Abstract
Description
Technical Field
[0001] The present invention relates to compounds and methods of use thereof. In particular, the compounds of the present invention can be used to inhibit RAS proteins. More specifically, the present invention relates to compounds that inhibit a broad spectrum of KRAS proteins, including mutant and wild-type KRAS. Thus, the compounds of the present invention can be used to treat conditions mediated by KRAS proteins. For example, these compounds can be used to treat cancer. Background Art
[0002] RAS (HRAS, KRAS4A and KRAS4B and NRAS) proteins are a group of closely related monomeric globular proteins that act as molecular switches, cycling between inactive (GDP-bound) and active (GTP-bound) states, transducing upstream cellular signals to downstream effectors to regulate a variety of processes, including cell proliferation. RAS is the most commonly mutated oncogene in cancer (about 30%), and KRAS is the most commonly mutated isoform, accounting for about 85% of RAS mutations (Hobbs et al., Journal of Cell Science (2016) 129, 1287-1292 doi:10.1242 / jcs.182873).
[0003] KRAS G12D is a missense gain of function mutation that results in the substitution of glycine (G) for aspartic acid at codon 12 and is the most prevalent, accounting for approximately 26% of all KRAS mutations in cancer. KRAS G12D mutations are present in 36% of pancreatic cancer patients, 13% of colorectal cancer patients, 10% of rectal cancer patients, 6% of endometrial cancer patients, 4% of non-small cell lung cancer patients, 4% of gastric cancer patients, 3% of ovarian cancer patients, and 2% of small cell lung cancer patients (e.g., The AACR Project GENIEConsortium, (2017) Cancer Discovery; 7(8):818-831. Dataset Version 8). Many of these patients with G12D mutations have a high unmet need and few options for effective targeted therapies. For many of these patients, the mainstay of treatment remains combination chemotherapy, which is associated with a high level of side effects and a lack of efficacy.
[0004] Other KRAS missense gains of KRAS functional mutations that result in amino acid substitutions at codons 12, 13, and 61, as well as amplification of KRAS wild-type proteins, also drive carcinogenesis. KRAS alterations are found in approximately one-seventh of cancers (Hoffman et al., Cancer Discovery (2022) 12, 924-937). KRAS activating mutations are very common in solid tumors and are primarily found in 35% of lung cancers, 45% of colorectal cancers, and up to 90% of pancreatic cancers. G12D, G12V, and G12C are the most common KRAS mutations and are found in more than half of all KRAS-driven cancers. Other KRAS mutations include KRAS G12V, KRAS G12A, KRAS G13D, and KRAS Q61H. KRAS amplification is found in approximately 7% of cancers with KRAS alterations and commonly occurs in ovarian, breast, lung, gastric, uterine, and esophagogastric cancers (reviewed by Hoffman). Pan-KRAS inhibitors have the potential to treat a wider range of patient populations, including cancers harboring KRAS mutations, cancers with KRAS wild-type amplification, and cancers caused by loss of the tumor suppressor NF1. In addition, pan-KRAS inhibitors could potentially be used to treat cancers that have acquired resistance to allele-specific inhibitors, such as KRAS G12C inhibitors.
[0005] Due to the frequency of KRAS mutations in a variety of different tumor types and the established role of KRAS as an oncogenic driver mutation in cancer, modulating the activity of KRAS is a highly attractive therapeutic target and has been the subject of significant research efforts for over 30 years. However, directly affecting KRAS activity has proven extremely challenging, and research efforts have focused on other targets in the signaling cascade upstream or downstream of KRAS. Other approaches to inhibit KRAS activity include affecting other points on the MAPK pathway (English et al., 2002; Adjei 2014; Chin et al., 2020), many of which have shown that MAPK pathway inhibition is clinically effective. Recently, a selective inhibitor of mutant KRAS G12C was reported (Kettle and Cassar 2020) that covalently binds to the allosteric pocket and has advanced to clinical trials and shown responses in selected patients.
[0006] Compounds capable of modulating G12D mutant KRAS are described in WO2021 / 041671. Compounds capable of modulating multiple RAS isoforms and mutants have also been described (Kessler et al., 2019), however, these compounds are considered to have limited therapeutic benefit due to a lack of sufficient potency and minimal selectivity between KRAS and HRAS and NRAS isoforms.
[0007] It is an object of the present invention to provide alternative or improved compounds for inhibiting RAS proteins.For example, it is an object of the present invention to provide alternative or improved compounds for inhibiting KRAS proteins.
[0008] In addition, certain embodiments of the present invention aim to provide novel compounds for treating conditions regulated by RAS proteins. For example, certain embodiments of the present invention aim to provide compounds for treating cancer. Compared to prior art compounds, the compounds are more selective between KRAS proteins with the G12D mutation and alternative KRAS proteins. Alternatively, the compounds may have broad-spectrum activity against a range of KRAS proteins.
[0009] It is an object of certain embodiments of the present invention to provide new methods for treating cancer. In particular, it is an object of certain embodiments of the present invention to provide compounds that have comparable activity to existing treatments, and optionally, they should have better activity.
[0010] It is an object of certain embodiments of the present invention to provide compounds that exhibit reduced cytotoxicity relative to prior art compounds and existing therapies.
[0011] Another object of certain embodiments of the present invention is to provide compounds having convenient pharmacokinetic characteristics and suitable duration of action after administration.Another object of certain embodiments of the present invention is to provide compounds wherein the metabolic fragments after drug absorption are GRAS (generally recognized as safe).
[0012] Certain embodiments of the present invention meet some or all of the above objectives. Summary of the Invention

[0513] (iii) converting one salt of a compound of the present invention into another salt by reaction with a suitable acid or base or by passing through a suitable ion exchange column.
[0514] All three reactions are typically performed in solution. The resulting salt can be precipitated and collected by filtration, or it can be recovered by evaporating the solvent. The degree of ionization of the resulting salt can range from completely ionized to almost non-ionized.
[0515] The compounds of the present invention may exist in unsolvated and solvated forms. The term "solvate" is used herein to describe a molecular complex comprising a compound of the present invention and a stoichiometric amount of one or more pharmaceutically acceptable solvent molecules (e.g., ethanol). When the solvent is water, the term "hydrate" is used.
[0516] Included within the scope of the present invention are complexes such as clathrates and drug-host inclusion complexes, in which, in contrast to the solvates described above, the drug and host are present in stoichiometric or non-stoichiometric amounts. Also included are drug complexes containing two or more organic and / or inorganic components, which may be in stoichiometric or non-stoichiometric amounts. The resulting complexes may be ionized, partially ionized, or non-ionized. For a review of such complexes, see Haleblian, J Pharm Sci, 64(8), 1269-1288 (August 1975).
[0517] Hereinafter, all references to compounds of any formula include reference to salts, solvates and complexes thereof, and to solvates and complexes of their salts.
[0518] The compounds of the present invention include compounds of the numerous formulae as defined herein, including all polymorphs and crystal habits thereof, prodrugs and isomers thereof (including optical isomers, geometric isomers and tautomers) as defined below, and isotopically labeled compounds of the present invention.
[0519] The present invention also includes all pharmaceutically acceptable isotopically labeled compounds of the present invention, wherein one or more atoms are replaced by an atom having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number most commonly found in nature.
[0520] Examples of suitable isotopes for inclusion in the compounds of the present invention include isotopes of hydrogen (e.g. 2 H and 3 H), carbon isotopes (such as 11 C. 13 C and 14 C), isotopes of chlorine (such as 36 Cl), fluorine isotopes (such as 18 F), iodine isotopes (such as 123 I and 125 I), nitrogen isotopes (such as 13 N and 15 N), oxygen isotopes (such as 15 O. 17 O and 18 O), phosphorus isotopes (such as 32 P) and sulfur isotopes (such as 35 S).
[0521] Certain isotopically labeled compounds, for example compounds incorporating radioactive isotopes, are useful in drug and / or substrate tissue distribution studies. 3 H) and carbon-14 (i.e. 14 C) are particularly suitable for this purpose because they are easy to incorporate and have readily available means of detection.
[0522] Using heavier isotopes such as deuterium (i.e. 2 H) substitutions may offer certain therapeutic advantages due to greater metabolic stability, such as increased in vivo half-life or reduced dosage requirements, and therefore may be preferred in some circumstances.
[0523] Before purification, depending on the synthetic procedure used, the compounds of the present invention may exist as mixtures of enantiomers. Enantiomers may be separated by conventional techniques known in the art. Therefore, the present invention encompasses single enantiomers and mixtures thereof.
[0524] For some steps of the method for preparing the compounds of this invention, it may be necessary to protect the potential reactive functional groups that do not wish to react, and therefore the blocking group described in the cracking. In such a case, any compatible protected free radical can be used. Especially, the method for protection and deprotection can be used, as described in TWGREENE (Protective Groups in Organic Synthesis, A.Wiley-Interscience Publication, 1981) or PJKocienski (Protecting groups, Georg Thieme Verlag, 1994). The preparation of all the above-mentioned reactions and the new raw materials used in the aforementioned method is conventional, and reference precedents and examples related thereto and preparation are known to those skilled in the art for the suitable reagents and reaction conditions and the program for separating the required product to realize their performance or preparation.
[0525] Furthermore, the compounds of the present invention and the intermediates used in their preparation can be purified according to various well-known methods, such as crystallization or chromatography.

[0574] Note: Step = step, same below
[0575] General plan 1

In step A, the compound of formula GI-1 can be cyclized with urea or a urea equivalent in the presence of a base (such as sodium hydroxide) or an acid (such as hydrochloric acid) to give a pyrimidine of formula GI-2. In step B, the dihydroxypyrimidine can be chlorinated with phosphorus oxychloride to form a dichloropyrimidine. In step C, the dichloride GI-3 can be reacted with a nucleophile (HZ) in the presence of a base in an anhydrous solvent (such as DCM) at room temperature. 1 R 1 ) to undergo regioselective aromatic nucleophilic substitution. In step D, the remaining chloride of GI-4 can be reacted with HZ under conditions similar to those of step C. 2 R 2Perform a second nucleophilic substitution, or alternatively, Z 2 R 2 It can be introduced by Buchwald coupling with a suitable palladium catalyst. In step E, GI-5 is BOC-deprotected with an acid (such as TFA) to give the secondary amide GI-8. In step F, the amide GI-8 can be reacted with a halo-R by Buchwald coupling with a suitable palladium catalyst. 4 or the corresponding triflate reagent (X = Cl, Br, I or triflate).

Dichloropyrimidine GI-3 can be subjected to boc-deprotection (step E) to form GI-6, followed by a Buchwald reaction (step F) to form GI-9, followed by a sequential nucleophilic substitution of the chloride at the 4-position of the pyrimidine (step C) to form GI-10, and displacement of the chloride at the 2-position of the pyrimidine (step D), and finally (if desired) global deprotection (step G). Alternatively, chloropyrimidine GI-4 can be subjected to boc-deprotection (step E) to form GI-7, followed by a Buchwald reaction (step F) to give chloropyrimidine GI-10, followed by displacement of the chloride at the 2-position of the pyrimidine (step D), and finally (if desired) global deprotection (step G).

In step A, 2-thiomethyl-4,6-dichloropyrimidine of formula GI-11 is reacted in an anhydrous solvent (such as THF or 1,4-dioxane) with a suitable amine or alcohol nucleophile (HZ 1 R 1 ) is subjected to base-mediated regioselective nucleophilic displacement of the chloride at the 4-position to obtain a thiomethyl pyrimidine of formula GI-12. In step B, GI-12 can be subjected to chloride displacement at the 6-position of pyrimidine with a nitrile source (such as Zn(CN)2) in the presence of a Pd catalyst (such as Pd(PPh3)4) to obtain a 2-thiomethyl-6-cyanopyrimidine of formula GI-13. In step C, the thiomethyl of GI-13 can be oxidized to the corresponding methyl sulfone using an oxidant (such as m-CPBA) in a solvent (such as DCM). In the presence of a base (such as NaH), in a solvent (such as DMF or THF), a nucleophile (HZ 2 R 2 ) after nucleophilic displacement, the resulting sulfone is converted to an intermediate of formula GI-14. GI-14 can be treated with hydrogen and a heterogeneous catalyst (such as Pd on carbon) in the presence of an acid (such as 1N HCl) at elevated temperature (such as 50°C). Under these conditions, the amine product of the nitrile hydrogenation can spontaneously cyclize to the adjacent ester group to form an intermediate of formula GI-8. Alternatively, steps C, D, and E can be reordered such that GI-13 undergoes reduction / cyclization (step E) to form GI-15, which is then subjected to thiomethyl oxidation and displacement (steps C and D) to provide the intermediate of formula GI-8.

[0582] General Scheme 3
[0583] The compounds of formula (VII) of the present invention can be prepared by general scheme 3. In step A, compound GI-16 is oxidized with a catalytic oxidant reagent (such as ruthenium trichloride) in the presence of a stoichiometric amount of sodium periodate using EtOAc and water as co-solvents. In step B, dichloride GI-17 can be reacted with a nucleophile (HZ) in the presence of a base in an anhydrous solvent (such as DCM) at room temperature. 1 R 1 ) to undergo regioselective aromatic nucleophilic substitution. In step C, the remaining chloride of GI-18 can be reacted with HZ under conditions similar to step B. 2 R 2 Perform a second nucleophilic substitution, or alternatively, Z 2 R 2It can be introduced by Buchwald coupling with a suitable palladium catalyst. In step D, GI-19 is Boc-deprotected with an acid (such as TFA) to give the secondary amide GI-20. In step E, the amide GI-20 can be coupled with a halo-R4 or a corresponding triflate reagent (X = Cl, Br, I or triflate) by Buchwald coupling with a suitable palladium catalyst. Step F may or may not be required and represents the reaction from R 4 , Z 1 R 1 and Z 2 R 2 A general deprotection step to remove acid labile protecting groups (if present) from reactive atoms on the group, such as R 4 The naphthol OH may contain a methoxymethyl (MOM) protecting group and / or Z 1 R 1 and / or Z 2 R 2 A tert-butyloxycarbamate (Boc) protecting group may be present on the primary or secondary amine, and all of these groups may be removed by treatment with an acid such as TFA.
[0584] Alternatively, steps B to E can be performed in a different order to obtain compounds of formula (VII). Dichloropyrimidine GI-17 can be subjected to boc-deprotection (step D) to form GI-23, followed by a Buchwald reaction (step E) to form GI-24, followed by a sequential nucleophilic substitution of the chloride at the 4-position of the pyrimidine (step B) to form GI-22, and a displacement of the chloride at the 2-position of the pyrimidine (step C), and finally (if desired) a global deprotection (step F). Alternatively, chloropyrimidine GI-18 can be subjected to boc-deprotection (step D) to form GI-21, followed by a Buchwald reaction (step E) to give chloropyrimidine GI-22, followed by a displacement of the chloride at the 2-position of the pyrimidine (step C), and finally (if desired) a global deprotection (step F).
