[0003] This application claims the benefit of U.S. Provisional Application 62 / 334,130, filed May 10, 2016. The entire contents of that application are incorporated herein by reference for all purposes. Technical Field

[0004] This invention provides compounds having a spirocyclic E3 ubiquitin ligase targeting moiety (degradation determinant (Degron)), the targeting moiety being usable as is or linked to a targeting ligand for a protein selectively degraded in vivo. This invention also provides methods of using such compounds, compositions thereof, and methods of preparing them. Background Technology

[0005] Protein degradation is a highly regulated and essential process for maintaining cellular homeostasis. The selective identification and removal of damaged, misfolded, or excess proteins are achieved through the ubiquitin-proteasome pathway (UPP). The UPP is essentially central to regulating almost all cellular processes, including antigen processing, apoptosis, organelle biogenesis, cell cycle, DNA transcription and repair, differentiation and development, immune responses and inflammation, neural and muscular degeneration, neural network morphogenesis, regulation of cell surface receptors, ion channels and secretory pathways, responses to stress and extracellular regulators, ribosome biogenesis, and viral infection.

[0006] Multiple ubiquitin molecules are covalently linked to terminal lysine residues via E3 ubiquitin ligase to label proteins for proteasomal degradation. The protein is then digested into small peptides and ultimately into its constituent amino acids, which serve as building blocks for new proteins. Defective proteasomal degradation is associated with a variety of clinical conditions, including Alzheimer's disease, Parkinson's disease, Huntington's disease, muscular dystrophy, cardiovascular disease, and cancer.

[0007] There are more than 600 E3 ubiquitin ligases that promote the ubiquitination of different proteins in vivo, which can be divided into four families: HECT domain E3, U-box E3, monomeric RING E3, and multi-subunit E3. For general references, see Li et al. (PLOS One, 2008, 3, 1487), titled “Genome-wide and functional annotation of human E3 ubiquitin ligases identifies MULAN, a mitochondrial E3 that regulates the organelle's dynamics and signaling.”; Berndsen et al. (Nat. Struct. Mol. Biol., 2014, 21, 301-307), titled “New insights into ubiquitin E3 ligase mechanism”; Deshaies et al. (Ann. Rev. Biochem., 2009, 78, 399-434), titled “RING domain E3 ubiquitin ligases.”; and Spratt et al. (Biochem. 2014, 458, 421-437), titled “RBR E3ubiquitin ligases: new structures, new insights, new…” questions.”; and Wang et al. (Nat. Rev. Cancer., 2014, 14, 233-347), titled “Roles of F-box proteins in cancer.”

[0008] In 1995, Gosink et al. (Proc. Natl. Acad. Sci. USA 1995, 92, 9117-9121) provided an in vitro proof-of-concept for engineered peptides to selectively direct the ubiquitination of intracellular proteins in their publication "Redirecting the Specificity of Ubiquitination by Modifying Ubiquitin-Conjugating Enzymes". Nawaz et al. (Proc. Natl. Acad. Sci. USA 1999, 96, 1858-1862) described ER degradation using the ubiquitin-proteasome pathway in their publication "Proteasome-Dependent Degradation of the Human Estrogen Receptor".

[0009] Proteinex, Inc. filed a patent application in February 1999, published as U.S. Patent 6,306,663, seeking protection for a method of generating compounds for activating the ubiquitination of target proteins, comprising covalently linking a target protein binding element capable of specifically binding to the target protein via a ubiquitination recognition element. Proteinex describes the invention as usable for controlling protein levels in eukaryotes. While the '663 patent may be based on a first patent application describing a high-level concept of how to manipulate a UPP system to degrade selected proteins in vivo, the patent does not provide sufficient detail to allow a person skilled in the art to readily construct the range of proposed compounds. For example, regarding ubiquitination recognition elements, a person skilled in the art is specifically advised to use standard methods for drug discovery and screening for suitable small molecules that will bind to the binding enzyme. Proteinex also emphasizes the use of peptides as ubiquitination recognition elements, which could pose significant difficulties for oral drug administration.

[0010] Since then, therapeutic interventions utilizing the ubiquitination-proteasome pathway have attracted considerable interest from the scientific community. Zhou et al. from Harvard Medical School (Mol. Cell 2000, 6, 751-756) described an engineered receptor capable of directing ubiquitination in mammalian and yeast cells in a publication titled "Harnessing the Ubiquitination Machinery to Target the Degradation of Specific Cellular Proteins".

[0011] Following these early publications and others in the mid-to-late 1990s, Craig Crews and colleagues (Yale University) also recognized that molecules capable of binding target proteins and ubiquitin ligases could lead to the degradation of target proteins. Their first description of such a compound is provided in U.S. Patent 7,041,298, filed in September 2000 and granted in May 2006 by Deshaies et al., entitled “Proteolysis Targeting Chimeric Pharmaceutical,” which describes “PROTAC” consisting of a small molecule binder of MAP-AP-2 linked to a peptide capable of binding the F-box protein β-TRCP. Information from Patent '298 is also presented in the corresponding publication by Sakamoto et al. (Proc. Natl. Acad. Sci. USA 2001, 98, 8554-8559) entitled “Protacs: Chimeric Molecules That Target Proteins to the Skp1–Cullin–F Box Complex for Ubiquitination and Degradation.” The publication by Sakamoto et al. (Mol.Cell.Proteomics 2003,2,1350-1358) entitled "Development of Protacs to Target Cancer - Promoting Proteins for Ubiquitination and Degradation" describes a similar PROTAC (PROTAC2) that degrades estrogen and androgen receptors without degrading MAP-AP-2.

[0012] The first E3 ligase successfully targeted with a small molecule was MDM2, which ubiquitinates the tumor suppressor p53. The targeting ligand was the HDM2 / MDM2 inhibitor identified by Vassilev et al. (Science 2004, 303, 844-848) in their paper titled "In Vivo Activation of the P53 Pathway by Small-Molecule Antagonists of MDM2".

[0013] In 2004, Schneekloth et al. (J. Am. Chem. Soc. 2004, 126, 3748-3754), entitled "Chemical Genetic Control of Protein Levels: Selective in Vivo Targeted Degradation") described other examples of direct small molecule-induced recruitment of target proteins to the proteasome for degradation upon addition to cultured cells. Schneekloth et al. described a degrader (PROTAC3) targeting the FK506-binding protein (FKBP12) and showed that both PROTAC2 and PROTAC3 hit their respective targets using green fluorescent protein (GFP) imaging. The state of the field at that time was described in Schneekloth et al.'s publication (ChemBioChem 2005, 6, 40-46) entitled "Chemical Approaches to Controlling Intracellular Protein Degradation".

[0014] The publication by Schneekloth et al. (Bioorg.Med.Chem.Lett.2008,18,5904-5908) entitled "Targeted Intracellular Protein Degradation Induced by a Small Molecule:EnRoute to Chemical Proteomics" describes a degrading agent consisting of two small molecules linked by PEG, which degrades the androgen receptor in vivo by simultaneously binding to the androgen receptor and ubiquitin E3 ligase.

[0015] WO 2013 / 170147, submitted by Crews et al., entitled "Compounds Useful for Promoting Protein Degradation and Methods of Using Same," describes compounds containing a protein-degrading moiety covalently bound to a linker, wherein the compound's ClogP is equal to or greater than 1.5. Specifically, this specification discloses protein-degrading compounds that incorporate certain small molecules that can bind to E3 ubiquitin ligases.

[0016] In unrelated parallel studies, scientists are investigating the toxicity of thalidomide. Ito et al. (Science 2010, 327, 1345-1350), titled "Identification of a Primary Target of Thalidomide Teratogenicity," describe cereblon as a thalidomide-binding protein. Cereblon forms part of an E3 ubiquitin ligase protein complex that interacts with impaired DNA-binding protein 1, forming an E3 ubiquitin ligase complex with Cullin 4 and E2-binding protein ROC1 (also known as RBX1), where it acts as a substrate acceptor to select proteins for ubiquitination. This study suggests that in vivo thalidomide-cereblon binding may be the cause of thalidomide teratogenicity. Despite the discovery of teratogenicity of thalidomide in the mid-1960s, the compound and related structures were still found to be useful as anti-inflammatory, anti-angiogenic, and anticancer agents (see Bartlett et al. (Nat. Rev. Cancer 2004, 4, 314-322), titled "The Evolution of Thalidomide and Its Imid Derivatives as Anticancer Agents").

[0017] Public knowledge about the binding of thalidomide to cereblon E3 ubiquitin ligase led to research investigations that incorporated thalidomide and certain derivatives into compounds to target and destroy proteins. Two groundbreaking papers were published in Science in 2014: G. Lu et al., The Myeloma Drug Lenalidomide Promotes the Cereblon-Dependent Destruction of Ikaros Proteins, Science, 343, 305-309 (2014); and J. Kronke et al., Lenalidomide Causes Selective Degradation of IKZF1 and IKZF3 in Multiple Myeloma Cells, Science, 343, 301-305 (2014).

[0022] While progress has been made in the regulation of UPP for protein degradation in vivo, it would be useful to have other compounds and methods to more fully utilize UPP for therapeutic purposes.

[0023] One object of the present invention is to provide novel compounds, methods, compositions, and manufacturing methods that can be used to degrade selected proteins in vivo. Summary of the Invention

[0024] Compounds and methods for treating patients with conditions treatable via protein degradation through the ubiquitin-proteasome pathway (UPP) are proposed. The invention comprises administering an effective amount, optionally in a pharmaceutically acceptable carrier, of one or a combination of a spirocyclic "degrominer" of Formula I or II, or a spirocyclic "degrominer" of Formula III or IV, as further described herein, to a patient (typically human) in need.

[0061] Formulas I and II are novel bifunctional compounds having a spirocyclic E3 ubiquitin ligase targeting moiety (degradation determinant) linked to a targeting ligand (described in more detail below), which recruits selected target proteins to the E3 ubiquitin ligase for degradation.

[0062] In Formulas I and II, the spirocyclic moiety is covalently linked to the target protein ligand via a linker, which can have different lengths and functions, as described in detail herein. In one embodiment, the spirocyclic degradation determinant moiety is directly linked to the target ligand (i.e., the linker is a bond).

In one embodiment, each branch has 10, 8, 6, 4, 3, 2 carbons, or one carbon.

[0063] In one embodiment, a pharmaceutical formulation is provided comprising a therapeutically effective amount of a spirocyclic degradation determinant of Formula I or Formula II or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.

[0064] In another aspect of the invention, a spirocyclic degradation determinant of formula III or IV is provided, which binds to cereblon in vivo and is therefore available for use in treating conditions that can be improved by inhibiting the E3 ligase of cereblon as its protein subunit. The spirocyclic degradation determinant of formula III or IV, or a pharmaceutically acceptable salt thereof, can be administered in effective amounts for those indications known against the cereblon binders thalidomide, pomalidomide, or lenalidomide.

[0075] Spirocyclic compounds of formulas III and IV do not include linkers or targeting ligands. When administered in effective amounts to a host (including humans), these compounds of formulas III and IV can be used as therapeutic agents to treat medical conditions, including but not limited to those that can be treated with thalidomide, pomalidomide, or lenalidomide.

[0367] Figure 9 This is a dendrogram of the human bromine domain family of proteins organized into eight subfamilies, which relates to epigenetic signaling and chromatin biology. (Optional) Figure 9 Any protein of the bromine domain family may be used as a target protein according to the present invention. Detailed Implementation

[0368] I. Definition

[0369] Compounds are described using standard nomenclature. 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 pertains.

[0370] The compounds in any of the formulas described herein may be in the form of racemic mixtures, enantiomers, mixtures of enantiomers, diastereomers, mixtures of diastereomers, tautomers, N-oxides, or isomers; for example, rotational isomers, as each is explicitly described unless explicitly excluded by the context.

[0371] The terms “a” and “an” do not indicate a limitation of quantity, but rather the presence of at least one of the mentioned items. The term “or” means “and / or”. Unless otherwise stated herein, the description of the range of values ​​is intended only as a shorthand method for individually referring to each individual value falling within the range, and each individual value is incorporated into the specification as if it were described individually herein. The endpoints of all ranges are included within the range and can be combined independently. Unless otherwise stated herein or where the context clearly contradicts, all methods described herein may be performed in a suitable order. Unless otherwise stated, the use of examples or exemplary language (e.g., “such”) is intended only to better illustrate the invention and not to limit the scope of the invention.

[0372] This invention comprises compounds of formulas I, II, III, and IV having at least one desired atomic isotope substitution in amounts higher than the natural abundance of that isotope, i.e., enriched. An isotope is an atom having the same atomic number but different mass numbers, i.e., atoms with the same number of protons but different numbers of neutrons. Examples of isotopes that can be introduced into the compounds of this invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine, respectively, as follows: 2H, 3 H, 11 C 13 C 14 C 15 N、 18 F, 31 P, 32 P, 35 S, 36 Cl and 125 I. In one non-limiting embodiment, the isotope-labeled compound can be used for metabolic studies (using, for example...) 14 C) Reaction kinetics studies (using, for example) 2 H or 3 H) Detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT), including drug or substrate tissue distribution determination, or used in patient radiotherapy. Specifically, 18 F-labeled compounds may be particularly desirable for PET or SPECT studies. Isotopically labeled compounds of the present invention and their prodrugs can generally be prepared by replacing non-isotopically labeled reagents with readily available isotopically labeled reagents, through the procedures disclosed in the scheme or examples and the preparation described below.

[0373] Isotopic substitution, such as deuterium substitution, can be partial or complete. Partial deuterium substitution means that at least one hydrogen atom is substituted with deuterium. In some embodiments, the isotope is enriched by 90, 95, or 99% or more at any site of interest. In a non-limiting embodiment, deuterium is enriched by 90, 95, or 99% at the desired site.

[0374] In one non-limiting embodiment, the substituted hydrogen atom may be provided as a deuterium atom in any compound of Formula I, II, III, or IV. In one non-limiting embodiment, the substitution of the hydrogen atom as a deuterium atom occurs independently within one or more groups selected from any of the R and variables, linkers, and targeting ligands described herein. For example, when any group is or contains (e.g., by substitution) a methyl, ethyl, or methoxy group, the alkyl residue may be deuterated (in a non-limiting embodiment, CDH2, CD2H, CD3, CH2CD3, CD2CD3, CHDCH2D, CH2CD3, CHDCHD2, OCDH2, OCD2H, or OCD3, etc.). In some other embodiments, when two substituents combine to form a ring, the unsubstituted carbon may be deuterated.

[0375] The compounds of the present invention can form solvates with solvents, including water. Therefore, in one non-limiting embodiment, the present invention includes the solvated form of the compounds. The term "solvate" refers to a molecular complex of a compound of the present invention (including its salts) with one or more solvent molecules. Non-limiting examples of solvents are water, ethanol, isopropanol, dimethyl sulfoxide, acetone, and other common organic solvents. The term "hydrate" refers to a molecular complex comprising a compound of the present invention and water. Pharmaceutically acceptable solvates according to the present invention include those in which the solvent may be isotopically substituted (e.g., D2O, d6-acetone, d6-DMSO). Solvates may be in liquid or solid form.

[0376] A hyphen ("-") not between two letters or symbols is used to indicate the connection point of a substituent. For example, -(C=O)NH2 is a carbon atom linked through a carbonyl (C=O) group.

[0377] "Alkyl" is a branched or straight-chain saturated aliphatic hydrocarbon group. In one non-limiting embodiment, the alkyl group contains 1 to about 12 carbon atoms, more typically 1 to about 6 carbon atoms or 1 to about 4 carbon atoms. In one non-limiting embodiment, the alkyl group contains 1 to about 8 carbon atoms. In some embodiments, the alkyl group is C1-C2, C1-C3, C1-C4, C1-C5, or C1-C6. The specified ranges as used herein refer to alkyl groups having each member of the range described as independent species. For example, the term C1-C6 alkyl as used herein refers to straight-chain or branched alkyl groups having 1, 2, 3, 4, 5, or 6 carbon atoms, and is intended to mean that each of these is described as an independent species, and thus each subset is considered to be disclosed separately. For example, the term C1-C4 alkyl as used herein refers to straight-chain or branched alkyl groups having 1, 2, 3, or 4 carbon atoms, and is intended to mean that each of these is described as an independent species. Examples of alkyl groups include, but are not limited to, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, isopentyl, tert-pentyl, neopentyl, n-hexyl, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, and 2,3-dimethylbutane. In an alternative embodiment, the alkyl group may optionally be substituted. The term "alkyl" also includes cycloalkyl or carbocyclic groups. For example, when the term includes "alkane," "cycloalkyl" or "carbocyclic" may be considered as part of the definition unless explicitly excluded by the context. For example, but not limited to, the terms alkyl, alkoxy, haloalkyl, etc., may be considered to include cyclic forms of alkyl groups unless explicitly excluded by the context.

[0378] "Alkenyl" is a straight-chain or branched aliphatic hydrocarbon group having one or more carbon-carbon double bonds, which may be present along the chain's stability point. The specified range used herein refers to alkenyl groups having each member of the range described as a separate class, as described above with respect to the alkyl portion. Examples of alkenyl groups include, but are not limited to, vinyl, propenyl, allyl, propenyl, butenyl, and 4-methylbutenyl.

Typically, propylene glycol increases hydrophobicity, while propylene glycol increases hydrophilicity. The lactic acid segment tends to have a longer half-life than the glycolic acid segment. Block and random lactic-co-glycolic acid moieties, as well as ethylene glycol and propylene glycol, are known in the art to be pharmaceutically acceptable and can be modified or arranged to achieve the desired half-life and hydrophilicity. In some aspects, these units may be side-attached or dispersed with other moieties, such as aliphatic groups (including alkyl groups), heteroaliphatic groups, aryl groups, heteroaryl groups, heterocyclic groups, cycloalkyl groups, etc., as needed, to achieve suitable pharmaceutical properties.

[0545] In some embodiments, the linker can be a straight chain of 4-24 carbon atoms, wherein one or more carbon atoms in the straight chain can be replaced or substituted by oxygen, nitrogen, amide, fluorinated carbon, etc., for example as follows:

[0546]

[0547]

[0548] In some implementations, the linker may be a nonlinear chain and may be or include an aliphatic, aromatic, or heteroaromatic cyclic portion.

[0549] In some embodiments, the linker may include continuous, partially continuous or discontinuous ethylene glycol unit groups, ranging in size from about 1 to about 12 ethylene glycol units, between 1 and about 10 ethylene glycol units, from about 2 to about 6 ethylene glycol units, between about 2 and 5 ethylene glycol units, between about 2 and 4 ethylene glycol units, for example, 1, 2, 3, 4, 6, 6, 7, 8, 9, 10, 11 or 12 ethylene glycol units.

[0550] In some embodiments, the linker may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 fluorine substituents. In another embodiment, the linker is perfluorinated. In yet another embodiment, the linker is a partially or fully fluorinated polyether. Non-limiting examples of fluorinated linkers include:

[0551]

[0552] In some implementations, when the targeting ligand binds to more than one protein (i.e., not entirely selective), selectivity can be enhanced by varying the linker length, where the ligand binds to some of its targets in different binding pockets, for example, deeper or shallower than others. Therefore, the length can be adjusted as needed.

[0553] target protein

[0554] Cellular homeostasis and normal cellular functions such as proliferation, differentiation, and cell death require the degradation of cellular proteins. When this system becomes dysfunctional or fails to recognize and reduce abnormal protein behavior in the body, disease states may arise in a host such as a human. As is known to those skilled in the art, as published in the literature and patent applications, and as presented in scientific reports, a wide range of proteins can cause, regulate, or amplify disease in the body.

[0555] Therefore, in one embodiment, the selected degradation determinant compound of the present invention can be administered in vivo to a host in need of it in an effective amount to degrade the selected protein mediating the disease to be treated. The selected protein target can modulate the disease in humans through mechanisms of action such as modification of biological pathways, pathogen signaling or regulation of signaling cascades or cell entry. In one embodiment, the target protein is a classically unmedicatable protein because it does not have a binding pocket or active site that can be inhibited or otherwise bound, and it cannot be readily allosterically controlled. In another embodiment, the target protein is a classically medicinal protein, but for therapeutic purposes, degradation of the protein is preferred over inhibition.

[0556] The target protein is recruited using a targeting ligand. Typically, the targeting ligand binds to the target protein nonvalently. In an alternative implementation, the target protein covalently binds to a degradation determinant in a manner that may be irreversible or reversible.

[0557] In one embodiment, the selected target protein is expressed by a gene that has undergone an amplification, translocation, deletion, or inversion event that causes or is caused by a medical condition. In some aspects, the selected target protein has been post-translational modified by one or a combination of phosphorylation, acetylation, acylation (including propionylation and crotonylation), N-linked glycosylation, amidation, hydroxylation, methylation and polymethylation, O-linked glycosylation, pyroglutamylation, myristylation, farnesylation, geranylgeranylation, ubiquitination, ubiquitin-like glycosylation, or sulfation that causes or is caused by a medical condition.

[0558] As contemplated herein, the present invention includes a degradation determinant having a targeting ligand that binds to a target protein of interest. The target protein is any amino acid sequence that can bind to the degradation determinant, thereby causing a beneficial therapeutic effect in vivo through degradation. In one embodiment, the target protein is a non-endogenous peptide, such as a peptide derived from a pathogen or toxin. In another embodiment, the target protein can be an endogenous protein that mediates a disease. Endogenous proteins can be in their normal or abnormal form. For example, the target protein can be a mutant protein found in cancer cells, or a protein in which partial or complete gain or loss of function is encoded by nucleotide polymorphisms. In some embodiments, the degradation determinant targets the abnormal form of the protein rather than its normal form. In another embodiment, the target protein can mediate inflammatory or immune conditions, including autoimmune diseases. In one embodiment, the target protein is a non-endogenous protein derived from a virus; as non-limiting examples, HIV, HBV, HCV, RSV, HPV, CMV, flaviviruses, plague viruses, coronaviruses, noroviridae, etc. In one embodiment, the target protein is a non-endogenous protein derived from bacteria, such as Gram-positive bacteria, Gram-negative bacteria, or other bacteria, and may be a drug-resistant form of bacteria. In one embodiment, the target protein is a non-endogenous protein derived from fungi. In one embodiment, the target protein is a non-endogenous protein derived from a prion. In one embodiment, the target protein is a protein derived from a eukaryotic pathogen, such as a protist, helminth, etc.

[0559] In one aspect, target proteins mediate chromatin structure and function. Target proteins can mediate epigenetic processes such as DNA methylation or covalent modification of histones. One example is histone deacetylases (HDAC 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11). Alternatively, target proteins can be bromodomains, which are lysine acetylation readers (e.g., BRD1, 2, 3, 4, 5, 6, 7, 8, 9, and T). Figure 9Bromine domain family proteins were elucidated, which, for example, can serve as target proteins according to the present invention.

[0560] Other non-limiting examples of target proteins are structural proteins, receptors, enzymes, cell surface proteins, proteins involved in apoptosis signaling, aromatases, helicases, mediators of metabolic processes (anabolism or catabolism), antioxidants, proteases, kinases, oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, enzyme regulators, signal transducers, structural molecules, binding activities (proteins, lipids, carbohydrates), cell movement proteins, membrane fusion proteins, cell communication mediators, regulators of biological processes, behavioral proteins, cell adhesion proteins, proteins involved in cell death, and proteins involved in transport (including protein transporter activity, nuclear transport, ion transporters, channel transporters, carrier activity, permeases, secretases or secretory mediators, electron transporters, chaperone regulators, nucleic acid binding, transcription regulators, extracellular tissue and biogenesis regulators, and translation regulators).

[0561] In one embodiment, the target protein is a regulator of a signaling cascade associated with a known disease state. In another embodiment, the target protein mediates the condition through a mechanism different from regulating the signaling cascade. As further described herein, any protein in a eukaryotic or microbial system (including viruses, bacteria, or fungi) is a target for proteasome degradation using the present invention. The target protein may be a eukaryotic protein, and in some embodiments, it is a human protein.

[0562] In one embodiment, the target proteins are RXR, DHFR, Hsp90, kinase, HDM2, MDM2, bromine-containing domain BET protein, HDAC, IDH1, Mcl-1, human lysine methyltransferase, nuclear hormone receptor, aryl hydrocarbon receptor (AHR), RAS, RAF, FLT, SMARC, KSR, NF2L, CTNB, CBLB, and BCL.

[0563] In one embodiment, the bromine-containing domain protein has histone acetyltransferase activity.

[0564] In one embodiment, the bromine-containing domain protein is BRD2, BRD3, BRD4, BRDT, or ASH1L.

[0565] In one implementation, the bromine-containing domain protein is a non-BET protein.

[0566] In one implementation, the non-BET protein is BRD7 or BRD9.

[0567] In one implementation, FLT is not FLT3. In one implementation, RAS is not RASK. In one implementation, RAF is not RAF1. In one implementation, SMARC is not SMARC2.

[0569] In another embodiment, the target protein is not selected from: EGFR, FLT3, RAF1, SMRCA2, KSR1, NF2L2, CTNB1, CBLB, BCL6, and RASK.

[0570] In one implementation, the targeting ligand is an EGFR ligand, an FLT3 ligand, a RAF1 ligand, an SMRCA2 ligand, a KSR1 ligand, an NF2L2 ligand, a CTNB1 ligand, a CBLB ligand, a BCL6 ligand, or a RASK ligand.

[0571] In one implementation, the targeting ligand is not an EGFR ligand, FLT3 ligand, RAF1 ligand, SMRCA2 ligand, KSR1 ligand, NF2L2 ligand, CTNB1 ligand, CBLB ligand, BCL6 ligand, or RASK ligand.

[0572] This invention can be used to treat a variety of disease states and / or conditions, including those in which protein dysregulation and any disease state and / or condition in which the patient would benefit from protein degradation.

[0725] III. Treatment Methods

[0726] Spirocyclic compounds of formulas I, II, III, and IV can be used in effective amounts to treat any host (including humans) suffering from any of the conditions described herein, wherein the compounds are optionally in a pharmaceutically acceptable carrier. In some embodiments, the method comprises administering an effective amount of an active compound as described herein or a salt thereof, which optionally includes a pharmaceutically acceptable excipient, carrier, adjuvant, i.e., a pharmaceutically acceptable composition, which is optionally combined with or alternates with another bioactive agent or pharmaceutical combination.

[0727] The spirocyclic degradation determinants of Formula I and Formula II as described herein, or their pharmaceutically acceptable salts, can be used to degrade target proteins that are mediators of a patient's (e.g., a human) condition. The reduction in protein levels granted by the degradation determinants of Formula I or Formula II of the present invention provides treatment for the disease state or condition in question, which is regulated by the target protein through a reduction in the level of that protein in cells (e.g., the patient's cells). When used in conjunction with compounds of Formula I or Formula II, the term "disease state or condition" is intended to refer to any disease state or condition in which a protein dysregulation involving the selected target protein occurs, and in which the degradation of such a protein in a patient can provide beneficial treatment or symptom relief for the patient in need. In some cases, the disease state or condition can be cured.

[0728] When administered to a host (including humans) in an effective amount, compounds of Formulas I and II can be used as therapeutic agents to treat tumors, cancers (solid, non-solid, diffuse, hematologic, etc.), abnormal cell proliferation, immune disorders, inflammatory disorders, hematologic disorders, myeloproliferative or lymphoproliferative disorders such as B-cell or T-cell lymphoma, multiple myeloma, breast cancer, prostate cancer, AML, ALL, ACL, lung cancer, pancreatic cancer, colon cancer, skin cancer, melanoma, Woldanström macroglobulinemia, Wescott-Aldrich syndrome, or post-transplant lymphoproliferative disorders; autoimmune diseases such as lupus, Crohn's disease, Addison's disease, and celiac disease. Diseases including: dermatomyositis, Graves' disease, thyroiditis, multiple sclerosis, pernicious anemia, reactive arthritis, lupus, or type 1 diabetes; cardiac dysfunction, including hypercholesterolemia; infectious diseases, including viral and / or bacterial infections; inflammatory conditions, including asthma, chronic peptic ulcers, tuberculosis, rheumatoid arthritis, periodontitis, ulcerative colitis, or hepatitis.

[0729] For example, when used in conjunction with a spirocyclic degradation determinant of formula III or IV, the term "disease state or condition" refers to any therapeutic indication that can be treated by reducing the activity of cereblon or a cereblon-containing E3 ligase, including but not limited to the known uses of cereblon binders thalidomide, pomalidomide, or lenalidomide. Non-limiting examples of the use of cereblon binders include multiple myeloma, hematologic disorders such as myelodysplastic syndromes, cancer, tumors, abnormal cell proliferation, breast cancer, prostate cancer, AML, ALL, ACL, lung cancer, pancreatic cancer, colon cancer, skin cancer, melanoma, HIV / AIDS, HBV, HCV, hepatitis, Crohn's disease, sarcoidosis, graft-versus-host disease, rheumatoid arthritis, Behçet's disease, tuberculosis, and myelofibrosis. Other indications include myeloproliferative or lymphoproliferative disorders such as B-cell or T-cell lymphoma, Woldanstrom macroglobulinemia, Wiscot-Aldridge syndrome, or post-transplant lymphoproliferative disorders; immune disorders, including autoimmune disorders such as lupus, Addison's disease, celiac disease, dermatomyositis, Graves' disease, thyroiditis, multiple sclerosis, pernicious anemia, arthritis (especially rheumatoid arthritis), or type I diabetes; cardiac dysfunction, including hypercholesterolemia; infectious diseases, including viral and / or bacterial infections, as generally described herein; and inflammatory conditions, including asthma, chronic peptic ulcers, tuberculosis, rheumatoid arthritis, periodontitis, and ulcerative colitis.

[0730] In some embodiments, the present invention provides the administration of an effective amount of a compound of formula I, II, III or IV to treat a patient (e.g., a human) suffering from an infectious disease, wherein the treatment targets a target protein of an infectious agent (formulas I and II), or works by binding to cereblon or its E3 ligase (formulas III and IV) (optionally in combination with another bioactive agent). Disease states or conditions can be caused by the following: microbial agents or other exogenous agents such as viruses (as non-limiting examples, HIV, HBV, HCV, HSV, HPV, RSV, CMV, Ebola virus, flavivirus, rotavirus, influenza, coronavirus, EBV, viral pneumonia, drug-resistant viruses, avian influenza, RNA viruses, DNA viruses, adenovirus, poxvirus, microRNA virus, capsular virus, orthomyxovirus, retrovirus, or hepatotropic DNA virus), bacteria (including but not limited to Gram-negative bacteria, Gram-positive bacteria, atypical bacteria, Staphylococcus, Streptococcus, Escherichia coli, Salmonella, Helicobacter pylori, meningitis, gonorrhea, Chlamydia, Mycoplasma, etc.), fungi, protozoa, intestinal worms, worms, prions, parasites, or other microorganisms.

[0731] In some embodiments, the symptoms treated with the compounds of the present invention are those related to abnormal cell proliferation. Abnormal cell proliferation, particularly excessive proliferation, can be caused by a variety of factors, including gene mutations, infections, exposure to toxins, autoimmune diseases, and benign or malignant tumors.

[0732] Many skin conditions are associated with excessive cell proliferation. For example, psoriasis is a benign skin disease typically characterized by plaques covered with thickened scales. This disease is caused by an increase in the proliferation of epidermal cells for unknown reasons. Chronic eczema is also associated with significant excessive proliferation of the epidermis. Other diseases caused by excessive proliferation of skin cells include atopic dermatitis, lichen planus, warts, pemphigus vulgaris, actinic keratosis, basal cell carcinoma, and squamous cell carcinoma.

[0733] Other proliferative cell disorders include angiogenesis disorders, fibrosis disorders, autoimmune disorders, graft-versus-host rejection, tumors, and cancer.

[0734] Angiogenic disorders include both angiogenesis and vascularization. The proliferation of smooth muscle cells during plaque development in vascular tissue leads to conditions such as restenosis, retinopathy, and atherosclerosis. Both cell migration and cell proliferation play a role in the formation of atherosclerotic lesions.

[0735] Fibrotic disorders are typically caused by abnormal formation of the extracellular matrix. Examples of fibrotic disorders include cirrhosis of the liver and mesangial proliferative cell disease of the glomeruli. Cirrhosis is characterized by an increase in extracellular matrix components, leading to liver scarring. Cirrhosis can cause diseases such as liver cirrhosis. The increase in extracellular matrix leading to liver scarring can also be caused by viral infections such as hepatitis. Adipocytes appear to play a major role in cirrhosis.

[0736] Glomerular mesangial disorders are caused by the abnormal proliferation of glomerular mesangial cells. Glomerular mesangial hyperproliferative cell disorders include various human kidney diseases such as glomerulonephritis, diabetic nephropathy, malignant nephrosclerosis, thrombotic microangiopathy syndrome, transplant rejection, and glomerular diseases.

[0737] Another disease with a proliferative component is rheumatoid arthritis. Rheumatoid arthritis is generally considered an autoimmune disease, thought to be related to the activity of autoreactive T cells and caused by autoantibodies produced against collagen and IgE.

[0738] Other diseases that may include abnormal cell proliferation components include Bechtel syndrome, acute respiratory distress syndrome (ARDS), ischemic heart disease, postdialysis syndrome, leukemia, acquired immunodeficiency syndrome, vasculitis, lipohistiocytosis, septic shock, and general inflammation.

[0739] Skin contact hypersensitivity and asthma are just two examples of immune responses that can be associated with significant morbidity. Other examples include atopic dermatitis, eczema, Sjögren's syndrome (including keratoconjunctivitis sicca secondary to Sjögren's syndrome), alopecia areata, allergic reactions due to arthropod bites, Crohn's disease, aphthous ulcers, iritis, conjunctivitis, keratoconjunctivitis, ulcerative colitis, cutaneous lupus erythematosus, scleroderma, vaginitis, proctitis, and drug eruptions. These conditions may cause any one or more of the following symptoms or signs: itching, swelling, redness, blisters, crusting, ulceration, pain, desquamation, cracking, hair loss, scarring, or fluid exudation involving the skin, eyes, or mucous membranes.

[0740] In atopic dermatitis and eczema in general, immune-mediated leukocyte infiltration (particularly monocytes, lymphocytes, neutrophils, and eosinophils) into the skin plays a crucial role in the pathogenesis of these diseases. Chronic eczema is also associated with significant epidermal hyperplasia. Immune-mediated leukocyte infiltration also occurs in sites outside the skin, such as the airways of asthma and the tear-producing ocular glands of dry keratoconjunctivitis.

[0741] In one non-limiting embodiment, the compounds of the present invention are used as topical agents to treat the following conditions: contact dermatitis, atopic dermatitis, eczematous dermatitis, psoriasis, Sjögren's syndrome (including keratoconjunctivitis sicca secondary to Sjögren's syndrome), alopecia areata, allergic reactions due to arthropod bites, Crohn's disease, aphthous ulcers, iritis, conjunctivitis, keratoconjunctivitis, ulcerative colitis, asthma, allergic asthma, cutaneous lupus erythematosus, scleroderma, vaginitis, proctitis, and drug eruptions. This novel approach can also be used to reduce the infiltration of malignant leukocytes into the skin in diseases such as mycosis fungoides. By applying the compounds topically to the eyes, these compounds can also be used to treat aqueous defective dry eye conditions (e.g., immune-mediated keratoconjunctivitis) in patients suffering from these conditions.

[0742] The disease states treatable according to the present invention include, for example, asthma, autoimmune diseases such as multiple sclerosis, various cancers, ciliary diseases, cleft palate, diabetes, heart disease, hypertension, inflammatory bowel disease, intellectual disability, mood disorders, obesity, refractive errors, infertility, Angelman syndrome, Canavan disease, celiac disease, Shayma-Tuscan disease, cystic fibrosis, Duchenne muscular dystrophy, hemochromatosis, hemophilia, Cranfield syndrome, neurofibromatosis, phenylketonuria, polycystic kidney disease 1 (PKD1) or 2 (PKD2), Parsons-Weil syndrome, sickle cell disease, Ty Sachs disease, and Turner syndrome.
