Description

BACKGROUND

Tumor necrosis factor (“TNF”) receptor associated protein 1 (“TRAP1”) has been reported to be a chaperone responsible for maintaining the mitochondrial quality and energy metabolism found in the mitochondrial matrix (Altieri et al., Biochim Biophys Acta 2012, 1823: 767-73; Rasola et al., Trends Cell Biol., 2014, 24, 455-463). TRAP1 may have a regulatory role in stress sensing in mitochondria allowing cellular adaption to the environment (Fitzgerald et al., Brain 2017: 140; 2444-2459). It has been reported that TRAP1 may be associated with a range of diseases, such as Parkinson's disease (Pridgeon et al., PLoS Biol., 2007, 5, e172; van Ham et al., PLoS Genetics, 2008, Volume 4, Issue 3, e1000027; Costa et al., Cell Death and Disease (2013) 4, e467; Fitzgerald et al., Brain, 2017, 140, 2444-2459; Rai et al., Frontiers in Aging Neuroscience, 2018, Volume 10, Article 221); congenital abnormalities of the kidney and urinary tract (“CAKUT”) and VACTERL association (Saisawat et al., Kidney International (2014) 85, 1310-1317); pain, fatigue and gastrointestinal dysmotility (Boles et al., Mitochondrion 23 (2015) 64-70); severe autoinflammatory disease (Standing et al., Life Science Alliance 3 (2019) e201900376 [p1-12]). There is a need for developing improved therapy of diseases associated with TRAP1.

SUMMARY OF THE DISCLOSURE

In one aspect, the present disclosure provides a compound of Formula (I):

or a pharmaceutically acceptable salt, solvate, hydrate, polymorph, co-crystal, tautomer, stereoisomer, isotopically labeled compound, or prodrug thereof. The provided compounds may be tumor necrosis factor (“TNF”) receptor associated protein 1 (“TRAP1”) modulators (e.g., TRAP1 activators). In certain embodiments, the provided compounds increase the activity (e.g., ATPase activity) of TRAP1. In certain embodiments, the provided compounds increase the expression of TRAP1. TRAP1 has been reported to be a chaperone responsible for maintaining mitochondrial homeostasis and energy metabolism. As a chaperone, TRAP1 may be able to support the folding of proteins (e.g., in an ATP-dependent manner), stabilize proteins, and/or prevent aggregation of proteins (e.g., aggregation of proteins into nonfunctional structures). The provided compounds may also be able to support the folding of proteins (e.g., in an ATP-dependent manner), stabilize proteins, and/or prevent aggregation of proteins (e.g., aggregation of proteins into nonfunctional structures). The provided compounds may also be able to refold and/or solubilize aggregated or misfolded proteins (e.g., α-synuclein). The provided compounds may also be able to reduce the production of reactive oxygen species. The provided compounds may also increase the health, quality, function (e.g., mitochondrial respiration), quantity, and/or activity of mitochondria, and/or rescue dysfunction in mitochondria. The provided compounds may also be able to rescue the activity in PTEN-induced kinase 1 (“PINK1”) loss of function contexts.

Therefore, the provided compounds may be useful in treating or preventing diseases in a subject in need thereof. The disease may be associated with: decreased activity of TRAP1, decreased expression of TRAP1, protein misfolding, protein aggregation, increased production of reactive oxygen species, decreased health of mitochondria, decreased quality of mitochondria, reduced function of mitochondria, decreased quantity of mitochondria, and/or decreased activity of mitochondria. The subject may be a human.

“Heteroaryl” refers to a radical of a 5-10 membered monocyclic or bicyclic 4n+2 aromatic ring system (e.g., having 6 or 10 π electrons shared in a cyclic array) having ring carbon atoms and 1-4 ring heteroatoms provided in the aromatic ring system, wherein each heteroatom is independently selected from nitrogen, oxygen and sulfur (“5-10 membered heteroaryl”). In heteroaryl groups that contain one or more nitrogen atoms, the point of attachment can be a carbon or nitrogen atom, as valency permits. Heteroaryl bicyclic ring systems can include one or more heteroatoms in one or both rings. “Heteroaryl” includes ring systems wherein the heteroaryl ring, as defined above, is fused with one or more carbocyclyl or heterocyclyl groups wherein the point of attachment is on the heteroaryl ring, and in such instances, the number of ring members continue to designate the number of ring members in the heteroaryl ring system. “Heteroaryl” also includes ring systems wherein the heteroaryl ring, as defined above, is fused with one or more aryl groups wherein the point of attachment is either on the aryl or heteroaryl ring, and in such instances, the number of ring members designates the number of ring members in the fused (aryl/heteroaryl) ring system. Bicyclic heteroaryl groups wherein one ring does not contain a heteroatom (e.g., indolyl, quinolinyl, carbazolyl, and the like) the point of attachment can be on either ring, e.g., either the ring bearing a heteroatom (e.g., 2-indolyl) or the ring that does not contain a heteroatom (e.g., 5-indolyl).

In some embodiments, a heteroaryl group is a 5-10 membered aromatic ring system having ring carbon atoms and 1-4 ring heteroatoms provided in the aromatic ring system, wherein each heteroatom is independently selected from nitrogen, oxygen, and sulfur (“5-10 membered heteroaryl”). In some embodiments, a heteroaryl group is a 5-8 membered aromatic ring system having ring carbon atoms and 1-4 ring heteroatoms provided in the aromatic ring system, wherein each heteroatom is independently selected from nitrogen, oxygen, and sulfur (“5-8 membered heteroaryl”). In some embodiments, a heteroaryl group is a 5-6 membered aromatic ring system having ring carbon atoms and 1-4 ring heteroatoms provided in the aromatic ring system, wherein each heteroatom is independently selected from nitrogen, oxygen, and sulfur (“5-6 membered heteroaryl”). In some embodiments, the 5-6 membered heteroaryl has 1-3 ring heteroatoms selected from nitrogen, oxygen, and sulfur. In some embodiments, the 5-6 membered heteroaryl has 1-2 ring heteroatoms selected from nitrogen, oxygen, and sulfur. In some embodiments, the 5-6 membered heteroaryl has 1 ring heteroatom selected from nitrogen, oxygen, and sulfur. Unless otherwise specified, each instance of a heteroaryl group is independently optionally substituted, e.g., unsubstituted (“unsubstituted heteroaryl”) or substituted (“substituted heteroaryl”) with one or more substituents. In certain embodiments, the heteroaryl group is unsubstituted 5-14 membered heteroaryl. In certain embodiments, the heteroaryl group is substituted 5-14 membered heteroaryl.

“Partially unsaturated” refers to a group that includes at least one double or triple bond. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aromatic groups (e.g., aryl or heteroaryl groups) as herein defined. Likewise, “saturated” refers to a group that does not contain a double or triple bond, i.e., contains all single bonds.

In some embodiments, aliphatic, alkyl, alkenyl, alkynyl, carbocyclyl, heterocyclyl, aryl, and heteroaryl groups, as defined herein, are optionally substituted (e.g., “substituted” or “unsubstituted” alkyl, “substituted” or “unsubstituted” alkenyl, “substituted” or “unsubstituted” alkynyl, “substituted” or “unsubstituted” carbocyclyl, “substituted” or “unsubstituted” heterocyclyl, “substituted” or “unsubstituted” aryl or “substituted” or “unsubstituted” heteroaryl group). In general, the term “substituted”, whether preceded by the term “optionally” or not, means that at least one hydrogen present on a group (e.g., a carbon or nitrogen atom) is replaced with a permissible substituent, e.g., a substituent which upon substitution results in a stable compound, e.g., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction. Unless otherwise indicated, a “substituted” group has a substituent at one or more substitutable positions of the group, and when more than one position in any given structure is substituted, the substituent is either the same or different at each position. The term “substituted” is contemplated to include substitution with all permissible substituents of organic compounds, any of the substituents described herein that results in the formation of a stable compound. The present disclosure contemplates any and all such combinations in order to arrive at a stable compound. For purposes of this disclosure, heteroatoms such as nitrogen may have hydrogen substituents and/or any suitable substituent as described herein which satisfy the valencies of the heteroatoms and results in the formation of a stable moiety.

“Pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and other animals without undue toxicity, irritation, allergic response, and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences (1977) 66:1-19. Pharmaceutically acceptable salts of the compounds describe herein include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(C_1-4alkyl)₄ salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, quaternary salts.

The term “solvate” refers to forms of the compound that are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, and the like. The provided compounds may be prepared, e.g., in crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. “Solvate” encompasses both solution-phase and isolable solvates. Representative solvates include hydrates, ethanolates, and methanolates.

The term “hydrate” refers to a compound that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, a hydrate of a compound may be represented, for example, by the general formula R.xH₂O, wherein R is the compound and wherein x is a number greater than 0. A given compound may form more than one type of hydrates, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R.0.5H₂O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R.2H₂O) and hexahydrates (R.6H₂O)).

The term “tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of 7 electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenylnitromethane, that are likewise formed by treatment with acid or base.

Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.

It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”.

Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.

The term “polymorphs” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof) in a particular crystal packing arrangement. All polymorphs have the same elemental composition. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, rate of crystallization, storage temperature, and other factors may cause one crystal form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.

The term “prodrugs” refer to compounds, including derivatives of the provided compounds, which have cleavable groups and become by solvolysis or under physiological conditions the provided compounds which are pharmaceutically active in vivo. Such examples include, but are not limited to, ester derivatives and the like. Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but in the acid sensitive form often offers advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides. Simple aliphatic or aromatic esters, amides, and anhydrides derived from acidic groups pendant on the compounds of this invention are particular prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkylesters. C₁ to C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, aryl, C₇-C₁₂ substituted aryl, and C₇-C₁₂ arylalkyl esters of the provided compounds may be preferred.

In humans, the Ensembl of the TRAP1 gene is ENSG00000126602. See, e.g., Song et al., The Journal Of Biological Chemistry, 1995, Vol. 270, No. 8, pp. 3574-3581; Felts et al., The Journal Of Biological Chemistry, 2000, Vol. 275, No. 5, pp. 3305-3312.

“PINK1,” or “PTEN-induced kinase 1,” is a mitochondrial serine/threonine-protein kinase encoded by the PINK1 gene. In humans, the Ensembl of the PINK1 gene is ENSG00000158828. See, e.g., Unoki et al., Oncogene, 2001, 20(33):4457-65; Valente et al., Ann. Neurol., 2004, 56(3):336-41.

A “subject” to which administration is contemplated includes, but is not limited to, humans (i.e., a male or female of any age group, e.g., a pediatric subject (e.g., infant, child, adolescent) or adult subject (e.g., young adult, middle-aged adult, or senior adult)) and/or other non-human animals, for example, mammals (e.g., primates (e.g., cynomolgus monkeys, rhesus monkeys); commercially relevant mammals such as cattle, pigs, horses, sheep, goats, cats, and/or dogs) and birds (e.g., commercially relevant birds such as chickens, ducks, geese, and/or turkeys). In certain embodiments, the subject is a mammal. The subject may be a male or female and at any stage of development. A non-human animal may be a transgenic animal.

The term “biological sample” refers to any sample including tissue samples (such as tissue sections and needle biopsies of a tissue); cell samples (e.g., cytological smears (such as Pap or blood smears) or samples of cells obtained by microdissection); samples of whole organisms (such as samples of yeasts or bacteria); or cell fractions, fragments or organelles (such as obtained by lysing cells and separating the components thereof by centrifugation or otherwise). Other examples of biological samples include blood, serum, urine, semen, fecal matter, cerebrospinal fluid, interstitial fluid, mucous, tears, sweat, pus, biopsied tissue (e.g., obtained by a surgical biopsy or needle biopsy), nipple aspirates, milk, vaginal fluid, saliva, swabs (such as buccal swabs), or any material containing biomolecules that is derived from a first biological sample.

The terms “administer,” “administering,” or “administration,” refers to implanting, absorbing, ingesting, injecting, inhaling, or otherwise introducing a compound, or a pharmaceutical composition thereof.

The terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a “pathological condition” (e.g., a disease, disorder, or condition, or one or more signs or symptoms thereof) described herein. In some embodiments, treatment may be administered after one or more signs or symptoms have developed or have been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of the disease or condition. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example, to delay or prevent recurrence.

The term “prevent,” “preventing,” or “prevention” refers to a prophylactic treatment of a subject who is not and was not with a disease but is at risk of developing the disease or who was with a disease, is not with the disease, but is at risk of regression of the disease. In certain embodiments, the subject is at a higher risk of developing the disease or at a higher risk of regression of the disease than an average healthy member of a population of subjects.

The terms “condition,” “disease,” and “disorder” are used interchangeably.

An “effective amount” of a provided compound refers to an amount sufficient to elicit the desired biological response, i.e., treating the condition. As will be appreciated by those of ordinary skill in this art, the effective amount of a provided compound may vary depending on such factors as the desired biological endpoint, the pharmacokinetics of the compound, the condition being treated, the mode of administration, and the age and health of the subject. An effective amount encompasses therapeutic and prophylactic treatment. For example, in treating cancer, an effective amount of a compound may reduce the tumor burden or stop the growth or spread of a tumor.

A “therapeutically effective amount” of a provided compound is an amount sufficient to provide a therapeutic benefit in the treatment of a condition or to delay or minimize one or more symptoms associated with the condition. A therapeutically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment of the condition. The term “therapeutically effective amount” can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of the condition, or enhances the therapeutic efficacy of another therapeutic agent.

A “prophylactically effective amount” of a provided compound is an amount sufficient to prevent a condition, or one or more symptoms associated with the condition or prevent its recurrence. A prophylactically effective amount of a compound means an amount of a therapeutic agent, alone or in combination with other agents, which provides a prophylactic benefit in the prevention of the condition. The term “prophylactically effective amount” can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.

The term “genetic disease” refers to a disease caused by one or more abnormalities in the genome of a subject, such as a disease that is present from birth of the subject. Genetic diseases may be heritable and may be passed down from the parents' genes. A genetic disease may also be caused by mutations or changes of the DNAs and/or RNAs of the subject. In such cases, the genetic disease will be heritable if it occurs in the germline. Exemplary genetic diseases include Aarskog-Scott syndrome, Aase syndrome, achondroplasia, acrodysostosis, addiction, adreno-leukodystrophy, albinism, ablepharon-macrostomia syndrome, alagille syndrome, alkaptonuria, alpha-1 antitrypsin deficiency, Alport's syndrome, Alzheimer's disease, asthma, autoimmune polyglandular syndrome, androgen insensitivity syndrome, Angelman syndrome, ataxia, ataxia telangiectasia, atherosclerosis, attention deficit hyperactivity disorder (ADHD), autism, baldness, Batten disease, Beckwith-Wiedemann syndrome, Best disease, bipolar disorder, brachydactyl), breast cancer, Burkitt lymphoma, chronic myeloid leukemia, Charcot-Marie-Tooth disease, Crohn's disease, cleft lip, Cockayne syndrome, Coffin Lowry syndrome, colon cancer, congenital adrenal hyperplasia, Cornelia de Lange syndrome, Costello syndrome, Cowden syndrome, craniofrontonasal dysplasia, Crigler-Najjar syndrome, Creutzfeldt-Jakob disease, cystic fibrosis, deafness, depression, diabetes, diastrophic dysplasia, DiGeorge syndrome, Down's syndrome, dyslexia, Duchenne muscular dystrophy, Dubowitz syndrome, ectodermal dysplasia Ellis-van Creveld syndrome, Ehlers-Danlos, epidermolysis bullosa, epilepsy, essential tremor, familial hypercholesterolemia, familial Mediterranean fever, fragile X syndrome, Friedreich's ataxia, Gaucher's disease, glaucoma, glucose galactose malabsorption, glutaricaciduria, gyrate atrophy, Goldberg Shprintzen syndrome (velocardiofacial syndrome), Gorlin syndrome, Hailey-Hailey disease, hemihypertrophy, hemochromatosis, hemophilia, hereditary motor and sensory neuropathy (HMSN), hereditary non polyposis colorectal cancer (HNPCC), Huntington's disease, immunodeficiency with hyper-IgM, juvenile onset diabetes, Klinefelter's syndrome, Kabuki syndrome, Leigh's disease, long QT syndrome, lung cancer, malignant melanoma, manic depression, Marfan syndrome, Menkes syndrome, miscarriage, mucopolysaccharide disease, multiple endocrine neoplasia, multiple sclerosis, muscular dystrophy, myotrophic lateral sclerosis, myotonic dystrophy, neurofibromatosis, Niemann-Pick disease, Noonan syndrome, obesity, ovarian cancer, pancreatic cancer, Parkinson's disease, paroxysmal nocturnal hemoglobinuria, Pendred syndrome, peroneal muscular atrophy, phenylketonuria (PKU), polycystic kidney disease, Prader-Willi syndrome, primary biliary cirrhosis, prostate cancer, REAR syndrome, Refsum disease, retinitis pigmentosa, retinoblastoma, Rett syndrome, Sanfilippo syndrome, schizophrenia, severe combined immunodeficiency, sickle cell anemia, spina bifida, spinal muscular atrophy, spinocerebellar atrophy, sudden adult death syndrome, Tangier disease, Tay-Sachs disease, thrombocytopenia absent radius syndrome, Townes-Brocks syndrome, tuberous sclerosis, Turner syndrome, Usher syndrome, von Hippel-Lindau syndrome, Waardenburg syndrome, Weaver syndrome, Werner syndrome, Williams syndrome, Wilson's disease, xeroderma piginentosum, and Zellweger syndrome.

A “proliferative disease” refers to a disease that occurs due to abnormal growth or extension by the multiplication of cells (Walker, Cambridge Dictionary of Biology; Cambridge University Press: Cambridge, UK, 1990). A proliferative disease may be associated with: 1) the pathological proliferation of normally quiescent cells; 2) the pathological migration of cells from their normal location (e.g., metastasis of neoplastic cells); 3) the pathological expression of proteolytic enzymes such as the matrix metalloproteinases (e.g., collagenases, gelatinases, and elastases); or 4) the pathological angiogenesis as in proliferative retinopathy and tumor metastasis. Exemplary proliferative diseases include cancers (i.e., “malignant neoplasms”), benign neoplasms, angiogenesis, inflammatory diseases, and autoimmune diseases.

The term “angiogenesis” refers to the physiological process through which new blood vessels form from pre-existing vessels. Angiogenesis is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in a developing embryo form through vasculogenesis, after which angiogenesis is responsible for most blood vessel growth during normal or abnormal development. Angiogenesis is a vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. However, angiogenesis is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer. Angiogenesis may be chemically stimulated by angiogenic proteins, such as growth factors (e.g., VEGF). “Pathological angiogenesis” refers to abnormal (e.g., excessive or insufficient) angiogenesis that amounts to and/or is associated with a disease.

The terms “neoplasm” and “tumor” are used herein interchangeably and refer to an abnormal mass of tissue wherein the growth of the mass surpasses and is not coordinated with the growth of a normal tissue. A neoplasm or tumor may be “benign” or “malignant,” depending on the following characteristics: degree of cellular differentiation (including morphology and functionality), rate of growth, local invasion, and metastasis. A “benign neoplasm” is generally well differentiated, has characteristically slower growth than a malignant neoplasm, and remains localized to the site of origin. In addition, a benign neoplasm does not have the capacity to infiltrate, invade, or metastasize to distant sites. Exemplary benign neoplasms include lipoma, chondroma, adenomas, acrochordon, senile angiomas, seborrheic keratoses, lentigos, and sebaceous hyperplasias. In some cases, certain “benign” tumors may later give rise to malignant neoplasms, which may result from additional genetic changes in a subpopulation of the tumor's neoplastic cells, and these tumors are referred to as “pre-malignant neoplasms.” An exemplary pre-malignant neoplasm is a teratoma. In contrast, a “malignant neoplasm” is generally poorly differentiated (anaplasia) and has characteristically rapid growth accompanied by progressive infiltration, invasion, and destruction of the surrounding tissue. Furthermore, a malignant neoplasm generally has the capacity to metastasize to distant sites. The term “metastasis,” “metastatic,” or “metastasize” refers to the spread or migration of cancerous cells from a primary or original tumor to another organ or tissue and is typically identifiable by the presence of a “secondary tumor” or “secondary cell mass” of the tissue type of the primary or original tumor and not of that of the organ or tissue in which the secondary (metastatic) tumor is located. For example, a prostate cancer that has migrated to bone is said to be metastasized prostate cancer and includes cancerous prostate cancer cells growing in bone tissue.

The term “cancer” refers to a class of diseases characterized by the development of abnormal cells that proliferate uncontrollably and have the ability to infiltrate and destroy normal body tissues. See, e.g., Stedman's Medical Dictionary, 25th ed.; Hensyl ed.; Williams & Wilkins: Philadelphia, 1990. The cancer may be a solid tumor. The cancer may be a hematological malignancy. Exemplary cancers include acoustic neuroma; adenocarcinoma; adrenal gland cancer; anal cancer; angiosarcoma (e.g., lymphangiosarcoma, lymphangioendotheliosarcoma, hemangiosarcoma); appendix cancer; benign monoclonal gammopathy; biliary cancer (e.g., cholangiocarcinoma); bladder cancer; breast cancer (e.g., adenocarcinoma of the breast, papillary carcinoma of the breast, mammary cancer, medullary carcinoma of the breast); brain cancer (e.g., meningioma, glioblastomas, glioma (e.g., astrocytoma, oligodendroglioma), medulloblastoma); bronchus cancer; carcinoid tumor; cervical cancer (e.g., cervical adenocarcinoma); choriocarcinoma; chordoma; craniopharyngioma; colorectal cancer (e.g., colon cancer, rectal cancer, colorectal adenocarcinoma); connective tissue cancer; epithelial carcinoma; ependymoma; endotheliosarcoma (e.g., Kaposi's sarcoma, multiple idiopathic hemorrhagic sarcoma); endometrial cancer (e.g., uterine cancer, uterine sarcoma); esophageal cancer (e.g., adenocarcinoma of the esophagus, Barrett's adenocarcinoma); Ewing's sarcoma; ocular cancer (e.g., intraocular melanoma, retinoblastoma); familiar hypereosinophilia; gall bladder cancer; gastric cancer (e.g., stomach adenocarcinoma); gastrointestinal stromal tumor (GIST); germ cell cancer; head and neck cancer (e.g., head and neck squamous cell carcinoma, oral cancer (e.g., oral squamous cell carcinoma), throat cancer (e.g., laryngeal cancer, pharyngeal cancer, nasopharyngeal cancer, oropharyngeal cancer)); hematopoietic cancers (e.g., leukemia such as acute lymphocytic leukemia (ALL) (e.g., B-cell ALL, T-cell ALL), acute myelocytic leukemia (AML) (e.g., B-cell AML, T-cell AML), chronic myelocytic leukemia (CML) (e.g., B-cell CML, T-cell CML), and chronic lymphocytic leukemia (CLL) (e.g., B-cell CLL, T-cell CLL)); lymphoma such as Hodgkin lymphoma (HL) (e.g., B-cell HL, T-cell HL) and non-Hodgkin lymphoma (NHL) (e.g., B-cell NHL such as diffuse large cell lymphoma (DLCL) (e.g., diffuse large B-cell lymphoma), follicular lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma (MCL), marginal zone B-cell lymphomas (e.g., mucosa-associated lymphoid tissue (MALT) lymphomas, nodal marginal zone B-cell lymphoma, splenic marginal zone B-cell lymphoma), primary mediastinal B-cell lymphoma, Burkitt lymphoma, lymphoplasmacytic lymphoma (i.e., Waldenström's macroglobulinemia), hairy cell leukemia (HCL), immunoblastic large cell lymphoma, precursor B-lymphoblastic lymphoma and primary central nervous system (CNS) lymphoma; and T-cell NHL such as precursor T-lymphoblastic lymphoma/leukemia, peripheral T-cell lymphoma (PTCL) (e.g., cutaneous T-cell lymphoma (CTCL) (e.g., mycosis fungoides, Sezary syndrome), angioimmunoblastic T-cell lymphoma, extranodal natural killer T-cell lymphoma, enteropathy type T-cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, and anaplastic large cell lymphoma); a mixture of one or more leukemia/lymphoma as described above; and multiple myeloma (MM)), heavy chain disease (e.g., alpha chain disease, gamma chain disease, mu chain disease); hemangioblastoma; hypopharynx cancer; inflammatory myofibroblastic tumors; immunocytic amyloidosis; kidney cancer (e.g., nephroblastoma a.k.a.

An “autoimmune disease” refers to a disease arising from an inappropriate immune response of the body of a subject against substances and tissues normally present in the body. In other words, the immune system mistakes some part of the body as a pathogen and attacks its own cells. This may be restricted to certain organs (e.g., in autoimmune thyroiditis) or involve a particular tissue in different places (e.g., Goodpasture's disease which may affect the basement membrane in both the lung and kidney). The treatment of autoimmune diseases is typically with immunosuppression, e.g., medications which decrease the immune response.

Besides inert diluents, the oral pharmaceutical compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. In certain embodiments for parenteral administration, the conjugates are mixed with solubilizing agents such as Cremophor®, alcohols, oils, modified oils, glycols, polysorbates, cyclodextrins, polymers, and mixtures thereof.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension, or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P., and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or di-glycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid pharmaceutical compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form may be accomplished by dissolving or suspending the drug in an oil vehicle.

Pharmaceutical compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol, or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (f) absorption accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonite clay, and (i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets, and pills, the dosage form may include a buffering agent.

Solid pharmaceutical compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the art of pharmacology. They may optionally comprise opacifying agents and can be of a pharmaceutical composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of encapsulating pharmaceutical compositions which can be used include polymeric substances and waxes. Solid pharmaceutical compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

The active ingredient can be in a micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings, and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active ingredient can be admixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms may comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may comprise buffering agents. They may optionally comprise opacifying agents and can be of a pharmaceutical composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of encapsulating agents which can be used include polymeric substances and waxes.

Dosage forms for topical and/or transdermal administration of a provided compound may include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants, and/or patches. Generally, the active ingredient is admixed under sterile conditions with a pharmaceutically acceptable carrier or excipient and/or any needed preservatives and/or buffers as can be required. Additionally, the present disclosure contemplates the use of transdermal patches, which often have the added advantage of providing controlled delivery of an active ingredient to the body. Such dosage forms can be prepared, for example, by dissolving and/or dispensing the active ingredient in the proper medium. Alternatively or additionally, the rate can be controlled by either providing a rate controlling membrane and/or by dispersing the active ingredient in a polymer matrix and/or gel.

Suitable devices for use in delivering intradermal pharmaceutical compositions include short needle devices. Intradermal pharmaceutical compositions can be administered by devices which limit the effective penetration length of a needle into the skin. Alternatively or additionally, conventional syringes can be used in the classical mantoux method of intradermal administration. Jet injection devices which deliver liquid formulations to the dermis via a liquid jet injector and/or via a needle which pierces the stratum corneum and produces a jet which reaches the dermis are suitable. Ballistic powder/particle delivery devices which use compressed gas to accelerate the provided compound in powder form through the outer layers of the skin to the dermis are suitable.

Formulations suitable for topical administration include, but are not limited to, liquid and/or semi-liquid preparations such as liniments, lotions, oil-in-water and/or water-in-oil emulsions such as creams, ointments, and/or pastes, and/or solutions and/or suspensions. Topically administrable formulations may, for example, comprise from about 1% to about 10% (w/w) active ingredient, although the concentration of the active ingredient can be as high as the solubility limit of the active ingredient in the solvent. Formulations for topical administration may further comprise one or more of the additional ingredients.

A pharmaceutical composition can be prepared, packaged, and/or sold in a formulation suitable for pulmonary administration via the buccal cavity. Such a formulation may comprise dry particles which comprise the active ingredient and which have a diameter in the range from about 0.5 to about 7 nanometers, or from about 1 to about 6 nanometers. Such pharmaceutical compositions are conveniently in the form of dry powders for administration using a device comprising a dry powder reservoir to which a stream of propellant can be directed to disperse the powder and/or using a self-propelling solvent/powder dispensing container such as a device comprising the active ingredient dissolved and/or suspended in a low-boiling propellant in a sealed container. Such powders comprise particles wherein at least 98% of the particles by weight have a diameter greater than 0.5 nanometers and at least 95% of the particles by number have a diameter less than 7 nanometers. Alternatively, at least 95% of the particles by weight have a diameter greater than 1 nanometer and at least 90% of the particles by number have a diameter less than 6 nanometers. Dry powder pharmaceutical compositions may include a solid fine powder diluent such as sugar and are conveniently provided in a unit dose form.

Low boiling propellants generally include liquid propellants having a boiling point of below 65° F. at atmospheric pressure. Generally the propellant may constitute 50 to 99.9% (w/w) of the pharmaceutical composition, and the active ingredient may constitute 0.1 to 20% (w/w) of the pharmaceutical composition. The propellant may further comprise additional ingredients such as a liquid non-ionic and/or solid anionic surfactant and/or a solid diluent (which may have a particle size of the same order as particles comprising the active ingredient).

Pharmaceutical compositions formulated for pulmonary delivery may provide the active ingredient in the form of droplets of a solution and/or suspension. Such formulations can be prepared, packaged, and/or sold as aqueous and/or dilute alcoholic solutions and/or suspensions, optionally sterile, comprising the active ingredient, and may conveniently be administered using any nebulization and/or atomization device. Such formulations may further comprise one or more additional ingredients including, but not limited to, a flavoring agent such as saccharin sodium, a volatile oil, a buffering agent, a surface active agent, and/or a preservative such as methylhydroxybenzoate. The droplets provided by this route of administration may have an average diameter in the range from about 0.1 to about 200 nanometers.

Formulations as being useful for pulmonary delivery are useful for intranasal delivery of a pharmaceutical composition. Another formulation suitable for intranasal administration is a coarse powder comprising the active ingredient and having an average particle from about 0.2 to 500 micrometers. Such a formulation is administered by rapid inhalation through the nasal passage from a container of the powder held close to the nares.

Formulations for nasal administration may, for example, comprise from about as little as 0.1% (w/w) to as much as 100% (w/w) of the active ingredient, and may comprise one or more of the additional ingredients. A pharmaceutical composition can be prepared, packaged, and/or sold in a formulation for buccal administration. Such formulations may, for example, be in the form of tablets and/or lozenges made using conventional methods, and may contain, for example, 0.1 to 20% (w/w) active ingredient, the balance comprising an orally dissolvable and/or degradable pharmaceutical composition and, optionally, one or more of the additional ingredients. Alternately, formulations for buccal administration may comprise a powder and/or an aerosolized and/or atomized solution and/or suspension comprising the active ingredient. Such powdered, aerosolized, and/or aerosolized formulations, when dispersed, may have an average particle and/or droplet size in the range from about 0.1 to about 200 nanometers, and may further comprise one or more of the additional ingredients.

A pharmaceutical composition can be prepared, packaged, and/or sold in a formulation for ophthalmic administration. Such formulations may, for example, be in the form of eye drops including, for example, a 0.1-1.0% (w/w) solution and/or suspension of the active ingredient in an aqueous or oily liquid carrier or excipient. Such drops may further comprise buffering agents, salts, and/or one or more other of the additional ingredients. Other ophthalmically-administrable formulations which are useful include those which comprise the active ingredient in microcrystalline form and/or in a liposomal preparation. Ear drops and/or eye drops are also contemplated as being within the scope of this disclosure.

In another aspect, the present disclosure provides methods of increasing the expression and/or activity of TRAP1 in a subject in need thereof, the methods comprising administering to the subject in need thereof an effective amount of a provided compound or pharmaceutical composition. In certain embodiments, the activity of TRAP1 is the ATPase activity of TRAP1.

In another aspect, the present disclosure provides methods of increasing the health, quality, function, quantity, and/or activity of mitochondria in a cell, tissue, or biological sample, the methods comprising contacting the cell, tissue, or biological sample with an effective amount of a provided compound or pharmaceutical composition.

The provided compounds and pharmaceutical compositions may also be useful for treating or preventing a disease in a subject in need thereof. It has been reported that that PINK1 may protect against oxidative-stress-induced cell death by suppressing cytochrome c release from mitochondria, and this protective action of PINK1 may depend on its kinase activity to phosphorylate TRAP1 (Pridgeon et al., PLoS Biol., 2007, 5, e172). Moreover, the ability of PINK1 to promote TRAP1 phosphorylation and cell survival may be impaired by of Parkinson's disease linked PINK1 G309D, L347P, and W437X mutations. See, id. PINK1 may phosphorylate downstream effector TRAP1 to prevent oxidative-stress-induced apoptosis. See, id.

It has been reported that that TRAP1 may work downstream of PINK1 and in parallel with parkin in Drosophila, and that enhancing its function may ameliorate mitochondrial dysfunction and rescue neurodegeneration in Parkinson's disease (Costa et al., Cell Death and Disease (2013) 4, e467).

It has been reported that in certain human cell models, TRAP1 overexpression may be protective, rescuing HTRA2 and PINK1-associated mitochondrial dysfunction, that TRAP1 may act downstream of HTRA2 and PINK1, and that TRAP1 loss of function may lead to reduced control of energy metabolism, ultimately impacting mitochondrial membrane potential (Fitzgerald et al., Brain 2017: 140; 2444-2459).

It has been reported that that [A53T]α-Synuclein toxicity may be intimately connected to mitochondrial dysfunction, and that toxicity reduction in fly and rat primary neurons and human cell lines may be achieved using overexpression of the mitochondrial chaperone TRAP1 (Butler et al., PLoS Genetics, 2012, volume 8, issue 2, e1002488). α-Synuclein may be a causal factor in Parkinson's disease pathogenesis. See id.

It has been reported that mitochondria are intimately involved in the regulation of calcium homeostasis, stress response, and cell death pathways, that an impairment of mitochondrial function results in cellular damage and is linked to aging and neurodegeneration, that mitochondrial dysfunction plays a central role in the pathogenesis of Parkinson's disease, and that several Parkinson's disease-associated genes interface with pathways regulating mitochondrial function, morphology, and dynamics (Winklhofer et al., Biochimica et Biophysica Acta, 1802 (2010) 29-44).

It has been reported that there is overwhelming evidence of impaired mitochondrial function as a causative factor in neurodegenerative diseases, that evidence has emerged for impaired mitochondrial dynamics (e.g., shape, size, fission-fusion, distribution, movement etc.) in neurodegenerative diseases such as Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Alzheimer's disease, and Friedreich's ataxia.

It has been reported that mitochondrial dysfunction is not only observed in monogenic mitochondrial disorders but is also associated with more common pathologic conditions, such as Alzheimer's disease, Parkinson's disease, cancer, cardiac disease, diabetes, epilepsy, Huntington's disease, and obesity (Koopman et al., The New England Journal of Medicine, 2012, 366, 1132-1141).

It has been reported that some mitochondrial disorders only affect a single organ (e.g., the eye in Leber hereditary optic neuropathy [LHON]), many other mitochondrial disorders involve multiple organ systems and often present with prominent neurologic and myopathic features (Chinnery P F. Mitochondrial Disorders Overview. 2000 Jun. 8 [Updated 2014 Aug. 14]. In: Adam M P, Ardinger H H, Pagon R A, et al., editors. GeneReviews® [Internet]. Seattle (Wash.): University of Washington, Seattle; 1993-2020). Chinnery also discloses that many individuals with a mutation of mtDNA display a cluster of clinical features that fall into a discrete clinical syndrome, such as the Kearns-Sayre syndrome (KSS), chronic progressive external ophthalmoplegia (CPEO), mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS), myoclonic epilepsy with ragged-red fibers fibers fibers (MERRF), neurogenic weakness with ataxia and retinitis pigmentosa (NARP), or Leigh syndrome (LS). Chinnery also discloses that considerable clinical variability exists, and many individuals do not fit neatly into one particular category, which is well-illustrated by the overlapping spectrum of disease phenotypes (including mitochondrial recessive ataxia syndrome (MIRAS)). Chinnery also discloses that common clinical features of mitochondrial disease—whether involving a mitochondrial or nuclear gene—include ptosis, external ophthalmoplegia, proximal myopathy and exercise intolerance, cardiomyopathy, sensorineural deafness, optic atrophy, pigmentary retinopathy, and diabetes mellitus. Common central nervous system findings are fluctuating encephalopathy, seizures, dementia, migraine, stroke-like episodes, ataxia, and spasticity.

Ng et al., J Neurol (2016) 263:179-191 discloses the genetics and management of mitochondrial diseases, e.g., mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS); myoclonic epilepsy with ragged red fibres (MERRF); mitochondrial neuro-gastrointestinal involvement and encephalopathy (MNGIE); neuropathy, ataxia, and retinitis pigmentosa (NARP); chronic progressive external ophthalmoplegia (CPEO); Alpers disease; Pearson syndrome; Leigh disease; Sengers syndrome; and Kearns-Sayre syndrome.

It has been reported that three very-highly conserved variants, p. Ile253Val, p.Glu192Lys, and p.Arg128His, in the ATPase domain of the TRAP1 gene may be associated with a statistically-significant, several-fold increased, prevalence of common chronic functional conditions, including at least pain, fatigue, and GI dysmotility (Boles et al., Mitochondrion 23 (2015) 64-70). These variants may be an important factor in the etiology of functional symptomatology. See, id.

It has been reported that mutations in TRAP1 may cause congenital abnormalities of the kidney and urinary tract (CAKUT) CAKUT or VACTERL association with CAKUT (Saisawat et al., Kidney International (2014) 85, 1310-1317).

Example 2. ADP Glo Assay

Potency of test compounds to modulate the ATPase activity of TRAP1 enzyme was evaluated using ADP Glo assay. The assay is based on quantification of the ADP generated from ATP in the ATPase reaction. The assay is performed in two steps; first, after the ATPase reaction an equal volume of ADP-Glo™ Reagent is added to terminate the ATPase reaction and deplete the remaining ATP. Second, the Kinase Detection Reagent is added to simultaneously convert ADP to ATP and allow the newly synthesized ATP to be measured using a luciferase/luciferin reaction.

All the assays were carried out in a 384-well Proxiplate. The buffer used was 25 mM Pipes pH-7.5, 40 mM KCl, 0.05 mM MgCl₂, 0.025% BSA, 0.316 mM EGTA, 0.003% Empigen, 0.01% Igepal. 150 nM Trap1 enzyme was incubated with various concentrations of the test compound (0.79 μM-100 μM) at 37° C. for 30 mins (except in blank wells). 20 μM ATP was added to each well to start the reaction. The plate was spun for 1 min at 1200 rpm and then incubated at 37° C. for 60 mins. 5 μl of ADP Glo reagent was added to all the wells and spun the plate for 1 min at 1200 rpm and kept it on a shaker at ambient temperature for 60 mins. 10 μl of kinase detection mix was added to all the wells and the plate was read for Luminescence at 495 nm. The amount of ADP released was estimated from ATP/ADP standard curve generated at the same experimental conditions. E_max (Maximal percent activation) and EC₅₀ (concentration for half maximal activation) were estimated by fitting the dose response data to a sigmoidal curve fitting equation using Graphpad Prism software V. 8. Exemplary results are shown in Table 2. Exemplary percent activation values at a compound concentration of 50 μM are shown in Table 2A.

Example 3. Malachite Green Phosphate Assay

The Potency of test compounds to modulate the ATPase activity of TRAP1 enzyme was evaluated using malachite green phosphatase assay. The assay is based on quantification of the green complex formed between Malachite Green, molybdate and inorganic phosphate generated in the phosphatase reaction. Assays were performed using a Malachite Green assay kit. All the assays were carried out in a 96-well transparent plate. The buffer used was 50 mM HEPES (pH 7.5), 20 mM KCl, 4 mM MgCl₂ and 0.05% BSA. 150 nM Trap1 enzyme was incubated with various concentrations of the test compound (0.78 μM-100 μM) at 37° C. for 30 mins. 20 μM ATP was added to each well (except blank wells) to start the reaction and the plate was then incubated at 37° C. for 180 mins. 10 μl of the reaction volume of each sample was then transferred to a white 384-well proxiplate in quadruplets. 2.5 μl of Malachite Green reagent was added to all the wells and the plate was equilibrated for 15 mins. The reaction was stopped by adding 12% H₂SO₄ and the plate was read for fluorescence at 620 nm (λ_ex=573 nm). The amount of phosphate released was estimated from a phosphate standard curve generated at the same experimental conditions. E_max (Maximal percent activation) and EC₅₀ (concentration of test compound for half maximal activation) were estimated by fitting the dose response data to a sigmoidal curve fitting equation using Graphpad Prism software V.7.0. Exemplary results are shown in Table 2.

Example 6. Effects of Compounds on ROS Production in Primary Rat Dopaminergic TH-Positive Neurons

Primary Culture of Mesencephalic Neurons

All experiments were carried out in accordance with the National Institutes of Health Guide for the Care and Use of Laboratory Animals and followed current European Union regulations (Directive 2010/63/EU). Agreement number: A1301310.

Rat dopaminergic neurons were cultured as described by Visanji et al., 2008. Briefly, pregnant female rat of 15 days of gestation are sacrificed using a deep anesthesia with CO₂ chamber and a cervical dislocation. The midbrains obtained from 15-day-old rat embryos are dissected under a microscope. The embryonic midbrains are removed and placed in ice-cold medium of Leibovitz (L15) containing 2% of Penicillin-Streptomycin (PS) and 1% of bovine serum albumin (BSA). The ventral portion of the mesencephalic flexure, a region of the developing brain rich in dopaminergic neurons, is used for the cell preparations.

The midbrains are dissociated by trypsinisation for 20 min at 37° C. (solution at a final concentration of 0.05% trypsin and 0.02% EDTA). The reaction is stopped by the addition of Dulbecco's modified Eagle's medium (DMEM) containing DNAase I grade II (0.5 mg/mL) and 10% of foetal calf serum (FCS). Cells are then mechanically dissociated by 3 passages through a 10 mL pipette. Cells are then centrifuged at 180×g for 10 min at +4° C. on a layer of BSA (3.5%) in L15 medium. The supernatant is discarded and the cell pellets re-suspended in a defined culture medium consisting of Neurobasal supplemented with B27 (2%), L-glutamine (2 mM) and 2% of PS solution and 10 ng/mL of Brain-derived neurotrophic factor (BDNF) and 1 ng/mL of Glial-Derived Neurotrophic Factor (GDNF). Viable cells are counted in a Neubauer cytometer using the trypan blue exclusion test. The cells are seeded at a density of 40,000 cells/well in 96 well-plates (pre-coated with poly-L-lysine) and maintained in a humidified incubator at 37° C. in 5% C_02/95% air atmosphere. Half of the medium is changed every 2 days with fresh medium. To avoid any edge effect, the first and last columns as well as first and last lines of culture plates are not used in the study. Briefly, on day 4 of culture, the medium is removed, and fresh medium added, without or with compounds, as well as ferulic acid. On day 6 the toxin is added for 4 h or 24 h diluted in control medium, in presence of the compounds. Six wells per condition are assessed.

Test Compounds and 6OHDA and MPP+ Exposure

Pre-incubation: On day 4 of culture, the compounds and the reference compound (ferulic acid) are dissolved in culture medium and then pre-incubated with mesencephalic neurons for 48 hours before the toxin application (plate 1 and plate 2). Ferulic acid (10 PM) is used as a reference positive control for its anti-oxidative properties. Injury: 48 hours after the application of the test compounds (on day 6), 6OHDA (20 μM) is diluted in culture medium, in presence of the compounds and added to the culture for 4 hours (plate 1) or 24 hours (plate 2). For plate 1, the culture is stopped after the 4-hour injury. For plate 2, the culture medium is removed after 24 hours and replaced with fresh medium, without 6-OHDA and without the compounds, for an additional 24 hours.

End Point Evaluation

Immunostaining: TH and ROS—plate 1

4 hours (plate 1) after injury, the cell culture supernatant is removed, and the live cells are incubated with CellROX green reagent (marker of ROS production) for 30 min at 37° C. The CellROX reagent is cell-penetrant and will become fluorescent once oxidized by ROS. Then, cells are fixed by a solution of 4% paraformaldehyde in PBS, pH=7.3 for 20 min at room temperature. The cells are washed twice in PBS, and then are permeabilized and non-specific sites are blocked with a solution of PBS containing 0.1% of saponin and 1% FCS for 15 min at room temperature. Then, the cultures are incubated with a monoclonal Anti-Tyrosine Hydroxylase (TH) antibody produced in mouse at dilution of 1/10000 in PBS containing 1% FCS, 0.1% saponin, for 2 hours at room temperature. This antibody will be revealed with Alexa Fluor 568 goat anti-mouse IgG at the dilution 1/800 in PBS containing 1% FCS, 0.1% saponin, for 1 h at room temperature.

Immunostaining: TH and Caspase 3—Plate 2

48 hours (24 h injury+24 h recovery) after the injury, the cell culture supernatant is removed, and cells are fixed by a solution of 4% paraformaldehyde in PBS, pH=7.3 for 20 min at room temperature. The cells are washed twice in PBS, and then are permeabilized and non-specific sites blocked with a solution of PBS containing 0.1% of saponin and 1% FCS for 15 min at room temperature. Then, the cultures are incubated with i) a monoclonal Anti-Tyrosine Hydroxylase (TH) antibody produced in mouse at dilution of 1/10000 and ii) a rabbit polyclonal antibody anti-activated caspase 3 at dilution of 1/500 in PBS containing 1% fetal calf serum and 0.1% of saponin, for 2 hours at room temperature. These antibodies will be revealed with Alexa Fluor 488 goat anti-mouse IgG and Alexa fluor 568 goat anti-rabbit IgG at the dilution 1/400 in PBS containing 1% FCS, 0.1% saponin, for 1 hour at room temperature.

Automatic Computer Analysis

For each condition, 20 pictures at 10× magnification (plate 1) or 30 pictures at 20× magnification (representing the whole well area) were automatically taken using ImageXpress®. All images were generated by ImageXpress® using the same acquisition parameters. From images, analyses were directly and automatically performed by Custom Module Editor®. The following read-outs were measured: Analysis of total number of TH neurons (TH positive neuron number), Analysis of the ROS into TH positive neurons, Analysis of caspase 3 positive TH neurons, and Analysis of total neurite network of TH positive neurons (in μm).

Statistical Analysis

All values are expressed as mean+/−SEM (standard error of the mean). Statistical analysis was performed by one-way ANOVA, followed by a Dunnett's or a PLSD Fisher's test. p<0.05 is considered significant.

Example 7. Compound Profiling in an α-Synuclein Aggregation Assay

Assay measuring α-synuclein expression and aggregation in differentiated neuronal ReNcell VM cells transduced with human α-synuclein-WT were used to assess the α-synuclein modulation characteristics of compounds. To this purpose, ReNcell VM cells in growth medium (containing EGF and bFGF) were seeded in 96-well laminin-coated plates.

Three (3) days post-seeding, on DO, the cells were refreshed with differentiation medium (devoid of EGF and bFGF, supplemented with cAMP and GDNF) and transduced with α-synuclein-encoding adenoviruses. On D1, after overnight transduction, the adenoviral medium was removed and test compound CRCs diluted in differentiation medium were added to the cells in biological duplicates (i.e. in wells located on separate assay plates processed on the same day). The assay includes a compound refreshment on D4. On each plate tested, up to six (6) vehicle control samples (0.1% DMSO) and up to six (6) positive control samples (10 μM KU 0063794) were included. Furthermore, each assay run includes an 8-point CRC of the reference compound KU 0063794. After six (6) days of compound treatment (on D7), the cells were fixed using 3.7% formaldehyde.

Assay readouts were aggregate-selective (MJFR-14) and α/β-synuclein (Syn205) immunoreactivity, quantified using high-content analysis with algorithms for Density×Area (D×A). Co-staining of cell nuclei with DAPI is performed to quantify cell number as a measure of potential toxicity. Synuclein immunoreactivity (D×A) was normalized for the number of nuclei (nuc) per imaged well (D×A/nuc). Compound performance was evaluated by efficacy (percentage inhibition (PIN) relative to positive control) and potency (pIC₅₀, when calculable) determination.

Assay quality was confirmed using the following pre-set criteria: Toxicity: ≤25% nuclei loss compared to average DMSO control, Coefficient of variation (CV): ≤20% CV for DMSO control, Assay window: ≥2.0 for Syn205, and Assay window: ≥1.5 for MJF-14.

Example 8. Effects of Compound 1206 in a Mouse Model of Polycystic Kidney Disease

Compound 1206 (10 mg/kg po, QD dosing for 14d, n=13/group) was assessed in a tamoxifen-induced polycystic kidney disease model (Ksp-TamCre×PkdlLox; Human Molecular Genetics, 2007, Vol. 16, No. 24, 3188-3196). A negative control group induced with tamoxifen (Vehicle) and a negative control group not induced with tamoxifen (No Tam) were included. A positive control group was dosed with everolimus. Mice were dosed orally on both PND 10, 11 with 25 mg/kg tamoxifen. Oral dosage of vehicle, compound 1206, and everolimus started from PND 14 onwards to PND 27. The readouts of this study were body weight, kidney weight, BUN levels and histopathology assessment including cyst index.

The fixated kidney half was processed for paraffin embedding and further pathological assessment after hematoxylin-eosin staining. One piece of each H-E stained kidney half was observed by a board certified pathologist, who read a cross section of the kidney. For each kidney one section was evaluated. From this section an overview photo was taken (2X) and used to calculate the cystic index. The cystic areas were identified by a color thresholding method using an image analysis system (Image software, public domain software, NIH, Bethesda, Md.). The threshold area was calculated within a defined ROI (region of interest) representing the total area analyzed. This area represents at least 70-80% of the entire kidney section. The cystic index (CI) is defined as the percentage of the area of cysts lumen (in pixels) over the total kidney area in the selected ROI (in pixels).

Exemplary results are shown in FIGS. 17A to 17C. FIG. 17A shows that, compared to the tamoxifen-induced vehicle control group, the 2 KW/BW ratio was significantly lower in the everolimus (positive control) group and in the compound 1206 group. FIG. 17B shows that the mice treated with compound 1206 had significantly lower urea levels (BUN) as compared with the mice in the tamoxifen-induced vehicle control group. In general, the mice in the no-tamoxifen induced control group (No Tam) had urea levels within the normal physiological range. FIG. 17C shows that the mice in the compound 1206 group had a significantly lower cystic index than the mice in the tamoxifen-induced vehicle control group. The same was true for the everolimus (positive control) group.
