Abstract
Epilepsy is considered common neurological diseases that threaten the lives of millions of people all around the world. Since ancient times, different forms of medications have been used to treat this condition. Adverse events associated with treatments and the residence time of available drugs caused to search for safer and more efficient therapies and drugs remain one of the major areas of research interest for scientists. As one of the therapeutics with fewer side effects, plants and their essential oils can be considered replacements for existing treatments. Medicinal plants have proven to be an effective natural source of antiepileptic drugs; most of them have their mechanism of action by affecting GABA receptors in different paths. Cannabis indica and Cymbopogon winterianus are well-known plant species with antiepileptic activities. The current review presenting a list of plants with antiepileptic effects aims to pave the way for finding alternative drugs with fewer side effects for scientists.

Biofabrication of Titanium Dioxide Nanoparticles Catalyzed by Solanum surattense: Characterization and Evaluation of their Antiepileptic and Cytotoxic Activities. ACS OMEGA 2023; 8:16948-16955. [PMID: 37214675 PMCID: PMC10193536 DOI: 10.1021/acsomega.3c00858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 04/26/2023] [Indexed: 05/24/2023]
Abstract
The green synthesis of nanoparticles using plant extract is a new method that can be used in various biomedical applications. Therefore, the green approach was an aspect of ongoing research for the synthesis titanium dioxide nanoparticles (TiO2 NP) using the Solanum surattense aqueous plant extract, which acts as a stabilizing and reducing agent. The synthesis of TiO2 NPs was confirmed by energy dispersive X-ray (EDX), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and UV-visible spectroscopy (UV-vis) analyses. The excitation energy to synthesize TiO2 NPs was identified through the UV-vis spectrophotometric analysis at a wavelength of 244 nm. Further, the FT-IR spectroscopy visualized different biomolecules like OH, C=O, C-H, and C-O that were present in an aqueous extract of the plant and were responsible for the stabilization of TiO2 NPs. The crystallinity and phase purity of TiO2 NPs were illustrated by the sharp peaks of the XRD pattern. The spherical morphology with sizes ranging from 10 to 80 nm was examined using SEM images. The elemental composition of TiO2 NPs was revealed by the intensity and narrow widths of titanium and oxygen using EDX analysis. This report also explains the antiepileptic activity of TiO2 NPs in a maximal electroshock-induced epileptic (MESE) and pentylenetetrazol (PTZ) model. The synthesized TiO2 NPs showed maximum antiepileptic activity in the PTZ model, significantly decreasing the convulsions (65.0 ± 5.50 s) at 180 mg/kg in contrast to standard drug phenytoin, whereas the MESE model was characterized by the appearance of extensor, clonus, and flexion. The results showed that synthesized TiO2 NPs significantly reduced the time spent in each stage (15.3 ± 0.20, 16.8 ± 0.25, and 20.5 ± 0.14 s) at 180 mg/kg as compared to control groups. Furthermore, the cytotoxicity of synthesized produced TiO2 NPs demonstrated that concentrations ≤80 μg/mL were biologically compatible.

Abstract
Neurological disorders are the foremost occurring diseases across the globe resulting in progressive dysfunction, loss of neuronal structure ultimately cell death. Therefore, attention has been drawn toward the natural resources for the search of neuroprotective agents. Plant-based food bioactives have emerged as potential neuroprotective agents for the treatment of neurodegenerative disorders. This comprehensive review primarily focuses on various plant food bioactive, mechanisms, therapeutic targets, in vitro and in vivo studies in the treatment of neurological disorders to explore whether they are boon or bane for neurological disorders. In addition, the clinical perspective of plant food bioactives in neurological disorders are also highlighted. Scientific evidences point toward the enormous therapeutic efficacy of plant food bioactives in the prevention or treatment of neurological disorders. Nevertheless, identification of food bioactive components accountable for the neuroprotective effects, mechanism, clinical trials, and consolidation of information flow are warranted. Plant food bioactives primarily act by mediating through various pathways including oxidative stress, neuroinflammation, apoptosis, excitotoxicity, specific proteins, mitochondrial dysfunction, and reversing neurodegeneration and can be used for the prevention and therapy of neurodegenerative disorders. In conclusion, the plant based food bioactives are boon for neurological disorders.

[PMID: 34517803 PMCID: PMC9886799 DOI: 10.2174/1570159x19666210913120637] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 08/04/2021] [Accepted: 09/10/2021] [Indexed: 11/22/2022] Open
Abstract
Epilepsy is a devastating neurological disorder. Current anti-convulsant drugs are only effective in about 70% of patients, while the rest remain drug-resistant. Thus, alternative methods have been explored to control seizures in these drug-resistant patients. One such method may be through the utilization of fruit phytochemicals. These phytochemicals have been reported to have beneficial properties such as anti-convulsant, anti-oxidant, and anti-inflammatory activities. However, some fruits may also elicit harmful effects. This review aims to summarize and elucidate the anti- or pro-convulsant effects of fruits used in relation to seizures in hopes of providing a good therapeutic reference to epileptic patients and their carers. Three databases, SCOPUS, ScienceDirect, and PubMed, were utilized for the literature search. Based on the PRISMA guidelines, a total of 40 articles were selected for critical appraisal in this review. Overall, the extracts and phytochemicals of fruits managed to effectively reduce seizure activities in various preclinical seizure models, acting mainly through the activation of the inhibitory neurotransmission and blocking the excitatory neurotransmission. Only star fruit has been identified as a pro-convulsant fruit due to its caramboxin and oxalate compounds. Future studies should focus more on utilizing these fruits as possible treatment strategies for epilepsy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neuroprotective Traditional Chinese Medicine (TCM) has been practiced in alternative medicine from early days. TCM-derived neuroprotective compounds, such as Chrysin, Cannabidiol, Toonasinoids, and β-asaron, exert significant effectiveness's towards Parkinson's disease (PD). Further, these neuroprotective TCM showed antioxidative, anti-inflammatory, anti-tumor, anti-septic, analgesic properties. Recent research showed that the reduction in the reactive oxygen species (ROS) decreased the α-synuclein (α-syn) toxicity and enhanced the dopaminergic neuron regenerations, the main hallmarks of PD. Therefore, the neuroprotective effects of novel TCM due to its antiradical activities needed deep investigations. AIMS OF THE STUDY This review aims to enlighten the neuroprotective TCM and its components with their antioxidative properties to the scientific community for future research. METHOD The relevant information on the neuroprotective TCM was gathered from scientific databases (PubMed, Web of Science, Google Scholar, ScienceDirect, SciFinder, Wiley Online Library, ACS Publications, and CNKI). Information was also gained from MS and Ph.D. thesis, books, and online databases. The literature cited in this review dates from 2001 to June 2, 0201. RESULTS Novel therapies for PD are accessible, mostly rely on Rivastigmine and Donepezil, offers to slow down the progression of disease at an early stage but embraces lots of disadvantages. Researchers are trying to find a potential drug against PD, which is proficient at preventing or curing the disease progress, but still needed to be further identified. Oxidative insult and mitochondrial dysfunction are thought to be the main culprit of neurodegenerations. Reactive oxygen species (ROS) are the only causative agent in all interactions, leading to PD, from mitochondrial dysfunctions, α-syn aggregative toxicity, and DA neurons degenerations. It is evident from the redox balance, which seems an imperative therapeutic approach against PD and was necessary for the significant neuronal activities. CONCLUSION Our study is explaining the newly discovered TCM and their neuroprotective and antioxidative properties. But also bring up the possible treatment approaches against PD for future researchers.

Abstract
OBJECTIVES In recent times, the use of natural remedies, which are rich in varieties of vitamins and flavonoids, for treatment of inflammation has increased substantially. These natural remedies are expected to be safe and economical when compared with other conventional allopathic drugs. Thus, existing research investigated the anti-inflammatory effect of Nelumbo nucifera fruit (NNF), in view of estimating its traditional and pharmacologic use against disorders associated with pain and inflammation. MATERIALS AND METHODS To estimate the antiinflammatory effect of NNF, carrageenan-induced paw edema method was employed with equally distributed (n=7) Wistar male rats (N=35). The paw edema was measured by volume displacement method with plethysmometer. RESULTS The NNF extract significantly reduced the inflammation of the paw and decreased the edema volume in rats administered carrageenan at all doses from the 3rd to 5th hour when compared to control, whose maximum percent reduction of edema was estimated as 100 mg/kg dose (that is, 73.92% at the 5th hour after administration of carrageenan). CONCLUSION NNF exhibited a strong antiinflammatory effect, due to its phytochemical constituents, including flavonoids, saponins, and tannins, all of which synergistically exert inhibitory effects on arachidonic acid metabolism, neutrophil degranulation, and enzyme systems that promote cell proliferation and regulation of complement system. However, more preclinical and clinical evaluations are mandatory to validate these findings.

Lotusine, an alkaloid from Nelumbo nucifera (Gaertn.), attenuates doxorubicin-induced toxicity in embryonically derived H9c2 cells. In Vitro Cell Dev Biol Anim 2020; 56:367-377.

Abstract
Cardiotoxicity is the major challenge in chemotherapy with doxorubicin (DOX) or adriamycin. Doxorubicin manifests oxidative stress via an uncontrolled progression of reactive oxygen species in cardiomyocytes; thereby, dysregulation and dysfunction of myocardium thus lead to apoptosis. Several attempts have been made to overcome this side effect in patients with antioxidant-rich supplements to control the free radicals. Plant-based or plant-derived compounds pay more attention to cure such complications in patients for supporting the treatment, revitalizing or regulating the normal metabolism. Hence, our study focused on pretreatment of embryonically derived rat cardiomyocytes (H9c2) with phytocompound lotusine to prevent DOX-mediated oxidative stress. From the experiment, the DOX-exposed cells have shown morphological abnormalities such as reduced cell size, shrinkage, blebbing, and chromatin condensation, whereas no such deformities were observed in lotusine-pretreated cells even after the exposure to DOX. Increased endogenous antioxidants with reduced lipid peroxidation were observed in lotusine-pretreated cells, whereas the antioxidants were reduced along with increased lipid peroxidation in doxorubicin-exposed cells. A decreased reactive oxygen species generation was evidenced with the 2',7'-dichlorofluorescein diacetate (DCF-DA) staining method. In qPCR analysis, the lotusine-pretreated cells have mitigated doxorubicin-mediated apoptosis by downregulating the pro-apoptotic gene Bax and apoptotic executor caspase-3. It was further confirmed with the luminometric assay, which resulted in lesser luminescence in lotusine-pretreated cells, whereas higher luminescence was recorded in doxorubicin-alone-treated cells. In conclusion, the present study revealed that the lotusine pretreatment has exhibited potential cardioprotective activity against DOX-induced oxidative stress by increasing the intracellular antioxidant defense.

Abstract
The aim of the study was to evaluate the anticonvulsant and neuroprotective activity of Cocculus laurifolius D.C leaves in albino wistar rats against strychnine induced convulsions. Initially the extract was investigated for acute oral toxicity testing in order to examine any signs of toxicity and mortality. For anticonvulsant activity, the ethanolic extract was evaluated at doses 200 and 400 mg/kg, p.o. against strychnine induced convulsions model, at 1, 7, 15 and 30th day of treatment. Meanwhile, the neuroprotective effect of the extract was investigated via histopathological assessment. Cocculus laurifolius (200 and 400 mg/kg, p.o.) exhibited anticonvulsant activity as indicated by significant delay in the onset of convulsions and time to death after strychnine induced convulsions. Similarly, significant reduction in the duration of convulsions and percentage of mortality was observed by ethanolic extract (200 and 400 mg/kg p.o.) at 1, 7, 15 and 30th day of test sessions. Furthermore, Cocculus laurifolius leaves (200 and 400 mg/kg p.o.) also exhibited neuroprotective effect with considerable preserved neuronal structures and significant decrease in neuronal apoptosis, in comparison with control. The results obtained from the present study indicate that ethanolic extract of Cocculus laurifolius leaves possess potential anticonvulsant and neuroprotective effect against strychnine induced convulsions. Therefore, it can be concluded that Cocculus laurifolius leaves may be a valuable in management of epilepsy, however further studies are required on large number of animals to confirm these findings.

Abstract
From prehistoric time till today herbal medications are supposed to have neuroprotective effects both by inhibiting acetyl cholinesterase enzyme or antioxidant ability and are also affordable. Thus extensive studies are necessary to investigate the pharmacological effects of herbal plants. The goal of the present study was to ascertain the outcome of Nelumbo nucifera fruit (NNF) on scopolamine induced amnestic rats along with motor coordination in mice in order to explore its pharmacological use in disorders like Alzheimer's disease (AD). The effect of NNF on learning and memory was assessed by Morris water maze test using 35 Wister rats weighing 200-230 g evenly divided in to five groups. While motor coordination was assessed using Rot rod test, 35 male locally bred albino mice weighing 20-25 g were equally divided in to five groups. Group I was kept as control (10 ml/kg gum tragacanth). Group II, III and IV were labeled as treated groups (NNF 50, 100 and 200 mg/kg). Group V served as reference group (piracetam 200 mg/kg). All drugs were given by oral route as a single dose for 15 days in both experiments to rats and mice, however scopolamine (1 mg/kg IP) was used in Morris water maze test 40 min after the administration of drugs to rats for the induction of amnesia. In Morris water maze test, N. nucifera fruit caused highly significant and significant decrease in escape latency in the amnestic rats at 200 and 100 mg/kg as compared to control. In Rota rod test, N. nucifera fruit did not exhibit any notable changes in the riding time at any dose as compared to control. N. nucifera fruit have demonstrated ameliorating effects on memory without affecting muscle coordination. Hence NNF seems to have great potential for therapeutic application in memory disorders, such as AD which may be due to its ability to enhance cholinergic neurotransmission and exerting antioxidant effect and thus encourage more preclinical and clinical trials in this field.
