Abstract
Description
Technical Field
[0001] The present disclosure relates to a bifunctional compound and a pharmaceutical composition comprising the bifunctional compound, as well as a method for treating androgen receptor-related diseases by administering the bifunctional compound. Background Art
[0002] Protein-protein interactions are not easy to target with small molecules, because the contact area of the protein is large, and the shallow groove or flat interface thereon may be related to the interaction. On the other hand, it has been shown that the pathogenic protein is finally degraded by the 26S proteasome system by tagging the pathogenic protein with ubiquitin, and such a therapeutic tool (modality) can widely and comprehensively eliminate the cause of the disease (Sun et al., Signal Transduct. Target Ther. 2019, 4: 64). In addition to E1 enzymes and E2 enzymes, E3 ubiquitin ligases (also referred to as E3 ligases) and their substrate recognition proteins can also make the ubiquitination of the substrate specific, and these components are very important in order to make the target protein substrate specifically and optionally degraded. Recent developments in target protein degradation have shown that E3 ligases such as cereblon (CRBN) E3 ligase, von Hippel-Lindau disease tumor suppressor (VHL) E3 ligase, mouse double minute 2 protein (MDM2) E3 ligase, and cell inhibitor of apoptosis protein (cIAP) E3 ligase have been successfully applied to the design of small molecule protein degradation drugs. These molecules may become candidates for treatment (Wang et al., Acta Pharm Sin B. 2020 Feb; 10(2): 207-238).
[0003] One E3 ligase with therapeutic potential is cerebellin E3 ligase, which is a protein encoded by the CRBN gene in humans. CRBN's orthologs are highly conserved from plants to humans. Cerebellin forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A) and Regulator of Cullins 1 (ROC 1). This complex ubiquitinates many other proteins (Vriend et al., Front Mol Biosci. 2018, 5: 19).
[0004] The androgen receptor (AR) is a member of the nuclear hormone receptor family and is activated by androgens (such as testosterone and dihydrotestosterone). When bound to androgens, AR translocates into the cell nucleus, where it acts as a transcription factor to promote the expression of genes responsible for male sexual characteristics. In addition to being responsible for the development of male sexual characteristics, AR also drives the growth and survival of prostate cancer cells (Salami et al., Commun. Biol. 2018, 1:100).
[0005] Inhibiting AR signaling is a common strategy in the treatment of prostate cancer. Prostate cancer is the second most commonly diagnosed cancer and ranks fifth among the causes of death in men worldwide. Most men with local or regional prostate cancer have a 5-year survival rate of nearly 100%, while men diagnosed with prostate cancer that has spread to other parts of the body have a 5-year survival rate of 31%. According to GLOBOCAN estimates, there were 1.41 million new cases and 375,000 deaths reported worldwide for prostate cancer in 2020. For decades, androgen deprivation therapy (ADT) has been the standard treatment for prostate cancer, which is performed by surgery or chemical castration. However, castration-resistant prostate cancer will eventually develop, and although serum testosterone is only sub-castration concentrations, tumor cell proliferation will be restored. With the approval of second-generation anti-androgen drugs, such as abiraterone acetate (ABI), enzalutamide (ENZ), and the recently approved apalutamide (APA) and darolutamide (DARO), the overall survival rate of patients with castration-resistant prostate cancer (CRPC) has improved. However, as is common in cancer chemotherapy, drug resistant escape mutations will eventually occur during the course of the disease (Zhao et al., Mol Cancer Ther. 2020, 19 (8): 1708-1718). In addition, androgens and AR have also been found to be associated with many skin diseases, such as androgeneticalopecia, acne, hirsutism, atopic dermatitis, etc. A significant amount of sex hormones are synthesized in the skin, and androgens affect hair growth, epidermal barrier homeostasis, wound healing, sebaceous gland growth, differentiation, etc. Antiandrogen drugs such as clascoterone, cyproterone acetate and flutamide are now used to treat these skin diseases.Androgen and AR concentrations may play an important role in the development of these AR signaling-related diseases (Zhou et al., Journal of Biosciences and Medicines 2022, 10: 180-200).
[0006] The present disclosure provides an alternative, which is to treat AR-mediated or AR-related diseases (disease) or abnormalities (disorder) by proteolysis targeting chimeric (PROTAC) bifunctional compounds. Related patent applications for PROTAC have been disclosed in WO2018071606, WO2018144649 and WO2021143816. However, there is still a need for compounds with better efficacy in treating androgen receptor-related diseases or abnormalities. Summary of the invention

[0148] In some embodiments, the pharmaceutical compositions of the present disclosure further comprise a second therapeutic agent.
[0149] In some embodiments, the androgen receptor-related disease is an androgen receptor-related cancer or an androgen receptor-related skin disease.
[0150] In some embodiments, the androgen receptor-related cancer is breast cancer or prostate cancer. In some embodiments, the cancer is breast cancer. In some embodiments, the cancer is prostate cancer. In some embodiments, the prostate cancer is castration-resistant prostate cancer.
[0151] In some embodiments, the androgen receptor-associated skin disease is androgenic alopecia, acne, hidradenitis suppurativa, hirsutism, or atopic dermatitis.
[0152] In some embodiments, the method of treating an androgen receptor-related disease further comprises administering an effective amount of a second therapeutic agent.
[0153] In some embodiments, the second therapeutic agent may be an androgen receptor inhibitor. An example of the androgen receptor inhibitor may be enzalutamide.
[0154] In some specific embodiments, the second therapeutic agent may be an antitumor agent known in the art. Examples of known antitumor agents include docetaxel, flutamide, goserelin acetate, leuprolide acetate, colchicine, leuprolide acetate, mitoxantrone hydrochloride, 5-fluorouracil and olaparib. Examples include one or more cyclophosphamide, mitomycin C, etc.

Examples of known anti-tumor agents include Clascoterone, ASC-J9, Spironolactone, Flutamide, Finasteride, Dutasteride, Cyproterone acetate, Pyrilutamide, Minoxidil, Ketoconazole, etc.
[0156] When used in this specification and claims, the articles "a" and "an" refer to one or more than one (ie, at least one) of the grammatical objects of the article unless the context clearly indicates otherwise. For example, "a component" means one component or more than one component.
[0157] When used in this specification and claims, the word "and / or" should be understood to mean "either or both" of the components so connected, that is, in some cases, the components are present together; and in some cases, the components are present separately. Multiple components listed with "and / or" should be interpreted in the same way, that is, "one or more" of the multiple components so connected. Other components other than the components specifically defined by the "and / or" clause may optionally exist, whether related or unrelated to those specifically defined components. Therefore, as a non-limiting example, when "A and / or B" is used with an open term such as "comprising", it may refer to only A (optionally including components other than B) in one specific embodiment; it may refer to only B (optionally including components other than A) in another specific embodiment; it may refer to both A and B (optionally including other components) in yet another specific embodiment, etc.
[0158] When used in this specification and claims, "or" should be understood to have the same meaning as "and / or" as defined above. For example, when separating items in a list, "or" or "and / or" should be interpreted as inclusive, i.e., including at least one of the multiple components or components in the list, but also including more than one component, and optionally including additional items not listed. Only when the words clearly indicate the opposite meaning, such as "only one of" or "exactly one of", or when "consisting of" is used in the claims, it will refer to including exactly one of the multiple components or components in the list. Generally speaking, when there is an exclusive term such as "either", "one of", "only one of" or "exactly one of", the word "or" used in this article should only be interpreted as referring to exclusive alternative items (i.e., "one or the other, but not both".
[0159] In the claims and the foregoing specification, all conjunctions such as "comprise," "include," "carry," "have," "contain," "involve," "hold," "composed of," and the like are to be understood as open-ended, that is, meaning including but not limited to. Only the conjunctions "consisting of" and "consisting essentially of" shall be closed or semi-closed conjunctions, respectively, as provided in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
[0160] When used in this specification and claims, the term "at least one" referring to a list of one or more components should be understood to mean at least one component selected from any one or more components in the list of components, but does not necessarily include at least one component of each and every component specifically listed in the list of components, and does not exclude any combination of components in the list of components. This definition also allows components other than the components specifically defined in the list of components referred to by the term "at least one" to optionally exist, whether related or unrelated to those specifically defined components. Therefore, as a non-limiting example, "at least one of A and B" (or equivalently "at least one of A or B", or equivalently "at least one of A and / or B") may refer to at least one, and optionally more than one A, without B (and optionally including components other than B) in one specific embodiment; and may refer to at least one, and optionally more than one B, without A (and optionally including components other than A) in another specific embodiment; and may refer to at least one, and optionally more than one A, and at least one, and optionally more than one B (and optionally including other components), etc. in another specific embodiment.
[0161] It should also be understood that in some of the methods described herein that include more than one step or action, unless otherwise specified, the order of those steps or actions in the method are not necessarily limited to the order of those steps or actions in the method described.
[0162] The term "effective" may mean, but is in no way limited to, an amount / dose that can achieve or is sufficient to prevent, inhibit the occurrence, alleviate, delay or treat (relieve symptoms to a certain extent, preferably all) the symptoms of a condition, disorder or disease state in a subject who needs such treatment or is receiving such treatment when the active pharmaceutical ingredient is used for the intended use in the context. The term "effective" encompasses all other effective amount or effective concentration terms, such as "effective amount / dose", "pharmaceutically effective amount / dose" or "therapeutically effective amount / dose" otherwise described or used in this application.
[0163] The effective amount depends on the type and severity of the disease, the composition used, the route of administration, the species of mammal to be treated, the physical characteristics of the particular mammal under consideration, and the concomitant drugs and other factors that can be recognized by those skilled in the art of medicine. The exact amount can be determined by those skilled in the art by conventional techniques (e.g., see 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).
[0164] The terms "pharmaceutically acceptable" or "pharmaceutically acceptable" may mean, but are in no way limited to, entities and compositions that do not produce adverse, allergic or other untoward reactions when administered to an animal or a human as desired.
[0165] The term "pharmaceutically acceptable carrier" or "pharmaceutically acceptable carrier" may 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, which are compatible with the administration of the pharmaceutical. Suitable carriers are described in the latest edition of Remington's Pharmaceutical Sciences, a standard reference text in this field, incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, Ringer'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 pharmaceutical active ingredients is well known in the art. Unless any conventional media or agent is incompatible with the active compound, its use in the composition should be considered. Supplementary active compounds may also be incorporated into the composition.
[0166] Unless otherwise indicated, the term "compound" as used herein refers to any specific chemical compound disclosed herein, and includes tautomers, regioisomers, geometric isomers thereof; where applicable, stereoisomers, including optical isomers (enantiomers) and other stereoisomers (diastereomers); where applicable, pharmaceutically acceptable salts and derivatives thereof (including prodrug forms). In its use in the context, the term compound generally refers to a single compound, but may also include other compounds, such as stereoisomers, regioisomers and / or optical isomers (including racemic mixtures), as well as specific enantiomers or enantiomerically enriched mixtures of the disclosed compounds. In this context, the term also refers to prodrug forms of compounds that are modified to facilitate administration and delivery of the compound to an active site. It should be noted that in describing the compounds herein, a number of substituents and associated variations are specifically described with respect thereto.
[0167] It will be understood by those skilled in the art that the molecules described herein are stable compounds as described below. When double bonds and single bonds are used, they are represented or understood within the context of the compound being described and according to the well-known rules of valence interactions.
[0168] As used herein, "alkoxy" refers to an alkyl group having a single bond to oxygen; for example, methoxy (-O-CH3) and ethoxy (-O-CH2CH3).
[0169] As used herein, "derivatives" may refer to compositions directly formed from natural compounds by modification or by partial substitution. As used herein, "analogs" may refer to compositions having structures similar to, but not identical to, natural compounds.
[0170] The term "ubiquitin ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to specific substrate proteins, targeting them for degradation. For example, the cerebellum protein E3 ubiquitin ligase, when present alone or in combination with an E2 ubiquitin-conjugating enzyme, attaches ubiquitin to a lysine on a target protein, which is then targeted to a specific substrate protein for degradation by the proteasome. Thus, E3 ubiquitin ligases, when present alone or in a complex with an E2 ubiquitin conjugating enzyme, are responsible for the transfer of ubiquitin to a target protein. In general, ubiquitin ligases involve polyubiquitination, whereby a second ubiquitin is attached to the first; a third to the second, and so on. Polyubiquitination marks a protein for degradation by the proteasome. However, some ubiquitination events are defined as mono-ubiquitination, where only a single ubiquitin is added to a substrate molecule by the ubiquitin ligase. Monoubiquitinated proteins are not targeted for degradation by the proteasome, but may change their cellular location or function; for example, by binding to other proteins with domains that can bind ubiquitin. Further, E3 ubiquitin ligases promote the formation of polyubiquitin chains through lysine residues on ubiquitin. Lys48-linked chains are the main type of polyubiquitination, which can target proteins to the proteasome for degradation.
[0171] The term "patient" or "subject" is used throughout the specification to describe a cell, tissue or animal, preferably a mammal, such as a human or a domesticated animal, to which the compositions of the present disclosure are provided for treatment (including prophylactic treatment). For a specific treatment for an infection, disorder or disease state in a specific animal, such as a human patient, the term "patient" refers to a specific animal, including a domestic animal such as a dog or cat, or a farm animal such as a horse, a cow, a sheep, etc. Unless otherwise indicated or implied in the context of the term, in the present disclosure, the term "patient" generally refers to a human patient.
[0172] It should be understood that in all examples disclosed herein, the description of an integer range for any variable describes the range of the variable, all individual numbers within the range, and all possible subranges. For example, the description that n is an integer from 0 to 4 describes 0, 1, 2, 3, and 4 as independently selectable values within the range. In addition, the description that n is an integer from 0 to 4 also describes its individual and all subranges, where n is individually 0 to 4, 0 to 3, 0 to 2, 0 to 1, 1 to 4, 1 to 3, 1 to 2, 2 to 4, 2 to 3, and 3 to 4. In addition, the term "C 1-6 "Alkyl" refers to an alkyl group having 1 to 6 carbons.

[0197] Intermediate IA was first prepared from commercially available 3-benzyloxy-aniline by the following route:
[0198] Synthesis Flowchart 1
[0199]
[0200] Palladium acetate (Pd(OAc)2) (1.13 g, 10 mol%) was added to a vessel purged with air, which contained a solution of 3-benzyloxy-aniline (10 g, 50.1 mmol), dimethyl acetylenedicarboxylate (5.86 mL, 47.6 mmol) and dimethylacetamide (DMA) / pivalic acid (PivOH) (4:1 v / v; 100 mL). The reaction mixture was gradually heated to 120°C for 8 hours. After the reaction was completed, the solution was cooled to room temperature, diluted with ethyl acetate (200 mL), washed with water (3×50 mL) and brine (50 mL), dried over magnesium sulfate (MgSO4), filtered, and evaporated in vacuo to obtain a crude product. The crude product was purified by column chromatography using silica gel (KM3 SCIENTIFIC CORP., particle size 45-75 μm) with an eluent (n-hexane: ethyl acetate = 5: 1) to obtain 6-benzyloxy-1H-indole-2,3-dicarboxylic acid dimethyl ester I-a1 (8.4 g, 54%) as a brown solid.
[0201] An ice-cold solution of 6-benzyloxy-1H-indole-2,3-dicarboxylic acid dimethyl ester I-a1 (3.0 g, 8.84 mmol) in N,N-dimethylformamide (DMF) (15 mL) was treated with 60% sodium hydride (NaH) (0.53 g, 13.3 mmol) and iodomethane (0.82 mL, 13.3 mmol) and then warmed to room temperature. After 1 hour, the reaction mixture was partitioned between dichloromethane (DCM) (60 mL) and saturated aqueous ammonium chloride (NH4Cl) (20 mL). The combined organic layers were collected, washed with water (3×20 mL) and brine (20 mL), then dried over MgSO4, filtered and concentrated to give a crude product. The crude product was purified by column chromatography using silica gel (KM3 SCIENTIFIC CORP., particle size 45-75 μm) and an eluent (n-hexane: ethyl acetate = 3:1) to obtain a brown solid I-a2 (2.7 g, 87%).
[0202] Palladium on carbon (Pd / C) (0.5 g) was added to a methanol (MeOH) solution (150 mL) containing 6-benzyloxy-1-methyl-1H-indole-2,3-dicarboxylic acid dimethyl ester) I-a2 (5.0 g) and stirred for 2 hours under a hydrogen atmosphere. After the reaction was completed, the mixture was passed through a Celite pad and rinsed with ethyl acetate (10 mL), and the organic solvent was collected and removed using a rotor to obtain an intermediate I-a3 (3.72 g, 100%).
[0203] To a stirred solution of 6-hydroxy-1-methyl-1H-indole-2,3-dicarboxylic acid dimethyl ester I-a3 (2.85 g, 10.83 mmol, 1.0 eq) in DCM (60 mL) was added N,N-diisopropylethylamine (DIPEA) (5.6 mL, 32.49 mmol, 3 eq) at 0°C and the mixture was stirred at the same temperature for 10 minutes. Trifluoromethanesulfonic anhydride (Tf2O) (2.9 mL, 16.25 mmol, 1.5 eq) was added dropwise to the reaction and the resulting mixture was stirred at 0°C for 1 hour. The reaction was diluted with DCM (40 mL) and washed with saturated sodium bicarbonate (NaHCO3) (10 mL), saturated NH4Cl (10 mL), water and brine. The organic layer was dried over MgSO4, filtered and concentrated to give a dark brown oil. The dark brown oil was purified by column chromatography using silica gel (KM3 SCIENTIFIC CORP., particle size 45-75 μm) eluted with 10% ethyl acetate in n-hexane to give the title compound as pure product I-a4 (3.68 g, 86%).
[0204] To a stirred toluene solution (20 mL) containing 1-methyl-6-trifluoromethanesulfonyloxy-1H-indole-2,3-dicarboxylic acid dimethyl ester I-a4 (0.77 g, 1.94 mmol, 1.0 eq), tert-butyl piperazine-1-carboxylate (1.08 g, 5.82 mmol, 3.0 eq), 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (XPhos) (0.18 g, 20 mol%) and cesium carbonate (Cs2CO3) (1.9 g, 5.82 mmol, 3 eq) were added. The mixture was degassed with nitrogen (N2) for 10 minutes, and Pd(OAc)2 (0.087 g, 20 mol%) was added to the mixture. The resulting mixture was stirred at 80°C for 17 hours until no starting material remained. The reaction was cooled to room temperature, diluted with ethyl acetate (30 mL) and water (10 mL), and the layers were separated. The aqueous layer was extracted with ethyl acetate (30 mL), and the combined organic layers were washed with brine (20 mL), dried over MgSO4, filtered and concentrated to give a crude material. The crude material was purified by column chromatography using silica gel (KM3 SCIENTIFIC CORP., particle size 45-75 μm) eluted with 25% ethyl acetate in n-hexane to give the title compound, which was pure product I-a5 (0.72 g, 86%).
[0205] I-a5 (0.65 g, 1.51 mmol) was treated with NaOH (0.6 g, 15.1 mmol) in ethanol (EtOH) (30 mL) and heated to reflux (85°C bath temperature). After 4 hours, the reaction mixture was cooled to ambient temperature, the excess EtOH was removed, diluted with ethyl acetate (30 mL) and acidified to pH 3 with 1 M hydrochloric acid (HCl), and the layers were separated. The aqueous layer was then extracted with ethyl acetate (30 mL), and the combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated to give a white solid. The white solid was then mixed with acetic anhydride (Ac2O) (5 mL) and heated to 140°C. After 2 hours, a mono-ester was found by liquid chromatography mass spectrometry (LC-MASS), and the reaction mixture was cooled to ambient temperature. The excess Ac2O was then removed, and anhydrous toluene (5 mL) was added, mixed and concentrated. This yielded the residue I-a6 which was used without further purification.
