Discovery of Virulence Attenuator of Chromobacterium violaceum CV026 From Marine‐Derived Fungus Aspergillus ochraceus LSD‐13 by Inhibiting Quorum Sensing and Destroying Biofilm

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Targeted quorum‐sensing (QS) represents a promising approach to combat multidrug‐resistant infections. In this study, an undescribed pyrazine derivative 5‐isobutyryl‐1,4‐dihydropyrazine‐2,3‐dione (1) together with three known compounds (2–4) are isolated from the marine‐derived fungus Aspergillus ochraceus LSD‐13.
