However, the action sites of these inhibitors are mainly concentrated in the ATP-binding pocket of the FAK kinase domain. They are ATP competitive inhibitors, which can only affect or block the function of the kinase domain, but cannot block the FAK-independent backbone function of FAK, and are easy to drug resistance

The compound has good degradation activity on focal adhesionkinase (FAK). The compound and the geometrical isomer thereof or the pharmaceuticallyacceptable salt, hydrate, solvate or prodrug thereof are represented by the general formula I, wherein Y, L, X, Z and R1 are shown in the claims and the specification.
Description
technical field [0001] The present invention relates to the field of biomedicine and drug synthesis, and relates to a class of compounds targeted to degrade focal adhesionkinase (FAK) proteins, as well as pharmaceutically acceptable salts, hydrates, solvates or prodrugs of the compounds, and their preparation methods and its use as a therapeutic agent, especially as a FAK degradation agent. Background technique [0002] Focal adhesionkinase (FAK) is an intracellular non-receptortyrosine kinase that belongs to the superfamily of tyrosineprotein kinases and was first discovered in 1992 by Schaller et al. The structure of FAK can be divided into four parts: the middle kinase catalytic domain, the amino-terminal FERM (4.1-ezrin-radixin-moesin) domain, the carboxy-terminal local adhesion targeting domain (focal adhesion targeting, FAT) and rich Proline-rich regions (PRRs). Among them, the kinase domain is mainly responsible for regulating the kinase activity of FAK, while t...
