Wielokierunkowe działanie ekstraktu liści moryki lékařskiej w leczeniu padaczko-podobnych zaburzeń neurologicznych indukowanych PTZ u samców szczurów: badania doświadczalne i analizy komputerowe
A multi-target approach using Moringa oleifera leaf extract in ameliorating PTZ-induced epilepsy-like neurobehavior in male rats: in vivo and in silico study
W skrócie
Badacze testowali ekstrakt z liści moryki lékařskiej jako potencjalny lek na padaczkę, ponieważ istniejące leki przeciwpadaczkowe często powodują niepożądane skutki uboczne. Ekstrakt zmniejszył objawy padaczko-podobne u szczurów, poprawiając ochronę mózgu przed uszkodzeniami, zmniejszając stany zapalne i przywracając prawidłową pracę neurotransmiterów. Wyniki sugerują, że moryka lékařska mogłaby być obiecującym naturalnym źródłem nowych leków przeciwpadaczkowych o mniej skutkach ubocznych.
Oryginalny abstract (angielski)
Although a variety of antiepileptic medications are available, their administration often leads to undesirable side effects. In the present study, we investigated the effect of Moringa oleifera leaf extract (MOLE) against neurodegenerative pathophysiology relevant to PTZ-induced epilepsy-like neurobehavior in the hippocampus of rats. Forty male rats were allocated into four groups: control group, MOLE group, PTZ group, and PTZ plus MOLE group. MOLE (300 mg/kg) was administered orally for 35 days, while PTZ (40 mg/kg) was injected intraperitoneally in nine doses on alternate days, commencing on the 18th day. Phytochemical analysis using GC-MS and molecular docking was performed. Animals were behaviorally assessed using open field and elevated plus maze tests. The hippocampal tissue was evaluated for malondialdehyde, nitric oxide, reduced glutathione, glutathione peroxidase, superoxide dismutase, catalase, tumor necrosis factor-α, interleukin-1β and 6, acetylcholine, acetylcholinesterase, gamma-aminobutyric acid, glutamate, and monoamine oxidase. NF-kB expression, histopathological alterations, caspase-3, and GFAP immunoreactivity were investigated. The GC-MS analysis revealed the presence of various phytochemicals. MOLE attenuated PTZ-induced behavioral changes and improved the oxidant/antioxidant status of the hippocampus. MOLE also reduced the pro-inflammatory cytokines, modulated the neurochemicals, and regulated the expression of NF-κB. Furthermore, MOLE improved the histopathological and the immunohistochemical deteriorations in the hippocampus. Molecular docking analysis showed robust binding affinities for the major phytochemicals to proteins involved in neuroinflammation, oxidative stress, and regulation of neurotransmission. These findings highlight the efficacy of MOLE as a potential multi-target approach against PTZ-induced epilepsy-like neurobehavior, attributed to its diverse bioactive phytochemicals with antioxidative, anti-inflammatory, neuromodulator, and NF-κB regulatory properties.
