Description

[0001] This application is a divisional application of the Chinese invention patent application with the application date of December 27, 2023, application number CN202311820205.X, and invention name “A naphthamide compound, its preparation method and its application”. Technical Field

[0002] The present invention belongs to the field of pharmaceutical chemistry, and specifically relates to a naphthamide compound as a protein kinase inhibitor, a preparation method thereof, and an application thereof in treating and / or preventing diseases associated with the biological activity of the protein kinase. Background Art

[0003] Vascular endothelial growth factor receptors (VEGFRs) are a family of receptor tyrosine kinases (RTKs) that include three structurally similar transmembrane protein members, namely: VEGFR1 (also known as feline McDonough sarcoma (fms)-related tyrosine kinase-1, Flt-1), VEGFR2 (also known as kinase insert domain receptor (KDR)) and VEGFR3 (also known as Flt-4) (Moser C, et al., Clin. Colorectal Cancer., 2007, 6 (8): 564-71). VEGFRs are expressed in endothelial cells, non-endothelial cells including tumor cells, and this type of receptor can bind to five natural ligands including VEGF-A, VEGF-B, VEGF-C, VEGF-D and PlGF (Placental Growth Factor). Among them, VEGF-A plays an irreplaceable role in the process of angiogenesis and maintenance, while VEGF-C and VEGF-D are ligands that mediate lymphangiogenesis. Among all receptors, VEGFR2 plays the most important role and is crucial in the regulation of angiogenesis, vascular development, vascular permeability and embryonic hematopoiesis.

[0004] Since the diffusion limit of oxygen in mammalian tissue is about 100-200 μM, if there is no new blood vessels to provide sufficient blood oxygen supply and only tissue diffusion is relied on, the growth diameter of metabolically active solid tumor tissue will be limited to 0.2-2.0 mm due to hypoxia. Therefore, anti-angiogenesis has become an effective treatment for various solid tumors (Adair TH, et al., Angiogenesis, Morgan & Claypool Life Sciences: San Rafael, CA, USA, 2010.).

[0005] At present, there are two main types of approved drugs targeting tumor angiogenesis and VEGF-VEGFRs pathway: one is monoclonal antibodies, such as Bevacizumab, which was first approved in 2004, and Ramucirumab, which was approved in 2014. The other is VEGFRs small molecule inhibitors, mainly including Sorafenib, Axitinib, Apatinib, Sunitinib, Regorafenib, Vandetanib, Pazopanib, Lenvatinib, Ponatinib, Cabozantinib, Fruquintinib, etc.

[0006] Anti-angiogenic drugs have greatly improved the treatment prospects of various solid tumors, but hypertension is one of the most common toxic side effects of VEGF-VEGFRs inhibitors, and almost 100% of patients treated with this type of drug experience elevated blood pressure. Studies have shown that hypertension caused by VEGF-VEGFRs inhibitors is a mechanism-dependent target toxicity, which usually leads to dose adjustments or interruptions during treatment (Camarda N, et al., Curr. Oncol. Rep., 2022Apr; 24(4): 463-74).

[0007] Aurora kinases (AURKs) are an important class of serine / threonine protein kinases that regulate the cell cycle. The human AURKs family includes three members: Aurora A, Aurora B, and Aurora C. In all somatic cells, only Aurora A and Aurora B are expressed at detectable levels (Tang A, et al., Oncotarget., 2017, 8: 23937-54).

[0008] Aurora B is overexpressed in tumors of many different tissue sources relative to normal adjacent tissues. This kinase is encoded by the AURORA B gene located on chromosome 17, also known as AIK2, AIM1, ARK2, AIRK2, IPL1, STK1, STK5 and STK12. Its phosphorylation and modification of the Ser10 site of histone H3 is essential for sister chromatid separation. Exogenous overexpression of Aurora B can increase the phosphorylation of histone H3 and chromosomal aneuploidy in normal cells, and injection of these Aurora B overexpressing cells into BALB / c nu / nu mice will lead to tumor formation, indicating that Aurora B has a driving effect on tumorigenesis (Ota T, et al., Cancer Res., 2002, 62(18): 5168-77).

[0009] Taking Aurora B as an anti-tumor target and inhibiting its activity can block the abnormal connection between kinetochores and microtubules, prevent the arrangement and separation of chromosomes, and then cause mitotic catastrophes and cell apoptosis. In addition, the loss of Aurora B kinase activity will lead to the failure of cytokinesis and the formation of tetraploidy (or polyploidy). Such severe genomic instability will eventually lead to cell death. Aurora B is only expressed in dividing and proliferating cells and is mostly in a stable state in normal cells. Therefore, targeted inhibition of Aurora B has a strong selectivity for tumor cells with active division and proliferation, and will have greater advantages compared with other non-specific cytotoxic drugs.

[0010] To date, no AURKs inhibitors have been approved for marketing worldwide, but clinical research on this type of inhibitor is currently relatively active, including AURKs pan-inhibitors such as VX-680 / MK-0475 (Tozasertib), PHA-793358 (Danusertib), AT-9283, AMG 900, KW-2449, ABT-348 (Ilorasertib) and TT00420, Aurora A selective inhibitors such as MLN8237, ENMD 2076, VX-689 and LY3295668, and Aurora B selective inhibitors such as AZD1152 (Barasertib) and Chiauranib (Jing X, et al., Expert. Opin. Ther. Pat., 2021, 31(7): 625-44.). Existing evidence has shown to some extent that Aurora A or Aurora B selective inhibitors can avoid more toxicity than AURKs pan-inhibitors and therefore have better drugability.

[0011] Chiauranib is a small molecule inhibitor developed by Shenzhen Chipscreen Biotech Co., Ltd. that targets multiple kinase pathways such as VEGFR, PDGFR, and Aurora B. Clinical trials for tumor treatment are ongoing. According to the results of the Phase I clinical trial of Chiauranib, the dose-limiting toxicity (DLT) of Chiauranib occurred in the 65mg group, which manifested as grade 3 hypertension, a toxicity associated with VEGFR pathway inhibition. The Phase II clinical recommended dose is 50mg. Under this dose condition, the drug is administered once a day, and the highest blood drug exposure (C max ) is about 2.6μM, and the steady-state blood drug exposure (C trough ) is about 1μM (Sun Y, et al., J. Hematol. Oncol., 2019, 12(1): 9.). The DLT of sioroni in humans is related to the inhibition of the VEGFR pathway, suggesting that the VEGFR pathway may be the dominant pathway for the in vivo efficacy of sioroni. According to in vitro cellular experiments, sioroni has relatively weak inhibitory activity against Aurora B kinase under 1-3μM conditions (equivalent to the in vivo drug exposure level), suggesting that there may be limited drug target mechanism in the treatment of Aurora B kinase-dependent tumors. Therefore, the development of multi-target kinase inhibitors that are more selective for Aurora B kinase and relatively more potent in inhibiting Aurora B than VEGFR2 may achieve better efficacy against Aurora B kinase-dependent tumors within a similar human exposure and maximum tolerated dose (MTD) range. Summary of the invention

[0012] Problems to be solved by the invention:

[0013] In view of the relatively weak inhibitory activity of Aurora B kinase in the prior art, and the excessive inhibitory activity of VEGFR2 will produce toxic side effects such as hypertension, especially when the selectivity of Aurora B kinase relative to VEGFR2 is weak, the full play of the therapeutic effect in the treatment of tumors related to the biological activity of Aurora B kinase is limited. At the same time, in view of the treatment requirements for primary and metastatic tumors of the central nervous system, the therapeutic drug needs to be able to cross the blood-brain barrier and reach an effective exposure amount in the brain to exert an anti-tumor effect. Therefore, the purpose of the present invention is to provide a compound with higher selectivity for Aurora B kinase relative to VEGFR2, and the related compound has a more significant inhibitory activity on Aurora B kinase at the cellular level under the condition of blood drug accessible exposure, which can achieve better efficacy / safety comprehensive benefits for related diseases. At the same time, the compound of the present invention has a good ability to cross the blood-brain barrier and is suitable for the treatment and / or prevention of central nervous system diseases.

[0456] Prepare DMSO working solutions of compound gradient concentrations: prepare the compound into 0.2 mM DMSO solution, and dilute it into 10 working solutions of gradient concentrations with DMSO (corresponding to final concentrations of the compound in the reaction system of 1000 nM, 300 nM, 100 nM, 30 nM, 10 nM, 3 nM, 1 nM, 0.3 nM, 0.1 nM, and 0.03 nM).

[0457] Aurora B kinase and VEGFR2 inhibitory activity test: The half inhibitory concentration (IC50) of the compound on Aurora B kinase and VEGFR2 was tested by HTRF KinEASE-TK kit (Cisbio, Cat#62TK0PEC) and HTRF KinEASE-STK kit (Cisbio, Cat#61ST2BLE), respectively. 50 ). According to the instructions of the kit, prepare 2×kinase&Metal solution (Aurora B / Cat#05-102 and VEGFR2 / Cat#08-191 are purchased from Carna) and 2×Substrate&ATP solution (substrates S2 and TK are used for Aurora B and VEGFR2, respectively). Add 25nL of working solution of the compound to be tested at each gradient concentration and 2.5μL of 2×kinase&Metal solution to each well of the 384-well plate, seal the plate with a sealing film, mix well, centrifuge, and incubate at 25°C for 10 minutes. Then add 2.5μL of 2×Substrate&ATP solution to each well and incubate again at 25°C for 30 minutes. Finally, add 5μL of 2×XL665&Antibody kinase detection reaction solution to each well, incubate at 25°C for 60 minutes, and read the fluorescence signals of each well at 665nm and 620nm wavelengths using an enzyme reader.

[0458] The 665 nm / 620 nm fluorescence signal ratio (X) of each well was calculated, and the well without compound was used as the negative reference (Y) and the well without enzyme was used as the positive reference (Z). The inhibition rate of the compound in each test well on the corresponding kinase was calculated by the formula: Inhibition (%) = 100% - (XZ) / (YZ) × 100%, and the half inhibitory concentration (IC) of each compound on the corresponding kinase was calculated by GraphPad 7.0 software. 50 ).

[0459] Relative selectivity of Aurora B kinase inhibition, measured by IC values ​​of compounds against VEGFR2 50 With IC for Aurora B 50 The ratio of IC 50-VEGFR2 / IC 50-Aurora B The larger the ratio, the stronger the compound's inhibitory effect on Aurora B is relative to that on VEGFR2. The specific data are shown in Table 2 below:

[0460] Table 2 Inhibitory activity and relative selectivity of the compounds of the present invention on Aurora B and VEGFR2 kinases

[0461]

[0462] Compound No. 31 (Chiauranib) and Compound No. 32 are examples disclosed in patent CN101906076A. The inventors synthesized the two compounds with reference to the synthesis method therein for use as reference molecules. The structural formulas of the two compounds are as follows:

[0463]

[0464] The results in Table 2 show that the compounds of the present invention have excellent Aurora B kinase inhibitory activity and very high Aurora B kinase selectivity relative to VEGFR2. Specifically, compared with the control molecule 01 (Chiauranib), the control molecule 02, and the control examples I-7, I-11, I-12, I-13, and I-14, the compounds of the present invention not only have a stronger inhibitory effect on Aurora B kinase in terms of activity, with an IC50 of Aurora B below 10 nM, but also have very high Aurora B kinase selectivity relative to VEGFR2, with IC50-VEGFR2 / IC50-Aurora B being above 7, achieving unexpected technical effects.

[0465] Example B Testing of the Effects of the Compounds of the Invention on Tumor Cell Cycle

[0466] When the activity of Aurora B kinase in tumor cells is inhibited, the arrangement and separation of chromosomes are blocked, resulting in the failure of cytokinesis to form tetraploid or polyploid cells, and the severe instability of the genome and mitotic catastrophes cause cell apoptosis. The fluorescent dye propidium iodide (PI) that specifically binds to nucleic acids can be used to calibrate the DNA content in cells, so that the cell state can be distinguished into sub-G0 / G1 (apoptosis), G0 / G1, S, G2 / M (tetraploid) and polyploid states. Among them, sub-G0 / G1 means that the DNA content is less than 2N, and it is generally believed that the cells are in the process of apoptosis (random DNA degradation, cell membrane permeability); polyploid means that the DNA content is greater than 4N.

[0467] Experimental process:

[0468] Human acute lymphoblastic leukemia cell Molt-4 (CRL-1582) was purchased from American Type Culture Collection (ATCC). Molt-4 cells in suspension culture and logarithmic growth phase were collected and counted. 6 Cells were inoculated into six-well plates and cultured overnight. The test compound was prepared into 1mM and 3mM DMSO solutions, and then the DMSO solution was diluted 50 times with culture medium. Finally, the above solution was added to the culture system at a volume ratio of 1:19, so that the final concentration of the compound in each well reached 1μM or 3μM, respectively. After continuing to culture for 48 hours, the cells were collected by centrifugation. Each cell sample was resuspended in 300μl PBS and dripped dropwise into pre-cooled 700μl anhydrous ethanol, and then gently inverted several times to mix. At this point, the cell collection and fixation were completed. The samples were left to stand at 4°C for more than 12 hours before flow cytometric analysis.

[0469] Mix PBS with 10mg / mL PI stock solution and 10mg / mL RNase A solution at a ratio of 1000:5:2 to form a working staining solution. Centrifuge the fixed cell sample at 4°C, 1000rpm for 10 minutes, aspirate the supernatant and wash twice with PBS, and resuspend in the above working staining solution at 300μL per tube. After incubation at 37°C in the dark for 30 minutes, filter the cells with a 200-mesh stainless steel mesh, and load the filtrate for flow cytometry analysis (10,000 cells are counted for each sample).

[0470] The histogram showing the DNA content was obtained by flow cytometry, and the cycle distribution in each sample was analyzed by flow cytometry data analysis software FlowJo, and the mean (X) and standard deviation (SD) were calculated. The data were expressed as X±SD. After Molt-4 was treated with the test compounds at different doses, the apoptosis, tetraploidy and polyploidy ratios of the cells were shown in Table 3 below.

[0471] Table 3 Test results of the effects of the compounds of the present invention on the Molt-4 cell cycle

[0472]

[0473] The results in Table 3 show that: whether under the 1 μM dose condition or the 3 μM dose condition, compared with the control molecule 01 (Chiauranib) and the control molecule 02, the effect of the compound of the present invention on inducing tetraploidy, polyploidy and cell apoptosis in Molt-4 cells is significantly improved, indicating that the compound of the present invention has a stronger inhibitory effect on the Aurora B kinase activity in tumor cells, thereby affecting the cell cycle of tumor cells, which can achieve better efficacy / safety comprehensive benefits for related diseases.

[0474] Example C Brain Penetration Test of the Compounds of the Invention

[0475] In order to test whether the compound of the present invention can cross the blood-brain barrier (BBB), 6-week-old B / C female mice (purchased from Guangdong Medical Animal Experiment Center) were taken, and the compound of the present invention was formulated in a solvent containing 5% dimethyl sulfoxide, 60% 1,3-propylene glycol and 35% purified water. The compound of the present invention was administered by gavage at 5 mg / kg. The animals were killed 4 hours after administration, and blood and brain tissue were collected. The blood was anticoagulated with K2-EDTA, centrifuged at 5000rpm for 5 minutes, and plasma was separated. The brain tissue was accurately weighed, homogenized with a certain amount of phosphate buffered saline (PBS) solution, and the biological sample was frozen at -80°C for testing. After sample extraction, the compound concentration was determined by liquid chromatography-mass spectrometry (LC-MS / MS). Brain penetration is defined as the ratio of the compound concentration in brain tissue to the concentration in plasma.

[0476] Table 4 Brain penetration experimental data

[0477]

[0478] The results in Table 4 show that in the brain penetration test, the ratio of the compound concentration in brain tissue to the concentration in plasma of the compound of the present invention is significantly higher than that of the control molecule 01 (Chiauranib) and the control molecule 02. The test results show that the compound of the present invention has excellent brain barrier permeability, can pass through the blood-brain barrier, has the potential to reach an effective blood drug concentration in brain tissue, and can be used to treat and prevent central nervous system related diseases. Example D Antitumor efficacy experiment of the compound of the present invention in the pancreatic cancer model of PANC02 mice

[0479] The mouse PANC02 pancreatic cancer transplant tumor model was constructed. The experimental animals were C57BL / 6 mice (female, 6 weeks old), the tumor cells were PANC02 (mouse pancreatic cancer cells), and the cell culture medium was DMEM medium containing 1% double antibody and 10% fetal bovine serum. PANC02 cells in the logarithmic growth phase and growing well were collected and plated at 0.9×10 6 The tumors were inoculated subcutaneously on the left side of C57BL / 6 mice at a concentration of 0.2 mL. The long diameter (a, mm) and short diameter (b, mm) of the tumors and the tumor volume (V, mm) were measured with a vernier caliper. 3 ) The calculation formula is V = 1 / 2a*b 2 Tumor volume was measured 2-3 times a week using a vernier caliper. The average tumor volume reached 190 mm in mice 3 The mice were divided into groups and administered when the dose was higher than 10 mg / kg / day, with 8 mice in each group. The grouping day was Day 0 (i.e., Day 0), and the mice were divided into 4 groups, namely, the solvent control group (0.2% CMC-Na aqueous solution), the compound I-9 group (10 mg / kg / day), the control molecule 01 group (Chiauranib) (10 mg / kg / day), and the control molecule 02 group (10 mg / kg / day). All 4 groups were administered by gavage, once a day, for continuous administration, and the experiment was terminated on the day of the last administration.

[0480] Tumor volume results are expressed as mean ± SEM. Comparison between the two groups will be detected using the MannWhitney test. If p < 0.05, it is considered to be statistically significant. The calculation formula for tumor volume inhibition rate (TGI) is TGI (%) = [1-(Ti-T0) / (Vi-V0)] × 100%. (Ti: mean tumor volume of the treatment group on the i-th day of administration, T0: mean tumor volume of the treatment group on the 0th day of administration; Vi: mean tumor volume of the solvent control group on the i-th day of administration, V0: mean tumor volume of the solvent control group on the 0th day of administration)

[0481] The average tumor volume and tumor volume inhibition rate of each group of mice on different dosing days are shown in Table 5. The statistical results of the average tumor volume are shown in Figure 1 shown.

[0482] Table 5: Average tumor volume and tumor volume inhibition rate

[0483]

[0484] Depend on Figure 1It can be seen that: on the 9th day of group administration, compared with the control molecule 01 (Chiauranib) group, the tumor volume of mice in the compound I-9 group was significantly reduced (p<0.01).
