Ma T, Chen P, Dong H, Wang X. Identification of key anti-neuroinflammatory components in Gastrodiae Rhizoma based on spectrum-effect relationships and its mechanism exploration. J Pharm Biomed Anal 2024; 248:116266. [PMID: 38879950 DOI: 10.1016/j.jpba.2024.116266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 05/17/2024] [Accepted: 05/28/2024] [Indexed: 06/18/2024]
Abstract
Gastrodiae Rhizoma was proven to have anti-inflammatory activity based on its main component of 4-hydroxybenzyl alcohol (4-HBA) and gastrodin (GAS). However, the anti-inflammatory activity of other phenols has been less reported. In this study, the n-BuOH extract was selected as the active anti-inflammatory part of Gastrodiae Rhizoma based on the LPS-induced inflammatory BV-2 cells. The spectral-effect relationship analysis of the n-BuOH extract showed the main effective components were GAS, 4-HBA, parishin A (PA), parishin B (PB), and parishin C (PC). Among them, PB could reduce LPS-induced expression of nitric oxide (NO), intracellular ROS, TNF-α, IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). Molecular docking predicted that PB had a good binding capacity to AMPKα and SIRT1 proteins of -12.1 kJ/mol and -7.6 kJ/mol, respectively. The Western Blot results further demonstrated that PB could inhibit NF-κB pathway by activating AMPK/SIRT1 pathway, thus exerting anti-LPS-induced neuroinflammatory effects. This study provides a referable idea for solving the problem of unclear action of TCM with complex compositions and is of great significance for the development of innovative medicines of traditional Chinese medicine.

Structural Characterization of Polysaccharide Derived from Gastrodia elata and Its Immunostimulatory Effect on RAW264.7 Cells. Molecules 2022; 27:molecules27228059. [PMID: 36432165 PMCID: PMC9694387 DOI: 10.3390/molecules27228059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 11/17/2022] [Accepted: 11/18/2022] [Indexed: 11/22/2022] Open
Abstract
A polysaccharide from Gastrodia elata (named GEP-1) was isolated with a DEAE-52 column and Sephadex G-100 column. The structural characteristics showed that GEP-1 was mainly composed of glucose (92.04%), galactose (4.79%) and arabinose (2.19%) with a molecular weight of 76.444 kDa. The polydispersity (Mw/Mn) of GEP-1 was 1.25, indicating that the distribution of molar mass (Mw) was relatively narrow, which suggested that GEP-1 was a homogeneous polysaccharide. Moreover, the molecular conformation plot of the root mean square (RMS) radius (<rg2> 1/2) versus Mw yielded a line with a slope less than 0.33 (0.15 ± 0.02), displaying that GEP-1 is a compact and curly spherical molecule in NaNO3 aqueous solution. NMR and methylation analyses revealed that the main chain structure of GEP-1 was α-(1→4)-glucans. Furthermore, it was proven that GEP-1 possessed cytoproliferative and enhancing phagocytic activities and induced cytokine (TNF-α, IL1-β) and nitric oxide (NO) release in macrophages by upregulating the related gene expression. In addition, the RNA-seq results suggested that the GEP-1-induced immunomodulatory effect was mainly caused by activation of the NF-κB signaling pathway, which was further verified by NF-κB ELISA and pathway inhibition assays. As a result, GEP-1 exhibits the potential to be developed as a novel cheap immunostimulant without obvious toxicity.

Abstract
A novel homogeneous polysaccharide named GEP-1 was isolated and purified from Gastrodia elata (G. elata) by hot-water extraction, ethanol precipitation, and membrane separator. GEP-1, which has a molecular weight of 20.1 kDa, contains a polysaccharide framework comprised of only glucose. Methylation and NMR analysis showed that GEP-1 contained 1,3,6-linked-α-Glcp, 1,4-linked-α-Glcp, 1,4-linked-β-Glcp and 1,4,6-linked-α-Glcp. Interestingly, GEP-1 contained citric acid and repeating p-hydroxybenzyl alcohol as one branch. Furthermore, a bioactivity test showed that GEP-1 could significantly promote the growth of Akkermansia muciniphila (A. muciniphila) and Lacticaseibacillus paracasei (L.paracasei) strains. These results implied that GEP-1 might be useful for human by modulating gut microbiota.

Abstract
Two homogeneous polysaccharides, GEP-3 and GEP-4, were purified from Gastrodia elata, a precious traditional Chinese medicine. Their structural characteristics were obtained using HPGPC, PMP-HPLC, LC/MS, FT-IR, NMR, and SEM methods. GEP-3 was 1,4-glucan with molecular weight of 20 kDa. Interestingly, GEP-4 comprised of a backbone of →[4)-α-Glcp-(1]10→[4)-α-Glcp-(1→]5[6)-β-Glcp-(1]11→6)-α-Glcp-(3→ and two branches of β-Glcp and p-hydroxybenzyl alcohol citrate, with repeating p-hydroxybenzyl alcohol attached to the backbone chain at O-6 position of →4,6)-α-Glcp-(1→ and O-1 position of →3,6)-α-Glcp-(1→. GEP-4 is a novel polysaccharide obtained and characterized for the first time. Bioactivity test indicated that both of them significantly promote the growth of Akkermansia muciniphila (Akk. muciniphila). Furthermore, GEP-3 and GEP-4 promoted the growth of Akk. muciniphila from high-fat diet (HFD) fecal microbiota. These results indicated that GEP-3 and GEP-4 were potential Akk. muciniphila growth promoters.

Glutathione peroxidase-1 knockout potentiates behavioral sensitization induced by cocaine in mice via σ-1 receptor-mediated ERK signaling: A comparison with the case of glutathione peroxidase-1 overexpressing transgenic mice. Brain Res Bull 2020; 164:107-120. [PMID: 32822804 DOI: 10.1016/j.brainresbull.2020.08.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 08/01/2020] [Accepted: 08/11/2020] [Indexed: 02/07/2023]
Abstract
We demonstrated that the gene of glutathione peroxidase-1 (GPx-1), a major antioxidant enzyme, is a potential protectant against the neurotoxicity and conditioned place preference induced by cocaine. Because the sigma (σ)-1 receptor is implicated in cocaine-induced drug dependence, we investigated whether the GPx-1 gene modulates the σ-1 receptor in the behavioral sensitization induced by cocaine. Cocaine-induced behavioral sensitization was more pronounced in GPx-1 knockout (KO) than wild-type (WT) mice and was less pronounced in GPx-1 overexpressing transgenic (GPx-1 TG) than non-TG mice. Cocaine treatment significantly enhanced the oxidative burden and reduced the GSH levels in the striatum of WT, GPx-1 KO, and non-TG mice but not in that of GPx-1 TG mice. In addition, cocaine significantly increased the nuclear translocation, its DNA binding activity of nuclear factor erythroid-2-related factor 2 (Nrf2) as well as the mRNA expression of γ-glutamylcysteine (GCL). The genetic depletion of GPx-1 inhibited the Nrf2-related glutathione system, whereas the genetic overexpression of GPx-1 activated this system against behavioral sensitization. BD1047, a σ-1 receptor antagonist, and U0126, an ERK inhibitor significantly induced the Nrf2-related antioxidant potential against behavioral sensitization. Unlike BD1047, U0126 did not affect the cocaine-induced σ-1 receptor immunoreactivity, suggesting that the σ-1 receptor is an upstream molecule for ERK signaling. Importantly, BD1047 and U0126 failed to affect the σ-1 receptor immunoreactivity and ERK phosphorylation induced by cocaine in GPx-1 TG mice. Our results suggest that GPx-1 is a critical mediator for the attenuation of cocaine-induced behavioral sensitization via modulating σ-1 receptor-mediated ERK activation by the induction of the Nrf2-related system.

Abstract
The aim of this study was to investigate whether the glutathione peroxidase-1 gene (GPx-1) affects cocaine-induced conditioned place preference (CPP) using a mouse model. Cocaine-induced CPP was accompanied by an increase in the level of σ-1 receptor in the nucleus accumbens (NAc). This phenomenon was more pronounced in the GPx-1 gene knockout (GPx-1 KO) than in wild type (WT) mice. In contrast, the CPP and expression of σ-1 receptor were much less pronounced in GPx-1-overexpressing transgenic (GPx-1 TG) mice than non-transgenic (non-TG) mice. Treatment of the mice with BD1047, a σ-1 receptor antagonist, significantly attenuated both cocaine-induced CPP and c-Fos-immunoreactivity (c-Fos-IR) in WT and GPx-1 KO mice, although the effects were more evident in the latter group. Despite the protective effects of BD1047 on cocaine-induced CPP and c-Fos in non-TG mice, there were no additional protective effects in cocaine-treated GPx-1 TG mice, indicating that the σ-1 receptor is a critical target for GPx-1-mediated psychoprotective activity. Overall, our results suggest that GPx-1 attenuates cocaine-induced CPP via inhibition of σ-1 receptor expression.

Abstract
BACKGROUND Gastrodia elata Blume (G. elata) is a traditional Chinese herb used for centuries in folk medicine. Due to the claimed anticonvulsant properties of G. elata, it is expected that this herb continues to be a target of research, aiming to deepen the available knowledge on its biological activity and safety. PURPOSE The current review aims to discuss the most recent advances on the elucidation of the phytochemical composition and anticonvulsant potential of G. elata. METHODS Available literature was reviewed from PubMed, ISI Web of Knowledge and Science Direct, using combinations of the following keywords: Gastrodia elata, tianma, epilepsy, anticonvulsant and pharmacokinetics. Abstracts and full texts were evaluated for their clarity and scientific merit. RESULTS G. elata rhizome, as well as specific phenolic compounds isolated from this herb, have demonstrated anticonvulsant potential in a variety of in vitro and in vivo models. The pharmacological mechanisms potentially involved in the anticonvulsant activity have been extensively studied, being similar to the known mechanisms claimed for the available antiepileptic drugs. In addition, the pharmacokinetics of the main bioactive component of G. elata (gastrodin) has also been studied. CONCLUSION Due to its recognised therapeutic properties, G. elata has gained an increasing interest within the scientific community and, therefore, new medicinal preparations containing G. elata rhizome itself or its bioactive components are expected to be developed in the coming years. Moreover, specific phytochemical constituents isolated from G. elata may also be considered to integrate programs of discovery and development of new anticonvulsant drug candidates.

Abstract
Preclinical research has indicated that females may be more sensitive to the rewarding properties of cocaine. However, the majority of this research has been done in rodent species. Environmental cues associated with human drug-taking behavior tend to be visual. Because rodents do not rely on the visual system as their primary sense modality, the use of a visually oriented species may add to our understanding of cue-elicited drug cravings and relapse. The present study examined the potential role of the steroid hormone, estradiol, in the rewarding properties of cocaine in female Japanese quail using a conditioned place preference (CPP) procedure. In the current experiment, female quail were housed on either an 8L:16D (light:dark) or 16L:8D (light:dark) cycle for 21 days to induce photoregression or photostimulation, respectively. They then received 10, 20, or 30 mg/kg cocaine, or saline during conditioning. Conditioning trials were carried out for 8 days, once per day for 30 min, for a total of 4 cocaine and 4 saline alternating conditioning trials. Results indicated that female quail housed in long-light conditions (16L:8D) had significantly higher levels of estradiol than short-cycle females. Additionally, photostimulated female quail developed a CPP to 10 and 20 mg/kg cocaine. Short-cycle females did not show cocaine-induced CPP to any dose tested. Results indicate that cocaine is dose-dependently rewarding to photostimulated female Japanese quail. Furthermore, the current findings suggest that estradiol may enhance the rewarding properties of cocaine in female quail. (PsycINFO Database Record

Abstract
Selegiline is a monoamine oxidase-B (MAO-B) inhibitor with anti-Parkinsonian effects, but it is metabolized to amphetamines. Since another MAO-B inhibitor N-Methyl, N-propynyl-2-phenylethylamine (MPPE) is not metabolized to amphetamines, we examined whether MPPE induces behavioral side effects and whether MPPE affects dopaminergic toxicity induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Multiple doses of MPPE (2.5 and 5 mg/kg/day) did not show any significant locomotor activity and conditioned place preference, whereas selegiline (2.5 and 5 mg/kg/day) significantly increased these behavioral side effects. Treatment with MPPE resulted in significant attenuations against decreases in mitochondrial complex I activity, mitochondrial Mn-SOD activity, and expression induced by MPTP in the striatum of mice. Consistently, MPPE significantly attenuated MPTP-induced oxidative stress and MPPE-mediated antioxidant activity appeared to be more pronounced in mitochondrial-fraction than in cytosolic-fraction. Because MPTP promoted mitochondrial p53 translocation and p53/Bcl-xL interaction, it was also examined whether mitochondrial p53 inhibitor pifithrin-μ attenuates MPTP neurotoxicity. MPPE, selegiline, or pifithrin-μ significantly attenuated mitochondrial p53/Bcl-xL interaction, impaired mitochondrial transmembrane potential, cytosolic cytochrome c release, and cleaved caspase-3 in wild-type mice. Subsequently, these compounds significantly ameliorated MPTP-induced motor impairments. Neuroprotective effects of MPPE appeared to be more prominent than those of selegiline. MPPE or selegiline did not show any additional protective effects against the attenuation by p53 gene knockout, suggesting that p53 gene is a critical target for these compounds. Our results suggest that MPPE possesses anti-Parkinsonian potentials with guaranteed behavioral safety and that the underlying mechanism of MPPE requires inhibition of mitochondrial oxidative stress, mitochondrial translocation of p53, and pro-apoptotic process.

Salgado PRR, da Fonsêca DV, Braga RM, de Melo CGF, Andrade LN, de Almeida RN, de Sousa DP. Comparative Anticonvulsant Study of Epoxycarvone Stereoisomers. Molecules 2015; 20:19660-73. [PMID: 26528962 PMCID: PMC6332048 DOI: 10.3390/molecules201119649] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2015] [Revised: 10/12/2015] [Accepted: 10/20/2015] [Indexed: 01/13/2023] Open
Abstract
Stereoisomers of the monoterpene epoxycarvone (EC), namely (+)-cis-EC, (-)-cis-EC, (+)-trans-EC, and (-)-trans-EC, were comparatively evaluated for anticonvulsant activity in specific methodologies. In the pentylenetetrazole (PTZ)-induced anticonvulsant test, all of the stereoisomers (at 300 mg/kg) increased the latency to seizure onset, and afforded 100% protection against the death of the animals. In the maximal electroshock-induced seizures (MES) test, prevention of tonic seizures was also verified for all of the isomers tested. However, the isomeric forms (+) and (-)-trans-EC showed 25% and 12.5% inhibition of convulsions, respectively. In the pilocarpine-induced seizures test, all stereoisomers demonstrated an anticonvulsant profile, yet the stereoisomers (+) and (-)-trans-EC (at 300 mg/kg) showed a more pronounced effect. A strychnine-induced anticonvulsant test was performed, and none of the stereoisomers significantly increased the latency to onset of convulsions; the stereoisomers probably do not act in this pathway. However, the stereoisomers (+)-cis-EC and (+)-trans-EC greatly increased the latency to death of the animals, thus presenting some protection. The four EC stereoisomers show promise for anticonvulsant activity, an effect emphasized in the isomers (+)-cis-EC, (+)-trans-EC, and (-)-trans-EC for certain parameters of the tested methodologies. These results serve as support for further research and development of antiepileptic drugs from monoterpenes.

Neuropharmacological Potential of Gastrodia elata Blume and Its Components. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:309261. [PMID: 26543487 PMCID: PMC4620291 DOI: 10.1155/2015/309261] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/21/2015] [Revised: 09/06/2015] [Accepted: 09/15/2015] [Indexed: 02/07/2023]
Abstract
Research has been conducted in various fields in an attempt to develop new therapeutic agents for incurable neurodegenerative diseases. Gastrodia elata Blume (GE), a traditional herbal medicine, has been used in neurological disorders as an anticonvulsant, analgesic, and sedative medication. Several neurodegenerative models are characterized by oxidative stress and inflammation in the brain, which lead to cell death via multiple extracellular and intracellular signaling pathways. The blockade of certain signaling cascades may represent a compensatory therapy for injured brain tissue. Antioxidative and anti-inflammatory compounds isolated from natural resources have been investigated, as have various synthetic chemicals. Specifically, GE rhizome extract and its components have been shown to protect neuronal cells and recover brain function in various preclinical brain injury models by inhibiting oxidative stress and inflammatory responses. The present review discusses the neuroprotective potential of GE and its components and the related mechanisms; we also provide possible preventive and therapeutic strategies for neurodegenerative disorders using herbal resources.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gastrodia elata (GE) Blume (family Orchidaceae) is a traditional Chinese herbal medicine for treating headaches, dizziness, tetanus, and epilepsy, indicating neuronal protective functions. AIM OF THE STUDY To evaluate the neuroprotection of GE and its molecular mechanism in preventing serum deprivation-induced PC12 cell apoptosis. MATERIALS AND METHODS An MTT assay and Hoechst staining were used to respectively validate serum deprivation-induced cell death and apoptosis. Cyclic (c)AMP formation and protein kinase (PK)A activity were also measured after GE treatment. Western blotting was used to detect the phosphorylation of the cAMP response element-binding (CREB) protein. Transient transfection of a dominant negative CREB was used to validate the importance of CREB. RESULTS GE targeted the adenosine A(2A) receptor (A(2A)-R). GE increased cAMP formation, PKA activity, and phosphorylation of the CREB protein. GE-induced CREB protein phosphorylation and protection was blocked by a PKA inhibitor and overexpression of the dominant negative CREB, respectively. CONCLUSIONS These results support the neuroprotective effects of GE. The protective mechanism might be mediated through an A(2A)-R/cAMP/PKA/CREB-dependent pathway.
