Abstract

The invention relates to a heterocyclic compound, a pharmaceutical composition containing the same, a preparation method of the same, and an application of the heterocyclic compound as a fibroblast growth factor receptor (FGFR) inhibitor. The inhibitor is a heterocyclic compound as shown in a formula I which is described in the specification, or pharmaceutically acceptable salts, prodrugs, solventcompounds, polymorphs, isomers, stable isotope derivatives thereof, or pharmaceutical compositions containing the same. The compounds provided by the invention can be used for treatment or preventment of related diseases mediated by FGFR, such as cancers.

Description

technical field [0001] The invention relates to a preparation method of a class of heterocyclic compounds and pharmaceutical compositions containing them, and their use as inhibitors of fibroblast growth factor-associated receptor FGFR. The compounds involved in the present invention can be used to treat or prevent related diseases mediated by FGFR, such as cancer. Background technique [0002] Fibroblast Growth Factor Receptor (FGFR, Fibroblast Growth Factors Receptor) belongs to receptor-type protein tyrosine kinases, and this family mainly includes four members: FGFR1, FGFR2, FGFR3 and FGFR4. FGFR is involved in the regulation of cell proliferation, apoptosis, migration, angiogenesis and many other processes. Because of their broad range of roles, FGFRs and other RTKs are normally tightly regulated. In tumors, such as liver cancer, bladder cancer, lung cancer, breast cancer, prostate cancer, etc., FGFR activating mutations or ligand / receptor overexpression lead to its c...
