Design, Synthesis, and Biological Evaluation of New 5-HT<sub>4</sub> Receptor Agonists: Application as Amyloid Cascade Modulators and Potential Therapeutic Utility in Alzheimer’s Disease
based on the scaffold of ML10302, a highly specific and partial 5-HT4R agonist, were efficiently prepared by parallel supported synthesis and their binding affinities and agonist activities evaluated. Furthermore, we showed that, in vivo, the two best candidates exhibited neuroprotective activity by increasing the level of the soluble form of the amyloid precursor protein (sAPPα) in the cortex and hippocampus

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.

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.
