Background Art
[0003] RAS gene mutations are the most common activating mutations in human cancers and occur in approximately 30% of human tumors. The RAS gene family consists of three subtypes (KRAS, HRAS, and NRAS), and 85% of RAS-driven cancers are caused by mutations in the KRAS subtype. KRAS is a cancer gene of murine sarcoma virus and an important member of the RAS protein. KRAS is like a molecular switch and can control the cell proliferation pathway in a normal state. After mutation, the KRAS gene can transmit growth and proliferation signals to downstream pathways independently without depending on upstream growth factor receptor signals. As a result, cell proliferation is not controlled and tumors progress. At the same time, whether the KRAS gene has a mutation is also an important indicator for the prognosis of tumors.
[0004] KRAS mutations are common in solid tumors such as lung adenocarcinoma, pancreatic ductal carcinoma, and colorectal cancer. In KRAS mutant tumors, 80% of the oncogenic mutations occur at codon 12, and the most common mutations include p.G12D (41%), p.G12V (28%), and p.G12C (14%). In the United States, there are approximately 166,000 new patients with single KRAS mutations (G12D and G12V mutations account for the largest proportion), approximately 9,000 new patients with KRAS amplification, and approximately 4,000 new patients with multiple KRAS mutations. Currently, there is a lack of effective targeted therapeutic drugs in the overwhelming majority of patients.
[0005] So far, small molecules that directly target KRAS mutations mainly focus on the KRAS G12C region. Among them, Amgen's AMG510 and Mirati Therapeutics' MRTX849 have received manufacturing and sales approvals and have shown good therapeutic effects on patients with KRAS G12C mutant tumors. However, small molecules that target all KRAS mutations still have not entered the clinical research stage, and tumor patients with all KRAS mutations and KRAS amplification have not benefited from accurate medical treatment.

[0131] Related definitions Unless otherwise specified, the following terms and phrases used in this specification are intended to have the following meanings. A particular term or phrase should not be considered ambiguous or unclear even if not specifically defined, but should be understood in its ordinary meaning. When a trade name is listed in this specification, it is intended to refer to the corresponding product or its active ingredient.
[0132] As used herein, the term "pharmaceutically acceptable" refers to compounds, substances, compositions and / or dosage forms that are within the scope of sound medical judgment, are suitable for use in contact with the tissues of humans and animals without undue toxicity, irritation, allergic reaction, or other problems or complications, and exhibit a reasonable benefit / risk ratio.
[0133] The term "pharmaceutically acceptable salt" refers to salts of the compounds of the present invention prepared from compounds having the specific substituents found in the present invention and relatively non-toxic acids or bases. When the compounds of the present invention contain relatively acidic functional groups, base addition salts can be obtained by contacting such compounds with a sufficient amount of base in a pure solution or a suitable inert solvent. When the compounds of the present invention contain relatively basic functional groups, acid addition salts can be obtained by contacting such compounds with a sufficient amount of acid in a pure solution or a suitable inert solvent. Certain compounds of the present invention contain both basic and acidic functional groups and can thus be converted into any base addition salt or acid addition salt.
[0134] The pharmaceutically acceptable salts of the present invention can be synthesized from parent compounds containing acidic or basic groups by conventional chemical methods. Generally, such salts are prepared by reacting a compound in free acid or free base form with a stoichiometrically appropriate base or acid in water, an organic solvent, or a mixture of both.
[0135] Unless otherwise specified, the term "treatment" is intended to refer to all processes that may slow, interrupt, control, or stop the progression of a disease, but does not necessarily mean the elimination of all symptoms.
[0136] The compounds of the present invention may exist in the form of specific geometric or stereoisomers. In the present invention, all such compounds (including cis and trans isomers, (-) and (+) enantiomers, (R) and (S) enantiomers, diastereomers, (D) isomers, (L) isomers, their racemic mixtures, and other mixtures such as enantiomerically or diastereomerically enriched mixtures) are contemplated to be within the scope of the present invention. Additional asymmetric carbon atoms may be present in alkyl and other substituents. All of these isomers and their mixtures are included within the scope of the present invention.
[0137] The compounds of the present invention may contain atomic isotopes in unnatural proportions for one or more of the atoms that make up the compound. For example, the compound may be labeled with a radioactive isotope such as tritium ( 3 H), iodine-125 ( 125 I), or C-14 ( 14 C). For example, hydrogen may be replaced with deuterium to form a deuterated drug, and the bond formed by deuterium and carbon is stronger than the bond formed by normal hydrogen and carbon. Compared with non-deuterated drugs, deuterated drugs have advantages such as reduced toxicity and side effects, increased drug stability, enhanced efficacy, and extended biological half-life of the drug. All isotope composition conversions of the compounds of the present invention, whether radioactive or not, are within the scope of the present invention.
[0138] The terms "optional" or "optionally" mean that the event or circumstance described thereafter may occur but need not occur, and the description includes both the occurrence and non-occurrence of the described event or circumstance.
[0139] The term "substituted" means that any one or more hydrogen atoms on a particular atom are substituted with a substituent (which may include deuterium and variants of hydrogen), provided that the valence of the particular atom is standard and the substituted compound is stable. When the substituent is oxygen (i.e., =O), it means that two hydrogen atoms are substituted. The term "optionally substituted" means "may or may not be substituted", and unless otherwise specified, the type and number of substituents may be arbitrary based on what is chemically achievable.
[0140] In the composition or structure of a compound, when any variable (e.g., R) appears more than once, the definition of the variable in each instance is independent. Thus, for example, if a group is substituted with 0 to 2 Rs, the group may optionally be substituted with up to 2 Rs, and in each instance, R has independent choices. Further, combinations of substituents and / or their variants are permitted only if the compound is stable by such combinations.
[0141] When the number of linking groups is 0 (e.g., -(CRR)0-), it is indicated that the linking group is a single bond.
[0142] When one of the variables is selected from a single bond, it is indicated that the two groups thereby linked are directly linked. For example, when L in A-L-Z represents a single bond, it is indicated that the structure is actually A-Z.
[0143] When the described linking group does not indicate a linking direction, the linking direction is arbitrary. For example,

[0144] Unless otherwise specified, when a group has one or more linkable sites, any one or more sites of that group can be linked to other groups by chemical bonds. When the chemical bond is linked non-positionally and the linking site has an H atom, the number of H atoms at the linking site can decrease according to the corresponding valence of the group in accordance with the number of linking chemical bonds. The chemical bond linking the site to another group is a solid straight line
