The ASK1 inhibitor and the derivative thereof have an efficient inhibition effect on ASK1 kinase, and can be used for preparing drugsfor ASK1 kinase related diseases, the prepared drugs can play a drug effect at a molecular level and a cellular level, the application is wide, and the synthesis method of the compound is simple, convenient and easy to operate.

Description

technical field [0001] The present invention relates to an ASK1 inhibitor and its derivatives, preparation method, pharmaceutical composition and application, in particular to an ASK1 inhibitor which can be prepared as an ASK1 inhibitor drug and its derivatives, preparation method, pharmaceutical composition and application . Background technique [0002] Apoptosis signal-regulated kinase 1 (ASK1) belongs to the mitogen-activated protein kinase (MAPK) family, and the MAPK signaling pathway is one of the important signal transduction systems in organisms, involved in mediating cell proliferation, differentiation, apoptosis, and inflammation Physiological processes such as reactions. The MAPK family includes three subfamilies of extracellular signal-regulated kinase (ERK), p38MAPK and JNK. The MAPK family includes three levels of kinases. First, mitogen-activated protein kinase (MAP3K) is activated by intracellular and extracellular stimuli. The activated MAP3K phosphorylate...
