[Technical Field]
[0001] Cross-reference of related applications This application claims priority from U.S. Provisional Patent Application No. 63 / 086,728, filed on 2 October 2020, which is incorporated herein by reference for all purposes.
[0002] Novel imidazopiperazine compounds and compositions, as well as their uses as pharmaceuticals for treating diseases, are disclosed herein. Methods for inhibiting the activity of transcription-activating proteins such as CBP and P300 in human or animal subjects for treating diseases such as cancer are also provided. [Background technology]
[0003] Chromatin is the combination of DNA and proteins found in the nucleus of eukaryotes, and it constitutes chromosomes. Chromatin can be classified into either heterochromatin (condensed) or euchromatin (elongated). The main protein components of chromatin are called histones, which act as a scaffold for packaging and compressing DNA into a smaller volume to fit into the nucleus. Histones are involved in the processes of mitosis and meiosis and are thought to play a crucial role in DNA expression and replication. Importantly, histones undergo post-translational modifications ("PTMs") at various amino acid sites, which regulate chromatin structure and affect transcription. These modifications provide a mechanism for "epigenetics," that is, the regulation of gene activity and expression that does not arise from direct changes in the DNA sequence.
[0004] Lysine residue acetylation is a post-translational modification (PTM) widely involved in cell signaling and disease biology. Lysine acetylation, particularly abundant in nuclear macromolecular complexes, plays a key role in chromatin regulation and transcriptional control. In cells, the primary "leaders" of the acetyl-lysine mark are bromodomains (BRDs), a diverse family of evolutionarily conserved protein-protein interaction modules that specifically recognize and bind to acetylated lysine residues. Bromodomains, along with enzymes that "write" (histone acetyltransferases, HATs) and "erase" (histone deacetylases, HDACs) acetylated lysine residues on histone and non-histone proteins, tightly regulate gene expression, thereby controlling cellular phenotypes, including proliferation, cell differentiation, and metabolism. Beyond chromatin, many other proteins, such as p53, undergo post-translational modifications and may also be recognized by bromodomain proteins. Because chromatin-mediated processes are often disregulated in cancer, targeting epigenetic leader proteins such as BET (a dual BRD4 containing a protein), CREBBP, ATAD2A, SMARCA2 / 4, and 3-element motif-containing 24 (TRIM24) makes them promising drug targets. As exemplified by the development of selective inhibitors of the bromodomain BET family, conserved BRD folds represent a promising pocket for the development of small, pharmaceutically active molecules.
[0005] Histone acetyltransferase paralogs, cyclic adenosine monophosphate response element binding proteins, binding proteins (CBP, CREBBP, or CREB binding proteins), and 300kDa adenovirus E1A binding proteins (P300 or EP300) are highly homologous and are two closely related multi-domain transcriptional activators containing both histone acetyltransferase (HAT) and bromodomains, playing crucial roles in histone acetylation. These are essential transcriptional coactivators indispensable to numerous cellular processes and are involved in several human pathological conditions, including cancer.
[0006] CBP and P300 bind to chromatin via their bromodomains, and once associated with chromatin, this complex mobilizes further transcriptional machinery to regulate gene expression, triggering the recruitment of various transcription proteins. In addition to chromatin, CBP / P300 has been shown to bind to non-histone proteins; for example, CBP has been described as recognizing acetylated p53 at K382 after DNA damage. Several studies have linked CBP / P300 to the development, maintenance, and / or progression of cancer and tumor immunity, and therefore CBP / P300 inhibitors are a target of current efforts to develop anticancer drugs. In particular, CBP has been found to regulate the expression of MYC, a transcription factor and oncogene that is widely upregulated in many human cancers, suggesting a potential therapeutic strategy for targeting multiple myeloma and other lymphoid malignancies, as well as solid tumors.
[0007] In addition, CBP and P300 are known co-activators of the androgen receptor (AR) and are involved in enhancing the response to androgens. Consistently, CBP / P300 has been proposed to play an oncogenic role in prostate cancer, and upregulation of both proteins has been observed in tumors. CBP inhibitors selectively inhibit growth in several hematological malignancies and lineage-specific tumor types, including androgen receptor-positive prostate cancer. CBP inhibitors inhibit the androgen receptor transcription program in both androgen-sensitive and castration-resistant prostate cancer, thereby inhibiting tumor growth in prostate cancer xenograft models.
[0008] CBP is also relevant to cancer immunotherapy, and the ability of CBP bromodomain inhibitors to impair Treg differentiation and suppression has been described. This activity may constitute a novel small molecule approach to enhance the response to cancer immunotherapy. [Overview of the project] [Means for solving the problem]

Examples include trimethylilyl, tert-butyldimethylsilyl, and triphenylsilyl.
[0128] Any definition herein may be used in combination with any other definition to describe a complex structural group. By convention, the suffix of any such definition is the element bonded to the parent part. For example, the complex group alkylamide may represent an alkyl group bonded to the parent molecule via an amide group, and the term alkoxyalkyl may represent an alkoxy group bonded to the parent molecule via an alkyl group.
[0129] When a base is defined as "null," it means that this base does not exist.
[0130] The term "optionally substituted" means that the preceding group may be substituted or unsubstituted.

When a substituent is described without limitation on substitution, both substituted and unsubstituted forms are included. When a substituent is limited to "substituted," the substituted form is specifically intended. Furthermore, different sets of substituents may be defined for a particular part as needed, in which case the optional substitution would often be as defined immediately after the phrase "optionally substituted with."
[0131] The terms R or R', appearing alone and without a number designation, refer to a portion selected from hydrogen, alkyl, cycloalkyl, heteroalkyl, aryl, heteroaryl, and heterocycloalkyl, any of which may be optionally substituted. Such R and R' groups should be understood to be optionally substituted as defined herein. Whether the R group has a number designation or not, R, R', and R n All R groups, all substituents, and all terms, including (where n = (1, 2, 3, ..., n)), should be understood to be independent of all others with respect to selection from the group. If any variable, substituent, or term (e.g., aryl, heterocycle, R, etc.) appears more than once in a formula or general structure, its definition in each appearance is independent of its definition in all other appearances. Those skilled in the art will further recognize that certain groups can be bonded to the parent molecule or occupy a position in the elemental chain from either end as described. For example, an asymmetric group such as -C(O)N(R)- can be bonded to the parent at either carbon or nitrogen.
[0132] The compounds disclosed herein contain chiral centers. These centers are denoted by the symbols "R" or "S" depending on the stereochemistry of substituents around the chiral carbon atom. It should be understood that this disclosure encompasses all stereochemical isomers, including diastereomers, enantiomers, and epimer forms, as well as d-isomers and l-isomers, and mixtures thereof. Individual stereoisomers of compounds can be prepared synthetically from commercially available starting materials containing chiral centers, or they can be prepared by preparing a mixture of enantiomer products, followed by separation such as conversion to a diastereomer mixture, and then by separation or recrystallization, chromatography techniques, direct separation of enantiomers in a chiral chromatography column, or any other suitable method known in the art. Starting compounds for specific stereochemistrys are commercially available or can be prepared and divided by techniques known in the art. Furthermore, the compounds disclosed herein may exist as geometric isomers. This disclosure includes all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers, as well as suitable mixtures thereof. Furthermore, compounds can exist as tautomers, and all tautomers are provided herein.

Generally, the solvated forms are considered equivalent to the non-solvated forms.
[0133] The term "bond" refers to a covalent bond between two atoms, or between two parts when the atoms bonded together are considered part of a larger substructure. Unless otherwise specified, a bond can be a single, double, or triple bond. In molecular diagrams, a dashed line between two atoms indicates that an additional bond may or may not exist at that position.
[0134] As used herein, the term “disease” is intended to be generally synonymous with and interchangeable with the terms “disorder,” “syndrome,” and “condition” (in the case of a medical condition), all of which describe an abnormal condition of one of the body or organs of a human or animal that impairs normal function, is usually manifested by prominent signs and symptoms, and causes a decline in lifespan or quality of life in the human or animal.

See, for example, Das et al., BioTechniques 37:961-969 (2004).
[0139] The phrase "therapeutically effective" is intended to limit the amount of active ingredient used in the treatment of a disease or disorder, or in achieving a clinical endpoint.
[0140] The term "therapeutably acceptable" refers to a compound (or salt, prodrug, tautomer, zwitterionic form, etc.) that is suitable for use in contact with a patient's tissue without excessive toxicity, irritation, or allergic reaction, is balanced by a reasonable benefit / risk ratio, and is effective for its intended use.
[0141] As used herein, references to patient “treatment” are intended to include prevention. Treatment may be preemptive in nature, that is, it may include prevention of disease. Prevention of disease may include complete protection from disease, such as in the case of prevention of infection by a pathogen, or it may include prevention of disease progression. For example, prevention of disease may not mean the complete elimination of any effects associated with disease at any level, but rather may mean preventing the symptoms of disease from reaching a clinically significant or detectable level. Prevention of disease may also mean preventing the disease from progressing to a later stage.
[0142] The term "patient" is generally synonymous with the term "subject" and includes all mammals, including humans. Examples of patients include humans, livestock such as cows, goats, sheep, pigs, and rabbits, as well as companion animals such as dogs, cats, rabbits, and horses. Preferably, the patient is human.
[0143] The term "prodrug" refers to a compound that is more activated in vivo. Certain compounds disclosed herein may also exist as prodrugs, as described in "Hydrolysis in Drug and Prodrug Metabolism: Chemistry, Biochemistry, and Enzymology" (Testa, Bernard and Mayer, Joachim M. Wiley-VHCA, Zurich, Switzerland 2003). Prodrugs of the compounds described herein are structurally modified forms of the compound that readily undergo chemical changes under physiological conditions to provide the compound. Furthermore, prodrugs may be converted to compounds by chemical or biochemical methods in an ex vivo environment. For example, a prodrug may be slowly converted to a compound when placed in a transdermal patch reservoir with appropriate enzymes or chemical reagents. Prodrugs are often useful because, in some situations, they may be easier to administer than the compound or parent drug. For example, a prodrug may be bioavailable by oral administration, even though the parent drug is not. Furthermore, prodrugs may exhibit improved solubility in pharmaceutical compositions compared to their parent drugs. Various types of prodrug derivatives are known in the art, including those that depend on hydrolytic cleavage or oxidative activation of the prodrug. An example (but not limited to) of a prodrug may be a compound that is administered as an ester ("prodrug") but is subsequently metabolically hydrolyzed to a carboxylic acid, which is the active substance. Additional examples include peptidyl derivatives of compounds.
[0144] The compounds disclosed herein may exist as therapeutically acceptable salts. This disclosure includes the above compounds in the form of salts, including acid addition salts. Suitable salts include those formed by both organic and inorganic acids. Such acid addition salts are usually pharmaceutically acceptable. However, salts of pharmaceutically unacceptable salts may be useful in the preparation and purification of the compounds in question. Base addition salts can also be formed and may be pharmaceutically acceptable. For a more complete discussion of salt preparation and selection, see "Pharmaceutical Salts: Properties, Selection, and Use" (Stahl, P. Heinrich. Wiley-VCHA, Zurich, Switzerland, 2002).

[0199] General synthetic methods for preparing compounds The present disclosure can be implemented using the following scheme. Scheme I [Chemical formula] Examples can be synthesized using the general synthetic procedures shown in Scheme I. The synthesis of imidazole I-02 starts from ethylenediamine I-01 having a suitable protecting group represented by the symbol (P), for example a carbamate protecting group. Compound I-01 is reacted with glyoxal and aldehyde R 1 -CHO. The monoiodo compound I-03 is formed by a two-step procedure consisting of the synthesis of a 4,5-diiodoimidazole compound (not shown), followed by selective halogen / metal exchange, and quenching of the resulting organometallic with H + The protecting group is removed (for example, the Boc group is removed with HCl), and a bicyclic structure is obtained by condensation with formaldehyde. The amino group can be functionalized with acetyl chloride (or an equivalent such as acetic anhydride) to obtain amide I-06. The synthesis is completed by Pd(II)-mediated coupling of I-06 with an arylboronic acid or ester to obtain I-07.
[0200] Scheme II [ka] Other examples can be synthesized using the general synthesis procedure shown in Scheme II. The reaction of I-06 with NBS provides a bromo-iodine intermediate II-01, which can be selectively reacted twice under Suzuki coupling conditions to first provide II-02 and then II-03.
[0201] Scheme III [ka] Other examples can be synthesized using the general synthetic procedure shown in Scheme III. Coupling of acid III-01 with pyrazine-2-ylmethaneamine provides amide III-02, which is cyclized to provide imidazopyrazine III-03. Imidazopyrazine III-03 is reduced to imidazopiperazine III-04 by hydrogenation. Imidazopyrazine III-04 reacts with acetyl chloride (or an equivalent such as acetic anhydride) and then with iodine to provide amide III-05. The synthesis is completed by Pd(II)-mediated coupling of III-05 with an arylboronic acid ester or arylboronic acid to obtain III-06.
