Description

Technical Field

[0001] This invention belongs to the field of chemical and pharmaceutical technology, specifically relating to a class of 2,3-dihydropyrimidine[4,5-d]pyrimidine-4(1H)-one derivatives, their preparation methods, and uses. Background Technology

[0002] The cell cycle refers to the entire process of a cell from the completion of one division to the end of the next. The cell cycle includes four growth phases: the G1 phase, in which proteins and RNA are synthesized in large quantities after mitosis; the S phase, in which DNA is synthesized and replicated; the G2 phase, a preparatory phase before mitosis; and the M phase, in which the cell undergoes mitosis.

[0003] Before cells enter the M phase, DNA replication must be completed. Due to interference from various endogenous and exogenous factors, DNA often mutates or is damaged. These abnormal DNA molecules must be repaired before entering the next stage of the cell cycle; otherwise, mitotic catastrophe will occur, leading to cell death. Cell cycle checkpoints can pause the cell cycle, allowing cells to repair abnormal DNA before entering the M phase.

[0004] Cell cycle checkpoints are a complex regulatory system that ensures the quality of DNA replication and chromosome segregation during the cell cycle. Their core component is the CDKs / Cyclins complex, formed by the binding of cyclin-dependent kinases (CDKs) and cyclins. When abnormal events occur during the cell cycle, such as DNA damage or DNA replication inhibition, this regulatory system is activated, pausing the cell cycle. The cell cycle resumes once the cell repairs itself or the fault is resolved. There are multiple cell cycle checkpoints throughout the cell cycle. The G1 / S checkpoint at the end of G1 phase and the G2 / M checkpoint in G2 phase are two major checkpoints. The G1 / S checkpoint determines whether to enter the cell cycle by examining the state inside and outside the cell, thus determining whether the cell enters the S phase for DNA synthesis. The G2 / M checkpoint examines whether there is DNA damage or defects after DNA synthesis, thus determining whether the cell enters the M phase for mitosis. The core component of the G2 / M checkpoint is the CDK1 (human homolog also known as CDC2) / Cyclin B complex. CDC2 is maintained in an inactive state by phosphorylation before the cell enters mitosis, allowing the cell to detect and repair damaged DNA. Its phosphorylation state is regulated by protein kinases such as Wee1.

[0005] Wee1 protein kinase belongs to the nuclear serine and threonine protein kinase family and is a key inhibitory regulator of CDC2 activity. It can phosphorylate the Tyr15 site on CDC2, inhibit the activation of the CDC2 / Cyclin B complex, and arrest cells from entering the M phase until the damaged DNA is repaired. This ensures that DNA can enter mitosis without damage. However, the loss or inactivation of Wee1 can cause cells to enter mitosis prematurely, leading to mitotic failure and cell death.

[0006] Normal cells can complete DNA repair during the G1 phase using the G1 / S checkpoint. However, nearly 50% of cancer cells have mutations in the tumor suppressor gene p53, leading to G1 / S checkpoint dysfunction and a greater reliance on the G2 / M checkpoint for DNA repair. Cancer cells can evade DNA-damaging agents and radiation therapy through the G2 / M checkpoint. Weel kinase is highly expressed in many types of cancer cells. Inhibiting Weel activity can lead to G2 / M checkpoint dysfunction, causing tumor cells to skip the G2 phase of DNA repair, prematurely enter mitosis, and ultimately die, thus achieving the goal of cancer treatment.

[0007] In summary, inhibiting Wee1 activity can selectively induce the death of cancer cells with G1 / S checkpoint dysfunction, and targeted inhibition of Wee1 has great potential for cancer treatment.

[0008] AstraZeneca's Weel inhibitor AZD1775 is currently in clinical trials, with over 30 clinical trials under development showing promising therapeutic effects. Related patents include US20070254892, WO2007126122, EP2213673, WO2008133866, and WO2011034743. Abbott and Abbvie have also conducted research on Weel inhibitors, with related patents including US2012220572, WO2013126656, WO2013012681, WO2013059485, WO2013013031, and WO2013126656. Almac's patents related to Wee1 inhibitors include WO2014167347, WO2015019037, and WO2015092431.

[0050] Example 1: Preparation of compound CY1

[0051]

[0052] Step a: Preparation of intermediate 1-A

[0053] Under ice bath conditions, sodium hydride (60% dispersed in mineral oil, 5.6 g, 1.5 eq) was added in portions to a 100 mL solution of ethyl 2-methylmercapto-4-aminopyrimidine-5-carboxylate (20.0 g, 1 eq) in N,N-dimethylformamide. The mixture was stirred in an ice bath for 10 minutes. Then, o-chlorophenyl isocyanate (13.6 mL, 1.2 eq) was slowly added dropwise to the reaction mixture under ice bath conditions. The reaction solution was gradually brought back to room temperature and stirred for 4 hours at room temperature. After the reaction was completed by TLC, 100 mL of saturated sodium chloride solution was slowly added to the stirred reaction solution under ice bath conditions. After the mixture stopped producing bubbles, 500 mL of water was added, followed by 400 mL of ethyl acetate for extraction. The aqueous phase obtained by separation was extracted again with 400 mL of ethyl acetate. The aqueous phase was collected and the pH was adjusted to 4-5 with an appropriate amount of 5% citric acid.

[0133] Acetonitrile was added to a mixture of cis-1,2,6-trimethylpiperazine (2 g, 1 eq), potassium carbonate (6.5 g, 3 eq), and p-fluoronitrobenzene (2.6 g, 1.2 eq) at room temperature.

[0376] The inhibitory effect of the compounds in the examples on the growth of H1299 and H1975 cells was detected using the CCK-8 assay.

H1299 and H1975 cells were digested with trypsin, centrifuged at 1000 pm for 3 minutes, the supernatant was discarded, and the cells were resuspended in fresh medium and counted. Cells were seeded at a density of 2000 cells per well in 96-well cell culture plates and incubated overnight at 37°C in a 5% CO2 incubator. Stock solutions of the test substances (including the test compounds and AZD1775) were diluted with DMSO at ratios of 1:3 and 1:10 to eight concentrations (the last concentration being a DMSO negative control): 10 μM, 3.3 μM, 1 μM, 0.33 μM, 0.1 μM, 0.033 μM, 0.01 μM, and 0 μM (final DMSO concentration less than 1‰). Add 5 μL of each concentration to 120 μL of culture medium (25-fold dilution) and vortex to mix. Collect cells cultured overnight, remove the culture medium, add 195 μM fresh culture medium to each well, and then add 5 μL of the diluted culture medium containing the corresponding concentration of the test substance. Incubate the plate at 37°C in a 5% CO2 incubator for 3 days. Remove the stock solution and add 20 μL of CCK-8 to each well for continued incubation. After 2-4 hours, shake in the dark for 10 min and read the absorbance (OD) at 450 nm using a multi-function reader. Analyze the data using Graph Pad Prism 5.0 software; plot the inhibitory activity of the compound on cell proliferation against cell viability and compound concentration.
