study. Animals are randomly assigned across treatment groups and balanced by age.
For five days prior to test, rats are injected twice daily with either PCP (2 mg/kg; s.c) or saline (s.c). On day 6 and following a 30 min pretreatment with vehicle, clozapine (2.5 mg/kg ip dissolved in 5% PEG:5% Tween 80) as positive control and test compound at desired dose dissolved in appropriate vehicle, a pair of rats, unfamiliar to each other, receiving the same treatment are placed in a white plexiglas open field arena (24″×17″×8″) and allowed to interact with each other for 6 min. Social interactions (‘SI’) include: sniffing the other rat; grooming the other rat; climbing over or under or around the other rat; following the other rat; or exploring the ano-genital area of the other rat. Passive contact and aggressive contact are not considered a measure of social interaction. The time the rats spent interacting with each other during the 6 min. test is recorded by a trained observer. The social interaction chambers are thoroughly cleaned between the different rats. Data are analyzed by analysis of variance (ANOVA) followed by post-hoc analysis (e.g., Fischer, Dunnett) when appropriate. An effect is considered significant if p<0.05.
Example B17 An Animal Model of Extrapyramidal Syndrome (EPS): Measurement of Catalepsy in the Mouse Bar TestAntipsychotic drugs are known to induce extrapyramidal syndrome (EPS) in animals and in humans. An animal model considered to be predictive of EPS is the mouse bar test, which measures cataleptic responses to pharmacological agents. Male mice (various strains) from appropriate vendor (for example, Jackson Laboratories (Bar Harbor, Me.) are used. Mice are received at 6-weeks of age. Upon receipt, mice are assigned unique identification numbers (tail marked) and are group housed with 4 mice per cage in OPTI mouse ventilated cages. All animals remain housed in groups of four during the remainder of the study. All mice are acclimated to the colony room for at least two weeks prior to testing and are subsequently tested at an average age of 8 weeks. During the period of acclimation, mice are examined on a regular basis, handled, and weighed to assure adequate health and suitability. Animals are maintained on a 12/12 light/dark cycle. The room temperature is maintained between 20-23° C. with a relative humidity maintained between 30-70%. Food and water are provided ad libitum for the duration of the study. In each test, animals are randomly assigned across treatment groups.
In the mouse bar test, the front paws of a mouse are placed on a horizontal bar raised 2″ above a Plexiglas platform and time is recorded for up to 30 sec. per trial. The test ends when the animal's front paws return to the platform or after 30 sec. The test is repeated 3 times and the average of 3 trials is recorded as index of catalepsy. In these studies the typical antipsychotic agent haloperidol (2 mg/kg ip dissolved in 10% DMSO) is used as positive control and induces rigidity and catalepsy as measured by time spent holding on the bar. 30 min. prior to the trial, test compound at desired dose and dissolved in appropriate vehicle is administered PO, vehicle and positive control haloperidol (2 mg.kg ip) are administered to separate groups of mice. Catalepsy responses are measure 30 min., 1 h and 3 h following treatments. A trained observer is measuring time spent holding onto the bar during the 30 sec. trial. Data are analyzed by analysis of variance (ANOVA) followed by post-hoc analysis (e.g., Fischer, Dunnett) when appropriate. An effect is considered significant if p<0.05.
Example B18 An Animal Model to Test the Anxiolytic Effects of Compounds Using the Elevated Plus Maze (EPM) TestThis study may be used to test the anxiolytic properties of compounds detailed herein using the elevated plus maze (EPM) test in C57B1/6J mice.
Male C57B1/6J mice from Jackson Laboratories (Bar Harbor, Me.) are used for the open field study. Mice are received at 6-weeks of age. Upon receipt, mice are assigned unique identification numbers (tail marked) and are group housed with 4 mice/cage in OPTI mouse ventilated cages. All animals remain housed in groups of four during the remainder of the study. All mice are acclimated to the colony room for approximately 2 week prior to testing and are subsequently tested at an average age of 8 weeks of age. During the period of acclimation, mice and rats are examined on a regular basis, handled, and weighed to assure adequate health and suitability. Animals are maintained on a 12 h/12 h light/dark cycle. The room temperature is maintained between 20 and 23° C. with a relative humidity maintained between 30% and 70%. Chow and water are provided ad libitum for the duration of the study. In each test, animals are randomly assigned across treatment groups. All animals are euthanized after the completion of the study.
Compounds may be dissolved in 5% PEG200/H2O and administered orally at a dose volume of 10 mL/kg 30 min prior to test; 2) Diazepam (2.5 mg/kg) is dissolved in 45% hydroxypropyl-β-cyclodextrin and administered orally at a dose volume of 10 mL/kg 30 min prior to test.
The elevated plus maze test assesses anxiety. The maze (Hamilton Kinder) consists of two closed arms (14.5 h×5 w×35 cm length) and two open arms (6 w×35 1 cm) forming a cross, with a square center platform (6×6 cm). All visible surfaces are made of black acrylic. Each arm of the maze is placed on a support column 56 cm above the floor. Antistatic black vinyl curtains (7′ tall) surround the EPM to make a 5′×5″ enclosure. Animals are brought to acclimate to the experimental room at least 1 h before the test. Mice are placed in the center of the elevated plus maze facing the closed arm for a 5-min run. All animals are tested once. The time spent, distance traveled and entries in each arm are automatically recorded by a computer. The EPM is thoroughly cleaned after each mouse.
Data are analyzed using analysis of variance (ANOVA) followed by Fisher's LSD post hoc analysis when appropriate. An effect is considered significant if p<0.05.
