Definitions
- the present invention relates to a class of compounds with inhibitory activity of WEE1 kinase and their use in treating diseases mediated by WEE1.
- WEE1 tyrosine kinase is a checkpoint in the G2 phase of the cell cycle.
- the cell cycle is tightly regulated. When the cell's DNA is not damaged, the G1 phase, S phase, and G 2 phase checkpoints promote cells to enter the division phase and ensure the smooth completion of the cell cycle. (Clinical Cancer Research, 2011, 17(13): 4200-4207.)
- the cell cycle is regulated by cyclin-dependent kinases (CDKs).
- CDKs cyclin-dependent kinases
- the CDKs family has 14 serine/threonine protein kinases. CDK activity is regulated by phosphorylation and binding to different cycle proteins.
- CDK1 also known as CDC2
- WEE1 phosphorylation of CDK1
- MYT1 myelin transcription factor
- WEE1 is a negative regulator of the cell cycle.
- WEE1 By preventing cyclin B and activated CDK1 complexes from entering the nucleus, WEE1 negatively regulates cells from the G2 phase to the division phase.
- the expression and activity of WEE1 are increased in S phase and G2 phase, and decreased in the highly phosphorylated M phase.
- polo-like protein kinase 1 phosphorylates WEE1 and degrades WEE1 through the ubiquitin ligase complex.
- PLK1 also phosphorylates and activates the protein phosphatase cell division cycle 25 analog (CDC25), which activates CDK1 through dephosphorylation.
- Active CDK1 can bind to cyclin B and promote cells to enter the division phase (Molecular & Cellular Biology, 2012, 32(20): 4226.).
- the G1, S and G2 phase checks delay the cell's entry into the division phase, buying time for the cell to repair the damaged DNA before it enters division, thereby ensuring the integrity of the genome.
- P53 a key regulator of the G1 phase checkpoint, is mutated in many malignant tumor cells. (Proceedings of the National Academy of Sciences of the United States of America, 2007, 104(10): 3753-3758.) Tumor cells with defective P53 function cannot arrest the cell cycle in the G1 phase when their DNA is damaged. Therefore, it relies more on the G2 phase checkpoint.
- the G2 phase checkpoint In response to DNA damage, the G2 phase checkpoint inhibits the phosphorylation of CDK1 through two parallel and interconnected pathways, thereby delaying cells from entering the division phase.
- ataxia telangiectasia variant (ATM) protein kinase or ataxia telangiectasia related (ATR) protein kinase is activated (Oncotarget, 2016, 7(31): 49902-49916.) .
- ATM is activated by ionizing radiation, radioactive agents, and agents that cause double-stranded DNA breaks.
- ATM phosphorylates and activates checkpoint kinase 2 (CHK2), which phosphorylates Ser216 of cell division cycle 25C phosphatase (CDC25C).
- CHK2 checkpoint kinase 2
- CDC25C cell division cycle 25C phosphatase
- Inhibiting the activity of CDC25C results in the inhibition of the phosphorylation of the CDK1/CDK2-binding cyclin B complex, leaving CDK1 in an inactive form and inhibiting cells from entering the division phase (Molecular Cancer, 2014, 13(1): 72.).
- ATR is activated by a wide range of genotoxic stimuli that lead to single-stranded DNA breaks.
- ATR is the primary kinase responsible for phosphorylating and activating CHK1.
- CHK1 can be activated by both ATM and ATR.
- CHK1 simultaneously phosphorylates WEE1 and CDC25C, activating WEE1 kinase activity and inhibiting the phosphatase activity of CDC25C.
- WEE1 phosphorylates CDK1-binding cyclin B, causing cell cycle arrest in the G2 phase, providing time for DNA repair (Drug News & Perspectives, 2010, 23(7): 425.).
- WEE1 is overexpressed in many malignant tumors, such as liver cancer, breast cancer, malignant glioma, melanoma, and brain tumors in adults and children. Some tumor cells have abnormal G1 checkpoints. If WEE1 activity is inhibited, G2 checkpoint failure will occur. At this time, cells with unrepaired damaged DNA will continue to divide and eventually divide and die. (Molecular Cancer Therapeutics, 2013, 12(12): 2675-2684.) Whether through pyrimidine derivatives (PD0166285) or small interfering RNA knockdown, inhibiting the activity of WEE1 will cause ovarian cancer, colon cancer, cervical cancer, and osteosarcoma.
- malignant tumors such as liver cancer, breast cancer, malignant glioma, melanoma, and brain tumors in adults and children. Some tumor cells have abnormal G1 checkpoints. If WEE1 activity is inhibited, G2 checkpoint failure will occur. At this time, cells with unrepaired damaged DNA will continue to divide and eventually divide and die.
