Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medicine, and particularly relates to a pyrrolopyrimidine compound and a preparation method and application thereof. BACKGROUND

[0002] Non-small cell lung cancer (NSCLC) accounts for about 80-85% of total lung cancer, mainly including squamous cell carcinoma, adenocarcinoma and large cell carcinoma. Compared with small cell lung cancer, NSCLC cell proliferation and diffusion speed is slower, but it is still one of the main causes of cancer-related deaths.

[0003] With the development of molecular medicine, targeted therapy has become an important treatment strategy for advanced NSCLC. Among them, epidermal growth factor receptor (EGFR) mutation is one of the most common driver gene mutations in NSCLC, accounting for about 40-50% in Asian non-smoking lung adenocarcinoma patients. EGFR mutation can abnormally activate the downstream signaling pathway, promote tumor cell growth and survival.

[0004] Targeted drugs for EGFR mutation, such as first and second generation EGFR tyrosine kinase inhibitors (TKIs) - Gefitinib and Erlotinib have been widely used in clinical. However, patients usually develop drug resistance due to T790M mutation after 9-12 months of treatment, leading to disease progression.

[0005] Osimertinib (AZD9291) is the third generation irreversible EGFR-TKI, which can selectively inhibit EGFR T790M mutations, and also has good inhibitory effect on common activating mutations of EGFR (such as L858R and exon 19 deletion mutation). Osimertinib inhibits mutant EGFR by covalently binding to ATP binding site, while it has weak effect on wild-type EGFR, thereby reducing common adverse reactions such as skin rash and diarrhea. Based on the good efficacy of AURA study, Osimertinib has become the first-line treatment for patients with EGFR mutant NSCLC. However, some patients may still develop disease progression after receiving Osimertinib treatment due to new drug resistance mechanisms such as EGFR C797S mutations, MET or HER2 gene amplification.

[0006] To address the treatment challenges after osimertinib resistance, new generation EGFR-TKIs are being developed. For example, BU-945 is a new, highly selective EGFR inhibitor designed to overcome C797S mutation resistance. Studies have shown that BU-945 has a strong inhibitory effect on C797S mutant EGFR and has shown good safety and tolerability in preclinical studies. In addition, BU-945 has less effect on wild-type EGFR, thereby reducing related adverse reactions, making it a promising treatment option for drug-resistant patients.

[0007] Although EGFR-TKIs have significantly prolonged the survival of patients with EGFR-mutant NSCLC, drug resistance remains a challenge that cannot be ignored. Osimertinib successfully overcomes T790M mutation resistance, and the development of new inhibitors such as BU-945 provides new treatment hope for C797S mutant patients. In the future, through combination therapy or new drug development, it is expected to further optimize the treatment strategy for EGFR-mutant NSCLC and improve the treatment effect of patients.

[0186] Preparation of 4-((4-phenoxyphenyl)amino)-N-(2-(thiophen-2-yl)ethyl)-7H- pyrrolo[2,3-d]pyrimidine-7-carboxamide:

[0187] Step one: Preparation of phenyl 4-chloro-7H-pyrrolo[2,3-d]pyrimidine-7-carboxylate (intermediate 2)

[0188] Put the prepared ice bath device on the room temperature stirrer, and add NaCl in ice water to reduce the temperature to 0°C. Weigh 4 g (25.56 mmol) of 4-chloro-7H-pyrrolopyrimidine (raw material 1) into a round-bottom flask containing 60 mL of tetrahydrofuran, then add 3 mL of triethylamine, and dropwise add 1.6 equivalents of phenyl chloroformate (6.4 g, 40.896 mmol). Stir in the ice bath for four hours, and monitor the reaction by TLC. After the reaction is complete, add petroleum ether solvent to ultrasonic, filter, wash the filter cake with the filtrate, and air dry to obtain a white solid, which is intermediate 2, with a yield of 90%.

[0189] Step two: Preparation of phenyl 4-((4-phenoxyphenyl)amino)-7H-pyrrolo[2,3-d]pyrimidine-7-carboxylate (intermediate 3a)

[0190] Dissolve intermediate 2 (2.1 g, 13.5 mmol) in 80 mL of super-dry 1,4-dioxane under nitrogen protection, and add 20 mL of saturated potassium carbonate aqueous solution to make the reaction system weakly alkaline. Add 0.19 g of 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene and 1,1'-binaphthalene-2,2'-bis(diphenylphosphine) (0.38 mmol), heat the reaction mixture to 95°C, and then add 4-phenoxyaniline after reaction. Stir for 8 hours, and monitor the reaction by TLC. After the reaction is complete, remove most of the organic solvent by rotary evaporation under reduced pressure, filter with water, dry the filter cake, and purify by column chromatography to obtain a white solid, which is intermediate 3a, with a yield of 65%.

[0191] Step three: Intermediate 3a (1.0 g, 2.5 mmol) was dissolved in dry acetonitrile (20 mL) to form a homogeneous solution. To the above solution, thienyl ethylamine (0.3 g, 2.75 mmol) was added under stirring condition. The reaction was continued under stirring condition. Triethylamine (0.5 mL) was added slowly to the reaction mixture for neutralization of the byproduct formed and to improve the efficiency of the reaction. The reaction mixture was stirred at 60 °C. The progress of the reaction was monitored by thin layer chromatography and completion of the reaction was confirmed. After completion of the reaction, the reaction solution was cooled to room temperature and the solution was washed with water to remove excess base and water soluble byproducts. The organic layer was extracted with ethyl acetate and the organic layers were combined and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure to obtain the crude product. The crude product was purified by silica gel column chromatography using ethyl acetate / pet ether mixture as eluent and the product was collected.

[0304] The in vitro anti-tumor activity of the pyrrolopyrimidine compounds prepared in Examples 1-42 was determined:

[0305] The selected cancer cells were lung cancer cells H1975, lung cancer cells A549 and lung cancer cells PC-9, and the control was Osimertinib.

[0306] (1) After the cells were recovered and subcultured for 3 times, they were digested from the bottom of the culture bottle with trypsin solution (0.25%). The cell digestion solution was aspirated into a centrifuge tube, and then culture medium was added to terminate digestion. After centrifuging the centrifuge tube at 1000 r / min for 3 min, the supernatant was discarded, 3 mL of culture medium was added, the cells were mixed by blowing, 10 μL of cell suspension was aspirated and added to a cell counting plate for counting, and the cell concentration was adjusted to 10 4 cells / well. Except for the blank wells at the top, bottom and left side of the 96-well plate, 180 μL of cell suspension was added to the rest of the wells. The 96-well plate was placed in an incubator for 24 h.

[0307] (2) The test sample was dissolved in 20 μL of dimethyl sulfoxide, then 980 μL of culture medium was added to dissolve the sample to 1 mg / mL of the example liquid, and then the sample was diluted to 1, 0.333, 0.111, 0.037, 0.012 μg / mL in an EP tube. Each concentration of the example was added to 3 wells, 20 μL per well, and the cell growth in the surrounding two rows and two columns was greatly affected by the environment, so only blank cell wells were used. The 96-well plate was placed in an incubator for 72 h.

[0308] (3) Discard the drug-containing culture solution in the 96-well plate, rinse the cells twice with phosphate buffer solution (PBS), add 100 μL of MTT (tetrazolium, 0.5 mg / mL) to each well, and place in the incubator for 4 h. Discard the MTT solution, and add 100 μL of dimethyl sulfoxide. Shake on a magnetic shaker to dissolve the MTT reaction product formazan in the surviving cells, and place in an enzyme marker instrument to measure the results at 492 nm.

[0309] The results of the activity of the pyrrolopyrimidine compounds prepared in Examples 1-42 in inhibiting lung cancer cells H1975, lung cancer cells A549, and lung cancer cells PC-9 are shown in Table 2, in which NA indicates that the IC 50 >100.00 μM.

[0311]

[0312]

[0313] As can be seen from Table 2, the pyrrolopyrimidine compound prepared in Example 42 has the best inhibitory activity on cancer cells.

[0314] The pyrrolopyrimidine compound prepared in Example 42 was subjected to molecular docking with EGFR to study the structure-activity relationship thereof with EGFR, and the results are shown in Figure 1 , in which A is the molecular docking result, B is the molecular surface electrostatic potential map, and C is the molecular docking score and RMSD data.

[0315] As can be seen from Figure 1 , the pyrrolopyrimidine compound is stably combined in the active pocket of EGFR and forms important interactions with key residues. The indole nitrogen atom of the ligand forms a hydrogen bond with Met793 in the hinge region This action helps to stabilize the molecule in the binding pocket. The nitrogen heterocyclic structure located in the affinity pocket enhances the affinity with the protein. In addition, the aromatic ring structure penetrates into the hydrophobic pocket and forms hydrophobic interactions with residues such as Leu718 and Val726, thereby further stabilizing the binding mode. As shown in Figure 1 , the docking calculation result shows that the best binding mode (Mode 1) of the molecule has the lowest binding free energy (-10.96 kcal / mol).

[0316] The effect of the pyrrolopyrimidine compound prepared in Experimental Example 42 on the morphology of cancer cells was observed by AO staining experiment:

[0317] Acridine Orange (AO) fluorescence staining is a technique for observing cell morphology and evaluating survival status. This method takes advantage of the binding properties of AO to nucleic acids, which exhibit different fluorescent colors in cells of different states, thereby distinguishing between living cells, apoptotic cells, and necrotic cells.

[0318] The specific operation steps are as follows:

[0319] (1) The cell density of H1975 cell suspension was 4 x 10 4 cells / mL, and 1 mL was added to each well of a 24-well plate, which was then incubated in a cell incubator for 24 h.

[0320] (2) The original culture solution was aspirated, and PBS was washed twice. 1 mg of the pyrrolopyrimidine compound prepared in Example 42 was dissolved in 20 μL of DMSO, and then serum-free medium was added to prepare a solution with a concentration of 1 μM and 2 μM. The drug solution was added at 1 mL per well, gently shaken to mix, and then incubated in a cell incubator for 12 h. A blank control was prepared without adding the drug solution, and AZD-9291 at a concentration of 1 μM was used as a positive control.

[0321] (3) The culture medium was aspirated and washed twice with 1 mL of PBS. After being washed once with 500 μL of 1 x buffer, 200 μL of AO staining solution (acridine orange: 1 x buffer = 1:20) was added, and the plate was incubated in a cell incubator for 15 min.

[0322] (4) The buffer was aspirated, and each well was washed 3 times with PBS. 500 μL of PBS was added, and the plate was observed under a microscope. The filter was rotated to 4 / 5, the laser was adjusted to blue light, and the plate was photographed and saved.

[0323] The staining results are shown in Figure 2 .

[0324] Figure 2 As shown, under a fluorescence microscope, the H1975 cells in the control group had an intact morphology, the nucleus and cytoplasm exhibited uniform green fluorescence, the cells were closely distributed, and no obvious apoptotic characteristics were observed. After being treated with the pyrrolopyrimidine compound (1 μmol / L) for 24 h, some of the cells showed morphological changes, the nucleus and cytoplasm were slightly reduced in size, and a small number of cells exhibited yellow fluorescence, indicating the occurrence of early apoptosis. As the concentration of the pyrrolopyrimidine compound increased to 2 μmol / L, more cells were observed to have reduced volume, fuzzy edges, and orange-red fluorescent cells, indicating an increase in late apoptosis. In addition, the space between the cells became larger, indicating that some of the cells had died. The changes in the pyrrolopyrimidine compound (2 μmol / L) group were similar to those in the AZD-9291 (1 μmol / L) group, and showed a certain degree of apoptotic characteristics. Overall, the pyrrolopyrimidine compound prepared in Example 42 can dose-dependently induce H1975 cell apoptosis, and the effect is more obvious at a high concentration.

[0325] The effect of the pyrrolopyrimidine compound prepared in Experimental Example 42 on apoptosis of cancer cells was observed by FITC / PI double staining method combined with flow cytometry:

[0326] The apoptosis was detected by FITC / PI (fluorescein isothiocyanate / propidium iodide) double staining method. FITC-labeled Annexin V can specifically recognize and bind to the phosphatidylserine (PS) on the early apoptotic cell membrane. And PI can only enter the late apoptotic or necrotic cells with damaged cell membrane, making the nucleus stained red fluorescence. By this method, normal cells, early apoptotic cells and late apoptotic / necrotic cells can be distinguished.

[0327] The specific operation steps are as follows:

[0328] (1) After the H1975 cells were digested and centrifuged by the subculture method, the number of cells was counted, and 2.0×10 5 cells per well were inoculated into a 6-well plate. Then, the cells were incubated in a 37℃, 5% CO2 incubator for 24 h to adhere to the wall.

[0329] (2) After 24 h, 3 mL of serum-free medium was added to each well, and 300 μL of the prepared pyrrolopyrimidine compound (1 μM, 4 μM) and positive drug (AZD-9291, 1 μM) of Experimental Example 42 were added, respectively. The blank control was not added with drug solution. Then, the plate was placed in a 37℃, 5% CO2 incubator for 24 h.

[0330] (3) The 6-well plate was placed in a clean bench, and the original culture medium was aspirated and washed twice with PBS. 1 mL of trypsin without EDTA was added to each well, and after the cells were completely detached, 1 mL of culture medium was added to terminate the digestion, and then the cells were washed once and transferred to a 5 mL centrifuge tube and centrifuged. The supernatant was discarded, 1 mL of PBS was added to the centrifuge tube, and the cells were gently blown to make them uniform. This step was repeated twice.

[0331] (4) The centrifuge tube was wrapped with tin paper to avoid light. 500 μL of buffer was added to each centrifuge tube, and the cells were gently blown for 8-10 times. 5 μL of Aximnex V and 5 μL of PI dye were added to the blank control group, and the prepared pyrrolopyrimidine compound of Experimental Example 42 and the positive group were repeated with the blank control group. The mixture was incubated in the dark for 30 min.

[0332] (5) The cell staining mixture was counted by flow cytometry at 1.0×10 4 cells, and the data was recorded.

[0333] The detection results are shown in Figure 3 .

[0334] Figure 3 The total apoptosis rate of the blank control group was only 1.38%, while the apoptosis rates of the 1 μM and 4 μM treatment groups were increased to 4.18% and 8.17%, respectively. The effect of the 4 μM treatment group was comparable to that of the positive control drug AZD9291 (1 μM), and the proportion of late apoptosis was increased by 4%. These results show that the pyrrolopyrimidine compound prepared in Example 42 can significantly induce H1975 cell apoptosis and mainly promote the cells to enter the late apoptosis stage, exhibiting good antitumor activity.

[0335] The effect of the pyrrolopyrimidine compound prepared in Example 42 on the cell cycle of cancer cells was detected by flow cytometry:

[0336] The specific operation steps are as follows:

[0337] (1) After the H1975 cells were digested and centrifuged by the subculture method, the number of cells was counted, and 2.0 x 10 5 cells per well were inoculated into a 6-well plate. Then, the cells were incubated in a 37°C, 5% CO2 incubator for 24 h to allow the cells to adhere.

[0338] (2) After 24 h, 3 mL of serum-free medium was added to each well, and 300 μL of the pyrrolopyrimidine compound prepared in Example 42 (1 μM, 4 μM) and the positive drug (AZD-9291, 1 μM) were added, respectively. The blank control was not added with the drug. Then, the cells were incubated in a 37°C, 5% CO2 incubator for 24 h.

[0339] (3) The H1975 cells were digested with trypsin without EDTA, centrifuged in a 5 mL centrifuge tube, washed with 1 mL of PBS twice (centrifuged), and 500 μL of PBS was added to blow the cells evenly. 500 μL of 70% cold ethanol (ethanol + PBS) was slowly added, and the cells were fixed in a 4°C refrigerator.

[0340] (4) After 2 h, the cells were taken out from the refrigerator and centrifuged, washed with PBS twice. 500 μL of PBS was added and blown evenly. 200 μL of dye (Rnase A: PI = 1:9) was added to each tube, and the mixture was placed in the dark for 30 min.

[0341] (5) The cell dye mixture was counted by flow cytometry at 1.0 x 10 4 cells, and the data was recorded.

[0342] The detection results are shown in Figure 4 .

[0343] From Figure 4As can be seen, after treatment with the pyrrolopyrimidine compound prepared in Experimental Example 42, the proportion of H1975 cells in the G2 phase showed a certain concentration-dependent upward trend. Compared with the control group (20.08% of cells in the G2 phase), the proportion of cells in the G2 phase in the 1 μM treatment group was 19.22%, which was not significantly changed, while the proportion of cells in the G2 phase in the 4 μM treatment group rose to 23.023%. In contrast, the proportion of cells in the G2 phase in the positive control AZD-9291 (1 μM) treatment group was 25.25%, indicating that the G2 phase blocking effect was more significant.

[0344] Effect of the pyrrolopyrimidine compound prepared in Experimental Example 42 on the content of reactive oxygen species in H1975 cells detected by the DCFH-DA probe:

[0345] The specific operation steps are as follows:

[0346] (1) Cells in the logarithmic growth phase were inoculated into a 6-well plate at a density of 2.0 x 10 5 cells per well and cultured in an incubator for 24 h.

[0347] (2) 3 mL of serum-free medium was added to each well, and then 300 μL of the pyrrolopyrimidine compound prepared in Experimental Example 42 (1, 5 μM) and the positive drug (AZD9291, 1 μM) of the specified concentration were added, respectively, with no addition of the drug as the blank control group. After culture for the specified time, the old culture solution was discarded, and two PBS washes were performed before the staining solution was added.

[0348] (3) After three PBS washes, 1 mL of culture solution containing DCFH-DA was added to each well.

[0349] (4) Excess formaldehyde was removed, and two PBS washes were performed.

[0350] (5) Finally, 1 mL / well of crystal violet was added for staining, and the cells were allowed to stand for 15 minutes.

[0351] (6) After the last two PBS washes, the fluorescence microscope was used for observation and photography.

[0352] The detection results are shown in Figure 5 .

[0353] Figure 5 As can be seen, the green fluorescence signal of the H1975 cells in the blank control group was weak, and the ROS production level was extremely low. After treatment with the pyrrolopyrimidine compound prepared in Experimental Example 42 at a concentration of 1 μM, the green fluorescence in the cells was slightly enhanced, indicating that the ROS level was increased. When the concentration was increased to 5 μM, the intensity of the green fluorescence in the cells was increased, indicating that the ROS level showed a significant upward trend.

[0354] The influence of the pyrrolopyrimidine compound prepared in Experimental Example 42 on the mitochondrial membrane potential of cancer cells was detected by using the JC-1 method.

[0355] The specific operation steps are as follows:

[0356] (1) The cell density of H1975 cell suspension was 4x10 4 cells / mL, and 1 mL of the cell suspension was added to each well of a 24-well plate, and the cells were cultured in a cell incubator for 24 h.

[0357] (2) The original culture solution was removed, and the cells were washed twice with PBS. 1 mg of the pyrrolopyrimidine compound prepared in Experimental Example 42 was dissolved in 20 μL of DMSO, and then serum-free medium was added to prepare a solution with a concentration of 1 μM and 2 μM. 1 mL of the drug solution was added to each well, and the plate was gently shaken to mix the solution. The plate was then placed in a cell incubator and cultured for 12 h. A blank control group without the drug solution was used, and AZD-9291 with a concentration of 1 μM was used as a positive control group.

[0358] (3) The culture solution was removed, and the cells were washed twice with 1 mL of PBS. Then, 1 mL of JC-1 working solution (50 uL of JC-1 (200x): 8 mL of ultrapure water) was added, and the plate was mixed thoroughly and placed in a cell incubator for 20 min.

[0359] (4) The working solution was removed, and the cells were washed twice with 1x JC-1 staining buffer.

[0360] (5) 2 mL of 200x JC-1 staining buffer was added, and the plate was placed under a fluorescence microscope for observation and photography.

[0361] Detection results Figure 6 .

[0362] The stability of the mitochondrial membrane potential (MPP) is crucial for the normal physiological function of cells, and a decrease in the mitochondrial membrane potential often indicates that the cells are moving towards apoptosis. The JC-1 fluorescent probe can well reflect this change: when the mitochondrial membrane potential is normal, the cells exhibit red fluorescence, and when the potential decreases, the fluorescence changes to green, so it can be used to directly determine whether the cells are damaged or undergoing apoptosis. Figure 6 As shown, the cells in the control group remained in a healthy state, and the mitochondrial membrane potential was stable, so the fluorescence signal was mainly red. When the cells were exposed to 1 μM of AZD-9291, part of the fluorescence changed from red to green, indicating that the mitochondrial membrane potential decreased, and some cells may have begun to undergo apoptosis. In contrast, the pyrrolopyrimidine compound prepared in Experimental Example 42 caused more obvious green fluorescence in the treatment groups at concentrations of 1 μM and 2 μM, especially at a concentration of 2 μM, where the green fluorescence was more obvious, indicating that the mitochondrial membrane potential decreased more sharply, and the degree of cell damage or apoptosis was deeper. This indicates that the pyrrolopyrimidine compound prepared in Experimental Example 42 can induce cell death by affecting mitochondrial function, and to some extent, it exhibits strong biological activity.

[0363] The above experimental results show that the pyrrolopyrimidine compound prepared in Experimental Example 42 of the present application is expected to be a potential EGFR inhibitor.
