GOVERNMENT SUPPORT INFORMATION This invention was made with government support under Grant Nos. R01 CA242003 and R01 CA241191 awarded by the National Institutes of Health. The government has certain rights in the invention. BACKGROUND The B-cell lymphoma 2 (Bcl-2) protein family, consisting of pro- and anti-apoptotic members, plays a critical role in determining cell fate through regulation of the intrinsic apoptosis pathway. The anti-apoptotic Bcl-2 family proteins, such as Bcl-2, Bcl-xL, Bcl-w, and Mcl-1, are upregulated in many cancers and associated with tumor initiation, progression, and resistance to chemo- and targeted therapies. Thus, these anti-apoptotic Bcl-2 proteins are attractive targets for the development of novel anti-cancer agents (Lessene et al., Nat Rev Drug Discov 7: 989-1000, 2008; Vogler et al., Cell Death Differ 2009;16: 360-367; Delbridge et al., Nat Rev Cancer 16: 99-109, 2016). Numerous Bcl-2 small molecule inhibitors have been reported (Bajwa et al., Expert Opin Ther Patents 22:37-55, 2012; Vogler, Adv Med.1-14, 2014; Ashkenazi et al., 16: 273-284, 2017). The following are some of the Bcl-2 small molecule inhibitors that have been investigated at various stages of drug development: ABT-737 (US20070072860), navitoclax (ABT-263, W02009155386), venetoclax (ABT-199, W02010138588), obatoclax (GX 15-070, W02004106328), (-)-gossypol (AT-101, W02002097053), sabutoclax (BI-97C1, W02010120943), TW-37 (W02006023778), BM-1252 (APG-1252), and A-1155463 (VV02010080503). Venetoclax, a selective Bcl-2 inhibitor, was approved by the FDA in 2016 for the treatment of chronic lymphocytic leukemia (CLL) with 17-p deletion. Venetoclax was designed to have high selectivity for Bcl-2 over Bcl-xL to avoid the on-target platelet toxicity (Souers et al., Nat Med 19: 202-208, 2013). Platelets depend on Bcl-xL to maintain their viability, therefore dose-limiting thrombocytopenia has been observed in animals and/or humans treated with ABT- 737 (Schoenwaelder et al., Blood 118: 1663-1674, 2011), ABT-263 (Tse et al., Cancer Res 68: 3421-3428, 2008; Roberts et al., Bri J Haematol 170: 669-678, 2015), BM-1197 (Bai et al., PLoS ONE 9:e99404, 2014), or A-1155463 (Tao et al., ACS Med Chem Lett 5:1088-1093,2014), due to their inhibition of Bcl-xL. However, many CLL patients are resistant to venetoclax (Roberts et al., N Engl J Med 374: 311-322, 2016) and upregulation of Bcl-xL by microenvironmental survival signals has been identified as the major component accountable for the resistance, consistent with the high efficacy of Bcl-2/Bcl-xL dual inhibitor ABT-263 in killing venetoclax resistant CLL cells (Oppermann et al., Blood 128: 934-947, 2016). In addition, Bcl-xL is generally more frequently overexpressed than Bcl-2 in solid tumors. Importantly, promising results have been documented from preclinical and clinical studies of ABT-263, as a single-agent or in combination with other antitumor agents, against several solid and hematologic malignancies (Delbridge et al., Nat Rev Cancer 16: 99-109, 2016). Therefore, it is highly desirable to develop a strategy that can retain the antitumor versatility and efficacy of the Bcl- xL/Bcl-2 dual inhibitors, while sparing their on-target platelet toxicity. Thus, there is a need to develop compounds that can retain the antitumor versatility and efficacy of the Bcl-xL/Bcl-2 dual inhibitors, while avoiding their on-target platelet toxicity. 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: In certain embodiments, the compounds include a Bcl-xL and/or Bcl-2 binding moiety cereblon (CRBN) binding moiety ( linker (e.g., –L ₃ –L ₂ –L ₁ –) connecting the Bcl- xL and/or Bcl-2 binding moiety and the CRBN binding moiety. Compared to known Bcl-xL and/or Bcl-2 inhibitors (e.g., ABT-263: , the compounds and pharmaceutical compositions provided herein may have unexpected advantages (e.g., increased potency and/or efficacy in inhibiting the activity and/or production of Bcl-xL and/or Bcl-2, increased bioavailability, reduced toxicity, increased safety, increased therapeutic window, reduced resistance, and/or increased subject compliance). In certain embodiments, the linker is shorter and/or more rigid than known linkers. The compounds may promote the degradation of the anti-apoptotic Bcl-2 family of proteins. The compounds may also promote the degradation of the anti-apoptotic Bcl-xL family of proteins. The compounds may be Bcl-xL/Bcl-2 dual inhibitors. The compounds may connect a Bcl-2 or Bcl-xL small molecule inhibitor or ligand to an E3 ligase binding moiety, such as CRBN. In humans, CRBN is a protein encoded by the CRBN gene (Ensembl: ENSG00000113851). In certain embodiments, CRBN forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A), and regulator of cullins 1 (ROC1). The compounds may actively recruit anti-apoptotic Bcl-2 family of proteins to E3 ligase, resulting in their degradation by ubiquitin proteasome system. Platelets depend on Bcl-xL protein for survival. Thus, inhibition of Bcl-xL protein in platelets causes thrombocytopenia which limits the use of Bcl-xL inhibitors as cancer therapeutic agents. Given the well-documented importance of Bcl-xL in solid tumors and its contribution to drug resistance, strategies devised to minimize the on-target platelet toxicity associated with the inhibition of Bcl-xL could boost the therapeutic applications of drugs like ABT-263, a dual Bcl- 2/Bcl-xL inhibitor, in cancer. The compounds of the present disclosure were designed to recruit CRBN E3 ligase, which is minimally expressed in platelets for the targeted degradation of Bcl- xL Thus, the compounds provided herein may reduce platelet toxicity compared with their corresponding Bcl-2/Bcl-xL inhibitors. Accordingly, the present disclosure provides compounds, pharmaceutical compositions, kits, and methods for at least selectively degrading anti-apoptotic Bcl-2 family of proteins.

Further salts include ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. The term “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 lower 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, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this disclosure 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 known 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.

Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. The term “solvate” refers to forms of the compound, or a salt thereof, 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. In some embodiments, the compounds provided herein are prepared, e.g., in crystalline form. In some embodiments, the compounds provided herein are prepared, e.g., in crystalline form, and are 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 isolatable solvates. Representative solvates include hydrates, ethanolates, and methanolates. The term “hydrate” refers to a compound, or a salt thereof, that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound, or a salt thereof, is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, in some embodiments, a hydrate of a compound, or a salt thereof, is represented, for example, by the general formula R⋅x H2O, wherein R is the compound, or a salt thereof, and x is a number greater than 0. A given compound, or a salt thereof, may form more than one type of hydrate, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R⋅0.5 H ₂ O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R⋅2 H2O) and hexahydrates (R⋅6 H2O)). The term “tautomers” or “tautomeric” refers to two or more interconvertible compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa). The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Tautomerizations (i.e., the reaction providing a tautomeric pair) may catalyzed by acid or base. Exemplary tautomerizations include keto-to-enol, amide-to-imide, lactam-to-lactim, enamine-to- imine, and enamine-to-(a different enamine) tautomerizations. 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. In some embodiments, an enantiomer is 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 “co-crystal” refers to a crystalline structure comprising at least two different components (e.g., a compound disclosed herein and an acid), wherein each of the components is independently an atom, ion, or molecule. In certain embodiments, none of the components is a solvent. In certain embodiments, at least one of the components is a solvent. A co-crystal of a compound disclosed herein and an acid is different from a salt formed from a compound disclosed herein and the acid. In the salt, a compound disclosed herein is complexed with the acid in a way that proton transfer (e.g., a complete proton transfer) from the acid to a compound disclosed herein easily occurs at room temperature. In the co-crystal, however, a compound disclosed herein is complexed with the acid in a way that proton transfer from the acid to a compound disclosed herein does not easily occur at room temperature. In certain embodiments, in the co-crystal, there is no proton transfer from the acid to a compound disclosed herein. In certain embodiments, in the co-crystal, there is partial proton transfer from the acid to a compound disclosed herein. In some embodiments, co-crystals are useful to improve the properties (e.g., solubility, stability, and ease of formulation) of a compound disclosed herein. The term “polymorph” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof). 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. In some embodiments, various polymorphs of a compound (or a salt, hydrate, or solvate thereof) are prepared by crystallization under different conditions. The term “prodrugs” refers to compounds that have cleavable groups and become by solvolysis or under physiological conditions the compounds described herein, which are pharmaceutically active in vivo. Such examples include, but are not limited to, choline ester derivatives and the like, N-alkylmorpholine esters and the like. Other derivatives of the compounds described herein have activity in both their acid and acid derivative forms, but in the acid sensitive form often offer 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 described herein are particular prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkylesters. In some embodiments, C ₁ -C ₈ alkyl, C2-C8 alkenyl, C2-C8 alkynyl, aryl, C7-C12 substituted aryl, and C7-C12 arylalkyl esters of the compounds described herein are preferred. The terms “composition” and “formulation” are used interchangeably. A “subject” to which administration is contemplated refers to a human (i.e., male or female of any age group, e.g., pediatric subject (e.g., infant, child, or adolescent) or adult subject (e.g., young adult, middle-aged adult, or senior adult)) or non-human animal. In certain embodiments, the non-human animal is a mammal (e.g., primate (e.g., cynomolgus monkey or rhesus monkey), commercially relevant mammal (e.g., cattle, pig, horse, sheep, goat, cat, or dog), or bird (e.g., commercially relevant bird, such as chicken, duck, goose, or turkey)). In certain embodiments, the non-human animal is a fish, reptile, or amphibian. In some embodiments, the non-human animal is a male or female at any stage of development. In some embodiments, the non-human animal is a transgenic animal or genetically engineered animal. The term “patient” refers to a human subject in need of treatment of a disease. The term “tissue” refers to any biological tissue of a subject (including a group of cells, a body part, or an organ) or a part thereof, including blood and/or lymph vessels. In some embodiments, “tissue” is the object to which a compound, particle, and/or composition of the disclosure is delivered. In some embodiments, a tissue is an abnormal or unhealthy tissue, which may need to be treated. A tissue may also be a normal or healthy tissue that is under a higher than normal risk of becoming abnormal or unhealthy, which may need to be prevented. 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 term “administer,” “administering,” or “administration” refers to implanting, absorbing, ingesting, injecting, inhaling, or otherwise introducing a compound provided herein, a compound useful in a provided method, or a pharmaceutical composition provided herein, in or on a subject. The terms “condition,” “disease,” and “disorder” are used interchangeably. The terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease described herein. In some embodiments, treatment is administered after one or more signs or symptoms of the disease have developed or have been observed. In other embodiments, treatment is administered in the absence of signs or symptoms of the disease. For example, in some embodiments, treatment is administered to a susceptible subject prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of exposure to a pathogen). 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. An “effective amount” of a compound described herein refers to an amount sufficient to elicit the desired biological response. An effective amount of a compound described herein may vary depending on such factors as the desired biological endpoint, severity of side effects, disease, or disorder, the identity, pharmacokinetics, and pharmacodynamics of the particular compound, the condition being treated, the mode, route, and desired or required frequency of administration, the species, age and health or general condition of the subject. In certain embodiments, an effective amount is a therapeutically effective amount. In certain embodiments, an effective amount is a prophylactic treatment. In certain embodiments, an effective amount is the amount of a compound described herein in a single dose. In certain embodiments, an effective amount is the combined amounts of a compound described herein in multiple doses. In certain embodiments, the desired dosage is delivered three times a day, two times a day, once a day, every other day, every third day, every week, every two weeks, every three weeks, or every four weeks. In certain embodiments, the desired dosage is delivered using multiple administrations (e.g., two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, or more administrations). A “therapeutically effective amount” of a compound described herein 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, signs, or causes of the condition, and/or enhances the therapeutic efficacy of another therapeutic agent. In certain embodiments, a therapeutically effective amount is an amount sufficient for treating a disease. A “prophylactically effective amount” of a compound described herein 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. In certain embodiments, a prophylactically effective amount is an amount sufficient for preventing a disease. The term “inhibit” or “inhibition”, for example, in the context of a Bcl-xL or Bcl-2, refers to a reduction in activity or production. In some embodiments, the term refers to a reduction of the level of activity and/or production, e.g., Bcl-xL or Bcl-2 activity and/or production, to a level that is statistically significantly lower than an initial level, which may, for example, be a baseline level of activity and/or production. In some embodiments, the term refers to a reduction of the level of activity and/or production, e.g., Bcl-xL or Bcl-2 activity and/or production, to a level that is less than 75%, less than 50%, less than 40%, less than 30%, less than 25%, less than 20%, less than 10%, less than 9%, less than 8%, less than 7%, less than 6%, less than 5%, less than 4%, less than 3%, less than 2%, less than 1%, less than 0.5%, less than 0.1%, less than 0.01%, less than 0.001%, or less than 0.0001% of an initial level, which may, for example, be a baseline level of activity and/or production. The term “Bcl-2 family” refers to a family consists of a number of evolutionarily- conserved proteins that share Bcl-2 homology (BH) domains. The Bcl-2 family may be able to regulate apoptosis at the mitochondrion. The Bcl-2 family may promote or inhibit apoptosis, or control apoptosis by governing mitochondrial outer membrane permeabilization (MOMP), which is a key step in the intrinsic pathway of apoptosis. In certain embodiments, the Bcl-2 family is a human Bcl-2 family. The term “Bcl-2” refers to a protein of the Bcl-2 family and, when in humans, is encoded by the BCL2 gene. The term “Bcl-xL” refers to a protein of the Bcl-2 family and, when in humans, is encoded by the BCL2-like 1 gene. 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.

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.

An ocular inflammatory disease includes post-surgical inflammation. 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.

The term “neurological disease” refers to any disease of the nervous system, including diseases that involve the central nervous system (brain, brainstem and cerebellum), the peripheral nervous system (including cranial nerves), and the autonomic nervous system (parts of which are located in both central and peripheral nervous system). Neurodegenerative diseases refer to a type of neurological disease marked by the loss of nerve cells, including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, tauopathies (including frontotemporal dementia), and Huntington’s disease.

In some embodiments, a particular pain can dominate. In other embodiments, the painful condition comprises two or more types of pains without one dominating. A skilled clinician can determine the dosage to achieve a therapeutically effective amount for a particular subject based on the painful condition. The term “metabolic disease” refers to any disorder that involves an alteration in the normal metabolism of carbohydrates, lipids, proteins, nucleic acids, or a combination thereof. A metabolic disorder is associated with either a deficiency or excess in a metabolic pathway resulting in an imbalance in metabolism of nucleic acids, proteins, lipids, and/or carbohydrates. Factors affecting metabolism include the endocrine (hormonal) control system (e.g., the insulin pathway, the enteroendocrine hormones including GLP-1, PYY or the like), the neural control system (e.g., GLP-1 in the brain), or the like. Examples of metabolic disorders include diabetes (e.g., Type I diabetes, Type II diabetes, gestational diabetes), hyperglycemia, hyperinsulinemia, insulin resistance, and obesity. The term “psychiatric disorder” refers to a condition or disorder relating to the functioning of the brain and the cognitive processes or behavior. Psychiatric disorders may be further classified based on the type of neurological disturbance affecting the mental faculties. Psychiatric disorders are expressed primarily in abnormalities of thought, feeling, emotion, and/or behavior producing either distress or impairment of function (for example, impairment of mental function such with dementia or senility). The term “psychiatric disorder” is, accordingly, sometimes used interchangeably with the term “mental disorder” or the term “mental illness”. A psychiatric disorder is often characterized by a psychological or behavioral pattern that occurs in an individual and is thought to cause distress or disability that is not expected as part of normal development or culture. Definitions, assessments, and classifications of mental disorders can vary, but guideline criteria listed in the International Classification of Diseases and Related Health Problems (ICD, published by the World Health Organization, WHO), or the Diagnostic and Statistical Manual of Mental Disorders (DSM, published by the American Psychiatric Association, APA) and other manuals are widely accepted by mental health professionals. Individuals may be evaluated for various psychiatric disorders using criteria set forth in these and other publications accepted by medical practitioners in the field and the manifestation and severity of a psychiatric disorder may be determined in an individual using these publications. Categories of diagnoses in these schemes may include dissociative disorders, mood disorders, anxiety disorders, psychotic disorders, eating disorders, developmental disorders, personality disorders, and other categories. There are different categories of mental disorder, and many different facets of human behavior and personality that can become disordered. One group of psychiatric disorders includes disorders of thinking and cognition, such as schizophrenia and delirium. A second group of psychiatric disorders includes disorders of mood, such as affective disorders and anxiety. A third group of psychiatric disorders includes disorders of social behavior, such as character defects and personality disorders. And a fourth group of psychiatric disorders includes disorders of learning, memory, and intelligence, such as mental retardation and dementia. Accordingly, psychiatric disorders encompass schizophrenia, delirium, attention deficit disorder (ADD), schizoaffective disorder, depression (e.g., lithium-resistant depression), mania, attention deficit disorders, drug addiction, dementia, agitation, apathy, anxiety, psychoses, personality disorders, bipolar disorders, unipolar affective disorder, obsessive-compulsive disorders, eating disorders, post-traumatic stress disorders, irritability, adolescent conduct disorder and disinhibition. Some diseases classified as neurodegenerative diseases, for example Alzheimer’s disease, also sometimes show aspects of psychiatric disorders as listed herein, for example disorders of memory or dementia. Some neurodegenerative diseases or manifestations thereof can, accordingly, also be referred to as psychiatric disorders. These terms are, therefore, not mutually exclusive. The state of anxiety or fear can become disordered, so that it is unusually intense or generalized over a prolonged period of time. Commonly recognized categories of anxiety disorders include specific phobia, generalized anxiety disorder, social anxiety disorder, panic disorder, agoraphobia, obsessive-compulsive disorder, post-traumatic stress disorder. Relatively long lasting affective states can also become disordered. Mood disorder involving unusually intense and sustained sadness, melancholia or despair is known as clinical depression (or major depression), and may more generally be described as emotional dysregulation. Milder but prolonged depression can be diagnosed as dysthymia. Bipolar disorder involves abnormally “high” or pressured mood states, known as mania or hypomania, alternating with normal or depressed mood. Patterns of belief, language use and perception can become disordered. Psychotic disorders centrally involving this domain include schizophrenia and delusional disorder. schizoaffective disorder is a category used for individuals showing aspects of both schizophrenia and affective disorders. Schizotypy is a category used for individuals showing some of the traits associated with schizophrenia but without meeting cut-off criteria. The fundamental characteristics of a person that influence his or her cognitions, motivations, and behaviors across situations and time - can be seen as disordered due to being abnormally rigid and maladaptive. Categorical schemes list a number of different personality disorders, such as those classed as eccentric (e.g., paranoid personality disorder, schizoid personality disorder, schizotypal personality disorder), those described as dramatic or emotional (antisocial personality disorder, Borderline personality disorder, histrionic personality disorder, narcissistic personality disorder) or those seen as fear-related (avoidant personality disorder, dependent personality disorder, obsessive-compulsive personality disorder). BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which constitute a part of this specification, illustrate several embodiments of the present disclosure and together with the description, serve to explain the principles of the present disclosure. FIGs.1A to 1C: Compounds #1, #4, #11, #12, #44, #128 and #133-135 degrade Bcl-xL in a dose-dependent manner in Jurkat and Hela cells, and some of these compounds also slightly reduce Bcl-2 protein levels in both Jurkat and Hela cells. However, none of these compounds degrades Bcl-w in Hela cells.

Liquid dosage forms for oral and parenteral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredients, the liquid dosage forms may comprise inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (e.g., cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. 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 described herein 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 described herein 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 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.
