[0002] 2. Background of the Invention Mitochondrial dysfunction can affect cellular function in several ways. First, mitochondria are the main source of ATP as cellular power plants. Mitochondrial dysfunction leads to a lack of cellular energy and compromises the maintenance of cellular vitality. Second, mitochondria possess the electron transport chain involved in oxidative phosphorylation. This process generates reactive oxygen species (ROS) that can perform some signaling functions under basal conditions, but defective mitochondria are inefficient in the electron transfer process, leading to elevated ROS production, which can cause damage to various macromolecules (proteins, nucleic acids, lipids, etc.). This oxidative damage is widely associated with diseases, especially age-related diseases. Third, mitochondria are important organelles in maintaining cellular calcium homeostasis. Mitochondria import calcium released from intracellular stores, especially the ER, or calcium generated by excitation. Mitochondrial dysfunction can alter cellular calcium homeostasis and lead to conditions such as ER stress, which is associated with several disease states. In addition, mitochondrial calcium is essential for the activity of certain enzymes in the TCA cycle and the electron transport chain. Thus, alterations in mitochondrial calcium homeostasis can result in mitochondrial energy insufficiency. Finally, mitochondria act as gatekeepers of cell life and death, controlling both apoptotic and necrotic cell death. Thus, at the cell's end, impairments in these pathways can induce premature cell death, leading to degenerative diseases. Conversely, lack of proper cell death can lead to inappropriate tissue growth and cancer development, which are often characterized by alterations in mitochondrial metabolism.
[0003] A number of major human diseases, many of which represent urgent unmet medical needs, are associated with mitochondrial dysfunction, ranging from cancer and neurodegenerative diseases (e.g., Alzheimer's disease, Parkinson's disease, and ALS, to brain injuries such as stroke, seizures, neuropathic pain, traumatic brain injury, spinal cord injury, aneurysm, and subarachnoid hemorrhage) to certain non-neurological disorders (e.g., sepsis, acute kidney injury, cardiorenal syndrome, cardiac ischemia-reperfusion injury, pulmonary arterial hypertension, chronic obstructive pulmonary disease, and vasoconstriction).

Where "reduce," "inhibit," or "prevent" are used herein, it will be understood that the use of the other two words is also expressly disclosed, unless specifically indicated otherwise.
[0024] The term "diagnosed" as used herein means that upon examination by a person of ordinary skill in the art, e.g., a physician, the individual is determined to have a condition that can be diagnosed or treated with the compounds, compositions, or methods disclosed herein.
[0025] As used herein, the phrase "identified as needing treatment of disorder" refers to the selection of a subject based on the need for treatment of disorder.For example, a subject can be identified as needing treatment of disorder (e.g., Alzheimer's disease-related disorder) based on early diagnosis by a person skilled in the art, and then be treated for said disorder.In one aspect, it is assumed that the person who made the diagnosis may perform the identification.In a further aspect, it is assumed that the person who made the administration can perform the administration subsequently.
[0026] The terms "administering" and "administration" as used herein refer to any method of providing a pharmaceutical formulation to a subject. These methods are well known to those skilled in the art and include, but are not limited to, oral administration, transdermal administration, inhalation administration, nasal administration, topical administration, intravaginal administration, ophthalmic administration, intraaural administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injection administration, such as intravenous administration, intraarterial administration, intramuscular administration, and subcutaneous administration. Administration can be continuous or intermittent. In various aspects, the formulation can be administered therapeutically, i.e., administered to treat an existing disease or condition. In further various aspects, the formulation can be administered prophylactically, i.e., administered for the prevention of a disease or condition.
[0027] As used herein, the term "contacting" refers to the association of a disclosed compound with a cell, target receptor, or other biological entity such that the compound can affect the activity of the target (e.g., receptor, transcription factor, cell, etc.) either directly, i.e., by interacting with the target itself, or indirectly, i.e., by interacting with another molecule, cofactor, factor, or protein on which the activity of the target depends.
[0028] The terms "effective amount" and "amount effective" as used herein refer to an amount sufficient to obtain a desired result or to have an effect on an undesired condition. For example, a "therapeutically effective amount" refers to an amount sufficient to obtain a desired therapeutic effect or to have an effect on an undesired symptom, but generally insufficient to cause adverse side effects. The specific therapeutically effective amount level for any particular patient will depend on a variety of factors, including the disorder being treated and the severity of the disorder; the particular composition being used; the age, weight, general health, sex, and diet of the patient; the time of administration; the route of administration; the rate of excretion of the particular compound being used; the duration of treatment; drugs used in combination or concomitantly with the particular compound being used, and similar factors well known in the medical field. For example, it is well within the skill of the art to begin administering a compound at a level lower than that required to obtain the desired therapeutic effect, and gradually increase the dosage until the desired effect is obtained. If desired, the effective daily amount may be divided into multiple doses for administration purposes. Thus, a single dose of the composition may contain an amount that constitutes a daily dose, or a fraction thereof. In the event of any contraindications, the dosage may be adjusted by the individual physician. Dosage can vary and can be administered in one or more doses daily for one or several days. Guidance regarding appropriate dosages for a given class of pharmaceutical agent can be found in the literature. In various further aspects, the formulation can be administered in a "prophylactically effective amount", i.e., an amount effective for the prevention of a disease or condition.

[0030] The term "salt" used herein refers to the acid salt or base salt of the compound of the present invention.The examples of pharmaceutically acceptable salts include the salts of mineral acids (such as hydrochloric acid, hydrobromic acid, phosphoric acid, etc.), the salts of organic acids (such as acetic acid, propionic acid, glutamic acid, citric acid, etc.) and the salts of quaternary ammonium (such as methyl iodide, ethyl iodide, etc.).It is understood that pharmaceutically acceptable salts are non-toxic.
[0031] Pharmaceutically acceptable salts of acidic compounds of the invention include salts formed with bases, i.e., cationic salts, such as alkali metal and alkaline earth metal salts (e.g., sodium, lithium, potassium, calcium, and magnesium salts), and ammonium salts (e.g., ammonium, trimethylammonium, diethylammonium, and tris-(hydroxymethyl)-methyl-ammonium salts).
[0032] Similarly, acid addition salts, such as salts of mineral acids, organic carboxylic acids, and organic sulfonic acids, e.g., hydrochloric acid, methanesulfonic acid, maleic acid, are also possible, provided that a basic group, such as pyridyl, forms part of the structure.
[0033] The neutral forms of the compounds can be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms with respect to certain physical properties, such as solubility in polar solvents, but otherwise the salts are identical to the parent forms of the compounds of this invention.
[0034] As used herein, the term "optionally" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes cases where the event or circumstance occurs and cases where it does not occur.

[0073] Also provided are methods and compositions for reducing cancer cell proliferation, for example, in individuals with cancer, for example, to treat the cancer. Cancer refers to a group of diseases involving uncontrolled cell proliferation. In cancer, cells grow or divide uncontrollably, forming malignant tumors and invading nearby parts of the body. Cancer can also metastasize or spread to more distant parts of the body through the lymphatic system or bloodstream. Treatment can be preventive in terms of complete or partial prevention of cancer or its symptoms, and / or therapeutic in terms of partial or complete cure of cancer and / or the adverse effects that may result from the cancer.
[0074] Treating cancer may include (a) preventing the development of cancer in a subject who may be susceptible to cancer but has not yet been diagnosed with cancer; (b) inhibiting cancer, i.e., halting the development of cancer; or (c) alleviating cancer, i.e., causing regression of cancer. Therapeutic agents can be administered before, during, or after the onset of cancer. Treating ongoing cancer is of particular interest if the treatment stabilizes or reduces undesirable clinical symptoms in the patient. This treatment is desirably performed before complete loss of function of the affected tissue. The therapeutic agent is desirably administered during, and in some cases after, the symptomatic stage of cancer. The terms "individual," "subject," "host," and "patient" are used interchangeably herein and refer to any mammalian subject, particularly a human, for whom diagnosis, treatment, or therapy is desired. In some cases, the methods and compositions reduce, e.g., inhibit, the growth of cancer. In some cases, the methods and compositions reduce, e.g., inhibit, the metastasis of cancer.
[0075] In some embodiments, the cancer is a Notch-associated cancer, i.e., associated with or at least partially caused by active Notch signaling. By "Notch" is meant an evolutionarily conserved single-pass transmembrane receptor that influences numerous cell fate decisions through short-range cell-cell interactions (Artavanis-Tsakonas and Muskavitch 2010). Notch proteins (cLIN-12 and cGLP-1 in C. elegans, Notch in Drosophila, Notch1-4 in mammals) consist of a ligand-binding extracellular domain (NECD) with 29-36 epidermal growth factor (EGF) repeats, a transmembrane domain, and a transcriptionally active intracellular domain (NICD). By "active Notch signaling" is meant that the Notch protein is active in the cancer cells, e.g., the Notch protein is activated Notch or constitutively active Notch, e.g., the Notch protein is mutated such that the Notch protein or one of its domains is always active. Examples of Notch-associated cancers include hematological malignancies, such as acute lymphoblastic leukemia (T-ALL); breast tumors, such as breast cancer; brain tumors, such as glioblastoma multiforme (GBM); lung cancer; and intestinal cancer (Artavanis-Tsakonas and Muskavitch 2010). Cancers can be easily identified as Notch-associated cancers by detecting Notch mutations in cancerous cells, such as in tumor biopsy tissue or cell smears, that result in constitutively active Notch. Several mutations that result in constitutively active Notch signaling have been identified, which can be detected, for example, by chromosomal dispersion or PCR, as known in the art. Alternatively, cancers can be identified as Notch-associated cancers by detecting upregulation of the activity of downstream effectors of Notch signaling, such as upregulation of the activity of non-canonical Notch signaling proteins, such as increased PINK1 expression, increased mTORC2 signaling (increased Akt phosphorylation), and increased assembly of respiratory chain complexes, compared to non-cancerous cells.
[0076] Notch proteins regulate cellular activities through canonical and non-canonical pathways. In canonical Notch pathway signaling, Notch ligands (transmembrane proteins containing three motifs, DSL (Delta, Serrate, LAG-2), DOS (Delta and OSM-11-like), and EGF repeats) bind to the EGF repeats of the Notch extracellular domain in neighboring cells. Ligand-Notch interaction leads to cleavage of the Notch extracellular domain by members of the α-secretase / metalloprotease family (ADAM10 / Kuzmanian, ADAM17 / TACE), followed by cytoplasmic cleavage of the Notch intracellular domain by γ-secretase (a multisubunit protease complex composed of presenilin (PS), nicastrin (NCT), Aph-1, Pen-2, etc.). The released intracellular domain translocates to the nucleus, where it interacts with the DNA-binding transcription factor CSL (CBF1 / RBPjk in vertebrates, Suppressor of Hairless in Drosophila, Lag-1 in C. elegans) through its RAM domain and transcriptionally activates Notch target genes by acting as a coactivator for other cofactors such as CSL, Mastermind-like protein (MAML1 in vertebrates, Mastermind in Drosophila, Lag-3 in C. elegans), and CBP / p300 (Kopan and Ilagan 2009). In the absence of the released intracellular domain Notch, CSL functions as a sequence-specific repressor. Thus, genes that mediate canonical Notch signaling (i.e., "canonical Notch signaling genes") would include genes encoding polypeptides of the γ-secretase complex, CSL ("CBF1 / RBPjk" in vertebrates, "Suppressor of Hairless" in Drosophila, "Lag-1" in C. elegans), Mastermind-like proteins ("MAML1" in vertebrates, "Mastermind" in Drosophila, "Lag-3" in C. elegans), and the CBP / p300 gene.
[0077] Notch can also signal through non-canonical pathways. Non-canonical Notch signaling is CSL-independent and can be ligand-dependent or ligand-independent (Kopan and Ilagan 2009). Although several genes are affected by non-canonical Notch function, in most cases, the mediators of non-canonical Notch signaling are unknown. The most well-studied and conserved effect of non-canonical Notch function is the regulation of Wnt / β-catenin signaling. In this non-canonical Notch signaling pathway, Notch binds to and determines the levels of active β-catenin, an essential Wnt signaling component (Takebe et al. 2011). Thus, active β-catenin activity can serve as a useful readout of non-canonical Notch signaling. Other investigated non-canonical Notch signaling pathways include signaling through NF-κB, signaling through the JNK pathway, and signaling through HES1 and MCK (Andersen et al. 2012).
[0078] Recently, mTORC2, Akt, and proteins that promote mitochondrial biogenesis or function, such as PINK1, mitochondrial respiratory chain complex proteins, mitochondrial fission proteins, and mitochondrial biogenesis proteins, have been discovered to mediate non-canonical Notch signaling (Lee et al. 2013). For example, polypeptides of mitochondrial respiratory chain complex I (e.g., 75 kDa subunit ND-75), mitochondrial fission protein Dynamin-1-like protein (Drp1), and mitochondrial biogenesis protein peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1alpha). Importantly, many of these genes in the non-canonical Notch signaling pathway code for proteins that control mitochondrial function (Lee et al. 2013). The compounds of the present disclosure can be used to target Notch-promoted cancer cell proliferation, such as the proliferation of T-ALL (Molt-4, Jurkat cell lines) and glioblastoma (T98G, U118MG cell lines).
[0079] Notch signaling, as a key regulator of neuronal development and function, is deeply involved in many aspects of brain development, function, and maintenance. Dysregulation of Notch signaling is involved in the pathogenesis of brain tumors, stroke, neurodegeneration, neuropathic pain, traumatic brain injury, depression, and neuropsychiatric disorders (Mathieu et al., 2013; Zhang et al., 2018; Alfred and Vaccari, 2018). The fact that the outcome of Notch signaling is highly context-dependent suggests that non-canonical Notch function may be the rule rather than the exception. The fact that efficient inhibition of canonical Notch signaling has proven too toxic for clinical use, mainly due to unwanted on-target effects (Andersson and Lendahl, 2014), suggests that extending methods for modulating the Notch signaling pathway beyond the canonical pathway will broaden the available range of therapeutic options. Compounds of the present disclosure can be used to inhibit aberrant Notch activation through non-canonical pathways and treat a wide range of brain disorders and conditions.

[0082] Dosage may vary depending on the patient's requirements, the severity of the disease or condition being treated, and the specific formulation being administered. The dosage administered to a patient should be sufficient to obtain a beneficial therapeutic response in the patient. The size of the dosage is also determined by the existence, nature, and extent of any adverse side effects that accompany the administration of the drug in a particular patient. Determining the dosage that is appropriate for a particular situation is within the skill of a typical medical practitioner. The total dosage can be divided and administered in portions over a suitable time period to treat the disease or condition.
[0083] The administration of the compounds and compositions of the present disclosure can be carried out over a period of time that varies depending on the nature of the particular disorder, its severity, and the general condition of the patient. Administration can be carried out twice a day, including, for example, every hour, every 2 hours, every 3 hours, every 4 hours, every 6 hours, every 8 hours, or every 12 hours, or at intermediate intervals therebetween. Administration can be carried out once a day, once every 36 hours or every 48 hours, or once every month or several months. After treatment, the patient can be monitored for changes in his or her condition and relief of symptoms of the disorder. If the patient does not respond significantly to a particular dosage level, the dosage of the particular compound can be increased, and if relief of symptoms is observed or if unacceptable side effects are seen at a particular dosage, the dosage can be reduced. The administration regimen can consist of two or more different interval sets. For example, the first part of the administration regimen can be carried out to the subject multiple times a day, once a day, once every two days, or once every three days. The dosing regimen may begin by administering the drug to the subject once every 2 days, once every 3 days, once a week, once every 2 weeks, or once a month. The first portion of the dosing regimen may be administered for up to 30 days, for example, 7 days, 14 days, 21 days, or 30 days. A subsequent second portion of the dosing regimen with a different interval of administration may follow, administered once a week, once every 14 days, or once a month, lasting from 4 weeks up to 2 years or more, for example, 4 weeks, 6 weeks, 8 weeks, 12 weeks, 16 weeks, 26 weeks, 32 weeks, 40 weeks, 52 weeks, 63 weeks, 68 weeks, 78 weeks, or 104 weeks. Alternatively, if symptoms go into remission or gradually improve, the dosage may be maintained or kept below the maximum amount. If the condition or symptoms worsen, the first dosing regimen may be resumed until improvement is observed, and the second dosing regimen may be administered again. This cycle may be repeated multiple times as necessary. EXAMPLES
