Preparation and application of pyrimidothiopyranone KRAS mutant protein inhibitors
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the entirety of Chinese patent application No. 202410133666.8, filed January 30, 2024. This application incorporates the entirety of the aforementioned Chinese patent application. Technical Field
[0003] The present invention belongs to the field of drug synthesis, and specifically relates to a novel KRAS G12D Inhibitors and their preparation methods and uses. Background Art
[0004] The present invention generally relates to novel compounds and methods for their preparation and use as KRAS inhibitors, for example, for the treatment of cancer.
[0005] RAS represents a group of closely related, monomeric, globular proteins of 189 amino acids (molecular weight 21 kDa) that are associated with the plasma membrane and bind to either GDP or GTP. RAS acts as a molecular switch. When RAS contains bound GDP, it is in a quiescent, or closed, state and "inactive." In response to exposure of cells to certain growth-promoting stimuli, RAS is induced to convert its bound GDP into GTP. Once bound to GTP, RAS is "switched on" and able to interact with and activate other proteins (their "downstream targets"). RAS proteins themselves have a very low intrinsic capacity and are unable to hydrolyze GTP back to GDP, thus remaining in their closed state. Turning off RAS requires external proteins called GTPase activating proteins (GAPs), which interact with RAS and greatly accelerate the conversion of GTP to GDP. Any mutation in RAS that affects its ability to interact with GAPs or convert GTP back to GDP results in prolonged activation of the protein, leading to prolonged cellular signaling that allows cells to continue growing and dividing. Because these signals drive cell growth and division, overactive RAS signaling may ultimately lead to cancer.
[0006] Structurally, the RAS protein contains a G domain, which is responsible for the enzymatic activity of RAS - guanine nucleotide binding and hydrolysis (GTPase reaction). It also contains a C-terminal extension called the CAAX box, which can be post-translationally modified and is responsible for targeting the protein to the membrane. The G domain is approximately 21-25 kDa in size and contains a phosphate-binding loop (P-loop). The P-loop is the pocket where nucleotides bind in the protein. This is a rigid part of the domain with conserved amino acid residues (glycine 12, threonine 26, and lysine 16) and is crucial for nucleotide binding and hydrolysis. The G domain also contains the so-called SwitchI (residues 30-40) and SwitchII (residues 60-76) regions, both of which are dynamic parts of the protein and are often referred to as "spring-loaded" mechanisms due to their ability to switch between resting and loaded states. The key interaction is a hydrogen bond formed by threonine 35 and glycine 60 with the γ-phosphate of GTP, which holds the Switch1 and Switch2 regions, respectively, in their active conformations. Upon GTP hydrolysis and release of the phosphates, the two relax to the inactive GDP conformation.
[0007] The best-known members of the RAS subfamily are HRAS, KRAS, and NRAS, primarily due to their association with various types of cancer. Mutations in any of the three major RAS isoforms (HRAS, NRAS, or KRAS) are the most common in human tumorigenesis. Approximately 30% of human tumors are found to harbor RAS gene mutations. Notably, KRAS mutations are detected in 25-30% of tumors. In contrast, the prevalence of oncogenic mutations in NRAS and HRAS family members is much lower (8% and 3%, respectively). The most common KRAS mutations are found at residues G12 and G13 of the P-loop and residue Q61. G12C is a frequent mutation in the KRAS gene (glycine 12 to cysteine). This mutation has been found in approximately 13% of cancers, approximately 43% of lung cancers, and approximately 100% of cases of MYH-associated polyposis (a familial colon cancer syndrome).
[0008] As a cutting-edge target, KRAS mutant protein has received widespread attention. Among them, AMG-510 developed by Amgen was approved for marketing by the FDA last year. In recent years, other companies have applied for a number of patents on KRAS inhibitors, such as WO2016164675, WO2016168540, WO2021141628, WO2022098625, WO2022087371, WO2020101736, WO2022109485, WO2022109487 and WO2020146613. Therefore, despite progress in this field, there is still a need in the art for improved compounds and methods for treating cancer, such as by inhibiting KRAS, HRAS or NRAS. The present invention meets this need and provides other related advantages.

[0060] Intermediate compounds of the compounds of the present invention and their polymorphs are also within the scope of the present invention.
[0061] Crystallization often produces solvates of the compounds of the present invention. The term "solvate" as used herein refers to an association of one or more molecules of the compound of the present invention with one or more solvent molecules.
[0062] The solvent may be water, in which case the solvate is a hydrate. Alternatively, it may be an organic solvent. Thus, the compounds of the present invention may exist as hydrates, including monohydrates, dihydrates, hemihydrates, trihydrates, tetrahydrates, and the like, as well as the corresponding solvated forms. While the compounds of the present invention may be true solvates, in other cases, the compounds of the present invention may simply retain water or a mixture of water and some other solvent. The compounds of the present invention may react in a solvent or precipitate or crystallize in a solvent. Solvates of the compounds of the present invention are also encompassed within the scope of the present invention.
[0063] The term "acceptable" with respect to a formulation, composition or ingredient, as used herein, means having no persistent detrimental effect on the general health of the subject being treated.
[0064] As used herein, the term "pharmaceutically acceptable" refers to a substance (such as a carrier or diluent) that does not affect the biological activity or properties of the compounds of the present invention and is relatively non-toxic, that is, the substance can be administered to a subject without causing an adverse biological response or interacting in an adverse manner with any components contained in the composition.
[0065] "Pharmaceutically acceptable carrier" includes, but is not limited to, adjuvants, carriers, excipients, auxiliary agents, deodorants, diluents, preservatives, dyes / colorants, flavor enhancers, surfactants and wetting agents, dispersants, suspending agents, stabilizers, isotonic agents, solvents, or emulsifiers that have been approved by relevant government administrative departments for use in humans and domesticated animals.
[0066] As used herein, the terms "subject," "patient," "subject," or "individual" refer to individuals suffering from a disease, disorder, or condition, including mammals and non-mammals. Examples of mammals include, but are not limited to, any member of the class Mammalia: humans, non-human primates (e.g., chimpanzees and other apes and monkeys); livestock, such as cattle, horses, sheep, goats, and pigs; domestic animals, such as rabbits, dogs, and cats; and laboratory animals, including rodents, such as rats, mice, and guinea pigs. Examples of non-human mammals include, but are not limited to, birds and fish. In one embodiment of the methods and compositions provided herein, the mammal is a human.
[0067] The term "treatment" as used herein refers to the treatment of a disease or condition in a mammal, especially a human, including
[0068] (i) preventing the development of a disease or condition in a mammal, particularly a mammal that has been previously exposed to the disease or condition but has not yet been diagnosed with the disease or condition;
[0069] (ii) inhibiting the disease or condition, i.e., controlling its development;
[0070] (iii) alleviate the disease or condition, i.e., cause the disease or condition to regress;
[0071] (iv) Alleviate symptoms caused by a disease or condition.
[0072] As used herein, the terms "disease" and "disorder" are used interchangeably or may have different meanings because certain diseases or disorders do not yet have a known causative agent (and therefore the cause of the disease is unknown) and therefore cannot be considered diseases but rather are considered to be undesirable conditions or syndromes with more or less specific symptoms that have been confirmed by clinical researchers.
[0073] As used herein, the terms "administer," "administer," "administer," and the like refer to methods that enable a compound or composition to be delivered to the desired site of biological action.
