Abstract
Description
Background Technology
[0001] Cells are constantly challenged by endogenous and exogenous factors that can affect DNA integrity. To maintain genome stability and prevent the unwanted proliferation of damaged DNA, cells have established an organized signaling network that recognizes DNA damage and halts the cell cycle to properly repair DNA before resuming DNA replication or cell division. The DNA damage response and the cell cycle are closely linked through several cell cycle checkpoints, which are crucial control steps for maintaining genome integrity.
[0002] Cancer cells often possess defective G1 / S checkpoints, typically due to impaired p53 activity caused by mutations or deletions, or by inactivation of viral oncoproteins. Therefore, cancer cells heavily rely on other cell cycle checkpoints, including the G2 / M checkpoint, to avoid the accumulation of harmful DNA damage and mitotic catastrophe. Consequently, it is hypothesized that cancer cells are particularly vulnerable to inhibition by proteins that protect cells from mitosis. (Matheson, CJ et al.) Trends Pharmacol Sci 37, 872-881 (2016).
[0003] Wee1A kinase is a tyrosine kinase belonging to the Wee1 kinase family, which includes Wee1A kinase, Wee1B kinase, and Myt1 kinase. (Rorà, AGL et al.) J Hematol Oncol 13, 126 (2020). The main role of this kinase family is to regulate cell cycle progression and entry into mitosis (Wee1A kinase and Myt1 kinase) or meiosis (Wee1B kinase). The key complex regulating mitotic entry is the Cdk1 / cyclin B1 complex, also known as the mitosis-promoting factor. Wee1A kinase regulates mitotic entry by activating the inhibitory tyrosine 15 site (Y... 15 Phosphorylation of Cdk1 on the β-cell kinase limits the activity of the Cdk1 / cyclin B1 complex. Therefore, inhibiting Wee1A kinase can prevent the inhibitory Y-cell kinase from reaching the β-cell kinase. 15 Phosphorylation effectively promotes the activity of the Cdk1 / cyclin B1 complex. Premature activation of the Cdk1 / cyclin B1 complex can lead to premature mitosis in the presence of unrepaired DNA damage, ultimately resulting in mitotic catastrophe and cell death.
[0004] In addition to its established role in regulating mitotic entry at the G2 / M checkpoint, Wee1A kinase has also been proposed to play an important role at the S intracellular checkpoint by limiting Cdk2 activity. (Elbæk, CR et al.) Cell Reports38, 110261 (2022); Elbæk, CR et al. Mutat Res Fundam Mol Mech Mutagen 819-820, 111694 (2020). Cdk2 activity is regulated by Wee1A kinase in the same manner as Cdk1, via phosphorylation at tyrosine 15. Cdk2 is the major Cdk driving DNA replication, and inhibition of Wee1A kinase leads to excessive DNA replication, resulting in depletion of the nucleotide pool and degradation of the ribonucleotide reductase subunit RRM2 (Pfister, SX et al.). Cancer Cell 28, 557-568 (2015). Pfister et al. demonstrated that Wee1A kinase inhibition selectively kills H3K through dNTP starvation induced by RRM2 depletion. 36 ME3-deficient cancer cells. Histone methyltransferase SETD2 catalyzes H3K. 36 me3, thereby promoting RRM2 expression and dNTP synthesis. Inactivation of the SETD2 gene is common in clear cell renal cell carcinoma (ccRCC), and therefore may be sensitive to Wee1A kinase inhibition. A phase II trial is currently testing AZD1775 (NCT03284385) in SETD2-deficient solid tumors.
[0005] It has also been proposed that Wee1A kinase plays a role in controlling histone stoichiometry in late S phase by phosphorylating the core histone H2B at tyrosine 37. (Koh, S.-B) Cell Signal 94, 110310 (2022).
[0006] Cancers associated with high-risk human papillomavirus (HPV), such as head and neck squamous cell carcinoma (HNSCC), show increased sensitivity to Wee1A kinase inhibitors. (Diab, A. et al.) Proc National Acad Sci 117, 28287-28296 (2020).
[0007] Several Wee1A kinase inhibitors are currently being tested in clinical trials (Bukhari, AB et al.). Frontiers Oncol 12, 828684 (2022)) and has shown activity in many indications. The phase II study of the Wee1A kinase inhibitor AZD1775 (adavosertib) showed promising results in women with serous uterine carcinoma. Liu, JF et al. J Clin Oncol 39, 1531-1539 (2021). With RAS / TP 53Adatimb also showed efficacy compared to active surveillance of metastatic colorectal cancer with mutations. (Seligmann, JF et al.) J Clin Oncol 39, 3705-3715 (2021). In a phase 1b trial of 18 patients with platinum-resistant ovarian cancer, the combination of ZN-c3 (azenosertib) and paclitaxel resulted in an objective response rate (ORR) of 50% (…). J Clin Oncol 41, 2023 (Supplement 16; Abstract) 5513))。 Given the encouraging signs of Wee1A kinase inhibition in terms of clinical activity, there is an urgent need for novel Wee1A kinase inhibitors with improved potency and selectivity, as well as compounds that simultaneously inhibit Wee1A kinase and Myt1 kinase, to maximize the efficacy potential of this class of targets.

[0306] Use of compounds and pharmaceutically acceptable compositions
[0307] The compounds and compositions described herein are generally used to inhibit the protein kinase activity of one or more enzymes.
[0308] Examples of kinases inhibited by the compounds and compositions described herein and to which the methods described herein are effective include Wee1A kinase, or both Wee1A kinase and Myt1 kinase.
[0309] The activity of compounds used as inhibitors of Wee1A kinase or Myt1 kinase or mutants of any of the foregoing in this disclosure can be determined in vitro, in vivo, or in cell lines. In vitro assays include determinations of the phosphorylation activity and / or subsequent functional consequences or ATPase activity of inhibitors of activated Wee1A kinase, activated Myt1 kinase, or mutants of any of the foregoing. Alternative in vitro assays quantify the ability of the inhibitor to bind to Wee1A kinase.
[0310] In recent years, inhibition of the DNA damage response (DDR) pathway has attracted considerable interest in cancer treatment, and various DDR inhibitors have been developed. Among them, the most promising inhibitors target the Wee1 kinase family, which plays a crucial role in cell cycle regulation and DNA damage recognition and repair in both non-malignant and cancer cells.
[0311] Wee1 kinase family
[0312] The Wee1 kinase family consists of three serine / threonine kinases that share a conserved molecular structure and are encoded by the following genes: WEE1 (Alternatively, WEE1 G2 checkpoint kinase or Wee1A kinase) PKMYT1 (Alternatively, MYT1 kinase or membrane-associated tyrosine and threonine-specific cdc2 inhibitory kinase) and WEE2 (Alternatively, WEE2 oocyte meiosis inhibitory kinase or Wee1B kinase). In eukaryotic somatic cells, Wee1A and Myt1 kinases play key roles in cell cycle regulation, particularly in the transition to mitosis (Schmidt M, Rohe A, Platzer C, et al., Regulation of G2 / M transition by inhibition of Wee1 and PMyt1 kinases). Molecules(2017;22:2045). Their roles as regulators are crucial in normal cell cycle progression and in responding to DNA damage as part of the DNA damage response (DDR) pathway. Similarly, Wee1B kinase regulates cell cycle progression, and particularly meiosis (Solc P, Schultz RM, Motlik J. Prophase I arrest and progression to metaphase I in mouse oocytes: Comparison of resumption of meiosis and recovery from G2-arrest in somatic cells). Mol Hum Reprod . 2010;16:654-64).
[0313] Wee1B kinase
[0314] Wee1B kinase expression is germ cell specific and inhibits meiosis by phosphorylating Tyr15 of the CDK1-cyclin B complex (JY Zhu et al., J Med Chem. 2017; 60 (18), 7863-7875). Because of its well-characterized role in meiosis, previous and current drug development efforts have not focused on Wee1B kinase. Wee1B kinase plays a dual regulatory role in oocyte meiosis by preventing premature restart before ovulation and allowing exit from metaphase II at fertilization (Nakanishi M, Ando H, Watanabe N, et al., Identification and characterization of human Wee1B, a new member of the Wee1 family of Cdk-inhibitory kinases). Genes Cells . 2000;5(10):839-47). Although identified in several cancer types WEE2 Somatic mutations (1.9% of cases) and copy number (CN) alterations (CN loss in 22.5% of patients and CN increase in 22.5% of patients) (https: / / portal.gdc.cancer.gov) have been observed, but they have not yet been functionally linked to tumor development.
[0315] Myt1 kinase
[0316] Myt1 kinase is a multifunctional protein kinase located in the ER-Golgi complex, known to play a regulatory role in the cell cycle by inhibiting Cdk1 / cyclin B1-mediated mitosis (JY Zhu et al., J Med Chem. 2017; 60 (18), 7863-7875). As described above and throughout the paper, Myt1 kinase inhibits Cdk1 / cyclin B1 activity by phosphorylating Tyr15 and Thr14 of Cdk1 and isolating Cdk1 from the nucleus. Furthermore, Myt1 kinase is also involved in the reassembly of the ER-Golgi complex at the end of mitosis.
[0317] Wee1A kinase
[0318] Wee1A kinase regulates cell entry into mitosis during the G2 / M transition in S phase by phosphorylating Tyr15 of Cdk1, thereby inactivating the Cdk1 / cyclin B complex. Cells with disrupted G1 checkpoint activity (e.g., cancer cells) depend on Wee1A kinase to inhibit Cdk1, allowing G2 / M arrest for DNA repair. If Wee1A kinase activity is altered, disrupted cells may enter mitosis prematurely without the opportunity to fully replicate their DNA content or repair potential DNA damage that may occur during S phase. This characterization of the role of Wee1A kinase in the cell cycle makes it an attractive target for anticancer therapies, especially when used in combination with DNA damage agents (JY Zhu et al., J Med Chem. 2017; 60(18), 7863-7875).
