Abstract

The invention belongs to the field of pharmaceutical chemistry and relates to a 1, 2, 3-triazole compound, comprising 4-(2-bromophenyl)-1H-1, 2, 3-triazole and 4-(2-chlorphenyl)-1H-1, 2, 3-triazole. The result of an inhibitory activity test of indoleamine 2, 3-dioxygenase indicates that the disclosed 1, 2, 3-triazole compound used as the indoleamine 2, 3-dioxygenase inhibitor has broad prospect of application and can be applied to the treatment of diseases with indoleamine 2, 3-dioxygenase-mediated tryptophan metabolic pathway pathological characteristics, including cancer, AIDS (Acquired Immure Deficiency Syndrome), Alzheimer disease, tristimania, cataract and other critical diseases.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry and relates to 1,2,3-triazole compounds and their application in medicine. Specifically related to 1,2,3-triazole compounds and their use in the preparation of indoleamine 2,3-dioxygenase inhibitors Background technique [0002] Indoleamine 2,3-dioxygenase (Indoleamine 2,3-dioxygenase, IDO) is an enzyme containing heme in cells, and it is the only one outside the liver that can catalyze the metabolism of tryptophan to make it along the path of kynurenine The rate-limiting enzyme of the acid pathway breaks down to a series of metabolites including quinolinic acid (MacKenzie, C.R.Et.al. Current Drug Metabolism, 2007, 8:237-244.). [0003] IDO is related to many physiological and pathological processes. Studies on pregnant mouse models have found that syncytiotrophoblast cells and antigen-presenting cells at the maternal-fetal interface can synthesize IDO and that the dynamic changes in IDO expre...
