Abstract

The invention provides an azaindole compound with a structure shown as a formula (I) and application of the azaindole compound. The azaindole compound can effectively inhibit SMAD3-phosphorylation andhas good anti-tumor activity in a rat LCC induced tumor model. Compared with a compound SIS3, part of the azaindole compound provided by the invention is obviously improved in water solubility. The azaindole compound provided by the invention is expected to become an effective drug for preventing and treating tumors.

Description

technical field [0001] The invention relates to the technical field of medicinal chemistry, in particular to an azaindole compound and its application. Background technique [0002] Tumor growth and metastasis are the main causes of death in cancer patients. In the steps of tumor invasion and metastasis, transforming growth factor β (TGF-β) plays a tumor-promoting role. Due to the pleiotropic effects and complex functions of TGF-β, its inhibition may lead to side effects, while the downstream mediators of TGFβ signaling Because SMAD3 contains a DNA-binding domain, it can directly bind to the promoter in the target gene to regulate transcription, but SMAD2 and SMAD4 do not have these functions. In addition, SMAD3 has the ability to regulate the expression of key target proteins in tumor immunotherapy. For example, SMAD3 can up-regulate the expression of programmed death receptor 1 (PD-1) on T cells, but SMAD2 cannot up-regulate the expression of PD-1; target The silencing o...
