Abstract

A series of genistein derivatives with carbon spacer-linked alkylbenzylamines were designed, synthesized and tested as multifunctional agents for the treatment of Alzheimer's disease (AD). The results showed that most of these compounds exhibited good acetylcholinesterase (AChE) inhibitory activity, with moderate-to-good anti-oxidative activity. Specifically, compounds 10b, 19d and 25d exhibited significant inhibition of β-amyloid (Aβ) aggregation and exhibited metal chelating properties. In particular, 25d inhibited: self-induced Aβ₁₋₄₂ aggregation, Cu(2+)-induced Aβ₁₋₄₂ aggregation, and human AChE-induced Aβ₁₋₄₀ aggregation by 35%, 77.8%, and 36.2%, respectively. Moreover, both kinetic analysis of AChE inhibition and the molecular modeling study suggested that 25d binds simultaneously to catalytic active site and peripheral anionic site of AChE. More importantly, compound 25d disassembled the well-structured Aβ fibrils generated by Cu(2+)-induced Aβ aggregation by 72.1%. Furthermore, the step-down passive avoidance test showed this compound significantly reversed scopolamine-induced memory deficit in mice. These results suggest that 25d may be a promising multifunctional agent for AD treatment.

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?

  • In diabetic mice, genistein and some derivatives improve cognitive dysfunction by inhibiting AChE and modulating Ca2+ homeostasis in cholinergic neurons.

    “in diabetic mice genistein (Pedersen et al., 1996; Wang et al., 2016), as well as some of its derivatives (Qiang et al., 2014), can improve cognitive dysfunction by inhibiting the activity of AChE and by the modulation of Ca2+ homeostasis in cholinergic neurons (Jhamandas et al., 2001)”

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.
