[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 62 / 135,125, filed March 18, 2015, entitled "Compounds and Methods for the Enhanced Degradation of Targeted Proteins and Other Polypeptides by an E3 Ubquitin Ligase," which is incorporated herein by reference in its entirety.

[0002] STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH This invention was made with government support under Grant No. AI084140 awarded by the National Institutes of Health. The government has certain rights in this invention.

[0003] 1. Field of Discovery The present invention relates to bifunctional compounds useful as modulators of targeted ubiquitination. In particular, the present invention relates to compounds comprising a VHL ligand at one end that binds to the VHL E3 ubiquitin ligase and a moiety that binds to a target protein at the other end, such that degradation of the target protein / polypeptide is effected. The present invention demonstrates a wide range of pharmacological activities associated with the compounds of the present invention, consistent with the degradation / inhibition of the target polypeptide. [Background technology]

[0004] 2. Background information E3 ubiquitin ligases (of which over 600 are known in humans) confer substrate specificity for ubiquitination, making them more attractive therapeutic targets than general proteasome inhibitors due to their specificity for specific protein substrates. Development of ligands for E3 ligases has proven challenging, in part due to the fact that they necessarily disrupt protein-protein interactions; however, recent developments have provided specific ligands that bind to these ligases. Protein-protein interactions are notoriously difficult to target using small molecules due to the large surface areas involved and the shallow grooves or flat interfaces involved. Conversely, most small molecule drugs bind to enzymes or receptors in tight, well-defined pockets. Following the discovery of the first small molecule E3 ligase inhibitor, nutlin, additional compounds targeting inhibitors of apoptosis proteins (IAPs), SCFMet30 and SCFCdc4, were reported, but the field remains evolving.

[0005] One E3 ligase with exciting therapeutic potential is the von Hippel-Lindau (VHL) tumor suppressor, which is the substrate-recognition subunit of the E3 ligase complex VCB and is also composed of elongins B and C, Cul2, and Rbx1. The primary substrate of VHL is hypoxia-inducible factor 1α (HIF-1α), a transcription factor that upregulates genes such as the proangiogenic growth factor VEGF and the erythropoiesis-inducing cytokine erythropoietin in response to low oxygen levels. Although HIF-1α is constitutively expressed, its intracellular levels are maintained very low under normoxic conditions by its hydroxylation by prolyl hydroxylase domain (PHD) proteins and subsequent VHL-mediated ubiquitination (Figure 1).

[0006] The crystal structure of VHL with a ligand was obtained, confirming that small molecule compounds can mimic the binding mode of the transcription factor HIF-1α, a major substrate of VHL. Using rational design, the first small molecule ligand of von Hippel-Lindau (VHL), the substrate recognition subunit of the E3 ligase VCB, an important target in cancer, chronic anemia, and ischemia, was generated.

[0007] However, there remains a continuing need in the art for small molecule therapeutics that are effective across disease indications. Provided herein are tools for recruiting proteins to E3 ligases for ubiquitination and degradation with the goal of providing therapies based on targeted protein degradation. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0020] Detailed Description The following is a detailed description provided to assist those skilled in the art in practicing the present invention. Those skilled in the art can make modifications and variations to the embodiments described herein without departing from the spirit or scope of the present disclosure. All publications, patent applications, patents, drawings, and other references mentioned herein, including WO 2013 / 106643 and US 2014-0356322, are expressly incorporated by reference in their entirety.

[0021] Described herein are compositions that bind to E3 ubiquitin ligase protein complexes. In particular, compositions that bind to von Hippel-Lindau (VHL), the substrate recognition subunit of the E3 ligase complex VCB, are described. Additionally, the present specification provides bifunctional compounds containing the same and related methods of use for ubiquitination and / or degradation of selected target proteins. The present specification also provides libraries of the compounds described herein.

[0022] The following terms are used to describe the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and one of ordinary skill in the art will apply the term in context to its use in describing the invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] When a range of values ​​is recited, it is understood that each intervening value between the upper and lower limit of that range and any other stated or intervening value within that stated range, to the tenth of the unit of the lower limit, is encompassed within the invention, unless the context clearly dictates otherwise (e.g., in the case of a group containing a number of carbon atoms, each number of carbon atoms within the range is recited). The upper and lower limits of these subranges may independently be included in the subranges and are also encompassed within the invention, provided that any limit with respect to the stated range is specifically excluded. When the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.

[0025] As used in this specification and the appended claims, the articles "a" and "an" are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article, unless the context clearly dictates otherwise. For example, "an element" means one element or more than one element.

[0026] The term "and / or," as used in this specification and the appended claims, should be understood to mean "one or both" of the elements so coordinated, i.e., elements that are present conjunctively in some cases and disjunctively in other cases. Multiple elements listed with "and / or" should be construed in the same manner, i.e., "one or more" of the elements so coordinated. Other elements, related or unrelated to the elements specifically identified by the "and / or" clause, may be present. Thus, as a non-limiting example, a reference to "A and / or B," when used in combination with open-ended terms such as "comprising," can mean, in one embodiment, A only (optionally including elements other than B), in another embodiment, B only (optionally including elements other than A), or in yet another embodiment, both A and B (optionally including other elements).

[0027] As used herein and in the appended claims, "or" should be understood to have the same meaning as "and / or" as defined above. For example, when separating items in a list, "or" or "and / or" should be interpreted as being inclusive, i.e., including not only at least one, but also two or more of the elements of a number or list and, optionally, additional unlisted items. Only terms clearly indicating the contrary, such as "only one" or "exactly one," or "consisting of" as used in the appended claims, shall imply the inclusion of exactly one element of a number or list. In general, the term "or" as used herein, when preceded by terms indicating exclusivity such as "either," "one," "only one," or "exactly one," shall be interpreted as indicating only exclusive alternatives (i.e., "one or the other, but not both").

[0028] In the appended claims and the above specification, all transitional phrases such as "comprising," "including," "holding," "having," "containing," "comprising," and the like, are to be understood to mean open-ended, i.e., "including, but not limited to." Only the transitional phrases "consisting of" and "consisting essentially of" shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.

[0029] As used herein and in the appended claims, the phrase "at least one," in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more elements in the list of elements, but not necessarily including at least one of all elements specifically listed in the list of elements, and not excluding any combination of elements in the list of elements. This definition also contemplates that elements other than those specifically identified in the list of elements to which the phrase "at least one" refers, whether related or unrelated to those specifically identified elements, may be present. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B," or, equivalently, "at least one of A and / or B") can mean, in one embodiment, at least one A that optionally includes two or more As, and no Bs (optionally including elements other than B); in another embodiment, at least one B that optionally includes two or more Bs, and no As (optionally including elements other than A); in yet another embodiment, at least one A that optionally includes two or more As, and at least one B that optionally includes two or more Bs (optionally including other elements);

[0030] It should also be understood that, in particular methods described herein that include more than one step or action, the order of the method steps or actions is not necessarily limited to the order in which the method steps or actions are described, unless the context dictates otherwise.

[0031] The terms "co-administration" and "co-administering," or "combination therapy," refer to both simultaneous administration (administration of two or more therapeutic agents at the same time) and staggered administration (administration of one or more therapeutic agents at a time different from the time of administration of one or more additional therapeutic agents), so long as the therapeutic agents are present in the patient at some level, preferably in effective amounts, at the same time. In certain preferred aspects, one or more of the present compounds described herein are co-administered in combination with at least one additional bioactive agent, particularly including anti-cancer agents. In particularly preferred aspects, co-administration of the compounds results in synergistic activity and / or therapy, including anti-cancer activity.

[0032] As used herein, the term "compound," unless otherwise indicated, refers to any specific compound disclosed herein and includes, within the context, tautomers, positional isomers, geometric isomers, and, where appropriate, stereoisomers, including optical isomers (enantiomers) and other stereoisomers (diastereomers), thereof, as well as, where appropriate, pharmaceutically acceptable salts and derivatives (including prodrug forms) thereof. Within the context of use, the term compound generally refers to a single compound, but may also include other compounds, such as stereoisomers, positional isomers, and / or optical isomers (including racemic mixtures), as well as specific enantiomers or enantiomerically enriched mixtures of the disclosed compounds. Within the context, the term also refers to prodrug forms of compounds modified to facilitate administration and delivery of the compound to the active site. It should be noted that in describing the present compounds, numerous substituents and variables associated therewith are specifically described. Those skilled in the art will understand that the molecules described herein are stable compounds, as generally described below. Bonding When TIFF2025128169000002.tif6128 is depicted, both double and single bonds are represented within the context of the depicted compound.

[0033] The term "patient" or "subject" is used throughout this specification to describe an animal, preferably a human or domestic animal, to which treatment, including prophylactic treatment, with the compositions of the present invention is administered. With respect to the treatment of an infection, condition, or disease state specific to a particular animal, such as a human patient, the term patient refers to the particular animal, including domestic animals such as dogs or cats, or livestock such as horses, cows, sheep, etc. Generally, in the present invention, the term patient refers to a human patient, unless otherwise stated or implied from the context of the use of the term.

[0034] The term "effective" is used to describe an amount of a compound, composition, or ingredient that produces a desired result when used in the context of its intended use. The term effective encompasses all other terms relating to effective amount or effective concentration alternatively described or used in this application.

[0035] The terms "VCB E3 ubiquitin ligase," "von Hippel-Lindau (or VHL) E3 ubiquitin ligase," "VHL," or "ubiquitin ligase" are generally used interchangeably unless the context indicates otherwise, e.g., to describe the target enzyme binding site of the ubiquitin ligase moiety described herein in the bifunctional (chimeric) compounds described herein. VCB E3s are proteins that, in combination with an E2 ubiquitin-conjugating enzyme, cause the attachment of ubiquitin to lysines on target proteins, and the E3 ubiquitin ligase targets specific protein substrates for degradation by the proteasome. Thus, the E3 ubiquitin ligase, alone or in complex with an E2 ubiquitin-conjugating enzyme, is responsible for the transfer of ubiquitin to the targeted protein. Generally, ubiquitin ligases are involved in polyubiquitination, where a second ubiquitin binds to the first, a third ubiquitin binds to the second, and so on. Polyubiquitination marks proteins for degradation by the proteasome. However, some ubiquitination events are limited to monoubiquitination, in which the ubiquitin ligase attaches only one ubiquitin to the substrate molecule. Monoubiquitinated proteins are not targeted to the proteasome for degradation, but instead can alter their cellular location or function, for example, by binding to other proteins with ubiquitin-binding domains. To further complicate matters, different lysines on ubiquitin can be targeted by E3s to create chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to create polyubiquitin, which is recognized by the proteasome.

[0036] As used herein, a moiety that binds to an E3 ubiquitin ligase or a component thereof, such as VHL, is referred to as a ubiquitin ligase binding moiety or "ULM."

[0037] The term "protein targeting moiety" or PTM is used to describe a small molecule that binds to a target protein or polypeptide of interest or other proteins or polypeptides and positions / places the protein or polypeptide in proximity to ubiquitin ligase so that degradation of the protein or polypeptide by ubiquitin ligase can occur. Non-limiting examples of small molecule target protein binding molecules include, among others, Hsp90 inhibitors, kinase inhibitors, MDM2 inhibitors, compounds targeting human BET bromodomain-containing proteins, HDAC inhibitors, human lysine methyltransferase inhibitors, angiogenesis inhibitors, immunosuppressive compounds, and compounds targeting aryl hydrocarbon receptors (AHR). The compositions described below exemplify some members of these and other types of small molecule target proteins. By binding a ULM to a protein target binding moiety ("PTM"), the target protein is ubiquitinated and / or degraded by the proteasome (see Figure 1).

[0038] As noted above, the present specification relates to the surprising and unexpected discovery that an E3 ubiquitin ligase protein will ubiquitinate a target protein when the E3 ubiquitin ligase protein and the target protein are brought into close proximity by a bifunctional PROTAC compound that binds to the E3 ubiquitin ligase protein or a component thereof and the target protein. Accordingly, the present specification provides compounds that bind to E3 ubiquitin ligase proteins, and bifunctional PROTAC compounds comprising the same.

[0039] Compounds and Compositions Compounds useful for regulating protein activity are described herein. The compounds include a ubiquitin pathway protein binding moiety described herein (preferably for an E3 ubiquitin ligase, either alone or in complex with an E2 ubiquitin-conjugating enzyme that is responsible for the transfer of ubiquitin to the targeted protein). Preferably, the E3 ubiquitin ligase binding moiety is a small molecule (i.e., not peptide-based). In certain aspects and embodiments, the ubiquitin pathway protein binding moiety is chemically linked to the protein targeting moiety by bond or through a chemical linker, wherein the ubiquitin ligase binding moiety recognizes the ubiquitin ligase, the targeting moiety recognizes the target protein, and the ubiquitin ligase protein binding moiety is bound to the targeting moiety.

[0040] In one aspect, the description provides ubiquitin ligase-binding compounds (ULMs) capable of binding to an E3 ubiquitin ligase, e.g., VHL, as further described below. In certain embodiments, the ULMs bind to VHL.

[0041] In a further aspect, the invention relates to compounds of the structure L-ULM, where L is a linker group and ULM is a ubiquitin ligase binding moiety. In certain embodiments, ULM is attached to a PTM directly or by a chemical linker.

[0042] In another aspect, the description provides compounds of the general structure ULM-L-PTM comprising a PTM group, where ULM is an E3 ubiquitin ligase-binding moiety, e.g., a VHL-binding moiety, and the PTM is a chemical moiety (protein targeting moiety) that binds to a target protein or polypeptide, which is ubiquitinated by a ubiquitin ligase and is chemically linked to the ULM group directly or through a linker moiety, L, which can be a bond or a chemical linker. Alternatively, in certain embodiments, the PTM is a ULM' group, which is also an E3 ubiquitin ligase-binding moiety, or a pharmaceutically acceptable salt, enantiomer, stereoisomer, solvate, or polymorph thereof, and the ULM' group can be the same as or different from the ULM group and is linked to the ULM group directly or through a linker moiety. In certain embodiments, at least one of the ULM and ULM' (if present) is linked to the PTM, PTM', or a combination thereof, directly (a bond) or by a chemical linker.

[0043] In certain aspects of the invention where the PTM is a ULM' group, the compound is like a dimeric compound where both ends of the compound contain a ubiquitin ligase binding moiety as described elsewhere herein.

[0044] The ULM and PTM groups can be covalently linked to the linker group through any group that is suitable and stable to the linker chemistry, although in certain embodiments, as described in further detail below, the linkers can be independently covalently linked to the ULM and PTM groups through an amide, ester, thioester, keto group, carbamate (urethane), carbon, or ether, any of which groups can be inserted anywhere on the ULM and PTM groups to achieve maximal coupling between the ULM group on the ubiquitin ligase and the PTM group on the target protein to be degraded. (Note that in certain aspects where the PTM group is a ULM group, the target protein to be degraded can be the ubiquitin ligase itself.) In certain aspects, the linker can be linked to an optionally substituted alkyl, alkylene, alkene, or alkyne group, an aryl group, or a heterocyclic group on the ULM and / or PTM group.

[0045] In a further aspect, the description provides a library of compounds, the library including two or more compounds, each of which is a ULM as described herein.

[0046] In a further aspect, the description provides a library of compounds of formula AB, where A is a ubiquitin pathway protein binding moiety or ULM (preferably an E3 ubiquitin ligase moiety as disclosed elsewhere herein); B is a protein-binding moiety or PTM of a molecular library; A is linked to B (preferably through a linker moiety); and the ubiquitin pathway protein binding moiety recognizes a ubiquitin pathway protein, particularly an E3 ubiquitin ligase. In certain embodiments, the library comprises a ubiquitination recognition moiety (a ubiquitin pathway protein binding moiety as disclosed elsewhere herein) specific for VHL as an E3 ubiquitin ligase, along with a random target protein binding element (e.g., a compound library). Thus, the target protein is not determined in advance, and the method can be used to determine the activity of a putative protein-binding element as a target for degradation by a ubiquitin ligase, and its pharmacological value.

[0047] In any aspect or embodiment described herein, ULM, and, if present, ULM′, is each independently a group of the following chemical structure or a pharmaceutically acceptable salt, stereoisomer, solvate, or polymorph thereof: TIFF2025128169000003.tif36128In formula, R 1' is an optionally substituted C1-C6 alkyl group, an optionally substituted -(CH2) n OH, optionally substituted -(CH2) n SH, optionally substituted (CH2) n an optionally substituted —O—(C1-C6) alkyl group, including an epoxide moiety WCOCW, where each W is independently H or a C1-C3 alkyl group (CH2);

[0082] The term "independently" is used herein to indicate that independently applied variables vary independently from application to application.

[0083] The term "alkyl" refers, in context, to an optionally substituted straight-chain, branched-chain, or cyclic fully saturated hydrocarbon or alkyl group, preferably C1-C 10, more preferably C1-C6 or C1-C3 alkyl groups. Examples of alkyl groups include methyl, ethyl, n-butyl, sec-butyl, n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyl, isopropyl, 2-methylpropyl, cyclopropyl, cyclopropylmethyl, cyclobutyl, cyclopentyl, cyclopentylethyl, cyclohexylethyl, and cyclohexyl, among others. In certain embodiments, the alkyl groups are end-capped with a halogen group (At, Br, Cl, F, or I). In certain preferred embodiments, the compounds of the invention can be used to covalently attach to dehalogenase enzymes. Generally, these compounds contain a side chain (often linked through a polyethylene glycol group) distal to an alkyl group bearing a halogen substituent (often chlorine or bromine) that allows the compound containing the moiety to be covalently attached to a protein.

[0084] The term "alkenyl" refers to a straight, branched, or cyclic C-C alkyl group containing at least one C=C bond. 10 It means a (preferably C2 to C6) hydrocarbon group.

[0085] The term "alkynyl" refers to a straight, branched, or cyclic C-C alkyl group containing at least one C≡C bond. 10 It means a (preferably C2 to C6) hydrocarbon group.

[0086] When the term "alkylene" is used, it refers to an optionally substituted -(CH) n- group (n is generally an integer from 0 to 6). When substituted, the alkylene group is preferably substituted on one or more methylene groups with a C1-C6 alkyl group (including a cyclopropyl or t-butyl group), but may also be substituted with one or more halo groups, preferably 1 to 3 halo groups, or with one or two hydroxyl groups, an O-(C1-C6 alkyl) group, or an amino acid side chain as otherwise disclosed herein. In certain embodiments, the alkylene group may be substituted with a urethane or alkoxy group (or other group), which is further substituted with a polyethylene glycol chain (of 1 to 10, preferably 1 to 6, often 1 to 4 ethylene glycol units), which in turn is substituted with an alkyl chain substituted with one halogen, preferably a chlorine, group (preferably, but not limited to, at the distal end of the polyethylene glycol chain). In still other embodiments, the alkylene (often methylene) group may be substituted with an amino acid side chain group, such as the side chain group of a natural or unnatural amino acid, such as alanine, β-alanine, arginine, asparagine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, phenylalanine, histidine, isoleucine, lysine, leucine, methionine, proline, serine, threonine, valine, tryptophan, or tyrosine.

[0087] The term "unsubstituted" is intended to mean substituted only with hydrogen atoms. A range of carbon atoms that includes C0 means that the carbon is absent and replaced with H. Thus, a range of carbon atoms that is C0-C6 includes 1, 2, 3, 4, 5, and 6 carbon atoms, with C0 being replaced with H.

[0088] The terms "substituted" or "optionally substituted" are intended to refer independently to one or more substituents (independently up to 5 substituents, preferably up to 3 substituents, and often 1 or 2 substituents on a moiety in a compound of the invention, which may themselves include substituents which may be further substituted) at any carbon (or nitrogen) position on the molecule within the context (i.e., when more than one substituent occurs, each substituent is independent of the other substituents), including hydroxyl, thiol, carboxyl, cyano (C≡N), nitro (NO), halogen (preferably 1, 2, or 3 halogens, especially on an alkyl, especially a methyl group, e.g., trifluoromethyl), alkyl groups (preferably C1-C 10, more preferably C1-C6), aryl (especially phenyl and substituted phenyl, for example benzyl or benzoyl), alkoxy groups (preferably C1-C6 alkyl, or aryl, including phenyl and substituted phenyl), thioether (C1-C6 alkyl or aryl), acyl (preferably C1-C6 acyl), ester or thioester (preferably C1-C6 alkyl or aryl), including alkylene esters (in alkylene esters, the bond is on the alkylene group rather than the ester functionality, which is preferably substituted with a C1-C6 alkyl or aryl group), preferably C1-C6 alkyl or aryl, halogen (preferably F or Cl), amine (including 5- or 6-membered cyclic alkylene amines). and C1-C6 alkylamine or C1-C6 dialkylamine, wherein the alkyl group is optionally substituted with one or two hydroxyl groups; an optionally substituted -N(C0-C6 alkyl)C(O)(O-C1-C6 alkyl) group (which may be substituted with a polyethylene glycol chain to which is further attached an alkyl group containing one halogen, preferably chlorine, substituent); hydrazine; an amide preferably substituted with one or two C1-C6 alkyl groups (including a carboxamide optionally substituted with one or two C1-C6 alkyl groups); an alkanol (preferably C1-C6 alkyl or aryl); or an alkanoic acid (preferably C1-C6 alkyl or aryl).

In certain embodiments, the alkylene group (often a methylene group) is substituted with one or two optionally substituted C1-C6 alkyl groups, preferably C1-C4 alkyl groups, most often methyl or O-methyl groups, or an amino acid side chain as described elsewhere herein. In the present invention, moieties in a molecule may be substituted with up to five substituents, preferably up to three substituents. Most often, in the present invention, a substituted moiety is substituted with one or two substituents.

[0125] Exemplary PTMs In other aspects of the invention, the PTM group is a group that binds to a target protein. Targets for the PTM group are numerous and selected from proteins expressed in cells such that at least a portion of the sequence is found in the cell and capable of binding to a PTM. The term "protein" includes oligopeptide and polypeptide sequences of sufficient length to be capable of binding to the PTM groups of the invention. Any protein in a eukaryotic or microbial system, including viruses, bacteria, or fungi, as described elsewhere herein, is a target for ubiquitination mediated by the compounds of the invention. Preferably, the target protein is a eukaryotic protein. In certain aspects, the protein-binding moiety is a haloalkane (preferably a C1-C10 alkyl group substituted with at least one halo group, preferably at the distal end of the alkyl group (i.e., away from the linker or ULM group)), which can be covalently attached to a dehalogenase enzyme in a patient or subject or in a diagnostic assay.

[0126] PTM groups of the present invention include, for example, any moiety that specifically binds to a protein (binds to a target protein), including, among others, the following non-limiting examples of small molecule target protein moieties: Hsp90 inhibitors, kinase inhibitors, MDM2 inhibitors, compounds targeting human BET bromodomain-containing proteins, HDAC inhibitors, human lysine methyltransferase inhibitors, angiogenesis inhibitors, immunosuppressive compounds, and compounds targeting the aryl hydrocarbon receptor (AHR). The compositions described below exemplify several members of these nine classes of small molecule target protein binding moieties. Such small molecule target protein binding moieties also include pharmaceutically acceptable salts, enantiomers, solvates, and polymorphs of these compositions, as well as other small molecules that can target a protein of interest. These binding moieties are preferably linked to the ubiquitin ligase binding moiety via a linker so that the target protein (to which the protein targeting moiety is bound) is in close proximity to the ubiquitin ligase for ubiquitination and degradation.

[0127] Any protein that can be attached to a protein targeting moiety or PTM group and acted upon or degraded by a ubiquitin ligase is a target protein of the present invention. In general, target proteins include, for example, proteins involved in catalytic activity, aromatase activity, motility activity, helicase activity, metabolic processes (anabolic and catabolic), antioxidant activity, proteolysis, biosynthesis, kinase activity, oxidoreductase activity, transferase activity, hydrolase activity, lyase activity, isomerase activity, ligase activity, enzyme regulator activity, signal transducer activity, structural molecule activity, binding activity (proteins, lipids, carbohydrates), receptor activity, cell motility, membrane fusion, cell-to-cell communication, regulation of biological processes, development, cell differentiation, stimulation, and the like. These proteins may include structural proteins, receptors, enzymes, cell surface proteins, proteins involved in the integrated function of cells, including proteins involved in response to stimuli, behavioral proteins, cell adhesion proteins, proteins involved in cell death, proteins involved in transport (including protein transporter activity, nuclear transport, ion transporter activity, channel transporter activity, carrier activity, permease activity, secretion activity, electron transporter activity, virulence, chaperone regulator activity, nucleic acid binding activity, transcription regulator activity, extracellular organization and biogenesis activity, translation regulator activity), etc. Proteins of interest may include proteins from eukaryotes and prokaryotes, including humans, other animals, including domestic animals, as targets for drug therapy, microorganisms for the identification of targets for antibiotics and other antimicrobial agents, and plants, as well as viruses, among others.

Haloalkyl groups are generally straight-chain alkyl groups (although branched-chain alkyl groups may also be used) and are end-capped with at least one halogen group, preferably one halogen group, often one chlorine group. Haloalkyl PTM groups for use in the present invention have the chemical structure -(CH2)v Preferably, it is represented by -halo, where v is any integer from 2 to about 12, often from about 3 to about 8, and more often from about 4 to about 6. Halo can be any halogen, but is preferably Cl or Br, and more often Cl.

[0129] In still other embodiments, the PTM group is: TIFF2025128169000090.tif29128 groups wherein w is 0 to 3, preferably 1 or 2. This group selectively binds to the estrogen receptor and is useful for treating diseases modulated by the estrogen receptor, particularly cancer, such as breast cancer, endometrial cancer, ovarian cancer, and uterine cancer in particular.

[0130] The present invention can be used to treat a number of disease states and / or conditions, including any disease state and / or condition in which a protein is dysregulated and in which the patient would benefit from protein degradation.

[0203] General synthetic approach A general scheme for the synthesis of ULM derivatives is now described. Briefly, compounds of the present invention are synthesized according to a general solution-phase synthesis scheme (shown below) and / or general scheme I for the solution-phase synthesis of compounds of the present invention. First, a hydroxyl-protected carboxy-substituted (and protected) pyrrolidine compound is reacted with a carboxylic acid-containing reagent, thereby introducing a carbonyl group at the amine of the pyrrolidine ring to form an amide group. Alternatively, the pyrrolidine amine can be protected, and an amide can be obtained on the right-hand side of the pyrrolidine moiety by condensing the carboxylic acid moiety with a nucleophilic group on the right-hand side. It is preferred that the left-hand and right-hand side fragments to be condensed onto the amine and carboxylic acid groups, respectively, of the pyrrolidine moiety are prepared prior to condensation onto the pyrrolidine group, although other approaches for introducing groups onto the pyrrolidine group may be employed. The individual components that are combined to produce the ULM group can be prepared by using a blocking group at a preferred functional group on the ULM group, which can be removed to react and covalently bond with a PTM moiety already attached to the protein binding moiety, or with a linker group prepared to accommodate the PTM group, or which can be further reacted to form a covalent bond with a PTM group, which may include a ULM' group as described elsewhere herein. Thus, condensation of a carboxylic acid-containing left-hand side fragment onto the amine group of the pyrroline yields R, as shown below: 1 An amide group can be formed with the left-hand fragment. Any number of nucleophilic (preferably amine-containing) right-hand fragments (pre-synthesized) can be condensed onto the carboxyl group to form the R 2 An amide group with the right fragment can be obtained. Formation of presynthesized groups to be condensed onto the amine and / or carboxyl moieties of the pyrrolidine proceeds readily. Solid-phase synthesis may also be used, which employs methods similar to those used in solution-phase synthesis, with the major difference being that the hydroxyl group can be attached to a solid support while other steps of the synthesis are carried out. The general synthetic method is applicable to virtually all compounds of the present invention, and easy modifications are made in accordance with the state of the art of chemical synthesis, either directly using or adapted from the specific teachings of the following examples.

[0205] liquid phase method Solution-phase synthesis, the technique traditionally used by most synthetic organic chemists, is favored by many for library construction due to the relatively wide range of organic reactions available, and products in solution can be relatively easily identified and characterized in standard drug targeting assays. The problem with solution-phase synthesis one molecule at a time is that final purification can be expensive and slow. Chromatography is typically the first resort, as it usually works well. Furthermore, the problems associated with solution-phase chemistry become complicated when attempting to generate libraries or "books" for libraries by making tens of thousands of compounds.

[0206] Numerous methods have been devised for generating compound libraries, which has led to the widespread use of large libraries of chemicals that facilitate the discovery of potential drug candidates. The generation of solution-free chemical libraries is typically the goal of most in the pharmaceutical industry. This goal is due to the nature of many drug targets and related assays. Furthermore, the construction and utility of chemical libraries is typically facilitated by the generation of master plates of compounds in solution that form the basis of the chemical library. Therefore, the general advantages of solid-phase synthesis methods are typically not fully realized in current drug discovery efforts. This is primarily because the focus is not on the binding of the compound to the drug target, but rather on demonstrating that the activity of the drug target is altered, which typically requires the compound to be solution-free. Additional challenges with solid-phase compound libraries arise from the potential impact of linkers and steric effects on solid-phase-bound compounds.

[0207] Thus, methods for the discovery of compounds that bind to target molecules are known in the art, and the optimization of initially discovered compounds, where affinity is improved by generating pools of related compounds through more selective combinatorial chemistry approaches, is also well known in the art.

[0208] The present invention provides a mechanism for overcoming these problems in drug and small molecule discovery.

[0209] Addition of ubiquitin ligase binding moiety (ULM) At this point in the compound discovery pathway for the present invention, the target protein binding elements of the compounds of the present invention have been identified. These optimal binding molecules are then subjected to further chemical reactions to add ubiquitin ligase binding moieties (ULMs) in accordance with the disclosure of this application.

[0210] Regulation of protein levels The present invention also relates to a method for the control of protein levels in cells, which is based on the use of compounds of the present invention that are known to interact with specific target proteins, such that the amount of the protein in a biological system is controlled, preferably to a specific therapeutic effect, by degradation of the target protein in vivo.

[0234] LCMS data were also collected on an Agilent infinity 1260 LC; Agilent 6230 TOF mass spectrometer. Analyses were performed on a Poroshell 120 EC C18 column (50 mm x 3.0 mm internal diameter, 2.7 μm packing diameter) at 45 °C.

[0235] The eluents used were as follows: A = 0.1% v / v formic acid in water. B = 0.1% v / v formic acid in acetonitrile.

[0236] The gradient used was as follows: TIFF2025128169000256.tif57128

[0237] Ultraviolet detection was performed with an average signal between 210 nm and 350 nm wavelength, and mass spectra were recorded on a mass spectrometer using positive mode electrospray ionization.

[0238] Unless otherwise stated, all LC-MS data reported was based on the instrumentation and methods described above. All compounds were prepared with LC-MS purity >95% unless otherwise stated.

[0239] Below are the mobile phases and gradients used when the compounds underwent purification by mass-directed automated preparative HPLC.

[0240] Mass-directed automated preparative HPLC (formic acid modifier) HPLC analysis was carried out on a Sunfire C18 column (150 mm×30 mm id, 5 μm packing diameter) at ambient temperature.

[0241] The solvents used were as follows: A = 0.1% v / v formic acid in water. B = 0.1% v / v formic acid in acetonitrile.

[0242] Mass-directed automated preparative HPLC (trifluoroacetic acid modifier) HPLC analysis was carried out on a Sunfire C18 column (150 mm×30 mm id, 5 μm packing diameter) at ambient temperature.

[0243] The solvents used were as follows: A = 0.1% v / v aqueous trifluoroacetic acid solution. B = 0.1% v / v trifluoroacetic acid in acetonitrile.

[0244] Mass-Directed Automated Preparative HPLC (Ammonium Bicarbonate Modifier) HPLC analysis was carried out on an XBridge C18 column (150 mm×30 mm id, 5 μm packing diameter) at ambient temperature.

[0245] The solvents used were as follows: A = 10 mM ammonium bicarbonate solution adjusted to pH 10 with ammonia solution. B = acetonitrile.

[0246] For each mass-directed automated preparative purification, regardless of the modifier used, the gradient used depended on the retention time recorded in the analytical LCMS of the particular compound undergoing purification and was as follows: For compounds with analytical LCMS retention times below 0.6 minutes, the following gradient was used: TIFF2025128169000257.tif50128For compounds with analytical LCMS retention times between 0.6 and 0.9 minutes, the following gradient was used: TIFF2025128169000258.tif50128For compounds with analytical LCMS retention times between 0.9 and 1.2 minutes, the following gradient was used: TIFF2025128169000259.tif50128For compounds with analytical LCMS retention times between 1.2 and 1.4 minutes, the following gradient was used: TIFF2025128169000260.tif50128

[0247] Ultraviolet detection was by averaging the signal between 210 nm and 350 nm wavelength, and mass spectra were recorded on a mass spectrometer using alternating scan positive-negative mode electrospray ionization.

[0248] Preparative HPLC purification was also performed on a Waters® UV-Directed Purification System equipped with a 2545 Binary Gradient Module, a 2767 Sample Manager, and a 2489 UV / Visible Detector, controlled by MassLynx V4.1 software. All purification work was completed using the following columns: Atlantis Prep T3 OBD Column, SunFire Prep C18 OBD Column, and XBridge Prep Phenyl OBD Column. The mobile phase consisted of water (containing 0.1% TFA or 0.01% NH4HCO3) and acetonitrile, and all reagents used were HPLC grade. The flow rate was 30 ml / min. After the column, a 1:1000 LC packing flow splitter diverted a small portion of the eluent into the UV detector. The electrospray source was set at a capillary voltage of 3.0 kV, a cone voltage of 30 V, a source temperature of 110° C., a desolvation temperature of 350° C., a desolvation gas flow of 600 L / hr, and a cone gas flow of 60 L / hr. In the analyzer, the frequency multiplier was set at 550 for the preparative tune method.

[0249] Following the general synthetic methods described above and as previously described, the following compounds were similarly synthesized:

[0461] Using the approaches mentioned above and various other approaches well documented in the literature, the following exemplary PROTAC compounds were prepared (Tables 3 and 4). The exemplary compounds in Tables 3 and 4 were also assayed for their ability to effect degradation of BRD4 and AR. Accordingly, in certain aspects, the present disclosure provides compounds, including compositions comprising an effective amount of a compound or a derivative, analog, or prodrug thereof in combination with at least one of a pharmaceutically acceptable carrier, another active agent, including a second PROTAC molecule described herein, or a combination thereof. In further aspects, the present disclosure provides methods of treating a disease or condition in a subject in need thereof, comprising administering a composition comprising an effective amount of a compound listed below, wherein the composition is effective to treat or ameliorate the symptoms of the disease or condition.

[0462] Cell-based assays 1. Fluorescence Polarization Assay The ability of VHL ligands to compete for the HIF 1a binding site on VCB was determined via a fluorescence polarization competition assay as described in Buckley et al. JACS, 2012, 134, 4465-4468, WO 2013 / 106643, and US 2014-0356322, which are incorporated by reference in their entireties for all purposes.

[0463] 2. Androgen Receptor ELISA Assay In this assay, compounds were evaluated in LNCaP and / or VCaP cells using a similar protocol. The protocol used in VCaP cells is described below. The androgen receptor ELISA assay was performed using PathScan AR ELISA (Cell Signaling Cat. No. 12850) according to the following assay steps:

[0464] VCaP cells are seeded at 30,000 cells / well in 200 μL / well of Corning 3904 plates in VCaP assay medium [phenol red-free RPMI (Gibco catalog number 11835-030); 5% charcoal-stripped (dextran-treated) FBS (Omega Scientific, catalog number FB-04); Pen / Strep Life Technologies (Gibco catalog number: 10378-016); 0.1 nM R1881 (Sigma, catalog number R0908) is added at the beginning of the assay, not during the initial plating of cells]. Cells are allowed to grow for a minimum of 3 days.

[0465] Cells are initially dosed with compounds diluted in 0.1% DMSO - using polypropylene plates according to the following protocol: (1)(i) Make a 1000x stock plate in DMSO; (ii) Dilute the 20mM stock 1 / 6.7 with DMSO (5µL + 28.3µL DMSO) to 3mM and place in row H; (iii) Serially dilute from row H to row B at 1 / 2 log doses (10µL PROTAC + 20µL DMSO). Reserve row A for DMSO; (iv) Seven doses total (final concentrations in this 1000x plate will be 3mM, 1mM, 333µM, 111µM, etc.). (2)(i) Make a 10x stock plate in media; (ii) Transfer 2.5µL of the 1000x stock to a new 10x stock plate (using a 12-channel pipette, starting with A (DMSO control) and working down to H). When 247.5 μL of medium is added to this plate, it serves as the 10× stock; (iii) make medium + 1 nM R1881 to make the 10× stock plate; (iv) add 247.5 μL of medium with 1 nM R1881 to each well of the 10× stock plate and mix.

[0466] Next, add 22 μL of the 10x stock to the cells and incubate for 24 hours. Make 1x Cell Signaling Cell Lysis Buffer (Cat. No. 9803; provided with the kit) - prepare 50 μL / well. Keep on ice. Aspirate the media and add 50 μL / well of 1x Cell Lysis Buffer. Place the cells on ice for 10 minutes. Mix the solution, transfer to a PCR plate, and centrifuge at 4000 rpm for 10 minutes at 4°C.

[0467] Transfer 5 μL to a new plate (use immediately or freeze at -80°C) and add 115 μL ELISA diluent (0.15 μg / ml to 0.075 μg / ml; provided with PathScan ELISA).

[0468] Add 100 μL / well AR Elisa; Cover and shake for 2 hours at 37°C; Open, tap, and wash with 200 μL 4x ELISA wash buffer; Add 100 μL / well mouse AR detection Ab; Cover and shake for 1 hour at 37°C; Open, tap, and wash with 200 μL 4x ELISA wash buffer; Add 100 μL / well anti-mouse HRP-conjugated Ab (provided in the kit); Cover and shake for 30 minutes at 37°C; Allow TMB reagent to reach room temperature; Open, tap, and wash with 200 μL 4x Elisa wash buffer; Tap; Add 100 μL TMB and shake for 5 minutes - observe color. Add stop reagent when a light blue color develops. Add 100 μL stop solution; Shake and read at 450 nM.

[0469] Prostate cancer progression in patients treated with antiandrogen therapy typically involves one of several mechanisms of enhanced androgen receptor (AR) signaling, including increased intratumoral androgen synthesis, increased AR expression, and AR mutations. PROTACs (proteolysis targeting chimeras) use bifunctional molecules that simultaneously bind to a selected target and an E3 ligase, resulting in induced access, ubiquitination, and degradation of the targeted pathogenic protein. In contrast to traditional target inhibition, which is a competitive process, degradation is a gradual process. Therefore, degradation is less likely to result in increased endogenous ligands, target expression, or mutations in the target. Therefore, this technology appears ideal for addressing mechanisms of AR resistance in prostate cancer patients.

[0470] AR PROTACs degrade AR in LNCaP and VCaP cells with nM-pM potency, resulting in a greater than 85% reduction in AR concentrations (D max ) degradation was rapid, with 50% of AR lost within 15 minutes, and maximum degradation was observed at 4 hours. The duration of AR knockdown was prolonged, with no recovery of AR observed over several days. The degradation process in cells was specific, as PROTACs with an inactive epimer for E3 ligase binding did not degrade AR. AR PROTACs induced rapid apoptosis and cell death in VCaP cells. In LNCap and VCaP cell lines, AR PROTACs were activated under conditions in which enzalutamide was inactive, such as increasing concentrations of the AR agonist R1881, and when cells were AR-inactive. F876L Under conditions containing the mutation, AR PROTACs were antiproliferative. Typically, AR PROTACs are antiproliferative for several hours after intraperitoneal or subcutaneous injection. 1 / 2 In mice, the AR PROTAC demonstrated in vivo activity, including seminal vesicle atrophy, reduced AR protein levels in the prostate, and regression of VCaP tumors.

[0471] The androgen receptor ELISA assay described above was used to generate the results shown in Table 3, where compound potency was determined by the maximum observed percent androgen receptor degradation (D max ) was characterized.

[0472] BDR4 receptor ELISA assay (Table 4) 22RV-1 cells were seeded at 30,000 cells / well in 75 μL / well of RPMI + 10% FBS medium in 96-well plates and grown overnight at 37°C. Cells were dosed with 4x concentrations of compounds diluted in 0.4% DMSO, and compounds were serially diluted 1:3 in an 8-point dose curve. 25 μL of compound was added to the cells at final concentrations starting from 300 nM-0.3 nM in 0.1% DMSO and incubated for 18 hours. The medium was aspirated, and the cells were washed once with PBS and aspirated. Cells were lysed in 50 μL of RIPA buffer (50 mM Tris pH 8, 150 mM NaCl, 1% Tx-100, 0.1% SDS, 0.5% sodium deoxycholate) supplemented with protease and phosphatase inhibitors. The plate was incubated on ice for 15 minutes and then centrifuged at 4000 rpm for 10 minutes at 4°C. 50 μl of the clarified lysate was added from the 96-well assay plate to a 96-well c-myc ELISA plate (Novex, Life Technologies catalog number KH02041). The c-myc standards were reconstituted in standard dilution buffer to produce a standard curve ranging from 333 pg / ml to 0 pg / ml and diluted 1:2 in an 8-point dose curve. The remainder of the assay was performed according to the c-myc ELISA kit protocol. Data were analyzed and plotted using GraphPad Prism software.

[0473] Surface plasmon resonance assay Surface plasmon resonance (SPR) experiments were performed on a Biacore 3000 (GE Healthcare). 2+His-tagged VHL protein was immobilized onto a carboxymethylated dextran surface using chelation with nitriloacetic acid (NTA). The prepared surface was equilibrated for 3 hours in running buffer (Ambion 1x PBS buffer, pH 7 / 4, 0.005% Tween, 2% DMSO).

[0474] All compounds were prepared in 100% DMSO stock plates and serially diluted 3-fold to a top concentration of 5 mM. Compounds were transferred from the stock plate to the assay plate and diluted in running buffer without DMSO. All compounds were run as a 6-concentration series, with a final assay top concentration of 100 μM. Data analysis was performed with Scrubber 2 (BioLogic software, Campbell, Australia). Blanks were subtracted and data were corrected for DMSO using a standard DMSO curve. All reported KD values ​​represent the average of at least N=2 and were obtained by fitting a minimum of five concentrations using a 1:1 fitting algorithm.
