[PMID: 39029440 DOI: 10.1016/j.eplepsyres.2024.107419] [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: 12/20/2023] [Revised: 04/23/2024] [Accepted: 07/14/2024] [Indexed: 07/21/2024]
Abstract
The aim of the present study was to develop a novel formulation of berberine (BBR) and demonstrate its anti-seizure effect in pentylenetetrazole (PTZ) induced kindling model in rats. Nanoparticles of BBR were formulated using Poly Lactic-co-Glycolic Acid (PLGA) as a polymer. Emulsification and solvent evaporation technique was used. PTZ induced kindling model in male wistar rat was used to demonstrate the anti-seizure effect of nano-BBR. The particle size obtained for the final formulation was 242.8 ± 67.35 nm with a PDI of 0.140 ± 0.01. PLGA encapsulated BBR nanoparticles showed the % encapsulation efficiency of 87.33 ± 2.42 % and % drug loading of 48.47 ± 1.34 %. In-vitro drug release data showed sustained release of nano-BBR as compared to BBR. Kinetic study data showed increase in AUC of nano-BBR (35,429.46 h.ng/ml) as compared to BBR (28,211.07 h.ng/ml). Cmax for nano- BBR (2251.90 ng/ml) is approximately 1.6 times greater than BBR (1505.50 ng/ml). Nano- BBR has shown the significant effect on the seizure score. The PLGA encapsulated berberine nanoparticles were prepared by an innovative simple method and offers excellent potential as an antiepileptic agent.

Natural product-derived therapies for treating drug-resistant epilepsies: From ethnopharmacology to evidence-based medicine. JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116740. [PMID: 37315641 DOI: 10.1016/j.jep.2023.116740] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 05/17/2023] [Accepted: 06/04/2023] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Epilepsy is one of the most prevalent neurological human diseases, affecting 1% of the population in all age groups. Despite the availability of over 25 anti-seizure medications (ASMs), which are approved in most industrialized countries, approximately 30% of epilepsy patients still experience seizures that are resistant to these drugs. Since ASMs target only limited number of neurochemical mechanisms, drug-resistant epilepsy (DRE) is not only an unmet medical need, but also a formidable challenge in drug discovery. AIM In this review, we examine recently approved epilepsy drugs based on natural product (NP) such as cannabidiol (CBD) and rapamycin, as well as NP-based epilepsy drug candidates still in clinical development, such as huperzine A. We also critically evaluate the therapeutic potential of botanical drugs as polytherapy or adjunct therapy specifically for DRE. METHODS Articles related to ethnopharmacological anti-epileptic medicines and NPs in treating all forms of epilepsy were collected from PubMed and Scopus using keywords related to epilepsy, DRE, herbal medicines, and NPs. The database clinicaltrials.gov was used to find ongoing, terminated and planned clinical trials using herbal medicines or NPs in epilepsy treatment. RESULTS A comprehensive review on anti-epileptic herbal drugs and natural products from the ethnomedical literature is provided. We discuss the ethnomedical context of recently approved drugs and drug candidates derived from NPs, including CBD, rapamycin, and huperzine A. Recently published studies on natural products with preclinical efficacy in animal models of DRE are summarized. Moreover, we highlight that natural products capable of pharmacologically activating the vagus nerve (VN), such as CBD, may be therapeutically useful to treat DRE. CONCLUSIONS The review highlights that herbal drugs utilized in traditional medicine offer a valuable source of potential anti-epileptic drug candidates with novel mechanisms of action, and with clinical promise for the treatment of drug-resistant epilepsy (DRE). Moreover, recently developed NP-based anti-seizure medications (ASMs) indicate the translational potential of metabolites of plant, microbial, fungal and animal origin.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ferula gummosa Boiss., known in Persian as "Baridje," belongs to the Apiaceae family. All parts of this plant, especially the root, contain galbanum. Galbanum, the oleo-gum resin of F. gummosa, is one of the essential traditional herbal medicines in Iran, which is used as a tonic for epilepsy and chorea, memory enhancement, gastrointestinal diseases, and wound healing. AIM OF THE STUDY We investigated the toxicity, anticonvulsant effects, and molecular modeling of the essential oil (EO) distilled from the oleo-gum resin of F. gummosa. MATERIALS AND METHODS Gas chromatography-mass spectrometry was used to identify the EO components. The cytotoxicity of EO on HepG2 cell lines was assessed by the MTT method. Male mice were arranged as follows: negative control groups (sunflower oil (10 ml/kg, i.p.) or saline (10 ml/kg, p.o.)), EO groups (0.5, 1, 1.5, and 2.5 ml/kg, p.o.), and positive control groups (ethosuximide (150 mg/kg, p.o.) or diazepam (1.0 or 2 mg/kg, i.p.)). The motor coordination and neurotoxicity of EO were studied using the rota-rod test. Open-field, novel object recognition, and passive avoidance learning tests were used to investigate the effect of EO on locomotor activity and memory function. An acute pentylenetetrazole-induced seizure model was utilized to evaluate the anticonvulsant properties of the EO. The interaction of the EO main components with the GABAA receptor was investigated by coarse-grained molecular dynamics simulations. RESULTS β-pinene, sabinene, α-pinene, and ρ-cymene were the main components of EO. The IC50 of the EO at 24, 48, and 72 h was found to be 59.90, 12.96, and 3.93 μl/ml, respectively. No adverse effects were observed in memory, motor coordination, and locomotor activity in mice treated with EO. Administration of EO (1, 1.5, and 2.5 ml/kg) improved survival rates in mice receiving pentylenetetrazole (PTZ; to induce an epileptic seizure). Sabinene was able to bind to the binding site of benzodiazepines at the GABAA receptor. CONCLUSIONS Acute treatment with the EO of F. gummosa caused antiepileptic effects and could effectively increase the survival rate in PTZ-treated mice with no significant toxicity.

Abstract
Pliny the Elder was a prolific Roman author, naturalist, and military leader. Yet, his impact on modern-day neuroscience, psychiatry, and neurology has been little explored. Here, we aimed to trace the origins of our current understanding of the brain in ancient Rome through Pliny and his work, Natural History. As his magnum opus, this 37-book tome catalogs the facts and observations of natural life collected by Pliny, reflecting the knowledge of his time. Following the cephalocentric school of thought, Pliny places the brain as an agent for consciousness and details its diseases. Further, we explore Pliny's methods, which allow him to build a thorough collection of clinical descriptions and remedies. This body of work serves as an important lesson for future neuroscientists on the power of observation, the role of the humanities, and the necessity of understanding the origin of modern scientific thinking.

Abstract
Abstract
Background
The aim was to evaluate the protective effect of hydroalcoholic extract of Anacyclus pyrethrum root (APE) against pentylenetetrazole (PTZ) drug which is used for inducing epileptic seizures in animal model.
Results
50 male rats were divided: control (without any intervention), positive control 1st (received PTZ 60 mg/kg, IP), first experimental group (PTZ + Extract 500 mg/kg, gavages, 30 min before PTZ), positive control 2nd (PTZ + Phaclofen, 200 µg/µl, ICV), and second experimental group (PTZ + extract 500 mg/kg, gavage, 30 min before PTZ + Phaclofen 200 µg/µl, ICV). Several parameters were assessed during 20 min and followed up for 1.5 h. Then, the data were analyzed. APE with a dose of 500 mg/kg increased the latency time of seizures in the first experimental group, compared to the positive control 1st, also, comparison of different groups in terms of Seizure Score at the 1st time (severity of first attack) had no significant difference (P-value = 0.51, P-value = 0.34). The mean of seizure attacks (event number) was significant between the first and second positive control groups (P-value = 0.01) and also between the second positive control and the first experimental group (P-value = 0.011). Significant changes were observed in the mean score of the first and second positive control groups (P-value = 0.001) and the first experimental and second positive control groups (P-value = 0.003). In addition, the second experimental group had significant changes compared to the first positive control group (P-value = 0.014), However, no significant changes were observed between the positive control and experimental groups in terms of the severity of seizures.
Conclusion
Results have shown both blocked GABAergic receptors A and B involved in epileptic seizures. In addition, APE root increased delay time of epileptic seizures, as well as reduces epileptic seizure in dose response state.

Abstract
Status epilepticus (SE) can result in an overproduction of hydrogen peroxide (H2O2), which contributes to oxidative stress and brain injury during different phases of epileptogenesis and seizures. The purpose of this study was to evaluate the effects of ellagic acid and allopurinol administered after SE on H2O2 concentrations, electrical activity and GFAP immunoreactivity in the hippocampus of rats evaluated on Day 18 after SE. H2O2 levels were measured using an online technique with high temporal resolution and simultaneous electrical activity recording. For this purpose, the lateral ventricles of male Wistar rats (200-250 g) were injected with pilocarpine (2.4 mg/2 µl) to induce SE. After SE, rats were injected with ellagic acid (50 mg/kg i.p., and two additional doses at 24 and 48 h) or allopurinol (50 mg/kg i.p., single dose). Administration of ellagic acid or allopurinol after SE significantly reduced the H2O2 concentrations and decreased the presence of epileptiform activity and GFAP immunoreactivity in the hippocampus 18 days after SE. In conclusion, the administration of antioxidants potentially reduces oxidative stress, which indicates the possible attenuation of the neurobiological consequences after SE.

Abstract
The anticonvulsive potential of proteins extracted from Orthosiphon stamineus leaves (OSLP) has never been elucidated in zebrafish (Danio rerio). This study thus aims to elucidate the anticonvulsive potential of OSLP in pentylenetetrazol (PTZ)-induced seizure model. Physical changes (seizure score and seizure onset time, behavior, locomotor) and neurotransmitter analysis were elucidated to assess the pharmacological activity. The protective mechanism of OSLP on brain was also studied using mass spectrometry-based label-free proteomic quantification (LFQ) and bioinformatics. OSLP was found to be safe up to 800 µg/kg and pre-treatment with OSLP (800 µg/kg, i.p., 30 min) decreased the frequency of convulsive activities (lower seizure score and prolonged seizure onset time), improved locomotor behaviors (reduced erratic swimming movements and bottom-dwelling habit), and lowered the excitatory neurotransmitter (glutamate). Pre-treatment with OSLP increased protein Complexin 2 (Cplx 2) expression in the zebrafish brain. Cplx2 is an important regulator in the trans-SNARE complex which is required during the vesicle priming phase in the calcium-dependent synaptic vesicle exocytosis. Findings in this study collectively suggests that OSLP could be regulating the release of neurotransmitters via calcium-dependent synaptic vesicle exocytosis mediated by the "Synaptic Vesicle Cycle" pathway. OSLP's anticonvulsive actions could be acting differently from diazepam (DZP) and with that, it might not produce the similar cognitive insults such as DZP.

Abstract
Orthosiphon stamineus (OS) or Orthosiphon aristatus var. aristatus (OAA) is commonly known as cat's whiskers or "misai kucing". It is an herbaceous shrub that is popular in many different traditional and complementary medicinal systems. Its popularity has been justified by the plethora of studies that have shown that the secondary metabolites of the plant has effects that range from anti-inflammatory and gastroprotective to anorexic and antihypertensive. As such, OS could also be a potential treatment for Central Nervous System (CNS) disorders. However, a cohesive synthesis of the protective actions of OS was lacking. This systematic review was therefore commenced to elaborate on the various protective mechanisms of OS in the CNS. The PRISMA model was used and five databases (Google Scholar, SCOPUS, SpringerLink, ScienceDirect, and PubMed) were searched with relevant keywords to finally identify four articles that met the inclusion criteria. The articles described the protective effects of OS extracts on Alzheimer's disease, epilepsy, learning and memory, oxidative stress, and neurotoxicity. All the articles found were experimental or preclinical studies on animal models or in vitro systems. The reported activities demonstrated that OS could be a potential neuroprotective agent and might improve CNS conditions like neurodegeneration, neuroinflammation, and oxidative stress.

Nanoformulated ellagic acid ameliorates pentylenetetrazol-induced experimental epileptic seizures by modulating oxidative stress, inflammatory cytokines and apoptosis in the brains of male mice. Metab Brain Dis 2020; 35:385-399.

Abstract
The present study evaluated the neuroprotective and antiepileptic efficacy of ellagic acid (EA) encapsulated in calcium-alginate nanoparticles (Ca2+-ALG NPs) in pentylenetetrazol (PTZ)-induced seizures in male mice. EA was encapsulated in ALG NPs using a nanospray drying method followed by ionotropic crosslinking with Ca2+. Characterization of the developed Ca2+-crosslinked EA-ALG NPs showed spherical, high stability NPs; successful loading of EA within crosslinked ALG NPs; and sustained release of EA. Male Swiss albino mice were divided into ten groups as follows; Group I- (control), Group II (50 mg EA /kg) - (EA), Group III polyethylene glycol (PEG), Group IV EA NPs (50 mg/kg) - (EA NP), Group (50 mg/kg alginate) V void V NPs - (void NPs), Group VI: (37.5 PTZ mg/kg) -(PTZ), Group VII: PTZ and EA - (PTZ-EA). Group VIII: animals received PTZ and PEG concurrently (PTZ-PEG). Group IX; animals received PTZ and void NPs concurrently - (PTZ-void). Group X: animals received PTZ and EA NPs concurrently (PTZ-EA NPs). PTZ was used to induce experimental epilepsy. Ca2+-ALG NPs prevented seizures throughout the experimental period and had a more prominent effect than free EA did. Ca2+-ALG NPs prevented increased glutamate, decreased GABA concentrations and ameliorated increased amyloid-β and homocysteine levels in the serum and brain. Ca2+-EA-ALG NPs were superior to free EA in improving increased IL-6 and TNF-α. Ca2+-ALG NPs ameliorated PTZ-induced oxidative stress, as evidenced by decreased 4HNE levels and enhanced GSH, GR and GPx levels in the brain. These changes were accompanied by amelioration of apoptosis and its regulating proteins, including Cytochrome C, P53, Bax, Bcl2 and caspase-3 and caspase-9, and protected against DNA damage. Histological examination of the hippocampus confirmed that the neuroprotective effect of Ca2+-EA-ALG NPs was superior and more effective than that of free EA.
