Description

[Technical Field]

[0001] The present invention belongs to the field of medicinal chemistry, and specifically relates to naphthylamide compounds as protein kinase inhibitors, their preparation methods, and their application in the treatment and / or prevention of diseases associated with the biological activity of said protein kinases. [Background technology]

[0002] Vascular endothelial growth factor receptors (VEGFRs) are a family of receptor tyrosine kinases (RTKs) that includes three structurally similar transmembrane protein members: 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 both endothelial and non-endothelial cells, including tumor cells, and these receptors can bind to five natural ligands, including VEGF-A, VEGF-B, VEGF-C, VEGF-D, and placental growth factor (PlGF). Among them, VEGF-A plays an indispensable role in the process of angiogenesis and maintenance, and VEGF-C and VEGF-D are ligands that mediate lymphangiogenesis. Among all receptors, VEGFR2 plays the most major role and is crucial for regulating angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis.

[0003] Because the diffusion limit of oxygen in mammalian tissue is approximately 100–200 μM, the growth diameter of metabolically active solid tumor tissue is limited to within 0.2–2.0 mm due to oxygen deficiency if new blood vessels do not provide sufficient blood oxygen supply through tissue diffusion alone. Therefore, antiangiogenesis has become an effective treatment for various solid tumors (Adair TH, et al., Angiogenesis, Morgan & Claypool Life Sciences: San Rafael, CA, USA, 2010).

[0004] Currently, there are two main classes of approved drugs targeting the VEGF-VEGFRs pathway for tumor angiogenesis. One class is monoclonal antibodies, such as bevacizumab, which was first approved in 2004, and ramucirumab, which was approved in 2014. The other class is VEGFRs small molecule inhibitors, which mainly include sorafenib, axitinib, apatinib, sunitinib, regorafenib, vandetanib, pazopanib, lenvatinib, ponatinib, cabozantinib, and fruquintinib.

[0005] Antiangiogenic drugs have significantly improved the therapeutic prospects for several types of solid tumors, but hypertension is one of the most common toxic side effects of VEGF-VEGFR inhibitors, with nearly 100% of patients treated with these drugs experiencing elevated blood pressure. Studies have shown that hypertension caused by VEGF-VEGFR inhibitors is a mechanism-dependent target toxicity that typically leads to dose adjustments or treatment discontinuation during the course of treatment (Camarda N, et al., Curr. Oncol. Rep., 2022 Apr;24(4):463-74).

[0006] Aurora kinases (AURKs) are a class of serine / threonine protein kinases that play an important role in regulating the cell cycle. The human AURKs family contains three members: Aurora kinase A (Aurora A), Aurora kinase B (Aurora B), and Aurora kinase C (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).

[0007] Aurora B is overexpressed in tumors derived from many different tissues compared with normal tumor tissues. This kinase, encoded by the AURORA B gene located on chromosome 17 and also known as AIK2, AIM1, ARK2, AIRK2, IPL1, STK1, STK5, and STK12, phosphorylates histone H3 at Ser10, which is crucial for sister chromatid separation. Exogenous overexpression of Aurora B can increase histone H3 phosphorylation and chromosomal aneuploidy in normal cells, and injection of these Aurora B-overexpressing cells into BALB / c nu / nu mice resulted in tumor formation, indicating that Aurora B functions as a driver of tumor development (Ota T, et al., Cancer Res., 2002, 62(18):5168-77).

[0008] Inhibition of Aurora B, an antitumor target, can disrupt abnormal kinetochore-microtubule connections, prevent chromosome alignment and segregation, and even cause mitotic catastrophe and cell apoptosis. Loss of Aurora B kinase activity can lead to cytokinesis failure, resulting in tetraploidy (or polyploidy), and this severe genomic instability ultimately leads to cell death. Because Aurora B is expressed only in dividing and proliferating cells and remains largely stable in normal cells, targeted inhibition of Aurora B offers strong selectivity for actively dividing tumor cells, a significant advantage over other nonspecific cytotoxic drugs.

[0009] To date, no AURK inhibitors have been approved for sale worldwide. However, clinical studies of such inhibitors are currently active, including pan-AURK inhibitors such as VX-680 / MK-0475 (Tozasertib), PHA-793358 (Danusertib), AT-9283, AMG 900, KW-2449, ABT-348 (Ilorasertib), and TT00420; selective Aurora A inhibitors such as MLN8237, ENMD2076, VX-689, and LY3295668; and selective Aurora B inhibitors such as AZD1152 (Barasertib) and Chiauranib (Jing X, et al., Expert. Opin. Ther. Pat., 2021, 31(7):625-44). Existing evidence indicates that selective Aurora A or Aurora B inhibitors have better druggability compared to pan-AURKs inhibitors, in part because they can avoid more toxicity.

[0010] Thiauranib, developed by Shenzhen Weixin Biotechnology Co., Ltd., is a small molecule inhibitor targeting various kinase channels, including VEGFR, PDGFR, and Aurora B, and is currently undergoing clinical trials for tumor treatment. According to the results of a Phase I clinical trial of thiauranib, a dose-limiting toxicity (DLT) of thiauranib occurred in the 65 mg group, showing grade 3 hypertension, a toxicity associated with VEGFR pathway inhibition. The recommended dose for Phase II clinical trials is 50 mg, administered once daily at this dose, with a maximum blood drug exposure (C ) of 100 mg after 28 days of continuous administration. max ) was approximately 2.6 μM, and the steady-state blood drug exposure (C trough ) is approximately 1 μM (Sun Y, et al., J. Hematol. Oncol., 2019, 12(1):9). In humans, DLTs of tiauranib are associated with inhibition of the VEGFR pathway, suggesting that the VEGFR pathway may be the dominant pathway for tiauranib's in vivo efficacy. In vitro cytological studies have shown that tiauranib exhibits relatively weak inhibitory activity against Aurora B kinase at concentrations of 1–3 μM (equivalent to in vivo drug exposure levels), suggesting that the drug's targeting mechanism may be limited in the treatment of Aurora B kinase-dependent tumors. Therefore, the development of multi-targeted kinase inhibitors with stronger selectivity for Aurora B kinase and greater potency in inhibiting Aurora B than VEGFR2 may offer better therapeutic efficacy for Aurora B kinase-dependent tumors within similar human exposure and maximum tolerated dose (MTD) ranges. Summary of the Invention [Problem to be solved by the invention]

[0011] In the prior art, Aurora B kinase inhibitory activity is relatively weak, but strong VEGFR2 inhibitory activity can cause toxic side effects such as hypertension. In particular, the relatively weak selectivity of Aurora B kinase over VEGFR2 limits the therapeutic effect in treating tumors associated with the biological activity of Aurora B kinase. At the same time, in view of the need for treatment of primary and metastatic tumors of the central nervous system, therapeutic drugs must be able to cross the blood-brain barrier and achieve effective intracranial exposure to exert their anti-tumor effects. Therefore, the object of the present invention is to provide compounds with higher selectivity for Aurora B kinase compared to VEGFR2, which have more significant inhibitory activity against Aurora B kinase at the cellular level under conditions of blood drug-reachable exposure, thereby achieving the overall benefits of better therapeutic efficacy / safety for related diseases. At the same time, the compounds of the present invention have the ability to cross the blood-brain barrier well, making them suitable for the treatment and / or prevention of central nervous system diseases.

[0241] Other compounds of the present invention may also be prepared by following analogous steps in the above examples.

[0242] In vitro biological evaluation Example A: Inhibitory activity and relative selectivity test of the compounds of the present invention against Aurora B and VEGFR2 kinase Preparation of DMSO working solutions of gradient concentrations of compounds: Compounds were prepared in 0.2 mM DMSO solutions and diluted in DMSO to 10 gradient concentrations (corresponding to final compound concentrations 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 in the reaction system).

[0243] Aurora B kinase and VEGFR2 inhibitory activity test: The half inhibitory concentration (IC) of compounds against Aurora B kinase and VEGFR2 was measured using the HTRF KinEASE-TK kit (Cisbio, Catalog No. 62TK0PEC) and the HTRF KinEASE-STK kit (Cisbio, Catalog No. 61ST2BLE). 50) were tested. 2x kinase & metal solution (Aurora B / catalog number 05-102 and VEGFR2 / catalog number 08-191 were both purchased from Carna) and 2x substrate & ATP solution (substrates S2 and TK were used for Aurora B and VEGFR2, respectively) were prepared according to the reagent kit instructions. 25 nL of each concentration gradient working solution of the compound to be measured and 2.5 μL of 2x kinase & metal solution were added to each well of a 384-well plate. The plate was blocked with blocking film, mixed uniformly, centrifuged, and then incubated at 25°C for 10 minutes. Next, 2.5 μL of 2x substrate & ATP solution was added to each well, and the plate was again incubated at 25°C for 30 minutes. Finally, 5 μL of 2×XL665 & Antibody kinase detection reaction solution was added to each well, and after incubation at 25° C. for 60 minutes, the fluorescent signals of each well were read at wavelengths of 665 nm and 620 nm using a microplate reader.

[0244] The 665 nm / 620 nm fluorescence signal ratio (X) of each well was calculated. The compound-free wells were used as negative references (Y) and enzyme-free wells as positive references (Z). The inhibitory rate of the compound against the corresponding kinase in each test well was calculated using the formula: Inhibition (%) = 100% - (XZ) / (YZ) × 100%. The half inhibitory concentration (IC) of each compound against the corresponding kinase was calculated using GraphPad 7.0 software. 50 ) was calculated.

[0245] The relative selectivity of inhibitory potency against Aurora B kinase was determined by the IC 50 and IC for Aurora B 50 The ratio of IC 50-VEGFR2 / I C 50-Aurora B The larger the ratio, the stronger the inhibitory potency of the compound against Aurora B kinase compared to VEGFR2. Specific data are shown in Table 2 below.

[0246] [Table 2]

[0247] Compounds No. 31 (Chiauranib) and No. 32 are examples disclosed in Patent CN101906076A, and the present inventors have synthesized these two compounds by referring to the synthetic methods therein for use as control molecules. The structural formulas of these two compounds are as follows:

[0248] [ka] The results in Table 2 show that the compounds of the present invention have excellent Aurora B kinase inhibitory activity and, at the same time, extremely high Aurora B kinase selectivity compared to VEGFR2. Specifically, compared with control molecule 01 (Chiauranib), control molecule 02, and control examples I-7, I-11, I-12, I-13, and I-14, the compounds of the present invention not only have stronger inhibitory effects on Aurora B kinase, but also have Aurora B IC50s of 10 nM or less. At the same time, the compounds of the present invention have extremely high Aurora B kinase selectivity compared to VEGFR2, with IC50-VEGFR2 / IC50-Aurora B being 7 or greater, achieving an unexpected technical effect.

[0249] Example B: Testing the effect of compounds of the invention on tumor cell cycle Inhibition of Aurora B kinase activity in tumor cells leads to the failure of cytokinesis due to the disruption of chromosome alignment and segregation, resulting in the formation of tetraploids or polyploids, and severe genomic instability and mitotic catastrophe, leading to apoptosis. The fluorescent dye propidium iodide (PI), which specifically binds to nucleic acids, can be used to measure intracellular DNA content, which can then be classified into sub-G0 / G1 (apoptosis), G0 / G1, S, G2 / M (tetraploid), and polyploid states. Sub-G0 / G1 is a state in which the DNA content is less than 2N and is generally considered to be a state in which cells are undergoing apoptosis (random DNA degradation, cell membrane permeation), while polyploid is a state in which the DNA content is greater than 4N.

[0250] Testing Procedure: Human acute lymphoblastic leukemia cells Molt-4 (CRL-1582) were purchased from the American Type Culture Collection (ATCC). Molt-4 cells were cultured in suspension and counted during logarithmic growth. 6 Cells were seeded into 6-well plates at 100 cells / well and cultured overnight as usual. Test compounds were prepared in 1 mM and 3 mM DMSO solutions, which were then further diluted 50-fold with culture medium. Finally, the above solutions were added to the culture system at a volume ratio of 1:19 so that the final compound concentration in each well reached 1 μM or 3 μM, respectively. After 48 hours of culture, the cells were collected by centrifugation. Each cell sample was resuspended in 300 μl of PBS and added dropwise to 700 μl of pre-chilled absolute ethanol. The mixture was then gently inverted several times to mix evenly. Cell collection and fixation were completed, and the samples were then left at 4°C for at least 12 hours before flow cytometry analysis.

[0251] PBS was mixed uniformly with 10 mg / mL PI stock solution and 10 mg / mL RNase A solution at a ratio of 1000:5:2 to prepare the working solution. The fixed cell samples were centrifuged at 1000 rpm at 4°C for 10 minutes, the supernatant was removed by aspiration, and the cells were washed twice with PBS and resuspended in the working solution at 300 μL per tube. After incubation at 37°C for 30 minutes in the dark, the cells were filtered through a 200-mesh stainless steel mesh, and the filtrate was subjected to flow cytometric cell cycle analysis (10,000 cells were counted per sample).

[0252] Histograms showing DNA content were obtained by flow cytometry, and the cycle distribution in each sample was analyzed using the flow data analysis software FlowJo. The mean (X) and standard deviation (SD) were calculated, and the data were expressed as X ± SD. After treating Molt-4 with different doses of the test compounds, the proportions of apoptotic cells, tetraploids, and polyploids were shown in Table 3 below.

[0253] [Table 3]

[0254] The results in Table 3 show that, at both the 1 μM and 3 μM doses, the compounds of the present invention have significantly improved effects on inducing tetraploidy, polyploidy, and apoptosis in Molt-4 cells compared with the control molecule 01 (Chiauranib) and the control molecule 02. This demonstrates that the compounds of the present invention have a stronger inhibitory effect on Aurora B kinase activity in tumor cells, thereby affecting the cell cycle of tumor cells and achieving overall benefits of better therapeutic efficacy / safety against related diseases.

[0255] Example C Brain penetration test of compounds of the present invention To test whether the compounds of the present invention can cross the blood-brain barrier (BBB), 6-week-old B / C female mice (purchased from the Guangdong Provincial Medical Animal Experimental Center) were used. The compounds of the present invention were prepared in a solvent containing 5% dimethyl sulfoxide, 60% 1,3-propanediol, and 35% purified water. 5 mg / kg of the compounds were administered intragastrically. Four hours after administration, the animals were sacrificed and blood and brain tissue were collected. Blood was anticoagulated with K2-EDTA and centrifuged at 5000 rpm for 5 minutes to separate the plasma. Brain tissue was accurately weighed and homogenized in a fixed amount of phosphate buffered saline (PBS). The biological samples were frozen and stored at -80°C for analysis. After sample extraction, the compound concentrations were measured using a liquid chromatography-mass spectrometer (LC-MS / MS). Brain penetration is defined as the ratio of the compound concentration in brain tissue to that in plasma.

[0256] [Table 4]

[0257] As shown by the results in Table 4, in the brain penetration detection, 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 achieve effective blood concentrations in brain tissue, and can be used for the treatment and prevention of central nervous system-related diseases.

PANC02 cells in the logarithmic growth phase and proliferating well were collected and cultured at a concentration of 0.9 × 10 6 The tumor was subcutaneously inoculated into the left side of a C57BL / 6 mouse at a concentration of 0.2 ml / cell. The major axis (a, mm) and minor axis (b, mm) of the tumor were measured using a caliper, and the tumor volume (V, mm) was calculated.3 ) is calculated as V=1 / 2a*b 2 Tumor volumes were measured 2-3 times a week using calipers. The average tumor volume in mice was 190 mm 3 Once the animals reached this level, they were divided into groups of 8 animals each. The day of grouping was Day 0 (i.e., Day 0). They were divided into a total of 4 groups: the solvent control group (0.2% CMC-Na aqueous solution), compound I-9 group (10 mg / kg / day), control molecule 01 group (Chiauranib) (10 mg / kg / day), and control molecule 02 group (10 mg / kg / day). All 4 groups were intragastrically administered once daily, and the experiment was terminated on the day of the final administration.

[0259] The tumor volume results were expressed as the mean and standard deviation (Mean ± SEM). Comparisons between two groups were detected using the Mann-Whitney test. A p<0.05 was considered statistically significant. The tumor volume inhibition rate (TGI) was calculated as follows: TGI (%) = [1-(Ti-T0) / (Vi-V0)] × 100%. (Ti: mean tumor volume of the treatment group on day i of administration; T0: mean tumor volume of the treatment group on day 0 of administration; Vi: mean tumor volume of the vehicle control group on day i of administration; and V0: mean tumor volume of the vehicle control group on day 0 of administration.) The average tumor volume and tumor volume inhibition rate of mice in each group on different days of administration are shown in Table 5, and the statistical results of the average tumor volume are shown in Figure 1.

[0260] [Table 5]

[0261] As can be seen from Figure 1, on the 9th day of group administration, the tumor volume of mice in the compound I-9 group was significantly reduced compared to the control molecule 01 (Chiauranib) group (p<0.01). Compared to the control molecule 02 group, the tumor volume of mice in the compound I-9 group was significantly reduced (p<0.05). Compared to the solvent control group, the tumor volume of mice in the compound I-9 group was significantly reduced (p<0.001).

[0262] As can be seen from Table 5, the tumor volume inhibition rate of the representative compound I-9 group (TGI 114.0%) was significantly superior to that of the control molecule 01 (Chiauranib) group (TGI 74.6%) and the control molecule 02 group (TGI 68.9%).

[0263] In summary, the compounds of the present invention have excellent in vivo antitumor effects and can clearly inhibit tumor growth.
