Ferroptosis, driven by arachidonic acid (AA) metabolism dysregulation, plays a critical role in sepsis-related organ damage. This study aimed to identify key regulators in the AA metabolism-ferroptosis axis and validate natural product-derived modulators. Through bioinformatic analyses of public datasets, we identified ALOX15 as a core shared regulator linking AA metabolism to ferroptosis in sepsis-induced MOI. Further, baicalin and baicalein, major active components of Scutellaria baicalensis, were found to directly bind to human and murine ALOX15 via molecular docking, which was validated by cellular thermal shift assay (CETSA) and drug affinity responsive target stability assay (DARTS). These findings demonstrated ALOX15 as a mediator of sepsis-induced MOI and revealed baicalin/baicalein as direct ALOX15 ligands that might inhibit ferroptosis. Our work provides a target-driven rationale for the clinical application of S. baicalensis in sepsis therapy.
