Yufeng Ningxin Tablet (YNT) is a traditional Chinese medicine formula, that has been used clinically to treat migraine for many years. It composed of one herb Pueraria lobata var. (Willd.) Ohwi (Relevant name: Gegen). Previously, it recorded by doctor Gegen could be as migraine. However, the underlying mechanism action remains investigated.It was explore effect and YNT on based network pharmacology experimental verification.First, with pharmacology, effective chemical components target genes were filtrated, YNT-compound-migraine-targets constructed. The protein-protein interaction (PPI) literature reports combined identify potential targets in treatment Then, representative compounds characterized LC-MS/MS major identified. Finally, prediction results verified animal cell experiments.7 bioactive act 97 targets. 5 comprehensively YNT. key therapeutic pathways collected including 5-HT, CGRP, inflammation nociceptive factors, NF-κB signaling pathway. Animal experiments showed increase expression level 5-HT reduce NF-κB, c-fos IL-1β. inhibit LPS-induced neuroinflammation BV2 cells vitro. Western blotting analysis inhibited phospho-NF-κB levels.It first time verify consistency between metabolic active predicted pharmacology. Meanwhile, studied combining vitro vivo experiments.

Migraine is a severely debilitating disorder that affects millions of people worldwide. Studies have indicated activation protease-activated receptor-2 (PAR2) in the dura mater causes headache responses preclinical models. It also well known vasodilators such as nitric oxide (NO) donors can trigger migraine attacks patients but not controls. In current study we examined whether PAR2 priming to NO donor glyceryl trinitrate (GTN).A behavioral model was used where stimuli (PAR2 agonists: 2at-LIGRL-NH2 (2AT) or neutrophil elastase (NE); and IL-6) were applied mouse through an injection made at intersection lamdoidal sagittal sutures on skull. Following dural injection, periorbital von Frey thresholds facial grimace measured until their return baseline. GTN then given by intraperitoneal hypersensitivity observed they returned baseline.We found application selective agonist onto headache-related WT PAR2-/- mice with no differences between sexes. Additionally, 2AT caused (1 mg/kg) 14 days after primary stimulation. showed GTN. We tested endogenous protease elastase, which cleave activate PAR2. Dural both acute mice. Finally, show IL-6 identical mice, indicating does act this model.These results indicate meninges cause donor, support further exploration novel therapeutic target for migraine.

Neurological diseases have consistently represented a significant challenge in both clinical treatment and scientific research. As research has progressed, the significance of mitochondria pathogenesis progression neurological become increasingly prominent. Mitochondria serve not only as source energy, but also regulators cellular growth death. Both oxidative stress mitophagy are intimately associated with mitochondria, there is mounting evidence that exert pivotal regulatory influence on diseases. In recent years, been notable rise prevalence cerebral ischemia/reperfusion injury (CI/RI), vascular dementia (VaD), Alzheimer’s disease (AD), which collectively represent public health concern. Reduced levels observed CI/RI, VaD AD. The improvement pathology demonstrated through increase levels. CI/RI results tissue ischemia hypoxia, causes stress, disruption blood–brain barrier (BBB) damage to vasculature. BBB may induce or exacerbate some extent. addition, inadequate perfusion due altered function accumulation amyloid β (Aβ) thereby contributing exacerbating AD pathology. Intravenous plasminogen activator (tPA; alteplase) endovascular thrombectomy effective treatments for stroke. However, narrow window opportunity administration tPA thrombectomy, markedly elevated incidence disability among patients CI/RI. It regrettable currently no still specific drugs Despite availability U.S. Food Drug Administration (FDA)-approved first-line AD, including memantine, donepezil hydrochloride, galantamine, these agents do fundamentally block pathological process this paper, we undertake review mechanisms disorders, summary trials conducted proposal new strategy targeted disorders based stress.

Scope The anti‐neuroinflammatory effect of a novel quinolyl‐substituted analogue resveratrol (RV01) on lipopolysaccharide (LPS)‐induced microglial activation is investigated, as well the possible underlying mechanisms. Methods and results Cell viability measured using an MTT assay. Nitric oxide (NO) release determined by nitrite interaction between RV01 inducible nitric synthase (iNOS) studied molecular docking. Free radical scavenging activity reactive oxygen species (ROS) production are DPPH reduction assay DCFH‐DA Pretreatment with (1–30 µ m ) prior to LPS (1 µg mL –1 stimulation decreased NO iNOS expression without observable cytotoxicity. reduced mRNA levels secretion tumor necrosis factor‐α (TNF‐α) interleukin‐6 (IL‐6). also inhibited LPS‐induced ROS nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activation. Furthermore, decreases protein toll‐like receptor 4 (TLR4) inhibits mitogen‐activated kinase (MAPK) nuclear transcription factor‐κB (NF‐κB) signaling pathways. Additionally, conditioned medium from microglia co‐treated alleviates death SH‐SY5Y cells induced activated N9 cells. Lastly, mouse neuroinflammation model further used confirm in vivo. Conclusion These show that suppresses microglia‐mediated protects neurons inflammatory damage, which indicates has great potential nutritional preventive strategy for neuroinflammation‐related diseases.
