CYSTEINE COVALENT MODIFIERS OF AKT1 AND USES THEREOFCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 590,256 filed on October 13, 2023, U.S. Provisional Application No. 63 / 562,578 filed on March 7, 2024, and U.S. Provisional Application No. 63 / 686,523 filed on August 23, 2024, the entirety of each is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] The AKT or Protein Kinase B (PKB) family of serine / threonine protein kinases is comprised of 3 highly homologous members, AKT1, AKT2 and AKT3. The family of AKT proteins are involved in signal transduction pathways that regulate cellular processes including apoptosis, proliferation, differentiation, and metabolism. The AKT1 pathway is the most frequently dysregulated signaling pathways in human cancers. Enhanced activation of all the isoforms can be implicated in tumor development and progression, and has been demonstrated in breast, ovarian, pancreatic, and prostate cancers among others (Song et al., 2019). In cancer cells, AKT1 is involved in proliferation and growth, promoting tumor initiation, and suppressing apoptosis, whereas AKT2 regulates cytoskeleton dynamics, favoring local tissue invasion and metastasis. The role of AKT3 hyperactivation in cancer is hypothesized to be involved with possible stimulation of cell proliferation (Hinz et al., Cell Commun Signal 2019, 17(1), 154; Pascual et al., Ann. Oncol. 2019, 30(7), 1051-1060). Expression of these AKT family members is altered in many human malignant carcinomas including gastric, breast, prostate, ovarian, and pancreatic. AKT family members are rarely mutated however, the most common mutation is AKT1 E17K which has been reported in 6-8% of breast cancers, 2-6% of colorectal cancers, and in 6% of meningiomas, in humans (Yu et al., PLoS One 2015, 10 (10), No. e0140479). Thus, there is a need to develop new treatments for the modulation of AKT1 and mutants thereof.SUMMARY OF THE INVENTION

[0018] The AKT or Protein Kinase B (PKB) family of serine / threonine protein kinases regulate a myriad of key cellular functions, including apoptosis, proliferation, differentiation, and metabolism. The AKT family is comprised of 3 highly homologous members, AKT1, AKT2 and AKT3, and each member possesses a unique tissue distribution and may perform a uniqueset of biological functions. Aberrant expression and / or activation of all AKT isoforms has been implicated in tumor development, including breast, ovarian, pancreatic, and prostate cancers among others.

[0019] Inhibitors of AKT proteins have been developed for the treatment of cancer, including the two major classes of small-molecule AKT inhibitors being investigated in the clinic: allosteric and ATP-competitive inhibitors. First, allosteric inhibitors (such as miransertib (ARQ 092) and MK-2206) interfere with PH-domain mediated membrane recruitment (the first step in AKT activation) and inhibit AKT kinase activation and AKT phosphorylation. Second, ATP- competitive inhibitors of AKT (such as ipatasertib and capivasertib) bind to the active kinase, in which the PH-domain has shifted from the kinase domain and exposed the ATP -binding pocket site, thus inhibiting ATP binding.

[0020] Provided herein are compounds for modulating (e.g., inhibiting) AKT1 function, as well as methods and compositions for using compounds of the present disclosure in the treatment of cancer. In some embodiments, the compounds selectively inhibit (e.g., 2x, 5x, lOx, 50x, lOOx, etc.) an AKT1 protein over an AKT2 and / or AKT3 protein.Definitions

[0240] In some embodiments, the compound or salt of Formula (I), (I- A), (II), (II- A), (III), (III-A), or (III-B) is a compound of Table 1. * Denotes a stereocenter with an undetermined absolute stereochemistry of a single isomer.

[0241] Table 1. Chemical structures of selected compounds.

[0242] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.

[0243] Chemical entities having carbon-carbon double bonds or carbon-nitrogen double bonds may exist in Z- or E- form (or cis- or trans- form). Furthermore, some chemical entities may exist in various tautomeric forms. Unless otherwise specified, compounds or salts of Formula(I), (I- A), (II), (II- A), (III), (III-A), or (III-B), are intended to include all Z-, E- and tautomeric forms as well.

[0244] “ Isomers” are different compounds that have the same molecular formula.“Stereoisomers” are isomers that differ only in the way the atoms are arranged in space. “Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1 : 1 mixture of a pair of enantiomers is a “racemic” mixture. The term “(±)” is used to designate a racemic mixture where appropriate. “Diastereoisomers” or “diastereomers” are stereoisomers that have at least two asymmetric atoms but are not mirror images of each other. The absolute stereochemistry is specified according to the Cahn-Ingold-Prelog R-S system. When a compound is a pure enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro- or levorotatory) in which they rotate plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms, the asymmetric centers of which can be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible stereoisomers, including racemic mixtures, optically pure forms, mixtures of diastereomers and intermediate mixtures. Optically active (R)- and (S)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. The optical activity of a compound can be analyzed via any suitable method, including but not limited to chiral chromatography and polarimetry, and the degree of predominance of one stereoisomer over the other isomer can be determined.

[0245] The compounds or salts for Formula (I), (I-A), (II), (II-A), (III), (III-A), or (III-B), herein may in some cases exist as diastereomers, enantiomers, or other stereoisomeric forms. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as the racemates, mixtures of diastereomers, and other mixtures thereof, to the extent they can be made by one of ordinary skill in the art by routine experimentation. Separation of stereoisomers may be performed by chromatography or by forming diastereomers and separating by recrystallization, or chromatography, or any combination thereof. (Jean Jacques, Andre Collet, Samuel H. Wilen, “Enantiomers, Racemates and Resolutions,” John Wiley And Sons, Inc., 1981, herein incorporated by reference for this disclosure). Stereoisomers may also be obtained by stereoselective synthesis. Furthermore, a mixture of two enantiomers enriched in one of the two can be purified to provide further optically enriched form of the major enantiomer by recrystallization and / or trituration.

[0246] In certain embodiments, compounds or salts for Formula (I), (I- A), (II), (II- A), (III), (III-A), or (III-B), may comprise two or more enantiomers or diastereomers of a compound wherein a single enantiomer or diastereomer accounts for at least about 70% by weight, at least about 80% by weight, at least about 90% by weight, at least about 98% by weight, or at least about 99% by weight or more of the total weight of all stereoisomers. Methods of producing substantially pure enantiomers are well known to those of skill in the art. For example, a single stereoisomer, e.g., an enantiomer, substantially free of its stereoisomer may be obtained by resolution of the racemic mixture using a method such as formation of diastereomers using optically active resolving agents (Stereochemistry of Carbon Compounds, (1962) by E. L. Eliel, McGraw Hill; Lochmuller (1975) J. Chromatogr., 113(3): 283-302). Racemic mixtures of chiral compounds can be separated and isolated by any suitable method, including, but not limited to: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and (3) separation of the substantially pure or enriched stereoisomers directly under chiral conditions. Another approach for separation of the enantiomers is to use a Diacel chiral column and elution using an organic mobile phase such as done by Chiral Technologies (www.chiraltech.com) on a fee for service basis.

[0247] A “tautomer” refers to a molecule wherein a proton shift from one atom of a molecule to another atom of the same molecule is possible. In certain embodiments, the compounds or salts for Formula (I), (I-A), (II), (II-A), (III), (III-A), or (III-B), exist as tautomers. In circumstances where tautomerization is possible, a chemical equilibrium of the tautomers may exist. The exact ratio of the tautomers depends on several factors, including physical state, temperature, solvent, and pH. Some non-limiting examples of tautomeric equilibrium include:

[0248] The compounds disclosed herein, in some embodiments, are used in different enriched isotopic forms, e.g., enriched in the content of2H,3H,nC,13C and / or14C. In one particular embodiment, the compound may be deuterated in at least one position. Such deuterated forms can be made by the procedure described in U.S. Patent Nos. 5,846,514 and 6,334,997. As described in U.S. Patent Nos. 5,846,514 and 6,334,997, deuteration can improve the metabolic stability and or efficacy, thus increasing the duration of action of drugs.

[0249] In certain embodiments, the compounds disclosed herein have some or all of theJH atoms replaced with2H atoms. The methods of synthesis for deuterium-containing compounds are known in the art and include, by way of non-limiting example only, the following synthetic methods.

[0250] Deuterium substituted compounds are synthesized using various methods such as described in: Dean, Dennis C.; Editor.

Large numbers of deuterium-containing reagents and building blocks are available commercially from chemical vendors, such as Aldrich Chemical Co.

[0252] Unless otherwise stated, compounds described herein are intended to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by13C- or14C-enriched carbon are within the scope of the present disclosure.

[0253] The compounds of the present disclosure optionally contain unnatural proportions of atomic isotopes at one or more atoms that constitute such compounds.
