1.Gastrodin Attenuates Cognitive Deficits Induced by 3,3'-Iminodipropionitrile.

3,3'-Iminodipropionitrile (IDPN), one of the nitrile derivatives, can induce persistent neurotoxicity, and therefore cause dyskinesia and cognitive impairments. Gastrodin, a main bioactive ingredient of Gastrodia elata Blume, is shown to greatly improve cognitive function. The aim of this study was to further determine whether administration of gastrodin can ameliorate IDPN-induced cognitive deficits in the Morris water maze (MWM) and novel object recognition (NOR) task, and to explore the underlying mechanisms. Results showed that exposure to IDPN (100 mg/kg/day, for 8 days) significantly impaired spatial and object recognition memory and that repeated treatment with gastrodin (150 mg/kg/day, for 6 weeks) could effectively alleviate the IDPN-induced cognitive impairments as indicated by increased spatial memory and discrimination ratio in the MWM and NOR tests. Gastrodin treatment also reverted IDPN-induced decreases of γ-aminobutyric acid (GABA) levels and increases of a2 GABAA receptor protein expression in the prefrontal cortex and hippocampus of IDPN-treated rats.

Migraine is a highly prevalent neurovascular disorder in the brain. An optimal therapy for migraine has not yet been developed. Gastrodin (Gas), the main effective constitute from Gastrodiae Rhizoma (Tianma in Chinese), has been indicated for migraine treatment and prophylaxis more than 30years, with demonstrated safety. However, Gas is a phenolic glycoside, with relatively low concentrations and weak efficacy in the central nervous system. To develop more effective anti-migraine agents, we synthesized a novel Gas derivative (Gas-D). In the present study, comparative pharmacodynamic evaluations of Gas and Gas-D were performed in a model of nitroglycerin (NTG)-induced migraine in rats and the hot-plate test in mice. Following behavioral testing in this migraine model, external jugular vein blood and the trigeminal nucleus caudalis (TNC) were collected to analyze plasma nitric oxide (NO) and calcitonin gene-related peptide (CGRP) concentrations and c-Fos expression in the TNC.
3.Simultaneous Qualitative Assessment and Quantitative Analysis of Metabolites (Phenolics, Nucleosides and Amino Acids) from the Roots of Fresh Gastrodia elata Using UPLC-ESI-Triple Quadrupole Ion MS and ESI- Linear Ion Trap High-Resolution MS.
Chen S1, Liu JQ1, Xiao H1, Zhang J1, Liu A1. PLoS One. 2016 Mar 8;11(3):e0150647. doi: 10.1371/journal.pone.0150647. eCollection 2016.
A sensitive, effective and optimized method, based on ultra performance liquid chromatography (UPLC) coupled with ESI-triple quadrupole ion MS and ESI-linear ion trap high-resolution MS, has been developed for the simultaneous quantitative and qualitative determination of phenolics, nucleosides and amino acids in the roots of fresh Gastrodia elata. Optimization of the analytical method provided higher separation efficiency and better peak resolution for the targeted compounds. The simultaneous separation protocols were also optimized by routinely using accurate mass measurements, within 5 ppm error, for each molecular ion and the subsequent fragment ions. In total, 31 compounds, including 23 phenolics, two nucleosides, four amino acids, one gastrodin and one other compound were identified or tentatively characterized. Mono-substituted parishin glucoside (9), methoxy mono-substituted parishin (13), methyl parishin (26), p-hydroxybenzyl di-substituted parishin (29), and p-hydroxybenzyl parishin (31) were tentatively identified as new compounds.
4.Gastrodin suppresses BACE1 expression under oxidative stress condition via inhibition of the PKR/eIF2α pathway in Alzheimer's disease.
Zhang JS1, Zhou SF1, Wang Q1, Guo JN1, Liang HM1, Deng JB2, He WY3. Neuroscience. 2016 Jun 14;325:1-9. doi: 10.1016/j.neuroscience.2016.03.024. Epub 2016 Mar 14.
The expression of β-site APP-cleaving enzyme 1 (BACE1) is increased in the brain of late-onset sporadic Alzheimer's disease (AD) and oxidative stress may be the potential cause of this event. The phenolic glucoside gastrodin (Gas), a main component of a Chinese herbal medicine Gastrodia elata Blume, has been demonstrated to display antioxidant activity and suppresses BACE1 expression. However, the mechanisms by which Gas suppresses BACE1 expression are not clear. Morris water maze test was performed to assess the effect of Gas treatment on memory impairments in Tg2576 mice. The level of oxidative stress in the brain of Tg2576 mice was determined by measuring the superoxide dismutase (SOD) activity, catalase (CAT) activity, and the levels of malondialdehyde (MDA) and ROS. In vivo and in vitro, we detected the expression levels of BACE1, pPKRThr446, PKR, pPERKThr981, PERK, peIF2αSer51, and eIF2α using western blot analysis. We found that Gas improved learning and memory abilities of Tg2576 transgenic mice and attenuated intracellular oxidative stress in hippocampi of Tg2576 mice.
