Summary	Oosporein Dibenzoquinone fungal metabolite with antimicrobial and metal-chelating activities.
Details	Oosporein is a red dibenzoquinone secondary metabolite produced by fungi such as Beauveria, Chaetomium, and Phlebia species. Structurally characterized as a symmetric dibenzoquinone, it exhibits redox-active antimicrobial properties and contributes to fungal virulence in insects by modulating immune responses rather than acting as a direct toxin. Oosporein also functions as a metal chelator, promoting aluminum detoxification and enhancing plant growth under stress conditions. Its diverse biological activities make it a useful model for studying quinone-mediated redox biology, fungal pathogenicity, and metal stress responses.
Mechanism	Redox-active dibenzoquinone that chelates metal ions and induces oxidative stress.
Primary Target	Redox-active quinone systems
Pathway	Redox signaling pathway; Metal stress response
Chemical Class	Dibenzoquinone
