A series of hinge-binder tethered 1,2,3-triazolylsalicylamide derivatives were designed, synthesized, and evaluated for the Aurora kinase inhibitory activities. The novel hinge-binder tethered 1,2,3-triazolylsalicylamide scaffold was effectively assembled by Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC). A variety of alkynes with hinge binders were used to search proper structures-binding relationship to the hinge region. The synthesized 1,2,3-triazolylsalicylamide derivatives showed significant Aurora kinase inhibitory activity. In particular, 8a inhibited Aurora A kinase with an IC50 value of 0.284 mu M, whereas 8m inhibited Aurora B kinase with an IC50 value of 0.364 mu M. (C) 2016 Elsevier Ltd. All rights reserved.
