Definitions
- the present invention relates to a salt form, a crystal form and a preparation method of a class of tricyclic compounds containing a pyrimidine group.
- Receptor tyrosine kinase c-Met also known as hypatocyte growth factor (HGF) receptor, is a transmembrane receptor with autophosphorylation activity encoded by the MET gene.
- HGF hypatocyte growth factor
- RTKs Receptor tyrosine kinases
- c-Met occurs in many tumor cells, such as hepatocellular carcinoma, gastric cancer, ovarian cancer, non-small cell lung cancer, renal cancer and other cancer cells. Overexpression is closely related to the formation and prognosis of various tumors. Excessive activation of the HGF/c-Met pathway will lead to the activation of downstream signaling pathways, thereby inducing cancer. In addition, the overexpression of HGF and c-Met can also lead to resistance responses of EGFR, RAS-RAF-MEK and Akt-mTOR signaling pathways to related inhibitors, which are important mechanisms of tumor cell escape.
- HGF hypoxia-regulated endothelial growth factor
- c-Met phosphorylation of c-Met
- PI3K-Akt pathway activates the downstream PI3K-Akt pathway
- upregulation and secretion of HGF in the tumor microenvironment can lead to resistance of cells to RAS inhibitors.
- tumor cells After blocking the abnormally activated HGF/c-Met signaling pathway in tumor cells, tumor cells will undergo a series of changes such as cell morphological changes, slowed proliferation, reduced tumorigenicity, and reduced invasive ability. Therefore, the development of a highly active c-Met inhibitor can provide an effective treatment method for a variety of primary c-Met signaling pathway abnormalities and drug-resistant c-Met abnormal expression tumors.
- the intervention therapies for the c-Met pathway mainly include the following: (1) Therapeutic antibodies: bind to HGF or c-Met and inhibit the c-Met pathway by interfering with the interaction between HGF and c-Met; (2) Small molecule tyrosine Kinase inhibitors: inhibit c-Met kinase activity or other kinases that play an important role in cancer progression; 3 HS90 inhibitor-like molecules: block the c-Met pathway by affecting the stability or expression of c-Met protein; 4 Functional molecules that interfere with downstream effectors of the c-Met pathway.
- the c-Met small molecule inhibitors currently under clinical research mainly include Crizotinib, Tepotinib (EMD1214063), Capmatinib, Volitinib, Cabozantinib (XL-184) and ARQ-197. Although these drugs have shown good clinical effects, some of them suffer from high molecular clinical doses, large clinical side effects, and low drug stability. Therefore, the development of novel c-Met inhibitors with high activity, high selectivity and good drug-like properties is still an unmet clinical need.
