Design, synthesis and evaluation of 1,2,3-triazole derivatives as indoleamine 2,3-dioxygenase1 (IDO1) inhibitors
Abstract:Objective: A series of 1,2,3-triazole derivatives were designed and evaluated as inhibitors of indoleamine 2,3-dioxygenase1 (IDO1). Methods: Employing isosteric principle in medicinal chemistry, a total number of 28 1,2,3-triazole derivatives were synthesized from click chemistry,the inhibitory activity of these compounds were evaluated using reportedenzymatic assay method. Results: Among all these 28 1,2,3-triazoles derivatives, three of them: A11 A19 A24 displayed higher than 50% IDO1 inhibitory activity at 20μM.
Keywords: 1,2,3-triazole derivatives indoleamine 2,3-dioxygenase1 IDO1 inhibitors
