Neutrophil extracellular traps (NETs) play an important role in the inflammatory response and progressive joint destruction rheumatoid arthritis (RA). Rhaponticin (Rha) is a stilbene glycoside compound with antioxidant anti-inflammatory effects. This study aimed to investigate therapeutic potential of Rha RA, specific focus on its effects NETs underlying mechanisms Rha. formation induced by phorbol 12-myristate 13-acetate (PMA) collagen-induced (CIA) mouse model were implemented evaluate pharmacological vitro vivo. The mechanism improving RA was screened verified using SuperPred DisGeNET databases. Disulfiram (a GSDMD inhibitor) S100a8cre GSDMDfl/fl mice used confirm whether key findings demonstrate that significantly inhibited reactive oxygen species production PMA-activated neutrophils. In vivo, treatment relieved symptoms CIA production. Mechanistically, reduced via inhibition NLRP3/GSDMD activation. Neutrophil-specific depletion eliminated vitro. alleviated inflammation vivo Overall, our results indicated exerts protective effect against inhibiting through pathway. this provide new strategies for treating RA.

Rhizomes of Drynaria quercifolia have long been traditionally used to manage rheumatic pain. However, there is limited research supporting this traditional practice and insufficient evidence demonstrating the molecular mechanisms action plant-derived bioactives in rheumatoid arthritis (RA). The current study aims identify effective components methanol rhizome extract (DME) their probable pharmacological alleviating Rheumatoid Arthritis (RA) using network-pharmacology, docking, molecular-dynamics simulations, gene expression-based validation. Gas chromatography-mass spectrometry (GC-MS) based screening identified 41 volatile phytocomponents from DME having drug-like potentiality. Network pharmacology-based revealed 117 therapeutic targets for RA which 11 as core targets. Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment analysis indicated that key target genes were mostly enriched inflammatory response associated with multiple signalling pathways. Molecular docking dynamics studies proteins like serine/threonine-protein kinase (AKT1), peroxisome proliferator-activated receptor alpha (PPARA), gamma (PPARG), exhibited strong binding affinity stable interactions present DME. For experimental verification FCA (Freund's complete adjuvant)-induced chronic model employed further investigation. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) results validated significantly (p ≤ 0.05) regulate expression AKT PPARG model. Moreover, confirmed downregulated pro-inflammatory mediators COX-2, IL-6 TNF-α at protein levels also normalized different oxidative stress parameters both low high dose groups DME-treated arthritic animals. In conclusion, network-based silico approach probably act a synergistic way modulate RA, was by studies. Therefore, could be potential alternative immunomodulatory therapies combat related conditions.
