Description

Anti-tumor compound used as VEGFR inhibitor and application thereof
Technical Field
The invention relates to a compound with VEGFR (vascular endothelial growth factor receptor) inhibitory activity, a pharmaceutically acceptable salt or a pharmaceutical composition containing the compound as an active substance, and a preparation method and application of the compound, and belongs to the technical field of medicines.
Background
Protein kinases are closely related to the pathogenesis of a plurality of diseases such as tumors, inflammations, autoimmune diseases, neurological diseases and the like, and the kinases are widely researched as a potential target in nearly 30 years. VEGFR is receptor tyrosine kinase transmembrane protein of VEGF (vascular epidermal growth factor), consists of 7 extracellular immunity protein domains, a transmembrane domain and an intracellular tyrosine kinase binding domain 3 part, and has VEGFR-1 (FLT-1), VEGFR2 (KDR) and VEGFR3 (FLT-4) e3 subtypes. After being combined with VEGF, VEGFR firstly undergoes dimerization and then autophosphorylation, so that a downstream signal path is activated and the generation of vascular endothelial cells is promoted. VEGFR expression will be higher because of the massive proliferation of tumor cells requiring new blood vessels to supply nutrients and metabolism. It is combined with receptor to induce tumor angiogenesis, can promote tumor growth, and participate in tumor metastasis and drug resistance mechanism formation. The occurrence and development of solid tumors depend on a large number of new blood vessels to deliver sufficient nutrients, and abnormal increase of VEGFR expression level is found in various solid tumor tissues such as gastric cancer, colon cancer, rectal cancer, ovarian cancer, breast cancer and the like. Blocking the VEGF/NEGFR signaling pathway has therefore become a viable approach in tumor therapy.
At present, the design idea of the medicine related to the VEGFR target point is based on the aim of finally treating by inhibiting angiogenesis around tumor cells, changing the microenvironment for tumor growth, and reducing the nutrition acquisition of the tumor cells. Until now, NMPA in china has approved 11 small molecule kinase inhibitor drugs on the market, wherein 4 VEGFR target drugs are apatinib (advanced gastric cancer), aniotinib (locally advanced or metastatic non-small cell lung cancer), furoquintinib (metastatic colorectal cancer), and fulvestrant (non-pancreatic neuroendocrine tumor); VEGFR targets are implicated in 11 of the currently approved marketed drugs by FDA, respectively, midastin (acute myelogenous leukemia, mast cell leukemia), lentivatinib (differentiated thyroid cancer), nintedanib (idiopathic pulmonary fibrosis), axitinib (renal cell carcinoma), regorafenib (colorectal cancer, lung cell cancer, gastrointestinal stromal tumor), cabozantinib (renal cell carcinoma, lung cell cancer, medullary thyroid cancer), ponatinib (chronic myelogenous leukemia, acute lymphocytic leukemia), vandetanib (thyroid cancer), pazopanib (renal cell carcinoma, soft tissue sarcoma), sunitinib (renal cell carcinoma, gastrointestinal stromal tumor, pancreatic neuroendocrine tumor) and sorafenib (thyroid cancer, renal cell carcinoma). The drug resistance, the toxic and side effects and the bioavailability are not high enough to be a great obstacle on the clinical application way of the medicine taking VEGFR as the target point, so that the development of a new medicine which is different from the chemical structure of the existing marketed medicine, takes VEGFR as the target point, has clinical drug resistance and substitution and has small toxic and side effects is an urgent need in the field of treatment of malignant tumors at present.
