- Abstract
- A strong relationship between abnormal functions of Aurora kinases and tumorigenesis has been reported for decades. Consequently, Aurora kinases serve as potential targets for anticancer agents. Here, we identified aminobenzothiazole derivatives as novel inhibitors of Aurora B kinase through bioisosteric replacement of the previous inhibitors, aminobenzoxazole derivatives. Most of the urea linked aminobenzothiazole derivatives showed potent and selective inhibitory activity against Aurora B kinase over Aurora A kinase. Molecular modeling indicated that compound 15g bound well to the active site of Aurora B kinase and formed the essential hydrogen bonds. The potent compounds, 15g and 15k, were selected, and their biological effects were evaluated using HeLa cell lines. It was found that these compounds inhibited the phosphorylation of histone H3 at Ser10 and induced G(2)/M cell cycle arrest. We suggest that the reported compounds have the potential to be further developed as anticancer therapeutics. (C) 2017 Elsevier Ltd. All rights reserved.
