Fatty acid synthase (FAS), an essential enzyme for de novo lipogenesis, has been implicated in a number of disease states, including obesity, dyslipidemia, and cancer. To identify small-molecule inhibitors of FAS, the authors developed a bead-based scintillation proximity assay (SPA) to detect the fatty acid products of FAS enzymatic activity. This… (More)
Synthesis and SAR studies of novel aryl triazoles as gamma secretase modulators (GSMs) are presented in this communication. Starting from our aryl triazole leads, optimization studies were continued and the series progressed towards novel amides and lactams. Triazole 57 was identified as the most potent analog in this series, displaying single-digit… (More)
A series of 3-aryl-4-hydroxyquinolin-2(1H)-ones with fatty acid synthase inhibitory activity was prepared. Starting from a derivative with an IC(50) = 1.4 microM, SAR studies led to compounds with more than 70-fold increase in potency (IC(50) < 20 nM).
The triazolyl amide γ-secretase modulators are potent alternatives to the cinnamyl amides that have entered the clinic for the treatment of Alzheimer's disease. Herein we build on the lead benzoazepinones described in our prior communication with imidazomethoxyarene moiety alternatives that offer opportunities to fine tune physical properties as well as… (More)
Synthesis and SAR studies of novel triazolobenzazepinones as gamma secretase modulators (GSMs) are presented in this communication. Starting from our azepinone leads, optimization studies toward improving central lowering of Aβ42 led to the discovery of novel benzo-fused azepinones. Several benzazepinones were profiled in vivo and found to lower brain Aβ42… (More)
