For example, if a C.sub.6 aryl group, also called “phenyl” herein, is substituted with one additional substituent, one of ordinary skill in the art would understand that such a group has 4 open positions left on carbon atoms of the C.sub.6 aryl ring (6 initial positions, minus one at which the remainder of the compound of the present invention is attached to and an additional substituent, remaining 4 positions open). In such cases, the remaining 4 carbon atoms are each bound to one hydrogen atom to fill their valencies. Similarly, if a C.sub.6 aryl group in the present compounds is said to be “disubstituted,” one of ordinary skill in the art would understand it to mean that the C.sub.6 aryl has 3 carbon atoms remaining that are tmsubstituted. Those three tmsubstituted carbon atoms are each bound to one hydrogen atom to fill their valencies.

[0248] As used herein, the same symbol in different FORMULAE refers to a different definition, for example, the definition of R1 in FORMULA 1 is as defined with respect to FORMULA 1 and the definition of RI in FORMULA 6 is as defined with respect to FORMULA 6.

[0249] As used herein, when m (or n or o or p) is defined by a range, for example, “m is 0 to 15” or “m=0-3” mean that in is an integer from 0 to 15 (i.e. m is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15) or m is an integer from 0 to 3(i.e. m is 0, 1, 2, or 3) or is any integer in the defined range.

DETAILED DESCRIPTION

[0253] The present disclosure is based in part, on the discovery that novel heterobifunctional small molecules which degrade AKT and/or AKT mutant proteins are useful in the treatment of AKT-mediated diseases, particularly developmental and over-growth syndromes, cardiovascular disease, diabetes, inflammatory and autoimmune disorders, neurological disorders, and cancer, including but not limited to colon cancer, ovarian cancer, brain cancer, lung cancer, pancreatic cancer, breast cancer, prostate cancer, and gastric carcinoma. Successful strategies for selective degradationidisrupfion of the target protein induced by a bifunctional small molecule include recruiting an E3 ubiquitin ligase and mimicking protein misfolding with a hydrophobic tag (Buckley and Crews, 2014). The bifunctional molecules have three moieties: one E3-binder moiety that binds an E3 ubiquitin ligase; one targeted protein-binder moiety that binds the protein target of interest; and a linker moiety that connects the E3-binder and the targeted protein-binder moieties (Buckley and Crews, 2014). The induced proximity leads to selective ubiquitination of the target followed by its degradation at the proteasome. Several types of high affinity small-molecule E3 ligase ligands have been identified/developed: immunomodulatory drugs (IMiDs) such as thalidomide and pomalidomide, which bind cereblon (CRBN or CRL4CRBN), a component of a cullin-RING ubiquitin ligase (CRL) complex (Bondeson et al., 2015; Chamberlain et al., 2014; Fischer et al., 2014; Ito et al., 2010; Winter et al., 2015); and VHL-1, a hydroxyproline-containing ligand, which binds van Hippel-Lindau protein (VHL or CRL2VHL), a component of another CRL complex (Bondeson et al., 2015; Buckley et al., 2012a; Buckley et al., 2012b; Galdeano et al., 2014; Zengerle et al., 2015). This bifunctional molecule technology has been successfully applied to degradation of multiple targets (Bondeson et al., 2015; Buckley et al., 2015; Lai et al., 2016; Lu et al., 2015; Winter et al., 2015; Zengerle et al., 2015). Recently, peptidic VHL-recruiting bifunctional molecule has been reported (Henning et al., 2016). However, there are no reported small molecule-based bifunctional molecules that lead to the degradation of AKT or AKT mutant proteins. In addition, a hydrophobic tagging approach, which utilizes a bulky and hydrophobic adamantyl group, has been developed to mimic protein misfolding, leading to the degradation of the target protein by proteasome (Buckley and Crews, 2014). This approach has been successfully applied to selective degradation of the pseudokinase Her3 (Xie et al., 2014), but not to degradation of AKT or AKT mutant proteins.

[0254] As discussed in the following examples, this disclosure provides specific examples of novel AKT degraders/disruptors, and examines the effect of exemplary degraders/disruptors on reducing AKT protein levels, inhibiting/disrupting AKT activity, and inhibiting cancer cell proliferation. The results indicate that these novel small molecules can be beneficial in treating human disease, especially developmental and over-growth syndromes, cardiovascular disease, diabetes, inflammatory and autoimmune disorders, neurological disorders, and cancer, including but not limited to colon cancer, ovarian cancer, brain cancer, lung cancer, pancreatic cancer, breast cancer, prostate cancer, and gastric carcinoma.

[0255] A number of selective small-molecule AKT catalytic inhibitors, such as GSK690693 (Heerding et al., 2008), GSK2110183 (Dumble et al., 2014), GSK2141795 (Dumble et al., 2014)VD5363 (Addie et aL, 2013), GDC0068 (Blake et aL, 2012), MK-2206 (Hirai et al., 2010), and ARQ-092 (Yu et al., 2015) have been in clinical trials for treating ovarian cancer, fallopian tube cancer, peritoneal cancer, neuroendocrine tumor, acute myelogenous leukemia, lymphoma, gastric and gastroesophageal junction cancer, biliary cancer, non-small cell lung cancer, pancreatic cancer, nasopharyngeal carcinoma, adenoid cystic carcinoma, endometrial cancer, colorectal cancer, breast cancer, renal cell carcinoma, prostate, glioblastoma, gliosarcoma, chronic lymphocytic leukemia, melanoma (Pretre and Wicki, 2017). Despite effectiveness in preclinical animal models, the majority of these inhibitors lack efficacy in human patients (Manning and Toker, 2017).

[0256] Currently compounds targeting AKT generally focus on inhibition of its catalytic activity. In the present disclosure, a different approach is taken: to develop compounds that directly and selectively target not only the catalytic function of AKT, but also its protein level in cells. Strategies for inducing protein degradation include recruiting E3 ubiquitin ligases, mimicking protein misfolding with hydrophobic tags, and inhibiting chaperones. For example, a thalidomide-JQ1 bivalent compound has been used to hijack the cereblon E3 ligase, inducing highly selective BET protein degradation in vitro and in vivo and resulting in a demonstrated delay in leukemia progression in mice (Winter et aL, 2015). Similarly, BET protein degradation has also been induced via another E3 ligase, (Zengerle et al., 2015). Partial degradation of Her3 has been induced using an adamantane-modified compound (Xie et al., 2014). Such an approach, based on the use of bivalent small molecule compounds, permits more flexible regulation of protein levels in vitro and in vivo compared with techniques such as gene knockout or knockdown via RNA interference. Unlike gene knockout or knockdown, this chemical approach further provides an opportunity to study dose and time dependency in a disease model through varying the concentrations and frequencies of administration of the relevant compound.

[0257] This disclosure includes all stereoisomers, geometric isomers, tautomers and isotopes of the structures depicted and compounds named herein. This disclosure also includes compounds described herein, regardless of how they are prepared, e.g., synthetically, through biological process (e.g., metabolism or enzyme conversion), or a combination thereof.

Degraders

[0260] In some aspects, the present disclosure provides bivalent compounds, also referred to herein as degraders, comprising an AKT ligand (or targeting moiety) conjugated to a degradation tag. Linkage of the AKT ligand to the degradation tag can be direct, or indirect via a linker.

[0261] As used herein, the terms “serine threonine kinase (AKT) ligand” or “AKT ligand” or “AKT targeting moiety” are to be construed broadly, and encompass a wide variety of molecules ranging from small molecules to large proteins that associate with or bind to AKT. The AKT ligand or targeting moiety can be, for example, a small molecule compound (i.e., a molecule of molecular weight less than about 1.5 kilodaltons (kDa)), a peptide or polypeptide, nucleic acid or oligonucleotide, carbohydrate such as oligosaccharides, or an antibody or fragment thereof.

[0262] The AKT ligand or targeting moiety can be an AKT inhibitor (e.g., GSK690693 (1-leerding et al., 2008), GSK2110183 (Dumble et al., 2014), GSK2141795 (Dumble et al. 2014), AZD5363 (Addie et al., 2013), GDC0068 (Blake et al., 2012), MK-2206 (Hirai et al., 2010), and ARQ-092 (Yu et al., 2015), and analogs thereof), which is capable of interfering with the enzymatic activity of AKT, As used herein, an “inhibitor” refers to an agent that restrains, retards, or otherwise causes inhibition of a physiological, chemical or enzymatic action or function and causes a decrease in enzyme activity of at least 5%. An inhibitor can also or alternately refer to a drug, compound, or agent that prevents or reduces the expression, transcription, or translation of a gene or protein, An inhibitor can reduce or prevent the function of a protein, e.g., by binding to or activating/inactivating another protein or receptor,

[0263] Exemplary AKT ligands include, but are not limited to, the compounds listed below:

##STR00033## ##STR00034## ##STR00035## ##STR00036##

[0264] As used herein, the term “degradation/disruption tag” refers to a compound which associates with or binds to a ubiquitin ligase for recruitment of the corresponding ubiquitination machinery to AKT or induces AKT protein misfolding and subsequent degradation at the proteasorne or loss of function.

[0265] In some aspects, the degradation/disruption tags of the present disclosure include, e.g., pomalidomide (Fischer et al., 2014), thalidomide (Fischer et al., 2014), lenalidomide (Fischer et al., 2014), VH032 (Galdeano et al., 2014; Maniaci et al., 2017), adamantine (Xie et al., 2014), 1((4.4,5,5,5-pentalluoropentypsulfinypnonane (E. Wakeling, 1995), nutlin-3a (Vassilev et al., 2004), RG7112 (Vu et al., 2013), RG7338, AMG 232 (Sun et al., 2014), AA-115 (Aguilar et al., 2017), bestatin (Hiroyuki Suda et al., 1976), MV1 (Varfolomeev et al., 2007), LCL161 (Weisberg et al., 2010), and/or analogs thereof.

[0266] As used herein, a “linker” is a bond, molecule, or group of molecules that binds two separate entities to one another. Linkers provide for optimal spacing of the two entities. The term “linker” in some aspects refers to any agent or molecule that bridges the AKT ligand to the degradation/disruption tag. One of ordinary skill in the art recognizes that sites on the AKT ligand or the degradation/disruption tag, which are not necessary for the function of the bifunctional molecule of the present disclosure, are ideal sites for attaching a linker, provided that the linker, once attached to the conjugate of the present disclosures, does not interfere with the function of the bifunctional molecule, i.e., its ability to target AKT, and its ability to recruit a ubiquitin ligase.

[0267] The length of the linker of the bivalent compound can be adjusted to minimize the molecular weight of the disruptors/degraders and avoid the clash of the AKT ligand or targeting moiety with the ubiquitin ligase or induce AKT misfolding by the hydrophobic tag at the same time.

[0268] In some aspects, the degradation/disruption tags of the present disclosure include, for example, pomalidomide (Fischer et al., 2014), thalidomide (Fischer et al., 2014), lenalidomide (Fischer et al., 2014), VH032 (Galdeano et al., 2014; Maniaci et al., 2017), adamantine (Xie et al., 2014), 1-((4.4,5,5,5-pentafluoropentyl)sulfinyl)nonane (E,Wakeling, 1995), nutlin-3a (Vassilev et al., 2004), RG7112 (Vu et al., 2013), RG7338, AMG 232 (Sun et al., 2014), AA-115 (Aguilar et al., 2017), bestatin (Hiroyuki Suda et al., 1976), MV1 (Varfolomeev et al., 2007), LCL161 (Weisberg et al., 2010), and analogs thereof. The degradation/disruption tags can be attached to each portion of interest in the structure of an AKT ligand or targeting moiety (e.g., GSK690693 (Heerding et al., 2008), GSK2110183 (Durable et al., 2014), GSK2141795 (Dumble et al., 2014), AZD5363 (Addie et al., 2013), GDC0068 (Blake et al., 2012), MK-2206 (Hirai et al., 2010), and ARQ-092 (Yu et al., 2015)) with linkers of different types and lengths in order to generate effective bivalent compounds. In particular, attaching pomalidomide or VHL-1 to either portion of the molecule can recruit the cereblon E3 ligase to AKT.

[0269] The bivalent compounds disclosed herein can selectively affect AKT-mediated disease cells compared to WT (wild type) cells (i.e., an AKT degrader,/disruptor able to kill or inhibit the growth of an AKT-mediated disease cell while also having a relatively low ability to lyse or inhibit the growth of a WI cell), e.g., possess a GI.sub.50 for one or more AKT-mediated disease cells more than 1.5-fold lower, more than 2-fold lower, more than 2.5-fold lower, more than 3-fold lower, more than 4-fold lower, more than 5-fold lower, more than 6-fold lower, more than 7-fold lower, more than 8-fold lower, more than 9-fold lower, more than 10-fold lower, more than 15-fold lower, or more than 20-fold lower than its GI.sub.50 for one or more WT cells, e.g., WT cells of the same species and tissue type as the AKT-mediated disease cells.

[0270] Additional bivalent compounds (i.e., AKT degraders/disruptors) can be developed using the principles and methods disclosed herein. For example, other linkers, degradation/disruption tags, and AKT binding/inhibiting moieties (not limited to GSK690693 (Heerding et al., 2008), GSK2110183 (Dumble et al., 2014), GSK2141795 (Dwnble et al., 2014), AZD5363 (Addie et al., 2013), GDC0068 (Blake et al., 2012), MK-2206 (Hirai et al., 2010), and ARQ-092 (Yu et al., 2015)) can be synthesized and tested.

[0271] In some aspects, the AKT degraders/disruptors have the form “PI-Linker-EL”, as shown below:

##STR00037##

wherein PI (a ligand for a “protein of interest,” i.e., the protein to be degraded) comprises an AKT ligand (e.g., an AKT inhibitor), and EL (e.g., a ligand for an E3 ligase) comprises a degradation/disruption tag (e.g., E3 ligase ligand). Exemplary AKT ligands (PI), exemplary degradation/disruption tags (EL), and exemplary linkers (Linker) are illustrated below:

Synthesis and Testing of Bivalent Compounds

[0444] The binding affinity of novel synthesized bivalent compounds (i.e., AKT degraders/disruptors) can be assessed using standard biophysical assays known in the art (e.g., isothermal titration calorimetry (ITC)). Cellular assays can then be used to assess the bivalent compound's ability to induce AKT degradation and inhibit cancer cell proliferation. Besides evaluating a bivalent compound's induced changes in the protein expression of AKT or AKT mutant proteins, enzymatic activity can also be assessed. Assays suitable for use in any or all of these steps are known in the art, and include, e.g., Western blotting, quantitative mass spectrometry (MS) analysis, flow cytometry, enzymatic inhibition, ITC, SPR, cell growth inhibition and xenograft and PDX models. Suitable cell lines for use in any or all of these steps are known in the art and include, e.g., LNCaP cells (androgen-sensitive human prostate adenocarcinoma cells), PC3 (PC-3) cells (PTEN homozygous deletion mutant human prostate cancer cell lines), MCF7-neo/HER2 cells (PIK3CAE545K mutant stably expressing a HER2 transgene breast cancer cells), BT474M1. cells (PIK3CAK111N mutant and HER2-amplified human breast carcinoma), and IGROV-1 cells (PTENT319fsX1/Y155C and PIK3CA1069 Wovarian cancer cells), MDA-MB-468 cells (PTEN loss breast cancer cells), HCC.sub.1143 cells (Triple Negative Breast Cancer cells, TP53R248Q mutant), MDA-MB-231 (Triple Negative Breast Cancer cells), and U87MG cells (PTEN Loss Glioblastoma cells). Suitable mouse models for use in any or all of these steps are known in the art and include, e.g., PC3 prostate cancer model. MCF7-neo/HER2 breast cancer model, LNCaP prostate adenocarcinoma model, MDA-MB-468 breast cancer model, HCC.sub.1143 breast cancer model, and. TOV-21G.x1 ovarian cancer xenograft model.

[0445] By way of non-limiting example, detailed synthesis protocols are described in the Examples for specific exemplary AKT degraders/disruptors.

[0446] Pharmaceutically acceptable isotopic variations of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (substituting appropriate reagents with appropriate isotopic variations of those reagents). Specifically, an isotopic variation is a compound in which at least one atom is replaced by an atom having the same atomic number, but an atomic mass different from the atomic mass usually found in nature. Useful isotopes are known in the art and include, for example, isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine. Exemplary isotopes thus include, e.g., .sup.2H, .sup.3H, .sup.13C 14C, .sup.15N, .sup.17O, .sup.18O, .sup.32P, .sup.35S, .sup.18F, and .sup.36Cl.

[0447] Isotopic variations (e.g., isotopic variations containing .sup.2H) can provide therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements. In addition, certain isotopic variations (particularly those containing a radioactive isotope) can be used in drug or substrate tissue distribution studies. The radioactive isotopes tritium (.sup.3H) and carbon-14 ('.sup.4C) are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.

[0448] Pharmaceutically acceptable solvates of the compounds disclosed herein are contemplated. A solvate can be generated, e.g., by substituting a solvent used to crystallize a compound disclosed herein with an isotopic variation (e.g., D.sub.2O in place of H.sub.2O, D.sub.6-acetone in place of acetone, or d.sub.6-DMSO in place of DMSO).

[0449] Pharmaceutically acceptable fluorinated variations of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (substituting appropriate reagents with appropriate fluorinated variations of those reagents). Specifically, a fluorinated variation is a compound in which at least one hydrogen atom is replaced by a fluoro atom. Fluorinated variations can provide therapeutic advantages resulting from greater metabolic stability, e. increased in vivo half-life or reduced dosage requirements.

[0450] Specific exemplary AKT degraders/disruptors were characterized in various cells and mice (Examples 167-178. FIGS. 1-12), Bifunctional compounds XF038-165A, XF038-166A, XF038-176A, XF038-177A, XF042-162, XF042-168, XF042-170, XF048-1, XF048-2, XF048-3, XF048-4, XF048-5, XF048-7, XF048-8, XF050-5, XF050-7, XF050-16, XF050-17, XF050-18, XF050-19, XF050-20, XF050-21, XF050-30, XF050-31, XF050-32, XF050-33, XF050-98, XF050-133, XF056-93, XF050-143, XF050-144, XF050-145, XF050-167, XF056-33, XF056-34, XF056-35, and XF056-37, in particular were found to be effective in suppressing both AKT protein level and AKT activity in BT474 cells (FIGS. 1, 3, and 4). We further demonstrated that XF038-166A, XF042-162, XF042-170, XF050-21, and XF050-33 induced AKT degradation is time-dependent with 24 h being the time point for the most significant AKT degradation in BT474 cells (FIGS. 2 and 5). Using XF050-21, we showed that the observed AKT degradation can be rescued by pretreatment of the cells with VHL-1, MLN4924, MG132 and AZD5363 (FIG. 6). In FIG. 7, we compared the cell proliferation inhibition effects of AZD5363 and XF050-21. XF050-21 displayed better cell proliferation inhibition activity than AZD5363 in PC3 and MDA-MB-468 cells. In FIG. 8, XF050-21 showed better colony formation inhibition than AZD5363 in PC3, MDA-MB-468, HCC.sub.1143, and MDA-MB-231 cells. In FIG. 9, we showed that the combination treatment using an AKT degrader (XF050-21 or XF041-170) and a MTOR inhibitor (torin 1 or rapamycin) significantly reduced the AKT protein levels and AKT downstream signaling in BT474 cells. In mice, XF050-21-22 was bioavailable at 75 mg/kg via IP administration (FIG. 10). Additional bifunctional compounds were tested at 1 uM concentration in PC-3 cells. Compounds XF067-15, XF067-16, XF067-17, XF067-18, XF067-44, XF067-45, XF067-46, XF067-47, XF067-98, XF067-99, XF067-100, XF067-101, XF067-112 and XF067-113 were found to be effective in suppressing AKT protein level and AKT activity at 1 concentration in PC-3 cells (FIGS. 11 and 12).

[0480] The compounds and methods of this disclosure can be also used to treat diseases and conditions such as rheumatoid arthritis, osteoarthritis, Crohn's disease, angiofibroma, retinal vascularization, diabetic retinopathy, age-related macular degeneration, macular degeneration, multiple sclerosis, obesity, Alzheimer's disease, restenosis, autoimmune diseases, allergy, asthma, endometriosis, atherosclerosis, vein graft stenosis, peri-anastomatic prosthetic graft stenosis, prostate hyperplasia, chronic obstructive pulmonary disease, psoriasis, inhibition of neurological damage due to tissue repair, scar tissue formation, multiple sclerosis, inflammatory bowel disease, infections, particularly bacterial, viral, retroviral or parasitic infections, pulmonary disease, neoplasm, Parkinson's disease, transplant rejection, and septic shock,

[0481] The AKT-mediated disease can be a relapsed disease. The AKT-mediated disease can have been refractory to one or more previous treatments by different therapies.

[0482] As used herein, the term “preventing a disease” (e,g., preventing cancer) in a subject means for example, to stop the development of one or more symptoms of a disease in a subject before they occur or are detectable, e.g., by the patient or the patient's doctor. Preferably, the disease (e.g., cancer) does not develop at all, i.e., no symptoms of the disease are detectable. However, it can also result in delaying or slowing of the development of one or more symptoms of the disease. Alternatively, or in addition, it can result in the decreasing of the severity of one or more subsequently developed symptoms.

[0483] Specific dosage and treatment regimens for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient's disposition to the disease, condition or symptoms, and the judgment of the treating physician.

[0484] An effective amount can be administered in one or more administrations, applications or dosages. A therapeutically effective amount of a therapeutic compound (i.e., an effective dosage) depends on the therapeutic compounds selected. Moreover, treatment of a subject with a therapeutically effective amount of the compounds or compositions described herein can include a single treatment or a series of treatments. For example, effective amounts can be administered at least once. The compositions can be administered from one or more times per day to one or more times per week; including once every other day. The skilled artisan will appreciate that certain factors can influence the dosage and timing required to effectively treat a subject, including but not limited to the severity of the disease or disorder, previous treatments, the general health or age of the subject, and other diseases present. Following administration, the subject can be evaluated to detect, assess, or determine their level of disease. In some instances, treatment can continue until a change (e.g., reduction) in the level of disease in the subject is detected. Upon improvement of a patient's condition (e.g., a change (e.g., decrease) in the level of disease in the subject), a maintenance dose of a compound, or composition disclosed herein can be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, can be reduced, e.g., as a function of the symptoms, to a level at which the improved condition is retained. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.

[0485] The present disclosure is also described and demonstrated by way of the following examples. However, the use of these and other examples anywhere in the specification is illustrative only and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to any particular preferred embodiment or aspect described herein. Indeed, many modifications and variations may be apparent to those skilled in the art upon reading this specification, and such variations can be made without departing from the invention in spirit or in scope. The invention is therefore to be limited only by the terms of the appended claims along with the full scope of equivalents to which those claims are entitled.

Synthesis of Intermediate 13

[0757] ##STR00204##

[0758] The intermediate 10 was synthesized following a known procedure (Heerding et al., 2008). To the suspension of intermediate 10 (119 mg×3, 0.5 mmol) and methyl-4-oxobutanonate (58 mg×3, 0.5 mmol) in 5 mL of DCM was added sodium triacetoxyborohydride (211 mg×3, 1.0 mmol) in three times. Once the reaction mixture became clear solution, saturated NaHCO.sub.3 solution was added to quench the reaction. After the organic phase was separated, the aqueous phase was extracted with DCM (10 mL×3). The combined organic layers were dried over Na.sub.2SO.sub.4, filtered and concentrated. The resulting residue was dissolved in DCM (15 mL). To the resulting solution were added di-tert-butyl decarbonate (272 mg, 1.25 mmol) and triethylamine (188 mg, 1.86 mmol). The reaction was stirred for 30 min, before the reaction mixture was concentrated. The resulting residue was purified by silica gel column (Hexane/EA=1:3) to afford intermediate 11 as yellow solid (178 mg, 53%). ESI m/z 548.8 [M+H].sup.+. Intermediate 11 (178 mg, 0.34 mmol) was dissolved in DMSO (5 mL) in a pressure vessel. To the resulting solution were added 2-methylbut-3-yn-2-ol (371 μL, 4.1 mmol), zinc powder (68 mg, 1.02 mmol), NaI (16 mg, 0.11 mmol), DBU (153 μL, 1.02 mmol), and triethylamine (207 μL, 1.02 mmol). The reaction was degassed for 5 min, before the catalyst Pd(PPh.sub.3).sub.4 (40 mg, 10 mol %) was added. The reaction vessel was purged with nitrogen, sealed and heated to 80° C. for 1 h. The reaction was quenched by pouring into saturated NH.sub.4Cl. The aqueous layer was extracted with ethyl acetate. The combined organic extracts were dried over Na.sub.2SO.sub.4, filtered, and concentrated under reduced pressure to give the intermediate 12, which was used in the next step without further purification. The intermediate 12 (146 mg, 0.25 mmol) was dissolved in methanol (5 mL). To the resulting solution was added NaOH (0.5 inL, 3 N). The reaction was heated to 60° C., for 1 h, before the reaction mixture was concentrated. The resulting residue was purified by preparative HPLC (10%-100% methanol/0.1% TFA in H.sub.2O) to afford Intermediate 13 as white solid in TFA salt form (128.3 mg, 90%). 1H NMR (500 MHz, DMSO-d.sub.6) δ 8.15 (s, 1H), 7.03 (s, 2H), 4.93-4.74 (m, 2H), 4.40-4.26 (m, 2H), 3.39 (t, J=7.1 Hz, 2H), 3.22 (t, J=7.2 Hz, 2H), 2.21 (t, J=7.2 11z, 2H), 2.13-2.02 (m, 2H), 1.82-1.69 (m, 2H) 1.47 (t, J=7.0 Hz, 3H), 1.41-1.30 (m, 15H).

Materials And Methods:

General Chemistry Methods

[0833] HPLC spectra for all compounds were acquired using an Agilent 1200 Series system with DAD detector. Chromatography was performed on a 2.1×150 mm Zorbax 3005B-C.sub.18 5 μm column with water containing 0.1% formic acid as solvent A and acetonitrile containing 0.1% formic acid as solvent B at a flow rate of 0.4 ml/min. The gradient program was as follows: 1% B (0-1 min), 1-99% B (1-4 min), and 99% B (4-8 min). High-resolution mass spectra (HRMS) data were acquired in positive ion mode using an Agilent G1969A API-TOF with an electrospray ionization (ESI) source. Nuclear Magnetic Resonance (NMR) spectra were acquired on a Bruker DRX-600 spectrometer with 600 MHz for proton (.sup.1H NMR) and 150 MHz for carbon (.sup.13C NMR); chemical shifts are reported in (δ). Preparative HPLC was performed on Agilent Prep 1200 series with UV detector set to 254 nm. Samples were injected onto a Phenomenex Luna 250×30 mm, 5 μm, C.sub.18 column at room temperature. The flow rate was 40 ml/min. A linear gradient was used with 10% (or 50%) of MeOH (A) in H.sub.2O (with 0.1% TFA) (B) to 100% of MeOH (A). HPLC was used to establish the purity of target compounds. All final compounds had >95% purity using the HPLC methods described above.

Cell Culture and Treatment

[0834] PC-3, U87MG, HCC.sub.1143, MDA-MB-231, MDA-MB-468, BT474 and MCF-7 cell lines were purchased from ATCC. Cell lines were regularly tested in the lab for mycoplasma. All cells were cultured at 37° C. and 5% CO2. PC-3, U87MG, MDA-MB-231, MCF-7 and BT474 cells were cultured in 1× DMEM (Coming, 10-013-CV) with 10% fetal bovine serum (Atlanta Biologicals S11150) and 1× Penicillin/Streptomycin. HCC1143 cells were cultured in RPMI (Corning, 10-040-CV) medium with 10% fetal bovine serum (Atlanta Biologicals S11150) and1×0 Penicillin/Streptomycin, Cells were split using 0.05% or 0.25% trypsin (Corning 25-051-Cl or 25-053-Cl, respectively) before they reached full confluence and media was changed every 3-4 days. Cells were treated with compounds individually at different concentrations for 24 hrs. Cells were treated with DMSO, VHL, or PML alone as controls.

Immunoblotting

[0835] Cells were lysed in 2× sample buffer (25 mM Tris-HCl at pH 6.8, 10% βME, 2% SDS, 20% glycerol, 0.05% Bromophenol Blue, 8 M urea). Protein lysates were loaded into 4-12% Bis-Tris gels and resolved by electrophoresis. Samples were then blotted on PVDF membrane (Millipore IPVH00010) using the wet transfer technique (Invitrogen). Membranes were blocked in 5% milk-TBST for 1 hour, washed in TBST for 10 min, and incubated in primary antibody in 5% milk-TBST or 5% BSA-TBST at 4° C., for 16 h. Membranes were rinsed (3×6 min) in TBST and incubated in horseradish peroxidase-conjugated secondary antibodies in 5% milk-TBST for I hour and rinsed again in TBST (3×6 min). Membranes were visualized using the chemiluminescence system (Thermo 34080, 37075) on autoradiography film (Denville E3018). Primary Antibodies: β-actin (Sigma A5316), p-AKT (Ser473 CST-9721), total AKT (CST-9272), p-S6 (Ser240/244, CST-5364), p-PRAS40 (Thr246, CST-2997). Secondary Antibodies: Mouse (Thermo 31432), Rabbit (Thermo 31460).

Cell Viability Assay

[0836] Cells were cultured for 12-17 days in the presence of different compounds. Media with compound was replenished every two days. At the end of the experiment, media was aspirated and viable cells were stained with 0.5% crystal violet dye.

Proliferation and Apoptosis Assays

[0837] Experiments were carried out irr 96-well plates in triplicates. A total of 1-3 >10.sup.3 cells per well were grown in the presence of 1 μM of AZD5363 (Selleckchem), 1 μM of selected degrader compounds. Cells were then monitored for 3-4 days using the IncuCyte live cell imaging system (Essen BioScience, Ann Arbor, Mich., USA), which was placed in a cell culture incubator operated at 37° C. and 5% CO.sub.2. Cell confluence was determined using calculations derived from phase-contrast images. For measurement of cell death DRAQ7 (Cell Signaling #7406) at 1.5 μM was included in the medium and apoptotic red counts were measured in IncuCyte™ FLR automated incubator microscope.

Xenograft Studies

[0838] Thirty male immunocompromised nuinu mice (The Jackson Laboratory) was engrafted with PC-3 human prostate cancer cells that have never been passed through animals and was used under blood-born pathogen laboratory procedures, After tumor volumes reach ˜100 mm.sup.3, 3 treatment arms (10 animals per group) were administrated with vehicle control, AZD5363, or a selected degrader compound daily for 3-4 weeks via intraperitoneal (IP) injections. Tumor volume was calculated as follows: tumor size (mm.sup.3) (longer measurement×shorter measurement.sup.2)×0.5. Tumor sizes were recorded every other day over the course of the studies. Engraftment and monitoring of tumor growth and toxicity in mice were be performed. Treatments would be discontinued if toxicity or distress is encountered, All procedures involving mice and experimental protocols (LA13-00024) were approved by the Institutional Animal Care and Use Committee (IACUC) of Icahn School of Medicine at Mount Sinai (ISMMS).

Immunohistochemistry

[0839] Paraffin sections were dewaxed as previously described. If necessary, antigen retrieval was performed, typically, the sections were boiled in 0.01M sodium citrate, pH 6.0, 0.05% Tween-20 twice for 10 min, and then cooled at room temperature for 20 min. After that, the sections were washed with dd H.sub.2O for 3 times of 5 min each and then washed with PBS for 5 min. HRP conjugated secondary antibody was used to detect the signal. Endogenous HRP was blocked with 3% H.sub.2O in PBS or methanol for 10 min. Then the slide was washed in PBS for 3 times of 5 mins each. At this time, the section on slide was circled with a PAP pen. For cryosections, the sections were warmed from −80° C. freezer to room temperature and dried at room temperature for 30 mins or 15 mins at 50° C. Then sections were fixed in ice-cold acetone for 5 min on ice, and then air dried at room temperature for 30 mins, followed by washing with 1× PBS for 5 minsoAfterwards, the endogenous HRP was blocked with 3% H.sub.2O.sub.2 if necessary. The sections were washed again with PBS for 3 times of 5 mins each before circled with a PAP pen.

Statistics

[0840] No statistical methods were used to determine sample size, and experiments were not randomized. The experimenters were not blinded. Aside from traditional Mann-Whitney (non-parametric), SpeafliIan correlation test (non-parametric), student t-tests (parametric) to compare two data sets, and Chi-squared test (non-parametric), parametric statistical methods were used in order to make appropriate multiple comparisons of repeated measures of data (following 1-way or 2-way ANOVA). Graphpad Prism was used to make these simple predetermined statistical comparisons. Tukey's Multiple Comparisons Correction: Used for making all possible pairwise comparisons in a data set. Dunnett's Multiple Comparisons Correction: Used for comparing all samples to a control sample, but not for comparing the non-control samples to one another. Sidak's Multiple Comparisons Correction: Used when specific multiple comparisons are pre-selected. Fischer's Exact Test: Used to analyze items in a contingency table.
