KINESIN KIF18A INHIBITORS AND USE THEREOF
[0001] CROSS REFERENCE TO THE RELATED APPLICATIONS
[0002] This application is based upon and claims priority to International Patent Application No. PCT / CN2024 / 130310, filed on Nov. 06, 2024, International Patent Application No. PCT / CN2025 / 074955, filed on Jan. 24, 2025, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD
[0003] The present invention belongs to the field of medicine and relates to a class of kinesin KIF18A inhibitors and their use for inhibiting cancer cell proliferation and treating cancers.
[0004] BACKGROUND OF THE DISCLOSURE
[0005] KIF18A is a member of the kinesin-8 family of motor proteins. Within cells, it uses the energy released from ATP hydrolysis to move towards the plus end of microtubules, utilizing these microtubules as tracks. KIF18A is localized at the plus end of microtubules, where it regulates the dynamic stability of microtubules and exhibits activity similar to that of a microtubule depolymerase. During mitosis, KIF18A is crucial for regulating spindle microtubule dynamics and chromosome oscillation, playing a key role in ensuring proper chromosome alignment, maintaining genomic stability, and facilitating the successful completion of mitosis.
[0006] The KIF18A gene belongs to the kinesin-8 subfamily of motor proteins and is a plus-end directed motor. KIF18A is thought to influence the dynamics of the plus end of centromeric microtubules, thereby controlling correct chromosome positioning and spindle tension. Depletion of KIF18A in HeLa cervical cancer cells results in longer spindles, increased chromosome oscillation during metaphase, and activation of the mitotic spindle assembly checkpoint. KIF18A appears to be a viable target for cancer therapy. It is overexpressed in various types of cancer, including but not limited to colon cancer, breast cancer, lung cancer, pancreatic cancer, prostate cancer, bladder cancer, head and neck cancer, cervical cancer, and ovarian cancer. Additionally, gene deletion or knockout, or inhibition of KIF18A affects the mitotic spindle apparatus in cancer cell lines. Specifically, inhibiting KIF18A in aneuploid or chromosomally unstable cell lines has been found to induce mitotic cell arrest, a known vulnerability that can lead to cell death through apoptosis, mitotic catastrophe, or death following mitotic slippage during interphase. Therefore, there is strong interest in finding inhibitors of KIF18A protein. Inhibiting KIF18A ATPase activity is thus a promising approach for developing new anti-cancer agents.

When the ring is a heterocycle, it can contain 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more heteroatoms, such as those selected from N, O, and S.
[0034] In this invention, one or more halogens can each be independently selected from fluorine, chlorine, bromine, and iodine.
[0035] The term "substituted" as used herein means that at least one hydrogen atom is replaced by a non-hydrogen group, provided that the replacement maintains normal valency and results in a stable compound. As used herein, the term "ring double bond" refers to a double bond formed between two adjacent ring atoms (e.g., C=C, C=N, or N=N) .
[0036] In the case where a nitrogen atom (e.g., amine) is present on the compounds of the invention, these nitrogen atoms can be converted into N-oxides by treatment with oxidizing agents (e.g., mCPBA and / or hydrogen peroxide) to obtain other compounds of the invention. Therefore, the nitrogen atoms shown and claimed are considered to cover both the shown nitrogen and their N-oxides to obtain derivatives of the invention.
[0037] When any variable appears more than once in any composition or formula of the compounds, its definition is independent each time it appears. Therefore, for example, if a group is substituted with 0-3 R, the group may be optionally substituted with up to three R groups, and each R is independently selected from the definition of R each time it appears. Moreover, combinations of substituents and / or variables are only allowed if such combinations result in stable compounds.

[0039] As used herein, the term "effective amount" refers to an amount of a drug or agent (i.e., a compound of the invention) that will elicit a biological or medical response of a tissue, system, animal, or human sought by a researcher or clinician. Additionally, the term "therapeutically effective amount" refers to an amount that results in an improvement in the treatment, cure, prevention, or mitigation of a disease, disorder, or side effect, or that reduces the rate of progression of a disease or disorder as compared to a corresponding subject that has not received the above amount. The effective amount may be one or more administrations, applications, or dosages and is not intended to be limited by specific formulation or administration routes. This term also includes amounts effective to enhance normal physiological function.
[0040] The term "treatment" as used herein encompasses its broadest meaning, including therapeutic and / or prophylactic treatment of a subject. Specifically, "treatment" includes any process that leads to the alleviation, suppression, elimination, and improvement and / or prevention of conditions, diseases, disorders, etc. For example, this includes alleviating, reducing, modulating, improving, eliminating, preventing, or improving symptoms. Therapeutic treatment includes alleviating, suppressing, or improving symptoms or conditions of a disease; preventing the onset of complications; improving underlying metabolic syndrome; inhibiting the onset of disease or symptoms, such as controlling the progression of a disease or condition; alleviating the disease or symptoms; reducing the disease or symptoms; mitigating complications caused by the disease or symptoms, or treating signs caused by the disease or symptoms. Prophylactic treatment includes preemptive measures to prevent, block, delay, or mitigate the onset or progression of a disease or condition, or to lessen the severity of the disease or condition.
[0041] Similarly, "therapeutic agents" also include drugs or reagents that provide therapeutic and / or prophylactic treatment to a subject.
[0042] The term "pharmaceutically acceptable" or "pharmaceutically acceptable" as used herein refers to those compounds, substances, compositions, and / or dosage forms that, in the reasonable medical judgment, are suitable for contact with human and animal tissues without undue toxicity, irritation, allergic reactions, or other problems or complications, and are commensurate with a reasonable benefit / risk ratio.
