Description

Cyclic nitrogen compounds, their crystal forms, preparation methods and uses

[0001] This application claims priority to Chinese patent application 202410500685X, filed on April 24, 2024. The entire contents of the aforementioned Chinese patent application are incorporated herein by reference. Technical Field

[0002] This invention relates to cyclic nitrogen-containing compounds, their crystal forms, preparation methods, and uses. Background Technology

[0003] DNA damage is a crucial mechanism by which many chemotherapeutic drugs exert their antitumor effects. Double-strand breaks (DSBs) are one of the most common types of cell damage, caused directly by ionizing radiation or induced by ultraviolet radiation, reactive oxygen species (ROS), or other mutagens, such as common chemotherapeutic drugs like cisplatin, 5-FU, and etoposide. Unrepaired DNA damage leads to the arrest of cellular functions such as transcription and replication, inducing apoptosis or necrosis, and is subsequently cleared by immune cells. Tumor cells possess highly efficient damage repair or alternative repair pathways. Targeting key proteins in these DNA damage repair pathways to allow unrepaired DNA damage to accumulate and ultimately lead to cell death is a key strategy in cancer treatment.

[0004] DNA double-strand breaks are typically repaired through three pathways: non-homologous end joining (NHEJ), homologous recombination (HR), and alternative non-homologous recombination end joining (Alt-NHEJ, also known as microhomological end joining (MMEJ) or TMEJ). The HR repair pathway occurs only during the G2 and S phases and is error-free in the presence of sister chromatids. In mammals, over 90% of DSB damage is repaired via the NHEJ pathway. It is an error-prone repair pathway, resulting in deletion mutations <30 bp, insertion mutations <5 bp, or microhomological sequences <2 bp. Recent research indicates that when HR and / or NHEJ are deficient, cells highly rely on the third pathway, MMEJ, to repair broken DNA. Inhibition of MMEJ leads to apoptosis. MMEJ is also an error-prone repair pathway that relies on the DNA polymerase theta-mediated end joining (TMEJ) to repair DNA double-strand breaks.

[0005] DNA polymerase theta (Pol theta, or Polθ) is a key protein in the MMEJ repair pathway. It is a unique multifunctional polymerase composed of an N-terminal helicase domain, a central domain, and a C-terminal polymerase domain. Basic research has revealed that the polymerase domain is essential for DNA elongation at the DSB damage repair site, while the helicase and central domains play a crucial role in the recognition and binding of Polθ to substrates. Polθ can deactivate the interaction between DNA and the damage repair complex (e.g., competitive binding of single-stranded DNA to RAD51), inhibiting the HR repair pathway. Furthermore, the helicase domain of Polθ is involved in DNA replication arrest; its loss of function leads to increased replication pressure in tumor cells, resulting in apoptosis.

[0006] Polθ is not expressed or is expressed at low levels in normal tissues and cells, but it is highly expressed in various tumors, including lung cancer, breast cancer, HR-deficient ovarian cancer, gastric cancer, and colon cancer, and is associated with poor prognosis. In particular, over 70% of breast cancers show Polθ overexpression. These phenomena suggest that Polθ may play an important role in these cancers and is a potential tumor-specific target.

[0007] Studies knocking down or knocking out Polθ in tumor cells have revealed that Polθ deficiency can sensitize these cells to radiation, induce DSB production, enhance replication fork instability, and sensitize tumor cells to genotoxic agents, potentially enhancing the efficacy of radiotherapy and chemotherapy, making it a potential drug target. Research has also found a combined lethal effect between Polθ and HR deficiency; its small-molecule inhibitors can kill HR-deficient tumor cells in vitro and in vivo. Particularly in HR-deficient reversion mutation-resistant tumors resistant to PARP inhibitors (such as Olaparib), Polθ inhibitors can resensitize cells to PARP inhibitors, providing valuable therapeutic opportunities. Furthermore, given that Polθ is a key protein in the MMEJ pathway, its functional deficiency can also lead to increased genomic instability in cancer cells, increasing somatic mutations and facilitating the production of neoantigens. In addition, Polθ has been reported to participate in cGAS-STING-mediated immune activation; therefore, targeting Polθ also has the potential to enhance immunotherapy.

[0008] In summary, Polθ is a highly promising target for cancer treatment. Designing ATPase activity inhibitors targeting the Polθ protein to inhibit intracellular MMEJ, and using them alone or in combination with other chemotherapy, radiotherapy, antibody therapy, immunotherapy, etc., can kill tumor cells and has great potential in the treatment of tumors such as lung cancer, breast cancer, HR-deficient ovarian cancer, gastric cancer, colon cancer, prostate cancer, and pancreatic cancer.

[0330] Test Example 4

[0331] 1. Biochemical activity assay of Polθ inhibitors (ADP Glo assay)

[0332] The N-terminus of the Polθ protein contains a helicase domain with ATPase activity, capable of hydrolyzing ATP to ADP. The ATPase activity of the Polθ protein and the inhibitory effect of small molecule compounds on the protein can be analyzed using the ADP-Glo ​​assay kit (ADP-Glo™ Kinase Assay, Promega, V9102). The specific detection method is as follows:

[0333] 1) The helicase domain of the Polθ protein was purified using an insect system to obtain protein with a purity >90%. ssDNA (SEQ ID NO.1:5'-CCAGTGAATTGTTGCTCGGTACCTGCTAAC-3', Hangzhou Youkang Biotechnology Co., Ltd.) was ordered as the substrate for the Polθ protein; a reaction buffer containing 10 mM DTT (dithiothreitol), 20 mM MgCl2, Tris-HCl, and pH 7.5 was prepared.

[0334] 2) Prepare 2x ssDNA-Pol θ premix and perform the reaction in a 384-well plate. Set up a control group with only buffer and add the premix to the other groups. Add the compound using an automated pipette (Thermo, Multidrop 8), starting at a concentration of 10 μM and diluting by 1 / 3. Set up a total of 9 detection sites, with 2 replicates per group.

[0335] 3) Prepare a 2x ATP solution. Add an equal volume of 2x ATP solution to all wells and let stand at room temperature for 60 min.

[0336] 4) Following the Promega reagent instructions, add ADP-Glo ​​Detection Reagent to the reaction system and let it stand at room temperature for 60 minutes;

[0337] 5) Following the Promega reagent instructions, add Kinase Detection Reagent to the reaction system, let it stand at room temperature for 60 min, and use a microplate reader (Thermo, Varioskan LUX) to detect the chemiluminescence signal. Set the reading time interval for each well to 1000 ms.

[0338] Data analysis was performed on the measurement results: the CV% of the control group test results should be less than 10%, and the z' value should be greater than 0.5. Data meeting the above quality control requirements were used to calculate the inhibition rate of the compound (inhibition rate (%) = 100 * (control group average, experimental group) / (control group average - buffer group average). A nonlinear regression was used to fit the inhibition rate curve of the compound and the IC50 value was obtained.

[0339] 2. Cell viability assay for Pol θ inhibitors

[0340] The in vitro efficacy of the inhibitor was assessed using a cell viability assay, specifically the commonly used CTG assay, with CellTiter Glo reagent (Promega, G7573). The specific assay method is as follows:

[0341] 1) Culture DLD1 and DLD1- / - cells. One day before the assay, digest the cells with trypsin (0.025% Trypsin-EDTA, Hyclone), centrifuge at 1000 rpm for 3 min, and collect the cells. Count the cells using a cell counter (Shanghai Mengwei Biomedical Technology Co., Ltd., SmartCell600A.SC1006), and seed them into 96-well white culture plates at an appropriate seeding ratio.

[0342] 2) Drug treatment was performed 24 hours after cell seeding, which was recorded as Day 0. The compound was added using an automated pipette (Thermo, Multidrop 8). The plate was set as a 96-well plate with an initial concentration of 30 μM. The cells were diluted by 1 / 3 of the initial concentration, and a total of 9 detection points were set up, with 2 replicates per group. The cells were incubated at 37°C in a 5% CO2 incubator.

[0343] 3) Perform two solution changes on Day 3 and Day 7 respectively, and add the compound as in step 2);

[0344] 4) On Day 10, remove the cell culture plate and add an equal volume of CTG reagent (the CTG reagent needs to be brought back to temperature and premixed according to the reagent instructions). Gently mix for 10 minutes (speed 300) on a constant temperature mixer (Hangzhou Ausen Instrument Co., Ltd., MSC-100). Perform chemiluminescence detection using an ELISA reader (Thermo, Varioskan LUX).

[0345] 5) Perform data analysis on the measurement results: The CV% of the control group should be less than 20%, and the z' value should be greater than 0.5. For data meeting the above quality control results, calculate cell viability (inhibition rate (%) = 100 * (control group average - experimental group) / (control group average - culture medium control group average). Use GraphPad Prism8 to perform nonlinear regression fitting of the compound's inhibition rate curve and obtain the IC50 value.
