Definitions
- the invention belongs to the technical field of organic synthetic drugs, in particular to pyrazolopyrimidine derivatives, a preparation method thereof and the use thereof in the preparation of medicaments, and the pyrazolopyrimidine derivatives are mainly substituted at the 4-position.
- kinases are widely found in organisms and play a crucial role in regulating cell proliferation, growth, differentiation, apoptosis, and aging. Abnormal kinase activity can lead to many major diseases including cancer, various autoimmune diseases (such as lupus erythematosus, rheumatoid arthritis, psoriasis, etc.), diabetes, inflammation, and the like. In view of this, kinases have become a hot spot in the current research as one of the most important therapeutic targets for diseases.
- VEGFR2 Vascular endothelial growth factor receptor 2
- PDGFR platelet derived growth factor receptor
- Fms-like tyrosine kinase 3 human FMS-like tyrosine kinase 3 is another receptor tyrosine kinase that plays an important role in the proliferation and differentiation of hematopoietic stem cells.
- AML acute myeloid leukemia
- FLT3 has been used as an important therapeutic target for the treatment of AML, and its inhibitors are considered to be the most promising molecular targeted drugs for the treatment of AML.
- a few FLT3 inhibitors such as SU-5416, PKC-412 and CEP-701 have entered clinical trials.
- the latest research has found that the clinical trial results of these compounds are not satisfactory.
- One of the main reasons is that these compounds have large toxic side effects, which limits the increase of drug dosage and thus affects the therapeutic effect. Therefore, the development of high-efficiency and low-toxic FLT3 inhibitors for AML treatment is of particular importance.
- FLT1 human FMS-like tyrosine kinase 1
- FLT4 human FMS-like tyrosine kinase 4
- BRAF BRAF serine/threonine protein kinase
- cRAF cRAF serine/threonine Acid protein kinase
- FGFR1 fibroblast growth factor receptor 1
- RET RET receptor tyrosine kinase
- SRC SRC tyrosine kinase
- EphA2 EphA2 tyrosine kinase
- EphB2 EphB2 cheese
- Acid kinases c-KIT, CDK1, (tyrosine protein kinase KIT) and the like are also importantly involved in the development of tumors.
- FLT3 is not only associated with acute myeloid leukemia, but recent studies have found that FLT3 is also associated with a variety of autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, psoriasis, multiple sclerosis, and immune inflammation. Related to diseases. FLT3 is highly expressed in the progenitor cells of dendritic cells (DC), and FLT3 ligands induce differentiation and maturation of DC cells. In addition, FLT3 also showed high expression in mature DC cells, indicating that the FLT3 signaling pathway plays an important role in maintaining normal DC cell function. DC cells are key players in the human immune system, DC Abnormal regulation of cells is an important cause of various autoimmune diseases.
- DC dendritic cells

- Drug treatment After 10 hours of zebrafish embryo fertilization (microscopic observation of zebrafish embryo development to bud stage), healthy embryos were randomly selected, added to 24-well plates, 10 zebrafish embryos per well, and the culture medium was absorbed. Add different concentrations of compound solution. The concentration of each compound was set to 10 iig/mL, 3 ug/mL, and 1 U g/mL, respectively. At the same time, a blank control was set, and no compound was added. It was then placed in a 28 ° C incubator for cultivation.
- Figure 6 reflects the angiogenesis of FLK1 transgenic zebrafish at concentrations of compounds 4a-6 and 4a-31 at g/mL.
- the results showed that 4a-6 and 4a-31 inhibited angiogenesis in zebrafish well compared with the control group.
- the results of this experiment show that most of the compounds prepared in the examples of the present invention have a good inhibitory activity on the neovascularization of the FLK1 transgenic zebrafish, and this result reflects that these compounds have a good inhibitory activity against VEGFR2.
- Example 97 Compound 4a-58 in vivo anti-leukemia tumor experiment
- the purpose of this experiment was to examine the in vivo antitumor effect of the inventive compounds.
- the in vivo antitumor activity of the inventive compound 4a-58 was tested using a NOD-SCID mouse subcutaneous human leukemia solid tumor model.
- the cell strain used was human acute myeloid leukemia cell line MV4-11.
- the anti-leukemia drug Quizartinib (AC220) was used as a positive control.
- IMDM fetal bovine serum, trypsin and the like were purchased from Gibco BRL (Invitrogen Corporation, USA), IMDM medium was purchased from ATCC (American Type Culture Collection), human leukemia cell line MV4-11 was purchased from ATCC, USA, NOD-SCID was small. The mouse was purchased from Beijing Huakang Biotechnology Co., Ltd., China.
- Compound 4a-58 10 mg/kg qd ; Positive control AC220: 3mg/kg qd;
- Positive control AC220 10mg/kg q.d.;
- Observation index The body weight, tumor long diameter and short diameter of the tumor were measured every 3 days, and the tumor volume (length X width 2 X 0.5) was calculated to observe whether there was diarrhea, convulsion, rash, and significant decrease in body weight.
- test compound 4a-58 had significant growth inhibition effect on the FLT3-ITD mutant human acute myeloid leukemia cell line MV4-11, even if the tumor volume was large, at a dose of 3 mg/kg or more per day. Tumor growth can be completely inhibited. No adverse effects such as weight loss, rash, diarrhea, etc. were observed in the mice during the administration, indicating that the test compound 4a-58 was very low in toxicity at the test dose.
- Example 98 Test of angiogenesis inhibitory activity of compound 4a-54 in transgenic zebrafish
- the purpose of this experiment was to examine the inhibitory activity of the inventive compounds against neovascularization in vivo by examining the inhibition of intercellular vascularization of the transgenic fluorescent zebrafish FLK1-GFP at a single concentration.
- the neovascularization activity of 4a-54 is expressed by the degree of inhibition of internode blood vessels in zebrafish.
- the zebrafish used in the laboratory is a vascular fluorescent transgenic zebrafish (FLK1: GFP) o
- FLK1 vascular fluorescent transgenic zebrafish
- the breeding and breeding of zebrafish is based on the Westerfield method.
- One day before the eggs were taken the male and female zebrafish were paired in a 1:1 ratio.
- the next day at a temperature of about 28 ° C and sufficient light, they naturally mate to lay eggs.
- Sufficient zebrafish embryos were collected, washed, placed in embryo culture medium, and placed in a 28 ° C incubator. Morphological and developmental criteria are used to assess survival at any time. Dead embryos are white and should be removed in time to prevent deterioration of water quality.
- Drug treatment 10h after zebrafish embryo fertilization (microscopic observation of zebrafish embryo development to bud stage), select healthy embryos into groups, add 24-well plates, 6 zebrafish embryos per well, and absorb the culture medium. Different concentrations of the compound solution were added, and a blank control was set at the same time, no compound was added, and then it was cultured in a 28 ° C incubator.
- Figure 8 reflects the angiogenesis of FLK1 transgenic zebrafish at a concentration of 5 ⁇ M of compound 4a-54.
- Compound 5a-54 at a concentration of 5 ⁇ M completely inhibited angiogenesis in zebrafish compared to the blank control group.
- the results of the experiments show that the compounds prepared in the examples of the present invention have a good inhibitory activity on the neovascularization of FLK1 transgenic zebrafish.
