Abstract

Licochalcone B (LCB), an extract from the root of Glycyrrhiza inflate, has the same caffeic acid scaffold as curcumin (Cur), which is known as an anti-Alzheimer’s disease (AD) agent. However, there is no relevant research about anti-AD activity of LCB. In this study, the anti-AD activity of LCB was investigated. LCB could inhibit amyloid beta (Aβ42) self-aggregation (IC50 = 2.16 ± 0.24 μM) and disaggregate pre-formed Aβ42 fibrils, reduce metal-induced Aβ42 aggregation through chelating metal ions. Molecular docking further revealed that LCB inhibited Aβ42 self-aggregation through forming two hydrogen bonds with Lys28 to block the salt bridge interaction at the C-terminus of Aβ42. Anti-oxidant property of LCB was also observed by DCFH-DA assay. In addition, LCB did show neuroprotective activity against H2O2-induced cell death in SH-SY5Y cells. In general, our results demonstrate that LCB, as a multifunctional agent, is likely to be promising therapeutics for AD.

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.
