Abstract
Description
INDAZOLE COMPOUND AND PHARMACEUTICAL COMPOSITION, PREPARATION METHOD AND USE THEREOF
[0001] The present disclosure claims priority of the prior application with the application No. PCT / CN2024 / 075342, entitled “INDAZOLE COMPOUND AND PHARMACEUTICAL COMPOSITION, PREPARATION METHOD AND USE THEREOF” and filed before China National Intellectual Property Administration on Feb. 1, 2024; which is incorporated herein by reference in their entirety.TECHNICAL FIELD
[0002] The present disclosure belongs to the field of medicine, and particularly relates to an indazole compound, and pharmaceutical composition, preparation method and use thereof.BACKGROUND
[0003] Non-communicable diseases are the leading cause of death in the world, and cancer is the disease with the highest fatality rate among the non-communicable diseases, which brings a heavy burden to the social health and medical system. Traditional cancer treatment mainly includes surgery, radiotherapy, and chemotherapy, and chemotherapy is the main treatment for advanced cancer. Traditional chemical anti-cancer drugs have serious side effects due to poor targeting. With the emergence of targeted chemotherapeutic drugs typified by Gleevec, the pain caused by chemotherapy to patients has been alleviated. These targeted drugs are designed based on the different growth characteristics and expressed molecules of cancer cells compared with normal cells. For example, Gleevec specifically targets the constitutively activated tyrosine kinase in chronic myelogenous leukemia, thereby achieving a good therapeutic effect (Flynn and Gerriets, 2020) .
[0004] Receptor tyrosine kinases (RTKs) are high-affinity cell surface receptors for many polypeptide growth factors, cytokines and hormones. Of the 90 unique tyrosine kinase genes identified in the human genome, 58 encode receptor tyrosine kinase proteins. Mutations in the receptor tyrosine kinases activate a series of signaling cascade reactions that have many effects on protein expression. Receptor tyrosine kinases are a large family of proteins among tyrosine kinases, which are characterized by a hydrophobic transmembrane domain, and tyrosine kinases without a transmembrane domain are non-receptor tyrosine kinases. The main types of RTKs that have been discovered include: epidermal growth factor (EGF) receptor, platelet-derived growth factor (PDGF) receptor, macrophage colony stimulating factor (M-CSF) , insulin and insulin-like growth factor-1 (IGF-1) receptor, nerve growth factor (NGF) receptor, fibroblast growth factor (FGF) receptor, vascularendothelial growth factor (VEGF) receptor, hepatocyte growth factor (HGF) receptor, and the like. The receptor tyrosine kinases have not only been shown to be key regulators of normal cellular processes, but also play a key role in the development and progression of many types of cancer. Epidermal growth factor receptors are the most important and attractive targets of clinical and scientific interest in the treatment of most cancers. Drugs targeting receptor tyrosine kinases have been marketed, mainly including small molecule inhibitors and monoclonal antibodies.
[0005] Studies have shown that cancer patients are susceptible to developing acquired drug resistance during a one-year treatment cycle with receptor tyrosine kinases. Drug resistance includes pharmacological drug resistance and biological drug resistance, wherein the pharmacological drug resistance is mostly caused by the interaction of drugs in the body that prevents the drugs from reaching effective concentrations around cancer cells, but the cancer cells themselves may still be sensitive to the drugs; biological resistance is caused by the cancer heterogeneity, the generation of drug resistance mutations due to drug selection pressure, and the activation of alternative bypass signaling pathways.
[0006] Therefore, it is necessary to develop a new drug that has anti-cancer activity and can solve the pharmacological drug resistance and biological drug resistance of existing targeted drugs.SUMMARY

[0365] Bioactivity Example: Inhibitory Activity Test of Compounds on Cancer Cells
[0366] The inhibitory activity of apatinib (A) , the compounds disclosed herein, and combinations thereof on a gastric cancer cell line HGC-27 was tested by an MTT method as follows.
[0367] In this experiment, test compounds with different concentrations were separately used to act on the tumor cells described above for 48 h, and the tumor growth inhibition rate was detected by the MTT method, so that the degree of inhibition of the compounds on different tumor cells was detected.
[0368] Procedures:
[0369] A and the compounds disclosed herein were each dissolved in a certain volume of DMSO to prepare a mother liquor with a concentration of 20 mmol / L. The mother liquor was stored at -20 ℃, and when in use, the mother liquor was taken and diluted into a solution with a certain dilution factor.
[0370] The specific steps were as follows:
[0371] (1) The tumor cells described above in the logarithmic growth phase were taken, centrifuged, and resuspended, and the cell suspension density was adjusted to 4 × 104 cells / mL. The cell suspension was then added into a 96-well culture plate at 100 μL / well, and the cells were incubated in a cell incubator at 37 ℃ with 5%CO2 for conventional culture.
[0372] (2) After incubation for 24 h, the uniform growth of a single layer of adherent cells in each well was observed under a microscope. Monotherapy 071 preparation: A DMEM complete medium (containing 10%FBS and 1%anti-anti) was added into five 1.5 mL centrifuge tubes at 1 mL / tube, and 2.5 μL, 2 μL, 1.5 μL, 1 μL and 0.5 μL of 071 at a concentration of 20 mmol / L were added to the five tubes, respectively. Another four 1.5 mL centrifuge tubes were taken; 2 mL of the DMEM complete medium and 0.5 μL of 071 at a concentration of 20 mmol / L were added into the first tube, and the first tube was marked as 1; 1 mL of the DMEM complete medium was added into each of the remaining three tubes, and the three tubes were marked as 2, 3, and 4, respectively. 1 mL of drug mixture was taken from tube 1 and added into tube 2 for mixing, then 1 mL of the resulting drug mixture was taken from tube 2 and added into tube 3 for mixing, and subsequently, 1 mL of the resulting drug mixture was taken from tube 3 and added into tube 4 for mixing. 1 mL of the final drug mixture was then discarded. The drug mixtures at different concentrations were separately added into the wells of experimental groups at 160 μL / well. The final concentrations of 071 were 0.625 μmol / L, 1.25 μmol / L, 2.5 μmol / L, 5 μmol / L, 10 μmol / L, 20 μmol / L, 30 μmol / L, 40 μmol / L and 50 μmol / L, with 4 replicate wells set for each concentration. 071 + A preparation: All the samples were prepared according to the monotherapy 071 preparation, with each tube only containing 1 mL of drug mixture. 0.5 μL of A at a concentration of 20 mmol / L was added into each tube, and the final concentration of A was 10 μmol / L. Meanwhile, a blank group (only containing the culture medium without the addition of the cell suspension) and a negative control group (only containing the cell suspension) were set.
[0373] (3) The plate was incubated in an incubator for 48 h, and then the culture medium in the well plate was discarded. An MTT working solution was prepared as follows: 10 mL of a 1640 complete medium was mixed with 2 mL of MTT (5 mg / mL) according to 1640 complete medium: MTT (5 mg / mL, prepared with PBS) = 5: 1.120 μL of the MTT working solution was added into each well, and the plate was incubated for another 4 h in the incubator. The plate was then centrifuged at 3000 r for 3 min, and the upper culture medium was carefully discarded. 100 μL of DMSO was added into each well, and the absorbance OD value of each well was detected at a wavelength of 490 nm on an enzyme linked immunosorbent assay detector (shaking for 10 s before detection to fully dissolve the crystals) .
[0374] (4) The inhibitory effect of the samples on the cells was calculated by the following formula:
[0375] Inhibition rate (%) = (OD value of cell control well -OD value of administration well) / (OD value of cell control well -OD value of blank well) × 100%
[0376] Based on the calculated inhibition rates, the half maximal inhibitory concentration (IC50) values of the test compounds in the inhibition of cell growth were determined, as shown in the following table.
