Click approach to the discovery of 1,2,3-triazolylsalicylamides as potent Aurora kinase inhibitors

초록

A series of 1,2,3-triazolylsalicylamide derivatives has been developed from the antiproliferative agent 7 and was evaluated for their Aurora kinase inhibitory activity. The novel 1,2,3-triazolylsalicylamide scaffold could be readily assembled by Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition, allowing rapid access to the structurally diverse analogues. The synthesized 1,2,3-triazolylsalicylamide derivatives revealed a significant Aurora kinase inhibitory activity. In particular, 8g inhibited Aurora A with IC50 values of 0.37 mu M. The critical role of phenolic -OH in the binding was confirmed by a molecular modeling study. (C) 2014 Elsevier Ltd. All rights reserved.
