Abstract

Considering the importance of PDE4D inhibition and the modulation of biometals in Alzheimer's disease (AD) therapeutics, we have designed, synthesized and evaluated a series of new clioquinol-rolipram/roflumilast hybrids as multitarget-directed ligands for the treatment of AD. In vitro studies demonstrated that some of the molecules processed remarkable inhibitory activity against phosphodiesterase 4D (PDE4D), strong intracellular antioxidant capacity, potent inhibition of metal-induced aggregation of Aβ, and potential blood-brain barrier permeability. Compound 7a demonstrated significant improvement in cognitive and spatial memory in an Aβ 25-35-induce mouse model in Morris water-maze test (MWM). These results indicate that compound 7a is a promising multifunctional candidate that is worthy of further study.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PDE4 inhibitors include roflumilast, an oral small compound that selectively inhibits PDE4, an enzyme involved in controlling cAMP levels, and may lessen inflammation and increase neuronal survival.

    “PDE4 inhibitors, which are oral small compounds that selectively inhibit PDE4, an enzyme involved in controlling cAMP levels, include roflumilast (15, Figure 5), which may lessen inflammation and increase neuronal survival [177,178,179,180].”

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.
