PANoptosis is a novel type of programmed cell death. Nevertheless, The mechanisms of DCHD against SALI via anti-PANoptosis remains unknown.Methods: First, we identified the intersecting targets among DCHD, SALI, and PANoptosis using relevant databases and published literature. Then, protein-protein interaction (PPI) network, molecular docking, and functional enrichment analysis were conducted. In vivo, cecal ligation and puncture (CLP) was used to construct a sepsis mouse model, and the therapeutic effects of DCHD on SALI were evaluated using hematoxylin and eosin (H&E) staining, quantitative real-time PCR (qRT-PCR), and ELISA. Finally, qRT-PCR, immunofluorescence staining, and Western blotting were used to verify the effect of DCHD-containing serum (DCHD-DS) on LPS-induced RAW 264.7 macrophages in vitro.Results: 82 intersecting targets were identified by mapping the targets of DCHD, SALI, and PANoptosis. Enrichment analysis showed that DCHD against SALI via anti-PANoptosis by modulating tumor necrosis factor (TNF), AGE-RAGE, phosphoinositide 3-kinase (PI3K)-AKT, and Toll-like receptor signaling pathways by targeting Casp3, cellular tumor antigen p53 (TP53), B-cell lymphoma 2 (Bcl2), toll-like receptor-4 (TLR4), STAT3, STAT1, RELA, NF-κB1, myeloid cell leukemia-1 (MCL1), JUN, IL-1β, HSP90AA1, Casp9, Casp8, and Bcl2l1. Molecular docking analysis revealed that the key components of DCHD have a high binding affinity to the core targets. In vivo, DCHD improved lung histopathological injury, reduced inflammatory factor expression, and alleviated oxidative stress injury in lung tissues. In vitro, DCHD-DS alleviated cell morphology changes, the release of pro-inflammatory factors, and p65 nucleus aggregation. Furthermore, we verified that DCHD-DS inhibited PANoptosis by downregulating the PI3K/AKT/NF-κB signalling pathway.Conclusion: DCHD attenuates SALI by inhibiting PANoptosis via control of the PI3K/AKT/NF-κB pathway. Our study provides a solid foundation for investigating the mechanisms of DCHD and its clinical application in the treatment of SALI.
