Discovery of γ-secretase modulators with a novel activity profile by text-based virtual screening.
2012
We present an integrated approach to identify and optimize a novel class of γ-secretase modulators (GSMs) with a unique pharmacological profile. Our strategy included (i) virtual screening through application of a recently developed protocol (PhAST), (ii) synthetic chemistry to discover structure–activity relationships, and (iii) detailed in vitro pharmacological characterization. GSMs are promising agents for treatment or prevention of Alzheimer’s disease. They modulate the γ-secretase product spectrum (i.e., amyloid-β (Aβ) peptides of different length) and induce a shift from toxic Aβ42 to shorter Aβ species such as Aβ38 with no or minimal effect on the overall rate of γ-secretase cleavag…
Selective Modulation of Aβ42 Production in Alzheimers Disease: Non-Steroidal Anti-Inflammatory Drugs and Beyond
2006
The amyloid-β (Aβ) peptides and in particular the longer, highly amyloidogenic isoform Aβ42 are believed by many to be the central disease-causing agents in Alzheimers disease (AD). Consequently, academic and pharmaceutical laboratories have focused on elucidating the mechanisms of Aβ production and developing strategies to diminish Aβ formation for treatment or prevention of AD. The most substantial advances have been made with respect to inhibitors of the γ-secretase enzyme, which catalyzes the final step in the generation of Aβ from the amyloid precursor protein (APP). Highly potent γ-secretase inhibitors which suppress production of all Aβ peptides are available today. However, due to t…
