Definitions
- the present invention belongs to the technical field of chemical medicine, and specifically relates to a quinazoline derivative RIPK2 inhibitor and a use thereof.
- RIPK2 (RIP2, RICK, CARDIAK, CARD3) is a dual-specificity serine/threonine and tyrosine kinase that regulates proinflammatory signals mediated by NOD1 and NOD2.
- the nucleotide-binding oligomerization domain (NOD) protein family is an important intracellular pattern recognition receptor, and NOD1 and NOD2 are two representative receptors of this protein family. Nod-like proteins in inflammation and disease (J. Pathol. 2008, 214, 136-148) and Nod-like proteins in immunity, inflammation and disease (Nat. Immunol.
- RIPK2-dependent signaling disorders have been shown to be associated with autoimmune diseases.
- Patients with NOD2 gene mutations are prone to Crohn's disease, Blau syndrome, early-onset sarcoidosis, dermatitis, arthritis, etc.
- NOD1 mutations are closely related to asthma and extraintestinal inflammatory diseases.
- RIPK2 is amplified in 65% of fatal prostate cancers, and approximately 34,000 American men die from this cancer each year.
- the amount of RIPK2 protein amplification increases as the cancer progresses, suggesting that the protein may play a very important role in the development of cancer. Therefore, clinical trials targeting RIPK2, either alone or in combination with existing or emerging treatments, are necessary to become personalized anti-metastatic treatments, thereby significantly improving clinical outcomes.

- FIG1 is a graph showing changes in IL-6 content in the MDP-induced mouse peritonitis model.
- the intermediate M2 (25.5 g, 100 mmol) from the previous step was dissolved in 100 mL POCl 3 , heated to 100 °C, and then 6-fluoro-5-aminobenzothiazole (20 g, 120 mmol) was added in batches. After the reaction was continued for 4 h, TLC monitoring showed that the reaction was complete. After cooling to room temperature, a large amount of solid precipitated. Filter, rinse the filter cake with 50 mL ether twice, and then slurry it with 100 mL water. After filtering, the filter cake was dried to obtain 32 g of relatively pure M3 intermediate, with a yield of 80%.
- the intermediate M4 (3.6 g, 7 mmol) from the previous step was dissolved in 20 mL of dichloromethane, and 20 mL of trifluoroacetic acid was added in batches.
- the reaction was completed after 0.5 hours at room temperature, and the reaction solution was concentrated.
- the concentrated solution was dispersed in water, and an appropriate amount of potassium hydroxide was added to adjust the pH until pH>9, and a large amount of solid precipitated.
- the filter cake was filtered and rinsed with ether to obtain a high-purity intermediate M5 (RP1) without further purification.
- Step f The reaction is further split into two different reaction conditions
- RIPK2 was incubated in buffer (20 mM MOPS, pH 8.5, 0.2 mM EDTA, 10 mM MnCl 2 ), and 0.33 mg/mL myelin basic protein, 10 mM magnesium acetate and [ ⁇ - 33 P-ATP], as well as different concentrations of compounds, and then Mg/ATP was added to the reaction to start the enzyme reaction process and incubated at room temperature for 120 minutes.
- RIPK1 was incubated in buffer (8 mM MOPS pH 7.0, 0.2 mM EDTA), and 0.33 mg/mL myelin basic protein, 10 mM magnesium acetate and [ ⁇ - 33 P-ATP], as well as different concentrations of compounds, and then Mg/ATP was added to the reaction to start the enzyme reaction process and incubated at room temperature for 120 minutes. Finally, the reaction was terminated by diluting the solution to 0.5% with phosphate buffer, and 10 ⁇ l of the reaction solution was titrated onto the P30 membrane, washed four times with 0.425% phosphate solution for 5 minutes each time, and then washed once with methanol. Finally, the P30 membrane was dried and scintillation counted.
- the scintillation count value reflects the degree of substrate phosphorylation, which can characterize the inhibition of kinase activity.
- the IC 50 value was fitted according to the inhibition rate of 9 concentrations, and the test was repeated. IC 50 value, A: 1-10nM; B: 10-100nM.
- the logarithmic phase THP-1 cells were centrifuged, collected, resuspended and counted, and then inoculated into a 96-well plate at 2.5 ⁇ 10 5 /mL and incubated overnight. After adding the test compound for 30 minutes, the cells were induced with 10 ⁇ g/mL MDP for 6 hours, and the cell supernatant was collected and the IL-1 ⁇ content was detected using an ELISA kit.
- mice were divided into a normal group, a model group, a positive control group and a test compound group.
- the normal group was not treated with any treatment. All compounds were administered by oral gavage at a dose of 3 mg/kg.
- MDP 100 ⁇ g/mouse was intraperitoneally injected. Four hours later, blood was collected from the eyeballs of the mice, and the IL-6 content in the serum was detected by Elisa.
- the experimental results are shown in Figure 1.
- the results showed that compared with the normal group, the IL-6 level (106.67pg/mL) was significantly increased after MDP modeling, indicating that the downstream inflammatory pathway was activated and the model was successfully induced.
- the IL-6 level in each drug-treated group declined to varying degrees compared with the model group, among which the compounds RP32 (38.81pg/mL) and RP74 (57.63pg/mL) declined more significantly than the positive control GSK2983559 (97.43pg/mL) at the same dosage, indicating that these two compounds more effectively inhibited the activity of RIPK2 kinase, blocked the activation of downstream inflammatory signals, and thus affected the synthesis and release of cytokine IL-6.
- mice The pharmacokinetic experiment was conducted on 2 male and 2 female BALB/c mice. The mice were fasted the night before administration and were orally administered at 5 mg/kg (p.o). 70-80 ⁇ L of blood was collected from the eye socket at 0 min, 5 min, 15 min, 30 min, 1 h, 2 h, 4 h, 8 h, 10 h and 24 h after administration. The collected blood was centrifuged at 3500 rpm for 15 min, and the serum was collected and frozen at -80 ° C. The collected samples were analyzed by LC/MS/MS and data were collected. The experimental results are shown in Table 10.
- the experimental results show that the compound of the present invention has excellent plasma exposure in mice.
