The potential effects of rhapontigenin (Rha), a natural compound with antioxidant and anti-inflammatory properties, have not been directly examined in SA-AKI. HK-2 cells were pretreated with Rha for 3 h, followed by stimulation with 10 ng/mL LPS for 24 h to establish an in vitro sepsis-associated injury model. Cell viability was assessed by CCK-8. Ferroptosis-related changes were evaluated by measuring GPX4 and xCT expression, intracellular Fe2+, ROS, MDA, and BODIPY-C11-detected lipid ROS. Erastin and ferrostatin-1 (Fer-1) were used for pharmacological intervention. Inflammatory cytokines (IL-1β, IL-6, and TNF-α) were quantified by ELISA. NF-κB activation was assessed by the p-NF-κB/NF-κB and p-IκBα/IκBα ratios and p65 nuclear localization, with RANKL used as an NF-κB activator. In vivo, male C57BL/6J mice underwent cecal ligation and puncture (CLP) to induce SA-AKI. The effects of Rha on kidney histology, renal injury markers, ferroptosis-related indices, inflammatory cytokines, and NF-κB signaling were evaluated.
