Description

A class of indazole derivative prodrugs, their preparation methods and uses Technical Field

[0001] This invention relates to a class of indazole derivative prodrugs, pharmaceutical compositions containing the prodrugs, synthetic methods for preparing the prodrugs and intermediates, and the use of the prodrugs and compositions in treating diseases caused by FGFR mutations, such as cancer. Background Technology

[0002] Fibroblast growth factor receptors (FGFRs) are a subfamily of tyrosine kinase receptors, comprising four isoforms: FGFR1, FGFR2, FGFR3, and FGFR4. Each FGFR consists of three distinct domains: an extracellular ligand-binding domain, a single-channel transmembrane domain, and an intracellular TK domain. Upon binding to fibroblast growth factor ligands (FGF), activated FGFRs phosphorylate several downstream signaling proteins, including PI3K-AKT, RAS-MAPK, and STAT. Therefore, FGFRs play crucial roles in numerous intracellular processes, including development, differentiation, survival, migration, and angiogenesis.

[0003] However, FGFR is susceptible to various somatic aberrations, resulting in common mutations such as overexpression, point mutations, and gene translocations, which can lead to carcinogenesis. FGFR overexpression caused by gene amplification, mutations in the FGFR EC region (extracellular domain) / TK region (kinase domain), and FGFR fusion can all cause FGFR signal dysregulation, thereby promoting the proliferation, survival, invasion, metastasis, and development of drug resistance of tumor cells, as well as the occurrence of tumor microenvironment (TME) angiogenesis and immune evasion [4]. FGFR aberrations account for about 7.1% of all solid tumor patients. The cancers most commonly affected by FGFR aberrations are urothelial carcinoma (32%), liver cancer (30%), cholangiocarcinoma (25%), breast cancer (18%), and gastric cancer (7%).

[0004] FGFR inhibitors inhibit tumor growth by blocking FGFR-mediated signaling pathways, making them a new option for targeted cancer therapy. Although many FGFR inhibitor compounds exhibit good biological activity and in vivo efficacy, in some cases it may be necessary to adjust their solubility or other properties to optimize their bioavailability. Summary of the Invention

[0005] This invention discloses novel prodrugs of a class of indazole derivatives, compositions containing the prodrugs, and their therapeutic uses, particularly as FGFR inhibitors. In some embodiments, the prodrugs are used to improve the solubility and oral bioavailability of the drug. In other embodiments, this invention relates to methods for preparing the prodrugs.

[0379] Experiment on the inhibitory activity of the compound on the proliferation of RT-112 (bladder cancer cells) cells

[0380] This experiment uses The Luminescent Cell Viability Assay (Promega: G7573) kit is a homogenization method for detecting cell viability by quantifying ATP to determine the viability of cultured cells.

[0381] ①RT112 cells were cultured at 37℃ and 5% CO2 in MEM complete medium (Gibco: 51200038) (10% FBS (Gibco: 10091-148) + 1% Pen Strep (Gibco: 15140122) + 1% NEAA (Gibco: 11140050)).

[0382] ② Harvest cells in the logarithmic growth phase and count them using a platelet counter. Assess cell viability using the trypan blue rejection assay to ensure it is above 90%.

[0383] ③ Adjust the cell density using MEM complete medium, and then seed 90 μL of the medium into 96-well cell culture plates, for a total of 3000 cells.

[0384] ④ Incubate the cells in the 96-well plate at 37°C and 5% CO2 for 24 hours.

[0385] ⑤ After 24 hours, prepare a 10-fold drug solution with an initial maximum drug concentration of 10 μM. Dilute the drug 10 times and 4 times. Then transfer 10 μL of each serially diluted compound to the corresponding well of the 96-well cell plate. Set up two replicates for each drug concentration.

[0386] ⑥ The cells in the 96-well plate with the added drug were cultured at 37°C and 5% CO2 for 72 hours, and then CTG analysis was performed.

[0387] ⑦ Melt the CTG reagent and equilibrate the cell plate to room temperature for 30 minutes.

[0388] ⑧ Add 50 μL of CTG solution to each well.

[0389] ⑨ Vibrate on a fixed-track shaking table for 5 minutes to cause cell lysis.

[0390] ⑩ Place the cell plate at room temperature for 20 minutes to stabilize the cold light signal. Read the cold light value and collect the data.

[0391] The data was analyzed using the XLFit Excel plugin version 5.5.0.5. A nonlinear S-curve regression was used to fit the data to derive the dose-response curve, and the IC was calculated from this curve. 50 value.
