NSAIDs and enantiomers of flurbiprofen target γ-secretase and lower Aβ42 in vivo

Open access

Abstract

Epidemiologic studies demonstrate that long-term use of NSAIDs is associated with a reduced risk for the development of Alzheimer disease (AD). In this study, 20 commonly used NSAIDs, dapsone, and enantiomers of flurbiprofen were analyzed for their ability to lower the level of the 42-amino-acid form of amyloid beta protein (Abeta42) in a human H4 cell line. Thirteen of the NSAIDs and the enantiomers of flurbiprofen were then tested in acute dosing studies in amyloid beta protein precursor (APP) transgenic mice, and plasma and brain levels of Abeta and the drug were evaluated. These studies show that (a). eight FDA-approved NSAIDs lower Abeta42 in vivo, (b). the ability of an NSAID to lower Abeta42 levels in cell culture is highly predicative of its in vivo activity, (c). in vivo Abeta42 lowering in mice occurs at drug levels achievable in humans, and (d). there is a significant correlation between Abeta42 lowering and levels of ibuprofen. Importantly, flurbiprofen and its enantiomers selectively lower Abeta42 levels in broken cell gamma-secretase assays, indicating that these compounds directly target the gamma-secretase complex that generates Abeta from APP. Of the compounds tested, meclofenamic acid, racemic flurbiprofen, and the purified R and S enantiomers of flurbiprofen lowered Abeta42 levels to the greatest extent. Because R-flurbiprofen reduces Abeta42 levels by targeting gamma-secretase and has reduced side effects related to inhibition of cyclooxygenase (COX), it is an excellent candidate for clinical testing as an Abeta42 lowering agent.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
