[0003] Areas of disclosure This disclosure describes synaptic vesicle glycoprotein 2A (SV2A) inhibitors as GABA A This disclosure relates to methods, uses, combinations, and pharmaceutical compositions that are useful for treating cognitive impairment and improving cognitive function when used in combination with α5 receptor agonists. In particular, this disclosure is not limited to, but includes, the treatment of cognitive impairment related to central nervous system (CNS) disorders in subjects who need treatment or are at risk of having such conditions, including, but are not limited to, age-related cognitive impairment, mild cognitive impairment (MCI), amnesic MCI (aMCI), age-related memory impairment (AAMI), age-related cognitive decline (ARCD), dementia, Alzheimer's disease (AD), prodromal AD, post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder, amyotrophic lateral sclerosis (ALS), cognitive impairment associated with cancer treatment, intellectual disability, Parkinson's disease (PD), autism, obsessive-compulsive behavior, and subjective addiction, by using SV2A inhibitors in combination with GABA receptor agonists. AThis disclosure relates to use in combination with α5 receptor agonists. The disclosure also provides combinations for use and pharmaceutical compositions for use in the treatment of cognitive impairment and improvement of cognitive function.

[Background technology]

[0004] Background of Disclosure Cognitive abilities may decline as a normal consequence of aging or as a result of central nervous system (CNS) disorders or brain cancer.

[0005] For example, a significant portion of older adults experience cognitive decline beyond what is typical for normal aging. Such age-related loss of cognitive function is clinically characterized by a progressive loss of memory, cognition, reasoning, and judgment. Age-related memory impairment (AAMI), age-related cognitive decline (ARCD), or similar clinical classifications may be associated with such age-related loss of cognitive function. Some estimates suggest that more than 16 million people in the United States alone have AAMI (Barker et al., 1995).

[0006] Cognitive impairment is also associated with other central nervous system (CNS) disorders such as mild cognitive impairment (MCI), dementia, Alzheimer's disease (AD), prodromal AD, post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder (e.g., mania), amyotrophic lateral sclerosis (ALS), cancer treatment-related cognitive impairment, intellectual disability, Parkinson's disease (PD), autism, obsessive-compulsive behavior, and substance addiction. For example, it is estimated that 5.5 to 7 million people over the age of 65 in the United States have MCI (Plassman et al., 2008).

[0007] Therefore, effective treatments are needed for these cognitive impairments, as well as cognitive impairments associated with other central nervous system (CNS) disorders.

[0008] Furthermore, it is necessary to treat cognitive impairments associated with brain cancer or the brain cancer itself in patients requiring treatment. Additionally, it is necessary to treat Parkinson's disease-related mental disorders in patients requiring treatment. [Overview of the project] [Means for solving the problem]

[Brief explanation of the drawing]

[0040] [Figure 1]Figure 1 illustrates the effective plasma level range in aMCI patients based on studies in aged and disabled rats and Phase II studies. The acceptable range target is established based on the effective plasma level range in aged and disabled rats and aMCI patients, i.e., between 1.9 and 4.4 μg / ml. The preferred range target is established based on the effective plasma level range in aMCI patients, i.e., between 2.9 and 4.4 μg / ml.

[0041] [Figure 2] Figure 2 illustrates the effect of levetiracetam administration on spatial memory retention in six aged disabled rats (AIs) in the Maurice Water Maze (MWM) test. Three treatment conditions were used: vehicle control, levetiracetam (5 mg / kg / day), and levetiracetam (10 mg / kg / day). AI rats received one treatment per day before the training trial and trained for two consecutive days. AI rats were tested 24 hours later. Spatial memory retention was measured by the time spent swimming around the target quadrant or target ring in the memory recall trial, 24 hours after two days of training under various treatment conditions. The target quadrant refers to the quadrant of the maze (which is a circular pool) where the escape platform is placed during the training trial. The target ring refers to the exact location of the escape platform during the training trial.

[0042] [Figure 3]Figure 3 illustrates the effect of levetiracetam administration on spatial memory retention in 10 aged disabled rats (AI) in an 8-lane radial maze (RAM) test. Six treatment conditions were used: vehicle control, levetiracetam (1.25 mg / kg), levetiracetam (2.5 mg / kg), levetiracetam (5 mg / kg), levetiracetam (10 mg / kg), and levetiracetam (20 mg / kg). In the RAM task used, there was a 1-hour delay between the presentation of a subset of lanes (5 lanes passable and 3 lanes blocked) and the completion of an 8-lane win-shift task (8 lanes passable). Rats were pre-treated 30–40 minutes before each daily trial with a single drug / control treatment. The number of errors made by rats after the delay was used as a measure of spatial memory retention. An error was defined as a rat entering a run where food had already been retrieved in a component prior to the delay time of the trial, or a rat revisiting a run it had already visited in a session after the delay time. Paired t-tests were used to compare the number of errors between various doses of levetiracetam and vehicle controls.

[Modes for carrying out the invention]

[0096] Detailed explanation of disclosure GABA A Receptor (GABA) AR) is a pentamer aggregate derived from a pool of various subunits (α1-6, β1-3, γ1-3, δ, ε, π, θ) that form Cl-permeable channels activated by the neurotransmitter gamma-aminobutyric acid (GABA). It exhibits a variety of pharmacological effects, including anxiety disorders, epilepsy, insomnia, pre-anesthetic sedation, and muscle relaxation, depending on the GABA. A It is mediated by subtypes.

[0097] Numerous studies have demonstrated that reduced GABA signaling is associated with various CNS disorders that lead to cognitive impairment. For example, some previous studies have shown that in rats with age-related cognitive decline, GABA A It has been demonstrated that the expression of the α5 subunit of the receptor is reduced in the hippocampus (see International Patent Publication WO2007 / 019312). In addition, other studies have shown that GABA A α5-containing GABA, an α5 receptor agonist A Positive allosteric modulators of R have been shown to be useful in treating CNS disorders, cognitive impairments associated with brain cancer, and cognitive impairments associated with brain cancer or Parkinson's disease psychiatry. See, for example, WO2015 / 095783, WO2018 / 130868, WO2016 / 205739, WO2018 / 130869, WO2019 / 246300, and US62 / 950,886 (all of which are incorporated herein by special reference).

[0098] Synaptic vesicle protein-2 (SV2) is a family of synaptic vesicle proteins consisting of three members designated as SV2A, SV2B, and SV2C. SV2A is the most widely distributed family member and is universally expressed in the brain. This protein is an endogenous membrane protein and has low levels of homology (20-30%) to the 12-transmembrane family of bacterial and fungal transporter proteins that transport sugars, citrates, and xenobiotics (Bajjalieh et al., Science, 257: 1271-1273 (1992)). SV2 family proteins are present in brain and endocrine cells, and are also present in all synaptic and endocrine vesicles. SV2 proteins play a vital role in normal synaptic function, as well as in vesicle transport. 2+It has been reported to play a role in the function of the primed vesicle maturation step, which converts to a synaptotagmin-responsive state (Sudhof et al., 2009). The SV2 protein has been reported to enhance the potential for neurotransmitter release by enhancing synaptic currents and maintaining a size of readily releaseable vesicle pools (Custer et al., 2006). Various studies have shown that SV2A inhibitors, compounds that bind to SV2A and reduce synaptic function by decreasing presynaptic vesicle release (see, for example, Noyer et al. 1995, Fuks et al. 2003, Lynch et al. 2004, Gillard et al. 2006, Custer et al., 2006, Smedt et al., 2007, Yang et al., 2007, Meehan, "Levetiracetam has an activity-dependent effect on inhibitory transmission," Epilepsia, 2012 Jan 31, and Example 8 of WO2001 / 62726 (all of which are incorporated herein by special reference)), may be useful in treating cognitive impairment associated with CNS disorders. For example, international patent applications PCT / US2009 / 005647 (publication number WO2010 / 044878), international patent applications PCT / US2011 / 024256 (publication number WO2011 / 100373), international patent applications PCT / US2012 / 024556 (publication number WO2012 / 109491), and international patent applications PCT / US2013 / 070144 (publication number WO2014 / 0785 See also International Patent Application No. 68), International Patent Application PCT / US2014 / 029170 (Publication No. WO2014 / 144663), International Patent Application PCT / US2014 / 029362 (Publication No. WO2014 / 144801), and International Patent Application PCT / US2016 / 033567 (Publication No. WO2016 / 191288) (all of which are incorporated herein by special reference).

[0099] Surprisingly, SV2A inhibitors (e.g., levetiracetam, brivalacetam, or ceretracetam), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs or isomers, and GABA A α5 receptor agonists (e.g., compounds of formula I, II, or IV; compounds 1-740, 1-114 mentioned above; or form A of compound 1, form B of compound 1, form C of compound 1, form E of compound 1, or form F of compound 1), or pharmaceutically acceptable salts thereof, hydrates thereof, solvates thereof, polymorphs thereof, or combinations of their isomers have been found to have synergistic and hyperadditive effects on the treatment of cognitive impairments associated with CNS disorders (such as age-related cognitive impairment, mild cognitive impairment (MCI), amnesic MCI (aMCI), age-related memory impairment (AAMI), age-related cognitive decline (ARCD), dementia, Alzheimer's disease (AD), prodromal AD, post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder, amyotrophic lateral sclerosis (ALS), cognitive impairment associated with cancer treatment, intellectual disability, Parkinson's disease (PD), autism, obsessive-compulsive behavior, and substance addiction). The combined effect of the treatment of the aforementioned cognitive impairment was greater than the effect that would have been expected to be merely additive. Furthermore, this effect should be observed in the treatment of cognitive impairment associated with brain cancer, brain cancer, and Parkinson's disease psychiatry in subjects requiring treatment. Also, SV2A inhibitors (e.g., levetiracetam, brivalacetam, or celetracetam), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs or isomers, and GABA A α5 receptor agonists (e.g., compounds of formula I, II, or IV; compounds 1-740 and 1-114 mentioned above; or form A, form B, form C, form E, or form F of compound 1), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers, have different mechanisms of action, and their synergistic effects are remarkable.

[0100] SV2A inhibitors (e.g., levetiracetam, brivalacetam, or celetracetam), or pharmaceutically acceptable salts thereof, their hydrates, their solvates, their polymorphs or isomers, and GABA A This synergistic combination of α5 receptor agonists (e.g., compounds of formula I, II, or IV; compounds 1-740, 1-114 mentioned above; or form A of compound 1, form B of compound 1, form C of compound 1, form E of compound 1, or form F of compound 1), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers, is also effective with SV2A inhibitors (e.g., levetiracetam, brivalacetam, or celetracetam), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers, and GABA A α5 receptor agonists (e.g., compounds of formula I, formula II, or formula IV; compounds 1-740, compounds 1-114; or form A, form B, form C, form E, or form F of compound 1), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers, can be administered in lower therapeutic doses than those normally used when used alone to treat disorders with cognitive impairment. Such lower doses allow for the administration of SV2A inhibitors (e.g., levetiracetam, brivalacetam, or celetracetam), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers, and GABA ANegative side effects or toxicity that may occur in connection with the administration of α5 receptor agonists (e.g., compounds of formula I, II, or IV; compounds 1-740, 1-114 mentioned above; or form A, form B, form C, form E, or form F of compound 1), or their pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or isomers can be mitigated or prevented. Furthermore, despite lower dose administration, the synergistic effect of the combination may not only not result in loss of efficacy but may even improve it, allowing for longer-lasting therapeutic effects. The enhancement of therapeutic efficacy through the use of combinations can improve treatment outcomes without the need to increase the dose or frequency of administration. In some settings, increased dosage may be beneficial for treatment but may sometimes exacerbate negative side effects or lead to toxicity, thus necessitating new treatment regimens, particularly those tailored to chronic conditions or administered over long periods. Moreover, negative side effects and increased dosage may reduce patient adherence to treatment. SV2A inhibitors (e.g., levetiracetam, brivalacetam, or celetracetam), or pharmaceutically acceptable salts thereof, their hydrates, their solvates, their polymorphs or isomers, and GABA Aα5 receptor agonists (e.g., compounds of formula I, II, or IV; compounds 1-740, 1-114 mentioned above; or form A, form B, form C, form E, or form F of compound 1), or pharmaceutically acceptable salts thereof, their hydrates, their solvates, or combinations of their polymorphs or isomers, are useful for the long-term treatment of cognitive impairments associated with CNS disorders (such as age-related cognitive impairment, mild cognitive impairment (MCI), amnesic MCI (aMCI), age-related memory impairment (AAMI), age-related cognitive decline (ARCD), dementia, Alzheimer's disease (AD), prodromal AD, post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder, amyotrophic lateral sclerosis (ALS), cognitive impairment associated with cancer treatment, intellectual disability, Parkinson's disease (PD), autism, obsessive-compulsive behavior, and substance addiction), and the observed synergistic effects are therefore advantageous. Furthermore, the combination is useful for treating cognitive impairments associated with brain cancer, brain cancer, and Parkinson's disease psychiatric disorders in patients requiring treatment.

[0102] The chemical terms used herein are used in accordance with the conventional usage in the art, as illustrated in "The McGraw-Hill Dictionary of Chemical Terms," ​​Parker S., Ed., McGraw-Hill, San Francisco, CA (1985).

[0103] All publications, patents, and published patent applications referenced in this application are incorporated by specific reference herein. In case of any conflict, this specification, including its specific definitions, shall prevail.

[0104] Throughout this specification, variations of the word “comprise,” “comprises,” or “comprising” are understood to mean the inclusion of a specified integer (or component) or group of integers (or components), but not the exclusion of any other integer (or component) or group of integers (or components).

[0105] The singular forms "a," "an," and "the" include the plural unless the context specifically indicates otherwise.

[0106] The term "including" is used to mean "including but not limited to these." "Including" and "including but not limited to these" are used interchangeably.

[0107] The terms “patient,” “subject,” or “individual” are used interchangeably and may refer to either a human or a non-human animal. Patients, subjects, or individuals include mammals (humans, primates, domestic animals (including cattle, pigs, etc.), companion animals (e.g., dogs, cats, etc.) and rodents (e.g., mice and rats). In some embodiments, the patient, subject, or individual is human.

[0108] "Cognitive function" or "cognitive state" can refer to any higher-order intelligent brain processes or states related to learning and / or memory, including, but not limited to, attention, information acquisition, information processing, working memory, short-term memory, long-term memory, anterograde memory, retrograde memory, memory retrieval, discriminative learning, decision-making, inhibitory response control, attentional set shift, delayed reinforcement learning, reverse learning, time integration of spontaneous behavior, as well as display of interest in the surrounding environment and self-care, processing speed, reasoning and problem-solving, and social cognition.

[0109] "Facilitation" of cognitive function can refer to the effect of influencing impaired cognitive function to closely resemble that of a normal individual. Cognitive function can be facilitated to any detectable degree, but in humans, it can be facilitated sufficiently so that an individual with impaired cognitive function can perform daily activities of normal life at a level of proficiency as close as possible to that of a normal individual or a normal individual of the same age.

[0110] In some embodiments, “facilitation” of cognitive function in an affected subject due to age-related cognition means that the impaired cognitive function is affected to such an extent that it closely resembles the function of a normal subject of the same age or a young adult subject. The subject’s cognitive function may be facilitated to any detectable degree, but in humans, it may be facilitated enough for the impaired subject to be able to perform the daily activities of normal life at a level of proficiency as close as possible to that of a normal subject, a young adult subject, or a normal subject of the same age.

[0111] "Protection" of cognitive function can refer to influencing normal or impaired cognitive function in such a way that it does not decline, does not fall below the level observed in the subject at the time of initial presentation or diagnosis, or delays such decline.

[0112] "Improvement" of cognitive function may include promoting and / or protecting cognitive function in the subject.

[0113] "Cognitive impairment" can refer to cognitive function in an individual that is not as robust as the cognitive function expected in a normal individual. In some cases, cognitive function is reduced by approximately 5%, 10%, 30%, or more compared to the cognitive function expected in a normal individual. In some cases, "cognitive impairment" in an individual affected by age-related cognitive impairment can refer to cognitive function in an individual that is not as robust as the cognitive function expected in an individual of the same age or in a young adult individual (i.e., an individual with an average score for a given age on a cognitive test).

[0114] In patients requiring treatment, “treating brain cancer-related cognitive impairment” or “treating brain cancer” can mean taking steps to achieve beneficial or desired outcomes, including clinical outcomes. Beneficial or desired clinical outcomes may include, but are not limited to, improvement of cognitive function in patients with brain cancer; delay or slowing of the progression of brain cancer or cognitive impairment in patients with brain cancer; slowing of the rate of cognitive decline in patients with brain cancer; prevention or slowing of the progression of brain cancer or brain cancer-related cognitive impairment; or reduction, improvement, or slowing of the progression of one or more symptoms associated with brain cancer or brain cancer-related cognitive impairment.

[0115] In patients requiring treatment, “treating Parkinson’s disease psychiatry” can mean taking steps to achieve beneficial or desired outcomes, including clinical outcomes. Beneficial or desired clinical outcomes may include, but are not limited to, improvement of Parkinson’s disease psychiatry; delay or slowing of its progression; prevention or slowing of its progression; or reduction, improvement, or slowing of the progression of one or more symptoms associated with Parkinson’s disease psychiatry.

[0116] "Treating cognitive impairment" can refer to taking steps to improve the cognitive function of an individual with cognitive impairment so that their performance on one or more cognitive tests improves to any detectable level or prevents further decline. The cognitive function of the individual may closely resemble that of an unimpaired, normal individual after treatment. Treatment of cognitive impairment in humans can improve cognitive function to any detectable level, but it can be sufficient to enable the impaired individual to perform daily activities of normal life at the same level of proficiency as a normal individual. In some cases, "treating cognitive impairment" can refer to taking steps to improve the cognitive function of an individual with cognitive impairment so that their performance on one or more cognitive tests improves to any detectable level or prevents further decline. The cognitive function of the individual may closely resemble that of a normal individual after treatment. In some cases, "treating cognitive impairment" in subjects affected by age-related cognitive impairment may refer to taking steps to improve the subject's cognitive function so that, after treatment, the subject's cognitive function closely resembles that of a normal subject of the same age or a young adult subject. In some cases, "treating cognitive impairment" in subjects may refer to taking steps to delay or slow the progression of cognitive impairment in subjects with cognitive impairment. In some cases, "treating cognitive impairment" in subjects may refer to taking steps to slow the rate of decline in cognitive function in subjects with cognitive impairment.Beneficial or desired clinical outcomes include, but are not limited to, improved cognitive function; delayed or slowed progression of cognitive impairment; slowed rate of cognitive decline; prevention of disease or impairment or slowed progression thereof; or reduction, improvement, or slowed progression of one or more symptoms associated with cognitive impairment related to CNS disorders (such as age-related cognitive impairment, mild cognitive impairment (MCI), amnesic MCI, age-related memory impairment (AAMI), age-related cognitive decline (ARCD), dementia, Alzheimer's disease (AD), prodromal AD, PTSD, schizophrenia or bipolar disorder (especially mania), amyotrophic lateral sclerosis (ALS), cognitive impairment associated with cancer treatment, intellectual disability, Parkinson's disease (PD), autism, obsessive-compulsive behavior, or substance addiction).

[0138] SV2A inhibitors as described herein, or pharmaceutically acceptable salts thereof, polymorphs or isomers thereof, or GABA as described herein A α5 receptor agonists, or pharmaceutically acceptable salts thereof, their polymorphs or isomers, may also be in the form of solvates, which are included within the scope of this disclosure. Such solvates include, for example, hydrates, alkoxides, etc. See, for example, WO01 / 062726.

[0139] As used herein, the term “hydrate” refers to a combination of water and a compound, in which case the water retains its molecular state as water and is either absorbed, adsorbed, or contained within the crystal lattice of the compound.

[0140] As used herein, the term “polymorph” refers to different crystalline forms and molecular forms of other solid states (including pseudopolymorphs) of the same compound, such as hydrates (e.g., bound water present in the crystalline structure) and solvates (e.g., bound solvents other than water). Different crystalline polymorphs have different crystalline structures due to different molecular packing within their lattices. This results in different crystal symmetries and / or unit cell parameters, which directly affect their physical properties, such as the X-ray diffraction characteristics of the crystal or powder. For example, different polymorphs generally diffract at different sets of angles, resulting in different values ​​for their intensities. Thus, powder X-ray diffraction can be used to identify solid states containing different polymorphs, or more than one polymorph, in a reproducible and reliable manner. Crystallographic polymorphisms are of interest to the pharmaceutical industry and, in particular, to those involved in the development of suitable dosage forms. If the polymorphisms are not kept constant during clinical or stability studies, the very dosage form used or studied may not be comparable from lot to lot. When a compound is used in clinical studies or in products, the presence of impurities may lead to undesirable toxicological effects; therefore, it is desirable to have a process for producing the compound in high purity with selected polymorphic forms. Certain polymorphic forms may exhibit improved thermodynamic stability or may be easier to produce in large quantities with high purity, and are therefore more suitable for inclusion in pharmaceutical formulations. Certain polymorphic forms may exhibit other beneficial physical properties, such as no tendency to absorb moisture, improved solubility, and improved dissolution rates due to different lattice energies.

[0141] This application intends all isomers of the compounds disclosed herein. As used herein, “isomer” includes optical isomers (stereoisomers, e.g., enantiomers and diastereoisomers), Z (zusammen) or E (entgegen) isomers, and tautomers. Many of the compounds useful in the methods, uses, combinations, pharmaceutical compositions, combinations for use, or pharmaceutical compositions for use of this disclosure have at least one stereogenic center in their structure. This stereogenic center may exist in an R or S configuration, and the notation R and S is used according to the rules described in Pure Appl. Chem. (1976), 45, 11-30. The present invention also relates to all stereoisomers, such as enantiomers and diastereoisomers of the compounds herein, or mixtures thereof (including all possible mixtures of stereoisomers). See, for example, WO01 / 062726. Furthermore, certain compounds containing an alkenyl group may exist as Z (zusammen) or E (entgegen) isomers. In each case, the disclosure includes mixtures of both and distinct individual isomers. Multiple substituents on the piperidinyl or azepanyl ring may also be in a cis or trans relationship with respect to the plane of the piperidinyl or azepanyl ring. Some of the compounds may also exist as tautomers. Such forms, though not expressly shown, are intended to be included within the scope of the disclosure. When referring to a compound(s) or compound(s) in relation to the methods, uses, combinations, pharmaceutical compositions, combinations for use, or pharmaceutical compositions for use of the disclosure, it is intended that the compound be encompassed in each of its possible isomers and mixtures thereof unless a specific isomer is specifically mentioned. See, for example, WO01 / 062726.

[0142] The term “aliphatic,” as used herein, refers to linear or branched alkyl, alkenyl, or alkynyl groups.

[0149] The term "heteroaralkyl" can refer to an alkyl group in which a heteroaryl group is substituted with an alkyl hydrogen atom. For example, the alkyl group can be any linear hydrocarbon and may contain 1 to 12 carbon atoms (e.g., methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, and dodecyl), and the alkyl group is not limited to the following: 2-furanyl, 3-furanyl, N-imidazolyl, 2-imidazolyl, 4-imidazolyl, 5-imidazolyl, benzimidazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-oxazolyl, 4-oxazolyl, 5-oxazolyl, N-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidinyl, 4-pyrimidinyl, 5-pyrimidinyl, pyridazinyl (e.g., 3-pyrimidinyl), 2-thiazolyl, 4-thiazolyl, 5-thiazolyl tetrazolyl (e.g., 5-tetrazolyl), triazolyl (e.g., 2-triazolyl and 5-triazolyl), 2-thienyl, 3-thienyl, benzofuryl, benzothiophenyl, indolyl (e.g., 2-indolyl), pyrazolyl (e.g., 2-pyrazolyl), isothiazolyl, 1,2,3-oxadiazolyl, 1,2,5-oxadiazolyl, 1,2,4-oxadiazolyl, 1,2,3 It may be substituted with any heteroaryl group, including triazolyl, 1,2,3-thiadiazolyl, 1,3,4-thiadiazolyl, 1,2,5-thiadiazolyl, prinyl, pyrazinyl, 1,3,5-triazinyl, quinolinyl (e.g., 2-quinolinyl, 3-quinolinyl, 4-quinolinyl) and isoquinolinyl (e.g., 1-isoquinolinyl, 3-isoquinolinyl, or 4-isoquinolinyl).

[0150] If a substitution is described without indicating an atom, and such a substitution is bonded to a substituent via this atom, the substituent may be bonded via any suitable atom in such a substitution. For example, in the case of a substituted 5- to 10-membered heteroaryl, the substituent on the heteroaryl may be bonded to any of the ring-forming atoms of the substitutionable heteroaryl ring (i.e., atoms bonded to one or more hydrogen atoms).

[0151] Where a bond to a substituent is described as intersecting a bond linking two atoms in a ring, such substituent may be bonded to any of the substituted ring-forming atoms in that ring (i.e., an atom bonded to one or more hydrogen atoms), unless otherwise specified or particularly implied in the context. For example, if the R group is defined as pyridine, and the pyridine is as follows: [ka] As illustrated, the pyridine ring may be bonded to the benzodiazepine derivative via any one of the ring carbon atoms within the pyridine ring. Alternatively, the R group may be defined as a pyrazole, and the pyrazole may be: [ka] When illustrated as shown, this pyrazole ring is any one of the ring carbon atoms within the pyrazole ring or sp 3 The N atom may be bonded to a benzodiazepine derivative.

[0152] The designation of carbon atoms, as used herein, may have the given integer and any intervening integer. For example, the number of carbon atoms in (C1-C4) alkyl groups is 1, 2, 3, or 4. It should be understood that these designations refer to the total number of atoms in the appropriate group. For example, in (C3-C10) heterocyclils, the total number of carbon atoms and heteroatoms is 3 (as in aziridine), 4, 5, 6 (as in morpholine), 7, 8, 9, or 10.

[0167] "Antipsychotic drugs," "antipsychotic agents," "antipsychotic medications," or "antipsychotic compounds" refer to (1) typical or atypical antipsychotic drugs; (2) dopamine agonists, glutamate agonists, NMDA receptor positive allosteric modulators, glycine reuptake inhibitors, glutamate reuptake inhibitors, metabotropic glutamate receptor (mGluR) agonists or positive allosteric modulators (PAMs) (e.g., mGluR2 / 3 agonists or PAMs), glutamate receptor gluR5 positive (3) This can refer to drugs selected from ibuallosteric modulators (PAMs), M1 muscarinic acetylcholine receptor (mAChR) positive allosteric modulators (PAMs), histamine H3 receptor antagonists, AMPA / kainate receptor antagonists, ampakine (CX-516), glutathione prodrugs, noradrenergic agonists, serotonin receptor modulators, cholinergic agonists, cannabinoid CB1 antagonists, neurokinin 3 antagonists, neurotensin agonists, MAO B inhibitors, PDE10 inhibitors, nNOS inhibitors, neurosteroids and neurotrophic factors, alpha-7 agonists or positive allosteric modulators (PAMs), serotonin 2C agonists, and / or (3) drugs useful for treating one or more signs or symptoms of schizophrenia or bipolar disorder (especially mania).

[0168] As used herein, “typical antipsychotics” can refer to conventional antipsychotics that produce antipsychotic effects as well as motor-related adverse effects associated with disorders of the dopamine system in the substantia nigra and striatum. These extrapyramidal side effects (EPS) include parkinsonism, zodiac immobility, tardive dyskinesia, and dystonia. See Baldessarini and Tarazi in Goodman & Gilman's The Pharmacological Basis of Therapeutics, 10th Edition, 2001, pp. 485–520.

[0169] As used herein, “atypical antipsychotics” refers to antipsychotics that produce antipsychotic effects with little or no EPS, and these include, but are not limited to, aripiprazole, asenapine, clozapine, iloperidone, olanzapine, lurasidone, paliperidone, quetiapine, risperidone, and ziprasidone. “Atypical” antipsychotics differ from conventional antipsychotics in their pharmacological profile. Conventional antipsychotics are primarily characterized by blockade of D2 dopamine receptors, while atypical antipsychotics are characterized by blockade of 5HT a and 5HT c Atypical antipsychotics exhibit antagonistic activity and varying degrees of receptor affinity to multiple receptors, including serotonin receptors. Often referred to as serotonin / dopamine antagonists, their higher affinity for 5HT2 receptors than for D2 receptors reflects the intriguing hypothesis that this underlies the action of “atypical” or “second-generation” antipsychotics. However, atypical antipsychotics often cause side effects, including, but are not limited to, weight gain, diabetes (e.g., type II diabetes), hyperlipidemia, QTc interval prolongation, myocarditis, sexual side effects, extrapyramidal side effects, and cataracts. Therefore, atypical antipsychotics are not a homogeneous class, considering the differences in both clinical symptom relief and the potential for inducing side effects such as those listed above. Furthermore, the common side effects of atypical antipsychotics described above often limit the dosage of antipsychotics that can be used for these medications.

[0170] Memantine is 3,5-dimethyladamantan-1-amine or 3,5-dimethyltricyclo[3.3.1.1 3,7It is chemically known as decane-1-amine and is a moderately affinity, non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist. Trademark names for memantine include Axura® and Akatinol® (Merz), Namenda® (Forest Laboratories), Ebixa® and Abixa® (Lundbeck), and Memox® (Unipharm). Memantine is approved in the United States for the treatment of moderate to severe Alzheimer's disease (AD) at a maximum dose of 28 mg / day.

Memantine, as used herein, also includes compositions comprising memantine or its derivatives or analogs, or pharmaceutically acceptable salts, hydrates, solvates, polymorphs, or prodrugs, in which case the composition optionally further comprises at least one further therapeutic agent (such as a therapeutic agent useful for treating CNS disorders or associated cognitive impairments). In some embodiments, a memantine composition suitable for use in this disclosure comprises memantine and a second therapeutic agent, donepezil (trade name Aricept).

[0171] As used herein, “acetylcholinesterase inhibitor” or “AChE-I” refers to a drug that inhibits the ability of the cholinesterase enzyme to break down the neurotransmitter acetylcholine, thereby increasing the concentration and duration of acetylcholine, primarily at brain synapses or neuromuscular junctions. Suitable AChE-Is for use in this application may include, for example, the subcategories of (i) reversible non-competitive inhibitors or reversible competitive inhibitors, (ii) irreversible inhibitors, and (iii) quasi-irreversible inhibitors. Donepezil is an example of an AChE-I.
