The present application claims the priority to Chinese invention patent application No. 202010471712.7 filed with China National Intellectual Property Administration on May 29, 2020, and Chinese invention patent application No. 202110003579.7 filed with China National Intellectual Property Administration on Jan. 5, 2021, the content of which are incorporated herein by reference in their entireties.
The present invention belongs to the field of medicine, and particularly relates to a pyrimidine compound, which is an AXL kinase inhibitor. The present invention also relates to use of the compound to treat diseases related to an AXL activity.
Receptor tyrosine kinase (RTK) is a multi-domain transmembrane protein that can be used as a sensor for an extracellular ligand. Ligand and receptor binding induces receptor dimerization and activation of its intracellular kinase domain, which in turn leads to the recruitment, phosphorylation and activation of a plurality of downstream signaling cascade reaction (Robinson, D R, et al., Oncogene, 19:5548-5557, 2000). So far, 58 RTKs, which have been identified from the human genome, can regulate a variety of cellular processes, including cell survival, growth, differentiation, proliferation, adhesion and movement (Segaliny, A. I., et al., J. Bone Oncol, 4:1-12, 2015).
AXL (also known as UFO, ARK and Tyro7) belongs to a TAM family of receptor tyrosine kinases, which also includes Mer and Tyro3. Among them, AXL and Tyro3 have the most similar gene structures, while AXL and Mer have the most similar tyrosine kinase domain amino acid sequences. Like other receptor tyrosine kinases (RTKs), the structure of the TAM family includes an extracellular domain, a transmembrane domain, and a conserved intracellular kinase domain. The extracellular domain of AXL has a unique structure in which immunoglobulin and type III fibronectin repeat units are juxtaposed, and which is reminiscent of the structure of neutrophil adhesion molecules. Members of the TAM family have a common ligand—Growth arrest specific protein 6 (Gas6), which can bind to all TAM receptor tyrosine kinases. After binding to Gas6, AXL will cause receptor dimerization and AXL autophosphorylation, thereby activating a plurality of downstream signal transduction pathways, and participating in a plurality of processes of tumorigenesis (Linger, R M, et al., Ther. Targets, 14 (10), 1073-1090, 2010; Rescigno, J. et al., Oncogene, 6(10), 1909-1913, 1991).
AXL is widely expressed in normal human tissues, such as monocytes, macrophages, platelets, endothelial cells, cerebellum, heart, skeletal muscles, liver, and kidney. AXL has the highest expression in myocardium and skeletal muscles, has relatively high expression in bone marrow CD34+ cells and stromal cells and has a very low expression in normal lymphoid tissues (Wu Y M, Robinson D R, Kung H J, Cancer Res, 64(20), 7311-7320, 2004; hung B I, et al., DNA Cell Biol, 22(8), 533-540, 2003). In the study of many cancer cells, it is found that AXL genes are overexpressed or ectopically expressed in hematopoietic cells, interstitial cells and endothelial cells. In various types of leukemia and most solid tumors, the overexpression of AXL kinase is particularly prominent. By inhibiting the AXL receptor tyrosine kinases, pro-survival signals of tumor cells can be reduced, the invasion ability of tumors can be blocked, and the sensitivity of targeted drug therapy and chemotherapy can be increased. Therefore, finding an effective AXL inhibitor is an important direction of current tumor-targeted drug research and development.

The compound and the positive drug are vortexed with a suitable solvent and then ultrasonicated to completely dissolve the compound. Then, an appropriate volume of citric acid buffer is slowly added, and the mixed solution is vortexed to make the solution mixed uniformly to obtain administrative formulations having concentrations of 0.1, 0.5, and 1 mg-mL−1.
Solvent control group: PEG400 & citric acid buffer (20:80, v:v).
The modeled mice are randomly divided into groups (n=6), and administrated with the relevant compounds and positive drugs on the day of grouping. After 21 days or after the tumor volume of the solvent control group reaches 2000 mm3, the experiment is terminated (whichever reaches the index first), and the administration volume is 10 mL-kg−1. Both the compound and the positive drug are administered by gavage, once a day. After the experiment starts, the tumor diameter and animal body weight are measured twice a week, and the tumor volume is calculated.
The tumor volume(TV) calculation formula is: tumor volume(mm3)=l×w2/2,
wherein l represents a long diameter (mm) of the tumor; w represents a short diameter (mm) of the tumor.
The calculation formula of relative tumor volume(RTV) is: RTV=TVt/TVinitial
wherein TVinitial is the tumor volume measured at the time of grouping and first administration; TVt is the tumor volume at each measurement during administration.
The calculation formula of tumor growth inhibition rate TGI(%) is: TGI=100%×[1−(TVt(T)−TVinitial(T))/(TVt(C)−TVinitial(C))]
wherein TVt(T) represents the tumor volume of treatment group at each measurement; TVinitial(T) represents the tumor volume of treatment group measured at the time of grouping and first administration; TVt(C) represents the tumor volume of solvent control group at each measurement; TVinitial(C) represents the tumor volume of the solvent control group measured at the time of grouping and first administration.
The calculation formula of relative tumor proliferation rate (% T/C) is: % T/C=100%×(RTVT/RTVC)
wherein RTVT represents RTV of treatment group; RTVC represents RTV of solvent control group.
The test data is calculated and subjected to related statistical treatment with Microsoft Office Excel 2007 software.
The experimental results are shown in Table 3:
Each compound is prepared with DMSO into a 10 mg/mL stock solution.
Preparation of mixed solvent: Tween 80: PEG400: Water=1:9:90 (v/v/v)
450 μl of the compound DMSO stock solution with a concentration of 10 mg/nmL is accurately sucked into a glass bottle, and added with an appropriate volume of DMSO and mixed solvent, wherein a ratio of the solvent in the final formulation is DMSO: mixed solvent (v/v)=10:90. The mixed solution is vortexed (or ultrasonically treated), and dispersed uniformly to obtain 4.5 mL. administration test solutions with a concentration of 1 mg/nL, respectively.
Male 6-10 week old ICR mice (sourced from: Beijing Vital River Laboratory Animal Technology Co., Ltd.) are taken, 6 mice in each group. The mice are fasted overnight and fed 4 h after the administration. On the day of the experiment, the mice are administrated with 10 mg-kg1 of compound test solution by gavage. After administration, about 100 μL of blood is harvested from the orbits of the mice at 0 min, 5 mmn, 15 mmn, 30 min, 14 h 2 h, 4 h, 8 h, and 24 h, and placed in EDTA-K2 anticoagulant tubes. The whole blood sample is centrifuged at 1500 to 1600 g for 10 mm, and the plasma obtained by separation is stored in a refrigerator at −40 to −20° C. for biological sample analysis. The blood drug concentration is determined by an LC-MS/MS method.
A non-compartmental model in Pharsight Phoenix 7.0 is used to calculate pharmacokinetic parameters. The specific results are shown in 5 the table below.
