Abstract
Description
[Technical Field]
[0001] This application claims priority to Chinese Patent Application No. CN201911386239.6, filed on 27 December 2019, and Chinese Patent Application No. CN202010486384.8, filed on 1 June 2020, the contents of which are incorporated in their entirety by reference.
[0002] Technical field The present invention belongs to the field of medicinal chemistry, and more particularly to spiroring-containing quinazoline compounds, methods for preparing the same, and methods for using the said compounds as K-Ras G12C inhibitors in the preparation of antitumor drugs. [Background technology]
[0003] background Members of the Ras protein family are important signaling molecules within cells, playing crucial roles in growth and development. Extensive analyses and studies of in vitro tumor cells, animal models, and human tumor samples have shown that hyperactivation of Ras family proteins is an early event in human tumor development and a significant cause of development and progression in many types of cancer. Therefore, targeting Ras proteins and inhibiting their activity is an important means of treating related tumors.
[0004] The Ras protein exists in two forms. It is in a dormant state when bound to GDP, and becomes activated when cells receive signals such as growth factor stimulation, by binding to GTP. Activated Ras proteins recruit various signaling adapter proteins to activate the Ras signaling pathway, regulating cell proliferation, survival, migration, and differentiation by promoting the phosphorylation of downstream signaling molecules such as ERK and S6. Due to its GTPase activity, the Ras protein can hydrolyze GTP back to GDP. Furthermore, intracellular GTPase-activating proteins (GAPs) interact with Ras, significantly increasing its GTPase activity and thereby preventing overactivation of the Ras protein.
[0005] Mutations in the K-Ras, H-Ras, and N-Ras proteins of the Ras protein family are common genetic mutations in various tumors and are a major cause of Ras protein overactivation in tumors. Ras proteins with these mutations are less regulated in activity compared to wild-type Ras proteins, and are constantly activated by stably binding to GTP, thus promoting tumor cell proliferation, migration, and differentiation. Of these mutations, K-Ras protein mutations are the most common, accounting for 85% of all Ras mutations, while N-Ras (12%) and H-Ras (3%) mutations are relatively rare. K-Ras mutations are very common in many types of cancer, including pancreatic cancer (95%), colorectal cancer (45%), and lung cancer (25%), but are relatively rare (less than 2%) in breast cancer, ovarian cancer, and brain tumors. K-Ras mutations mainly occur at position G12, with G12C mutations being the most common. For example, in non-small cell lung cancer (NSCLC), approximately 50% of K-Ras mutations are K-Ras G12C, with G12V and G12D being the second most common mutations. Genomic studies suggest that K-Ras mutations in NSCLC generally do not coexist with EGFR, ALK, ROS1, RET, or BRAF mutations, but coexist with mutations such as STK11, KEAP1, and TP53, suggesting that K-Ras mutations may synergistically contribute to cell malignancy, proliferation, and invasion in conjunction with mutations such as STK11, KEAP1, and TP53. Beyond tumors, abnormal activation of the Ras protein is also involved in non-tumor diseases such as diabetes and neurodegenerative diseases. Therefore, small molecule compounds targeting the Ras protein may benefit many cancer patients with specific gene mutations and non-cancer patients with overactivation of the Ras pathway.
[0006] Since the discovery of Ras mutations in tumors 40 years ago, progress has been made in elucidating the pathological conditions involving the Ras pathway. However, for the many patients with Ras protein mutations or hyperactivation of the Ras pathway, there are still no clinically effective treatments targeting the Ras protein on the market. Therefore, the development of highly active small molecule inhibitors targeting the Ras protein, particularly the highly mutated K-Ras G12C protein, is considered to have great clinical significance.
[0007] K-Ras G12C mutaine is currently not a well-researched therapeutic target, with only a few compounds, such as Amgen's AMG510 and Mirati's MRTX849, undergoing clinical trials. In 2018, the covalent inhibitor ARS-1620, which targets the K-Ras G12C mutation, was reported in Cell (Cell, 2018, 172: 578-589). A class of spiro compounds possessing K-Ras G12C activity and antitumor activity in mice is reported in patent WO2018 / 143315, and its general formula A, representative compound B (Example 35 of the patent), and representative compound C (Example 65 of the patent) are shown as follows (see the patent for definitions of symbols in the formula).

[0031] It should be understood that both the above general description of the present invention and the following detailed description are illustrative and explanatory, and are intended to provide a further explanation of the claimed invention.
[0032] Compound synthesis The following describes in detail the preparation methods for the compounds of the general formulas (1) to (3) of the present invention, but these specific methods do not limit the present invention in any way.
[0033] The compounds of general formulas (1) to (3) described above can be synthesized using standard or well-known techniques, in combination with the methods described herein. The solvents, temperatures, and other reaction conditions described herein may also vary. Starting materials for the synthesis of the compounds can be obtained synthetically or commercially. The compounds described herein and other related compounds with different substituents can be synthesized using well-known techniques and starting materials, including March, Advanced Organic Chemistry, 4 th Ed., (Wiley 1992); Carey and Sundberg, Advanced Organic Chemistry, 4 th Ed., Vols. A and B (Plenum 2000, 2001), and Green and Wuts, PROTECTIVE GROUPS IN ORGANIC SYNTHESIS, 3 rd This includes the methods described in Ed., (Wiley 1999). General methods for preparing the compounds can be modified by using appropriate reagents and conditions for introducing different groups into the formulas provided herein.
[0034] In one embodiment, the compounds described herein are prepared according to methods well known in the art. However, the conditions relating to the method, such as reactants, solvents, bases, amounts of compounds used, reaction temperature, and reaction time, are not limited to those described below. Furthermore, the compounds of the present invention can be easily prepared by arbitrarily combining various synthesis methods described herein or known in the art, and such combinations can be easily determined by those skilled in the art to which the present invention belongs. In one embodiment, the present invention also provides a method for preparing compounds of general formulas (1) to (3) using the general reaction scheme 1 below.
[0035] General reaction scheme 1 [ka]
[0036] In an embodiment of the compound of general formula (1), the preparation can be carried out according to the general reaction scheme 1, where T represents H, F, Cl, or I, T 1 represents R 5 、R 5a 、or R 5b as defined above, T 2 represents R 3 、or R 3a as defined above, T 3 represents R 1 、or R 1a as defined above, T 4 represents R 2 、or R 2a as defined above, T 5 represents R 4 、or R 4a as defined above, R 1 、R 1a 、R 2 、R 2a 、R k 3 、R 3a 、R 4 、R 4a 、R 5 、R 5a 、and R 5b are defined as above, PG represents a protecting group, X represents boric acid, borate, or trifluoroborate.
[0037] In general, as shown in Reaction Scheme 1, compound A1 (synthesized according to WO2018 / 143315) is reacted with compound A2 under basic conditions to obtain compound A3, and compound A3 is reacted with T 1 H under basic conditions to obtain compound A4, and compound A4 is reacted with T 2 H under basic conditions to obtain compound A5. When T = I, compound A5 is subjected to a coupling reaction with T 3 X to obtain compound A6, and compound A6 is reacted with T 4Further coupling reaction of X yields compound A7. 4 Compound A7 can be directly obtained by further coupling reaction with X. Compound A8 can be obtained by removing the protecting group from compound A7, and then compound A8 can be reacted with compound A9 to obtain the target compound A10.
[0038] Further aspects of the compound In this specification, "pharmaceutically acceptable" refers to a substance such as a carrier or diluent that does not cause the compound to lose its biological activity or properties. It also refers to a substance that is relatively non-toxic and, for example, does not cause undesirable biological effects or adverse interactions with its components when administered to an individual.
[0039] A "pharmaceutically acceptable salt" means a form of a compound that does not cause significant irritation to the body for drug administration and does not eliminate the biological activity and properties of the compound. In certain contexts, a pharmaceutically acceptable salt can be obtained by reacting compounds of general formulas (1) to (3) with acids, such as inorganic acids like hydrochloric acid, hydrobromic acid, hydrofluoric acid, sulfuric acid, phosphoric acid, and nitric acid; organic acids like formic acid, acetic acid, propionic acid, oxalic acid, trifluoroacetic acid, malonic acid, succinic acid, fumaric acid, maleic acid, lactic acid, malic acid, tartaric acid, citric acid, picric acid, methanesulfonic acid, benzenesulfonic acid, and p-toluenesulfonic acid; and acidic amino acids like aspartic acid and glutamic acid.
[0040] References to pharmaceutically acceptable salts should be understood to include solvated or crystalline forms, particularly solvates or polymorphs. Solvates are selectively formed during crystallization with pharmaceutically acceptable solvents such as water and ethanol, in stoichiometric or nonstoichiometric amounts of solvent. Hydrates are formed when the solvent is water, and alkoxides are formed when the solvent is ethanol. Solvates of the compounds of general formulas (1) to (3) can be easily prepared or formed according to the methods described herein. For example, hydrates of the compounds of general formulas (1) to (3) can be easily prepared by recrystallization from a water / organic solvent mixture, the organic solvents used here including, but not limited to, tetrahydrofuran, acetone, ethanol, or methanol. Furthermore, the compounds described herein can exist in both non-solvated and solvated forms. In general, the solvated form is considered equivalent to the non-solvated form for the purposes of the compounds and methods provided herein.
[0041] In other specific examples, compounds of general formulas (1) to (3) may be prepared in different forms, such as amorphous materials, pulverized materials, and nanoparticles, but are not limited to these. Furthermore, compounds of general formula (1) may include crystalline forms as well as polymorphs. Polymorphs include different lattice arrangements of the same element in the compound. Polymorphs typically differ in X-ray diffraction patterns, infrared spectra, melting points, densities, hardness, crystalline forms, optical properties, electrical properties, stability, and solubility. Depending on various factors such as the recrystallization solvent, crystallization rate, and storage temperature, single crystals may be dominant.
[0042] In another embodiment, the compounds of general formulas (1) to (3) exist in the form of racemates, racemic mixtures, single enantiomers, diastereomer compounds, and single diastereomers, because they have axial chirality and / or chiral centers (chiral centers). Each of these axial chiralities independently gives rise to two optical isomers, and all possible optical isomers, diastereomer mixtures, and pure or partially pure compounds are included within the scope of the present invention. The present invention means that it includes all such isomeric forms of these compounds.

Fixed or temporary administration, or continuous or intermittent administration, may be caused by or related to the administration.
[0054] "Active ingredient" refers to the compounds of general formulas (1) to (3), and pharmaceutically acceptable inorganic or organic salts of the compounds of general formulas (1) to (3). The compounds of the present invention may contain one or more asymmetric centers (axial chirality) and therefore may exist in the form of racemates, racemic mixtures, single enantiomers, diastereomer compounds, and single diastereomers. The possible asymmetric centers depend on the properties of various substituents on the molecule.

The present invention means that it includes all such isomers of these compounds.
[0055] In this specification, terms such as “compound,” “composition,” “drug,” or “medicine or medicament” are used interchangeably and all refer to compounds or compositions that, when administered to an organism (human or animal), can induce a desired pharmacological and / or physiological response through local and / or systemic effects.
[0056] In this specification, "administered, given, or administered" means the direct administration of a compound or composition, or the administration of a prodrug, derivative, analog, etc., of an active compound.
[0057] While the numerical ranges and parameters defining the broad scope of this invention are approximations, the relevant numerical values shown in specific examples are presented herein as accurately as possible. However, any numerical value inherently includes a standard deviation that inevitably arises from certain test methods. Here, “approximately” generally means that the actual value is within a specific value or range of ±10%, 5%, 1%, or 0.5%. Alternatively, the term “approximately” indicates that the actual value is within the acceptable standard error of the mean, as those skilled in the art would consider. All ranges, quantities, values, and percentages used herein (e.g., describing quantities of material, durations of time, temperatures, operating conditions, quantitative ratios, etc.) shall be understood to be modified by the word “approximately” unless explicitly indicated in experimental examples or elsewhere. Thus, unless otherwise stated, all numerical parameters described herein and in the appended claims are approximations that may be modified as needed. At a minimum, these numerical parameters should be interpreted as numerical values obtained using the indicated significant figures or conventional rounding rules.
[0058] The scientific and technical terms used herein have the same meanings as those generally understood by those skilled in the art, unless otherwise defined herein.
