Description

Heteroaryl derivative compounds and uses thereof

[0001] The present invention relates to heteroaryl derivative compounds and their pharmaceutical uses. Specifically, the present invention relates to heteroaryl derivatives having WEE1 and / or PKMYT1 inhibitory activity.

[0002] Protein kinases act as molecular switches in signal transduction pathways, requiring smooth cellular regulation of the transition between active and inactive states of target proteins. If this transition is abnormally regulated, it can lead to excessive activation or inactivation of intracellular signaling, leading to uncontrolled cell division and proliferation. In particular, abnormal activation of protein kinase genes, resulting from mutations, amplification, and / or overexpression, plays a crucial role in the development and progression of various tumors and in the pathogenesis of various diseases, including inflammatory diseases, neurodegenerative diseases, and autoimmune diseases.

[0003] The cell cycle is a tightly regulated process in which cells reproduce through DNA replication and division. During this process, cells pass through several checkpoints, consisting of the G1, S, G2, and M phases. These checkpoints detect and repair DNA damage and regulate division to ensure proper cell proliferation.

[0004] The WEE1 tyrosine kinase is a key regulator of the cell cycle. In particular, it plays a crucial role in the G2 phase checkpoint. This checkpoint maintains cellular stability by detecting DNA damage before cells enter the mitotic phase. WEE1 regulates this process by inhibiting the activity of CDK1 (or CDC2). Before cell division, CDK1 is inactive, and tyrosine is phosphorylated by WEE1, and threonine is phosphorylated by PKMYT1 (MYT1).

[0005] WEE1 is a negative regulator of the cell cycle and prevents the entry of the cyclin B-activated CDK1 complex into the nucleus. WEE1 expression and activity are both enhanced in S and G2 phases, and are then highly phosphorylated and then reduced in M ​​phase. When cells enter G2 phase and in the absence of DNA damage, polo-like protein kinase 1 (PLK1) phosphorylates WEE1 and degrades it through a ubiquitin ligase complex. PLK1 also activates the protein phosphatase cell division cycle 25 homolog (CDC25), which phosphorylates and dephosphorylates CDK1. Activated CDK1 can bind to cyclin B, promoting cell entry into the mitotic phase (Beck H et al., Molecular & Cellular Biology, 2012, 32 (20), 4226-4236).

[0006] WEE1 is overexpressed in various types of cancer, including liver cancer, breast cancer, malignant glioma, melanoma, adult brain tumors, and pediatric brain tumors. In some cancer cells, the G1 checkpoint is abnormal, or inhibition of WEE1 activity disrupts the G2 checkpoint, leading to cell division and eventual death, with unrepaired damaged DNA (Van Linden AA et al., Molecular Cancer Therapeutics, 2013, 12 (12), 2675-2684).

[0007] Meanwhile, PKMYT1 (MYT1; membrane-associated tyrosine and threonine specific cdc2 inhibitory kinase) belongs to the WEE1 kinase family and, together with WEE1, acts as a key regulator of the gateway to mitosis at the G2 checkpoint in the cell cycle. When DNA damage occurs in cancer cells, PKMYT1 plays a role in DNA damage repair (DDR) at the G2 checkpoint (Molecules, 2017, 22(12), 2045). Therefore, inhibition of PKMYT1 can suppress the activity of cancer cells by suppressing the G2 / M checkpoint function of cancer cells and inducing mitotic catastrophe (Journal of Hematology & Oncology, 2020, 13, 126).

[0008] Many patients with solid tumors do not respond to chemotherapy, which is attributed to cell cycle regulation and DDR in cancer cells. Furthermore, PKMYT1 is overexpressed in solid tumors such as non-small cell lung cancer (NSCLC), colorectal cancer (CRC), gastric cancer, hepatocellular carcinoma, glioblastoma, and breast cancer (Cell Proliferation, 2020, 53, e12741), and its overexpression in NSCLC patients is known to promote cancer progression and metastasis, leading to a poor prognosis (Eur Rev Med Pharmacol Sci., 2019, 23(10), 4210-4219).

[0009] Therefore, there is a growing need for novel compounds that may be useful in the treatment of diseases associated with WEE1 and / or PKMYT1 hyperactivation, amplification, or overexpression.

[0010] An object of the present invention is to provide a novel structural heteroaryl derivative, a stereoisomer thereof, or a pharmaceutically acceptable salt thereof.

[0011] Another object of the present invention is to provide a method for producing the heteroaryl derivative compound.

[0012] Another object of the present invention is to provide a pharmaceutical use of the heteroaryl derivative compound, and specifically, to provide a pharmaceutical composition for preventing or treating a disease related to WEE1 and / or PKMYT1 kinase activity, comprising the heteroaryl derivative compound as an active ingredient, a use for preventing or treating a disease related to WEE1 and / or PKMYT1 overactivation, amplification, or overexpression using the compound, or a method for preventing or treating a disease related to WEE1 and / or PKMYT1 overactivation, amplification, or overexpression, comprising a step of administering the compound.
