Deregulation of Wnt/beta-catenin pathway is closely related to the pathogenesis of neurodegenerative diseases such as Alzheimer's disease (AD), and glycogen synthase kinase 3 beta (GSK-3 beta), the central negative regulator of Wnt pathway, is regarded as an important target for these diseases. Here, we report a series of benzo[e]isoindole-1,3-dione derivatives as selective GSK-3 beta inhibitors by rational-design and synthesis, which show high selectivity against GSK-3 beta over Cyclin-dependent kinase 2 (CDK2), and significantly activate the cellular Wnt/beta-catenin pathway. The structure-activity relationship of these GSK-3 beta inhibitors was also explored by in silico molecular docking. (C) 2015 Elsevier Inc. All rights reserved.

SAR exploration of the central diamine, benzyl, and terminal aminoalkoxy regions of the N-cyclic azaalkyl benzamide series led to the identification of very potent human urotensin-II receptorantagonists such as 1a with a K(i) of 4 nM. The synthesis and structure-activity relationships (SAR) of N-cyclic azaalkyl benzamides are described.
