Description

technical field [0001] The present invention relates to the field of compounds, in particular to a class of compounds targeting FAK (Focal Adhesion Kinase) and its F-18 marker, as well as their preparation methods and applications. Background technique [0002] Tumor is one of the major diseases that endanger human health and life, and the early diagnosis and individualized treatment of tumor have become an important focus of radiopharmaceutical research. Focal Adhesion Kinase (FAK) is involved in many aspects of tumorigenesis and development, and participates in various biological behaviors such as tumor cell adhesion, invasion, migration, proliferation and apoptosis. FAK is overexpressed in almost all tumor cells, so the expression level of FAK can be used as an indicator for early diagnosis, treatment and prognosis evaluation of tumors, and is an important target for tumor diagnosis and treatment. [0003] People have developed a variety of small molecule FAK inhibitors,...
