Abstract

The invention relates to a 1,2,4-triazole compound shown as formula (I) and pharmaceutically acceptable salts thereof. The compound has the activities of apoptosis signal-regulating kinase 1 ('ASK1')inhibitors, so that the compound can be used for treating ASK1-induced symptoms, including chronic liver diseases, cardiovascular diseases, metabolic disturbance, respiratory system disorder, intestines and stomach disorder and neurodegenerative diseases. The invention also provides a drug compound containing the compound disclosed by the invention and an application thereof.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a 1,2,4-triazole compound, a composition containing the compound and its application. In particular, the present invention relates to certain deuterium-substituted 5-(4-cyclopropyl-1H-imidazol-1-yl)-2-fluoro-4-methyl-N-[6-(4-isopropyl- 4H-1,2,4,-triazol-3-yl)-2-pyridine]-benzamide, these deuterium-substituted compounds are used in the treatment of ASK1-mediated diseases, and have better pharmacokinetic properties . Background technique [0002] Many current drugs suffer from poor absorption, distribution, metabolism and / or excretion (ADME) properties, which prevent their wider use or limit their use to certain indications. Poor ADME properties are also an important reason for the failure of drug candidates in clinical trials. One such problem is rapid metabolism, which causes many drugs that would otherwise be highly effective in disease treatment to be cleared fr...
