Description:
IKZF2 and CK1-ALPHA DEGRADING COMPOUNDS AND USES THEREOF RELATED APPLICATIONS [0001] This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Applications, U.S.S.N. 63/406,582, filed September 14, 2022, and U.S.S.N. 63/439,757, filed January 18, 2023, each of which is incorporated herein by reference in its entirety. BACKGROUND [0002] The IKAROS family of proteins, including IKZF1–5, are zinc finger transcription factors that are key regulators of hematopoiesis and cell-fate decisions in the development of the adaptive immune system. The IKAROS family sustains adult human stem cell character, and dysregulation is observed in a number of hematological malignancies, including lymphomas, leukemias, and myelomas. IKZF1 and IKZF3 are essential transcription factors in multiple myeloma (MM). IKZF1 has attracted attention as a target due to its role in hematopoiesis, immune function, and tumor suppression, as well as its complex role in the regulation of transcription and chromatin remodeling. IKZF2 controls lymphocyte development, promotes quiescence, and maintains the inhibitory function of regulatory T cells. IKZF2 is frequently deleted in hypodiploid B-cell acute lymphoblastic leukemias (B- ALLs) and expression of dominant negative isoforms have been reported in T-cell acute lymphoblastic leukemia (T-ALL) patients, suggesting a role for IKZF2 as a tumor suppressor in lymphoid malignancies. IKZF2 is also associated with chronic myelogenous leukemia (CML) and is overexpressed in thyroid, urothelial, and cervical cancers. However, the regulatory role of IKZF2 in adult stem cell maintenance and the difficulty in developing inhibitors for transcription factors has prevented its broader exploration as an anti-cancer target to date. [0003] Recently, IKZF2 was established as a viable target in acute myeloid leukemia (AML) through the key role of IKZF2 in maintenance of leukemia stem cell (LSC) function. LSCs are resistant to chemotherapy and drive relapse in clinical studies, and therefore blocking self-renewal and differentiation could provide a novel therapeutic strategy. It was recently reported that IKZF2 was required for LSC function. IKZF2 depletion in human AML cell lines results in reduced proliferation, increased differentiation, increased apoptosis in vitro, and improved overall survival in mice. These properties establish IKZF2 as a bona fide anticancer target for the first time and creates a unique opportunity for the design of novel therapeutics targeting IKZF2. [0004] Casein kinase 1 (CK1) proteins are important regulators of signal transduction, involved in diverse signaling pathways and acting in most cell types. In humans, the CK1 protein family includes seven isoforms, with CK1α being the most studied to date. All CK1 proteins are serine/threonine, monomeric protein kinases. CK1 family members are involved in various cellular processes, such as mitotic checkpoint signaling, DNA repair, apoptosis and p53 pathway, protein translation, circadian rhythm, endocytosis and autophagy, immune response and inflammation, and centrosome-associated processes, and they play a key regulatory role in several developmental pathways, such as Wnt, Hedgehog, NF-κB, and Yap/Taz signaling. Dysregulation of widespread regulatory network controlled by CK1 kinases may result in various pathological conditions, including cancer development, metastasis spreading, and neurodegenerative diseases. Recent studies have suggested that targeting CK1α is a promising approach for the treatment of cancers, such as hematological malignancies. However, investigation of such treatments have been hampered by a lack of suitable CK1α inhibitors. [0005] GSPT1 is a small GTPase initially found essential for the G1 to S phase transition of the cell cycle and later reported to function as a polypeptide chain release factor 3 (eRF3). GSPT1 has been found to be overexpressed and oncogenic in a number of cancers, including hematopoietic malignancies. Acute leukemia cells are highly sensitive to GSPT1 degradation, strongly supporting this mechanism as a therapeutic approach to the treatment of hematological cancers. [0006] Immunomodulatory agents (IMIDs), such as lenalidomide, have demonstrated efficacy in myelodysplastic syndromes and in multiple myeloma through targeting of IKAROS family members IKZF1 and IKZF3; however, these agents do not promote degradation of IKZF2 or CK1α, or show substantive efficacy in AML. SUMMARY [0007] The present disclosure stems from the recognition that compounds that can degrade CK1α, IKZF1, IKZF2, and/or GSPT1, potential drug targets for the treatment of cancer (e.g., hematological malignancies), may be useful therapeutic agents in the treatment of disease (e.g., acute myeloid leukemia). The present disclosure describes new compounds that can induce the degradation of CK1α, IKZF1, IKZF2, and/or GSPT1 in cells. Thus, the present disclosure provides new compounds, compositions, kits, uses, and methods for the treatment of proliferative diseases (e.g., cancer, such as acute myeloid leukemia).

The chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75 th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, University Science Books, Sausalito, 1999; Smith and March, March’s Advanced Organic Chemistry, 5 th Edition, John Wiley & Sons, Inc., New York, 2001; Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989; and Carruthers, Some Modern Methods of Organic Synthesis, 3 rd Edition, Cambridge University Press, Cambridge, 1987. [0036] Compounds described herein can comprise one or more asymmetric centers, and thus can exist in various stereoisomeric forms, e.g., enantiomers and/or diastereomers. For example, the compounds described herein can be in the form of an individual enantiomer, diastereomer or geometric isomer, or can be in the form of a mixture of stereoisomers, including racemic mixtures and mixtures enriched in one or more stereoisomer. Isomers can be isolated from mixtures by methods known to those skilled in the art, including chiral high pressure liquid chromatography (HPLC) and the formation and crystallization of chiral salts; or preferred isomers can be prepared by asymmetric syntheses.

[0082] In certain embodiments, the substituent present on a sulfur atom is a sulfur protecting group (also referred to as a “thiol protecting group”). Sulfur protecting groups include, but are not limited to, −R aa , −N(R bb )2, −C(=O)SR aa , −C(=O)R aa , −CO2R aa , −C(=O)N(R bb )2, −C(=NR bb )R aa , −C(=NR bb )OR aa , −C(=NR bb )N(R bb )2, −S(=O)R aa , −SO2R aa , −Si(R aa ) 3 , −P(R cc ) 2 , −P(R cc ) 3 + X , −P(OR cc ) 2 , −P(OR cc ) 3 + X , −P(=O)(R aa ) 2 , −P(=O)(OR cc ) 2 , and −P(=O)(N(R bb ) 2)2, wherein R aa , R bb , and R cc are as defined herein. Sulfur protecting groups are well known in the art and include those described in detail in Protecting Groups in Organic Synthesis, T. W. Greene and P. G. M. Wuts, 3 rd edition, John Wiley & Sons, 1999, incorporated herein by reference. In certain embodiments, a sulfur protecting group is acetamidomethyl, t-Bu, 3-nitro-2-pyridine sulfenyl, 2-pyridine-sulfenyl, or triphenylmethyl. [0083] A “counterion” or “anionic counterion” is a negatively charged group associated with a positively charged group in order to maintain electronic neutrality. An anionic counterion may be monovalent (i.e., including one formal negative charge). An anionic counterion may also be multivalent (i.e., including more than one formal negative charge), such as divalent or trivalent. Exemplary counterions include halide ions (e.g., F , Cl , Br , I ), NO3 , ClO4 , OH , H2PO4 , HCO3 , HSO4 , sulfonate ions (e.g., methansulfonate, trifluoromethanesulfonate, p–toluenesulfonate, benzenesulfonate, 10–camphor sulfonate, naphthalene–2–sulfonate, naphthalene–1–sulfonic acid–5–sulfonate, ethan–1–sulfonic acid– 2–sulfonate, and the like), carboxylate ions (e.g., acetate, propanoate, benzoate, glycerate, lactate, tartrate, glycolate, gluconate, and the like), BF4 , PF4 , PF6 , AsF6 , SbF6 , B[3,5- (CF 3 ) 2 C 6 H 3 ] 4 ] , B(C 6 F 5 ) 4 , BPh 4 , Al(OC(CF 3 ) 3 ) 4 , and carborane anions (e.g., CB 11 H 12 or (HCB 11 Me 5 Br 6 ) ). Exemplary counterions which may be multivalent include CO 3 2− , HPO 4 2− , PO4 3− , B4O7 2− , SO4 2− , S2O3 2− , carboxylate anions (e.g., tartrate, citrate, fumarate, maleate, malate, malonate, gluconate, succinate, glutarate, adipate, pimelate, suberate, azelate, sebacate, salicylate, phthalates, aspartate, glutamate, and the like), and carboranes. [0084] The term “leaving group” is given its ordinary meaning in the art of synthetic organic chemistry and refers to an atom or a group capable of being displaced by a nucleophile. See, for example, Smith, March’s Advanced Organic Chemistry 6th ed. (501- 502). Examples of suitable leaving groups include, but are not limited to, halogen (such as F, Cl, Br, or I (iodine)), alkoxycarbonyloxy, aryloxycarbonyloxy, alkanesulfonyloxy, arenesulfonyloxy, alkyl-carbonyloxy (e.g., acetoxy), arylcarbonyloxy, aryloxy, methoxy, N,O-dimethylhydroxylamino, pixyl, and haloformates. In some cases, the leaving group is a sulfonic acid ester, such as toluenesulfonate (tosylate, -OTs), methanesulfonate (mesylate, - OMs), p-bromobenzenesulfonyloxy (brosylate, -OBs), -OS(=O)2(CF 2 )3CF 3 (nonaflate, -ONf), or trifluoromethanesulfonate (triflate, -OTf). In some cases, the leaving group is a brosylate, such as p-bromobenzenesulfonyloxy. In some cases, the leaving group is a nosylate, such as 2-nitrobenzenesulfonyloxy. The leaving group may also be a phosphineoxide (e.g., formed during a Mitsunobu reaction) or an internal leaving group such as an epoxide or cyclic sulfate. Other non-limiting examples of leaving groups are water, ammonia, alcohols, ether moieties, thioether moieties, zinc halides, magnesium moieties, diazonium salts, and copper moieties. Further exemplary leaving groups include, but are not limited to, halo (e.g., chloro, bromo, iodo) and activated substituted hydroxyl groups (e.g., –OC(=O)SR aa , –OC(=O)R aa , – OCO2R aa , –OC(=O)N(R bb )2, –OC(=NR bb )R aa , –OC(=NR bb )OR aa , –OC(=NR bb )N(R bb )2, –OS(=O)R aa , –OSO2R aa , –OP(R cc )2, –OP(R cc )3, –OP(=O)2R aa , –OP(=O)(R aa )2, –OP(=O)(OR cc ) 2 , –OP(=O) 2 N(R bb ) 2 , and –OP(=O)(NR bb ) 2 , wherein R aa , R bb , and R cc are as defined herein). [0085] As used herein, use of the phrase “at least one instance” refers to 1, 2, 3, 4, or more instances, but also encompasses a range, e.g., for example, from 1 to 4, from 1 to 3, from 1 to 2, from 2 to 4, from 2 to 3, or from 3 to 4 instances, inclusive. [0086] A “non-hydrogen group” refers to any group that is defined for a particular variable that is not hydrogen. [0087] These and other exemplary substituents are described in more detail in the Detailed Description, Examples, and claims. The invention is not intended to be limited in any manner by the above exemplary listing of substituents. Other definitions [0088] The following definitions are more general terms used throughout the present application. [0089] As used herein, the term “salt” refers to any and all salts, and encompasses pharmaceutically acceptable salts. [0090] 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 invention 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. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N + (C 1-4 alkyl)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, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions, such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. [0091] 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. The compounds described herein 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 isolatable solvates. Representative solvates include hydrates, ethanolates, and methanolates. [0092] 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⋅x H2O, wherein R is the compound, and x is a number greater than 0. A given compound 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 H 2 O) and hexahydrates (R⋅6 H 2 O)). [0093] 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. [0094] 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”. [0095] 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”. [0096] 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. Various polymorphs of a compound can be prepared by crystallization under different conditions. [0097] 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. C 1-8 alkyl, C 2-8 alkenyl, C 2-8 alkynyl, aryl, C7-12 substituted aryl, and C7-12 arylalkyl esters of the compounds described herein may be preferred. [0098] The terms “composition” and “formulation” are used interchangeably. [0099] 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. The non-human animal may be a male or female at any stage of development. The non-human animal may be a transgenic animal or genetically engineered animal. The term “patient” refers to a human subject in need of treatment of a disease. The subject may also be a plant. In certain embodiments, the plant is a land plant. In certain embodiments, the plant is a non- vascular land plant. In certain embodiments, the plant is a vascular land plant. In certain embodiments, the plant is a seed plant. In certain embodiments, the plant is a cultivated plant. In certain embodiments, the plant is a dicot. In certain embodiments, the plant is a monocot. In certain embodiments, the plant is a flowering plant. In some embodiments, the plant is a cereal plant, e.g., maize, corn, wheat, rice, oat, barley, rye, or millet. In some embodiments, the plant is a legume, e.g., a bean plant, e.g., soybean plant. In some embodiments, the plant is a tree or shrub. [00100] 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. [00101] 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, which is the object to which a compound, particle, and/or composition of the invention is delivered. A tissue may be 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. In certain embodiments, the tissue is the central nervous system. In certain embodiments, the tissue is the brain. [00102] The term “administer,” “administering,” or “administration” refers to implanting, absorbing, ingesting, injecting, inhaling, or otherwise introducing a compound described herein, or a composition thereof, in or on a subject. [00103] 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 may be administered after one or more signs or symptoms of the disease have developed or have been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of the disease. For example, treatment may be administered to a susceptible subject prior to the onset of symptoms (e.g., in light of a history of symptoms). Treatment may also be continued after symptoms have resolved, for example, to delay or prevent recurrence. [00104] The terms “condition,” “disease,” and “disorder” are used interchangeably. [00105] 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, the pharmacokinetics of the compound, the condition being treated, the mode of administration, and the age and health 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. [00106] 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 promoting the degradation of a protein (e.g., IKZF2). In certain embodiments, a therapeutically effective amount is an amount sufficient for treating a cancer. [00107] A “prophylactically effective amount” of a compound described herein is an amount sufficient to prevent a condition, or one or more signs or 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. [00108] 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. [00109] 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 (e.g., cancer). [00110] 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, but are not limited to, 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. [00111] 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.

Biologics may be isolated from a variety of natural sources (e.g., human, animal, microorganism) and may be produced by biotechnological methods and other technologies. [00116] The term “small molecule” or “small molecule therapeutic” refers to molecules, whether naturally occurring or artificially created (e.g., via chemical synthesis) that have a relatively low molecular weight. Typically, a small molecule is an organic compound (i.e., it contains carbon). The small molecule may contain multiple carbon-carbon bonds, stereocenters, and other functional groups (e.g., amines, hydroxyl, carbonyls, and heterocyclic rings, etc.). In certain embodiments, the molecular weight of a small molecule is not more than about 1,000 g/mol, not more than about 900 g/mol, not more than about 800 g/mol, not more than about 700 g/mol, not more than about 600 g/mol, not more than about 500 g/mol, not more than about 400 g/mol, not more than about 300 g/mol, not more than about 200 g/mol, or not more than about 100 g/mol. In certain embodiments, the molecular weight of a small molecule is at least about 100 g/mol, at least about 200 g/mol, at least about 300 g/mol, at least about 400 g/mol, at least about 500 g/mol, at least about 600 g/mol, at least about 700 g/mol, at least about 800 g/mol, or at least about 900 g/mol, or at least about 1,000 g/mol. Combinations of the above ranges (e.g., at least about 200 g/mol and not more than about 500 g/mol) are also possible. In certain embodiments, the small molecule is a therapeutically active agent such as a drug (e.g., a molecule approved by the U.S. Food and Drug Administration as provided in the Code of Federal Regulations (C.F.R.)). The small molecule may also be complexed with one or more metal atoms and/or metal ions. In this instance, the small molecule is also referred to as a “small organometallic molecule.” Preferred small molecules are biologically active in that they produce a biological effect in animals, preferably mammals, more preferably humans. Small molecules include, but are not limited to, radionuclides and imaging agents. In certain embodiments, the small molecule is a drug. Preferably, though not necessarily, the drug is one that has already been deemed safe and effective for use in humans or animals by the appropriate governmental agency or regulatory body. For example, drugs approved for human use are listed by the FDA under 21 C.F.R. §§ 330.5, 331 through 361, and 440 through 460, incorporated herein by reference; drugs for veterinary use are listed by the FDA under 21 C.F.R. §§ 500 through 589, incorporated herein by reference. All listed drugs are considered acceptable for use in accordance with the present disclosure.

Methods of Treatment [00288] Acute myeloid leukemia (AML) is a genetically complex and heterogeneous set of diseases characterized by a diverse set of mutations. The 5-year overall survival in adult AML is less than 20% and has only improved modestly in the past 30 years, and approximately one third of AML cases are unresponsive to standard treatments. Acquisition of a gene expression program that corresponds to a gain of self-renewal properties imparts a worse clinical outcome in AML patients and correlates with therapy resistance and relapse. Therefore, there is an unmet need to develop new therapies for AML patients. Targeting the mechanisms that contribute to self-renewal and disease progression can provide a new strategy for therapeutic intervention in leukemia. [00289] Recently, IKZF2 was established as a viable target in acute myeloid leukemia (AML) through the key role of IKZF2 in maintenance of leukemia stem cell (LSC) function. As such, degradation of IKZF2 is an attractive method for the development of new anticancer therapy. Accordingly, use of a compound that degrades IKZF2 provides a method of treating cancers that rely on IKZF2 activity. [00290] In addition, CK1α was discovered to be a promising autophagy regulator in cancer cells (e.g., lung, breast, multiple myeloma, colon). CK1α regulates diverse signaling processes such as Wnt-signaling, cell cycle, and apoptosis. CK1α may also be involved in tumor progression and be overexpressed in colorectal cancer. Recent studies show that CK1α inactivation is associated with autophagy inhibition that correlates with the suppression of cancer cell growth. Autophagy is an important factor influencing chemotherapy resistance to 5-FU in colorectal cancer. Since autophagy is regulated by CK1α, its inhibition or degradation provides a therapeutic option for treatment of 5-FU resistant colorectal cancer. [00291] As such, degradation of CK1α is an attractive method for the development of new anticancer therapies. Accordingly, use of a compound that degrades CK1α provides a method of treating cancers that rely on CK1α activity. [00292] IKZF1 has attracted attention as a target due to its role in hematopoiesis, immune function, and tumor suppression, as well as its complex role in the regulation of transcription and chromatin remodeling. IKZF1 has been established as one of the most clinically relevant tumor suppressors in high-risk acute lymphoblastic leukemia (ALL). Its dysfunction has also been linked to the development of chronic lymphocytic leukemia (CLL). [00293] GSPT1 is a small GTPase initially found essential for the G1 to S phase transition of the cell cycle and later reported to function as a polypeptide chain release factor 3 (eRF3). In this role, GSPT1 associates with eRF1 to mediate stop codon recognition and nascent protein release from the ribosome. GSPT1 has also been shown to play several additional roles in critical cellular processes such as cell cycle regulation, cytoskeleton organization, and apoptosis. Changes in the expression pattern of translation factors can lead to several changes in the tumor cells, such as an increase in the overall rate of protein synthesis and/or overexpression of proteins involved in cell growth and proliferation. Indeed, GSPT1 has been found to be overexpressed and oncogenic in a number of cancers, including gastric, colorectal, lung, and breast cancers. GSPT1 is overexpressed in many pediatric cancers, but mostly in hematopoietic malignancies including B-ALL, T-ALL, and AML. Acute leukemia cells are highly sensitive to GSPT1 degradation, strongly supporting this mechanism as a therapeutic approach to the treatment of hematological cancers.

The examples described in this application are offered to illustrate the compounds, pharmaceutical compositions, and methods provided herein and are not to be construed in any way as limiting their scope. Compound Synthesis [00311] Commercial solvents and reagents were used as received. N,N-Dimethylformamide (DMF, Beantown Chemical, catalog no. BT138690) and dichloromethane (DCM, Fisher Chemical, catalog no. D138-4) were vigorously purged with argon for 1 h, followed by passage under argon pressure through two packed columns of neutral alumina (Pure Process Technology). [00312] Reactions were performed in a single-neck, flame-dried, round-bottom flask fitted with a rubber septum under argon unless otherwise noted. Analytical thin-layer chromatography (TLC) was performed using glass plates pre-coated with silica gel (0.25 mm, 60 Å pore size) impregnated with a fluorescent indicator (254 nm). TLC plates were visualized by exposure to ultraviolet light (UV) or submersion in ninhydrin or p-anisaldehyde followed by brief heating with a heat gun (10—15 s). Organic solutions were concentrated by rotary evaporation at 30 ºC to 35 ºC. For purification, normal phase flash-column chromatography was performed. Some normal phase column chromatography purifications were performed using a Teledyne ISCO CombiFlash NextGen 300+ instrument. Normal phase purification used silica gel (60 Å, 40–63 μm particle size) purchased from Silicycle. Purification with the CombiFlash was performed using silica gel (60 Å, 40–63 μm particle size) purchased from Silicycle and 12-gram RediSep Rf silica flash columns (60 Å, 40–63 μm particle size) purchased from Teledyne ISCO. All analogs tested in cells were purified by preparative HPLC on a Waters Prep 150 LC system and Agilent Infinity II system with a XBridge BEH C18 OBD prep column (130 A °, 5 mm, 19 mm 3100 mm) and an Agilent C18 prep column (100 A°, 5 mm, 30 mm 3100 mm).

HRMS-ESI (m/z): [M+H]+ calculated for C16H16N3O4314.1135; found, 314.1135. Selective degradation of IKZF2 [00321] Evaluation of previously discovered cereblon ligands showed that degradation of IKZF2 was sensitive to the exact substitution pattern of the projection from the 5-position of the isoindolinone, while degradation of IKZF1 appeared to be more permissive. These compounds were without an amide moiety at the 5-position of the isoindolinone, and were not sterically inhibiting recruitment of IKZF1. Based on further modeling, it was hypothesized that rigidifying the core structure via an amide linkage would reduce the overall conformational flexibility, and thus potentially serve to fix the compound in a favorable conformation to recruit IKZF2 and block recruitment of IKZF1. Compounds of the present disclosure, which have an amide moiety, possess increased selectivity for IKZF2 over IKZF1. Diversification of the compound scaffold [00322] Known compounds such as DEG-35 suffered from limited solubility and additional scaffolds were explored. DEG-64 (phenylamide) and DEG-66 (acyl amide) indicated that a bicyclic substituent was useful for selective degradation of IKZF2 and CK1α. Additional analogs (DEG51-56, 59, 61-64, 66, 67, 72, 87) which contain heteroatoms, sp 3 -hybridized carbons, and non-continuous pi systems, were tested at 100 nM or 1 μM in the panel of reporter cell lines. The homonaphthalene 67, vinyl phenyl 56, diphenyl ethers 55 and 61, 2H- chromene 52, and benzofuran 59 showed good degradation activity for CK1α and/or IKZF2, while sparing IKZF1 and/or GSPT1 (FIG. 8A). All analogs were fully soluble in DMSO to at least 50 mM. [00323] Diversification around the 2H-chromene 52 showed potency and selectivity for IKZF2 and CK1α (FIG. 8B). To probe substituent toleration around the 2H-chromene core, additional analogs (e.g., DEG-74, 77-84, and 86) were generated. The 2H-chromene analogs induced potent IKZF2 and CK1α degradation (DC50 IKZF2 = 6–34 nM, DC50 CK1α = 1–10 nM, Tables 1-2), reflecting a remarkable tolerance to substitution about the 2H-chromene scaffold (FIG. 8B). Tables 1-3 show degradation data for compounds of the disclosure. [00324] Based on these data, DEG-77, was further characterized. Global proteomics of DEG-77 after 2 h treatment in MOLM-13 cells reflected its high selectivity, rapid degradation of CK1α, and the response through elevated TP53 (FIG. 8C). Notably, degradation of IKZF2 is only observed after 24 h in MOLM-13 cells. DEG-77 additionally possessed improved in vitro metabolic stability (t1/2 > 6 h) and in vivo half-life (t1/2 = 8 h) which correlate with in vivo therapeutic efficacy leading to a significant increase in survival upon treatment in AML mouse models. Thus, DEG-77 is a potent and selective IKZF2 and CK1α degrader with favorable metabolic stability and solubility properties. Table 1. 98 79.7 50.9 68.1 35.8 Table 2. Table 3. Therapeutic potential of degradation of CK1α and IKZF2 [00325] In addition to investigation of DEG-77 for efficacy in AML, DEG-77 was evaluated in other indications as activation of p53-dependent apoptosis in cancer cells has been an area of intense research for decades. Accordingly, there is still an unmet need for targeted therapeutics that reactivate the p53 pathway. CK1α degradation by DEG-77 represents a different but orthogonal mechanism of action for the activation of p53, potentially providing the opportunity to overcome past obstacles with therapies such as MDM2 inhibitors in various cancer indications. [00326] To examine additional cancers that may be sensitive to DEG-77, data generated from evaluating DEG-35 in a PRISM Screen was used. The endometrioid ovarian cancer cell line A2780, small cell lung cancer cell line NCI-H1048, and DLBCL cell line OCI-LY3 were evaluated for sensitivity to DEG-77 and the methylated negative control Me-DEG-35 via MTT assay (FIG. 9A, 9C). A2780 and OCI-LY3 both displayed exquisite sensitivity to DEG- 77 with EC 50 values of 27 nM and 14 nM, respectively, while the negative control compound Me-DEG-35 showed limited activity. However, surprisingly, NCI-H1048 cells were selectively sensitive to DEG-35 and not DEG-77. Thus, all cell lines were treated with potent GSPT1 degrader CC-90009 to probe if they are sensitive to its degradation (FIG. 9B, 9C). A2780 and OCI-LY3 cells displayed higher EC 50 values of 269 nM and 36 nM respectively for CC-90009, suggesting their preferential sensitivity to DEG-35 (EC50 values of 12 nM and 8 nM) and DEG-77 was due to the degradation of CK1α and not GSPT1. In contrast, NCI- H1048 cells were preferentially sensitive to CC-90009 and DEG-35 with EC 50 values of 7 nM and 49 nM, respectively. Additionally, when blotting for CK1α and GSPT1 degradation in NCI-H1048 cells treated with DEG-77 and DEG-35, DEG-35 led to significant GSPT1 degradation at nanomolar concentrations while DEG-77 did not affect protein levels (FIG. 10A). This suggests that A2780 and OCI-LY3 cells are sensitive to CK1α degradation while NCI-H1048 cells are not. [00327] CK1α degradation upon DEG-77 treatment was validated by Western blot and demonstrated that GSPT1 is largely spared by DEG-77 but does begin to degrade at higher concentrations of DEG-35 in both cell lines (FIG. 9D). Additionally, p53 activation was demonstrated in both cell lines upon DEG-77 treatment via Western blot and real-time quantitative polymerase chain reaction (RT-qPCR), indicating that CK1α degradation activates p53 in indications beyond AML (FIGs. 9F, 9G. and 10B). Notably, A2780 cells express IKZF2 which was also degraded upon DEG-77 treatment, which may therefore contribute to the overall antiproliferative effects in this cell line (FIG. 9E). Due to apparent p53 activation upon CK1α degradation, the sensitivity of OCI-LY3 and A2780 cells to MDM2 inhibitor idasanutlin (which activates the p53 pathway in cells via a distinct mechanism) was evaluated. A2780 cells had no demonstrable sensitivity and OCI-LY3 had very limited sensitivity to idasanutlin, indicating that MDM2 inhibition is not sufficient to induce apoptosis in these cell lines (FIG. 9B). Collectively, these results demonstrate that DEG-77 has efficacy against ovarian cancer cell line A2780 and DLBCL cell line OCI-LY3 which are both largely insensitive to MDM2 inhibition, suggesting DEG-77 may overcome certain limitations of MDM2 inhibitors. Compounds have improved efficacy over DEG-35 and can block leukemic stem cell activity [00328] DEG-77 exhibited a 10-fold increase in solubility in DMSO compared to that of DEG-35 and maintained comparable activity against IKZF2 and CK1α in MOLM-13 cells at 24 hr. Similar potency in inducing myeloid differentiation, apoptosis, and cytotoxicity with comparable IC50 values were also observed (IC50 DEG-35 = 6 nM, IC50 DEG-77 = 4 nM, FIG. 6A–E). Additionally, DEG-77 had increased selectivity against IKZF2 (DC50 = 15.3 nM) and CK1α (DC 50 = 10 nM) over other known neosubstrates (e.g., GSPT1, IKZF1, IKZF3, FIG. 7A). Degradation of IKZF2 and CK1α by DEG-77 was CRBN-dependent and occurred post-translationally (FIG. 7B–E). Furthermore, DEG-77 treatment also reduced levels of HOXA9 and c-MYC as observed in DEG-35 treated MOLM-13 cells (FIG. 6F). Furthermore, DEG-77 had similar activity and kinetics as DEG-35 resulting in increased apoptosis, myeloid differentiation, and induction of the TP53 pathway, and comparable preferential sensitivity to leukemia versus healthy cells (FIGs. 11A–H and S7G–L). [00329] To measure its efficacy in vivo, pharmacokinetic and pharmacodynamic assays were performed (FIG. 6G and FIG. 7F). Single treatment of DEG-77 at 223 mg/kg in BL6 mice transplanted with MLL-AF9 Crbn I391V cells led to degradation of IKZF2 and CK1α in bone marrow leukemic cells at 24, 48, and 72 h (FIG.6H). At the 24 h time point following DEG-77 injection, leukemic cells in blood, bone marrow, and spleen underwent increased apoptosis and myeloid differentiation (FIGs. 7G, 7H). Moreover, sorted leukemic cells from the bone marrow and spleen of DEG-77 treated mice had reduced colony forming ability suggesting reduced in vitro self-renewal (FIG. 6I). [00330] To determine the in vivo efficacy of DEG-77 on survival of leukemic mice, the MLL-AF9 mice were treated with DEG-77 once per week at 223 mg/kg. Interestingly, DEG- 77 treated mice had significantly prolonged survival of 66 days compared to 35 days of vehicle treated mice (FIG. 6J) without total body weight loss (FIG. 7I). Importantly, the secondary transplant of DMSO and DEG-77 treated mice maintained a significant survival difference in which DEG-77 mice treated cells in the primary had a pronounced delay in leukemia progression, indicating that DEG-77 can also reduce leukemic stem cell activity (FIG. 6K). [00331] DEG-77 treatment also increased survival and reduced leukemia burden in bone marrow of MOLM-13 transplanted mice without gross weight loss (FIGs. 12A, 14A–B). Both IKZF2 and CK1α were degraded in bone marrow leukemic cells after DEG-77 treatment (FIG. 12B). In the PDX AML model, PDX cells were allowed to engraft for 4 weeks and then treated with DMSO or DEG-77 weekly. This resulted in a significant extension of survival and reduced disease burden for the animals treated with DEG-77 (FIGs. 12C, 14C–D). PDX cells exhibited >85% engraftment prior to DEG-77 treatment in the bone marrow and only around 40% engraftment after a single injection (FIG. 12D) indicating that DEG-77 can reduce leukemic cells in the bone marrow. [00332] Toxicity was determined by testing Crbn I391V mice with four rounds of DMSO or DEG-77 resulting in reduced HSC and MPP1 frequency in the stem cell compartment and CMP and MEP in the progenitor compartment (FIGs. 14E–G). However, we did not observe significant changes in absolute number of LSK and HSC in the DEG-77 treated mice (FIGs. 12H–I). A decrease in B cells and increase in myeloid cells was found which resulted in a modest reduction of WBC counts (FIGs. 12J–M). Importantly, platelets and RBC counts remained unchanged without a major reduction in total body weight (FIGs. 12N–P). [00333] To further test the therapeutic index, a significant increase in survival was found along with reduction of leukemic cell burden in the spleen when DEG-77 was administered to Crbn I391V mice transplanted with MLL-AF9 Crbn I391V cells (FIGs. 12E–F). These data suggest that DEG-77 has efficiency in selectively killing leukemic cells in an in vivo model where all cells are sensitive to the degrader. [00334] Taken together, the disclosure data provides compounds for multi-targeted degradation of IKZF2/CK1α to enhance efficacy against cancer (e.g., AML). In particular, the disclosure reports the design and synthesis of a series of molecular glue degraders that target IKZF2 and CK1α. Through a series of SAR studies, it was found that extension of lenalidomide with a naphthamide from the 5-position of the isooxindole ring promoted IKZF2 and CK1α degradation. It was further found that linkage of the naphthyl group to the isooxindole through an amide greatly increased degradation potency for IKZF2 and CK1α while preventing IKZF1 recruitment, as in DEG-35. The rigid amide bond may introduce additional hydrogen bonds to stabilize the ternary complex with CK1α and also rigidify the structure to adopt a preferential conformation for forming the ternary complex with IKZF2 over IKZF1. Further studies to develop degraders that exhibited the same activity as DEG-35, but with superior solubility and pharmacokinetic properties, were spurred by the finding that the methoxy group of DEG-35 was a metabolic liability. 2H-Chromene analogs of DEG-35 possessed similar degradation profiles, which were also sensitive to substituents and substitution patterns. These analogs showed potent IKZF2 and CK1α degradation, as well as high selectivity for the desired targets over other neosubstrates, namely IKZF1 and GSPT1, which highlights the difficulty in designing a molecular glue that both degrades the target of interest and avoids degradation of undesired neosubstrates. In addition, compounds of the disclosure (e.g., DEG-77) have anti-proliferative effects in cancer types beyond AML. [00335] The development of potent degraders for CK1α additionally suggest that kinases may be a broad class of proteins amenable to degradation by molecular glues that ligand to CRBN. [00336] Multicomponent and combination therapies are a common strategy to treat multigenic diseases and may extend to multi-targeting degraders. Multi-targeting degraders offer the unique opportunity to not only inhibit enzymatic activity but also ablate scaffolding functions of additional proteins. The ability to degrade targets belonging to multiple classes of proteins may broaden the number of pathways that can be targeted with one molecule and may have the potential to act synergistically. Additionally, the use of a single molecule to target multiple proteins may result in reduced toxicity and superior pharmacokinetic and safety profiles. Experimental Methods [00337] Culture and transduction of human leukemia cell lines: MOLM-13, OCI- AML5, Kasumi-1, NB4, KG-1A, NOMO-1 and OCI-AML3 cells were cultured in RPMI media (Cell gro) supplemented with 10% FBS, glutamine and penicillin/streptomycin and grown at 37 o C with 5% CO2. Cells were transduced with viruses expressing empty vector, CK1α wt, CK1α G40N, murine or human IKZF2 wt or IKZF2 mutants by spinning in RPMI with 10% FBS together with viral supernatant containing 10 ug/ml polybrene at 1600 RPM for 1 hr. Media was changed 24 hrs later, and after 72 hrs post transduction cells were sorted for either GFP or RFP and used for experiments. [00338] Transduction of HEK293T cells for fluorescence assays: HEK293T cells were cultured in a 10 cm plate in antibiotic-free DMEM supplemented with 10% FBS and grown to between 70-90% confluence. VSV-G (4 μg), Gag-Pol (6 μg), desired vector (IKZF2-GFP, IKZF1-GFP, GFP-CK1a, 10 μg), and TransitPro (30 μL) were diluted into OptiMEM to a final volume of 1 mL. After tapping to mix and incubation at room temperature (15 min), the DNA/OptiMEM solution was added dropwise to HEK293T cells and swirled gently to mix. Cells were incubated at 37 o C and 5% CO2 for 5-8 h. Media was replaced with antibiotic-free DMEM supplemented with 10% FBS (10 mL). Cells were incubated for an additional 24-48 h prior to harvesting virus. To harvest, media was collected and centrifuged (500 x g, 5 min). The supernatant was removed, passed through a 0.45 μm filter, and aliquoted prior to being snap frozen in liquid nitrogen and stored at -80 o C prior to use. An aliquot of lentivirus (1 mL) was thawed and used to create a 6-well viral dilution plate containing 0, 1:3, 1:5, 1:10, 1:50, and 1:100 viral dilutions in antibiotic-free DMEM supplemented with 10% FBS and polybrene (10 μg/mL) for a final volume of 500 μL per well. 1 x 105 HEK293T cells in antibiotic-free DMEM (1 mL) supplemented with 10% FBS and polybrene (10 μg/mL) were added to each well and rocked gently to mix. Cells were incubated with virus at 37 o C and 5% CO2 for 48 h. The media was changed and cells were incubated for an additional 24 h. To begin the selection, media was changed to DMEM supplemented with 10% FBS, 10% penicillin/streptomycin, and puromycin (2μg/mL). Media was periodically refreshed until cells in control well (no virus) appeared dead, generally about 4-5 days after beginning selection. Healthy cells from all wells of virus were harvested and sorted for GFP expression using fluorescence-activated cell sorting (FACS) on the Fortessa flow cytometer at the Harvard Bauer Core and binned into “high”, “medium”, and “low” expression levels as compared to a non-transduced HEK293T cell line. Each cell pool was then evaluated for POI-GFP degradation via Western blot and flow cytometry and subsequently used for experiments. [00339] Site-directed mutagenesis of plasmids: Site-directed mutagenesis of pMSCV- IRES-RFP15-mouse IKZF2, pHFUW-human IKZF2-IRES-GFP and pLC-Flag-CSNK1A1 constructs was performed to obtain the mutants. QuikChange Lightning and Multi Site- Directed Mutagenesis Kits (#210513 and #210518, Agilent Technologies) were used. [00340] Isolation of cord blood-derived CD34+ HSPC cells: Five mixed cord blood units (each unit is from a healthy donor) were used for purifying cord blood CD34+ HSPCs. Mononuclear cells were purified from cord blood by using Hespan and Ficoll-Hypaque Plus density centrifugation, followed by positive selection using the Auto MACS Pro Separator and isolation Kit (Miltenyi). [00341] Culture of primary AML patient cells: Culture of all primary AML patient samples, unless otherwise noted, were collected under the Biospecimen collection/banking study 09-141. The use of the samples for research purposes is covered under the Biospecimen research protocol 16-354. Frozen AML patient cells were thawed in warm RPMI containing 20% FBS and penicillin/streptomycin, washed, counted and cultured in StemSpan SFEMII containing StemSpan CD34+ expansion supplement (Stem Cell tech) at 1X106 cells/ml. [00342] Generation of MLL-AF9 Crbn I391V leukemic cells: Lin-Sca+Kit+ (LSK) cells were isolated from bone marrow cells of wildtype or Crbn I391V mice that were 6 to 8 weeks old. Briefly, bone marrow cells were enriched for c-Kit positive cells by incubating with CD117/c-Kit microbeads and then processed through the autoMACS Pro Separator (Miltenyi Biotec), following the manufacturer’s instructions. CKit enriched cells were stained with Lineage antibody cocktail (CD3, CD4, CD8, Gr1, B220, CD19, TER119 conjugated with PeCy5), Sca1-Pac Blue, CD34-FITC, SLAM-APC, CD48-PE, and c-KIT-APC-Cy7. After staining, cells were sorted for LSK cells using a BD FACS Aria II instrument. Sorted LSK cells were incubated overnight in Stemspan SFEM medium (Stem Cell Technologies) with 10 ng/ml IL-3, 10 ng/ml IL-6, 50 ng/ml SCF, 10 ng/ml thrombopoietin (TPO), and 20 ng/ml FLT-3 ligand. Cells were plated on retronectin-coated plates together with supernatant containing retrovirus expressing MLL-AF9 together with GFP (a gift from Scott Armstrong, Dana Farber Cancer Institute) and spun for 1hr at 2500 RPM. After two cycles of spinfection, the cells were grown in M3434 methylcellulose medium (Stem Cell Technologies) for a week. Cells were sorted for GFP positivity and sorted 200,000 GFP positive cells were injected retro-orbitally with 250,000 bone marrow support cells into lethally irradiated 6- week-old female C57BL/6 mice. [00343] Culture of murine MLL-AF9 leukemic cells: Mouse leukemic bone marrow cells from MLL-AF9 wt and MLL-AF9 Crbn I391V mice were grown in RPMI (Cellgro) medium containing 10% FBS, 6 ng/ml IL-3, 10 ng/ml SCF, 10 ng/ml IL-6 and 10 ng/ml GM- CSF. [00344] Western blot analysis: One million human AML cell lines or murine leukemic cells were counted and treated with drugs at the indicated concentrations for 24hr. Cells were pelleted, washed with PBS and lysed in Laemmli buffer. Boiled lysates were processed through Qia Shredder and electrophoresed on 4%–15% gradient SDS-PAGE gels. Proteins were transferred onto PVDF membrane and blotted with specified Abs. [00345] 1.0 x 10 6 MOLM-13 cells were suspended in 1 mL of media and treated with a thousand-fold stock solution in DMSO (1 μL). Cells were incubated at 37 ºC for 24 h. Cells were harvested into a microcentrifuge tube and centrifuged (21,130 g) for 2 min. Media was aspirated and cells were washed with PBS (2 × 1 mL). Cells were then lysed in Laemmeli buffer (150 μL) by vigorous vortexing for 10 min. Lysates were boiled at 95 ºC for 5 min. Lysates were then run on a 4%—15% gradient SDS-PAGE gel. [00346] 2.0 x 10 6 A2780 and TOV-21G cells were suspended in 2 mL of media and treated with a thousand-fold stock solution in DMSO (2 μL). Cells were incubated at 37 ºC for 24 h. Media was harvested into a microcentrifuge tube and centrifuged (21,130 g) for 3 min. Media was aspirated. Cells were trypsinized with 750 μL of 0.25% trypsin for 3 min. Trypsin was quenched with 750 μL of media. Media was harvested into the microcentrifuge tubes and centrifuged (21,130 g) for 3 min. Media was aspirated and cells were washed with PBS (2 × 1 mL). Cells were then lysed in Laemmeli buffer (200 μL) by vigorous vortexing for 20 min. Lysates were boiled at 95 ºC for 10 min. Lysates were then run on a 4%—15% gradient SDS- PAGE gel. [00347] Viability Assay: 10,000 cells (e.g., MOLM-13 cells, MLL-AF9 leukemic cells or normal BM cells) were plated onto flat-bottom 96-well plates in media with increasing concentration of compound up to 100 μM. Cells were cultured for 72 h at 37 o C in a 5% CO2 incubator. For measuring viability, Cell-Titer Glo kit (Promega) or MTT kit was used following manufacturer’s instructions. For Cell-Titer Glo assay, cells were cooled to room temperature for 20–30 min, 100 μL of the cultured cells were transferred to opaque-white bottom 96-well plates and mixed with 100 μL of Cell-Titer Glo reagent. The mixture was incubated for 15 min at room temperature and read using a Synergy H1 Hybrid reader (BioTek) for luminescence. Data was normalized as percentage viability and graphed by non- linear regression curves in Graph Pad PRISM 7.0. [00348] Flow cytometry for apoptosis and differentiation: For measuring differentiation, MOLM-13 cells treated with compound for 48 hrs were stained with anti-CD13-FITC, anti- CD33-APC, anti-CD14-FITC or anti-CD11b/Mac1-APC. For murine MLL-AF9 leukemic cells, cells treated with compound for 24 hrs were stained with anti-Mac1-PB, anti-Ly- 6G(Gr1)-PE, anti-CD115-APC and anti-F4/80-Pe-Cy7. Samples were stained with 2%FBS RPMI with diluted antibodies for 20 min in the dark, washed and analyzed with LSRII or LSR Fortessa (BD Biosciences) and data was graphed by using FlowJoTM version 10.4. For apoptosis assessment, MOLM-13 cells treated with compound for 48 hrs or MLL-AF9 cells treated with compound for 24 hrs, were washed with cold PBS and incubated with anti- Annexin V-APC (BD Biosciences) in the Annexin-V binding buffer (10 mM HEPES, pH 7.4, 140 mM NaCl, 4 mM KCl, 0.75 mM MgCl 2 , 1 mM CaCl 2 ) together with DAPI in the reaction volume of 100 mL for 15 minutes as recommended by the manufacturer. [00349] Flow cytometry for measuring degradation: 4.5 x 10 4 HEK293T GFP-POI (CK1α, GSPT1, IKZF1, IKZF2) cells were seeded in a U-bottom 96-well plate in 200 μL of media and allowed to adhere for 2 h at 37 °C and 5% CO 2 . Cells were treated with 2 μL of a one-hundred-fold stock solution of compound in DMSO and incubated at 37 °C and 5% CO2 for 24 h. The media was aspirated and 100 μL of a 50/500.5% trypsin-EDTA/PBS solution were added to each well and incubated at 37 °C for 4 min. Media (100 μL) and propidium iodide/PBS (0.5 mg/mL, 4 μL) were added to each well and cells were resuspended via pipetting prior to analysis with a BD LSR Fortessa flow cytometer at the Harvard University Bauer Core Facility. Raw FITC sample averages were exported to Excel and normalized to the DMSO treated average representing 100% fluorescence. These values were graphed using GraphPad Prism 7.0 and the nonlinear regression curve fit model was used to generate best- fit curves, error bars, D max and DC 50 values. [00350] Cell Cycle Analysis: For cell cycle analysis, MOLM-13 cells treated with 1μM DEG-35 or DEG-77 were washed with PBS and fixed in ice-cold 70% ethanol for few hours. Fixed cells were pelleted and washed twice with PBS and incubated in PBS containing 3.8 mM Sodium Citrate, propidium iodide (50μg/ml) and RNase A (100μg/ml) for 30 min at 4 o C in the dark. Nuclei were then analyzed by running at low flow rate in LSRII for 10,000 events. [00351] Wright-Giemsa Staining: 50,000-100,000 MOLM-13 cells were cytospun onto poly-lysine coated glass slides. Slides were then processed for Wright-Giemsa Staining by dipping slides into fixative, Solution A and Solution B of the Three-Step Stain Kit (Richard- Allan Scientific) for 30 seconds each. Dried slides were mounted with cover slides. [00352] Colony forming Unit Assay: Colony Assay for human CD34+ HSPCs, normal bone marrow cells or AML patient cells were performed by plating 5000 cells on methylcellulose (MethoCult H4434 Classic-Stem Cell Technologies). Colonies were assessed and counted 10 to 14 days after seeding. 500 sorted murine LSK cells from Wt or Crbn I391V mice and 1000 bone marrow cells from MLL-AF9 Wt or Crbn I391V mice were plated on MethoCult M3434 and counted 5-10 days after plating. [00353] Mass spectrometry data analysis: Analysis was performed in Thermo Scientific Proteome Discoverer version 2.4.1.15. The raw data was searched against a protein sequence database including all entries from the Human Uniprot database (August 19, 2016; 20,156 entries, SwissProt) and a list of common contaminant proteins. Search parameters included a 10-ppm precursor ion tolerance and 0.02 Da (HCD) or 0.6 Da (CID) fragment ion tolerance, full tryptic protease specificity with up to two missed cleavages, a static modification of TMTpro 16-plex at lysine residues and N-termini (+304.2071 Da), static carboxyamidomethylation of cysteine residues (+57.0214 Da), and variable oxidation on methionine residues (+15.9949 Da). Peptide spectral matches (PSMs) were filtered for a false discovery rate (FDR) of 1% using Percolator. TMT reporter ions were quantified using the Reporter Ions Quantifier node and the total intensity was normalized for each TMT channel. Quantified proteins were required to have at least three unique peptides and four separate PSMs. All TMT-based experiments were performed with four replicates. [00354] In cellulo co-immunoprecipitation: HEK-293T cells stably transfected with Flag- tagged CRBN were plated in a 10 cm dish and allowed to grow to full confluency. Cells were treated with 10 μM MG132 and incubated for 1 h at 37 oC. The cells were then treated with either 10 μM DEG35 or DMSO and incubated for 3 h at 37 oC. Cells were washed with PBS (2 × 10 mL) and Cell Lysis Buffer (CST, 400 μL) containing MG132 (10 μM) and 1× protease inhibitors was added to each plate. The cells were incubated for 5 min on ice and then harvested by scraping. Lysate was incubated on ice for 5 min and then cleared by centrifugation (21,130 × g) for 10 min at 4 o C. Solubilized protein concentration was determined by BCA assay and adjusted to 1 mg/mL in lysis buffer. Adjusted lysate (200 μL) was added to anti-Flag M2 magnetic beads (30 μL) previously washed with TBS (3 × 300 μL) and incubated for 1 h at 4 o C. The supernatant was removed, and the beads were washed with lysis buffer (3 × 300 μL). 1× Laemmli sample buffer (50 μL) was added to the beads and boiled for 5 min at 95 o C. Results were analyzed by Western blot. [00355] HTR-FRET: PerkinElmer’s Cereblon binding assay kit was used. A series of 4- fold serial dilutions of lenalidomide, DEG-35, and DEG-77 in 4% DMSO/dilution buffer were prepared fresh for each experiment. Compound (5 μL) was added to each well of a 384- well microplate. A solution of CRBN/1× PROTAC binding buffer (5 μL) and a solution of premixed thalidomide red glutathione-europium cryptate antibody/1× PROTAC binding buffer (10 μL) were added to each well. The plate was sealed with TopSeal-A PLUS and incubated at 25 o C for 3 h. The seal was removed, and the plate was analyzed. [00356] In vivo drug administration in MLL-AF9 and PDX mouse model: A total of 250,000 of MLL-AF9 BM secondary mouse leukemia cells were injected retroorbitally into 6-8 weeks-old female C57BL/6 recipient mice that has been sublethally irradiated at 450 cGy. For AML PDX model, 1 million PDX cells were transplanted by intravenous injection into 8-10 weeks old female NSG mice that had been sublethally irradiated at 200 rads 24 hr before transplant. For both models, 3 days after transplant, DEG-35 or vehicle was administrated by intraperitoneal injections at 50 mg/kg in DMSO in 50 ul volume for in vivo long-term studies. DEG-77 was treated at 223 mg/kg in DMSO in 50 ul volume. Mice weight was monitored every day to check for toxicity. Mice were sacrificed when moribund, and organ weights were measured for disease burden. Spleen and bone marrow cells were isolated and processed for western blot analysis. All animal studies were performed on animal protocols approved by the Institutional Animal Care and Use Committee (IACUC) at Memorial Sloan Kettering Cancer Center. In the case for pharmacodynamic experiments, DEG-35 or DEG-77 were administrated 2 weeks post-transplant of MLL-AF9 BM secondary mouse leukemia cells in C57BL/6 recipient mice. DEG-35, DEG-77 or DMSO was administrated by intraperitoneal injections at 50 mg/kg or 223 mg/kg. After single dose treatment of DEG-35 or DEG-77, mice were sacrificed at either 24 hr, 48 hr or 72 hr later and, spleen and bone marrow cells were processed for analysis. For Pharmacokinetics experiments, a single dose of DEG-35 at 5 mg/kg or 50 mg/kg and DEG-77 at 5 mg/kg in DMSO were administered intraperitoneally into male CD1 mice. Plasma was extracted from each mouse after indicated time and DEG-35 in plasma was measured using HPLC. For examining the toxicity of DEG-77 in the hematopoietic system of Crbn I391V mice, four rounds of DMSO or 223mg/kg DEG-77 was treated in 8-12 weeks old female Crbn I391V mice. Mice were injected once a week and were sacrificed 4 weeks later for blood analysis using the Element HT5 Hematology Analyzer (HESKA) and analysis of the hematopoietic cells by flow cytometry. [00357] Reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR) : A2780 or TOV-21G cells were seeded in a 6-well plate at a density of 2.0 × 10 6 cells/well in 2 mL media and allowed to adhere for 2 h at 37 °C and 5% CO 2 . Cells were treated with 2 μL of a one-thousand-fold stock solution of D77 in DMSO to a final concentration of 1 μM or DMSO and incubated for 24 h at 37°C and 5% CO2. Media was harvested into a microcentrifuge tube and centrifuged (21,130 g) for 3 min. Media was aspirated. Cells were trypsinized with 750 μL of 0.25% trypsin for 3 min. Trypsin was quenched with 750 μL of media. Media was harvested into the microcentrifuge tubes and centrifuged (21,130 g) for 3 min. Media was aspirated and cells were washed with PBS (2 × 1 mL). The Monarch Total RNA Miniprep Kit was used to isolate and purify RNA from the cells. Resulting RNA extracts were diluted to 56.8 ng/μL and the NEB Luna Universal One-Step RT-qPCR Kit was used to prepare the samples for RT-qPCR. 20 μL of combined RNA/enzyme/primer mixes were aliquoted into a 96-well plate and centrifuged (1000 × g) for 1 min at room temperature. Samples were run in biological triplicate. RT-qPCR was performed in a BioRad iQ5 Real- Time PCR Detection System and results were exported to Microsoft Excel for analysis following the ΔΔCt model (Livak K. J. and Schmittgen T. D.). Processed gene expression values were then graphed using GraphPad Prism 7.0. [00358] Quantitative global proteomics: MOLM-13 cells were seeded at 2.3 × 10 6 cells in 1 mL of RPMI. Cells were treated with 50 nM DEG-77 or DMSO (5 replicates each) and incubated at 37 ºC for 2 h. Cells were harvested and pelleted by centrifugation (500 × g, 2 min) at 24 ºC and washed with PBS (2 × 1 mL). The washed cells were suspended in 5% SDS/50 mM TEAB (110 µL) containing protease inhibitor cocktail and sonicated on ice using a probe tip sonicator (11% amplitude, 5 s on, 3 s off, 30 s total). The sonicated lysates were cleared by centrifugation (13,000 × g, 10 min) at 4 ºC. The soluble protein concentration was determined by BCA assay and adjusted to 1.1 mg/mL with lysis buffer. Lysates (100 µL) were reduced with dithithreitol (11 µL, 50 mM, final concentration 5 mM) at 24 ºC for 30 min and subsequently alkylated with iodoacetamide (9 µL, 200 mM, final concentration 15 mM) at 24 ºC for 30 min in the dark. The samples were acidified with 12% phosphoric acid (12 µL) and diluted with S-trap buffer (90% methanol, 100 mM TEAB, pH 7.55, 720 µL). The diluted samples were transferred to an S-trap micro attached to a vacuum manifold and the supernatant was drained. The samples were washed with S-trap buffer (3 × 800 µL) and dried by centrifugation (4000 × g, 1 min) at 24 ºC. Sequencing-grade trypsin (11 µg) in 50 mM TEAB (125 µL) was added to each S-trap and the samples were incSubated at 37 ºC for 16 h. 50 mM TEAB (80 µL) was added to each sample and incubated at 24 ºC for 30 min. The S-traps were centrifuged (4000 × g, 1 min) at 24 ºC and the digested peptides were sequentially eluted with 0.2% formic acid/water (80 µL) and 50% acetonitrile/water (80 µL). The combined eluents were combined and dried by vacufuge. The dried peptides were resuspended in water (25 µL) and TMT 10-plex reagent (10 µL) was added and incubated at 24 ºC for 1 h. To quench excess TMT reagent, 5% hydroxylamine (1.2 µL) was added and incubated at 24 ºC for 15 min. The labeled samples were combined and dried by vacufuge. The dried sample was resuspended in 0.1% TFA/water (300 µL), loaded on to a Pierce peptide desalting spin column (catalog #89851), desalted according to manufacturer instructions, and dried by vacufuge. [00359] The desalted peptides were resuspended in 0.1% TFA/water (450 µL) and fractionated by high pH reverse-phase HPLC. The sample was injected onto an Aeris 3.6 µm Peptide XB-C18 column with mobile phase A containing 10 mM NH4HCO3 in 5% acetonitrile/water, pH 8.0 and mobile phase B containing 10 mM NH 4 HCO 3 in 90% acetonitrile water, pH 8.0. The sample was run through the column over 60 min with a flow rate of 1 mL/min with the following gradient: 1% B for 4 min, 35% B in 50 min, 60% B in 4 min, 80% B in 2 min. 0.7 mL fractions were collected between 4 min and 60 min. The fractions were dried, resuspended in 0.1% TFA/water (50 µL) and combined non- continuously into 20 samples and dried by vacufuge. The samples were then resuspended in 0.1% TFA/water (40 µL) for injection on to the mass spectrometer. [00360] Proteomics mass spectrometry acquisition procedures for protein level quantification: The LC-MS/MS experiment was performed on an Orbitrap Eclipse Tribrid Mass Spectrometer coupled with a Vanquish Neo HPLC system (Thermo scientific) at the Harvard Center for Mass Spectrometry. The TMT labelled peptides were first trapped on a trapping cartridge (300 µm x 5 mm PepMap™ Neo C18 Trap Cartridge, Thermo scientific) prior to separation on a silica-chip-based micropillar column (µPAC, C18 pillar surface, 50 cm bed, Thermo scientific). The column oven temperature was maintained at 35 °C. Peptides were eluted using a multi-step gradient at a flow rate of 300 nL/min over 180 min. The mobile phase A and weak wash liquid was water with 0.1% formic acid (FA), and mobile phase B was acetonitrile with 0.1% FA, and strong wash liquid was 80% acetonitrile with 0.1% FA. The mobile phase gradient consisted of a linear 125 min gradient from 2% to 20% mobile phase B, followed by a 24 min increase to 35% B, a further 10-min increase to 95% B, a 20 min plateau phase at 95% B. The autosampler temperature was 7 ºC. The column “Fast equilibration” was enabled. The Orbitrap Eclipse MS was operated in DDA mode with 3 s cycle time. The electrospray ionization was in positive mode with voltage of 2.1 kV and the capillary temperature at 275 ºC. Dynamic exclusion was enabled with a mass tolerance of 10 ppm and exclusion duration of 60 s. Full scan was performed in the range of 400-1,600 m/z at a resolution of 120,000, RF lens 30%, normalized AGC target 200% and maximum injection time set to auto. Precursors were isolated in a window of 0.7 m/z and charge states from two to six. Fragmentation was performed by HCD using normalized collision energy (NCE) of 38% at the resolution of 50,000. The normalized AGC target was set to 250%, and a maximum ion injection time set to 200 ms.
