Abstract

BACKGROUND:
Due to complex pathogenesis of Alzheimer’s disease (AD), currently there is no effective disease-modifying treatment. Acetylcholinesterase (AChE) has introduced itself as an important target for AD therapy. Linarin as the representative active ingredient of flavonoid glycoside in Flos chrysanthemi indici has been found to have anti-acetylcholinesterase effect.
AIMS:
The present study intended to explore the potential effect of linarin for treatment of AD.
MAIN METHODS:
In this study, molecular docking simulation was used to evaluate whether linarin could dock with AChE and decipher the mechanism of linarin as an AChE inhibitor. After molecular docking simulation, AlCl3-induced Alzheimer’s disease zebrafish model was established. Effects of linarin on treating AD zebrafish dyskinesia and AChE inhibition were compared with donepezil (DPZ) which was used as a positive control drug.
KEY FINDINGS:
Molecular docking simulation showed that linarin plays a critical role in AChE inhibition by binding AChE active sites. The experiments illustrated that the dyskinesia recovery rate of AD zebrafish could be significantly improved by linarin. The dyskinesia recovery and AChE inhibition rate were 88.0% and 74.5% respectively, while those of DPZ were 79.3% and 43.6%.
SIGNIFICANCE:
These findings provide evidences for supporting linarin to be developed into an AD drug by inhibiting the activity of AChE.

Abstract

Acute lung injury (ALI) is an important cause of morbidity and mortality for critically ill patients, and linarin (LR) may be a potential treatment for ALI as it reportedly has antioxidant, anti‑inflammatory and apoptotic‑regulating activity. In the present study, the authors report that saline and LR (12.5, 25 and 50 mg/kg) were applied to male C57BL/6 mice via gavage. Then, mice were intratracheally injected with either saline or lipopolysaccharide (LPS). LR‑pretreatment attenuated LPS‑induced ALI and platelet activation and reduced CD41 expression levels and neutrophil platelet aggregates. Additionally, LPS‑triggered pulmonary myeloperoxidase activity and neutrophil infiltration in lung tissues, and this was eliminated by LR dose‑dependently. Furthermore, LPS‑induced oxidative stress and pro‑inflammatory cytokine release were downregulated by LR by inhibiting thioredoxin‑interacting protein and nuclear factor‑κB signaling pathways, including their downstream and upstream signals, such as xanthine oxidase, NLR family WHAT, pyrin domain‑containing 3 (NLRP3), apoptosis‑associated speck‑like protein containing a C‑terminal caspase recruitment domain (ASC), caspase‑1, IκB kinase‑α (IKK‑α) and IκBα. Moreover, in LPS‑induced mice, the mitogen‑activated protein kinase pathway was inactivated by LR. In vitro, LR reduced LPS‑induced inflammation and oxidative stress, which was linked to reduction of ROS. In conclusion, LR pretreatment may be protective against LPS‑induced ALI.

Abstract

OBJECTIVES:
As we all know, oxidative stress was one of the most important causes of ischemia-reperfusion injury. And it was reported that Nrf-2 as an important regulator for oxidative stress could be activated by Linarin. Thus it would be interesting to find whether Linarin could inhibit ischemia-reperfusion injury through activating Nrf-2.
METHODS:
In this study, cell activity was detected by MTT assay and caspase-3 activity detection kit. And the expressions or activities of some signal proteins were evaluated by western-blot or activity detection kits. At last, the effect and mechanism of Linarin on heart tissues were verified in the ischemia-reperfusion model of isolated hearts.
RESULTS:
The proliferation activity of cell was inhibited while the apoptosis rate was increased after hypoxia-reoxygenation. However, Linarin could inhibit these two variations. It was found that these effects of Linarin were related with the activation of Nrf-2 through PI3K/Akt signaling pathway. Meanwhile, the anti-oxidative enzymes, regulated by Nrf-2, were enhanced to against the oxidative stress caused by hypoxia-reoxygenation. And with the inhibition of oxidative stress, some proliferation and apoptosis related proteins such as NF-kB and Cytochrome C were adjusted to support the viability of cells. At last, these results were verified in the ischemia reperfusion experiment of isolated hearts.
CONCLUSIONS:
From this study, we assured that LIN could protect myocardial tissue from ischemia-reperfusion through activating Nrf-2.
