We previously disclosed tricylic, 6-carboxylic acid-bearing 4-quinolones as GSK-3 beta inhibitors. Herein we discuss the optimization of this series to yield a series of more potent 6-nitrile analogs with insignificant anti-microbial activity. Finally, kinase profiling indicated that members of this class were highly specific GSK-3 inhibitors. (C) 2011 Elsevier Ltd. All rights reserved.
