BACKGROUND
10021 1. Field of the Discovery. The present description relates to bifunctional compounds, which are useful for the modifying the ubiquitination and subsequent degradation of target polypeptides and proteins, in particular, androgen receptor. In certain aspects, the compounds comprise a Von Hippel-Lindau (VHL) binding moiety, which binds to the VHL E3 ubiquitin ligase, a target protein binding moiety, which binds to the target protein (e.g., androgen receptor), and optionally a linker moiety which links the VHL binding moiety and target protein binding moiety.These compounds work in such way that the target protein/polypeptide is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein (e.g., androgen receptor).
1003] 2. Background Information. Androgen Receptor (AR) belongs to a nuclear hormone receptor family that is activated by androgens, such as testosterone and dihydrotestosterone (Phctrmacol. Rev. 2006, 58(4), 782-97; Dim. Horm. 1999, 55:309-52.). In the absence of androgens, AR is bound by Heat Shock Protein 90 (Hsp90) in the cytosol. When an androgen binds AR, its conformation changes to release AR from Hsp90 and to expose the Nuclear Localization Signal (NLS). The latter enables AR to translocate into the nucleus where AR acts as a transcription factor to promote gene expression responsible for male sexual characteristics (Endoc.r. Rev. 1987, 8(1):1-28; Mo/. Endocrinol. 2002, 16(10), 2181-7). AR

10041 While AR is responsible for development of male sexual characteristics, it is also a well-documented oncogene in certain forms cancers including prostate cancers (Enclocr. Rev.
2004, 25(2), 276-308). A commonly measured target gene of AR activity is the secreted Prostate Specific Antigen (PSA) protein.

CROSS-REFERENCE TO RELATED APPLICATIONS
1001] The present disclosure is an International Patent Application claiming priority to U.S. Patent Application Serial No. 15/663,273, which is a Continuation-In-Part of U.S.
Nonprovisional Application Serial No. 15/002,303, filed 20 January 2016, which claims the benefit of, and priority to, U.S. Provisional Patent Application Serial No.
62/105,210, filed 20 January 2015 and entitled: Compounds and Methods for the Targeted Degradation of the Androgen Receptor, all of which are incorporated herein by reference in their entireties.
BACKGROUND
10021 1. Field of the Discovery. The present description relates to bifunctional compounds, which are useful for the modifying the ubiquitination and subsequent degradation of target polypeptides and proteins, in particular, androgen receptor. In certain aspects, the compounds comprise a Von Hippel-Lindau (VHL) binding moiety, which binds to the VHL E3 ubiquitin ligase, a target protein binding moiety, which binds to the target protein (e.g., androgen receptor), and optionally a linker moiety which links the VHL binding moiety and target protein binding moiety.These compounds work in such way that the target protein/polypeptide is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein (e.g., androgen receptor).
1003] 2. Background Information. Androgen Receptor (AR) belongs to a nuclear hormone receptor family that is activated by androgens, such as testosterone and dihydrotestosterone (Phctrmacol. Rev. 2006, 58(4), 782-97; Dim. Horm. 1999, 55:309-52.). In the absence of androgens, AR is bound by Heat Shock Protein 90 (Hsp90) in the cytosol. When an androgen binds AR, its conformation changes to release AR from Hsp90 and to expose the Nuclear Localization Signal (NLS). The latter enables AR to translocate into the nucleus where AR acts as a transcription factor to promote gene expression responsible for male sexual characteristics (Endoc.r. Rev. 1987, 8(1):1-28; Mo/. Endocrinol. 2002, 16(10), 2181-7). AR
deficiency leads to Androgen Insensitivity Syndrome, formerly termed testicular feminization.
10041 While AR is responsible for development of male sexual characteristics, it is also a well-documented oncogene in certain forms cancers including prostate cancers (Enclocr. Rev.
2004, 25(2), 276-308). A commonly measured target gene of AR activity is the secreted Prostate Specific Antigen (PSA) protein. The current treatment regimen for prostate cancer involves inhibiting the androgen-AR axis by two methods. The first approach relies on reduction of androgens, while the second strategy aims to inhibit AR function (Nat. Rev.

An alternative approach for the treatment of prostate cancer involves eliminating the AR protein. Because AR is a critical driver of tumorigenesis in many forms of prostate cancers, its elimination should lead to therapeutically benefical response.
[005] There exists an ongoing need in the art for effective treatments for diseases and conditions that are related to aberrant AR regulation or activity, such as, for example, cancer, prostate cancer, and Kennedy's Disease.

BRIEF DESCRIPTION OF THE DRAWINGS
[031] The accompanying drawings, which are incorporated into and form a part of the specification, illustrate several embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating an embodiment of the invention and are not to be construed as limiting the invention. Further objects, features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying figures showing illustrative embodiments of the invention, in which:
1032] Figure 1A and Figure 1B. Illustration of general principle for PROTAC
function. Figure 1A: Exemplary PROTACs comprise an androgen receptor targeting moiety (ABM; darkly shaded rectangle), a Von Hippel-Lindau (VHL) E3 ubiquitin ligase binding moiety (VLM; lightly shaded triangle), and a linker moiety (L; black line) coupling or tethering the ABM to the VLM (as described herein, L can be absent or a bond or a chemical linker moiety). Figure 1B Illustrates the functional use of the PROTACs as described herein. Briefly, the VLM recognizes and binds to Von Hippel-Lindau (VHL) E3 ubiquitin ligase, and the ABM
binds and recruits androgen receptor and brings it into close proximity to the Von Hippel-Lindau (VHL) E3 ubiquitin ligase. Typically, the E3 ubiquitin ligase is complexed with an E2 ubiquitin-conjugating protein, and either alone or via the E2 protein catalyzes attachment of ubiquitin (dark circles) to a lysine on the target protein via an isopeptide bond. The poly-ubiquitinated protein (far right) is then targeted for degration by the proteosomal machinery of the cell.
1033] Figure 2. Apoptosis in VCaP cells. VCaP cells were cultured in Charcoal Stripped Serum containing media supplemented with 0.1 nM R1881 for 48 hrs. The degree of apoptosis was ascertained with CaspaseGlo assay (Promega). These results demonstrated that PROTACs are much more potent in inducing apoptosis than an AR antagonist enzalutamide.
Further, the degree of AR degradation correlates with their ability to induce apoptosis in VCaP
cells.

F876L cells observed with treatment with Example 1 as compared to enzalutamide. LNCaP cells transduced with AR F876L construct were cultured in Charcoal Stripped Serum containing media.
1035] Figure 4. PSA suppression in LNCaP F876L. LNCaP cells transduced with AR
F876L construct were cultured in Charcoal Stripped Serum containing media supplemented with 0.1 nM R1881 for 7 days. The results demonstrated that AR PROTAC is able to suppress the transcriptional activity of AR in F876L containing cells.
10361 Figure 5. Prostate involution in C57B6 mouse model. 12-week old male C57B1J6 mice were treated with AR PROTAC Example 163 and its inactive epimer analog Compound A which is unable to bind to VHL E3 ligase. Enzalutamide (PO, QD, 30 mpk), Example 163 (IP, QD, 1 and 3 mpk) and Compound A (IP, QD, 1 and 3 mpk) were administered for 10 days, upon which the prostates were isolated and weighed. These results demonstrated that the ability of PROTAC Example 163 to degrade AR leads to significant prostate involution in mice at very low doses.
[037] Figure 6. Tumor growth inhibition in VCaP xenograft model. VCaP cells were implanted into CB17 scid mice subcutaneously. Once the tumors were palpable, the mice were castrated, leading to temporary tumor stasis. Upon regrowth of tumors, the mice were dosed with enzalutamide (PO. QD, 30 mpk) or AR PROTAC Example 163 (lP, QD, at 30, 10 and 3 inpk) as indicated. Tumor growth inhibition was observed in all treatment arms.

Figure 7A: AR PROTAC Example 1 was added to LNCaP cells at indicated concentrations for 24 hours in the presence or absence of 10 uM VHL E3 ligase ligand compound B. Figure 7B: LNCaP cells were treated with AR PROTAC Example 1 and its inactive epimer analog compound C which is unable to bind to VHL E3 ligase."

10401 The present description relates to the surprising and unexpected discovery that an E3 ubiquitin ligase protein can ubiquitinate a target protein, in particular androgen receptor, once the E3 ubiquitin ligase protein and the target protein are brought into proximity by a chimeric construct (e.g., PROTAC) as described herein, in which a moiety that binds the E3 ubiquitin ligase protein is coupled, e.g., covalently, to a moiety that bind the androgen receptortarget protein. Accordingly, the present description provides compounds, compositions comprising the same, and associated methods of use for ubiquitination and degradation of a chosen target protein, e.g.. androgen receptor (See Figure lA and Figure 1B).
[041] The present description is related in certain aspects to U.S.
Patent Publication 2014/0356322A1, which is incorporated herein by reference in its entirety for all purposes.
1042] 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. The terminology used in the description is for describing particular embodiments only and is not intended to be limiting of the invention.
[043] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise (such as in the case of a group containing a number of carbon atoms in which case each carbon atom number falling within the range is provided), between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention.
The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the invention.
[044] The following terms are used to describe the present invention. In instances where a term is not specifically defined herein, that term is given an art-recognized meaning by those of ordinary skill applying that term in context to its use in describing the present invention.
[045] The articles "a" and "an" as used herein and in the appended claims 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 indicates otherwise. By way of example, "an element" means one element or more than one element.
1046] The phrase "and/or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e..
elements that are conjunctively present in some cases and disjunctively present in other cases.
Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A
only (optionally including elements other than B); in another embodiment, to B
only (optionally including elements other than A); in yet another embodiment, to both A and B
(optionally including other elements); etc.
[047] As used herein in the specification and in the 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" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as "only one of or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of a number or list of elements. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., "one or the other but not both") when preceded by terms of exclusivity, such as "either," "one of," "only one of," or "exactly one of."
1048] The term "about" and the like, as used herein, in association with numeric values or ranges, reflects the fact that there is a certain level of variation that is recognized and tolerated in the art due to practical and/or theoretical limitations. For example, minor variation is tolerated due to inherent variances in the manner in which certain devices operate and/or measurements are taken. In accordance with the above, the phrase "about" is normally used to encompass values within the standard deviation or standard error.
1049] In the claims, as well as in the specification above, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving,"
"holding,"
"composed of," and the like are to be understood to be open-ended, i.e., to mean 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.
[050] As used herein in the specification and in the 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 anyone or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those elements specifically identified. Thus, as a nonlimiting 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 refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A);
in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one. B (and optionally including other elements); etc.
[051] It should also be understood that, in certain methods described herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited unless the context indicates otherwise.
[052] The terms "co-administration" and "co-administering" or "combination therapy"
can refer to both concurrent administration (administration of two or more therapeutic agents at the same time) and time varied administration (administration of one or more therapeutic agents at a time different from that of the administration of an additional therapeutic agent or agents), as long as the therapeutic agents are present in the patient to some extent, preferably at effective amounts, at the same time. In certain preferred aspects, one or more of the present compounds described herein, are coadministered in combination with at least one additional bioactive agent, especially including an anticancer agent. In particularly preferred aspects, the co-administration of compounds results in synergistic activity and/or therapy, including anticancer activity.
[053] The term "effective" can mean, but is in no way limited to, that amount/dose of the active pharmaceutical ingredient, which, when used in the context of its intended use, effectuates or is sufficient to prevent, inhibit the occurrence, ameliorate, delay or treat (alleviate a symptom to some extent, preferably all) the symptoms of a condition, disorder or disease state in a subject in need of such treatment or receiving such treatment. The term effective subsumes all other effective amount or effective concentration terms, e.g., "effective amount/dose,"
"pharmaceutically effective amount/dose" or "therapeutically effective amount/dose," which are otherwise described or used in the present application.
[054] The effective amount depends on the type and severity of disease, the composition used, the route of administration, the type of mammal being treated, the physical characteristics of the specific mammal under consideration, concurrent medication, and other factors which those skilled in the medical arts will recognize. The exact amount can be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams &
Wilkins).
[055] The term "pharmacological composition," "therapeutic composition,"
"therapeutic formulation" or "pharmaceutically acceptable formulation" can mean, but is in no way limited to, a composition or formulation that allows for the effective distribution of an agent provided by the invention, which is in a form suitable for administration to the physical location most suitable for their desired activity, e.g., systemic administration.
1056] The term "pharmaceutically acceptable" or "pharmacologically acceptable" can mean, but is in no way limited to, entities and compositions that do not produce an adverse, allergic or other untoward reaction when administered to an animal, or a human, as appropriate.
[057] The term "pharmaceutically acceptable carrier" or "pharmacologically acceptable carrier" can mean, but is in no way limited to, any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Suitable carriers are described in the most recent edition of Remington's Pharmaceutical Sciences, a standard reference text in the field, which is incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, finger's solutions, dextrose solution, and 5%
human serum albumin.
Liposomes and non-aqueous vehicles such as fixed oils may also be used. The use of such media and agents for pharmaceutically active substances is well known in the art.
Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds can also be incorporated into the compositions.
1058] The term "systemic administration" refers to a route of administration that is, e.g., enteral or parenteral, and results in the systemic distribution of an agent leading to systemic absorption or accumulation of drugs in the blood stream followed by distribution throughout the entire body. Suitable forms, in part, depend upon the use or the route of entry, for example oral, transdermal, or by injection. Such forms should not prevent the composition or formulation from reaching a target cell (i.e., a cell to which the negatively charged polymer is desired to be delivered to). For example, pharmacological compositions injected into the blood stream should be soluble. Other factors are known in the art, and include considerations such as toxicity and forms which prevent the composition or formulation from exerting its effect.
Administration routes which lead to systemic absorption include, without limitations:
intravenous, subcutaneous, intraperitoneal, inhalation, oral, intrapulmonary and intramuscular. The rate of entry of a drug into the circulation has been shown to be a function of molecular weight or size. The use of a liposome or other drug carrier comprising the compounds of the instant invention can potentially localize the drug, for example, in certain tissue types, such as the tissues of the reticular endothelial system (RES). A liposome formulation which can facilitate the association of drug with the surface of cells, such as, lymphocytes and inacrophages is also useful.
1059] The term "local administration" refers to a route of administration in which the agent is delivered to a site that is apposite or proximal, e.g., within about 10 cm, to the site of the lesion or disease.
[060] The term "compound", as used herein, unless otherwise indicated, refers to any specific chemical compound disclosed herein and includes tautomers, regioisomers, geometric isomers, and where applicable, stereoisomers, including optical isomers (enffiniomers) and other steroisomers (diastereoiners) thereof, as well as pharmaceutically acceptable salts and derivatives (including prodrug forms) thereof where applicable, in context. Within its use in context, the term compound generally refers to a single compound, but also may include other compounds such as stereoisomers, regioisomers and/or optical isomers (including racemic mixtures) as well as specific enantiomers or enantiomerically enriched mixtures of disclosed compounds. The term also refers, in context to prodrug forms of compounds which have been modified to facilitate the administration and delivery of compounds to a site of activity. It is noted that in describing the present compounds, numerous substituents and variables associated with same, among others, are described.
[061] It is understood by those of ordinary skill that molecules which are described herein are stable compounds as generally described hereunder. When the bond is shown, both a double bond and single bond are represented within the context of the compound shown.
[062] As used herein, "derivatives" can mean compositions formed from the native compounds either directly, by modification, or by partial substitution. As used herein, "analogs"
can mean compositions that have a structure similar to, but not identical to, the native compound.
1063] The term "Ubiquitin Ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to a specific substrate protein, targeting the substrate protein for degradation. By way of example, Von Hippel-Lindau E3 Ubiquitin Ligase or VCB
E3 Ubiquitin Ligase is protein that alone or in combination with an E2 ubiquitin-conjugating enzyme causes the attachment of ubiquitin to a lysine on a target protein, and subsequently targets the specific protein substrates for degradation by the proteasome. Thus, E3 ubiquitin ligase alone or in complex with an E2 ubiquitin conjugating enzyme is responsible for the transfer of ubiquitin to targeted proteins. In general, the ubiquitin ligase is involved in polyubiquitination such that a second ubiquitin is attached to the first; a third is attached to the second, and so forth.
Polyubiquitination marks proteins for degradation by the proteasome. However, there are some ubiquitination events that are limited to mono-ubiquitination, in which only a single ubiquitin is added by the ubiquitin ligase to a substrate molecule. Mono-ubiquitinated proteins are not targeted to the proteasome for degradation, but may instead be altered in their cellular location or function, for example, via binding other proteins that have domains capable of binding ubiquitin.
Further complicating matters, different lysines on ubiquitin can be targeted by an E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin, which is recognized by the proteasome.
[064] The term "subject" is used throughout the specification to describe a cell, tissue, or animal, preferably a mammal, e.g., a human or a domesticated animal, to whom treatment, including prophylactic treatment, with the compositions according to the present invention is provided. For treatment of those infections, conditions or disease states which are specific for a specific animal such as a human patient, the term patient refers to that specific animal, including a domesticated animal such as a dog or cat or a farm animal such as a horse, cow, sheep, etc. In general, 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.
[065] Compounds [066] In one aspect, the present invention provides compounds useful for regulating protein activity. The composition comprises a ubiquitin pathway protein binding moiety (preferably for an E3 ubiquitin ligase, alone or in complex with an E2 ubiquitin conjugating enzyme which is responsible for the transfer of ubiquitin to targeted proteins) according to a defined chemical structure and a protein targeting moiety which are linked or coupled together, preferably through a linker, wherein the ubiquitin pathway protein binding moiety recognizes an ubiquitin pathway protein and the targeting moiety recognizes a target protein (e.g., androgen receptor). Such compounds may be referred to herein as PROTAC compounds or PROTACs.
[067] In one aspect, the description provides AR binding moieties (ABM). In certain embodiments, the compounds having the following general structure: ABM-L, wherein ABM is an AR binding moiety as described herein, and L is a chemical linker moiety, e.g., a linker as described herein, or optionally a bond. In certain embodiments, the ABM and/or L are coupled to a ULM as described herein below.
[068] In another aspect, the disclosure provides compounds which function to recruit androgen receptor (AR) proteins to E3 LTbiquitin Ligase for ubiquintination and degradation. In certain embodiments, the compounds have the following general structure:
[069] ABM ¨L¨ULM (I), 1070]
wherein ULM is an E3 ligase binding moiety, ABM is an AR binding moiety, which binds to an AR protein and L is a bond or a chemical linker moiety which links the ABM
and ULM.
[071] In certain embodiments, the ULM is a moiety specific for an E3 ubiquitin ligase such as, e.g., Von Hippel-Lindau E3 ubiquitin ligase (VHL), cereblon, mouse double minute 2 homolog (Mdm2), or inhibitor of apoptosis (IAP), wherein the ULM moiety is coupled to an ABM as described herein.
[072] Without being bound by any particular theory, it is hypothesized that due at least in part to the proximity of AR and the E3 ubiquitin ligase, the AR is ubiquitinated by the ubiquitin ligase and degraded. In certain embodiments, the ABM is chemically linked or coupled directly to the ULM: group. In certain additional embodiments, the ABM
is chemically linked or coupled to the ULM via a chemical linker moiety. In additional embodiments, the description provides compounds having the following general structure:
[073] ABM ¨L¨VLM (11), [074] wherein ABM is an AR binding moiety and VLM is a Von Hippel-Lindau E3 Ubiquitin Ligase (VHL) binding moiety,and L is a bond or a chemical linker moiety which links the ABM and VLM. The ULM or VLM group and ABM group may be covalently linked to the linker group through any covalent bond which is appropriate and stable to the chemistry of the linker.
1075] In certain embodiments, the ULM or VLM comprises a hydroxyproly1 moiety.
The hydroxyl prolyl moiety has been shown to be importantn for binding and recruiting of the VHL protein.
[076] It will be understood that the general structures are exemplary and the respective moieties can be arranged in any desired order or configuration, e.g., ULM-L-AB
M, and VLM-L-ABM respectively. In certain additional embodiments, the compounds comprise a plurality of E3 ligase binding moieties and/or a plurality of ABMs.
1077] In certain embodiments, ABM alone, without forming ABM-L-ULM, provides desired properties in regulating protein activity.

10137] In additional embodiments, the linker group is optionally substituted (poly)ethyleneglycol having between 1 and about 100 ethylene glycol units, between about 1 and about 50 ethylene glycol units, between 1 and about 25 ethylene glycol units, between about 1 and 10 ethylene glycol units, between 1 and about 8 ethylene glycol units and 1 and 6 ethylene glycol units, between 2 and 4 ethylene glycol units,or optionally substituted alkyl groups interdispersed with optionally substituted, 0, N, S, P or Si atoms. In certain embodiments, the linker is substituted with an aryl, phenyl, benzyl, alkyl, alkylene, or heterocycle group. In certain embodiments, the linker may be asymmetric or symmetrical.
[0138] In certain aspects the description provides a PROTAC compound in which the linker is cleavable in vivo into a functional E3 ligase binding moiety, and target protein binding moiety. In this regard, and without being bound by any particular theory, it is hypothesized that such a configuration can potentiate the beneficial effects of the degradation activity of the intact PROTAC molecule. Thus, in certain embodiments, the linker is configured or "tuned" to have the desired kinetics of cleavage into functional component molecules or active metabolites. In certain embodiments, the enzyme responsible for cleavage of the linker is a liver enzyme, such as, e.g., oxidases, peroxidase, reductases, transferases, dehydrogenases, peroxidases. In certain embodiments, the enzyme is at least one of cytochrome P450 oxidase, e.g., CYP3A4, Flavin-containing monooxygenase, alcohol dehydrogenase, aldehyde dehydrogenase, monoamine oxidase, peroxidase, glutathione S-transferase, cytochrome P450 reductase, sulfotransferase, methyltransferase, N-acetyltransferase, glucuronosyltransferase, transpeptidase, or combination thereof.
[0139] Exemplary Androaen Bindina Moieties (ABMs) 101401 In another aspect, the description provides AR binding moieties (ABM), which in certain aspects and embodiments are coupled to a linker and/or a ULM as described herein.
[0141] In any of the compounds described herein, the ABM comprises a chemical moiety that binds to the androgen receptor (AR). Various androgen receptor binding compounds have been described in literature, including various androgen derivatives such as testosterone, dihydrotestosterone, and metribolone (also known as methyltrienolone or R1881), and non-steroidal compounds such as bicalutamide, enzalutamide. Those of ordinary skill in the art would appreciate that these androgen receptor binding compounds could be potentially used as an ABM
moiety in a PROTAC compound. Such literature includes, but not limited to, G.

BRIEF DESCRIPTION OF THE DRAWINGS
[031] The accompanying drawings, which are incorporated into and form a part of the specification, illustrate several embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating an embodiment of the invention and are not to be construed as limiting the invention. Further objects, features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying figures showing illustrative embodiments of the invention, in which:
1032] Figure 1A and Figure 1B. Illustration of general principle for PROTAC
function. Figure 1A: Exemplary PROTACs comprise an androgen receptor targeting moiety (ABM; darkly shaded rectangle), a Von Hippel-Lindau (VHL) E3 ubiquitin ligase binding moiety (VLM; lightly shaded triangle), and a linker moiety (L; black line) coupling or tethering the ABM to the VLM (as described herein, L can be absent or a bond or a chemical linker moiety). Figure 1B Illustrates the functional use of the PROTACs as described herein. Briefly, the VLM recognizes and binds to Von Hippel-Lindau (VHL) E3 ubiquitin ligase, and the ABM
binds and recruits androgen receptor and brings it into close proximity to the Von Hippel-Lindau (VHL) E3 ubiquitin ligase. Typically, the E3 ubiquitin ligase is complexed with an E2 ubiquitin-conjugating protein, and either alone or via the E2 protein catalyzes attachment of ubiquitin (dark circles) to a lysine on the target protein via an isopeptide bond. The poly-ubiquitinated protein (far right) is then targeted for degration by the proteosomal machinery of the cell.

The degree of apoptosis was ascertained with CaspaseGlo assay (Promega). These results demonstrated that PROTACs are much more potent in inducing apoptosis than an AR antagonist enzalutamide.
Further, the degree of AR degradation correlates with their ability to induce apoptosis in VCaP
cells.

DETAILED DESCRIPTION
1039] The following is a detailed description provided to aid those skilled in the art in practicing the present invention. Those of ordinary skill in the art may make modifications and variations in the embodiments described herein without departing from the spirit or scope of the present disclosure. All publications, patent applications, patents, figures and other references mentioned herein are expressly incorporated by reference in their entirety.
10401 The present description relates to the surprising and unexpected discovery that an E3 ubiquitin ligase protein can ubiquitinate a target protein, in particular androgen receptor, once the E3 ubiquitin ligase protein and the target protein are brought into proximity by a chimeric construct (e.g., PROTAC) as described herein, in which a moiety that binds the E3 ubiquitin ligase protein is coupled, e.g., covalently, to a moiety that bind the androgen receptortarget protein. Accordingly, the present description provides compounds, compositions comprising the same, and associated methods of use for ubiquitination and degradation of a chosen target protein, e.g.. androgen receptor (See Figure lA and Figure 1B).
[041] The present description is related in certain aspects to U.S.
Patent Publication 2014/0356322A1, which is incorporated herein by reference in its entirety for all purposes.
1042] 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. The terminology used in the description is for describing particular embodiments only and is not intended to be limiting of the invention.
[043] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise (such as in the case of a group containing a number of carbon atoms in which case each carbon atom number falling within the range is provided), between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention.
The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the invention.
[044] The following terms are used to describe the present invention. In instances where a term is not specifically defined herein, that term is given an art-recognized meaning by those of ordinary skill applying that term in context to its use in describing the present invention.
[045] The articles "a" and "an" as used herein and in the appended claims 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 indicates otherwise. By way of example, "an element" means one element or more than one element.
1046] The phrase "and/or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e..
elements that are conjunctively present in some cases and disjunctively present in other cases.
Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A
only (optionally including elements other than B); in another embodiment, to B
only (optionally including elements other than A); in yet another embodiment, to both A and B
(optionally including other elements); etc.
[047] As used herein in the specification and in the 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" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as "only one of or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of a number or list of elements. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., "one or the other but not both") when preceded by terms of exclusivity, such as "either," "one of," "only one of," or "exactly one of."
1048] The term "about" and the like, as used herein, in association with numeric values or ranges, reflects the fact that there is a certain level of variation that is recognized and tolerated in the art due to practical and/or theoretical limitations. For example, minor variation is tolerated due to inherent variances in the manner in which certain devices operate and/or measurements are taken. In accordance with the above, the phrase "about" is normally used to encompass values within the standard deviation or standard error.
1049] In the claims, as well as in the specification above, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving,"
"holding,"
"composed of," and the like are to be understood to be open-ended, i.e., to mean 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.
[050] As used herein in the specification and in the 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 anyone or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those elements specifically identified. Thus, as a nonlimiting 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 refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A);
in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one. B (and optionally including other elements); etc.
[051] It should also be understood that, in certain methods described herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited unless the context indicates otherwise.
[052] The terms "co-administration" and "co-administering" or "combination therapy"
can refer to both concurrent administration (administration of two or more therapeutic agents at the same time) and time varied administration (administration of one or more therapeutic agents at a time different from that of the administration of an additional therapeutic agent or agents), as long as the therapeutic agents are present in the patient to some extent, preferably at effective amounts, at the same time. In certain preferred aspects, one or more of the present compounds described herein, are coadministered in combination with at least one additional bioactive agent, especially including an anticancer agent. In particularly preferred aspects, the co-administration of compounds results in synergistic activity and/or therapy, including anticancer activity.
[053] The term "effective" can mean, but is in no way limited to, that amount/dose of the active pharmaceutical ingredient, which, when used in the context of its intended use, effectuates or is sufficient to prevent, inhibit the occurrence, ameliorate, delay or treat (alleviate a symptom to some extent, preferably all) the symptoms of a condition, disorder or disease state in a subject in need of such treatment or receiving such treatment. The term effective subsumes all other effective amount or effective concentration terms, e.g., "effective amount/dose,"
"pharmaceutically effective amount/dose" or "therapeutically effective amount/dose," which are otherwise described or used in the present application.
[054] The effective amount depends on the type and severity of disease, the composition used, the route of administration, the type of mammal being treated, the physical characteristics of the specific mammal under consideration, concurrent medication, and other factors which those skilled in the medical arts will recognize. The exact amount can be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams &
Wilkins).
[055] The term "pharmacological composition," "therapeutic composition,"
"therapeutic formulation" or "pharmaceutically acceptable formulation" can mean, but is in no way limited to, a composition or formulation that allows for the effective distribution of an agent provided by the invention, which is in a form suitable for administration to the physical location most suitable for their desired activity, e.g., systemic administration.
1056] The term "pharmaceutically acceptable" or "pharmacologically acceptable" can mean, but is in no way limited to, entities and compositions that do not produce an adverse, allergic or other untoward reaction when administered to an animal, or a human, as appropriate.
[057] The term "pharmaceutically acceptable carrier" or "pharmacologically acceptable carrier" can mean, but is in no way limited to, any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Suitable carriers are described in the most recent edition of Remington's Pharmaceutical Sciences, a standard reference text in the field, which is incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, finger's solutions, dextrose solution, and 5%
human serum albumin.
Liposomes and non-aqueous vehicles such as fixed oils may also be used. The use of such media and agents for pharmaceutically active substances is well known in the art.
Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds can also be incorporated into the compositions.
1058] The term "systemic administration" refers to a route of administration that is, e.g., enteral or parenteral, and results in the systemic distribution of an agent leading to systemic absorption or accumulation of drugs in the blood stream followed by distribution throughout the entire body. Suitable forms, in part, depend upon the use or the route of entry, for example oral, transdermal, or by injection. Such forms should not prevent the composition or formulation from reaching a target cell (i.e., a cell to which the negatively charged polymer is desired to be delivered to). For example, pharmacological compositions injected into the blood stream should be soluble. Other factors are known in the art, and include considerations such as toxicity and forms which prevent the composition or formulation from exerting its effect.
Administration routes which lead to systemic absorption include, without limitations:
intravenous, subcutaneous, intraperitoneal, inhalation, oral, intrapulmonary and intramuscular. The rate of entry of a drug into the circulation has been shown to be a function of molecular weight or size. The use of a liposome or other drug carrier comprising the compounds of the instant invention can potentially localize the drug, for example, in certain tissue types, such as the tissues of the reticular endothelial system (RES). A liposome formulation which can facilitate the association of drug with the surface of cells, such as, lymphocytes and inacrophages is also useful.
1059] The term "local administration" refers to a route of administration in which the agent is delivered to a site that is apposite or proximal, e.g., within about 10 cm, to the site of the lesion or disease.
[060] The term "compound", as used herein, unless otherwise indicated, refers to any specific chemical compound disclosed herein and includes tautomers, regioisomers, geometric isomers, and where applicable, stereoisomers, including optical isomers (enffiniomers) and other steroisomers (diastereoiners) thereof, as well as pharmaceutically acceptable salts and derivatives (including prodrug forms) thereof where applicable, in context. Within its use in context, the term compound generally refers to a single compound, but also may include other compounds such as stereoisomers, regioisomers and/or optical isomers (including racemic mixtures) as well as specific enantiomers or enantiomerically enriched mixtures of disclosed compounds. The term also refers, in context to prodrug forms of compounds which have been modified to facilitate the administration and delivery of compounds to a site of activity. It is noted that in describing the present compounds, numerous substituents and variables associated with same, among others, are described.
[061] It is understood by those of ordinary skill that molecules which are described herein are stable compounds as generally described hereunder. When the bond is shown, both a double bond and single bond are represented within the context of the compound shown.
[062] As used herein, "derivatives" can mean compositions formed from the native compounds either directly, by modification, or by partial substitution. As used herein, "analogs"
can mean compositions that have a structure similar to, but not identical to, the native compound.
1063] The term "Ubiquitin Ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to a specific substrate protein, targeting the substrate protein for degradation. By way of example, Von Hippel-Lindau E3 Ubiquitin Ligase or VCB
E3 Ubiquitin Ligase is protein that alone or in combination with an E2 ubiquitin-conjugating enzyme causes the attachment of ubiquitin to a lysine on a target protein, and subsequently targets the specific protein substrates for degradation by the proteasome. Thus, E3 ubiquitin ligase alone or in complex with an E2 ubiquitin conjugating enzyme is responsible for the transfer of ubiquitin to targeted proteins. In general, the ubiquitin ligase is involved in polyubiquitination such that a second ubiquitin is attached to the first; a third is attached to the second, and so forth.
Polyubiquitination marks proteins for degradation by the proteasome. However, there are some ubiquitination events that are limited to mono-ubiquitination, in which only a single ubiquitin is added by the ubiquitin ligase to a substrate molecule. Mono-ubiquitinated proteins are not targeted to the proteasome for degradation, but may instead be altered in their cellular location or function, for example, via binding other proteins that have domains capable of binding ubiquitin.
Further complicating matters, different lysines on ubiquitin can be targeted by an E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin, which is recognized by the proteasome.
[064] The term "subject" is used throughout the specification to describe a cell, tissue, or animal, preferably a mammal, e.g., a human or a domesticated animal, to whom treatment, including prophylactic treatment, with the compositions according to the present invention is provided. For treatment of those infections, conditions or disease states which are specific for a specific animal such as a human patient, the term patient refers to that specific animal, including a domesticated animal such as a dog or cat or a farm animal such as a horse, cow, sheep, etc. In general, 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.
[065] Compounds [066] In one aspect, the present invention provides compounds useful for regulating protein activity. The composition comprises a ubiquitin pathway protein binding moiety (preferably for an E3 ubiquitin ligase, alone or in complex with an E2 ubiquitin conjugating enzyme which is responsible for the transfer of ubiquitin to targeted proteins) according to a defined chemical structure and a protein targeting moiety which are linked or coupled together, preferably through a linker, wherein the ubiquitin pathway protein binding moiety recognizes an ubiquitin pathway protein and the targeting moiety recognizes a target protein (e.g., androgen receptor). Such compounds may be referred to herein as PROTAC compounds or PROTACs.
[067] In one aspect, the description provides AR binding moieties (ABM). In certain embodiments, the compounds having the following general structure: ABM-L, wherein ABM is an AR binding moiety as described herein, and L is a chemical linker moiety, e.g., a linker as described herein, or optionally a bond. In certain embodiments, the ABM and/or L are coupled to a ULM as described herein below.
[068] In another aspect, the disclosure provides compounds which function to recruit androgen receptor (AR) proteins to E3 LTbiquitin Ligase for ubiquintination and degradation. In certain embodiments, the compounds have the following general structure:
[069] ABM ¨L¨ULM (I), 1070]
wherein ULM is an E3 ligase binding moiety, ABM is an AR binding moiety, which binds to an AR protein and L is a bond or a chemical linker moiety which links the ABM
and ULM.
[071] In certain embodiments, the ULM is a moiety specific for an E3 ubiquitin ligase such as, e.g., Von Hippel-Lindau E3 ubiquitin ligase (VHL), cereblon, mouse double minute 2 homolog (Mdm2), or inhibitor of apoptosis (IAP), wherein the ULM moiety is coupled to an ABM as described herein.
[072] Without being bound by any particular theory, it is hypothesized that due at least in part to the proximity of AR and the E3 ubiquitin ligase, the AR is ubiquitinated by the ubiquitin ligase and degraded. In certain embodiments, the ABM is chemically linked or coupled directly to the ULM: group. In certain additional embodiments, the ABM
is chemically linked or coupled to the ULM via a chemical linker moiety. In additional embodiments, the description provides compounds having the following general structure:
[073] ABM ¨L¨VLM (11), [074] wherein ABM is an AR binding moiety and VLM is a Von Hippel-Lindau E3 Ubiquitin Ligase (VHL) binding moiety,and L is a bond or a chemical linker moiety which links the ABM and VLM. The ULM or VLM group and ABM group may be covalently linked to the linker group through any covalent bond which is appropriate and stable to the chemistry of the linker.
1075] In certain embodiments, the ULM or VLM comprises a hydroxyproly1 moiety.
The hydroxyl prolyl moiety has been shown to be importantn for binding and recruiting of the VHL protein.
[076] It will be understood that the general structures are exemplary and the respective moieties can be arranged in any desired order or configuration, e.g., ULM-L-AB
M, and VLM-L-ABM respectively. In certain additional embodiments, the compounds comprise a plurality of E3 ligase binding moieties and/or a plurality of ABMs.
1077] In certain embodiments, ABM alone, without forming ABM-L-ULM, provides desired properties in regulating protein activity.
1078] In any of the aspects or embodiments of compounds described herein, unless indicated otherwise, the compounds are intended to encompass pharmaceutically acceptable salts, enantiomers, stereoisomers, solvates or polymorphs thereof.

[0138] In certain aspects the description provides a PROTAC compound in which the linker is cleavable in vivo into a functional E3 ligase binding moiety, and target protein binding moiety. In this regard, and without being bound by any particular theory, it is hypothesized that such a configuration can potentiate the beneficial effects of the degradation activity of the intact PROTAC molecule. Thus, in certain embodiments, the linker is configured or "tuned" to have the desired kinetics of cleavage into functional component molecules or active metabolites. In certain embodiments, the enzyme responsible for cleavage of the linker is a liver enzyme, such as, e.g., oxidases, peroxidase, reductases, transferases, dehydrogenases, peroxidases. In certain embodiments, the enzyme is at least one of cytochrome P450 oxidase, e.g., CYP3A4, Flavin-containing monooxygenase, alcohol dehydrogenase, aldehyde dehydrogenase, monoamine oxidase, peroxidase, glutathione S-transferase, cytochrome P450 reductase, sulfotransferase, methyltransferase, N-acetyltransferase, glucuronosyltransferase, transpeptidase, or combination thereof.

10176] Pharmaceutically acceptable base addition salts may also be used to produce pharmaceutically acceptable salt forms of the compounds or derivatives according to the present invention. The chemical bases that may be used as reagents to prepare pharmaceutically acceptable base salts of the present compounds that are acidic in nature are those that form non-toxic base salts with such compounds. Such non-toxic base salts include, but are not limited to those derived from such pharmacologically acceptable cations such as alkali metal cations (eg., potassium and sodium) and alkaline earth metal cations (eg, calcium, zinc and magnesium), ammonium or water-soluble amine addition salts such as N-methylglucamine-(meglumine), and the lower alkanolammonium and other base salts of pharmaceutically acceptable organic amines, among others.
[0177] Compositions [0178] In another aspect, the description provides compositions comprising compounds as described herein, including salts thereof, and a pharmaceutically acceptable carrier. In certain embodiments, the compositions are therapeutic or pharmaceutical compositions comprising an effective amount of a compound as described herein and a pharmaceutally acceptable carrier.
[0179] The amount of compound in a pharmaceutical composition of the instant invention that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host and disease treated, the particular mode of administration.
Generally, an amount between 0.1 mg/kg and 1000 mg/kg body weight/day of active ingredients is administered dependent upon potency of the agent. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50%
of the population) and the ED50 (the dose therapeutically effective in 50% of the population).
The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD50/ED50. Compounds that exhibit large therapeutic indices are preferred.
While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects. The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture.
Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography.
[0180] The compositions of the present invention may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers and may also be administered in controlled-release formulations. Pharmaceutically acceptable carriers that may be used in these pharmaceutical compositions include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as prolamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.
[0181] The active compound is included in the pharmaceutically acceptable carrier or diluent in an amount sufficient to deliver to a patient a therapeutically effective amount for the desired indication, without causing serious toxic effects in the patient treated. A preferred dose of the active compound for all of the herein-mentioned conditions is in the range from about 10 ng/kg to 300 mg/kg, preferably 0.1 to 100 mg/kg per day, more generally 0.5 to about 25 ing per kilogram body weight of the recipient/patient per day. A typical topical dosage will range from 0.01-5% wt/wt in a suitable carrier.
10182] The compound is conveniently administered in any suitable unit dosage form, including but not limited to one containing less than lmg, 1 mg to 3000 mg, preferably 5 to 500 mg of active ingredient per unit dosage form. An oral dosage of about 25-250 mg is often convenient.
[0183] The active ingredient is preferably administered to achieve peak plasma concentrations of the active compound of about 0.00001-30 mM, preferably about 0.1-30 M.
This may be achieved, for example, by the intravenous injection of a solution or formulation of the active ingredient, optionally in saline, or an aqueous medium or administered as a bolus of the active ingredient. Oral administration is also appropriate to generate effective plasma concentrations of active agent.
101841 The concentration of active compound in the drug composition will depend on absorption, distribution, inactivation, and excretion rates of the drug as well as other factors known to those of skill in the art. It is to be noted that dosage values will also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed composition. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at varying intervals of time.
[0185] If administered intravenously, preferred carriers are physiological saline or phosphate buffered saline (PBS).
[0186] In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems.
Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art.
10187] Liposoinal suspensions may also be pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811 (which is incorporated herein by reference in its entirety).
For example, liposome formulations may be prepared by dissolving appropriate lipid(s) (such as stearoyl phosphatidyl ethanolamine, stearoyl phosphatidyl choline, arachadoyl phosphatidyl choline, and cholesterol) in an inorganic solvent that is then evaporated, leaving behind a thin film of dried lipid on the surface of the container. An aqueous solution of the active compound are then introduced into the container. The container is then swirled by hand to free lipid material from the sides of the container and to disperse lipid aggregates, thereby forming the liposomal suspension.

10172] In another embodiment, the present invention provides a library of compounds.
The library comprises more than one compound wherein each compound has a formula of ABM-L-ULM, wherein ULM is a ubiquitin pathway protein binding moiety (preferably, an E3 ubiquitin ligase moiety as otherwise disclosed herein), e.g., a VLM, and ABM
is an AR protein binding moiety, wherein ABM is coupled (preferably, through a linker moiety) to ULM, and wherein the ubiquitin pathway protein binding moiety recognizes an ubiquitin pathway protein, in particular, an E3 ubiquitin ligase.
[0173] The present description includes, where applicable, the compositions comprising the pharmaceutically acceptable salts, in particular, acid or base addition salts of compounds of the present invention.
10174] The term "pharmaceutically acceptable salt" is used throughout the specification to describe, where applicable, a salt form of one or more of the compounds described herein which are presented to increase the solubility of the compound in the gastic juices of the patient's gastrointestinal tract in order to promote dissolution and the bioavailability of the compounds.
Pharmaceutically acceptable salts include those derived from pharmaceutically acceptable inorganic or organic bases and acids, where applicable. Suitable salts include those derived from alkali metals such as potassium and sodium, alkaline earth metals such as calcium, magnesium and ammonium salts, among numerous other acids and bases well known in the pharmaceutical art. Sodium and potassium salts are particularly preferred as neutralization salts of the phosphates according to the present invention.
[0175] The acids which are used to prepare the pharmaceutically acceptable acid addition salts of the aforementioned base compounds useful in this invention are those which form non-toxic acid addition salts, i.e., salts containing pharmacologically acceptable anions, such as the hydrochloride, hydrobromide, hydroiodide, nitrate, sulfate, bisulfate, phosphate, acid phosphate, acetate, lactate, citrate, acid citrate, tartrate, bitartrate, succinate, maleate, fumarate, gluconate, saccharate, benzoate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate and pamoate [i.e., 1,1'-methylene-bis-(2-hydroxy-3 naphthoate)]salts, among numerous others.
10176] Pharmaceutically acceptable base addition salts may also be used to produce pharmaceutically acceptable salt forms of the compounds or derivatives according to the present invention. The chemical bases that may be used as reagents to prepare pharmaceutically acceptable base salts of the present compounds that are acidic in nature are those that form non-toxic base salts with such compounds. Such non-toxic base salts include, but are not limited to those derived from such pharmacologically acceptable cations such as alkali metal cations (eg., potassium and sodium) and alkaline earth metal cations (eg, calcium, zinc and magnesium), ammonium or water-soluble amine addition salts such as N-methylglucamine-(meglumine), and the lower alkanolammonium and other base salts of pharmaceutically acceptable organic amines, among others.
[0177] Compositions [0178] In another aspect, the description provides compositions comprising compounds as described herein, including salts thereof, and a pharmaceutically acceptable carrier. In certain embodiments, the compositions are therapeutic or pharmaceutical compositions comprising an effective amount of a compound as described herein and a pharmaceutally acceptable carrier.
[0179] The amount of compound in a pharmaceutical composition of the instant invention that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host and disease treated, the particular mode of administration.
Generally, an amount between 0.1 mg/kg and 1000 mg/kg body weight/day of active ingredients is administered dependent upon potency of the agent. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50%
of the population) and the ED50 (the dose therapeutically effective in 50% of the population).
The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD50/ED50. Compounds that exhibit large therapeutic indices are preferred.
While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects. The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture.
Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography.
[0180] The compositions of the present invention may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers and may also be administered in controlled-release formulations. Pharmaceutically acceptable carriers that may be used in these pharmaceutical compositions include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as prolamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.
[0181] The active compound is included in the pharmaceutically acceptable carrier or diluent in an amount sufficient to deliver to a patient a therapeutically effective amount for the desired indication, without causing serious toxic effects in the patient treated. A preferred dose of the active compound for all of the herein-mentioned conditions is in the range from about 10 ng/kg to 300 mg/kg, preferably 0.1 to 100 mg/kg per day, more generally 0.5 to about 25 ing per kilogram body weight of the recipient/patient per day. A typical topical dosage will range from 0.01-5% wt/wt in a suitable carrier.

RG1, RG2, RG3 and RG4 are moieties with suitable reacting groups that would be necessary to enable the synthetic chemistry to connect intermediate A, intermediate L and intermediate V together into PROTAC compounds of Formula I
via covalent bond formation chemistries. These chemistries, depends on specific reacting groups, include but not limited to, amide formation, ester formation, carbamate formation, urea formation, ether formation, amine formation and various C-C, C=C bond formation. The stage 1 and stage 2 transformations in scheme 5 and scheme 6 may involve 1 or multiple synthetic steps. These are routine methods known in the art such as those methods disclosed in standard reference books such as the Compendium qf Organic Synthetic Methods, Vol. 1-VI (Wiley-lnterscience); or the Comprehensive Organic Transformations, by R.C. Larock (Wiley-lnterscience).
Unless otherwise indicated, the substituents in the schemes are defined as above.
Isolation and purification of the products is accomplished by standard procedures, which are known to a chemist of ordinary skill.
[0255]
In certain examples, for the chemistry described in schemes 3-6. RG is a moiety with a suitable nucleophile such as -OH and RG2 is a moiety with a suitable leaving group such as halogen, -OMs, or ¨0Ts. In a typical procedure, a RG1 containing intermediate is reacted with a RG2 containing intermediate in a suitable solvent. Suitable solvents include, but are not limited to, water, ethers such as THF, glyme, and the like; chlorinated solvents such as DCM, 1,2-dichloroethane (DCE) or CHCI3 and the like, toluene, benzene and the like, DMF, DMSO, MeCN. If desired, mixtures of these solvents are used. A base may be added to the reaction to facilitate the reaction. Suitable bases include, but are not limited to, Cs2CO3, K2CO3, and the like. The above process may be carried out at temperatures between about -78 C and about 150 C. Preferably, the reaction is carried out between about 20 C and about 120 C.
[0256] In another example, chemistry described in in schemes 3-6, RG3 is a moiety contains a ¨COOH group and RG4 is a moiety contains a suitable amine group. In a typical procedure, a RG3 containing intermediate is reacted with a RG4 containing intermediate in a suitable solvent in the presence of a suitable amide coupling reagent.
Suitable solvents include, but are not limited to, water, ethers such as THF, glyme, and the like;
chlorinated solvents such as DCM, 1,2-dichloroethane (DCE) or CHC13 and the like, toluene, benzene and the like, DMF, DMSO, MeCN. If desired, mixtures of these solvents are used. In this case, the preferred solvents are DMF or DCM. A suitable amide coupling reagent include, but are not limited to, DCC, EDC, HATU, HBTU, PyBOP and the like. A base is often added to the reaction. Suitable bases include, but are not limited to, TEA, DIPEA, and the like. The above process may be carried out at temperatures between about -78 C and about 150 C. Preferably, the reaction is carried out between about 0 C and about 100 C.
[0257] Although not explicitly shown in schemes 3-6, a chemist of ordinary skill would realize that during any of the synthetic sequences it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This can be achieved by means of conventional protecting groups, such as those described in T.W. Greene, Protective Groups in Organic Chemistry, John Wiley & Sons (1981); T.W. Greene and P.G.M. Wuts, Protective Groups in Organic Chemistry, John Wiley & Sons (1991), and T.W. Greene and P.G.M. Wuts, Protective Groups in Organic Chemistry, John Wiley & Sons, 1999, which are hereby incorporated by reference in their entireties.

The resulting solution was stirred at 0 C for 30 minutes, and then it was warmed up to room temperature and stirred at room temperature for 15 hours. A mixture of water/ice (1: 1, 50 mL) was added to the reaction, the resulting mixture was extracted with ethyl acetate (100 mL x 3). The organic layers were combined, washed with saturated aqueous solution of sodium chloride (20 mL x 2), dried over anhydrous sodium sulfate and then concentrated under reduced pressure to give a crude residue, which was purified by flash silica gel chromatography (eluent:

The resulting solution was then heated to 50 C
and stirred at this temperature for 2 hours. The bulk of organic solvent was removed under reduced pressure. To the remaining residue was added aqueous hydrogen chloride (1 M) to adjust the pH to -3. The resulting mixture was extracted with ethyl acetate (50 mL x 2), the organic layers were combined, washed with saturated aqueous solution of sodium chloride (20 mL x 2), dried over anhydrous sodium sulfate and then concentrated under reduced pressure followed by high vacuum pump to give BM (yield: 78%) as a yellow solid.
