Description

Technical Field

[0001] This invention belongs to the field of pharmaceuticals, specifically relating to a substituted tricyclic inhibitor, its preparation method, and its application. Background Technology

[0002] Approximately one-quarter of all human cancers are caused by RAS mutations, resulting in nearly one million deaths annually. Within the RAS family, KRAS mutations account for 85% of all RAS mutations. KRAS mutations are found in nearly 90% of pancreatic cancers, 30-40% of colon cancers, and 15-20% of lung cancers (primarily non-small cell lung cancer).

[0003] KRAS protein is a small GTPase encoded by the KRAS gene and is an important regulatory protein for cell growth. Once activated, KRAS can activate multiple signaling pathways, promoting cell proliferation. The most common sites of KRAS protein gene mutation are codons 12, 13, and 61, with codon 12 mutations being the most frequent. The most prevalent KRAS G12 mutations are G12A, G12C, G12D, G12V, and G12S mutations, with G12C, G12D, and G12V mutations primarily occurring in NSCLC, CRC, and pancreatic cancer. To date, no drugs targeting multiple KRAS mutations have been approved for marketing.

[0004] Because the target protein of KRAS mutations is pathologically associated with a variety of diseases, especially lung cancer, pancreatic cancer, and colorectal cancer, there is a current need for novel KRAS mutation inhibitors for clinical treatment. Highly active KRAS mutation inhibitors can more effectively treat diseases such as cancers caused by KRAS mutations and have the potential to reduce off-target effects, thus meeting a more urgent clinical need.

The term "salt" as used herein refers to a salt formed from an inorganic or organic acid and a base in an acidic or basic form. Furthermore, when a compound of this invention contains a basic segment, it includes, but is not limited to, pyridine or imidazole; when it contains an acidic segment, it includes, but is not limited to, carboxylic acids; and any zwitterions ("internal salts") that may form are included within the scope of the term "salt." Pharmaceutically acceptable (i.e., non-toxic and physiologically acceptable) salts are preferred, although other salts are also useful, for example, for separation or purification steps in the preparation process. Compounds of this invention may form salts, for example, by reacting compound I with a certain amount, such as an equimolar amount, of an acid or base, precipitating it in a medium, or by freeze-drying it in an aqueous solution.

[0194] The compounds of this invention contain basic fragments, including but not limited to amines, pyridines, or imidazole rings, which may form salts with organic or inorganic acids. Typical acids that can form salts include acetates (such as acetic acid or trihaloacetic acids, such as trifluoroacetic acid), adipates, alginates, ascorbic acid salts, aspartate salts, benzoates, benzenesulfonates, hydrogen sulfates, borates, butyrates, citrates, camphor salts, camphor sulfonates, cyclopentanepropionate, diethylene glycol salts, dodecyl sulfates, ethanesulfonates, fumarates, glucono-2-phosphates, glycerol phosphates, hemisulfates, heptarates, hexanoates, hydrochlorides, hydrobromide, and hydroiodide.

[0196] The prodrugs and solvates of the compounds in this invention are also included within the scope of this invention. The term "prodrug" here refers to a compound that, in the course of treatment of a related disease, undergoes a chemical transformation through metabolism or a chemical process to produce the compounds, salts, or solvates of this invention.

[0197] The compounds, salts, or solvates of this invention may exist in tautomer forms (e.g., amides and imine ethers). All such tautomers are part of this invention.

[0198] All stereoisomers of compounds (e.g., those with asymmetric carbon atoms due to various substitutions), including their enantiomers and diastereomeric forms, are within the scope of this invention. The independent stereoisomers of the compounds in this invention may not coexist with other isomers (e.g., possessing special activity as a pure or substantially pure optical isomer), or may be mixtures, such as racemates, or mixtures formed with all other stereoisomers or a portion thereof. The chiral center of this invention has two configurations, S or R, as defined by the International Union of Theoretical and Applied Chemistry (IUPAC) in 1974. Racemic forms can be resolved by physical methods, such as stepwise crystallization, or by derivatization into diastereomers followed by crystallization, or by chiral column chromatography. Individual optical isomers can be obtained from racemates by suitable methods, including but not limited to conventional methods, such as recrystallization after salting with an optically active acid.

[0199] The compounds of this invention, obtained sequentially through preparation, separation, and purification, have a weight content equal to or greater than 90%, for example, equal to or greater than 95%, or equal to or greater than 99% (“very pure” compounds), as listed in the text description. Such “very pure” compounds of this invention are also included as part of this invention.

[0200] All configurational isomers of the compounds of this invention are included within the scope of this invention, whether in mixtures, pure or very pure forms. The definition of compounds in this invention includes both cis (Z) and trans (E) olefin isomers, as well as cis and trans isomers of carbocyclic and heterocyclic compounds.

[0201] Throughout the specification, groups and substituents can be selected to provide stable fragments and compounds.

[0202] Specific functional groups and chemical terminology definitions are detailed below. For the purposes of this invention, chemical elements are defined in the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75. th The definitions in Ed. are consistent. The definitions of specific functional groups are also described there. In addition, the basic principles of organic chemistry, as well as specific functional groups and reactivity, are explained in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausalito: 1999, the full contents of which are included in the references.

[0203] Some compounds of this invention may exist in specific geometric or stereoisomeric forms. This invention covers all compounds, including their cis and trans isomers, R and S enantiomers, diastereomers, (D) isomers, (L) isomers, racemic mixtures, and other mixtures. Additionally, the asymmetric carbon atom may represent a substituent, such as an alkyl group. All isomers and mixtures thereof are included in this invention.

[0204] According to the present invention, the ratio of isomers in a mixture of isomers can be varied. For example, a mixture containing only two isomers can have the following combinations: 50:50, 60:40, 70:30, 80:20, 90:10, 95:5, 96:4, 97:3, 98:2, 99:1, or 100:0. All ratios of isomers are within the scope of the present invention. Similar ratios readily understood by those skilled in the art, as well as ratios for mixtures of more complex isomers, are also within the scope of the present invention.

[0205] This invention also includes isotopically labeled compounds, equivalent to the original compounds disclosed herein. However, in practice, it is common for one or more atoms to be replaced by atoms with different atomic weights or mass numbers. Examples of isotopes that can be included in the compounds of this invention include hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine isotopes, respectively as follows: 2 H, 3 H, 13 C 11 C 14 C 15 N、 18 O、 17 O、 31 P, 32 P, 35 S, 18 F and 36 Cl. The compounds of this invention, or enantiomers, diastereomers, isomers, or pharmaceutically acceptable salts or solvates, wherein the isotopes or other isotopic atoms of the aforementioned compounds are all within the scope of this invention. Certain isotopically labeled compounds of this invention, for example... 3 H and 14 Radioactive isotopes of carbon are also included, and are useful in tissue distribution experiments of drugs and substrates. Tritium, i.e. 3 H and carbon-14, i.e. 14 C, their preparation and detection are relatively easy. They are the preferred isotopes. In addition, heavier isotopes such as deuterium are used for substitution. 2H, due to its excellent metabolic stability, offers advantages in certain therapies, such as increasing half-life or reducing dosage in vivo, and therefore may be preferred in some cases. Isotopically labeled compounds can be prepared using general methods, by replacing the non-isotopic reagent with an readily available isotopically labeled reagent, according to the scheme described in the examples.

[0206] To design the synthesis of a specific enantiomer of the compound of this invention, it can be prepared asymmetrically or derivatized with a chiral auxiliary. The resulting diastereomeric mixture is then separated, and the chiral auxiliary is removed to obtain the pure enantiomer. Alternatively, if the molecule contains a basic functional group, such as an amino acid, or an acidic functional group, such as a carboxyl group, it can be formed with a suitable optically active acid or base to form a diastereomer salt, which is then separated by conventional methods such as separation crystallization or chromatography to obtain the pure enantiomer.

[0207] As described herein, the compounds of this invention can be expanded with any number of substituents or functional groups. Generally, whether the term "substitution" appears before or after the term "optional," the general formula for substituents in the formulations of this invention refers to replacing a hydrogen radical with a substituent of a specified structure. When multiple positions in a particular structure are replaced by multiple specific substituents, each position of the substituent can be the same or different. The term "substitution" as used herein includes all permissible substitutions in organic compounds. In a broad sense, permissible substituents include acyclic, cyclic, branched-unbranched, carbocyclic, and heterocyclic, aromatic and non-aromatic organic compounds. In this invention, heteroatomic nitrogen may be supplemented with hydrogen substituents or any permissible organic compound described above to complete its valence state. Furthermore, this invention is not intended to limit permissible substituted organic compounds in any way. This invention considers the combination of substituents and variable groups to be beneficial in the treatment of diseases, such as infectious or proliferative diseases, in the form of stable compounds. The term "stable" here refers to a compound that is stable enough to maintain the integrity of its structure when tested over a sufficiently long period of time, preferably remaining effective over a sufficiently long period of time, and is used here for the purposes described above.

[0208] The compounds involved in this application and their pharmaceutically acceptable salt metabolites, as well as prodrugs that can be converted in vivo into structures of the compounds involved in this application and their pharmaceutically acceptable salts, are also included in the claims of this application.
