However, research on the exact therapeutic agents and molecular mechanisms of CP is still unclear. In this study, we investigated Rabdosichuanin C (RC) to attenuate lipopolysaccharide (LPS)\u2010induced inflammatory damage in RAW264.7 cells by a combination of targeted virtual screening and in vitro activity assay and further clarified its molecular mechanism of action centering on the I\u03baB\/nuclear factor kappa B (NF\u2010\u03baB) pathway. Molecular docking and pharmacophore simulation methods were used to screen compounds with I\u03baB inhibitory effects. Expression of genes and proteins related to the I\u03baB\/NF\u2010\u03baB signaling pathway by RC in LPS\u2010induced inflammatory injury model of RAW264.7 cells was detected by PCR, enzyme\u2010linked immunosorbent assay, and Western blot. The docking of RC with I\u03baB protein showed good binding energy, and pharmacophore simulations further confirmed the active effect of RC in inhibiting I\u03baB protein. RC intervention in LPS\u2010induced RAW264.7 cells significantly reduced the expression levels of inflammatory factors tumor necrosis factor\u2010\u03b1, interleukins\u20106, iNOS, and CD\u201086 at the messenger RNA and protein levels, downregulated I\u03baB, p65 protein phosphorylation levels, and significantly inhibited I\u03baB\/NF\u2010\u03baB signaling pathway activation. Virtual screening provided us with an effective method to rapidly identify compounds RC that target inhibit the action of I\u03baB, and the activity results showed that RC inhibits NF\u2010\u03baB signaling pathway activation. It is suggested that RC may play a role in the treatment of CP by inhibiting the I\u03baB\/NF\u2010\u03baB signaling pathway.<\/jats:p>","DOI":"10.1002\/jcb.30474","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T11:49:26Z","timestamp":1697629766000},"page":"1667-1684","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Rabdosichuanin
