Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a substituted tetrahydronaphthalene amide compound which inhibits the growth of tumor cells and exhibits an antitumor effect, a pharmaceutically acceptable salt thereof, a preparation method and an application thereof. Background technique [0002] Imatinib competitively inhibits the binding site between adenosine triphosphate (ATP) and thymidine kinase (TK) receptors such as KIT, blocks TK phosphorylation, thereby inhibiting signal transduction, and can inhibit KIT mutations related to kinase activity (causing KIT receptor activation) and wild-type KIT. There are three main targets: Abelson (ABL) protein, KIT protein and platelet-derived growth factor (PDGF) receptor. Imatinib reduces kinase phosphorylation in a GIST-derived cell line (GIST882) through gain-of-function KIT mutations that cause stem cell factor-independent activation, and completely inhibits kinase phosphoryl...
