Abstract
Description
[0001] Cross-reference to related applications
[0002] This application claims priority to and the benefit of U.S. Provisional Application No. 63 / 437,994, filed on January 9, 2023, and U.S. Provisional Application No. 63 / 618,208, filed on January 5, 2024, which are incorporated by reference in their entirety for all purposes. Technical Field
[0003] The present disclosure provides compounds comprising a target protein binding portion and an E3 ubiquitin ligase binding portion, and related methods of using these compounds. The compounds can be used as modulators targeting ubiquitination, such as B-cell lymphoma 6 protein (BCL6), which are degraded by the compounds of the present disclosure. Background Art
[0004] Most small molecule drugs bind enzymes or receptors in a tight and well-defined pocket. On the other hand, because the contact surface involved in protein-protein interactions is large and the grooves are shallow or the interface is flat, it is notorious that protein-protein interactions are difficult to target using small molecules. E3 ubiquitin ligases (hundreds of which are known in humans) impart substrate specificity for ubiquitination, and therefore, due to their specificity for certain protein substrates, are more attractive therapeutic targets than general proteasome inhibitors. The development of E3 ligase ligands has proven challenging, in part due to the fact that they must destroy protein-protein interactions. However, recent developments have provided specific ligands that bind to these ligases. For example, since the discovery of the first small molecule E3 ligase inhibitor, nutlin, other compounds targeting E3 ligases have been reported, but this field is still underdeveloped.
[0005] Cerebellin is a protein encoded by the CRBN gene in humans. CRBN orthologs are highly conserved from plants to humans, highlighting its physiological importance. Cerebellin forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A), and regulator of cullin 1 (ROC1). This complex ubiquitinates many other proteins. Through mechanisms that have not yet been fully elucidated, cerebellin ubiquitination of target proteins leads to increased levels of fibroblast growth factor 8 (FGF8) and fibroblast growth factor 10 (FGF10). FGF8, in turn, regulates many developmental processes, such as the formation of limb and auditory vesicles. The end result is that this ubiquitin ligase complex is important for limb growth in the embryo. In the absence of cerebellin, DDB1 forms a complex with DDB2 that acts as a DNA damage binding protein.
[0006] Bifunctional compounds, such as those described in U.S. Patent Application Publication Nos. 2015-0291562 and 2014-0356322 (incorporated herein by reference), are used to recruit endogenous proteins to E3 ubiquitin ligases for degradation. Specifically, this disclosure provides bifunctional or proteolytic targeting chimeric (PROTAC) compounds that are useful as targeted ubiquitination modulators of a variety of polypeptides and other proteins that, following targeted ubiquitination, are degraded and / or otherwise inhibited by the bifunctional compounds.
[0007] There is a continuing need in the art for effective treatments for diseases associated with (i) aberrant BCL6 expression and / or activity and / or (ii) overexpression or aggregation of the B-cell lymphoma 6 protein (BCL6). However, nonspecific effects and the inability to target and modulate BCL6 remain obstacles to the development of effective treatments. Therefore, small molecule therapeutics that target BCL6 and exploit or enhance the substrate specificity of E3 ubiquitin ligases (e.g., cerebellin) would be very useful. Summary of the Invention

[0037] BRIEF DESCRIPTION OF THE DRAWINGS
[0038] The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate several embodiments of the present disclosure and, together with the specification, serve to explain the principles of the present disclosure. The accompanying drawings are only for the purpose of illustrating embodiments of the present disclosure and should not be construed as limiting the present disclosure. Further objects, features, and advantages of the present disclosure will become apparent from the following detailed description taken in conjunction with the accompanying drawings, which illustrate exemplary embodiments of the present disclosure, wherein:
[0039] Figures 1A-1B . Demonstration of the general principle of the heterobifunctional degradable compound A disclosed herein. Figure 1A Exemplary heterobifunctional degradative compound A comprises a protein targeting moiety (PTM; rectangle), a ubiquitin ligase binding moiety (ULM; triangle), and optionally, a linker moiety (L; bold black line) that couples or tethers the PTM to the ULM. Figure 1BThe functional use of heterobifunctional degradative compound A as described herein is demonstrated. Briefly, the ULM recognizes and binds to a specific E3 ubiquitin ligase, and the PTM binds and recruits the target protein, bringing it into close proximity with the E3 ubiquitin ligase. Typically, the E3 ubiquitin ligase is complexed with an E2 ubiquitin conjugating protein and, alone or through an E2 protein, catalyzes the attachment of ubiquitin (small filled ellipse) to a lysine on the target protein via an isopeptide bond. The polyubiquitinated protein (far right) is then targeted for degradation by the cell's proteasome machinery.

[0050] The following is a detailed description provided to assist those skilled in the art in practicing the present disclosure. Those skilled 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, drawings, and other references mentioned herein are expressly incorporated by reference in their entirety.
[0051] 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 disclosure belongs. The terms used in this specification are only used to describe specific embodiments and are not intended to limit this disclosure.
[0052] 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 (e.g., in the case of a group containing multiple carbon atoms, in which case each number of carbon atoms falling within the range is provided), between the upper and lower limits of the range, and any other stated or intervening value within the stated range is encompassed within this disclosure. The upper and lower limits of these smaller ranges, which may independently be included in smaller ranges, are also encompassed within this disclosure, subject to any specifically excluded limitations in the stated range. Where a stated range includes one or both of the limits, ranges excluding either or both of the included limits are also encompassed within this disclosure.
[0053] The following terms are used to describe the present disclosure. Where a term is not specifically defined herein, the term is given the art-recognized meaning as applied by ordinary skill in the art in the context of its use in describing the present disclosure.
[0054] As used herein and in the appended claims, the articles "a" and "an" are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article, unless the context clearly dictates otherwise. For example, "an element" means one element or more than one element.
[0055] As used herein in the specification and claims, the phrase "and / or" should be understood to mean "either or both" of the elements so combined, i.e., the elements are present in combination in some cases and separately in other cases. Multiple elements listed with "and / or" should be interpreted in the same manner, i.e., "one or more" of the elements so combined. In addition to the elements specifically identified by the "and / or" clause, other elements may optionally be present, whether related or unrelated to those specifically identified. Thus, as a non-limiting example, when used in conjunction with open language such as "comprising," a reference to "A and / or B" may, in one embodiment, refer to only A (optionally including elements other than B); in another embodiment, refer to only B (optionally including elements other than A); in yet another embodiment, refer to both A and B (optionally including other elements); and so on.
[0056] As used herein in this specification and claims, "or" should be understood to have the same meaning as "and / or" as defined above. For example, when the items in a list are separated, "or" or "and / or" should be interpreted as inclusive, i.e., including at least one element in many elements or a list of elements, but also including more than one element and optionally other unlisted items. Only explicitly indicating the opposite term, such as "only one of..." or "exactly one of..." or when used in the claims, "consisting of..." will refer to including exactly one element in a plurality of elements or a list of elements. In general, when previously being an exclusive term such as "any one," "one of," "only one," or "exactly one," as used herein, the term "or" should only be interpreted as indicating exclusive alternatives (i.e., "one or the other but not both").
[0057] In the claims and the foregoing description, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving," "having," "consisting of," and the like are to be understood as open-ended, i.e., meaning 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 Section 2111.03 of the United States Patent Office Manual of Patent Examining Procedures.
[0058] It should also be understood that in certain methods described herein that include more than one step or action, the order of the steps or actions of the method are not necessarily limited to the order in which the steps or actions of the method are recited unless the context dictates otherwise.
[0059] The term "ubiquitin ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to specific substrate proteins to target them for degradation. For example, the cerebellum protein E3 ubiquitin ligase, alone or in combination with an E2 ubiquitin conjugating enzyme, causes ubiquitin to attach to lysines on target proteins and subsequently targets specific protein substrates for degradation by the proteasome. Therefore, E3 ubiquitin ligases, alone or in combination with an E2 ubiquitin conjugating enzyme, are responsible for transferring ubiquitin to the target protein. Generally speaking, ubiquitin ligases involve polyubiquitination, where a second ubiquitin is attached to a first ubiquitin; a third ubiquitin is attached to a second ubiquitin, and so on. Polyubiquitination marks proteins for degradation by the proteasome. However, there are some ubiquitination events that are limited to monoubiquitination, in which only a single ubiquitin is added to the substrate molecule by the ubiquitin ligase. Monoubiquitinated proteins are not targeted for degradation by the proteasome, but can be altered in their cellular location or function, for example, by binding to other proteins with domains capable of binding ubiquitin. To complicate matters further, different lysines on ubiquitin can be targeted by E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin that is recognized by the proteasome.
[0060] The term "patient" or "subject" is used throughout the specification to describe an animal, preferably a human or domesticated animal, to whom treatment, including prophylactic treatment, is provided with a composition according to the present disclosure. For treatment of those infections, conditions, or disease states that are specific to a particular animal (e.g., a human patient), the term patient refers to that particular animal, including domesticated animals such as dogs or cats or farm animals such as horses, cattle, sheep, etc. In general, in this disclosure, unless otherwise specified or implied by the context in which the term is used, the term patient refers to a human patient.
[0061] The term "effective" is used to describe an amount of a compound, composition, or component that, when used in the context of its intended use, achieves the intended result. The term effective includes all other effective amount or effective concentration terms otherwise described or used in this application.

[0418] The compounds of the present disclosure can be synthesized using standard synthetic methods and procedures for preparing organic molecules and functional group transformations and manipulations, including the use of protecting groups, such as can be obtained from the relevant scientific literature or from standard reference textbooks in the field according to the present disclosure. Although not limited to any one or more sources, recognized reference textbooks for organic synthesis include: Smith, MB; March, "March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure", 5th edition; John Wiley & Sons: New York, 2001; and Greene, TW; Wuts, PGM "Protective Groups in Organic Synthesis", 3rd edition; John Wiley & Sons: New York, 1999. The synthetic methods described in U.S. Patent Application Publication No. 2022 / 0395576 and International Publication No. 2022 / 221673 are incorporated herein by reference in their entirety.
[0419] The term "independently" is used herein to indicate that variables are independently applied, varying independently from application to application.
[0420] The term "alkyl" in this context shall mean a straight-chain, branched or cyclic fully saturated hydrocarbon or alkyl group, preferably C1-C 10 , more preferably C1-C6, alternatively C1-C3 alkyl, it can be optionally substituted.The example of alkyl is methyl, ethyl, n-butyl, sec-butyl, n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyl, isopropyl, 2-methylpropyl, cyclopropyl, cyclopropyl-methyl, cyclobutyl, cyclopentyl, cyclopentylethyl, cyclohexylethyl and cyclohexyl etc.In certain embodiments, alkyl is by halogen group (At, Br, Cl, F or I) end-blocking.In certain preferred embodiments, according to compound of the present disclosure, can be used for being covalently bound to dehalogenase.These compounds generally contain the side chain (usually connected by polyethylene glycol group) of alkyl end-blocking, and the far-end of described alkyl has halogen substituent (usually chlorine or bromine), so that the compound containing this type of part is covalently bound to protein.
[0421] The term "alkenyl" refers to a linear, branched or cyclic C2-C 10 (Preferably C2-C6) hydrocarbon group.
[0422] The term "alkenyl" refers to a linear, branched or cyclic C2-C 10 (Preferably C2-C6) hydrocarbon group.
[0423] The term "alkylene" when used refers to a -(CH2) n -group (n is typically an integer from 0 to 6). When substituted, the alkylene group is preferably substituted with a C1-C6 alkyl group (including a cyclopropyl or tert-butyl group) on one or more of the methylene groups, but may also be substituted with one or more halogen groups, preferably 1 to 3 halogen groups or one or two hydroxyl groups, O-(C1-C6 alkyl) groups, or amino acid side chains as otherwise disclosed herein. In certain embodiments, the alkylene group may be substituted with a carbamate or alkoxy group (or other group), which is further substituted with a polyethylene glycol chain (a polyethylene glycol chain of 1 to 10, preferably 1 to 6, typically 1 to 4 ethylene glycol units), which is substituted (preferably, but not exclusively, at the distal end of the polyethylene glycol chain); an alkyl chain substituted with a single halogen group (preferably a chloro group). In other embodiments, the alkylene (typically methylene) group can be substituted with an amino acid side chain group, such as a side chain group of a natural or unnatural amino acid, for example, alanine, β-alanine, arginine, asparagine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, phenylalanine, histidine, isoleucine, lysine, leucine, methionine, proline, serine, threonine, valine, tryptophan, or tyrosine.
[0424] The term "unsubstituted" shall mean substituted only with hydrogen atoms. A carbon atom range including CO means that the carbon is absent and replaced with H. Thus, a carbon atom range of CO-C6 includes 1, 2, 3, 4, 5, and 6 carbon atoms, and for CO, H replaces the carbon.
[0425] The term "substituted" or "optionally substituted" shall independently refer (i.e., when multiple substituents are present, each substituent is independent of the other substituents) to one or more substituents (independently up to five substituents, preferably up to three substituents, typically 1 or 2 substituents, on a moiety in a compound according to the present disclosure, and may include substituents which themselves may be further substituted) at any carbon (or nitrogen) position on the molecule in the context, and include substituents such as hydroxy, thiol, carboxyl, cyano (C≡N), nitro (NO2), halogen (preferably 1, 2 or 3 halogens, especially on alkyl, especially methyl such as trifluoromethyl), alkyl (preferably C1-C ... 10, more preferably C1-C6), aryl (especially phenyl and substituted phenyl, such as benzyl or benzoyl), alkoxy (preferably C1-C6 alkyl or aryl, including phenyl and substituted phenyl), thioether (C1-C6 alkyl or aryl), acyl (preferably C1-C6 acyl), ester or thioester (preferably C1-C6 alkyl or aryl) including alkylene ester (so that the attachment is on the alkylene group rather than on the ester function which is preferably substituted by C1-C6 alkyl or aryl), preferably C1-C6 alkyl or aryl, halogen (preferably F or Cl), amine (including five-membered or six-membered cyclic alkylene amine, also Including C1-C6 alkylamine or C1-C6 dialkylamine, wherein the alkyl group may be substituted with one or two hydroxy groups) or optionally substituted -N(C0-C6 alkyl)C(O)(O-C1-C6 alkyl) group (which may be optionally substituted with a polyethylene glycol chain, the polyethylene glycol chain further being bound to an alkyl group containing a single halogen, preferably chlorine, substituent), hydrazine, amine group (which is preferably substituted with one or two C1-C6 alkyl groups (including carboxamide optionally substituted with one or two C1-C6 alkyl groups)), alkanol (preferably C1-C6 alkyl or aryl), or alkanoic acid (preferably C1-C6 alkyl or aryl). Substituents according to the present disclosure may include, for example, -SiR1R2R3 groups, wherein R1 and R2 are each as described elsewhere herein, and R3 is H or C1-C6 alkyl, preferably R1, R2, R3 in this context are C1-C3 alkyl (including isopropyl or tert-butyl). Each of the above groups may be directly attached to the substituted moiety, or alternatively, the substituent may be attached via an optionally substituted -(CH2) m - or alternatively optionally substituted -(OCH2) m -、-(OCH2CH2) m -or-(CH2CH2O) m -group (which may be substituted by any one or more of the above substituents) is attached to the substituted moiety (preferably in the case of an aryl or heteroaryl moiety). As identified above, alkylene-(CH2) m -or-(CH2) n-Groups or other chains (such as ethylene glycol chains) can be substituted at any position on the chain. Preferred substituents on the alkylene group include halogen or C1-C6 (preferably C1-C3) alkyl, which can be optionally substituted with one or two hydroxyl groups, one or two ether groups (O-C1-C6 groups), up to three halogen groups (preferably F), or side chains as otherwise described herein and optionally substituted amides (preferably formamides substituted as described above) or carbamate groups (typically with one or two C0-C6 alkyl substituents, which can be further substituted). In certain embodiments, the alkylene group (typically a single methylene group) is substituted with one or two optionally substituted C1-C6 alkyl groups, preferably C1-C4 alkyl groups, most typically methyl or O-methyl, or the side chains of amino acids as described elsewhere herein. In the present disclosure, a portion in the molecule can be optionally substituted with up to five substituents, preferably up to three substituents. Most often, in the present disclosure, a substituted portion is substituted with one or two substituents.
[0426] The term "substituted" (each substituent being independent of any other substituent) in the context in which it is used shall also mean C1-C6 alkyl, C1-C6 alkoxy, halogen, amide, carboxamide, sulfones (including sulfonamides), keto, carboxyl, C1-C6 ester (oxyester or carbonyl ester), C1-C6 keto, urethane-OC(O)-NR1R2 or -N(R1)-C(O)-O-R1, nitro, cyano and amine (especially including C1-C6 alkylene-NR1R2, mono- or di-C1-C6 alkyl-substituted amines, which may be optionally substituted with one or two hydroxy groups). Unless otherwise specified, each of these groups in the context contains between 1 and 6 carbon atoms. In certain embodiments, preferred substituents will include, for example, -NH-, -NHC(O)-, -O-, =O, -(CH2) m - (wherein m and n are in this context 1, 2, 3, 4, 5 or 6), -S-, -S(O)-, SO2- or -NH-C(O)-NH-, -(CH2) n OH, -(CH2) n SH, -(CH2) n COOH, C1-C6 alkyl, -(CH2) n O-(C1-C6 alkyl), -(CH2) n C(O)-(C1-C6 alkyl), -(CH2) n OC(O)-(C1-C6 alkyl), -(CH2) n C(O)O-(C1-C6 alkyl), -(CH2) n NHC(O)-R1, -(CH2) nC(O)-NR1R2, -(OCH2) n OH, -(CH2O) n COOH, C1-C6 alkyl, -(OCH2) n O-(C1-C6 alkyl), -(CH2O) n C(O)-(C1-C6 alkyl), -(OCH2) n NHC(O)-R1, -(CH2O) n C(O)-NR1R2, -S(O)2-R S 、-S(O)-R S (R S is C1-C6 alkyl or -(CH2) m In the chemical context of the defined compounds and the substituents used, the term "substituted" shall also mean optionally substituted aryl or heteroaryl or optionally substituted heterocyclyl as otherwise described herein. The alkylene group may also be substituted as otherwise disclosed herein, preferably with an optionally substituted C1-C6 alkyl group (methyl, ethyl or hydroxymethyl or hydroxyethyl being preferred, thus providing a chiral center), a side chain of an amino acid group as otherwise described herein, an amide group as described above, or a urethane group OC(O)-NR1R2 group (wherein R1 and R2 are as otherwise described herein), although many other groups may also be used as substituents.

On days 3 and 6-7, samples were split into new 48-well plates for reprocessing, and 20% were split into 96-well plates for cell viability measurement using CellTiter-Glo (CTG). The split cells in the 48-well plates were reprocessed and cultured until day 9, at which time 20% of each sample was analyzed by CTG. The dose response is plotted as a percentage of the vehicle (DMSO) control ( Figure 3A and Figure 3B ). The graph represents at least two independent proliferation assays for each cell line. Each Compound A treatment showed significant inhibition of DLBCL cell growth, and this effect was concentration-dependent.
