Title: Small molecule autophagy inducers for the treatment of cancer and neurodegenerative diseases

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application No. 62/838,001, filed Apr. 24, 2019, which is incorporated herein by reference in its entirety. 
    
    
     FIELD 
     This disclosure relates to autophagy-stimulating compositions and methods of their use, particularly for treating cancer and neurodegenerative disease. 
     BACKGROUND 
     Triple negative breast cancer (TNBC) affects a significant portion of women in the United States, with a high frequency of recurrence, metastatic disease, and short survival times. Mortality rates are highest among African-American women and limited treatment options are available. The absence of hormone and Her2 receptors on TNBC precludes the use of targeted therapies that are available for other breast cancer subtypes, and cytotoxic chemotherapy such as paclitaxel and doxorubicin remains the mainstay of treatment for TNBC. 
     Glioblastoma multiforme (GBM) is one of the most aggressive primary brain tumors, with a poor prognosis despite maximal standard of care treatment. The overall survival rate for patients with this disease has not significantly increased, despite decades of research. Recurrence of GBM is common, and its management is often unclear and case-dependent. 
     Protein aggregation is the main cause of several human neurodegenerative diseases such as Alzheimer&#39;s disease (AD), Parkinson&#39;s disease (PD), Huntington&#39;s disease (HD), and amyotrophic lateral sclerosis (ALS). The aggregates usually consist of fibers containing misfolded protein with a β-sheet conformation, termed amyloid. There is partial but not perfect overlap among the cells in which abnormal proteins are deposited and the cells that degenerate. Protein aggregation is a highly complex process resulting in formation of a variety of aggregates with different structures and morphologies. Many of them are highly cytotoxic. The clearance of these misfolded proteins may represent a promising therapeutic strategy in these diseases.

     DETAILED DESCRIPTION 
     Autophagy is a conserved catabolic process that maintains homeostasis by regulating the energy balance of the cell. Depending on tumor type and environment, autophagy modulation plays an important role in tumor cell survival and inhibition pathways. Increasing evidence supports that chemical modulation of autophagy inhibition and activation holds a therapeutic potential and these studies have led to the initiation of multiple clinical trials combining chemotherapeutic agents and autophagy inhibitors and activators for various cancer types. Nonspecific autophagy inhibitors/activators have been widely used in a number of clinical trials, including GBM, as an adjuvant therapy with chemotherapeutic agents. However, lack of specificity of these compounds is associated with toxicity that diminishes efficacy. 
     Protein aggregation is associated with human neurodegenerative diseases (including AD, PD, HD, and ALS). The two main routes for intracellular protein degradation are the ubiquitin-proteasome and the autophagy-lysosome pathways. 
     The compound VMY-BC-1 is predicted to bind to ULK1, and is shown herein to stimulate apoptosis and autophagy pathways and increase phosphorylation of autophagy proteins in tumor cells. As disclosed herein, the autophagy activator VMY-BC-1 inhibited growth of triple-negative breast cancer cells and glioblastoma cells both in vitro and in vivo. In addition, VMY-BC-1 was shown to reduce poly-glutamine aggregates in  C. elegans  at low dose. These results suggest that the disclosed compositions can be useful in treating cancer and neurodegenerative diseases.

     In order to facilitate review of the various embodiments of the disclosure, the following explanations of specific terms are provided: 
     Aldehyde: —C(O)H. 
     Aliphatic: A hydrocarbon group having at least one carbon atom to 50 carbon atoms (C 1-50 ), such as one to 25 carbon atoms (C 1-25 ), or one to ten carbon atoms (C 1-10 ), and which includes alkanes (or alkyl), alkenes (or alkenyl), alkynes (or alkynyl), including cyclic versions thereof, and further including straight- and branched-chain arrangements, and all stereo and position isomers as well. 
     Alkenyl: An unsaturated monovalent hydrocarbon having at least two carbon atom to 50 carbon atoms (C 2-50 ), such as two to 25 carbon atoms (C 2-25 ), or two to ten carbon atoms (C 2-10 ), and at least one carbon-carbon double bond, wherein the unsaturated monovalent hydrocarbon can be derived from removing one hydrogen atom from one carbon atom of a parent alkene. An alkenyl group can be branched, straight-chain, cyclic (e.g., cycloalkenyl), cis, or trans (e.g., E or Z). 
     Alkyl: A saturated monovalent hydrocarbon having at least one carbon atom to 50 carbon atoms (C 1-50 ), such as one to 25 carbon atoms (C 1-25 ), or one to ten carbon atoms (C 1-10 ), wherein the saturated monovalent hydrocarbon can be derived from removing one hydrogen atom from one carbon atom of a parent compound (e.g., alkane). An alkyl group can be branched, straight-chain, or cyclic (e.g., cycloalkyl). 
     Alkynyl: An unsaturated monovalent hydrocarbon having at least two carbon atom to 50 carbon atoms (C 2-50 ), such as two to 25 carbon atoms (C 2-25 ), or two to ten carbon atoms (C 2-10 ), and at least one carbon-carbon triple bond, wherein the unsaturated monovalent hydrocarbon can be derived from removing one hydrogen atom from one carbon atom of a parent alkyne. An alkynyl group can be branched, straight-chain, or cyclic (e.g., cycloalkynyl). 
     Aromatic: A cyclic, conjugated group or moiety of, unless specified otherwise, from 5 to 15 ring atoms having a single ring (e.g., phenyl) or multiple condensed rings in which at least one ring is aromatic (e.g., naphthyl, indolyl, or pyrazolopyridinyl); that is, at least one ring, and optionally multiple condensed rings, have a continuous, delocalized TE-electron system. Typically, the number of out of plane π-electrons corresponds to the Hückel rule (4n+2). The point of attachment to the parent structure typically is through an aromatic portion of the condensed ring system. For example, 
     
       
         
         
             
             
         
       
     
     However, in certain examples, context or express disclosure may indicate that the point of attachment is through a non-aromatic portion of the condensed ring system. For example, 
     
       
         
         
             
             
         
       
     
     such as with a heterocyclic-aromatic group. An aromatic group or moiety may comprise only carbon atoms in the ring, such as in an aryl group or moiety, or it may comprise one or more ring carbon atoms and one or more ring heteroatoms comprising a lone pair of electrons (e.g., S, O, N, P, or Si), such as in a heteroaryl group or moiety. Aromatic groups may be substituted with one or more groups other than hydrogen, such as aliphatic, heteroaliphatic, haloaliphatic, haloheteroaliphatic, aromatic, or an organic functional group. 
     Aryl: An aromatic carbocyclic group comprising at least five carbon atoms to 15 carbon atoms (C 5 -C 15 ), such as five to ten carbon atoms (C 5 -C 10 ), having a single ring or multiple condensed rings, which condensed rings can or may not be aromatic provided that the point of attachment to a remaining position of the compounds disclosed herein is through an atom of the aromatic carbocyclic group. Aryl groups may be substituted with one or more groups other than hydrogen, such as aliphatic, heteroaliphatic, haloaliphatic, haloheteroaliphatic, aromatic, or an organic functional group. 
     Azepanyl: 
     
       
         
         
             
             
         
       
     
     Autophagy: A process by which cells degrade and recycle cellular components, including damaged or dysfunctional organelles, proteins, and cell membrane. The targeted cellular components are isolated in autophagosomes, which fuse with lysosomes where the contents are degraded and recycled. Autophagy is believed to play a role in pathologies such as cancer and neurodegenerative disorders. 
     Breast cancer: A malignant neoplasm that arises in or from breast tissue (such as a ductal carcinoma). Breast cancers are frequently classified as luminal A (ER positive and/or PR positive, ErbB2 negative, and low Ki67), luminal B (ER positive and/or PR positive and ErbB2 positive, or ErbB2 negative with high Ki67), basal-like or triple-negative (ER negative, PR negative, ErbB2 negative, cytokeratin 5/6 positive and/or HER1 positive), or ErbB2 positive (ER negative, PR negative, ErbB2 positive). However, breast cancers may be heterogeneous both between individuals and at the cellular level within a tumor, and may not always fit within the classification scheme. 
     “Triple negative breast cancer” (TNBC) is a subtype of breast cancer characterized by lack of expression of estrogen and progesterone receptors (ER/PR) and lack expression of (or lack overexpression of) human epidermal growth factor receptor-2 (referred to as HER2 or ErbB2) in the tumor cells. In some examples, TNBC is invasive ductal carcinoma or ductal carcinoma in situ. In other examples, TNBC is basal-like breast cancer. The pathological features of TNBC may include lymphocytic infiltrate, pushing borders, high mitotic rate (&gt;19/10 HPF), central necrosis, medullary features, and metaplastic elements (e.g., squamous cells and spindle cells). 
     Cancer: A malignant neoplasm that has undergone anaplasia with loss of differentiation, increased rate of growth, invasion of surrounding tissue, and is capable of metastasis. As used herein, cancer includes both solid tumors and hematological malignancies. Residual cancer is cancer that remains in a subject after any form of treatment is given to the subject to reduce or eradicate cancer. Metastatic cancer is a cancer at one or more sites in the body other than the original site of the cancer from which the metastatic cancer is derived. Local recurrence is a reoccurrence of the cancer at or near the same site as the original cancer, for example, in the same tissue as the original cancer.

     Glioblastoma: Also known as glioblastoma multiforme (GBM), which accounts for about 15% of brain tumors. GBM are aggressive tumors, with average survival of about 12-15 months following diagnosis. The pathological features of GBM include small areas of necrotizing tumor surrounded by anaplastic cells and the presence of hyperplastic blood vessels. GBM is difficult to treat, in part due to the limited ability of most drugs to cross the blood-brain barrier and contact the tumor.

     ULK1: unc-51 like autophagy activating kinase 1; also known as Unc51.1 or UNC51. ULK1 is a ubiquitously expressed serine/threonine protein kinase involved in autophagy. It is a 112-kDa protein that consists of an N-terminal kinase domain, a serine-proline rich region, and a C-terminal interacting domain (Zhang et al.,  J. Med. Chem.  61:6491-6500, 2018). ULK1 activity is negatively regulated by mammalian target of rapamycin complex 1 (mTORC1) and positively regulated by AMP-activated protein kinase (AMPK), depending on the phosphorylation sites in the serine-proline rich region (Kim et al.,  Nat. Cell Biol.  13:132-141, 2011). Stress signals are mediated through the C-terminal domain and autophagy is propagated through the ULK1-ATG13-FIP200 complex (Zhang et al.,  J. Med. Chem.  61:6491-65002018; He et al.,  J. Med. Chem.  61:4656-4687, 2017).

Description of suitable pharmaceutically acceptable salts can be found in  Handbook of Pharmaceutical Salts, Properties, Selection and Use , Wiley VCH (2002). 
     “Prodrug” refers to compounds that are transformed in vivo to yield a biologically active compound, particularly the parent compound, for example, by hydrolysis in the gut or enzymatic conversion. Any chemical compound recited in this specification may alternatively be administered as a prodrug thereof. Common examples of prodrug moieties include, but are not limited to, ester and amide forms of a compound having an active form bearing a carboxylic acid moiety. Examples of pharmaceutically acceptable esters of the disclosed compounds include, but are not limited to, esters of phosphate groups and carboxylic acids, such as aliphatic esters, particularly alkyl esters (for example C 1-6 alkyl esters). Other prodrug moieties include phosphate esters, such as —CH 2 —O—P(O)(OR′) 2  or a salt thereof, wherein R′ is H or C 1 -6alkyl. Acceptable esters also include cycloalkyl esters and arylalkyl esters such as, but not limited to benzyl. Examples of pharmaceutically acceptable amides of the disclosed compounds include, but are not limited to, primary amides, and secondary and tertiary alkyl amides (for example with between about one and about six carbons). Amides and esters of disclosed exemplary embodiments of compounds can be prepared. A thorough discussion of prodrugs is provided in T. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems,” Vol 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference for all purposes. 
     In some non-limiting examples, the disclosed compounds activate ULK1 and/or increase autophagy. For example, as disclosed in the Examples (below), VMY-BC-1 is a compound that increases ULK1 phosphorylation and autophagy. Methods of determining whether a compound activates ULK1 and/or increases autophagy include those described in the Examples. In one example, activation of ULK1 is determined by detecting an increase in phosphorylation of ULK1 (for example, by Western blot) compared to a resting state or a control. For example, activation of ULK1 by a compound can be determined by treating a cell expressing ULK1 with a compound of interest and detecting phosphorylation of ULK1 compared to an untreated cell or a cell treated with a control compound (such as vehicle). In other examples, an increase in autophagy is determined by detecting an increase in phosphorylation of ULK1, increased expression of LC3, and/or increase in cleaved PARP (for example by Western blotting). For example, an increase in autophagy can be determined by treating a cell with a compound of interest and detecting phosphorylation of ULK1, increased expression of LC3, and/or increased cleaved PARP compared to an untreated cell or a cell treated with a control compound (such as vehicle). In other examples, an increase in autophagy can be determined by treating a cell with a compound of interest and detecting expression and/or phosphorylation of p62, beclin-1, autophagy-related protein (ATG, e.g., ATG13 or ATG101), AMPK, and/or mTOR compared to an untreated cell or a cell treated with a control compound (such as vehicle).

     III. Methods of Treatment 
     Disclosed herein are methods of treating cancer or neurodegenerative disease. In some embodiments, the methods include administering an effective amount of a composition that increases autophagy to a subject with cancer or a neurodegenerative disease. 
     Disclosed are methods of treating triple-negative breast cancer, brain cancer (for example, glioblastoma multiforme) with compositions including VMY-BC-1 (Formula I). Also disclosed are methods of treating cancer with compositions including derivatives or analogs of VMY-BC-1. In some embodiments, the methods include administering an effective amount of a composition including the compound of Formula I to a subject with TNBC or brain cancer (such as GBM). In further embodiments, the methods include administering an effective amount of a composition including the compound of any one of Formulas II-IV to a subject with cancer. 
     In some examples, the subject being treated has cancer, such as a solid tumor or a hematological malignancy. Examples of solid tumors, include sarcomas (such as fibrosarcoma, myxosarcoma, liposarcoma, chondrosarcoma, osteosarcoma, soft tissue sarcoma, and other sarcomas), synovioma, mesothelioma, Ewing sarcoma, leiomyosarcoma, rhabdomyosarcoma, colon cancer, colorectal cancer, peritoneal cancer, esophageal cancer (such as esophageal squamous cell carcinoma), pancreatic cancer, breast cancer (including basal breast carcinoma, ductal carcinoma and lobular breast carcinoma), endometrial cancer, lung cancer (such as non-small cell lung cancer), ovarian cancer, prostate cancer, liver cancer (including hepatocellular carcinoma), gastric cancer, squamous cell carcinoma (including head and neck squamous cell carcinoma), basal cell carcinoma, adenocarcinoma, sweat gland carcinoma, medullary thyroid carcinoma, papillary thyroid carcinoma, pheochromocytoma, sebaceous gland carcinoma, papillary carcinoma, papillary adenocarcinoma, medullary carcinoma, bronchogenic carcinoma, hepatoma, bile duct carcinoma, choriocarcinoma, Wilms tumor, cervical cancer, fallopian tube cancer, testicular tumor, seminoma, bladder cancer (such as renal cell cancer), melanoma, and CNS tumors (such as a glioma, glioblastoma, astrocytoma, medulloblastoma, craniopharyrgioma, ependymoma, pinealoma, hemangioblastoma, acoustic neuroma, oligodendroglioma, meningioma, neuroblastoma and retinoblastoma). Solid tumors also include tumor metastases (for example, metastases to the lung, liver, brain, or bone). In some examples, the subject has hepatocellular carcinoma, neuroblastoma, breast cancer, gastric cancer, endometrial cancer, bladder cancer (such as renal cell carcinoma), lung cancer (such as non-small cell lung cancer), cervical cancer, medulloblastoma, esophageal cancer (such as esophageal squamous cell carcinoma), prostate cancer, seminoma, glioblastoma, osteosarcoma, astrocytoma, or soft tissue sarcoma. In some particular examples, the subject has triple-negative breast cancer or brain cancer, such as glioblastoma. 
     Examples of hematological malignancies include leukemias, including acute leukemias (such as 11q23-positive acute leukemia, acute lymphocytic leukemia (ALL), T-cell ALL, acute myelocytic leukemia, acute myelogenous leukemia (AML), and myeloblastic, promyelocytic, myelomonocytic, monocytic and erythroleukemia), chronic leukemias (such as chronic myelocytic (granulocytic) leukemia, chronic myelogenous leukemia, and chronic lymphocytic leukemia), lymphoblastic leukemia, polycythemia vera, lymphoma, diffuse large B cell lymphoma, Burkitt lymphoma, T cell lymphoma, follicular lymphoma, mantle cell lymphoma, Hodgkin disease, non-Hodgkin lymphoma, multiple myeloma, Waldenstrom macroglobulinemia, heavy chain disease, myelodysplastic syndrome, hairy cell leukemia, and myelodysplasia. 
     In some examples, the subject with cancer is treated with one or more additional therapies, such as surgery, radiation therapy, chemotherapy, and/or immunotherapy. A clinician can select appropriate treatments for the subject based on the type of cancer, the stage of cancer, response to prior therapies, the condition of the patient, and other factors. In one specific non-limiting example, the subject has TNBC and is treated with a compound of any one of Formulas I-IV and is also treated with surgery and/or chemotherapy (such as cisplatin or carboplatin). 
     Also disclosed are methods of treating a neurodegenerative disease. In some embodiments, an effective amount of a composition including the compound of any one of Formulas I-IV is administered to a subject with a neurodegenerative disease. Exemplary neurodegenerative diseases include Alzheimer&#39;s disease, Parkinson&#39;s disease, Huntington&#39;s disease, amyotrophic lateral sclerosis (ALS), tauopathies (such as progressive supranuclear palsy, corticobasal degeneration and frontotemporal dementia), spinocerebellar ataxias, spinal and bulbar muscular dystrophy, hereditary spastic paraplegias, Lafora disease, Charcot-Marie-Tooth disease, and AIDS dementia. In particular examples, the neurodegenerative disease is associated with presence of protein aggregation in the brain of the subject and treatment with one or more of the disclosed compositions decreases the presence or amount of protein aggregations in the brain. 
     The disclosed compounds can be formulated as pharmaceutical compositions for administration to a subject. In some examples, one or more of the provided compounds are combined with a pharmaceutically acceptable carrier or vehicle for administration to human or animal subjects. Examples of suitable pharmaceutically acceptable carriers, vehicles, or excipients include sterile aqueous or non-aqueous solutions, suspensions, and/or emulsions. Examples of non-aqueous solvents include propylene glycol, polyethylene glycol, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. Parenteral vehicles include sodium chloride solution, Ringer&#39;s dextrose, dextrose and sodium chloride, lactated Ringer&#39;s, or fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers (such as those based on Ringer&#39;s dextrose), and the like. Preservatives and other additives may also be present, such as surfactants, wetting or emulsifying agents (e.g., sorbitan monolaurate), buffers (e.g., sodium acetate), antimicrobials, anti-oxidants, chelating agents, inert gases, and the like.  Remington: The Science and Practice of Pharmacy , The University of the Sciences in Philadelphia, Editor, Lippincott, Williams, &amp; Wilkins, Philadelphia, Pa., 21 st  Edition (2005), describes compositions and formulations suitable for pharmaceutical delivery of one or more therapeutic compounds or molecules. 
     Pharmaceutical compositions for oral use can also be formulated, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsion hard or soft capsules, or syrups or elixirs. Such compositions may contain one or more agents selected from the group of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with suitable non-toxic pharmaceutically acceptable excipients including, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, such as corn starch, or alginic acid; binding agents, such as starch, gelatin or acacia, and lubricating agents, such as magnesium stearate, stearic acid or talc. The tablets can be uncoated, or they may be coated by known techniques in order to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. Pharmaceutical compositions for oral use can also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium such as peanut oil, liquid paraffin or olive oil. 
     The disclosed compounds can be administered by any means, such as by intravenous, intramuscular, subcutaneous, or intraperitoneal injection, or by oral, nasal, or anal administration. The disclosed compounds can also be administered topically, transdermally, or by local injection. In some embodiments, administration is oral (including buccal and/or sublingual administration), rectal, parenteral, aerosol, nasal, intravenous, intramuscular, subcutaneous, intradermal, or topical routes. To extend the time during which the compound is available to inhibit or treat a condition, the compound can be provided as an implant, an oily injection, a liposome, or as a particulate system. The particulate system can be a microparticle, a microcapsule, a microsphere, a nanoparticle, a nanocapsule, or similar particle. 
     In another embodiment, it may be desirable to administer the compounds or pharmaceutical compositions locally to the area in need of treatment. This may be achieved by, for example, local or regional infusion or perfusion, topical application, injection, catheter, suppository, or implant (e.g., implants formed from porous, non-porous, or gelatinous materials, including membranes, such as sialastic membranes or fibers), and the like. 
     In yet another embodiment, the compounds or pharmaceutical compositions can be delivered in a controlled release system. In one embodiment, a pump can be used (see, e.g., Langer  Science  249:1527-1533, 1990 ; Sefton Crit. Rev. Biomed. Eng.  14:201-240, 1987; Buchwald et al.,  Surgery  88:507-516, 1980; Saudek et al.,  N. Engl. J. Med.  321:574-579, 1989). In another embodiment, polymeric materials can be used (see, e.g., Ranger et al.,  Macromol. Sci. Rev. Macromol. Chem.  23:61-64, 1983; Levy et al.,  Science  228:190-192, 1985; During et al.,  Ann. Neurol.  25:351-356, 1989; and Howard et al.,  J. Neurosurg.  71:105-112, 1989). Other controlled release systems, such as those discussed in the review by Langer ( Science  249:1527-1533, 1990), can also be used. 
     Appropriate dosages for the disclosed compositions can be determined. The specific dose level and frequency of dosage for any particular subject may be varied and will depend upon a variety of factors, including the activity of the specific compound, the metabolic stability and length of action of that compound, the particular disease or disorder to be treated, the general health of the subject, the mode and time of administration, rate of excretion, and/or any drug combinations administered. Treatment can involve daily or multi-daily, weekly, bi-monthly, or monthly doses of compound(s) over a period of a few days or weeks to months, or even years. 
     The disclosed compounds can be conveniently presented in unit dosage form and prepared using conventional pharmaceutical techniques. Such techniques include the step of bringing into association the active ingredient and the pharmaceutical carrier(s) or excipient(s). In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers. The formulations may be included in unit-dose or multi-dose containers, for example, sealed ampoules and vials, and may be stored in a dried condition requiring only the addition of a sterile liquid carrier, for example, water or saline for injections, immediately prior to use. In certain embodiments, unit dosage formulations are those containing a dose or unit, or an appropriate fraction thereof, of the administered ingredient. 
     The amount of the compound that will be effective depends on the nature of the disorder or condition to be treated, as well as the stage of the disorder or condition. Effective amounts can be determined by in vitro studies, animal studies, and clinical techniques. The precise dose of the compounds to be included in the formulation will also depend on the route of administration, and should be decided according to the judgment of the health care practitioner and each subject&#39;s circumstances. An example of such a dosage range is 1 μg/kg to 200 mg/kg body weight (for example, about 5 μg/kg to 1 mg/kg, about 10 μg/kg to 5 mg/kg, about 100 μg/kg to 20 mg/kg, about 0.2 to 100 mg/kg, about 0.5 to 50 mg/kg, about 1 to 25 mg/kg, about 5 to 75 mg/kg, about 50 to 150 mg/kg, or about 100 to 200 mg/kg) in single or divided doses. For example, a suitable dose may be about 0.1 mg/kg, about 0.2 mg/kg, about 0.5 mg/kg, about 0.75 mg/kg, about 1 mg/kg, about 2 mg/kg, about 5 mg/kg, about 7.5 mg/kg, about 10 mg/kg, about 15 mg/kg, about 25 mg/kg, about 50 mg/kg, about 75 mg/kg, about 100 mg/kg, about 150 mg/kg, or about 200 mg/kg. 
     In other examples, the dosage range is 50-500 mg/m 2  (for example, about 50 to 100 mg/m 2 , about 75 to 150 mg/m 2 , about 125 to 200 mg/m 2 , about 175 to 250 mg/m 2 , about 225 to 300 mg/m 2 , about 275 to 350 mg/m 2 , about 325 to 400 mg/m 2 , about 375 to 450 mg/m 2 , or about 425 to 500 mg/m 2 ) in single or divided doses. For example, a suitable dose may be about 50 mg/m 2 , about 75 mg/m 2 , about 100 mg/m 2 , about 125 mg/m 2 , about 150 mg/m 2 , about 175 mg/m 2 , about 200 mg/m 2 , about 225 mg/m 2 , about 250 mg/m 2 , about 275 mg/m 2 , about 300 mg/m 2 , about 325 mg/m 2 , about 350 mg/m 2 , about 375 mg/m 2 , about 400 mg/m 2 , about 425 mg/m 2 , about 450 mg/m 2 , about 475 mg/m 2 , or about 500 mg/m 2 . In one non-limiting example, the dose is about 200 to 300 mg/m 2 . However, other higher or lower dosages also could be used, as can be determined by in vitro and/or in vivo testing.

     Example 2 
     Effect of VMY-BC-1 on Triple Negative Breast Cancer Cell Lines A trans-stilbene boronic acid analog, VMY-BC-1, was tested against a TNBC cell line. VMY-BC-1 significantly inhibited growth of MDA-MB-231 TNBC cells ( FIG. 2A ). VMY-1BC-1 also significantly inhibited TNBC cell invasion in a time-dependent manner ( FIG. 2B ). 
     Example 3 
     Identifying Molecular Target of VMY-BC-1 
     A global quantitative proteomics approach using multiplexed tandem mass tagged (TMT) isotope labeling technology and shotgun mass spectrometry (Hung et al.,  Anal. Chem.  84:161-170, 2012) ( FIG. 3 ) was used to quantitate approximately 5,400 proteins. MDA-MB-231 cells were treated with vehicle control (DMSO) or 10 μM VMY-BC-1 for 4 time points. Equal amounts of protein from cell lysates were trypsin digested (Step 1) and labelled with TMT 10-plex reagent (Step 2). Labelled peptide samples were analyzed by shotgun mass spectrometry (Step 3) which resulted in quantification of ˜5,400 proteins. 
     Proteins that were differentially expressed in the TNBC cell line MDA-MB-231 treated with VMY-BC-1 compared to vehicle control were subjected to Ingenuity Pathway Analysis (IPA) to identify significantly altered pathways. Treatment with VMY-BC-1 led to activation of apoptosis, autophagy, and DNA damage pathways, and inhibition of mTOR1, PI3K, and AKT pathways (Z score=0.156, p value=1.97E-10) ( FIG. 4 ). 
     To further elucidate targets that activate the above signaling mechanisms, thermal proteome profiling (TPP) was used to identify binding proteins (Franken et al.,  Nat. Protoc.  10:1567-1593, 2015; Miettinen et al.,  EMBO J.  37:e98359, 2018) ( FIG. 5A ). TPP enables an unbiased assessment of the proteins covalently bound to VMY-BC-1 on a proteome-wide scale. Cell lysates were made from MDA-MB-1 cells treated with vehicle or 10 μM VMY-BC-1 for 24 hours. Lysates were heated at different temperatures for 3 minutes in a thermal cycler. Equal amounts of protein were digested, labeled with TMT 10-plex and analyzed by mass spectrometry. The fold-changes in protein abundances were computed relative to the lowest temperature in the temperature set. After a normalization, melting curves were fitted to the fold-changes of each individual protein. The thermal stability of proteins affected by VMY-BC-1 treatment was calculated using the differences between melting points from control for each protein. From the 5,634 proteins screened, 10 target proteins were identified that bound VMY-BC-1: LIMK1, ATM, CDLK5, ULK1, WNK1, PP2C, AK1, IKBKAP, Q53E18, and HDAC1 ( FIG. 5B ). The limited fraction of bound protein (0.0017%) suggests a highly selective nature of VMY-BC-1. 
     To identify the functional target of VMY-BC-1, preliminary cell viability assays were carried out using siRNA to knock down each of the 10 identified binding proteins. Knock down of both ATM and ULK1 abrogated the functional activity of VMY-BC-1. Considering that that low ULK1 expression is associated with TNBC disease progression (Tang et al.,  Breast Cancer Res. Treat.  134:549-560, 2012) and autophagy controls the level of various DNA repair and checkpoint proteins in the DNA damage response pathway (Czarny et al.,  Int. J. Mol. Sci.  16:2641-2662, 2015; Gomes et al.,  Int. J. Mol. Sci.  18:2351, 2017), ULK1 activity in response to VMY-BC-1 was investigated. Protein extracts were made from MDA-MB-231 cells treated with vehicle control, VMY-BC-1 (10 μM), and Rapamycin (200 nM) at different time points. Western blots of ULK1 and late stage autophagic proteins LC3-I and LC3-II, from VMY-treated TNBC cells, showed increasing amounts of autophagy proteins over time as well as increased phosphorylation of ULK1 and LC3 A/B ( FIG. 6 ). The western blot results also suggested that there was cross talk between the apoptosis and autophagy pathways as observed in the Ingenuity Pathway analysis ( FIG. 4 ). 
     Additionally, an in silico docking model suggests VMY-BC-1 occupies the same binding pocket in the ULK1 agonist site as the ULK1 activator LYN 1604 ( FIGS. 7A-7C ). Biochemical validation of ULK1 phosphorylation was consistent with data from TMT quantitative proteomics and thermal profiling analysis of pathways affected by VMY-BC-1, and the in silico data supports the hypothesis that VMY-BC-1 activates ULK1 by direct binding and activates autophagy-induced cell death in TNBC.

     Pharmacokinetics Analysis of VMY-BC-1 
     The parent compound of VMY, resveratrol (RSV), is limited in its utility as a therapeutic agent because of unfavorable pharmacokinetic (PK) properties such as poor bioavailability and rapid and extensive metabolism and excretion (Gambini et al.,  Oxid. Med. Cell Longev.  2015:837042, 2015; Ko et al.,  Int. J. Mol. Sci.  18:2589, 2017). Moreover, PK studies of RSV in humans conclude that even high concentration of RSV might be insufficient to achieve in vivo concentrations required for the systemic prevention of cancer. Therefore, in vitro ADME assays were carried out to assess VMY-BC-1 and to identify properties for further optimization. 
     The ADME results are shown in Table 3. In contrast to resveratrol, VMY-BC-1 was stable in simulated gastric and intestinal fluids, indicating that it may not undergo degradation under the intestinal pH conditions. VMY-BC-1 showed moderate to high intrinsic clearance (43 μL/min/mg of protein) in human liver microsomes (40% remaining at the end of 30 min incubation). VMY-BC-1 did not inhibit major CYP isozymes 2C9, 2C19, 2D6 and 3A with IC 50  (the concentration yielding 50% growth inhibition) values in the range of 70-100 μM in the pooled human liver microsomes. VMY-BC-1 weakly inhibited the CYP1A2 isozyme with a IC 50  value of 5 μM. VMY-BC-1 showed high permeability in the in vitro Caco-2 cell model, indicating that it may show rapid absorption following oral administration under linear pharmacokinetic conditions. VMY-BC-1 showed moderate plasma protein binding in CD1 mouse plasma.

     In vivo ADME characteristics were determined in male CD1 mice following VMY-BC-1 administration at 1 mg/kg intravenously and 25 mg/kg and 100 mg/kg orally ( FIG. 8 ). With intravenous administration, VMY-BC-1 showed mono-exponential decay with moderate plasma clearance (50% of hepatic blood flow), with a high volume of distribution (2.4 L/Kg) and an elimination half-life of approximately 1 hour. VMY-BC-1 displayed rapid oral absorption with a time to maximum concentration (Tmax) of 1.0-2.0 hour, and a mean maximum concentration (Cmax) of 3059 ng/mL. Oral suspension bioavailability F (%) was over 100% at 25 mg/kg, indicating elimination was saturated. A 4-fold increase in oral dose (25 to 100 mg/kg) resulted in approximately 5-fold increase in Cmax and 7-fold increase in plasma exposures. Sustained oral absorption following the 100 mg/kg oral administration indicated solubility was not limited oral absorption. When compared to reported PK parameters of resveratrol, VMY-BC-1 had improved PK parameters.

     Efficacy of VMY-BC-1 in Mouse Breast Cancer Xenograft Model 
     To evaluate the anti-tumor efficacy of VMY-BC-1 in vivo, MDA-MB-231 tumor xenografts were established in the flanks of athymic nude mice. 5×10 6  MDA-MB-231 TNBC cells in 1×HBSS with 1:1 Matrigel® were implanted subcutaneously in the flank of 5-6 week old female athymic nude mice (CrTac:Ncr-Foxn1 nu ; Taconic Biosciences, India). Mice (n=8) were treated with vehicle (2% (v/v) Tween® 80+98% (v/v) of 0.5% (w/v) hydroxypropyl methylcellulose (HPMC) in water) or VMY-BC-1 75 mg/kg PO daily for 14 days. The dose volume was 10 mL/kg. Tumor volume, tumor growth inhibition (TGI), body weight, and clinical signs were monitored. Tumor growth was measured twice weekly using a digital Vernier caliper. Tumor volume was calculated as [length×width 2 ]/2. TGI was calculated as: 
       % TGI={(TV Control Final −TV Control Initial )−(TV Treated Final −TV Treated Initial )}×100
 
     Tumor volume doubling time (TVDT) was calculated as: 
       TVDT=(TV Control Final −TV Control Initial )
 
     At the end of the study, brain and plasma samples were collected for drug concentration. Tumor tissues were collected for immunohistochemistry, Western blot, and bioanalysis. Statistical analysis of tumor growth in the control and treated groups was performed by Student&#39;s T test using GraphPad Prism (Ver. 5.03). 
     VMY-BC-1 significantly inhibited tumor growth by approximately 30% without any apparent change in body weight ( FIGS. 9A and 9B ). Analysis of tumor tissue demonstrated higher VMY-BC-1 drug levels in tumor than in plasma ( FIGS. 10A and 10B ), a 50% reduction in the Ki67 proliferation marker compared to the control treatment ( FIG. 11 ), and a significant increase in apoptosis as measured by TUNEL staining ( FIG. 12 ). The impact of VMY-BC-1 on autophagy proteins in tumor tissue was also investigated. Phospho-ULK1 and LC3 protein expression was upregulated in tumors treated with VMY-BC-1 compared to control ( FIG. 13 ). Finally, as shown in Table 4 and  FIGS. 10A and 10B , VMY-BC-1 had 3-fold higher drug concentration (C max ) in tumors than in plasma.

     Effect of VMY-BC-1 on Glioblastoma Cell Lines 
     The effect of VMY-BC-1 was tested on a panel of GBM cell lines. As shown in Table 5, VMY-BC-1 inhibited growth of established glioma cell lines and patient-derived GBM cell lines compared to normal cell lines. VMY-BC-1 also was more effective at inhibiting cell growth compared to resveratrol. Cells were cultured with VMY-BC-1 or resveratrol for 72 hours and cell viability was assessed using Alamar blue. 50 mM DMSO stocks of both VMY-BC-1 and Resveratrol were used, diluted into cell line media for dose response studies. In this study 100 μM was the highest drug concentration used, with 3-fold dilution for a 10 dose response curve.

     The effect of VMY-BC-1 on autophagy-related proteins in U87 cells was tested. Protein extracts were made from cells treated with vehicle control, VMY-BC-1 (10 μM), or rapamycin (200 nM) for 12-48 hours. Western blots of ULK1 and late stage autophagic proteins LC3-I and LC3-II showed increasing amounts of autophagy proteins over time as well as increased phosphorylation of ULK1 and LC3 A/B ( FIG. 14 ). 
     In addition, the effect of VMY-BC-1 on cell cycle pathways in U251 cells was assessed by flow cytometry ( FIG. 15 ). Cells were treated with 5 μM and 10 μM VMY-BC-1 for 24 hours. Cells were trypsinized, centrifuged, and cell pellets were collected. Pellets were resuspended in 1 ml of BS containing 1 mg/ml RNase and 50 mg/ml propidium iodide, incubated in the dark for 30 minutes at room temperature, and analyzed using a FACSort™ Flow Cytometer. The cell cycle distribution was evaluated on DNA plots using the flowzow software.

     Efficacy of VMY-BC-1 in Mouse Glioblastoma Xenograft Model 
     To evaluate the anti-tumor efficacy of VMY-BC-1 in vivo, GBM tumor xenografts were established in the flanks of SCID mice. 5×10 6  U87 MG (ATCC HTB-14™) cells in 1×HBSS with 1:1 Matrigel® were implanted subcutaneously in the flank of 5-6 week old female SCID mice (C.B-lgh-1b/GbmsTac-Prkdc scid -Lyst bg  N7; Taconic Biosciences, India). Mice (n=8) were treated with vehicle (2% (v/v) Tween® 80+98% (v/v) of 0.5% (w/v) hydroxypropyl methylcellulose (HPMC) in water) or VMY-BC-1 75 mg/kg PO daily for 14 days. The dose volume was 10 mL/kg. Tumor volume, tumor growth inhibition (TGI), body weight, and clinical signs were monitored as described in Example 5. 
     Once daily oral administration of VMY-BC-1 at 75 mg/kg resulted in 32% tumor growth inhibition at the end of 2 weeks ( FIG. 17A ). No treatment-related adverse effects were observed with respect to body weight ( FIG. 17B ) and clinical signs. Analysis of tumor tissue demonstrated higher VMY-BC-1 drug levels in tumor than in plasma ( FIGS. 18A-18C ). In addition, tumor tissue had a 51% reduction in the Ki67 proliferation marker compared to the control treatment ( FIG. 19 ), and a significant increase in apoptosis as measured by TUNEL staining ( FIG. 20 ).

     Efficacy of VMY-BC-1 in  C. elegans  Huntington&#39;s Disease Model 
     Synchronized populations of wild-type L1  C. elegans  hatched overnight were transferred to agar plates followed by VMY-BC-1 was added freshly from a 5 mM stock to the NGM media. Water was used as control. The L4 population of worms was randomly split to control or treatment groups in a density of about 20-30 worms per 6 cm plate dish. 
     The first day of adulthood was considered day one. In all the experiments with late-onset administration of VMY-BC-1, synchronized L4 animals were moved to the media supplemented with 5′-fluorodeoxyuridine (FUDR, Cayman chemicals) at a final concentration of 1 μM for 2 days to prevent reproduction, then were moved to FUDR-free NGM plates until the final treatments at day 10. The animals that crawled off the plate, ruptured, or died from internal hatching were censored. Worms were transferred to fresh plates every day after reaching adulthood, and every 2 days after reaching 10 days of age. Prodding test was used to count the number of dead worms. Survival curve was plotted using Prism 7 and the significance of the curves calculated by Log-rank (Mantel-Cox) test. 
     Synchronized populations of polyQ-expressing  C. elegans  were grown for 72 hours on media containing 1 μM VMY-BC-1. PolyQ aggegrative vacuoles were detected using confocal microscopy. PolyQ aggregations were decreased compared to vehicle (DMSO) ( FIG. 21A ). Synchronized populations of wild-type worms were grown on media containing VMY-BC-1 from 0.1 to 10 μM. From the results, a dose-dependent lifespan extension was observed ( FIG. 21B ). Maximal median lifespan extension (˜25%) was observed in animals treated with 1 μM VMY-BC-1.

     Example 16 
     Pharmacokinetics of BC-4 and BC-5 
     Pharmacokinetics of BC-4 and BC-5 were compared to BC-1. Pharmacokinetics were assessed in Balb/c mice administered a single oral dose of 5 mg/kg of the indicated compound (Tables 11 and 12). Both BC-4 and BC—S had higher concentrations in plasma than brain.
