Description

[0001] PHARMACEUTICAL COMPOSITION COMPRISING A QUINAZOLINE COMPOUND Field of the Invention The present invention relates to the medical use of compounds, and compositions comprising the compounds, in the treatment of colorectal cancer and / or lung cancer. In particular, the present invention relates to bifunctional compounds comprising a quinazoline or a quinoline heterocycle having a substituent at the 8-position, 2-position or 7-position bound to a ligand of an E3 ligase via a linker, and compounds comprising a group capable of binding to G12D mutant KRAS protein and a Linker-EUB group as defined herein, which have excellent degradation-inducing action on a G12D mutant KRAS protein, and G12D mutant KRAS inhibition activity and their use in the treatment of treating colorectal and / or lung cancer. Background of the Invention The listing or discussion of an apparently prior-published document in this specification should not necessarily be taken as an acknowledgement that the document is part of the state of the art or is common general knowledge. Colorectal cancer is a cancer with a high morbidity and fatality in the world and about 1.4 million new cases are reported per year in the world (World Cancer Report 2014). The most effective means for treating colorectal cancer is a surgery, whereas chemotherapy, radiotherapy, and the like have recently been significantly advanced. Large scale clinical trials performed mainly in Europe and America have revealed that a combination chemotherapy in which several types of anticancer agents are combined is efficacious for colorectal cancer and contributes to regression of a tumor and prolongation of the prognosis (J. Clin. Oncol., 22, p.229-237, 2004). In addition to the chemotherapy, a molecular target drug, such as an anti-VEGF (vascular endothelial growth factor) antibody or an anti-EGFR (epidermal growth factor receptor) antibody, is used as a first-choice drug in combination with the chemotherapy. Regarding an EGFR antibody drug, it has been apparent that mutation in a RAS gene is a negative predictive factor for the effect (Cancer Res., 66, p.3992-3995, 2006), and in colorectal cancer, EGFR antibody drugs are applicable only to patients with wild type RAS genes in the current situation. In addition, the number of death due to lung cancer accounts for 19% of that due to all cancers which is the highest value, and about 1.8 million new patients are reported per year in the world (World Cancer Report 2014). In particular, patients of non-small cell lung cancer (NSCLC) are reported to account for 80 to 85% of those of lung cancer (American Cancer Society, Cancer Facts and Figures, 2016). Surgical therapy is considered until a certain stage, but surgery is rarely adopted after that stage and chemotherapy or radiotherapy then become a main therapy. Based on the cytomorphology, adenocarcinoma and squamous cell cancer are classified as the most typical type of NSCLC. These tumors follow a similar clinical course, but adenocarcinoma is characterized by localization in the lung periphery. RAS proteins are low molecular weight guanosine triphosphate (GTP)-binding proteins of about 21 kDa constituted of 188-189 amino acids, and include four main types of proteins (KRAS (KRAS 4A and KRAS 4B), NRAS and HRAS) produced by three genes of a KRAS gene, an NRAS gene and an HRAS gene. RAS proteins are divided into an active GTP-binding type and an inactive GDP-binding type. A RAS protein is activated by replacement of guanosine diphosphate (GDP) with GTP due to, for example, ligand stimulation to a membrane receptor, such as EGFR. The active RAS binds to effector proteins as much as twenty, such as RAF, PI3K and RALGDS, to activate the downstream signal cascade. On the other hand, the active RAS is converted to the inactive type by replacement of GTP with GDP due to the intrinsic GTP hydrolysis (GTPase) activity. The GTPase activity is enhanced by a GTPase-activating protein (GAP). As can be seen from the above statement, RAS bears an important function of "molecular switch" in an intracellular signal transduction pathway for EGFR or the like and plays a critical role in the processes of cell growth, proliferation, angiogenesis and the like (Nature Rev. Cancer, 2011, 11, p.761-774, Nature Rev. Drug Discov., 2014, 13, p.828-851, Nature Rev. Drug Discov., 2016, 15, p.771-785). Substitution of an amino acid by spontaneous mutation of the RAS gene results in a constant activated state due to hypofunction of RAS as GTPase or hyporeactivity to GAP, and then, signals are continuously sent downstream. The excessive signaling causes carcinogenesis or cancer growth acceleration. In 30 to 40% of the cases of colorectal cancer, a mutation is seen in a KRAS gene and in many cases, the mutation is a spontaneous point mutation particularly in the KRAS exon 2 (codon 12, codon 13) (Ann. Oncol., 27, p.1746-1753, 2016). Effectiveness of existing anticancer agents has not been demonstrated on colorectal cancer with a KRAS mutation, and unmet medical needs for this segment are high. In addition, in lung cancer, a mutation of a RAS gene has been seen in 32% of the cases of lung adenocarcinoma. The breakdown of the frequency of the mutation is 96% in KRAS genes, 3% in NRAS genes, and 1% in HRAS genes, and it is reported that a majority of them are a spontaneous point mutation in the KRAS exon 2 (codon 12, codon 13) (Nature Rev. Drug Discov., 2014, 13, p.828-851). As a mutation of a KRAS gene, KRAS G12D mutation in which glycine at the codon 12 is substituted with aspartic acid and KRAS G12C mutation in which the glycine is substituted with cysteine are particularly known. In recent years, a number of G12C mutant-selective inhibitors have been developed, and among them, Sotorasib has been approved by FDA as a therapeutic agent for non-small cell lung cancer (Drugs, 2021, 81, p.1573-1579). On the other hand, G12D mutant KRAS is seen in about 34% of the cases of pancreatic cancer, in 10% or more of the cases of colorectal cancer, and also in about 4% of the cases of lung adenocarcinoma (Nat. Rev. Cancer, 2018, 18, p.767-777). Thus, a therapeutic agent for a KRAS mutation other than the KRAS G12C mutation is highly expected. WO 2016 / 049565, WO 2016 / 049568 and WO 2017 / 172979 disclose RAS inhibitors, and WO 2016 / 049568 and WO 2017 / 172979 disclose compounds represented by the following formula (A) and formula (B), respectively. Patent Documents WO 2016 / 049565, WO 2016 / 049568 and WO 2017 / 172979 state that the agents are useful for a cancer with a mutation in the codon 12 of KRAS. The G12D mutation is one of such mutations, but any effect on the G12D mutant KRAS-positive cancer is not described. (B) The meanings of the signs in the formulae can be found in the patent documents. Moreover, WO 2021 / 041671, WO 2021 / 106231, WO 2021 / 107160, WO 2022 / 002102, WO 2022 / 015375, WO 2022 / 098625, WO 2022 / 105855 and WO 2022 / 031678 disclose a KRAS G12D inhibitor. Further, Nature 619, 2023, 160–166 discloses a pan-KRAS inhibitor. In recent years, as a technique for inducing degradation of a target protein, bifunctional compounds collectively called as PROTAC (PROteolysis-TArgeting Chimera) or SNIPER (Specific and Nongenetic IAP-dependent Protein Eraser) are found and are expected as one novel technique of drug development modality (Drug. Discov. Today Technol., 2019, 31, p15-27). Such a bifunctional compound promotes formation of a composite of the target protein and an E3 ligase in a cell, and degradation of the target protein is induced using the ubiquitin-proteasome system. The ubiquitin-proteasome system is one of intracellular protein degradation mechanisms. A protein called E3 ligase recognizes a protein to be degraded to convert the protein into ubiquitin, whereby degradation by proteasome is promoted. 600 or more E3 ligases are present in an organism and are roughly divided into four types of HECT-domain E3s, U-box E3s, monomeric RING E3s and multi-subunit E3s. E3 ligases used as a bifunctional degradation inducer which are called PROTAC, SNIPER or the like are currently limited, and typical examples thereof include Von Hippel-Lindau (VHL), celebron (CRBN), inhibitor of apoptosis protein (IAP) and mouse double minute 2 homolog (MDM2). In particular, VHL is reported in WO 2013 / 106643, and CRBN is reported in WO 2015 / 160845. The bifunctional compounds are compounds in which a ligand of a target protein and a ligand of an E3 ligase are bound via a Linker, and some bifunctional compounds for degrading a KRAS protein have ever been reported (Cell. Chem. Biol., 2020, 27, p.19- 31, ACS Cent. Sci., 2020, 6, p.1367-1375, US. 2018 / 0015087, WO 2019 / 195609, WO 2020 / 018788, and WO 2022 / 002102). Further, WO 2023 / 077441 shows bifunctional compounds targeting the G12D mutant KRAS. Summary of the Invention It has now surprisingly been found that compounds of formula (I), (XXI), (XXII) and (XXIII) as defined herein have properties that make them useful in the treatment of lung cancer and / or colorectal cancer. Without wishing to be bound by theory, it is believed that compounds of formula (I), (XXI), (XXII) and (XXIII) as defined herein are useful for treating colorectal cancer and / or lung cancer in view of their degradation-inducing action, for example, on a G12D mutant KRAS protein, and their activity as G12D mutant KRAS inhibitors. In particular, the inventors have found that bifunctional compounds of formula (I), (XXI) and (XXII) comprising a quinazoline or a quinoline heterocycle having a substituent at the 8-position (formula I), 2-position (formula XXI) or 7-position (formula XXII) bound to a ligand of an E3 ligase via a linker, and bifunctional compounds of formula (XXIII) comprising a group capable of binding to G12D mutant KRAS protein and a Linker-EUB group as defined herein, have excellent degradation- inducing action on a G12D mutant KRAS protein, and G12D mutant KRAS inhibition activity and that the compounds are useful (in particular as the active ingredient in a pharmaceutical composition) for treating colorectal and / or lung cancer.

[0047] The compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) may have tautomers or geometrical isomers depending on the type of the substituent. In this specification, the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) is sometimes described only as one of isomers, but the present invention includes isomers other than the above one and includes separated isomers or mixtures thereof. In addition, the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) may have an asymmetric carbon atom or an axial chirality and may have diastereomers based on them. The present invention includes separated diastereomers of the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) or mixtures thereof. Furthermore, the present invention also includes a pharmaceutically acceptable prodrug of the compound represented by the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII). The pharmaceutically acceptable prodrug is a compound having a group which can be converted to an amino group, a hydroxy group, a carboxyl group or the like by solvolysis or under physiological conditions. Examples of a prodrug-forming group include groups described in Prog. Med., 5, p.2157-2161 (1985) or "Pharmaceutical Research and Development" (Hirokawa Publishing Company, 1990), Vol. 7, Molecular Design, p.163-198. In addition, the salt of the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) is a pharmaceutically acceptable salt of the compound of the formula (I) and may be an acid addition salt or a salt formed with a base depending on the type of the substituent. Examples thereof include salts shown in P. Heinrich Stahl, Handbook of Pharmaceutical Salts Properties, Selection, and Use, Wiley-VCH, 2008. Specific examples include an acid addition salt with an inorganic acid, such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, nitric acid or phosphoric acid, or with an organic acid, such as formic acid, acetic acid, propionic acid, oxalic acid, malonic acid, succinic acid, fumaric acid, maleic acid, lactic acid, malic acid, mandelic acid, tartaric acid, dibenzoiltartaric acid, ditoluoyltartaric acid, citric acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, aspartic acid or glutamic acid, a salt with an inorganic metal, such as sodium, potassium, magnesium, calcium or aluminum, a salt with an organic base, such as methylamine, ethylamine or ethanolamine, a salt with various amino acids and amino acid derivatives, such as acetylleucine, lysine or ornithine, an ammonium salt and the like. Furthermore, the present invention also includes various hydrates, solvates and crystal polymorphism substances of the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) and a salt thereof. The present invention also includes all the compounds of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII)or salts thereof which are labeled with one or more pharmaceutically acceptable radioactive or non-radioactive isotopes. Examples of suitable isotopes used for isotopic labeling of the compound of the present invention include isotopes of hydrogen (2H,3H and the like), carbon (11C,13C,14C and the like), nitrogen (13N,15N and the like), oxygen (15O,17O,18O and the like), fluorine (18F and the like), chlorine (36Cl and the like), iodine (123I,125I and the like) and sulfur (35S and the like). The Isotope-labeled compound of the invention of the present application can be used for research and the like such as research on tissue distribution of drugs and / or substrates. For example, radioactive isotopes such as tritium (3H) and carbon 14 (14C) can be used for this purpose due to the easiness of labeling and the convenience of detection. Substitution by a heavier isotope, for example, substitution of hydrogen by deuterium (2H), is therapeutically advantageous through the improvement of metabolic stability in some cases (for example, increase in the in vivo half-life, decrease in the required dose or decrease in the interaction between drugs). Substitution by a positron-emitting isotope (11C,18F,15O,13N or the like) can be used in a positron emission tomography (PET) test for testing occupancy of a substrate receptor. The Isotope-labeled compound of the present invention can be generally produced by a conventional method known to a person skilled in the art or by the same production methods as in the Examples or the Production Examples and the like using suitable reagents which are labeled with an isotope in place of unlabeled reagents.

The compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) is isolated and purified as a free compound, a salt, hydrate, solvate or crystal polymorphous substance thereof or a substance in the amorphous solid form. A salt of the compound of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) can also be produced by subjecting the compound to a salt formation reaction which is an ordinary method.

Pharmaceutical compositions A pharmaceutical composition that contains one or two or more compounds of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) or salts thereof as active ingredients can be prepared by a usually used method using an excipient usually used in the art, namely, a pharmaceutical excipient, a pharmaceutical carrier or the like. The administration may be either oral administration with a tablet, pill, capsule, granule, powder, liquid or other agent or parenteral administration with an intraarticular, intravenous, intramuscular or other injection, a transmucosal agent, an inhalant or the like. As a solid composition for oral administration, a tablet, powder, granular or other agent is used. In such a solid composition, one or two or more active ingredients are mixed with at least one inactive excipient. The composition may contain an inactive additive, for example, a lubricant, a disintegrator, a stabilizer or a dissolution aid, according to an ordinary method. A tablet or pill may be coated with a sugar coating or a film soluble in the stomach or intestine, as needed. Liquid compositions for oral administration include a pharmaceutically acceptable emulsion, solution, suspension, syrup, elixir agent and the like and contain a generally used inactive diluent, for example, purified water or ethanol. The liquid composition may contain, in addition to the inactive diluent, an adjuvant, such as a solubilizer, a wetting agent or a suspending agent, a sweetening agent, a flavor, an aromatic or a preservative. The injection agents for parenteral administration include a sterile aqueous or nonaqueous solution, suspension or emulsion agent. Examples of the aqueous solvent include distilled water for injection or physiological saline. An example of the nonaqueous solvent is an alcohol, such as EtOH. Such a composition may further contain an isotonizing agent, a preservative, a wetting agent, an emulsifier, a dispersant, a stabilizer or a dissolution aid. These are sterilized, for example, by filtration through a bacteria keeping filter, incorporation of a microbicide or irradiation. In addition, such a composition can be produced as a sterile solid composition, which is dissolved or suspended in sterile water or a sterile solvent for injection before use. The transmucosal agent, such as an inhalant or a transnasal agent, is used in a solid, liquid or semi-solid form and can be produced according to a conventionally known method. For example, a known excipient and in addition, a pH modifier, a preservative, a surfactant, a lubricant, a stabilizer, a thickener or the like may be appropriately added. The administration can be performed using an appropriate device for inhalation or insufflation. For example, the agent can be administered using a known device, such as a metering and administering inhalation device, or an atomizer, as a compound alone or a powder of a mixture formulated, or as a solution or a suspension in combination with a medically acceptable carrier. A dry powder inhaler or the like may be for a single administration or multiple administrations, and dry powder or powder-containing capsule can be used. Alternatively, the agent may be used in a form of a pressurized aerosol spray or the like using an appropriate ejection agent, for example, a suitable gas, such as a chlorofluoroalkane or carbon dioxide. In the case of a common oral administration, the daily dose is appropriately about 0.001 to 100 mg / kg body weight, preferably 0.1 to 30 mg / kg body weight, further preferably 0.1 to 10 mg / kg body weight, and the dose is given once or is divided into two to four times in a day. In the case of intravenous administration, the daily dose is appropriately about 0.0001 to 10 mg / kg body weight and is given once or is divided into multiple times in a day. In addition, the daily dose of a transmucosal agent is about 0.001 to 100 mg / kg body weight and is given once or is divided into multiple times in a day. The dose is appropriately decided depending on the individual case taking the symptom, age, sex and the like into account.

EXAMPLES The production method of the compounds of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) will be described in further detail below based on Examples. Note that the present invention is not to be limited to the compounds described in the following Examples. The production methods of raw material compounds are also shown in the Production Examples. Although the compounds described in the following Examples are specific compounds included in the formula (I), the production methods of the compounds of the formula (I) are not limited only to the production methods of specific Examples described below, and the compounds of the formula (I), the formula (XXI), the formula (XXII) or the formula (XXIII) can also be produced by a combination of the production methods or a method that is obvious to a person skilled in the art. Note that, in this specification, a compound is sometimes named using naming software, such as ACD / Name (registered trademark, Advanced Chemistry Development, Inc.). For the purpose of convenience, the concentration mol / L is shown as M. For example, 1 M aqueous sodium hydroxide solution means an aqueous sodium hydroxide solution of 1 mol / L. The "amorphous solid form" described in this specification includes both a form showing no peak in the powder X-ray diffraction (XRD) pattern and a form having a low crystallinity. XRD is measured using Empyrean under the conditions of a vacuum tube of Cu, a tube current of 40 mA, a tube voltage of 45 kV, a step width of 0.013q, a wavelength of 1.5418 Å and a measurement diffraction angle range (2^T) of 2.5 to 40q. Note that due to the nature of the data, crystal lattice spacing and overall pattern are important in determining crystal identity in powder X-ray diffraction patterns, and the error range of the diffraction angle (2 T(q)) in powder X-ray diffraction is usually r0.2q. However, the diffraction angle and diffraction intensity may vary to some extent depending on the crystal growth direction, particle size, and measurement conditions, and should not be interpreted strictly.

Two layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with saturated aqueous sodium chloride solution and was dried over anhydrous magnesium sulfate. The insoluble materials were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane / ethyl acetate), thus obtaining tert-butyl (1S,4S)- 5-{7-bromo-6-cyclopropyl-2-[(2S)-2-methoxypropoxy]-8-[(1S)-1- phenylethoxy]quinolin-4-yl}-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (652 mg) as a foam-like solid.
