[0002] Kirsten rat sarcoma viral oncogene homologs (KRAS) are a group of genes responsible for making K-Ras proteins, which are important for cell growth and proliferation. Many mutations in KRAS are involved in many different types of cancer. One mutation, in particular, KRAS G12D, is a common oncogenic KRAS mutation and presents a promising target for the treatment of solid tumors associated with the KRAS pathway. Much research has been done to identify binding pockets, such as the switch II pocket, for irreversible inhibition of KRAS harboring the corresponding KRAS G12C mutation (MA, Marx et al., Identification of the Clinical Development Candidate MRTX849, a Covalent KRASG12C Inhibitor for the Treatment of Cancer. J. Med. Chem. 2020, 63(13), 6679-6693; VJ, Cee et al., Discovery of a Covalent Inhibitor of KRASG12C (AMG 510) for the Treatment of Solid Tumors. J. Med. Chem. 2020, 63(1), 52-65; X. Lu et al., Small-Molecule Inhibitors Directly Targeting KRAS as Anticancer Therapeutics. J. Med. Chem. 2020, 63(23), 14404-14424). However, KRAS G12D lacks the reactive residues adjacent to the switch II pocket present in KRAS G12C.Several studies have attempted to develop a new class of drugs that bind to the shallow pocket between switch I and switch II of KRAS G12D (G. Fang, et al., Small-Molecule Ligands Bind to a Distinct Pocket in RAS and Inhibit SOS-Mediated Nucleotide Exchange Activity. Proc. Natl. Acad. Sci. USA, 2012, 109(14), 5299-5304; SW, Fesik, et al., Discovery of Small Molecules that Bind to K-RAS and Inhibit SOS-Mediated Activation. Angew. Chem., Int. Ed. 2012, 51(25), 6140-6143), but limited cellular activity has been observed. Recently, a small molecule known as MRTX1133 was discovered that binds to the switch II pocket of KRAS G12D. MRTX1133 is a potent, selective, noncovalent inhibitor of KRAS G12D that exhibits picomolar binding affinity, low nanomolar activity in cellular assays, and in vivo efficacy in tumor models harboring KRAS G12D mutations (MAMarx et.al., Identification of MRTX1133, a Noncovalent, Potent, and Selective KRASG12D Inhibitor. J. Med. Chem., 2022, 65(4), 3123-3133).

[0003] Proteolytic targeting chimeras (PROTACs) are bifunctional molecules containing two active domains, colloquially known as "warheads," covalently linked to each other by a linking moiety (Hodges et al., Next-Generation Drugs and Probes for Chromatin Biology: From Targeted Protein Degradation to Phase Separation. Molecules. 23(8), 1958). One such PROTAC that targets KRAS G12C is the molecule LC-2. LC-2, based on the KRAS G12C inhibitor MRTX849, can rapidly degrade KRAS G12C in homozygous and heterozygous tumor cells (M. J. Bond et al., Target degradation of oncogenic KRAS G12C by VHL-recruiting PROTACs, ACS Cent. Sci., 2020, 6, 1367-1375; J. Halin et al., The KRAS (G12C) inhibitor MRTX849 provides insight toward therapeutic susceptibility of KRAS-mutant cancers in mouse models and patients. Cancer Discov. 10, 54-71). However, because LC-2 is a covalent inhibitor of KRAS G12C, it remains bound to its target protein, which can affect the catalytic cycle of the PROTAC molecule and thereby limit its efficacy. Thus, there remains a need for PROTACs that are capable of binding to KRAS G12D and inducing its degradation, preferably in a non-covalent manner. [Prior art documents] [Non-patent literature]

[0040] The term "substituted" refers to the replacement of a hydrogen atom with a suitable substituent. Typically, a suitable substituent replaces a hydrogen atom bonded to a carbon atom, but a substituent can also replace a hydrogen atom bonded to a heteroatom, such as a nitrogen atom. When two or more hydrogen atoms are each replaced with independently selected substituents, the substituents can be the same or different. It will be understood that "substituted" or "substituted with" includes the implicit condition that such substitution is in accordance with the allowed valence of the substituted atom. It is also preferred that the substituents and substitutions result in stable compounds that do not spontaneously undergo transformation, for example, by rearrangement, migration, elimination, etc.

[0041] The term "optionally substituted," as used herein, means that substitution is optional, and thus the atom or moiety designated as "optionally substituted" can be unsubstituted or substituted. In some embodiments, an optionally substituted group is unsubstituted. In some embodiments, an optionally substituted group is substituted. An "optionally substituted" group is, in some embodiments, substituted with 0 to 5 (e.g., 1 to 5, 0 to 3, 1-3, 0, 1, 2, 3, 4, 5) substituents. Unless otherwise indicated, groups designated herein are unsubstituted, as for example, by the term "substituted" or "optionally substituted" groups.

[0042] The bond to the substituent may be such that it crosses the bond connecting two atoms in the ring (e.g., R 1 , R 6 and R 8When a substituent is shown crossing a bond to a substituent (a bond to a ring) or a circle representing a ring, then such substituent may be bonded to any substitutable atom in the ring. Further, when the ring in which a bond to a substituent is shown crossing is polycyclic (e.g., bicyclic, e.g., the hexahydropyrrolidinyl ring system in Structural Formula II), then the substituent may be bonded to any substitutable atom in the ring or ring system in which a bond to a substituent is shown crossing.

[0043] When a substituent is listed or shown without indicating the atom to which such substituent is attached to the remainder of a compound of a given formula, then such a substituent may be attached through any atom in such a substituent, as long as such substitution results in a stable compound. Square brackets are used herein to indicate such a substituent without indicating the atom to which such a substituent is attached to the remainder of a compound of a given formula. Thus, for example, a compound of the following structural formula: [ka] wherein the portion of the compound in the square brackets attached to -L'-[Degron] is a compound of the following structural formula: [ka] through the nitrogen atom of the secondary amine of the diazabicyclooctanyl moiety, or to give a compound of the following structural formula: [ka] Similarly, a compound of the following structural formula: [KRAS G12Di]-L'-[Degron], where Degron is [ka] In the above formula, Degron is, for example, [ka] or via the ortho carbon atom of the phthalimide, as in [ka] These examples are given for illustrative purposes only and are not limiting of other attachment sites on the Degron and / or on the moiety in the compound in square brackets that is attached to -L'-[Degron], all of which are contemplated by the present disclosure.

[0044] Suitable substituents for use herein include halogen, hydroxyl, carbonyl (e.g., carboxyl, alkoxycarbonyl, formyl, or acyl), thiocarbonyl (e.g., thioester, thioacetate, or thioformate), alkyl, alkoxy, alkylthio, acyloxy, phosphoryl, phosphate, phosphonate, amino, amido, amidine, imine, cyano, nitro, azido, sulfhydryl, alkylthio, sulfate, sulfonate, sulfamoyl, sulfonamido, sulfonyl, cycloalkyl, heterocyclyl, aralkyl, aryl, or heteroaryl. It will be understood by those skilled in the art that the substituents may themselves be substituted, if appropriate. Thus, the substituent may further include, for example, acetamide.

[0045] When a divalent substituent is recited without indicating any directionality of such substituent (e.g., variables L′ and / or X), the divalent substituent may be attached in either direction. Thus, for example, a compound of structural formula (I): [ka] (Wherein L' is -X-(CH2) q -) has the following structural formula: [ka] and the following structural formula: [ka] Both compounds are included.

[0046] As used herein, the term "compounds of the present disclosure" refers to compounds of any structural formula set forth herein (e.g., compounds of structural formula I or subformulas thereof, e.g., compounds of structural formula Ia, Ib, II, IIa, IIb, III, IIIa, IIIb, IV, IVa, IVb, V, Va, Vb, Table 1), as well as isomers, e.g., stereoisomers (including diastereoisomers, enantiomers, and racemates) and tautomers thereof, isotopologues thereof, and inherently formed moieties thereof (e.g., polymorphs and / or solvates, e.g., hydrates). If moieties capable of forming salts are present, then salts, particularly pharmaceutically acceptable salts, are also included.

[0047] The compounds of the present disclosure have asymmetric centers, chiral axes, and chiral planes (as described, for example, in E.L. Eliel and S.H. Wiley, Stereo-chemistry of Carbon Compounds, John Wiley & Sons, New York, 1994, pages 1119-1190) and can occur as racemic mixtures, individual isomers (e.g., diastereomers, enantiomers, geometric isomers (including cis and trans double bond isomers), conformational isomers (including rotamers and atropisomers), tautomers, and intermediate mixtures; all possible isomers and mixtures thereof are included unless otherwise indicated.

[0048] Unless otherwise indicated in terms of use herein, when a disclosed compound or moiety is depicted by a structure without indicating stereochemistry, and the compound or moiety has one or more chiral centers, the structure should be understood to encompass one enantiomer or diastereomer of the compound or moiety separated or substantially separated from the corresponding optical isomer(s), racemic mixtures, and mixtures enriched in one enantiomer or diastereomer relative to its corresponding optical isomer(s).Unless otherwise indicated in terms of use herein, when a disclosed compound or moiety is depicted by a structure using solid and / or broken wedges to indicate stereochemistry, and the compound or moiety has one or more chiral centers, the stereochemistry indicates the absolute configuration of substituents around the one or more chiral centers. Unless otherwise indicated in terms of use herein, disclosed compounds or moieties are depicted by structures using solid and / or broken bold lines to indicate stereochemistry, and where a compound or moiety has one or more chiral centers, stereochemistry refers to the relative stereochemistry of the unspecified absolute configuration of substituents around one or more chiral centers. "R" and "S" can also or alternatively be used to indicate the absolute configuration of substituents around one or more chiral centers (e.g., carbon atoms). D- and L- can also or alternatively be used to designate stereochemistry. Thus, for example, a single stereoisomer having known relative and absolute configurations of two chiral centers can be designated using the conventional RS system (e.g., (1S,2S)); diastereomers in a racemic mixture can be designated using the two-letter RS ​​system (e.g., (1RS,2RS) for a racemic mixture of (1R,2R) and (1S,2S); (1RS,2SR) for a racemic mixture of (1R,2S) and (1S,2R)).

[0049] "Enantiomers" are a pair of stereoisomers that are non-superimposable mirror images of each other, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center.

[0050] "Diastereomers" are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms.

[0051] As used herein, a "racemate" or "racemic mixture" refers to a mixture containing equimolar amounts of two enantiomers of a compound. Such mixtures do not exhibit optical activity (i.e., they do not rotate the plane of polarized light).

[0052] Enantiomeric excess (ee) is defined as the absolute difference between the mole fractions of each enantiomer multiplied by 100% and is calculated using the following equation:

number

[0053] Diastereomeric excess (de) is defined as the absolute difference between each mole fraction of each diastereomer multiplied by 100% and is calculated using the following equation:

number

[0054] Tautomers are isomers of a compound that differ in the location of one or more hydrogen atoms.

[0055] Unless otherwise indicated, all possible isomers and mixtures thereof, including optical isomers, rotamers, tautomers and cis and trans isomers, are included in the present invention.

[0056] The term "isotopologue" refers to a molecule that differs from a reference molecule only in its isotopic composition.

[0057] A given atom naturally exists in various isotopic forms. Natural isotopic abundance refers to the relative abundance of various naturally occurring isotopes of a given atom. Thus, it is understood that a population of molecules represented by a particular chemical structure will typically contain isotopologues of the particular chemical structure. The relative amount of such isotopologues will depend on numerous factors, such as the relative natural isotopic abundance, the isotopic purity of the reagents used to make the compound, and the efficiency of incorporation of isotopic atoms in the various synthetic steps used to prepare the compound. In certain embodiments, the amount of such isotopologues will be less than 49.9%, e.g., less than 47.5%, less than 40%, less than 32.5%, less than 25%, less than 17.5%, less than 10%, less than 5%, less than 3%, less than 1%, or less than 0.5% overall.

[0058] The structures depicted herein are meant to represent such natural isotopic abundances, as well as the replacement of one or more atoms in the structure with its isotopically or isotopically enriched counterpart, e.g., at non-natural isotopic abundances, e.g., hydrogen with deuterium or tritium, or 13 C or 14 Compounds produced by replacement of carbon with C are within the scope of the present disclosure. In some embodiments, a hydrogen atom in a compound of the present disclosure is replaced or enriched with D. In some embodiments, a methyl group in a compound of the present disclosure is replaced or enriched with -CD. Isotopologues can be useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents according to the present disclosure.

[0059] The phrase "pharmaceutically acceptable" means that the substance or composition it modifies is, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit / risk ratio.

[0060] As used herein, the term "pharmaceutically acceptable salt" refers to those salts that are, within the scope of reasonable medical judgment, suitable for use in contact with mammalian tissues without undue toxicity, irritation, allergic response, etc., and that are commensurate with a reasonable benefit / risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S.M. Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19 (the relevant teachings of which are incorporated herein by reference in their entirety).

Further pharmaceutically acceptable base addition salts include non-toxic ammonium, quaternary ammonium, and amine cations formed, where appropriate, using counterions such as halides, hydroxides, carboxyls, sulfates, phosphates, nitrates, lower alkyl sulfonates, and aryl sulfonates.

[0063] The compounds described herein may also exist as "solvates" or "hydrates." A "hydrate" is a compound that exists in a composition with one or more water molecules. A hydrate may contain a stoichiometric amount of water, such as a monohydrate or dihydrate, or may contain a random amount of water. A "solvate" is similar to a hydrate, except that a solvent other than water, such as methanol, ethanol, dimethylformamide, diethyl ether, etc., replaces water. Mixtures of such solvates or hydrates may also be prepared. The source of such solvates or hydrates may be from the solvent of crystallization, inherent in the solvent of preparation or crystallization, or adventitious to such solvent.

[0064] "Pharmaceutically acceptable carrier" refers to a non-toxic carrier or excipient that does not destroy the pharmacological activity of the drug formulated therewith and is non-toxic when administered in a dose sufficient to deliver a therapeutic amount of the drug. Pharmaceutically acceptable carriers that can be used in the compositions described herein include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinylpyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylate, wax, polyethylene-polyoxypropylene-block polymers, polyethylene glycol, and wool fat.

[0065] "Treating," as used herein, refers to using a process to deliver therapy to a subject, e.g., a mammal, in need thereof (e.g., by administering one or more therapeutic agents to the subject). "Treating" includes inhibiting a disease or condition (e.g., by slowing or stopping its progression or by causing regression of the disease or condition), as well as alleviating symptoms caused by the disease or condition.

[0066] "KRAS G12D" refers to a mammalian KRAS protein containing an aspartic acid substitution for glycine at amino acid position 12. The amino acid codon and residue position assignments for human KRAS are based on the amino acid sequence specified by UniProtKB / Swiss-Prot P01116:Variantp.Gly12Asp.

[0067] "KRAS G12D-associated cancer" refers to a cancer that is associated with (e.g., mediated by) or has a KRAS G12D mutation. Those skilled in the art will know how to determine (e.g., diagnose) whether a cancer or a subject has a KRAS G12D mutation, for example, by using a kit or assay approved by a regulatory authority, such as the U.S. Food and Drug Administration (FDA). Techniques that can be used to determine whether a cancer or a subject has a KRAS G12D mutation include next-generation sequencing, immunohistochemistry, fluorescence microscopy, break-apart FISH analysis, Southern blotting, Western blotting, FACS analysis, Northern blotting, and PCR-based amplification (e.g., RT-PCR).

[0068] " Binding site " is the part of a compound that binds to the indicated target with measurable affinity.In the context of the present disclosure, the target can typically be a protein, for example, KRAS G12D in KRAS G12D binding site; ubiquitin E3 ligase in ubiquitin E3 ligase binding site.In the compound of the present disclosure, the binding of the compound of the present disclosure to the indicated target is typically mediated by the binding site of the target.For example, the binding of the compound of the present disclosure to KRAS G12D in the compound of the present disclosure is typically mediated by KRAS G12D binding site.For example, the binding of the compound of the present disclosure to ubiquitin E3 ligase is typically mediated by ubiquitin E3 ligase binding site.

[0069] Binding (of the binding site and / or compound of the present disclosure) to a target can result, for example, in inhibition and / or agonism (full or partial) of the target, e.g., a target protein. Thus, in some embodiments, the binding site and / or compound of the present disclosure is an inhibitor. In certain embodiments, the binding site and / or compound of the present disclosure has an IC for its indicated target of less than about 50 μM, e.g., less than about 10 μM, less than about 5 μM, less than about 1 μM, less than about 500 nM, less than about 100 nM, less than about 10 nM, or less than about 1 nM. 50 and / or have the binding constant with its indicated target, IC 50and methods for determining binding constants are described herein and / or are within the capabilities of one of ordinary skill in the art.

[0070] An "effective amount" is an amount effective, at dosages and for periods of time necessary, to achieve a desired result (eg, a desired therapeutic result, a desired in vitro result).

[0071] A "therapeutically effective amount" is an amount effective, at dosages and for periods of time necessary, to achieve a desired therapeutic result (e.g., treating, curing, inhibiting, or ameliorating a physiological response or condition, etc.). A full therapeutic effect does not necessarily occur by administration of a single dose, but may occur only after administration of a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations. A therapeutically effective amount may vary depending on factors such as the disease state, age, sex, and weight of the mammal, the mode of administration and the ability of the therapeutic agent, or combination of therapeutic agents, to elicit a desired response in an individual. The therapeutically effective amount of the agent to be administered can be determined by a clinician of ordinary skill using the guidance provided herein and other methods known in the art.

[0072] As used herein, a "subject" includes humans, domesticated animals, such as laboratory animals (e.g., dogs, monkeys, pigs, rats, mice, etc.), household pets (e.g., cats, dogs, rabbits, etc.) and livestock (e.g., pigs, cows, sheep, goats, horses, etc.), and non-domesticated animals. In some embodiments, the subject is a human.

[Table 4-1] [Table 4-2] [Table 4-3] [Table 4-4] [Table 4-5] [Table 4-6] [Table 4-7] [Table 4-8] [Table 4-9] [Table 4-10] [Table 4-11] [Table 4-12] [Table 4-13] [Table 4-14] [Table 4-15] [Table 4-16] [Table 4-17] [Table 4-18] [Table 4-19] [Table 4-20] [Table 4-21] [Table 4-22] [Table 4-23] [Table 4-24] [Table 4-25]

[0173] From the foregoing, for example, unless specified by "*", values ​​for L' are asymmetric (e.g., -C(O)N(H)-, -C(O)N(H)-(CH2) 3,4,6,8,9,10- N(H)-, -C(O)N(H)-(CH2) 2,3,4,5,9,10,11- , -C(O)N(H)-(CH2CH2O) 2,3In the case of -CHCH-N(H)-), it will be understood that the value can be oriented in either direction between KRASG12Di and Degron.

[0174] Degron Degrons bring a ligase enzyme into proximity with the target protein, allowing the protein to be labeled with a ubiquitin tag and targeted for degradation by the ubiquitin-proteasome system.

[0175] "Degron," as used herein, refers to a moiety that, under suitable conditions (e.g., in vitro, in vivo), is capable of promoting degradation of a target protein, such as KRAS G12D, via the ubiquitin proteasome pathway (UPP). Typically, in a PROTAC, e.g., a compound of the present disclosure, the degron is capable of binding a ubiquitin E3 ligase, thereby recruiting the ubiquitin E3 ligase to the vicinity of the PROTAC and, by extension, the target protein that is bound to KRAS G12D in the compound of the present disclosure, under suitable conditions. Formation of the ternary ligase-PROTAC-target protein complex results in ubiquitination and degradation of the target protein, e.g., by the 26S proteasome, a component of the UPP. Thus, examples of degrons include a ubiquitin E3 ligase binding site that binds to a ubiquitin E3 ligase. Examples of E3 ligases include cereblon (CRBN), von Hippel-Lindau (VHL), inhibitor of apoptosis proteins (IAPs), mouse double minute 2 homolog (MDM2), DDB1 and CUL4-associated factor 16 (DCAF16), and ring finger protein 114 (RNF114). Other examples of degrons include hydrogen atom and lysine mimetics, both of which are disclosed in International Publication No. WO 2021 / 127278, the entire contents of which are incorporated herein.

[0176] In some aspects (e.g., of any of the foregoing embodiments, aspects, or combinations of aspects), the Degron is a ubiquitin E3 ligase binding site (e.g., a cereblon binding site). In further aspects, the ubiquitin E3 ligase is CRBN, VHL, IAP, MDM2, DCAF16, or RNF114. In still further aspects, the ubiquitin E3 ligase is CRBN, such that the ubiquitin E3 ligase binding site is a cereblon binding site. Thus, in some aspects, the Degron is a cereblon binding site.

[0177] Ubiquitin E3 ligase binding sites, including cereblon binding sites, are disclosed in International Publication No. WO2021 / 127278. See, e.g., Table A therein. In some aspects (e.g., of any of the foregoing embodiments, aspects, or combinations of aspects), the Degron is a ubiquitin E3 ligase binding site (e.g., a cereblon binding site) disclosed in WO2021 / 127278.
